NJP-1200D Automatic Capsule Filling Machine: Advanced Functions and Outstanding Effects

1. Efficient and Stable Powder Feeding Function
The core of the NJP-1200D's powder feeding function lies in its newly designed powder hopper, which adopts a butterfly valve - type powder feeding structure combined with a dedicated vibration unit. This design targets the common problem of poor fluidity in drug powders, especially Chinese herbal medicines and Chinese patent drugs. In traditional screw feeding devices, powders with poor fluidity often agglomerate or get stuck in the feeding channel, leading to intermittent feeding, uneven powder supply, and even production interruptions. However, the vibration unit of the NJP-1200D's powder hopper applies continuous and gentle vibration to the powder, forcing it to break up agglomerates and flow downward smoothly. The butterfly valve - type feeding mechanism further controls the powder feeding speed accurately, ensuring that the powder is supplied to the filling station at a stable and uniform rate. This function not only avoids the powder feeding failure caused by poor fluidity but also lays a solid foundation for the subsequent accurate filling of capsules, ensuring that each capsule receives the correct amount of powder.
2. Reliable Capsule Handling and Powder Waste Prevention Function
2.1 Capsule Separation and Orientation
The NJP-1200D is equipped with a high - performance capsule hopper and a new type of seeder rack. The capsule hopper stores empty capsules in an orderly manner and transports them to the seeder rack smoothly. The seeder rack adopts a guideway transmission mechanism, which has high operational precision. Unlike traditional transmission structures that are prone to wear and tear, the guideway transmission ensures that the seeder rack moves stably and accurately during operation, reducing the error caused by mechanical vibration. At the same time, the enclosed design of the seeder rack effectively prevents waste capsules and dust from entering the internal mechanism. Waste capsules, if mixed into the normal capsule flow, may cause jamming of the seeding system, while dust can accumulate on the transmission parts, affecting the service life and precision of the equipment. By blocking these impurities, the seeder rack ensures rapid and orderly seeding of empty capsules and accurate orientation of each capsule. This means that each empty capsule can be accurately aligned with the mold hole, avoiding the problem of capsule misalignment that leads to filling failure or unqualified capsules.
2.2 Powder Aspiration and Waste Reduction
The integrated powder aspirator is a key functional component that works in conjunction with the capsule hopper. During the capsule separation process, abnormal capsules (such as deformed, damaged, or incompletely formed capsules) may fail to separate normally. In such cases, if the powder is still filled into the lower mold hole as usual, the powder will fall onto the mechanical platform, resulting in waste and potential pollution to the equipment and the production environment. The powder recovery device of the integrated powder aspirator is activated immediately at the filling station. It generates a stable negative pressure to directly inhale the powder that would enter the lower mold hole (due to abnormal capsule separation) into the powder collector. This function not only prevents powder from falling onto the mechanical platform, keeping the equipment clean and reducing the workload of manual cleaning but also recovers the powder for potential reuse (after subsequent treatment in line with production standards), minimizing powder waste. For pharmaceutical manufacturers, especially those producing high - value drugs, this function significantly reduces production costs and improves resource utilization.
3. High - Precision and Low - Maintenance Turntable Operation Function
The turntable is the core moving part of the NJP-1200D, responsible for transporting capsules through different stations (such as capsule separation, powder filling, capsule locking, etc.) to complete the entire filling process. The NJP-1200D's turntable adopts a one - piece processing forming ten - position turntable frame, which has a series of advantages that traditional spliced turntable frames cannot match. First, the one - piece structure eliminates splicing gaps. In traditional spliced turntables, gaps between splicing parts may allow powder to leak into the internal mechanism of the turntable, causing wear to moving parts and affecting the precision of the turntable. The NJP-1200D's turntable, with no splicing gaps, has excellent sealing performance, effectively preventing powder leakage. Second, the turntable's modules have optimized movement modes: the lower die performs horizontal telescopic movement, and the module undergoes vertical lifting movement. These movements are precisely coordinated to ensure that capsules are stably clamped and transported at each station, avoiding capsule damage or displacement during movement.
In addition, the fixed bracket shaft seal of the turntable module uses an oil - and dust - proof lip skeleton shield. This shield not only prevents lubricating oil from leaking out of the shaft seal (avoiding oil pollution to the powder and capsules) but also blocks external dust from entering the shaft seal, ensuring that the shaft seal remains in a clean and lubricated state for a long time. The combination of these designs enables the turntable to achieve no noise, small volume, small load, and high precision during operation. More importantly, the fully enclosed structure of the turntable and the high - quality shaft seal design allow it to operate continuously for three years without the need for maintenance, refueling, or powder cleaning (Patent No.: ZL 2015 2 1021530.0). This function greatly reduces the downtime of the equipment for maintenance, improves the utilization rate of the equipment, and reduces the maintenance cost for manufacturers.
4. Accurate and Flexible Drug Filling Function
4.1 Negative Pressure - Assisted Powder Recovery in Filling Base
The filling base of the NJP-1200D is designed with a negative pressure internal structure connected to the powder collector, which solves the problem of powder leakage during high - speed filling. During the high - speed operation of the equipment, even with the most precise filling mechanism, a small amount of powder may leak into the filling base. If this powder is not handled in time, it will accumulate in the base, causing corrosion to the base's internal parts and affecting the precision of the filling mechanism. The negative pressure design of the filling base generates a stable negative pressure in the base hole when the equipment is running. This negative pressure sucks the leaked powder into the recycling equipment, and after being filtered by the powder collector, the powder is collected uniformly. The collected powder can be re - input into the production process after meeting the quality standards, avoiding powder waste and preventing the filling base from being corroded by the powder. This function not only improves the utilization rate of raw materials but also extends the service life of the filling base and ensures the long - term stability of the filling precision.
4.2 Modular Filling Adjustment
The NJP-1200D adopts a modular design for the drug filling unit, and the filling gripper uses pin positioning. In traditional capsule filling machines, when adjusting the filling load (i.e., the amount of powder in each capsule) or replacing different types of filling rods (to adapt to powders of different particle sizes and fluidities), the production line must be stopped. This not only reduces production efficiency but also increases the risk of human error during adjustment. However, the modular design of the NJP-1200D allows operators to adjust the filling load without stopping production. The pin positioning of the filling gripper ensures that the adjustment is accurate and fast, avoiding the deviation of the filling amount caused by improper adjustment. When replacing filling rods, the modular structure enables the old filling rod to be removed and the new one to be installed quickly, without the need for complex disassembly and assembly of the entire filling unit. This function (Patent No.: ZL 2015 2 1021519.4) greatly improves the flexibility and adaptability of the equipment, allowing it to quickly switch between different production tasks and meet the needs of multi - variety and small - batch production in the pharmaceutical industry.
5. Effective Capsule Locking and Mold Hole Cleaning Function
5.1 Mold Hole Cleaning to Ensure Capsule Separation
During the production process, some powders (especially those with strong hygroscopicity) are prone to absorbing moisture in the air and sticking to the inner walls of the upper and lower mold holes. If the stuck powder is not cleaned in time, it will block the mold holes, causing capsules to fail to separate normally from the mold holes. This not only leads to unqualified capsules but also may cause jamming of the equipment, affecting the continuity of production. The NJP-1200D's die hole cleaning device uses purified compressed air and intermittent gas impingement technology to solve this problem. Purified compressed air ensures that no impurities are introduced into the mold holes during cleaning, avoiding pollution to the capsules. Intermittent gas impingement means that the device sprays compressed air into the mold holes at regular intervals, which can effectively blow off the powder stuck to the inner walls of the mold holes without damaging the mold holes. This function ensures that the mold holes remain clean at all times, greatly reducing the probability of capsule separation failure and effectively increasing the rate of qualified capsule loading.
5.2 Flexible Capsule Locking Adjustment
The capsule locking machine of the NJP-1200D is equipped with a flexible adjustable slot - lock capsule plate. The capsule locking process is a critical step in ensuring the quality of finished capsules; if the capsules are not locked in place, they may open during transportation or storage, leading to powder leakage. Traditional capsule locking devices often require adjusting the station lever to correct the locking position when capsules are not locked properly, which is time - consuming and may affect the stability of the entire production line. The slot - lock capsule plate of the NJP-1200D can be fine - tuned at any time when capsules are not locked in place, without the need to adjust the station lever. This adjustment is simple and fast, and can be completed by operators without stopping production. It ensures that each capsule is locked tightly and firmly, improving the quality stability of finished capsules and reducing the risk of powder leakage in subsequent links.
6. Stable and Quiet Transmission Function
The transmission system is the "power heart" of the NJP-1200D, and its performance directly affects the overall stability and noise level of the equipment. The NJP-1200D adopts the latest CAM drive system, with a transmission bracket designed for up - and - down movement. Unlike traditional external CAMs used in many capsule filling machines, all operating CAMs of the NJP-1200D use inner groove CAMs. External CAMs are prone to friction and wear with other parts during high - speed operation, leading to increased noise, reduced precision, and shortened service life. Inner groove CAMs, on the other hand, have a more stable structure. The contact area between the CAM and the follower is larger, and the force is more uniform, which reduces friction and wear during operation. This design enables the NJP-1200D to operate with finesse, accuracy, stability, and no noise even at high speeds. The stable transmission function ensures that each moving part of the equipment (such as the turntable, filling unit, and capsule locking machine) coordinates with high precision, avoiding errors caused by transmission instability. The low - noise operation also creates a better working environment for operators, complying with the requirements of modern industrial production for a comfortable working environment.
7. Gentle and Dust - Free Finished Product Discharging Function
The finished product discharging link is the last step of capsule filling, and its quality directly affects the integrity and cleanliness of the finished capsules. The NJP-1200D's new - type finished product capsule discharging mechanism exclusively adopts a capsule clamping plate design, which has two outstanding effects. First, it does not require an external air source during discharging. Traditional air - driven discharging mechanisms often generate air flow during operation, which can blow up the powder attached to the surface of the finished capsules, causing dust to fly in the production workshop. This not only pollutes the workshop environment but also may cause cross - contamination between different batches of products. The capsule clamping plate design of the NJP-1200D uses a mechanical clamping method to take out the finished capsules from the mold holes, avoiding the use of external air sources and thus eliminating dust flying during production. Second, this design effectively avoids mechanical injury to the finished capsules. The capsule clamping plate is made of high - quality materials with a smooth surface, and the clamping force is precisely controlled. When clamping the capsules, it can firmly hold the capsules without applying excessive force that would cause deformation or damage to the capsule shells. This ensures that the finished capsules have a complete appearance and intact structure, meeting the strict quality requirements of the pharmaceutical industry for finished products.
8. Efficient Powder Recycling and Automatic Lubrication Function
8.1 Powder Recycling to Prevent Cross - Contamination
The NJP-1200D is equipped with a dedicated powder reclaimer, which is responsible for recycling the powder leaked from the filling base and the powder collected by the integrated powder aspirator. A key advantage of this function is that it can separate the recycled powder from the waste capsules, preventing cross - contamination between the powder and the waste capsules. Waste capsules may carry impurities or microorganisms, and if they are mixed with the recycled powder, the powder will be contaminated and cannot be reused. The powder reclaimer uses a special separation structure to separate the powder from the waste capsules effectively. The separated powder meets the production quality standards and can be directly re - input into the machine for production without additional disinfection procedures. This function not only further reduces powder waste but also ensures the safety and quality of the recycled powder, avoiding the risk of product contamination caused by recycled materials.
8.2 Automatic Lubrication to Extend Equipment Life
The transmission mechanism of the NJP-1200D is equipped with an automatic fuel supply system, which realizes timed, quantitative, and fixed - point automatic oil supply. In traditional equipment, lubrication of the transmission mechanism requires manual operation. Operators need to regularly add lubricating oil to the designated parts, which is not only time - consuming and labor - intensive but also prone to problems such as insufficient lubrication (due to missed additions) or excessive lubrication (due to incorrect dosage). Insufficient lubrication will increase the friction between the transmission parts, leading to accelerated wear and shortened service life of the parts; excessive lubrication will cause oil leakage, which may pollute the powder and capsules. The automatic fuel supply system of the NJP-1200D solves these problems. It is preset with a scientific lubrication program, which adds the correct amount of lubricating oil to the designated parts of the transmission mechanism at fixed intervals. This ensures that the transmission mechanism is always in an optimal lubrication state, reducing the wear of accessories, extending the service life of the entire equipment, and reducing the frequency of equipment maintenance and replacement of parts.
