✅ Enhances pouch appearance
✅ Reduces mechanical tolerance errors
CCD Vision Servo Film Deviation Correcting System
A CCD vision system combined with servo correction is used for automatic film alignment.
• Real‑time detection of film deviation
• Closed‑loop servo correction
• Reduced material waste
This system is especially important for printed film with registration marks.
Rapid Edge Sealing Specification Conversion Module
The HMK series includes a positioning module for fast conversion of edge sealing specifications.
✅ Shorter changeover time
✅ Reduced setup complexity
✅ Improved production flexibility
This is ideal for factories producing multiple pouch formats.
Servo Seal Position Adjustment (FE Model Optional)
For FE models, a servo seal position adjustment module allows precise control of bag length.
• No mechanical adjustment required
• High repeatability
• Suitable for frequent size changes
Servo Bag Width Adjustment Module (FE Model Optional)
Bag width adjustment in FE models is also servo‑controlled.
This design: ✅ Eliminates manual fine‑tuning
✅ Improves dimensional consistency
✅ Reduces operator dependency
Automatic Lubrication System
En automatic lubrication system is integrated to ensure smooth mechanical operation.
• Reduces wear of moving components
• Extends equipment service life
• Minimizes maintenance workload
Cooling Device for Strengthened Top Seal
A dedicated cooling device is used to stabilize the top sealing area.
This improves: ✅ Seal strength
✅ Pouch appearance
✅ Packaging reliability
Pouch Conveyor Module with Maglev Guideway
The pouch conveyor uses a maglev guideway structure, enabling:
• Smooth pouch transfer
• Reduced vibration
• Higher output stability at high speed
Production Management System (HMI) and IIoT Integration (Optional)
The HMK series can be equipped with a Production Management System (PMS) integrated with HMI and Industrial Internet of Things (IIoT).
Functions include: ✅ Online production monitoring
✅ Real‑time performance data
✅ Equipment status management
This option is suitable for smart factory environments.
Full Servo Configuration for FE Series
En FE series is available in a full servo version, providing:
• Higher precision
• Faster response
• Better synchronization
This configuration is recommended for high‑end packaging applications.
