Technical Field

[0001] This application relates to the field of insulating paper processing technology, and in particular to a forming mechanism for the surface of insulating paper. Background Technology

[0002] Currently, insulating paper is a key insulating material used to isolate conductive parts inside motors, prevent current leakage or short circuits, and provide protection against high temperatures, mechanical stress, and chemical corrosion. Common insulating paper materials include DuPont paper (Nomex), electrical paper, polyester film paper (Mylar), and mica paper, each with different dielectric strengths, heat resistance ratings, and mechanical properties, suitable for various applications such as medium and low voltage motors, high-performance motors, and special motors. Through high dielectric strength and excellent thermal aging performance testing, insulating paper can significantly improve the reliability and service life of motors.

[0003] Before the insulating paper is inserted into the winding groove, it needs to be shaped. During the shaping process, the workers fold the insulating paper according to the size of the winding groove so that it can be bent and inserted into the winding groove.

[0004] Regarding the aforementioned technologies, the inventors believe that in addition to having good insulation properties, insulating paper also has good mechanical strength. Therefore, there is a problem that the insulating paper is prone to springing back after being bent, which affects the working efficiency of inserting the insulating paper into the winding groove.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Furthermore, the drive assembly includes a drive motor mounted on the frame, a first rotating shaft is provided on the frame, the first forming roller is mounted on the first rotating shaft, and the output shaft of the drive motor is connected to the first rotating shaft.

[0009] Furthermore, a pressure strip is formed on the first forming roller, and a pressure groove is formed on the second forming roller, with the pressure strip engaging with the pressure groove.

[0010] Furthermore, the frame is provided with a guide groove, the adjustment component includes a guide block, the guide block is slidably installed in the guide groove, a second rotating shaft is provided on the guide block, the second rotating shaft is rotatably installed on the guide block, and the second forming roller is rotatably installed on the second rotating shaft.

[0013] Furthermore, the frame is provided with a conveyor rail, and a conveyor channel is formed on the conveyor rail, through which the insulating paper passes.

The output shaft of the drive motor 21 is connected to the first rotating shaft 22, and the drive motor 21 drives the first rotating shaft 22 to rotate. A first forming roller 11 is mounted on the first rotating shaft 22. In use, the drive motor 21 drives the first forming roller 11 to rotate via the first rotating shaft 22.

[0027] Reference Figures 2-3The frame 1 has a guide groove 13 with a rectangular cross-section, and one side of the guide groove 13 is open along its length. The adjusting assembly 3 includes a guide block 31, which is slidably installed in the guide groove 13. A second rotating shaft is provided on the guide block 31. Furthermore, a bearing 32 is provided on the second rotating shaft, and the second forming roller 12 is rotatably installed on the second rotating shaft via the bearing 32. In use, the insulating paper passes between the first forming roller 11 and the second forming roller 12.

[0028] Reference Figure 3 Furthermore, since different insulating papers have different thicknesses, in order for the first forming roller 11 and the second forming roller 12 to press firmly against the insulating paper, an adjusting rod 33 is provided on the frame 1. The adjusting rod 33 is threadedly connected to the frame 1, and one end of the adjusting rod 33 passes through the guide groove 13. An adjusting block 34 is installed on the end of the adjusting rod 33 that passes through the guide groove 13. The adjusting block 34 is rotatably mounted on the adjusting rod 33, and one end of the adjusting block 34 is engaged with the guide block 31. In use, rotating the adjusting rod 33 adjusts the position of the guide block 31 in the guide groove 13 through the adjusting block 34, so that the second forming roller 12 can press firmly against the first forming roller 11.

[0029] Furthermore, a support groove 14 is provided on the side of the frame 1 relative to the adjusting block 34 on the guide block 31. A support spring 141 is installed in the support groove 14 of the frame 1, and the support spring 141 is embedded in the support groove 14.

In use, the pressure strip 111 on the first forming roller 11 is embedded into the pressure groove 121 of the second forming roller 12. In addition, the pressure strip 111 and the pressure groove 121 are spaced apart to prevent damage to the insulating paper during the pressing process of the pressure strip 111.
