Water and ink supply area safety protection device for offset machine

Abstract

The invention discloses a safety protection device for a water and ink supply region of an offset press. The safety protection device comprises an active type infrared reflector and a triangular prism arranged on a steel machine frame of the water and ink supply region of the offset press; the safety protection device adopts the combination of an infrared photoelectric technology and a prism emission technology and has low cost and small size in order to increase the range of the water and ink supply region of the offset press and have rapid protection response speed; the application of the triangular prism reflection technology avoids inconvenience of mounting a prolongated wire of a protector; the safety protection device adopts the infrared reflection technology, has rapid response speed in a protection region and simple and convenient mounting, rapidly stops in danger, protects personal safety, is convenient to restart the machine, lightens inert abrading and braking loss of the machine, is convenient for connection of a shutdown control wire nearby, is suitable for safety protection systems of different printing machines at home and abroad or other relevant equipment and radically solves the trouble of personal safety protection of the water and ink supply region of the offset press.

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...

Problems solved by technology

[0004] However, due to the illegal operation of the operator, it is easy to accidentally get the arm or clothes into the drum when there is no stop to add ink or plug the overflow, causing serious injury accidents. Neither the machine operator nor the manager wants to see similar incidents. However, according to statistics, there are thousands of similar injury accidents across the country every year

Since the impression and offset printing cylinders of the offset printing machine are all cast heavy-duty roller wheels with a pressure of thousands of tons, such injuries not only disable the machine operator, but usually destroy the entire machine destructively in order to save the injured limbs. Sawing and dismantling often results in machine damage and casualties, resulting in heavy losses

[0005] In addition, another reason for injury accidents in the water supply and ink supply area of ​​the offset printing machine is that the ink supply mechanism of the machine must be manually cleaned and maintained when going off work every day or when changing to a new printing plate. Working in the near area, a little carelessness can easily cause arms, hair, and clothing to be involved in the imprinting flywheel, causing injury accidents
