rotating rod 21 to rotate, the second rotating rod 21 rotates to drive the first sliding rod 22 to rotate, the first sliding rod 22 rotates to drive the second disconnecting device 101 to rotate back to the original position, meanwhile, the second electromagnet 85 is powered off, the first sliding rod 22 moves under the resilience acting force of the second spring 23, the first sliding rod 22 moves to drive the second disconnecting device 101 to move, the second disconnecting device 101 moves to separate from the material, and then the third electromagnet 31 is electrified to attract the third iron block 34 to move, the third iron block 34 moves to drive the second sliding rod 35 to move, the second sliding rod 35 moves to drive the first wheel shaft 37 to move, the first wheel shaft 37 moves to drive the first pressing wheel 36 to move, then the material moves under the drive of the feeding motor, when the welding part passes through the cutting cavity 40, the cutting knife 39 takes out the welding redundant part, meanwhile, the fourth electromagnet 45 is electrified to attract the fourth iron block 44 to move, the fourth iron block 44 moves to drive the sliding block 43 to move, the sliding block 43 moves to drive the moving block 88 to move, then the second rotating motor 70 is started to control the second rotating shaft 28 to rotate by one hundred eighty degrees, the second rotating shaft 28 rotates to drive the rotating plate 27 to rotate, the rotating plate 27 rotates to drive the first fixed shaft 29 and the second fixed shaft 26 to rotate, the first fixed shaft 29 rotates to drive the first material disc 30 to rotate, the second fixed shaft 26 rotates to drive the second material disc 25 to rotate, then the second electromagnet 85 is electrified to attract the second iron block, the second iron block 86 moves to drive the first sliding rod 22 to move, and the first sliding rod 22 moves to drive the second disconnecting device 101 to move and return to the original position.

Repeating the above steps to replace with new material.
