Because the pop can covers 61 in the can cover box 35 are reduced by one, the pressure of the lifting spring 34 is reduced, the second pop can cover 61 on the upper surface is slightly lower than the bottom surface of the sliding groove 41, the collision of the special-shaped push rod 37 to the pop can covers 61 in the can cover box 35 is eliminated, and the conveying stability is improved. The piston rod of the second cylinder 36 extends out to drive the special-shaped push rod 37 to move rightwards, and then the zip-top can cover 61 is pushed to move along the sliding groove 41 through the arc-shaped plate 371 until the zip-top can cover moves right above the zip-top can body 60. The piston rod of the second cylinder 36 is retracted so that the contour push rod 37 returns to the initial position. The piston rod of the third cylinder 52 extends to the highest working position, the sliding ejector rod 55 jacks up the pop can body 60 and the pop can cover 61 right above, so that the pop can cover 61 contacts the can cover counter bore 501, and the pressing spring 54 generates obvious compression deformation, thereby sealing the pop can body 60 under the counter-acting force of the pressing spring 54. After the sealing is finished, the pop can be taken away by other mechanical arms, and the piston rod of the third cylinder 52 retracts, so that the sliding ejector rod 55 returns to the lowest working position. The stepping motor 24 rotates to drive the rotating shaft 23 to rotate, so that the next pop can body 60 to be sealed moves to the position right above the sliding ejector rod 55, and a sealing process is completed. The above actions are repeated continuously, and the automatic sealing operation of the pop can be implemented in a running water type full-automatic mode.
