At the same time, the lifting cylinder 104 of the cup support assembly drives the cup support fixing plate 102 upward, thereby driving the cup support 103 upward. The cup support 103 moves upward together with the cup body on the chain plate. When the punch fixing plate 302 is in the downward process, the cup pressure cover 313 first contacts the cup body. When it continues to descend, the cup pressure cover 313 does not move, and the punch 310 continues to descend. The cup pressing cover 313 fixes the cup body under the reaction of the compression of the spring 312, and the punch 310 continues to move downward to punch. After the punching action is completed, the lifting cylinder 104 of the cup support assembly moves downward and resets, driving the cup support fixing plate 102 to move downward and separate the cup support 103 thereon from the cup body. The lifting servo motor 303 drives the punch fixing plate 302 upward. Under the spring force of the spring 312, the cup pressing cover 313 separates the cup body from the punch 310.
