Description

Technical Field

[0002] The wire cutting machine is an electronic product. It can store 100 sets of data and has six cutting and stripping modes, allowing for instant adjustment. It's a new energy source, a complete power system, and is designed specifically for meter boxes. The automatic wire cutting machine uses a PLC to control two stepper motors: one drives two conveyor wheels to transport the wire, and the other rotates the wire trough, allowing the finished product in the trough to be dumped into the finished product trough below. The cutting process is powered by an air pump, and the PLC controls the solenoid valve to power the cylinder, forcing it to press down and cut.

[0003] At present, when cutting wires, the wire cutting machine does not position the cutting wire harness, which causes the wire harness to shift during the cutting process. As a result, the cutting cut and the cutting length do not meet expectations, affecting the cutting effect of the wire cutting machine. At the same time, since the current cutting scissor frame cannot be moved, it is not convenient to cut wire harnesses of different lengths.

[0004] Therefore, a wire cutting machine tool holder is proposed. Utility Model Content
