Customer Reviews
 I would like to thank you for all your efforts to choose the correct atomizer for our spray dryer,High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.


I really don't know how to thank you, you are my angel, Thank you very much. Super Fine Pulverizing this one is faster than other same power machine and is easy to operate and repaired.

Brief introduction of main components of automatic capsule filling machine

1. Sowing mechanism:
This mechanism is used to insert hollow capsules from the hopper into the seeding tube. A reed switch is set below the seeding tube. When the seeding tube is driven down by a sector gear, the switch releases a row of capsules (7 capsules in a row of 1 #, 2 #, 3 # and 6 capsules in a row of 0 #) under the action of a collision iron. When the seeding tube rises upward, the switch immediately closes the seeding tube.
The capsule that has fallen under the capsule comb is pushed forward to the turning position by the capsule pushing plate. The pressurized capsule head pushes down and turns around at the same time (the body faces down and the cap faces up). There is a negative pressure airflow below the mold. When the pressurized capsule head pushes down and leaves the capsule comb, the capsule is sucked into the mold by the airflow in the mold hole. Because there is a small step in the mold hole that prevents the capsule cap from remaining in the upper mold, the capsule body continues to slide into the lower mold space under the vacuum, From this mechanism, the capsules are arranged, turned and separated.

The mechanism is driven by a separate motor to run the cam, rocker and ratchet mechanism. Every time the cam rotates, the ratchet pushes a tooth (that is, a row of holes are pushed by a mold), and the cam drives the rocker to make the sector gear run for a cycle. The mechanism is equipped with automatic counting control. When the mold is full of capsules, the mechanism will stop automatically. If it needs to stop midway, it can also stop manually. The speed of the machine is adjusted by the converter knob and key on the console, and the speed is displayed by an instrument.

In case of failure to separate some capsules, the mold can be rotated 2~3 times by hand to facilitate its separation under vacuum adsorption.
The machine is delivered with a set of moulds, and another set will be purchased by the user according to the accessories catalog.
Difference: each row of 0 # device has 6 holes, and capsule mold has 6 × 60=360 holes, the thimble disc is 360 thimbles, and the corresponding capsule pressing head, capsule pushing plate, capsule comb, switch, and head turner are all 6 rows.

1 #, 2 # and 3 # devices have 7 holes in each row, and the capsule mold has 7 × 60=420 holes, the thimble disc is also 420 thimbles, and the corresponding accessories are all 7 rows.
Replacement: 6 capsules 0 # and 7 capsules 1 #, 2 # and 3 # should be replaced if different models of capsules are used. If it is found that there is one more capsule or one less capsule sent from the turning groove, J wrench or pointed nozzle can be used for the adjustment shown. Adjust the position of the capsule pushing plate. Loosen its connecting screws first, then move the capsule pushing plate until the cutting edge of the capsule head is just pressed on half of the total length of the capsule, and then tighten the connecting screws

2. Filling structure:
The function of this mechanism is to automatically load the drug into the empty capsule in the capsule mold in sequence. The hopper is equipped with a stepless speed regulating motor (the speed displayed by the instrument), which drives the propeller to force the drug into the empty capsule. The lower rotary table drives the mold to rotate. The lower rotary table also drives the mold to run with the stepless speed regulating motor, making the mold run under the feeding nozzle for a week. The mold is controlled by photoelectric counting (the counter is set 30 times). When the filling (ON) is pressed to start, the hopper is pushed to the mold by the air cylinder. After the hopper is in place, the rotary table motor and the hopper motor start automatically. When the die rotates for one circle, it automatically stops, and the cylinder automatically returns to its original position.

If the speed of the hopper is too fast or too slow, adjust the two one-way throttle valves at the interface of the solenoid valve to make the speed appropriate. In addition, if the motor starts before the hopper is in place, or fails to start after it is in place, the time relay on the computer control board can be adjusted to start within 1 second after it is in place. The speed of the hopper motor and the speed of the rotary table motor can be adjusted depending on the amount of filling and the good or bad fluidity of the medicine. If the medicine is difficult to be filled, the counter setting value can be adjusted to 60 or 90, and the factory setting is 30.

3. Locking mechanism:
This mechanism is used to lock the capsule (upper and lower molds are combined) that has been filled with medicine, and make the capsule top cylinder act through the foot valve. Then, it is used to push the capsule mold, make the thimble reset, push the capsule out, and flow into the capsule collecting box.

4. Air control system:
The pressure used by the system is 0.4~0.7MPa. The compressed air sent by the air pump (see the table below for the parameters of the supporting air compressor) is sent to the foot valve and solenoid valve after being processed by the triplet.

4.1. Triple parts * step is air filtration; The second step is voltage regulation; In the third step, the vaporized oil is supplied to the air circuit system for lubrication, and the fuel injection regulation is generally to spray a drop of oil (ordinary engine oil) within 1~3 minutes.

4.2 The foot valve controls the action of the locking cylinder. When the foot is lowered, the locking cylinder is pushed out to lock the capsule. When the foot is released, the cylinder piston retracts.

4.3 The solenoid valve is commanded by the electrical system, which controls the action of the filling hopper. The outlet of the solenoid valve is equipped with two one-way throttle valves to control the operating speed of the cylinder.
