Description

Technical Field

[0001] The utility model relates to the technical field of road marking spraying equipment, in particular to a structural road marking forming device. Background Art

[0002] Road markings convey sensory visual information to road users through shapes, colors, and vibrations, and are reasonably set in combination with traffic roads and environmental conditions. They guide and manage drivers' driving behaviors to ensure smooth traffic and driving safety. They must ensure all-weather visibility, especially at night, in bad weather, and other conditions with poor visibility. At the same time, road markings are called "activity guides" that can help vehicle drivers better understand road traffic conditions, drive carefully on congested roads, and effectively reduce the probability of road traffic accidents.

[0003] Among them, the structural markings have a gentle vibration feeling after being rolled over by vehicles, and are more reflective and non-slip. They are particularly suitable for municipal roads, highways, and especially for roads in tunnels. The structural markings mainly include two-component markings and hot-melt markings. The two-component structural markings are to install a mace horizontally below the hopper gate. The mace can rotate axially under the drive of the motor. When the paint flows through the hopper gate onto the mace, it is thrown out by the rotating mace, that is, the structural marking is formed by throwing. However, the density of the marking coating is poor directly through throwing and mace extrusion, resulting in low wear resistance of the formed markings. Utility Model Content

[0004] Aiming at the technical problem that the density of the marking film after the existing two-component marking is poor after being thrown and coated, the utility model provides a structural road marking forming device, which improves the mechanical strength of the marking film by extruding the two-component raw materials, thereby ensuring that the marking has sufficient wear resistance.

[0008] Among them, due to the high viscosity of the marking material, there is a large damping when it passes through the damping discharge slit, which makes the pressure of the material discharge larger, and the spiral feeding rod can output sufficient pressure, so that the material layer output from the damping discharge slit has sufficient density. Therefore, compared with the existing method of coating by mace, the utility model can improve the mechanical strength of the marking film and ensure that the marking has sufficient wear resistance.

[0009] In an optional embodiment, an openable and closable feed port is provided at the upper end of the raw material storage tank to facilitate adding the two-component marking raw material into the raw material storage tank.

[0011] In an optional embodiment, the stirring paddle is transmission-connected to the screw feeding rod, so that the stirring paddle and the screw feeding rod can be driven to rotate simultaneously by a single driving motor, thereby simplifying the structure of the molding device.

[0012] In an optional embodiment, a material gate is provided at the lower end of the raw material storage tank, and the material gate can rotate along its own axis to switch the connection between the extrusion molding cylinder and the raw material storage cylinder by rotating the material gate, and the lower end of the stirring paddle and the upper end of the spiral feeding rod are both rotatably connected to the material gate.

[0015] In an optional embodiment, the surface of the forming extrusion roller is provided with teeth, which can, on the one hand, form a protrusion on the marking line to improve the vibration of the structural road marking line, and on the other hand, can improve the bonding force between the raw material film layers.

[0016] In an optional embodiment, the forming squeeze roller is equipped with a polarizer to drive the forming squeeze roller to vibrate the raw material film through a deflector, thereby further improving the bonding force between the raw material film layers and the bonding force between the raw material film and the ground.

[0017] In an optional embodiment, the width of the damping discharge slit is 1-1.5 mm to ensure that the two-component marking material can be extruded under a set back pressure.

[0029] Example

[0030] Combination Figure 1 and Figure 2 The present embodiment provides a structural road marking forming device, comprising: a traveling vehicle body 10, wherein the traveling vehicle body 10 is provided with a traveling wheel 11; a raw material storage tank 20, wherein the raw material storage tank 20 is arranged on the traveling vehicle body 10, and the raw material storage tank 20 is used to store a two-component marking raw material; an extrusion forming cylinder 30, wherein the upper end of the extrusion forming cylinder 30 is connected with the raw material storage tank 20, and the lower end is provided with a plurality of damping discharge slits 31, wherein the plurality of damping discharge slits 31 extend along the width direction of the traveling vehicle body 10, and a spiral feeding rod 32 is adapted in the extrusion forming cylinder 30, wherein the spiral feeding rod 32 can extrude the raw material in the raw material storage tank 20 from the damping discharge slit 31; and a forming extrusion roller 40, wherein the forming extrusion roller 40 is arranged below the traveling vehicle body 10; wherein the discharge end of the extrusion forming cylinder 30 is located between the traveling wheel 11 and the forming extrusion roller 40, so that the multi-layer raw material film outputted from the extrusion forming cylinder 30 is pressed on the ground through the forming extrusion roller 40.

[0031] It should be noted that the existing two-component road marking paint (two-component road marking raw material) is a solvent-free two-component cold plastic coating, which is mixed during use. The main raw material is acrylic resin prepolymer, and it does not contain solvent, meets environmental protection requirements, and has a high solid content (more than 99%). At the same time, in order to improve the reflective performance of the marking, glass microspheres are added to the two-component road marking raw material. The diameter of the added glass microspheres is usually 40-60 microns. Therefore, by setting the pressure extrusion, the two-component road marking raw material can be extruded into a film.

[0032] It is understandable that the upper end of the raw material storage tank 20 is provided with an openable and closable feed port 21 to facilitate adding the two-component marking raw material into the raw material storage tank 20 .

[0033] It should be understood that the raw material storage tank 20 provided in this embodiment is adapted with a stirring paddle 22 to facilitate direct stirring of the two-component marking raw material in the original storage tank before construction, and also to stir the raw material during construction to ensure the uniformity of the two-component marking raw material.

[0034] In this embodiment, the stirring paddle 22 is transmission-connected to the spiral feed rod 32 , so that the stirring paddle 22 and the spiral feed rod 32 can be driven to rotate simultaneously by a single drive motor, thereby simplifying the structure of the molding device.

[0035] Among them, a material gate plate 23 is provided at the lower end of the raw material storage tank 20, and the material gate plate 23 can rotate along its own axis to switch the connection between the extrusion molding cylinder 30 and the raw material storage cylinder by rotating the material gate plate 23, and the lower end of the stirring paddle 22 and the upper end of the spiral feeding rod 32 are both rotatably connected to the material gate plate 23.

[0036] Combination Figure 2 Specifically, the extrusion forming cylinder 30 is provided with a discharge head 33 , and the discharge head 33 is a hollow square structure. A plurality of partitions 34 are arranged inside the discharge head 33 , and the damping discharge seam 31 is a gap between two adjacent partitions 34 .

[0037] The width of the damping discharge slit 31 is 1-1.5 mm, so as to ensure that the two-component marking material can be extruded and formed under a set back pressure.

[0038] On this basis, the discharge end of the discharge head 33 is provided with a discharge nozzle 35, the cross section of which gradually decreases along the discharge direction to avoid deflection of the multi-layer raw material film cup forming extrusion roller 40 during extrusion.

[0039] Generally speaking, the surface of the forming and squeezing roller 40 is provided with teeth 41, which can form protrusions on the marking line to improve the vibration of the structural road marking line, and can also improve the bonding force between the raw material film layers.

[0040] Furthermore, the forming squeeze roller 40 is adapted to be equipped with a polarizer 42, such as an eccentric polarizer 42, so as to drive the forming squeeze roller 40 to beat the raw material film through a deflector, thereby further improving the bonding force between the raw material film layers and the bonding force between the raw material film and the ground.

[0041] In summary, the structural road marking forming device provided in this embodiment includes a traveling vehicle body 10, a raw material storage tank 20, an extrusion forming cylinder 30 and a forming extrusion roller 40. The raw material storage tank 20 is arranged on the traveling vehicle body 10, and the upper end of the extrusion forming cylinder 30 is connected to the lower end of the raw material storage tank 20, and a plurality of damping discharge slits 31 are arranged at the bottom of the extrusion forming cylinder 30, and the damping discharge slits 31 extend along the width direction of the traveling vehicle body 10. At the same time, a spiral feeding rod 32 is arranged in the extrusion forming cylinder 30, and the forming extrusion roller 40 is located on the rear side of the discharge end of the extrusion forming cylinder 30.

[0042] When in use, first close the material gate 23 to cut off the connection between the extrusion molding cylinder 30 and the raw material storage tank 20, then open the feed port 21, add the marking raw material into the raw material storage tank 20, then close the feed port 21, and start the stirring paddle 22. The raw material in the raw material storage tank 20 is stirred by the stirring paddle 22, and at the same time, the debris in the extrusion molding cylinder 30 is discharged by the rotation of the screw feeding rod to avoid affecting the composition of the initial section of the raw material layer.

[0043] After stirring for a period of time, the material gate 23 is opened to allow the stirred road marking material to enter the extrusion forming cylinder 30. By driving the spiral feeding rod 32 to rotate, the road marking material in the material storage tank 20 is extruded from the damping discharge slit 31 into layers and squeezed to the ground, and then the traveling vehicle body is driven to move. As the traveling vehicle body 10 moves, the material film is stacked on the ground and rolled by the forming extrusion roller 40, so that the multi-layer material film is pressed on the ground.

[0044] Among them, due to the high viscosity of the marking material, there is a large damping when it passes through the damping discharge slit 31, so that the pressure of the material discharge is relatively large, and the spiral feeding rod 32 can output sufficient pressure, so that the material layer output from the damping discharge slit 31 has sufficient density. Therefore, compared with the existing method of coating by mace, this embodiment can improve the mechanical strength of the marking film and ensure that the marking has sufficient wear resistance.

[0045] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
