Printing machine capable of positioning and correcting printing patterns in multiple sizes

Abstract

The invention discloses a multi-size printing machine for positioning and correcting printed patterns, which comprises a workpiece table, two supporting rods which are symmetrical left and right are fixedly arranged on the workpiece table, a lifting plate is arranged between the two supporting rods in a sliding manner, a sliding block cavity is formed in the bottom surface of the lifting plate, a sliding block is arranged in the sliding block cavity in a sliding manner, and a printing block is fixedly arranged on the bottom surface of the sliding block. A hot stamping wheel is rotationally arranged on the printing block, two sliding plate cavities in bilateral symmetry are formed in the workpiece table, correction cavities are formed in the bottom walls of the two sliding plate cavities, two left-right alignment correction sliding plates are arranged in the correction cavities in a sliding mode, and two push plate cavities in front-back symmetry are formed in the faces, close to each other, of the two correction sliding plates. According to the automatic positioning device for the standard part, the standard part can be automatically positioned, a workpiece can be corrected and positioned for multiple times through infrared rays according to the overall dimension of the standard part, and therefore it can be ensured that the workpiece is accurately placed at the position aligned with the standard part without errors.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a printing machine for multi-size positioning and correcting printing patterns. Background technique [0002] A printing press is a machine that prints text and images. Its principle is to make a printing plate with the text and images to be printed, install it on the printing press, and then manually or the printing press apply ink to the place where the text and images are on the printing plate. Then transfer directly or indirectly to the substrate, so the substrate needs to be positioned and corrected during the printing process; [0003] Different substrates of the printing machine are different in size, size and specification, and it is difficult for a single type of positioning device to quickly position and correct the substrate. The calibration and positioning device of the bag printing machine uses a transfer plate to load the plastic woven bag, and then the w...

Problems solved by technology

[0003] Different substrates of printing machines are different in size, size and specifications, and it is difficult to quickly position and correct the substrate with a single type of positioning device. The correction and positioning device of the bag printing machine, which uses the transfer plate to load the plastic woven bag, and then fixes the woven bag through the deflection rod, the fixed block and the transfer plate, but for plastic woven bags of different sizes, it is still necessary to manually adjust the plastic woven bag. Only by adjusting the position on the conveying plate can the printing and fixing position of the plastic woven bag be finally determined, which is troublesome to operate

[0004] Moreover, if there is an error in the positioning correction of the substrate, it is easy to cause a collision between the printing device and the substrate, resulting in damage to both the substrate and the printing device. At the same time, due to the deviation of the position of the substrate, the printing position is inaccurate and affects the appearance of the substrate.
