Problems of mask machine

Masks are indispensable protective equipment in the epidemic, so far people still need to wear them, and many families are still storing masks. At present, the upsurge of buying masks has basically passed in China, but the production of masks has not stopped. Even many enterprises in China begin to focus on foreign countries and export masks to foreign countries. The expansion of mask production will inevitably lead to the demand for mask machines. With the huge demand, many mask manufacturers have also expanded their production. In the emergency production environment, some factories do not stop work 24 hours a day, the mask machine continues to work, almost all the time, under this overload operation, the mask machine is prone to problems.
Editor sorted out the causes and solutions of the problems of the mask machine, and the needed relatives can collect them!
1. For the instability of the left and right offset of the material coil, the feed frame shall be fixed first, followed by the horizontal feed frame, and the wheel shall be tightened or the load shall be increased.
2. The door frame at the entrance of the tapered cloth belt is uneven. Adjust the door frame coil frame to ensure that the direction of the cloth is consistent with that of the folding board
3. The pre compression fold and compression fold should be relatively horizontal, and the mechanism spacing should be the same.
4. The long side of the mask is cut and curled. The inlet end of the drum is bent
5. Flanging width positioning plate or corner position deviation 1. Adjust the coil holder so that the cloth is in the same direction as the folding plate or adjust the coil holder and the folding position of the coil
6. Adjust the position of the width positioning plate, correct the shape of the bell mouth, the nose part of the mask is 4 times, the nose is not cut off.
7. Cloth roll deviation. The small baffle plate is not in the right position before welding;
8. The pressure plate is too loose or too tight or too inclined. Adjust the nose beam cutter; adjust the cloth roll; adjust the flange small baffle; adjust the L-shaped pressure plate
9. The short side of the mask is inclined and the forming wheel is too tight
10. The forming wheels are not uniform and should be adjusted in parallel.
11. The long side of the mask is seriously welded. Low welding roller pressure
12. The ultrasonic energy is not enough. Adjust the roller pressure; check the ultrasonic state
13. The short side of the mask is seriously welded. Low welding pressure of belt gear
14. Ultrasonic energy is not enough. Uneven ultrasonic steel mould and rolling gear
15. The welding position is misaligned with the bridge belt. Adjust the roller pressure
16. Adjust the height of the ultrasonic die head so that the die head is relatively parallel to the drum
17. Loosen the screw of roller shaft and gear for several meters, and turn the roller to adjust the welding tooth position
18. The mask piece is continuously cut, even the wire piece 1. The knife is too high and tilted; the position of the knife is 1.1, adjust the height of the knife and the pressure of the cutting wheel; turn away the roller shaft and the gear for several meters, and turn the roller to adjust the position of the knife
