The invention relates to shredding-food products intended primarily for cutting meat with bone mills, in stores, meat markets, and the like.

. izvest 1Y band saws for sawing bone with bone in portions 1

The disadvantages of band saws are their greater danger to the staff, since it is impossible to close the working area completely / quite frequent breakages and breaks of the thin saw blade, a relatively large amount of sawdust. (2-3% of the mass of sawn mass), ugly, in sawdust cut of meat and greater energy intensity.

The closest to the proposed technical essence and the achieved effect is a device for splitting food products, containing a table for laying products, vertical guides mounted for movement in a vertical plane along the knife guides and a drive mechanism.

In this case, electromagnetic drive motors are used as the drive mechanism of the knife.

For cutting masa per worker

knife travel with maximum resistance to chopping (for example, in the case of chopping the head of a large horn of that cattle) the knife should have a kinetic force of impact of 110–120 kgm. In order to chop off one portion of meat, a device with such an engine must produce a series of knives with a knife, resulting in an uneven cut of meat, which impairs its marketability and reduces the performance of the device. The performance and manual operation of cutting an unharmed machine is negatively affected, since the knife at the end of the working stroke does not touch the plane of the table with the blade. To increase the impact energy of the knife in the device is impractical due to a significant increase in energy intensity.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that in a device for cutting out pigment products containing a table for laying products, vertical guides mounted for movement in a vertical plane along the knife guides and the drive mechanism, the latter consists of a pneumatic cylinder and an electric motor rigidly fixed on the plate, in this case, it is rigidly connected to the pneumatic cylinder rod and connected to the electric motor by means of a movement mechanism containing flexible couplings.

In this case, the movement transmission mechanism contains drive drums, which are mounted on a shaft mounted on a plate and connected via a reducer and a coupling to the motor shaft, while the flexible connections are connected to the drive drums by one end and the knife to others.

In addition, the counter-knife is fixed on the table.

FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 section bb in fig. one ,

The device for cutting food products comprises table 1, to the frame 2 of which, adjacent to the table end, are fixedly fixed a fixed counter-knife 3, an inclined tray 4 (figure 2 for receiving chop-off portions of meat, two vertical guides 5 and two carrying columns 6 (FIG. 2), on which the steel plate 7 is fixed. On the plate 7 a pneumatic cylinder is mounted

8, the rod of which is connected to the blade holder by the knife 9 of the knife 10, which is mounted with the possibility of reciprocating motion along the guides 5. On the plate 7 there are also mounted bearing supports 11 in which the shaft 12 is mounted with two driving drums 13 connected by means of flexible st Zey ,, for example, traction steel tapes 14. with a knife-holder 9. Through the coupling sleeve 15, a shaft 12 communicates with. shaft worm gearbox 16, which through the coupling 17 (Fig. 3} is connected to the electric motor 18 (Fig. 3).

The food splitting device works as follows.

When the motor 18 is turned on, the torque is transmitted through the coupling 17 to the gearbox 16 and through the coupling 15 rotation is transmitted to the shaft 12 with the reel 13, winding strips 14 are wound on them and dragging the holder with the knife 10. The movement of the pneumatic cylinder 8 attached to knife holder

9 is transmitted to the piston, and the latter, lifting, compresses the air in the pneumatic cylinder to the rear pressure.

Before the piston is raised to the top position in the cylinder, there is some overpressure of air obtained from the air line. When the set height of the knife and the set pressure in the pneumatic cylinder are reached, by reducing the air volume, the end switch is actuated, the electric motor 18 is turned off and the knife 10 stops. To execute the knife 10, the operator disconnects the drum and gearbox shaft 15 whereby the knife 10 is fired with compressed air. Moving at high speed over the guide 5,

knife 10 cuts off a quarter of the desired portion. At the end of the working stroke, the movable knife 10 overlaps the fixed contour of the knife 3 by 10-15 mm, after which the pneumatic deceleration of the entire movable element of the device occurs, which prevents rigid removal of the amp; the moving parts of the device are fixed. A severed piece of meat; it is moved with a movable knife 10 into an aklonny tray 4, through which it is scraped into a container.

The kinetic force of impact of the movable knife 10 can be adjusted over a wide range depending on the type of parts being cut through the carcass, either by raising its height or by changing the air overpressure in the pneumatic cylinder while the piston is at the bottom. The pneumatic cylinder is continuously connected through a pressure regulator to an air line or to an air or high-pressure nitrogen cylinder and

The loss of air pressure in the pneumatic cylinder below the allowable (initial excess) automatically rises to the norm.

In this device, the kinematic energy of the impact of a moving knife can reach 120 kgm. This means that the device is capable of chopping any part of the cattle carcass in one knife stroke.

0 with a maximum resistivity of 30-40 kn m. At a cut off of one portion of meat when raising the knife by 425 mm at a speed of 10 m / min and for a working stroke at a speed of 9.7 m / s

5 it takes 3 seconds, i.e. the device is capable of making 1200 working strokes, its performance per shift is 8640 servings.

The design of the proposed device eliminates underburner sa due to

0 high speed of the rolling knife during the working stroke and overlapping one knife by another.
