Description

Technical Field

[0001] The present invention relates to the technical field related to tape cutting devices, in particular to a transmission shaft of a tape cutting machine. Background Art

[0002] Automatic tape cutters are widely used across various industries, enabling both fixed-length and automatic tape cutting. A motor drives a drive shaft, which, through gears, drives a conveyor shaft to convey the tape forward. At the tape outlet, a steel shaft with a rubber ring overlays the elasticity of the ring, preventing the tape from tangling and transporting it forward to the cutting edge.

[0003] However, most of the tapes currently used for cutting on the market are ordinary transparent tapes, which are generally 38-53 microns thick and have low viscosity, and do not have high requirements for cutting machines. For tapes used in some special industries, the thickness of the tapes reaches 80 microns and the viscosity is higher, which causes greater wear and tear on the rubber rings on the cutting machines. On average, they need to be replaced every three days. At the same time, there is a risk of tape entanglement, resulting in tape waste. Summary of the Invention
