Reasons for skipping stitches in automatic sewing machines
We often have many unexpected small problems in the process of using the sewing machine. Many people do not know how to solve these problems. Today we will talk about the reasons why the automatic sewing machine skips stitches, and find the key to the problem.
1. The needle eye of the automatic sewing machine is too small to form a thread loop, and the needle of the automatic sewing machine is bent, causing the wrong position of the upper thread and the lower tie. Solution: In this case, just change a needle.
2. The height position of the needle bar of the automatic sewing machine causes the timing of the sewing thread of the needle and the hook to be wrong, and the upper and lower threads do not meet at the correct time, resulting in the upper and lower threads not being hooked.
Solution: adjust the position of the height of the needle bar.
3. The material to be sewn is too thick, and the size of the needle is too small, which changes the formation time of the thread loop. Solution: In this case, you can change the needle to a larger size. The material to be sewn should not be larger than the tolerance range of the machine. If the material is too thick, you should choose a thick material sewing machine.
4. The lock tip of the rotary hook is bald and shortened, and the needle skips when sewing at a corner. Solution: You can change a hook.
5. The thread loosening cam will also cause skipped stitches.
Solution: adjust its tightness.
《Needle zero position》 Set the machine origin, after the zero reset is completed, start the pull rod to make the machine head pass the needle zero position probe and then stop, move the machine head to the left side of the needle bed by hand, and align the left outer side of the machine head with the first position of the needle bed. At the needle, press the F1 key to write the currently displayed needle value. (First, enter the number of needles in one inch of the flat knitting machine and the total number of needles in the flat knitting machine, and then set the synchronous belt pitch correction parameters)
1. Automatic head turning: After completing a quilting operation, the seam head can be turned up automatically, which is convenient for the replacement of quilted products.
2. Wire break detection: When the wire is broken, it will automatically stop, the red light of the wire break detection device will be on, and it can go back to the broken wire for quilting.
3. Step quilting: Various step quilting operations can be performed
4. Emergency stop protection: press the red emergency stop button at any time during work, the quilting machine will immediately power off and stop
5. Process setting: It has the settings of various practical process parameters such as stitch selection, angle correction, pattern scaling, etc. High-speed and accurate quilting at 2000 rpm, low noise, long machine life, and quilting that meets customer needs. The target quilting area of high-quality and high-yield quilted products is equal to the size of the machine, and the smallest machine installation area is achieved. ) drives the machine head to run in the X direction, and the servo motor (optional) drives the machine head to run in the Y direction, and the embroidery frame is fixed, which ensures the minimum machine transmission distance and stable long-term work. Fast and accurate, and avoids damage and replacement of the handpiece in the future.
