Transfer printing machine and transfer printing method

Abstract

A transfer printing machine comprises the following components: a transfer printing wheel, an ink supply device, a material collecting / discharging roller set, a pressure wheel, a lifting platform, a panel type reverse pattern plate and an ink eliminating device. The ink supply device is used for supplying ink to the transfer printing wheel. The material collecting / discharging roller set is used for supplying a continuous printing material, wherein the continuous printing material is clamped between the transfer printing wheel and the pressure wheel. The lifting platform is provided above the transfer printing wheel and can vertically move relative to the transfer printing wheel. The panel type reverse pattern plate is equipped on the lifting platform and can move frontwards and backwards relative to the transfer printing wheel, thereby removing partial ink on the transfer printing wheel. The ink eliminating device is used for eliminating the ink on the panel type reverse pattern plate. According to the transfer printing machine, as the surface of the panel type reverse pattern plate is a flat surface, the dimensions and positions of the patterns which are formed whereon can be easily mastered. High-precision requirement can be satisfied. Furthermore when the dimensions of the patterns of the panel type reverse pattern plate is more precise, a better product quality can be obtained.

Description

technical field [0001] The invention relates to a pad printing machine and a pad printing method, in particular to a pad printing machine and a pad printing method using a flat plate reverse graphic plate combined with roll printing. Background technique [0002] see figure 1 , figure 1 It is a schematic diagram of a pad printing machine 1 of the prior art. Such as figure 1 As shown, the known pad printing machine 1 includes a pad printing wheel 10 , an ink supply device 12 , a feeding and discharging roller set 14 , a pressing wheel 16 and a reverse pattern wheel 18 . The ink supply device 12 is used for supplying ink to the pad printing wheel 10 . The feeding and unwinding roller set 14 is used to provide a continuous printing material 20 , wherein the continuous printing material 20 is clamped between the pad printing wheel 10 and the pressing wheel 16 . Generally speaking, the reverse pattern wheel 18 has a pattern formed by engraving or etching. When using the pad...

AI Technical Summary

Problems solved by technology

[0003] Since the surface of the reverse graphic wheel 18 used to remove ink is a curved surface, the graphics formed by engraving or etching cannot meet the requirements of high precision, and it is difficult to grasp the size and position of the graphics

In addition, when the size of the pattern on the reverse pattern wheel 18 is relatively fine (for example, on the order of several microns), the contour of the pattern printed on the continuous printing material 20 will have obvious waves, which will affect the quality of the product.
