Cutter head fixing device of wood chipper

Abstract

The invention discloses a cutter fixing device of a wood chipper. The cutter head fixing device comprises a cutter head of which the circumferential outer wall is provided with insert grooves distributed uniformly, and the number of the insert grooves is 8~10; a blade support is formed between two insert grooves; and both ends of one side of the blade support are provided with threaded holes in parallel with the circumference of the cutter head, and the interiors of the two threaded holes are in threaded connection with a first blade fastening bolt and a second blade fastening bolt separately. A first motor used for driving the cutter head to rotate is fixed to a connecting block, and the connecting block can move up and down along with a screw rod through a second motor, so that the cutter head can move up and down to adapt to wood to be machined in different thicknesses and sizes, and the efficiency of the wood chipper is improved; each blade of the cutter head is installed with two fastening bolts, with strong pressing force, so that the blades are tightly fit to the cutter head, and the rigidity is improved; the blade loss caused by vibration is reduced, and the cost is low; and the machining effect is good.

Description

technical field [0001] The technology relates to the technical field of cutter head fixing devices, in particular to a cutter head fixing device of a wood chipper. Background technique [0002] Wood chipper is a kind of special equipment for producing wood chips. Wood chipper is also called wood chipper, which belongs to one of the series of wood processing equipment. It is widely used in the material preparation section in the production process of textile, papermaking, pulping, wood-based panel and other industries. The main cutting materials of the wood chipper are peeled small-diameter wood, bamboo, veneer, and leftover wood from felling. The cutting depth of the cutter head of the existing wood chipper is fixed. For the wood material that is too thin or too short and irregular, it cannot be cut evenly. The result is uneven thickness, which affects the effect of the chipper. Moreover, the current cutterhead fixing device generally uses a fastening bolt to install the b...

Problems solved by technology

The cutting depth of the cutter head of the existing wood chipper is fixed. For the wood material that is too thin or too short and irregular, it cannot be cut evenly. The result is uneven thickness, which affects the effect of the chipper. Moreover, the current cutterhead fixing device generally uses a fastening bolt to install the blade. The blade is generally not strong enough to fix and the blade is easy to loosen, resulting in loss of the blade due to vibration. increase the cost
