[0042] Example 1:

[0043] This embodiment provides an insulating paper rewinding machine, comprising:

[0044] The frame 1 is equipped with a winding roller 2 and multiple unwinding rollers 3;

[0045] The oven mechanism 4 is installed between the winding roller 2 and the unwinding roller 3 and is used to heat the insulating paper output by the unwinding roller 3;

[0046] The shaping mechanism 5 is installed between the oven mechanism 4 and the winding roller 2 and is used for shaping the insulating paper;

[0047] Among them, multiple unwinding rollers 3 output insulating paper of various specifications, and the winding roller 2 rewinds the insulating paper of various specifications into insulating paper rolls. The temperature in the drying oven mechanism 4 can be 105°C-125°C, but different temperature ranges can be used according to different insulating papers, specifically depending on the type of insulating paper. Therefore, the temperature needs to ensure that it does not affect the performance of the insulating paper. Temperature control is an existing mature technology and will not be described here.

[0048] At the same time, a driving device is also provided at the winding roller 2, and the installation position and specific structure of the driving device are existing mature technologies and will not be described here.

[0049] It can be seen from this embodiment that by setting multiple unwinding rollers 3 and winding rollers 2, multiple insulating papers of different specifications are rewound and wound onto the same winding roller 2 to meet customer needs, improve customer assembly efficiency and the competitiveness of insulating paper products, and after the unwinding roller 3 outputs the insulating paper, it is heated by the oven mechanism 4 and shaped by the shaping mechanism 5 to eliminate the bending that exists when the insulating paper roll is just unwound, improve the rewinding effect, ensure the quality of the rewound product, further meet customer needs, and improve product competitiveness.

[0050] Example 2:

[0051] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The oven mechanism 4 includes:

[0052] The box body 40 is mounted on the frame 1 and is provided with a slot 41 for the insulating paper to pass through;

[0053] The hot air assembly is mounted on the rack 1 and is located at the lowest point in the box 40;

[0054] An air outlet 42 is formed at the top of the box body 40 .

[0055] It can be seen from this embodiment that by heating with hot air, drying is ensured and the insulation paper is not affected. The air outlet 42 facilitates the discharge of the hot air after heating, ensuring uniform heating of the insulation paper.

[0056] Example 3:

[0057] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The hot air component includes:

[0058] The heating tube group 43 is installed in the box 40 and is located below the insulating paper;

[0059] The fan 44 is installed in the box 40 and is located below the heating tube group 43;

[0060] The windshield 45 is installed in the box 40 and is located above the heating tube group 43. It has air vents 46 on both sides along the direction of movement of the insulating paper.

[0061] The heating tube group 43 may be an electric heating tube, and the specific structure is an existing mature technology and will not be described in detail here.

[0062] It can be seen from this embodiment that the wind shield 45 can prevent the hot air from blowing directly onto the insulating paper closest to it, further avoiding the impact on the insulating paper, and the fan 44 drives the hot air into the box 40 through two air vents 46 and is located at the insulating paper. By heating the environment inside the box 40, the insulating paper is heated, effectively ensuring the uniformity of heating of the insulating paper.

[0063] Example 4:

[0064] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The shaping mechanism 5 includes:

[0065] A plurality of guide rollers 50 are mounted on the frame 1 and are used to change the feeding direction of the insulating paper.

[0066] The first pressing roller 51 is mounted on the frame 1 and cooperates with the guide roller 50 to flatten and shape the heated insulating paper.

[0067] It can be seen from this embodiment that the heated insulating paper is flattened by the first pressing roller 51, eliminating the bending existing when the insulating paper roll is just unwound, improving the product quality after the insulating paper is rewound, and further improving product competitiveness.

[0068] Example 5:

[0069] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features:

[0070] The clamping mechanism 6 is installed on the side of the winding roller 2 and is used to abut the tail end of the insulating paper on the winding roller 2.

[0071] It can be seen from this embodiment that the tail ends of multiple layers of insulating paper of different specifications on the winding roller 2 are abutted by the clamping mechanism 6, which makes it convenient for the staff to seal and fix the tail ends, thereby avoiding the tail end of the insulating paper being separated from the winding roller, which in turn causes the multiple layers of insulating paper outside the winding roller to spread out, thereby avoiding affecting the rewinding effect of the insulating paper and improving convenience.

[0072] Example 6:

[0073] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The clamping mechanism 6 includes:

[0074] The second pressing roller 60 is installed on the side of the winding roller 2 and abuts against the surface of the winding roller 2;

[0075] The bearing seat 61 is connected to both ends of the second pressure roller 60 in the axial direction, and a spring 62 is provided between the bearing seat 61 and the frame 1;

[0076] The spring 62 is in a compressed state.

[0077] It can be seen from this embodiment that the arrangement of the second pressure roller 60 and the spring 62 makes it easy to keep the second pressure roller 60 in contact with the surface of the winding roller 2 at all times, preventing the multi-layer insulation paper from spreading and improving the rewinding effect. In addition, the arrangement of the bearing seat 61 enables the second pressure roller 60 to follow the rotation, avoiding the influence of the rewinding effect of the insulation paper due to large friction.

[0078] Example 7:

[0079] This embodiment provides an insulating paper rewinding machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The clamping mechanism 6 also includes:

[0080] The guide plate 63 is mounted on the frame 1 and is used to guide the second pressing roller 60 when it moves away from or close to the winding roller 2.

[0081] It can be seen from this embodiment that, by setting the guide plate 63, the stability of the second pressure roller 60 when it moves due to the increase of the insulating paper wound by the winding roller 2 and the compression spring 62 is improved, thereby avoiding deviation, ensuring that the second pressure roller 60 abuts against the insulating paper, and preventing the multi-layer insulating paper outside the winding roller 2 from spreading, thereby improving product quality and further ensuring product competitiveness.

[0082] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
