Description

Technical Field

[0001] This utility model relates to the field of wire and cable equipment, specifically a vertical untwisting machine for small wire reels. Background Technology

[0002] The untwisting machine is a key piece of equipment in the wire and cable manufacturing process. It is mainly used to twist multiple single wires (such as copper wire, aluminum wire, etc.) into strands according to certain rules to improve the flexibility, mechanical strength, and electrical performance of the cable. The stranding process is widely used in the production of power cables, communication cables, data cables, and special cables.

[0003] Wires and cables are made by twisting together multiple thin wires. The untwisting machine is the front-end equipment in the cable manufacturing process. Most untwisting machines in the current technology are horizontal or cage-type. In particular, untwisting machines for small wire reels are now mostly cage-type structures. The existing structure results in a high center of gravity for the whole machine and cannot integrate the tensioner. During operation, the vibration is large and the tension of the wire cannot be uniformly controlled, which affects the quality of the produced wires and cables. Moreover, the high center of gravity also results in a high distance between the loaded wire reels and the ground, making the loading of the wire reels more laborious and difficult. Summary of the Invention

[0004] (a) Technical problems to be solved.

[0005] To address the shortcomings of existing technologies, this utility model provides a vertical untwisting machine for small wire reels, which solves the problems of low wire quality, inconvenient and laborious reel loading mentioned in the background art.

[0017] (iii) Beneficial effects.

[0018] This utility model provides a vertical untwisting machine for small wire reels, which has the following beneficial effects: 1. The untwisting and unwinding mechanism is arranged vertically, which solves the problem that the traditional structure has a high center of gravity of the wire reel, resulting in low rotation speed and large vibration, which affects the quality of the wire. The vertical structure has a low center of gravity of the wire reel, which increases the rotation speed of the wire reel and reduces vibration, thereby improving the quality of the wire and production efficiency.

[0019] 2. The untwisting machine integrates the tensioner assembly and the tension sensing anti-breakage mechanism assembly into the untwisting machine. This allows the control program of the untwisting machine to simultaneously control the speed of the untwisting machine, the tensioner, and the tensioner sensing anti-breakage assembly to work in coordination. At its highest level, it can achieve 100% untwisting and overcomes problems such as the quality degradation of the wire due to uneven torque, thus significantly improving the quality of the wire.
