Abstract
Description
Technical Field
[0001] This utility model relates to the field of color-changing film processing technology, specifically a color-changing film receiving and dispensing device. Background Technology
[0002] Car wrapping is a service that uses thin films in a rich variety of colors to change the appearance of a complete or partial vehicle by applying them over the entire surface. The wrap is primarily made of high-polymer materials and is easily removed. It allows for customization of the vehicle's color, paint job, or decals without damaging the original paint. Compared to full repainting, wrapping is simpler to apply, offers better protection for the vehicle's integrity, provides greater freedom in color matching, and eliminates the problem of color differences between different areas of the same color.
[0003] After the color-changing film is produced, it is wound into multiple loops and wound onto the surface of the take-up roller. In order to facilitate the processing of the color-changing film, it is generally necessary to use a take-up and unwinding device to wind and unwind the film. Existing color-changing film take-up and unwinding devices generally wind the color-changing film onto the take-up roller by rotating the take-up roller of the take-up and unwinding device. During the take-up and unwinding process, the color-changing film may sometimes develop wrinkles. In addition, a slitting device is generally set in the middle of the take-up and unwinding device. The generation of a large number of wrinkles will have a significant impact on the cutting. Utility Model Content

[0034] Working principle: In use, first, place the take-up and undo roller 6, which has multiple turns of color-changing film wound around it, above one of the second fixing blocks 503. Then, connect the first fixing block 501 above the second fixing block 503 using a snap-fit connection, thereby fixing the take-up and undo roller 6. After the take-up and undo roller 6 is fixed, place the color-changing film according to... Figure 1 The color-changing film is placed as shown. After placement, two rotary motors 8 are started. The rotation of the rotary motors 8 will cause the rotary rod to rotate, which in turn will cause the rotary take-up roller 407 to rotate, thereby moving the color-changing film on the device and realizing the take-up and take-up of the color-changing film.
[0035] The color-changing film will be properly processed on the workbench 1. After processing, the color-changing film will be wound onto the surface of the winding roller 6 at another fixed mechanism.
[0036] During operation, when wrinkles form on one side of the color-changing film on the workbench 1, the operator can activate the drive motor 411 of the take-up and take-down mechanism 4. The rotation of the drive motor 411 will cause the rotating shaft 412 to rotate, which in turn will cause the lead screw 409 to rotate. Simultaneously, the rotation of the rotating shaft 412 will cause the synchronous pulley 413 to rotate, which in turn will cause another synchronous pulley 413 to rotate via the synchronous belt 414. This will cause the lead screw 409 to rotate synchronously. The synchronous rotation of the lead screw 409 will cause the slider 410 to move downward. The downward movement of the slider 410 will cause the slide bar 415 to slide downward along the circular groove 404, which will cause the stretching roller 406 to move downward. During the downward movement of the stretching roller 406, the color-changing film will be pulled downward, and the wrinkles will disappear, thus facilitating the processing of the color-changing film.
