[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 5 As shown, a paper inserting machine of the present invention includes a main frame 9 and a paper feeding mechanism. The main frame 9 is provided with a support plate 1 and a transverse plate 5. The paper feeding mechanism is provided between the support plate 1 and the transverse plate 5.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, the paper feeding mechanism includes at least one first clamping mechanism for clamping and conveying insulating paper and a first driving member 10 for driving the first clamping mechanism to convey the insulating paper; the first clamping mechanism includes two groups of guide rods 6, a fixed frame 7 and a first clamp 3, a fixed frame 7 is provided between the two groups of guide rods 6, the fixed frame 7 is slidably connected to the guide rods 6, and the first clamp 3 is provided on the fixed frame 7; the output end of the first driving member 10 is connected to the fixed frame 7.

[0029] It should be noted that the first driving member 10 is a cylinder, which drives the fixing member to move, thereby driving the first clamp 3 to move; when the first clamp 3 clamps and fixes the insulating paper, the insulating paper is transported, and then when the first clamp 3 releases the insulating paper, it drives the first clamp 3 to reset.

[0030] Specifically, in this embodiment, the paper feeding mechanism also includes at least one second clamping mechanism 4 for preventing the insulating paper from shrinking. When the first clamping mechanism loosens the insulating paper, the second clamping mechanism 4 immediately clamps and fixes the loosened insulating paper to prevent the insulation from shrinking. The structure of the second clamping mechanism 4 is the same as that of the first clamping mechanism. The second clamping mechanism 4 is located below the first clamping mechanism. The first clamping mechanism can move up and down relative to the main bracket 9, and the second clamping mechanism 4 is fixed on the main bracket 9.

[0031] like Figure 6 and Figure 7 As shown, the first clamp 3 includes a second driving member 12, a paper rod 14 and a clamping structure. The second driving member 12 cooperates with the clamping structure. The second driving member 12 is connected to the fixed frame 7. The paper rod 14 is fixedly connected to the inner side of the fixed frame 7 away from the second driving member 12. The clamping mechanism cooperates with the paper rod 14; a conveying channel 15 for conveying stator insulation paper is formed between the paper rod 14 and the fixed frame 7. The output shaft of the second driving member 12 is connected to a pressure block 13. The end of the pressure block 13 is formed with a smooth surface, which has a good actuation effect.

[0032] Furthermore, in this embodiment, Figure 6 and Figure 7 As shown, the clamping structure includes a first clamping arm 17 and a second clamping arm 18, the first clamping arm 17 and the second clamping arm 18 are hinged by a support shaft, the support shaft is connected to the fixed frame 7, and a return spring 16 is provided between the first clamping arm 17 and the second clamping arm 18; the first clamping arm 17 and the second clamping arm 18 can rotate relative to each other under the action of the support shaft; the other end of the first clamping arm 17 and the second clamping arm 18 are provided with a rolling member 11, the rolling member 11 and the first clamping arm 17 and the second clamping arm 18 are all rotatably connected, and the rolling member 11 and the pressure block 13 are in the same horizontal plane, so that the contact between the rolling member 11 and the pressure block 13 is more stable, avoiding displacement when the pressure block 13 applies pressure to the rolling member 11; one end of the first clamping arm 17 and the second clamping arm 18 are respectively provided with a clamping block, and the clamping block is rotatably connected to the first clamping arm 17 and the second clamping arm 18; the first clamping arm 17 and the second clamping arm 18 clamp and fix the insulating paper through the clamping block.

[0033] It should be noted that the second driving member 12 drives the pressure block 13 to move linearly. Since the end of the pressure block 13 is formed with a smooth surface, friction can be reduced. At the same time, the rolling member 11 converts the sliding force into a rotational force, causing the first clamping arm 17 and the second clamping arm 18 to open under the pressure of the pressure block 13. At the same time, the return spring 16 is stretched, driving the clamping block away from the insulating paper, so that the insulating paper can flexibly pass through the conveying channel 15 formed between the paper rod 14 and the fixed frame 7. When the insulation needs to be fixed, the second driving member 12 drives the pressure block 13 to retract, and the return spring 16 resets, driving the first clamping arm 17 and the second clamping arm 18 to clamp. The first clamping arm 17 and the second clamping arm 18 drive the clamping block to clamp and fix the insulating paper under the support of the paper rod 14, thereby preventing the insulating paper from deforming under the support of the paper rod 14.

[0034] Furthermore, different first clamps 3 and second clamping mechanisms 4 are replaced according to different shapes of insulating paper, wherein the clamping members can clamp and fix insulating paper of different shapes.

[0035] like Figure 2 and Figure 3 As shown, the fixing frame 7 is provided with a shaft sleeve, and the fixing frame 7 is connected to the guide rod 6 through the shaft sleeve. The fixing frame 7 can slide up and down relative to the two guide rods 6; the fixing frame 7 is slidably connected to the guide rod 6 through the shaft sleeve, and the movable direction of the fixing frame 7 is limited by the guide rod 6.

[0036] like Figure 4 As shown, a guide structure 8 for conveying insulating paper is provided above the fixing frame 7. The guide structure 8 includes a guide bar 801 and a guide portion 803. A paper guide channel is provided inside the guide portion 803. The guide bar 801 for guiding the insulating paper is provided on the guide portion 803; multiple groups of guide needles 802 are provided on the outer side of the guide bar 801; an insulating paper shaping channel is formed between the multiple groups of guide needles 802 and the guide bar 801; the formed insulating paper is further shaped by the guide needles 802 and the guide bar 801, so that the insulating paper is easily inserted into the stator core in a one-step operation.

[0037] It should be noted that the guide needle 802 and the guide bar 801 are also used to maintain the upward shape of the insulation paper, drive the insulation to be inserted into the paper outlet 2 to enter the stator core, and avoid curling and other conditions during the insulation insertion process; making the insulation insertion process smoother and more efficient.

[0038] Furthermore, in this embodiment, a mounting portion 804 is provided on the guide portion 803; the guide structure 8 is fixed to the fixing frame 7 through the mounting portion 804, and the guide structure 8 can also be adjusted through the mounting portion 804; it should be noted that the mounting portion 804 is provided with a strip groove and is installed on the fixing frame 7 through bolts. By loosening the bolts and adjusting the guide portion 803, the guide portion 803 is made to correspond to the position of the paper outlet 2 on the main bracket 9, which is more convenient for inserting the multi-functional insulation into the paper outlet 2.

[0039] like Figure 1 and Figure 5 As shown, according to the second aspect of the present invention, a paper inserting machine is provided, including a main body bracket 9 and a paper feeding mechanism, wherein a support plate 1 and a transverse plate 5 are provided on the main body bracket 9, and the paper feeding mechanism is provided between the support plate 1 and the transverse plate 5.

[0040] During operation, the formed insulating paper is passed through the first clamp 3, the second clamping mechanism 4 and the paper outlet 2 in sequence. The first clamp 3 clamps the insulating paper, and the first driving member 10 pushes the fixing frame 7 to slide along the direction of the guide rod 6, thereby driving the insulating paper upward through the first clamp 3, shrinking and shaping the insulating paper through the guide structure 8, and inserting the insulating paper into the paper outlet 2 through the guide structure 8. The second clamping mechanism 4 clamps and fixes the insulating paper at the moment the first clamp 3 releases the clamp, and then the first clamping mechanism returns to its position to continue the insulation paper transportation work, and the cycle is repeated.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention. Such improvements and modifications should also be considered within the scope of protection of the present invention.
