    When the reed screw is loose,you should tighten it.

    When the capsule shells are arranged in the working board,if the mouth is higher or lower,you should adjust the height of the dislocation plate and guide rail.


    When the capsule shells fall down too much,maybe the reason is that the vibration isn’t adjusted properly,you should adjust the vibration.The other reason is that the size of capsule shells is substandard,you should choose eligible capsule shells.

    When the capsules are stuck on the board and cannot fall down,you should change the capsule shells or you should adjust the position of dislocation plate and table plate holes.

    When the mold cannot be reset in the track, and the guide rail rear end compression spring or the capsule variants is stuck. You should reinstall the spring or push rod ,and push the capsules down with a stick.

    When the guide plate of the mold is worn,which results in the low capsule fitting rate,you should change a new mold.

    In a word,these are general problems when using capsule filling machines.If there are other problems,you can repair the machines according to the real situations.
