5. The continuous blanking and scrap recycling system for battery insulating sheets according to claim 1, characterized in that: first roll up the part including setting up the first roll up axle of side waste recovery station top, auxiliary component is located the below of first roll up axle is pressed and is established on the insulating piece, works as the insulating piece certainly when side waste recovery station feed end moves backward, the side waste material breaks away from the insulating piece, and the process upwards roll up behind the auxiliary component extremely on the first roll up axle.

6. The continuous blanking and scrap recycling system for battery insulating sheets according to claim 5, characterized in that: the first winding component further comprises a tension roller, the tension roller is located above the auxiliary component, during winding, the side waste materials pass through the auxiliary component and wind around the tension roller from the front upper side to be wound onto the first winding shaft, and an included angle between the side waste materials and the insulating sheet between the tension roller and the side waste material recycling station is 40-80 degrees.

7. The continuous blanking and scrap recovery system for battery insulating sheets according to claim 5 or 6, characterized in that: the auxiliary component includes from both ends fixed connection be in dead lever on the side waste recycling station, connect on the dead lever and with the clamp plate that the insulating piece paralleled, wherein the clamp plate will the insulating piece restriction is in on the side waste recycling station, the side waste material breaks away from behind the insulating piece from keep away from on the clamp plate dead lever one side upwards roll-up to on the first roll-up shaft.

8. The continuous blanking and scrap recycling system for battery insulating sheets according to claim 7, characterized in that: the clamp plate is followed insulating piece width direction's both ends are appeared and are located the insulating piece both sides the side waste material, the side waste material breaks away from during the insulating piece, the clamp plate is from keeping away from dead lever one side is contradicted on the side waste material.

9. The continuous blanking and scrap recycling system for battery insulating sheets according to claim 1, characterized in that: the second winding component comprises an adhesive tape roll, a second winding shaft and a laminating roller, wherein the adhesive tape roll is arranged above the middle waste recovery station, the adhesive tape roll is unwound from the adhesive tape roll and extends downwards to the surface of the insulating sheet, the adhesive tape roll extends upwards and winds the insulating sheet to the second winding shaft, the laminating roller presses the adhesive tape to the surface of the insulating sheet, and the middle waste is adhered to the adhesive tape.

10. The continuous blanking and scrap recycling system for battery insulating sheets according to claim 9, characterized in that: the laminating roller includes laminating roller and lower laminating roller, go up the laminating roller with the laminating roller sets up respectively down both sides about the insulating piece, just go up the laminating roller with the laminating roller rotates the setting relatively down, works as when the insulating piece removes, go up the laminating roller with the laminating roller will down the middle part waste material with the sticky tape is laminated mutually.
