[0002] The insulating protective film is a thin film material that has excellent electrical insulation properties to ensure that current will not leak or short-circuit through it. In high-frequency insulation applications, the requirements for insulating protective films are more stringent.

[0003] At present, coating machines and coatings play an important role in the processing and production of power battery insulation protective film. As a key equipment, the coating machine is responsible for evenly coating the coating on the surface of the insulation protective film. The selection of coating is also crucial.

Through the arrangement of the pump 6, the feed pipe 7 and the discharge pipe 8, it is convenient to increase the paint in the storage tank 5 to improve the flow efficiency, and it is convenient to supply paint to the sprayer 4.

[0029] The inner side of the storage tank 5 is equipped with a stirring mechanism, which is used to stir the coating raw material.

[0030] The stirring mechanism includes a mounting bracket 9, a driving motor 10, a first gear 11, a force transmission gear ring 12, an inner rotating rod 13 and a stirring bracket 14. The mounting bracket 9 is fixed to the outside of the storage tank 5, and the driving motor 10 is fixed to the top of the mounting bracket 9. The output end of the driving motor 10 passes through the mounting bracket 9 and is fixed with a first gear 11. The outer side of the first gear 11 is meshed and connected with the force transmission gear ring 12. The force transmission gear ring 12 is rotatably connected to the top of the storage tank 5. Both ends of the bottom of the force transmission gear ring 12 are equipped with inner rotating rods 13, and multiple stirring brackets 14 are evenly fixed on the outer side of the inner rotating rod 13.

Vertical plates are fixed to both ends of the inner bottom of the rotating concave disc 15, and a force-applying motor 16 is fixed to one side of the vertical plate. The output end of the force-applying motor 16 passes through the vertical plate and is fixed with a second gear 17. The top of the second gear 17 is meshed and connected with the top toothed disc 18.

[0035] From the above, we can know that:

[0036] The utility model is aimed at the technical problem that the existing technology can realize the coating process of the insulating protective film during use, but during processing, since the coating is usually temporarily stored in the storage tank, once the coating machine is processed for a long time, the coating in the storage tank is prone to precipitation, thereby affecting the product quality when producing and processing the insulating protective film; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0037] During use, first, add a proper amount of coating raw materials into the storage tank 5 through the feeding port, then start the driving motor 10 and the force motor 16, so that the output end of the driving motor 10 drives the first gear 11 to engage the force transmission gear ring 12 to rotate, because the force transmission gear ring 12 is fixed to the rotating concave disk 15, the rotating concave disk 15 can drive the inner rotating rod 13 and the stirring bracket 14 to rotate synchronously, and the coating raw materials are turned over and stirred. At the same time, the output end of the force motor 16 drives the second gear 17 to rotate, because the second gear 17 is engaged and connected with the top toothed disk 18 and the bottom toothed disk 20, the top toothed disk 18 is fixed to the inner rotating rod 13, the bottom toothed disk 20 is fixed to the rotating sleeve rod 19, and the rotating sleeve rod 19 is rotatably connected to the inner rotating rod 13, so the inner rotating rod 13 and the rotating sleeve rod 19 can be coaxially rotated in the opposite directions, so as to achieve re-stirring of the coating raw materials, improve the stirring efficiency, and make the coating raw materials mixed more evenly;

[0038] Then start the pump 6 and the sprayer 4. The input end of the pump 6 transfers the paint in the storage tank 5 to the discharge pipe 8 through the feed pipe 7. Finally, the discharge pipe 8 supplies the paint to the sprayer 4, so that the sprayer 4 can coat the insulating protective film on the coating table 1.
