How the Fully Auto Empty Bottle Packing Machine Works ！

A fully auto empty bottle packing machine is a sophisticated piece of equipment designed to automate the process of packing empty bottles (such as plastic bottles, glass bottles, or PET bottles) into containers like cartons, cases, or shrink-wrap sleeves. Its operation involves a series of coordinated steps to ensure efficiency, accuracy, and consistency. Below is a detailed breakdown of how it works:
 

1. Bottle Feeding
 

Conveying bottles into the packaging machine. The system employs a POM wide-mesh conveyor belt with guardrails made of high-molecular PE material, ensuring no scratches on bottles during transportation. The entire line utilizes servo reduction motors, allowing conveyor speed adjustment based on production capacity. Transition between lines is achieved through customized sheet metal connectors or clamping conveyors to ensure smooth product transfer. An inverted bottle detection and rejection mechanism is installed before bottles enter the packaging machine to prevent blockages without affecting overall line productivity.
 

2. Bottle Pushing
 

The bottle-pushing mechanism transfers bottles from the conveyor belt to the 304 stainless steel buffer platform of the packaging machine. The pushing speed of this mechanism is stable and controllable, effectively preventing bottles from tipping over inside the packaging machine. The stainless steel buffer platform prevents scuffing on bottle bottoms during movement. The pushing width of the mechanism can be adjusted according to specific packaging requirements.

3. Bottle Guiding
 

During the pushing process, the mechanism secures the bottles (the lifting cylinder elevates the left and right bottle-guiding sheet metal to the platform level to encircle the bottles) to prevent tipping or disarray during transfer.

4. Bag Pulling
 

The gripper plates on the bag-pulling mechanism clamp the open end of the roll film and draw it to the required packaging length. The film is then severed at its trailing end by a cutting mechanism. A servo motor provides stable power during the process, while a dual-axis cylinder acting on the gripper plates ensures the film does not slip or detach. The roll film is supported by a lightweight air expansion shaft, which is equipped with manual hand cranks on both ends to control inflation and deflation for easy loading of film rolls.

5. Sealing & Cutting

SThis unit performs trailing end sealing and cutting of the roll film. After the bag-pulling process is completed, the lifting cylinder of the sealing and cutting mechanism raises the cutting blade and the film pressing plate until the plate firmly clamps the film. The cylinder responsible for cutting then rapidly extends the blade to sever the film. Following the cut, constant-temperature sealing is initiated to seal the trailing end of the film. The use of constant-temperature sealing ensures high efficiency and results in a smooth, flat seal.

6. Bag Sleeving

The sealed and cut bag is sleeved onto the mechanism and expanded. The bottle-pushing mechanism then pushes the bottles from the buffer platform into the bag smoothly. Both the width and height of the upper and lower bag-sleeving positions can be quickly adjusted via the servo system.

7. Sealing & Finishing the pack

Upon completion of bottle loading into the bag, the front end of the bag is sealed by a constant-temperature system, finalizing the packaging process. The packaged bottles are then pushed out onto the external stainless steel platform of the packaging machine.

7. Automation & Control Systems

A central control panel (PLC – Programmable Logic Controller) coordinates all steps, using sensors and feedback loops to ensure precision;
User Interface: Operators set parameters (e.g., bottle count per pack, packaging type) via a touchscreen;
Sensors & Alarms: Sensors monitor bottle flow, packaging material levels, and machine performance. Alarms trigger for issues like jams, low supplies, or misfeeds, prompting operators to intervene;
Adjustability: The machine can often be reconfigured for different bottle sizes, pack counts, or packaging types.

8. Key Product Features
