1.What is a capsule filling machine?
Full-automatic capsule filling machine fills powder, particles and tablet materials into empty capsules. The professional capsule filling machine conducts filling through stopples, batches and frequency control. It is suitable for automatically filling, separating, (eliminating wasted contents) sealing up the powder or particle drugs to finished products. Our factory indigenously developed this filling device according to the advantages of similar devices at home and broad, as well as the practical national conditions. The production process is completely in conformity with GMP regulations.

2.Working principle of the capsule filling machine
When the device is operating,
In Station 1 and Station2  , the capsule bucket inserts the capsules vertically into the baffle one by one. The horizontal fork pushes them to the external end of correction block. Then, the vertical fork absorbs them to the module holes, separates the head from the body. 

In Station3, upper module declines to lower module and moves externally
In Station 4, as for powder filling, powder in the chamber is compressed for five times into the capsules. 

Station 5 is reserved for expansion. Pellet device is installed to contain the sustained-release pellets.
Station 6 can eliminate and absorb the defective capsules through the dust suction pipelines. 

In Station 7, the upper module moves downward. Lower module moves inward.
In Station 8, the lockup rod rises to seal the filled capsules.

In station 9, the sealed capsules are ready to be collected.
In station 10, the vacuum cleaner hole is cleaned for the next cycle. 
activation and operation of machine

3. connect to general power
Before activating the machine, check the device and rotate the main motor shaft. Operate the machine for 1 to 3 cycles, and turn the battery main switch from “OFF” to “ON”

3.1 status selection 
Machine operation includes manual mode and automatic model. Manual mode is used in a test run. When debugging the machine, switch to manual mode. After the machine operates normally, turn the function switch to “automatic operation”. at this point, main motor and feeding motor are in automatic mode. The feeding motor is controlled by the powder sensor. 

3.2 machine operation
In the manual status, press the “vacuum pump working” button. The indicator lights up, vacuum pump and electric motor are activated. Electric motor and feeding motor are in the inching mode. For the automatic status, press the “vacuum pump working” button, and then the “main motor working” button. The machine starts to operates normally.

3.3  emergency use
For immediate halt, press the emergency button to halt the machine right away. For restart, switch the button according to the arrow to activate self-locking emergency button. Then, press”vacuum pump working” and “main motor working” buttons. The machine starts operating again. 

3.4 usage of door control switch
Door control switches are installed on four edges of glass doors. If a door is open or not tightly closed, the buzzer gives out alarm. In automatic mode, the machine can not be activated. If four doors are closed, the machine can work normally

3.5  automatic control of feeding
Dosage of medicine chamber is controlled by capacitance-type sensor. According to instructions in “5.2.8”, adjust the height of sensor. If drug material is lower than the preset height, it can automatically start the motor. If drug material reaches the preset height, the feeding motor automatically stop activating the motor. When drug material is used up in the funnel, the machine automatically halts the main motor through incomplete filling and delaying.

4. machine maintenance and cleaning
After the machine operates for a long period of time, regularly clean the spare parts that are in contact with drug powder. Cleaning is also needed for changing powder or not using the machine for long periods 
Greasy dirt under the transmission parts should be cleaned frequently to observe the operation clearly. 
Filter of the vacuum system should be opened regularly to clean up the dirt and sewage.

4.1 machine lubrication
a)working surface of roller wheels should be coated with lubricating grease weekly
b)Knuckle bearings of connecting rods should be coated with oil lubrication weekly. 
c)The bearings should be cleaned with lubricating grease on a regular basis. Sealed bearings can be coated with oil lubrication. 
d)Transmission chain should be checked and coated with lubricating oil weekly.
e)Oil amount of main transmission and feeding reducers should be checked monthly. Lubricating oil should be replaced every half year. 
f)Scale division boxes under the dose plate and turntables should be dismantled and maintained with the help of professionals
g)460After the scale division boxes operate for 1000 hours, lubricating oil needs to be changed for the first time. Afterwards, the lubricating oil should be replaced when the machine operates for every 3000 hours. 
h)On a weekly basis, the cover plate should be taken off the rotary disk. motor points and bearings between T-shaped axis and guide rod should be coated with oil. For every 1000 hours of machine operation,T-shaped axis and seal ring should be dismantled for overall cleaning, replacement and oil lubrication. 

4.2 Common fault removal

The device is installed with dual pipes for dust and powder suction(Refer to the figure). One of the pipelines is for cleaning the nodule holes. The other pipeline is for recycling the powder in the filling part. The airflow suction pipeline is also installed with powder recycler, consisting of gas and powder separation block, as well as powder bucket. The pipeline can directly recycle some of the lost materials from the filling process. 
Due to the suction of vacuum cleaner, the lost materials are recycled by the exclusive powder pipelines. Due to gas and powder separation blocks, 80-90% of powder accumulates in the bucket. The gas is sucked into the vacuum cleaner and filtered through the pipeline(Notes: gaps between the separation blades can be adjusted according to the particle size of powder. The adjustment method is: Loosen the fixated bolts on the blades. Move the blades upward and downward. Then, screw up the bolts appropriately). 
Powder bucket is installed with observation mirror. If powder is higher than the observation mirror, tear apart the fixed buttons. Then, add the drug powder (no need for sterilization or disinfection) directly to the material funnel of the automatic capsule filling machine for subsequent filling.
