The correct development path of the tablet press industry
Installation and Adjustment of Rotary Tablet Press Mold
Before installing the mold of the rotary , the power supply of the must be cut off, and the cover plate-lower punch and upper rail-hopper-feeder must be removed. Open the right door and gradually clean the working surface of the turntable, the die hole and the die for installation, and apply some vegetable oil on the middle die and the punch, and adjust the thickness of the sheet to a position above 5.
How to install the disc
Rotate the installation of the middle mold of the , loosen the embossing screw screwed on the cover plate of the upper track, pull out the cover plate, and lightly hit the middle mold from the punching hole with the middle mold stick to make the middle mold fit into the middle mold hole. The middle mold must not be higher than the working surface of the turntable, and should be checked one by one to avoid mistakes. When installing the middle mold, you can turn the test hand wheel inside the lower part of the machine to make the turntable rotate clockwise, and then fix it with the middle mold screw.
For the installation of the upper punch of the rotary , remove the cover plate on the guide plate of the upper rail, then gradually insert the upper punch into the hole, rotate the punch with the thumb and forefinger, and check that the head enters the middle die and slides up and down flexibly. No hard rubbing phenomenon is qualified. After all the upper punches are installed, fasten the cover.
For the installation of the lower punch of the , remove the upper rail of the lower punch. The installation method is the same as that of the upper punch. After installation, install the upper rail of the lower punch and fasten it with screws. (Note that the outer circle must be positioned close to the middle plate when the lower punching upper rail is installed)
After the complete mold is installed, turn the handwheel to make the turntable rotate for two circles, and observe the upper and lower punches entering the middle die hole and running on the rail guide. It should be flexible, without collision and hard rubbing. It should be noted that when the lower punch rises to the highest point (that is, the place where the film is released), it should be 0.05-0.15 higher than the working surface of the turntable to avoid damage to the punch and other parts.
Installation of special-shaped molds for tablet presses (triangle-ellipse-rectangle and other geometric shapes are called special-shaped)
Install the guide flat key on the upper punch first, and fasten it with screws.
The upper punch and the middle die of the rotary must be installed synchronously. Press the guide key to insert the upper punch into the upper punch hole. The upper and lower East China are flexible, and there is no hard rubbing phenomenon. Then lift the upper punch and put on the middle mold. Let the head of the upper punch enter the hole of the middle die, align the middle die with the die hole, place it flat, tap the tail of the upper punch lightly with a hammer, and drive the middle die. After the middle die enters the die hole, it is qualified if its plane cannot exceed the working surface of the turntable. Then tighten the screws of the middle mold, check that the head of the punch enters the middle mold and slides up and down flexibly, and it is qualified if there is no collision and hard rubbing.
The installation of the lower punch of the rotary . Remove the lower punch upper rail and install the lower punch rod. Check that the head of the lower punch enters the middle mold and moves up and down. It should be flexible, without collision and hard rubbing. After installing all the lower punches, install the upper rail of the lower punch and fasten them with screws. (Note that the outer circle must be positioned close to the middle plate when the lower punching upper rail is installed)
After the whole set of middle mold is installed, turn the hand wheel to make the turntable rotate for 2-3 circles. Observe that the upper and lower punches enter the middle die hole and run flexibly on the upper and lower guide rails, without collision and hard rubbing. Note that when the lower punch rises to the highest voltage (that is, the place where the film is released), it should be 0.05-0.15 mm higher than the plane of the turntable. Then start the motor, idle for 5-10 minutes, and put it into normal production after the operation is stable and there is no abnormal phenomenon.
