Buffering constant-pressure control system of die-cutting machine

Abstract

The invention discloses a buffering constant-pressure control system of a die-cutting machine. The buffering constant-pressure control system comprises reciprocating cylinders, and is characterized in that the four reciprocating cylinders are distributed and fixed on a movable die of the die-cutting machine in a square matrix, and a buffering structure for the lifting motion of the movable die is formed; and the four reciprocating cylinders are respectively communicated with four buffer gas tanks, the gas volume of the buffer gas tanks is more than twice that of the reciprocating cylinders, the four buffer gas tanks are communicated with a precise pressure regulating valve, the precise pressure regulating valve is communicated with an air inlet valve, the air inlet valve is provided with a pressure sensor, and the air inlet valve is provided with a starting threshold value. By means of the buffering constant-pressure control system, stable operation of the whole gas circuit control system is achieved, and motion inertia is eliminated through constant buffering pressure.

Description

technical field [0001] The invention relates to an improved invention of a die-cutting machine, in particular to an improved invention of a buffer constant pressure control system of a die-cutting machine. Background technique [0002] The movable mold of the existing die-cutting machine can be set as an upper mold and a lower mold. During the lifting movement, a spring is usually equipped as a lifting buffer structure. However, due to the limitations of the spring itself, when compressed, the The reaction force of the object will become larger, and the movable mold of the die-cutting machine needs a constant force at the highest point and the lowest point to counteract the inertial force of the movement, so the movable mold of the die-cutting machine will consume more die-cutting at the low point Force to counteract the compression force of the spring, resulting in loss of die cutting force. Contents of the invention [0003] The technical problem to be solved by the pre...
