Independent special-shaped tube negative pressure type compact spinning apparatus

Abstract

The invention provides a compact spinning device, particularly an independent special pipe subpressure type compact spinning device which solves problems that the prior compact spinning device occurs axial play and radial variation easily during running, and a tearing phenomenon between a delivery roller with gear and the subpressure aspiration pipe. The independent special pipe subpressure type compact spinning device includes a roller stand, a front roller with gear, the delivery roller with gear; the special pipe is set between the front roller and the delivery roller; a subpressure aspiration system is in the special pipe, two ends of the special pipe are fixed on two sides roller stand respectively, the delivery roller and the special pipe set a net ring altogether on corresponding each spindle position. The independent special pipe subpressure type compact spinning device has merits that: 1. the special pipe and the delivery roller are installed on the roller stand comparatively independent that are not easy to tearing; 2. relative position of the special pipe and the delivery roller are not changed in running state ensured by a locating block for ensuring no departure when the drafted fibre beam passes through an air suction groove in the special pipe.

Description

technical field [0001] The invention belongs to a compact spinning device, in particular to an independent special-shaped tube negative pressure compact spinning device. Background technique [0002] There are some deficiencies in the spinning mechanism of the traditional ring spinning frame. On the ring spinning frame, the section of the roving becomes flat and mustered after being pressurized and drawn by three pairs of rollers, and it needs to be twisted into a circular yarn. , where the spinning triangle is formed. When twisting, the fibers at both ends of the flat whisker in the spinning triangle area are seriously transferred from inside to outside, and some fibers are thrown out of the yarn body to form hairiness of different lengths. Due to the existence of the spinning triangle area, the fibers form different lengths of hairiness during twisting. The tension is inconsistent, so that the overall tension of the yarn is lower than the sum of the tensions of each fiber...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the existing compact spinning device is prone to longitudinal movement and radial change during operation, and at the same time it is easy to collect flowers between the output roller with gear and the negative pressure suction pipe, it provides an independent special-shaped Tube negative pressure compact spinning device
