s4, the right inductive switch sends a signal to the PLC, the PLC controls an output ejector rod of the water-intercepting cylinder to retract, the left adsorption unit is matched with the flow guide module, the PLC opens an electromagnet of the left adsorption unit and controls an output ejector rod of the right scraper blade cylinder to extend out at the same time, scrap iron attached to the right adsorption water channel is pushed to a right scrap iron box, and the output ejector rod of the right scraper blade cylinder retracts immediately after being completely extended out;
s5, after the interval of preset time, the PLC controls the water-stopping cylinder to enable an output ejector rod of the water-stopping cylinder to extend out and drive the water-stopping plate to be inserted into the U-shaped groove in the water chute, and after the output ejector rod of the water-stopping cylinder completely extends out, the PLC controls an output ejector rod of the push-pull cylinder to retract and simultaneously close the electromagnet of the left adsorption unit, and drives the sliding support to move leftwards until the left induction block is positioned right above the left induction switch;
s6, the left inductive switch sends a signal to the PLC, the PLC controls an output ejector rod of the water-intercepting cylinder to retract, the right adsorption unit is matched with the flow guide module, the PLC opens an electromagnet of the right adsorption unit and controls the output ejector rod of the left scraper blade cylinder to extend out at the same time, scrap iron attached to the left adsorption water channel is pushed to the left scrap iron box, and the output ejector rod of the left scraper blade cylinder retracts immediately after being completely extended out;
s7, repeating the steps S3 to S6, treating the iron chips in the iron chip box which is temporarily idle by an operator in the process, and leading out the cooling liquid by using a water outlet valve on the side surface of the water storage box and sending the cooling liquid back to a machining center for use, so that the whole uninterrupted operation of the chip removing device can be realized.
