Utility Model Disclosure

The goal achieved in the inventive combine for cutting bread is to automatically cut loaves, loaves, etc. on pieces of bread intended for making crackers from them. This simplifies the design of the slitting unit, which ensures the cutting of layers of bread into strips. An additional technical result - improving the reliability of the harvester is achieved by using a simple and reliable design in the blocks of longitudinal and transverse cutting of shafts.

The technical results achieved in the claimed slitting unit and in the declared transverse cutting unit are to simplify their design and increase its reliability through the use of shafts - simple to manufacture and reliable in operation.

The indicated technical results are achieved in a bread cutting machine, including a unit for longitudinal cutting of bread strata with two parallel, counter-rotating shafts made with exciting, moving and cutting stub protrusions joined in a horizontal plane, and a transverse cutting unit located below including a shaft with a set of circular knives and a shaft with protrusions for holding and pulling bread cut by circular knives, further including a bread cutting unit on p fins, moving sliced pieces piece by piece to cut them in the slitting unit, and the slitting unit is configured to cut the layers of bread into strips.

In the combine, a bread-cutting unit for formations can be installed above a unit for longitudinal cutting of strata and equipped with a tray (guides) for moving bread strata into a unit for longitudinal cutting of strata.

The harvester can be additionally equipped with a conveyor belt that moves the layers of bread from the block cutting bread on the layers in the block longitudinal cutting of the layers.

The combine may be additionally provided with guides for moving bread strips from the longitudinal cutting unit to the shaft of the transverse cutting unit, holding and stretching the strip.

In the combine, the protrusions of both shafts of the longitudinal cutting unit and the protrusions of the shaft of the transverse cutting unit can be made in the form of teeth with an angle at the apex equal to or greater than 90 °, forming a crown in the form of an “asterisk”. Such sprocket shafts can be made of a larger shaft

diameter using planing or milling machines and, therefore, have a simple structure that does not require assembly and adjustment of the cutting edges.

The indicated technical results are achieved in a slitting unit with two parallel shafts installed with the possibility of counter rotation, made with projections that engage, move and cut the bread layer, joined in the horizontal plane, characterized in that the protrusions are made in the form of teeth forming a crown in the form of an “asterisk” ".

Such sprocket shafts can be made of a larger diameter shaft using planing or milling machines and, thus, have a simple structure that does not require assembly and adjustment of the cutting edges.

In the longitudinal cutting unit, the angle at the top of the teeth to ensure free exit of bread from the recess between adjacent teeth is advisable to make equal to or greater than 90 °,

In the slitting unit, in order to reduce the requirements for the accuracy of the relative position of the shafts, the teeth of only one of the shafts can be made sharp, and the teeth of the other shaft are made trapezoidal, i.e. with cut tops. In particular, the peaks can be made with flat platforms that will compensate for the mutual misalignment of the axes of the shafts for joining their teeth in the horizontal plane.

These technical results are achieved in the cross cutting unit, including a shaft with a set of circular knives and a shaft with protrusions for holding and pulling the bread cut by the circular knives and with annular grooves for passing the cutting edges of the circular knives, characterized in that the protrusions for holding and pulling

the bread cut by disk knives is made in the form of teeth forming a crown in the form of an “asterisk”.

Such a sprocket shaft can be made of a larger diameter shaft using planing or milling machines and, thus, have a simple structure that does not require assembly and adjustment of the cutting edges.

Utility Model Implementation

Figure 1 shows the block diagram of the combine for cutting bread. The unit for cutting bread into layers 1 is located above the unit for longitudinal cutting 2 and is connected to it by a tray 3. The unit for transverse cutting 4 is located directly below the unit for longitudinal cutting. Sliced bread from the block transverse cutting falls on the conveyor 5, directing it to further processing for the preparation of crackers.

The unit for cutting bread into layers shown in figure 2, contains a plate 2 having a Central hole, which includes a vertical shaft 7 of the drive 8. The plate 2 has a discharge window 9 and an inclined tray 10.

A horizontal disk 11 is mounted on the shaft 7, on which the knives 12 are mounted. The distance between the disk 11 and the upper plane

knife 12, measured vertically, is equal to the thickness of the cut chunk (in working samples - 9 mm).

Scrapers 13 are attached to the bottom of the disk 11, located with a gap from the plate 6, the size of which is less than the thickness of the slice.

The device has a casing 14, mounted on top of the plate 2. The lower horizontal wall of the casing is located with a minimum clearance from the knives 12 and has holes in which the vertical loading hoppers 15 are fixed. The hoppers can have a height that allows you to load two or three loaves of bread. An outer annular wall 16 is attached to the side walls of the casing, and an inner annular wall 17 is attached to the plate 2. Walls 16 and 17 form a slice collection chamber.

The hoppers 15 are provided with internal faces, for example, rectangular in cross section, for cutting bread baked in flat-walled forms. The inner dimensions and edges of the hopper provide free sliding of the product in it under its own weight while simultaneously fixing it against rotation during cutting.

The device operates as follows.

The loading bins 15 are continuously filled with loaves or loaves of bread, which slide down under their own weight and fall onto the disc 11 under the knives 12. When the disc is rotated, the knife cuts into the corner of loaves or loaves fixed from rotation, which implements the generally accepted way to start cutting bread due to its economy: not in a plane, but in a corner. During cutting, the downward slant of the knives deflects the resulting slice downward. At the end of cutting, performed at a high speed of the blade, the knife, when the chunk is torn off, tells it to move away from the center due to the bevel sharpening. Slices on the plate 2 are moved by a scraper 13 into the unloading window 9 and then along the tray 10 fall into the slitting unit.

Figure 3 and figure 4 are photographs giving a visual representation of the blocks of longitudinal and transverse cutting.

Figure 5 shows a side view of the shafts of the slitting unit. The shafts 18 and 19 are made with exciting, moving and cutting the formation of teeth 20 and 21, joined in a horizontal plane. The top of the tooth 21 is cut, which ensures its best docking with the tooth 20. The teeth on each shaft form an asterisk. Moreover, the angle at the top of the teeth is equal to more than 90 °, which ensures the free exit of the bread strips after they are cut from the formation. To prevent bread from sticking to the shafts, the shafts can be moistened with an emulsifier.

Figure 6 shows a side view of the shafts of the slitting unit. The shaft 22 is made with exciting and moving teeth strip of bread. The shaft 23 is equipped with circular knives 24, which are included in the grooves of the shaft 22 and are used to cut strips of bread.
