Description

Technical Field

[0001] This application relates to the field of winding technology, and in particular to a sheath winding device with rotation compensation feeding. Background Technology

[0002] In the technological development of sheath winding equipment, traditional equipment typically uses a fixed hopper combined with a mechanical transmission system to transport and wind the sheath tape. This type of equipment drives the cable or pipe in a circumferential motion via a rotating shaft, while a tension control device ensures the sheath tape is evenly wrapped around the substrate surface. It has been widely used in the processing of protective layers for power cables, communication optical cables, and oil pipelines. However, with increasing demands for winding precision and production efficiency in industrial settings, existing technologies have gradually revealed core defects such as accumulated torsional stress in the sheath tape and fluctuations in winding tightness. The root cause lies in the difference in motion direction between the fixed hopper and the rotating substrate. When the sheath tape is transported from the stationary hopper to the high-speed rotating substrate, the torque generated by the linear feeding and rotational winding motion modes cannot be effectively released, leading to irreversible deformation of the fibers inside the sheath tape. Furthermore, the passive tension adjustment system relied upon by traditional equipment struggles to match the torque changes during the dynamic winding process in real time. Especially under high-speed production conditions, the rigid connection characteristics of the mechanical structure further exacerbate the torque compensation lag problem, ultimately causing quality defects such as spiral deformation, localized loosening, or excessive stretching of the sheath layer. Utility Model Content

[0003] The purpose of this application is to overcome at least one deficiency of the prior art and provide a sheath winding device with rotation compensation feeding. The device, through the design of a self-spinning feeder, enables the sheath belt to rotate synchronously with the substrate during the conveying stage, fundamentally eliminating the torque accumulation caused by the difference in motion direction and improving the uniformity and mechanical properties of the sheath layer structure.

[0004] This application discloses a sheath winding device with rotational compensation feeding function, the overall structure of which includes a frame, a planetary gear winding mechanism, a drive assembly, a spin compensation feeding device and a controller.

[0005] The frame serves as a basic support platform, on which a main spindle roller supported by a double-row angular contact bearing is mounted. The outer surface of the main spindle roller is integrally formed with an annular transmission boss to form a power transmission interface.

[0006] The planetary gear winding mechanism includes a planetary sleeve and a fixed-axis sleeve eccentrically assembled inside the main shaft drum. The planetary sleeve and the fixed-axis sleeve have an eccentric distance from the axis of the main shaft drum. The rotational motion of the main shaft drum drives the planetary sleeve and the fixed-axis sleeve to generate relative planetary motion, thereby realizing the three-dimensional spatial trajectory winding of the sheath material.

[0007] The drive assembly drives the main shaft roller to rotate. The drive assembly consists of a motor and a synchronous belt that are controlled by the controller. The output end of the servo drive motor is equipped with an active synchronous pulley and is connected to the annular transmission boss through the synchronous belt for transmission.

[0008] The spin compensation feeding device is installed on the side of the frame and dynamically cooperates with one end of the planetary gear winding mechanism. The device includes a rotating feeding bin, a bin motor controlled by a controller, and a transmission belt. A driven synchronous pulley is provided at the bottom of the feeding bin. The transmission belt and the output wheel of the bin motor form a transmission chain, so that the feeding bin generates a compensation angular velocity that matches the movement of the main shaft roller during the winding process, effectively eliminating the torsional stress of the material.

[0009] As an optional technical solution, in order to optimize the winding path accuracy, the outer circumferential surface of the planetary sleeve is provided with an involute guide rail, and the mechanism adopts a variable curvature hard alloy guide rod structure.

[0010] As an optional technical solution, the spin-compensated feeding device also includes a guide bracket for guiding the material in order to guide the winding of the sheath.

[0011] As an optional technical solution, the controller is connected to a foot pedal, which serves as the terminal for starting and stopping the equipment.

[0012] As an optional technical solution, the frame is provided with a traction feeding device on the side opposite to the other end of the planetary gear winding mechanism. The traction feeding device includes parallel and symmetrical conveyor belts, wherein at least one conveyor belt is equipped with a control motor, which is used to realize automatic feeding control of the workpiece being wound through the synchronous movement of the two conveyor belts.

[0013] Compared with the prior art, this application achieves real-time matching between the conveying direction of the sheath belt and the rotation direction of the workpiece being wound by synchronous compensation rotation of the spin compensation feeding device and the planetary gear winding mechanism, thus completely eliminating the problem of torque accumulation caused by the difference in motion direction in traditional equipment, avoiding irreversible deformation of the fibers inside the sheath belt, and improving the winding effect.

[0023] See attached document Figures 1 to 3 This embodiment discloses an exemplary structure of a sheath winding device with rotational compensation feeding function, wherein the various components of the device cooperate with each other to achieve efficient sheath winding operation.

[0024] In this embodiment, the device mainly consists of a frame 1, a planetary gear winding mechanism 2, a drive assembly 3, a spin compensation feeding device 4, and a controller (not shown in the figure).

[0025] Among them, the frame 1 serves as the basic load-bearing platform for the entire equipment. It is made of high-strength steel, which has good stability and load-bearing capacity, and can provide a stable installation foundation for other components.

[0026] The main spindle roller 101 is supported on the frame by double-row angular contact bearings. This bearing configuration can effectively withstand forces and torques in various directions, ensuring the smooth rotation of the main spindle roller 101. An annular transmission boss 102 is integrally formed on the outer surface of the main spindle roller 101. This boss cooperates with the drive assembly 3 to form a reliable power transmission interface, ensuring efficient power transmission and thus realizing the rotation of the main spindle roller 101 around its axis.

[0027] In this embodiment, the drive assembly 3 is mainly responsible for driving the main shaft roller 101 to rotate. This assembly consists of a motor 301 controlled by a controller and a synchronous belt 302. The output end of the motor 301 is equipped with an active synchronous pulley, which is connected to the annular transmission boss 102 on the outer surface of the main shaft roller 101 via the synchronous belt 302, thereby achieving efficient power transmission. This transmission method has a simple structure and high transmission efficiency, ensuring the stable rotation of the main shaft roller 101, thus guaranteeing the continuity and stability of the winding operation.

[0028] Furthermore, in a preferred embodiment, the rotational speed of the motor 301 is controlled and adjusted by a controller. When winding sheath materials of different materials, the controller can precisely adjust the rotational speed of the motor 301 according to the process requirements, so that the winding speed matches the material characteristics and ensures the winding quality of the sheath material.

[0029] In this embodiment, the planetary gear winding mechanism 2 is one of the core components of the equipment, and the mechanism adopts a composite planetary gear set structure design.

[0030] Specifically, the planetary gear winding mechanism 2 includes a planetary sleeve 201 and a fixed-axis sleeve 202 eccentrically mounted inside the main shaft roller 101. The axes of the two sleeves form a preset eccentric distance with the axis of the main shaft roller 101 to achieve winding of the sheath material.

[0031] When the drive assembly 3 drives the main spindle roller 101 to rotate, relative planetary motion is generated between the planetary sleeve 201 and the fixed-axis sleeve 202 through the transmission principle of the planetary gear system, thereby realizing the complex trajectory winding of the sheath material in three-dimensional space. This winding method enables the sheath material to be wound evenly and tightly on the workpiece, improving the winding quality and efficiency.

[0032] For example, when sheathing a cable, the planetary gear winding mechanism 2 can ensure that the sheath material is wound on the cable surface without overlap or gaps.

[0033] In this embodiment, the spin-compensating feeding device 4 is installed on the side of the frame 1 and dynamically engages with one end of the star wheel winding mechanism 2. This device includes a rotating feeding bin 401, a bin motor 402 controlled by a controller, and a transmission belt. The feeding bin is made of a lightweight yet robust material and has a large storage capacity to meet the needs of long-term winding operations. A driven synchronous pulley is located at the bottom of the feeding bin, forming a transmission chain with the motor output pulley via the transmission belt. The bin motor 401 drives the transmission belt according to the controller's instructions, thereby generating a compensating angular velocity in the feeding bin 401 during the winding process that matches the movement of the main shaft roller 101. This compensating angular velocity effectively eliminates the torsional stress of the sheath material during the winding process, avoids irreversible deformation of the fibers inside the material, and improves the service life and winding quality of the sheath material. For example, when winding high-strength fiber sheaths, the spin-compensating feeding device 4 allows the sheath material to remain naturally stretched before winding, resulting in a wound sheath material without twisting or wrinkles. Compared to traditional feeding methods, the service life of the sheath material can be extended.

[0034] In addition, the spin-compensated feeding device 4 also includes a guide bracket 403 for guiding materials. The guide bracket 403 is made of stainless steel, which has good rigidity and corrosion resistance. Its structural design is reasonable and can be adjusted according to the width and thickness of the sheath material to ensure that the sheath material maintains a stable position and posture during the feeding process.

[0035] The guide bracket 403 effectively prevents the sheath material from shifting and twisting during the feeding process, improves the accuracy and reliability of the feeding, and helps to improve the winding quality.

[0036] In some implementation scenarios, to optimize the winding path accuracy, the outer circumferential surface of the fixed-axis sleeve 202 is provided with an involute guide rail 203. This guide rail is a variable curvature cemented carbide guide rod structure. The variable curvature cemented carbide guide rod has high strength, high hardness, and good wear resistance, and can maintain stable performance under high-speed rotation and complex stress conditions. When the sheath material is wound, the involute guide rail 203 can accurately guide the movement trajectory of the sheath, so that the sheath material is wound along the predetermined path, improving the accuracy and stability of the winding path.

[0037] In this embodiment, the controller is the control center of the entire device and is connected to the foot pedal. Operators can conveniently and quickly start and stop the device by using the foot pedal.

[0038] In this embodiment, the frame 1 is also provided with a traction feeding device 5 on its side, opposite to the other end of the planetary gear winding mechanism 2. This device includes parallel and symmetrical conveyor belts, with at least one conveyor belt equipped with a control motor. The motor is a variable frequency speed control motor, capable of automatically adjusting the rotational speed of the rollers according to the winding speed and workpiece size. Through the synchronous movement of the two conveyor belts, automatic feeding control of the workpiece being wound can be achieved. For example, when winding a sheath around a long pipe, the traction feeding device 5 can automatically adjust the pipe's feed speed according to the winding process requirements, ensuring that the winding speed of the pipe matches that of the sheath material, thus improving winding efficiency and quality. Compared to the traditional manual feeding method, the winding efficiency is significantly improved.

[0039] Through the coordinated operation of the aforementioned components, the sheath winding equipment in this embodiment achieves efficient, precise, and stable sheath winding operations. Compared with existing technologies, it achieves real-time matching between the sheath conveyor direction and the rotation direction of the workpiece being wound, completely eliminating the torque accumulation problem caused by differences in motion directions in traditional equipment, avoiding irreversible deformation of the fibers inside the sheath, and significantly improving the winding effect. In practical applications, this equipment is widely used for sheath winding in fields such as wires and cables, optical fibers and cables, and precision instruments, providing a strong guarantee for improving product quality and production efficiency.

Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims.
