The 12,000BPH PET bottle hot filling machine is a bottle washing, filling and capping machine designed and manufactured by our company. The equipment has stable performance, advanced technology, beautiful appearance and complete functions.
This machine is mainly used for hot filling of various energy drinks such as fruit juice and tea drinks. Only a few parts need to be replaced, and it can be applied to the filling of pure water and mineral water.
1. Technical structure characteristics:
1) Bottle washing part:
This machine is a rotary bottle washing machine, mainly used for washing new bottles of beverages, water and other products. Then the bottle is sent to the filling machine for product filling.
The PET bottle enters the equipment from the bottle separating star wheel, and the bottle mouth is clamped by the clamp and the turning mechanism, and the bottle mouth is turned down. The sterile water is rinsed and drained. Installed. The main structure of the equipment is in contact with the flushing medium and the external protective cover is made of high-quality stainless steel; open gear transmission.
The new stainless steel clamp has simple structure and convenient adjustment; the contact area with the bottle mouth is small, effectively avoiding secondary pollution to the bottle mouth.
The water inlet pipe of the bottle washer is equipped with a pressure gauge.
The bottle washer is equipped with a drip tray to recover the bottled water.
When flushing the bottle, the flushing volume of each bottle is: 105ml/s (at 0.25MPa).
2) Filling part:
The filling part realizes the filling of materials into the washed bottles sent by the bottle washing machine.
The filling machine is self-designed by our company, and the filling valve has independent intellectual property rights. It uses the filling principle of pressure filling and negative pressure backflow.
The filling valve adopts the pressure filling negative pressure type backflow method, the filling is quick and sensitive, and the filling level is high in accuracy. There is no spring in the valve, and the material does not contact with the spring, which facilitates the cleaning of the inside of the valve. Ensure the filling process and filling temperature requirements. The material in the filling valve is in a slight reflux state when there is no bottle or when it is shut down.
Add opening and closing devices before the filling valve to realize open valve filling, and close the valve after filling, which can accurately control the filling level and prevent the filling valve spraying material from polluting the bottle mouth; and can effectively control the material return flow ≤ 5～8%;
The filling cylinder adopts the full cylinder method to ensure the stable pressure in the cylinder.
The whole machine has a complete CIP cleaning structure.
The double guide rod bottle lifting structure is adopted to make the bottle lifting and centering stable.
The main drive adopts gear drive that is open type combined drive, which has high efficiency, low noise, long life, convenient maintenance and sufficient lubrication. The frequency converter is used to control the speed of the main motor of the machine. This machine adopts stepless frequency conversion speed regulation.
The bottle guide system has a simple structure and can be quickly and easily changed according to the bottle type. The whole machine adopts a bottleneck structure for transportation.
The whole machine is automatically controlled by PLC, and faults are displayed online, such as bottle blocking, missing cover, etc.
The key parts and electrical components of this machine are imported products.
3) Screw cap part:
The capping part will screw the cap arranged by the capping device to the bottle of the filled product, and send it to the subsequent process by the conveyor chain.
The capping machine drives the turntable to rotate through the reducer. The cover leaves the hopper from the cover outlet under the action of centrifugal force. There is a front and back cover separating device at the exit. When the back cover passes by, the cover automatically falls into the return pipe, and the back cover is automatically blown into the hopper by wind. Only the front cover can enter the chute smoothly. The amount of cover in the hopper is automatically detected by the photoelectric switch to control the cover conveyor to ensure the best effect of the lower cover. When the front cover enters the slideway, you can enter the cover feeding tray smoothly. In order to prevent accidents, an anti-reverse cover dial is also configured on the slideway to ensure that the cover that enters the feeding cover tray is correct. A pair of slides are also provided Photoelectric switch, when detecting that there is no cover, it will stop the host immediately. In order to effectively remove the broken cover without the anti-theft ring and clean the remaining cover of the hopper, there is a movable outlet directly opposite the hopper outlet to meet this function.
The screw cap is a magnetic screw cap, with overload protection function, and the screw cap torque is stable and reliable. The sealing has no gnawing, high, crooked, and curling.
This machine adopts a centralized lubrication system to conveniently lubricate each lubrication point.

二. Main structure and characteristics
1. Frame: 100×100mm high-quality carbon structural steel welded frame, outer cover 304 stainless steel protective layer, waterproof treatment, free to wash above the table.
2. Outer seal: 10mm high-strength tempered glass protective cover, good light transmission, easy to observe the operation of the equipment, stylish and beautiful.
3. Transmission part: Metal gears are used to mesh with MC nylon gears, which greatly reduces noise and smooth transmission.
4. Bottle transfer: All dials and guide plates of this machine are made of ultra-high polymer material, which is sturdy and durable, effectively preventing glass scratches. The bottom of the bottle holder is 304 stainless steel, which greatly reduces the wear rate.
5. Bottle rinsing part: the bottle rinsing pump is resistant to high temperature; the nozzle adopts imported solid cone nozzles, the spray angle is 15°, and there is no dead angle in the rinsing; the rinsing time>2s, the draining time>1.5s, that is to ensure the thorough flushing Ensure that the residual amount in the bottle meets the standard.
6. Filling part: CIP cleanable; equipped with automatic switching valve and temperature sensor, the material temperature is low without filling, and it will automatically switch to the reflux tank; the material temperature is high and alarm.
7. Sealing part: The combination of pre-rubbing cap and screw cap is adopted to greatly improve the qualification rate of the seal; the tensioning belt prevents the bottle from slipping.
