Description

The present invention is a two-part ycTpoilcTBO machine, i.e., flattening and peeling and intended to process bast stalks.

The schematic drawing shows a view of the proposed Maschina side.

The proposed machine consists of two main parts: a flattening apparatus consisting of several calenders, one pair of corrugated rollers at the end — for preliminary breaks of the trusts and a peeling (scraping) apparatus, the purpose of which is to receive the flattened straw (previously bruised) and separate the whole wood (campfire). The abrading machine is a combination of continuous webs with scrapers mounted on them, set perpendicular to the direction of fiber movement. From the variable pressure of the scrapers using the upper canvases, the degree of intersection (the depth of approach of the lower and upper blades) from the minimum (at the beginning of the peeling (39),

ki trusts) to the maximum (at the end of the process). In addition, the process is also regulated according to the quality of the trusts.

The processing of the trusts is carried out on the proposed machine as follows. Flax on a trust, or some other, is served on table 1, laid out in a layer up to 3 mm thick and 25 to 45 cm wide, and periodically (up to 30 times per minute) is fed into the first part of the machine, i.e. flatting. The layer of trusts, having passed a series of calenders 3, is flattened along the entire length and at the exit falls under the action of one pair of corrugated rollers 4, with the help of which the wood, which is flattened and broken along the length of the fiber, receives a series of transverse cracks.

When exiting the straightening apparatus of the trust, it falls on the endless web 5, and then to the peeling scraping machine 6, the Endless blades 8, 8a, 9 and 9a with scrapers, one above the other, have a device that allows them to diverge and approach each other with different degrees of tension. wives In the first period of the stripping machine, the upper blades are separated, the lower ones move in the direction indicated by arrow 2, and during this period are the conveyor for the trusts, which passes the clamping rollers 7 located in the middle of the apparatus and is distributed along its length in equal segments. From this moment on, the second period of the stripping machine begins; the movement of the belt with scrapers 8a in the direction indicated by arrow 2 stops and the web begins to move in the opposite direction. The upper blades with scrapers 8 and 9 gradually approach each other, increasing the pressure on the trust, rotating in the same direction as the lower scrapers. To process the middle portion of the batch, the trusts provide for the slow movement of a pair of rollers 7, with which the trust moves (approximately Va length) to the right and left.

The third period of work — the upper blades retract, while the blades 8a and 9a move again in the direction indicated by arrow 2 and throw the bonfire fiber to the exit table 10. In order to ensure

maximum machine capacity; two stripping machines are provided, working alternately. In order to remove the fires that fall out of the trusts, a blower is provided in the stripping apparatus. The drive for the movement of all parts of the machine is carried out either by using a system of chain and gear-type gears, or it is also possible to synchronize the work of individual parts of the mashina with the help of a servomotor.

The subject matter of the invention.

A flatting and peeling mask for treating bast stems, characterized in that the lower web 8a with scrapers located on the side of the mill is designed so that it allows a periodic change in the direction of movement together with the clamping forks 7, while the upper blades 8 and 9 with scrapers moving working branches as canvas 9a in the direction from rollers 7, allow periodic approach to the lower blades 8a and 9a, in order to scrape the stalks clamped by rollers 7.
