The elastic retaining ring 101 is manually nested on the material tower 15, the material tower assembly 1 is arranged vertically, and the elastic retaining ring 101 is blanked by its own gravity. In order to ensure smooth blanking without jamming, the material tower assembly 1 further includes a counterweight block 18 that slides with the material tower 15 and the positioning key bar 14 and presses the elastic retaining ring.

In this embodiment, the positioning key bar 14 and the material tower 15 are of separate structures, which are fixed together by bolts. Of course, those skilled in the art can understand that it is also feasible to adopt an integrated structure.

The positioning key bar 1 is used for positioning the elastic retaining ring 101 in the direction. The cylinder feeding assembly 2 is horizontally fed, that is, the material channel extends horizontally, and the elastic retaining ring 101 is transported from the back to the front, so the positioning key bar 14 is provided on the rear side of the material tower 15 here.
