Description

The invention relates to packaging equipment and can be used for packaging food, medical, chemical and building powder materials.

A device for feeding bulk material is known (RF patent 2009970, B 65 G 65/40, 03/30/1994). The inventive device for feeding bulk material contains tension and drive drums, rollers, waste heat. A feed stabilizer with streamlined plows that agitate the material, as well as a differential gear kinematically connected to the drive drum, the shaft of which is rotated by a vertical auger and its hollow shaft rotates conical brake blades with spiral winding, is mounted above the waste chute. The disadvantage of this device is the low performance and design complexity.

Known dispenser for bulk materials (RF patent 2014277, B 65 G 65/30, 06/15/1994). The inventive dispenser contains a loading hopper with an outlet in the bottom, separated from the bulk of the bulk material by a camera with transport tracks, connected to the hopper by an inlet window with a guide plate in the form of a wedge and an outlet window with shutoffs, a rotating ring with measuring tanks mounted on the base associated with an elastic system of electromagnetic vibration exciter. To increase the speed of vibrotransportation of the powdered material, transport paths with a certain height step are installed in the chamber, a constant level of material on the paths is set using cutters, to increase the stability of the particle size distribution of the powdered material, a cone grating for removing lumps is installed. The disadvantage of this device is the low performance and design complexity.

Known dispenser for bulk materials adopted for the prototype (SU 1789870 A2, 01/23/1993). The device comprises a loading hopper with an outlet in the bottom, an elastic system and a vibration exciter, in which there is a housing fixed to the loading hopper from the side of its discharge opening, an electromagnetic valve for dispensing materials, a dispensing fitting. The disadvantage of this device is the design complexity.

The technical result of the invention is to simplify the design of the device.

The technical result is achieved by the fact that in the dispenser for bulk materials containing a feed hopper with an outlet in the bottom, an elastic system, a vibration exciter rigidly mounted on the feed hopper from the side of its discharge opening, a housing, an electromagnetic valve for dispensing materials and a dispensing fitting, according to the invention, is elastic the system is made of U-shaped springs and cables located on opposite sides of the housing, forming a movable connection between the transfer nozzle and the housing, vib the exciter and the solenoid valve are mounted on the dispensing fitting, and the joint formed between the housing and this fitting is insulated with an elastic sealant.

The application of the invention in comparison with the prototype allows us to simplify the design of devices of this type.

The dispenser for bulk materials is illustrated in the drawing, which shows a vertical section of the device:

1 - loading hopper;

2 - case;

3 - U-shaped spring;

4 - flexible cable;

5 - elastic sealant;

6 - mounts;

7 - rim of an elastic sealant;

8 - vibration exciter;

9 - the electromagnetic valve;

10 - dispensing fitting.

The dispenser for bulk materials contains a loading hopper 1, to which, with fasteners 6, a housing 2 is attached. The dispensing nozzle 10 is fixed with a U-shaped spring 3 and a flexible cable 4 to the housing 2. On the housing 2 and the dispensing nozzle 10, an elastic the sealant 5 by means of the rims 7. On the dispensing fitting 10, the vibration exciter 8 and the electromagnetic valve 10 are rigidly fixed.

The dispenser for bulk materials works as follows.

Bulk material is fed into the loading hopper 1, then a vibration exciter 8 is turned on. By creating vibrations of the dispensing nozzle 10 relative to the housing 2, the bulk material is intensively fed into it and then into the container. The required volume of material supplied to the container is installed using an electromagnetic valve 10. To reduce dust formation, the device in the joint between the housing 2 and the dispensing fitting 10 is isolated with an elastic sealant 5. By using a U-shaped spring 3 and a flexible cable 4, forming a movable connection between dispensing fitting 10 and the housing 2, simplifies the design of devices of this type. The absence of smooth (narrowing) transitions reduces the likelihood of seals. This is also facilitated by an air cushion in the rectangular passages of the device. Reducing the likelihood of seals improves device performance.

The use of a doser for bulk materials provides the following advantages:

- simplification of the design of the device;

- improving the performance of devices of this type.
