Description

Tail filament shearing mechanism and shearing equipment with same

Technical Field

The utility model relates to the technical field of production of textile chemical fiber filaments, in particular to a tail filament shearing mechanism and shearing equipment with the tail filament shearing mechanism.

Background

At present, chemical fiber filament industry is greatly developed in China, in the production process of the chemical fiber industry, chemical fibers are wound on a paper tube to form a spinning cake, and the spinning cake is wound into a cylinder shape. The last turn of the formed spinning cake cannot be wound tightly and floats and droops to form tail fibers. If the tail fibers are not processed in time, a plurality of potential safety hazards exist in the subsequent production process, and the tail fibers are wound into mechanical equipment to cause equipment failure; affecting the equipment detection signal, causing malfunction and the like.

The existing tail fiber treatment technology mostly adopts a mode of manually shearing or fusing the tail fibers by heating with an electric heating wire. The front end of the doffing equipment is provided with a heating wire mechanism, and the heating wire is made of copper and tin; when the equipment starts to operate, the electric heating wire is preheated to reach the preset temperature, and the tail wire is fused by using high temperature.

For the filaments in chemical fibers in the textile industry, the fusing effect of the heating wire can reach 80%, and the rest parts are manually treated. For industrial yarns in the textile industry, the tail wire fusing technology of an electric heating wire cannot be used, and the manual treatment is mainly used.
