Solution To Trouble Shooting Of Winding Machine

The trouble of needle jumping is mainly caused by the following reasons: Machine needle The seam and seam are not well matched. Solution: replace needles that are suitable for sewing and sewing materials. The quality of the stitch is not good and the twist is not uniform, which causes the stability of the coil is not enough. The solution is to solve the problem by choosing a reasonable suture. The twist should be right and the left side twists should be used. The needle is bent, blunt, worn or misplaced. Solution: replace the needle and install the needle according to the correct method. The spindle of a spinning spindle is convex due to some reason. Solution: properly repair the spindle and polish the spindle.

The movement of the needle varies from left to right. The downward movement is the take-up of the take-up rod and the feeding of the cloth teeth to enable the movements to be carried out smoothly enough time. The spinning shuttle is still rotating at the original speed for a week because of the adjustment. Zigzag machine The purpose of hook line time is to hook the surface line when the spindle tip is formed with a full and stable best line loop, thereby avoiding jumping needle phenomenon. As the slit material is generally used for fine threads, but no longer hooks, the solution is to adjust and make the needle to the coordinated position. Needle plate slot and presser foot groove are too wide and pressure on presser foot is not enough. Solution: replace needle plate slot, narrow groove presser foot, increase pressure.

The pressure foot plane of the zigzag machine is not closely related to the plane of the needle plate and the tooth surface of the tooth. Jump needle 。 Solution: grinding and pressing the feet and teeth, making the three parts of the plane close together, just one circle. The operator knows that when the thin material is slit, the spindle must be adjusted "fast"; when the thick material is slit, the spindle must be "slow". The reason is not difficult to understand. Due to the take-up effect of the take-up rod, the surface line ring which was originally enlarged and leaped by the spinning shuttle rapidly reduced until the bottom line drawn from the heart of the shuttle spindle was pulled into the sewing material to form a single interleaving. The spindle tips of the spinning shuttle reach the needle at the point of movement, pass through the face line loop, and continue to rotate in the movement. When it comes to its own radius, it jumps over the enlarged line like a rope skipping. Or replace qualified presser feet and teeth. The gap between the upper and lower sleeves of the needle bar is too large. Solution: replace worn sleeve or needle bar.
