Weighing and Packaging System with Double Conveyor | High-Speed Dual-Feed Automatic Packaging Line

Industry Pain Points We Solve

• ·Single-feed conveying systems have severe capacity bottlenecks, unable to meet high-volume continuous production demands, while frequent manual feeding leads to high labor intensity and low production efficiency

• ·Single-line elevator failure causes full production line shutdown, resulting in long unplanned downtime and extremely low overall equipment efficiency (OEE)

• ·Uneven feeding of single conveying systems leads to unstable material supply for the multihead weigher, causing large weighing deviation, serious product giveaway and high raw material waste

• ·Traditional conveying design causes high breakage rate for fragile products (puffed snacks, nuts, confectionery), leading to low finished product yield and profit loss

• ·Dispersed equipment layout occupies excessive workshop space, with high installation, operation and maintenance costs

• ·Poor equipment compatibility requires long downtime for format changeover between different materials and packaging specifications

• ·Lack of signal linkage between weighing and packaging units leads to frequent material jamming, inaccurate filling and high defect rate

Our Tailored Integrated Solution

We provide a high-speed, fully automatic Weighing and Packaging System with Double Conveyor, an end-to-end integrated packaging solution designed for high-volume continuous production of bulk solid products. This system seamlessly combines a dual-line bowl-type elevator, food-grade supporting platform, high-precision 14-head multihead weigher and automatic packaging machine, perfectly solving core pain points of single-feed systems such as capacity bottlenecks, unplanned downtime and uneven feeding. It realizes fully automated, stable and efficient production from raw material feeding to finished packaged product output, adapting to a wide range of industries including food, snack, grain, pet food, hardware and more.

Core System Units

1. ·Double Line Bowl-Type Elevator

   The core feeding unit with dual-line independent conveying design, supporting synchronous dual-feed operation or separate single-line operation according to production needs. The food-grade bowl-type structure ensures gentle, damage-free and spill-free material conveying, effectively reducing breakage of fragile products. The dual-line design doubles feeding capacity, reduces manual feeding frequency, and guarantees continuous and stable material supply to the upstream weigher. The main body is constructed with SUS 304 stainless steel, fully compliant with global food safety standards.
2. ·Food-Grade Supporting Platform

   Ergonomic heavy-duty stainless steel supporting platform with anti-slip design, providing safe and convenient operation and maintenance access for the multihead weigher and upper equipment. The structure fully meets food workshop hygiene standards, with an open design for easy cleaning and daily maintenance.
3. ·14-Head High-Precision Multihead Weigher

   The core quantitative weighing unit, with real-time signal linkage with the downstream packaging machine to achieve on-demand accurate discharging. The 14-head independent weighing structure delivers ultra-high weighing accuracy and high-speed weighing performance, perfectly matching the stable material supply from the dual-line elevator. It adapts to a wide range of bulk materials, from fine grains to irregular bulk solids, ensuring consistent weight of every single package.
4. ·Automatic Packaging Machine

   The end packaging unit seamlessly connected with the multihead weigher, completing automatic bag forming, filling and sealing in one continuous process. It is compatible with multiple bag formats (pillow bag, 3-side seal, 4-side seal, stand-up pouch) and various weight specifications, with stable sealing performance to ensure product freshness and extended shelf life.

Standard Automated Workflow

1. ·Dual-Line Material Feeding & Lifting: Bulk materials are manually poured into the dual inlets of the double line bowl-type elevator, which lifts the materials smoothly and synchronously to the upper feeding hopper of the 14-head multihead weigher, ensuring continuous and uniform material supply.

2. ·High-Precision Quantitative Weighing: The 14-head multihead weigher completes high-accuracy quantitative weighing of materials according to the set target weight, with real-time signal interconnection with the downstream packaging machine to achieve precise on-demand discharging.

3. ·Automatic Packaging & Finished Product Output: Weighed materials are dropped accurately into the automatic packaging machine, which completes fully automatic bag forming, filling and sealing, and outputs the final packaged products, closing the full production cycle.
