Feeding device for plastic particle production

Abstract

The invention relates to the technical field of plastic particle production equipment, and discloses a feeding device for plastic particle production. The feeding device comprises a mounting base, mounting holes are formed in the periphery of the mounting base, a supporting vertical plate is fixedly arranged at the top of the mounting base, a feeding hopper is arranged at the end, away from the mounting base, of the supporting vertical plate, the feeding hopper communicates with the supporting vertical plate, a discharging inclined plate groove is formed in the side face of the supporting vertical plate, and the discharging inclined plate groove communicates with the feeding hopper. According to the feeding device for plastic particle production, two crushing augers are arranged, so that caked powder can be crushed under the driving of a motor; and the crushing augers expand an arc-shaped collision plate during rotation, so that a screening net vibrates, screening work of powder raw materials is promoted, unqualified powder raw materials are further crushed under the crushing augers, and the purpose of repeatedly screening the powder raw materials is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic particle production equipment, in particular to a feeding device for plastic particle production. Background technique [0002] Modified plastics refer to plastic products that are processed and modified on the basis of general-purpose plastics and engineering plastics through filling, blending, reinforcement, etc., and have improved properties such as flame retardancy, strength, impact resistance, and toughness. Modified plastic parts can not only achieve the strength properties of some steel materials, but also have a series of advantages such as light weight, rich colors, and easy molding. Therefore, the trend of "replacing steel with plastic" has emerged in many industries. It is almost impossible to find a material that can replace plastic products on a large scale. Modified plastic particles are more and more widely used due to the above advantages. [0003] In the use of raw materials for ...

AI Technical Summary

Problems solved by technology

[0003] In the use of raw materials for plastic particle production extruders, powdered plastic raw materials are often used, but because powdered plastic raw materials will absorb moisture in the air during storage, which will cause agglomeration of powdered plastic raw materials. The agglomerated powder raw material is easy to block the hopper when it is poured into the hopper, which seriously affects the production efficiency of the plastic pipe, and some powder plastic raw materials containing large particles of impurities will directly enter the extruder after being directly poured into the hopper inside, which will greatly affect the production quality of clinker particles
