Problems solved by technology

[0007] However, the applicant found in the process of using the above-mentioned roller coating equipment assembly that the surface speed of the coating roller and the suction roller is often inconsistent with the process speed of the entire production line, and the entire production line lacks the control of the suction roller and coating roller. The control system for online adjustment of the speed of the cover rollers leads to the frequent need to stop the line for adjustment after the entire production line has been running for a period of time, thereby affecting the efficiency of the entire production line; The surface speed of the roller is inconsistent, which often leads to the inability to transfer the roller coating to the steel plate according to the predetermined position; in addition, in order to print multi-color patterns, it often

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment provides a screen printing production line for patterned steel plates, including a screen printing section for screen printing the steel plate coated with a base color roller, and the screen printing section includes The printing table of the colored roller coated steel plate (steel plate A, which is stacked into a stacking table B after being cut), the bottom of the printing table is provided with a leveling device, the leveling device is used to carry out the surface of the steel plate Leveling before printing.

[0035] In this embodiment, the printing table is a ferromagnetic material printing table, an electromagnetic coil is provided at a position corresponding to the holding position of the steel plate at the lower part of the printing table, and the electromagnetic coil is connected to the energization control device . When this leveling method is used for leveling, the electromagnetic coil is passed through by the energiz...

Embodiment 2

[0054] This embodiment is an improvement on the basis of the screen printing production line of patterned steel plates provided in Embodiment 1. The only difference from Embodiment 1 is that the leveling device is different. In this embodiment, a number of through holes are provided on the printing table at positions corresponding to the holding position of the steel plate, and a fan is provided at the bottom of the printing table, and the fan can pass through the through hole. The hole sucks the wind.

[0055] When this leveling method is used for leveling, since the printing table is provided with a number of through holes, and when the steel plate is uneven, there will be a gap between the steel plate and the printing table. The air can be sucked by the fan. Flow to the fan through the through hole, so that a negative pressure zone is generated at the gap between the steel plate and the printing table, so that the steel plate is adsorbed on the printing table to achieve leveli...

Abstract

The invention provides a screen printing production line of an image coding steel plate. The screen printing production line of the image coding steel plate combines screen printing and roller painting, and not only can obtain accurate underpainting patterns, but also can obtain a thick and strong three-dimension printing layer. Meanwhile, a servo control system which controls rotate speed and starting time of a suction roller and a coating roller of a roller coating equipment element is added at a roller painting section to ensure that actual roller surface line speed is consistent with process rotate speed, accordingly line stopping adjustment is not needed in the process of production, and production efficiency is improved.

Description

technical field [0001] The invention relates to a silk-screen printing production line for pattern-coded steel plates, belonging to the field of pattern-coded steel plate production and manufacturing. Background technique [0002] Screen printing, together with offset printing, embossing printing, and gravure printing, is called the four major printing methods. Screen printing needs screen printing components to complete. Screen printing equipment components are mainly composed of five major elements: screen printing plate, scraper, ink, printing table and substrate. Among them, the screen printing plate is provided with graphic and text Partial mesh and non-graphic part mesh, the mesh of the graphic part can pass through the ink, and the mesh of the non-graphic part cannot pass through the ink. [0003] The basic process of printing with screen printing equipment components is: when printing, pour ink on one side of the screen printing plate, apply a certain pressure on th...
