Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wood processing, and in particular to a wood chipper for wood processing. BACKGROUND

[0002] Wood chipper, as a key equipment in the field of wood processing, is defined as cutting logs or large pieces of wood into a certain specification of wood chips through a specific mechanical way. These wood chips are widely used in the production of raw materials in the textile, papermaking, pulping and wood-based panel industries, and are important tools for improving raw material utilization efficiency and promoting wood recycling. However, during a long period of operation, the blades on the chipper core component, the chipper knife roll, often face severe challenges.

[0003] Specifically, due to the hardness, fiber structure of wood and friction and impact during cutting, the blades on the knife roll will gradually show signs of wear. This wear not only leads to a significant decrease in the cutting performance of the blades, such as a decrease in cutting efficiency and an increase in cutting surface roughness, but also directly affects the quality of the chips, such as uneven wood chip size and irregular shape. More seriously, as the wear intensifies, the blades may not be able to maintain an effective cutting angle and strength, thus failing to complete the intended chipper task, and even breaking, posing a threat to production safety.

[0015] The beneficial effects achieved by the above structure are as follows:

[0016] (1) In order to solve the problem that due to the hardness, fiber structure of wood and friction and impact in the cutting process, the blades on the knife roller will gradually appear wear phenomenon, which not only leads to the cutting performance of the blade to decrease significantly, but also directly affects the quality of the chip, the present application provides a wood fiber embrittlement type chip mechanism, high temperature steam is used for heating wood, which can soften the fibers inside the wood, and the wood becomes more plastic. This treatment can also increase the water content in the wood, making it easier to form ice crystals in the subsequent freezing process. The softened wood fibers will reduce the cutting resistance when cutting, and the ice crystals formed by the increased water during freezing can further improve the cutting effect.

[0017] (2) Through the wood fiber brittle type chip mechanism, the liquid nitrogen is atomized by the ultrasonic atomizer and sprayed to the wood, which rapidly cools the surface and interior of the wood. The rapid freezing causes the water in the wood to freeze rapidly, resulting in an expansion effect and the formation of micro-cracks and stress concentration points in the interior of the wood. This rapid freezing treatment makes the wood brittle, making it easier to cut during chip processing, which helps to reduce the resistance of mechanical chip processing and improve processing efficiency.

[0018] (3) Through the wood fiber brittle type chip mechanism, after steam heating and rapid freezing with liquid nitrogen, the wood exhibits low cutting resistance during chip processing, and the chip knife roller can more easily cut, thereby reducing blade wear and extending tool life. The processed wood chips are smoother and have higher cutting surface quality, reducing uneven texture and surface roughness.

[0019] (4) Through the wood fiber brittle type chip mechanism, the atomized freezing of liquid nitrogen causes the water in the interior of the wood to freeze rapidly, resulting in a loss of flexibility in the wood in a short period of time, making it brittle. Freezing forms micro-cracks or expansion stress points in the interior of the wood, making it easier to break during chip processing.

[0020] (5) Through the wood fiber brittle type chip mechanism, the fibers are first softened and then rapidly frozen, resulting in a significant decrease in the flexibility and elasticity of the wood, making it more fragile. During chip processing, the wood resistance faced by the chip knife roller is smaller because the freezing makes the wood more easily separated under the action of the blade, reducing the rebound force and friction of the wood during chip processing, making the cutting process smoother while reducing blade wear and heat generation.

[0021] (6) Through the wear-reducing chip auxiliary mechanism, the atomized lubricating oil can form a lubricating film between the knife roller and the wood, effectively reducing the friction coefficient between the two, thereby reducing direct contact and wear between the knife roller and the wood.

[0022] (7) Through the wear-reducing chip auxiliary mechanism, the atomized lubricating oil ensures smooth and unobstructed cutting of the knife roller, reducing the resistance and heat generated by friction, making the chip processing process more efficient.

[0023] (8) Through the wear-reducing chip auxiliary mechanism, the heat generated during cutting may cause thermal damage to the wood, affecting its quality and subsequent processing performance. Atomized lubricating oil can effectively reduce the cutting temperature and reduce the risk of thermal damage. BRIEF DESCRIPTION OF DRAWINGS
