Common faults and Solutions
| Item | Parts Assy | Problem and fault | Solutions |
| 1 | Fabric unwinding device | The discharge shaft makes a buzzing sound and keeps turning |
Check whether the displacement sensor steel sheet behind the swing bar is loose, lift the front swing bar, adjust the steel sheet to the sensor sensing position and lock the screw; check whether the cloth is loose and whether the motor is idling, move the cloth position to the position in the butt welding wheel, and lock |
| 2 | Fabric unwinding device | Too much or too little cloth tension | The tension of the cloth is equal to the weight of the swing bar. Move the tension spring on the counterweight bar to a distance, so that the tension of the tension spring becomes larger and the gravity of the swing bar becomes smaller, so the tension is smaller. The relative position tension can be adjusted by adjusting the angle of the sensing metal sheet of the displacement sensor. |
| 3 | Fabric unwinding device |
Adjustment of cloth position | First adjust the position of the positioning horn with the welding wheel as the center, and then adjust the cloth on the discharge shaft with the positioning horn as the center. The cloth should be smooth through the positioning horn. |
| 4 | Nose Wire Installation device | Length adjustment of nose line | Loosen the screw on the fixed block of the feeding cylinder to move for a certain distance, then loosen the fastening nut at the end of the feeding cylinder, turn the adjusting nut to adjust. The adjusted distance should be the same as the moving distance of the fixed clamp of the feeding cylinder. The adjusted distance is the extended distance of the nose line; After the distance adjustment, the fixed screw under the nose line cutter should be loosened to move the nose line cutter so that the center of the cut nose line is in the center of the rotating finger clamp; if the center of the nose line is not in the middle of the rotating finger clamp, the fused nose line will shift on both sides in turn. |
| 5 | Nose Wire Installation device | Can't cut off the nose line | The main problem with rhinotomy is 1. Is the air pressure sufficient, 2. Whether the cutting edge is damaged 3. Whether the installation position of cutter is correct. |
| 6 | Nose Wire Installation device | Specification of replacement nose line | To change the specification of the nose line, it is necessary to change the fixing clip, feeding clip and finger clip, so that the width of the clip is the same as that of the nose line. |

| 8 | Fusing device | Position adjustment of welding wheel relative to nose line | First adjust the position of the adjusting wheel to the center, and then check whether the position of the cloth fusion and the nose line is correct. If the position difference is too much, it is necessary to lift the welding wheel to make the gear on the welding wheel separate from the height of the main driving wheel gear below. Turn the welding wheel to check the welding position; if the position is still a little poor, turn the handwheel of the regulating wheel to adjust to the exact position. |
| 9 | Fusing device | Insufficient fusing fastness | Adjust the two limit screws to the same height so that the welding wheel is completely pressed on the ultrasonic mold. During the ultrasonic pressing process, it cannot be pressed to the bottom at one time. Try to press slowly to avoid damage to the ultrasonic mold and the fusing wheel; Check whether the ultrasonic wave is normal. |
| 10 | Fusing device | Position adjustment of cutter wheel relative to welding wheel | 1. The cutting position and welding position are not right before and after. If there is too much difference between the positions, it is necessary to lift the cutter wheel to make the gear on the cutter wheel separate from the height of the main driving gear below. Turn the cutter wheel to check the cutting position; if the position is a little bit worse, turn the handwheel of the adjusting wheel to adjust to the exact position; if the cutting position is not right, loosen the fixed screw under the cutter wheel group, and move the position of the whole cutter wheel group. 2. When the cutter wheel is depressed, observe the pressure sensor gauge connected with the cutter wheel. The number of each row of the pressure gauge represents the pressure of the left and right ends of the cutter wheel. After being depressed, the pressure at both ends should be adjusted to a similar value. |
| 11 | Fusing device | Cutter cannot be cut off | Check whether the cloth moves to the cutter limit position; Check whether the pressure of the cutter is enough. |
| 12 | Ear loop feeding | Length adjustment of ear loop | 1. Loosen the screw of the rotating disk, move the protective disk at both ends of the rotating disk, and loosen the screw of the return clamp on the protective disk to move the same distance. 2.
