Background Art

In the communication, electrical and other industries, it is often necessary to cut cables. In the production of the same electrical equipment, many wires of the same length are required. If these wires are cut manually, the efficiency is low and the cost is high, so a wire cutter is used. The wire cutter is a special equipment used to press and cut various ordinary cardboards, corrugated cardboards, plastic sheets, leather products, lines, etc. It has a compact structure, excellent manufacturing, and safe and reliable operation.

The existing wire cutting machine has a relatively simple function when in use, and there is no quick correction system. It can only cut the lines. It cannot be quickly corrected during the cutting process, and the lines cannot be quickly straightened. The material of the lines themselves is relatively soft, and they will naturally droop or misalign during the cutting process, which may affect the consistency of the cutting length of the lines, reduce the accuracy, and is not conducive to improving work efficiency. The intelligent equipment cannot be realized, and the lines need to be positioned and transmitted before cutting. When positioning the lines, the existing wire cutting machine passes the wire heads through the positioning holes. This operation is troublesome, time-consuming, and labor-intensive, and is inconvenient for the staff to operate. In addition, in the process of transmitting the lines, the friction between the angle between the lines and the positioning blocks may be large due to the different conveying angles and heights, causing wear on the lines, thereby affecting the cutting quality.
