Description

Technical Field

[0001] The invention relates to a vertical slotted paper machine, in particular to a double-station vertical slotted paper machine. Background Art

[0002] In the motor industry, stator slot paper is a crucial component of the motor's overall insulation structure. It not only insulates the coils but also provides mechanical support and secures them. More importantly, it provides stronger insulation protection, improves the motor's temperature resistance, and increases its stability and reliability during long-term operation. The quality of the stator slot paper determines the motor's service life.

[0003] During the stator slot paper forming process, it needs to be bent into a fixed shape and size, and the slot paper has flanges and notches on both sides. The slot paper is generally formed in one step through a forming mold. However, this one-step forming method requires high precision of the forming mold, and the quality of the formed slot paper is generally poor. There is a problem that the shape and size of the flanges and notches are significantly different from the actual shape and size requirements, which affects the protective effect of the slot paper on the motor.

[0004] In addition, when traditional slotted paper machines cut the slotted paper, the slotted paper will move in the direction opposite to the paper feeding direction, which also affects the quality of the formed slotted paper. In addition, the stator diameters of different motors are different. Since the position of the slotted paper forming mechanism is fixed, for stators of different diameters, when adding slotted paper, the position of the stator needs to be adjusted so that the insulating slot of the stator is always located above the forming die. Traditional slotted paper machines generally have an adjustment structure in the stator turntable device to adjust the position of stators of different diameters, but the adjustment structure is relatively complex, the cost is high, and the adjustment steps are cumbersome.

[0005] Therefore, further improvements are necessary. Summary of the Invention
