The stripper plate 6 is provided with stop blocks 94 on one side of the slide plate 71, which is away from the electric cylinder 75, the stop blocks 94 are in one-to-one correspondence with the two ends of the slide plate 71, and when the slide plate 71 is abutted against the stop blocks 94, the two belts 74 just clamp the condom, and a space exists between the pneumatic finger 9 and the head of the condom.

During discharging, the electric cylinder 75 drives the sliding plate 71 to move forward to a position abutting against the stop block 94, the driving rod of the electric cylinder 75 continues to move forward, and the driving rod of the electric cylinder 75 overcomes the elastic force of the limiting spring 93 to drive the pneumatic finger 9 to move forward, so that the condom head falls between the two clamping jaws of the pneumatic finger 9, in the process, the distance between the pneumatic finger 9 and the sliding plate 71 is increased, the linkage rod 961 pulls the limiting rod 96 to rotate, and the limiting rod 96 drives the needle tube 962 to rotate upwards. Then the pneumatic finger 9 drives the two clamping jaws to clamp the condom head, the driving rod of the electric cylinder 75 starts to retract to drive the pneumatic finger 9 to move back, so that a part of the condom head is pulled from the metal mold 21, meanwhile, as the distance between the pneumatic finger 9 and the sliding plate 71 is reduced, the linkage rod 961 pushes the limit rod 96 to rotate, so that the limit rod 96 drives the needle tube 962 to be inserted into the condom downwards, high-pressure air flow in the air source is input into the condom to blow off the inner wall of the condom from the metal mold 21, the resistance between the two is reduced, the limit spring 93 is restored to a natural state along with the retraction of the driving rod of the electric cylinder 75, the sliding plate 71 moves back synchronously under the pulling of the driving rod of the electric cylinder 75, the condom is separated from the metal mold 21 under the clamping of the pneumatic finger 9, and finally the two clamping jaws of the pneumatic finger 9 are separated, and the condom falls under the action of gravity. During the process of releasing the condom from the metal mould 21, the belts 74 at the two sides keep a rolling state and can also play a role of boosting, and the two supplement each other.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
