Double Spiral Feeding Hopper Less Packaging Machine

The double spiral feeding hopper less packaging machine (packaging scale) is a new generation of intelligent packaging scales developed by our company. It uses three high-precision weighing sensors. The feeding mechanism uses double helix fast, medium, and slow three-speed inverters to control the feeding, ensuring high weighing and measuring accuracy, fast packaging speed, and high output. The hopper and screw in contact with materials can be equipped with stainless steel; The weighing control adopts frequency conversion control technology, weighing error automatic compensation, and correction technology; It applies to the selection of materials with poor flow and enterprises with fast packaging requirements and large output.

What Is Double Spiral Feeding Hopper Less Packaging Machine?

When operating the double spiral feeding hopper-less packaging machine, the packaging bag is manually hung on the conveyor, the start button is pressed, and the material in the silo is transported into the packaging bag through the screw conveyor. First, the large and small screws work simultaneously to quickly feed the material into the packaging bag. When the material approaches the set weight, the large screw stops working, and the small screw continues to work, slowly feeding the material into the packaging bag, Stop the small spiral work when the weight reaches the set weight, resulting in high packaging accuracy.

When packaging with a weighing hopper, the material is first placed in a weighing hopper. After weighing the material, it can be manually placed in the pocket and placed directly into the pocket to improve packaging speed.

After the material is loaded into the pocket, the clamp is automatically opened, and the filling part is completed. It is conveyed by a belt conveyor on one side below, passing through a sewing machine at the back, and the sewing thread is completed for packaging.
