The web-to-web co-lamination machine of claim 31 wherein: the belt material heating device also comprises a tension mechanism for keeping the belt material at a set tension in the heating device; the tension mechanism is arranged at the rear side of the heating device, and the hot rolling composite device is arranged at the front side of the heating device.

33. A sheet-strip synergistic lamination method, characterized in that: the reciprocating folding mechanism drives the strip to fold back and forth on the lamination table, and the sheet conveying mechanism conveys the sheet to a position close to the lamination table in the process that the reciprocating folding mechanism drives the strip to move from one end of the reciprocating folding to the other end of the reciprocating folding; the reciprocating folding mechanism drives the strip material to reach the other end from one end of the reciprocating folding, the strip material is positioned by the folding positioning mechanism, one-time folding of the strip material is completed, and then the strip material positioned beside the lamination table is stacked above the strip material folded on the lamination table by the strip material transferring mechanism; after the stacking of the sheets is completed, the reciprocating folding mechanism is utilized to drive the belt material to move towards the other end of the reciprocating folding, and the reciprocating circulation is performed until the stacking is completed.

34. The sheet-strip co-lamination method of claim 33, wherein: the reciprocating folding mechanism comprises a folding guide mechanism and a folding driving mechanism; the folding guide mechanism comprises a swing arm, two ends of the swing arm are respectively a moving end and a swinging end, the moving end of the swing arm can rotate relative to a rotating shaft, the swinging end is provided with a first guide roller group for guiding a belt material, the folding drive mechanism comprises a drive assembly for driving the moving end of the swing arm to move along a preset track and a swinging assembly for driving or guiding the swing arm to rotate around the rotating shaft, and the preset track comprises at least one vertical track vertical to the lamination table; the first guide roller group moves back and forth relative to the lamination table under the combined action of the linear motion of the swing arm moving end along the direction vertical to the lamination table and the rotary motion of the swing arm around the rotating shaft so as to fold the belt material back and forth on the lamination table;

the method comprises the following steps:

Stacking the sheets on a stacking table by using a sheet stacking mechanism;

35. The sheet-strip co-lamination method of claim 34, wherein: the sheet material transferring mechanism comprises a fixed seat positioned above the sheet material conveying mechanism and a movable seat positioned between the fixed seat and the sheet material conveying mechanism, and a first driving mechanism for driving the movable seat to move along the vertical direction is arranged on the fixed seat; the movable seat is provided with a horizontal sliding rail, the horizontal sliding rail is provided with a sliding seat in sliding fit with the horizontal sliding rail, the bottom surface of the sliding seat is provided with sucking discs in an array manner, and the movable seat is provided with a second driving mechanism for driving the sliding seat to reciprocate between the lamination table and the sheet conveying mechanism along the horizontal sliding rail;
