Abstract

The invention discloses a sawdust compressing device. The sawdust compressing device comprises a machine body frame, a drive device and extruding devices, wherein the drive device and the extruding devices are arranged in the machine body frame. The drive device comprises a mounting base, a drive motor, a gear set, eccentric wheels, a linkage bearing and spring parts. A rotary shaft is verticallyarranged on each side face of the circumference of the mounting base, the eccentric wheels and the gear set are coaxially fixed to the rotary shafts, and an output shaft of the drive motor is fixedlyconnected with one rotary shaft. In the using process, the drive motor drives the rotary shafts to rotate, the rotary shafts drive extruding screws to rotate to extrude compressed sawdust, extruding force and friction heat are continuously generated in the compression process, lignin in the sawdust has the effect of a binder, sawdust rods are formed in extruding barrels, through the transmission effect of the gear set, the other rotary shafts are driven to rotate to drive the extruding devices to extrude the sawdust, multi-station synchronous operation is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to extrusion compression molding, in particular to a sawdust compression device. Background technique [0002] Sawdust refers to the sawdust and shaving powder left over from wood processing. The amount of wood residues in the national forestry industry is about 40 million cubic meters, and most of these residues are reduced to wastes and become environmental burdens. [0003] Due to its loose structure, large land occupation, and high storage and transportation costs, the wood residues greatly reduce their value and are eventually discarded. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention is to provide a sawdust compression device. The sawdust itself is a crude fiber raw material, and the rich lignin has strong viscosity. The sawdust compression device preliminarily compresses the sawdust through multi-stage extrusion . [0005] In order to achieve the above object, the p...
