Description

Quick feed hopper that reloads Technical Field The application relates to the technical field of blanking of injection molding machines, in particular to a blanking hopper capable of rapidly changing materials. Background In the plastics production industry, injection molding machines are often equipped with high capacity hoppers to meet continuous production requirements. The hopper has large capacity and fixed structure, and can ensure the production efficiency. However, the large-capacity discharging hopper is huge, so that the flow condition of materials in the discharging hopper is not easy to observe. In the process of equipment debugging, the material state is required to be frequently observed, the formula or the technological parameters are required to be adjusted, and the material flow condition is difficult to see clearly, so that an operator is difficult to accurately grasp the actual state of the material, and further correct adjustment cannot be timely made.
