Description

one

The invention relates to packaging equipment and relates to a device for forming a package in the form of a parallelepiped used in food industry.

The closest technical solution to the present invention is a device for forming a package in the forefront of a parallelepiped, comprising a rotor with forming chambers, and immobile and movable and movable walls and curtains and heating element 1.,

However, the known device does not provide sufficiently high performance.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by the fact that in the device for forming a parallelepiped package containing a rotor with formed chambers having fixed and movable walls and curtains and a heating element, the fixed wall of each chamber on the outer side has L-shaped fins, and the axis of the movable wall located at the free ends of the ribs, in the upper part of which a cover is installed, made in the form of a plate to which a spring-loaded strap is attached, having a shape corresponding to the upper part of the package, m curtain attached to the middle part of the ribs and each of them is made as a film to which prikreppon $ 1 curly spring loaded curved wall with the guide, and the wall kinematically coupled by toothed sectors.

The device (Fig. 1-5) contains

20 rotor 1 with forming chambers having fixed and movable walls 2 and 3 and left and right curtains, bend 4 and heating element 5. Stationary wall 2 (FIG. 6)

25 each chamber from the outside has 6 L-shaped ribs. The axis 7 of the movable wall 3 (Fig. 7) is located at the free ends of the ribs 6, and in their upper part on the axis 8 a cover is installed, made in the form of a plate 9. K

30 plate 9 is attached spring-loaded by means of a spring 10 plate 11, having a shape corresponding to the top of the package. Curtains (Fig. 8) are attached to the middle part of the ribs (b), each of which is made in the form of a plate 12. A curved wall 14 is attached to each curtain by a spring-loaded figurine spring 13 with guides 15 for the corners of the package. Both curtains are installed with the possibility of rotation around the axes 16 and 17, with the curtain right connected with the levers 18. and the left with the toothed sectors 19. The movable wall 3 is also L-shaped, with its lower part serving as the bottom of the chamber forming mechanism The wall 3 is rotatably mounted around the axis 20 by means of a lever 21, one end of which is fixed to the axis 22, and a gear wheel 23 is located at its second end that fllHuteecH meshes with the gear sector 24, while the walls 2 and 3 of the forming chamber are kinematically by the last one. Stationary relative to the bed (not shown are fixed spring-loaded springs 25 rollers 26 to form the bottom corners of the package. The device works as follows. When the rotor 1 rotates the forming chamber, the approach to position 27 (Fig. 1) opens, the plate 9 folds back, the curtains open and the movable wall 3 is removed. The package at position 27 enters the forming chamber, after which it closes at position 28 (Fig. 1). Then, under the influence of the packaging of the working parts of the device, the side walls of the package are formed and its upper and lower surfaces. Next, using the rollers 26 and guides 15, the lower corners of the package are formed, and with the help of guides 15 and the plate 9 - its upper corners. At position 28 (Fig. 1), the working parts of the device are retracted into the initial position, giving the opportunity to go through the bend 4 and the heating elements 5, while one corner of the package is folded over 135 relative to its side plane, and the other corners 45 over relative to the latter. At the same time, the external polyethylene coating of the corners is heated with the help of heating elements 5. Then the forming chamber at position 29 is closed again, the curtains press the lower corners of the package to the sides, and the plate 9 - its upper corners to the upper surface of the package. Then, with the next rotation of the rotor, the forming chamber is fully opened, and the package is ready, and the package is withdrawn from it to 30 (figure 1). The proposed device for forming a package in the form of a parallelepiped is simple in its design and provides, in comparison with the known device, an increased rate of formation of packaging and, thus, an increase in productivity. Apparatus of the Invention A device for forming a package in the shape of a parallelepiped, comprising a rotor with forming chambers having fixed and movable walls and curtains, a heating element, such as to increase productivity, the fixed wall of each chamber on the outside has the ribs are of the L-shaped shape, and the axis of the moving wall is located on the free ends of the ribs, in the upper part of which there is a cover installed, made in the form of a plate, to which a spring-loaded plate is attached, having a knurling shape, vet item count guide the upper portion of the package, and the shutter attached to the middle part of the ribs and each of them is formed in plate-form, which is attached to spring loaded curly curved wall with the guide, and the wall kinematically coupled by toothed sectors.
