(54) LINE FOR MANUFACTURING SHEET MATERIALS FROM PLANT FIBERS (57) The invention relates to the woodworking industry. The purpose of the invention is to improve the quality of sheet materials and the expansion of the range. The line contains a fiber separation unit (ASU) 13, which is made in the form of a tank divided by partitions with adjustable gates into separate compartments for the fiber of the corresponding layer, each of which is connected by a branch pipe with a corresponding dryer 3. The dispensing unit 2 storage unit 1 is filled to a S

which is supplied to the ASU 13. The fiber enters the dryer 3 by means of an air stream, where chemical additives are introduced into the fiber and are fed into the forming heads 7 5 which form a multi-layer carpet 8. The carpet 8 enters the cold pre-press 9, and then into the hot Press 11. 4 Il.

The invention relates to lines for the production of fiber boards, including from spun fibers of textile production, and can be used in the timber and woodworking industry for the manufacture of wood fiber boards in a dry manner.

The purpose of the invention is to increase the quality of sheet materials and expand their range.

FIG. 1 shows the production line of sheet materials, a general view; in fig. 2 shows a section A-A in FIG. in fig. 3 shows a section BB in FIG. one; in fig. 4 — node I in FIG. one.

The sheet material production line contains a fiber storage unit 1 with a feed dosing angle 2, dryers 3, equipment 4 for preparing chemical additives and mixing them with fiber 5 forming a machine 6 with forming heads 7 for producing a multilayer carpet 8, cold pressing press 9 , knot 10 of the preliminary trimming of the carpet, hot process 11, format-trimming machines 12.

The line is also equipped with a fiber separation unit 13, which is made in the form of a tank 14 divided by partitions 15 with adjustable gates 16 into separate compartments 17 for the fibers of the respective layer, each of which is connected by a branch pipe 18 with a corresponding dryer 3, while the metering unit 2 the accumulator 1 is made in the form of an inclined transporter-sub-press 19, to which the fiber separation unit 13 adjoins, and the forming heads 7 on

in the form of vertical chambers 20 with perforated walls 21, which are enclosed in a housing 22, in communication with the atmosphere.

At the outlet of the chambers 20, corrugated shafts 23 that are displaced relative to each other in mutually perpendicular planes are installed, between which a guide stopper 24 is placed.

Lini works as follows.

An indirect fiber enters the fiber accumulator 1 and forms a layer of predetermined thickness with the help of the dosing unit 2, which is fed to the fiber separation unit 13, where the layer is divided into individual fibers entering the compartments 17, and from the latter fiber The air flow enters the dryer 3, where chemical additives are introduced into the fiber and fed to the forming heads 7, which form a multilayer carpet 8, which is fed to the cold-pressing press 9. Then, the pre-pressed multi-layered carpet 8 is formed in length and fed into a hot press 11, after which the finished sheet materials are cut out on format-edging machines 12, and the manufacturing cycle is repeated.

The line provides an increase in the quality of sheet materials and allows a significant increase in their range, and the estimated economic effect is 250 thousand rubles. in year.
