Abstract

Use: for dosing thick mixtures, in various industries for rubber-based materials. Essence: the material from the engine 1 is fed through the die plate in the form of a cord to the inside of the measuring device 2, connected by ends and forming a pipe. When the thick mixture cord fills all the measurements 2, it acts on the sensor 8. The signal from the latter goes to the control panel 4, the 3-displacement actuators turn on, by which two groups of rigidly connected filled measuring units 2 are diverted to the side perpendicular to the movement of the mixture. 3 il.

This invention relates to the dosing of thick mixtures and can be used in various industrial fields for rubber-based materials.

A device for metering viscous materials is known, comprising a housing with a rotor, a plunger and a cam. The body is made in the form of a cochlea, the cut-out is made spiral, and is located throughout the suction phase, and the cam is in the form of a coil with annular grooves on the side surface.

A disadvantage of the known device is the narrow scope. This device works with materials of a certain consistency, which are amenable to absorption, for example, with resins, glue. The device is not suitable for thicker mixtures.

Closest to the present invention is a bulk product dispenser, comprising a housing with two bunkers, a reciprocating moving measuring vessel, two rows of measuring devices and an actuator. On the dispenser case there are magnetic field coils.

The disadvantage of the known dispenser is that it is impossible for them to dispense thick materials.

The purpose of the invention is to expand the field of use by allowing the dosing of thick mixtures.

To achieve this goal, a metering device installed with the possibility of interaction with the feeder, a mixture presence sensor and brackets are inserted into the metering device containing the first and second groups of cylindrical measuring tanks, each measuring device is made with a connector mechanism, the carrier is made in the form of two pairs t g, each of which is connected by brackets with the connector mechanism of a corresponding group of mernik, the mernik of the first and second groups are arranged in a checkerboard pattern, the ends of the first and second merry groups s wife conjugated by sliding fit and the presence sensor is located in a mixture of the latter from the feeder dipstick and is connected to the control panel,

Such a design solution expands the scope of use by providing the ability to dispense thick mixtures as compared with the analogue and the prototype.

FIG. 1 shows a metering device, general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one.

The metering device contains a feeder 1, two rows of measuring instruments 2 with a 3-displacement drive, and a remote control A. Merniki 2. equipped with 5 opening mechanisms,

by means of brackets 6 are rigidly connected by rods 7. The final measuring device 2 is equipped with a sensor 8 for the presence of a mixture. The conveyor 9 is located below the device. The dosing device operates as follows.

The material from the feeder 1 is fed through the die plate in the form of a cord into the measuring apparatus 2 connected by ends and forming a tube. When the thick cord of the mixture fills all the measuring tubes 2, it acts on the sensor 8. The signal from the latter goes to the control panel 4, where it is converted into a command to disconnect the feeder 1. During the pause in the supply of the mixture, the 3-displacement actuators are activated. The filled filled measuring tanks 2 are dispersed to the sides perpendicular to the movement of the mixture. Then the measuring tanks 2 by means of the mechanisms 5 are opened and the dose

portions of the thick mixture fall out onto the moving conveyor belt 9, which feeds them to the next operation, after which the measuring tanks 2 acquire a cylindrical shape and by means of actuators join the ends to form a pipe.

The feeder 1 is turned on and the mixture through the die plate is again fed into the measuring tanks 2.

The use of the invention expands the scope of application of known dispensers.

by allowing the dosing of thick mixtures.
