Structurally-modified chemical fiber paper bobbin

Abstract

The invention relates to a structurally-modified chemical fiber paper bobbin comprising a bobbin body. The outer peripheral surface of the top end of the bobbin body is provided with a thread catcher groove comprising a guide groove and a clamp groove. Two sides of an opening of the guide groove are provided with an upper slope and a lower slope respectively. The lower wall of the guide groove intersects the lower slope to form a lower edge. The lower wall of the guide groove and the lower slope incline, recess, and fracture in the lengthwise elongation direction of the lower edge to form a thread hanger part. Through the provision of the upper slope, the lower slope and the thread hanger part, success rate of thread catching is increased, thread guiding frequency is reduced, and efficiency is high.

Description

technical field [0001] The invention relates to a chemical fiber paper roll, in particular to an improved structure of the chemical fiber paper roll. Background technique [0002] During the winding process of chemical fiber filaments, special chemical fiber paper tubes are usually used to guide the thread ends of chemical fiber filaments from the winding machine to the chemical fiber paper tubes. In order to make the chemical fiber paper cylinder catch the chemical fiber filaments conveniently, the chemical fiber paper cylinder in the prior art usually has a silk catching groove on the outer surface of one end circumference. Groove and narrow wire clamping groove, however, the use effect of this conventional wire catching groove structure is not ideal, and chemical fiber often cannot enter the wire drawing groove smoothly, which usually requires multiple wire drawing in the process of use. The chemical fiber filaments are captured smoothly, but the efficiency is low. Con...
