Composite particle board production and manufacturing process

Abstract

The invention provides a composite particle board production and manufacturing process which uses a composite particle board production and manufacturing device. The composite particle board production and manufacturing device comprises fixed rods, a top plate, a vibration screening mechanism, a wood chip screening mechanism and limiting mechanisms. According to the vibration screening mechanism,wood chips and broken stones can be separated, the design that gravel falling openings are matched with auxiliary blocks enables the broken stones near the gravel falling openings to fall into the gravel falling openings easily, and meanwhile, the design of rotating rollers can prevent the broken stones from falling back into the wood chips under the action of gravity in the wood chip recycling process; and in addition, the limiting mechanisms and a second motor are matched for use, so that screened wood chips can be recycled, and the problems are solved that in the prior art, a wood chip screening device is simple in structure, only can play a screening role, cannot recycle the screened wood chips and often needs to recycle the wood chips manually, resulting in lower wood chip recycling efficiency and lower particle board production efficiency.

Description

technical field [0001] The invention relates to the technical field of particle board production, in particular to a manufacturing process for a composite particle board. Background technique [0002] Particle board is a wood-based board made of wood or wooden poles and logs, fine and dense wood fibers are used on both sides, long wood fibers are sandwiched in the middle, and adhesives are applied and then glued under heat and pressure. The board is made of wood chips (sawdust). The wood fiber particles in the board are relatively large, which retains more of the essence of natural wood. It is a new type of environmentally friendly substrate. The surface of the particle board is smooth and delicate, and there will be no There are defects such as knots and insect eyes, and the stability is good, and the material is uniform; [0003] In the production process of the existing particle board, the sawdust needs to be dried first, then the dried sawdust is sieved, then the sifted...

AI Technical Summary

Problems solved by technology

[0003] In the production process of the existing particle board, the sawdust needs to be dried first, then the dried sawdust is sieved, then the sifted sawdust is mixed with glue, and finally the mixed sawdust is pressed into shape. Among them, the sieving of wood chips is mainly to remove the gravel in the wood chips. The structure of the device for sieving wood chips in the prior art is simple, and it can only play the role of sieving, and cannot perform screening on the sieved wood chips. Recycling often requires manual recycling of wood chips, which leads to the recovery efficiency of wood chips, thereby reducing the production efficiency of particle boards; in addition, the screening device in the prior art does not completely separate wood chips and gravel, resulting in the recycling of wood chips. During the process, gravel will be mixed into the sawdust, which will affect the quality of the sawdust
