Stress-resistant plastic part processing technology

Abstract

The invention discloses a stress-resistant plastic part machining technology. The stress-resistant plastic part machining technology comprises the following steps of: a, mixing: mixing ethylene-hexene copolymerized polyethylene resin, an antioxidant, an auxiliary antioxidant and a release agent; b, compounding: compounding the mixture in the step a; c, cooling: cooling the mixture extruded in the step b; and d, pelletizing: pelletizing the mixture in the step c. A cooling tank in the step c comprises a main body, a material opening, a cooling cavity, a transfer roller, a transfer spring, a flow guide cylinder, a flow guide device, a drying cavity, a fan, a drying device, a rotating wheel, a first collecting belt, a collecting spring, a second collecting belt, a second motor, a driving cylinder, a scraper blade, an opening and a water removal mechanism. According to the stress-resistant plastic part machining technology, the stress resistance of the plastic can be improved, so that the comprehensive mechanical property of the plastic is higher. The cooled mixture is dried, so that the washed impurities in cooling water can be removed, and the quality of the plastic is improved. Impurities in the drying cavity are automatically cleaned during drying, so that the cooling and drying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a processing technology of stress-resistant plastic parts. Background technique [0002] At present, plastics have been widely used in the fields of construction, packaging materials, household daily necessities, and automobiles; due to different working environments, there are high requirements for the comprehensive mechanical properties of plastic parts; when making plastics, the raw materials are passed through a mixer The mixing obtained after mixing needs to be cooled and then pelletized to obtain plastic products; in the existing cooling technology, most of them use the mixing directly to the static water for cooling; but this method will make the water temperature uneven, The cooling effect is reduced; at the same time, the impurities brought during cooling will be pelletized together, which affects the quality of the product.
