Mask machine maintenance methods and skills
The automatic mask body filming machine is mainly used for the automatic forming of the mask on the flat machine. After the whole roll of fabric is unrolled, it is driven by the roller, and the fabric is automatically folded, wrapped, and the nose bridge is pulled and unrolled, and then cut to length. In the edging fabric, the two sides are welded to the seal by ultrasonic, and after the ultrasonic side seal, it is cut into shape by a cutter, and the whole process is automatically controlled. The scientific and reasonable mechanical transmission configuration makes this machine extremely efficient. The special welding wheel and cutter wheel design has good wear resistance, which greatly improves the service life of the product.
Notes for tuning:
1. All adjustments must have a reference, otherwise it cannot be debugged later.
2. On the unwinding rack, pay attention to the up and down position of the nose bridge line, the convex direction is upward, and the nose bridge line passing bracket is equipped with a thread guide wheel. This part is currently missing from many drawings.
3. The tension is adjusted properly and the feeding position of the material belt is symmetrical. It is best to have a scale for easy adjustment.
4. Replace the folding mechanism with two or three tapered stepped shafts, and the upper and lower two installations should be careful not to install them in the opposite direction, and the adjustment height on both sides must be the same.
5. After the folding mechanism, the shaping roller is two up and down. At present, many drawings only have one. Need to redo two mounting plates and add a roller (component one) on top. There is a roller (component two) behind, and the distance between component one and two is best adjustable. Several rows of screw holes can be drilled on the platen to facilitate adjustment of the distance.
6. The long ribs of the upper nose bridge mechanism need to be chamfered. At present, many drawings do not have chamfers. This part needs to be redone and the metal parts can be modified.
7. There is only one side wall and one edge of the rolling knife on many drawings, and some edges of the rolling knife need to be redone.
8. There are many refueling skills, if you are proficient, you can change it in a minute or two. In fact, as a whole, all drawings are not problematic, and a mechanical engineer can handle it.
