Putty powder raw material feeding and screening device

Abstract

The utility model relates to the technical field of putty powder production, and particularly discloses a putty powder raw material feeding and screening device which comprises a box body, a feeding hopper is arranged at the upper end of the box body, a discharging hopper is arranged at the lower end of the box body, and a screening mechanism for screening and smashing the added putty powder raw material is arranged in the box body. The screening mechanism comprises a discharging assembly moving in a reciprocating mode, two inclined plates which are arranged in a crossed mode are arranged on the lower side of the discharging assembly, the inclined plates incline downwards from the crossed point to the two sides, two screening plates are arranged on the inner wall of the box body and located on the lower sides of the inclined plates, the screening plates incline downwards towards the middle, and the lower ends of the screening plates communicate with a smashing assembly. Through the arrangement of the screening mechanism in the box body, raw materials on the inclined plate are spread flatly and then slide down and fall onto the screening plate to be screened in the reciprocating movement process of the discharging assembly, large-particle raw materials roll into the crushing assembly to be crushed and then are screened, and the raw material screening efficiency and the processing quality are improved.
