Abstract

The invention discloses a pneumatic servo positioning device for a filling box in an anti-explosion environment. The device comprises a PLC (Programmable Logic Controller), an electric proportional valve, a gas-gas controller and three groups of action cylinders, wherein a gas source module is connected with a PLC control cabinet and is arranged outside a plant; the PCL control cabinet is connected with an explosion-proof control cabinet in a plant; and the explosion-proof control cabinet is connected with the X-direction cylinder group (4) and the Y-direction cylinder group. Firstly, a PLC receives a position signal, converts the position signal into an electric signal analog quantity and transmits the electric signal analog quantity to an electric proportional valve; then, the electric proportional valve converts the received electric signal into a gas signal and transmits the gas signal to a gas-gas controller; and finally, the three groups of gas-gas controllers control the pushing strokes of the air cylinders in the X direction and the Y direction according to the received gas signals so as to push the box body. According to the device, it is guaranteed that all the box body correcting devices in a plant filled with dust and inflammable gas are not electrified, and the safety problem caused by electrified work of the filling box correcting device in the dangerous environment such as a chemical plant is solved.

Description

technical field [0001] The invention belongs to the field of control technology and automation equipment, and in particular relates to a pneumatic servo positioning device for a filling box in an explosion-proof environment.
