[0017] Working process of the present invention: During the working process of the present invention, the sorting plate sorts the bolts into rows for transmission. When the bolts are transported to the bottom of the cleaning net cylinder, the electromagnet of the station strongly adsorbs the bolts, and the bolts are adsorbed onto the cleaning net cylinder. Then the bolts are rotated into the auxiliary wind hood. When the bolts are located between the auxiliary wind hood and the strip groove, the controller adjusts the suction force of the electromagnet so that its magnetic force can only adsorb iron filings but not the bolts. The bolts can fall naturally under the action of gravity, and the auxiliary wind hood blows air to the bolts. The iron filings on the surface of the bolts are blown down and enter the chip storage space, and are adsorbed to the surface of the mounting cylinder. The chip suction holes exhaust air to generate negative pressure in the chip storage space. When rotating to the discharging station, the bolts fall into the material receiving box through the material guide inclined plate.
[0018] When cleaning chips, the electromagnet is powered off, the mounting cylinder loses its adsorption force, and the iron chips fall to the bottom of the chip storage space, and the dust suction pipe sucks away the iron chips at the bottom; when the mounting cylinder rotates, the cleaning ring plate rotates accordingly, the right baffle does not rotate, and the sliding block rotates along the circular track. When cleaning, the telescopic cylinder extends, and the cleaning ring plate is extended into the chip storage space, which can automatically clean the chip storage space.
[0019] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
