Cutting apparatus comprising a door gas cleaning device

Abstract

The present application discloses a cutting apparatus, including: a housing; a door; and a gas cleaning device configured to receive a cleaning gas through the gas inlet and blow the cleaning gas out of the at least one primary gas outlet towards the door to clean the door. The present application uses a gas cleaning device to clean the door, and a gas curtain formed by cleaning gas causes a cutting coolant, chips and sand particles, etc. attached to the cutting door to drip down to a baffle and then return to an operating cavity. Moreover, by controlling the blow-out angle and pressure of the cleaning gas, the cutting coolant, chips and sand particles, etc. can be retained within the range of the operating cavity without dripping onto the outside of the cutting apparatus. Furthermore, as the door is opened, the door moves relatively with the gas cleaning device such that the process of the gas cleaning device cleaning the door is substantially synchronized with the process of opening the door, and no further liquid drips onto the workbench or the ground from the portion of the door passing the gas cleaning device.
