Granulating device for producing flame-retardant plastic-wood composite material

Abstract

The invention discloses a granulating device for producing a flame-retardant plastic-wood composite material, and relates to the technical field of material processing equipment. The granulating device comprises a shell, wherein a feeding hopper is arranged at the upper end of the shell, a mounting cavity is formed in the lower end of the shell, and an material extruding cylinder is connected in the mounting cavity; and the material extruding cylinder comprises a cylinder head, a cylinder body and an material extruding head which are connected in sequence, a heat preservation installation base is arranged outside the material extruding cylinder, and the heat preservation installation base is fixedly connected with a conveying mechanism. According to the granulating device, a material mixing bin, a material conveying channel, the material extruding cylinder, a material cutting mechanism and the conveying mechanism are arranged, the material is fully heated and mixed through the material mixing bin, and the material is continuously supplied to the material extruding cylinder through a material pushing piston of the conveying channel for cutting and granulation, the material cutting mechanism is used for cutting, and finally, flue gas and heat are removed through the material conveying mechanism, and the flue gas and the heat are conveyed out, so that the granulation operation is completed, the structure is simple, the problems that the quality of an existing granulating device is low and the corresponding process is environment-friendly are solved, and the granulating device is suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of material processing equipment, in particular to a granulation device for the production of flame-retardant plastic-wood composite materials. Background technique [0002] Flame-retardant wood-plastic composite material is a composite material made of wood, plastic and high-content flame-retardant auxiliary materials. Due to the good environmental performance and quality improvement of flame-retardant wood-plastic composite materials, people's acceptance is gradually increasing, and the output increase yearly. Mixing and granulation is the first process in the processing of flame-retardant wood-plastic composite materials, and it is also a key step that directly affects the quality of wood-plastic composite materials. [0003] After years of development, the existing granulation equipment still stays at the initial primitive stage, which is not conducive to improving the quality of wood-plastic composite ...
