three-layer tablet pressThe punch rod needs to be accurately positioned with the intermediate die to install the special-shaped die. Tighten the punch rod again in the middle die hole to avoid inaccurate positioning. After the mold is installed, rotate it several times with the hand plate, and it can be moved without special conditions. If the tablet is pressed out with a three-layer tablet press, the tablet will crack and the hardness will be uncoordinated, mainly because the material, material density, dry humidity, etc. are not properly adjusted after discharging.
The pressure of the three-layer tablet press needs to be adjusted appropriately. If the pressure of the first filling is not properly adjusted, the hardness of the lower half of the tablet will alternately become hard and soft. The second filling is done again by the pressure of the tablet, so the pressure adjustment determines the size of the tablet.
If the three-layer tablet press presses the flat plate into a special-shaped mold, the mold has certain positioning requirements, such as square, triangular, oval and other shapes. The punch on the turntable of the three-layer tablet press requires the structure of the tablet press. Since the punch needs a direction key to cooperate with the punch on the turntable during the installation process, the requirements for the mold are increased. The lower punch of the three-layer tablet press does not leave the middle die hole during the working process, and no other processing is required. The punch of the special-shaped plate cannot rotate freely, but can only move up and down on the guide rail. In the process of rotary drive, the pull rod and the guide rail slide friction, so that the pull rod and the guide rail wear each other. Therefore, when we use the three-layer tablet press, we should pay attention to lubrication, remember to do a good job in daily work, and regularly check for looseness or wear. Stamping machines and dies cannot operate and produce due to impact.
Special-shaped mold enterprises can only pass the installation after we accurately position the punch and the middle die of the three-layer tablet press, and then tighten the punch on the middle die hole to avoid inaccurate market positioning. After all the mold design and installation is completed, rotate the hand plate several times, and the operation can be completed without special analysis.
