RU64135U1 - ROLLER CAMERA FOR FORMING STEAM OR FIBER PACKAGES - Google Patents

Abstract

The invention relates to the primary processing of bast fibers and can be implemented in the design of presses designed to form packages of stem, fibrous materials, for example, short flax, hemp fiber or stalks of flax straw, trusts.

An object of the invention is the provision of the formation of uniform in density, easily disassembled packages from a continuous stem or fiber layer.

The stated technical problem is solved due to the fact that the dimensions of the opposite sides of the cross-section of the pressing chamber perpendicular to the axes of the rollers differ from the dimensions of adjacent sides.

Description

The invention relates to the primary processing of bast fibers and can be used in the construction of presses designed to form packages of stem, fibrous materials, for example, short flax or hemp fiber or stalks of flax straw, trusts.

Known press chambers in which the compaction of the material is carried out by changing the initial volume of the press chamber when moving the press plate (as, for example, in the press for forming the fiber - GPV-1, LPK-1M, Moskalev [p.178, 179 1]) or pressing arcs forming the volume of the pressing chamber (as in the PKP-100 press, designed to form packs of linen trusts / straw during harvesting from linen during harvesting [p.183 1]). A disadvantage of the known technical solutions is that they suggest, before the process of directly pressing the package, the formation of a sample of a certain mass or volume and have a complex drive of the working bodies.

Presses are also known in which a rectangular pressing chamber is installed with the possibility of forced swinging relative to rollers supplying a continuous layer of pressed material to the pressing chamber. [2]. A disadvantage of the known technical solution is that it requires the presence of mechanisms of complex construction in order to drive the bale chamber and to bind and unload the bale from the bale chamber.

The closest in technical essence to the claimed solution is a pressing chamber, which allows the method of forming packages, which consists in sealing the package by feeding a limited volume of the pressed material into the limited volume of the pressing chamber through a slot in the edge of the pressing chamber [3].

The disadvantage of this technical solution is that the package along the diagonals of its vertical section, perpendicular to the axes of the rollers, has a different density. This is because the opposite faces of the pressing chamber, located symmetrically with respect to the direction of supply of the pressed material into the chamber through the slit in the edge of the pressing chamber, center the material along the line connecting the rib with the slit with the opposite in the section of the chamber, and along the perpendicular to the diagonal section, the compression force of the material is not uniform. At the extreme points of the diagonal (at the camera corners adjacent to the slit), the packing density is minimal.

An object of the invention is the provision of the formation of uniform in density, easily disassembled packages from a continuous stem or fiber layer.

The stated technical problem is solved due to the fact that the dimensions of the opposite sides of the cross-section of the pressing chamber perpendicular to the axes of the rollers differ from the dimensions of adjacent sides.

The aforesaid is illustrated by the drawing. Figure 1 shows a roller press, which implements the claimed design of the pressing chamber. It is indicated here: 1 - a continuous layer of fibrous material; 2 - roller pair supplying a layer of material through a gap in the junction of the faces of the pressing chamber; 3 - pressing chamber.

The claimed technical solution is implemented as follows: A continuous layer of fibrous material is fed to the roller pair. The rollers create a transverse compression of the layer. At the same time, due to the friction forces between the pressed material and the surface of the rollers, the fibrous layer moves into the pressing chamber through a slot in its rib, where it is compacted during continuous feeding. The difference in the sizes of the adjacent faces of the pressing chamber provides different in magnitude of their reaction forces, which will not allow the compressible material to occupy some kind of stable definite position inside the pressing chamber. It will move according to

reaction forces of the chamber walls. Differences in the reaction forces of the chamber walls will contribute to uniform filling of the chamber. When a certain packing density is reached, the supply of material to the pressing chamber is stopped and the finished package is strapped and unloaded. After this, the formation of the next package begins.

When implementing the claimed design of the pressing chamber, the package is easily disassembled with greater uniformity in density.
