Description
Technical Field
[0001] The utility model relates to the technical field of wire production devices, in particular to a wire pay-off device for flat copper wire production. Background Art
[0002] In the production of flat copper wire, it is necessary to perform multiple winding and unwinding operations on the semi-finished wire. Currently, unwinding is mostly performed by unwinding equipment driven by a motor. The existing equipment has the following problems: 1. It is necessary to switch between wire reels of different sizes during use, and the existing equipment often cannot conveniently fix wire reels of different sizes; 2. The existing unwinding equipment often uses a gravity-based tensioning device, which has a simple structure but cannot adjust the working speed of the unwinding motor. There are also devices that provide feedback adjustment to the unwinding motor based on the wire output situation, but the debugging process is generally complicated and ordinary workers on site often cannot master it well; 3. For flat copper wire, when the unwinding speed is too fast, the flat copper wire can be twisted before the tensioning structure reacts. This twisting can easily cause the wire to deform and affect the quality of the wire. Utility Model Content
