Description

Technical Field

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

[0002] Existing sheathing winding equipment is widely used in cable manufacturing, pipeline protection, and other fields. Its basic principle is to form a protective layer by winding a strip of sheath around the surface of an object, thereby improving the durability and damage resistance of the protected object. However, in practical applications, existing sheathing winding equipment still has some technical shortcomings, especially in terms of the stress on the sheath strip and the winding precision.

[0003] Traditional sheathing wrapping equipment typically relies on rotation to wind the sheath tape onto the object being protected. However, due to the inherent strength and toughness of the sheath tape, it is subjected to significant torque during the winding process. Because current equipment designs lack effective torque compensation mechanisms, the sheath tape is prone to twisting during winding, especially during prolonged use or high-intensity winding. This twisting gradually intensifies and may even lead to irreversible deformation. Furthermore, the twisted sheath tape cannot maintain its tightness after winding, significantly impacting the wrapping effect and consequently affecting the protective efficacy and lifespan of the sheath tape.

[0004] These shortcomings mainly stem from the failure of existing technologies to effectively address the torsional force experienced by the sheath tape during winding. Because the sheath tape storage and conveying systems do not adequately consider mechanical properties, uneven stress occurs on the sheath tape during winding, leading to torsion and deformation. Although some equipment attempts to reduce torsion by adjusting the transmission method, these improvements have not fundamentally solved the problem and remain ineffective in suppressing the deformation and twisting of the sheath tape.

[0005] Therefore, it is particularly important to develop an automatic sheath winding device that can solve the problem of sheath belt torsion under stress in existing technologies. Utility Model Content

[0006] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a sheath winding device with rotational compensation that can effectively compensate for the torque experienced by the sheath tape during the winding process. This device places the sheath tape in a self-spinning hopper, and the rotational motion effectively compensates for the torque experienced by the sheath tape during the winding process, thereby improving problems such as sheath tape twisting and uneven density in traditional winding equipment.

[0007] To achieve the above objectives, this application discloses a sheath winding device with rotational compensation, which includes a frame, a main roller assembly horizontally mounted in the frame, and a power drive unit for driving the main roller to rotate around a horizontal axis.

[0008] The main roller assembly includes an axially penetrating hollow roller body and a concentric mounting plate coaxially fixedly connected thereto. The hollow roller body is provided with a hollow material guide pipe fixed to the frame and axially penetrating, which forms a material inlet channel.

[0009] The concentric mounting disc rotates synchronously with the main body of the roller. Two independently rotatable winding discs are symmetrically arranged on the center of the disc surface. The rotation direction of the winding discs is opposite to that of the concentric mounting discs through a transmission mechanism, thereby achieving dynamic rotation compensation.

[0010] It should be noted that the purpose of the centrally symmetrical arrangement is to facilitate the storage of two materials, and also to ensure that the rotational counterweight of the concentric mounting discs is balanced.

[0011] The winding tray includes a cylindrical storage bin, which is mounted on an eccentric position on the concentric mounting plate via bearings. A driven gear is fixed at its bottom. The hollow roller has a corresponding drive gear that meshes with the driven gear. The drive gear is linked to the rotation of the roller body via a chain, so that when the concentric mounting plate rotates with the roller body, the chain drives the driven gear to rotate the storage bin synchronously in the opposite direction, forming a reverse transmission compensation mechanism.

[0012] Furthermore, the inner wall of the hollow material guide tube is fitted with an ultra-high molecular weight polyethylene wear-resistant bushing, and the inner surface of the bushing is provided with a spiral guide groove to optimize the axial conveying path of the tubular material.

[0013] Furthermore, the frame is equipped with a material guiding mechanism at the feeding end of the material inlet channel. This mechanism consists of multiple circumferentially distributed guide wheels. Each guide wheel is installed inside the frame via a radially adjustable bracket, forming a material guiding channel concentric with the axis of the material guiding pipe.

[0014] Furthermore, the material inlet channel is provided with a guide rod at the outlet end for guiding the sheath to feed and wind.

[0015] Furthermore, a traction assembly is positioned opposite the discharge end of the material inlet channel. This traction assembly comprises two sets of parallel rollers or horizontally parallel conveyor belts, wherein the roller sets or conveyor belts are mounted on a vertical lifting support to form a height-adjustable tube output channel. When roller sets are used, the roller surfaces are machined with arc-shaped guide grooves, and the vertical spacing between the two sets of rollers is adjusted via a ball screw mechanism driven by a servo motor. When a conveyor belt is used, the conveyor belt is made of wear-resistant rubber material, has guide flanges on both sides, and achieves traction speed matching through a synchronous belt pulley drive system in conjunction with a tension adjustment device.

[0016] Furthermore, the inner side of the frame is provided with a braking unit, which includes an arc-shaped friction block that matches the outer circumferential surface of the concentric mounting plate. The friction block is connected to the frame through a linear cylinder. When the equipment needs to brake, the linear cylinder pushes the friction block to contact the outer circumferential surface of the concentric mounting plate to generate frictional resistance.

[0017] Furthermore, the material guiding mechanism is paired with a tube material tray, which is horizontally rotatably mounted on a fixed frame. During operation, the driven self-rotation of the tube material tray counteracts or reduces the radial force on the tube when it is wound with the sheath, thereby improving the winding quality.

[0018] Compared with existing technologies, this application significantly improves the uniformity of sheath material winding and interlayer adhesion on the surface of tubular materials through the effective coordination of the reverse transmission compensation mechanism. The dynamic reverse rotation compensation design effectively counteracts the torque deviation generated during equipment operation, avoids loosening or displacement of the sheath material due to rotational inertia, and ensures that the material is always under stable stress during the winding process.

[0027] See attached document Figure 1 and 2 This embodiment discloses a sheath winding device with rotation compensation, which mainly consists of a frame 1, a main roller assembly 2, a power drive unit 3, a winding material tray 4, a guide pipe 5, a guide mechanism 6, a traction assembly 7, and a braking unit 8.

[0028] The frame 1, serving as the supporting foundation for the entire equipment, is welded from high-strength steel to ensure the stability and load-bearing capacity of the equipment during operation. The main roller assembly 2 is horizontally installed within the frame 1, comprising an axially continuous hollow roller body and a concentric mounting plate coaxially fixed to it. The hollow roller body is made of high-quality carbon steel, and its surface undergoes fine machining to ensure its cylindricity and smoothness, reducing friction with the material.

[0029] The concentric mounting disc rotates synchronously with the roller body, and two independently rotatable winding discs 4 are symmetrically mounted at the center of its disc surface. During operation, one winding disc 4 is used selectively, while the other serves as a symmetrical counterweight when idle.

[0030] The winding tray 4 includes a cylindrical storage bin, which is mounted on a concentric mounting plate via bearings. A driven gear is fixed at the bottom. A corresponding drive gear, meshing with the driven gear, is located on the hollow roller body. The drive gear is linked to the rotation of the roller body via a chain. When the concentric mounting plate rotates with the roller body, the chain drives the driven gear to rotate the storage bin synchronously in the opposite direction, forming a reverse transmission compensation mechanism. This effectively counteracts the torque deviation generated during equipment operation and prevents the sheathing material from loosening or shifting due to rotational inertia.

[0031] The power drive unit 3 is mounted on the frame 1 and is used to drive the main roller assembly 2 to rotate around a horizontal axis. This unit typically uses a servo motor and a reducer, connected to the main roller assembly 2 via a coupling, enabling precise speed control and stable power output, ensuring that the linear velocity of the material during the winding process matches the rotational speed of the main roller assembly 2. It should be noted that the specific selection and installation method of the servo motor and reducer are well-known techniques to those skilled in the art and will not be elaborated upon here.

[0032] The guide tube 5 is fixed to the frame 1 and axially penetrates the hollow drum body. Its inner wall is fitted with an ultra-high molecular weight polyethylene wear-resistant bushing, and the inner surface of the bushing has spiral guide grooves to optimize the axial conveying path of the tubular material. This design not only improves the wear resistance and self-lubricating properties of the guide tube 5, extending its service life, but also makes the material conveying process smoother, reducing resistance and friction loss. The frame 1 has a guiding mechanism 6 at the feed end of the material inlet channel. This mechanism consists of multiple circumferentially distributed guide wheels. Each guide wheel is mounted inside the frame 1 via a radially adjustable bracket, forming a guiding channel concentric with the axis of the guide tube 5. The guide wheels are made of nylon, which has good wear resistance and impact resistance, effectively guiding the material into the guide tube 5. It should be noted that the specific material selection of the guide wheels and the adjustment method of the radially adjustable bracket are within the scope of existing technology and are only briefly described here.

[0033] Furthermore, in this embodiment, the material inlet channel is equipped with a guide rod 9 at its outlet end for guiding the sheath material into the winding area. The guide rod 9 is a slender metal rod, typically made of steel or iron, possessing high strength and rigidity, capable of stably guiding the sheath material. One end is positioned at the outlet, and the other end extends close to the winding reel 4. After the sheath from the winding reel 4 is extended, it is guided by the guide rod 9 to smoothly reach the outlet position for sheath winding of the pipe fitting. The guide rod 9's design is simple and practical, effectively ensuring the stability of the sheath material during transport and preventing it from shifting or becoming disordered upon entering the winding area, thereby improving the accuracy and quality of the sheath winding.

[0034] Based on the above structure, it is important to understand that the main purpose of setting up two winding trays 4 in this embodiment is to achieve rotary counterweight and continuous production. Specifically, the two winding trays 4 are symmetrically installed on a concentric mounting plate, and both can hold sheathing material. During equipment operation, one winding tray 4 is typically used selectively for sheathing operations, while the other winding tray 4 serves as a symmetrical counterweight when idle. When the sheathing material on one winding tray 4 is used up, the other winding tray 4 can be switched to continue the winding operation, thereby achieving continuous production, reducing downtime for material changes, and improving production efficiency.

[0035] To achieve this selective switching, in some implementations, the guide rod 9 is designed to be rotatable. By rotating the guide rod 9, it can be aligned with the currently used winding reel 4, thereby accurately guiding the sheathing material to the outlet position for sheathing the pipe fitting. This rotatable guide rod 9 design not only improves the flexibility of the equipment but also ensures that the guide path of the sheathing material can be quickly and accurately adjusted when switching winding reels 4, avoiding material deviation or confusion during conveying, and further improving the accuracy and quality of sheathing winding.

[0036] This design has significant value in practical applications. On one hand, the symmetrical counterweights of the two winding reels 4 effectively counteract the torsional deviations generated during equipment operation, reducing the loosening or displacement of the sheath material caused by rotational inertia, thereby improving the uniformity of sheath material winding on the surface of tubular materials and the interlayer adhesion. On the other hand, the cooperative use of the rotatable guide rod 9 and the two winding reels 4 enables continuous production, reduces production costs, and improves production efficiency, making it particularly suitable for applications in industries such as wire and cable manufacturing where high precision and efficiency in sheath winding are required.

[0037] Continuing with the description of this embodiment, in this embodiment, the traction component 7 is positioned opposite the discharge end of the material inlet channel, and includes two sets of parallel roller groups or a horizontally parallel conveyor belt. When roller groups are used, the roller surfaces are machined with arc-shaped guide grooves, and the vertical spacing between the two sets of rollers is adjusted by a ball screw mechanism driven by a servo motor. When a conveyor belt is used, the conveyor belt is made of wear-resistant rubber material, with guide flanges on both sides, and the traction speed is matched by a synchronous belt pulley drive system in conjunction with a tension adjustment device. This design allows for flexible adjustment of the traction method and speed according to the characteristics of the material and the winding requirements, ensuring that the material maintains stable tension and conveying speed during the winding process, thereby improving the winding quality. It should be noted that the specific implementation methods of the servo motor-driven ball screw mechanism and the synchronous belt pulley drive system are well-known technologies to those skilled in the art and will not be disclosed in detail here.

[0038] The braking unit 8 is located inside the frame 1 and includes an arc-shaped friction block that matches the outer circumferential surface of the concentric mounting plate. The friction block is connected to the frame 1 via a linear cylinder. When braking is required, the linear cylinder pushes the friction block to contact the outer circumferential surface of the concentric mounting plate, generating frictional resistance and achieving a fast and smooth braking effect. The arc-shaped friction block is made of high-performance friction material, possessing excellent wear resistance and braking performance. It effectively controls the rotational speed of the equipment, preventing uneven material entanglement or damage due to inertia. It should be noted that the specific model selection and installation method of the linear cylinder fall within the scope of existing technology and are only briefly described here.

[0039] In actual operation, the tubular material is first guided into the central hollow guide tube 5 by the guiding mechanism 6, and then smoothly conveyed to the position of the main roller assembly 2 along the spiral guide groove. The power drive unit 3 drives the main roller assembly 2 to rotate, causing the concentric mounting plate to rotate synchronously. At this time, the chain linkage device drives the driven gear, causing the storage bin of the winding tray 4 to rotate synchronously in the opposite direction, forming dynamic rotation compensation. The sheathing material is drawn out from the storage bin and is evenly wound on the surface of the tubular material as the main roller assembly 2 and the storage bin rotate in opposite directions. The traction assembly 7 pulls out the wound material through the roller group or conveyor belt according to the material conveying requirements, ensuring the continuity and stability of the entire winding process. The braking unit 8 brakes in time when needed to ensure the safe operation of the equipment.

[0040] Compared to existing technologies, this equipment significantly improves the uniformity of sheath material winding and the interlayer adhesion on the surface of tubular materials through the effective coordination of a reverse transmission compensation mechanism. In practical applications, such as in the hose manufacturing industry, for hoses requiring high-precision sheath winding, this equipment effectively prevents the sheath material from loosening or shifting due to rotational inertia, ensuring a tight fit of the hose sheath and improving product quality and performance. Furthermore, its unique material guiding and traction design can adapt to tubular materials of different specifications and materials, offering wide applicability and practicality.

[0041] It should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention. For example, the specific dimensions and material of the main roller assembly 2 can be adjusted according to actual production needs; the number and layout of the guide wheels of the material guiding mechanism 6 can also be optimized according to the material characteristics. Furthermore, some specific parameters and material selections involved in this invention, such as the power of the servo motor, the reduction ratio of the reducer, and the thickness of the ultra-high molecular weight polyethylene wear-resistant bushing, are all well-known technologies that those skilled in the art can select and determine according to actual needs, and will not be listed in detail here.

[0042] Finally, in addition to the above structure, in a preferred embodiment, the material guiding mechanism 6 cooperates with a tube material tray 10, which is horizontally rotatably mounted on a fixed frame. During operation, the tube material tray 10 is in a free-rotating state. The radial force generated when the tube is wound with the sheath accumulates over a certain period of time, causing the tube material tray 10 to rotate, thereby performing rotational compensation, offsetting or reducing the radial force on the tube during the winding process, and improving the winding quality.

[0043] Specifically, the tubular material tray 10 is horizontally rotatable on a fixed frame via bearings, and the fixed frame is fixed in a suitable position on the frame 1 to ensure proper alignment and cooperation between the tubular material tray 10 and the guiding mechanism 6. The tubular material tray 10 is provided with grooves or similar fixing structures for placing tubular materials to ensure stable placement of the tubular materials on the tray.

[0044] When the equipment is running, the pipe material tray 10 is in a free-rotating state. As the radial force generated during the winding of the pipe fitting accumulates over a certain period of time, the pipe material tray 10 will be driven to rotate. This rotational compensation can effectively counteract or reduce the radial force on the pipe fitting during the winding process, thereby reducing the shaking or deviation of the pipe fitting during the winding process, and further improving the accuracy and quality of the sheath winding.

[0045] In practical applications, after the tubular material is placed on the tubular material tray 10, the tubular material is guided into the material guiding mechanism 6 and then smoothly conveyed to the position of the main roller assembly 2 for sheath winding. As the winding process proceeds, the radial force on the tubular material gradually accumulates. When it reaches a certain level, the tubular material tray 10 begins to rotate freely to perform rotational compensation, thereby reducing the radial force on the tubular material and improving the winding effect.

[0046] This design offers significant advantages in improving the quality of sheath winding, and is particularly suitable for applications requiring high winding precision, such as the production of wires and cables and hoses. Through the synergistic action of the material tray 10 and the guiding mechanism 6, uneven stress distribution on the tubular components during the winding process can be effectively reduced, ensuring that the sheath material is uniformly and tightly wound onto the surface of the tubular material, thereby enhancing the overall performance and market competitiveness of the product.
