Description

Technical Field

[0001] This utility model belongs to the field of foil winding machine technology, and specifically relates to a foil winding machine. Background Technology

[0002] A foil winding machine, also known as a foil coil winding machine or foil winding machine, is a specialized piece of equipment for winding foil coils for transformers.

[0003] CN221040823U discloses a foil winding machine for transformer production, comprising a base, a placement frame fixedly mounted on the top of the base, an installation groove formed at the top of the placement frame, a rotating column movably mounted inside the installation groove, limit blocks fixedly mounted at both ends of the rotating column, a metal foil ring fixedly mounted on the surface of the rotating column, a pressing mechanism, a winding mechanism, and a guiding mechanism on the top of the base. The guiding mechanism includes a guide frame fixedly mounted on the top of the base, which, through a movable rod, allows the metal foil to pass between roller B and roller A. Roller B, driven by a compression spring A pressing against roller bearing B, moves, causing roller B and roller A to compress the metal foil, thereby ensuring the flatness of the metal foil, achieving the guiding function of the metal foil, and preventing interference with continuous winding.

[0004] The foil winding machine provided by the aforementioned patent has a limited practicality because the size of the mounting frame is not adjustable due to its integrated design. Therefore, it cannot clamp and fix foil coils of different sizes. Furthermore, the fixed size of the mounting frame prevents it from stably clamping the foil coils, resulting in poor device usability.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a foil winding machine that can solve the problems of the mounting frame being unable to fix foil coils of different sizes and the poor stability of the mounting frame when clamping foil coils.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A foil winding machine, comprising:

[0009] A foil ring mounting assembly includes an operating table on which a pair of first mounting plates are fixedly connected. A metal foil ring is rotatably connected between the pair of first mounting plates in a detachable manner, so that the metal foil ring can be easily installed between the pair of first mounting plates for easy replacement during use.

[0010] The foil winding assembly includes a pair of second mounting plates, which are fixedly connected to an operating table. Mounting plates are mounted on opposite side walls of the pair of second mounting plates. Mounting blocks are mounted on the side walls of the mounting plates away from the second mounting plates. Each mounting block has a groove, and a pair of sliders are slidably connected within the groove, allowing the sliders to slide within the groove. Clamping plates are fixedly connected to the outer ends of each pair of sliders within the groove, allowing the sliders to slide along the clamping plates, thus adjusting the distance between the clamping plates. Since the clamping plates are used to clamp and fix the foil coil, the adjustable distance between the clamping plates allows for clamping and fixing foil coils of different inner diameters. A bidirectional screw is rotatably connected inside the groove. A pair of sliders are respectively threaded onto the positive and negative threads of the bidirectional screw, so that the sliding of the sliders is achieved by the rotation of the bidirectional screw. When the bidirectional screw rotates, it can drive a pair of clamping plates to move closer to or further away from each other. When the bidirectional screw stops rotating, it can drive the distance between the pair of clamping plates to be constant. Therefore, the rotation of the bidirectional screw enables the pair of clamping plates to clamp foil coils of different sizes while maintaining stable clamping of the foil coils.

[0011] In one or more embodiments of the present invention, a first rotating shaft is rotatably connected through one of the first mounting plates, and a first adjusting screw is threaded through another of the first mounting plates.

[0012] In one or more embodiments of this utility model, a socket frame is installed at the opposite end of both the first rotating shaft and the first adjusting screw. The socket frame on the first rotating shaft is installed in a fixed connection manner, so that the first rotating shaft and the socket frame are fixed together. The socket frame on the first adjusting screw is installed in a rotatable manner, so that the first adjusting screw and the socket frame can rotate. At the same time, since the first adjusting screw can move by rotating on the first mounting plate, the movement of the first adjusting screw can drive the connected socket frame to move.

[0013] In one or more embodiments of this utility model, both the front and rear ends of the metal foil ring are fixedly connected to a sleeve shaft, and limit holes are provided on both the sleeve shaft and the side walls of the sleeve frame.

[0014] In one or more embodiments of this utility model, the sleeve shaft is sleeved inside the sleeve frame, and fixing bolts are installed on the sleeve shaft and the sleeve frame through limiting holes. The fixing bolts can fix the sleeve shafts at both ends of the metal foil ring inside the sleeve frame, so that the metal foil ring can be rotated when the sleeve frame rotates. At the same time, since the sleeve shaft and the sleeve frame are fixed through the limiting holes, the easy disassembly and assembly of the limiting holes makes it convenient to replace the metal foil ring.

[0015] In one or more embodiments of the present invention, a second rotating shaft is rotatably connected through one of the second mounting plates, and a second adjusting screw is threaded through another of the second mounting plates.

[0016] In one or more embodiments of this utility model, one end of each pair of mounting plates is fixedly connected to the opposite end of a second rotating shaft and a second adjusting screw. A motor is mounted on the end of the second rotating shaft away from the mounting plates. The motor drives the second rotating shaft to rotate, thereby causing the connected mounting plates to rotate.

[0017] In one or more embodiments of this utility model, a fixed connector is provided between the mounting plate connected to the second rotating shaft and the corresponding mounting block, thereby fixing the mounting plate and the mounting block connected to the second rotating shaft together. A rotating connector is provided between the mounting plate connected to the second adjusting screw and the corresponding mounting block, thereby connecting the mounting plate and the mounting block connected to the second adjusting screw together in a rotatable manner, allowing the mounting block connected to the second adjusting screw to rotate.

[0018] In one or more embodiments of this utility model, a rotating block is fixedly connected to one end of the bidirectional screw located outside the mounting block. The rotating block drives the bidirectional screw to rotate, thereby facilitating the adjustment of the distance between a pair of clamping plates. The clamping plates abut against the inner wall of the foil coil, allowing the clamping plates to clamp and fix the inner wall of the foil coil.

[0019] In one or more embodiments of this utility model, the side of the clamping plate that contacts the inner wall of the foil coil is configured as an arc-shaped surface, so that the side of the clamping plate that contacts the foil coil can adhere to the inner wall of the foil coil. An anti-slip layer is provided on the arc-shaped surface, which increases the friction between the clamping plate and the foil coil, ensuring the stable fixation of the clamping plate to the foil coil.

[0020] Compared with the prior art, this utility model sets up a pair of clamping plates with an adjustable spacing. When clamping the foil coil, the spacing of the clamping plates can be adjusted by rotating the bidirectional screw, so that the clamping plates can clamp and fix foil coils of different sizes. At the same time, the adjustment of the spacing makes the clamping plates more stable in fixing the foil coil, thus improving practicality. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-3 As shown, a foil winding machine according to one embodiment of the present invention includes a foil ring mounting assembly 1 and a foil ring winding assembly 2.

[0031] like Figures 1-3 As shown, the foil ring mounting assembly 1 includes an operating table 11, on which a pair of first mounting plates 12 are fixedly connected. A metal foil ring 13 is rotatably connected between the pair of first mounting plates 12 in a detachable manner, so that the metal foil ring 13 can be easily installed between the pair of first mounting plates 12 for easy replacement during use.

[0032] like Figures 1-3 As shown, a first rotating shaft 16 is rotatably connected to any one of the first mounting plates 12 in a through manner, and a first adjusting screw 17 is threadedly connected to the other first mounting plate 12 in a through manner.

[0033] like Figures 1-4 As shown, a socket frame 18 is installed at one end of both the first rotating shaft 16 and the first adjusting screw 17. The socket frame 18 on the first rotating shaft 16 is installed in a fixed connection manner, so that the first rotating shaft 16 and the socket frame 18 are fixed together. The socket frame 18 on the first adjusting screw 17 is installed in a rotatable manner, so that the first adjusting screw 17 and the socket frame 18 can rotate together. At the same time, since the first adjusting screw 17 can move on the first mounting plate 12 by rotation, the movement of the first adjusting screw 17 can drive the connected socket frame 18 to move.

[0034] Preferably, the spacing between a pair of socket frames 18 can be adjusted by rotating the first adjusting screw 17, thereby enabling the installation and fixing of metal foil rings 13 of different widths, which improves the practicality of the device.

[0035] like Figure 2 and Figure 4 As shown, both the front and rear ends of the metal foil ring 13 are fixedly connected to the sleeve shaft 14, and limit holes 15 are opened on both sides of the sleeve shaft 14 and the sleeve frame 18.

[0036] like Figure 2 and Figure 4As shown, the sleeve shaft 14 is sleeved inside the sleeve frame 18. Fixing bolts 19 are installed on the sleeve shaft 14 and the sleeve frame 18 through the limiting holes 15. The fixing bolts 19 can fix the sleeve shaft 14 at both ends of the metal foil ring 13 inside the sleeve frame 18, so that when the sleeve frame 18 rotates, it can drive the metal foil ring 13 to rotate. At the same time, since the sleeve shaft 14 and the sleeve frame 18 are fixed through the limiting holes 15, the easy disassembly and assembly of the limiting holes 15 makes it convenient to replace the metal foil ring 13.

[0037] like Figures 1-3 and Figure 5 As shown, the foil winding assembly 2 includes a pair of second mounting plates 21, which are fixedly connected to the operating table 11. Mounting plates 24 are mounted on opposite side walls of the pair of second mounting plates 21. Mounting blocks 25 are mounted on the side walls of the mounting plates 24 away from the second mounting plates 21. A groove 26 is formed within the mounting block 25, and a pair of sliders 27 are slidably connected within the groove 26, allowing the sliders 27 to slide within the groove 26. A clamping plate 28 is fixedly connected to one end of each slider 27 located outside the groove 26, allowing the sliders 27 to slide within the groove 26, thus adjusting the distance between the clamping plates 28. Since the clamping plates 28 are used to clamp and fix the foil coil 213, the adjustable distance between the clamping plates 28 allows for the clamping and fixing of foil coils 213 with different inner diameters. A bidirectional screw 210 is rotatably connected inside the slide groove 26. A pair of sliders 27 are respectively threaded onto the positive and negative threads of the bidirectional screw 210, so that the sliding of the sliders 27 is achieved by the rotation of the bidirectional screw 210. Thus, when the bidirectional screw 210 rotates, it can drive a pair of clamping plates 28 to move closer to or further away from each other. When the bidirectional screw 210 stops rotating, the distance between the pair of clamping plates 28 is kept constant. Therefore, the rotation of the bidirectional screw 210 allows the pair of clamping plates 28 to clamp foil coils 213 of different sizes while keeping the clamping of the foil coils 213 stable.

[0038] like Figures 1-3 As shown, a second rotating shaft 22 is rotatably connected to any one of the second mounting plates 21 in a through manner, and a second adjusting screw 23 is threadedly connected to the other second mounting plate 21 in a through manner.

[0039] like Figures 1-3 As shown, one end of a pair of mounting plates 24 is fixedly connected to the opposite end of the second rotating shaft 22 and the second adjusting screw 23, respectively. A motor is mounted on the end of the second rotating shaft 22 away from the mounting plates 24. The motor drives the second rotating shaft 22 to rotate, so that the second rotating shaft 22 drives the connected mounting plates 24 to rotate.

[0040] like Figure 3 and Figure 5 As shown, a fixed connector 211 is provided between the mounting plate 24 connected to the second rotating shaft 22 and the corresponding mounting block 25, thereby fixing the mounting plate 24 and the mounting block 25 connected to the second rotating shaft 22 together. A rotating connector 212 is provided between the mounting plate 24 connected to the second adjusting screw 23 and the corresponding mounting block 25, thereby connecting the mounting plate 24 and the mounting block 25 connected to the second adjusting screw 23 together in a rotatable manner, allowing the mounting block 25 connected to the second adjusting screw 23 to rotate.

[0041] Preferably, the distance between the pair of mounting blocks 25 can be adjusted by rotating the second adjusting screw 23, so that the clamping plate 28 can clamp and fix foil coils 213 of different widths, thereby improving the practicality of the device.

[0042] like Figure 5 As shown, a rotating block is fixedly connected to one end of the bidirectional screw 210 located outside the mounting block 25. The rotating block drives the bidirectional screw 210 to rotate, so as to adjust the distance between the pair of clamping plates 28. The clamping plates 28 abut against the inner wall of the foil coil 213, so that the clamping plates 28 can clamp and fix the inner wall of the foil coil 213.

[0043] like Figure 5 As shown, the side of the clamping plate 28 that contacts the inner wall of the foil coil 213 is designed as an arc-shaped surface, so that the side of the clamping plate 28 that contacts the foil coil 213 can adhere to the inner wall of the foil coil 213. An anti-slip layer 29 is provided on the arc-shaped surface, which increases the friction between the clamping plate 28 and the foil coil 213, ensuring that the clamping plate 28 can stably fix the foil coil 213.

[0044] In use, the spacing between a pair of socket frames 18 is adjusted by rotating the first adjusting screw 17 to match the width of the metal foil ring 13. Then, the socket shafts 14 at both ends of the metal foil ring 13 are respectively fitted into the pair of socket frames 18, and the socket shafts 14 and socket frames 18 are fixed together by fixing bolts 19. The spacing between a pair of mounting blocks 25 is adjusted by rotating the second adjusting screw 23 to match the foil coil 213. The spacing between a pair of clamping plates 28 is adjusted by rotating the bidirectional screw 210 to be smaller than the inner diameter of the foil coil 213, so that the two ends of the foil coil 213 can be fitted onto the corresponding clamping plates 28. Then, by rotating the bidirectional screw 210, the pair of clamping plates 28 are tightly attached to the inner wall of the foil coil 213, so that the foil coil 213 is stably fixed by the clamping plates 28 at both ends of the foil coil 213. After the metal foil on the metal foil ring 13 is pulled out and wound around the foil coil 213 through the corresponding components, the metal foil can be wound by the drive of the motor.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
