[0002] The stator consists of three parts: the stator core, the stator winding and the frame. The stator winding is wound on the stator core. In order to ensure that there is no interference between the stator windings, insulating paper strips need to be inserted into the stator slots of the stator core before winding the stator winding.

[0003] The paper inserter is a device that automatically inserts the insulating paper into the rotor slot of the rotor. The paper inserters in the prior art all fold the insulating paper into shape through a plurality of gradually changing folding forming blocks. However, since the forming has a certain margin and under the action of the traction force at both ends of the insulating paper, the insulating paper is prone to positional displacement, which causes the folding line to deviate from the center line of the insulating paper, resulting in a poor folding forming effect of the insulating paper, resulting in the insulating paper insert strip being unable to be smoothly inserted into the stator slot, affecting the paper inserting efficiency. Utility Model Content

The pre-bending block 31 is used to bend the insulating paper, the crease forming block 32 is used to form a crease in the middle of the insulating paper along its length direction, and the folding forming block 34 is used to fold the insulating paper in half. Through the design of the crease forming block, a crease is formed on the insulating paper, which is convenient for locating the folding center of the insulating paper, so that the insulating paper has a good folding effect, and avoids errors on both sides after folding, which may cause the paper to be unable to be inserted into the rotor slot of the rotor.

[0041] like Figure 2As shown, the pre-bending block 31 has a pre-bending cavity 311 for insulating paper to pass through, and the pre-bending cavity 311 includes a first left half cavity 3111 and a first right half cavity 3112 which are interconnected. The first right half cavity 3112 gradually deflects toward the first left half cavity 3111 from its input end to the output end, and the output end of the first left half cavity 3111 is in a horizontal state.
