Analysis of the causes of thread pull-back in computerized quilting machines

Computerized quilting machines utilize an XY-Z motion system for quilting. The XY axes control the machine head's movement, while the Z axis controls the quilting process. Under the control of a precision computer system, computerized quilting machines can perfectly handle various complex patterns woven throughout the entire coordinate system. They are widely used for quilting patterns on various mattresses, sleeping bags, bedspreads, cushions, and summer quilts.

Generally, computerized quilting machines will experience some thread pull or backstitching issues during the quilting process. When such problems occur, the first thing to consider is the quality of the quilting machine itself, as well as the density, material, and twist rate of the quilting fabric. If backstitching is detected, the quilting needle should be checked immediately. If the needle is too thick or bent, it will offer no resistance to the fabric, leading to quilting failure. Replace the needle with a thinner one or a new one promptly.

If the problem is caused by the quilting machine's operation, it may be due to excessive machine speed, excessive thread tension, or an excessively large needle plate diameter. In this case, the problem can be solved by reducing the speed, reducing the thread tension, or using a smaller diameter needle plate hole.

Computerized quilting machines operate at high speeds and have a large workload, so proper maintenance is essential to maximize their production efficiency. During normal operation, regularly check all parts of the quilting machine for looseness. If any parts are loose, tighten them. If the quilting machine is used frequently, clean the lock cylinder sleeve regularly. If it has been used for eight hours or stored for an extended period, it needs to be cleaned and lubricated.
