Core Components and Three Major System Safeguards (LANTU Precision Components)

Our Horizontal Pouch-Feeding Packaging System is equipped with top-tier industry core components across the entire line, guaranteeing high quality, flawlessness, and an ultra-long service life from the source.

1.Horizontal Pouch Feeding, Picking, and Opening System

Horizontal Large-Capacity Flat-Shift Feeding Mechanism: Uses a horizontal storage magazine that supports loading large quantities of pre-made pouches at once, making replenishment more convenient. Paired with imported SMC vacuum generators and wear-resistant silicone suction cups, it ensures stable horizontal shift gripping without double-bag intake.

Dual-Axis Pneumatic Opening and Air Inflation Expansion: Features synchronized upper and lower vacuum suction cups to pull open the bag mouth, combined with high-pressure air injection nozzles and zipper-opening devices to guarantee 100% successful opening for zipped or rigid pre-made stand-up pouches.

One-Touch Electric/Automatic Gripper Width Adjustment: When changing pouch specifications, simply input the width on the touchscreen. The system automatically drives all grippers across the line to adjust into position within 3 minutes.

2.Filling, Settling, and Dual Heat-Sealing System

No-Pouch / Unopened-Pouch No-Fill Protection: An intelligent sensing system detects the bag opening status in real time. If a pouch fails to open, filling and sealing are bypassed, allowing the pouch to be reused and completely preventing material waste and equipment contamination.

Base Tapping/Settling and Pouch-Stretching Mechanism: The filling station is equipped with pneumatic tapping and base-vibration devices to quickly settle bulky or chunk material to the bottom. Alignment-stretching grippers are used before sealing to ensure smooth, wrinkle-free seals.

Dual Heat Sealing and Cold-Press Shaping: Employs first-stage high-pressure heat sealing + second-stage smooth heat sealing/embossing + third-stage cold-air flattening/shaping. The seal is aesthetically pleasing, firm, and highly resistant to bursting and leakage.

3.Intelligent Control and Safety Protection System

Siemens/Mitsubishi PLC Central Control Core: Industrial-grade multi-core CPU control delivers stable operation, strong anti-interference capabilities, and supports switching between 10 languages.

Seamless Multi-Head Feeder Interlocking Interface: Features standardized interlocking communication protocols to seamlessly interface with 10/14-head multi-head weighers, auger fillers, liquid/paste dosing pumps, and tablet/counting discs.

Fully Enclosed Safety Protection Door: The thickened 304 stainless steel body is fitted with transparent safety doors that pause operation when opened. This complies with GMP and food/pharmaceutical hygiene standards while maximizing operator safety.

Technical Specifications

To meet the diverse demands of factories regarding pre-made pouch dimensions, large-capacity heavy bags, and spout pouches, Lanto Machinery offers two core models of Automatic Horizontal Premade Pouch Packaging Systems:

Complete Horizontal Pouch-Feeding Workflow Breakdown

Station 1 (Horizontal Feeding/Picking): The horizontal storage magazine smoothly advances the pouches; vacuum suction cups horizontally grip and feed the pouch into the conveyor grippers.

Station 2 (Date Printing/Coding): Optional ribbon coders, inkjet printers, or Thermal Transfer Overprinters (TTO) precisely print production dates and batch numbers on designated areas of the pouch.

Station 3 (Opening/Zipper Opening): Upper and lower vacuum suction cups pull open the bag mouth; air nozzles insert to blow open the pouch bottom. If zippers are present, zipper teeth are unzipped simultaneously.

Station 4 (Filling/Dosing): The feeding equipment (multi-head weighers/auger/liquid pump) receives a signal and dispenses material precisely; the filling nozzle features anti-drip and anti-jamming devices.

Station 5 (Settling/Pouch Stretching): Bottom settling devices tap the pouch base to settle material, leaving ample clearance for sealing; secondary filling can also be performed here.

Station 6 (Nitrogen Flushing/Reserved): Optional nitrogen flushing devices evacuate air from the pouch for freshness preservation, or serve as a third filling/liquid injection station.

Station 7 (Heat Sealing): PID intelligent temperature-controlled heat-sealing jaws close under high pressure to complete aesthetically pleasing bag mouth sealing.

Station 8 (Cooling Shaping & Output): Cooling blocks quickly flatten the seal, and finished pouches are smoothly output by the conveyor belt.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of a Horizontal Pouch-Feeding System compared to a Rotary Pouch-Feeding Machine?

A: The horizontal system uses a flat-shift structure. Its horizontal pouch magazine can hold significantly more pre-made pouches at once, allowing replenishment without frequent stops. It performs exceptionally well regarding conveyance stability for large-capacity, heavy-duty, or spout pouches, while providing more spacious room for maintenance and inspection.

Q2: If the pre-made bag fails to open, will the material spill out and contaminate the machine?

A: Absolutely not. We equip the machine with no-bag / unopened-bag detection sensors. As long as a pouch is unopened, the system automatically skips dispensing and sealing. Material remains safely in the hopper, and the pouch advances to the next cycle or triggers a stop prompt.

Q3: Is it complicated to adjust the grippers when switching to different pouch sizes?

A: It is extremely simple. The entire machine features electric one-touch width adjustment. Input the target pouch width on the PLC touchscreen, and all mechanical grippers across the line will automatically adjust in sync within a few minutes.
