Description

Technical Field

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

[0002] In the plastics processing industry, the uniformity of plastic granule mixing directly affects the product quality of subsequent molding processes such as injection molding and extrusion. Granule screening and pretreatment at the feeding stage are crucial preliminary steps to ensure effective mixing. During production, storage, and transportation, plastic granules are prone to contamination with impurities, clumps, or oversized irregularly shaped granules. If these directly enter the mixing equipment, they can lead to uneven granule dispersion, impingement jamming, equipment wear, and even affect the mechanical properties and appearance of the final product. Therefore, existing plastic granule mixing equipment typically incorporates a screen structure at the feed inlet to intercept impurities and substandard granules, achieving initial purification of the raw materials.

[0003] Most existing plastic pellet mixing equipment uses a fixed-aperture, one-piece screen for the feed inlet. Plastic product processing requires the adaptation of various specifications of plastic pellets, and some mixing processes require adjustment of the pellet size ratio according to the formula. Fixed screens cannot flexibly adapt to dynamically changing screening needs. If the screen aperture is smaller than the required pellet size, it will cause raw materials to accumulate and block the feed inlet. If the aperture is too large, it cannot effectively intercept impurities and unqualified particles, thus losing the purpose of screening.

[0004] Therefore, it is necessary to provide a new plastic pellet mixing equipment for processing plastic products to solve the above-mentioned technical problems. Utility Model Content
