The surface of the pre filled filling capping machine is made of SUS304 stainless steel, and the parts in contact with the material are made of SUS316L stainless steel and medical grade silicone rubber, which meets the requirements of GMP specifications. This machine is widely applicable to various types of pre filled syringes, and special types of syringes can also be customized.
Process flow of operating pre filled filling capping machine
Preparation before startup: Check the integrity of machine components, ensure stable connection of power and air sources (such as compressed air on), and remove surrounding obstacles. Install the filling head and capping head, adjust the positioning bolt to accurately align the bottle mouth position, and avoid damage caused by manual tapping.
• Parameter setting and startup: Adjust the filling volume through a quantitative valve or flow meter (with a control error within ± 3%), and match the capping torque to the material requirements of the bottle cap; After starting the machine, monitor the filling accuracy and sealing of the screw cap, and use sensors to provide real-time feedback on any abnormalities.
• Operation monitoring: During the production process, observe the consistency of the filling volume and the tightness of the screw cap. If there is a stuck bottle, immediately stop and manually reverse to remove foreign objects to prevent damage to the star wheel caused by forced operation.
• Shutdown and instant cleaning: Follow the principle of "idle discharge" to turn off the feed, and turn off the power after the material is emptied; Wipe the contact parts with a neutral cleaner and disinfect them with 75% alcohol, with a focus on removing any residue inside the filling needle.
Maintenance measures for operating pre filled filling capping machine to extend equipment life
Daily cleaning standards: Rinse the filling valve and capping head pipeline after each shutdown to avoid residue crystallization and blockage; Compressed air dust removal is used for electrical control cabinets, and the thickness of dust accumulation in the heat dissipation holes should be less than 1mm to prevent overheating
• Key component inspection: Check the tightness of the drive belt weekly and inspect the silicone sealing ring for aging and cracking monthly; The synchronous belt teeth are worn or cracked and need to be replaced immediately
Scientific lubrication management: Apply food grade grease to the transmission gears and guide rails every week to avoid excessive oil sludge; The gearbox uses ISO VG 220 gear oil, which is replaced every 2000 hours and ensures the cleanliness of the "three-stage filtration".
Preventive operating habits: Control the torque of the screw cap to match the material of the bottle cap, reducing the risk of servo motor overload; New employees are required to complete a 20 hour simulation training and record any abnormal vibrations or noises during shift handover.
Professional Regular Maintenance: Calibrate the filling accuracy with a laser instrument every month (calibrate the flow meter when the error exceeds ± 1ml), check the accuracy of the torsion shaft every six months, and conduct a comprehensive inspection of the air circuit solenoid valve and circuit relay during annual maintenance
Strictly following operating standards and maintenance procedures can reduce failure rates by over 60% and extend equipment lifespan by three years.
