Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0025] The coil of the transformer is an important part of the transformer, and its main function is to achieve the transmission of electrical energy and the transformation of voltage through the principle of electromagnetic induction. The surface of the coil of the transformer is usually insulated to prevent the coil of the transformer from coming into contact with the transformer structure or other electrical conductors, resulting in a leakage fault and affecting the safe operation of the transformer equipment.

[0026] In some embodiments, the coil of the transformer includes electromagnetic wire and insulating paper wrapped on the surface of the electromagnetic wire. Among them, the electromagnetic wire realizes the transmission of electrical energy, and the insulation of the coil of the transformer can be achieved by wrapping the insulating paper.

[0027] Currently, during the processing of the coil of the transformer, it is usually dependent on manual wrapping of the insulating paper on the surface of the electromagnetic wire. However, the method of manual wrapping of the insulating paper has low processing efficiency and high labor intensity; in addition, manual operation is prone to uneven wrapping of the insulating paper, affecting the insulation effect and unable to meet the requirements of production quality.

[0028] Based on the above technical problems, the embodiment of the present application discloses a paper wrapping machine. By using this paper wrapping machine, insulating paper can be wrapped on the surface of the electromagnetic wire of the coil. Since the process of wrapping the insulating paper is completed by a mechanical structure and does not require manual wrapping, the labor intensity is effectively reduced. In addition, by using the paper wrapping machine to wrap the insulating paper, the uniformity of the wrapping of the insulating paper can be ensured, the insulation effect of the coil can be guaranteed, and the quality of the coil can be improved.

[0029] As Figures 1 to 3 shown, the paper wrapping machine disclosed in the embodiment of the present application includes: a mounting base 1, a guiding member 2, a driving assembly 3, a tensioning assembly 4, and a wrapping paper storage assembly 5. This paper wrapping machine includes but is not limited to wrapping insulating wire on the surface of the electromagnetic wire during the coil processing.

[0030] It should be noted that: the magnet wire in this text can be the wrapped part, and the insulating paper is the wrapping paper.

[0031] Among them, the mounting base 1 is the mounting foundation for the guiding member 2, the driving 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 scope. The mounting base 1 has a wire passing hole 12 that penetrates the mounting base 1 in the first direction, and the magnet wire passes through the wire passing hole 12. It can be understood that: the magnet wire passes through the wire passing hole 12. Optionally, the wire passing hole 12 includes but is not limited to a circular hole, and the size of the wire passing hole 12 in the radial direction is greater than the size of the magnet wire in the radial direction. The specific size of the wire passing hole 12 can be set according to different needs and is all within the protection scope.

[0032] In some embodiments, the guiding member 2 and the mounting base 1 are arranged in the first direction and are arranged opposite to the wire passing hole 12. In some embodiments, the guiding member 2 is an arc-shaped structure, and the inner wall of the guiding member 2 is concentric with the inner wall of the wire passing hole 12. It can be understood that: the axis of the guiding member 2 coincides with the axis of the wire passing hole 12. Along the radial direction of the wire passing hole 12, the inner wall of the guiding member 2 protrudes from the inner wall of the wire passing hole 12.

[0033] Combined Figure 3 and Figure 4 As shown, the guiding member 2 has a guiding groove 23 that penetrates the guiding member 2 in the radial direction, and the insulating paper 6 is passed through the guiding groove 23.

[0034] The guiding member 2 is connected to the driving assembly 3, and the driving assembly 3 drives the guiding member 2 to rotate around its own axis. During the rotation of the guiding member 2, the insulating paper 6 passed through the guiding groove 23 can be driven to rotate synchronously around the axis of the guiding member 2. Since the axis of the guiding member 2 coincides with the axis of the wire passing hole 12, during the process of the guiding member 2 driving the insulating paper 6 to rotate, the circumferential winding of the insulating paper 6 around the magnet wire 7 in the wire passing hole 12 can be realized.

[0035] The wrapping paper storage assembly 5 is installed on the mounting base 1, and the 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. It can be understood that: the insulating paper 6 is an insulating paper roll.

[0036] The tensioning assembly 4 includes but is not limited to a tensioning wheel. The tensioning wheel is rotatably installed on the mounting base 1, and a plurality of tensioning wheels are arranged between the wrapping paper storage assembly 5 and the guiding member 2.

[0037] 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 guiding groove 23 of the guiding member 2. The setting of the tensioning assembly 4 can adjust the tension of the insulating paper 6 wound between the wrapping paper storage assembly 5 and the guiding member 2, so as to change the winding force of the insulating paper 6 on the magnet wire 7 during the winding process of the insulating paper 6 around the magnet wire 7.

[0038] It should be noted that: for the wrapping paper machine disclosed in the embodiments of the present application, by rotating the guiding member 2, the insulating paper 6 of the wrapping paper storage assembly 5 can be continuously pulled out, and the guiding groove 23 of the guiding member 2 is used to limit and guide the passing insulating paper 6, so that the insulating paper 6 is wound around the electromagnetic wire 7 passing through the wire passing hole 12 of the mounting seat 1.

[0039] It should be noted that: during the use of the above wrapping paper machine, the operator needs to move the wrapping paper machine along the axis of the electromagnetic wire 7 so that the wrapping paper machine can continuously wind in the axial direction of the electromagnetic wire 7. An adhesive is coated on one side of the insulating paper 6 wound around the electromagnetic wire 7 to bond the insulating paper 6 to the electromagnetic wire 7, and by using the adhesive force between the insulating paper 6 and the electromagnetic wire 7, the insulating paper 6 of the wrapping paper storage assembly 5 can be continuously pulled out during the rotation of the guiding member 2.

[0040] As Figure 1 shown, the guiding member 2 includes: a first plate 21 and a second plate 22.

[0041] Wherein, both the first plate 21 and the second plate 22 are arc-shaped plates, and the first plate 21 and the second plate 22 are arranged circumferentially along the wire passing hole 12. There is a gap between the first plate 21 and the second plate 22, and this gap forms the above-mentioned guiding groove 23.

[0042] Combined Figure 2 and Figure 5 shown, the first plate 21 and the second plate 22 are connected by a driving assembly 3, and the driving assembly 3 can drive the first plate 21 and the second plate 22 to rotate around the axis of the guiding member 2 simultaneously.

[0043] The driving assembly 3 includes: a driving wheel 31, a driven wheel 32 and a driving motor.

[0044] Wherein, the driving wheel 31 and the driven wheel 32 are rotatably installed on the mounting seat 1, and the driving motor is fixed on the mounting seat 1. The installation positions of the driving wheel 31 and the driving motor on the mounting seat 1 can be set according to different needs, and are all within the protection scope. The driven wheel 32 is an annular gear, and the inner ring of the driven wheel 32 is opposite to the wire passing hole 12 of the mounting seat 1, and the guiding 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 passing hole 12.

[0045] The driving wheel 31 of the embodiments of the present application is in transmission connection with the driving motor, that is, the driving motor can drive the driving wheel 31 to rotate. Optionally, the driving wheel 31 is fixed on the output shaft of the driving motor. The driving wheel 31 and the driven wheel 32 are in meshing transmission. During the rotation of the driven wheel 32, the driven wheel 32 synchronously drives the guiding member 2 to rotate around the axis of the guiding member 2.

[0046] In some embodiments, along the circumferential direction of the driven wheel 32, the distance between the first plate 21 and the second plate 22 is adjustable, which can be understood as: the dimension of the guiding groove 23 along the circumferential direction of the wire passing hole 12 is adjustable.

[0047] The dimension of the guiding groove 23 pressing over the circumferential direction of the wire passing hole 12 is adjustable, which can enable insulating papers 6 with different thicknesses to pass through the guiding groove 23, that is, the guiding groove 23 can adapt to insulating papers 6 with different thicknesses.

[0048] Combined with Figures 5 to 7 As shown, the paper wrapping machine further includes an adjusting assembly 8 for adjusting the distance between the first plate 21 and the second plate 22.

[0049] The adjusting assembly 8 includes: a push rod 81 and a push rod base 82. The driven wheel 32 is provided with a guiding groove 321 along the circumferential direction. The dimension of the guiding groove 321 extending along the circumferential direction of the driven wheel 32 can be set according to different needs and is within the protection scope. In some embodiments, there are two adjusting assemblies 8, and they are connected to the first plate 21 and the second plate 22 in a one-to-one correspondence.

[0050] The following content will be described by taking the connection relationship between the adjusting assembly 8 and the first plate 21 as an example. For the connection relationship between the other adjusting assembly 8 and the second plate 22, refer to the following description.

[0051] The push rod 81 is fixedly connected to the push rod base 82; the push rod base 82 is installed in the guiding groove 321, and the push rod base 82 can move along the guiding groove 321 and can be fixed in the guiding groove 321; the push rod 81 is detachably connected to the first plate 21.

[0052] The push rod 81 includes but is not limited to a multi-link structure, and of course it can also be a single link. One end of the push rod 81 is detachably connected to the first plate 21 through a threaded connector, and the other end of the push rod 81 is connected to the push rod base 82.

[0053] In some embodiments, a power motor is integrated in the push rod base 82, which can realize the movement of the push rod base 82. For the way to realize the movement of the push rod base 82 under the action of the power motor integrated inside, reference can be made to the existing structure of the power motor to realize the walking of the power motor installation structure, which will not be elaborated here.

[0054] Based on the above technical solutions, an embodiment of the present application further sets a laser rangefinder 11 for detecting the thickness of the insulating paper 6. The laser rangefinder 11 is installed on the mounting seat 1, and the laser rangefinder 11 is communicatively connected to 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 size of the guiding groove 321 that meets the requirements is reached. The communicative connection between the laser rangefinder 11 and the power motor can realize the automatic adjustment of the size of the guiding groove 321.

[0055] It should be noted that the wrapper machine of this 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 guiding groove 321 according to the detected thickness value, and compares the required size of the guiding groove 321 with the actual size of the guiding groove 321. When the actual size of the guiding groove 321 is smaller than the required size of the guiding groove 321, the controller can control the push rod base 82 to move away from the other push rod base 82; when the actual size of the guiding groove 321 is larger than the required size of the guiding groove 321, the controller can control the push rod base 82 to move closer to the other push rod base 82.

[0056] The ways for the controller to determine the required size of the guiding groove 321 according to the detected thickness value include, but are not limited to, that the relationship between the thickness of the insulating paper 6 and the required size of the corresponding guiding groove 321 is pre-stored in the controller.

[0057] The guiding groove 321 is a snap-on guide rail. Specifically, spring snaps (not shown in the figure) are provided on the side wall of the guiding groove 321, and this side wall is in a direction intersecting with the extending direction of the guiding groove 321. It can be understood that this side wall is the side wall in the axial direction of the driven wheel.

[0058] Optionally, a plurality of spring snaps are arranged along the circumferential direction of the side wall of the guiding groove 321. When the push rod base 82 moves along the guiding groove 321 to the position of the corresponding spring snap, the spring snap will pop out and squeeze the push rod base 82, so that the push rod base 82 is fixed in the guiding groove 321. The number and arrangement position of the spring snaps can be set according to different needs, and all are within the protection scope.

[0059] In some embodiments, the spring snap includes a spring (not shown in the figure) and a pressing plate (not shown in the figure).

[0060] Wherein, one end of the spring is connected to the side wall of the guiding groove 321, and the other end of the spring is fixedly connected to the pressing plate. Optionally, at least one of the installation positions of the pressing plate and the side wall of the guiding groove 321 of the pressing plate is an electromagnetic structure. In the initial position, the pressing plate is connected to the side wall of the guiding groove 321 by magnetic adsorption, and the pressing plate squeezes the spring, and the spring is in a compressed state; when the push rod base 82 moves to the corresponding position, the electromagnetic structure loses power, so that the connection between the pressing plate and the guiding groove 321 fails, and under the action of the spring, the pressing plate pops out and squeezes the push rod base 82, so that the push rod base 82 is limited and fixed in the guiding groove 321.

[0061] In some embodiments, the installation position of the guiding groove 321 is an electromagnetic structure, and the push rod base 82 is a metal structure. A controller for controlling the energization and de-energization of the electromagnetic structure is provided on the push rod base 82, and a sensor is also provided on the push rod base 82. The sensor is communicatively connected to the controller. When the sensor detects the push rod base 82, the controller controls the electromagnetic structure to lose power.

[0062] Those skilled in the art can understand that in other alternative embodiments, the push rod base 82 is an electromagnetic structure, and a controller for controlling the energization and de-energization of the electromagnetic structure is provided. The guiding groove 321 has a metal installation position, and a sensor is provided at the installation position. The sensor is communicatively connected to the controller. When the sensor detects the push rod base 82, the controller controls the electromagnetic structure to lose power.

[0063] The above spring buckle structure is simple and easy to operate, can achieve automatic response, does not require manual operation, and is beneficial to reducing the labor intensity of the operator.

[0064] It should be noted that: the push rod base 82 moves along the guiding groove 321, and the distance between the first plate 21 and the second plate 22 can be adjusted. The spring buckle of the guiding groove 321 can limit the push rod base 82 to ensure the fixation of the push rod base 82 in the guiding groove 321.

[0065] It should be noted that: during the use of the paper wrapping machine, the operator can adjust the distance between the first plate 21 and the second plate 22 by adjusting the position of the push rod base 82 in the guiding groove 321 according to the thickness of the insulating paper 6, so as to adjust the size of the guiding groove 23 along the circumferential direction of the wire passing hole 12.

[0066] Optionally, during the adjustment of the size of the guiding groove 23 along the circumferential direction of the wire passing hole 12, only the position of the first plate 21 or only the position of the second plate 22 can be selected for adjustment. Of course, the positions of the first plate 21 and the second plate 22 can also be adjusted simultaneously, and all are within the protection scope.

[0067] As Figures 1 to 4 shown, the tensioning assembly 4 of the embodiment of the present application includes a first tensioning wheel 41 and a second tensioning wheel 42.

[0068] Among them, the first tensioning wheel 41 is rotatably installed on the mounting seat 1, and there are multiple first tensioning wheels 41, and the multiple first tensioning wheels 41 are not collinear. It can be understood that: the first tensioning wheels 41 are arranged in a staggered manner in the direction of the connection line between the guiding 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 spiral diversion lines with a depth of 0.3 mm - 1.0 mm. By setting the spiral diversion lines, the friction between the insulating paper 6 and the surface of the first tensioning wheel 41 can be reduced, and the wear of the insulating paper 6 and the first tensioning wheel 41 can be reduced.

[0069] In some embodiments, other patterns that can reduce the frictional force between the first tensioning wheel 41 and the surface of the insulating paper 6 may be provided on the surface of the first tensioning wheel 41, and all are within the protection scope.

[0070] In the paper wrapping machine disclosed in the embodiments of the present application, a pressure sensor for monitoring the pressure of the insulating paper 6 on the first tensioning wheel 41 is also provided to monitor the tension force of the insulating paper 6 on the first tensioning wheel 41.

[0071] The second tensioning wheel 42 is rotatably mounted on the driven wheel 32, that is, the second tensioning wheel 42 can rotate synchronously with the driven wheel 32, and the second tensioning wheel 42 can also rotate around its own axis. It can be understood that: the second tensioning wheel 42 can rotate on its own and can rotate around the axis of the driven wheel 32. Optionally, the number of the second tensioning wheels 42 can be one, and of course, it can also be multiple. The second tensioning wheel 42 and the guiding groove 23 are arranged along the radial direction of the driven wheel 32.

[0072] It should be noted that: the second tensioning wheel 42 rotates with the driven wheel 32, which can guide the insulating paper 6, ensure that the insulating paper 6 can be stably conveyed to the guiding groove 23, and can ensure the conveying direction of the insulating paper 6 to the guiding groove 23, and ensure the tension force of the insulating paper 6.

[0073] Optionally, the push rod 81 is a multi-link structure, and the push rod 81 includes a link extending radially from the driven wheel 32. By rotating the position of the link, the distance between the first plate 21 and the second plate 22 to the center of the circle can be adjusted, so as to change the adjustment of the distance between the guiding member 2 and the second tensioning wheel 42, and further change the tension force of the insulating paper 6, which is convenient for improving the bonding stability of the insulating paper 6 on the electromagnetic wire 7.

[0074] As Figures 1 to 3 shown, the wrapping paper storage assembly 5 includes: an infrared detection module 51, a box body 52, a reel 53, a drum 54 and a handle 55.

[0075] Among them, the box body 52 includes but is not limited to an openable closed structure to ensure the cleanliness of the insulating paper 6 inside the box body 52.

[0076] A reel 53 is arranged inside the box body 52, and a drum 54 is arranged on the reel 53. The drum 54 can be rotatably arranged relative to the box body 52. Optionally, the reel 53 can be rotatably arranged inside the box body 52, and the drum 54 is circumferentially fixed on the reel 53; or, the reel 53 is fixed inside the box body 52, and the drum 54 is rotatably sleeved on the reel 53.

[0077] The insulating paper 6 is wound around the drum 54, so that a material roll of the insulating paper 6 is formed on the drum 54.

[0078] The box body 52 is provided with a material outlet 521 at the position facing 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.

[0079] An infrared detection module 51 is provided at the material outlet 521 on the box body 52, and the infrared detection module 51 is used to detect whether there is insulating paper 6 at the material outlet 521. When the infrared detection module 51 detects that there is no insulating paper 6 passing through the material outlet 521, the infrared detection module 51 triggers the alarm device of the paper wrapping machine to remind the operator to end the paper wrapping operation. Optionally, the alarm device includes but is not limited to an audible and visual alarm device, and the alarm device is communicatively connected to the infrared detection module 51.

[0080] In some embodiments, the infrared detection module 51 can also be communicatively connected to the drive motor that drives the driving wheel 31 to rotate. When the infrared detection module 51 detects that there is no insulating paper 6 passing through the material outlet 521, the infrared detection module 51 triggers the alarm device and at the same time controls the drive motor to stop working.

[0081] Based on the above technical solution, the paper wrapping machine disclosed in the present application further includes a control panel (not shown in the figure). The above controller is integrated in the control panel, and the controller is communicatively connected to the drive motor of the drive assembly 3. The controller can control the rotation speed of the drive motor.

[0082] In some embodiments, the human-machine interface of the control panel presets multiple modes, including but not limited to: a normal mode and a high-speed mode.
