Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink film production, in particular to a cutting device for heat shrink film production. Background Art

[0002] Polymer lithium-ion soft-pack batteries have been widely used in recent years due to their flexible shape and size, fast charging speed, excellent cycle characteristics, high operating voltage, high specific energy, large capacity, and environmental friendliness. Generally, the outside of polymer lithium-ion soft-pack batteries is packaged with heat shrink film. The heat shrink film shrinks when heated and tightly wraps around the outer surface of the battery. The heat shrink film is generally made of PVC material.

[0003] According to the search, Chinese patent literature, announcement number: CN218476751U, discloses a heat shrink film cutting device, which can drive the first cutter to move up and down through the cutting drive member. When the first cutter moves downward, it can cooperate with the second cutter to cut off the free end of the heat shrink film material. Through the telescopic action of the adjustment rod, the length of the adjustment rod becomes longer or shorter, so that the mounting frame can be rotated around the vertical axis, and the mounting frame drives the first cutter and the second cutter to rotate. There is a certain angle between the first cutter and the second cutter and the transverse direction of the heat shrink film, and the first cutter and the second cutter can cut chamfers at the free end of the heat shrink film material. The chamfer angle of the cutting chamfer can be adjusted by adjusting the telescopic length of the adjustment rod. The utility model can cut heat shrink film products with different chamfer angles from the heat shrink film material, and has a wide range of applications and high versatility. However, during use, since the roll is a snap-fit ​​installation structure, it is easy for the roll to shift to the left or right when pulling the heat shrink film, which can easily affect the cutting accuracy during the cutting process and cause inconsistent incision sizes. In addition, during use, since the position between the two sets of rollers is fixed, it is more troublesome for the heat shrink film to pass through the rollers, and a lot of time is needed to organize the heat shrink film. In addition, the length of the heat shrink film cannot be judged during use, which requires later measurement, and its use is more limited. Utility Model Content
