Advantages for Servo Control Packaging Machine

The servo packaging machine is a continuous-type packaging machine with exceptionally strong packaging capacity. It is suitable for a wide variety of standards in both food and non-food packaging. Based on the ordinary pillow-type packaging machine, it offers better performance, more complete functions, and easier, safer operation. Let’s now take a detailed look at its advantages:

1. Precision: It realizes closed-loop control of position, speed and torque, eliminating the step-loss problem of stepper motors.
2. Speed: Excellent high-speed performance; the rated speed can generally reach 2,000–3,000 rpm.
3. Adaptability: Strong overload capacity—it can bear a load three times the rated torque, making it ideal for applications with instantaneous load fluctuations or that require fast start-up.
4. Cut-and-reverse: If the blade cuts a product during operation, it immediately reverses, stops, auto-adjusts and then resumes packaging. This raises safety (an operator whose finger is accidentally caught can pull it out), protects products from damage, reduces waste, and allows an N-cut stop setting—safe halting without hurting productivity.
5. No-film stop: A standard feature; when packaging film runs out the machine stops automatically and alarms, saving about 10 min of film-change time each occurrence. With six film rolls used per day, this saves roughly one hour and about 500 m of film daily.
6. Memory function: Stores 100 sets of product parameters; when switching back to a previous product you simply recall the data—no need to re-set.
7. No-eye-mark stop: If the photo-eye fails to detect the registration mark, the machine stops and alarms, preventing miscuts and saving film.
8. Detailed alarms: A tri-color tower light is standard; faults are clearly indicated for quick troubleshooting (on other machines this feature is found only on models costing >100,000 RMB).
9. Unlimited bag-length: Unique to servo machines—bag width is adjustable within a certain range, but bag length can be extended infinitely; products one meter long can be wrapped, a key reason many users choose servo models.
10. Maximum holding torque when the motor is stationary and energized**.
11. Step accuracy of 3–5 % with no cumulative error**, giving good positioning accuracy and motion repeatability.
12. Excellent start/stop and reversing response**.
13. Brushless construction** delivers high reliability; motor life depends only on bearing life.
14. Response determined solely by digital pulses**, permitting open-loop control, simpler construction and lower cost.
15. Direct load coupling to the motor shaft** still allows ultra-low-speed synchronous rotation.
16. Speed is proportional to pulse frequency**, providing a wide speed range.
17. Intelligent, user-friendly parameter design** lets ordinary personnel become proficient in a short time, lowering the skill requirement for operators.
