Description

Explosion-proof system and polisher Technical Field The application relates to the technical field of machining, in particular to an explosion-proof system and a polisher. Background In the related art, a polisher is widely used for finish machining and surface polishing treatment in the mold industry. However, a large amount of dust is easily generated during the polishing process of the polisher, and at this time, if an electric appliance of the apparatus operates to generate an arc, a mechanical spark or flame to generate a fire source point at a high temperature, there is a hidden danger of explosion. Disclosure of utility model The embodiment of the application provides an explosion-proof system and a polisher with the same, which are used for solving at least one technical problem. An explosion protection system of an embodiment of the present application is for a sander having a working chamber, the explosion protection system comprising: a fire extinguisher comprising a pressure valve; a driver coupled with the pressure valve; A detection assembly configured to detect an environmental parameter within the working bin; And the controller is electrically connected with the driving piece and the detection assembly respectively and is configured to control the driving piece to drive the pressure valve to open the fire extinguisher when the environmental parameter meets a first preset condition. According to the explosion-proof system provided by the application, the condition in the working bin of the polisher is monitored through the detection component, and the fire extinguisher is driven to be opened in time to eliminate the fire source when the fire source possibly causes explosion, so that the explosion is avoided, and the safety of equipment is improved. In certain embodiments, the drive member comprises a bracket mounted on the fire extinguisher and an electric cylinder comprising a cylinder body mounted on the bracket and a drive end coupled to the pressure valve.
