[0002] At present, the interlayer insulation paper insertion machine is a mechanical equipment that inserts insulation paper of a certain shape into the interlayer of the stator core coil.

After the paper folding is completed, the indentation plate 442 and the indentation retreat plate 445 respectively retreat out of the gap cavity 4451, and the folded insulating paper is pushed up into the paper folding forming mold 448 by the lifting and inserting paper mechanism 45, During the jacking process, the right origami guide slope 44821 and the left origami guide slope 44831 on the opposite side edges of the right origami block 4482 and the left origami block 4483 are used to guide and shape the two sides of the insulating paper during folding, and the forming effect of the origami forming groove 44811 is cooperated to complete the folding to obtain the formed insulating paper 8, and finally, under the jacking of the lifting rod 454, the formed insulating paper 8 is inserted into the coil slot to be inserted into the stator 5. For each pair inserted at the double station, the turntable on the surface of the paper insertion placement rack 7 rotates one scale to insert the next pair of formed insulating paper 8. After all the insertion processes are completed, the transfer mechanism 2 is used to grab and place it on the feeding mechanism 1 to unload from the other end, and the reciprocating cycle is completed to complete the automatic paper insertion of the motor stator.
