Broken yarn pneumatic processing device of ring spinner

Abstract

The invention discloses a broken yarn pneumatic processing device of a ring spinner, which comprises a yarn guide hook, an actuator cylinder, an air dividing valve and an air valve switch, wherein the air valve switch comprises a yarn guide hook turning plate, a shell internally provided with a cavity, a pressure spring, a pressure regulator block, a limit block and a valve rod; the lower end of the valve rod, an outer bushing, an inner lining tube and a sealing gasket form a sealing cavity when the valve rod is vertical to the straight handle end of the yarn guide hook; and the valve rod canbe pushed for opening or closing the sealing cavity through the movement of the limit block. In the scheme, the broken yarn processing device is designed by using the principle that the pressure state of the yarn guide hook is different between two states of guiding yarns and breaking the yarns, and the elasticity of the spring and the magnetic force of a magnetic device are used as a dual-pushing force, thus the action adaptability of the air valve switch under different conditions of high count yarns, medium count yarns and low count yarns is enlarged, and the purpose of expanding the application range of the broken yarn processing device is achieved.

Description

technical field [0001] The invention relates to a ring spinning machine, in particular to a broken yarn pneumatic processing device of the ring spinning machine. Background technique [0002] Yarn breakage is a common problem in spinning. In the prior art, when the ring spinning machine breaks the yarn, the method and device that the suction pipe continuously absorbs the drawn broken yarn strands are used to deal with the broken yarn accident. The processing method and device have the following problems: 1. Since the broken yarn strands are still continuously provided, they are absorbed by the suction pipe, thus causing a large amount of waste of strands; Expensive. [0003] In response to the above problems, the applicant once disclosed a yarn breakage processing device for ring spinning machines (Chinese patent 201020618311.1), which uses a rotatable yarn breakage detection rod, one end of which is overlapped on the yarn, and the movement track of the other end An air v...

Problems solved by technology

This treatment method and device have the following problems: 1. Since the broken yarn strands are still continuously provided, they are absorbed by the suction pipe, thus causing a large amount of waste of strands; Expensive

But in production practice, it is found that there are still the following defects: 1. The detection method is defective and inconvenient to operate. When doffing each time, the detection rod may slip off from the yarn, resulting in the failure of judging whether the yarn is open or broken. According to the loss, it is necessary to put the detection rod back on the yarn, and the operation is even more inconvenient; 2. The power to open the air valve switch is insufficient, and the yarn breakage detection rod falls under gravity when the yarn is broken and provides the driving force for the air valve switch Smaller, the range of application of the yarn is limited
