Forming knitting machine for manufacturing seamless down jacket fabric

Abstract

The invention discloses a forming knitting machine for manufacturing seamless down jacket fabric, which comprises a circular knitting machine and a creel, a yarn supply mechanism is arranged in the creel, the side surface of the creel is provided with a butt joint mechanism and a clamping mechanism through a side plate, the surface of the side plate is also provided with an air cylinder and an ultrasonic bonding device, the device has the beneficial effects that the tail end of the yarn is in butt joint with the thread end of the new yarn bobbin through the butt joint mechanism, butt joint can be completed in the process that operation of the circular knitting machine is not affected, and before butt joint, when the first photoelectric switch detects that the tail end of the yarn passes through, the first photoelectric switch is turned on, and the yarn bobbin is driven by the second photoelectric switch to rotate. A driving source of the clamping block is controlled, the clamping block is closed, the tail end of the yarn is clamped, the situation that the front yarn loses tension to be bent, and butt joint is affected is prevented, the aligning block is used for aligning the tail end of the yarn and a new thread end in parallel, tension is kept, and local thickness and burrs can be reduced through parallel bonding.

Description

technical field [0001] The invention relates to a forming knitting machine for making seamless down jacket fabrics, belonging to the technical field of knitting machines. Background technique [0002] The production of seamless down jacket fabrics generally adopts circular knitting machine, circular knitting machine, scientific name knitting circular weft knitting machine (or called circular knitting machine), and the loop forming system of circular knitting machine (called the number of yarn feeds or loops in the enterprise). The number of channels, referred to as the number of channels) is large, the rotation speed is high, the output is high, the pattern changes quickly, the fabric quality is good, the process is few, and the product adaptability is strong. The circular knitting machine is composed of frame, yarn supply mechanism, transmission mechanism, lubrication and dust removal Cleaning) mechanism, electrical control mechanism, pulling and winding mechanism and other...

AI Technical Summary

Problems solved by technology

[0003] Among them, the existing yarn supply mechanism is to supply the thread through the yarn bobbin and the yarn storage device. When the yarn bobbin is finished, it needs to be manually replaced with a new yarn bobbin and the yarn is docked. The operation is complicated, and the docking effect is not good, and it is difficult to meet Demand for efficient production of large circular knitting machines
