Background

Wood is defined, in its most basic definition, as a material that is processed after felling of trees for use in construction or for the manufacture of articles, and has been the building material of human use since ancient times because of its ready availability and processing. The wood processing industry is the industry which takes wood as raw material and processes the wood by using a mechanical or chemical method to achieve the corresponding purpose.

A large amount of wood chips are generated during the wood cutting process, and the generation of the wood chips interferes with the operation of the operator and adversely affects the health of the operator. Meanwhile, the wood chips have a good economic value, and thus the wood chips generated in the wood processing process need to be recycled. Current saw-dust recovery unit mainly carries out the box that preliminary treatment was carried out to the saw-dust and the saw-dust including retrieving the cover and carries out the packing forming device that compresses. It mainly has the following disadvantages:

1. the recovery cover is mostly arranged on one side of the cutting blade and is not completely matched with the wood chip splashing direction, so that the wood chips are not completely collected;

2. the feeding device is absent in the box body for primarily treating the sawdust, so that the sawdust entering the box body under the action of the negative pressure fan cannot be rapidly discharged, and is easy to accumulate at a feeding port, and the collecting effect of the negative pressure fan on the sawdust is influenced;

3. the crushing device for the sawdust is lacked, the size difference of the sawdust generated during cutting is large, the sawdust is simply screened by the screening device, more sawdust which does not meet the requirement of the particle size is obtained, special equipment is still needed for secondary processing of the sawdust which does not meet the requirement of the particle size, the equipment investment is increased, and the improvement of the production efficiency is restricted;

4. sawdust which does not meet the requirement of the particle size on the screening device needs to be discharged manually, so that the labor cost is increased, and the production efficiency is prevented from being improved;

5. when the sawdust is fed into the packaging and forming device, the blanking position of the sawdust is fixed, and the sawdust is pressed differently during press forming;

6. the packing and forming device drives the push plate to move for a certain distance through the hydraulic cylinder to press and form the sawdust, and the extending distance of the piston rod of the hydraulic cylinder cannot be controlled according to the actual sawdust pressing condition;

7. lack the processing apparatus who produces the flue gas when cutting to timber, the flue gas directly discharges, endangers operating personnel's safety.
