Description

(54) DISPENSER

one

This invention relates to a dosing technique and is intended for dosing viscous materials, in particular. viscous confectionery masses and can be used in food, chemical and medical industry.

A dispenser containing a piston chamber, a hopper, a nozzle, a one-piece spool with two channels, one of which connects a piston chamber with a hopper, and the other a piston chamber with a nozzle, and a drive with gear P. are known.

The disadvantage of such a dispenser is the complexity of the design and the impossibility of depositing viscous confectionery masses.

The aim of the invention is to simplify the design and provide a deposit of viscous confectionery masses.

The goal is achieved by the fact that in a dispenser containing a piston chamber, a bunker, a nozzle, made by RS

But the whole with the nozzle is a spool with two channels, one of which connects the piston c. a bunker, and another - a piston chamber with a nozzle, and a drive with a gear spool made in the form of a cylindrical body mounted vertically with a reciprocal movement along its axis, provided in the upper part with a rail mounted with the drive gear; moreover, the channel connecting the piston chamber with the hopper is made in the form of an annular groove located on the outer surface of the spool, and a channel designed to connect the piston chamber with the nozzle in the form of an axial bore in the spool with a radial branch.

FIG. 1 shows the proposed dispenser; on -fig. 2 - the same, when a viscous confectionery paste is sucked into the piston chamber; on fng. the section along the A-A in FIG. 2, The dispenser contains a piston chamber 1 with a piston 2, a hopper 3, a valve. 4 made in one piece with the nozzle 5, with two channels 6 and 7, the drive with gear 8; Channel 6 connects chamber 1 with nozzle 5. Spool 4 is designed as a vertically mounted, reciprocating movement along its axis of a cylindrical body fitted in the upper part with a rail 9 mounted with the possibility of engagement with gear drive 8. Channel 7 connecting chamber 1 with the hopper 3 is made in the form of an annular groove located on the outer surface of spool 4, and channel 6 in the form of an axial hole in the spool 4 with a radial branch. Through the channel 6 the mass of the confectionery is squeezed out and the confectionery product 10 is deposited. The dispenser works as follows. When the spool 4 is in the upper position through the channel 7 of the confectionery mass, the bunker 3 is sucked into the chamber 1 by a piston. 2. The piston 2 and the spool 4 are driven in a reciprocating motion by the gear 8. At the lower position of the spool through its channel 6, the viscous confectionary mass with the piston 2 squeezes the lines (not shown in the figures) to the conveyor (for example , body of truffle-type chocolates. At the end of the extrusion, i.e., when the piston of chamber 1 is in its lower position, the spool 4 rises abruptly, detaching the viscous confectionary mass from the deposited product 10. again connects the channel m 7 camera 1 with bunker 3. At the same time, S1 is repeated. Thus, the dispenser provides jigging of viscous confectionery masses by making nozzles 5 in one 04 integral with the spool 4, which allows the viscous confectionary mass to be squeezed out with a subsequent separation as the nozzle 5 moves upwards. Performing the drive of the reciprocating piston 2 and the spool 4 in the form of a gear-rake gear pair. - simplifies the design and eliminates the torsional stresses arising when moving them with a lever or a crank mechanism, which leads to unilateral wear and tear. clearances and eccentric production in the spool and piston. DETAILED DESCRIPTION A dispenser comprising a piston chamber, a hopper, a nozzle, integral with a nozzle, a spool with two channels, one of which connects the piston chamber with the hopper and the other a piston chamber with a nozzle, and a gear drive characterized in that , in order to simplify the design and provide jigging of viscous confectionery masses, the spool is made in the form of a vertically mounted with the possibility of reciprocating movement along its axis of a cylindrical body, fitted in the upper part with a lath, connected with the drive gear, the channel connecting the piston with the hopper is made in the form of an annular groove located on the outer surface of the hollower, and the channel designed to connect the piston chamber with the nozzle in the form of an axial bore in the spool with a radial by tap.
