[0007] The pusher head driving device is connected to the pusher head and is used for driving the pusher head downward to push the material roll core of the material roll supported by the support plate downward onto the battery foil.

[0008] Furthermore, the support plate is slidably arranged on a frame so as to slide in and out directly below the pusher head.

[0009] Furthermore, a locking pin is screwed and installed through the support plate, and a pin hole for inserting the end of the locking pin is provided on the frame. The locking pin slides with the support plate so that its end is directly opposite to or deviates from the pin hole.

[0010] Furthermore, a cushion block is fixed on the frame, and when the support plate slides to just below the push head, the cushion block is located between the frame and the support plate.
