Printing stock detection device and elliptical printing machine

Abstract

The invention provides a printing stock detection device and an elliptical printing machine. The printing stock detection device comprises a printing platen, a support arranged on one side of the printing platen, an image acquisition device arranged on the support and facing the printing platen, a light source and an image processing device connected with the image acquisition device. The printing platen is provided with a light-transmitting part, a supporting face used for supporting a printing stock is formed at the top of the light-transmitting part, the collecting end of the image acquisition device faces the supporting face, light emitted by the light source sequentially penetrates through the light-transmitting part and the supporting face from the bottom of the light-transmitting part, and then the light enters an acquisition end of the image acquisition device. According to the printing stock detection device, damage detection of the printing stock is achieved, the situation that workers need to judge with naked eyes is avoided, manpower and material resources are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a substrate detection device and an oval printing machine. Background technique [0002] On the printing machine, the substrate is a variety of substances that can accept ink or absorb colorants and present graphics. Lay the substrate on the printing platen during operation, and then move the printing platen to the printing mechanism through the driving mechanism for printing operations. If the substrate is damaged, it will cause defective products during printing. [0003] At present, the laying of substrates in the industry is manually operated, and the staff also need to check the substrates during laying. However, for relatively small damages, not only the recognition speed is slow, but the work intensity is high, and misjudgment is prone to occur. Contents of the invention [0004] The object of the present invention is to overcome the shortcomings and deficiencies in th...
