The present invention relates to food industry, in particular for machines for the production of artificial protein shell, and more particularly, concerns the construction of the forming head, which is an integral part of the forming machine.

Artificial protein sausage casing is obtained by processing collagen containing waste enterprises in the leather industry. Artificial protein shell ensures standard sizes. Thanks to its natural physico-chemical properties it provides long-term preservation of meat products, improves texture: taste and nutritional value, allows you to fully automate production lines, the production not only of sausage, but also various kinds of meats.

Known molding machine containing a forming head, described in the book Production of protein sausage casing. Komlev A.P., Chechetkin P.I., Kopernicki O.A., M.: Light and food industry, 1981.

Die head is used for the formation of collagen mass shell in the form of an endless sleeve of interwoven collagen fibers.

The forming head includes a housing, a rotary and stationary shafts.

The housing consists of two modular parts: the front and back. The front part of the case is made in the form of a cast is punnai details fixed on the cooling drum and filler. In the front part of the housing is mounted feed system mass, consisting of tubes.

The rear part of the body is in the form of iron castings with bores for packing stuffing box and under the seat of the large bearing. Inside threaded under the gland nut gland and the gland nut to adjust the gap between the conical nut front and a large cone rotary shaft. To the rear of the chassis attached device that prevents rotation of the stationary shaft, which consists of a lever and stops, and there are adjustment screws for shaft alignment.

The rear lid is bonded with the front part of the bolt. Between the front and rear housing parts has a water cavity.

Rotary shaft consists of a body with screwed him in a cast iron cone and bronze bushing, which has longitudinal grooves. In the front part of the shaft is small cone, and back - boring under seats thrust and radial bearings. The rotary shaft is driven from the molding machine through a chain transmission.

The fixed shaft is made in the form of bare shaft along the entire length of which is a hole for compressed air. There are a bore under the seats of the bearings, stuffing box and inside is the average diameter of the sleeve. In front of a thickened portion of the shaft cut helical grooves for coupling the collagen fibers. On the other end of the shaft pressed radial and thrust bearings, which raised the adjusting nut. The transition from the thick end of the shaft to the housing under the sleeve is made in the form of a cone.

This die head is used as a prototype.

The main weaknesses of the forming head should include the following. When the head is stationary and the rotary shafts are almost the bearings, the lubricant which is collagen mass, passing through the circular opening between them, but the mass is not fully goes into the molding. The shafts for the same reason, tightly pressed cannot, in the immature fiber along with water washed to waste. The performance of this head is low and the product quality is unsatisfactory.

The technical task to be solved by the invention is to improve the performance of the head and product quality at the expense of other than in the most close to the lectern, the interaction between the stationary shaft and the rotary sleeve. Excluded connection of the sliding bearing and the ablation of collagen mass with water, and with full engagement for forming a shell.

This problem is solved by the fact thatin the head for forming a protein shell, mostly sausage, comprising a housing with a socket having a sleeve located in the housing stationary shaft with a longitudinal hole for compressed air, mounted on the stationary shaft bushing on education relative to the sleeve pipe cracks for collagen mass, and a rotary sleeve, connected with the yoke, which are of tapered roller bearings and helical gear, the supply of collagen mass associated with the middle part of the body, and the cooling system, when this head is equipped with mobile and stationary mechanical seals for mass and water, respectively installed in the middle part of the housing, and seals for water housed in its rear part, and a rotary sleeve is made of a longitudinal groove depth of 0.8-0.9 mm, formed by the teeth with the corner cut 60±2 degrees.

In accordance with paragraph 2 of the formula mentioned mechanical seal is made in the form of a disc, and a movable seal provided with a rubber ring and a stationary seal come pre-loaded spring.

In accordance with section 3 formulas rotary sleeve over the ferrule is connected with the stand-alone engine.

The invention is illustrated by drawings, where

Head for forming albuminous, mostly sausage, includes a housing 1 with an inlet 2 with the sleeve 3. In the housing 1 is fixed to the shaft 4, which is made of the longitudinal hole 5 for compressed air, mounted on the stationary shaft 4 and the sleeve 6 located to the formation of relatively sleeve 3 of the socket 2 of the slit 7 for the collagen mass, and a rotary sleeve 8 connected with the yoke 9, which are of tapered roller bearings 10 bearings and helical transmission 11. The head also contains a supply 12 of the collagen mass associated with the Central part 13 of the housing 1, and the system 14 cooling. In addition, the head is equipped with a fixed end seals 15, 17 and 20 and the movable end seals 16, 18 and 19, these seals are installed in the middle part 13 of the housing 1. The head is also equipped with a movable seal 21 and the stationary seal 22 for water, which is installed in the rear part 23 of the housing 1. At the rotary sleeve 8 are longitudinal grooves 24 a depth of 0.8-0.9 mm, with corner cut 60±2 degrees.

End movable seal 16, 18 and 19 is made in the form of a disk and provided with a rubber ring 25, and the fixed end seals 15, 17 and 20 are made in the form of a disk and preloaded by a spring 26. Seals 15, 16, 19 and 20 provide the provide the tightness of the internal cavity of the housing 1 and prevents the collagen mass in bearings 10. Seals 17 and 18 prevent the ingress of water into the body 1 of the head. The rotary sleeve 8 through the ferrule is connected with auxiliary motor 27.

To the middle part 13 is connected to the pipe 2, in which the molding shell in the tube. In the case of the pipe 2 is made holes in which the set screws 28, with which you can adjust the wall thickness of the shell. The used water goes through the holes 29. In the rear part 23 is made a hole 30 through which water for cooling, and a hole 31 through which the diverted water is used in the wastewater. The head is driven by motor 27 through a coupling 32.

Head for forming a protein shell works as follows.

Include a motor 27 through a coupling 32, the planetary transmission 11, which is located on the holder 9, the head is driven into rotation.

From the hopper under the pressure of 40-50 MPa collagen weight through the filter tubes enters the opening 12 located in the middle part 13. The weight falls on the teeth 24 of the rotary sleeve 8, where the interlocking longitudinal and transverse fibers.

Next, the twisted fiber is held in a uniform circular gap (slit) 7, where the molding forming a membrane in the form of a continuous thin-walled sleeve, pressurized air which is supplied through the through hole 5 in podvigina shaft 4. The screw 28 screwed into the socket 2, allow you to adjust the size of the circular gap 7, which ensures the production of a protein shell with a uniform thickness.

Through holes 14 located in the middle part 13, receives water for cooling the moving seals 16, 18 and 19 of the rotary sleeve 8 of the bearing 10, and through the hole 29 in the middle part 13 of the used water goes into the sewer.

In the hole 30 made in the rear part 23, water for cooling of the shroud 9 of the bearing 10 and the rolling seal 21, and the used water through a hole 31 goes into the drains.

Thus, thanks to the distinctive signs provided otherwise by the interaction of the stationary shaft and the rotary sleeve - possible connection of the slide bearing with full capture of the collagen mass for forming shell and excluded ablation mass of water, i.e. the improved performance of the forming head, and as a consequence obtained the required product quality.
