Description

Technical Field

[0001] The utility model relates to the technical field of injection molding tooling, in particular to a quick material-changing silo. Background Art

[0002] At present, in the injection molding industry, all raw material particles need to be processed and formed by equipment after modification to test the various properties of the modified materials, so as to continuously improve the formula and finally meet the designed requirements. However, since the amount of raw material particles used in the test is very small and the replacement frequency of raw material particles is quite high, the raw material particles need to be frequently replaced in the silo on the injection molding equipment. Since the raw material particles placed in the current silo have only one outlet to the injection molding equipment, when replacing the raw material particles, the replacement process is cumbersome and complicated. The raw material particles need to be taken out of the silo manually, which is very difficult. Some silos are installed at a high position and need a stepladder, while some silos are deep and cannot be reached by hand. Therefore, it is urgent to design a new silo to meet the requirements of rapid replacement of raw material particles in the silo. Utility Model Content

[0011] Beneficial effects of the present invention:

[0012] The utility model provides a fast material change silo. The silo stores materials. When changing materials, the discharging device needs to be opened to discharge the materials. If the material is changed during the normal operation of the production line, the operator needs to stand on the main machine and use a digging scoop to dig the materials out of the silo, which leads to slow material change speed and high labor intensity during the production process. After the transformation, the silo materials are directly discharged from the position of the material change device, and the material discharge port does not need to be moved during the process. The normal production of the production line is not affected during the material change process. The material change process and the material discharge process can be carried out at the same time, so as to improve the material change efficiency and reduce the labor intensity of employees.
