[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] As Figures 1 to 15 shown, a paper inserting device for a slender water pump motor includes a paper feeding device 1, a paper pressing device, a hemming device 2, a paper cutting and forming device 4, a paper pushing device 7 and an indexing device 8. The paper feeding device 1 is used for quantitatively feeding paper; the paper pressing device is located at the feeding end of the paper feeding device 1 and is used for keeping the paper in a flat state; the hemming device 2 is installed on both sides of the paper pressing device and is used for hemming both sides of the paper; the paper cutting and forming device 4 is located at the discharging end of the paper feeding device 1 and is used for cutting the paper and pressing it into a bottom paper of a groove; the paper pushing device 7 is located on one side of the paper cutting and forming device 4; the indexing device 8 is arranged opposite to the paper cutting and forming device 4 and is used for fixing the stator and driving the stator to rotate, and the paper pushing device 7 is used for inserting the bottom paper of the groove into the stator slots of the stator.

[0033] The paper feeding device 1 feeds the paper from the reel into the paper cutting and forming device 4 to cut and press it into a U-shaped bottom paper of a groove. The paper feeding device 1 also makes the paper pass through the paper pressing device and the hemming device 2 to turn both sides of the paper, realizing the folding of both sides of the paper to obtain a hem, and meeting the width requirement of the hem. Then, the formed bottom paper of the groove is inserted into the stator slots of the stator through the paper pushing device 7. The indexing device 8 rotates the stator so that the stator slots are arranged opposite to the lower forming groove 471 of the paper cutting and forming device 4, thereby facilitating the insertion of the bottom paper of the groove into the stator slots.

[0034] The paper pressing device can prevent the problem of the paper bending inward under force during hemming, keep the paper in a flat state, and thus ensure that the width of the hem is consistent. The newly designed hemming device 2 can well fold both ends of the paper to obtain a hem with a large width.

[0035] Specifically, both the paper feeding device 1 and the paper cutting and forming device 4 are installed on a substrate 80, and the substrate 80 is installed on a frame (the frame is not shown in the figure).

[0036] The paper feeding device 1 includes a paper feeding base 15, a driving roller 13, a driven roller 12, a pressing device, a paper feeding gear set, and a paper feeding motor 17. The paper feeding base 15 is fixed on the substrate 80 and is located on one side of the substrate 80. Two pressing grooves 151 are symmetrically provided at the top of the paper feeding base 15, and the pressing grooves 151 are U-shaped open grooves. Both ends of the driving roller 13 are rotatably mounted on the paper feeding base 15 through bearings. A driven shaft 121 is rotatably installed inside the driven roller 12 through a bearing. Both ends of the driven shaft 121 are movably inserted into the pressing grooves 151, and through holes are provided at both ends of the driven shaft 121. The driven roller 12 is also located directly above the driving roller 13. The paper feeding gear set includes a driving paper feeding gear 19 and a driven paper feeding gear 18, and the two gears have the same specifications. The driving paper feeding gear 19 is fixed at one end of the driving roller 13, and the driven paper feeding gear 18 is fixed at one end of the driven roller 12 and meshes with the driving paper feeding gear 19. The paper feeding motor 17 is installed on the substrate 80 and is connected to the driving roller 13 to drive the driving roller 13 to rotate. The pressing device includes a pressing screw 16 and a pressing spring 14. The pressing screw 16 is movably inserted into the through hole of the driven shaft 121 and is screwed to the bottom of the pressing groove 151 through a thread. The pressing spring 14 is movably inserted onto the pressing screw 16, and both ends of the pressing spring 14 respectively abut against the driven shaft 121 and the nut of the pressing screw 16, and are used to press the driven roller 12 onto the driving roller 13, so as to press the paper between the driving roller 13 and the driven roller 12, enabling the paper to move following the rotation of the driving roller 13. Rotating the pressing screw 16 can adjust the magnitude of the pressing force.

[0037] The edge folding device 2 includes a folding cardboard 28, a guiding block 24, a folding seat 3, and a width adjusting device. The folding cardboard 28 is a flat plate, and the folding cardboard 28 is fixed on the paper feeding base 15 and is located at the feeding end. The width adjusting device includes an adjusting base 25, an adjusting shaft 22, a bidirectional threaded rod 23, and a handle 26. The adjusting bases 25 are fixed at both ends of the folding cardboard 28. Both ends of the bidirectional threaded rod 23 are rotatably mounted on the adjusting bases 25 through bearings. Both ends of the adjusting shaft 22 are respectively fixed on the two adjusting bases 25, and the adjusting shaft 22 is symmetrically located on both sides of the bidirectional threaded rod 23. The guiding blocks 24 are slidably inserted onto the two adjusting shafts 22. The two guiding blocks 24 are respectively provided with left-handed threads and right-handed threads and are respectively connected to the left-handed threaded rod and the right-handed threaded rod of the bidirectional threaded rod 23. The guiding blocks 24 are respectively located at both ends of the folding cardboard 28, and the bidirectional threaded rod 23 is used to adjust the distance between the two guiding blocks 24; the handle 26 is installed at one end of the bidirectional threaded rod 23 and is used to manually rotate the bidirectional threaded rod 23. A folding guiding groove 241 is provided at the bottom of the guiding block 24. The folding guiding groove 241 is arranged opposite to the folding cardboard 28, and the paper is inserted into the folding guiding groove 241 to limit the position of the paper and prevent the paper from moving left and right. There are two folding seats 3, which are respectively installed on the two guiding blocks 24 and are symmetrically arranged, and are used to flip both sides of the paper to obtain folded edges. The width adjusting device facilitates adjusting the positions of the two folding seats 3.

[0038] The paper pressing block 21 is installed on the adjusting shaft 22 and there are two of them. The paper pressing block 21 is equipped with set screws, and the set screws are arranged opposite to the adjusting shaft 22 for fixing the paper pressing block 21 on the guiding shaft, realizing the position fixation of the paper pressing block 21. The paper pressing block 21 prevents the paper from being bent under force during the edge folding process, keeping the paper in a flat state.

[0039] Among them, the paper folding seat 3 includes a paper folding base 35, a paper folding top seat 36 and a flipping seat 37. The paper folding base 35 is provided with a first paper folding block 351, and the first paper folding block 351 is provided with a first paper folding inclined surface 38; the paper folding top seat 36 is provided with a first flipping surface 32 and a second paper folding block 39. The first flipping surface 32 is located below the second paper folding block 39. The second paper folding block 39 is provided with a first paper folding inclined surface 38 opposite to the first flipping surface 32. The paper folding top seat 36 is fixed on the paper folding base 35. The second paper folding block 39 is located above the first paper folding block 351, and a paper feeding groove 31 is formed between the second paper folding block 39 and the first paper folding block 351; the flipping seat 37 is installed on the paper folding base 35 and is located below the second paper folding block 39. The flipping seat 37 is provided with a second flipping arc surface 33 and a folding arc surface 34. The second flipping arc surface 33 is arranged opposite to the first flipping surface 32. The folding arc surface 34 is arc-transitionally connected with the second flipping arc surface 33, and the folding arc surface 34 is arranged opposite to the second paper folding block 39. The end of the folding arc surface 34 and the second paper folding block 39 form a paper folding groove 30; the first flipping surface 32 is used for bending the end of the paper to 90° towards the back of the paper, the second flipping arc surface 33 is used for folding the 90° folded edge towards the back of the paper, and the folding arc surface 34, the second paper folding block 39 and the paper folding groove 30 completely fold the folded edge to the back of the paper. The first flipping surface 32, the second flipping arc surface 33 and the folding arc surface 34 are arranged in sequence for flipping the end of the paper by 180°, realizing a longer-width folded edge and solving the problem of the short folded edge width in the prior art. The first flipping surface 32 can also be an arc surface.

[0040] When folding the paper, the paper moves towards the paper feeding groove 31 in the paper folding guiding groove 241. Due to the limitation of the paper folding guiding groove 241, the paper will not move left and right or run up and down, and smoothly enters the paper feeding groove 31. Then, the end is flipped downward under the action of the first flipping surface 32, and the first paper folding inclined surface 38 and the second flipping arc surface 33 cooperate to prevent the paper from wrinkling when flipping. The first flipping surface 32 flips the end of the paper from the horizontal state to the state of 90° towards the back of the paper. The folded edge after being flipped by the first flipping surface 32 enters the second flipping arc surface 33, and the second flipping arc surface 33 continues to flip the folded edge towards the back of the paper, making the angle of the folded edge gradually change from 90° to 0°. When the folded edge enters the folding arc surface 34, since the end of the folding arc surface 34 becomes horizontal and forms a "one"-shaped paper folding groove 30 with the second paper folding block 39, the paper folding groove 30 makes the folded edge completely adhere to the back of the paper, completing the edge folding of the paper.

[0041] The paper cutting and forming device 4 includes a forming lower die 47, a forming top plate 48, a lower cutting knife 46, a forming upper die 53, an upper cutting knife 45, a lifting pressure plate 42, a lifting shaft 43, a lifting bottom plate 41 and a driving device. The forming lower die 47 is installed on the substrate 80 through a lower die base 49. The forming lower die 47 is located at the discharging end of the paper feeding device 1. A U-shaped lower forming groove 471 is provided at the top of the forming lower die 47, and a paper pushing guide groove 472 is provided on the side of the lower forming groove 471. The forming top plate 48 is fixed to the top of the forming lower die 47 and is located on one side of the lower forming groove 471. The forming top plate 48 and the forming lower die 47 form a first anti-folding groove 473. The lower cutting knife 46 is fixed to one side of the forming lower die 47. A second anti-folding groove 462 is provided on the lower cutting knife 46. The second anti-folding groove 462 is arranged opposite to the first anti-folding groove 473. The top of the lower cutting knife 46 is flush with the top of the forming top plate 48. A lower cutting edge 461 is provided on the other side of the lower cutting knife 46.

[0042] In order to ensure that the paper can accurately enter the forming die, a paper outlet plate 51 is also installed on one side of the upper cutting knife 45. A paper outlet groove 511 is provided at the center of the paper outlet plate 51, and the width of the paper outlet groove 511 is the same as that of the folded paper. The folded paper is accurately guided between the upper forming die 53 and the lower forming die 47, and the paper can follow the lifting and lowering of the upper cutting knife 45. After the paper is cut, it can be stably fed, and the forming and cutting of the paper can be continuously and stably carried out. This solves the problem that when the paper is fed from one side of the lower cutting knife 46, the paper is easily stuck at the lower cutting knife 46 and often requires manual intervention, and can realize continuous, stable and reliable paper feeding, improving the efficiency.

[0043] The paper pushing device 7 includes a paper pushing seat 55, a paper pushing block 57, a paper pushing rod 58, and a paper pushing driving device.

A top cover plate 56 is installed on the top of the paper pushing seat 55, and the top cover plate 56 closes the top of the paper pushing groove 551 to prevent the paper at the bottom of the groove from running out of the paper pushing groove 551.

[0044] The indexing device 8 includes an indexing plate 89, an indexing motor 81, a first indexing gear 82, and a third indexing gear 84. The indexing plate 89 is fixed on one side of the substrate 80 and is arranged opposite to the lower forming die 47. The indexing motor 81 is installed on the indexing plate 89, and the first indexing gear 82 is fixed on the indexing motor 81. The third indexing gear 84 is rotatably installed on the indexing plate 89 through a bearing seat. The third indexing gear 84 is connected to the first indexing gear 82 through a second indexing gear 83 to realize transmission. A number of indexing holes 841 are annularly arranged on the third indexing gear 84, and the indexing holes 841 correspond to the stator slots one by one. A fixed shaft 85 is installed on the third indexing gear 84, and the stator is inserted on the fixed shaft 85 to fix the stator and make the stator rotate with the third indexing gear 84.

[0045] During operation, the paper passes through the paper folding guide groove 241, the paper folding seat 3, the active roller 13, and the paper board 51 in sequence. The active roller 13 and the driven roller 12 move the paper toward the forming mold. The paper folding seat 3 folds the two ends of the paper. The folded paper enters between the forming upper mold 53 and the forming lower mold 47. Then the driving motor 61 drives the forming upper mold 53 and the upper cutter 45 to descend. The upper cutter 45 first contacts the lower cutter 46 to cut the paper. Then the forming upper mold 53 presses the cut paper into the forming lower mold 47 of the forming lower mold 47. The paper passes through the forming upper mold 53 and the lower forming groove 471 to form a U-shaped groove bottom paper. At this time, the two sides of the groove bottom paper are respectively located in the first anti-folding groove 473 and the second anti-folding groove 462. The first anti-folding groove 473 and the second anti-folding groove 462 restrict the groove bottom paper in the lower forming groove 471. Since the cutting and forming of the paper are completed almost at the same time, the paper is positioned during forming, and the forming of the groove bottom paper is stable and will not be skewed. After the bottom paper of the slot is formed, the paper pushing motor 71 is started, and the paper pushing motor 71 enables the paper pushing block 57 to insert the bottom paper of the slot into the stator slot through the linear guide 75 and the belt transmission mechanism, and the bottom paper of the slot enters the indexing hole 841 through the paper pushing seat 55, and enters the stator slot through the indexing hole 841. Since the first anti-folding groove 473 and the second anti-folding groove 462 cooperate with the lower forming groove 471, the bottom paper of the slot can be effectively prevented from bending, so that the bottom paper of the slot can be smoothly inserted into the stator slot, and the stability and reliability of the paper insertion are improved. The paper pushing seat 55 is used for transition, and the seamless connection between the forming lower mold 47 and the indexing hole 841 is realized, so that the bottom paper of the slot always keeps the state unchanged during the paper insertion process, and the problem of paper insertion failure caused by the rebound of the bottom paper of the slot is solved. The indexing device 8 rotates an angle every time the paper insertion of a stator slot is completed, and the paper insertion of the next stator slot is carried out until all stator slots are completed.
