[0021] The paper roll is unwound by the paper unwinding mechanism 8, so that the insulating paper enters the pre-folding mechanism 9, and the position where the insulating paper needs to be folded is indented at the pre-folding mechanism 9. The indented insulating paper enters the forming mechanism 5, and is folded and formed by the forming mechanism 5. Then, the insulating paper formed in the forming mechanism 5 is cut by the paper cutting mechanism 6, and then the formed insulating paper is pushed upward by the paper inserting mechanism 7 and inserted into the stator in the positioning and rotating mechanism 3.

[0022] Specifically, the positioning and rotating mechanism 3 includes a fixed plate 31, a swivel seat 32, a guide plate 33 and a positioning plate 34.

[0023] By setting the positioning plate 34, the stator supported on the guide plate 33 can be supported and positioned, so that the multiple stator slots on the stator can be more easily aligned with the multiple clearance holes respectively. When inserting paper into the stator on the guide plate 33, one of the positions on one side of the guide plate 33 is used as the paper insertion position. By rotating the swivel seat 32, the stator slots on the stator are driven to move to the paper insertion position in sequence for paper insertion until all stator slots are inserted with paper.
