Description

The invention relates to a packaging technique and is intended to ensure the division of bulk materials into doses using the volumetric method of dosing.

A device for dispensing bulk materials is known, which contains a feed hopper, a rotating material chamber located beneath it and a measuring vessel at the outlet of the latter, made in a rotating ring [1].

This device is highly productive, but it is difficult to apply it to equipment with a capacity of 60–100 packs / min. It is also necessary to have devices that ensure the removal of the dose in the absence of packaging, since stopping the fast-rotating dispenser is not practical. In addition, the known dispenser can work only with stable performance of the filling machine.

The purpose of the invention is to change the periodicity of the dose, which will synchronize the operation of the dispenser with the work of the filling machine at any performance of the latter.

The goal is achieved by the fact that the measuring capacitance is set with the oscillation 2

telny movement in the vertical plane.

FIG. 1 shows a device for dispensing bulk materials; vertical section; in fig. 2 - section A — A on

5 of FIG. one.

The device for dosing bulk materials consists of a bunker 1, a pipe 2 installed under it with a rotating chamber 3 for the material. The pipe 2 is placed in the bearings 4 of the bed 5. At the exit of the chamber 3, the measuring capacity 6 is mounted. The measuring capacity 6 through the thrust 7 is pivotally fixed on the axis 8 located in the pipe 2.

With gear 7 is connected gear 9, which is in engagement with the rail 10.

¹⁵ Traction 11 with a counterweight 12 and a similar gear wheel is pivotally mounted on the same axis 8. The gear wheel of the traction 11 engages with the rail 13. Both slats 10 and 13 are fixed with the ring 14,

2o fixed with a key on the pipe 2 with the possibility of axial movement along it. On the ring 14 is fixed to the bearing 15 with the housing 16. With the housing 16 is pivotally connected thrust 17 with the possibility of swinging

movement in the support 18 of the frame 5. At the other end of the thrust 17, the armature of the electromagnet 19 is strengthened. The thrust 17 is connected to the stanina of the spring “Grastage” and ^. Since the tube 2 s'bo'dyyVDy / Eektora 21, one of which is reinforced x valve 22. On the tube 2 is rigidly fixed pri- ₅ aqueous pulley 23. The outlet 24 is mounted on the frame 5.

The device works as follows.

The drive pulley · 23 receives rotation From the electric motor (not shown in the drawing) and drives pipe 2 with 10 camera 3, measuring capacity 6, sectors 21 and other parts attached to them.

Material from the hopper 1 enters the rotary tube 2 and the chamber 3, from which under the influence of centrifugal forces postu- ¹⁵ drawn through the measuring container 6. The filled metering reservoir for discharging translates to a lower position. For this, the signal received from the time relay of the controller or

romagnet 19, Oh turns the thrust 17 around the support 18. Thrust 17 with its other end lowers the cororg! 16 with the bearing 15 and the ring 14 with turnips 10 and 13. When the ring 14 moves along the axis of the pipe 2, the slats turn gears mutually associated with them, which, through the thrust 7 and 11, lower the measuring capacitance 6 and the counterweight 12.

In its lower position, the measuring capacitance (in the drawing is shown by dash-dotted lines) is unloaded under the influence of gravitational forces on the bulk material. The centrifugal forces acting on the material in this position are insignificant, which reduces the dusting of the material.

After emptying the measuring tank, the electromagnet 19 turns off, and the measuring tank 6 returns to its original position under the influence of the spring 20 and centrifugal forces acting on the measuring tank and the counterweight. Following the outgoing measuring tank 6, the valve 22 closes the outlet opening of the loading chamber 3 to prevent; Schenia rash of material from it.

The total economic effect from the use of the device will be 891.4 rubles.
