A gas-hydraulic pressurized die-cutting machine control device

Abstract

The invention discloses a regulating and controlling device of a gas-liquid booster-type die-cutting machine. The regulating and controlling device of the gas-liquid booster-type die-cutting machine is characterized by comprising the gas-liquid booster-type die-cutting machine, a flow regulating device arranged between the gas-liquid booster-type die-cutting machine and a gas source and used for regulating gas inlet flow of the gas-liquid booster-type die-cutting machine in real time, a flow detecting unit used for detecting the gas inlet flow of the gas-liquid booster-type die cutting machine in real time and a control device receiving the real-time gas inlet flow, output by the flow detecting unit, of the gas-liquid booster-type die-cutting machine and used for controlling the flow regulating device to adjust the gas inlet flow of the gas-liquid booster-type die-cutting machine in real time according to a difference value between set gas inlet flow and the real-time gas inlet flow of the gas-liquid booster-type die-cutting machine. The regulating and controlling device of the gas-liquid booster-type die-cutting machine achieves digital automatic control in the die-cutting pressure regulating process and particularly in the booster process.

Description

technical field [0001] The invention relates to a die-cutting drive mechanism of a die-cutting machine, in particular to a gas-liquid pressurized die-cutting machine control device. Background technique [0002] As the main equipment for realizing die-cutting and creasing, die-cutting machine plays an irreplaceable and important role in the packaging and printing industries. The die-cutting drive mechanism of the traditional die-cutting machine uses a switch-type reversing valve with a low operating frequency to control the on-off of the air circuit, the pressure-reducing valve is used to adjust the required pressure, and the throttle valve is used to adjust the required flow rate. If you want to have multiple output forces and multiple motion speeds, you need multiple pressure reducing valves, throttle valves and reversing valves. In this way, not only many components are required, the cost is high, and the system is complicated, but also many in the actual work process. T...

The die-cutting driving mechanism of the traditional die-cutting machine uses a switch-type reversing valve with a low action frequency to control the on-off of the air circuit, the pressure-reducing valve is used to adjust the required pressure, and the throttle valve is used to adjust the required flow rate. If you want to have multiple output forces and multiple motion speeds, you need multiple pressure reducing valves, throttle valves and reversing valves. In this way, not only many components are required, the cost is high, and the system is complicated, but also many in the actual work process. The components need to be manually adjusted in advance, and there are disadvantages such as difficult processing and assembly, easy wear, and high noise, and the digital control of the working pressure of the die-cutting system cannot be realized.
