Abstract

The invention discloses a thermoplastic elastomer extruding and pelletizing device which comprises a motor, a bearing seat, a formwork and an extrusion cylinder which are assembled in the transverse direction; the extrusion cylinder is a horizontal cylinder body, a conveying screw rod for conveying raw materials is arranged in the extrusion cylinder, a discharge hole of the extrusion cylinder is sealed and covered by the formwork, and a plurality of extrusion holes for extruding the raw materials are formed in the formwork; the motor is in transmission connection with a cutter shaft which is transversely and rotatably assembled in the bearing seat, the cutter shaft extends out of the other end of the bearing seat and is fixedly connected with a cutter, and a rotary plane formed by a shearing edge of the cutter along with rotation of the cutter shaft is close to the extrusion outer end face of the formwork and completely covers the area, where all extrusion holes are located, of the formwork; and the formwork and the extrusion cylinder are fixed, the cutter is driven by the cutter shaft and the motor to rotate close to the extrusion outer end face of the formwork, and raw materials continuously extruded from the extrusion holes in the formwork are rotationally cut into particles. The damage frequency of the bearing of the pelletizing mechanism is effectively reduced, and overhaul and maintenance are convenient.

Description

technical field [0001] The invention belongs to granulation equipment, in particular to a thermoplastic elastomer extrusion granulator. Background technique [0002] The dehydration and granulation equipment of existing thermoplastic elastomers (such as SBS, SIS, SEBS, SEPS) is a cantilever type extrusion dehydration and granulation extruder, such as a kind of vertical water ring cutter disclosed in Chinese patent documents with application number 201320473833.0 Granulator, the pelletizing mechanism of this type of extruder is turbine pelletizing, the bearing seat of the pelletizing mechanism is installed vertically, the cutter is a cantilever structure, the gap between the cutter and the raw material extrusion template is 0.15mm, the pelletizing chamber and the bearing A multi-layer oil seal is used for sealing, and the cutter speed is 1500-3000r / min. Due to the vertical structure, it is easy to cause the upper bearing to lack oil, the bearing to be damaged, and the cutter...
