Yarn feeding mechanism of warp knitting machine

Abstract

The invention provides a yarn feeding mechanism of a warp knitting machine, mainly comprising a yarn feeding transmission shaft rotatably arranged on a stand of the warp knitting machine and a plurality of yarn cylinders fixedly arranged on the yarn feeding transmission shaft, wherein the stand is also provided with a motor and a worm and gear reducer which is connected with the motor, the end of the yarn feeding transmission shaft is coaxially connected with a large gear, an output shaft of the reducer is coaxially connected with a small gear, and the large gear is in transmission connection with the small gear through a synchronous belt. The warp knitting machine is easy to operate, has strong intuition by detecting the yarn feeding condition through data, is convenient to be digitally controlled, accurately controls the yarn feeding amount and can avoid different intervals between every two unit patterns due to different yarn feeding speeds.

Description

Technical field [0001] The invention relates to a warp knitting machine. Background technique [0002] In the existing technology, the yarn feeding mechanism of traditional warp knitting machines all adopt mechanical gear transmission devices. The angular speed of the transmission shaft used to drive the rotation of the yarn drum is constant. However, since the yarn on the yarn drum is Reduce layer by layer. As the yarn decreases layer by layer, the amount of yarn fed by the drive shaft becomes shorter each time it rotates. Therefore, the length of yarn pulled by the warp knitting machine will decrease layer by layer. However, the warp knitting mechanism and transmission The working cycle and action of the mechanism remain unchanged, so when the amount of yarn fed is inconsistent, the tension of the yarn is different, and the intervals of the repeated unit patterns woven from the fabric will change, affecting the overall aesthetics of the pattern.

Problems solved by technology

[0002] In the prior art, the yarn feeding mechanism of the traditional warp knitting machine all adopts a mechanical gear transmission device, and the angular velocity of the transmission shaft used to drive the rotation of the yarn drum is constant. However, since the yarn on the yarn drum is Decrease layer by layer, as the yarn decreases layer by layer, the amount of yarn feeding becomes shorter every time the drive shaft rotates, so the length of the yarn drawn by the warp knitting machine will decrease layer by layer, but the warp knitting mechanism and transmission The working cycle and action of the mechanism are always the same, so when the amount of yarn feeding is inconsistent, the tension of the yarn is different, and the interval of the repeated unit pattern woven by the fabric will change, which will affect the overall aesthetics of the pattern
