Overall Production Workflow
GS Screw Feeder (Precision Material Conveying) → HDCK420 Vertical Packing Machine (Bag Forming, Filling, Sealing & Cutting) → ZH120 Cartoning Machine (Automatic Box Packing & Gluing Sealing) → BS Film Sealing & Shrinking Machine (Integrated Film Wrapping & Heat Shrink Finishing) → Finished Product Output
The entire production process adopts fully automated closed-loop control without manual intervention. All equipment is electrically synchronized and mechanically matched, eliminating production bottlenecks, ensuring stable operation rhythm, and achieving consistent packaging quality and continuous mass production capacity.
Core Equipment Detailed Introduction
1. GS Screw Feeder | Precision Quantitative Feeding System
As the front-end core feeding equipment of the entire production line, the GS Screw Feeder undertakes stable and quantitative conveying of various powder and fine granular materials. Adopting high-precision servo screw metering technology, it features stable feeding pressure, uniform material output, and ultra-low measurement deviation, perfectly adapting to free-flowing, semi-fluid, and ultra-fine dusty powders that are difficult for conventional feeding equipment to handle.
Equipped with independent servo drive and PLC intelligent frequency conversion control, the feeder supports stepless adjustment of feeding speed and conveying volume, realizing one-click parameter switching for different material specifications and packaging dosages. The fully sealed feeding structure effectively prevents powder flying, material leakage, and dust pollution, maintaining a clean production environment. All material contact parts are made of food-grade 304 stainless steel, featuring no material residue, easy disassembly and cleaning, and fully compliant with GMP hygiene standards for food and pharmaceutical production. With fast response speed, low noise, and low failure rate, it provides continuous and stable material supply for the downstream packaging host, laying a solid foundation for high-precision and high-efficiency packaging.
2. HDCK420 Vertical Fully Automatic Bag Packing Machine | Core Form-Fill-Seal Host
The HDCK420 vertical packing machine is the core host equipment of the entire production line, integrating automatic film unwinding, bag forming, quantitative filling, vertical and horizontal sealing, date coding, fixed-length cutting, and finished bag output in one continuous process. It abandons the traditional semi-automatic split process and realizes truly unmanned vertical packaging operation, greatly improving production efficiency and packaging consistency.
This machine adopts advanced dual-servo synchronous control system, with independent PID constant temperature control for vertical and horizontal sealing. The sealing temperature deviation is controlled within ±1℃, ensuring flat, firm, wrinkle-free and leak-proof sealing edges. It is compatible with various composite packaging films such as PE, PET, and aluminum-plastic films, effectively isolating moisture, oxygen, and dust, extending product shelf life, and avoiding powder agglomeration and deterioration.
Supporting flexible packaging specification adjustment, the HDCK420 can adapt to multiple bag widths, lengths, and filling dosages, covering small-dose trial packaging to large-dose bulk packaging. The industrial touch screen human-machine interface stores multiple product formulas, enabling one-click model switching without repeated parameter debugging. The optimized mechanical structure reduces operating vibration and material jamming, ensuring long-term stable continuous operation. Widely applicable to probiotic powder, meal replacement powder, coffee powder, seasoning powder, Chinese medicine powder, chemical powder and other materials, it meets the diversified packaging needs of modern industrial production.
3. ZH120 Automatic Cartoning Machine | Secondary Intelligent Packaging Module
The ZH120 cartoning machine is the secondary packaging core equipment of the production line, specially customized for finished pouch products from the HDCK420 packaging host. It automatically completes carton picking, carton opening, finished bag sorting and loading, precise gluing, box pressing and shaping, and finished carton discharging, realizing fully automated box packaging of single or multiple pouch products.
Adopting high-speed synchronous transmission structure and photoelectric intelligent sensing positioning, the machine accurately identifies product and carton positions, effectively avoiding empty cartons, missing packaging, and multi-packaging errors. The precision gluing system achieves uniform glue output and firm bonding without glue overflow or carton opening, ensuring neat and standardized carton appearance. With flexible specification switching function, it adapts to cartons of different sizes and styles, supporting mixed production of multiple products.
Replacing traditional manual cartoning operations completely, the ZH120 machine solves the pain points of low manual efficiency, irregular packaging, and high labor costs. It features stable operation, low failure rate, and strong compatibility, perfectly docking with upstream packaging equipment and downstream shrinking machines to form a smooth and efficient full-process packaging chain.
4. BS Film Sealing & Shrinking Machine | Final Finishing & Protective Packaging
As the final process equipment of the entire production line, the BS Film Sealing & Shrinking Machine is responsible for automatic film wrapping, edge sealing, and thermal shrinkage finishing of cartoned finished products. Adopting constant-temperature hot air circulation shrink technology, it features uniform heating, fast shrinkage speed, and stable molding effect.
The high-precision sealing cutter ensures flat and neat sealing edges without sticking or breaking the film. The circulating hot air system makes the shrink film tightly fit the carton surface without wrinkles, looseness, or deformation, realizing dust-proof, moisture-proof, and anti-counterfeiting sealed packaging. The finished shrink-wrapped products are neat, beautiful, and high-grade, effectively improving product market competitiveness, and suitable for supermarket retail, e-commerce distribution, and export packaging standards.
The machine supports fully automatic continuous operation, with operating speed synchronously matched with the upstream cartoning machine. It features energy-saving operation, simple maintenance, and strong stability, which can meet the requirements of long-term mass production and high-standard finished product output.
