A hydraulic pump 11 is installed at the second output end of the shaft of the electric motor 5 to pump oil into the hydraulic cylinder 10.

Two knife blocks 12 are adjacent to the outlet of the feeder 3. A cutting knife 13 is installed in the immediate vicinity of the blocks 12.

The knife blocks 12, the cutting knife 13 and the lever 9 are closed by a casing 14.

Each knife block 12 comprises a housing 15, which is a flat base 16 made in the form of a rhombus with rounded vertices. At the base 16, a square through hole 17 is provided for the passage of the cut product. On the continuation of the diagonal 18 of the hole 17 symmetrically to its longitudinal axis 19 (which in FIG. 3 is projected to a point in the center of the hole 17), there are two basic elements - holes 20, which serve for mounting and fixing the knife block 12 in the device. On the base 16 of the housing 15, two thickenings 21 are made on the two sides of the hole 17, in which the guide holes 22 are made. In the guide holes 22, a knife frame 23 is mounted with the possibility of reciprocating movement with the plate frame mounted on it parallel to one another knives 24. On two other sides of the hole 17 of the bulge 21 are connected to each other (see Fig. 3) by jumpers 25. In the jumpers 25 are made grooves 26, in which the knives 24 of the frame 23 are placed.

In another embodiment, jumpers 25 may not be made. Their role is played by removable plates 27, in which grooves for the passage of knives 24 are also made, similar to the grooves 26 in the jumpers 25. In the plates 27, additional blind grooves 28 are also made; in which the stabilizer 29 is installed.

Since the base 16 is diamond-shaped, its silhouette is symmetrical with respect to both diagonals 18 and 30 of the hole 17. All the forming elements of the knife block body 15, that is, the holes 20, the hole 17, the bulges 18, the grooves 22 made in them, the jumpers 25, made in the last grooves 26, the base 16, are located symmetrically to the longitudinal axis 19 of the passage opening 17.

Two blind cavities 31 are made in the housing 15 from the base 16 side, dividing the guide holes 22 into two equal length sections.

Adjacent knife blocks 12 are mounted in the device so that the guide holes 22, and therefore the knife frames installed in these holes, are turned 909 relative to each other.

The installation of knife blocks in the device is carried out as follows.

Two knife blocks 12 are selected from the set of interchangeable parts with the desired step for installing the knives 24 on the knife frames 23.

0 The first knife block in the direction of product movement is oriented with bumps 21 towards the outlet of the feeder 3 and put on the rods 32 with the base holes 20, while the hole 33 in the traverse

5 of the knife frame 23 are combined with the axis of the earring 35 mounted on the vertical arm of the lever 9. The second knife block is pre-oriented in the same way as the first. Then the knife block is deployed on

0 180 relative to one (any) of the diagonals 18 or 30 of the hole 17. And, like the first block, install the base holes 20 on the rods 32, aligning the hole 33 in the crosshead of the knife frame 5 with the axis 34 of the earring 35 mounted on a horizontal the shoulder of the lever 9. The knife blocks are installed bases 16 towards each other, while they are in contact with each other

0 by the surface of the bases 16, and the guide holes 22, on adjacent knife blocks, and therefore the frames 23, are turned 90 ° relative to each other. Knife blocks crepe t

5 bolts screwed into the holes at the ends of the rods 32. (Bolts and holes not shown).

In an embodiment of the device, when the jumpers 25 between the guide are absent, the installation of the knife blocks 12 is carried out in the same sequence as described above, with the difference that after installing the first knife block, removable plates 27 and the stabilizer 29 are mounted in it , and only then install the second knife block.

Dismantling the knife mechanism for sanitizing or when changing the device for cutting

0 product in pieces of other sizes is produced in reverse order.

A device for cutting food products operates as follows. The product to be cut is loaded onto table 2. From table 2, the operator manually loads the product into feeder 3 and turns on the feeder. Using the hydraulic cylinder 10, the product is advanced to the knife blocks 12. The knife frames 23 mounted on the blocks 12, by

the arms 9 are oscillated in mutually perpendicular directions. When passing through the holes 17 of the knife blocks 12, the product 24 is cut into a packet of stripes with notes 24 mounted on an oscillating frame 23. The cross-sectional dimensions of the strips are determined by the installation step of the knives 24 on each of the frames 23. Separating the packet of strips into separate pieces is discharged by a rotary cutting knife 13. The cut product is discharged from the device through the opening 36 in the casing 14 into a pallet, trolley or other container. The movement of the product supply by the feeder 3 and the rotation of the cutting knife 13 are synchronized so that at the moment of cutting off the openings 17 with the cutting knife 13, the product supply by the feeder 3 is turned off. This eliminates the crushing of the cut product on the surface of the cutting knife.

If a plastic product is cut by a device, then, as a result of compression and plastic deformation, when the first frame passes through the knives between the product layers, into which it is cut by the first frame, free gaps are formed, that is, the cross section of the hole 17 in the second knife block along the product incomplete. Therefore, with knives mounted on the second block, the product layers are carried into oscillatory motion in the direction of vibrations of this frame with an amplitude equal to the sum of the gaps between the product layers. As a result of friction of the layers against each other during the oscillation process, the quality of the cut surfaces is impaired, and the cut lines with the knives 20 of the second frame are uneven.

The installation of a stabilizer 29 eliminates this negative phenomenon. When the product flows around the stabilizer 29, the product is compacted and gaps between the product layers are selected. The volume of the hole 17 is completely filled. The trailing edge of the stabilizer 29 serves as an intermediate anti-stop against the cutting knife 13. Depending on the plasticity properties of the product, the number and thickness of the knives 24 installed on the first knife frame 23, the number of stabilizers 29 to be installed is selected. There can be one or several.

If the device cuts an elastic or solid product, then stabilizers 29 are not installed.

The design of the proposed device allows its use not only for

slicing food into slices, but also slicing it into pieces of a different shape.

So, for example, if you remove the cutting knife 13 and the knife frame 23 on one of the knife blocks 12 (preferably on the first along the movement of the product), the device can be used for plastification of bacon.

If only the cutting knife 13 is removed and both knife frames are left, the device can be used to cut the product into strips.

The device can be used for chopping cabbage or for slicing a product into slices, for example, in the production of meat products such as chop meat or chop. To do this, both knife frames 23 are removed from the knife block housings. The product is cut with a cutting knife 13 in a plane perpendicular to the feed direction.

The implementation of the device according to claim 1 of the formula ensures complete interchangeability of the knife blocks, which increases the manufacturability of their manufacture due to the unification of casting processes and machining, as well as by halving the standard sizes of casting molds and other special technological equipment and measuring tools. It also increases the ease of maintenance and readjustment of the device by reducing the number of interchangeable knife blocks.

The silhouette of the base of the knife block body is made in the form of a rhombus with rounded peaks. Such a mold is a special case of a mold that is symmetrical with respect to both diagonals of the product inlet, while this mold is one of the simplest ones providing the minimum material capacity of the base of the knife block body.

Claims (3)

In the prototype, the cavity dividing each guide into two sections is made from the side opposite to the base of the knife block body; therefore, in each knife block there are eight points of removal of wear products of the knife frames and guides into the outer space. In the proposed device, these cavities are made from the base side, and therefore, when installing the knife blocks in the device, the cavities overlap with the base of the adjacent knife block body. Thus, the number of outflow points of the wear products is halved, i.e., the contamination of the cut product by the wear products is halved. Half of the wear products accumulate in the insulated cavities and do not enter the external space. Contaminants are removed during sanitization. SUMMARY OF THE INVENTION 1.
