Drum chipper is a traditional product, which has been widely used by domestic and foreign merchants for many years due to its superior performance, high quality and high cost performance. Drum chipper is a special equipment for preparing high-quality wood chips. It is applicable to paper mills, particle board mills, fiberboard mills, wood chip production bases and wood chip export bases. It can cut high-quality industrial wood chips with uniform growth, smooth cut and uniform thickness, as well as branches and plates.

Product introduction:

Drum chipper is a special equipment for preparing various high-quality wood chips, which is used in the wood chip production and export bases of paper mills, particle board mills, and fiberboard mills. It can cut high-quality industrial wood chips with uniform growth, smooth cut and uniform thickness, such as logs and small diameter wood, and can also cut branches, plates, etc.

Working principle:

The wood is fed from the feeding port. When the wood touches the cutting blade, it is cut along with the high-speed rotation of the cutting cutter head. The cutting mechanism is a rotating drum, on which several flying knives are installed. When the flying knife rotates, the wood is processed into wood chips. There are a number of square through holes on the outer edge of the drum. The cut qualified sheets fall through the mesh screen hole and are discharged from the bottom. Large sheets will be cut again in the machine.

Structural composition:

Drum chipper is composed of machine body, knife roll, upper and lower feeding mechanism, hydraulic system, feeding device, etc.

1. Machine body: welded with high-strength steel plate, which is the support foundation of the whole machine.

2. Knife roll: Two or three or four flying knives are installed on the knife stick, and the specially manufactured flying knife bolts are used to fix the flying knife on the knife roll through the pressure block.

3. Hydraulic system: supplied to the oil cylinder by the oil pump, the cover can be started to facilitate the replacement of the blade; During maintenance, the upper feeding roller assembly can be lifted to facilitate the adjustment of the clearance between the flying knife and the bottom knife and the disassembly and assembly of the comb plate.

4. Upper and lower feeding mechanism: It is composed of feeding interface, upper and lower feeding rollers and feeding gap adjustment mechanism. The wood entering from the feeding interface is pressed by the upper and lower feeding rollers, and feeds to the cutting mechanism at a certain speed to control the size of wood chips to be cut; When processing thick wood, it is adjusted by the feeding gap adjusting mechanism.

Main purpose:

The chipper can cut logs, branches, veneers, waste veneers, bamboos, cotton stalks and other non wood fiber stems into pieces of certain specifications, which can be used as the basic raw materials for at least chipboard, fiberboard, non wood wood-based panels and pulp and paper making. The machine has advanced structure, high quality of cutting pieces, wide adaptability of raw materials, and convenient operation and maintenance. The machine is composed of machine base, knife roll, upper and lower feeding rolls, conveyor belt, hydraulic system and other parts. The base is welded with high cavity steel plate, which is the supporting foundation of the whole machine; Two flying knives are installed on the knife roll, and the specially manufactured flying knife bolts are used to fix the flying knife on the knife roll through the pressure block; According to the different thickness of the material to be cut, the upper feeding roller assembly can float up and down in a certain range with the help of the hydraulic system; The cut qualified sheets fall through the mesh screen hole, with a bottom row, and the large sheets will be cut in the machine.

Hydraulic system: the oil is supplied to the oil cylinder by the hand oil pump, and the cover can be started to facilitate the replacement of the blade. During maintenance, the upper feeding roller assembly can be lifted to facilitate the adjustment of the clearance between the flying knife and the bottom knife and the disassembly and assembly of the comb.
