Description

A discharge structure of a double-sided printing machine

technical field

The utility model relates to the technical field of printing machines, in particular to a discharge structure of a double-sided printing machine.

Background technique

A printing machine is a machine for printing text and images. A modern printing machine is generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the text and images to be printed The plate is installed on the printing machine, and then the ink is applied manually or by the printing machine to the place where the text and image are on the printing plate, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, etc.) leather, wood, glass and ceramics), so as to reproduce the same printed matter as the printing plate, the invention and development of the printing press played an important role in the spread of human civilization and culture.

During the card printing process, workers first pour various inks into the ink tanks, and each ink tank outputs ink on average through 16 rollers, and the paper feeder feeds a card into the printing machine. The plates are fixed on rotating rollers, the rollers transfer the ink to the printing plate, and the printing plate transfers the ink to the blanket, and the blanket imprints the ink on the paper card as it moves in the printing press. The terminal stacks the printed paper cards flat, and then sends the same paper card back into the printing machine to complete the double-sided printing of the paper card, and then the printed paper card is sent to the combined cutting machine for cutting , but for some long paper cards, when the roller pushes the paper card to move above the conveying wheel, one end of the paper card is slidingly connected with the surface of the conveying wheel on the conveying wheel, and the other end of the paper card is sent out by the roller. The contact end of the wheel is easily affected by external influences, such as machine shaking or wind blowing, which makes the paper card tilt on the conveying wheel, and the roller continues to push out the paper card, which will make the paper card more and more deflected, resulting in the combined cutting machine. When the card is cut, the edge of the cut card is inclined, and the number of defective products increases. For this reason, we propose a discharge structure for a double-sided printing machine.
