[0003] The existing shielding film production and pressing equipment still has certain shortcomings in actual use: the existing shielding film pressing equipment lacks a positioning and calibration structure for multiple raw material films when in use, resulting in uneven pressing of the shielding film and quality problems. Based on the existing technical deficiencies, the utility model designs a shielding film production and pressing tooling. Utility Model Content

[0010] As a preferred technical solution of the present invention, the hot pressing roller of the first hot pressing machine can be stuck in the pressing groove.

[0011] As a preferred technical solution of the present invention, the four fixing bolts are threadedly connected to the workbench.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The shielding film production pressing tooling uses a calibration structure. When pressing and forming three kinds of shielding film raw materials, the three raw materials are overlapped and inserted into the inner groove. At this time, the two threaded rods on the left are rotated to make the two mounting frames drive the pressing rollers to move downward on the limit rods, so that the pressing rollers can gently press the raw materials. At this time, one end of the three raw materials is pressed by the first hot press. Then, the film is passed through the two pressing rollers on the right from below and is gently pressed against the raw materials. At this time, the head of the raw material film is passed through the second hot press, and is gently pulled by hand. At the same time, the second hot press performs hot pressing. After reaching a certain length, the pressed shielding film is wound on the winding roller. This structure avoids the uneven direct contact of the raw materials caused by traditional direct pressing by first hot pressing one end of the head of the three raw materials and then pressing the whole.

[0014] 2. This shielding film production pressing tool uses a support frame to insert the three raw film materials into the three gaps between the four brush rollers before inserting them into the inner groove. The brush roller can brush off the dust on the surface of the raw film by winding and pulling the winding roller, thereby improving the quality of the device pressing.
