[0023] Insulating paper is the general term for electrical insulating paper, which is used as the insulating material for various electrical equipment such as cables and coils. In addition to having good insulation performance and mechanical strength, each type also has its own characteristics. Insulating paper products can usually be seen wherever electrical insulation is required.

[0024] During the transportation process, insulating paper may become loose, or during the winding process, due to insufficient winding, the paper sheets are not compact. Therefore, a rewinder is needed to rewind the loose insulating paper roll. The existing rewinder cannot adjust the tension during the rewinding process, resulting in the rewound paper roll becoming loose again.

[0025] See Figure 1 , this application provides an insulating paper rewinding mechanism, which includes a horizontal bracket 1, a first vertical bracket 2, and a second vertical bracket 3. A unwinding device 4 is installed on the horizontal bracket 1. The first vertical bracket 2 is connected to the horizontal bracket 1. A driving motor 5 and a winding device 6 are installed on the first vertical bracket 2. The winding device 6 is connected to the power output end of the driving motor 5. The second vertical bracket 3 is connected to the horizontal bracket 1. A transmission roller device 7 is installed on the second vertical bracket 3. The transmission roller device 7 includes a sliding seat 70, a first roller shaft 71, and a second roller shaft 72. The sliding seat 70 is slidably installed on the second vertical bracket 3. The sliding seat 70 can slide along the length direction of the second vertical bracket 3. The first roller shaft 71 and the second roller shaft 72 are both rotatably connected to the sliding seat 70. The outer surface of the first roller shaft 71 is in contact with the outer surface of the second roller shaft 72.

[0026] During use, the insulating paper reel is installed on the unwinding device 4, and then the insulating paper is pulled through the gap between the first roller shaft 71 and the second roller shaft 72 and wound around the winding device 6. By adjusting the sliding seat 70, the insulating paper is in a tensioned state, and then the driving motor 5 drives the winding device 6 to rotate to complete the rewinding of the insulating paper. This rewinding mechanism can adjust the tension of the insulating paper through the transmission roller device 7, so it can effectively prevent the paper roll from becoming loose during the rewinding process.

[0027] In order to ensure that the unwinding device 4 releases the insulating paper smoothly, in some embodiments, the unwinding device 4 is installed on the horizontal bracket 1 through a rotary damper 8. This ensures that the insulating paper remains tensioned between the transmission roller device 7 and the unwinding device 4.

[0028] Specifically, the horizontal bracket 1 is horizontally installed at the top of the first vertical bracket 2 and the second vertical bracket 3. The rotary damper 8 is installed on the horizontal bracket 1, and the unwinding device 4 is connected to the rotary damper 8.

[0029] The second vertical bracket 3 is provided with a vertical chute, and the sliding seat 70 is provided with a slider, which is assembled in the chute, so as to realize the sliding connection between the sliding seat 70 and the second vertical bracket 3. In addition, the sliding seat 70 is provided with a bolt hole, and a connecting bolt is arranged in the bolt hole. After the sliding seat 70 slides to the predetermined position, the bolt in the bolt hole is rotated so that the bolt abuts against the second vertical bracket 3 to position the sliding seat 70.

[0030] In some embodiments, the driving roller device 7 further includes a power component 73, which is installed on the sliding seat 70. The power output end of the power component 73 is connected to the first roller shaft 71, and the rotation speed of the first roller shaft 71 is less than that of the winding device 6. The power component 73 drives the first roller shaft 71, and the first roller shaft 71 drives the insulating paper threaded between the first roller shaft 71 and the second roller shaft 72 to move, which is convenient for pulling out the insulating paper on the unwinding device 4. In addition, since the rotation speed of the first roller shaft 71 is less than that of the winding device 6, the speed of the drive shaft device for driving the insulating paper is less than the speed of the winding device 6 for winding the insulating paper, so as to ensure that the insulating paper remains in a tightened state between the driving roller device 7 and the winding device 6.

[0031] In some embodiments, rubber layers are provided on both the first roller shaft 71 and the second roller shaft 72. This can improve the friction between the insulating paper between the first roller shaft 71 and the second roller shaft 72.

[0032] In some embodiments, the unwinding device 4 includes a first rotating shaft 40, a first disc 41 and a second disc 42. The first rotating shaft 40 is rotatably connected to the rotary damper 8. The middle part of the first disc 41 is fixed on the first rotating shaft 40. The middle part of the second disc 42 is detachably connected to the first rotating shaft 40. The first disc 41 and the second disc 42 are arranged at intervals along the length direction of the first rotating shaft 40.

[0033] During use, the second disc 42 is removed, the insulating paper roll to be wound is sleeved on the first rotating shaft 40, and then the second disc 42 is installed on the first rotating shaft 40 so that the first disc 41 and the second disc 42 clamp the insulating paper roll on the first rotating shaft 40.

[0034] In some embodiments, the second disc 42 is provided with a first connecting sleeve 420, and a through first threaded hole is provided on the side of the first connecting sleeve 420. The first rotating shaft 40 extends out of the first connecting sleeve 420, and a first fastening bolt is used to connect in the first threaded hole.

[0035] Specifically, a first circular hole is provided in the middle of the second disk 42. The first connecting sleeve 420 is aligned with the first circular hole and fixed in the middle of the second disk 42. During the installation of the second disk 42, the first rotating shaft 40 is passed through the first connecting sleeve 420, and then a first fastening bolt is inserted into the first threaded hole so that the first fastening bolt abuts against the first rotating shaft 40 to fix the second disk 42. When the second disk 42 needs to be disassembled, the first fastening bolt can be directly rotated out.

[0036] In some embodiments, the winding device 6 includes a second rotating shaft 60, a third disk 61 and a fourth disk 62. The second rotating shaft 60 is rotatably connected to the first vertical bracket 2. The middle of the third disk 61 is fixed to the second rotating shaft 60. The middle of the fourth disk 62 is detachably connected to the first rotating shaft 40. The third disk 61 and the fourth disk 62 are arranged at intervals along the length direction of the second rotating shaft 60.

[0037] In some embodiments, a second connecting sleeve 620 is provided on the fourth disk 62. A through second threaded hole is provided on the side of the second connecting sleeve 620. The second rotating shaft 60 extends out of the second connecting sleeve 620, and the second threaded hole is used to connect a second fastening bolt.

[0038] Specifically, a circular hole is provided in the middle of the fourth disk 62. The second connecting sleeve 620 is aligned with the first circular hole and fixed in the middle of the fourth disk 62. During the installation of the fourth disk 62, the second rotating shaft 60 is passed through the second connecting sleeve 620, and then a second fastening bolt is inserted into the second threaded hole so that the second fastening bolt abuts against the second rotating shaft 60 to fix the fourth disk 62. When the fourth disk 62 needs to be disassembled, the second fastening bolt can be directly rotated out.
