Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating film technology, specifically a coating roller structure for coating film production. Background Technology
[0002] Coated films are composite materials formed by coating one or more layers of a specific functional coating onto the surface of a substrate film. Coating rollers typically apply the coating evenly to the film substrate through rotational motion. When the coating roller comes into contact with the coating, a certain amount of coating is adsorbed onto its surface; as the roller rotates, the coating is transferred to the film surface.
[0003] However, the film may shift or deviate on other guide and auxiliary rollers during the dragging process, which will affect the coating effect of the coating roller. Therefore, it is necessary to correct or limit its deviation.
[0004] Therefore, this utility model provides a coating roller structure for coating film production to solve the above problems. Utility Model Content

[0011] Furthermore, the auxiliary component includes a docking block, and rollers are rotatably connected between the inner walls of the docking block.
[0012] By adopting the above technical solution, the concave plate can be supported and moved at the same time.

[0017] Beneficial effects
[0018] This invention provides a coating roller structure for producing coated films. Compared with the prior art, it has the following advantages:
[0019] 1. The coating roller structure used in the production of coated films is set before the coating spraying mechanism. When the film is dragged and moved, it will pass over the surface of the roller. Two correction rods inside the roller are used to restrict the moving film to prevent it from deviating and ensure that the coating mechanism can fully coat it. By starting the first servo motor, the bidirectional lead screw is driven to rotate. The bidirectional lead screw then drives the two nut blocks to move closer or further apart. The correction rods, in conjunction with the through groove, can restrict the rotation of the nut blocks and make them move in a straight line. The correction rods will also move closer or further apart with the nut blocks. In this way, it can be adjusted according to the width of the film. The slide bar can make the concave plate more stable when the whole is moving.
[0020] 2. The coating roller structure used in the production of coated films, by starting the second servo motor, drives the horizontal lead screw to rotate. The horizontal lead screw, under the restriction of the limit rod, causes the docking block to move. The docking block can then drive the concave plate to move, thereby adjusting the position of the roller as a whole and smoothing out the wrinkled film again through friction with the roller.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] Reference Figures 1 to 4This application provides a coating roller structure for film coating production, including an assembly plate 1. A limiting component 2 is provided on one side of the assembly plate 1, and an auxiliary component 3 is also provided on one side of the assembly plate 1. The limiting component 2 includes a concave plate 21, with a rotating roller 22 rotatably connected to the inner sidewalls of both ends of the concave plate 21. A first bracket 25 is fixedly connected inside the rotating roller 22, and a bidirectional lead screw 26 is rotatably connected between the two first brackets 25. A nut block 27 is threadedly connected to the outer wall of the bidirectional lead screw 26, and a correction rod 28 is fixedly connected to the outer wall of the nut block 27. A through groove 23 is opened inside the sidewall of the rotating roller 22, and the correction rod 28 is slidably connected to the inner wall of the through groove 23. A second bracket 29 is fixedly connected to the inner wall of the rotating roller 22, and a first servo motor 210 is fixedly installed on the inner wall of the second bracket 29. The output shaft of the first servo motor 210 is fixedly connected to one end of the bidirectional lead screw 26. Sliding rods 24 are fixedly connected to both sides of the rotating roller 22, and the sliding rods 24 are slidably connected to the interior of the assembly plate 1.
[0030] In specific implementation: the device is set before the coating spraying mechanism. When the film is dragged and moved, it will pass over the surface of the rotating roller 22. The two correction rods 28 inside the rotating roller 22 are used to restrict the moving film to prevent it from deviating and ensure that the coating mechanism can fully coat it. By starting the first servo motor 210, the bidirectional lead screw 26 is driven to rotate. The bidirectional lead screw 26 then drives the two nut blocks 27 to move closer or further away from each other. The correction rods 28, together with the through groove 23, can restrict the nut blocks 27 to prevent them from rotating and make them move in a straight line. The correction rods 28 will also move closer or further away from each other with the nut blocks 27. In this way, it can be adjusted according to the width of the film. The slide bar 24 can make the concave plate 21 more stable when it moves as a whole.
[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the auxiliary component 3 includes a docking block 31, with rollers 32 rotatably connected between the inner walls of the docking block 31. A horizontal lead screw 33 is rotatably connected between two assembly plates 1, and the horizontal lead screw 33 is threadedly connected to the inside of the docking block 31. A limit rod 34 is also fixedly connected between the two assembly plates 1, passing through the docking block 31 and movably connected thereto. The auxiliary component 3 also includes a second servo motor 35, the output shaft of which is fixedly connected to one end of the horizontal lead screw 33.
[0032] In practice: by starting the second servo motor 35, the horizontal lead screw 33 is driven to rotate. The horizontal lead screw 33 is then restricted by the limit rod 34, causing the docking block 31 to move. The docking block 31 can then drive the concave plate 21 to move, thereby adjusting the position of the rotating roller 22 as a whole. The wrinkled film is then smoothed out again by friction with the rotating roller 22.
[0033] All electrical devices in this plan are powered by an external power source.
[0034] Working principle: This device is placed before the coating spraying mechanism. When the film is dragged and moved, it passes over the surface of the rotating roller 22. The two correction rods 28 inside the rotating roller 22 are used to restrict the moving film to prevent it from deviating and ensure that the coating mechanism can fully coat it. By starting the first servo motor 210, the bidirectional lead screw 26 is driven to rotate. The bidirectional lead screw 26 then drives the two nut blocks 27 to move closer or further apart. The correction rods 28, in conjunction with the through groove 23, can restrict the rotation of the nut blocks 27 and make them move in a straight line. The correction rods 28 will also move closer or further apart with the nut blocks 27. In this way, it can be adjusted according to the width of the film. The slide bar 24 can make the concave plate 21 move more smoothly when the whole movement is made. By starting the second servo motor 35, the horizontal lead screw 33 is driven to rotate. The horizontal lead screw 33 then causes the docking block 31 to move under the restriction of the limit rod 34. The docking block 31 then drives the concave plate 21 to move, thereby adjusting the position of the rotating roller 22 as a whole. The wrinkled film is straightened again by friction with the rotating roller 22.
