Weaving yarn end fast connecting gasbag

Abstract

The invention provides a spinning thrum portable aerocyst, including a tube body, a locking cover and a gas cover, the inner cavity of said tube has a rubber shrinkage sleeve, two ends of rubber shrinkage sleeve is fixed between tension sleeve of two ends of tube and lock sleeve, the cylindrical surface of two ends of mouth of tube has multiple bosses, the locking cover is sockets at the two ends of tube, the circumference of locking cover has multiple locking grooves, the boss of tube and the locked face of locking groove are in the clamping state; the inlet tube sets at the tube, the mouth of inlet tube has a non-return gaslock, the mouth of inlet tube is connected with gas cover connecting the controlling gas source. The aerocyst by retractable rubber shrinkage sleeve controls in make and break of high-pressure air flow, the movement is stable, the sealing effect is good, so that it not have to manually close pneumatic valve, adapting the high speed rotation of air-jet spinning machine to realize automation air-jet spinning.

Description

technical field [0001] The invention relates to a textile yarn end quick-connecting airbag, in particular to an airbag for controlling the interruption of high-speed rotating air flow when the yarn ends are spliced. Background technique [0002] Air-jet spinning is a unique new spinning method, which has the advantages of high speed, high output, and less hairiness in yarn. The yarn forming mechanism of air-jet yarn is to use the high-speed rotating air field of two-stage nozzles to blow and twist the outer edge fibers of the fiber aggregate, so that it can coat the inner layer fibers to form air-jet spun yarns. In the prior art, in air-jet spinning, in order to ensure the quality of the yarn, the yarn clearer is used to detect the yarn. When the yarn clearer detects a defect in the yarn, the yarn clearer will automatically cut off the yarn, and the high-speed rotating air flow needs to be turned off. , so that the broken cotton yarn temporarily stops running, the broken ya...

Problems solved by technology

In the prior art, in air-jet spinning, in order to ensure the quality of the yarn, the yarn clearer is used to detect the yarn. When the yarn clearer detects a defect in the yarn, the yarn clearer will automatically cut off the yarn, and the high-speed rotating air flow needs to be turned off. , so that the broken cotton yarn temporarily stops running, the broken yarn end is connected by the manipulator, and then the high-speed rotating air flow is connected, but the high-speed rotating air flow needs to be manually closed. The air valve is inconvenient to operate and is not suitable for air-jet spinning machines High-speed operation, it is not easy to realize the automation of air-jet spinning
