[0002] Wood chipper is a special equipment for producing wood chips. Wood chipper is also called wood slicer, which belongs to one of the wood processing equipment series. It is widely used in the material preparation section of the production process of textile, papermaking, pulping, wood-based panels and other industries. The main cutting materials of this machine are small-diameter wood, bamboo, board skin material and leftovers of felled firewood after peeling. However, it does not have the function of uniform cutting for over-thick (above 350mm), over-thin (below 30mm), over-short (below 250mm), over-thin (below 5mm) and irregular raw materials (undecomposed stumps, branches, etc.), or just cuts the raw materials on the original basis. It does not have the function of layered cutting for slices of bamboo with a wall thickness of less than 5mm. It is a forestry machinery that cuts the residues in forest felling and wood processing into craft wood chips. Wood chips are mostly used as raw materials for pulp, hydrolysis and wood-based panels. Disc chippers play a key role in the field of wood processing. Because the wood chips they cut are of uniform size and thickness, and the qualified rate of wood chips is high, they are widely used in paper mills, wood-based panel factories, wood chip production bases, etc. During use, the cutters on the disc chippers need to be replaced and sharpened regularly to ensure the production efficiency and quality of the disc chippers.
