Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic film production, in particular to an aluminum-plastic film polymer raw material extrusion mixing device. Background Art

[0002] Aluminum-plastic film is mostly used in the packaging field. It can ensure that the humidity in the packaging bag is lower than 40RH. The moisture-proof effect is 80 times that of ordinary polyethylene. Composite films of various specifications, sizes and materials are available. It has good protective properties, oxygen barrier, moisture-proof, puncture resistance, high strength, high toughness, one-way or two-way breathable, UV resistance, and chemical resistance, such as oil, grease and acidic and alkaline substances.

[0003] Aluminum-plastic film is composed of a variety of polymer materials and aluminum foil, among which polymer materials are generally polymer composite materials, which are made by mixing and extruding two or more polymer raw materials. Extruders are generally used as extruders, and most extruders are screw extruders. After searching, it was found that the publication number is CN214726311U, and the name is a plastic extrusion device based on a polymer material export mechanism. The application proposes that the extruder occupies a very important position in the polymer production process. Basically, every polymer factory needs to be equipped with an extruder. However, the existing polymer material mixing extrusion device has a poor mixing effect during use, and there is no screening mechanism, which may cause uneven mixing and lead to poor product quality. By setting a vibrating screen to The rotating shaft and stirring blades are arranged in the feed bin to stir the raw materials to ensure that the raw materials are mixed with each other. The mixed raw materials enter the vibrating screen, so that the raw materials are automatically screened to ensure the uniformity of the product, and then enter the extrusion barrel through the vibrating screen, so as to further perform the mixing compression and extrusion to ensure the quality of the product. However, this application adopts the operation of mixing first and then screening. Since the polymer raw materials need to determine the mix ratio when extruding, therefore, the weight ratio of each material needs to be determined before mixing. Screening after mixing can easily cause some raw materials that do not meet the particle size to be screened out, which can easily lead to incorrect mix ratios, affecting product quality, and further affecting work efficiency. At the same time, this application also requires staff to manually operate the baffle, which is more troublesome and can be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
