[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] ‌The transformer coil is an important component of the transformer, and its main function is to achieve the transmission of electrical energy and voltage conversion through the principle of electromagnetic induction.‌

[0039] The coil surface of the transformer is usually insulated to prevent the transformer coil from contacting the transformer structure or other electrical conductors, thereby causing leakage faults and affecting the safe operation of the transformer equipment.

[0040] In some embodiments, the coil of the transformer includes an electromagnetic wire and insulating paper wrapped around the surface of the electromagnetic wire, wherein the electromagnetic wire realizes the transmission of electric energy, and the insulation of the transformer coil can be achieved by wrapping the insulating paper.

[0041] Currently, transformer coil processing typically relies on manual application of insulating paper around the magnet wire. However, this method is inefficient and labor-intensive. Furthermore, manual operation can easily lead to uneven wrapping, compromising insulation performance and failing to meet production quality requirements.

[0042] To address the above technical issues, the present invention discloses a paper wrapping machine that can be used to wrap insulating paper around the surface of the electromagnetic wire of a coil. Because the wrapping process is mechanically completed, manual wrapping is unnecessary, effectively reducing labor intensity. Furthermore, wrapping the insulating paper using the paper wrapping machine ensures uniformity, maintains the insulation effect of the coil, and improves the quality of the coil.

[0043] like Figures 1 to 3 As shown, the paper wrapping machine disclosed in the embodiment of the present application includes: a mounting base 1, a guide member 2, a drive assembly 3, a tensioning assembly 4 and a wrapping paper storage assembly 5. The paper wrapping machine includes but is not limited to being used for wrapping insulating wire on the surface of electromagnetic wire during coil processing.

[0044] It should be noted that the electromagnetic wire in this article can be the wrapped part, and the insulating paper is the wrapping paper.

[0045] The mounting base 1 serves as the mounting base for the guide 2, the drive assembly, and the tensioning assembly 4. The specific structure and shape of the mounting base 1 can be set according to different needs and are all within the protection range. The mounting base 1 has a wire hole 12 that passes through the mounting base 1 along a first direction. The wire hole 12 is for the electromagnetic wire to pass through. It can be understood that the electromagnetic wire passes through the wire hole 12. Optionally, the wire hole 12 includes but is not limited to a circular hole, and the radial dimension of the wire hole 12 is larger than the radial dimension of the electromagnetic wire. The specific dimensions of the wire hole 12 can be set according to different needs and are all within the protection range.

[0046] In some embodiments, the guide member 2 and the mounting base 1 are arranged along a first direction and opposite the wire hole 12. In some embodiments, the guide member 2 has an arcuate structure, and the inner wall of the guide member 2 is concentric with the inner wall of the wire hole 12. This can be understood as: the axis of the guide member 2 coincides with the axis of the wire hole 12. Along the radial direction of the wire hole 12, the inner wall of the guide member 2 protrudes from the inner wall of the wire hole 12.

[0047] Combine Figure 3 and Figure 4 As shown, the guide member 2 has a guide groove 23 that penetrates the guide member 2 in the radial direction, and the guide groove 23 is used for passing the insulating paper 6.

[0048] The guide member 2 is connected to the drive assembly 3, which drives the guide member 2 to rotate about its own axis. This rotation of the guide member 2 simultaneously drives the insulating paper 6, which passes through the guide groove 23, to rotate about the axis of the guide member 2. Because the axis of the guide member 2 coincides with the axis of the wire hole 12, the guide member 2 drives the insulating paper 6 to rotate, allowing the insulating paper 6 to be wound circumferentially around the electromagnetic wire 7 within the wire hole 12.

[0049] The wrapping paper storage assembly 5 is installed on the mounting base 1, and insulating paper 6 is arranged in the wrapping paper storage assembly 5. Optionally, the insulating paper 6 includes but is not limited to being arranged in a roll, which can be understood as: the insulating paper 6 is an insulating paper roll.

[0050] The tensioning assembly 4 includes but is not limited to a tensioning wheel, which is rotatably mounted on the mounting seat 1 , and a plurality of tensioning wheels are arranged between the wrapping paper storage assembly 5 and the guide member 2 .

[0051] The insulating paper 6 of the wrapping paper storage assembly 5 can be wound around the tensioning assembly 4, and the end of the insulating paper 6 can pass through the guide slot 23 of the guide member 2. The setting of the tensioning assembly 4 can adjust the tensioning force of the insulating paper 6 wound between the wrapping paper storage assembly 5 and the guide member 2, thereby changing the winding force of the insulating paper 6 on the electromagnetic wire 7 during the process of winding the insulating paper 6 around the electromagnetic wire 7.

[0052] It should be noted that the paper wrapping machine disclosed in the embodiment of the present application utilizes the rotation of the guide member 2 to continuously pull the insulating paper 6 of the wrapping paper storage assembly 5 and continuously output it, and utilizes the guide groove 23 of the guide member 2 to limit and guide the passing insulating paper 6, so that the insulating paper 6 is wound on the electromagnetic wire 7 passing through the wire hole 12 of the mounting seat 1.

[0053] It should be noted that when using the above-mentioned paper wrapping machine, the operator needs to move the paper wrapping machine along the axis of the electromagnetic wire 7 so that the paper wrapping machine can continuously wind the electromagnetic wire 7 in the axial direction. The insulating paper 6 wrapped around the electromagnetic wire 7 is coated with adhesive on one side to ensure adhesion between the insulating paper 6 and the electromagnetic wire 7. The adhesive force between the insulating paper 6 and the electromagnetic wire 7 can be used to pull the insulating paper 6 of the wrapping paper storage assembly 5 to be continuously discharged during the rotation of the guide member 2.

[0054] like Figure 1 The guide member 2 shown includes a first plate 21 and a second plate 22 .

[0055] The first plate 21 and the second plate 22 are both arc-shaped plates, and are arranged along the circumference of the wire hole 12 . There is a gap between the first plate 21 and the second plate 22 , and the gap forms the guide groove 23 .

[0056] Combine Figure 2 and Figure 5 As shown, the first plate 21 and the second plate 22 are connected via a driving assembly 3 , and the driving assembly 3 can simultaneously drive the first plate 21 and the second plate 22 to rotate around the axial direction of the guide member 2 .

[0057] The driving assembly 3 includes a driving wheel 31 , a driven wheel 32 and a driving motor.

[0058] The driving wheel 31 and driven wheel 32 are rotatably mounted on the mounting base 1, and the drive motor is fixed to the mounting base 1. The mounting positions of the driving wheel 31 and the drive motor on the mounting base 1 can be adjusted according to different needs and are within the protection range. The driven wheel 32 is a ring gear, and the inner ring of the driven wheel 32 is opposite to the wire hole 12 of the mounting base 1. The guide member 2 is connected to the driven wheel 32. Specifically, the axis of the inner ring of the driven wheel 32 coincides with the axis of the wire hole 12.

[0059] In the embodiment of the present application, the driving wheel 31 is in transmission connection with the drive motor, i.e., the drive motor can drive the driving wheel 31 to rotate. Optionally, the driving wheel 31 is fixed to the output shaft of the drive motor. The driving wheel 31 meshes with the driven wheel 32. During the rotation of the driven wheel 32, the driven wheel 32 synchronously drives the guide member 2 to rotate about its axis.

[0060] In some embodiments, the distance between the first plate 21 and the second plate 22 along the circumference of the driven wheel 32 is adjustable, which can be understood as: the size of the guide groove 23 along the circumference of the wire hole 12 is adjustable.

[0061] The circumferential dimension of the guide groove 23 pressing through the wire hole 12 is adjustable, so that insulating papers 6 of different thicknesses can pass through the guide groove 23 , that is, the guide groove 23 can adapt to insulating papers 6 of different thicknesses.

[0062] Combine Figures 5 to 7 As shown, the paper wrapping machine further comprises an adjusting assembly 8 for adjusting the distance between the first plate 21 and the second plate 22 .

[0063] The adjustment assembly 8 includes a push rod 81 and a push rod base 82. A guide groove 321 is provided along the circumference of the driven wheel 32. The circumferential extension of the guide groove 321 along the driven wheel 32 can be adjusted to meet specific needs and remain within the protection range. In some embodiments, two adjustment assemblies 8 are provided, connected to the first plate 21 and the second plate 22 in a one-to-one correspondence.

[0064] The following content describes the connection relationship between the adjustment component 8 and the first plate 21 . The connection relationship between the other adjustment component 8 and the second plate 22 can be referred to the following description.

[0065] The push rod 81 is fixedly connected to the push rod base 82; the push rod base 82 is installed in the guide groove 321, and the push rod base 82 can move along the guide groove 321 and the push rod base 82 can be fixed in the guide groove 321; the push rod 81 is detachably connected to the first plate 21.

[0066] The push rod 81 includes but is not limited to a multi-link structure, and can certainly be a single link. One end of the push rod 81 is detachably connected to the first plate 21 via a threaded connector, and the other end of the push rod 81 is connected to the push rod base 82.

[0067] In some embodiments, a power motor is integrated in the push rod base 82 to realize the movement of the push rod base 82. For the method of realizing the movement of the push rod base 82 under the action of the internally integrated power motor, please refer to the structure of the existing power motor to realize the movement of the power motor installation structure, which will not be repeated here.

[0068] Based on the above technical solution, the embodiment of the present application further provides a laser rangefinder 11 for detecting the thickness of the insulating paper 6. The laser rangefinder 11 is mounted on the mounting base 1 and is in communication with the power motor integrated in the push rod base 82. After the laser rangefinder 11 detects the size of the insulating paper 6, it drives the push rod base 82 to move according to the measured size until the required size of the guide groove 321 is reached. The communication connection between the laser rangefinder 11 and the power motor enables automatic adjustment of the size of the guide groove 321.

[0069] It should be noted that: the paper wrapping machine of the present application is provided with a controller. After the laser rangefinder 11 detects the thickness of the insulating paper 6, the controller determines the required size of the guide groove 321 based on the detected thickness value, and compares the required size of the guide groove 321 with the actual size of the guide groove 321. When the actual size of the guide groove 321 is smaller than the required size of the guide groove 321, the push rod base 82 can be controlled to move away from the other push rod base 82; when the actual size of the guide groove 321 is larger than the required size of the guide groove 321, the push rod base 82 can be controlled to move toward the other push rod base 82.

[0070] The manner in which the controller determines the required size of the guide groove 321 according to the detected thickness value includes, but is not limited to, pre-storing the relationship between the thickness of the insulating paper 6 and the required size of the corresponding guide groove 321 in the controller.

[0071] The guide groove 321 is a snap-on guide rail. Specifically, a spring snap (not shown) is provided on the side wall of the guide groove 321. The side wall is in a direction intersecting with the extending direction of the guide groove 321. It can be understood that the side wall is the axial side wall of the driven wheel.

[0072] Optionally, multiple spring clips are provided on the sidewalls of the guide groove 321 along the circumference of the guide groove 321. When the push rod base 82 moves along the guide groove 321 to a position corresponding to the spring clip, the spring clip pops out and squeezes the push rod base 82, securing the push rod base 82 within the guide groove 321. The number and arrangement of the spring clips can be adjusted according to different needs and are all within the protection range.

[0073] In some embodiments, the spring buckle includes a spring (not shown) and a pressing plate (not shown).

[0074] One end of the spring is connected to the side wall of the guide groove 321, and the other end of the spring is fixedly connected to the extrusion plate. Optionally, at least one of the extrusion plate and the extrusion plate mounting position on the side wall of the guide groove 321 is an electromagnetic structure. In the initial position, the extrusion plate is connected to the side wall of the guide groove 321 by magnetic attraction, and the extrusion plate compresses the spring, which is in a compressed state. When the push rod base 82 moves to the corresponding position, the electromagnetic structure loses power, causing the connection between the extrusion plate and the guide groove 321 to fail. Under the action of the spring, the extrusion plate pops out and compresses the push rod base 82, causing the push rod base 82 to be fixed in the guide groove 321.

[0075] In some embodiments, the guide slot 321 is mounted on an electromagnetic structure, and the push rod base 82 is a metal structure. The push rod base 82 is provided with a controller that controls the power supply and discharge of the electromagnetic structure. The push rod base 82 is also provided with a sensor that is in communication with the controller. When the sensor detects the push rod base 82, the controller controls the electromagnetic structure to de-energize.

[0076] Those skilled in the art will appreciate that, in other optional embodiments, the push rod base 82 is an electromagnetic structure, and is provided with a controller for controlling the power supply and discharge of the electromagnetic structure. The guide groove 321 has a metal mounting position, and a sensor is provided at the mounting position. The sensor is communicatively connected with the controller. When the sensor detects the push rod base 82, the controller controls the electromagnetic structure to lose power.

[0077] The spring buckle has a simple structure and is easy to operate, and can realize automatic response without the need for manual operation, which is beneficial to reducing the labor intensity of the operator.

[0078] It should be noted that the push rod base 82 moves along the guide groove 321 to adjust the distance between the first plate 21 and the second plate 22. The spring clip of the guide groove 321 can limit the push rod base 82 to ensure that the push rod base 82 is fixed in the guide groove 321.

[0079] It should be noted that: when using the paper wrapping machine, the operator can adjust the position of the push rod base 82 in the guide groove 321 according to the thickness of the insulating paper 6, thereby adjusting the distance between the first plate 21 and the second plate 22, and then adjusting the size of the guide groove 23 along the circumference of the wire hole 12.

[0080] Optionally, during the process of adjusting the size of the guide groove 23 along the circumference of the wire hole 12, you can choose to adjust only the position of the first plate 21 or only the position of the second plate 22. Of course, you can also adjust the positions of the first plate 21 and the second plate 22 at the same time, and both are within the protection range.

[0081] like Figures 1 to 4 As shown, the tensioning assembly 4 of the embodiment of the present application includes a first tensioning wheel 41 and a second tensioning wheel 42 .

[0082] The first tensioning wheel 41 is rotatably mounted on the mounting base 1, and there are multiple first tensioning wheels 41, and the multiple first tensioning wheels 41 are not collinear. This can be understood as: the first tensioning wheel 41 is staggered in the direction of the line connecting the guide groove 23 and the material outlet 521 of the wrapping paper storage assembly 5. The surface of the first tensioning wheel 41 is processed with a spiral guide pattern with a depth of 0.3mm-1.0mm. By providing the spiral guide pattern, the friction between the insulating paper 6 and the surface of the first tensioning wheel 41 can be reduced, thereby reducing the wear of the insulating paper 6 and the first tensioning wheel 41.

[0083] In some embodiments, other patterns that can reduce the friction between the first tensioning wheel 41 and the insulating paper 6 can be provided on the surface of the first tensioning wheel 41, and all of them are within the protection range.

[0084] The paper wrapping machine disclosed in the embodiment of the present application is further provided with a pressure sensor for monitoring the pressure of the insulating paper 6 on the first tensioning wheel 41 , so as to monitor the tensioning force of the insulating paper 6 on the first tensioning wheel 41 .

[0085] The second tensioning wheel 42 is rotatably mounted on the driven wheel 32. This means that the second tensioning wheel 42 rotates synchronously with the driven wheel 32 and is also capable of rotating about its own axis. This means that the second tensioning wheel 42 can rotate both on its own axis and about the axis of the driven wheel 32. Optionally, there can be one or more second tensioning wheels 42. The second tensioning wheel 42 and the guide groove 23 are arranged radially along the driven wheel 32.

[0086] It should be noted that the second tensioning wheel 42 rotates with the driven wheel 32 to guide the insulating paper 6, ensuring that the insulating paper 6 can be stably transported to the guide groove 23, and can ensure the transport direction of the insulating paper 6 to the guide groove 23, thereby ensuring the tension of the insulating paper 6.

[0087] Optionally, the push rod 81 is a multi-link structure, and the push rod 81 includes a connecting rod extending radially from the driven wheel 32. By rotating the position of the connecting rod, the distance between the first plate 21 and the second plate 22 and the center of the circle can be adjusted, thereby changing the distance between the guide member 2 and the second tensioning wheel 42, and then changing the tensioning force of the insulating paper 6, so as to improve the bonding stability of the insulating paper 6 to the electromagnetic wire 7.

[0088] like Figures 1 to 3 As shown, the wrapping paper storage assembly 5 includes: an infrared detection module 51 , a box body 52 , a reel 53 , a reel 54 and a handle 55 .

[0089] The box body 52 includes but is not limited to an openable closed structure to ensure the cleanliness of the insulating paper 6 in the box body 52 .

[0090] A reel 53 is disposed within the housing 52, and a reel 54 is disposed on the reel 53. The reel 54 is rotatably disposed relative to the housing 52. Alternatively, the reel 53 may be rotatably disposed within the housing 52, and the reel 54 may be circumferentially fixedly sleeved on the reel 53; or the reel 53 may be fixed within the housing 52, and the reel 54 may be rotatably sleeved on the reel 53.

[0091] The insulating paper 6 is wound on the reel 54 , so that a roll of the insulating paper 6 is formed on the reel 54 .

[0092] A material outlet 521 is provided at a position of the box body 52 arranged toward the first tensioning wheel 41 . The insulating paper 6 passes through the box body 52 through the material outlet 521 and is wound around the first tensioning wheel 41 .

[0093] An infrared detection module 51 is installed at the material outlet 521 of the box 52. This infrared detection module 51 is used to detect whether insulation paper 6 is present at the material outlet 521. When the infrared detection module 51 detects that no insulation paper 6 has passed through the material outlet 521, the infrared detection module 51 triggers the wrapping machine's alarm device, reminding the operator to end the wrapping operation. Optionally, the alarm device includes, but is not limited to, an audible and visual alarm device, and is communicatively connected to the infrared detection module 51.

[0094] In some embodiments, the infrared detection module 51 can also be communicated with the drive motor that drives the active wheel 31 to rotate.
