Description

Technical Field

[0001] This utility model relates to a separation device, specifically, a device for separating reflective film and release paper. Background Technology

[0002] Reflective film is a pre-made thin film that can be applied directly. During license plate manufacturing, reflective film is applied to an aluminum plate before the plate is die-cut to its desired shape. The purpose of applying reflective film is to ensure that the license plate reflects a certain amount of light when illuminated by headlights, thus serving as a warning to vehicles behind.

[0003] In existing technologies, reflective film is laminated onto release paper. When applying reflective film to an aluminum plate, the reflective film needs to be separated from the release paper, then the roll of reflective film is loaded, and finally laminated onto the aluminum plate. Current technologies typically involve manual separation of the reflective film and release paper, which is difficult to perform and the separated reflective film is prone to attracting impurities. These are the shortcomings of existing technologies. Utility Model Content

[0008] A further improvement of this utility model is that a limit plate is provided at the lower end of the lifting rod, and the spring is fixedly connected to the limit plate.

[0009] A further improvement of this invention is that the damping plate is arc-shaped and can wrap around the upper end of the first rotating roller.

[0010] A further improvement of this utility model is that the sleeve is fixed to the support plate via a connecting plate.

[0011] The beneficial effects of this utility model are as follows: In this application, the first rotating roller is used to wind the composite layer of reflective film and release paper, the second rotating roller is used to wind the reflective film, and the third rotating roller is used to wind the release paper.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0017] like Figure 1-3 As shown, a reflective film and release paper separation device includes a base plate 1, on which two support plates 2 are fixed. A first rotating roller 3 for supporting the composite layer is arranged between the two support plates 2. A second rotating roller 4 for supporting the reflective film and a third rotating roller for supporting the release paper are symmetrically arranged on both sides below the first rotating roller 3. The axes of the second rotating roller 4 and the third rotating roller are on the same horizontal plane. The second rotating roller 4 and the third rotating roller are driven to rotate by a rotation drive mechanism 5.

[0018] In this application, the first rotating roller 3 is used to wind the composite layer of reflective film and release paper, the second rotating roller 4 is used to wind the reflective film, and the third rotating roller is used to wind the release paper. The first rotating roller 3, the second rotating roller 4, and the third rotating roller can all rotate between the two support plates 2. The second rotating roller 4 and the third rotating roller are driven by the rotation drive mechanism 5 to move synchronously, ensuring that the reflective film and release paper maintain stable and synchronous movement during the separation process. As the reflective film gradually winds onto the second rotating roller 4 and the release paper gradually winds onto the third rotating roller, the composite layer on the first rotating roller 3 is gradually released outwards, significantly improving the separation efficiency of the reflective film and the release paper.

[0019] Specifically, the rotation drive mechanism 5 includes a motor 51, which is connected to a first gear 52 via a belt drive. The first gear 52 meshes with a second gear 53 and a third gear 54. The second gear 53 is fixed to a second rotating shaft 55, and both ends of the second rotating shaft 55 are rotatably connected to two support plates 2. A second rotating roller 4 is fixed on the second rotating shaft 55. The third gear 54 is fixed to a third rotating shaft 56, and both ends of the third rotating shaft 56 are rotatably connected to two support plates 2. The third rotating roller is fixed on the third rotating shaft 56. The motor drives the first gear 52 to rotate via the belt drive, which in turn drives the second gear 53 and the third gear 54 to rotate. The second gear 53 drives the second rotating shaft 55 to rotate, and the second rotating shaft 55 drives the second rotating roller 4 to rotate. The third gear 54 drives the third rotating shaft 56 to rotate, and the third rotating shaft 56 drives the third rotating roller to rotate.

[0020] In this application, the second rotating roller 4 is fixed on the second rotating shaft 55, and the third rotating roller is fixed on the third rotating shaft 56, thereby realizing independent and synchronous driving of the reflective film and the release paper.

[0021] Furthermore, the first rotating roller 3 is fixed on the first rotating shaft 6, and both ends of the first rotating shaft 6 are rotatably connected to two support plates 2; a damping structure 7 is provided on the outer side of the first rotating shaft 6. The function of the damping structure 7 is to ensure that the first rotating roller receives appropriate resistance during rotation, which not only ensures the smooth passage of the composite layer, but also avoids the phenomenon of pulling, wrinkling or damage caused by excessive rotation speed.

[0022] Specifically, the damping structure 7 includes a sleeve 72, a spring 73, a lifting rod 74, and a damping plate 75. The sleeve 72 is fixed to the support plate 2 and is sleeved over the outside of the lifting rod 74, allowing the lifting rod to slide and rise within the sleeve. A spring 73 is provided between the lower end of the lifting rod 74 and the upper end of the sleeve 72. The bottom end of the lifting rod 74 is fixedly connected to the damping plate 75. In its natural state, the spring 73 drives the damping plate 75 to make close contact with the first transmission roller, thereby generating resistance to the rotation of the first rotating roller 3 and having a certain damping effect.

[0023] To further optimize the damping structure 7, a limiting plate 71 is provided at the lower end of the lifting rod 74, and the spring 73 is fixedly connected to the limiting plate 71. Specifically, the spring 73 is fixed to the limiting plate 71 by welding, and the spring 73 is fixed to the top end of the sleeve 72 by welding.

[0024] Furthermore, the damping plate 75 is arc-shaped and can wrap around the upper end of the first rotating roller 3. This shape can wrap around the upper end of the first rotating roller 3, thereby providing a more uniform and effective damping effect.

[0025] Furthermore, the sleeve 72 is fixed to the support plate 2 by the connecting plate 8, which ensures the stability of the sleeve 72.

[0026] In use, the entire roll of reflective film and release paper composite layer is first fixed onto the first rotating roller, and the ends of the composite layer are separated, so that the end of the reflective film is fixed onto the second rotating roller, and the end of the release paper is fixed onto the first rotating roller. The motor is turned on, and the motor drives the first and second rotating rollers to rotate, which simultaneously releases the composite layer outward, completing the separation process of the reflective film and the release paper.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
