Fault Phenomenon |
Cause judgment |
Solution |
| There is a power display, but the machine does not run | 1. The three-phase power supply is reversed | Swap any two of the three-phase lines |
| 2. The motor brake is not released | Press the brake clutch switch | |
| Can jog, but can’t drive fast | 1. The inching switch is not converted | Move the jog switch position |
| 2. Whether there is a power failure display (red light is on) | Check out the power outages everywhere | |
| Power failure indicator (red light) on | 1. Warp break | Check the power cut sheet, brown silk sheet, and see if there is any broken yarn |
| 2. The weft (bottom thread) is broken | Check the weft (bottom thread), connect the yarn | |
| 3. Pull belt roller roll | Reel with inspection roller, clear reel | |
| There are yarn breaks, but no downtime | 1. Whether the wire of the yarn breaking device is installed or not | Check wires everywhere |
| 2. There is a problem with the broken yarn circuit board | Check the circuit board for looseness, reverse insertion, and burn marks | |
| 3. The main circuit board is broken | Check whether the corresponding signal lights are normal according to the circuit diagram | |
| Motor brake failure | 1. There is a problem with the brake circuit | Check the power supply of the brake coil, and the control circuit |
| 2. Brake coil burnt | Replace the brake coil | |
| 3. The brake pads fall off or are worn | Re-glue the brake pads or replace the brake pads | |
| The front steel box collided with the brown silk sheet of the first brown frame | 1. The position of the front steel box is too far back | Adjust the position of the steel seat forward, but do not touch the belt plate |
| 2. The height of the front steel box is too high | The height of the steel box generally used is 60MM. If you must use a higher height, you can start from the second or third piece without the first brown frame. | |
| If the warp does not advance, the tape cannot be woven | 1. The belt is too thick or the weft density is too tight | Generally, the belt that can be woven is about 3MM thick. |
| 2. The pull of the front pulley is not enough | To replace the thicker pattern, generally PP belts should use thick embossed rollers | |
| 3. The single bearing of the front pulley with the roller is broken | Replace single bearing or replace keyway pulley rollers |
Different types of looms with different needles have different problems and different solutions. This is just to sort out the problems of ordinary fabric needle looms. The specific solution is best to consult the technical personnel of the corresponding belt loom manufacturer.
