Twin-screw extruder die head for plastic particle production

Abstract

The invention relates to a twin-screw extruder die head for plastic particle production. The extruder head comprises a die head body capable of being fixedly connected with the twin-screw extruder head, a positioning guide groove, a groove-type flow channel, die holes and forming strip-shaped plastic supporting plates. The middle of the inner side of the die head body is provided with the positioning guide groove connected with the extruder head in the radial direction. The middle of the bottom of the positioning guide groove is provided with the groove-type flow channel for balancing the die head pressure. A plurality of rows of the die holes are formed in the groove-type flow channel in the vertical direction side by side in parallel. Each forming strip-shaped plastic supporting plate is outwards arranged at the position, below each row of die holes, on the die head body in the radial direction, and a plurality of forming strip-shaped plastic output grooves are formed in the forming strip-shaped plastic supporting plates corresponding to the die holes of each row of die holes. The twin-screw extruder die head is scientific in design, convenient to use and simple in structure, the extrusion efficiency of an extruder is improved, manpower and material resources are saved, and quality of finished products of plastic particles is guaranteed and improved.

Description

technical field [0001] The invention belongs to the technical field of plastic granule production and processing equipment, in particular to a twin-screw extruder die head for plastic granule production. Background technique [0002] The twin-screw extruder for plastic granules is mainly used for the melt blending and modification processing of one or several kinds of plastic granules. The twin-screws rotate in the same direction or in the opposite direction to realize the heating and melting of the plastic granules and promote the various processes between the melts. The chain reaction is fully carried out in the process of melt flow, and at the same time, the melt processing and molding of plastics are realized. The twin-screw extruder currently used in industry includes a screw body, a filter plate, a power motor, a machine head, an oil pump, a twin-screw, and a die head for extrusion. In the production process, the materials are pre-mixed and then extruded through a twi...

AI Technical Summary

Problems solved by technology

[0003] Most of the die holes in the head of the current twin-screw extruder are designed in one row. Due to the limited width of the head, if the die holes are only designed in one row, this will greatly reduce the extrusion efficiency of the twin-screw extruder. At the same time, it also wastes a lot of manpower and material resources, which increases the production cost of the enterprise.
