An electromagnet opening switch 26 is arranged on the lower demoulding rod 221 close to the output channel of the round cover. When the round cover 6 is abutted with the inner end of the round cover output channel, the round cover is still supported on the lower demoulding rod provided with the electromagnet opening switch, and the center of the round cover is aligned with the upper end of the round cover sliding hole. The electromagnet opening switch is a normally open push switch. The electromagnet starting switch and the electromagnet are connected in series on the power supply.

The round cover stacking and barreling mechanism comprises a closing section 71 which is butted at the lower end of a round cover sliding hole and enables the round cover to fall out in a vertical mode and a horizontal cylindrical section 72 which is positioned below the closing section. One end of the horizontal cylindrical section is provided with a downwardly sloping dome outlet 73. The inner diameter of the round cover outlet is equal to the diameter of the round cover 6.

Then the punch lifting cylinder drives the punch to ascend, the female die driving mechanism drives the female die to descend so as to open the die, the upper demoulding rod is driven by the upper demoulding rod driving spring to extend downwards out of the punch so as to separate the round cover from the punch, the female die driving mechanism contracts so as to enable the lower demoulding rod to extend out of the female die and prop against the round cover 6, at the moment, the electromagnet driving switch is pressed so as to enable the pressing head to contract and be closed, after the upper demoulding rod driving spring drives the upper demoulding rod driving spring to extend downwards, the electromagnet is communicated with a power supply, the electromagnet generates magnetic force to attract the round cover to enter the round cover output channel and is abutted with the inner end of the round cover output channel (at the moment, the electromagnet driving switch is still pressed by the round cover, namely, the electromagnet still has magnetic force, so that the round cover still cannot fall into the blanking slideway), then the female die driving, under the action of the weight, i.e. the top of the female die, the round cap falls into the discharging slideway and slides out of the discharging slideway to enter the closing section 71. Under the reversing limit action of the closing section, the round cover falls onto the inclined surface 721 on the horizontal cylindrical section in a vertical mode, and under the inclination action of the inclined surface, the round cover is inclined towards the material pushing mechanism 74 and leans against the push block 741. The translation cylinder 742 drives the push block to translate towards the round cover outlet, stops extending when translating to the joint of the round cover outlet and the horizontal cylindrical section, is responsible for the extension of the air hole to enable the round cover to swing and turn over to be in the round cover outlet, and then slides into the barrel 9 for containing the round cover from the round cover outlet.
