Multi-color and multi-position pad printing machine

Abstract

The invention belongs to the technical field of pad printing and discloses a multi-color and multi-position pad printing machine. The multi-color and multi-position pad printing machine comprises a base, a pad printing assembly arranged on the base in a straddling manner, a plurality of ink feeding assemblies located below the pad printing assembly, a cleaning assembly located in front of the ink feeding assemblies and a material supporting assembly located beside the ink feeding assemblies; the pad printing assembly comprises a horizontally-arranged servo module which is provided with an X movement module capable of moving in the X direction; the X movement module is provided with a first cylinder which drives an adhesive head assembly to move up and down in the Z direction; the adhesive head assembly is provided with pad printing adhesive heads side by side in the X direction, and the number of the pad printing adhesive heads corresponds to that of the ink feeding assemblies; and the material supporting assembly comprises a base, a carrying table located above the base and a third cylinder fixed to the base and driving the carrying table to move in the X direction. The multi-color and multi-position pad printing machine can print colorful patterns formed by combining different color blocks on products, cost is saved compared with a common multi-color pad printing machine, and besides, debugging is easy and fast.

Description

technical field [0001] The invention relates to the technical field of pad printing, in particular to a cost-saving multi-color multi-displacement printing machine. Background technique [0002] Pad printing is a printing technology that uses a silicone rubber head to transfer ink from a printing plate to the surface of a product. It has become a major method for printing and decorating the surface of various objects. The multi-color multi-displacement printing machine is realized on the basis of the single-color ink cup pad printing machine through a special process of taking ink, moving, and dropping ink; the method of use is to put inks of different colors into the multi-color multi-displacement printing machine in each oil cup. When working, the oil cup is fixed, and the printing plate moves back and forth uniformly, and the concave pattern on the printing plate will move in and out of the cup mouth repeatedly. When the concave pattern moves to the inner side of the cup...

AI Technical Summary

Problems solved by technology

[0003] At present, many multi-color pad printing machines move the product in different positions and print inks of different colors respectively. Most of the moving process uses cylinders or more complicated motion control devices; and the printing position cannot be randomly changed as required;
