Abstract

FIELD: woodworking industry. The purpose of the invention is to improve the quality of the formed package and ease of maintenance of the device. In the device case (K) 1, sieves (C) 2 and 4 are installed one above the other, and C 2 is made with smaller apertures than C 4 and has a device 8 for moving it. A vibrator 9 is connected to C 1. Under C 2, a sensor 7 is located to control the weight of the fine fraction (MF) of the material being screened and interacts with a device for moving C 2. C 2 is made up of separate parts, each of which is fixed on axis 3. All parts C 2 can rotate simultaneously. Sensor 7 is made in the form of a spring metal plate installed parallel to C 2 with the possibility of changing its length. The boot device is made with a dispenser 5, under which on K 1 is located the distributor of the supplied material in the form of a louvered grille - a dissector 6 in the shape of a truncated cone. With the vibrator 9 turned on, the MF passes through C 2 and 4 to the pallet 10, forming a layer of MF. Upon reaching a predetermined mass or thickness of the MF, the sensor plate 7, bending, is in contact with the device 8 for moving parts C 2. The latter, simultaneously turning, open and the large fraction spills onto C 4 and the pallet 10, forming layer 12. C parts 2 the next mass of material is sifted from the dispenser 5 and the dissector 6 into C 2. 2 hp ff, 1 ill.

The invention relates to devices for making multi-layered bags of wood chip material and can be used in the wood pulp industry.

The aim of the invention is to improve the quality of the formed package and ease of maintenance of the device.

Fig. 1 shows a device for forming a package of a wood chip material.

The device includes a housing 1, an upper sieve 2 with a smaller hole size, made from separate parts, each of which is fixed on axis 3, and completely installed with the possibility of simultaneous rotation, a lower sieve C with a larger hole size, located under the sieve 2 with a smaller size of openings, a loading device with a dispenser 5, a dispenser for the supplied material, located on the body under the dispenser 5 and made in the form of a louvered grille - a dissector 6 in the shape of a truncated cone, the top of the cat The sensor is facing the dispenser, a sensor 7 for controlling the weight of the fine fraction, made in the form of a spring metal plate located below the sieve 2 with a smaller hole size parallel to it and with the possibility of a switch (not shown) of the device 8 for the simultaneous rotation (movement) of the sieve 2 with smaller holes. The vibrator is connected to the housing 1. The length of the spring plate 7 can be varied to control the thickness of the fines layer.

The device works in this sequence.

From the feed dispenser 5, the wood chip material is poured onto an adjustable louver divider 6 in the form of a truncated cone on a sieve 2 with small holes with the closed

The coarse fraction wakes up on C b and the pallet 10, forming layer 12. The parts C 2 are closed, and the next mass of material is sifted out of the batcher 5 and the splitter 6 on C 2. 2 hp ff, 1 ill.

the position of its parts in a horizontal position over the entire area of the sieve.

With the vibrator 9 turned on, the fine fractions pass through the sieve 2 and the sieve onto the pallet 10, forming a layer 11 of small fractions.

Upon reaching a predetermined weight or thickness of filling the fine fraction, plate 7, deflection, comes into contact by means of a switch (not shown) with a device 8 for moving parts of the sieve 2, which are simultaneously turning on the axes, are opened and a large fraction is spilled onto the sieve and the tray 10, forming the layer 12, after which part of the sieve 2 is closed due to the return stroke of the device (drive) 8.

From the feed dispenser 5 and the dissector 6, the next volume of material is sifted onto the sieve 2. Passing through sieve 2 and sieve 4, the fine fraction forms a layer. The cycle is repeated. The resulting multi-layer package after removal of the device or the pallet is compressed.

The device works with manual or automatic mode.
