[0002] Coating machines, as key equipment widely used in printing, packaging, electronics, textiles, and other industries, primarily function to evenly coat the substrate surface with coatings to achieve the required coating thickness and uniformity. The quality of the coating directly affects the quality of the final product and production efficiency. In the production of automotive window safety film, a composite adhesive is applied to a PET base layer before being overlapped and bonded to a metal heat insulation layer, a UV absorption layer, and an anti-wear layer.
[0003] During coating, both the PET polyester film and the coating roller are prone to misalignment, affecting coating quality. Existing correction devices include at least two spindles mounted on a frame and correction guide rollers corresponding to and fitted onto the spindles. The correction guide rollers can rotate around the spindles, are located on both sides of the PET polyester film, and their outer circumference abuts against the PET polyester film. The central axis of the correction guide rollers is set at an angle to the transport direction of the PET polyester film.
[0004] However, the existing coating roller correction devices of coating machines mostly have a fixed height, which is not convenient to adjust the correction height according to the usage requirements and has low flexibility. At the same time, the width of some correction devices is fixed, which is not convenient to adjust according to the width of PET polyester film, affecting the correction effect. Therefore, it needs to be improved. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0033] This application discloses a coating roller correction device for a coating machine. (Refer to...) Figure 1A coating roller correction device for a coating machine includes a fixed base 1, with a fixed frame 3 mounted above the fixed base 1. The fixed frame 3 is suspended above the fixed base 1 via support legs. A rotating roller 2 is rotatably inserted into the inner side of the fixed frame 3 via a rotating shaft. The position of the rotating roller 2 is relatively fixed and will not move. Two sets of rotating rollers 2 are arranged side-by-side within the fixed frame 3, along the direction of fabric movement. An L-shaped plate 10 is positioned above the two sets of rotating rollers 2, mounted on the fixed frame 3, with its vertical projection located between the two sets of rotating rollers 2. The combined action of the rotating rollers 2 and the L-shaped plate 10 restricts the fabric conveying.
[0034] Reference Figure 1 and Figure 2 A round rod 4 is movably mounted on the top of the fixed base 1 via a limiting block, and gears 5 are fixedly sleeved on both sides of the round rod 4. A motor 11 is installed on one side of the round rod 4.
[0035] Reference Figure 2 and Figure 3 The fixed base 1 has two fixed posts 6 on its top ends, and a sliding post 8 is movably inserted into the fixed post 6. A rack post 7 is embedded in the sliding post 8. Two sets of fixed posts 6 are symmetrically arranged, and a square groove 13 is opened on the front of each set of fixed posts 6. The gear 5 is movably inserted into the square groove 13. This allows the gear 5 to contact the rack post 7, so that the gear 5 and the rack post 7 can mesh and move, thereby driving the sliding post 8 to move up and down.
[0036] Reference Figure 1 and Figure 2 A movable plate 9 is fixed to the top of the sliding column 8. The movable plate 9 is connected to the L-shaped plate 10 to drive the L-shaped plate 10 to move up and down. There are two L-shaped plates 10, one on the left and one on the right, with each movable plate 9 connected to one L-shaped plate 10. Grooves 12 are formed vertically on both sides of the fixed frame 3, and the movable plates 9 are movably inserted into the grooves 12. This allows the movable plates 9 to move up and down more stably, improving stability during use.
[0037] When the operating height needs to be increased, start motor 11. The output end of motor 11 drives the round rod 4 and gear 5 to rotate clockwise. After the gear 5 rotates clockwise and passes through the square groove 13, it drives the meshing rack column 7 to move upward. The movement of rack column 7 causes the sliding column 8 to move upward in the fixed column 6. Thus, the sliding column 8 pushes the moving plate 9 upward in the groove 12, increasing the operating height of the moving plate 9 and L-shaped plate 10. When the operating height needs to be lowered, the same principle applies: the output end of motor 11 drives the round rod 4 to rotate counterclockwise.
[0038] Reference Figure 4 and Figure 5The top of the movable plate 9 is provided with a sliding groove 16, and the bottom of the L-shaped plate 10 is fixed with a sliding plate 15, which is slidably inserted into the sliding groove 16. One side of one L-shaped plate 10 is fixed with an insert block 14, and the side wall of the other L-shaped plate 10 is provided with a groove that matches the insert block 14. The insert block 14 is slidably inserted into the other L-shaped plate 10, and the two L-shaped plates 10 are slidably engaged by the insert block 14.
[0039] In order to adjust and fix the position of the L-shaped plate 10 and the movable plate 9 to meet different width requirements, multiple sets of reserved holes are opened on the surface of the movable plate 9. A screw 17 is slidably inserted into the top of the sliding plate 15. One end of the screw 17 moves through the sliding plate 15 and extends into the reserved hole of the movable plate 9. The screw 17 and the movable plate 9 are inserted and set by screw rotation.
[0040] When it is necessary to increase the usable width, hold both sets of L-shaped plates 10 and move them to both sides at the same time, so that the insert 14 slides in the L-shaped plates 10, thereby increasing the usable length of the L-shaped plates 10. Then, as the two sets of L-shaped plates 10 move, the sliding plate 15 moves and slides inward in the slide groove 16. After moving to the appropriate position, the sliding plate 15 and the moving plate 9 are fixed by the screw 17. When it is necessary to reduce the usable width, the operation is reversed in the same way.
[0041] The implementation principle of the coating roller correction device of the coating machine in this application embodiment is as follows: the whole is placed in a suitable position, and the height is adjusted according to the needs of use. When it is necessary to raise the height, the motor 11 is started. The output end of the motor 11 drives the round rod 4 and the gear 5 to rotate clockwise. After the gear 5 rotates clockwise and passes through the square groove 13, it drives the meshing rack column 7 to move upward. The movement of the rack column 7 causes the sliding column 8 to move upward in the fixed column 6. Thus, the sliding column 8 pushes the moving plate 9 to move upward in the groove 12, and the height of the moving plate 9 and the L-shaped plate 10 increases. When it is necessary to lower the height, the output end of the motor 11 drives the round rod 4 to rotate counterclockwise in the opposite direction.
[0042] Next, when it is necessary to increase the usable width, hold both sets of L-shaped plates 10 and move them to both sides at the same time, so that the insert block 14 slides in the L-shaped plate 10, thereby increasing the usable length of the L-shaped plate 10. Then, as the two sets of L-shaped plates 10 move, the sliding plate 15 moves and slides inward in the slide groove 16. After moving to the appropriate position, the sliding plate 15 and the moving plate 9 are fixed by the screw 17. When it is necessary to reduce the usable position, the same reverse operation can be performed. Finally, after adjusting to the appropriate usable position, place the PET polyester film under the L-shaped plate 10.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
