Description

The invention relates to machines for treating bast fiber trusts.

The existing compact machines have two significant drawbacks: a large number of bends that the fiber undergoes in the rollers, which leads to a loss of fiber strength, and significant pressure on the rollers of the rollers, which adversely affects the fiber yield.

The aim of the invention is to eliminate these drawbacks.

A special feature of the proposed machine is the use of two groups of needle chains, installed on both sides of the transport belt parallel to it, instead of the plastic rollers. The chains move in the same direction as the transport belt, but at a slower speed, with even chains in each group having a speed different from the speed of odd chains in the same group. By virtue of such a device, in the stalks captured by the needles of the chains and pulled between the needles by the action of the transport belt, mechanical effects — bending, scraping, sliding, shifting — are accompanied by the breaking of wood and the core. The same effects take place when processing trusts on existing

m lnyh cars. In contrast, in the proposed device there is no pressure on the stems and the number of bends is significantly reduced.

FIG. 1 shows a machine in longitudinal section; in fig. 2-car in the plan; in fig. 3 - needle, set on a chain link.

The machine consists of an apparatus having a series of endless narrow 5/5 conveyor belts rotating from the blocks 17, seated on axles 18 and 14. AA is fed onto the displacements 16 with a uniformly thin layer. The straps are fed to the trust by two grooved rollers 19, which destroy it in an area equal to the width of the rollers. Next to the rollers, a shaped beam 21 begins which runs along the length of the entire machine and serves at the same time as a shaped beam of the first section of the schwing turbine. The fissure at the exit from the clamping of the rollers 19 is delivered by its industrial part to the shaped beam 21 and by means of the displacements 16 is brought to the mechanism for further processing.

The latter consists of two rows of infinite chains / -2-3-4-5, etc., to the links of which brackets 5a are welded (Fig. 3), carrying needles 8a fixed on them. The rotation of the chains is carried out with the help of sprockets 22 fixed on axles 13 and 14. Spring guides 227 are mounted between the chains.

11. Approximately on / by the width of the machine (Fig. 2), a pulley 20 of the transporting belt 12 is mounted on the drive shaft 15, stirred, Ayush, its trust along the profile beam 2L Transporting, straps 16 bring the trust to the chain mechanism, the needles of which take the stems.

The even chains of each row have a linear speed different from the speed of odd chains. In turn, the transporting belt 12, which moves the trust along the shaped beam 21, has a slightly higher speed than any of the endless needle chains. As a result, the trust receives a certain number of bends corresponding to the number of chains in both rows. As the needles are dragged through it, it is freed from fires.

Subject invention

A machine for treating trusts, equipped with a system of endless conveyors for moving trusts to working bodies and one conveyor conducting a trust through working bodies, characterized in that the working bodies of the machine for separating the phloem from the trusts are made in the form of two groups of needle chains the sides of the conveyor belt conducting the trust and parallel to it and moving in the same direction, but at a lower speed, even of which have a speed in each group that differs from the speed of odd chains same group.
