In depth analysis of the intelligent control system of the automatic filling and sealing machine
Date: 2025-08-12Read: 6
The intelligent control system of the automatic filling and sealing machine is the core of its efficient operation. The following is an in-depth analysis of it:
1、 Composition of control system
1. Human machine interface: Adopting a large touch screen display/operation control panel, operators can directly perform temperature setting, motor speed adjustment, production speed adjustment and other operations on the screen, which is intuitive and convenient, realizing contactless operation and reliable operation.
2. PLC control: PLC is the core of the entire control system, responsible for signal and data processing. It has powerful logical and data processing capabilities, which can accurately control parameters such as filling volume, sealing temperature, printing batch number, etc., ensuring the stability and accuracy of equipment operation.
3. Sensor system: Using photoelectric sensors to achieve automatic positioning, such as in the pipe supply process, automatic calibration is achieved through photoelectric induction. In the filling process, whether to start the filling action is determined by detecting whether there are pipes on the workstation, ensuring the accuracy of filling and sealing.
4. Temperature control system: an intelligent temperature control and cooling system that precisely controls the temperature of the tail heating section. For example, using DELTA's DTC to control the temperature of the sealing heating head, ensuring that the sealing temperature is appropriate and avoiding unstable sealing or damage to the product appearance due to high or low temperature.
5. Variable frequency speed regulation system: The host adopts variable frequency control, and users can freely adjust the operating speed of the whole machine according to the requirements of the supporting machine, achieving stepless variable frequency speed regulation and improving production efficiency.
2、 Control system functions
1. Automated operation: It can achieve the full process automation from pipe supply, washing, labeling, filling, sealing to coding, trimming, and finished product production. For example, the automatic tube feeding device automatically inserts the flexible tubes into the positioning mold after arranging them in a row. The filling head detects the plastic tube and automatically inserts it into the tube, followed by material injection. After completing the filling, it automatically seals the tail and codes, and finally the finished product automatically exits.
2. Parameter adjustment and memory: Supports one click parameter switching, compatible with different viscosity materials and packaging requirements, without the need for frequent equipment debugging. At the same time, there are quantity memory and quantitative shutdown devices, which facilitate parameter adjustment and equipment maintenance during the production process.
3. Safety protection: equipped with safety devices such as door opening and shutdown, no filling without pipes, overload protection, etc., to ensure the safety of operators and the stable operation of equipment.
4. Fault diagnosis and display: Equipped with fault display function, it can timely detect and prompt abnormal situations during equipment operation, facilitating operators to quickly locate and solve problems.
3、 Advantages of control system
1. Improve production efficiency: With a high degree of automation, it reduces manual intervention and allows for one person operation, greatly improving production efficiency.
2. Ensure product quality: Through precise filling and sealing control, ensure filling accuracy, firm and beautiful sealing, reduce product oxidation, and improve product quality.
3. Reduce labor intensity: Easy to operate, convenient to adjust and disassemble, reduces the labor intensity of operators, and at the same time reduces production errors caused by human factors.
4. Strong adaptability: It can adapt to various industries and different specifications of hoses. When changing products, only one part needs to be adjusted to avoid the trouble of product replacement. It has strong universality and flexibility.
