The manufacturing process can apply adhesive and (or) additives. Fiberboard has the advantages of uniform material, small difference in longitudinal and transverse strength, and is not easy to crack, and is widely used. About 2.5~3 cubic meters of wood is needed to manufacture 1 cubic meter of fiberboard, which can replace 3 cubic meters of sawn timber or 5 cubic meters of logs. Developing fiberboard production is an effective way to utilize wood resources comprehensively.

[0004] When making fiberboard, wood fibers need to be stripped into fine fibers and then laid. The fiber is layered to form the forming state of the plate blank.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The first licker-in rollers 52 and the second licker-in rollers 53 rotate in the same direction, and the rotating speed of the first licker-in rollers 52 is greater than that of the second licker-in rollers 53.

[0031] When the wood fibers are placed above the fiber paving assembly 5, the first licker-in rollers 52 and the second licker-in rollers 53 rotate, and the sharp spikes on the surfaces of the first licker-in rollers 52 and the second licker-in rollers 53 are used to peel off the wood fibers. The peeled wood fibers fall from the gap between the first licker-in rollers 52 and the second licker-in rollers 53 to the belt conveyor 2, and a board blank is formed on the belt conveyor 2. Then, the belt conveyor 2 transfers the board blank to a hot press for hot pressing and forming. Thus, the forming of the board blank is realized, the efficiency is greatly improved compared with the traditional board blank paving, the wood fibers are evenly paved, and the thickness of the hot-pressed board is uniform.

[0032] In the embodiment, the two ends of each first licker-in roller 52 are connected to the side mounting plate 51 through bearings, and a first pulley 54 is arranged at the outer end of one end of each first licker-in roller 52. A plurality of first pulleys 54 are connected through a first belt 55. Any one of the plurality of first licker-in rollers 52 is further connected to a second transmission assembly 56.

[0034] Through the above technical scheme, the first licker-in rollers 52 and the second licker-in rollers 53 are separately driven by the second transmission assembly 56 and the third transmission assembly 59, so that the first licker-in rollers 52 and the second licker-in rollers 53 have a speed difference. The speed difference can better peel and pave the wood fibers, and the paving efficiency of the board blank is improved.

[0035] In the embodiment, the two sides of the fiber paving assembly 5 are fixedly connected to the two sides of the belt conveyor 2 through a plurality of supporting beams 4.

[0041] When the board blank is laid, a certain dust or flying fluff is generated; the dust of the outer shell 7 can be cleaned under the extraction of the negative pressure pipe 10, so that the dust raising is avoided.

[0042] As a further description of the utility model, the first transmission assembly, the second transmission assembly and the third transmission assembly are all composed of a motor and a speed reducer.

[0043] The working principle of the utility model is as follows: when in use, the wood fibers are placed above the fiber laying assembly 5, the first spike roller 52 and the second spike roller 53 rotate, the wood fibers are stripped by the spikes on the surfaces of the first spike roller 52 and the second spike roller 53, the stripped wood fibers fall from the gap between the first spike roller 52 and the second spike roller 53 to the belt conveyor 2, and the board blank is formed on the belt conveyor 2, and then the belt conveyor 2 transmits the board blank to the hot press for hot pressing and forming; so that the forming of the board blank is realized, the efficiency is greatly improved compared with the traditional board blank laying, the laying of the wood fibers is more uniform, and the thickness of the hot-pressed plate is uniform;
