This type machines ensure: Possibility of the following container types production:
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. 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. All the unit’s functions, production parameters, time of partial and full cycles are controlled by the Programmable Logical Controller (PLC) equipped with a "touch-screen" monitor, which greatly facilitates the machine control. Temperature and pressure values are controlled by the special feedback system, which guarantees invariability of the process parameters. The machine is equipped with an autodiagnostic programme with summary-analytical tables and exact instructions in case of any malfunction or deviation from the process parameters.
We supply both separate machines for blown goods production and “turn-key” plants including main and auxiliary equipment for raw material preparation, manufacture and package of finished products. Supply includes compressor and refrigerating equipment and transport units.
