Description

Technical Field

[0001] This utility model relates to the field of winding frame technology, and more specifically, to a winding frame for winding transformer coils. Background Technology

[0002] A winding frame is a mechanical device used to support and wind wires, cables, or fibers. It is usually made of metal, plastic, or composite materials. Its core structure includes rollers (winding shafts), side plates (baffles), and a base. Winding frames are widely used in the production of electronic components such as transformers, motors, and inductors, as well as in industries such as textiles and cable manufacturing. Depending on the application, they can be divided into manual, semi-automatic, and fully automatic types. Automatic winding frames can achieve precise wire arrangement and constant tension control, improving winding efficiency and consistency. Key performance indicators include load-bearing capacity, speed adaptability, and corrosion resistance. For special scenarios (such as high-frequency or high-temperature environments), heat-resistant and interference-resistant materials must be selected in the design.

[0003] A search revealed that CN218525448U discloses a coil winding frame that addresses the problem that "when the equipment is working, it generates a certain amount of heat. Relying on the airflow through the heat dissipation mesh to dissipate the heat is not efficient enough. If heat cannot be dissipated in time, excessive heat will damage the equipment." The device addresses this by using coils of different diameters to avoid the coil frame being too short, causing the coil to be squeezed onto the frame. When the motor or other equipment is working, the coil expands due to heat and is compressed, leading to coil damage. However, this device lacks a path guidance function during coil winding, which can easily cause the coil to concentrate in one place on the winding roller, resulting in uneven mass distribution. This generates centrifugal force during rotation, causing equipment vibration or shaking, thus affecting the stability of equipment operation. Therefore, improvements are needed.

Ultimately, this causes the threading ring to move horizontally left and right at a uniform speed, ensuring that the coil is evenly wound on the outer surface of the winding roller, avoiding the situation where the coil is concentrated in one place on the winding roller, resulting in uneven mass distribution and affecting the stability of the equipment operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5As shown, this utility model provides a winding frame for winding transformer coils, including a base plate 1. A rectangular block 2 is fixedly connected to the top of the base plate 1. A first motor 3 is fixedly connected to the front of the rectangular block 2. A threaded rod 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. The other end of the threaded rod 4 passes through the rectangular block 2 and extends into the interior of the rectangular block 2, and is threadedly sleeved with a moving block 5. The bottom of the moving block 5 is movably connected to the interior of the top of the base plate 1. A diagonal rod 6 is hinged to the left side of the moving block 5. A movable frame 7 is hinged to the other end of the diagonal rod 6. The outer surface of the frame 7 is movably connected to the inner top of the base plate 1. The inner cavity of the movable frame 7 is movably fitted with a telescopic plate 8. The top of the telescopic plate 8 is fixedly connected with a threading ring 9. The inner surface of the threading ring 9 is smooth. When the first motor 3 starts running, it will cause the threaded rod 4 to rotate and cause the moving block 5 to move horizontally back and forth under the limiting action of the base plate 1, thereby causing the inclined rod 6 to move. At this time, the inclined rod 6 squeezes and pushes the movable frame 7, causing the movable frame 7 to drive the telescopic plate 8 and the threading ring 9 to move horizontally left and right along the inner surface of the base plate 1.

[0022] The bottom plate 1 has a crossbar 10 fixedly installed in its inner cavity. The outer surface of the crossbar 10 is movably connected to the inner part of the bottom of the movable frame 7. Due to the limiting effect of the crossbar 10, the movable frame 7 can only move horizontally left and right, driving the telescopic plate 8 and the threading ring 9.

[0023] The bottom of the inner cavity of the movable frame 7 is fixedly connected to a fixing rod 11, and the outer surface of the fixing rod 11 is movably connected to the inside of the telescopic plate 8. The fixing rod 11 plays a role in limiting the movement of the threading ring 9, preventing it from detaching from the interior of the movable frame 7 when the telescopic plate 8 drives the threading ring 9 to move upward.

[0024] The base plate 1 has fixed plates 12 on both the left and right sides of the top. The right side of the fixed plate 12 is fixedly connected to the second motor 13. The other end of the output shaft of the second motor 13 is fixedly sleeved with a rotating shaft 14. The other end of the rotating shaft 14 passes through the fixed plate 12 and extends into the interior of the fixed plate 12, and is fixedly sleeved with a winding roller 15. When the second motor 13 starts running, the rotating shaft 14 will drive the winding roller 15 to rotate, and the winding operation of the coil will be performed.

[0025] The top of the fixed plate 12 is fixedly connected to the fixed frame 16, and the top of the fixed frame 16 is fixedly connected to the support base 17. The drive motor 18 is fixedly installed inside the support base 17. The other end of the output shaft of the drive motor 18 is fixedly sleeved with a rotating rod 19, and the other end of the rotating rod 19 is fixedly sleeved with a rotating rod 20. The outer surface of the rotating rod 20 is movably connected to a sleeve rod 21, and the bottom end of the sleeve rod 21 is fixedly connected to a vertical rod 22. When the drive motor 18 starts running, the rotating rod 19 will drive the rotating rod 20 to rotate, thereby causing the rotating rod 20 to squeeze and push the sleeve rod 21, causing the sleeve rod 21 to drive the vertical rod 22 to move downward.

[0026] The bottom end of the vertical rod 22 passes through the fixing frame 16 and extends into the interior of the fixing frame 16, and is fixedly connected to the connecting plate 23. Rectangular rods 24 are fixedly connected to the top left and right sides of the connecting plate 23. The top of the rectangular rods 24 passes through the fixing frame 16 and extends to the outside of the fixing frame 16. Due to the limiting effect of the rectangular rods 24 on the left and right sides, the connecting plate 23 is more stable during its downward movement.

[0027] The connecting plate 23 is internally fitted with a movable rod 25. The top of the movable rod 25 passes through the connecting plate 23 and the fixing frame 16 and extends to the outside of the fixing frame 16. The bottom end of the movable rod 25 is fixedly connected to an arc-shaped pressure plate 26. Springs 27 are fixedly connected to the four corners of the top of the arc-shaped pressure plate 26. The other end of the spring 27 is fixedly connected to the bottom end of the connecting plate 23. Due to the elastic force of the spring 27, the coil wound on the outer surface of the winding roller 15 can always be pressed tightly by the arc-shaped pressure plate 26, thereby ensuring that the coil will not become loose.

[0028] Working principle and usage process of this utility model:

[0029] First, one end of the coil is passed through the threading ring 9 and wound onto the winding roller 15. Then, the second motor 13 is started, which causes the rotating shaft 14 to drive the winding roller 15 to rotate. At this time, the winding operation of the transformer coil will be carried out. At the same time, the first motor 3 is started, which causes the threaded rod 4 to rotate and the moving block 5 to move horizontally back and forth under the limiting action of the base plate 1. This causes the inclined rod 6 to move. At this time, the inclined rod 6 squeezes and pushes the movable frame 7, which causes the movable frame 7 to drive the telescopic plate 8 and the threading ring 9 to move horizontally left and right along the inner surface of the base plate 1 under the limiting action of the crossbar 10. Finally, the threading ring 9 moves horizontally left and right at a uniform speed, and the coil is evenly wound on the outer surface of the winding roller 15, avoiding the situation where the coil is concentrated in one place on the winding roller, resulting in uneven mass distribution and affecting the stability of the equipment operation. When there is a lot of coil wound on the winding roller 15, which causes the radius of the winding roller 15 to increase, the coil will drive the threading ring 9 and the telescopic plate 8 to move vertically upward under the limiting action of the movable frame 7.

[0030] When the winding operation begins, the drive motor 18 is started simultaneously, causing the rotating rod 19 to drive the rotating rod 20 to rotate. The rotating rod 20 then presses against the push rod 21. At this time, the vertical rod 22 drives the connecting plate 23 and the arc-shaped pressure plate 26 to descend synchronously, eventually bringing the bottom of the arc-shaped pressure plate 26 into contact with the coil. As the number of coil turns on the winding roller 15 increases, the coil presses against the arc-shaped pressure plate 26, causing the arc-shaped pressure plate 26 to drive the movable rod 25 to move vertically upward under the limiting action of the connecting plate 23 and the fixed frame 16. At this time, the four springs 27 are compressed, ensuring that the arc-shaped pressure plate 26 remains firmly attached to the outer surface of the coil, thus preventing the coil from becoming loose and improving the quality of the coil winding operation.
