Description

Technical Field

[0001] This utility model relates to the field of coil bundling technology, and in particular to a coil bundling rotary guide device. Background Technology

[0002] In automated bundling and winding equipment for industrial coils (such as aluminum wire coils and copper wire coils), the rotating platform is the core component for achieving orderly winding of the wires. Traditional structures typically use a spindle and bearings to directly support the rotating table, which is driven by a motor through gears or chains.

[0003] However, under conditions of long-term, high-speed or heavy-load operation, the rotating system supported only by the main bearing is prone to problems such as radial runout, axial movement and rotational sway, which leads to a decrease in the coaxiality of the rotary table, and in turn causes uneven wire winding, interlayer misalignment and inconsistent tightness, which seriously affects the coil forming quality and subsequent performance.

[0004] A more prominent problem is that the radial guidance and support functions of the rotary table in existing equipment rely entirely on the main bearing. The bearing bears large radial and bending moment loads, which easily accelerates wear, leading to rapid decline in equipment accuracy, short maintenance cycles, and in severe cases, even equipment failure and downtime. In addition, if the transmission system lacks effective tensioning and protection, chain jumping and slackness are also prone to occur, affecting the smoothness and safety of operation. Utility Model Content

[0005] This utility model provides a coil bundling and rotating guide device, including a base. A guide plate is fixedly installed on the upper end of the base. Multiple sets of inclined guide wheels are evenly arranged in the inner circumference of the guide plate. A coil rotating mechanism is rotatably installed on the upper part of the base. The coil rotating mechanism passes through the guide plate and extends upward. Its lower part rolls in contact with the wheel surfaces of each guide wheel to achieve radial positioning and rotational support. The coil rotating mechanism is driven to rotate by a chain transmission mechanism and achieves orderly bundling of the wires under the guidance of the guide wheels.

[0006] Preferably, the lower surface of the guide plate is fixedly connected to the base by a plurality of radially distributed support bars, and the bottom end of each support bar is fixedly installed on the base to provide stable support for the guide plate.

[0007] Preferably, the inner contact surface of the guide wheel is provided with a V-groove, and the surface of the V-groove is provided with anti-slip knurling.

[0008] Preferably, the coil rotating mechanism includes a vertically arranged rotating column, the lower end of which is rotatably mounted on a support column fixed to the base via a bearing, the upper end of which passes through a guide plate and is fixedly connected to the rotating table, and the through-part of the rotating column and the guide plate is rotatably connected via a bearing.

[0009] Preferably, the upper surface of the rotary table has three sets of interconnected binding grooves for accommodating binding tape during the binding process, which facilitates the tight binding of the coil.

[0010] Preferably, a plurality of guardrails are arranged in a ring on the outer peripheral sidewall of the rotary table, and the guardrails are spaced apart along the circumference to limit the axial displacement of the coil placed on the rotary table during rotation.

[0011] Preferably, the outer periphery of the support column is provided with several reinforcing ribs, one end of each reinforcing rib is connected to the support column and the other end is connected to the base, which is used to enhance the structural rigidity and bending resistance of the support column.

[0012] Preferably, the chain drive mechanism includes a second sprocket fixedly sleeved on the outside of the rotating column, a drive motor installed at one end of the base, the output shaft of the drive motor connected to the rotating shaft of the first sprocket, and a drive chain sleeved between the first sprocket and the second sprocket to transmit the power of the drive motor to the rotating column, thereby driving the rotating table to rotate.

[0013] Preferably, a support platform is fixedly provided on the base, and an outer sprocket and an inner sprocket are symmetrically installed on the support platform. The outer sprocket meshes with the outer side of the transmission chain, and the inner sprocket meshes with the inner side of the transmission chain, for tensioning and guiding the transmission chain.

[0014] Preferably, one end of the base is provided with a protective cover, which covers the outside of the sprocket and the drive chain.

[0015] This utility model provides a coil bundling rotary guide device, which, compared with the prior art, has the following advantages: 1. This utility model sets multiple sets of inclined guide wheels on the guide plate, and the inner wheel surface of the guide wheels rolls in contact with the outer wall of the rotating column to form a circumferential envelope support for the rotating column. This achieves precise guidance and radial positioning of the rotating table during rotation. This structure effectively distributes the radial load of the main bearing, improves the operational stability of the rotating system, and suppresses possible swaying, vibration or axial movement during high-speed rotation. It ensures that the rotating table maintains good coaxiality and operational accuracy during long-term continuous operation, thus providing a reliable motion basis for the uniform bundling of coils.

[0016] 2. The guide wheel of this utility model adopts a V-groove structure and is combined with an anti-slip knurled design, which forms a stable rolling contact interface with the surface of the rotating column. This increases friction, prevents relative slippage, avoids rigid jamming, and ensures smooth transmission. The V-groove can automatically correct deviation, and even with minor installation errors or running wear, it can still maintain a good guiding effect. Combined with auxiliary structures such as support bars, reinforcing ribs, and chain tensioning structures, the overall device has high strength, high rigidity, and high reliability. It not only extends the service life of key components, but also improves the safety and ease of maintenance of the equipment. It is particularly suitable for high-load, high-precision industrial coil automatic bundling operations. Attached Figure Description

Detailed Implementation

[0020] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] Please refer to Figures 1-7 This utility model provides a coil bundling rotary guide device, including a base 10, which serves as the mounting base for the entire device. A ring-shaped guide disk 18 is fixedly mounted on the upper end of the base 10. Multiple sets of inclined guide wheels 19 are evenly arranged circumferentially inside the guide disk 18. Each guide wheel 19 is rotatably mounted on the wheel seat of the guide disk 18 through bearings. Its axis forms a certain angle with the axis of the rotating column 20 to optimize the force distribution.

[0022] refer to Figure 5 The lower surface of the guide plate 18 is fixedly connected to the base 10 by a number of radially distributed support bars 17. The two ends of the support bars 17 are fixed to the guide plate 18 and the base 10 by bolts or welding, respectively, providing stable radial and axial support for the guide plate 18.

[0023] refer to Figure 7 The inner contact surface of the guide wheel 19 is provided with a V-shaped groove, and the surface of the groove wall is machined with anti-slip knurling 28, which is used to form a stable rolling contact with the outer wall of the rotating column 20 of the coil rotating mechanism, improve friction, prevent slippage, and have a certain automatic correction capability.

[0024] The coil rotation mechanism includes a vertically arranged rotating column 20. The lower end of the rotating column 20 is rotatably mounted on a support column 15 fixed to the base 10 via a bearing. Several reinforcing ribs 16 are provided on the outer periphery of the support column 15. One end of each reinforcing rib 16 is connected to the support column 15, and the other end is connected to the base 10 to enhance the rigidity and bending resistance of the overall structure.

[0025] The upper end of the rotating column 20 passes through the guide plate 18 and is fixedly connected to the rotating platform 25 above. The part through which the rotating column 20 and the guide plate 18 pass is rotatably connected by a bearing to ensure that there is no frictional interference between the rotating column 20 and the guide plate 18 during rotation.

[0026] refer to Figure 6 The rotating table 25 is used to support the coils to be bundled. Its upper surface has three sets of interconnected bundling slots 26, which facilitate the insertion of bundling tape or steel tape for fastening after bundling.

[0027] Several guardrails 27 are distributed in a ring on the outer peripheral sidewall of the rotary table 25. Each guardrail 27 is spaced apart along the circumference to limit the axial displacement of the coil during rotation and prevent it from shifting or falling off under the action of centrifugal force.

[0028] The power transmission is achieved by a chain drive mechanism, which includes a second sprocket 21 fixedly sleeved on the outside of the rotating column 20, a drive motor 13 installed at one end of the base 10, the output shaft of the drive motor 13 being connected to the rotating shaft of the first sprocket 14, and a transmission chain 22 sleeved between the first sprocket 14 and the second sprocket 21, used to transmit the power of the drive motor 13 to the rotating column 20, thereby driving the rotating table 25 to rotate.

[0029] To ensure the smooth operation of the transmission chain 22, a support platform 12 is fixedly installed on the base 10, and an outer sprocket 23 and an inner sprocket 24 are symmetrically installed on the support platform 12.

[0030] like Figure 4 As shown, the outer sprocket 23 meshes with the outer side of the transmission chain 22, and the inner sprocket 24 meshes with the inner side of the transmission chain 22. Together, they tension and guide the transmission chain 22 to prevent it from jumping or loosening during operation.

[0031] In addition, a protective cover 11 is provided at one end of the base 10. The protective cover 11 covers the outside of the first sprocket 14, the transmission chain 22 and part of the second sprocket 21 to prevent dust and oil from entering the transmission system, and at the same time avoids the operator from contacting the moving parts, thereby improving the safety of the equipment.

[0032] In summary, during operation, the drive motor 13 starts and drives the sprocket 21 to rotate through the sprocket 14 and the transmission chain 22, thereby driving the rotating column 20 and its fixed rotating table 25 to rotate synchronously. During this process, the outer wall of the rotating column 20 maintains rolling contact with the multiple inclined guide wheels 19 on the guide plate 18. The V-groove and anti-slip knurling structure of the guide wheel 19 effectively provide radial guidance and support, share the load of the main bearing, suppress rotational sway and vibration, and ensure that the rotating table 25 runs smoothly. The coil is placed on the rotating table 25 and limited by the guardrail 27. After bundling, the binding strap passes through the binding groove 26 for fastening.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
