Description

Technical Field

[0001] The utility model relates to the technical field of premixing devices, in particular to a raw material premixing device for producing plastic products. Background Art

[0002] The utility model with the publication number of CN215150775U is a raw material premixing device for the production of plastic products. The utility model discloses a raw material premixing device for the production of plastic products. When in use, the conveying motor and the stirring motor are first turned on by the control switch. The conveying motor drives the screening mesh belt to rotate through the conveying roller. At this time, the raw materials are poured into the raw material screening mechanism through the feeding hopper. Qualified raw materials fall to the bottom of the casing through the mesh holes on the screening mesh belt. Unqualified large-particle raw materials follow the screening mesh belt to the conveying end and are discharged from the unqualified material discharge port. Qualified raw materials enter the premixing tank through the first guide pipe and the second guide pipe. The stirring motor drives the stirring shaft to rotate, and the stirring shaft drives the stirring rod to continuously stir the raw materials. At this time, the external hot air blower blows hot air into the premixing tank through the hot air drying air inlet, and the hot air blows to the raw materials through the stainless steel wire mesh to dry the raw materials. The raw materials after mixing evenly are discharged through the discharge port to complete the premixing.

[0003] However, in the above-mentioned raw material premixing device for the production of plastic products, the screening meshes in the raw material screening mechanism are placed in parallel, and no auxiliary screening components are set. The materials are screened only by the mesh holes on the screening mesh belt and gravity. If the materials with larger particles are located below, they will block the mesh holes on the screening mesh belt, causing the qualified materials above to fail to pass through the mesh holes on the screening mesh belt and fall to the bottom of the casing, resulting in low screening efficiency and screening quality.
