Abstract
Description
Technical Field
[0001] This utility model belongs to the field of antistatic film technology, specifically relating to a high-temperature resistant, wear-resistant, durable antistatic film. Background Technology
[0002] As a type of functional film, antistatic film has a surface resistance within a certain range, which can effectively prevent the accumulation and discharge of static electricity, thereby protecting the wrapped items from static damage.
[0003] When processing antistatic films, operators often choose to use polyimide materials because polyimide has extremely high temperature resistance and wear resistance, as well as good chemical stability and electrical properties. Therefore, antistatic films made from polyimide possess high temperature resistance, wear resistance, and durability. However, when the antistatic film is wound onto a winding drum after processing, if the film is not completely used, the head of the film will be spread out on the drum. If the antistatic film is simply left lying around, the head of the film may become scattered on the winding drum, affecting its future use.
[0004] Therefore, this utility model provides a high-temperature resistant, wear-resistant, durable, and antistatic film to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a high-temperature resistant, wear-resistant, durable antistatic film, which aims to solve the problem in the prior art that when the antistatic film on the winding drum is not used up, the head of the antistatic film will be spread out on the winding drum. If the antistatic film is placed directly, the head of the antistatic film will easily become scattered on the winding drum.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant, wear-resistant, durable, and antistatic film, comprising an antistatic film body and a winding cylinder. The antistatic film body is wound around the outer surface of the winding cylinder, and an installation block is connected to the inner surface of the top end of the winding cylinder. An installation frame is connected to the top surface of the installation block. A through-hole movable groove is opened on the top surface of one end of the installation frame. A bearing is connected to the left side surface inside the movable groove. A screw is connected to the inner surface of the bearing. A movable block is through-hole connected to one end of the screw. A clamping plate is connected to the bottom surface of the movable block. A rubber block is connected to the left side surface of the clamping plate facing the antistatic film body.
[0007] In order to enable the clamping plate to move, as a preferred embodiment of the high temperature resistant, wear resistant, durable and antistatic film of this utility model, the moving block and the screw are connected by a thread, and the moving block is connected to the mounting frame by a moving groove.
[0008] To facilitate the rotation of the screw, in a preferred embodiment of the high-temperature resistant, wear-resistant, durable, and antistatic film of this invention, one end of the screw passes through the right side surface of the mounting block, and the end of the screw passing through the right side surface of the mounting block is connected to a rotating block.
[0009] In order to better compress and fix the head position of the antistatic film body, as a preferred embodiment of the high temperature resistant, wear resistant and durable antistatic film of this utility model, the rubber block has an arc-shaped groove on the left side surface facing the antistatic film body.
[0010] To enable bolt installation, as a preferred embodiment of the high-temperature resistant, wear-resistant, durable, and antistatic film of this utility model, a bolt is connected through the top of the mounting bracket, and a threaded hole for threaded connection with the bolt is provided on the top surface of the mounting block.
[0011] In order to enable the mounting bracket to rotate, the mounting bracket and the bolt are fixedly connected, which is a preferred embodiment of the high temperature resistant, wear resistant, durable and antistatic film of this utility model.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes the interplay of a clamping plate and a rubber block. Rotating the screw within the bearing causes a moving block on the screw to move along a groove, bringing the clamping plate closer to the antistatic film body. This allows the rubber block on one side of the clamping plate to contact the antistatic film body, compressing and securing the antistatic film body to prevent it from becoming scattered on the winding cylinder. Furthermore, rotating the bolt within the threaded hole allows the mounting block to rotate, enabling the clamping plate on the mounting block to clamp and secure the head of the antistatic film body at any position on the winding cylinder.

[0020] 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.
[0021] Please see Figures 1-4 The present invention provides the following technical solution: a high-temperature resistant, wear-resistant, durable, and antistatic film, comprising an antistatic film body 1 and a winding cylinder 2. The antistatic film body 1 is wound on the outer surface of the winding cylinder 2, and an installation block 3 is connected to the inner surface of the top end of the winding cylinder 2. An installation frame 4 is connected to the top surface of the installation block 3. A through moving groove 5 is opened on the top surface of one end of the installation frame 4. A bearing 6 is connected to the left side surface inside the moving groove 5. A screw 7 is connected to the inner surface of the bearing 6. A moving block 8 is connected through one end of the screw 7. A clamping plate 9 is connected to the bottom surface of the moving block 8. A rubber block 10 is connected to the left side surface of the clamping plate 9 facing the antistatic film body 1.
[0022] The antistatic film body 1 is made of polyimide material, which can be used for a long time in a temperature range of -269°C to 260°C, thus having extremely high temperature resistance. At the same time, the tensile strength of polyimide material is above 100 MPa, so it has excellent wear resistance. In addition, polyimide material also has good chemical stability and electrical properties, and can maintain stable performance in various environments. It is not easily corroded by chemical substances, so it has excellent durability. Therefore, the antistatic film body 1 made of polyimide material has good high temperature resistance, wear resistance and durability.
[0023] Preferably, the movable block 8 and the screw 7 are connected by a thread, and the movable block 8 is connected to the mounting bracket 4 by a sliding connection through the movable groove 5.
[0024] In practical use, when the screw 7 rotates, the moving block 8 on the screw 7 will move along the moving groove 5 on the mounting bracket 4, thereby driving the clamping plate 9 to move.
[0025] Preferably, one end of the screw 7 passes through the right side surface of the mounting block 3, and a rotating block is connected to the end of the screw 7 that passes through the right side surface of the mounting block 3.
[0026] In practical use, by turning the rotating block, the rotating block can drive the screw 7 to rotate in the bearing 6.
[0027] Preferably, the rubber block 10 has an arc-shaped groove on the left side surface facing the antistatic film body 1.
[0028] In practical use, the arc-shaped groove on the inner side of the rubber block 10 can increase the contact surface between the rubber block 10 and the antistatic film body 1, so that the rubber block 10 can more firmly squeeze and fix the antistatic film body 1.
[0029] Preferably, a bolt 11 is connected through the top of the mounting bracket 4, and a threaded hole 12 is provided on the top surface of the mounting block 3 for threaded connection with the bolt 11.
[0030] In practical use, one end of the bolt 11 that passes through the mounting bracket 4 is screwed into the threaded hole 12 at the top of the mounting block 3, so that the mounting bracket 4 can be fixed on the mounting block 3 by the bolt 11. Then, rotating the bolt 11 can move the mounting bracket 4. At the same time, turning the bolt 11 can also remove the mounting bracket 4 from the mounting block 3, so that the mounting bracket 4 can be repeatedly installed on the mounting blocks 3 in other winding cylinders 2 for use.
[0031] Preferably, the mounting bracket 4 and the bolt 11 form a fixed connection.
[0032] In actual use, by rotating bolt 11, the mounting bracket 4 can be rotated together with bolt 11.
[0033] Working principle: When using this high-temperature resistant, wear-resistant, and durable antistatic film, after the antistatic film body 1 is wound around the outer surface of the winding cylinder 2, the mounting block 3 is fixed to the inner side of the top of the winding cylinder 2 with adhesive. Then, one end of the bolt 11 passing through the mounting block 3 is screwed into the threaded hole 12 on the mounting block 3, so that the mounting block 3 is installed at the top of the winding cylinder 2. At this time, the clamping plate 9 set at one end of the mounting block 3 will be on the outside of the antistatic film body 1. At this time, the rubber block 10 on the inner side of the clamping plate 9 will not be in contact with the antistatic film body 1, allowing the operator to use the antistatic film body 1 on the winding cylinder 2 normally. When the antistatic film body 1 is used up, the head of the antistatic film body 1 is in the unfolded state on the winding cylinder 2. At this time, by rotating the bolt 11 in the threaded hole 12, the bolt 11 can drive the mounting block 3 to rotate, so that the clamping plate 9 on the outside of the antistatic film body 1 will move to the outside of the winding cylinder 2. At the head position of the antistatic film body 1, the screw 7 is rotated in the bearing 6 by the rotating block, which allows the moving block 8 on the screw 7 to move along the moving groove 5 on the mounting block 3. In this way, the moving block 8 can bring the clamping plate 9 closer to the antistatic film body 1. After adjustment, the rubber block 10 on the inner side of the clamping plate 9 can contact the antistatic film body 1. By slightly squeezing the rubber block 10, the head position of the antistatic film body 1 can be squeezed and fixed on the winding cylinder 2. In this way, when the antistatic film body 1 is placed, it can prevent the head of the antistatic film body 1 from being scattered on the winding cylinder 2. Secondly, when the antistatic film body 1 on the winding cylinder 2 needs to be used again, the screw 7 can be rotated again to move the moving block 8 to move the clamping plate 9 outward, so that the rubber block 10 can be separated from the antistatic film body 1, and the antistatic film body 1 on the winding cylinder 2 can be used normally.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
