Belt wheel type pad printing machine and printing method thereof

Abstract

The invention discloses a belt wheel type pad printing machine. The pad printing machine comprises a machine frame, a printing plate table, a profiling jig and a printing mechanism, wherein the printing plate table, the profiling jig and the printing mechanism are located on the machine frame; the printing plate table is detachably installed on the machine frame and provided with a concave pit used for storing printing ink; the profiling jig is used for fixing a to-be-printed workpiece; the printing mechanism comprises a printing part which is used for sucking the printing ink from the printing plate table and printing the printing ink onto the workpiece, and a first driving assembly which is used for driving the printing part to move between the printing plate table and the profiling jigback and forth; and the printing part comprises a plurality of rotatable roll shafts, and a pad printing belt arranged on the multiple roll shafts in a sleeving mode. The invention further discloses aprinting method of the belt wheel type pad printing machine. Through the belt wheel type pad printing machine and the printing method thereof, high-precision machining is conducted on full size, single-curved surface and multi-curved surface products, the precision is high, and the performance is stable.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a pulley pad printing machine and a printing method thereof. Background technique [0002] Pad printing machine is a kind of printing equipment, which was introduced into our country in the 1980s. The pad printing machine adopts indirect debossed rubber head printing technology, which is suitable for plastic, toys, glass, metal, ceramics, electronics, IC packaging, etc. At present, it has become a main method for printing and decorating the surface of various objects. Because it can print on products with small area and concave-convex surface, it has very obvious advantages, thus making up for the shortage of screen printing, so it has developed rapidly in recent years. [0003] At present, yellow light spraying (spraying + exposure and development) is used in the market for processing, which has high processing costs, low yield, and poor precision, and cannot be applied to hi...
