Description

Technical Field

[0001] This utility model belongs to the field of plastic film processing technology, and in particular relates to a mixing device for film preparation. Background Technology

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. When recycling and reprocessing plastic film, it needs to be mixed with additives.

[0003] The publication (announcement) number CN211541909U discloses a mixing mechanism for agricultural plastic film processing, including a fixed base, a drive motor on one side of the top of the fixed base, a mixing barrel fixedly connected to the fixed base on one side of the drive motor, a cover plate on the top of the mixing barrel, a discharge plate on the side of the mixing barrel, a drive wheel fixedly connected to the free end of the output shaft of the drive motor, and a positioning shaft inside the fixed base. This invention achieves omnidirectional mixing of the material through the axial rotation of the mixing blades, accompanied by the longitudinal tumbling of the material, resulting in a better mixing effect and facilitating further processing of the material.

[0004] During use, it was found that the mixing mechanism suffers from severe wear at the bottom because the mixing blade 11 rotates in close contact with the inclined plate 12. Regular replacement of the mixing blade 11 is necessary. Furthermore, since the mixing blade 11 is installed relatively low in the mixing tank 3, materials with significant density differences tend to stratify after feeding. This means that during rotational mixing, the mixing blade 11 can only stir the lower layer of material, resulting in insufficient and uneven mixing and reduced efficiency. Therefore, a mixing device for thin film preparation needs to be designed to address these issues. Utility Model Content
