The insulating paper has good insulation performance and can greatly improve the working performance of the motor. Therefore, there is a paper inserting machine. The paper inserting machine is a device for inserting insulating paper into the slots of the armature rotor. The armature rotor is manually placed on a positioning fixture, and the machine feeds paper with a cylinder or a belt, forms it with a mold, then inserts the insulating paper into the slots of the armature rotor with a cylinder, and finally the inserted armature rotor is manually removed. In the existing design, a conveying device for a paper inserting machine is disclosed in a Chinese patent with the authorization announcement number CN212231306U, which includes a paper feeding tray, a forming device and a conveying device, and a frame for installing the paper feeding tray, the forming device and the conveying device. The paper feeding tray is used for winding insulating paper.

[0003] The paper feeding tray disclosed above is a conventional paper winding tray at present. It has the following problems in the using process: the insulating paper is wound in the winding tray. In order to perform side limit on the insulating paper during winding, the two sides of the winding tray are in contact with the insulating paper. The two sides of the existing winding tray are fixed. With such a structural setting, during the process of pulling the insulating paper, the two sides of the winding tray are likely to cause certain resistance to the insulating paper, resulting in poor pulling of the insulating paper. Seriously, it will also cause wear and damage to both sides of the insulating paper and lead to scrapping. Therefore, it needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a paper feeding rack with a pressure prevention and resistance reduction mechanism, which solves the problem that the two sides of the existing winding tray are likely to cause certain resistance to the insulating paper, resulting in poor pulling of the insulating paper. Seriously, it will also cause wear and damage to both sides of the insulating paper and lead to scrapping.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figures 1-9 As shown, a paper feeding rack with an anti-pressure and resistance-reducing mechanism disclosed in this embodiment includes a paper feeding rack shaft 1. A left insulating paper retaining disc 2 and a right insulating paper retaining disc 3 are inserted on the paper feeding rack shaft 1 at intervals. A support block 4 sleeved outside the paper feeding rack shaft 1 is arranged between the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3. The support block 4 is used to support the insulating paper. A paper disc baffle cover 5 is arranged on each of the opposite sides of the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3. The paper disc baffle cover 5 is sleeved outside the paper feeding rack shaft 1. A set screw one 6 with its head abutted against the side of the paper feeding rack shaft 1 is threadedly connected to the right paper disc baffle cover 5. A circular groove 7 is arranged on the paper feeding rack shaft 1. A ball head set screw 8 is threadedly connected to the left paper disc baffle cover 5. The ball head on the ball head set screw 8 is placed in the circular groove 7.

[0031] Preferably, a limiting ring 9 is arranged on each of the opposite sides of the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3. A limiting groove 10 sleeved outside the limiting ring 9 is arranged on the side of the paper disc baffle cover 5.

[0032] Preferably, more than one sector-shaped hollowed-out part 11 is circumferentially distributed on the paper disc baffle cover 5. A rib 1101 is arranged on the side of the sector-shaped hollowed-out part 11 away from the insulating paper. By arranging a plurality of sector-shaped hollowed-out parts 11 on the paper disc baffle cover 5, while reducing the weight of the product, the contact area with the insulating paper wound between the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3 becomes smaller, and ultimately the friction force can be further reduced.

[0033] Preferably, more than one anti-slip rib 12 is annularly arranged outside the paper disc baffle cover 5. In this embodiment, by arranging the anti-slip rib 12, it is convenient to grasp the paper disc baffle cover 5 by hand later and can play an anti-slip role.

[0034] As Figure 9The internal structure schematic diagram of the ball head set screw 8 is shown. It includes a screw body 801 with external threads. A cavity is provided inside the screw body 801, and a spring 802 is arranged in the cavity. The other end of the spring 802 is connected with a ball head 803. The ball head 803 partially protrudes from the screw body 801. This structure realizes that when the left paper tray baffle cover 5 is inserted in place on the paper feeding rack shaft 1, at this time, the ball head 803 of the ball head set screw 8 just gets stuck in the annular groove 7, so as to realize the axial limit of the left paper tray baffle cover 5, which is convenient for installation and later disassembly of the left paper tray baffle cover 5. At the same time, when insulating paper is wound between the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3, since the left insulating paper retaining disc 2 is axially limited but not radially restricted, when the insulating paper is pulled by the paper inserting machine, the left side of the insulating paper is not restricted, avoiding the insulating paper being pressed by the left insulating paper retaining disc 2 and the right insulating paper retaining disc 3 on both sides, further reducing the resistance to the insulating paper and the problem of poor pulling of the insulating paper. Finally, it also avoids the problem of side wear of the insulating paper due to resistance during pulling.

[0035] Embodiment 2

[0036] Please refer to Figure 10 、 Figure 11As shown in the figure, a paper feeding rack with an anti-pressure and resistance-reducing mechanism disclosed in this embodiment. Preferably, a positioning sleeve 13 is sleeved outside the paper feeding rack shaft 1. The annular groove 7 is arranged on the positioning sleeve 13. A second set screw 14 is threadedly connected to the side of the positioning sleeve 13. The head of the second set screw 14 abuts against the paper feeding rack shaft 1. The left paper disk baffle cover 5 is sleeved outside the positioning sleeve 13. More than one support block 4 is arranged between the left insulating paper stop disk 2 and the right insulating paper stop disk 3. Two metal sheets 15 are arranged on the left side of the support block 4. A magnet 16 that magnetically attracts the metal sheet 15 is arranged on the right side of the support block 4. In this embodiment, there can be multiple support blocks 4. Only two support blocks are shown in this embodiment. In actual situations, there can be three or more. Since each support block 4 has a metal sheet 15 on the left side and a magnet 16 on the right side, during assembly, multiple support blocks 4 are overlapped in sequence to form a certain thickness, and then they are sleeved outside the paper feeding rack shaft 1. At this time, the left insulating paper stop disk 2 is sleeved on the left side of the paper feeding rack shaft 1, and the positioning sleeve 13 is sleeved on the left side of the left insulating paper stop disk 2. Then, the second set screw 14 is threadedly connected to the threaded hole of the positioning sleeve 13 until the head of the second set screw 14 abuts against the paper feeding rack shaft 1. Finally, the positioning sleeve 13 is locked on the paper feeding rack shaft 1. Then, the left paper disk baffle cover 5 is sleeved outside the positioning sleeve 13, and the ball head set screw 8 is used to lock the left paper disk baffle cover 5, ensuring that the head of the ball head set screw 8 is stuck in the annular groove 7. Therefore, through the above structural settings, the distance between the left insulating paper stop disk 2 and the right insulating paper stop disk 3 can be changed, enabling the winding operation of insulating papers with different widths, and further improving the versatility of this device.

[0037] Embodiment 3

[0038] Please refer to Figures 12-13 As shown in the figure, a paper feeding rack with an anti-pressure and resistance-reducing mechanism disclosed in this embodiment. Preferably, a limiting notch 17 is arranged on the support block 4, and a winding rod 18 for positioning the insulating paper is arranged in the limiting notch 17. In this embodiment, by arranging a limiting notch 17 on the support block 4 and then arranging a winding rod 18 in the limiting notch 17, in the initial state, one end of the insulating paper is passed through the limiting notch 17 and wound around the winding rod 18 to achieve the positioning of the head of the insulating paper. Then, the insulating paper is wound outside the support block 4. Finally, the paper feeding rack wound with the insulating paper is installed on the corresponding paper inserting machine.

[0039] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made all fall within the protection scope of the present invention.
