Splicing device with single-spindle yarn suction nozzle structure and splicing method of splicing device

Abstract

The invention discloses a splicing device with a single-spindle yarn suction nozzle structure and a splicing method of the splicing device, and belongs to the technical field of textile splicing equipment. According to the splicing device with the single-spindle yarn suction nozzle structure and the splicing method of the splicing device, the splicing device comprises a single-spindle yarn suctionnozzle, wherein the single-spindle yarn suction nozzle is fixedly mounted on a wallboard of each spindle through a mounting base on the single-spindle yarn suction nozzle; the single-spindle yarn suction nozzle communicates with the upper air door negative-pressure air pipe through a connecting pipe, so that the distance between the single-spindle yarn suction nozzle and the upper air door negative-pressure air pipe is relatively short, and the phenomena of yarn winding and yarn blocking are not prone to occurring; and the single-spindle yarn suction nozzle comprises a suction nozzle elbow, the lower part of the suction nozzle elbow is connected with a yarn suction nozzle body, the yarn suction nozzle body is fixed to the suction nozzle elbow in a hooping mode and is matched with a sensorfor positioning, and therefore, a swing air cylinder is accurate in positioning and easy to adjust and the yarn suction nozzle body can rotate around the suction nozzle elbow and swing up and down.

Description

technical field [0001] The invention relates to the technical field of textile splicing equipment, in particular to a splicing device with a single-spindle yarn suction nozzle structure and a splicing method thereof. Background technique [0002] The structure of the vortex spinning device is simple, and the high-speed rotating parts are canceled, and the moving yarn is twisted by means of the high-speed rotating airflow. During vortex spinning, the fibers are twisted by means of an air flow. At present, each splicing trolley is equipped with a small suction nozzle. In order to provide negative pressure, the splicing trolley needs to open the air duct while moving, which makes the yarn suction channel long and complex in structure, which is prone to yarn blocking and winding problems. ; At the same time, it also adds a certain resistance to the walking of the trolley, which causes the trolley to run unsmoothly.

AI Technical Summary

Problems solved by technology

At present, each splicing trolley is equipped with a small suction nozzle. In order to provide negative pressure, the splicing trolley needs to open the air duct while moving, which makes the yarn suction channel long and complex in structure, which is prone to yarn blocking and winding problems. ; At the same time, it also adds a certain resistance to the walking of the trolley, causing the trolley to run unsmoothly

[0003] Existing splicing trolleys have complex structures and relatively large car bodies, such as figure 1 As shown, after receiving the splicing signal, the splicing trolley 1 moves along the track to the spindle position that needs splicing. The pipe 12 will be connected with the suction port 32 to provide negative pressure for the small suction nozzle 11, and the arrow indicates the direction of air flow

Splicing trolley 1 needs to open the damper every time it passes a spindle position, which increases the resistance of the trolley running and also has the risk of being stuck; in addition, it needs to provide a separate air duct and fan to form a negative pressure , so that the distance between the small suction nozzle 11 and the negative pressure tube 12 is longer, and the phenomenon of yarn winding and yarn blocking is easy to occur
