Description

Technical Field

[0001] This utility model relates to the technical field of coating machines, and in particular to a leveling device for coating machines. Background Technology

[0002] A coating machine is a device used to coat various thin films onto the surface of materials. It uses methods such as physical or chemical vapor deposition to deposit specific materials onto a substrate to change the substrate's properties, such as increasing wear resistance, corrosion resistance, and optical properties.

[0003] When using a coating machine to produce metallized films, before the metallized film enters the traction device, winding device, or rollers, longitudinal wrinkles will appear between the two rollers under tensile stress. The greater the spatial distance, the more severe the wrinkles. If these wrinkles are not eliminated in time, it will lead to inaccurate thickness measurements or gaps when cutting the film, resulting in defects such as film breakage. Therefore, flattening rollers must be installed at the above-mentioned locations for leveling operations.

[0004] The flattening devices used in the existing technology only use flattening rollers to assist in flattening the film roll. However, flattening rollers are thicker in the middle and thinner at both ends. During the film roll process, this makes the middle part of the film relatively tight, while the two ends are relatively loose. In this case, the flattening effect at both ends will be significantly worse, and wrinkles are likely to occur, which brings many inconveniences to the production process and affects the quality and appearance of the product. Utility Model Content

[0005] The purpose of this invention is to provide a leveling device for a coating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leveling device for a coating machine, comprising a base, a mounting frame fixedly connected to the top of the base, a flattening roller rotatably disposed inside the mounting frame, and an adjustment mechanism disposed inside the mounting frame, the adjustment mechanism comprising:

[0007] A sleeve, which is symmetrically and fixedly embedded inside the mounting frame;

[0008] The telescopic frame is slidably inserted into the inner cavity of the sleeve;

[0009] A screw, one end of which is rotatably inserted into the inner wall of the sleeve, and the other end of which is threaded into the inner cavity of the telescopic bracket;

[0010] An auxiliary roller, which is rotatably mounted on a telescopic frame;

[0011] A positioning component is disposed at the top end of the sleeve to limit the rotation of the screw.

[0012] Preferably, the positioning component includes:

[0013] A fixing block, which is fixedly connected to the top end of the sleeve;

[0014] A turntable, which is fixedly connected to one end of a screw;

[0015] An extrusion plate, wherein the inside of the fixing block is provided with an extrusion groove, and the extrusion plate is located inside the extrusion groove;

[0016] A positioning rod, one end of which is fixedly connected to the extrusion plate, and positioning holes are equidistantly opened on the outer wall of the turntable. The other end of the positioning rod is slidably inserted into the inner cavity of the positioning hole.

[0017] A compression spring, which is sleeved on the outside of the positioning rod.

[0018] Preferably, one end of the compression spring is fixedly connected to the extrusion plate, and the other end of the compression spring is fixedly connected to the inner wall of the extrusion groove.

[0019] Preferably, the top and bottom ends of the telescopic frame are fixedly connected to limit blocks, and the top and bottom ends of the inner wall of the sleeve are provided with limit grooves, and the limit blocks and the inner cavities of the limit grooves are slidably interlocked.

[0020] Preferably, the auxiliary roller has a rotating groove inside, and a rotating block is provided inside the rotating groove. One end of the telescopic frame is fixedly connected to the rotating block.

[0021] Preferably, the outer walls of the telescopic frame and the rotating block are both equidistantly fitted with ball bearings, which are used to fit the auxiliary roller.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] This invention utilizes a combination of a sleeve, a telescopic frame, a screw, auxiliary rollers, and a positioning component. Auxiliary rollers are positioned above both sides of the flattening roller, working in conjunction with it. The outer diameter of the auxiliary rollers decreases progressively from one side to the other, with one end having a larger diameter and the other a smaller diameter. These two auxiliary rollers on both sides extend the film's path at both ends, thus tightening the film and preventing slack that could lead to poor flattening and wrinkles, thereby improving the product's appearance. The position of the auxiliary rollers can be adjusted by rotating the screw, adapting to different film specifications. After adjustment, the positioning component limits the position, preventing further changes and enhancing the stability and ease of use of the entire device. Attached Figure Description

[0029] 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.

[0030] This utility model provides, for example Figure 1-4The coating machine leveling device shown includes a base 1, with a mounting frame 2 fixedly connected to the top of the base 1. A leveling roller 3 is rotatably mounted inside the mounting frame 2. An adjusting mechanism 4 is also installed inside the mounting frame 2. The adjusting mechanism 4 includes a sleeve 41, a telescopic frame 42, a screw 43, an auxiliary roller 44, and a positioning component 45. The sleeve 41 is symmetrically fixedly embedded inside the mounting frame 2. The telescopic frame 42 is slidably inserted into the inner cavity of the sleeve 41. One end of the screw 43 is rotatably inserted into the inner wall of the sleeve 41, and the other end of the screw 43 is threaded into the inner cavity of the telescopic frame 42. The auxiliary roller 44 is rotatably mounted on the telescopic frame 42. The positioning component 45 is located at the top of the sleeve 41 and is used to limit... When the screw 43 rotates, auxiliary rollers 44 are set above both sides of the flattening roller 3. The outer diameter of the auxiliary rollers 44 decreases from one side to the other, with one end having a larger diameter and the other end having a smaller diameter. The two auxiliary rollers 44 on both sides can extend the film path at both ends, thereby tightening the two ends of the film and avoiding slack that would lead to poor flattening effect and wrinkles in the film, which is beneficial to improving the product appearance. At the same time, the position of the auxiliary rollers 44 can be adjusted by rotating the screw 43, so as to be suitable for use with films of different specifications. After adjustment, the position is limited by the positioning component 45 to prevent the position from changing again, further improving the stability of the entire device and making it easy to use.

[0031] The positioning assembly 45 includes a fixing block 451, a turntable 452, an extrusion plate 453, a positioning rod 454, and a compression spring 455. The fixing block 451 is fixedly connected to the top of the sleeve 41, and the turntable 452 is fixedly connected to one end of the screw 43. The turntable 452 can drive the screw 43 to rotate, thereby adjusting the telescopic length of the telescopic frame 42. This allows the auxiliary roller 44 to move along the inclined surface of the flattening roller 3, thus adapting to different film specifications. The fixing block 451 has an extrusion groove inside, and the extrusion plate 453 is located inside the extrusion groove. One end of the positioning rod 454 is fixedly connected to the extrusion plate 453. The outer wall of the turntable 452, etc. A positioning hole is provided at the distance, and the other end of the positioning rod 454 is slidably inserted into the inner cavity of the positioning hole. A compression spring 455 is sleeved on the outside of the positioning rod 454. One end of the compression spring 455 is fixedly connected to the extrusion plate 453, and the other end of the compression spring 455 is fixedly connected to the inner wall of the extrusion groove. The compression spring 455 is always in a compressed state, so that the extrusion plate 453 can provide a stable elastic force to the positioning rod 454, thereby making the positioning rod 454 and the positioning hole of the turntable 452 lock stably. The locking of the positioning rod 454 and the positioning hole can prevent the turntable 452 from being accidentally touched, which may lead to the possibility of misalignment of the adjustment.

[0032] Limiting blocks 5 are fixedly connected to the top and bottom of the telescopic frame 42. Limiting grooves are opened at the top and bottom of the inner wall of the sleeve 41. The limiting blocks 5 are slidably inserted into the inner cavity of the limiting grooves. The setting of the limiting blocks 5 plays a limiting role in the telescopic frame 42, so that when the screw 43 rotates, the telescopic frame 42 can only move along the limiting grooves.

[0033] The auxiliary roller 44 has a rotating groove inside, and a rotating block 6 is set inside the rotating groove. One end of the telescopic frame 42 is fixedly connected to the rotating block 6. Ball bearings 7 are embedded at equal intervals on the outer walls of both the telescopic frame 42 and the rotating block 6. The ball bearings 7 are used to fit the auxiliary roller 44. The setting of the ball bearings 7 reduces the friction between the telescopic frame 42 and the auxiliary roller 44, making the rotation of the auxiliary roller 44 more convenient.

[0034] 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.
