Structure-optimized bobbin suction auxiliary system

Abstract

The invention discloses an auxiliary bobbin yarn adsorption system with an optimized structure. The auxiliary bobbin yarn adsorption system is characterized in that one end of a driven push rod is propped against a curved surface of a cam, and a bobbin yarn suction nozzle positioning sensor is fixedly arranged at the other end of the driven push rod; the driven push rod can slide in the length direction thereof to enable the bobbin yarn suction nozzle positioning sensor to get close to or far away from a bobbin yarn suction nozzle; a driving device drives the bobbin yarn suction nozzle to swing; an opening in the suction nozzle part of the bobbin yarn suction nozzle directly faces to the surface of a yarn bobbin; negative pressure is generated in the bobbin yarn suction nozzle; a sawtooth bent plate with a sawtooth structure on the surface extends a set distance from the opening in the suction nozzle part of the bobbin yarn suction nozzle into the bobbin yarn suction nozzle; an included angle of 10.5-11.5 degrees is formed between the sawtooth bent plate and the inner side wall of the bobbin yarn suction nozzle. According to the auxiliary bobbin yarn adsorption system, the angle of the sawtooth bent plate on the bobbin yarn suction nozzle and the curved surface of the bobbin yarn suction nozzle positioning cam are improved, so that a relatively ideal position between the bobbin yarn suction nozzle which goes upwards and the surface of the yarn bobbin can be reached, the air flow in the inner cavity of the bobbin yarn suction nozzle is high enough, the success rate of yarn suction of the bobbin yarn suction nozzle is increased, and the consumption of negative pressure for single connection is reduced.

Description

technical field [0001] The invention relates to a bobbin adsorption auxiliary system, in particular to a bobbin adsorption auxiliary system with an optimized structure. Background technique [0002] In the textile industry, the winding device is to process the bobbin with a small capacity into a knot-free bobbin with a large capacity and good shape, and remove impurities and yarn defects during the winding process. Since the bobbin has a very limited capacity, Tubes are changed more frequently, and at the same time, due to the quality of the yarn, the yarn clearer often removes impurities attached to the yarn, removes defects on the yarn and cuts the yarn, so the piecing cycle is an essential and important part of the automatic winding machine. As the name suggests, the splicing cycle means splicing bobbins and bobbin yarns, and the function of the bobbin adsorption system is to absorb the bobbin yarns and send them into the splicing cavity of the splicer. The bobbin yarn a...

If any one of the three systems is not in place, the joint will fail

[0003] At present, the bobbin suction nozzle often needs 3 times to suck the yarn, which makes the production efficiency of the machine low
