Automatic doffing silk suction device and waste silk treatment method thereof

Abstract

The invention relates to an automatic doffing and silk suction device and a method for treating waste silk thereof, comprising a silk outlet joint extending into the silk suction pipe, an airflow core respectively connected with the silk suction port and the silk exit joint, and an airflow core arranged at the silk suction port The wire catching sealing plate at the end, the piston, the wire outlet joint and the air flow core are installed together on the suction wire seat. Connected compressed air inlet, the other side of the airflow core is connected to the piston, the top of the piston is located under the wire catcher sealing plate, the lower part of the airflow core extends from the radial direction downwards with evenly distributed oblique long holes, and the lower part of the oblique long holes is connected with the outlet The threaded joints communicate with each other, and the upper end communicates with the compressed air channel. In the present invention, by inputting compressed air into the airflow core of the yarn suction device, the high-speed rotating airflow formed by the oblique long hole and the atmospheric pressure at the yarn suction mouth generate a pressure difference, thereby forming a negative pressure in the yarn suction mouth, and then sucking the waste silk into the suction The negative pressure used does not require the use of a fan, which avoids the problems of high fan power, frequent startup, and high energy consumption, and greatly reduces energy consumption.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a twisting and texturing machine. Background technique [0002] During the spinning process of the false twist texturing machine, the chemical fiber filament needs to be wound onto the bobbin through the winding mechanism to complete the winding of the thread. After a spinning bobbin is fully wound, it is necessary to replace the bobbin. At this moment, the long filaments must be cut, and after the new bobbin is installed, the tow is wound on the new bobbin. Since there are more than 200 winding bobbins on a texturing machine, that is, there are many silk threads, when changing the bobbin at one spindle position, other spindle positions will continue to work, so it cannot be shut down. When replacing the bobbin, the cut silk thread is still continuously conveyed from the roller. At this time, it is necessary to use a suction device to suck the sent filament into the silk storage...

Problems solved by technology

[0003] A commonly used method at present is that during the automatic can change of the winding device, the waste silk produced by the suction device is transported to the waste silk box at the end of the machine through the waste silk pipeline along the length of the machine, and the waste silk pipeline passes through a The fan generates negative pressure to convey the waste silk, the fan power is large, it starts frequently, and the energy consumption is high

[0004] The other is that the waste yarn produced by the yarn suction device is collected according to the automatic doffing working area. There is no fan and the energy consumption is small. The probability of being on the roller is high, which cannot adapt to the current higher and higher machine speed, and the waste silk is generated at a faster speed, resulting in the waste silk sent to the suction channel will be piled up on the machine and entangled, causing great harm
