Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing equipment technology, specifically to a lifting, unwinding, and untwisting machine for various types of wire reels. Background Technology

[0002] Wire and cable stranding machines are key pieces of equipment in the wire and cable manufacturing process. They are mainly used to strand multiple single wires (such as copper wires, aluminum wires, etc.) into strands according to certain rules to improve the flexibility, mechanical strength, and electrical performance of the cable. Stranding technology 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 a front-end device in the wire and cable manufacturing process. In the existing technology, Chinese patent number 2013200454700, announcement number CN203134470U, patent name active untwisting constant force wire release machine, discloses an untwisting wire release machine that can be used with a stranding machine. However, in actual production, the wire spools need to be placed on the untwisting machine manually, and one untwisting machine can only adapt to one type of wire spool. Generally, the weight of the wire spools is over 500KG, so multiple people are needed to operate it. Moreover, accidents can easily cause serious accidents with injuries or fatalities. In addition, one untwisting machine can only adapt to one type of wire spool, which greatly increases the procurement cost of wire and cable manufacturers. Summary of the Invention
