Description

xi about xi

The invention relates to the equipment of public catering enterprises and can be used to cut raw and boiled vegetables and fruits into slices, ...; ..., A device for cutting tubers and potatoes, including a vertical drum with knives attached to it, is known . and channels made in the form of a guide plate.

However, this device does not provide a uniform thickness of the slices, since the supply of the processed product to the cutting zone occurs only under the action of its own weight.

It is also known a device for cutting root crops containing a frame, a cylindrical drum, a rotor with blades, a flat knife with a holder, and disk knives located under it and cross-cutting knives.

This device is characterized by the complexity of the design, and consequently, low reliability in operation and insufficient performance.

In addition, from the Vegetable Cutter there is a disk machine with a housing, a cochlear tapered feed hopper and a supporting disk with a set of knives. A loading device in the form of a circular wedge (cochlea) ensures that the product being processed is wedged between the plane of the rotating supporting disc and the inclined surface of the cochlea. Knives on the disk are cut from the product slices, and the thickness of the slice depends on the adjustable gap between the plane of the disk and the edge of the knife.

The disadvantages of the known device are low productivity, since the number of knives on the backing disk and the speed of rotation of the disk are limited, the uneven thickness and deformation of the cut slices due to the lack of forced supply of the processed product to the cutting zone, and the low efficiency of the drive mechanism due to that the cutting process occurs with short pulses per one turn of the disk, when the knives enter the cutting zone, the rest of the time the working shaft rotates almost without load. After the next cut, the processed product does not have time to move to the supporting disc until the next cut, so the slices are of different thickness, deformed, which does not meet the requirements for their quality. To avoid this, it is necessary to reduce the rotational speed of the working shaft, then the productivity drops, or to force the product to accelerate to the plane of the supporting disk.

In the interval between successive cuts, useful work is not performed, the coefficient. motor power is reduced. This leads to low productivity and increased energy consumption of the known device. The increase in the number of knives on the supporting disk and the speed of its rotation do not provide an increase in productivity, since the time between two slices is reduced and the processed product does not have time to move closely to the supporting disk, which reduces the quality of the slices.

The purpose of the invention is to increase the productivity of the device for cutting vegetables, increasing its efficiency. improving the quality of the product.

The goal is achieved by inserting a gland element to force the processed product to press against the supporting disc, by installing on

The additional shaft of the second supporting disk with knives and, respectively, the second loading hopper and the second discharge tray are placed symmetrically with the main similar elements relative to the vertical plane passing between the two supporting disks and perpendicular to the axis of the working shaft, as well as the introduction of a drive return forward movement of the gland

5 items.

The proposed device is characterized by the mobility of that part of the loading hopper, which is located opposite the working stroke zone (loading hopper) of the knives.

0 (cutting zone). The movable part is spring-loaded, can move back and forth, serves to press the cut product to the supporting disc and increases the speed of product advancement, which allows increasing the rotation speed of the working shaft and at the same time preserving the quality of the slices.

When a knife comes into contact with the processed product, between them occurs

0 friction force, which contributes to the pressing of the product to the cone surface of the bunker. If a part of this surface is mobile and spring-loaded, then during the cutting process, the tubers move down and move it,

5 compressing the spring. After the knife comes out of contact with the product being processed, the gland element returns to its original position under the action of a compressed spring and moves to the bearing disc.

0 the processed product in its zone. This makes it possible to increase the speed of rotation of the disks with an increase in the number of knives on the disk, i.e. provides increased device performance.

5 Doubling the basic elements of the device doubles the productivity: during one revolution of the working shaft, four knives work instead of two in a known device.

0 In addition, the layout of the disks on a common axis relative to each other has been changed: the supporting disks have two knives each, which are located on the same diameter; with respect to the first time, the second disk5 will be returned in its plane by 90 °; when the working shaft rotates, knives of different disks, i.e. the knife of one disk cuts the product, and at this time the knife of the other approaches the cutting zone. This allows for additional

increase in productivity without increasing the power of the drive mechanism — the knives of the additional disk cut the product during idling of the knives of the main disk. In addition, the dynamic characteristics of the device are improved by providing increased smoothness of the rotation of the disks.

The proposed device is also characterized by the introduction into the design of the drive device of the reciprocating movement of the gland element. For this purpose, a system of cams located circumferentially on the side of the supporting disk opposite to the blades is used. The cams draw in on the roller, which, through a lever, transmits movement to the gland element. The number of cams is equal to the number of knives, and they are located along the rotation after the knives so that pressing the product gland element to the supporting disk and returning the element to its original position occurs after cutting the slice with a knife until the next knife approaches the given disk. The presence of a mechanical gland drive instead of using spring energy increases the reliability of the pusher operation, i.e. improves the quality of slicing (the same thickness).

FIG. 1 shows a diagram of the device; in fig. 2 is a view A of FIG. 1 (left support disc); in fig. 3 is a view B in FIG. 1 (right support disk); in fig. 4 is a view of B in FIG. 1 (gland plate); in fig. 5 is a view of FIG. 3 (cam).

In case 1 (Fig. 1), a working room 2 is placed horizontally, rotated by the drive mechanism 3. Two supporting disks A with a set of knives 5 are fixed on shaft 2 (Figs. 2 and 3). Each of the two hoppers 6 has a wedge-shaped shape and an inclined surface of the cochlear shape in the zone against the supporting disc 4. The knives 5 are fixed on the supporting discs 4 on the outer side of the device, and between the discs 4 and the lower part of the body 1 the discharge trays 7 are reinforced.

In the lower part of the discharge bin 6, located below the shaft 2 and against the supporting disc 4, part of the inclined wall of the bunker 6 is made movable in the form of a gland element 8 (Fig. 4), having a rod 9 and a spring 10. The rod 9 is placed in the guide sleeve 11 , the axis of which is parallel to the axis of the working shaft 2. The sleeve 11 is fixed to the housing 1.

FIG. 1.3 and 5, an embodiment of the drive of the gland element 8 from the cams .12 arranged around the circumference of the supporting discs 4 from the side opposite to the attachment of the blades 5 is given. Movement from the cams 12 is transmitted through the roller 13 and the lever 14 sliding in the guide sleeve 15. The spring 10 is placed on the outer side of the guide sleeve 11 between the latter and the lever 14. The axes of the sleeves 11 and 15 are parallel. The drive mechanism 3 of the device is installed at one end of the working shaft 2, but may

0 to be placed in the lower part of the device between the supporting discs 4.

The device works as follows

The drive mechanism 3 rotates the worker

5, the shaft 2c is fixed on it by two opyr disks 4. The processed product (for example, potatoes) is loaded simultaneously into two bins 6, under the action of its own weight goes down, 0 0 is wedged between the rotating supporting disk 4 and the inclined surface of the lower cochlear part of the bunker 6. Strengthened on the supporting disks 4 knives 5 cut off from the processed product

5 slices that are squeezed out through the holes in front of the knives 5 in the disks 4 to the back side of the disks A and removed from the device through the discharge trays 7. Each of the supporting disks 4 is equipped with two knives

0 5, and the disks 4 are displaced in their planes along

relation to each other at 90 ° (Fig. 2 and 3),

so in the break between two slices

on one basic disk 4, cutting is produced by knife 5 on another basic disk 4.

5 The design differences described above provide improved performance, quality and increased efficiency of the device. The latter is achieved by increasing the time spent by the worker.

0 shaft 2 under load for one revolution, i.e. between the operation of the knives 5 of the one supporting disk 4, the knives 5 of the other supporting disk 4 are activated, and in the known device at this moment the working shaft 2 rotates without load and, thus, the working shaft 2 and all the power structures of the device are subject to variable loads. The invention allows to achieve a more uniform load and increase the smooth operation of the device.

The gland element 8 provides compression of the next portion of the processed product to the supporting disk 4 due to the energy of the compressed spring 10 stored

5 when the product is jammed between the disk 4 and the pusher 7 in the time interval between successive sections.

In the process of cutting a slice due to the friction of the knife 5 o, the product moves downward in the lower conical part of the hopper 6 and moves element 8, compressing the spring 10. Another damping device can also perform the spring function.

After the cut of the product is completed and the knife 5 passes through, the product under the action of element 8 due to the energy of the compressed spring 10 immediately moves to the supporting disk 4 by an amount equal to the thickness of the cut of the product, and the next cut provides the specified slice thickness.

Thus, the introduction of the gland element 8 improves the performance of the device and the quality of the product obtained.

It is possible to perform an element 8 with a forced drive for pressing the product to the supporting disc 4 immediately after the next slice cut.

 On the inside of the supporting discs 4, in the course of their rotation, the cams 12 are fixed to the knives 5, which run onto the rollers 13 and through the lever 14 move the plate 8 to the supporting disc 4, and the processed product presses against it, which ensures a stable slice slice thickness. Element 8 is returned to its original position by spring 10.

The invention Improves the performance of the device, increases its efficiency, and improves the quality of processing of the product.
