A bolt 14 is threaded through and connected to the front end of the inner surface of the support frame 13, allowing the bolt 14 to move laterally along the inner surface of the support frame 13 by rotation. The rear end of the outer surface of the bolt 14 is rotatably connected to the front end of the inner surface of the actuating column 15, ensuring that the actuating column 15 does not rotate and that the bolt 14 moves laterally, thus moving the actuating column 15 together.

A collection frame 7 is fixedly connected to the middle of the outer surface of the right side of the filter box 8, so that the scraped metal debris can be collected and stacked by the collection frame 7.

The column 3 and the spring 17 are both provided in two sets, so that the traction frame 16 can move more smoothly when moving laterally.

[0037] Working principle: when using the device, the cooling liquid will be first pumped from the storage tank 5 to the sprayer 4 by the water pump 6, and then the cooling liquid will be sprayed on the centerless grinder 2 by the sprayer 4, and then the excess cooling liquid will flow into the collecting groove 1 and be collected and treated by the collecting groove 1, and then when a certain amount of cooling liquid is collected, the cooling liquid will be discharged along the drain pipe 9 into the filter tank 8, and when the cooling liquid enters the filter tank 8, it will first pass along the surface of the electromagnetic roller 12, so that the metal debris remaining in the cooling liquid is attracted to the electromagnetic roller 12 due to magnetic force, and then when the electromagnetic roller 12 rotates, it will drive the driving column 15 to rotate, so that the driving block 20 on the driving column 15 contacts the inner surface of the traction frame 16, so that the traction frame 16 moves to the left due to the extrusion of the driving block 20, and also drives the rack 19 to move, so that the rack 19 drives the gear 18 to rotate, so that the scraper 11 turns inward and is in contact with the surface of the electromagnetic roller 12, so that the scraper 11 scrapes the surface of the electromagnetic roller 12, and when the driving block 20 stops extruding the inner surface of the traction frame 16, the traction frame 16 will move to the right due to the elastic force of the spring 17, and drive the scraper 11 to turn outward and stop scraping the surface of the electromagnetic roller 12, and then the cooling liquid will flow along the inner surface of the filter tank 8 into the storage tank 5, so as to achieve the effect of circulation.

[0038] When it is necessary to adjust the scraping interval of the scraper 11, the bolt 14 is rotated to drive the driving column 15 to move transversely, so that the two groups of driving blocks 20 on the driving column 15 can contact the inner surface of the traction frame 16, thereby achieving the effect of adjusting the scraping interval of the scraper 11.
