When the filter screen on the surface of the filter cartridge 613 is blocked, the cooling liquid cannot flow into the filter cartridge 613 at this time, and the pressure of the cooling liquid in the liquid inlet groove 614 increases, which drives the piston body 612 to slide to the left and drives the guide rod 618 to move to the left, triggering the point switch 619 to start and driving the warning light to start operation, so as to effectively monitor the blocking state of the filter assembly 6 and ensure the filtering efficiency of the cooling liquid.

[0046] When the piston body 612 moves to the left, the cooling liquid flows from the position between the piston body 612 and the filter cartridge 613 to the through hole two 617, and then flows into the filter cartridge 613, and then is discharged from the liquid outlet pipe 616, so as to avoid the phenomenon that the cooling liquid pressure in the liquid inlet pipe 621 and the through cylinder 622 instantaneously increases in the state that the pump body 316 does not stop, and avoid the influence on the use quality.

[0047] When the flow of the cooling liquid used by the cutting machine tool changes, the flow rate of the cooling liquid is effectively detected by the detection assembly 2 in the specific implementation of the present application. The detection assembly 2 drives the control assembly 5 to act and adaptively adjusts the rotating speed of the electromagnetic speed regulation motor 312, so that the rotating speed of the magnetic cylinder 313 is adapted to the flow rate of the cooling liquid, the phenomenon that the waste chip adsorption time of the magnetic cylinder 313 is reduced is avoided, the waste chip is scraped off by the scraper 314 and falls into the vibrating guide chute 315 by gravity when the cooling liquid flows through the rotating magnetic cylinder 313 and is adsorbed on the surface of the magnetic cylinder 313 by the magnetic force of the magnetic cylinder 313, and finally the waste chip is collected by the collecting frame, so that the separation efficiency and requirement of the waste chip are improved.
