BRIEF DESCRIPTION OF DRAWINGS

[0017] In order to more clearly illustrate the technical scheme of the embodiment of the utility model, the following will briefly introduce the drawings needed to be used in the embodiment.

[0018] Figure 1 The structure of the multi-layer protective film structure in an embodiment of the utility model is shown in the figure.

[0019] Reference signs:

[0020] Membrane layer 10, handle 11, vacuum hole 12, release film 20. DETAILED DESCRIPTION

[0021] In order to facilitate understanding of the utility model, the following will be more comprehensive description of the utility model with reference to the relevant drawings.

[0022] The application proposes a multi-layer protective film structure, please refer to Figure 1 , including: membrane layer 10, the membrane layer 10 includes at least two layers of protective films, each layer of protective film includes opposite first face and second face, the surface of second face is provided with adhesive layer, the adhesive layer of the second face of the upper layer of protective film is bonded with the first face of the lower layer of protective film, so that each protective film is sequentially stacked, and the edges of each layer of protective film are aligned, which facilitates the overall placement of the multi-layer protective film structure on the silk screen platform. The multi-layer protective film structure of the utility model has multiple protective films, after a certain time of silk screen, one layer of protective film can be torn off, without the need to place the protective film on the silk screen platform, reducing the action of employee operation, reducing the work intensity, improving the protective film replacement speed, thereby improving the production efficiency.

[0023] Please refer to Figure 1A handle 11 is arranged on each protective film, which can facilitate the worker to tear off the protective film, reduce the use of adhesive film paper, and reduce the cost.

[0024] Preferably, the handle 11 has different colors, which further facilitates the worker to identify the protective film, avoids tearing by mistake, reduces material waste.

[0025] In an embodiment, the multi-layer protective film structure further comprises a release film 20 arranged on the surface of the film layer 10 having a glue layer at the bottom, which protects the glue layer at the bottom of the protective film from being polluted and avoids affecting the adhesion. The release film needs to be torn off before the film layer is used, and the film layer is attached to the silk screen platform through the glue layer.

[0026] Further, the release film 20 is a heavy release film 20, which has high hardness and can better support the film layer 10 to prevent the film layer 10 from bending. The length of the release film 20 is greater than the length of the film layer 10, and the width of the release film 20 is greater than the width of the film layer 10.

[0027] Still further, a through hole is arranged on the silk screen platform, which is communicated with a suction device, which can quickly suck the air in the through hole to form a negative pressure.
