SU25673A1 - Flatting machine for stems - Google Patents

Description

The invention relates to machines for flattening the stems of bast plants, such as: kenaf, canthis, cannabis, arranged as. this was previously known across the direction of the stems movement, on the cable conveyors passing through the flatting fixture. The flattening is made with cheeks reinforced springs or to the roller clamps (green eccentrics or to the intermediate points of the rockers connected to fixed axes. The purpose of the invention is to give A flatting fixture with a minimum weight to a mobile schwinging turbine, which is one unit with the flatting apparatus, at the capacity of the latter is equal to the swinging turbine.

FIG. 1 of a schematic drawing shows a section along the line AB in FIG. 3 flattening machine stalks; FIG. 2- trajectory of a point on a cheating cheek, located not directly under the opposite edge; eccentrics; FIG. 3 is a longitudinal section of a stem flattening machine; FIG. 4- modification of the machine. ..:

In the existing design of the flattening machine, material 1 (Fig. 1 & 3), i.e. stalks of kenaf, cannabis or cannabis are laid out by workers, if possible, in a uniform layer on a moving conveyor consisting of several ropes 3 arranged in parallel, supported by rollers 7. In order to better fix the material on

the conveyor as it passes through the conditioner, the material is pressed from the top to the ropes 2 by cables 5, the number is equal to the ropes 2 and put on the pulleys 4 and o, which can be elastically fed up, thanks to the springs 6.

The material thus fixed moves at a uniform speed in the direction of the arrow and undergoes flattening, being located the length of the stems across the direction of movement.

The flattening device consists of flattening cheeks 6 (Fig. 1), with a straight, convex or undulating surface, mounted on the springs 9, in turn connected 1X to the oppositely rotating hmutily 10 roller eccentric Jfl, sitting on the shafts 12, associated gears 73. The clutches 10 eccentrics L are integral with the rocker arms 14, the ends of which opposite to the eccentrics are pivotally connected to the shackles 15 that can swing around the fixed axes 16. The drive shaft 17 gives the gear gear m 13 and, therefore, both shafts TK.

Both systems, consisting of parts 8 through 16, are arranged symmetrically one above the other and the axis of rotation 12 is in the same vertical plane. The material 7 is subjected to simultaneous squeezing from above and below with the help of the cheeks 8 (Fig.).

. The magnitude of the eccentricity and the speed of movement of the cheek 8, and, consequently, the number of revolutions of the shafts 1 should be chosen so that it is variable in its ve; In principle, the horizontal projection of the velocity of any point on the cheek 8 was, in its average value, as close as possible to the uniform velocity of movement of the material. If these conditions are met, the stems will be crushed with little or no displacement relative to the supporting ropes 2 and 3. If the pressing cheeks 6 are not located directly under the eccentrics, but somewhere else on the parts 14, as indicated by the dotted line in FIG. 1 ,, then the path of any point on the cheek 6 will turn from a circle into an irregular ellipse I, II, III, IV and, in a hinge with an earring 75, will turn into an arc (Fig. 2). The removing cheeks 8 from the eccentrics 11, the load on the eccentrics 11 and the upper part of the trajectory of points II, P1, IV diminishes is made flatter, which is also advantageous, but at the same time, the reverse movement of the cheek must be out of reach of the material, otherwise it will be distorted in the opposite direction of movement, and loading (Fig. 2 and 3).

If the pressure on the roller eccentrics 1J turns out to be significant, and it is more advantageous to keep the horizontal position of the cheeks 8 during the movement, then instead of the hinges and swinging earrings 1-5 there can be applied the second pairs of eccentrics 77, which are exactly the same as the other ones sitting on these same shafts 13, connected by gears 73. This system may represent a benefit over the system as described in relation to the space occupied along the length of the conveyor (Fig. 4).

In this case, the side racks of the mashina 19, bearing the sub-shaft rollers 13, must be removed for a distance that ensures free length of the stems between them. In this case, the whole area is divided into several flattening areas, separated by cables 2. 3,

and the size of the cheeks 8 along the length of the shafts 13 corresponds to these areas. The part, of the stalks, located between the ropes 2,3, will not be flattened, which does not matter. Thus, each ivy cheek 8 in the first case will rest on two eccentrics, and on four eccentrics in a modified version. The clamps of these 10 eccentrics will be integral with the circular cross-pieces 14 (Fig. 4). The side racks of the machine must be connected at the top and bottom with completely rigid frames 20 and 21 bearing the bearings of the 32 shafts 7-3 located between the individual flattening cheeks 8.

Gears 13 are made at the ends of the shafts 12, executed massively, or individual flywheels 23, which accumulate energy during the non-working course and give it away during flattening, which will increase the uniformity of the machine.

Thus, the stems are flattened almost the entire length and automatically transferred to the trepal part of the schwing turbine.

Its performance in compliance with the above conditions, EU will surely be equal to the productivity of the Schwing turbine.

The subject matter of the invention.
