Main Factors Affecting The Production Quality Of Automatic Capsule Filling Machine

There are many factors that affect the quality of the automatic capsule filling machine, among which the powder filling mechanism and the positions of the capsule turret are important factors. In the aspect of powder filling mechanism, the powder filling mechanism is mainly composed of 6 equal parts of intermittent rotary movement metering plate, 6 groups of axial movement punch rod (adjustable axial position) and powder screw automatic feeder. There are 6 groups of cylindrical holes (measuring bin) with the corresponding hole diameter of the capsule number on the rotary metering disk, which are arranged symmetrically in the center. The dimensional tolerance, position tolerance, precision and finish of the cylindrical hole all affect the capsule loading.

In addition, the sixth position of the automatic capsule filling machine is to press the powder column which has been created in the measuring bin of the measuring disk into the capsule of the fifth position of the capsule turret with the full number of B mold base by the hard punching rod. Therefore, the installation correctness and synchronization of the machine will directly affect the filling quality of the capsule.

In terms of each working position of the capsule turret, it often appears that the capsule does not enter the capsule mold base in the direction of vertical fork movement, or the capsule enters the a-head mold base but the capsule a and B heads are not all separated, which will also affect the quality of the capsule to a certain extent.

In addition, the factors that affect the quality of automatic capsule filling machine also include the occurrence of some common faults. If these faults are not handled in time, the quality of the equipment will also be affected. According to the summary of relevant manufacturers, the common failures are that the capsule does not fall smoothly in the capsule slide, the outer diameter of some capsules is too large or there is foreign matter blocking.

At this time, the capsule filling machine needs to replace the qualified capsules and take out the foreign matters with tools. In addition, the operator should pay attention to that the discharging capsule cannot enter into the hole of the capsule plate, the opening and closing time of the clamping spring should be appropriate, and the position of the pushing and pressing claws should be confirmed.

If the vacuum tube is not sealed tightly or the vacuum degree fails to meet the requirements, the waste capsule can be removed and the foreign matters can be cleaned; the top pole position can be adjusted and the position of the bag can be tightened; the filter can be cleaned, the vacuum system can be checked and the gauge pressure can be adjusted. If the clutch is overloaded, it is likely that the friction between the metering plate and the sealing ring is too large due to the wet powder; the friction between the filling rod and the metering hole is too large due to the misalignment; the gap between the metering plate and the sealing ring is improper.

The automatic capsule filling machine is an important equipment for the production of capsules. If there is a problem in the quality of the equipment, the capsule products will also be affected. Therefore, in order to ensure the safety of capsule production, in this part of equipment, operators and equipment manufacturers should deal with the factors that affect the quality of automatic capsule filling machine.
