The shell is made of a variety of materials, including plastic, stainless steel, tempered glass, etc. The plastic shell is produced by injection molding, and the raw materials used in injection molding need to be made through a proportioning device.

[0003] At present, in the process of proportioning the raw materials used for injection molding of water purifier shells, the staff is required to weigh each raw material according to the proportion in advance, and then add them one by one into the mixing tank for stirring and mixing. The proportioning efficiency is low. Therefore, we propose a raw material proportioning device for injection molding of water purifier shells. Utility Model Content

[0004] The purpose of the utility model is to provide a raw material proportioning device for injection molding of a water purifier shell. The device has the advantages of being able to simultaneously and automatically put a variety of raw materials into a stirring tank according to the proportions during the proportioning process of the raw materials for injection molding of the water purifier shell, thereby improving the efficiency of raw material proportioning and reducing the labor intensity of the staff. It solves the problem that in the current proportioning process of the raw materials used for injection molding of the water purifier shell, the staff is required to weigh each raw material according to the proportion in advance and then add them one by one into the stirring tank for stirring and mixing, resulting in low proportioning efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a raw material proportioning device for injection molding of a water purifier shell, comprising a base and a PLC, a stirring tank and a fixed seat are fixedly installed on both sides of the upper surface of the base, a feed hopper is fixedly installed on one side of the upper surface of the stirring tank, a column is rotatably installed on the upper surface of the fixed seat, a slide groove is provided on the outer surface of the column, a screw rod is rotatably installed inside the slide groove, a threaded slider is movably sleeved on the outer surface of the screw rod, a cross plate is fixedly connected to the outer surface of the threaded slider, a number of weighing plates are equidistantly fixedly installed on the upper surface of the cross plate, a storage box is fixedly installed on the upper surface of each weighing plate, an electric valve is fixedly connected to the lower surface of each storage box, and a discharge pipe is fixedly connected to the end of each electric valve.
