Problems solved by technology

The powder is mixed with the finished particles, which will cause many problems in the later injection molding production
For example, blockage of the feed inlet of the injection molding machine, rough surface of the injection molded product, blockage of the mold exhaust port, insufficient filling of the product or excessive flash, and decline in the mechanical properties of the product, etc., lead to low production efficiency and low pass rate of the injection molding factory, and then Make it difficult to guarantee the quality of the product

Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] refer to figure 1 , which is a schematic flow chart of an embodiment of the thermoplastic resin granulation method of the present invention. The thermoplastic resin granulation method of the present invention comprises the following steps:

[0035] Step S01, the extruder compositely extrudes the thermoplastic resin and the inorganic filler to form a composite resin;

[0036] The thermoplastic resin and the inorganic filler are proportioned according to the ratio, and they are extruded through an extruder to form a composite resin. In this example, the ratio of inorganic filler to thermoplastic resin is (by mass ratio): thermoplastic resin 20%-40%, inorganic ...

Abstract

The present invention discloses a thermoplastic resin granulation method and a device thereof. The method comprises the following steps: carrying out composite extruding on a thermoplastic resin and an inorganic filler with an extruder to form a composite resin; carrying out bracing water cooling and granulation on the composite resin with a bracing granulation machine to form particles; screening the particles with a screening machine; and separating the particles from the powder with a particle separation device. According to the thermoplastic resin granulation method of the present invention, bracing water cooling, granulation and screening are sequentially performed, and then the particle separation device is adopted to separate the particles from the powder, such that the powder content in the particles is reduced, the powder problem of the downstream injection molding plant during the production process is effectively solved, and the production efficiency and the yield are improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a thermoplastic resin granulation method and equipment. Background technique [0002] Thermoplastic resin (Thermoplastic), because it can be transformed into a solid state and a liquid state under changing temperature conditions, has the advantages of strong processability, compound modification and strong operability, and is widely used in electronics, automobiles, and machinery manufacturing. , daily necessities and other fields. [0003] Thermoplastic resins are mostly used in the field of engineering plastics in the form of composite materials added with glass fiber or inorganic fillers, and in order to enhance strength and reduce costs, the production process of thermoplastic resins is mostly low-cost composite extrusion strand cold-cut granulation model. However, in the cold-cut granulation process of extruded strands, a large amount of powder will be produced d...
