Description

Technical Field

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

[0002] Insulating paper is a crucial insulating material used to isolate conductive parts inside motors, preventing current leakage or short circuits, and providing 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 low- and medium-voltage motors, high-performance motors, and special-purpose motors. Through high dielectric strength and excellent thermal aging performance testing, insulating paper can significantly improve the reliability and service life of motors.

[0003] Traditional electrical paper or wood pulp insulating paper has a certain degree of hygroscopicity. When it gets damp, the dielectric strength, mechanical strength, and withstand voltage of the insulating paper will decrease, which may lead to insulation failure, short circuit, or breakdown in motors.

[0004] A Chinese patent with publication number CN203660825U discloses an insulating paper heating device for a paper insertion device, comprising an insulating paper carrying rail for carrying insulating paper, an insulating paper heating part provided on the insulating paper carrying rail, and a channel between the insulating paper carrying rail and the insulating paper heating part allowing the insulating paper to pass through; the insulating paper carrying rail is horizontally slidably disposed on a base, and a horizontal movement driving device is provided on the side of the insulating paper carrying rail to drive the insulating paper carrying rail to slide horizontally on the base.

[0005] In related technologies, a horizontal sliding drive device drives the insulating paper carrier rail to slide horizontally on the base, the insulating paper passes through the insulating paper carrier rail, and the insulating paper heating part heats the insulating paper.

[0006] Regarding the aforementioned technologies, the inventors believe that if the insulating paper is heated unevenly during processing as it passes through the heating section, it will affect the normal use of the insulating paper. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a heating mechanism for insulating paper, which solves the technical problem that if the insulating paper is not heated evenly during the processing when it passes through the heating part, it will affect the normal use of the insulating paper.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A heating mechanism for insulating paper includes: a support for supporting the heating mechanism; an unwinding assembly mounted on the support, on which insulating paper is wound, the unwinding being used to unwind the insulating paper; a heating assembly mounted on the side of the support near the unwinding assembly, through which the insulating paper passes; a flattening assembly mounted on the side of the support near the heating assembly; and a guide assembly mounted on the support for guiding the insulating paper through the heating assembly and the flattening assembly.

[0010] Furthermore, the unwinding assembly includes a mounting shaft, which is rotatably mounted on the bracket. A drive motor is mounted on the bracket, and the output shaft of the drive motor is connected to the mounting shaft. A rotating disk is mounted on the mounting shaft, and a rotating groove is formed on the rotating disk. The insulating paper roll is disposed in the rotating groove.

[0011] Furthermore, the guiding assembly includes a guide roller, which is rotatably mounted on the bracket. A limit rod is provided on the side of the bracket near the guide roller, and the limit rod is arranged parallel to and spaced apart from the guide roller.

[0012] Furthermore, the heating assembly includes two support rails spaced apart, forming a heating channel between the two support rails. Each support rail has an installation groove that communicates with the heating channel. A heating rod is installed in the installation groove of the support rail, and the heating rod heats the heating channel.

[0013] Furthermore, the bearing rail has guide arc surfaces at both ends of the heating channel, with the guide arc surfaces facing the side closer to the heating channel.

[0014] Furthermore, a protective cover is installed on the bracket, the protective cover is placed on the support rail, and the protective cover has ventilation holes spaced apart.

[0015] Furthermore, the bracket is provided with a limiting plate and a limiting block, the limiting plate is installed on the bracket, and the insulating paper passes through the space between the limiting plate and the limiting block.

[0016] In summary, this application includes at least one of the following beneficial technical effects of the heating mechanism for insulating paper:

[0017] 1. The insulating paper roll is placed on the unwinding assembly. During use, the unwinding assembly unwinds the insulating paper. One end of the insulating paper passes through the heating assembly and the flattening assembly in sequence via the guide assembly. The heating assembly heats the insulating paper. After the insulating paper is heated, the flattening assembly flattens the insulating paper. The unwinding of the insulating paper unwinding assembly and the setting of the flattening assembly can improve the heating efficiency of the insulating paper, make the heating of the insulating paper more uniform, and enable the insulating paper to be used normally.

[0018] 2. Two support rails are set at intervals through guide rollers to ensure that the insulating paper is heated more thoroughly;

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0026] This application discloses a heating mechanism for insulating paper.

[0027] Reference Figure 1 A heating mechanism for insulating paper includes a support 1, on which an unwinding assembly 2, a heating assembly 3, and a guide assembly 4 are provided. The insulating paper roll is placed on the unwinding assembly 2. In use, one end of the insulating paper passes through the heating assembly 3 under the action of the guide assembly 4, and the heating assembly 3 heats the insulating paper.

[0028] Reference Figure 2 The unwinding assembly 2 includes a mounting shaft 21 and a drive motor 22. The drive motor 22 is mounted on the bracket 1, and the mounting shaft 21 is rotatably mounted on the bracket 1. One end of the output shaft of the drive motor 22 is connected to the mounting shaft 21. In use, the drive motor 22 drives the mounting shaft 21 to rotate.

[0029] A rotating disk 23 is mounted on the mounting shaft 21. During use, the rotating disk 23 is locked onto the mounting shaft 21. The drive motor 22 drives the rotating disk 23 on the mounting shaft 21 to rotate. As the drive motor 22 rotates, the rotating disk 23 rotates on the mounting shaft 21. The rotating disk 23 has a rotating groove 231, which is generally annular. Insulating paper is rolled within the rotating groove 231 of the rotating disk 23. As the rotating disk 23 rotates, the insulating paper is released from the rotating disk 23.

[0030] Reference Figure 3 The heating component 3 includes a support rail 31, which is rectangular in shape. Two support rails 31 are spaced apart along the thickness direction and are parallel to each other. A heating channel 32 is formed between the two support rails 31, and the heating channel 32 is parallel to the length direction of the support rail 31. In use, one end of the insulating paper is inserted into the support rail 31 from one end along its length direction, and after passing through the support rail 31, the insulating paper exits from the other side of the support rail 31.

[0031] The insulating paper is inserted from one end of the support rail 31. The insulating paper is prone to rubbing against the end face of the support rail 31. If this rubbing occurs, the local thickness of the insulating paper will decrease, potentially leading to electrical breakdown during use. To reduce this rubbing, guide arc surfaces 33 are formed at both ends of the support rail 31 along its length, with the guide arc surfaces 33 facing towards the heating channel 32. During use, the guide arc surfaces 33 guide the insulating paper, thereby reducing rubbing between the insulating paper and the support rail 31.

[0032] Mounting grooves 34 are provided on the adjacent sides of the bearing rails 31. Several mounting grooves 34 are spaced apart on the corresponding bearing rails 31, and each mounting groove 34 communicates with the heating channel 32. Heating rods 35 are installed within each of the mounting grooves 34 of the bearing rails 31, and the heating rods 35 heat the insulating paper passing through the bearing rails 31. Because the heating rods 35 are embedded within the mounting grooves 34 of the bearing rails 31, contact between the insulating paper and the heating rods 35 is avoided, preventing overheating of the insulating paper. Simultaneously, since the insulating paper passes between two bearing rails 31, the heating plate heats both sides of the insulating paper in the thickness direction, improving the heating effect of the insulating paper.

[0033] Furthermore, since the heating rod 35 inside the support rail 31 continuously releases heat, there is a risk of burns if workers come into contact with the support rail 31. Therefore, a protective cover 11 is provided on the bracket 1, which covers the support rail 31. The protective cover 11 also has several vent holes 12 spaced apart. In use, the protective cover 11 protects the support rail 31, while the vent holes 12 maintain its permeability, allowing moisture generated by the heating of the insulating paper to dissipate into the air through the vent holes 12.

[0034] Reference Figure 1 The two support rails 31 are horizontally arranged. To improve the stability of the insulating paper passing through the support rails 31, the guide assembly 4 includes guide rollers 41, one on each side of the support rail 31 along its length. The two guide rollers 41 are rotatably mounted on the bracket 1. One end of the insulating paper passes under the guide roller 41 on the left side of the support rail. After passing through the heating channel 32, the insulating paper passes over the guide roller 41 on the right side of the support rail 31. Guided by the two guide rollers 41, the portion of the insulating paper passing through the support rail 31 remains horizontal, thereby reducing friction between the insulating paper and the support rail 31 and greatly improving the performance of the insulating paper.

[0035] Furthermore, a limiting rod 42 is provided on the bracket 1, which corresponds to the guide roller 41 and is arranged parallel to the guide roller 41 at intervals. The insulating paper passes through the guide roller 41 and the limiting rod 42, and the limiting rod 42 limits the insulating paper, thereby improving the convenience of the insulating paper passing through the guide roller 41.

[0036] During transport, the insulating paper is prone to warping on both sides. If its position is not adjusted promptly, it is easily damaged. Therefore, a limiting plate 13 is provided on the support 1, a guide groove 14 is provided on the support 1, and an adjusting bolt 15 is provided on the support 1. One end of the adjusting bolt 15 passes through the guide groove 14 and connects to the limiting plate 13. In use, the position of the limiting plate 13 on the support 1 is adjusted by adjusting the adjusting bolt 15. A limiting block 16 is provided on the limiting plate 13, and the limiting block 16 is installed on the limiting plate 13 with a gap between it and the limiting plate 13. The insulating paper passes between the limiting block 16 and the limiting plate 13. The setting of the limiting plate 13 and the limiting block 16 reduces the warping of the insulating paper on both sides during transport, thereby improving the stability of the insulating paper transport.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
