Heavy Duty Multifunction Laminated Bag Making Machine

Single unwinding without transverse deviation correction (with pneumatic feeding):

The single unwinding unit with pneumatic feeding system stands as a cornerstone of operational efficiency, featuring a maximum unwinding width of 1200mm to accommodate large-format laminated films. Its pneumatic feeding mechanism ensures consistent material tension control, eliminating the need for transverse deviation correction by maintaining precise alignment through air pressure regulation. This design reduces material waste by 15% compared to traditional systems while supporting film thicknesses from 0.08mm to 0.3mm. The integration of servo motor-driven unwinding ensures synchronization with the machine's maximum speed of 170pcs/min, enabling seamless material flow even during high-speed production runs. Operators benefit from quick roll changeovers, with hydraulic loading capabilities that handle rolls up to Φ800mm diameter, minimizing downtime between production batches.

Triangle folding + traction mechanism:

The triangle folding and traction system delivers exceptional precision in forming gusseted bags, with adjustable folding angles ranging from 25° to 60° to accommodate various bag styles including stand-up pouches and side-gusseted packages. Its servo synchronization technology ensures traction speed matches the machine's 170pcs/min output, maintaining consistent bag dimensions with ±0.5mm length accuracy. The mechanism employs dual traction rollers with rubberized surfaces to prevent slippage, even when processing slippery laminated materials like PET/PE composites. This component's modular design allows tool-free changeovers between bag types, reducing setup time by 40% and supporting quick transitions from three-side seal to stand-up pouch production. The integration of photoelectric sensors further enhances precision by detecting material edges and adjusting folding parameters in real-time.

Triangle folding + traction mechanism:

The triangle folding and traction system ensures superior precision in gusseted bag formation, featuring an adjustable folding range of 25° to 60° to support multiple bag configurations such as stand-up pouches and side-gusseted bags. Utilizing servo synchronization technology, the system maintains precise speed alignment with the machine's output of 170 pieces per minute, achieving consistent bag length accuracy within ±0.5mm. Equipped with dual rubber-coated traction rollers, the mechanism effectively resists slippage—even when handling smooth laminated materials such as PET/PE composites. A modular design enables tool-free changeovers between bag types, cutting setup time by 40% and facilitating rapid transitions from three-side seal bags to stand-up pouches. Integrated photoelectric sensors further enhance operational accuracy by continuously detecting material edges and dynamically adjusting folding parameters in real time.

Vertical sealing 5 groups, used for sealing three side sealing, standing bag bottom sealing, etc.:

The five-group vertical sealing system provides unmatched versatility for complex bag structures, capable of forming three-side seals, stand-up pouch bottom seals, and gusseted side seals in a single pass. Each sealing group features independent temperature control (0-300°C) with PID regulation, ensuring consistent heat distribution across the 1200mm sealing width. The system's servo-driven actuators apply precise pressure (0.2-0.6MPa) to create hermetic seals with peel strengths exceeding 12N/15mm—30% higher than industry standards. Tool-less seal width adjustment (10-60mm) allows customization for different product requirements, while the inclusion of non-stick Teflon coating on sealing jaws reduces material adhesion and extends maintenance intervals. This configuration supports production of multi-compartment bags and vacuum-sealed packages, making it ideal for food, pharmaceutical, and industrial packaging applications.

Horizontal sealing part: (3 groups, cast iron type):

The three-group horizontal sealing unit utilizes heavy-duty cast iron construction to deliver superior heat stability and durability during continuous operation. Each sealing group maintains temperature uniformity within ±1°C across the sealing surface, ensuring consistent seal quality even at maximum production speeds. The cast iron components provide exceptional thermal mass, reducing temperature fluctuations during high-speed cycles and extending seal jaw lifespan to 800,000 cycles—twice the service life of standard steel units. This system features independent pressure adjustment (0.3-0.8MPa) and variable dwell time control (0.1-3 seconds), accommodating diverse materials from thin films to thick laminated structures. The inclusion of water-cooled sealing jaws prevents overheating during extended runs, while precision-ground sealing surfaces ensure flatness within 0.02mm/m for leak-proof seals.

Collection desk part:

The automatic collection desk integrates advanced stacking technology to handle finished bags with precision and efficiency, supporting output rates up to 170pcs/min without jamming. Its servo-driven conveyor system features adjustable speed and stacking height, accommodating bag sizes from 50x50mm to 580x420mm. The desk's pneumatic pushers and retractable guides ensure neat, uniform stacking with ±2mm alignment accuracy, reducing manual sorting labor by 70%. An integrated counting system with batch separation allows preset quantity grouping (10-100pcs/batch), while a reject mechanism diverts defective bags based on upstream quality checks. The collection desk's modular design includes optional extensions for connecting to downstream packaging equipment, creating a seamless end-to-end production line. Constructed with stainless steel surfaces, it meets food-grade hygiene requirements and simplifies cleaning procedures.
