Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding equipment, in particular to a plastic cup batching device. Background Art

[0002] Plastic injection molding is a method of producing plastic products, which involves injecting molten plastic into a plastic product mold under pressure, cooling and molding to obtain the desired plastic parts. In the normal injection molding process, after the product is injected, there will be some waste due to the existence of runners and glue inlet points. Under normal circumstances, the waste is generally collected by a material frame, and then after unified collection, it is uniformly crushed and recycled again.

[0003] In existing plastic injection molding workshops, recycled waste plastic materials and plastic materials to be injected are usually crushed by crushers respectively, and then the crushed particles of recycled plastic and the crushed particles of plastic to be injected are mixed in a certain proportion to form a mixed plastic ingredient, and the mixed plastic ingredient is used as injection molding raw material particles, which are injected into plastic product molds by a pressure injection molding machine for injection molding.

[0004] The traditional mixing method is to manually weigh the required weight of the recycled plastic and the plastic to be injected, then stir the recycled plastic and the plastic to be injected to mix them evenly, and finally pour the mixture into the storage hopper of the injection molding machine, and finally use the pressure injection molding machine to inject it into the plastic product mold for injection molding. In the above method, the batching accuracy is not high and the mixing is not uniform, which affects the quality of plastic injection molding and causes a low pass rate of injection molded products. In addition, during the batching and stirring process, there will be a certain amount of dust in the plastic particles, which will cause environmental problems. Utility Model Content
