Powder packaging machine is an automated equipment specially used for quantitative packaging and packaging of powdered materials. It is widely used in food, medicine, chemical, pesticide, feed and other industries.
The following is its core introduction:
1. Main functions
Quantitative packaging: Accurately measure powder (such as milk powder, seasoning, drug powder, dye, etc.) to ensure consistent weight of each bag.
Automatic filling: High-precision filling is achieved through spiral propulsion, volumetric measurement or weighing sensor.
Sealing molding: Supports back sealing, three-side sealing, four-side sealing and other packaging forms, and is compatible with a variety of bag types (such as self-supporting bags, pillow bags).
Dust-proof design: Avoid powder flying and ensure a clean production environment (especially for toxic or dusty materials).
2. Equipment type
According to the degree of automation:
Semi-automatic: requires manual assistance for bagging or starting, suitable for small batch production.
Fully automatic: Automatically completes bagging, metering, filling, sealing, coding and other processes with high efficiency.
By metering method:
Screw metering type: The amount is controlled by the number of spiral rotations, suitable for powders with good fluidity.
Weighing type (net weight/gross weight): Uses high-precision sensors, suitable for materials that are easy to absorb moisture or have unstable density.
Volumetric cup type: Measuring by fixed volumetric cup, simple and economical.
3. Core structure
Feeding system: hopper, stirring device (anti-caking), feeding screw.
Measuring system: high-precision screw or weighing module driven by servo motor.
Bag making/filling system: automatic film forming, filling, and heat sealing.
Control system: PLC or microcomputer control, adjustable parameters (such as weight, speed, temperature).
Auxiliary functions: coding machine, nitrogen filling preservation, static elimination, etc. are optional.
4. Technical parameters
Packing speed: 20-60 bags/minute (depending on the model).
Measuring range: usually 50g-5kg, can be customized for micro-amounts (such as 1g) or large specifications.
Accuracy: ±0.5%-1% (higher for weighing type).
Applicable materials: roll packaging materials such as composite film, aluminum foil, PE, etc.
5. Industry application
Food: milk powder, coffee powder, flour, additives, etc.
Medicine: Chinese medicine powder, granules, disinfectants.
Chemical industry: dyes, coatings, laundry detergents.
Agriculture: pesticides, fertilizers, feed premixes.
