The lubrication of the friction surface of the moving parts is an important step to ensure the normal operation of the machine and extend the service life of the main moving parts. If the main machine parts operate in the condition of lack of oil, they will be damaged quickly and can not be put into operation. Therefore, before you use the tablet press, all the oil cups, oil holes and friction surfaces must be coated with lubricating oil. Then set the machine running to make all the friction surfaces covered with oil. After it’s done the machine can be put into use. From time to time, do this per shift, but not too much refilling each time, so as to avoid spillover, which may affect the hygiene and contaminate the tablets.
Before each shift, the user must make sure that the screws are not loose. Regular checks are required during operation. Screws should be kept fastened all the time to avoid malfunction. The main parts are: the fastening nuts of upper punch, the fixed screws of the middle die, the fixed screws of the lower punch; the nuts of the connecting rod, the screws of the connecting rod; lifting locknut (2 pieces) butterfly screws; fixed screws of the middle die station (2 pieces).
Before each shift and after each shift, it is required that the user should make a few tablets by hand for testing. If nothing goes wrong, it is safe to switch to the electric mode.
In the tabletting process, the user must frequently inspect the quality of the punch dies. If defects such as cracks, chipped edge and deformation are found, the punch dies should be replaced in time, so as to avoid damage to the machine and affect the quality of the tablet.
The remaining particles or powder should be removed after daily use, and all parts of the machine should be wiped clean. If the machine is left unused for a long time, the punch die should be disassembled, and the friction surface and the working surface of the machine should be cleaned and coated with anti-rust oil. The whole machine should be wrapped by the dust-proof cover. After being wiped clean, the punch die should be preserved in the oil. It’s recommended that there should be a tooling box specially for keeping the punch dies to prolong its service life. The tablet press requires at least two inspections per month.
