Description

Technical Field

[0001] This utility model relates to the technical field of protective films, and more particularly to an antistatic protective film. Background Technology

[0002] In terms of function, a protective film is to put a layer of film on the physical object we want to protect. Its main function is to prevent the substrate from being scratched, contaminated by dust or chemically corroded during transportation, processing or daily use.

[0003] During the process of covering materials with a protective film, friction occurs between the film and the surface of the covered material, as well as other objects in contact with it. Because different materials have varying abilities to bind electrons to atoms, electrons transfer from the surface of the material with weaker binding to the surface of the material with stronger binding during friction, causing the two materials to acquire positive and negative charges respectively, thus generating static electricity. This static electricity causes the protective film surface to become charged, attracting surrounding dust, hair, and other tiny impurities. Furthermore, when covering flammable objects, the sparks generated by electrostatic discharge may ignite a fire. Therefore, when covering flammable objects, workers often choose protective films with anti-static materials. However, this only prevents the protective film from generating static electricity; it cannot discharge the static electricity generated during friction. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose an antistatic protective film. In the manufacturing stage of the protective film, a conductive fiber mesh is combined with the protective film substrate, thereby transferring static electricity to the wire through the conductive fiber mesh, and then conducting it to the ground through the wire, effectively avoiding the risk of dust adsorption and fire caused by static electricity.

[0006] To achieve the above objectives, the first aspect of this utility model provides an antistatic protective film, comprising: a protective film and a conductive mechanism, wherein the conductive mechanism includes a fiber mesh, multiple metal sheets, four connecting rings, four wires, and four grounding blocks. The fiber mesh is disposed on the bottom wall of the protective film; the multiple metal sheets are respectively disposed on the bottom wall of the fiber mesh; the four connecting rings respectively penetrate through the four corners of the fiber mesh and are respectively connected to the four corners of the fiber mesh; the four wires are respectively connected to the corresponding connecting rings; and the four grounding blocks are respectively connected to the other end of the corresponding wires.

[0007] In addition, the antistatic protective film proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, a protective membrane is provided on the bottom wall of the protective membrane, and a fiber mesh is placed between the protective membrane and the protective membrane, with multiple metal sheets penetrating through the protective membrane.

[0009] Specifically, the outer wall of the protective film and the protective film is provided with a tightening component, wherein the tightening component includes a through strip and an elastic band, wherein the through strip is provided on the outer wall of the protective film and the protective film; the tightening component passes through the through strip.

[0010] Compared with the prior art, the present invention has the following advantages: In the protective film manufacturing stage, the conductive fiber mesh is combined with the protective film substrate, so that static electricity is transferred to the wire through the conductive fiber mesh, and then conducted to the ground through the wire, effectively avoiding the risk of dust adsorption and fire caused by static electricity.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The antistatic protective film of this utility model embodiment is described below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown, the antistatic protective film of this utility model embodiment includes: a protective film 1 and a conductive mechanism 2.

[0021] The conductive mechanism 2 includes a fiber mesh 21, multiple metal sheets 22, four connecting rings 23, four wires 24, and four grounding blocks 25.

[0022] The fiber mesh 21 is set on the bottom wall of the protective film 1, and multiple metal sheets 22 are respectively set on the bottom wall of the fiber mesh 21. Four connecting rings 23 pass through the four corners of the fiber mesh 21 and are respectively connected to the four corners of the fiber mesh 21. Four wires 24 are respectively connected to the corresponding connecting rings 23, and four grounding blocks 25 are respectively connected to the other end of the corresponding wires 24.

[0023] It should be noted that the fiber mesh 21 described in this embodiment is made of metal fiber. Because metal has good conductivity, static electricity is transferred. The metal sheet 22 described in this embodiment is made of soft material, so it does not affect the coverage of the material by the protective film 1.

[0024] Specifically, after the material is covered with the protective film 1, the staff needs to connect the grounding block 25 to the ground. At this time, the static electricity generated will be transferred to the fiber mesh 21 through the metal sheet 22, and then transferred to the wire 24 through the fiber mesh 21. The wire 24 will release the static electricity to the ground through the grounding block 25.

[0025] In one embodiment of this application, such as Figure 4 As shown, a protective membrane 4 is provided on the bottom wall of the protective membrane 1, and a fiber mesh 21 is provided between the protective membrane 1 and the protective membrane 4. Multiple metal sheets 22 penetrate the protective membrane 4 respectively.

[0026] It should be noted that the protective film 4 described in this embodiment is made of polyethylene terephthalate, an antistatic material.

[0027] It is understandable that by placing the fiber mesh 21 between the protective film 1 and the protective film 4, the protective film 4 can prevent the static electricity on the fiber mesh 21 from being retransmitted to the covered material.

[0028] In one embodiment of this application, such as Figure 1 and Figure 3 As shown, the outer walls of the protective film 1 and the protective film 4 are provided with a tightening assembly 3.

[0029] The tightening component 3 includes a through strap 31 and an elastic band 32.

[0030] The penetrating strip 31 is disposed on the outer wall of the protective film 1 and the protective film 4, and the tightening component 3 passes through the penetrating strip 31.

[0031] Specifically, after covering the material, when it is necessary to fix the protective film 1 to the outside of the covered object, the staff can pull the elastic band 32 inside the through-belt 31. At this time, the elastic band 32 will tighten the edge of the protective film 1, thereby fixing the protective film 1 to the outside of the covered object.

[0032] In summary, during the protective film manufacturing stage, the conductive fiber mesh is combined with the protective film substrate, thereby transferring static electricity to the wires through the conductive fiber mesh, and then conducting it to the ground through the wires, effectively avoiding the risk of dust adsorption and fire caused by static electricity.
