Precautions for using powder filling and sealing machine
Precautions for using powder filling and sealing machine
Powder filling and sealing machines are widely used in industries such as food, pharmaceuticals, and chemicals. Proper operation and maintenance can ensure production efficiency, packaging quality, and equipment lifespan. The following are key usage precautions:
1. Preparation before equipment operation
Check the power and gas sources: Ensure stable voltage and air pressure to avoid equipment malfunctions caused by voltage fluctuations or insufficient air pressure.
Cleaning and disinfection: The food and pharmaceutical industries need to strictly implement CIP (online cleaning) or SOP cleaning procedures to prevent cross contamination.
Calibration measurement system: Regularly calibrate the weighing sensor or volumetric filling system to ensure the accuracy of the filling volume (error ≤± 1%).
2. Precautions during operation
Powder characteristic adaptation: Different powders (such as milk powder, coffee powder, additives) have different flowability and density, and vibration feeding, screw speed or nitrogen filling parameters need to be adjusted to avoid blockage or uneven filling.
Sealing temperature control:
Heat sealing machine: Set the appropriate temperature according to the packaging material (such as aluminum foil, PE film). If it is too high, it is easy to burn through, and if it is too low, the sealing will not be firm.
Ultrasonic sealing: requires adjustment of frequency and pressure, suitable for materials that are prone to heat sensitivity.
Prevent dust pollution:
The equipment should be equipped with dust removal devices (such as negative pressure powder suction systems) to avoid dust accumulation affecting sensors or motors.
It is recommended to operate easily hygroscopic powders (such as protein powder) in low humidity environments or use nitrogen protection.
3. Daily maintenance and upkeep
Regular lubrication: Use food grade lubricating oil for moving parts such as guide rails and bearings to avoid dry friction.
Key component inspection:
Sealing mold: Clean up residual materials to prevent carbonization from affecting the sealing quality.
Photoelectric sensor: Clean the mirror surface to avoid misjudgment and packaging misalignment.
Record operational data: Monitor equipment status through PLC or IoT systems to provide early warning of potential faults (such as motor overheating and abnormal air pressure).
4. Safety regulations
Emergency stop device test: Ensure quick shutdown in case of emergency.
Anti static measures: Flammable powders (such as milk powder and cocoa powder) must be grounded during filling to prevent static sparks.
Operator protection: Wear a dust mask to avoid long-term inhalation of fine powder.
5. Fault handling
common problem:
Poor sealing: Check temperature, pressure, or mold wear.
Decreased filling accuracy: Clean the screw or recalibrate the sensor.
Shutdown handling: When there is a malfunction, power/gas should be cut off first, and forced operation is strictly prohibited.
summarize
Proper use of powder filling and sealing machines requires attention to material compatibility, parameter adjustment, cleaning and maintenance, and safety standards. Regular maintenance and intelligent monitoring can significantly reduce the failure rate, improve production efficiency and product qualification rate.
