A continuous pad printing coding method

Abstract

The invention discloses a continuous transfer-printing coding method. The continuous transfer-printing coding method comprises the following steps: step (a) inking an etching plate by using a sealed oil cup of a transfer-printing coding device; step (b) forwards pushing a rubber head of a transfer printing machine to the upper portion of the etching plate, subsequently driving the rubber head to move down to have contact with the etching plate, and downwards pressing the rubber head to make the rubber head be stained with ink with patterns; step (c) backwards pushing the rubber head to a transfer printing work position, and then driving the rubber head to be pressed downwards so that the rubber head is capable of printing the ink with patterns on a to-be-printed object inside a mold groove; step (d) moving the transfer-printed object to a drying work position for drying by using a conveying component; step (e) moving the transfer-printed and dried object to a coding work position and coding the transfer-printed and dried object by using a laser coding machine. The continuous transfer-printing coding method disclosed by the invention is capable of realizing continuous operation on large-batch to-be-printed objects and improving the production efficiency; the patterns are clearer after the printed objects are dried at the drying work position; a coded product is high in exquisite degree and is fadeless after being used for a long time.

Description

technical field [0001] The invention relates to the technical field of printing technology, in particular to a continuous pad printing coding method. Background technique [0002] Pad printing machine is a kind of printing equipment, which is suitable for printing plastic, toys, glass, metal and ceramics. Pad printing is an indirect intaglio printing technology, which has become a main method for surface printing and decoration of various objects. The whole pad printing process mainly includes several steps of inking, scraping, dipping and pad printing. First, the ink is sprayed on the etching board, and then the excess ink is scraped off with a retractable scraper; The solvent in the ink in the etching area volatilizes and forms a gel-like surface, and then the glue head descends to the etching plate to absorb ink; the glue head absorbs most of the ink on the etching plate and then rises, at this time, this layer of ink volatilizes again One part, the remaining part of th...

Problems solved by technology

[0006] In the pad printing machine and pad printing method disclosed in this patent document, since the surface of the flat plate trans graphic plate is a flat surface, it is relatively easy to grasp the size and position of the graphics formed on it, so the accuracy of pad printing is relatively high, but After the printed object is used for a long time, the ink printed on it is easy to fade and lighten, resulting in poor clarity, and it is difficult to achieve large-scale and continuous pad printing with this pad printing method, and the pad printing efficiency is low
