The “Vitmas” Co. offer PET bottles production equipment with capacity from 0,1 l up to 20 l and various productivity. In this catalogue section there is description of the equipment with productivity up to 3 000 bottles per hour.

Short characteristic of the blowing machines with productivity from 3 000 to 6 000 bottles/h.
The machines with productivity from 3 000 to 6 000 bottles/h are automatic. They are designed for PET containers production for mineral water, sweet drinks, fruit juices, vegetable oils, milk and dairy produce. The “Vitmas” Co. offer a range of highly productive blowing machines of rotary and linear type. Rotary machines differ from linear ones by their advanced constructive functional solutions and, as a result, by reaching high production indices.

General description of the PET bottle production for this class machines.

Preforms feeding. The preforms contained in bulk in a box, at speed adjustable by electronic system, are fed onto a conveyer belt and spade elevator. Then, under gravity the preforms are lined up and fed onto the feeding screw for machine loading.

Preforms transport system. The preforms are placed onto the transport chain, which transfers them to the heating ovens through the carousel with mechanical drive. This carousel takes the preforms from a special shape star.

Preforms heating. Before blowing preforms are heated by means of special UV lamps. At that PET material is softened. The heaters constructive features depend on a machine specific type. The system is made so that to heat the preforms in accordance with required modes of bottles blowing. The temperature control system regulates each preform zone heating till the required temperature degree. This technology allows to optimize material thickness distribution in the blown bottle’s sides.

Preform thermal conditioning. During heating process the upside-down turned preforms constantly rotates to ensure uniform heat distribution. The ovens are blown through to maintain optimal working temperature to avoid overheating of the preform’s outside. The preforms’ transport system allows regulating thermal inversion time still before they come onto the blowing carousel. Thanks to this possibility optimal heat distribution is obtained depending on preforms thickness and geometry, because under inductive heat transfer the preform’s inside part temperature increases, and outside part temperature decreases.

Stretch and blowing. The preforms are fed onto the blowing carousel. Possibility of regulation of moulds thermal mode allows maintaining the temperature of bottle bottom, body and mouth within rates required by blowing process. Preforms axial stretch is carried out by means of rods driven by pneumatic cylinders, which in accordance with beforehand-prescribed parameters, ensures reaching of equal working forces in all blowing sockets. Succession of the process different operations, i.e.: preliminary blowing, blowing and degassing, are obtained by pneumatic electric valves with electronic control. The whole system is controlled by computer, ensuring adjustment of different separate functions without machine stopping.

Bottles extrusion. The blown bottles are taken out from moulds and transferred onto unloading guides. The bottles are either unloaded in bulk onto the conveyer belt or lined up for their following transfer to a bottling line by air conveyers.

Working process control. The electronic panel by means of the PLC controls all the machines actions, submit data to an operator and makes diagnostics. A specialized computer for machine control watches its functioning, regulating automatically all functional parameters. There is a possibility to change all the parameters of the working process by means of a computer without mechanical units regulation, because all synchronic interactions are controlled by the machine’s PLC.
