A cutting mechanism is installed above the material receiving mechanism. The structure is simple and the structure is clear and easy to understand. The waste pipe is resisted by a safety baffle to control the output speed of the waste pipe, which can ensure the cutting time and length of the strip, cut it in place at a constant time, control the cutting consistency of the product crimping strip, and ensure safety.

[0003] After the cutting knife of the above-mentioned cutting mechanism cuts off the waste tube, the cut waste tube falls into the waste box and is collected.
