Rotary stretch blow molding machine is a modern high-tech equipment integrating machine-electric-liquid-gas four-in-one. The high-speed and high-efficiency molding advantage has become the development direction of stretch blow molding machine. Its market has been monopolized by French SIDEL company. There is no high-speed, high-efficiency, multi-functional, industrialized rotary stretch blow molding machine, and the development of a rotary stretch blow molding machine can enhance its competitiveness in the market.
Process innovation
Preform feed. The preform is poured into the storage hopper, and the conveyor automatically lifts the preform to the blank, after which the preform is neatly arranged on the guide rail, and the preform is automatically fed into the apparatus by gravity. Automatic control of the blank, high efficiency of the blank without damaging the preform.
The preform is heated. The preform is automatically and continuously obtained at the heating head of the incoming star wheel, and the preform rotating at a constant speed is continuously subjected to a special heating zone to obtain precise control heating, and the temperature distribution is uniform and reasonable.
Stretch the blow bottle. The cam mechanism accurately controls the opening and closing of the mold. The simple mold base mechanism makes the replacement of the mold more convenient and quick. The special mode-locking press system makes the clamping mode fast and stable. The special structure of the mouthpiece, the original blowing control technology, improves the yield.
Mold out the bottle. The robot automatically takes the bottle out of the mold and receives the quality test. The bottle that meets the quality requirements is transported to the belt and removed for storage in the bottle compartment or online.
Institutional innovation
Preform conveying mechanism: a unique preform mandrel conveying mechanism that ensures the risk of the preform not being reversed when heated.
High-speed operation of the clamping mechanism: the patented circular arc-type clamping structure of the independent intellectual property rights, the special mode-locking supercharging system, high-speed operation and stable noise-free.
Hot-fill bottle forming mechanism: When blowing hot-filled bottles, the three-way circulating special design dispenser is used to evenly distribute the different required water/oil temperatures to different parts of the mold to achieve the best crystallinity of the bottle.
Lightweight energy-saving blow molding system: The combination of cold air and hot air is used to forcibly cool the bottle mouth and the drive shaft during heating to achieve the best cooling method. The air guiding device is adopted in the heating box to overcome the air convection, ensure the balance of the heating temperature of the preform, and prevent the surface of the preform from overheating.
Energy-saving sealing machine blowing air combination valve: the valveless connection of the valve, compact structure, simple commissioning and maintenance, reasonable consumption of high and low pressure gas, to achieve the best energy consumption control.
Simple and reliable manipulator: The cam link type of the blank and the robot for taking the bottle are simple, excellent in coordination and low in manufacturing cost.
Clean and safe molding design: The equipment adopts a fully enclosed structure to ensure a clean molding environment, which eliminates the pollution of the molded bottle and ensures the cleanliness of the medical infusion bottle. The perfect and reliable safety door system ensures the safety of the operators and the long-term stability of the equipment.
Control innovation
Preform heating system
Infrared heating controlled by thyristor, each layer of infrared tubes can be independently controlled. The air flow in the heating zone and the unique design of the bottleneck protection device enable the preform to obtain the ideal temperature curve. At the same time, the bottleneck is not affected by the heating, and the infrared thermometer is used to realize the automatic temperature regulation to realize the intelligent heating control of the preform. The heating tube enables individual adjustment control.
operating system
The man-machine dialogue operating system intuitively reflects the production status. The heating temperature of the preforms is displayed through the touch screen operation. The control parameters can be adjusted according to the requirements of the blowing process, and the blowing parameters of each cavity can be conveniently controlled through the touch screen.
Security system
The mechanical interlocking protection of the clamping machine avoids damage to the equipment when the mold clamping is not smooth. The mechanical interlocking protection of the clamping machine ensures the safety of the mold and the formwork. The double limit detection of the bottom mold and the open mold ensures that the bottom mold is not lost during high-speed operation. The sealing multi-point detection device protects the safe operation of the robot and the stretching rod to the utmost. Bottle taking inspection ensures safe operation of the blank manipulator and mold. The electronic detection system automatically removes the unformed bottles and defective preforms without any risk, preventing the risk of downtime. Heated lamp disconnection alarm detection.
Processing capacity
The forming speed of the stretch blow molding machine is the primary parameter of the processing ability, and is the main goal pursued by the stretch blow molding equipment. The ECOBLO® Rotary Stretch Blow Molding Machine optimizes the heating system to reduce heating time, increase the running speed of the preform, increase the stability and stability of the preform, shorten the opening and closing of the mold and the lifting time of the blow molding head, and increase The number of molding cavities increases the single-mode output and total output. The capacity of 1,700 units per hour has reached the international advanced level.
Multi-functional molding innovation
Ordinary rotary stretch blow molding machines can only form cold-filled PET containers with a single function and a narrow surface. The technology of forming a PP bottle by a linear stretch blow molding machine independently developed by Jiahong Company, combined with the characteristics of a rotary stretch blow molding machine, developed the technical equipment for forming a PP bottle by a rotary stretch blow molding machine, which is a PP material. The medical infusion bottle and the rinse bottle are provided with high-tech equipment, which is not only suitable for stretch blow molding of PET bottles, but also suitable for stretch blow molding of PP bottles. Jiahong also independently developed an oil/water three-way distributor suitable for stretch blow molding hot-fill bottles, hot-filling blow molding dies and hot-mould blowing stations, so that users can quickly replace the relevant devices. Stretch blow molding of hot-filled bottles to achieve multi-purpose multi-function.
The ECOBLO® Rotary Stretch Blow Molding Machine has been successfully applied to famous companies such as Canadian CCC, China's Polar Bear and Watson for stretch blow molding containers at home and abroad. The ECOBLO® Rotary Stretch Blow Molding Machine is proven to be fast, efficient, stable, safe and reliable.
