[0003] Currently, the same equipment is being used to produce multiple sizes of ampoules, and the differences in bottle shape between sizes are quite significant. Previously, the maximum difference was within 30 or 40 mm. Currently, the difference has reached approximately 60 mm. The previous design relied on sliding upper and lower blades to adjust the size, which was complex and time-consuming. Furthermore, as shown in Figure 1a, when producing long ampoules, the short lower blade only protruded from the mounting plate by a distance h of 1.44 mm. However, as shown in Figure 1b, when producing medium ampoules, the medium lower blade protruded by a distance h of 40.44 mm. And when producing short ampoules, as shown in Figure 1c, the long lower blade protruded by a distance h of 58.44 mm. That is to say, the shorter the ampoule, the longer the distance of the hollow part on the mounting plate. During the die cutting process, under the action of high pressure, since the bottom of the lower blade plate is hollow and is locked by only three screws, a large area of ​​sinking will occur, that is, the strength is insufficient and the cutting edge is unstable.
