Drum chipper for wood processing

Abstract

The invention relates to the technical field of wood processing, and discloses a drum chipper for wood processing. The drum chipper comprises a transmission rod, a knife roll, a knife rest, a rotatingrod, a knife and a rotating disc. The transmission rod is fixedly connected with the center of the knife roll in a sleeving mode, six uniformly distributed arc-shaped grooves are formed in the outerring of the knife roll, a through angle groove is formed in the inner side of the knife roll, a butt joint groove is formed in one side of the angle groove, the bottom of the knife rest is fixedly connected with the rotating rod, one end of the rotating rod is fixedly connected with the rotating disc, and a positioning hole is formed in the end, close to the rotating disc, of the knife rest. By arranging the knife rest and the rotating rod, the angle of the knife rest can be adjusted under the driving of the rotating rod, so that the angle of the knife on the knife rest is adjusted, and the thickness of a cut wood chip can be controlled; and the rotating rod can only drive the knife rest to perform circular motion by arranging the angle groove, and the possibility that the knife rest is separated from the knife roll is avoided.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a drum chipper for wood processing. Background technique [0002] Drum chipper is a traditional machine used to prepare high-quality wood chips. It can cut logs and small-diameter wood into high-quality industrial wood chips with uniform length and thickness. It can also be used to cut various wooden materials such as boards. [0003] The thickness of the cut wood chips is affected by the angle or length of the cutter. In the existing drum cutting machine, the cutter fixed on the cutter roller has been fixed in position and angle since leaving the factory. If you want to adjust it, you need to move the cutter The roller and cutter are disassembled for substantial rectification, which is not suitable for industrial production. At the same time, the installation of the cutter is very troublesome. Most of them use flying cutter bolts and flying cutter pressure blocks to fix ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing drum-type chipper proposed in the background technology, the present invention provides a drum-type chipper for wood processing, which is equipped with adjustable cutter angle, adjustable wood chip thickness and disassembly and maintenance. The advantages of convenience, solve the technical problems raised in the above-mentioned background technology
