Automatic packaging machine GQ

PLC-controlledwith shrink tunnelheat-shrink film

Product overview
Pillow packaging machines from the GQ series are industrial packaging units designed for automatic packing of food, pharmaceuticals and daily-use items. They form individual pillow-shaped packages using flexible films or bottom-fed paper, adapting to different production rates and package types.

Available models

• GQX-350 — bottom paper feeding pillow packaging machine
• GQ-350 — high-speed pillow packaging machine
• GQ-450 — high-speed pillow packaging machine
• GQ-590 — automatic heat-shrink packaging machine

Functions / Process Capabilities

• Automatic feeding and conveyance
• Accurate measuring and portioning
• Product filling
• Automatic bag/forming and sealing
• Date and batch printing
• Inflation/exhaust control
• Finished product discharge for downstream handling

Working principle — Bottom-feeding pillow packaging machine

• Paper supply: paper roll is unwound and fed into an unfolding/forming unit.
• Packaging formation: paper is folded into an open tubular structure similar to pillow-film tube.
• Product supply: products are inserted into the tubular structure at set positions.
• Sealing and cutting: forming, sealing and cutting are performed (heat or pressure) to create discrete paper bags.
• Discharge: finished paper bags are discharged for secondary packaging (strapping, boxing, etc.).

Working principle — High-speed pillow packaging machine

• Optimized mechanical structure and control system enable high packaging speeds.
• High-precision positioning ensures accurate sealing and cutting.
• Advanced automation: synchronized feeding, sealing and cutting with adjustable packaging parameters.
• Designed for continuous, long-term high-speed operation.

Working principle — Automatic heat shrink packaging machine

• Feed system: products are positioned on a conveyor or feed line.
• Packaging material supply: heat-shrink film or bags are unwound from rolls.
• Sealing and cutting: film/bags are cut and sealed to size.
• Heat-shrinking: products pass through a continuous oven or shrink tunnel to obtain a tight fit.
• Cooling and setting: cooled to stabilize the shrink-fit packaging.

Features and advantages

• High measurement accuracy and efficient throughput.
• Ergonomic layout and straightforward operation.
• Compact footprint to save production space.
• Flexible format changeover for different product sizes and shapes.
• Reliable sealing and preservation when suitable materials are used.
• Suitable for single-item packaging as well as block or strip arrangements.

Technical specifications

• Control: PLC control with frequency-conversion speed regulation.
• Automatic functions: automatic counting, display of bag length and packaging speed.
• Temperature control: PID automatic temperature regulation.
• Material tracking: photoelectric (color-mark) tracking for printed films.
• Safety & diagnostics: overload protection, leakage protection, alarm and self-diagnostic fault display.
• Positioning & cutting: digital cut-off position control for high-precision cuts and reduced film waste.
• Compatible packaging materials: plastic film, heat-shrink film, and bottom paper for paper-based models.
