Abstract

The invention discloses a safety protection device of an automatic die cutting machine, relating to a paper product processing machine. The invention aims at providing a safety protection device with long service life and dual protection functions for an automatic die cutting machine. The technical proposal of the invention is that the safety protection device of the automatic die cutting machine comprises a safety relay, a door-typed safety switch and a normally closed contact in the door-typed safety switch; the door-typed safety switches of all windows and doors are internally provided with two groups of normally closed contacts; wherein, two ends of the circuit connected in series of one group of normally closed contacts are respectively connected with two wiring terminals of the relay; two ends of the circuit connected in series of the other group of normally closed contacts are respectively connected with the other two wiring terminals of the relay; an electromagnetic clutch brake and the series circuit of the normally opened contact of the relays KA1 and KA2 are connected with a DC power supply. The invention is applied to die cutting machines.

Description

Technical field: [0001] The invention relates to a paper product processing machine, in particular to a safety protection device for a die-cutting machine. Background technique: [0002] The automatic die-cutting machine is used for die-cutting and creasing of packaging carton materials, with high speed. In order to facilitate the operator to adjust, maintain and operate the equipment, multiple doors and windows that can be opened and closed are set on the die-cutting machine cover , such as the front cover window door, the transmission side window door of the waste cleaning part, the rear window door of the delivery part, the transmission side window door, etc., the micro switch is installed on the inside of the window door, but this micro switch is easy to be damaged. In addition, each door and window The inner micro switch has only one set of contacts. When one contact fails, the machine can still be started. This single safety protection cannot meet the safety protection...
