Pre-made Pouch Packing Machine
The pre-made pouch packing machine is an advanced automatic packaging device specially engineered for filling and sealing pre-made pouches, compatible with stand-up pouches, flat pouches and other pouch styles. It directly adopts finished bags, which greatly cuts production time and avoids various malfunctions generated during in-line bag making.Guangdong Yiren Technology independently develops the rotary pre-made pouch packing machine. It integrates multiple stations including bag feeding, bag opening, filling and sealing to deliver continuous, high-speed integrated operation. This equipment is widely used in food and other industries.
Pre-made Pouch Packing Machine Core Technical Advantages
1. Servo-Driven Motion Control System
Equipped with an AC servo motor main driving system, the machine achieves higher positioning accuracy than traditional pneumatic and mechanical transmission structures. The servo system supports the following functions:
– Precise pouch positioning & clamping: Grips and aligns pouches with micron-level precision
– Production parameter storage: Saves fixture specifications, machine speed, sealing temperature and filling volume for quick product changeover
– One-click formula recall: Saved formulas can be restored with one tap to recover all parameters even after misoperation
2. Intelligent PLC Control System with Touchscreen HMI
Fitted with high-end PLC and user-friendly touchscreen Human-Machine Interface (HMI), the machine allows operators to monitor and adjust the whole packaging process in real time. Built-in PLC functions:
– Independent temperature control modules for each sealing station
– Bag presence sensor: Automatically halts filling and sealing when no pouch is detected to eliminate idle cycles
– Built-in production data logging for output statistics and quality control
3. High-Precision Sealing System with Independent Temperature Control
Sealing performance is the core standard of pouch packaging. This machine is equipped with a dedicated sealing unit:
– Independent adjustable temperature control system
– Two-stage sealing process delivers flat, airtight seals to prevent material leakage and contamination
– Adjustable sealing parameters: Temperature, pressure and holding time can be fine-tuned on the touchscreen based on bag materials
– LDPE pouches: 120–150°C
– Polyester aluminum foil composite pouches: 160–200°C
– Ordinary composite pouches: 100–160°C
– Cooling station: Instant cooling and shaping after heat sealing to avoid seal deformation
4. Heavy-Duty Frame & Modular Design
– Integrated thick welded steel frame for stable structure and excellent vibration resistance
– Compact footprint to maximize workshop space utilization
– Fast changeover design: Servo adjustment structure drastically reduces downtime for product switching

Common Technical Faults & Professional Troubleshooting
Even top-stable packaging equipment may encounter operational failures during running. Below are frequent faults of pre-made pouch packing machines and corresponding solutions, summarized from years of manufacturing and after-sales maintenance experience of Guangdong Yiren Technology.
Fault 1: Uneven & Weak Seals
Symptoms：Bags split easily, wrinkled seals, material leakage during storage
Root Causes
1. Improper sealing temperature (low temperature causes weak sealing; excessive temperature burns film)
2. Dust or liquid residue accumulated on sealing blades
3. Uneven pressure along the full length of sealing blades
4. Incorrect trimming parameters leading to poor edge finishing
Solutions
1. Adjust matched sealing temperature on the touchscreen according to pouch material
2. Wipe sealing blades with soft cloth to remove material residues
3. Calibrate sealing pressure on both sides to ensure uniform stress
4. Modify trimming parameters
Fault 2: Failed Bag Feeding & Pouch Pickup
Symptoms: Machine cannot grab pouches from the hopper; pouches shift out of position or fall midway
Root Causes
1. Insufficient vacuum negative pressure
2. Aged or dirty suction cups
3. Uneven pouch thickness or static electricity on bags
4. Misaligned bag detection sensor
Solutions
1. Check vacuum pressure gauge and adjust pressure to standard range
2. Clean or replace suction cups regularly
3. Standardize pouch placement and adjust guide rails to match pouch width
4. Recalibrate the position of bag presence detection sensor
Fault 3: Pouch Leakage After Sealing
Symptoms: Sealed bags leak during storage and transportation with failed tightness
Root Causes
1. Mismatched sealing temperature for pouch material
2. Worn or misaligned sealing blades
3. Powder, liquid or foreign debris on sealing area
4. Damaged pouches with pinholes before filling
Solutions
1. Calibrate sealing temperature by pouch material (LDPE: 120–150°C; Polyester aluminum foil: 160–200°C)
2. Inspect sealing blades for scratches and wear, recalibrate mounting position
3. Keep sealing contact surface clean without impurities
4. Conduct appearance inspection of pouches before warehouse incoming
Fault 4: Unexpected Shutdown & Sudden Speed Drop
Symptoms: Intermittent machine shutdown; actual speed lower than set value
Root Causes
1. Insufficient compressed air supply pressure
2. Emergency stop button pressed or safety guard door unclosed
3. Abnormal tension of conveyor belt
4. Lack of lubrication on moving components
Solutions
1. Confirm air supply pressure stays within standard range
2. Inspect all safety interlock devices and emergency stop switches
3. Adjust tightness of conveyor belt
4. Establish regular lubrication maintenance schedule for all moving parts
