Description

The invention relates to the textile industry, and in particular to devices for stapling bast crops, and can be used in the processing of bast crops in various forms.

A device is known for stapling flax fiber in a tape (US Pat. RF No. 2144593, class D01G 1/00, 1999), containing feed rollers for feeding fiber into the working chamber. Inside the casing of the working chamber, drums having radially spaced beating strips are mounted on shafts connected by gears and rotating synchronously in one direction, while the casing in one of the end surfaces has cutouts for supplying fiber, and on the side surface there is an outlet for air-fiber mixture, the number of scuffing drums is more than two, and the beat bars on each drum are installed alternately in two planes parallel to each other and perpendicular to the axis of rotation.

A disadvantage of the known device is the inability to staple bast materials in the form of whole and tangled stems of varying degrees of aging, washed stems, and also fiber in bulk. In addition, the beating strips installed on each of the two drums alternately in two planes parallel to each other do not provide an allowable spread of fibers along the length, which during further processing worsens the quality of the products made from it. In addition, the narrow cutout for the fiber supply and also the length of the working part of the slats do not allow the processing of bast crops with high productivity.

A device for stapling flax fiber in a tape (US Pat. RF PM PM No. 47368, class D01G 1/00, 2005, prototype), comprising feeding rollers for supplying fiber to the working chambers, which is a casing with an exit for removing the stapled fiber, and synchronously rotating scraper drums with beater bars located inside the working chambers, the plane of rotation of which is located at an angle to the horizontal, and for introducing the tape into the processing zone in the casing there is a groove with an adjustable width.

The disadvantages of this device are similar to the disadvantages of the previous known device.

The objective of the invention is to provide a machine for stapling bast crops, ensuring the efficient execution of the technological process of stapling bast crops.

The technical result from the solution of the problem lies in the ability to process bast crops in various forms with high productivity and reducing the cost of fiber.

The objective of the invention is achieved by the fact that the machine for stapling bast crops, containing a feed conveyor, feed rollers for feeding fiber into the working chamber, which is a casing with a groove for introducing raw materials into the processing zone and with an exit for removing the stapled fiber, made in the form of a plate with sharpened cutting edges of at least two, located in one plane at an angle to the horizontal, equipped with two working bodies in the form of plates located on one line relative to each other with a minimum gap between them and rotating synchronously.

Since stapling whole, tangled or washed stalks of bast material, as well as fiber in the mass requires considerable efforts, installing two working bodies on the same line increases the power supply width of the machine and makes it possible to equally effectively influence the processed material along the entire width of the conveyor, cutting it to the desired length at high process productivity and low cost of the resulting fiber.

The invention is illustrated by drawings.

In FIG. 1 shows a machine for stapling bast crops, front view; in FIG. 2 - the same, top view; in FIG. 3 - same, right view; in FIG. 4 is a diagram of the processing of bast crops.

The staple basting machine consists of a feed conveyor 1, feed mulberry rollers 2, a working chamber 3, which is a casing with a groove 4 on its end surface for introducing raw materials into the processing zone and with an exit 5 on the side surface for removing the stapled fiber, inside of which two working bodies 6 are installed vertically on horizontal shafts, made in the form of plates located in the same plane on the same line with a minimum clearance between them, so as not to collide with cutting edges of at least vukh, sharpened in one plane at an angle to the horizontal, and the feed conveyor 1 is installed between the working bodies 6 perpendicular to the plane of their location, the drive 7, which includes the engine with V-belt drive.

Machine for stapling bast crops works as follows.

Bast cultures in the form of handfuls, a layer, a tape from a roll or bale are fed through a feed conveyor 1 to the muller rollers 2, which disrupt the connection of fiber with wood, feed material into the working chamber 3 through groove 4 and hold it during processing. In the working chamber 3, the material is subjected to impacts from the sharpened cutting edges of two flat working bodies 6, mounted on the same line with a minimum clearance between them and rotating synchronously, as a result of which half the width of the material is simultaneously cut to the desired length by one working body, and the rest of it it is cut in width by another organ. The cutting process takes place in one plane and at a certain angle of inclination of the cutting edges to the horizontal plane, which ensures fiber rejection from the center of rotation of the working bodies 6 to the periphery of the working chamber 3. The resulting fibers, together with the fire and dust, are removed from the working chamber 3 through the side exit 5 by a stream air created by the rotation of the working bodies 6 drive 7 and a fan.

Thus, the use of the proposed machine for stapling bast crops will significantly increase productivity and reduce the cost of fiber.
