Common problems and solutions of mask machine
| Common problems and solutions of mask machine | ||||
| Serial number | Problem Description | Cause Analysis | Solution | Remarks |
| 1 | Material roll offset | Unstable loading rack | First of all, it must be fixed, and secondly, the roll holder should be level. Tighten the tightener, or increase the weight. | |
| 2 | Creasing | Uneven gantry frame with cloth material entrance | 1. Adjust the gantry roll feeder to ensure that the fabric direction is the same as the pleating plate; 2. The part of the pre-fold and the fold should be consistent. | |
| 3 | Face mask is crooked | 1. The entrance end of the roll is crooked; 2. The material roll is biased to one side; 3. The position of the flanging width positioning board is deviated, or the bell mouth. | 1. Adjust the material roll holder so that the fabric and the folding board are in the same direction; 2. Adjust the roll holder, adjust the folding position of the roll; 3. Adjust the position of the width positioning plate and correct the shape of the bell mouth. | |
| 4 | Mask nasal bridge folds | 1. The bridge of the nose is not cut off; 2. The cloth roll is biased; 3. The position of the small baffle is incorrect before welding; 4.L pressure plate is too loose or too tight or too inclined. | 1. Adjust the nose bridge cutter; 2. Adjust the cloth roll; 3. Adjust the curling small baffle; 4. Adjust the L pressure plate. | |
| 5 | Mask short side skew | 1. The shaping wheel is too tight; 2. The shaping wheel is uneven. | The shaping wheel should be adjusted parallel. | |
| 6 | Bad welding on the long side of the mask | 1. Welding tooth roller pressure is small; 2. The ultrasonic energy is not enough. | 1. Adjust the roller pressure; 2. Check the ultrasound status. | |
| 7 | Bad welding on the short side of the mask | 1. Welding belt gear has low pressure; 2. The ultrasonic energy is not enough; 3. The ultrasonic steel mold is not level with the gear; 4. The welding position is misaligned with the nose bridge. | 1. Adjust the roller pressure; 2. Check the ultrasonic state; 3. Adjust the height of the ultrasonic die head so that the die head and the roller are relatively parallel; 4. Loosen a few meters of screws between the wheel shaft and the gear, and turn the wheel to adjust the welding position. | |
| 8 | Mask slices cut continuously, or even wire | 1. The slice is too high and oblique; 2. The slice position is off. | 1. Adjust the cutter height and adjust the cutter wheel pressure; 2. Loosen a few meters of screws on the wheel shaft and gear, and turn the wheel to adjust the cutter position. | |
| 9 | Nose bridge curl | Nose strips spread out during installation. | The coil must be compressed first, and the installation is completed before cutting the strapping. | |
| 10 | Nostril mouth blocked | 1. The bridge of the nose is too hard or too soft; 2. The thread inside the nose bridge is stuck, or the outlet is slipping; 3. The exit position is inside or outside; 4. The cloth roll is misaligned. | 1. Replace the nose bridge material; 2. Clean the jamming line, adjust the two feeding rollers in front of the nose bridge cutter to compress or lift up; 3. Adjust the angle of the nose bridge mouth; 4. Adjust the cloth roll. | |
| 11 | Nose bar is not straight | 1. The entrance end of the nose bridge line is not straightened; 2. The line of the bridge of the nose is hard, and it has been bent in the roll; 3. The quality of the iron core in the bridge line is poor, hard or thick, and it is easy to bend and deform after rolling. | 1. Adjust the position of the self-locking wheel of the nose bridge roll material on the material rack to go down, or increase the weight of the self-locking wheel to straighten the nose bridge line; 2. Replace the bridge material. | |
| 12 | Adjustment of the last pressing wheel of the main body machine | Pressing too loosely or too tightly will cause the material to float, or the mask will deform. | After adjusting, the pressure wheel can be pressed to the level to fly out. | |
