The structural principle of automatic filling and sealing machine
Date: 2025-05-13Read: 3
The structural principle of the automatic filling and sealing machine can be divided into two parts: mechanical structure and workflow:
1、 Mechanical structure
1. Transmission system
Adopting a fully enclosed transmission design, precise container rotation is achieved through indexing discs or rotary molds.
Equipped with a frequency conversion speed control device, it can flexibly adjust the production speed.
2. Supply and positioning system
Automatically transport hoses to workstations through pneumatic or mechanical buffering feeding devices.
Using photoelectric sensors (electric eyes) to achieve color or center positioning, ensuring the accuracy of filling alignment.
3. Filling system
Adopting servo adjustment system or metering pump to control the filling volume, supporting direct adjustment of parameters through touch screen.
The filling head is inserted into the bottom of the tube to follow the feeding process, reducing air residue inside the tube and lowering the risk of oxidation.
4. Tail sealing device
Equipped with a three-layer inner wall heater and outer wall cooling system (such as cold water circulation) to achieve rapid hot melt pressing.
Supports multiple tail sealing forms (double folded, triple folded, saddle shaped, etc.), and completes irregular tail sealing through quick change jaws.
5. Control system
Based on PLC program control, integrate human-machine interface (HMI) to achieve parameter setting and real-time monitoring.
Automated completion of the entire process including supply management, cleaning, filling, sealing, and coding.
6. Material and Safety Design
The material contact part is made of 316L stainless steel, which meets GMP hygiene standards.
Equipped with safety interlock devices (such as door opening and shutdown, no filling without pipes, overload protection).
2、 Workflow
1. Container transportation
Manually or automatically place the hose into the tube box, and the mechanical device transfers it to the filling station through a dividing disc or conveyor belt.
2. Cleaning and positioning
Compressed air is used to clean the inner wall of the hose, and a photoelectric sensor is used to detect the color code and correct the positioning.
3. Precise filling
Insert the filling head into the bottom of the tube, follow the feeding process and eliminate air to ensure stable filling volume.
4. Hot melt sealing tail
By instantly heating and softening the inner wall of the tail of the pipe, combined with external cold pressing forming technology, the pipe mouth is sealed.
5. Coding and Production
After sealing, the batch number or date will be automatically printed, and the finished product will be discharged through a chute or conveyor belt.
3、 Core advantages
Intelligence: Supports touch screen parameter adjustment, fault self checking, and production data statistics.
Compatibility: Modular design enables quick changeover and adapts to the production of multiple specifications of hoses.
Stability: The combination of mechanical linkage and pneumatic control ensures the reliability and continuity of actions.
