In a common way, the printing mechanism provided with anilox rollers is formed as a carrier, the replacement and adjustment is performed on the carrier, and then the whole carrier is mounted on the production line, so that the following drawbacks exist:

1) The weight of one carrier is heavy, the operation is very inconvenient in the process of transferring and aligning, and the carrier needs to be further adjusted after being installed, so that the carrier is very laborious, the forming precision cannot be guaranteed, and a long time is required;

2) After the anilox roller is installed, the angle and the position of the scraper are further required to be adjusted, the size of an ink storage area formed by the angle of the common scraper module is uncontrollable, and meanwhile, along with the rotation of the metal anilox roller, ink can shake in the area, so that relatively uniform ink supply is difficult to realize, and the ink carrying capacity cannot meet the printing requirement (insufficient ink supply often occurs); and because the probability of ink leakage from the end part caused by shaking is high, the ink ribbon is added to the actual control, so that great inconvenience is brought to the actual control.
