Automatic screening and feeding device for large and small steel balls

Abstract

The invention discloses an automatic screening and feeding device for large and small steel balls, and belongs to the technical field of material sorting. The automatic screening and feeding device comprises an automatic stock bin, a feeding mechanism and a ball cutting mechanism which are connected in sequence, the automatic stock bin comprises a stock bin body and a cavity plate, and a feed portof the cavity plate is slidably connected to a discharge port of the stock bin body; and the feeding mechanism comprises a material distributing plate, the feeding end of the material distributing plate is connected to a discharging port of the cavity plate, the material distributing plate comprises a small ball trough and a large ball trough arranged at the upper end of the small ball trough, and the small ball trough and the large ball trough are provided with a small ball discharging port and a large ball discharging port correspondingly. Compared with the prior art, automatic feeding, distributing and supplying of the large steel balls and the small steel balls can be achieved, and scratches caused by excessive friction between the steel balls in the feeding, distributing and supplying process are avoided; and the sorted steel balls can automatically enter the corresponding steel ball recovery barrels.

Description

technical field [0001] The invention relates to the technical field of material sorting, in particular to an automatic screening and feeding device for large and small steel balls. Background technique [0002] At present, the exhaust emission standards of domestic automobile manufacturers have been upgraded from China V to China VI. In response to the new emission standards, the design of the car is to increase the pressure of the gasoline oil circuit, the better the atomization effect of the gasoline sprayed by the injector, the more fully the engine burns, and the less exhaust emissions. The automotive fuel injector is actually a switch valve function, which can control when gasoline is injected into the engine for combustion. Its sealing depends on the tight contact between the spherical surface of the steel ball at the top of the valve stem and the conical surface of another part. Due to the increase of the oil pressure of gasoline, in order to meet the sealing require...
