Component for avoiding abnormal diameter of plasticized particles for pelletizing of plastic pelletizer

Abstract

The invention relates to the technical field of plastic pelletizers, and discloses an assembly for preventing the abnormal diameter of plasticized particles for pelletizing of a plastic pelletizer, the assembly comprises a retaining mechanism, the center of the interior of the retaining mechanism is rotatably connected with a pelletizing shaft, the outer side of the pelletizing shaft is fixedly connected with a synchronizing mechanism, and the outer side of the synchronizing mechanism is fixedly connected with an external connecting sleeve; and the middle part of the external sleeve is fixedly connected with a bolt mounting block. According to the assembly for avoiding the abnormal diameter of the plasticized particles for pelletizing of the plastic pelletizer, a semicircular head is pushed by a threaded table to move towards the outer side, so that a wire in a hard ball is powered on, an electrorheological body in the hard ball is hardened and expanded, and then the hard ball drives an inclined plug and a driving rod to move towards the outer side; and then the driving rod drives the rubber block to move outwards, so that the rubber block is in contact with the inner wall of the extrusion mechanism, the rotating speed of the granulation shaft is limited, the rotating speed of the granulation shaft is more stable, and the diameter of granulated particles is more uniform.

Description

technical field [0001] The invention relates to the technical field of plastic granulators, in particular to a component for avoiding abnormal diameters of plasticized particles for plastic granulator granulation. Background technique [0002] In the process of plastic molding technology in today's society, more and more plastic manufacturing equipment is designed and manufactured. Therefore, in order to meet the increasing design requirements of plastic manufacturing equipment, plastic granulators are manufactured, and plastic granulators The main machine is an extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. [0003] The main consideration of the extrusion system of a plastic granulator is the screw speed, and the adjustment and stability of the screw speed is the key to the production volume and extrusion speed of the pellets. The screw speed depends on the production volume. The higher the speed, the greater the pro...
