A high-precision protective film coating guide device

Abstract

This utility model discloses a high-precision protective film coating guiding device, comprising: a guide roller, a first mounting frame, and a second mounting frame. The first mounting frame is disposed on one side of the guide roller, and a first limiting component for rotating the guide roller is disposed at the connection between the guide roller and the first mounting frame. The second mounting frame is disposed on the other side of the first mounting frame. Through the design of the first limiting component, the second limiting component, the connecting component, and the pushing component, this utility model allows the protective film to move at one end of the guide roller when it deviates during use. This tilts the guide roller, causing the protective film to have different contact lengths on both sides of the roller surface. The side with longer contact has a faster linear velocity, pushing the protective film to the other side. The deviated protective film gradually returns to the center position due to the thrust of the tilted guide roller, thus achieving calibration and preventing the film from rolling up due to obstructions during use.

Description

Technical Field

[0001] This utility model relates to the field of guiding device technology, and in particular to a high-precision protective film coating guiding device. Background Technology

[0002] In the protective film coating process, the guiding device is a key component to ensure coating uniformity and avoid edge overflow or missed coating.

[0003] Traditional guiding devices typically consist of a pair of alignment blocks positioned on either side of the protective film. Their working principle involves two fixed, rigid blocks physically limiting the edges of the protective film, thus preventing lateral deviation and ensuring smooth transport along a predetermined path. However, when the protective film continuously shifts to one side, the alignment blocks come into direct frictional contact with the film's edge. Since these blocks are usually made of hard materials and have sharp edges, under continuous lateral pressure, the protective film not only fails to return to its correct position but also warps, folds, or even rolls up entirely due to friction, affecting subsequent coating processes. Therefore, this solution proposes a high-precision protective film coating guiding device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision protective film coating guide device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision protective film coating guide device, comprising:

[0006] Guide rollers;

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The high-precision protective film coating guide device shown includes:

[0024] Guide roller 1;

[0025] The first mounting frame 2 is disposed on one side of the guide roller 1, and a first limiting component 3 for rotating the guide roller 1 is provided at the connection between the guide roller 1 and the first mounting frame 2.

[0026] The second mounting bracket 7 is located on the other side of the first mounting bracket 2. The other side of the guide roller 1 is provided with a second limiting component 4. The connection between the guide roller 1 and the second mounting bracket 7 is provided with a connecting component 6 for adjusting the distance between them. One side of the second mounting bracket 7 is provided with a pushing component 5 for adjusting the height of the other side of the guide roller 1.

[0027] It should be noted that when the protective film deviates, the push component 5 drives one end of the guide roller 1 to move, thereby tilting the guide roller 1. The contact length of the protective film on both sides of the roller surface is different. The side with longer contact has a faster linear speed, pushing the protective film to the other side. The deviated protective film will gradually return to the center position due to the thrust of the tilted guide roller 1, thereby calibrating it and preventing it from rolling up due to obstructions during use.

[0028] Specifically, the first limiting component 3 includes a first connecting shaft 301 fixedly connected to one side of the guide roller 1, a fixed bearing 302 sleeved on one side of the first connecting shaft 301, a first mounting groove 201 opened on the top of the first mounting bracket 2, the fixed bearing 302 inserted into the interior of the first connecting shaft 301, and rotating grooves 304 symmetrically opened on the inner walls of the front and back sides of the first mounting groove 201. Rotating columns 303 are symmetrically fixedly connected to the front and back sides of the fixed bearing 302, and the rotating columns 303 are inserted into the interior of the rotating grooves 304.

[0029] It should be noted that the fixed bearing 302 is an existing ball bearing, which is sleeved on one end of the first connecting shaft 301, allowing the first connecting shaft 301 to rotate in the middle of the fixed bearing 302. The rotating groove 304 on the first mounting groove 201 and the rotating column 303 on the fixed bearing 302 are both cylindrical, allowing the rotating column 303 inserted into the rotating groove 304 to rotate. In this way, the fixed bearing 302 is connected to the first mounting frame 2, so that while the fixed bearing 302 is restricted to the top of the first mounting frame 2, the fixed bearing 302 can rotate on the top of the first mounting frame 2, thereby allowing one end of the guide roller 1 to rotate with the connection between the fixed bearing 302 and the first mounting frame 2 as the center.

[0030] Specifically, the second limiting component 4 includes a second connecting shaft 402 disposed on the other side of the guide roller 1. A movable plate 401 is sleeved on one end of the second connecting shaft 402. Slider 403 is symmetrically fixedly connected to the front and back of the movable plate 401. A second mounting groove 701 is provided in the middle of the second mounting bracket 7. Slide grooves 404 are symmetrically provided on the inner walls of the front and back of the second mounting groove 701. The slider 403 is inserted and connected inside the slide groove 404.

[0031] It should be noted that the second mounting slot 701 is adapted to the movable plate 401, so that the movable plate 401 can be inserted into the interior of the second mounting slot 701. The slider 403 is adapted to the sliding groove 404, and the slider 403 is a cube, so that the slider 403 can move inside the sliding groove 404, but the slider 403 cannot rotate inside the sliding groove 404.

[0032] Specifically, one end of the second connecting shaft 402 is hinged to the connecting rod 8, and the connecting assembly 6 includes a connecting groove 601 opened on the other side of the guide roller 1. The connecting rod 8 is inserted into the interior of the connecting groove 601. A limiting groove 603 is opened on the inner wall of one side of the connecting groove 601. A limiting block 602 is fixedly connected to the other end of the connecting rod 8. The limiting block 602 is inserted into the interior of the limiting groove 603.

[0033] It should be noted that the connecting rod 8 is connected to the second connecting shaft 402 by a hinge, allowing the connecting rod 8 to rotate at one end of the second connecting shaft 402. The limiting groove 603 is adapted to the limiting block 602, allowing the limiting block 602 to slide inside the limiting groove 603. The horizontal longitudinal cross-sectional area of ​​the limiting block 602 is larger than the horizontal longitudinal cross-sectional area of ​​the connecting groove 601, preventing the limiting block 602 from moving out of the limiting groove 603 through the connecting groove 601. When the other side of the guide roller 1 is driven to move by the pushing component 5, one end of the guide roller 1 rotates on the first mounting bracket 2. At this time, driven by the pushing component 5, the second connecting shaft 402 moves away from the guide roller 1 and is connected to the guide roller 1 through the limiting block 602 at one end of the second connecting shaft 402, thus preventing the other end of the guide roller 1 from being unable to move.

[0034] Specifically, the pushing component 5 includes a pushing plate 501 fixedly connected to the bottom end of the moving plate 401, and a cylinder 502 fixedly connected to the bottom end of the second mounting bracket 7. The pushing plate 501 is fixedly connected to the output end of the cylinder 502.

[0035] It should be noted that the cylinder 502 is an existing pneumatic actuator that converts the energy of compressed air into linear reciprocating motion. It mainly consists of a cylinder barrel, piston, piston rod, seals, and end caps. Its working principle is as follows: compressed air enters the cylinder 502 chamber through a solenoid valve, pushing the piston to produce mechanical displacement, which in turn drives the external mechanism to complete the push and pull functions. In use, the cylinder 502 drives the push plate 501 at its output end to move, and the moving push plate 501 drives the other end of the guide roller 1 to move up and down.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
