1、 Preparation before operation
1. Equipment inspection
Check for residual glass shards, tools, and other foreign objects on the machine to ensure cleanliness.
Check the gear fit of the transmission mechanism and add disinfectant lubricating oil.
Whether the manual turning test equipment runs smoothly and avoids jamming.
2. Parameter validation
Confirm that the vacuum system has undergone sterilization and filtration, and the pressure has been expressed to the required value.
Check whether the nitrogen is sterilized and filtered, and whether the pressure gauge is normal.
3. Component adjustment
Adjust the position of the spiral rod and funnel to avoid collision that may cause an alarm.
Select a screw and lower nozzle with appropriate pitch (6-12mm) and aperture (6-8mm) according to the characteristics of the powder.
2、 Control during operation
1. Quantity adjustment
Set the frequency (5000-8000 steps/second), number of steps (controlling loading), and number of turning steps (controlling screw angle) through the PLC system.
Before production, 6-10 bottles need to be continuously sampled to verify the accuracy of the filling volume. Only after passing the inspection can formal production be carried out.
2. Exception handling
The difference in loading capacity may be due to improper screw position or one-way clutch failure, requiring readjustment or replacement of components.
Abnormal sealing of the rubber plug requires checking the amount of silicone oil, balance of the oscillator, and position of the robotic arm.
3、 Maintenance and safety
1. Regular maintenance
Clean the interior of the equipment to prevent contamination from medication powder.
Check the wear of the blade and replace it in a timely manner to ensure the accuracy of the packaging.
2. Safety regulations
Operators need to wear protective equipment and be familiar with the location of the emergency stop button.
Regularly train operators to ensure mastery of equipment operation and troubleshooting skills.
4、 Frequently Asked Questions
1. Powder contamination: It may be due to the infiltration of screw bearing oil, and the packaging head needs to be disassembled, cleaned, and sterilized.
2. Automatic shutdown: Check the humidity of the medicine powder or controller malfunction, and use a multimeter if necessary.
