Broken yarn processing device of ring spinner

Abstract

The invention discloses a broken yarn processing device of a ring spinner, belonging to the technical field of textile. When the broken yarn processing device is used for ring spinning, certain pressure is produced to a yarn guide hook by a yarn, when the yarn is broken, the phenomenon that the pressure is eliminated is utilized to judge whether the yarn is broken or not in the ring spinning process, and the pressure change is utilized to process the broken yarn by setting an air valve switch, an air distributing valve and an actuator cylinder and controlling the two working states, namely opening and closing of the air valve switch, thus the broken yarn processing device has the characteristics of compact structure and is convenient and accurate in operation.

Description

technical field

[0001] The invention relates to a broken yarn processing device of a ring spinning machine, more specifically, a broken yarn processing device of a ring spinning machine using the principle of an air valve switch, which is used for ring spinning production and belongs to Textile machinery technology field. technical background

[0002] Before the present invention, in the prior art, such as the pneumatic broken yarn detection device described in the Chinese patent application No. 201020618311.1, a rotatable broken yarn detection rod is used, one end of which is lapped on the yarn, and the other end is An air valve switch is installed on the movement track, and the closing and conducting states of the air valve switch are controlled by using the difference in the position and state of the yarn break detection rod in the two situations of yarn conduction and yarn breakage. Since the yarn path of ring spinning is relatively compact, if the yarn break detection ...
