Intelligent paperboard printing method

Abstract

The invention discloses an intelligent paperboard printing method which comprises the following steps that S1, board surface printing is conducted, specifically, a paperboard is placed on a transmission plate, the paperboard moves from left to right along with the transmission plate, a left fan-shaped gear is controlled to be engaged with a toothed plate to drive the toothed plate to move downwards, and a printing plate is pressed downwards to print the surface of the paperboard; S2, board edge cutting is conducted, specifically, a second motor drives a second belt wheel to rotate through a first belt wheel, a rotary disc drives a first short column to rotate, the first short column presses a connecting rod downwards to enable a moving rod to drive a cutter to move downwards, and the cutter penetrates through a cutting groove below the paperboard to cooperate with a cutting table to complete paperboard cutting; and S3, board surface drying is conducted, specifically, an exhaust fan andan air heater are started, clean air is heated through a horn opening and a filter box and then conveyed into a hot air box, and the surface of the cut paperboard is dried through electric fans and air uniformizing holes.

Description

Technical field: [0001] The invention relates to the technical field of cardboard printing, in particular to an intelligent cardboard printing method. Background technique: [0002] Lithography is widely used in the printing of cardboard. It is named after the development of early lithography. In the early lithography, the plates were smoothed with stones and applied, and then improved to metal zinc plates or aluminum plates as plates, but The principle remains the same. There is no difference in height between the printed part and the non-printed part, that is, it is flat. Using the principle of water and oil not mixing, the printed part maintains a layer of oil film rich in oil, while the non-printed part can absorb the printing surface. Appropriate moisture, imagine that after the ink is printed on the plate, the printed part will repel water and absorb the ink, while the non-printed part will absorb water and form an anti-ink effect. The printing method using this metho...

Problems solved by technology

[0003] When the cardboard is lithographically printed, cutting the edge of the board is one of the important technological processes. The technological process in the prior art is to set a cutter at the discharge port to cut the cardboard. This cutting method belongs to pre-processing, and the cardboard is pressed and cut. The adjacent cardboards are still stuck together and need to be broken manually, which reduces the automation standard of industrial production; in the traditional cardboard printing method, there is no drying method in the production steps, and the ink cannot be dried in time after printing, which is easy to cause the ink to be broken. Permeation and diffusion on the cardboard, the accumulation of a large number of processed cardboards will affect the molding quality of the pattern
