Description

Technical Field

[0001] The present invention relates to the field of ring planing machines, in particular to a knife ring and a ring planing machine. Background Art

[0002] A ring flaker is a mechanical device used to prepare wood particles for production. In the production of wood particleboard, a ring flaker is used to make wood particles, which are then made into particleboard. The ring flaker uses a knife ring fixed in the flaker bin to cut the wood to produce particles.

[0003] The knife ring of the ring planer is mainly composed of multiple fixed rings, knife seats and blades. The blades are fixed on the fixed ring in a ring array through the knife seats, so that the blades are set at an inclined angle to the radial direction of the fixed ring. The wood chips are highly rotated by the impeller in the flaking chamber, and the shavings planed by the blades are mainly rod-shaped and flake-shaped. When the proportion of rod-shaped shavings is high, it will lead to low strength of the subsequently manufactured particleboard. It is usually necessary to adjust the angle of the blade on the knife ring to increase the proportion of flake-shaped shavings. Since the knife seat and the blade are mostly fixed to the fixed ring by bolts, when adjusting the blade angle, it is usually necessary to replace the knife seat and the blade. The operation is cumbersome and inconvenient to adjust the blade angle, which affects the quality of particleboard production. After long-term processing, the blade will be damaged. When replacing the blade, it is necessary to first release the bolts fixing the knife seat, and then release the bolts fixing the blade on the knife seat, which is inconvenient to replace the blade.
