Coarse spinner

Abstract

The invention relates to a coarse spinner. The coarse spinner comprises a rack, a cleaning recycling structure, and a yarn placing mechanism, a drafting mechanism and a twisting mechanism which are arranged in the forward motion direction of yarns from backwards to forwards in sequence, wherein the drafting mechanism comprises three drive rollers and three driven rollers, and the three driven rollers are arranged in front of the three drive rollers in a one-to-one correspondence manner; the cleaning recycling mechanism comprises an upper air bellow, a lower air bellow, a ventilation pipe, a recycling box and an air suction mechanism; the upper air bellow and the lower air bellow are arranged above and below the drafting mechanism respectively; a plurality of air suction ports are formed inthe lower end of the upper air bellow and the upper end of the lower air bellow respectively; scrapers are arranged on the edges of the sides of the air suction ports; knife edges of the scrapers extend towards the drive rollers or the driven rollers; the upper air bellow and the lower air below are connected and communicated with one end of the ventilation pipe respectively; one end of the recycling box is connected and communicated with the other end of the ventilation pipe, and the other end of the recycling box is connected and communicated with an air outlet of the air suction mechanism.According to the coarse spinner, short fibers and broken fabrics are prevented from being accumulated on the drafting mechanism, so that the quality of the yarns is improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a roving frame. Background technique [0002] The roving frame is a spinning machine that makes fiber sliver into roving. Its main function is drafting and twisting, and winding the roving into a certain package to meet the processing requirements of the spinning frame. During the drafting process, the drafting The surface of the mechanism will have broken wadding. When too much wadding is attached to the surface of the drafting mechanism, it will cause broken wadding on the surface of the polymerized sliver, which will affect the cleanliness and smoothness of the sliver surface and reduce the quality of production. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roving frame that can automatically remove short piles and broken wadding. [0004] The technical solution of the present invention to solve the above...
