Raw material automatic batching and mixing device for PVC film production

Abstract

This utility model relates to the field of mixing device technology, specifically an automated batching and mixing device for PVC film production. The utility model includes a mixing tank with a feed inlet fixedly installed on the upper outer side and a discharge pipe located on the lower outer side. The utility model features a multi-layered, three-dimensional mixing structure with a main stirring rod at the center and three auxiliary stirring rods distributed around it. When the main rod rotates, it shears and flips the central area of ​​the PVC raw material, while the auxiliary rods simultaneously act on the edge areas, eliminating blind spots in the mixing of PVC raw materials. Compared to traditional single-shaft mixing equipment, this avoids the limitation of a single stirring shaft forming only a limited mixing path and material flow area, which makes it difficult for raw materials to quickly and fully contact and blend during mixing. The combination of one main stirring rod and three auxiliary stirring rods creates multi-directional mixing force, significantly improving the uniformity of material mixing.

Description

Technical Field

[0001] This utility model relates to the field of mixing devices, specifically an automated batching and mixing device for raw materials used in PVC film production. Background Technology

[0002] The automated batching and mixing equipment for PVC film production is mainly used to automatically batch and mix various raw materials required for PVC film production, such as PVC resin, plasticizer, stabilizer, and filler, in precise proportions. PVC film has a wide range of applications, and demand continues to grow in industries such as construction, packaging, electronics, and automobiles.

[0003] In the current technology of raw material mixing in PVC film production, the traditional equipment operates by having the raw materials enter the mixing chamber through the feed inlet and relying on the stirring shaft to drive the stirring blades to mix the raw materials inside the chamber. However, since these mixing equipment generally adopt a single-shaft stirring structure, in actual production, a single stirring shaft can only form a limited stirring path and material flow area, making it difficult for the raw materials to quickly and fully contact and blend with each other during mixing, thus limiting the efficiency of material mixing and failing to meet the needs of high-efficiency production.
