Screening device for plastic production and using method thereof

Abstract

The invention discloses a screening device for plastic production and a using method thereof. The screening device comprises a feeding port, a machine body is arranged on the outer surface of the lower end of the feeding port, and fixing frames are arranged on the outer surface of one side of the machine body. In the plastic particle screening process, a worker conveys plastic particles into the feeding port through equipment, the plastic particles flow down to screens, the two layers of screens with different meshes are arranged, and thus, screening is facilitated; the plastic particles can be effectively vibrated and screened conveniently when discharged through a vibration device in the using process, and it is ensured that the plastic particles are discharged after being screened by the screens layer by layer; the plastic particles screened layer by layer can be conveniently divided and discharged through a flow dividing and discharging device during using, and disorder after screening cannot be caused; the screens can be conveniently disassembled and cleaned after screening through a rail groove device on one side, and plastic particles are prevented from being left on the screens; and damping springs have the protection and damping effects during vibration screening, supporting frames at the lower ends of the damping springs have the supporting effect, practicability is achieved, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of plastic screening devices, in particular to a screening device for plastic production and a method for using the same. Background technique [0002] The granulation process of the plastic granulator generally includes, extruder feeding, screw extruder extrusion, cold water tank cooling and drawing, granulator granulation, finished product collection, when the granulator cuts the columnar plastic particles, the columnar particles The length of the pelletizing knife is mainly determined by the speed of the pelletizing knife and the cooling condition of the wire drawing, but the water temperature in the cold water tank will fluctuate with the production, so the condition of the wire drawing cooling is unstable, which will affect the length of the columnar particles. In actual production During the process, when the start-up or production conditions fluctuate, the cut particles are long and short. At this tim...

Problems solved by technology

[0005] The present invention provides a screening device for plastic production and its use method, which cannot efficiently solve the problem that the processed raw materials are extruded into strips through an extruder, the regularity of the granular shape cannot be controlled, and there are particles in the granular finished product. Some of them do not meet the usage specifications and cannot be automatically screened, resulting in low production efficiency. It is necessary for the staff to pick out the particles that are too long and then cut them off. The labor load is large, which affects the production quality of plastic particles. The screening of plastic particles is incomplete, lacks accuracy, does not have the effect of splitting materials, has a simple structure, is inconvenient to disassemble, and the screen is not conducive to cleaning. The operation is more complicated, and the degree of automation is lacking, so it is not practical
