The invention discloses a
raw material feeding hopper for injection molding of a disposable lunch box. The
raw material feeding hopper comprises a feeding hopper, the tops of two sides of the inner cavity of the feeding hopper are fixedly connected to
cushion blocks, the top of the
cushion block is provided with a filtering plate, two sides of the filtering plate are provided with clamping slots,a clamping rod is arranged in the inner cavity of the clamping slot, one end, far away from the inner cavity of the clamping slot, of the clamping rod passes through the feeding hopper and extends toout of the feeding hopper, one end, outside the feeding hopper, of the clamping rod is fixedly connected to a connection plate, and the inner wall of the
cushion block is fixedly connected to a spring. The
raw material feeding hopper filters raw materials and prevents impurities from entering the
processing equipment. The filtering plate is easy to disassemble and clean. Through cooperation of a connection block, a baffle, a chute, a sliding plate, a threaded hole and a
threaded rod, the
diameter of the inner chamber of the feeding hopper can be adjusted according to demands of a user, thus the feeding flow of the raw material is adjusted, the feeding rate is controlled and the orderly
processing of raw materials is achieved.
