Problems solved by technology

During the conveying process, the pressure of the paper guide wheel on the cardboard should be maintained at all times, and there will be no printing displacement. As a result, there are always two indentations on the surface of the printed cardboard after the paper guide, and the printing color registration accuracy is not easy. to achieve the desired effect

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0015] like figure 1 , figure 2 As shown, a vacuum adsorption conveying equipment in a water-based printing machine includes a vacuum adsorption box body. The vacuum adsorption box body is composed of an upper cover 1, a lower cover 6, a left side box 2, a right side box 9 and a middle partition. The board divides the vacuum adsorption box into five suction chambers, and the vacuum adsorption box is equipped with a transmission mechanism, a lifting adjustment mechanism and a damper system;

[0016] The transmission mechanism consists of a main drive gear 20, embossing roller 14 and embossing roller gear 13, conveying roller 11, conveying row roller shaft 10 and conveying row roller small pulley 12, synchronous toothed pulley 3, intermediate tr...

Abstract

A vacuum adsorption conveying device in a water-based printing machine relates to the technical field of printing, including a vacuum adsorption box, characterized in that: the vacuum adsorption box consists of an upper cover, a lower cover, a left box, a right box and a middle spacer The middle partition plate divides the vacuum adsorption box into five air suction chambers, and the vacuum adsorption box is provided with a transmission mechanism, a lifting adjustment mechanism and a damper system; the invention can effectively improve the watermarking machine. The color registration accuracy has been improved from ±0.5 to ±0.2mm from the original domestic and foreign ordinary machine color registration accuracy. 2, and the vacuum adsorption transfer can protect the printing screen without reducing the compressive strength of the corrugated cardboard, and at the same time, for some cardboards that have large bending deformation and cannot be printed on the transfer structure of the paper guide roller, it not only plays the role of straightening and The conveying accuracy can also be guaranteed, and finally a multi-color water-based printing product with offset printing effect is printed on the water-based printing slotting and die-cutting machine.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a vacuum adsorption conveying device in a water-based printing machine. Background technique [0002] The conveying of corrugated paper water-based printing slotting die-cutting machine has always been based on the principle of equal linear speed, relying on two pairs of paper guide wheels on a pair of paper guide rollers to transport corrugated cardboard to each position of the unit. During the conveying process, the pressure of the paper guide wheel on the cardboard should be maintained at all times, and there will be no printing displacement. As a result, there are always two indentations on the surface of the printed cardboard after the paper guide, and the printing color registration accuracy is not easy. achieve the desired effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vacuum adsorption conveying d...
