Wood-plastic granulating production line

Abstract

The invention provides a wood-plastic granulating production line. The wood-plastic granulating production line comprises a machine frame, a screw feeding device, a screw extruding device, a granulation mold and a granulator, wherein the screw feeding device, the screw extruding device, the granulation mold and the granulator are fixed on the machine frame and are arranged sequentially along the granulating direction. The wood-plastic granulating production line is characterized by further comprising a blowing pipe which is connected with a granular material outlet of the granulator through a three-way pipe, wherein the other end of the blowing pipe is connected to a funnel-shaped-structure finished product bin, a ventilating barrel which communicates with the interior of the finished product bin is arranged at the top of the finished product bin, and a dust removal device connected with the ventilating barrel is arranged. According to the wood-plastic granulating production line, dust adhered to particles can be blown off by an online dust removal system so as to achieve dust-particle separation, and the dust is subjected to online treatment and then is subjected to harmless emission; the optimally-designed screw feeding device and extruding device can be used for increasing the production efficiency of granulating; and equipped upper and lower limit material level gages can be used for automatically monitoring a level of materials in the finished product bin and meanwhile providing real-time and accurate information for production and bagging in a manner of being matched with a controller and an alarm, so that the efficiency and quality of production are further improved.

Description

technical field [0001] The invention belongs to the technical field of industrial granulation production, and in particular relates to a wood molding granulation production line. Background technique [0002] The wood-plastic production line is used to produce extruded wood-plastic particles. The whole production line is based on the melt extrusion process to mix wood powder and plastic powder, then melt and extrude them to form large-size particles, and then cut the large-size particles through the cutting process. The finished wood-plastic particles can be used to process and produce boards instead of wood and plastic. The wood-plastic production line is mainly composed of a raw material feeding device, a granulator, a pelletizing device and an output device for finished particles. The raw material feeding device feeds the mixed powder of wood powder and plastic powder into the granulator, and the granulator is based on melt extrusion The pressing process extrudes the mix...
