In the field of pharmaceutical production, pre filled syringes, as an advanced form of drug packaging, are increasingly being widely used. It can not only effectively improve the convenience of drug use, but also greatly ensure the quality and safety of drugs during storage and use. And the matching filling machine technology has become a key factor in determining the efficiency and quality of drug production. Developed by Wenzhou Aoji Intelligent Technology Co., LtdPre filled syringe filling machineWith a series of advanced technologies and innovative designs, it stands out in the industry and brings new solutions to pharmaceutical production enterprises.
1、 Material selection that prioritizes hygiene and safety
Aoji Intelligent Pre filled Syringe Filling MachineStrictly follow high standards in material selection. The overall framework of the equipment is made of SUS304 stainless steel, which has good strength and corrosion resistance, ensuring that the equipment is not easily damaged during long-term use and can adapt to various production environments. For parts that come into direct contact with drugs, such as filling pipelines and pistons, SUS316L stainless steel and medical grade silicone rubber are used. SUS316L stainless steel has superior acid and alkali corrosion resistance, which can effectively avoid pollution risks caused by reactions with chemical substances in drugs; Medical grade silicone rubber has good biocompatibility, non-toxic, odorless and other characteristics, which comply with medical and health standards, ensuring the quality and safety of drugs from the source and meeting the strict requirements of GMP (Good Manufacturing Practice).
2、 High precision filling technology core
Quantitative filling of ceramic plunger pumpThe filling machine adopts ceramic plunger pump as the key component for quantitative filling. Ceramic materials have excellent physical and chemical properties, strong resistance to acid and alkali erosion, and can cope with various complex drug compositions. They are also wear-resistant and high-temperature resistant. During the filling process, the ceramic plunger pump achieves precise extraction and pushing of the liquid medicine through precise reciprocating motion. By utilizing advanced control algorithms and high-precision displacement sensors, the filling accuracy can be controlled within a very small error range, meeting the high requirements for dosage accuracy in pharmaceutical production. For example, for common 1ml pre filled syringes, the filling accuracy can be stably controlled within ± 0.8%, ensuring the accurate dosage of the drug in each syringe and providing a solid guarantee for the stability of drug efficacy.
Injection needle rises with the liquid level for fillingIn order to avoid splashing and bubble mixing during the filling process, the Aoji filling machine innovatively adopts a filling method where the injection needle rises with the liquid level. During filling, the injection needle is always kept below the liquid level of the medicine, and as the medicine is continuously injected, the needle rises slowly and synchronously. This filling method effectively reduces the contact area between the liquid medicine and air, reduces the possibility of bubble generation, and also avoids waste caused by splashing of the liquid medicine and pollution of the filling environment, further improving the stability of drug quality.
3、 Rubber stopper processing and conveying technology
Ordered sorting of vibration discsThe correct sorting and transportation of rubber stoppers are crucial for the integrity of drug packaging. The Aoji pre filled syringe filling machine is equipped with a vibration disc device, which can quickly and orderly arrange the disorderly rubber plugs by accurately controlling the vibration frequency and amplitude. The vibration disc is made of SUS316L stainless steel clean disc, which has undergone special surface treatment to ensure that there are no clean dead corners inside the disc, avoiding contamination of the rubber plug during transportation. At the same time, the design of the vibration disc also considers the different sizes and material characteristics of the rubber plugs, which can adapt to the sorting requirements of various specifications of rubber plugs.
Removable sterilization top plateIn order to further ensure the hygiene and safety of the rubber stopper transportation process, the top plate of the vibrating plate of the filling machine is designed as a detachable structure and supports high-temperature sterilization treatment. Before and after the use of the equipment, the operator can remove the top plate and put it into the sterilization equipment for disinfection, effectively killing possible microorganisms and preventing contamination of drug packaging, providing strong support for the sterile environment of drug production.
4、 Electrical Control and Intelligent Design
International brand electrical componentsIn terms of electrical control, the Aoji intelligent filling machine uses international brand electrical components, which have the advantages of high reliability and strong stability. Adopting a non interfering modular control mode, the electrical control system of the entire equipment is divided into multiple independent functional modules, each responsible for specific control tasks. This not only facilitates maintenance and repair, but also effectively reduces electrical interference between modules, ensuring the accuracy and reliability of equipment operation.
PLC programming and human-computer interaction interfaceThe operation of the equipment is comprehensively regulated by a PLC programming controller. Operators can easily set and adjust various parameters of the equipment, such as filling dosage, filling speed, and rubber stopper conveying frequency, through an intuitive human-computer interaction interface. At the same time, the human-computer interaction interface can also monitor and display the working status of each workstation in real time, including equipment operating speed, cumulative output, fault alarm information, etc. Once the equipment malfunctions, the system can quickly and automatically sound an alarm, and clearly display the fault location and detailed prompt information on the interface, helping operators quickly locate and solve problems, greatly improving the convenience of equipment operation and maintenance efficiency.
Multiple filling doses and formula storageConsidering that pharmaceutical production enterprises may need to fill different specifications and types of drugs, the Aoji filling machine provides multiple filling dosage options, ranging from trace amounts of 0.1ml to larger capacities of 50ml, all of which can be accurately filled through equipment parameter settings. In addition, the device also supports multiple formula parameter storage functions. Enterprises can pre store the filling process parameters of different drugs in the device, and can quickly switch between producing different products with just one click during production, greatly improving production flexibility and efficiency.
