The working principle and composition of the drum chipper

Working principle. When using a drum chipper, the wood is first fed from the feeding port. When the wood comes into contact with the cutting blade, it will be cut with the high-speed rotation of the cutting blade. The cutting mechanism is a rotating drum. Install several flying knives, and when the flying knives rotate, the wood is processed into wood chips. There is a plurality of square through holes on the outer edge of the drum wheel, and the cut qualified pieces fall through the mesh screen holes and are discharged at the bottom, and the large pieces will be cut again in the machine.

The main purpose of a drum chipper. The chipper can cut logs, branches, veneers, waste veneers, bamboo, cotton stalks, and other non-wood fiber stem into pieces of a certain size, which can be used as the basic ingredients of the particleboard, fiberboard, non-wood wood-based panels, and pulp and paper.
The drum chipper has an advanced structure, high quality of cutting chips, wide adaptability of raw materials, and convenient operation and maintenance. The machine consists of a machine base, knife roller, upper and lower feeding rollers, conveyor belt, hydraulic system, and other parts.
The machine base of the drum chipper is welded with a high-cavity steel plate, which is the support base of the whole machine; two flying knives are installed on the knife roll, and the flying knives are fixed on the knife roll with a specially manufactured flying knife bolts through the pressure block. ; According to the different thicknesses of the raw materials to be cut, the upper feeding roller assembly can float up and down within a certain range with the help of the hydraulic system; the cut qualified flakes fall through the mesh screen holes, and there is a bottom row, and the large flakes will be in the machine. Re-cut inside.
The hydraulic system of the drum chipper: The hand oil pump supplies oil to the oil cylinder, and the cover can be activated to facilitate the replacement of the blade. During maintenance, the upper feeding roller assembly can be lifted to adjust the gap between the flying knife and the bottom knife, and the comb plate.
Through the above introduction and analysis of the working principle and composition of the drum chipper, hope it helps you.
