[0002] Plastic bottles are usually made of plastics such as polyethylene (PE) or polypropylene (PP). During the manufacturing process, an appropriate amount of organic solvent is added. After being heated at high temperatures, they are made into plastic containers through plastic molds using molding techniques such as blow molding, extrusion blow molding or injection molding.

[0003] At present, the raw materials need to be fully stirred and mixed in the production process of plastic bottles, and some existing raw material mixing devices for plastic bottle production adopt a single mixing and stirring method, usually setting one or more sets of cross bars outside the shaft connected to the drive motor, so that when the shaft rotates, the cross bars will also rotate to achieve a stirring effect. However, this stirring and mixing device cannot evenly mix the vertically layered raw materials when the raw materials are layered, resulting in low mixing efficiency and poor mixing uniformity, which in turn affects the quality of the product.
