[0002] Road marking is a traffic safety facility used to guide, regulate, and warn road users. It is currently the most widely used road marking technique in my country. It consists of synthetic resin, glass beads, coloring pigments, fillers, additives, and solvents. During application, powdered paint is poured into a hot melt kettle, heated to a specified temperature, stirred, and melted. It is then applied to the road surface using specialized equipment, and after solidification, it forms distinct lines. It features fast drying, wear resistance, and good reflectivity.

[0003] During the marking process, the paint is in a flowing state. When the flowing paint is being transported, air is retained, which may cause air bubbles to form. These air bubbles can easily affect the stability of the marking process. In addition, impurities and dust on the road can also affect the marking process. Based on this, this application provides a road marking machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a road marking machine that solves the problem that in existing technologies, the paint is in a flowing state during marking, and air bubbles are easily generated during the transportation process, which affects the stability of the marking.

[0005] The road marking machine of this utility model includes a movable support assembly for moving the marking line and a material discharge assembly disposed on the movable support assembly; The mobile support assembly includes a support frame, a liquid storage tank is provided on the top of one side of the support frame, a drive motor is provided on one side of the liquid storage tank, and a roller is provided at the bottom of the support frame. The roller is adapted to the drive motor and is used to drive the mobile support assembly to move. The discharge assembly includes a temporary storage tank, and a connector is provided on the top of the temporary storage tank. The connector is connected to the liquid storage tank through a pipe for conveying the paint used for marking lines. The temporary storage box includes a box body, and a perforated plate is provided at the bottom of the box body. The perforated plate is slidably connected to one side of the bottom of the box body to facilitate the replacement of the perforated plate.

[0006] As a further improvement of this utility model, a trolley handle is provided on one side of the support frame for use with rollers to push the support frame to move.

[0007] As a further improvement of this utility model, a flow guiding cavity is provided on the inner side of the box, and a filter assembly is provided on the inner side of the flow guiding cavity to eliminate air bubbles during paint conveying.

[0008] As a further improvement of this utility model, a strip-shaped through hole is provided at the bottom of the box body, and a limiting groove is provided on both sides of the inner wall of the strip-shaped through hole, and the limiting groove is adapted to the perforated plate.

[0009] As a further improvement of this utility model, a positioning hole is provided on one side of the box body, located on the side of the strip-shaped through hole, and the inner side of the positioning hole is slidably adapted to one end of the mesh plate.

[0010] As a further improvement of this utility model, the top of the perforated plate is provided with one or more diversion holes for dripping paint, and a cover plate is installed above the diversion holes to cover them.

[0011] As a further improvement of this utility model, a sealing groove is provided on the top of the box, and the sealing groove is adapted to the sealing plate provided below the connector.

[0012] As a further improvement of this utility model, a recessed groove is provided on one side of the perforated plate, and a handle is installed in the groove.

[0014] As a further improvement of this utility model, a cleaning roller is provided at the bottom of the air chamber, and one or more air holes are provided on the outer side of the cleaning roller at equal intervals for cleaning the marked area.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a filter assembly installed inside the flow channel of the temporary storage box. When the paint is transported from the storage tank to the temporary storage box and enters the flow channel, the paint passes through the filter assembly. The multi-layer filter material of the filter assembly can adsorb and break air bubbles through tiny pores, effectively eliminating air bubbles generated during paint transport and preventing air bubbles from flowing out with the paint and affecting the stability and quality of the scribing. The perforated plate at the bottom of the chamber can perform secondary filtration of the paint, further intercepting any residual air bubbles, ensuring that the air bubble content in the final paint used for marking is significantly reduced, thus improving the stability and uniformity of the marking. The cleaning component at the front end of the discharge assembly has air holes spaced at equal intervals on the outer side of the cleaning roller at the bottom of the air chamber. Before the marking operation, the compressed air in the air chamber is sprayed out through the air holes, which can blow away the dust and impurities on the surface of the marking area, making the road surface clean and providing a good foundation for subsequent marking, reducing the impact of impurities on the marking quality. Furthermore, the perforated plate not only filters air bubbles but also intercepts impurities in the paint, preventing them from entering the marking area and ensuring the clarity and quality of the markings. The perforated plate is also connected to the bottom of the housing via a sliding plug-in connection, making it easy to replace and maintaining a consistently good filtration effect.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 When marking lines, the paint is in a flowing state. During the transportation process, the air trapped in the moving air can easily generate air bubbles. These air bubbles can affect the stability of the marking. Impurities and dust on the road during the marking process can also have a certain impact on the marking. Based on this, this application provides a road marking machine, including a moving support component 1 for moving the marking and a material discharge component 2 set on the moving support component 1. The mobile support assembly 1 includes a support frame 13, a liquid storage tank 12 is provided on the top of one side of the support frame 13, a drive motor 14 is provided on one side of the liquid storage tank 12, and a roller 15 is provided at the bottom of the support frame 13. The roller 15 is adapted to the drive motor 14 and is used to drive the mobile support assembly 1 to move. The discharge assembly 2 includes a temporary storage box 22, and a connector 21 is provided on the top of the temporary storage box 22. The connector 21 is connected to the liquid storage box 12 through a pipe for conveying the paint for marking lines. The temporary storage box 22 includes a box body 221. A perforated plate 224 is provided at the bottom of the box body 221. The perforated plate 224 is slidably connected to one side of the bottom of the box body 221, which facilitates the replacement of the perforated plate 224.

[0021] The support frame 13 is made of high-strength metal materials, such as steel, and has sufficient strength and stability to bear the weight of components such as the liquid storage tank 12, drive motor 14 and discharge assembly 2, while maintaining balance during movement.

[0022] The liquid storage tank 12 is located on the top side of the support frame 13. It is a container used to store the paint required for marking lines. Generally, corrosion-resistant materials, such as stainless steel, are selected to prevent the paint from corroding the tank body 221. For easy filling, an openable top cover can be provided on the top of the liquid storage tank 12 to facilitate the addition of paint and to prevent impurities from entering the tank when adding paint.

[0023] The drive motor 14 is installed on one side of the liquid storage tank 12 and is connected to the roller 15 through a transmission device, which can be a chain drive or a belt drive. The drive motor 14 has an adjustable speed, and the construction personnel can adjust the speed of the drive motor 14 according to different marking requirements, such as the width and speed of the marking, thereby controlling the moving speed of the moving support assembly 1.

[0024] Rollers 15 are located at the bottom of the support frame 13 and are adapted to the drive motor 14. There are usually four or more rollers to ensure the stability of the support. When the drive motor 14 starts, it drives the rollers 15 to rotate through the transmission device, thereby moving the entire movable support assembly 1 to realize the mobile operation of road marking.

[0025] The storage box 22 has a sealed container 221 for temporarily storing paint transferred from the liquid storage tank 12. The material of the container 221 is the same as that of the liquid storage tank 12. The top of the temporary storage box 22 is equipped with a connector 21, which is connected to the liquid storage box 12 through a pipe to ensure that the paint can be smoothly transported from the liquid storage box 12 to the temporary storage box 22. In order to facilitate the adjustment of the feeding rate, a valve can be installed on the pipe to control the flow rate of the paint. The construction personnel can adjust the opening of the valve according to the actual marking situation to control the amount of paint conveyed.

[0026] A perforated plate 224 is provided at the bottom of the housing 221, and the perforated plate 224 is slidably connected to one side of the bottom of the housing 221. The function of the perforated plate 224 is to filter the paint, preventing impurities and possible air bubbles in the paint from entering the scribing area, thereby improving the quality of the scribing. When it is necessary to change to different hole diameters and marking ranges, the construction personnel can easily pull out the old perforated plate 224 and replace it with a new perforated plate 224 by sliding and plugging it in, without complicated tools and operations, which improves the convenience of maintenance.

[0027] When performing road marking operations, paint is first added to the storage tank 12. Then, the drive motor 14 is started, which drives the roller 15 to rotate through the transmission device, causing the movable support assembly 1 to move. Simultaneously, the valve on the pipe connecting the storage tank 12 and the temporary storage tank 22 is opened, allowing paint to be transported from the storage tank 12 to the temporary storage tank 22. In the temporary storage tank 22, the paint is filtered through the perforated plate 224 to remove impurities and air bubbles, and then flows evenly from the bottom of the tank 221. Driven by the movable support assembly 1, clear and stable lines are formed on the road surface. During construction, the operator can adjust the speed of the drive motor 14 and the opening of the pipe valve according to the actual situation to meet different marking requirements. When the perforated plate 224 needs to be replaced, the paint supply is stopped, the old perforated plate 224 is removed, and a new perforated plate 224 is inserted to continue the marking operation.

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A trolley handle 11 is provided on one side of the support frame 13, which is used to move the support frame 13 in conjunction with the rollers 15.

[0029] The inner side of the housing 221 is provided with a flow guide cavity 223, and the inner side of the flow guide cavity 223 is provided with a filter assembly to eliminate air bubbles during paint conveying.

[0030] The bottom of the box 221 is provided with a strip-shaped through hole, and the inner walls of the strip-shaped through hole are provided with limiting grooves 227 on both sides, which are adapted to the mesh plate 224.

[0031] A positioning hole 226 is provided on one side of the housing 221, located on the side of the strip-shaped through hole. The inner side of the positioning hole 226 is slidably adapted to one end of the mesh plate 224.

[0032] A flow guide cavity 223 is provided on the inner side of the housing 221 to allow the paint to be distributed more evenly on the bottom of the housing 221, preparing it for subsequent marking operations. The inner wall of the flow guide cavity 223 is smooth and made of a material that does not chemically react with the paint, such as plastic or stainless steel, to ensure that the paint is not contaminated during the flow process.

[0033] A filter assembly is installed inside the flow channel 223. This assembly is primarily used to eliminate air bubbles generated during paint delivery. The filter assembly consists of multiple layers of filter material, such as a filter screen with micropores. When the paint is transported from the storage tank 12 to the temporary storage tank 22 and then enters the flow channel 223, it passes through the filter assembly. As air bubbles pass through the micropores of the filter material, they are adsorbed and broken by the surface tension, thus eliminating the bubbles. This effectively prevents air bubbles from flowing out of the tank 221 with the paint, affecting the stability and quality of the road markings.

[0034] A strip-shaped through-hole is provided at the bottom of the housing 221. This through-hole is the channel through which paint flows out of the housing 221 and forms markings on the road surface. Limiting grooves 227 are provided on both sides of the inner wall of the strip-shaped through-hole. The limiting grooves 227 are adapted to the perforated plate 224. The function of the limiting grooves 227 is to position and fix the perforated plate 224, ensuring that the perforated plate 224 is accurately installed at the bottom of the housing 221 and will not shift under conditions such as paint flow and vehicle vibration.

[0035] A positioning hole 226 is provided on one side of the housing 221, near the strip-shaped through hole. The inner side of the positioning hole 226 is slidably fitted to one end of the perforated plate 224. When the perforated plate 224 needs to be installed, the operator can align one end of the perforated plate 224 with the positioning hole 226 and then push the perforated plate 224 into the bottom of the housing 221 along the limiting groove 227. The function of the positioning hole 226 is to provide accurate positioning for the installation of the perforated plate 224, ensuring that the perforated plate 224 can be correctly installed at the bottom of the housing 221 and aligned with the strip-shaped through hole, ensuring that the paint can flow out smoothly through the perforated plate 224. At the same time, the positioning hole 226 can also prevent the perforated plate 224 from tilting or shifting during installation, improving the accuracy and efficiency of installation.

[0036] During road marking operations, operators can choose to use the drive motor 14 to move the moving support assembly 1, or, in special circumstances, manually push the trolley by holding the handle 11. After the paint is transferred from the storage tank 12 to the temporary storage tank 22, it first enters the guide chamber 223, where it passes through a filter assembly to eliminate air bubbles. Then, the paint passes through the perforated plate 224 for further filtration of impurities, flowing out through the strip-shaped holes to form lines on the road surface. When the perforated plate 224 needs to be replaced, the operator can pull it out from the positioning hole 226 and the limiting groove 227, replace it with a new one, and continue the marking operation. Throughout the process, all components cooperate to ensure the smooth operation of the road marking work and improve the quality and stability of the marking.

[0037] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 as well as Figure 9 The top of the perforated plate 224 is provided with one or more diversion holes 225 for dripping paint, and a cover plate is installed above the diversion holes 225 to cover the diversion holes 225.

[0038] The top of the housing 221 is provided with a sealing groove 222, which is adapted to the sealing plate provided below the connector 21.

[0039] A recessed groove is provided on one side of the perforated plate 224, and a handle 228 is installed in the groove.

[0040] The top of the perforated plate 224 is provided with one or more diversion holes 225. The function of these diversion holes 225 is to allow the paint to drip more evenly. After the paint enters the box 221 from the temporary storage box 22 through the connector 21 and the pipe, it will fall onto the perforated plate 224. The diversion holes 225 can disperse the paint and prevent it from concentrating in one place, thus making the marking more even. A cover plate is installed above the diversion holes 225. The cover plate can shield the diversion holes 225. When the marking work is not required, the cover plate can prevent dust, debris, etc. from entering the diversion holes 225, avoiding blockage and ensuring that the paint can pass through the diversion holes 225 normally in subsequent operations. The cover plate can be installed on the perforated plate 224 by simple snap-fit ​​or sliding connection, which is convenient to open and close.

[0041] A recessed groove is provided on one side of the perforated plate 224, and a handle 228 is installed in the groove. The handle 228 facilitates the replacement of the perforated plate 224 by the operator. Since the perforated plate 224 needs to be replaced regularly to ensure the filtration effect and the quality of the marking, the handle 228 allows the operator to easily pull out or insert the perforated plate 224 from the limiting groove 227 and positioning hole 226 at the bottom of the housing 221 by holding the handle 228, without directly contacting the surface of the perforated plate 224, thus avoiding paint getting on their hands and improving the efficiency of replacing the perforated plate 224.

[0042] A sealing groove 222 is provided on the top of the housing 221, which is adapted to the sealing plate provided below the connector 21. When the connector 21 is connected to the liquid storage tank 12 through a pipe, the sealing plate will be embedded in the sealing groove 222, which can prevent the paint from leaking out from the connection between the connector 21 and the housing 221 during the transportation process, ensuring the sealing and safety of the paint transportation. The sealing plate can be made of materials with good sealing performance such as rubber.

[0043] Example 2: Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The front end of the discharge assembly 2 is provided with a cleaning assembly 3, which includes an air chamber 32. The outer side of the air chamber 32 is adapted to the inner side of the support frame 13.

[0044] A cleaning roller 31 is provided at the bottom of the air chamber 32. One or more air holes are provided on the outer side of the cleaning roller 31 at equal intervals for cleaning the marked area.

[0045] The front end of the discharge assembly 2 is provided with a cleaning assembly 3. The cleaning assembly 3 includes an air chamber 32. The outer side of the air chamber 32 is adapted to the inner side of the support frame 13. The air chamber 32 is a component for storing compressed air. It can be connected to an external air compressor through a pipe to continuously replenish compressed air. A cleaning roller 31 is provided at the bottom of the air chamber 32. One or more air holes are provided on the outer side of the cleaning roller 31 at equal intervals. Before the road marking operation, the cleaning component 3 will clean the marking area. When the air chamber 32 is filled with compressed air, the compressed air will be ejected through the air holes to form an airflow. The airflow can blow away the dust, impurities and other debris on the surface of the marking area, making the road surface cleaner and providing a foundation for subsequent marking operations. The cleaning roller 31 can move together with the moving support component 1 and continuously clean the road surface during the movement to ensure the cleaning effect of the marking area.

[0046] During road marking operations, operators first check that the sealing plate is correctly embedded in the sealing groove 222 to ensure the sealing of the paint delivery. Then, the cover plate is opened or closed as needed to prepare for paint delivery. The air compressor is started, filling the air chamber 32 with compressed air. As the moving support assembly 1 moves, the cleaning assembly 3 first cleans the marking area. Compressed air is ejected through the air holes on the cleaning roller 31, blowing away dust and impurities from the road surface. Then, the paint enters the temporary storage tank 22 from the storage tank 12 through the connector 21 and pipe. After being filtered and diverted by the guide chamber 223, the filter assembly, and the perforated plate 224, it flows out through the strip-shaped holes, forming uniform lines on the cleaned road surface. When the perforated plate 224 needs to be replaced, the operator holds the handle 228 to pull out and replace it. Throughout the process, all components work together to ensure the quality and efficiency of road marking.
