Description

Stamping structure of label printing machine

Technical Field

The invention relates to the technical field of printing equipment, in particular to an embossing 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 figure 4, ink is poured into an ink tank, then a roller rotates to transmit the ink to each roller to form an impression structure, then a printed product is placed between two rollers, the roller scrapes off redundant ink through a scraper when rotating, a starting device can print a printing pattern on a paper product, when the impression structure of the existing printing machine is used, most of the scrapers are directly fixed on the device and are in contact with the rollers to scrape off the redundant ink on the rollers, the rotating speed of the rollers is faster and faster along with the printing of a label, at the moment, hard friction (the scrapers are not moved and the rollers rotate) begins to occur between the rollers and the scrapers, the rollers abrade the contact positions of the scrapers, the abraded steel slag falls into the rollers to cause that the surfaces of the rollers are not smooth, the label patterns on the surfaces of printed products are fuzzy, and the printing quality is influenced, 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.
