Problems solved by technology

In the prior art, the screening of plastic particles is completed by installing a vibrating screen naturally driven by the outer wall of the system motor on the lower side of the discharge port of the granulator. The exit is close, and the temperature of the material particles is high, so that the material particles are oxidized and discolored due to untimely cooling, which affects the product quality; secondly, dust and material particles are easy to block the sieve hole, the production efficiency is low, and the screening effect is poor

Abstract

The invention discloses a material particle screening device for a plastic extrusion granulation system. The material particle screening device comprises a rack, a motor, a sieve, a material bin and damping springs, wherein the sieve is fixedly arranged on the upper side of the material bin, a vibrator is installed between the rack and the sieve, at least two damping springs are installed at the bottom of the material bin, and an air blowing device is installed on the rack on the upper side of the sieve. According to the material particle screening device, the temperature of plastic particles can be reduced, oxidation stain or mutual bonding is avoided, meanwhile, the dust flowing is accelerated, sieve holes are prevented from being blocked, the screening efficiency and the production efficiency are improved while the quality of material particles is ensured.

Description

technical field [0001] The invention relates to the technical field of plastic machinery manufacturing, and relates to a downstream processing device for plastic extrusion equipment, in particular to a particle screening device for a plastic extrusion granulation system. Background technique [0002] At present, the main production method of plastic materials is to produce granular raw materials on the extrusion granulation unit. The equipment of the extrusion granulation production line mainly consists of an extruder, a cooling water tank, a drying fan, a traction mechanism, a pelletizer and a particle screening device. After the plastic extruded strips are cooled, dried and chopped, the subsequent process is to screen the output materials of the granulator to remove the powder produced during the granulation process and the oversized or undersized For unqualified particles, keep the particles with qualified size and enter the next process. In the prior art, the screening ...
