Nozzle rotating device of air jet spinning machine

Abstract

The invention discloses a nozzle rotating device of an air-jet spinning machine, particularly relates to the technical field of air-jet spinning machines, and aims to solve the problems that the nozzle adjusting angle of a traditional air-jet spinning machine is not accurate enough, and the nozzle is inconvenient to maintain and replace. The nozzle rotating device comprises a fixing plate, symmetrical limiting wheels are slidably arranged on the fixing plate, and a rotating column is installed at one end of each limiting wheel; a rectangular block is installed at the end, away from the limiting wheel, of the rotating column, a clamping mechanism is installed at one end of the rectangular block and comprises a first buckle and a second buckle, a hook is installed at one end of the second buckle, a third screw is installed at one end of the first buckle, and a nozzle body is clamped between the first buckle and the second buckle. A first buckle and a second buckle are used for clamping and fixing a nozzle body, a limiting wheel is fixed, primary rotation adjustment of the nozzle body is completed, a rectangular block is made to deflect to drive a clamping mechanism to deflect, and therefore the rotation angle of the nozzle body is accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of air-jet spinning machines, in particular to a nozzle rotating device of an air-jet spinning machine. Background technique [0002] The textile industry is inseparable from today's life. Now some textile factories use air-jet spinning machines. The main principle of air-jet spinning is to use jet air to twist the fiber strips after drafting, and some ends of the fiber strips are free. The fibers are wrapped around the fiber sliver and spun. There are two kinds of single-nozzle and double-nozzle type. The latter has good and stable spinning quality. The fiber strips are drawn thin by the drafting device and output from the front roller. The grooved drum is wound into a bobbin. [0003] 1. The nozzles of traditional air-jet spinning machines mostly use rotating nozzles and tightening screws to adjust the rotation angle of the nozzles. When the nozzles are held in hand to tighten the screws, the nozzles are...

AI Technical Summary

Problems solved by technology

[0003] 1. The nozzles of traditional air-jet spinning machines mostly use rotating nozzles and tightening screws to adjust the rotation angle of the nozzles. When the nozzles are held in hand to tighten the screws, the nozzles are prone to deflection, and the angle of the nozzles cannot be adjusted slightly after tightening. Amplitude adjustment;

[0004] 2. The traditional way of fixing the nozzle is to fasten it with screws, which makes it inconvenient to maintain and replace the nozzle.
