Description

Technical Field

[0001] The utility model relates to the technical field of anti-twisting, in particular to a flat wire anti-twisting device. Background Art

[0002] At present, the flat wire produced by the extruder is a common type of power cord. During the production process of the flat wire, the wires need to be arranged in a certain twisting direction or a guide strip needs to be added. However, due to employee misoperation, the wires inside the flat wire may become twisted, resulting in unqualified flat wires.

[0003] After searching, a new type of device for preventing the twisting of wires drawn by an automatic cutting machine is found with publication number CN217432892U, which includes an outer frame and a clamping structure. The clamping structure is arranged on both sides of the inner part of the outer frame. The outer frame includes a bottom frame and an upper frame. The contact surfaces of the upper frame and the bottom frame are provided with perforations, and the perforations are provided with grooves. A rotating structure is arranged in the groove. The rotating structure includes a bracket, a rotating wheel, a base frame, a pressure plate and a spring. The middle part of the rotating wheel is movably arranged on the bracket, and the bottom end of the bracket passes through the base frame and is fixed to the top end of the pressure plate.
