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.|
