Working principle and structural characteristics of strip back sealed powder packaging machine
Date: 2025-06-20Read: 5
The strip back sealed powder packaging machine is designed to meet the production needs of enterprises using popular strip back sealed packaging bags, and is suitable for small dose packaging in industries such as pharmaceutical powders, food, and health products. Such as Sanqi powder, Chenpi powder, Danshen powder, Lingzhi spore powder, etc.
The working principle of the strip back sealed powder packaging machine mainly includes the following steps:
Material conveying: Powdered materials enter the feeding system of the packaging machine through a hopper. The feeding system is usually composed of a screw or a vibrating feeder. The screw feeder pushes the powder forward through the rotation of the screw, while the vibrating feeder uses the principle of vibration to evenly flow the powder into the packaging area.
Quantitative filling: After the material reaches the quantitative filling area, the packaging machine will use volumetric or weighing quantitative methods. Volumetric quantification determines the amount of material to be filled each time by measuring the volume of the container, while weighing quantification uses high-precision weighing sensors to measure the weight of the material in real time and stops filling when the preset weight is reached.
Packaging molding: After filling the material, the packaging material (such as plastic film) is pulled down from the roll, folded into a bag shape by the molding device, and then heated and sealed by the heat sealing device.
Finished product output: The packaged finished products are sent out of the packaging machine through a conveyor belt or other output device and enter the next production process, such as packing, labeling, etc.
The structural characteristics of the strip-shaped back sealed powder packaging machine include:
Controller: The controller usually uses Chinese characters for display, which is reliable and easy to operate, and the photoelectric control system has strong resistance to light and electrical interference.
Bag making system: using stepper motor subdivision technology, the bag making accuracy is high and the error is small.
• Photoelectric control system: Integrated photoelectric positioning technology enables closed-loop control of the bag making, filling, and sealing stations, improving packaging speed and accuracy.
Dust removal system: Through the dual effects of negative pressure adsorption and vibration screening, it avoids powder dust and ensures a clean working environment.
• Nitrogen displacement device (optional): Inject inert gas before sealing to extend product shelf life.
These characteristics make the strip-shaped back sealed powder packaging machine perform well in automated packaging of powdered materials, suitable for industries such as milk powder, seasonings, and pharmaceutical intermediates.
