Description

Technical Field

[0001] This invention relates to the field of road technology, and in particular to a curbstone film applicator. Background Technology

[0002] In road construction, the application of asphalt tack coat is a crucial step. However, asphalt easily contaminates the surface of curb stones during this process, posing a significant challenge. Once contaminated, asphalt, due to its unique properties, adheres firmly to the curb stone surface, making effective cleaning virtually impossible. This results in compromised aesthetics and increased maintenance costs. Therefore, inventing a specialized tape-applying machine for curb stones, capable of quickly and precisely applying tape to the upper and side surfaces before the asphalt tack coat is applied, forms a reliable protective barrier, ensuring the curb stone surface remains uncontaminated by asphalt during construction. This would greatly improve the current state of curb stone protection in road construction. Summary of the Invention

[0025] Among them, connector 27 and connector 29 are both detachable latches; the inclined profile 24, reinforcing profile 25, transverse profile 26, longitudinal profile 28 and longitudinal profile 210 are all aluminum profiles.

[0026] like Figure 6 As shown, the top film-bearing roller 1, the side tearing paper roller 9, and the side film-bearing roller 14 all have the same structure as the top tearing paper roller 7. The specific structure of the top tearing paper roller 7 includes a fixed shaft 71, a first fixed disk 72, a connecting guide post 73, a clamping plate 74, an inclined guide strip 75, a screw 76, an inclined guide groove 77, a second fixed disk 78, a rotating head 79, and a circular slider 710. The fixed shaft 71 is fixedly connected to the swing arm 5 on one side, and the first fixed disk 72 is movably connected to the center of the fixed shaft 71. There are several connecting guide posts 73, with one end of each post evenly fixed to the side of the first fixed disk 72, and the other end of each post fixedly fixed to the inside of the second fixed disk 78. The screw 76 is externally and movably connected to the center of the fixed shaft 71 on one side, and externally and movably connected to the center of the second fixed disk 78 on the other side. A rotating head 79 is provided at the end of the other side of the screw 76. Several guide holes are provided around the circular slider 710 and are movably connected to the outside of the corresponding connecting guide post 73. The threaded hole in the center of the circular slider 710 is connected to the screw 76. Several inclined guide grooves 77 are opened on the outer surface of the circular slider 710. There are several clamping plates 74, and the clamping plates 74 are all located between the first fixed disk 72 and the second fixed disk 78. Inclined guide bars 75 are fixedly connected to the inner side of the clamping plates 74, and the outside of the inclined guide bars 75 are movably connected to the inside of the corresponding inclined guide grooves 77.

[0027] The card plate 74 has two sides parallel to the inner sides of the first fixed plate 72 and the second fixed plate 78; the inclined guide groove 77 is a T-shaped inclined guide groove; the inner sides of the outer cylindrical surfaces of the top soft plastic roller 8, the side soft plastic roller 11, the side soft plastic roller 13 and the top soft plastic roller 17 are all provided with inner chamfers, and the inner chamfers match the chamfers of the curb stones.

[0028] The invention is used as follows: The invention has a reasonable and simple structure, low production cost, and convenient installation. In use, firstly, the entire roll of wallpaper is fixed to the top film-supporting roller 1. For side film application, the corresponding wallpaper is fixed to the side film-supporting roller 14. Specifically, during installation, the entire roll of wallpaper is first fitted inside the top film-supporting roller 1 and the side film-supporting roller 14, and the wallpaper roll for collecting torn paper is fitted onto the top tear paper roller 7 and the side tear paper roller 9. The working principle of the top tear paper roller 7 is explained here: rotating the rotating head 79 drives the screw 76 to rotate. When the screw 76 rotates, due to its threaded connection with the circular slider 710, the circular slider 710 moves along the connecting guide post 73. As the circular slider 710 moves, the inclined guide groove... 77 interacts with the inclined guide strip 75. Because the inclined guide groove 77 is a T-shaped inclined guide groove, this special structure allows the clamping plate 74 to move radially between the first fixed plate 72 and the second fixed plate 78. When the rotating head 79 rotates in the forward direction, the clamping plate 74 will gradually move outward to tighten the inner wall of the wallpaper tube to complete the installation and fixation. Then, the inner film of the wallpaper is torn off and pulled out to a certain length, and it is fixed on the top surface tearing paper roller 7 (top surface film application case) and the side surface tearing paper roller 9 (side surface film application case). At this time, it is important to ensure that the adhesive side of the wallpaper is facing outward. When applying the top surface film, hold the handle 21 of the machine and move the machine to the starting position of the curbstone, so that the top surface soft plastic roller 18 and the top surface soft plastic roller 217 are located on the top surface of the curbstone, while the clamping roller 18 clamps the inner wall of the curbstone. With the surface (roller 18 able to rotate freely), gently apply the adhesive wallpaper to the top surface of the curbstone. Due to the tension of the tension spring 6, the swing arm 5 drives the top surface tearing roller 7 to press firmly against the top surface of the curbstone. At the same time, the top surface soft plastic rollers 18 and 2 also firmly hold the top surface of the curbstone. Manually grasp the handle 21 and push the machine forward. The top surface tearing roller 7 rolls on the top surface of the curbstone. As the machine moves, under the action of the tension spring 6, the top surface tearing roller 7 continuously performs tearing motions. Simultaneously, the wallpaper is flatly pressed against the top surface of the curbstone by the action of the top surface soft plastic rollers 18 and 2 17. Moreover, the inner chamfer of the soft plastic roller (radius of 1cm, the same as the chamfer radius of the curbstone) can press the wallpaper well against the surface. The wallpaper is applied to the chamfered edge of the curbstone. The machine is continuously pushed forward until the wallpaper is completely applied to the top surface of the curbstone. Simultaneously, the side-side wallpapering process is similar to the top-side application. The relevant side-side components of the machine are aligned with the curbstone side, ensuring that side soft plastic rollers 11 and 213 are positioned on the curbstone side. The wallpaper on the side-side wallpapering roller 14 is ready to be applied to the side. The tension spring 210 causes the swing arm 212 to drive the side-side paper-tearing roller 9 to firmly press against the curbstone side. Side soft plastic rollers 11 and 213 hold the curbstone side, and the machine is pushed forward. The side-side paper-tearing roller 9 rolls and tears the wallpaper, while the side soft plastic rollers 11 and 213 flatten the wallpaper onto the curbstone side.The side facade film application operation is completed. Throughout the process, the length of frame 2 is 1.0m (adjustable range 0.5-1.5m). The diameter of the top film-bearing roller 1 varies from 5-10cm (length 15cm), the diameter of the top paper-tearing roller 7 varies from 5-10cm (length 15cm), and the diameter of the soft plastic rollers (including top soft plastic roller 18, side soft plastic roller 11, side soft plastic roller 213, and top soft plastic roller 217) is 8cm (length 15cm). Tension springs ensure sufficient tension to keep the rollers (top paper-tearing roller 7 and side paper-tearing roller 9) firmly attached to the curb surface. Movable pins (movable pin 13 and movable pin 215) ensure the lever arm connecting the rollers can move. Removable latches such as connector 127 and connector 229 can be freely disassembled as needed to facilitate adjustment or maintenance of relevant components of frame 2.
