In the medium density fiberboard and particleboard production line. The drum chipper is the main equipment in the preparation section. The structure of the drum chipper is simple and compact. The flying knife is easy to load and unload, and its requirements for raw materials are not high!
It is especially suitable for the board edge and the single board small diameter wood and Raw materials such as twigs and coffins are cut into wood chips. Therefore, drum chippers have been widely used in MDF production and particleboard production. However, after a period of use of the chipper, the flying knife seat on the knife roll will Wear occurs. The longer the cutting time, the more serious the wear.
The consequent consequences are: 1. The yield of wood chips is reduced! The production cost is increased by 2. The reliability of the flying knife clamping is reduced, and the flying knife accident is easily generated. In order to avoid the above situation, it is necessary to repair the knife roll in time to restore it to the original design state but for the user!
Repairing the knife roll is very difficult. First, because the knife roll must be repaired by the equipment manufacturer to achieve the original The design index; the second is because the shutdown is stopped, which affects the economic benefits.
Considering the above reasons! We have made some improvements to the material and structure of the knife roll when designing the knife roll! This avoids the stop repairing the knife due to the wear of the flying knife seat. Roll loss For the improvement of the structure of the knife roll, we have designed two solutions! And they have been verified in practice.
