Abstract

The invention relates to the woodworking industry, in particular to the production of wood-based panels. The purpose of the invention is to improve the quality of the plates. Separation node 4 lines are perforated with perforated drum 5 and provided with a cylindrical clamp 11 placed above it with locking grooves 12 arranged radially along the generatrix of perforated drum 5. Perforated drum 5 is made with restrictive plates 13 mounted on its working surface and forming inside perforated drum 5 with a hollow rotor 14. The side planes of the 16 limiting plates 13, respectively, interact with the lateral planes of the 17 fixing basics 12. The cylindrical clamp 11 vypolnen.s (L

Depending on the mass, the particles fly through different parabolas. The separation quality of the particles is controlled by the guide screen 29. When a portion of the particles are captured by a rotating perforated drum 5, the restriction plates 13

The invention relates to the woodworking industry and may find application in the manufacture of wood-based panels.

The purpose of the invention is to increase the quality of the plates.

Pa figs. 1 shows a line, a general view; Fig, 2 - separation unit, side view; in fig. 3 is a section A-A in FIG. 2.

The line includes a dryer drum 1, a hopper 2 with a vibrating feeder 3, a separation unit 4 with a perforated drum 5, mixers 6, a main conveyor 7 with molds 8, a press 9, a drive 10. At the separation unit 4, a cylindrical clamp is installed above the perforated drum 5 11, having locking grooves 12, restrictor plates 13 are mounted on the drum 5, and inside it is a hollow rotor .14, where cleaning blades 15 are installed. Restrictive plates 13 consist of side planes 16, and

locking grooves 12 - from the side

planes 17, elastic pads 18 are installed between the grooves. In addition, a chip preparation unit 19, chip machines 20, bunkers for collecting sorted fractions 21, format-edged 22 and shl are installed in the line. fobal 23 machines, sorting sections 24 and storing 25 manufactured plates. On the perforated drum 5, end walls 26 are mounted with which the suction port is movably connected. 27. To separate the discarded particles 28, a guide screen 29 is mounted on the side of the sorting section 24.

Lini works as follows.

Wood raw material from the chip preparation unit 19 enters the chippers 20. After the chips are produced, they are dried in the drying drum 1, and then fed to the hopper 2, the Vibrating feeder 3 feeds the particles to the separation unit 4. After separate shaving, the facing and middle chips The layer is collected in bunkers to collect the sorted fractions 21, then it is subjected to resinification in mixers 6 and fed to the main conveyor 7 to the molds 8. The chip batches are sent to the press 9, and the finished plates are sent to a format-edger 22. After holding the plate is ground on thin sections 23, and then they are sorted at sorting site 24 and at storage area 25, respectively.

Site separation works as follows.

Wood particles distributed by the width of the vibrating feeder 3 are fed from the hopper 2 with a thin layer to the separation unit 4. The mixture of particles falls between the perforated drum 5 rotating towards each other and the cylindrical clamp 11 and is directed to a fixed air environment. Depending on the . their mass (thickness) particles have

various departure parabolas. Heavier wood particles fly through the lighter, and lighter woody parts of the physicomechanical bonded slabs will lower the standing binder.

tsy - closer. The quality of the separation of the material produced, the rial, is controlled by the guide screen 29. When particles are captured by a rotating perforated drum 5, the restriction plates 13 enter fixing grooves 12, which allows the sorted material to be pressed by elastic pads 18 and inform all dropped particles 28 the same speed at their release. This enhances the particle throwing, increases the reliability of material capture, prevents scatter of chips away from the perforated drum 5. Dust fractions in contact with the perforated drum 5 together with the air flow enter it, and then through the end wall 26 and the suction nozzle 27 they
