Description

one

The invention relates to equipment for the production of semi-finished meat products, in particular, devices for cutting raw material into pieces in the production of stews, soup kits and similar products.

The purpose of the invention is to reduce the loss of raw materials.

In addition, the proposed device allows several times to increase the cutting speed of the raw material, which also helps to reduce the number of chips during the shear. At the same time, the dynamic characteristics and indicators of the nodes are improved, the reliability of their operation and of the whole device is improved.

FIG. 1 shows a diagram of the proposed device; in fig. 2 - device, plan view; in fig. 3 shows a section in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 is a view of B in FIG. one.

The device consists of a frame 1 on which the receiving inclined chute 2, the feed mechanism 3, the cross-cutting mechanism 4, the fixing device 5, the fixture 6 for moving the raw material from the cross-cutting mechanism to the slitting mechanism, the slitting mechanism 7 and the electric motor 8 are mounted.

The feed mechanism 3 consists of a frame 9 mounted on a shaft 10 with the possibility of swinging and having a gear drum 11 on the other end. The drum 1 receives rotation through a pulley 12, a V-belt, a pulley 13, a shaft 10, an overload coupling 14, gears 15, a pulley 16, the V-belt and the pulley 17 mounted on the camshaft 18.

The mechanism 4 transverse cutting consists of a shaft mounted in bearings, on which are placed the cutting knife 19, working in tandem with a fixed knife 20 mounted on a frame, a cam 21 and an asterisk 22.

The rotation of the shaft is communicated via a chain transmission to the sprocket 22 from the sprocket 23, the shaft 24, the gear wheels 25 from the camshaft 18.

The fixture 5 for fixing the raw material consists of an upper lever 26 with a limiting bracket 27, a roller 28 and a spring 29, a lower lever 30 with a shoe 31, a spring 32. Levers

26 li 30 have the ability to swing around a common axis 33.

The device 6 for moving the raw material from the transverse cutting mechanism 4 to the slitting mechanism 7 consists of a rotary mounted drum 34 with vanes 35 and an annular notch 36, a guard 37 and an asterisk 38, connected 0 by a chain with an asterisk 39 of the camshaft 18. Mechanism 7 longitudinal cutting comprises a flat, rotatable knife 40 mounted with the possibility of approaching

15 in an annular chamber 36 and paired with a supporting knife 41 of a drum 34, a shaft 18 mounted in bearings, on which a cutting knife 40, an asterisk 39, a gear wheel with 25, a pulley 17 and a pulley 42 connected by a V-belt with a pulley 43 mounted on the motor shaft 8.

The device can be completed

25 universal trolley 44 for collecting the resulting product.

The device works as follows.

M juice is stacked in

30 receiving inclined chute 2 and slides along it to the toothed drum 11, snaps into the teeth of the drum and comes 51 towards the stop 45 against the surface 45 of the drum 34, then it triggers and

35 begins to slip the safety clutch 14 on the shaft 10. The feed rate of the raw material to the stop is controlled by adjusting the diameters of the pulleys 16 and 17 so that the beauty of the pulley

40 was supplied at a predetermined time at the required value, besides, the fine raw material has sufficient rigidity, and the rotational speed of the drum is several times lower than the frequency of rotation of the knife, which allows to cut pieces of the desired size and orient them in the drum.

A fixture 5 for fixing the raw material under the action of the cam 21 presses the supplied raw material, and the cutting spiral knife 19 cuts off the strip Cf, which is picked up by the blade 35 of the drum 34 and moves upwards to meet with the cutting spiral knife

55 40 of the slitting mechanism 7, while the knife 40 enters the recess 36 and cuts the strip into six pieces, which with further rotation of the bar3

The ban 34 under the influence of gravity forces falls into the trolley 44. The enclosure 37 does not allow the pieces to fall out until reaching the lower position. The cam 21 acting on the tool 5 is set relative to the knife 19 so that at the start of cutting the raw material is clamped and after the end of the cutting is released.

The cyclical operation of the device and the interconnection of the cross-cutting mechanism 4, the fixture 5 for fixing the raw material, the fixture 6 for moving, the slitting mechanism 7 are determined by the gear ratios of the kinematic chains from one camshaft t8. The drum 11 of the feed mechanism 3, the thickness of the raw material along the chute 2, is self-leveling due to the swing of the frame 9 depending on the thickness of the supplied raw material, and the overload clutch 14 breaks due to the slippage of the kinematic chain when the raw material stops in the cutting knife 19 and turns it on when turning the knife and reducing the feed resistance. The tool 5, by means of a double-lever scheme with an unclamp spring 32, makes it possible to press the raw material, regardless of its thickness, from the cam 21.

The force of pressing of the raw material by the lower lever 30 is not controlled depending on the thickness of the piece during the cutting process, the fluctuation of the magnitude of the force of pressing of the raw material is insignificant, since the release spring 26 and 30 spring 32 has a sufficiently large length. The lever 26 is constantly pressed springOffered 0.9 4.8 Prototype 1.2 6.0

29 through the roller 28 to the rotating cam 21, and the lever 30 in the absence of raw material is pressed by the spring 32 to the limiting bracket 17 welded to the lever 26.

The use of the device 6 for moving the raw material allows the cut-off strip of the raw material to be grabbed with a blade 35 immediately after cutting, orienting it along the length in a horizontal position, in such a position to move the strip under the cutting knife 40 of the slitting mechanism 7, while cutting to create a large bearing surface on both sides from the plane of the cut (which makes it possible to clamp the raw material when cutting with a knife 40), move the pieces of the raw material to the unloading position and unload them under the action of gravity without using additional mechanisms. As a result of orientation and pressing of the raw material during the cutting process, an even cut is obtained without chips and bone fractures, which

25 reduces losses.

The use of the cross-cutting mechanism 4 with a fixture 5 also improves the quality of the cut, reduces the number of chips and increases 30 MOE.

A comparative analysis of the main technical and economic indicators of the proposed device and the prototype device is given in the table. 5 As follows from the table, the proposed device provides a reduction in energy consumption, an increase in productivity and a reduction in the loss of raw materials.
