Embodiment 1

[0050] The embodiment of the present invention provides a self-adhesive PE protective film, such as Figure 1-Figure 6 As shown, it includes: a protective film body 1, a casing 2 and a sticking assembly, a fixing assembly is arranged in the casing 2, and the protective film body 1 is installed in the casing 2 through the fixing assembly, and the casing 2. A through hole 3 is provided on the upper surface, the upper side of the protective film body 1 extends through the through hole 3 to the outside of the casing 2, and the application component is located directly above the protective film body 1.

[0051] The working principle and beneficial effects of the above technical solutions are as follows: a self-adhesive PE protective film provided by the present invention includes a protective film body 1, a casing 2 and an application component, a protective film body 1, a casing 2 and an application The three components are used together. The protective film body 1 is arranged in ...

Embodiment 2

[0053] On the basis of the above Example 1, as Figure 1-Figure 4 As shown, the protective film body 1 is made of a three-layer co-extrusion blown film of a self-adhesive layer 5, an intermediate layer 6 and a protective layer 7, and the intermediate layer 6 is located between the protective layer 7 and the self-adhesive layer 5. between;

[0054] The self-adhesive layer 5 includes metallocene polyethylene, the intermediate layer 6 includes low density polyethylene, and the protective layer 7 includes polypropylene resin and low density polyethylene;

[0055] The fixed assembly includes:

[0056] Two first sliding grooves 8, the two first sliding grooves 8 are symmetrically arranged on the inner walls of the left and right sides of the casing 2;

[0057] The first slide rail 9, the inner walls of the two first slide grooves 8 are respectively provided with a first slide rail 9, the first slide rail 9 is arranged vertically, and the side wall of the first slide rail 9 is conn...

Embodiment 3

[0065] On the basis of Example 2, as figure 1 , Figure 4 As shown, a first electric telescopic rod 18 is arranged below the first slider 10, one end of the first electric telescopic rod 18 is fixedly connected to the inner wall of the bottom of the housing 2, and the other end of the first electric telescopic rod 18 is connected to the bottom inner wall of the housing 2. The lower surface of the first slider 10 is fixedly connected.

[0066] The working principle and beneficial effects of the above technical solutions are: with the use of the protective film body 1, the thickness of the protective film body 1 wound on the film roll 16 is gradually reduced, in order to ensure that the protective film body 1 always exceeds the upper end of the through hole 3. Height, a first electric telescopic rod 18 is arranged under the first slider 10. When the actual height of the protective film body 1 beyond the through hole 3 is lower than the preset height, the first electric telescop...

Abstract

The invention provides a self-adhesive PE protective film which comprises a protective film body, a shell and an adhesive component, a fixing component is arranged in the shell, the protective film body is mounted in the shell through the fixing component, a through hole is formed in the upper surface of the shell, the upper side of the protective film body penetrates through the through hole and extends to the outside of the shell, and the adhesive component is arranged in the protective film body. The pasting assembly is located over the protective film body. According to the protective film, the protective film body is arranged in the shell, the protective film body is protected, the protective film can be fixed through the fixing assembly, during use, when a protected product passes through the protective film body, the pasting assembly and the protective film body can extrude the protected product at the same time, and the protective film body is pasted on the lower surface of the protected product; through downward pressing of the pasting assembly, the protective film body is pasted firmly, the pasting effect is improved, the problems of warping, falling off and the like are not prone to occurring in the using process, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a self-adhesive PE protective film. Background technique [0002] PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. PE protective film is based on special polyethylene (PE) plastic film, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. [0003] The biggest advantage of PE protective film is that the protected product will not be polluted, corroded, scratched during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, thereby improving product quality and market competitiveness. . [0004] When using the PE protective film, it is necessary to manually paste the protective film on the protected product. During the pasting process, in order to ...
