Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for metal wire processing, and specifically to a metal wire take-up device. Background Technology

[0002] In the metal wire processing industry, the winding device is one of the most important pieces of equipment. It is responsible for winding the processed metal wire into coils for easy storage and transportation.

[0003] Traditional metal wire take-up devices typically consist of simple mechanical structures, such as a take-up spool, a brake, and a drive motor. While these devices are simple in structure and inexpensive, they have significant shortcomings in practical applications. For example, during high-speed take-up, inertial forces can cause the wire to vibrate during winding, affecting not only the take-up quality but also potentially causing the wire to break during the winding process. Furthermore, traditional take-up devices often employ fixed tension control methods and typically lack the ability to adjust the take-up tension based on wire diameter and material. In actual operations, there are many types of metal wires with varying diameters, materials, and strengths. This requires the take-up device to be adaptable to the characteristics of the wire. Without effective tension control, uneven tension can occur during winding, easily leading to breakage, bending, and misalignment, thus affecting the quality of the wire during take-up and compromising the performance and appearance of the coil.

[0004] Therefore, developing a metal wire take-up device with a reasonable structure, high stability, and the ability to automatically adjust tension according to the characteristics of the wire is of great significance for improving the quality of wire processing and production efficiency. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a metal wire take-up device to overcome the defects in the above-mentioned technical background.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: A metal wire take-up device includes a structural support, on which a take-up assembly and an adjustable tensioning device are provided. The winding assembly includes a shaft and a winding structure mounted on the shaft; The adjustable tensioning device is located before the winding assembly and includes an assembly plate. The plane of the assembly plate is parallel to the rotating shaft. Two parallel oblong holes are formed on the assembly plate. A slide with a position locking structure is provided on the oblong holes. A movable shaft is provided on the slide. A fixed shaft with a fixed position is provided between the two oblong holes on the assembly plate. Tensioning sleeves are installed on both the movable shaft and the fixed shaft. A wire guide for guiding the wire on the winding structure is also provided between the oblong holes located at the rear of the assembly plate and the winding assembly.

[0007] As a further limitation, the structural support is provided with an adjustable telescopic arm structure between the winding assembly and the adjustable tensioning device, through which the distance between the winding assembly and the adjustable tensioning device can be adjusted.

[0008] As a further limitation, the winding structure is assembled and fixed on the rotating shaft by a detachable assembly structure. The detachable assembly structure is preferably one or a combination of snap fasteners, buckles, keyways, and threaded fasteners to ensure the replaceability of the winding structure and its stability during the winding process.

[0009] As a further limitation, both the movable shaft and the fixed shaft are provided with sleeves with built-in torsion springs, and the tensioning sleeve is assembled and fixed on the sleeves with a detachable assembly structure; the detachable assembly structure is preferably one or a combination of snap fasteners, snap-fit ​​fasteners, keyways, and threaded fasteners.

[0010] As a further limitation, a tension sensor is also provided on the assembly plate surface. The tension sensor cooperates with the tension sleeve on the movable shaft and the fixed shaft to monitor the tension value of the wire as it passes through the tension sleeve in real time.

[0011] As a further limitation, the slide includes a separable assembly block and a base. The top surface of the assembly block is formed with a movable shaft assembly part, the lower two sides are formed with side stepped grooves that match the waist-shaped hole, and the lower bottom surface is formed with a threaded inner hole. The two side surfaces of the base have pressing surfaces that match the side stepped grooves, and a through threaded hole that matches the threaded inner hole is formed in the middle position of the base. By assembling a locking screw in the through threaded hole, the screw part of the locking screw passes through the through threaded hole and is threaded into the threaded inner hole, thereby locking the assembly block and the base, realizing the detachable assembly of the slide structure.

[0012] As a further limitation, the tensioning sleeve has an annular guide groove formed on the tube body, and the annular guide groove has an inwardly concave arc shape in its circumferential cross-section.

[0013] As a further limitation, the structural support is provided with a drive motor and an emergency stop brake device. The drive motor is connected to the rotating shaft and is used to drive the rotating shaft and the winding structure mounted thereon to rotate and take in the wire. The emergency stop brake device is connected to the rotating shaft and is used to stop the rotating shaft from rotating when the wire breaks or the winding structure is fully wound. The drive motor is preferably a variable frequency motor. By adjusting the speed of the variable frequency motor, the winding speed can be adjusted to meet the winding requirements of different wires.

[0014] Beneficial Effects: This utility model discloses a metal wire take-up device. By incorporating an adjustable tensioning mechanism, the device utilizes a tensioning sleeve mounted on a movable shaft and a fixed shaft to tension the wire. The adjustable position of the sliding block on the oblong hole allows for precise adjustment of the contact pressure between the tensioning sleeve and the metal wire, achieving flexible control of the wire tension. This effectively solves the problem of unreasonable tension control in traditional take-up devices. The device can flexibly adjust the tension according to the diameter and material of different wires, ensuring that the wire maintains appropriate tension during the winding process on the winding structure. This improves the take-up quality, meets the winding requirements of various wires, and significantly reduces the probability of defects such as breakage, bending, and misalignment during the winding process.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] See Figure 1 , Figure 2A preferred embodiment of a metal wire take-up device includes a take-up assembly and an adjustable tensioning device arranged in sequence. The wire 1 to be taken up enters the metal wire take-up device after being guided by the straightening guide roller 2, and is smoothly pulled to the take-up assembly for take-up after being tensioned by the adjustable tensioning device.

[0020] In this embodiment, the main support of the adjustable tensioning device is the mounting plate 5, while the main support of the winding assembly is the L-shaped bracket 16. Both the L-shaped bracket 16 and the mounting plate 5 are made of steel to ensure good stability of the device during use.

[0021] The lower part of the assembly plate 5 is connected to the structural support via connectors. These connectors can be existing technologies, such as bolts, nuts, or welded components, ensuring that the assembly plate 5 is securely mounted on the structural support. The lower right side of the assembly plate 5 is connected to the L-shaped bracket 16 via an adjustable telescopic frame 9. The adjustable telescopic frame 9 allows for flexible adjustment of the distance between the assembly plate 5 and the L-shaped bracket 16 to accommodate the winding requirements of wires 1 of different lengths.

[0022] Two parallel oblong holes 3 are formed on the assembly plate 5, which allow the components mounted on them to be positionally adjustable. A first movable shaft assembly 4 and a second movable shaft assembly 7 are respectively provided on the two oblong holes 3. Both movable shaft assemblies are mounted on the oblong holes 3 through a slide structure. The slide structure is designed to allow the movable shaft assemblies to slide along the length of the oblong holes 3 and to be fixed by a position locking structure, thereby precisely adjusting the relative position between the movable shaft assemblies and the metal wire 1.

[0023] Specifically, the structural arrangement of the first movable shaft assembly 4 and the second movable shaft assembly 7 assembled at the waist-shaped hole 3 is as follows: Figure 2 As shown, the slide structure includes a separable assembly block 21 and a base 19. The top surface of the assembly block 21 is formed with a mounting portion for a movable shaft 22, which is used to assemble the movable shaft 22, allowing the movable shaft 22 to be securely mounted on the assembly block 21. A threaded inner hole is formed at the lower center of the assembly block 21, and stepped side grooves matching the waist-shaped hole 3 are formed on both lower sides. The design of these stepped side grooves allows the assembly block 21 to be positioned such that… Figure 2 The pattern shown is fitted into the waist-shaped hole 3 and can slide along the length of the waist-shaped hole 3 in a loose state. The lower bottom surface of the assembly block 21 has a threaded inner hole formed.

[0024] The base liner 19 is a plate structure with a clamping surface on its outer edge that matches the stepped groove on the side. This surface, through its tight fit with the stepped groove, prevents the assembly block 21 from sliding on the waist-shaped hole 3 after it has slid to the appropriate position. A threaded hole matching the threaded inner hole is formed in the middle of the base liner 19. This threaded hole corresponds to the position of the threaded inner hole on the assembly block 21. By installing a locking screw 20 in the threaded hole, the screw shank of the locking screw 20 passes through the threaded hole and engages with the threaded inner hole, thereby locking the assembly block 21 to the base liner 19 and achieving detachable assembly of the slide structure.

[0025] This sliding seat structure design not only facilitates the position adjustment of the movable shaft assembly on the waist-shaped hole 3, but also ensures the stability of the movable shaft assembly after it is adjusted into place, providing a reliable guarantee for the tension adjustment of the wire 1. At the same time, in order to improve the stability of the bottom liner 19 when pressed, a stepped blind groove is formed on its outer upper surface, and a rubber anti-slip pad 18 is installed at the stepped blind groove position to serve as the contact surface with the lower surface of the mounting plate 5 on the outer side of the waist-shaped hole 3.

[0026] Both the first movable shaft assembly 4 and the second movable shaft assembly 7 are provided with sleeves 23 with built-in torsion springs on their corresponding movable shafts 22. These sleeves 23 are used to assemble the tensioning sleeve 24. The tensioning sleeve 24 is assembled and fixed to the sleeve 23 via a detachable assembly structure. In different embodiments, the detachable assembly structure can be one or a combination of snap-fit, snap-fit, keyway, and threaded fasteners. This detachable assembly structure design allows the tensioning sleeve 24 to be easily assembled onto the sleeve 23 and can be replaced or adjusted as needed.

[0027] A fixed shaft is also provided on the fixed shaft assembly 6. Both the fixed shaft and the movable shaft 22 can rotate around the shaft through the bearing seat. The fixed shaft is also provided with a sleeve 23 and a tensioning sleeve 24 with the same structure. The only difference between the fixed shaft and the movable shaft 22 is that the base of the fixed shaft is fixedly mounted on the assembly plate 5 and cannot be adjusted in position.

[0028] The tensioning sleeve 24 has an annular guide groove 25 formed on its body. The annular guide groove 25 has an inwardly concave arc-shaped cross-section. The annular guide groove 25 is designed to guide the metal wire 1 to slide on the tensioning sleeve 24 and to reduce the frictional resistance between the metal wire 1 and the tensioning sleeve 24, so that the metal wire 1 can pass smoothly through the tensioning sleeve 24 during the winding process.

[0029] A wire guide 8 is also provided on the assembly plate 5 between the rear-positioned waist-shaped hole 3 and the winding assembly. The wire guide 8 has opposing bidirectional tapered holes with smooth surfaces to reduce resistance and wear on the wire 1. The wire guide 8 is mounted on the guide rod 11 and can be moved along the guide rod 11. The guide rod 11 is fixedly mounted on the assembly plate 5 on both sides by telescopic brackets 10. The function of the wire guide 8 is to smoothly guide the wire 1 onto the winding structure, prevent the wire 1 from shifting or shaking during winding, and accurately wind it onto the winding structure.

[0030] The design of the wire guide 8 can be replaced and adjusted according to actual needs to adapt to the winding requirements of metal wires 1 of different diameters and materials.

[0031] In the winding assembly of this embodiment, an electric drive assembly 12 with a coupling 13 is mounted on the outer side of the vertical edge of the L-shaped bracket 16, and a rotating shaft 14 is correspondingly arranged on the inner side of the vertical edge of the L-shaped bracket 16. One end of the rotating shaft 14 is mounted on the inner surface of the L-shaped bracket 16 through a bearing seat, and the other end extends out of the outer side of the L-shaped bracket 16 and is connected to the coupling 13. The power unit in the electric drive assembly 12 is a variable frequency motor, and its output shaft is connected to the coupling 13. The driving force of the motor is transmitted to the rotating shaft 14 through the coupling 13, thereby driving the rotating shaft 14 to rotate.

[0032] A winding structure, which is a reel 17 in this embodiment, is mounted on the rotating shaft 14. The reel 17 is connected to the rotating shaft 14 via a detachable assembly structure. In this embodiment, the detachable assembly structure is preferably a keyway and key mating structure. By opening a keyway on the rotating shaft 14 and setting a key that matches the keyway in the mounting hole of the reel 17, a stable assembly of the reel 17 on the rotating shaft 14 can be achieved, while also facilitating the replacement of the reel 17.

[0033] In addition, the metal wire take-up device in this embodiment also includes an emergency stop brake device, which is also connected to the rotating shaft 14. This device is used to quickly stop the rotating shaft 14 from rotating when the wire breaks or when the reel 17 is fully wound, ensuring the safety and stability of the take-up operation. The emergency stop brake device can be designed using an electromagnetic or mechanical braking structure, the specific choice depending on the requirements of the actual application scenario.

[0034] In addition, a tension sensor (not shown in the figure) is also installed on the assembly plate 5. The tension sensor works in conjunction with the tension sleeve 24 on the movable shaft assembly and the fixed shaft assembly to monitor the tension value of the wire 1 as it passes through the tension sleeve 24 in real time. Through the feedback from the tension sensor, the operator can understand the tension status of the wire 1 in real time and adjust the position of the movable shaft assembly as needed to ensure that the wire 1 maintains appropriate tension during the winding process.

Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
