During the tableting process, the pressing part 5 gradually approaches the pole piece. When the abutment 14 contacts the sliding block 13, the sliding block 3 15 moves downward due to the push of the abutment 14, compressing the spring member 16. As the pressing part 5 continues to descend, the sliding block 4 also gradually moves downward and finally abuts against the pressure sensor 17. When the pressure sensor 17 is subjected to sufficient pressure, it triggers a signal and transmits the signal to the controller 8. After receiving the signal, the controller 8 immediately stops the operation of the hydraulic cylinder device 16, thereby accurately controlling the stop position of the pressing part 5. This step ensures the accuracy and reliability of the tableting operation and avoids excessive tableting or misoperation.
