Description

TECHNICAL FIELD

[0001] The utility model relates to a shavings board production technical field, concretely relates to a shavings board raw material screening device. BACKGROUND

[0002] The shavings board is the broken material made of wood or other lignocellulosic material, and is glued into the artificial board under the action of heat and pressure after applying the adhesive. The raw material for producing the shavings board is often peeled and chipped by the chipper, and a large amount of bark waste is generated during peeling and chipping of the wood. The bark waste often contains a large amount of shavings, which can be recycled as production raw material for producing the shavings board. At the same time, the existing ordinary shavings board is usually a pure wood shavings board, and the raw material required in the production process is generally mainly branch material and wood chips. After a large amount of bark is mixed in these production raw materials, they can only be treated as fuel. Currently, the screening of these raw materials usually uses a vibrating screen, but the screen mesh is easy to be blocked, affecting the screening effect, and cleaning the holes affects the screening efficiency.
