FAQ
Die-cutting Position Movement
1.Adjust the gap between the die-cutting and pulling rolls. 2.Adjust the gap between anvil cylinder and die cylinder. 3.Add sponge blocks of appropriate hardness to the wooden die 4.Replace the anvil cover.
Inaccurate Paper Feeding
1.Turn on the fan and check whether the fuse controlling the fan motor is blown. 2.Check the vacuum pressure and adjust the fan pressure. 3.Check whether the rotation direction of the fan motor is reversed. 4.Adjust the vacuum chamber switch. 5.Check whether the air duct is damaged, replace the air duct if damaged. 6.Check whether the air outlet is blocked. 7.Adjust the dust removal mechanism as required. 8.Reduce the stacking height. 9.Increase the feed roller pressure. 10.Replace the worn paper feed roller. 11.Replace the feed roller wheel.
Printing Scumming
1. Reduce the amount of ink transfer (anilox roller). 2. Reduce the bottom pressure. 3. Reduce ink viscosity. 4. Add ink slow drying agent. 5. Clean the printing plate. 6. Improve the abrasion resistance of ink and reduce the pressure of die cutting.
Out of Printing Color Registration
There are several solutions: 1. Check the air pressure, the air pipe of the arm lock cylinder should not leak air, and all the air pipes should not leak air. 2. Adjust the pressure and position of the impression roller. 3. Adjust the parallelism of the impression roller and the printing cylinder. 4. Tighten the ratchets at both ends of the printing plate to make the printing plate tensioned. 5. Adjust the gap between the pulling rollers and cardboard (about 80% of the thickness of the cardboard). 6. Select the appropriate width of cardboard. 7. Check whether the air pipe of the adsorption platform of the printing unit is off, whether the solenoid valve is blocked, and whether the cylinder is normal. Drying the pneumatic system
