Description

 The invention relates to the baking industry, in particular to equipment for the manufacture of dough blanks for lamb products.

 Known installations for the production of ring-shaped dough pieces, containing a conveyor for feeding the dough, calibrating rollers, a mechanism for cutting the test tape into separate bundles, a device for receiving test bundles, a mechanism for forming test rings and a conveyor for receiving them.

 However, they have a long production cycle of the workpiece and a complex structure.

 A known machine for the manufacture of ring billets from dough (ed. St. USSR N 258186), comprising a roll supercharger, a forming head with sleeves, rolling rods freely suspended in the sleeves, forming an annular gap with their inner surface, a rolling device consisting of movable half-sleeves wrapping sleeves, rolling pin lifting mechanism, made in the form of a frame, taken to the side after cutting off the workpiece, control mechanism, which is two lateral traverses with spring-mounted quality mounted on them with levers associated with half-sleeves, a conveyor for receiving shaped blanks and a drive.

 A disadvantage of the known design is the low productivity due to the idling speed of the rolling device (returning half-sleeves to their original position) and the alternate use of the rolling pin for cutting the annular dough piece and rolling it.

 The aim of the invention is to increase the productivity of the machine and improve the quality of the dough pieces by ensuring the continuity of the technological cycle and improve the rolling of dough pieces.

To do this, in a machine for manufacturing annular dough blanks containing a drive, a roll supercharger, a forming head with sleeves and vertically suspended rolling pins, a rolling device consisting of movable half-sleeves, and a means for cutting ring billets, a rolling device operating continuously, is made in the form two vertical chain conveyors carrying rolling half-sleeves. To obtain a high-quality workpiece, the conveyors are equipped with a device that provides gapless closing of half-sleeves and consisting of guides and eccentrics;
In addition, the mechanism for cutting off the annular blanks from the continuously extruded test tube is made in the form of a fixed and movable knife and a stepless speed control mechanism that provides a change in the response frequency and the knife stroke. The roll supercharger is equipped with a stepless speed control mechanism to control the weight of the dough pieces depending on the moisture content of the dough.

 Only the totality of all the above signs can achieve the goal.

 Known machines in which chain conveyors with rolling half-sleeves are used for rolling dough, do not provide gapless closing of half-sleeves during rolling (therefore, they do not ensure the quality of the workpiece), since the radius of rotation of the middle section of the half-sleeve is less than the radius of rotation of the half-sleeve angle.

 Figure 1 shows the proposed machine, General view; figure 2 section aa in figure 1; figure 3 section BB in figure 1; figure 4 one of the sleeves and rolling pins of the forming head.

 The proposed machine contains a roll supercharger 1, a cutting mechanism for the dough pieces 2, a rolling device 3, a through conveyor 4 for receiving the formed blanks on sheets and a drive with an electric motor 5 mounted on the housing 6.

 The roll supercharger 1 contains two corrugated rolls 7 and a replaceable forming head 8 with sleeves 9 and rolling pins 11 suspended on them on spherical joints 10.

 The cutting mechanism of the dough piece 2 contains a fixed knife 12, mounted on the core of the sleeve 9 and forming an adjustable annular gap for the output of the test, freely movable knife 13 sitting on the sleeve 9, connected through a cracker 14 and the fork 15 with the shaft 16, and a device for changing the speed and the amplitude of movement of the knife 13, consisting of a lever with a connecting rod 17, a crank 18 and a friction variator 19.

 The rolling device 3 is made in the form of two vertical chain conveyors 20, carrying rolling half-sleeves 21. To eliminate the bumping of half-sleeves 21 by angles when closing, to ensure their gap-free closing and to give rigidity to the working section, the conveyors 20 are equipped with guides 22 and eccentrics 23.

 The machine is driven by an electric motor 5 through a V-belt variator 24 and a gearbox 25. One chain gear 26 from the gearbox 25 goes to the transfer shaft 27, and the other chain gear 28 to the drive of the conveyor 4 for feeding proofing sheets (not shown). The dispensing shaft 27 is connected by a chain gear 29 with a roll supercharger 1 and a chain gear 30 with an intermediate shaft 31, which is connected through a chain gear 32 to a rolling tool 3 and through a friction variator 19 with a cutting mechanism for the dough piece 2.

 The machine operates as follows.

 The dough through the receiving tray 33 enters the roll supercharger 1. With rollers 7, it is distributed over the sleeves 9 of the forming head 8. From each sleeve 9, a continuous test tube is extruded through an adjustable annular gap formed by the end face of the sleeve and a fixed knife 12 mounted on the core of the sleeve, which the movable knife 13, making a reciprocating motion and running into a fixed knife 12, cuts off the annular blanks and pushes them from the fixed knife 12.

 The volume of the annular workpiece steplessly with the machine running is controlled by a V-belt variator 24, changing the speed of the rolls 7, and a friction variator 19, changing the response frequency of the movable knife 13.

 The annular billet under its own weight falls down, where it is picked up by the half-sleeves 21 of the chain conveyors 20 and, gaplessly closing, rolled along the rolling pin 11. The process of cutting and rolling is continuous. At the end of the working section, half-sleeves 21 open. The workpiece under its own weight falls on the proofing sheets located on the conveyor.

 This design allows you to increase machine performance and improve the quality of the workpiece.
