Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figures 1-4 As shown: This embodiment provides a tensioning structure for applying protective film in glass production, including an adaptive adjustment mechanism 200 mounted on the frame 101 of an automatic film applicator 100. There are two adaptive adjustment mechanisms 200, one located on the frame 101 between the automatic unwinding roller and the film applicator, and the other located on the frame 101 between the film applicator and the automatic rewinding roller. Each adaptive adjustment mechanism 200 includes vertical plates 201 mounted on the frame 101 on the front and rear sides in the direction of film application. Each vertical plate 201 has a groove 202, and each groove 202 contains... The device includes a sliding slider 203, with a pressure roller 204 rotating between the two sliders 203. Each slider 203 has a spring 205 at its lower part and an adjusting bolt 206 at its upper part. This invention allows for convenient and quick adjustment of the tension of the pressure roller 204 without stopping the machine, thanks to the adaptive adjustment mechanism 200. This solves the problem that traditional film applicators often have cumbersome tensioning structures that cannot adaptively adjust according to the film applicator's progress and require frequent machine stops for adjustment, which greatly reduces the efficiency and effectiveness of the protective film application.

[0023] According to one embodiment of the present invention, such as Figures 1-4As shown, each groove 202 has a limiting cylinder 207 at its lower part, and the lower part of the spring 205 is located inside the limiting cylinder 207 on the same side. Each spring 205 has a support rod 208 at its upper part, and the upper part of each support rod 208 is fixed together with the lower part of the slider 203 on the same side. This utility model can realize the elastic adaptive support operation of the slider 203 by the supporting effect of the spring 205 after compression and recovery of elasticity, which is convenient to adapt to the adaptive adjustment of the pressing degree of the pressing roller 204, and the operation is more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, each slider 203 has a guide cylinder 209 on its upper part, and an adjusting bolt 206 is provided on the axis of each guide cylinder 209. A threaded hole 210 is provided on the upper part of the slide groove 202 and on the axis of the guide cylinder 209. The adjusting bolt 206 passes through and is threaded into the threaded hole 210. This utility model can adjust the distance between the lower part of the adjusting bolt 206 and the upper part of the slider 203 by turning the adjusting bolt 206, thereby limiting the jump range of the elastic support of the spring 205 on the slider 203. This makes it easier to adapt to the pressing and fixing of protective films with different pressing requirements, and the operation is more convenient and efficient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, bearings are provided at both ends of the pressure roller 204. The outer ring of each bearing is fixed on the inner wall of the slider 203 located on the same side. This utility model can realize the rotational connection between the pressure roller 204 and the slider 203 through the bearings. Furthermore, the protective film can be flattened by rotating the pressure roller 204 during the process of conveying and pressing the protective film, making the operation more convenient.

[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the pressure roller 204 is an anti-static roller, which can prevent static electricity generated by friction between the pressure roller 204 and the protective film from entering the air.

[0027] The adsorption of dust in the air affects the protective effect of the protective film.

[0028] The outer thread of the adjusting bolt 206 is connected to a limit nut. This utility model can lock the adjusting bolt 206 after it has been adjusted by the limit nut, which greatly increases the stability of the adaptive adjustment range of the limit roller after adjustment.

[0029] How to use this utility model:

[0030] First, it needs to be clear that the tensioning structure involved in the utility model is mainly used for the compression adjustment operation of the film during the film coating or winding process, and the use method is described in detail taking the adjustment of the compression and fixation during the glass protective film pasting process as an example. When the protective film needs to be compressed and tightened, the corresponding adjusting bolt 206 is rotated clockwise to the same number of turns (of course, it can also be adjusted adaptively according to the placement angle of the protective film peeling), then the operator passes the protective film through the first adaptive adjusting mechanism 200, the film pasting machine, the second adaptive adjusting mechanism 200, and then bypasses the winding roller, and then the automatic film pasting machine 100 can be started to perform the film pasting operation. When the protective film needs to be compressed and loosened, the corresponding adjusting bolt 206 is rotated counterclockwise to the same number of turns, and the utility model can realize the elastic support of the sliding block 203 through the spring 205 and the top rod, and can realize the adaptive adjustment operation of the compression adjustment range of the limiting block under the elastic support assembly and the elastic force of the protective film through the adjustment of the height of the limiting bolt, without frequent shutdown adjustment, and the operation is more efficient and convenient.

[0031] In addition, it should be noted that in the description of the utility model, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0032] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection range of the utility model.
