Drum chipper, also known as drum chipper, is a special equipment for the production of wood chips, the equipment is widely used in particleboard factories, medium and high density fiberboard factories, biopower plants, wood chip factories, bamboo processing plants and other industrial production, drum chipper mechanism is advanced, cutting sheet rules, raw material adaptability is wide, easy operation and maintenance. The main raw materials for cutting are logs, wood harvesting and processing residues, furniture factory scraps (such as branches, barks, slats, log cores, etc.), and can also be used to cut non-wood raw materials (such as sugarcane, reeds, moso bamboo, etc.).
The structure of the drum chipper is simple, the drum chipper is mainly forged from steel plates, and the machine is mainly composed of feeding conveying device, upper and lower feeding device, knife stick, feeding device, hydraulic buffer system, electric and so on. The drum chipper drives the rotor to rotate through the main motor, and the bamboo, logs, branches, etc. are cut into flakes and sent to the paper mill through the moving knife and the bed knife.
The unique crushing design of the drum chipper improves the life of the equipment, and the design of the crushing chamber uses multi-stage crushing and fine crushing devices, so that the working efficiency of the equipment is greatly high, the production efficiency is also greatly improved, and the crushed materials are relatively uniform. The design structure of the equipment is reasonable, with few wearing parts, low cost, and also adopts a wear-resistant protection system.
Next, let's introduce the functional characteristics of the drum chipper:
The drum chipper base is welded with high-strength steel plate, which is the supporting foundation of the whole machineTwo flying knives are installed on the knife roller, and the flying knives are fixed on the knife roller by means of specially made flying knife bolts through pressure blocksAccording to the different thickness of the raw material to be cut, the upper feeding roller assembly can float up and down within a certain range with the help of hydraulic systemThe cut qualified sheet falls through the mesh screen hole and is discharged from the bottom, and the large sheet will be cut again in the machine.
Hydraulic system of drum chipper: the oil is supplied to the cylinder by the hand oil pump, which can start the housing, which is convenient for the replacement of the blade, and the upper feeding roller assembly can be lifted during maintenance, which is convenient for adjusting the gap between the flying knife and the bottom knife and the disassembly and assembly of the comb plate.
