Description

Technical Field

[0001] This utility model belongs to the field of cable production technology, specifically relating to a frame-type stranding machine for cable production. Background Technology

[0002] A stranding machine is a widely used mechanical device for stranding various soft / hard conductor wires. It can tightly strand multiple individual conductors or insulated core wires in a certain order and direction to form a strong and reliable cable, thus twisting multiple single conductors into a single strand to meet the technical requirements of the wire. Stranding machines can generally be classified according to the stranding method into single stranding machines, pair stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tubular stranding machines, and disc stranding machines, as the cables they produce are indispensable media for information transmission and power distribution.

[0003] In existing related technologies, stranding machines are suitable for stranding soft and hard conductor wires. However, current frame stranding machines do not have a limit cutting function during the stranding process. They cannot be quickly cut after the wires are stranded, which affects subsequent work and will affect the product quality after the wires are stranded. Therefore, it is urgent to design a frame stranding machine for cable production to solve these problems. Utility Model Content

[0012] Preferably, the stranded wire exit assembly includes a stranded wire drum disposed at the other end of the bearing rotating shaft, and the stranded wire drum has a stranded wire exit hole.

[0013] The beneficial effects are:

[0014] This utility model discloses a frame-type stranding machine for cable production. Through a limited cutting mechanism, an electric telescopic rod is activated to lift the straightening wheel, straightening the stranded wire produced by the cable stranding mechanism. Simultaneously, an electric cylinder is activated to move the I-beam moving table laterally left and right within the concave platform, causing the straightening wheel to move laterally left and right on the outer surface of the stranded wire to straighten it. A power source is activated to rotate the guide wheel, guiding the straightened stranded wire through the guide wheel. The cutting component is then activated to move downwards until it contacts the cutting plate, cutting the straightened stranded wire. This completes the stranding cutting function. The cutting component returns to its original shape, ensuring the straightening and cutting effect. Secondary guidance and correction by the take-up guide roller achieves rapid cutting of the stranded wire, improving stranding efficiency. It is convenient to use and highly practical.
