Description

Technical Field

[0001] This utility model relates to the field of antistatic film technology, specifically to an assembled PVC antistatic film. Background Technology

[0002] PVC antistatic film is an antistatic film made of polyvinyl chloride (PVC) with a modular assembly structure. It is especially suitable for places that require convenient installation, replacement and maintenance of antistatic surfaces, such as electronic workshops, clean rooms, laboratory workbenches, equipment protective covers, antistatic floor coverings, etc. Prefabricated PVC antistatic film refers to PVC antistatic film components that are prefabricated in the factory and then assembled on the construction site.

[0003] For example, an antistatic PVC film according to Chinese patent application number CN202122578853.1 can be used for assembly. This film includes a base film, with antistatic films on both sides of the base film surface. An adhesive layer is provided on one side of the antistatic film, and a release film is provided on the surface of the adhesive layer. An installation mechanism is provided on the outside of the release film. This antistatic PVC film, through the antistatic film, provides antistatic protection to both sides of the base film. When laminating the PVC film, it effectively prevents dust from adhering to the surface, keeping the PVC film surface clean. Simultaneously, through the adhesive layer and release film, when bonding the PVC film is required, the release film can be directly peeled off, and then the adhesive layer can be used for bonding.

[0004] However, in actual use, when assembling the above-mentioned device, due to the different sizes and thicknesses of the PVC antistatic film and the lack of fixing devices, it is easy for the PVC antistatic film to slip and shift during subsequent use, thus reducing the effectiveness of use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an assembly-type PVC antistatic film. By having two sleeves contact the two ends of the PVC antistatic film on the assembly roller, it facilitates the assembly of PVC antistatic films of different sizes. Simultaneously, the arc-shaped pressure plate and arc-shaped sliding pad continuously press against the surface of the PVC antistatic film, preventing edge curling during use. This allows the invention to be adapted to various equipment, making installation convenient and efficient. It also limits the movement of the PVC antistatic film, preventing slippage and improving performance, effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an assembly-type PVC antistatic film, including an assembly roller on the equipment, and the PVC antistatic film is sleeved on the assembly roller;

[0007] The PVC antistatic film is provided with limiting components at both ends, and the limiting components are sleeved on the assembly roller to limit the PVC antistatic film of different sizes.

[0008] The limiting component includes a sleeve, which is fitted onto the assembly roller. An L-shaped fixing rod is fixedly provided on one side of the top of the sleeve.

An arc-shaped sliding pad is fixedly provided at the bottom of the arc-shaped pressure plate, and the arc-shaped sliding pad is in contact with the surface of the PVC antistatic film.

[0009] Preferably, the same telescopic rod is fixed between the inner top of the L-shaped fixing rod and the arc-shaped pressure plate. A spring is sleeved on the telescopic rod. The top and bottom of the spring are fixedly connected to the inner top of the L-shaped fixing rod and the center of the top of the arc-shaped pressure plate, respectively. The other side of the top of the sleeve is connected by a bolt for fixing the assembly roller and the sleeve through a thread, which makes it easy to unscrew the bolt and adjust the distance of the sleeve on the assembly roller, and is suitable for PVC antistatic film of different sizes.

[0010] Preferably, the PVC antistatic film includes a PVC film body, a tensile and scratch-resistant layer is fixedly provided on the top of the PVC film body, an antistatic layer is fixedly provided on the bottom of the PVC film body, a high-temperature resistant layer is fixedly provided on the bottom of the antistatic layer, and the PVC film body, the antistatic layer and the high-temperature resistant layer are fixedly wrapped with the same anti-oxidation layer, which facilitates the anti-oxidation protection of the PVC film body, the tensile and scratch-resistant layer, the antistatic layer and the high-temperature resistant layer.

[0011] Preferably, the tensile and scratch-resistant layer comprises several interleaved coarse and fine glass fiber strips, and several uniformly distributed elastic reinforcing ribs are fixedly provided on the top of the tensile and scratch-resistant layer.

In addition, the polyester in the polyester-cotton blended fibers provides strength, and the cotton fibers enhance moisture absorption, which can strengthen the moisture absorption and auxiliary conductivity of the PVC film body and ensure the antistatic effect of the PVC film body.

[0013] Preferably, the high-temperature resistant layer is composed of polyimide material, which gives the PVC film body excellent radiation resistance, corrosion resistance, high and low temperature resistance, chemical stability, mechanical properties, and dielectric properties. The antioxidant layer is composed of polyester resin material, which has high strength, high toughness, and wear resistance, and also has chemical corrosion resistance, resisting the erosion of chemicals such as acids, alkalis, and salts, ensuring the antioxidant capacity of the PVC film body, and is not easily deformed, thus having an anti-aging effect.

At the same time, under the elastic action of the telescopic rod and spring, the arc-shaped pressure plate and arc-shaped sliding pad continuously press against the surface of the PVC antistatic film, preventing the PVC antistatic film from curling up during use. This makes this utility model adaptable to various equipment, making its installation convenient and efficient.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figures 1-7 As shown, this utility model provides an assembly type PVC antistatic film, including an assembly roller 1 installed on the equipment, and a PVC antistatic film 3 sleeved on the assembly roller 1.

[0030] like Figure 1 , Figure 2As shown, the PVC antistatic film 3 has limiting components 2 at both ends, and the limiting components 2 are sleeved on the assembly roller 1 to limit the PVC antistatic film 3 of different sizes. The limiting component 2 includes a sleeve 21, which is sleeved on the assembly roller 1. An L-shaped fixing rod 22 is fixedly provided on one side of the top of the sleeve 21. An arc-shaped pressure plate 23 is provided at the bottom of the L-shaped fixing rod 22. An arc-shaped sliding pad 24 is fixedly provided at the bottom of the arc-shaped pressure plate 23, and the arc-shaped sliding pad 24 is in contact with the surface of the PVC antistatic film 3. The L-shaped fixing rod 22 has a telescopic rod 25 fixed between its inner top end and the arc-shaped pressure plate 23. A spring 26 is sleeved on the telescopic rod 25. The top and bottom ends of the spring 26 are fixedly connected to the inner top end of the L-shaped fixing rod 22 and the top center of the arc-shaped pressure plate 23, respectively. The other side of the top of the sleeve 21 is connected by a bolt 27 for fixing the assembly roller 1 and the sleeve 21 through a thread. This makes it easy to unscrew the bolt 27 and adjust the distance between the sleeve 21 and the assembly roller 1, which is suitable for PVC antistatic film 3 of different sizes.

[0031] By setting the limiting component 2, the required PVC antistatic film 3 is passed through the assembly roller 1. Then, two sleeves 21 are taken and placed on both ends of the assembly roller 1, so that the sleeves 21 are in contact with both ends of the PVC antistatic film 3. The arc-shaped sliding pads 24 at the bottom of the arc-shaped pressure plate 23 press against the top of both ends of the PVC antistatic film 3. Then, the bolts 27 are tightened to fix the position between the sleeves 21 and the assembly roller 1, so as to facilitate the assembly of PVC antistatic films 3 of different sizes.

[0032] Simultaneously, depending on the thickness of the PVC antistatic film 3 of different sizes, when the arc-shaped sliding pad 24 presses against the surface of the PVC antistatic film 3, it can drive the telescopic rod 25 and the spring 26 to compress. In the subsequent use of the PVC antistatic film 3, the size of the PVC antistatic film 3 decreases, allowing the arc-shaped pressure plate 23 and the arc-shaped sliding pad 24 to continuously press against the surface of the PVC antistatic film 3 under the elastic action of the telescopic rod 25 and the spring 26, preventing the PVC antistatic film 3 from curling up during use. This makes the present invention adaptable to various devices, making its installation convenient and efficient. It can limit the PVC antistatic film 3, prevent the PVC antistatic film 3 from sliding and deviating, and improve the use effect.

[0033] like Figures 3-7As shown, the PVC antistatic film 3 includes a PVC film body 31. A tensile and scratch-resistant layer 32 is fixedly disposed on the top of the PVC film body 31, and an antistatic layer 33 is fixedly disposed on the bottom of the PVC film body 31. A high-temperature resistant layer 34 is fixedly disposed on the bottom of the antistatic layer 33. The PVC film body 31, the antistatic layer 33, and the high-temperature resistant layer 34 are all externally wrapped with the same anti-oxidation layer 35, which facilitates anti-oxidation protection of the PVC film body 31, the tensile and scratch-resistant layer 32, the antistatic layer 33, and the high-temperature resistant layer 34. The tensile and scratch-resistant layer 32 includes several phases. The tensile and scratch-resistant layer 32 has interwoven coarse glass fiber strips 321 and fine glass fiber strips 322. Several evenly distributed elastic reinforcing ribs 323 are fixed on the top of the interwoven coarse glass fiber strips 321 and fine glass fiber strips 322. The woven structure can further improve the toughness of the PVC film body 31, and the glass fiber can act as a high-strength reinforcing skeleton, greatly improving the tensile strength, tear resistance, dimensional stability and durability of the PVC film body 31, while not affecting its core antistatic function.

[0034] The antistatic layer 33 includes several interleaved antistatic synthetic fibers 331 and polyester-cotton blended fibers 332, and the antistatic synthetic fibers 331 and polyester-cotton blended fibers 332 are arranged in a diagonal interleaved pattern to form a continuous conductive mesh structure, ensuring rapid dissipation of charge and improving antistatic stability. In addition, the polyester in the polyester-cotton blended fibers 332 provides strength, and the cotton fibers enhance moisture absorption, which can strengthen the moisture absorption and auxiliary conductivity of the PVC film body 31 and ensure the antistatic effect of the PVC film body 31.

[0035] The high-temperature resistant layer 34 is composed of polyimide material, which gives the PVC film body 31 excellent radiation resistance, corrosion resistance, high and low temperature resistance, chemical stability, mechanical properties, and dielectric properties. The antioxidant layer 35 is composed of polyester resin material, which has high strength, high toughness, wear resistance, etc., and also has chemical corrosion resistance. It can resist the erosion of chemicals such as acids, alkalis, and salts, ensuring the antioxidant capacity of the PVC film body 31, and is not easily deformed, thus having an anti-aging effect.

[0036] By setting a tensile and scratch-resistant layer 32, the elastic reinforcing ribs 323 in the tensile and scratch-resistant layer 32 can improve the strength and flexibility of the PVC film body 31. In addition, the staggered arrangement of coarse glass fiber strips 321 and fine glass fiber strips 322, the woven structure can further improve the toughness of the PVC film body 31, and the glass fiber can act as a high-strength reinforcing skeleton, which can significantly improve the tensile strength, tear resistance, dimensional stability and durability of the PVC film body 31, without affecting its core antistatic function. Combined with the antistatic synthetic fiber 331 in the antistatic layer 33 to form a continuous conductive mesh structure, it can ensure rapid charge dissipation and improve antistatic stability. In addition, the polyester in the polyester-cotton blended fiber 332 provides strength and the cotton fiber enhances moisture absorption, which can strengthen the moisture absorption and auxiliary conductivity of the PVC film body 31, significantly improving the tear resistance, abrasion resistance and dimensional stability of the PVC film body 31. The two work together to form a "conductive-reinforced dual network" that can maintain high reliability of electrostatic protection even in complex environments. Finally, the high-temperature resistant layer 34 and the anti-oxidation layer 35 provide multiple guarantees for the service life of the PVC film body 31, extending its service life.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
