When the anti-deviation connecting rod 62 moves, it passes through the mold base 57 and is inserted into the forming groove 56.1. The anti-deviation connecting rod 62 cooperates with the punch 55 to clamp the slot paper 4 to prevent the slot paper 4 from deviating in other directions and affecting the push rod 40 to push the slot paper 4 into the insulating groove 42.1 of the stator 42.

[0043] The base plate 58 is provided with a stator turntable device moving assembly, which includes a second servo motor 63, a screw drive assembly 64 and a sliding connecting plate 65. The second servo motor 63 drives the screw drive assembly 64, which includes a screw, a nut and a nut seat. The sliding connecting plate 65 connects the nut seat and the turntable mounting seat 59. The second servo motor 63 is fixed to the base plate 58. The second servo motor 63 drives the turntable mounting seat 59 to move on the base plate 58 in turn through the screw drive assembly 64 and the sliding connecting plate 65. To drive the entire stator turntable device H to move on the base plate 58; the stator turntable device moving assembly is used to adjust the position of the stator turntable device H on the base plate 58 to accommodate stators 42 of different diameters. Because different stators 42 have different diameters, and the positions of the paper feeding mechanism and the slot paper forming mechanism are fixed, it is necessary to adjust the position of the stator 42 on the base plate 58 for stators 42 of different diameters so that the insulating slot 42.1 of the stator 42 is always located directly above the die 56, so that the slot paper 4 can be accurately installed in the insulating slot 42.1.

[0044] The slot paper machine also includes a slot paper placement rack assembly I, a pre-pressing and heating device J and an indentation and edge pressing device K. The slot paper placement rack assembly I, the pre-pressing and heating device J, the indentation and edge pressing device K, the corner cutting device C, the flanging device B, the paper feeding and pressing device A and the cutting and pressing device D are connected in sequence. When the slot paper machine is working, the operator manually rolls the slot paper 4 into the paper feeding and pressing device A through the slot paper placement rack assembly I, the pre-pressing and heating device J, the indentation and edge pressing device K, the corner cutting device C and the flanging device B, and then the paper feeding and pressing device A automatically conveys the slot paper 4 upward; the pre-pressing and heating device J can preheat the slot paper 4 so that the slot paper 4 can be better attached to the paper feeding slot, which is beneficial to the conveyance of the slot paper 4 and improves the quality of the formed slot paper 4.

[0045] The vertical slotted paper machine is a double-station slotted paper machine, which can simultaneously install slotted paper 4 on two stators 42.
