Description

Sheeting machines and low tobacco per cord are known in which knife heads, a base unit and a cord filler are used.

The peculiarity of the proposed machine for sheet cleaning and low tobacco is that it is equipped with a device for transporting leaves from the needle to the lower cord, made in the form of a flexible cable articulated with a needle and a reciprocating moving conveyor with pivoting pushers with their blades. A machine of this design increases productivity.

FIG. 1 shows the described machine, side view; in fig. 2- kinematic diagram of the blade head; in fig. 3 is a kinematic diagram of a device for transporting leaves and for charging a cord.

The three-wheeled chassis / mounts a knife head 2 for cleaning and low tobacco leaves, an intermediate flexible conveyor 3, a drive 4 for the machine, as well as a mechanism for automatically inserting the cord 5.

The knife head is driven by a flexible shaft 6 from the gearbox 7. The flexible shaft, through a conical pair 8, leads to the turning of two chain drives 9 and 10, on which the plane-parallel shuffling blades And and 12 transporting tobacco sticks through the needle 13 are hinged The centering of the petioles in the head is carried out by means of a movable frame M with return springs 15 and plate springs 16. A knife 17 is mounted on the head. The scapes mix along the needle the blades that interact with abutting the grooves IS lamellar springs and rych№ 148987-2 -

gami 19 pins 20, which prevent the needle inlet from jumping out during the puncture period and movement of the stalks on it. The head breaks down the tobacco leaves and moves them along the needle to an intermediate flexible conveyor that feeds them through the flexible middle part 21 of the needle to the receiving part of the distributor.

The intermediate conveyor is made in the form of a flexible hose, one end of which is connected to the head and the other to the distributor housing 22. Inside the lower part of the flexible hose, along its entire length, the reciprocating moving conveyor 23 is equipped with pivoting (pivotally fixed) pushing vanes 24 of leaves transported from the head. The drive of the reciprocating moving conveyor with the pushing vanes is carried out by means of a drum 25, which wraps around the lower cable of the conveyor twice. Periodic oscillation of the drum is produced by a rack-and-pinion pair 26, driven by a crank mechanism from the gearbox 7. The conveyor is equipped with a compensating device 27.

During reciprocating movement of the conveyor belt, the pushers move the petioles along a flexible needle, passing them through the holders 28 and 29. The intermediate flexible conveyor delivers the petioles along the needle to the receiving part of the distributor.

The distributor consists of two axle-mounted sprockets 30 and 31 interconnected by a chain drive 32, the movement of which is performed by the ratchet wheel 33. Through the ratchet wheel 35 attached to the slide 34, the ratchet wheel interacts with the finger 36 of a crank mechanism.

On the distributor chain transfer, the pushers 37 of the scapes are placed in the working position by means of the stop bar 38. The distributor is equipped with a device for automatic control of the supply of the wire cheerscaps, consisting of a permanent electromagnet 39 and limit switches 40 and 41. After filling the cord with tobacco leaves along the ratchet dispenser ratchet is turned off all over The strung-up cord is replaced with a new one.

The mechanism for automatically threading a needle into the needle consists of a chain transmission 42 supporting the strap 43, the needle holder and the starting and adjusting device. The chain transfer is fixed to the stop 44 and the gripper-feeder 45. The cord feeding mechanism consists of a drum 46, pressure plates 47, a throw-over roller 48, a guide nozzle 49 and a double-plate clamp 50 with a spring-loaded upper movable part 51 and knives. The feed mechanism is driven by a system of levers 52, 53 and 54 and cams 55 and 56. As it moves, the gripper-feeder engages the end of the cord and feeds it into the eccentric holder of the flexible needle cable.

The proposed machine can be used to mechanize and automate the processes of harvesting and low on the string of tobacco leaves.

Subject invention

A sheet-cutting machine for cleaning tobacco using knife heads, needle holders and a movable seal for moving the cut leaves along the needle to the lower cord, characterized in that, in order to increase productivity, it is equipped with a device for transporting the leaves from the needle to the lower stem. in the form of a basement of a flexible cable connected to a needle and a reciprocating moving conveyor with pivoting pushing vanes.
