A vibrating plate used in vibrating cotton feeder for hemp fiber spinning

Abstract

A vibrating disk used for a vibrating cotton feeder for hemp fiber spinning, comprising a vibrating disk body (5) and a striking point (6) arranged on the working surface (7) of the vibrating disk body (5), the striking The number of points (6) is 2-4, and the frequency at which the striking points (6) hit the vibrating plate (3) is 20-180 times per minute. The vibrating plate body of the vibrating cotton feeder for hemp fiber spinning of the present invention has fewer striking points, so that the frequency of the vibrating plate is reduced, the amplitude is larger, and the striking force of the hemp fiber is greater, making the relatively thick and hard The gap between the hemp fibers is reduced, which effectively improves the uniformity of the roll.

Description

technical field [0001] The invention relates to a vibrating disk for a vibrating cotton feeder, in particular to a vibrating disk for a vibrating cotton feeding machine for spinning hemp fiber, especially jute or hemp fiber. Background technique [0002] In the process of opening and cleaning cotton fiber, chemical fiber and other fibers between spinning, it is necessary to vibrate the fiber through the vibrating cotton feeder to form a cotton layer with uniform density, so as to form a uniform cotton lap through the lapping machine. Used in the subsequent spinning process. But existing vibrating cotton feeding machines are all designed for cotton fiber or chemical fiber spinning, and the vibrating plate of vibrating cotton feeding machine is usually provided with five hit points, and under the normal rotating speed, the frequency of the hitting vibrating plate hit by the hit points It is about 200 times / minute, the vibration frequency is fast, the amplitude of the vibratio...

AI Technical Summary

Problems solved by technology

But hemp fiber, especially jute or hemp fiber is thicker and harder than cotton fiber or chemical fiber. The blow force is too small, so that the gap between the hemp fibers after the vibrating cotton feeder is relatively large, which affects the uniformity of the roll (when the jute fiber uses the existing vibrating cotton feeder, the roll uniformity is about 1.3%) about)
