Description

The invention relates to dispensers for pasty products and can be used in various industries.

Known dispenser containing a piston cylinder and a system of channels for ⁵ supply, distribution and discharge of the product (1].

However, the disadvantage of the dispenser is the lack of accuracy of dosing. ^t0

The closest in technical essence to the proposed one is a volumetric paste-like dispenser containing a metering cylinder ’with a piston installed in it and a valve nozzle with outlet openings [2].

The disadvantage of the dispenser is also the lack of accuracy of dosing due to the loss of raw materials due to smudges from the dead spaces of the nozzle.

The purpose of the invention is to ensure the accuracy of dosing by eliminating the loss of raw materials.

This goal is achieved by the fact that in a volumetric paste-like product dispenser containing a metering cylinder with a piston installed and a valve nozzle with outlet openings, the nozzle is made in the form of two concentrically arranged outer and inner glasses with conical ends to form an annular outlet channel between the ends and holes for suctioning the product at the end of the inner cup, while the outer cup is spring-loaded to the cylinder.

In FIG. 1 shows a device when the piston moves to top dead center, general view; in FIG. 2 - the same, to the bottom dead center; in Fig. 3 'section aa in fig. 2; in FIG. 4 section BB in FIG. 1. '

The volumetric paste product dispenser contains a tank 1 with a cover 2 and a sleeve 3, a piston 4 with a rod 5 and a valve 6, a cylinder 7 ”a glass 8 and a glass 9 nozzles, tension bolts 10, _{5 of the} spring 11 and 12. In the tank 1 there is a fitting 13, through which comes. product, and in the cover 2 there is a hole for venting. The nozzle is made of two glasses 8 and 9, 10, which also provides the convenience of washing during sterilization of the dispenser parts.

The device operates as follows. _fifteen

Through the fitting 13, the tank 1 is filled with the product (paste - grax with spices). The product penetrates into the oxyd of cylinder 7 and is located above the piston 4. When the piston 4 moves from bottom dead center, when the volume in the cylinder 7 under the piston is zero, through the opening tiya in from a dead zone and there is a suction of a product (the remains from the previous cycle)., At further _{? |;} The movement of the piston increases the vacuum under the piston, which ensures the opening of the valve 6, which deforms the spring 12 through the stem 5. Through the windows e and d (Fig. 4), the product enters the cavity under the piston. ³⁰ Thus, the product is filled in a predetermined volume of the dispenser.

When the piston moves from top dead center down (Figs. 1 and 2), the valve closes under the influence of spring 12. A pressure is created under the piston 4, which moves the nozzle (cups 8 and 9) to a sufficient clearance c, through which a portion ^{40 of the} product is discharged into the windows d (Fig. 3) through the cavity a (Fig. 1).

The tension bolts 10 and springs-11 provide the necessary pressure under the piston 4.

The overlapping of the windows d of the nozzle cup 8 is carried out by the end face of the cylinder 7. This completes the cycle.

The presence of holes (00.2-0.5 mm) in the valve nozzle through which product smudges are sucked off when the piston moves to the top dead center ensures the necessary metering accuracy.

This invention relates to dispensers of pasty products and can be used in various industries. A known dispenser comprising a piston cylinder and a system of channels for feeding, distributing and discharging the product. However, the disadvantage of the dispenser is insufficient metering accuracy. The closest in technical essence to the present invention is a volumetric dosing of pasty products containing a dosing cylinder with a piston installed in it and a valve nozzle with outlets 2. The dosing of the dosing device is also due to insufficient dosing accuracy due to loss of raw materials due to stains from dead spaces nozzles The purpose of the invention is to ensure dosing accuracy by eliminating the loss of raw materials. This goal is achieved by the fact that in a volumetric dosing unit of pasty products containing a dosing cylinder with a piston installed in it and a valve nozzle with outlet openings, the nozzle is made in the form of two concentrically arranged external and internal cups with conical ends to form an annular outlet channel between the ends and holes for suction of the product at the end of the inner cup, while the outer cup is spring-loaded to the cylinder. FIG. 1 shows the device when the piston moves to the upper dead center, general view; in fig. 2 - the same, in the lower dead center; FIG. A-A, FIG. 2; in fig. k section bb in fig. 1. 39 Volumetric pasty dosing unit contains tank 1 with lid 2 and bushing 3, piston with rod 5 and valve 6, cylinder 7 cup 8 and cup 9 nozzles, tension bolts 10, springs L and 2. Tank 1 has a fitting 13, through which enters. product, and 8 cover 2 has an opening for air release. The nozzle is made of two glasses 8 and 9, which also provides the convenience of washing when sterilizing dispenser parts. The device works as follows. Through fitting 13, tank 1 is filled with the product (pate - grax with specialties). nponyj T penetrates into the cylinder 7 cylinder and is above the piston C. When the piston moves from the lower dead point, when the volume in the cylinder 7 under the piston is zero, through suction from the dead zone a suction of the product occurs (residues from the previous cycle) . Upon further piston movement, an increase in the formation under the piston occurs, which ensures the opening of the valve 6, which through the rod 5 deforms the spring 12. Through the windows e and e (Fig. 4), the product enters the cavity under the piston. Thus, the product is filled with a given volume in the dispenser. When the piston moves from the top dead center downward (Figs. 1 and 2), the valve closes under the influence of the spring 12. Under the piston C, a pressure is created which moves the nozzle (glasses B and E) to a sufficient gap c, through which a portion of the cavity of the product is discharged into the windows d (Fig. 3) a (Fig. 1). 2 Tensioning bolts 10 and springs 11 provide the creation of the necessary pressure under the piston 4. The windows of the d cup 8 of the nozzle 8 overlap with the end of the cylinder 7. This ends the cycle. The presence of openings (00.2-0.5 mm) in the valve head, through which product stains are sucked in when the piston moves to the top dead center, provides the necessary metering accuracy. Claims of volume paste dosing device containing a dosing cylinder with a piston installed in it and a valve nozzle with outlet openings, characterized in that, in order to ensure dosing accuracy by eliminating losses of play, the nozzle is made in the form of two concentrically arranged outer and inner cups with the ends of a conical shape to form an annular outlet channel between the ends and the suction holes of the product at the end of the inner cup, while the cup is spring-loaded to the cylinder.
