Abstract

The present invention relates to a rubber sealing apparatus for vertical handheld doors, which, when placed in a press compartment, can also be subjected to hydraulic or pneumatic pressing, in addition to the mechanical operation of the handpiece. With this, handheld presses can be used with new technology, with less physical work and higher performance. -1-

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for vertical grape and fruit presses.

Pressurizing devices are used to extract the must and the fruit juices, i.e. to separate the juices from the fibrous material.

Manual presses, as well as motorized presses of various solutions, have been developed for the extraction of grape must and fruit juices. Hand-operated machines are typically small-scale and our machine-driven machines are designed and used to meet the needs of large-scale businesses, mainly with horizontal layouts.

For small-scale presses, in addition to a good sense of mustache, the first and foremost factor is the reliable, simple design with virtually manual operation. Vertical presses have been developed for this purpose and their use is widespread. These include a spindle mounted on a horizontal press plate surrounded by a wooden basket.

Various diaphragm press devices are known for fruit pressing, most of which are closed container designs, either piston-operated or cylindrical. In these cases, the evacuation of the marc is difficult, their construction is complicated and thus expensive.

The extruded material to be pressed into the basket is extruded by a press mechanism with a mechanical design, a press plate or a press plate. The material loaded into the press basket is pressed downward by the hand-driven spindle-driven press head and as a result, the must flows through the openings in the basket rails.

It is expedient to first apply smaller pressures and then gradually higher pressures in the extrusion process.

During pressing, rotating the press head requires several mechanical presses, with downtime corresponding to the must-turn of the must, ie intermittent operation of the press.

After pressing, the compressed squash should be lifted, crushed and crushed, and the loosened squash should be refilled into the chopping basket for further injection.

Since this process has to be repeated several times depending on the extrusion requirement, the specific basket capacity of the presses of this system is low.

In order to increase the performance and make better use of vertical manual presses, it is necessary to develop a printing device which can be used to perform this task in a simple manner.

This is accomplished by the design of a rubber-ring printing apparatus suitable for vertical manual presses.

SUMMARY OF THE INVENTION The present invention relates to a sealed rubber hose printing apparatus which, when inserted into the basket space of vertical manual presses, is preferably actuated by a pressure medium at each stage of the extrusion, gradually expanding the material in the basket into a suitable shape.

The advantage of this is the more efficient utilization of the press basket volume, which results in increased performance and at the same time saves physical labor.

The pressing device is a flanged cylinder which can be mounted on the spindle of a manual press and is fitted with a rubber hose with a closed space design and an internal pressure chamber is connected to it.

The printing apparatus can be used to develop an advanced version of vertical hand presses as an integral unit, or as a subassembly for practical hand presses, preferably with size variants.

An embodiment of the printing device according to the invention is illustrated in the accompanying figure.

On the first press plate I is located the folding press basket 2, which is bordered by the press plates 3 on the top. The press plate is moved by means of a rotating press head 5 which is mounted on a spindle 4 fixed in the press plate.

Rubber hose nozzle padding on spindle 6 mounted on spindle 6, enclosed space design! consists of a double-walled rubber hose and an upper locking ring S. The pipe 9 is connected to the interior of the rubber hose, depending on the version, with fittings 10 with safety devices.

Operation of vertical hinged press with rubber hose.

Filling the hand press basket 2 with mash a

3. in the upper or lower position of the pressure plate. After the basket is filled, by rotating the press head 5, the pressure plate closes the basket space at the top and then presses down on the material in the basket space further downstream, causing the extruded must to flow through the gaps between the basket racks. This mechanical extrusion may be repeated at intervals of approx. to the position of the pressure plate occupying the upper third of the press basket.

This relatively lower compression phase, which requires a lower compression force, is provided by the space chamber; actuation of the existing rubber hose pressure equipment. The sealed-off rubber hose 7 on flange 6 is then pressurized through the pipeline to the desired pressure value with liquid or air. Gradually, the pressure in the closed interior of the rubber hose clamps the mash surrounding the expanding rubber hose radially and partially axially to the inner surface of the press basket. The resulting compression force releases the mustard inclusions by changing the direction and can be extracted from the continuously thinning ceficaceous material at lower pressures.

Depending on the degree of extrusion, the number of crumb loosening and mechanical re-pressing by transhipment used to date is reduced, cut off completely.

When the press is completed, the conventionally pressed hand presses have a hollow, relatively thin-walled roller shape instead of a pressed cake, which is much easier to remove after opening the basket by slotting.

With the printing device according to the invention, the mechanical operation of the manual presses can be accomplished by hydraulic or pneumatic pressing. This allows manual presses to be used in a new technological process with the beneficial effect of increasing performance and saving physical labor.
