Description

Technical field

[0001] The invention relates to a safety protection system for an offset printing press in the packaging and printing industry, in particular to a personal safety protection device in the water supply and ink supply transmission area of ​​the offset printing equipment. Background technique

[0002] The basic principle of the offset printing machine is to transfer the print pattern to the flexible rubber cloth, and then transfer the pattern on the rubber cloth to the paper to complete the offset printing process. The whole process of printing products on the offset printing press is the imprinting process of the three major cylinders (printing cylinder, blanket cylinder, and impression cylinder) rotating at a high speed. Under the premise of ensuring printing quality, fast printing is the development direction of the industry.

[0003] With the rapid development of industrialization technology, the printing quality and speed of offset printing equipment in the packag...
