It passes through the adjustment plate 3 and the mounting seat 4 and is tightened by a nut with threaded matching to adjust the relative distance between the adjustment plate 3 and the mounting seat 4, thereby changing the effective working stroke of the linear drive 2. The elastic member 63 can be a spring or a rubber sleeve; the linear drive 2 drives the adjustment plate 3, the mounting seat 4 and the vacuum distributor 5 to move vertically up and down synchronously, and the setting of the shaft sleeve 61 and the guide shaft 62 ensures that the vertical up and down movement is well guided and supported to avoid shaking or deviation. At the same time, since the elastic member 63 and the guide shaft 62 are exposed to the outside, they are easy to clean, which can effectively reduce the adhesion of the powder to the elastic member 63 and the guide shaft 62, and improve the stability of the capsule separation operation; when it needs to be disassembled for cleaning or replacement, it is only necessary to remove the bolts used to connect the adjustment plate 3 and the end of the movable shaft of the linear drive 2, and remove the upper structure as a whole, so that the elastic member 63 or the guide shaft 62 can be cleaned or replaced without removing the shaft sleeve 61, which is convenient for disassembly and assembly.
