Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, and more specifically, to a yarn pressing plate moving device of a warp knitting machine. Background Art

[0002] A knitted fabric is formed by simultaneously looping one or several groups of yarns arranged in parallel on all the working needles of the warp feeding machine. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine.

[0003] In the prior art, the warp knitting machine is not convenient for fixing the gauze, and has no certain guiding and supporting effect on the gauze, which easily makes the gauze uneven, thereby affecting the overall effect of the product, and is not convenient for adjusting its position, so it is not practical.

[0004] After searching, the Chinese patent with authorization announcement number CN213978075U discloses a yarn pressing device for a warp knitting machine, which rolls the gauze around the outer wall of the cylinder, starts the motor, and the output shaft of the motor rotates to drive the disc to rotate and then drives the second rotating shaft to rotate. The rotation of the second rotating shaft drives the push rod to move and then drives the connecting block to move. The movement of the connecting block drives the guide rod to slide and then drives the support rod to move. The movement of the support rod drives the cross rod to move and then drives the mounting plate to move. When adjusted to the appropriate position, the gauze is pulled so that the gauze passes between the two sets of rollers. The rotation of the rollers plays a certain guiding role on the gauze. The rollers make the gauze flatter and less prone to wrinkling, thereby improving the quality of the product and facilitating adjustment. The vertical rod is reset to drive the movable rod to reset and then drive the fixed block to reset, so that the fixed block abuts against the gauze, so that the fixed block fixes the gauze, which is convenient for operation and improves work efficiency.

[0005] However, when this structure is actually used, the gauze passes between the two sets of rollers, and the rotation of the two rollers plays a certain guiding role on the gauze. However, during the rotating conveying process, the tightness of the gauze on the rollers cannot be adjusted, which causes the gauze to be easily displaced during the conveying process, thereby affecting the use effect.
