Abstract: However, the actual situation is that the construction of hot melt road marking machine is much more complex than that of normal temperature marking. 1. During the construction of the hot melt road marking machine, it is necessary to heat the powdery hot melt road marking machine coating to a high temperature of 180-200 ℃ and melt it into a liquid before use.

Many customers who have not been exposed to the construction of the overheated road marking machine have the misconception that the hot melt road marking machine, like cold spraying at room temperature, can only be used for construction with one hot melt road marking machine. But in reality, the construction of hot melt road marking machine is much more complex than that of normal temperature road marking.

1. During the construction of the hot melt road marking machine, the powdered hot melt road marking machine coating needs to be heated to a high temperature of 180-200 ℃ and melted into liquid before use. To ensure construction safety, when using a small hot melt road marking machine alone, the marking device should be used separately from the heating equipment for melting coating to avoid unnecessary burns and greatly improve melting efficiency.

2. In a batch of road marking construction teams, the hot melt road marking machines to be used include: hydraulic double tank thermoplastic preheater, LXD860 advanced hand push road marking machine, hand pushing pre marking machine, etc. Among them, the recommended hydraulic double cylinder hot melt preheater is the hydraulic double cylinder hot melt preheater. This utility model adopts a truck mounted hot melt preheater, which is convenient for transportation.

3. At the same time, it has the characteristics of high melt efficiency, good melt quality, less fuel use, energy conservation and environmental protection, simple operation, safety and reliability. In combination with manual marking machines, it is very efficient for the construction of yellow, white, and hot melt flat long solid marking lines and short dashed marking lines.



During the construction of the road marking machine, the road surface should be cleaned: special personnel should be arranged to clean the road surface to ensure that it is clean and free of obvious dust. (2) Measurement and setting out: When the road surface is clean, mark it according to the design drawing, then select white latex material to discharge the curb line, and mark the line after checking for accuracy. (3) road Marking machine marking:

a: Add the hot melt paint to the hot melt device and heat it evenly to the appropriate temperature

b: The placed waterline side is specially coated with a uniform undercoating agent to ensure better adhesion between the road surface and the markings, and to isolate underground moisture and prevent the markings from falling off after construction.

c: In a hand propelled construction vehicle, the hot melt coating that has melted to a usable state is loaded into the vehicle, and an appropriate amount of glass beads are placed in the body of the vehicle. Adjust the flow rate, and after the bottom oil dries to a suitable degree, proceed with formal construction. Using the waterline as the base to ensure construction quality.

d: The coating thickness of lane edges, lane boundaries, guide arrows, road centerline, warning signs, etc. is 1.5-2.0mm, and the thickness of deceleration signs is 5mm. The surface glass beads should be evenly distributed, and the marked lines should have good visibility, consistent width, consistent spacing, flush edges, good reflective effect, and firmly combined with the road surface. Cleaning: During construction, cleaning should be carried out during marking to ensure that there is no throwing, sprinkling, dripping, leakage, or pollution, and the equipment is free from oil or water leakage. The construction team shall carry out construction at a certain distance, promptly clean the road markings on site, maintain the cleanliness of the road surface, and avoid pollution.

Abstract: If the quantity of marking work is not large, such as the re marking of old lines in some sections, ordinary hand pushed or hand assisted hot melt road marking machines can be used. Due to the small size, flexible construction, and convenient transportation of the small heat road marking machine.

If the quantity of marking work is not large, such as the re marking of old lines in some sections, ordinary hand pushed or hand held hot melt road marking machines can be used. Due to the small size, flexible construction, and convenient transportation of the small heat road marking machine, the construction team can quickly rush to the construction section to complete the construction. Experienced construction teams all know that the quality of markings is closely related to many factors, such as road environment, marking paint quality, road quality, air humidity during construction, temperature, and so on. The road marking machine, although one of the important factors affecting the quality of marking, is not a decisive factor. The quality of the road marking machine determines the efficiency of marking construction, and its function is to greatly save users time and labor costs. A driving road marking machine can construct an average of 10 kilometers per hour, while a manual road marking machine can only work for 5-6 kilometers per day for 8 hours.

Taking a 100 kilometer highway as an example, using a driving road marking machine took a day to complete with a slight overtime. Of course, this is an ideal situation where actual construction may take more time, so we can extend it by 3 days; However, if traditional manual road marking machines want to complete the 100 kilometer marking project within 3 days, even with 5 manual road marking machines working at full power and overtime, they may not be able to complete it. Moreover, if it rains during the construction period of the road marking machine, as long as the rain does not stop, the construction period will be indefinitely extended. Especially during the rainy season in the south, such situations are particularly frequent. And the driving type road marking machine can seize the rare good weather during this season and complete the construction in a shorter time. As long as the marking construction is completed when the pavement is dry, the impact of rainstorm on the marking quality is minimal. With the increasing cost of labor in China, the benefits of a ride road marking machine will become increasingly apparent. Using it every day for marking is equivalent to saving oneself 5-6 workers for 3 days of expenses.

In addition to the ride road marking machine, there is also a more efficient road marking equipment, which is the road marking truck. The disadvantage of a ride type road marking machine is that the equipment is relatively large and not very convenient to transport. If the construction team receives cross provincial line marking construction business, hauling a passenger driving road marking machine is a relatively troublesome task. So, in order to overcome this drawback, a brand new large-scale road marking equipment - road marking truck was born.

Introduction to Road Marking Machine

Road marking machine is a road construction machine widely used in roads, highways, parking lots, squares, and runways to mark different restrictions, guidelines, and warning rules on flat ground. The Road marking machine has played a huge role in urban planning and highway construction due to its advantages of speed, efficiency, and accuracy, maximizing the savings in road construction time and economic investment.

Accessories for road marking machine

1. Marking width: The internationally recognized road marking width is 15 centimeters. Considering that the marking machine may be used in parking lots, residential areas, and other areas, it is recommended to purchase a marking machine with width adjustment function, which will help to use it reasonably and save paint. The adjustable range is generally 5-15 centimeters.

2. Paint types: There are two commonly used types of paints: solvent based and water-soluble. If the marking machine does not "pick 3, pick 4" and both can be used, it can expand your business scope to sports fields, lawns, and other places.

3. Hand held spray gun: Using a hand held spray gun not only allows you to freely use templates to spray various symbols, but also allows you to work on walls, columns, and other places outside the ground. The handheld spray gun has gradually become the standard configuration for various marking machines.

4. Cleaning system: Some road marking machines are equipped with an automatic cleaning system, which can quickly clean the pipeline system after each completion, saving more than half of your cleaning time.

5. Glass bead system: Road maintenance companies also need to consider configuring a glass bead distribution system as a standard configuration. This system can spray glass microspheres to fully meet national requirements for marking construction.

6. Bend operations. Some road marking machines also have an extra wheel installed at the rear, which allows you to freely construct along curved markings. Companies engaged in sports fields and multi bend operations can consider purchasing a marking machine with this function. Some already have this feature on their own.

The structure of the road marking machine

The structure of the road marking machine is diverse, and there may be differences in structure due to different production design situations or application to different construction objects and different raw materials. The marking machine generally needs to have devices such as an engine, air compressor, paint (melt) bucket, marking bucket (spray gun), guide rod, controller, etc., and is equipped with various auxiliary drive carriers according to needs.

Engine: Most road marking machines use an engine as the power source, and some also use batteries as the power source. If an engine is used, its power ranges from approximately 2, 5 HP to 20 HP, but it is best to use internationally renowned brands such as Briggs&Stratton in the United States and Honda in Japan. Its advantages are self-evident: stable performance and easy procurement of spare parts, which almost determines the operational performance of the entire equipment; If using batteries as power, it is also recommended to consider the running time for each charge, preferably no less than 7 hours (approximately 1 day of working time).

Air compressor: For road marking machines that rely on air for spraying (rather than hydraulic spraying), it is also the main component that affects the overall performance of the machine. Like engine 1, you should consider purchasing products equipped with internationally renowned brand air compressors. The larger the emission, the better, but with a certain limit.

Material bucket: It mainly has two functions: one is to hold paint, in this sense, the size of its capacity will affect the number of refills and the progress of the operation. Another function that many users overlook is that the container is still a pressure vessel, which is pressurized by an air compressor to become a pressurized "gas tank" and become the driving force for marking work. In this sense, its sealing, safety, and corrosion resistance should be considered by users. Good buckets are all made of stainless steel, and some products even meet the American ASME standard.

Spray gun: One type is to use a "spray box" for spraying, which is relatively cheap and especially suitable for sports field lawns and general parking lot construction; Another method is to use a spray gun for spraying, which is strictly a spray gun, but the price of its nozzle is relatively high.

Classification of road marking machines

According to the device carrier

Vehicle mounted road marking machine: In the form of a driving mount, the front and rear mechanical devices of the vehicle body are used for large-scale engineering and long-distance construction scribing. The operator needs to understand driving skills, drive walking, and save time and effort.

Truck mounted road marking machine

Self Propelled road marking machine: In the form of a handheld drive, the machine itself has a driving device, which allows for self-propelled walking without the need for manual assistance. It is suitable for short distance construction in large and medium-sized projects and in vehicles with inconvenient operation, and is flexible and easy to operate.

Hand push type road marking machine: In the form of hand assistance, the manual pushing roller slide device requires the use of human labor for walking. It is suitable for small projects and short distance construction, with convenient activities and flexible operation.

According to construction temperature

Hot melt road marking machine: It is a highly automatic machine that has gradually developed and improved with the development of hot melt coatings. Construction requires a set of several equipment to complete various construction functions from melting to marking. This set of equipment generally consists of a hot melt kettle, a road marking machine (including a zebra crossing marking machine), a pre marking machine, and a coating machine. Of course, users can choose different models, grades, and functions of equipment configurations based on their own economic strength, engineering quantity, and degree of specialization. The hot melt marking machine in the configuration can be divided into three types based on its marking method: hot melt scraping type, hot melt extrusion type, and hot melt spraying type.

Cold spray (cold paint) road marking machine: Cold spray marking is one of the oldest conventional marking machines, and this type of marking is usually completed by a room temperature road marking machine. Cold spray road marking machines can be divided into two types according to their marking methods: high-pressure airless type and low-pressure air assisted type; According to the types of coatings used, it can be divided into three types: ambient temperature flux type, ambient temperature water-based, and heating solvent type (the generalized ambient temperature road marking machine also includes dual component type, especially the dual component spraying type, which is a broad-spectrum road marking machine that combines the functions of conventional ambient temperature coatings and dual component coatings spraying).

Two component road marking machine: Two component road marking is a high-end marking method that has emerged in recent years. Unlike hot melt marking and room temperature marking, which form coatings by physical drying methods such as temperature drop or solvent (water-based) evaporation, two component road marking is a new type of marking method that forms coatings by internal chemical crosslinking. The two-component road marking machine used for construction can be divided into three types based on the type of coating it is suitable for and the appearance of the applied line type: the throwing coating structure type, the scraping flat line type, and the high-pressure airless spraying type.

1. Cleaning paint: After the construction is completed, the paint inside the material barrel and hopper should be cleaned in a timely manner to avoid deformation of the hopper during subsequent construction due to high temperature heating, which may cause material leakage. At the same time, it will also waste gas and time

2. For the moving parts of the marking bucket, special protective liquid should be added before construction to make the marking bucket switch flexible. If the switch is not flexible, it can cause delayed closing and material leakage

3. Front fire path: Normally, the front fire path does not need to be opened, only when the temperature is low

4. During construction, the marking hopper must be hung up before the marking machine can be moved back. Otherwise, it may cause damage to the silicone pad inside the glass bead spreader

5. Landing knife: When the landing knife is in high temperature, it should not come into contact with water to prevent the alloy from falling off. When lifting equipment on or off the vehicle, it is necessary to prevent the landing knife from hitting the edge of the car, causing the alloy strip of the landing knife to break

6. Tires: Regularly inspect and clean the asphalt and stones on the tires to reduce tire wear

7. Discharge door: When pouring the coating from the hot melt kettle into the marking machine, check whether the discharge door is closed to prevent the coating from overflowing from the marking hopper, which may contaminate the ground and damage the marking machine rubber wheel

8. The screws on the landing knife of the marking bucket should be replaced in a timely manner to prevent rusting
