Abstract

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.

Description

technical field [0001] The invention relates to the technical field of lowering hoppers, in particular to a raw material lowering hopper for injection molding of disposable lunch boxes. Background technique [0002] Disposable fast food boxes have changed from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated due to their inability to withstand high temperatures and the damage to the environment caused by the production process. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, and degradable lunch boxes have been replaced. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, easy production and relatively low cost, so it has become the mainstream material for manufacturing disposable fast food boxes. Most of the disposable lunch box processing equipment is equipped with The feed hopper is convenient for adding raw materials to the inner cavity of the equipment. The...
