Technical Field

The invention relates to the technical field of printing equipment, in particular to a film covering structure of a label printing machine.

Background

Modern printing machines generally comprise mechanisms such as plate loading, inking, stamping, paper conveying (including folding) and the like, and the working principle is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position of the characters and images on the printing plate by manual or printing machine, then it is directly or indirectly transferred on the paper or other printing material (such as textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the same printed matter as the printing plate.

The working principle of the existing printing machine is shown in fig. 4, wherein ink is poured into an ink tank, then a roller rotates to transmit the ink to each roller to form a film covering structure, then a printed product is placed between two rollers, the roller scrapes off redundant ink through a scraper when rotating, a device is started to print a printed pattern on a paper product, most of the scrapers are directly fixed on the device to be in contact with the rollers in the using process of the film covering structure of the existing printing machine, the redundant ink on the rollers is scraped, the rotating speed of the rollers is faster and faster along with the printing of a label, at the moment, hard friction (the scraper is not moved and the roller rotates) begins to occur between the rollers and the scrapers, the rollers wear the contact position of the scrapers, the steel slag falling after the wear falls onto the rollers, the surface of the rollers is not smooth, the label pattern on the surface of a printed product is, and the scraper is struck and is leaned on backward, is not contacting between scraper and the roller, and subsidiary printing ink when the roller rotates, unnecessary printing ink can't strike off on whole printing to the paper article, leads to the label pattern on the paper article to appear on a large scale printing ink, and the unable shaping of label still needs artifical manual correction to get back to initial position, and the printing machine just can normally work, further influences the positive side work of printing machine.
