Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a batching structure for an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics.

[0003] For example, the patent number CN220517417U is an injection molding machine batching structure. The cooperation between the material distribution roller and the material bin can control the proportion of different ingredients by controlling the speed of the first motor to realize automatic batching. The crushing blade can crush larger plastic particle raw materials, so that the raw materials can be mixed more fully. The special-shaped stirring rod located in the middle of the cross bar can stir the raw materials flowing through the middle evenly. The above-mentioned document still has shortcomings. When in use, the cooperation between the material distribution roller and the material bin can control the proportion of different ingredients by controlling the speed of the first motor to realize automatic batching. The crushing blade can crush larger plastic particle raw materials when in use, so that the raw materials can be mixed more fully. At the same time, the chopped raw materials can be added later. The work can also have better integration. When the auger on the left and right sides rotates, the raw materials pre-treated on the inside of the barrel can be transported to the right side for discharge. The special-shaped stirring rod located in the middle of the cross bar can stir the raw materials flowing through the middle evenly. However, when the plastic particles in the barrel are mixed in the batching structure in the above document, the plastic particles in the barrel are mixed by a variety of different plastic particles. The mixing form in the above document is single, which is not convenient for mixing the plastic particles in the barrel evenly during batching, thereby affecting the injection molding effect of the injection molding machine. At the same time, the plastic particles enter the feed hopper from the material bin. The plastic particles are prone to generate static electricity during the feeding process. The plastic particles are attached to the inner wall of the material bin and there will be an overhead phenomenon, thereby affecting the batching of the plastic particles. Utility Model Content
