Description

Rounding machine

The utility model relates to equipment of the food industry, in particular to machines for forming dough pieces, and can be used as part of technological lines at the enterprises of the baking and confectionery industries.

Known analogues 1-5 of the claimed device, each of which contains a drum in the form of a truncated cone, mounted with the possibility of ingrowing; on a vertical shaft, and a fixed spiral groove, with a small gap covering the drum.

None of these analogues provides for the possibility of adjusting the distance between the wall of the trough and the surface of the drum, which would allow the use of a dough rounder for forming blanks of a wide range of sizes.

This is done in a rounding machine with an adjustable trough 6, which is the closest analogue of the claimed invention. The machine contains a conical drum mounted on a bed with the possibility of rotation around a vertical axis. On the racks of the frame around the drum, a groove is installed, covering the drum along a helical line and consisting of a number of docked parts. Each part of the gutter contains a wall and a base, with the base fixed on the frame and adjacent to the drum, and the wall is placed on the base and made with the possibility of displacement relative to the surface of the drum by means of articulated rods. The articulated rods are movably connected to the levers rigidly fixed to the rods, and the rods are interconnected with the possibility of simultaneous (synchronous) rotation. Turns are synchronized in the central adjustment unit connecting the rods according to i.of ... rO. : o, f,

gear means through gear and worm pairs and cardan couplings.

The disadvantages of the closest analogue include the complex construction of the central adjustment unit, which contains a large number of parts that require their high-precision performance and skilled assembly. The technological complexity of manufacturing parts and assemblies is the reason for the unnatural rise in price of the device compared to analogues.

The objective of the proposed solution is to simplify the design and, as a result, reduce the cost of manufacturing the machine while maintaining its functionality, productivity and high quality processing of dough pieces.

The technical result consists in simplifying the design of the rounding machine.

The specified technical result is achieved due to the fact that in a machine containing a drum mounted on the frame with the possibility of rotation around a vertical axis, and a chute covering the drum along a helical line and consisting of joined parts, each of which contains a wall and a base (moreover, the bases are fixed on the frame and adjacent to the drum, and the walls are placed on the bases with the possibility of displacement relative to the drum by means of articulated rods, movably connecting the walls with the steps, which in turn are rigidly fixed wrenches on rods connected with each other with the possibility of simultaneous rotation), the rods are made interconnected using additional levers rigidly fixed to them. These additional levers are connected by additional articulated rods with at least one slider mounted with the possibility of translational movement.

in particular, the slider can be connected to the frame with the possibility of translational movement using a helical gear.

The inventive utility model is illustrated by graphic materials, where in FIG. 1 shows a general view of a rounding machine; FIG. 2, a circuit for adjusting the gap between the wall of the trough and the surface of the drum, FIG. 3 - node central adjustment (section aa in Fig. 1).

The dough rounding machine has the following design. On the frame 1 with the possibility of rotation on a vertical shaft 2 is installed a drum 3 having the shape of a truncated cone. Around the drum are inclined racks 4, forming a frame. On the racks of the frame on the brackets 5, docked parts of the gutter are fixed, so that the gutter covers the drum along a helical line. Each part of the chute contains a wall 6 and a base 7. All the bases are fixed on the frame and are adjacent to the drum, and the walls are placed on the bases with the possibility of displacement relative to the drum. For the last (upper) part of the groove on the racks 4, the discharge tray 8 is fixed.

On the frame racks 4 in parallel with them are rods 9, fixed with the possibility of rotation in the holes of the racks. On these rods are rigidly fixed levers 10, movably connected to the walls 6 by means of articulated rods 11.

The rods 9 are interconnected in the central adjustment unit 12 with the possibility of simultaneous rotation with the help of central adjustment levers rigidly fixed on them 13. These levers are connected by articulated rods of the central adjustment 14 with a translational sliding slider 15. The slider is connected to the frame by a screw drive 16, driven by rotation handwheel 17.

Dough rounding machine operates as follows. When you turn on the machine, the drum 3 is rotationally driven on a vertical shaft 2. The dough pieces from the dough dividing machine are conveyed or manually placed on the first (lower) part of the gutter. The drum, on the conical generatrix of which grooves are made, hooks the workpieces and, scrolling, extends along the chute up the helix. In this case, the blanks take a rounded shape, the structure of the dough becomes more uniform. Having reached the end of the gutter, the workpieces are rolled onto the unloading tray 8, and from the tray they fall onto the conveyor and arrive for subsequent processing.

the rotation of the handwheel 17 is converted into the translational movement of the slider 15. In this case, the slider, using the articulated rods of the central adjustment 14, rotates the levers of the central adjustment 13 together with the rods 9, on which these steps are rigidly fixed. The rods, in turn, rotate the levers 10 that are rigidly fixed to them, which, by means of the articulated rods 11, move the walls of the groove 6 relative to the bases 7 of the groove. So, rotating the handwheel, set the required distance between the wall of the groove and the surface of the drum.

The implementation of the central adjustment unit on the basis of relatively inexpensive unified elements - levers and rods that do not require complex adjustment during assembly of the unit, greatly simplifies the design of the machine, allowing to achieve the claimed technical result.
