Wood peeling is an indispensable process in wood production and timber department. In many projects, it is necessary to peel the logs before processing. The wood peeling machine makes use of the unique force generated by the rotor with peeling teeth to make the wood segment move circularly in the bin trough plate, and also makes rotary movement and irregular jumping around the axis of the wood segment itself. So far, the bark has been rapidly separated by constant friction, impact and extrusion between wood segments and teeth, wood segments and wood segments, and wood segments and bins to achieve efficient peeling effect.

Development trend

1. The drum mechanical peeling machine appeared first in mechanical peeling, and has a history of more than 60 years. It has shown its strong vitality in long-term production practice. The drum peeling machine can peel curved wood, even logs or branches with forks, and can remove decay, which are far superior to other mechanical peeling machines. The wet drum peeling machine has less wood damage than the dry drum peeling machine, but the dry drum peeling machine has high production efficiency and no pollution and public hazards. Therefore, the two types of drum peeling machines will continue to be used and developed in the future.

At present, the drum peeling machine is developing towards large specifications to further improve production efficiency and reduce costs. For example, the roller peeling machine with a diameter of 5 meters, a length of 21 meters and a production efficiency of 200 m3/h has been used in Northern Europe. A long log drum peeling machine with a diameter of 3.8 meters, a length of 60 meters, and a production efficiency of 300 cubic meters per hour is also used. This machine can peel logs with a length of 7 meters;

2. Ring-type peeling machine is a good type of mechanical peeling machine, which has been widely used and is constantly developing. These peeling machines adopt some new technologies, and the automation degree of single machine is getting higher and higher.

At present, the ring-type peeling machine is developing in the direction of expanding its scope of application. A lot of ring-type peeling machines and special peeling machines with new structures have been developed. Some have a rounding structure, which can improve the peeling quality and expand the scope of use; Some trees can peel bark with high longitudinal fiber strength and oil; It has also developed a knot stripping machine;

3. The production efficiency of the milling cutter type peeling machine is lower than that of the ring type and the drum type peeling machine, and the wood loss is also greater than them. However, due to its simple structure and low cost, it is still widely used in the peeling of small and medium-sized batches of logs;

4. The hydraulic peeling machine is an advanced peeling method. It is not limited by the shape of logs. It has high peeling purity, high speed, and no wood loss. It has been put into production in a large number in some countries, and will have further development in the future;

5. Some countries are experimenting with pneumatic peeling, peeling of wood chips and peeling of chips at the same time. At the same time, new peeling methods such as ultra-high frequency peeling method, electric water wave peeling method, magnetic field effect and so on continue to emerge, opening up a broad prospect for the peeling industry. The above is the basic knowledge of wood peeling machine introduced by Xiao Bian. Through the article, I hope you can know more about wood peeling machine. ​​​​

1. The open silo can be used to feed from one end and discharge from the other end of the pipelined operation, which overcomes the shortcomings of the existing drum peeling machine's power failure to feed and discharge, and the segmented working mode, and has high working efficiency;

2. Because of the impact of the tooth on the wood segment, the wood segment not only circulates in the casing, but also rotates around itself, so the peeling efficiency is high. It also has a good stripping rate for frozen wood, dry wood and tree species that are difficult to peel;

3. It has strong adaptability to wood, and can peel wood segments of different species, diameters, lengths and shapes. Because the wood segments do rotary motion and irregular jumping, the concave part of the curved wood segments can also be in good contact with the peeling teeth. Therefore, the stripping rate of bent logs is much higher than that of other roller types;

4. Because the huge shell is fixed, it has low energy consumption, low failure rate, small maintenance workload, much lower vibration and noise than the drum peeling machine. The machine can be produced on the ground, even without base installation, and is convenient to use.
