Under the action of the baffle 54, only one set of old net 41 is put into filtering operation. The flow sensor in the processing module 5 corresponding to the old net 41 in use monitors the flow of the cooling liquid in the first-stage liquid outlet pipe 510. When the flow decreases to a preset value, it indicates that the old net 41 in use needs to be replaced. The flow sensor sends a signal to the external terminal, the external terminal receives the signal and controls the driving motor 55 to start, the output shaft of the driving motor 55 drives the round rod 53 to rotate, so that the baffle 54 no longer blocks the inclined processing frame 51 corresponding to the old net 41 not in use, but blocks the inclined processing frame 51 corresponding to the old net 41 in use, preventing the continuous entry of cutting chips and cooling liquid to affect the replacement of the old net 41;
