Description

The proposed multi - tsepalnaya machine has the purpose of extracting bast fibers from moistened flax trusts.

Usually, the entire mass of fiber harvested within the Union was obtained exclusively by artisanal means in peasant households, while the initial processing of flax abroad is carried out in special factories equipped with special machines.

The proposed multi-floating machine is intended to replace the costly foreign machines with the equipment that they produce in the Union of raw flax processing plants and is designed for purely factory-made, mass processing of flax.

FIG. 1 shows a general arrangement of a flax milling machine, side view; in fig. 2 shows the same machine in plan and in FIG. 3 shows a cross-section of the machine along mobile devices.

The flaked and dried flax is laid onto the trust on the table g (Fig. 2) so that it rests with its apical parts on two freely seated rollers j-j, of which the upper one periodically, for a short time, rises above the lower; In the hole that is formed, the worker advances a bundle of trusts, which are captured by the rollers and transferred to the slumping shafts j, j ... through which they are pulled and the fire breaks. At the end of the mill there is a pair of smooth rollers 4 rotating at the same speed as the pulling rollers and transmitting to the trust, in the form of a thin cloth, into two obliquely discharged jo joints consisting of two four-bladed drums h- / .... rotating at the same frequency as the upper take-up roll is raised. At a known moment, the planes JO of the drums are rotated towards each other, and flax shifted on them by rolls / falls on an auxiliary conveyor 49 endless belt () 2, worn at one end on the drum / o and the other on roller j / and pulley yo rotating in the direction of the hour hand. Transporter 49 h belt (J2 carry crud flax in the direction of its movement, moreover, in front of the beaters, at the point ji, the belt 92 is pressed by the endless upper belt p /.

dressed on drums (y and Sy, due to which the butt parts of the flax bundles are clamped between the upper and lower belts and fed to the first apical ends of the first breaking device yf. The upper ends of the bundles of lpa passed through the first breaking device are picked up by an endless belt gj pulleys / and () j and are clamped with an upper belt), put on n; k / y g / 4 and f and turning in the direction opposite to the clockwise movement, with people (the butt ends of the flax bundle are released from the clamp with straps and are applied to second pair of three cial drums bonds at the output G13 which will otrepany flax beams from both ends, after which the fiber is removed from the hands of the conveyor. In this processing Koptsev trusts protrepyvayuts once, and the average part- twice scutching in both pairs of drums.

In order to achieve a completely reliable clamping of the fiber between the feed belts, a narrow belt is put in the middle of the upper belt, along its entire length, two narrow belts are sewn on the lower belt, so that a tooth is received on the upper belt, and lower corresponding depression; when the belts are placed on each other, the tooth of the upper belt enters the corresponding depression in the lower one, due to which the flax is clamped tightly. To avoid the possibility of pulling out flax by strong impacts of the mobile drums, throughout these last belts, moreover, they pass between two rows of pressure rollers y / (Fig. 1), which rotate on their axes in two grooves of T-shaped beams .- / (; and .- / ji of which the upper ones, ./ (tightly connected to the bed, and the lower ones can be raised and lowered using the press tool ./Л- 57). The transforming parts of the machine include a number of auxiliary canvases: infinite cloth - / (, put on a drum / o and roller) D, bears unstressed fibers The same blades stretched on rollers 3 are the same for the first pair of mobile drums, j p

The scutching apparatus consists of two pairs of equally identical scutching drums. The lower drums consist of axes / f (fig. 1, 5), pa which are reinforced with two crosses 66 and 67 and a round conical rim, with the latter, bolted, attached to a turned ring 6g, which serves to receive pa flax from canvas t). The crosses 66 and and the rims 6S are covered with sheet iron, and the resulting cylindrical drum serves, on the one hand, as an emphasis for trembling flax, and on the other hand, this drum prevents the winding of the fiber on the main axis b /. Cast iron knitting needles are attached to the crosses 66,6- /, on top of the sheet iron, to which the paralles are screwed. In front of the drum, the drum is inclined to the axis, so that the flax is tightened gradually between the upper and lower drums. In the back part, a solid iron ring, wrapped with sheet iron 7U, is attached to the bilam, c.1. It is used to align the fiber removed from the impact of the billet.

The space between the beams and the cylindrical part of the scutching drums is tightened with a net that prevents the fiber from being wound on the beels.
