"Dropping" refers to the phenomenon that dust adhering to the printing machine vibrates during the operation of the machine to cause dust agglomeration to fall on the surface of the printed matter. However, after printing, such as printed albums, leaflets, hangtags, color boxes, and handbags, which have large areas of ink, they are cleaned with air guns. It seems that there is no dust but it will fall off during printing, so the printing machine is high speed after cleaning. After five minutes of idling, the dust is completely dropped; at the same time, the glass around the paper discharger is not attached to the dust. The number of sweeps is related to the amount of print time spread, once a day; if it is continuously operated for 24 hours, twice a day. In addition, in the case of PP coating and subsequent processing, in order to be cautious, cleaning is first performed to control the amount of dispersion.
1. Cleaning place:
2. Around the spout;
3. Anti-static pipe;
4. Fans and paper dischargers everywhere;
5. The two sides of the lift.
6. Use an air gun and brush for cleaning.
The place where the flying dust is easy to adhere, the spout portion of the spreader and the nozzle around the spout. There are eight outlets for the full press.
Inside and around the electrode of the antistatic device that is placed side by side with the paper discharger.
A part of the small fan of the paper discharger and the surrounding.
The two sides of the lifter of the paper discharger. When the lifter is lowered, the track tends to adhere to the dust, and the more the paper is piled up, the easier it is to drop large pieces of dust.
Avoid the powder, inhibit the flying, use a small amount of powder to solve the back printing, and easy to clean the hydrophilic UP800 is our recommended.
We feel that it is not a simple matter to solve the problem of residual surface of printed matter caused by powder falling, and it is not easy to develop powder that is not easy to adhere to machinery. It is impossible to completely solve the problem of powder falling. There is no best way to solve the problem of powder drop, except for cleaning machinery.
