1.1 Product Description
The BY-XGF-8-8-3 type PET bottle washing/filling/capping three-in-one machine is an advanced model independently developed by our company based on the latest international filling technology and processes. It is specifically designed for the filling of still beverages such as mineral water and purified water. This machine uses a neck-bottle positioning conveying method, and only requires a few changes in components to be suitable for various bottle sizes, minimizing bottle body wear and ensuring smooth conveying. The filling method is micro-negative pressure gravity filling, which increases the filling speed and precisely controls the liquid level. The sanitary-grade circulating pipeline provides a reliable guarantee for product quality. The immediate grab and cap technology imported from France is at the leading level in China.
1.2 Main Structural Features:
● Frame
The frame is made of structural steel with a 304 stainless steel outer layer, 304 stainless steel frame, and adjustable stainless steel feet.
● Conveying System
The bottle conveying system uses neck-bottle positioning control throughout the process except for the bottle exit star wheel. All star wheels are 304 stainless steel neck-bottle positioning star wheels. Empty bottles are conveyed to the bottle entry star wheel by a pneumatic conveying system.
The bottle exit pusher wheel adopts a non-neck-bottle positioning structure, which avoids the need to adjust the height of the chain conveyor surface of the equipment after the three-in-one machine when adjusting the bottle height.
When users change bottle shapes with different diameters or heights, they only need to replace the positioning pusher wheel blocks, which is convenient and fast.
The pneumatic conveying system is used to convey bottles to the bottle entry star wheel, ensuring the reliability of bottle operation.
● Rotating Bottle Washing Section
There are 8 bottle clamps in the bottle washing section, using a snap-in type stainless steel bottle clamp. The clamps do not touch the part above the bottle mouth thread. The bottle washing nozzles are solid cone-shaped nozzles that can reach every corner of the bottle wall and bottom, ensuring thorough cleaning.

● Rotary filling section
There are 8 filling valves, and all parts in contact with the beverage are made of 304 stainless steel. The inner surface of the filling cylinder is mirror-polished. The high-speed, high-flow and high-precision filling valves ensure fast filling speed and accurate liquid level.

● Rotating Capping Section
The capping head quantity is 3. The capping machine adopts the technology of French AROL Company. The capping is magnetic capping with overload protection function, and the capping torque is stable and reliable. There is no phenomenon of biting the cap, high cap, crooked cap or curled edge during capping.
The lower cap slide is made of 304 stainless steel. A photoelectric switch is installed on the lower cap slide to automatically control the start and stop of the cap aligner. It can realize the function of no cap sent without bottle and automatic stop when there is no cap in the lower cap slide.
A cap measuring device is installed in the cap aligner. When combined with the cap feeder, it can realize automatic cap feeding.
