The troubleshooting method of the disconnection fault of the computer bag opener

usually,Computer bag opening machineIf it is used for a long time, various failures will often occur. One of the more common ones is disconnection faults in mechanical faults. This fault phenomenon of the computerized bag opener is usually that the thread breaks in the first few stitches after the start of sewing. Sometimes the left needle thread is broken, sometimes the right needle thread is broken, and sometimes two needle threads are broken at the same time. The ball of thread is under the fabric.

When this kind of malfunction occurs in the computer bag opener, we first need to check and adjust the hook thread hooking time and the height of the hook, polish the hook and the burrs that may cause the thread to hang, and clean the upper thread clamping plate. Cloth scraps and thread ends restore the function of the thread clamping plate. If this still does not solve the broken thread of the computer bag opener, then we need to pay attention to all the movements of the machine while the fabric is repeatedly sewn. We usually find that after the high-speed feeding, when the needle starts to sew , The upper thread tension plate is closed and it starts to work. When two stitches are sewn, the thread tension plate opens again and then closes again. When the upper thread clamping plate is opened, the upper thread loses pressure, causing the upper thread to be pulled under the needle plate of the computer bag opener without pressure, causing a bird's nest line on the bottom of the fabric Group or disconnection.At this time, we need to consider whether the filter is clogged.

Because automaticallyComputer bag opening machineThe actuators are all pneumatic, their electromagnetic pneumatic switches are all connected in series, and air filters are installed at both ends of the switches to filter air and silence. However due toBag opening machineThe use time is long, the filter is easy to be blocked by dust, so that the air received a certain resistance when passing through the filter. And all the electromagnetic pneumatic switches of the computer bag opener are stringed together, so when sewing one or two stitches,Because the electromagnetic air switch needs to controlThe movement of the two cylinders of the upper thread scissors and the bottom thread scissors,needLoosen the clamped thread. However, the resistance of the thread release cylinder is very small, and the return air of the bottom thread pay-off cylinder is too late to be discharged from the blocked air filter, and flows to the thread release solenoid switch, causing the thread release cylinder to act. So, we only need toComputer bag opening machineFold down all the air filters, use a decontamination spray gun or other methods to clean the air filter, put it back and test the machine, you can eliminate the disconnection fault.
