Description

Technical Field

[0001] The utility model specifically relates to the technical field of fine wire processing, in particular to a fine wire winding and unwinding device with a tension regulating function. Background Art

[0002] Fine wire refers to the fine wire material from steel mills, which can also be referred to as fine wire for short. It is generally used for wire rope drawing, radial tires, steel strands and elevator strands, welding wire and small metal parts for daily use.

[0003] During the production and manufacturing process, the fine wire needs to go through multiple steps including stretching, diameter reduction, straightening, etc., and each processing process needs to be carried out using different equipment. Before moving the fine wire to the next processing equipment, the fine wire needs to be reeled up to facilitate the transportation of the fine wire. However, before the fine wire is completely processed, its internal molecular structure has not been completely stabilized. At this time, the fine wire's resistance to deformation and stretching is relatively weak. During the reeling and unreeling process, if the fine wire receives too much tension, the increase in tension on the fine wire surface will cause cracks on the fine wire surface, and even cause dangerous breakage, which not only affects the quality of the fine wire, but also affects the normal progress of the fine wire processing work. Utility Model Content

[0004] The purpose of the utility model is to provide a fine wire winding and unwinding device with a tension adjustment function, which drives the rotating frame to rotate through a cylinder so that the roller on the rotating frame can change its position to change the tension of the fine wire, so as to solve the technical problems raised by the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
