Common Problem |
Causes |
Solutions |
|
1 |
Fabric can’t be cut;
Pile drawn or raised |
1. Machine speed is too fast; 2. No paper tape or film is filled up; 3. Pressure inefficient; 4. Pattern roller or bottom mould worn out; Lower voltage of power supply |
1. Reduce speed properly; 2. Fill up paper tape or film; 3. Increase pressure properly; 4. Replace with new pattern roller or grind the bottom mould. Equipped with 1KW single phase electronic AC stabilizer to booster the voltage. |
2 |
Some holes can’t be punched; Half side can’t be punched; Pile drawn or raised |
1. Pattern roller is installed leanly; 2. The surface of the bottom mould is not level; No paper tape or film is filled up |
1. Readjust pattern roller; 2. Readjust the surface of bottom mould;
Fill up paper tape or film |
3 |
Pattern roller( or horn ) doesn’t turn |
1. Speed governing circuit failed; 2. Copper sheet on control circuit board of motor short circuit; 3. Coil of motor burnt out; 4. Motor idles or driving part is stuck;
Synchronous belt broken |
1. Check or replace with speed circuit board or control box; 2. Check circuit and solve the problem; 3. Replace motor; 4. Check transmission parts from motor or pattern roller to horn and the motor’s gearbox;
Replace synchronous belt |
4 |
Pattern roller( or horn ) at full speed |
1.Speed governing circuit failed; 2. Coil of motor burnt out; 3. Speed governing circuit failed
4. Relay damaged |
1. Check or replace with speed circuit board or control box; 2. Replace motor’s speed governing circuit coil; 3.Check the circuit;
4. Replace relay |
5 |
Inefficient power from the horn |
1. The horn failed; 2. Piezoelectric wafter damaged; 3. Frequency of generator can’t be tracked; 4. Fuse of ultrasonic generator broken; Some transistors in large power set broken |
1. Replace the horn; 2. Replace the piezoelectric wafter; 3. Adjust current slightly or to minimum; 4. Replace fuse;
Replace broken transistors |
