Common problems and solutions of mask machine

Common problems and solutions of mask machine
Serial numberProblem DescriptionCause AnalysisSolutionRemarks
1Material roll offsetUnstable loading rackFirst of all, it must be fixed, and secondly, the roll holder should be level. Tighten the tightener, or increase the weight.
2CreasingUneven gantry frame with cloth material entrance1. 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.

3Face mask is crooked1. 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.

4Mask nasal bridge folds1. 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.

5Mask short side skew1. The shaping wheel is too tight;
2. The shaping wheel is uneven.
The shaping wheel should be adjusted parallel.
6Bad welding on the long side of the mask1. Welding tooth roller pressure is small;
2. The ultrasonic energy is not enough.
1. Adjust the roller pressure;
2. Check the ultrasound status.

7Bad welding on the short side of the mask1. 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.

8Mask slices cut continuously, or even wire1. 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.

9Nose bridge curlNose strips spread out during installation.The coil must be compressed first, and the installation is completed before cutting the strapping.
10Nostril mouth blocked1. 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.

11Nose bar is not straight1. 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.

12Adjustment of the last pressing wheel of the main body machinePressing 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.
