Description

Technical Field

[0001] The utility model relates to the field of wire cutting devices, and more specifically, to a fixed-length wire cutting device. Background Art

[0002] The fixed-length slitting device can ensure the consistency of the length of the slitting and improve product quality through the precise fixed-length control part. Compared with manual slitting, this device can achieve continuous and rapid cutting. In some industrial raw material processing fields, such as the cutting of plastic pipes, metal wires and other materials, devices based on similar principles can also be used to cut the materials into fixed-length filaments for subsequent packaging and use.

[0003] When the blade of the fixed-length wire cutting device becomes blunt, the cutting surface will become rough. For some industrial materials that require high wire cutting precision, such as metal wire or other materials used in industrial equipment, the blunt blade will cause the wire diameter to be uneven. Therefore, it is necessary to design a fixed-length wire cutting device with auxiliary sharpening to solve the above problem. Utility Model Content
