[0002] With the rapid development of industries such as electronics and machinery, adhesive tape plays a crucial role in the production, packaging, and fixation of products. Especially in the field of battery manufacturing, adhesive tape is widely used to seal the air vents of the battery positive electrode to prevent adverse effects on battery performance caused by components such as carbon dioxide and water vapor in the air.

[0034] In the embodiments of the present utility model, this case provides a tape cutting device for cutting the tape 100 pulled out from the tape body 110, including a base 200, a first translation mechanism 230, a second translation mechanism 240, a clamping mechanism 300, a tensioning mechanism 400, and a cutting mechanism 500. A rotating assembly 700 is provided on the base 200, and the rotating assembly 700 is used for the free rotation of the tape body 110. A fixing frame 210 is provided on the base 200, and one end of the fixing frame 210 is provided with an upward support frame 220.

[0035] Specifically, the adhesive tape body 110 is installed on the rotating assembly 700. The first translation mechanism 230 is started to make the clamping mechanism 300 approach and clamp the adhesive tape 100 and stretch it towards the tensioning mechanism 400. After reaching the cutting position, the adhesive tape 100 on the clamping mechanism 300 slightly protrudes.
