In such a conventional configuration, when cleaning the entire rotary powder compression molding machine or replacing the worn dustproof seal 6, it is necessary to tighten and loosen the bolts 8 when disassembling and assembling the lower punch dustproof device. It was a hassle and took a lot of time. In particular, when assembling, if the centers of the lower punch sliding hole 3a and the lower punch through hole 4 are misaligned, the dustproof effect will be impaired. Since positioning work is required, a lot of effort is required for assembly. However, despite this effort, due to the dimensional difference between the diameter of the bolt 8 and the bolt through hole provided in the seal retaining plate 5, and due to the rotational force accompanying the tightening force of the bolt 8. Therefore, the seal presser plate 5 is easily displaced. For this reason, there is a problem in that the lower punch sliding hole 3a, the lower punch through hole 4, and the dustproof seal 6 may be assembled with their respective centers shifted from each other. Furthermore, during cleaning, it is very troublesome to remove dust that has entered the screw hole 9 when the seal presser plate 5 is removed.

Therefore, in the dust-proof device for the lower punch of a rotary powder compression molding machine according to the present invention, a plurality of stoppers each having a presser portion facing the upper surface are attached to the upper surface of the lower punch mounting portion of the rotary plate through which the lower punch is inserted. At the same time, at both ends of the seal presser plate, which has a plurality of holes for the lower punch,
An engaging portion that engages with the stopper is formed, respectively.
Then, insert and remove the seal holding plate fitted with a rubber dust-proof seal for dustproofing the lower punch into the lower punch through hole in the radial direction of the rotary disk along the upper surface of the lower punch attachment part. By making it possible, the above objective is achieved.

To assemble the device of the present invention, first fit a plurality of dustproof seals into the lower punch through holes of the seal retainer plate, and then rotate the seal retainer plate from the outside of the rotary disk along the upper surface of the lower punch attachment part. Insert it toward the center of the board. Insertion of the seal mounting plate is stopped when the engaging portions at both ends thereof engage with the stoppers, respectively. Thereby, the dustproof seal and the lower punch sliding hole are roughly positioned. Finally, the lower punch is inserted upward into the lower punch sliding hole of the rotary disk, and the upper part thereof is inserted through the dustproof seal. Then, the dustproof seal will be accurately self-aligned to be concentric with the lower punch. If the dustproof seal is immovably fitted into the lower punch through hole, this self-alignment is performed with the movement of the seal presser plate, and
If the dustproof seal is movably fitted into the lower punch through hole, only the dustproof seal follows the lower punch without moving the seal presser plate. In the manner described above, the lower punch dustproof device can be assembled without the need for bolting.
In this assembled state, upward movement of the seal presser plate is prevented by the presser portion of the stopper, and outward movement of the seal presser plate is prevented by the lower punch. Further, the lower punch dustproof device can be disassembled by performing the assembly procedure in reverse order as described above.

First, a plurality of dustproof seals 20 are respectively fitted and held in the lower punch through holes 22 of the seal holding plate 19, and then the seal holding plate 19 is rotated from the outside of the rotary disk 11 along the upper surface of the lower punch mounting portion 14. Board 1
Insert it toward the center of 1. Insertion of the seal mounting plate 19 is stopped when the engaging portions 23 at both ends of the seal mounting plate 19 engage with the stoppers 18, respectively.
Thereby, the dustproof seal 20 and the lower punch sliding hole 16
and are roughly positioned. In this state, the seal presser plate 19 is not fixed to the upper surface of the lower punch attachment portion 14, but is in a state in which it can move along this upper surface. Finally, the lower punch 17 is inserted upward into the lower punch sliding hole 16 of the rotary disk 11, and its upper part is inserted through the dustproof seal 20. By this insertion, the dustproof seal 20 is moved to be concentric with the lower punch 17 together with the unfixed seal presser plate 19, and is accurately self-aligned.
