Common faults of computerized sewing machine

Computerized sewing machineThe emergence of the company has brought high economic benefits to enterprises in the clothing, shoe-making, and home textile industries, and has improved the work efficiency of relevant work operators. However, in the actual use of the computerized sewing machine, various malfunctions and problems will inevitably occur. Among them, the faults such as booting, withdrawal, thread trimming, thread sweeping, and continuous thread cutting have been plagued by operators. So, how should we solve these computer sewing machine accessories?

There are no motion problems for actuators such as needle withdrawal, thread trimming, and thread sweeping. When the computerized sewing machine withdraws the needle, we need to confirm whether the reverse seam switch is turned on, whether the electromagnet is burned out, whether the corresponding connector is plugged in, whether the electric contact wire is worn off by the pulley, and whether the needle back circuit of the control board is faulty. When the reverse stitching switch of the computerized sewing machine is damaged, or the actuators such as thread trimming and thread sweeping do not act, we must check whether the corresponding plugs of the corresponding accessories are properly inserted. Because the plugs of the reverse seam switch, thread trimming, thread sweeping and other actuators of most brands of computer sewing machines are designed on one plug, which may be pulled down by mistake.

Regarding the problem that the computer sewing machine is not powered on, we can first check whether the power switch is in good contact and whether the fuse on the power board is blown when the power plug is plugged in. If the above two items are good, then check whether the cement resistor on the power board is damaged. If it is damaged, replace the resistor with the same resistance. In addition, there is a problem of continuous thread cutting for computer sewing machine parts. As long as we hear the cutting line, the knife we ​​think of is blunt. If the cutter is changed or the thread is cut continuously, we have to consider whether the position of the thread trimming cam moves.
