Negative pressure type tight siro spinning machine

Abstract

The invention provides a negative pressure type tight siro spinning machine and belongs to the technical field of spinning. The negative pressure type tight siro spinning machine solves the problems that hair and end-broken strips in a waste cotton collecting box cannot be removed conveniently by an existing negative pressure type tight siro spinning machine, the machine needs to be shut down completely in the removing time, draught fans are stopped, the whole production line cannot work continuously, and consequently the yield is reduced. The negative pressure type tight siro spinning machine comprises a rack, a front roller device, a middle roller device, a rear roller device, a guide wire, a special-shaped pipe device and an air sucking device are arranged on the rack, the air sucking device comprises an air sucking branch pipe communicated with a negative pressure gathering pipe of the special-shaped pipe device, a cotton sucking pipe with a port facing the surface of the front roller assembly, a negative pressure air collecting pipeline connected with the air sucking branch pipe, a cotton sucking and air collecting pipeline communicated with the cotton sucking pipe and a draught fan box. A negative pressure draught fan, a centrifugal draught fan and a cotton removing air pump do not interfere with one another, an operator can remove the hair stored in the waste cotton collecting box at any time, and normal work of the spinning machine is not affected.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a compact spinning machine, in particular to a negative pressure compact siro spinning machine. Background technique [0002] Siro spinning is also called parallel twist spinning, which is called A and B yarn in China, and it is officially named Siro spinning recently. Siro spinning is a spinning method that spins a yarn similar to a strand structure on a traditional ring spinning frame. It feeds two rovings at a certain distance on the spinning frame, and after drafting, it is output by the front roller. These two single yarn strands have a small amount of twist due to the transmission of the twist, and are further twisted into a ply-like yarn after being assembled and wound on the bobbin. [0003] The principle of compact siro spinning is that two rovings are drawn into the drafting area of ​​the spinning frame in parallel, drawn in a parallel state, and come out from the clamp...

AI Technical Summary

Problems solved by technology

[0008] Since the current negative pressure compact siro spinning machine is controlled by two processes separately, it is very inconvenient to clean the hairiness and broken strands in the waste cotton collection box. When cleaning, all must be stopped and the fan stops, so the entire production line It is impossible to continue to work, resulting in a decrease in production capacity
