Description

The invention relates to the food industry, in particular to devices for cutting lard into cubes in the production of certain varieties of sausages, and can also be used to cut raw or cooked meat, as well as vegetables and fruits.

The purpose of the invention is to improve the quality of the cutting of the product by reducing its heating and smi, improving reliability in operation and reducing electricity consumption.

FIG. 1 shows a device for cutting food products, a general view. isometry; in fig. 2 - drive shaft, section; in fig. 3 is a diagram of the speeds of the cutting knife at the moment of cutting the product; in fig. 4 shows an example of the drive shaft when the guide is made on the cutting knife; in fig. 5 is a scan of the side surface of the hub of the cutting knife shown in FIG. four.

The food cutting device comprises a bed 1, a feeder 2 for feeding the product, two perpendicular knife frames 3, a drive shaft 4 with a rotating knife 5 mounted thereon and an input (not shown). The cutting knife 5 is mounted on the drive shaft 4 with the possibility of additional translational movement along the shaft along the sliding pin 6 in the direction of product movement and returning to the initial position after the end of the cutting stroke. At the same time, the speed of the translational movement of the knife is equal to the feed rate of the product at the time of cutting off the cutting knife 5, formed by the knife frames 3, with the cutting knife 5.

The means for imparting the cutting knife 5 at the moment when the grating formed by the knife frames 3 overlaps with the translational movement along the drive shaft 4 contains a guide 7 mounted on the frame 1, section 8 of which interacts with the cutting knife 5 by means of the stop 9 installed on it. is located along a helix, the axis of which coincides with the axis of the drive shaft, and the angle of elevation is determined by the formula

a arctg,

where V is the linear feed rate of the product, m / s;

ω is the angular velocity of rotation of the cutting knife, s;

R - the average radius of the helix, m

The force closure of the stop 9 and the guide 7 is carried out by means of a spring 10 fixed to the shaft 4 carrying the cutting knife 5.

The guide 7 is made removable and is attached to the frame 1 with screws.

In another case, the guide is placed on the cutting knife and is a closed guide groove 11, which is made on the side surface of the blade 12 of the knife 5. The groove 13 has a section that is made along a helical line, the angle of elevation of which is determined by the specified formula.

On the tide of the bed 1 is installed the finger 14, one end of which interacts

with groove.

The device for cutting food products works as follows.

When the drive is turned on, the feeder 2 feeds the product to the cutting zone, where it passes

through the lattice formed by the knife frames 3, cut into strips. The package of strips is cut into individual pieces by a cutting knife 5. A portion of the product loaded in the hopper of the feeder 2 is fed.

When the cutting knife 5 approaches the stack of strips, the stop 9 mounted on the cutting knife 5 rolls over the section 8 of the guide 7. When the stop 9 moves along the section 8 of the guide 7, the cutting knife 5

slides along the drive shaft 4 along the key 6 in the direction of supply of the product, and their translational speeds are equal, as a result of which the cutting knife 5 cuts pieces off the stack of strips in a plane perpendicular to the direction of supply of the product. After the last row of strips has been cut, the anvil 9 of the cutting knife 5 moves to the upward branch 15 of the guide 7 and returns to the upper position under the action of the spring 10. . On the next rotation of the drive shaft 4, the cycle of translational movement of the cutting knife 5 is repeated. In another case, after cutting off the last row of product strips, when the cutting knife 5 stops overlapping the cross-section of the grid formed by the knife frames, past

the finger 14 passes the top of the groove, and the upper side of the descending portion 16 of the groove 13 slides along the finger. As a result, the knife 5 moves to the upper position in which it remains until

finger 16 slides horizontal portion 17 of the groove.

In this device, the cutting knife moves synchronously with the product being cut at the time of cutting. At the same time, the product constantly moves relative to the plane of the oscillations of the knife frames, and the heat released by the friction of the knives mounted on the knife frames of the product being cut is carried away by the cut strips, thus avoiding overheating of the product and improving its quality.

The exclusion from the composition of the proposed device of the interruption mechanism increases the reliability of the device.

During the pulsating mode of operation, variable dynamic loads arise in the units and parts of the device, the presence of which leads to accelerated wear of parts and their failure. Excluding a pulsating feed reduces the likelihood of a device failing, i.e., increases its reliability.

The pulsating mode of operation is associated with the need to accelerate the product and parts of the feeder from rest to some speed from rest to a certain speed at each turn of the cutting knife. Energy costs for overclocking the product and parts of the feeder are always greater than the cost of maintaining uniform motion. Thus, the use of the invention reduces the energy costs of cutting the product.

In the proposed device, the product is fed continuously and is combined in time with the cutting stroke with a cutting knife. This allows an increase in productivity at a constant feed rate (it is necessary to increase the rotational speed of the cutting groove).

Thus, the proposed device allows high-quality cutting of the food product with its continuous supply, while simplifying the design of the device and increasing its reliability and productivity while reducing the energy cost of cutting.
