Apparatus for producing wood-wool and equipment thereof

Abstract

The invention discloses a device for preparing wood wools and equipment thereof; the device includes a feed device, a discharge device and a breaking device arranged between the feed device and the discharge device; the breaking device is driven by a motor; the invention is characterized in that the breaking device is provided with breaking rollers that are arranged in pairs; the breaking rollersare arranged in that crushed aggregates of a single board are fed between the breaking rollers along the fiber direction and are sheared into the wood wools when passing through the breaking rollers;the equipment or device of the invention shears the crushed aggregates of the single board into the wood wools by shearing action by the breaking rollers with cylinderknives in pairs, which not only effectively utilizes high grade logs with good quality and greatly reduces the cost of wood wool plates, but also improves the property of the wood wool plates. The property of the wood wool plates manufactured by the wood wools produced by the invention can meet the requirement of 'Standard for a Flakeboard with an Oriented Structure LY / T1580-2000'.

Description

technical field [0001] The invention relates to a device and equipment for preparing wood wool, in particular to a device and equipment for preparing wood wool from veneer processing waste. Background technique [0002] At present, in the process of veneer processing in my country, the veneer processing factories in China usually select high-grade logs with better material than processing materials, and the best part of the log is the sapwood part, and the logs that can be processed into veneers are rotary cut. 30% of the sapwood shredded veneer processed from gardening or planing and returning to the square, that is to say, nearly 30% of the log sapwood with good quality has become waste and has not been well utilized. These wastes are mainly used The boiler fuel in the factory was burned as cheap fuel, which caused a huge waste of high-grade logs with good materials. [0003] On the other hand, the existing wood wool board has the problem of poor performance of the board du...

Problems solved by technology

[0002] At present, in the process of veneer processing in my country, veneer processing factories in China usually select high-grade logs with better material than processing materials, and the best part of the log is the sapwood part, which can be processed into veneer by rotary cutting. 30% of the sapwood shredded veneers processed in the garden or sliced ​​back to the square, that is to say, nearly 30% of the log sapwood with good quality has become waste and has not been well utilized. These wastes are mainly used The boiler fuel used in the factory was burned as cheap fuel, which caused a huge waste of high-grade logs with good materials

[0003] On the other hand, the existing wood wool board has the problem of poor board performance due to the poor quality of the raw material wood wool used

Wood wool, the raw material of existing wood wool boards, is usually sliced ​​from wood. Because the length of the wood segment is relatively short, the length of the wood wool obtained by sliced ​​is also relatively short, mostly 50 cm; wood wool is produced by sliced , the direction of the knife and the direction of the wood fiber form a certain angle, the wood fiber obtained by planing is damaged by inward bending, and the long wood fiber is naturally twisted, and the rigidity of the wood fiber is insufficient. The finished board, the wood wool presents a criss-cross and disorderly network structure, with many unpenetrated mesh holes, which cannot form a frame structure microscopically, resulting in poor strength of the wood wool board.
