Problems solved by technology

[0002] Extrusion granulation is a crucial part in the molding of plastic injection trash cans. In order to achieve the uniformity of granulation, the existing extrusion granulation machines mostly adopt cold cutting type, but they occupy a large area and have sharp granulation edges; The particle size of the die-cutting type is not easy to control, and the specifications of each machine are fixed. If the particle diameter changes, the equipment needs to be replaced, which has great limitations.

Abstract

The invention discloses a garbage can processing process. The process comprises the following steps that (1) a homogenizing liquid is prepared for later use; (2) mixed resin is prepared for later use;(3) hexamethylphosphoric triamide, zinc oxide, silicon dioxide and a flame retardant are mixed, heated and stirred, then the homogenizing liquid is added, and ultrasonic oscillation homogenizing is conducted to obtain a mixed liquid for later use; (4) phenoxyethanol, 1, 2, 3-benzotriazole and a plasticizer are added into the mixed liquid, and uniform stirring is conducted at high temperature to obtain a mixed material for later use; and (5) mixing is carried out, then a mixture is added into a screw extruder to be subjected to extruding granulating, and injection molding is conducted to obtain a garbage can. According to the process, the screw extruder in the step (5) comprises a mounting platform, a transmission case, a feeding mechanism, a driving mechanism, an extrusion mechanism, a cooling circulation structure and a centrifugal drying structure; the angle of an extrusion shaft is manually controlled, the change of various extrusion holes is realized, the extrusion diameter of granules is changed, and the compatibility and the self-adaptability of equipment are improved; and a special-shaped surface end cover ensures uniform particle size and high quality.

Description

technical field [0001] The invention belongs to the technical field of garbage can processing, and in particular relates to a garbage can processing technology. Background technique [0002] Extrusion granulation is a crucial part in the molding of plastic injection trash cans.
