Then, the rotary cylinder is started to drive the rubber band to rotate 180° and then move down again to be sleeved outside the nail roll. At this time, the pneumatic push rod is contracted to disengage from the rubber band for the socketing of the nail roll. At the same time, on the other side, the rubber band is taken synchronously for the waiting socketing preparation, facilitating the synchronous progress of taking at one end and socketing at the other end, thus improving the processing speed, reducing the waiting time, and improving the processing efficiency. 3. When the rubber band on the outer side of the feeding screw on one side is used up, the first cylinder is started to drive the first support plate to move to the other feeding screw through the push plate, without waiting for the feeding of the feeding screw, thus further accelerating the processing efficiency.
