A compression spring 14 is fixedly connected, a grounding device 15 is installed at the bottom of the workbench 1, and a grounding channel 16 is fixedly connected to the bottom of the grounding device 15. The grounding device 15 is electrically connected to the first electrostatic block 7, and a support frame 17 is fixedly connected to the bottom of the workbench 1. Two telescopic blocks 18 are fixedly connected to the support frame 17, and a lifting frame 19 is slidably connected to the support frame 17. The lifting frame 19 has clamping holes 20 on both sides. A guide rod 21 is slidably connected inside the grounding channel 16, and a grounding spring 22 is provided on the guide rod 21. A grounding block 23 is fixedly connected to the bottom of the guide rod 21, which can quickly fold up the grounding mechanism when the mobile device is used for easy transfer. At the same time, the first electrostatic block 7 can move according to the diameter of the winding drum and provide a prompt that the winding is completed to improve production efficiency and product quality.
[0021] An extruder 24 is installed on the left side of the top of the workbench 1, and a silo 25 is fixedly connected to the top of the extruder 24. A feed inlet 26 is opened on the top of the silo 25. The extruder 24 melts and extrude the protective film raw material to facilitate subsequent molding.

[0026] The working principle of the static elimination device for protective film production provided by the utility model is as follows:
[0027] When the protective film is produced, it needs to be rolled up. During the rolling process, static electricity will be generated due to the friction between the protective film and the inner wall of the winding device. The static electricity will cause the protective film to easily absorb dust, affect the adhesion of the film, and cause the product quality to decline. When the winding mechanism 2 starts to roll up, the contact block 8 on the first static block 7 will contact the outermost layer of the protective film winding drum, and the static electricity generated by the friction will be conducted from the first static block 7 to the grounding device 15. As time goes by, the diameter of the protective film winding drum will increase, and the contact block 8 will move downward under pressure, and the adaptation spring 10 will be compressed until the contact rod 9 contacts the contact plate 12 to send a signal that the winding is completed. When the production device needs to be moved, it is only necessary to lift the lifting frame 19, and the telescopic block 18 with a built-in spring will be stuck in the card hole 20 on the lifting frame 19, so that the grounding block 23 is temporarily off the ground, which is convenient for the transfer of the device. When the grounding block 23 needs to be put down, it is only necessary to press the telescopic block 18, and the compressed spring 14 will press the lifting frame 19 downward to make the grounding block 23 contact the ground.
[0028] Compared with the related art, the static elimination device for protective film production provided by the utility model has the following beneficial effects:
[0029] By quickly raising and lowering the grounding mechanism, the transfer of the production equipment can be facilitated, the time for equipment installation and disassembly can be reduced, and production efficiency can be improved. The first electrostatic block 7 moves according to the diameter of the winding drum and is always at the outermost edge of the protective film winding. It can immediately receive the static electricity generated by friction during the curling process, which can more effectively eliminate static electricity and improve product quality. The accompanying reminder function when the winding is completed helps to avoid excessive winding or other operating errors and reduce material waste.
