Digesting and absorbing advanced foreign technology, the automatic rotary blowing molding machine of Newamstar is specially researched and developed aims at catering to the high speed and high output trend of blowing machine. The machine is used for producing PET bottle (water, carbonated soft drink, hot filling drink), with reasonable structure, compact flour space, low energy cost and stable operation. The rotary blowing machine is accord with national food hygienic standards, proved to be the preferable machine for different manufacturers.

1. Main Characteristics

1)        The operation order is manipulated on HD TFT touch screen with different interface languages, orders are shown by means of integrating pictures and texts on the screen with multilevel menu options. Capacity, counting, parameter setting options are all displayed on different level menus of the screen, easy for operation with the human – computer interface.

2)        High capacity, single mold: water bottle (5L) 6,000BPH

3)        Specially designed secondary blowing system. The changing curve of pressure in each mold during the formation of bottle can be monitored in time, providing timely parameter for corresponding adjustment. As a result, operator of the machine can adjust the parameter setting conveniently and insure the quality of bottle.

4)        Cam mechanism is used to precisely control the transferring procedure of manipulator. Inlet and outlet of preform and bottle are all conducted through the manipulator accompanying the opening and closing of the mold, with efficient and accurate movement. All movements are completed automatically by manipulator, which avoids the intermediate pollution.

5)        Opening and closing of mold are conducted under the function of cam mechanism, with a specially designed mold locking pressurization system and a firm mold structure. The blowing parameter setting can be done separately for each mold. Structure of the blowing mold ensures the reliability of sealing in different pressure situation. The pressure of blowing can be adjusted accordingly with the good diagnosing function. Stretching rod controls axial tension in the preform accurately, first and second blowing controls the longitudinal tension. The desired spreading of thickness of the bottle can be achieved precisely by controlling the first and second blowing.

6)        Breaking the traditional design.It uses coaxial rotary sleeve pipe with small cubage and light weight, and two deep groove ball bearings to fix the two ends, to make the outer sleeve, mandril be concentric and ensure the rotary sealing ring is not easy to be damaged. Simultaneous adding one water back path to make the leaked water in GlydRing refluence along the pipe to ensure water distributor not leak.

7)        10 lines infrared heating control system is used in the heating oven. Temperature of heating tube can be adjusted according to the technical requirement in pre – heat and adjusting area respectively, with real time inspection system equipped. Therefore, accuracy and stability of the working efficiency can be achieved, whilst, averting excessive heat on the outer wall of the preform. The economic effect of machineries in Newamstar is obvious that 10% - 20% energy can be saved in the heating process compared with its counterparts.

8)        Air recovery system can be installed in pneumatic parts of the machine (as customer required), compressed air consumption is 30%-50% less than machine without air recovery system, as a result, energy consumption and cost can be reduced.

9)        Technical parameters like heating temperature and blowing time can be adjusted accordingly in line with different preforms and bottle sizes. The production can be continued directly only with pressing the button to launch the pre-setting parameter when changing the preform and bottle.

10)     Using imported lubrication system from Germany. Lubricating the machine automatically, maintaining the machine thoroughly and reducing worker’s workload.

11)     Mold installation is convenient, which can be done within 1 hour. Therefore, shut down period can be shortened and production efficiency can be improved.

12)     Humanized design makes the complicated industrial control easy for people to operate a possible. High definition HMI and multi – language option are suitable for people in different countries.

13)     Equipped with real – time monitoring function and various trouble alarming system which can provide notice and help. The flexible setting of parameter can satisfy different technical requirements of the production.

14)     Superior hardware and network, matured technics, creative design, perfect control, which all makes the quality guarantee a possible.

15)     According to client’s requirement, the whole system can be maintained through Ethernet.

16)     Specialized alloy aluminum is adopted in making blowing mold. The surface of the mold is treated with special oxidation treatment, make the mold life as longer as possible and reduce the production cost.

17)     Preform stuck detecting device is equipped on the star wheel (preform inlet drive plate), preform will be kick off when blocked. The device will be reset automatically as abnormal preform is kicked.

18)     For security reason, the machine is equipped with reliable safe door system and alarming device. Therefore, operator’s security can be guaranteed furthest.

1. Main Configuration

1)        Main configuration (components) is global brand products, so as to ensure the advancement and stability of the machine.

2)        The machine is made of aluminium alloy, mild steel, stainless steel and alloy steel.

3)        The bearing is procured from China’s superior supplier, imported bearing (producer: Japanese and German). Oil – less bearing with self-lubricating grease, IGUS self – lubricating bearing.

4)        High pressure valve is procured from NORGREN, EUGEN SEITZ (Swiss), SMC (Japan) etc.

5)        High pressure exhaust muffler is procured from the USA, Germany etc.

6)        Pneumatic system is procured from FESTO (Germany), SMC (Japan), NORGREN etc.

7)        Touch screen is procured from Schneider (Germany) etc.

8)        Electrical apparatus control system (PLC) is procured from MITSUBISHI (Japan), SIEMENS (Germany), Schneider etc.

9)        Photoelectric sensor is procured from TURCK (Germany), OMRON (Japan) and BANNER (USA) etc.

10)     Approaching switch is procured from SIEMENS (Germany), Schneider etc.

11)     Amphenol connector is procured from PHOENIX (USA), ABB etc.
