By making the top of the rotating drum 12 and the bottom of the hydraulic cylinder 1 piston rod fit together, the stability of the rotating drum 12 during use can be improved. By providing a rotating handle 11 fixed to the outer wall of the rotating drum 12 above the connecting plate 6, the rotating handle 11 can be used to facilitate the rotation of the rotating drum 12 by the staff. By providing a limiting block 17 fixed to the bottom of the rotating shaft 15 at the bottom of the rotating drum 12, and a limiting groove 16 matching the limiting block 17 at the bottom of the connecting groove 7, the limiting groove 16 and the limiting block 17 can limit the staff when reinstalling the tabletting mechanism 3 on the device. By making the cover plate 18 and the connecting plate 6 an integral structure, the stability of the device during use can be improved.

By providing the hollow pressing plate and the pressing seat, cooperating with the oil inlet pipe and the oil outlet pipe, the heat conducting oil at a certain temperature is introduced into the interior of the pressing plate and the pressing seat and circulated, thereby meeting the tabletting temperature requirement of the molecular sieve desiccant, which can heat the tabletting mechanism 3 and the pressing table 9 and keep their temperature constant.

[0024] Combining the drawings Figures 1-5The method of using this utility model is as follows: The tableting mechanism 3 and the pressure table 9 are heated and kept at a constant temperature. Then, the raw material is placed into the pressure groove on the pressure seat. The hydraulic cylinder 1 is then opened, causing its piston rod to extend. This causes the rotating drum 12 to move towards the pressure seat under the drive of the hydraulic cylinder 1. The connecting plate 6 also moves towards the pressure seat via the threaded groove 10 and the movable block 13, thereby driving the tableting mechanism 3 to move towards the pressure seat. This allows the pressure block inside the tableting mechanism 3 to enter the pressure groove, thus pressing the raw material into shape. When the operator needs to repair or replace the tableting mechanism 3, the connecting plate 6 is kept in place... The cylinder remains stationary, and the rotating handle 11 drives the rotating drum 12 to rotate forward within the connecting plate 6 and on the rotating shaft 15, causing the threaded groove 10 to rotate within the connecting plate 6. At this time, because the two movable blocks 13 are respectively in contact with the bottom of the cover plate 18 and the bottom of the connecting groove 7, the movable blocks 13 will not rotate with the rotating drum 12 and the threaded groove 10. Instead, they will move closer together under the rotational drive of the threaded groove 10, thus removing the two movable blocks 13 from contact with the bottom of the cover plate 18 and the bottom of the connecting groove 7. At this point, the two movable blocks 13 will rotate under the influence of the threaded groove 10 and the rotating drum 12, aligning with the through hole 8. Then, by controlling the connecting plate 6 to move downwards, the two movable plates... The rotating cylinder 12 is disengaged from the bottom of the connecting groove 7 through the through hole 8, and the limiting block 17 is disengaged from the rotating shaft 16. This removes the rotating cylinder 12 and the movable block 13 from the connecting plate 6, allowing the operator to remove the damaged tableting mechanism 3 from the device for repair or replacement. Then, by controlling the repaired or new tableting mechanism 3 to move towards the hydraulic cylinder 1, the two movable blocks 13 on the rotating cylinder 12 can enter through the through hole 8 on the cover plate 18 between the cover plate 18 and the bottom of the connecting groove 7, allowing the rotating cylinder 12 to re-enter the connecting plate 6, and the limiting block 17 to re-extend into the shaft 16. Inside the rotating shaft 16, the connecting plate 6 is kept stationary, and the rotating cylinder 12 is driven to rotate in the opposite direction to the rotating shaft 15 inside the connecting plate 6 by rotating the handle 11. This causes the threaded groove 10 and the movable block 13 to rotate inside the connecting plate 6, so that the movable block 13 contacts the limiting rod 14. Because the movable block 13 contacts the limiting rod 14, the movable block 13 can no longer rotate under the drive of the rotating cylinder 12 and the threaded groove 10. Instead, it will be driven by the threaded groove 10 to move the two movable blocks 13 away from each other, so that the two movable blocks 13 re-abut against the bottom of the cover plate 18 and the bottom of the connecting groove 7 respectively, thereby fixing the tablet pressing mechanism 3 and the rotating cylinder 12 together.
