[0002] Car film is a new, high-performance, environmentally friendly film widely used in the automotive detailing and maintenance industry. It's primarily made from TPU film, which is produced using specialized processes such as calendaring, casting, film blowing, and coating. Currently, after extruding the TPU base film, a film laminator is used to laminate protective films on both sides.

[0003] Protective film is supplied in rolls, and foreign matter may become attached to it during production, storage, and transportation. On automotive film production lines, after unwinding, the protective film passes over conveyor rollers. Therefore, foreign matter on the protective film can easily transfer to the conveyor rollers. If not removed promptly, dust and foreign matter on the conveyor rollers can easily transfer back onto the protective film. Therefore, the conveyor rollers must be cleaned promptly. Currently, the conveyor rollers are primarily cleaned of foreign matter by scraping after the machine is shut down. However, automotive film production lines operate continuously, and downtime not only results in significant losses, but restarting requires re-adjustment to meet the requirements of online automotive film production. Furthermore, different film types have varying widths, corresponding to different conveyor roller lengths.

[0004] Therefore, how to design a surface dust removal device that can remove foreign matter on the conveyor roller without stopping the machine and is applicable to conveyor rollers of different lengths has become a technical problem that needs to be solved urgently in this field. Utility Model Content

DETAILED DESCRIPTION

[0029] To deepen the understanding of the present invention, the present invention will be further described below in conjunction with implementation examples and accompanying drawings. The present invention can be implemented in the following ways:

[0030] Reference Figure 1-4 , a conveyor roller surface dust removal device for a car film production line includes a frame 1, a dust collector 2, a guide rail 3 and a sliding drive 4.

[0031] The frame 1 is provided with a conveying roller 5 for conveying the film, and the conveying roller 5 is rotatably connected to the frame 1 via a bearing. When the film is conveyed, the conveying roller 5 rotates.

[0032] The dust collector 2 includes an adhesive roller 21 and a lift drive 22 that drives the adhesive roller 21 upward and downward toward the conveyor roller 5. The lift drive 22 includes a bracket 221 and a cylinder 222 that controls the bracket 221's elevation. The movable ends of the adhesive roller 21 are movably mounted on the bracket 221. The dust collector 2's wiring is mounted on the frame 1 via a drag chain 6. As the bracket 221, controlled by the cylinder 222, raises the adhesive roller 21, it stops rising when it contacts the surface of the conveyor roller 5, allowing the adhesive roller 21 to absorb foreign matter from the conveyor roller 5.

[0033] To facilitate replacement of the adhesive roller 21, the two ends of the adhesive roller 21 are detachably and rotatably connected to the bracket 221. Specifically, the bracket 221 includes a base plate 2211 and connectors 2212 detachably disposed at both ends of the base plate 2211. The base plate 2211 is fixedly connected to the push rod 2221 of the cylinder 222. The cylinder 222 controls the raising and lowering of the push rod 2221, which in turn drives the base plate 2211 up and down. The adhesive roller 21 is detachably and rotatably connected to the connectors 2212. In this embodiment, the bottom of the connector 2212 is detachably connected to the two ends of the base plate 2211 via screws. The connector 2212 has a positioning ridge 2213 extending outwardly from the side facing the base plate 2211. The two ends of the base plate 2211 are concave to form positioning grooves 2214 that adapt to the positioning ridge 2213. The design of the positioning ridges 2213 and the positioning grooves 2214 enables the connector 2212 to be quickly and accurately installed on the base plate 2211 .

[0034] To drive the dust collector 2 to reciprocate along the conveyor rollers, the guide rails 3 are positioned to the sides of, and parallel to, the conveyor rollers 5. The ends of the guide rails 3 extend beyond the ends of the conveyor rollers 5. In other words, the guide rails 3 must be longer than the conveyor rollers 5 to allow the dust collector 2 to remove foreign matter from the conveyor rollers 5. Guide rail support brackets 31 are provided at the bottom ends of the guide rails 3 to mount them on the frame 1.

[0035] The sliding drive 4 includes a sliding block 41 arranged at the bottom of the dust collector 2 and a driving source 42 that drives the sliding block 41 to move back and forth in the direction of the guide rail 3. The driving source 42 described in this embodiment is a motor. The sliding block 41 is movably mounted on the guide rail 3, and the bottom of the sliding block 41 is movably connected to the driving source 42 through a screw. The screw is a component that converts rotary motion into linear motion. Its principle is common knowledge and will not be elaborated here. When the driving source 42 drives the sliding block 41 to move back and forth along the guide rail 3, it also drives the dust collector 2 to move back and forth in the direction of the guide rail 3. The lifting drive 22 and the driving source 42 of this embodiment are both electrically connected to the central controller of the automobile film production line, that is, the operation of the lifting drive 22 and the driving source 42 can be controlled by the central controller of the automobile film production line.

[0036] To limit the reciprocating travel of the dust collector 2 and adapt it to conveyor rollers 5 of varying lengths, movable positioners 32 are provided at both ends of the guide rail 3. Positioning blocks 411, which adapt to the movable positioners 32, are provided on the sides of the slider 41. A guide groove 33 is provided at the end of the guide rail 3 where the movable positioner 32 resides. Positioner sliders 321, which slide within the guide groove 33, are provided on either side of the movable positioner 32. The positioner sliders 321 are movably mounted on the guide groove 33 via screws and nuts, allowing the movable positioner 32 to slide within the guide groove 33. A U-shaped notch 322 is provided at the top of the movable positioner 32, through which the positioning block 411 passes. The distance between the two movable positioners 32 is the travel of the slider 41. When the positioning block 411 on the slider 41 passes through the U-shaped notch 322 on the slider 41, the slider 41 stops moving, preventing the slider 41 from colliding with the end of the guide rail 3.

[0037] Working Principle: When adjusting the machine, the distance between the two movable positioners 32 is pre-adjusted according to the length of the conveyor roller 5. When a worker finds foreign matter on the conveyor roller 5, they can activate the drive source 42 of the sliding actuator 4 through the central controller of the automotive film production line. The drive source 42 drives the sliding block 41, which drives the dust collector 2 along the guide rail 3 to the position corresponding to the foreign matter. Then, the lifting drive 22 drives the adhesive roller 21 to rise to the surface of the transmission roller. Since the transmission roller 5 is in a rotating state, the transmission roller 5 will drive the adhesive roller 21 to rotate. The circumferential side of the adhesive roller 21 is all sticky. It can use its own viscosity to adhere to the foreign matter on the surface of the conveyor roller 5. After the foreign matter is removed, the lifting drive 22 controls the adhesive roller 21 to descend.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
