AI Technical Summary
Existing automotive wiring harness cutters can only feed single wire harnesses, resulting in low cutting efficiency. Furthermore, the high friction between the wire harness feed components and the wire harness can easily cause wear.
A wire cutter was designed, comprising a base plate, a support plate, a fixing rod, a guide rod, a fixing frame, a wire distribution tube, a conveying wheel, and a motor. The conveying assembly, consisting of multiple sets of guide rods and conveying wheels, uses a motor-driven gear to rotate the shaft and conveying wheel, enabling the parallel conveying of multiple wire harnesses. The wire reel is fixed by the fixing rod and pressure plate, reducing the friction between the wire harness and the rotating wheel.
It enables efficient transport and cutting of multiple wire harnesses, reduces wire harness wear, improves cutting efficiency, and prevents damage to wire harnesses caused by friction during transport.
