Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, specifically to a cable insulation layer winding reel. Background Technology
[0002] In the cable production process, insulation wrapping is a key step to ensure the electrical and safety performance of the cable. By wrapping an insulation layer around the outside of the cable core, the insulation performance and signal shielding performance of the cable are improved. In the existing technology, a rotating unwinding reel is usually used to install and unwind the insulation material master roll. The rotation of the reel causes the insulation material released from the unwinding component to wrap around the cable core along a predetermined path. This method can basically meet the basic requirements of cable insulation wrapping and, to a certain extent, ensure the continuity of cable production.
[0003] However, existing technologies generally lack a stable guiding structure for the unwinding path of the insulation material. They can only achieve basic placement and rotation unwinding functions of the insulation roll. The rotation of the rotating disk relies on a simple drive structure. During the process of the insulation material being fed from the unwinding component to the cable core, due to the lack of stable support and precise guidance components for the rotating disk, the insulation material only relies on its own tension to naturally extend to the cable core. It is difficult to constrain the direction of the material, which makes it easy for the material to deviate or run off course during transmission. This not only reduces the stability of the wrapping process, but may also lead to defects such as uneven insulation thickness and incomplete coverage in the finished cable, affecting product performance and increasing the defect rate. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the objective is to provide a cable insulation layer winding reel.
[0005] The technical solution is as follows: A cable insulation layer winding reel includes a fixed base, a rotating ring, a connecting frame, a lead wire die, a driven wheel, a driving wheel, a drive motor, a pulley, a transmission belt, and a rotating wheel. The fixed base has a circular groove. An annular track is arranged around the outer edge of the circular groove at the front of the fixed base. The rotating ring is rotatably mounted on the annular track. The connecting frame is mounted on the fixed base. A lead wire die is located at the end of the connecting frame. A through-hole is formed inside the lead wire die, and the lead wire hole is concentric with the rotating ring. One side of the front of the fixed base is annular and has multiple driven wheels and multiple driving wheels rotatably mounted. Both the driven wheels and driving wheels are arranged around the outer side of the rotating ring, and both the driven wheels and driving wheels are aligned with the rotating ring. The rolling contact mechanism has multiple pulleys at the rear of the fixed base, with the number of pulleys matching the number of drive pulleys. Each pulley is connected to a drive pulley via a rotating shaft. A transmission belt is wound around the outer sides of the pulleys. A drive motor is located at the lower rear of the fixed base, and the output shaft of the drive motor is connected to one of the pulleys. The drive motor drives each drive pulley to rotate synchronously, causing the rotating ring to rotate along the circular track. A unwinding reel is installed on the front side of the rotating ring. The unwinding reel is used to install the insulation layer roll required for wrapping. A limit guide mechanism is provided on the front side of the rotating ring near the unwinding reel. The limit guide mechanism guides the insulation layer material unwound from the unwinding reel toward the lead wire die.
[0006] As an improvement to the above solution, the unwinding reel includes a mounting plate, a rotating drum, locking blocks, insert rods, pressure blocks, a top plate, and a spring. The mounting plate is rotatably mounted on one side of the front of the rotating ring, and the rotating drum is fixedly mounted on the front side of the mounting plate. The top plate is slidably mounted on the rear of the rotating drum, and the rear end of the top plate is connected to a spring. The other end of the spring is connected to the rotating drum. An insert rod is inserted into the rotating drum. Two grooves are provided on the inner wall of the rotating drum. The two grooves extend along the axial direction of the rotating drum, and their rear ends are bent in the same circumferential direction to form a hook-shaped structure. Two locking blocks corresponding to the size of the grooves are provided at the end of the insert rod. A pressure block is provided on the end of the insert rod away from the locking blocks. When the insert rod is inserted into the rotating drum, the locking blocks slide along the axial part of the grooves. The rear end of the insert rod first contacts the top plate and presses the top plate to move backward. When the locking blocks slide to the bend of the groove, rotating the insert rod can make the locking blocks engage in the hook-shaped structure of the groove to fix the insert rod to the rotating drum.
[0007] As an improvement to the above solution, the limiting guide mechanism includes an arc-shaped spring, a second rotating wheel, a first guide seat, a guide rod, another second guide seat, and an adjusting screw. An arc-shaped groove is formed on the front side of the rotating ring near the unwinding reel. A slider is slidably mounted within the arc-shaped groove, and a first rotating wheel is rotatably mounted on the slider. An arc-shaped spring is located within the arc-shaped groove, with its two ends connected to the slider and the rotating ring, respectively. An extension portion extending towards the center of the ring is located on the unwinding reel side of the front side of the rotating ring. At least one second rotating wheel rotates on the front side of the extension portion of the rotating ring. A guide seat 1 and a guide rod are fixedly provided at the front end of the ring extension. A guide seat 2 is provided on the guide rod in a sliding manner. Both guide seats 1 and guide seats 2 have guide grooves. Guide seats 1 and guide seats 2 are arranged in a front-to-back manner. Through the guide grooves in guide seats 1 and guide seats 2, a guide path is formed on the rotating ring with the end facing the lead wire die head. An adjusting screw is rotatably provided on the extension of the rotating ring. The adjusting screw is screwed to the lower part of guide seat 2. Rotating the adjusting screw will cause guide seat 2 to slide back and forth on the guide rod.
[0008] As an improvement to the above solution, it also includes a pressure plate and springs. A pressure plate is slidably mounted on the pressure block. The pressure plate has a circular hole that matches the size of the outer wall of the rotating cylinder. Multiple springs are arranged circumferentially on the pressure plate. The other end of each spring is connected to the pressure block. When the insertion rod is fixed to the rotating cylinder, the pressure plate abuts against the front end of the insulating layer roll sleeved on the rotating cylinder under the elastic force of the springs to achieve axial positioning.
[0009] As an improvement to the above solution, it also includes a swing arm, a torsion spring, and a pressure roller. A swing arm is rotatably provided on one side of the front part of the rotating ring. The swing arm is located on the side close to the mounting plate. A pressure roller is provided at the end of the swing arm. A torsion spring is provided at the rotatable connection between the swing arm and the rotating ring. Under the action of the torsion spring, the pressure roller at the end of the swing arm maintains a swinging state toward the mounting plate to press against the outer circumferential surface of the insulating layer roll sleeved on the rotating drum.
[0010] As an improvement to the above solution, anti-slip textures are provided on both the front end face of the mounting plate and the rear end face of the pressure plate.
[0011] The beneficial effects of this utility model are as follows: By setting a limiting and guiding mechanism, this utility model can provide a stable guiding effect on the insulation material released by the unwinding reel during the wrapping process, ensuring that the insulation material maintains a preset path during the process of being guided to the lead wire die head, reducing the impact of material deviation on the wrapping accuracy. Compared with the material deviation problem caused by the lack of a special guiding structure in the simple rotating disk in the prior art, this utility model effectively improves the stability and consistency of cable insulation wrapping.
[0012] The unwinding reel of this utility model adopts a structure consisting of a rotating drum, insert rod, groove, and locking block, combined with the elastic action of the top plate and spring 1, to achieve rapid installation and fixation of the insulation layer roll mother roll. Simply insert the insert rod into the rotating drum and rotate it to complete the positioning of the mother roll. The operation is convenient and efficient, solving the problem of cumbersome operation and long time consumption when installing the mother roll in the simple unwinding components of the prior art, and significantly improving the efficiency of mother roll replacement.
[0013] This invention utilizes an outer circumferential pressing mechanism comprised of a swing arm, a torsion spring, and a pressure roller. Under the elastic force of the torsion spring, the pressure roller is always pressed against the outer circumferential surface of the insulation roll. As the insulation roll is unwound, it automatically adapts to changes in its diameter and maintains stable pressure, avoiding tension instability caused by material relaxation during unwinding. Compared to the material loosening problem that easily occurs with simple rotating discs lacking a pressing structure in existing technologies, this invention ensures the uniformity of the insulation material unwinding.

Detailed Implementation
[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0022] Example 1
[0023] A cable insulation layer winding reel, such as Figure 1-4 As shown, the assembly includes a fixed base 1, a rotating ring 2, a connecting frame 21, a lead wire die head 22, a driven wheel 3, a driving wheel 4, a drive motor 5, a pulley 51, a transmission belt 52, and a rotating wheel 6. The fixed base 1 has a circular groove. An annular track is provided around the outer edge of the groove at the front of the fixed base 1. The rotating ring 2 is rotatably mounted on the annular track. The annular track precisely constrains the rotation trajectory of the rotating ring 2, ensuring that the rotating ring 2 always rotates stably along a preset center. The connecting frame 21 is provided on the fixed base 1, and its end has a... The lead wire die 22 has a through-hole, and the lead wire hole is concentric with the rotating ring 2, allowing the cable core to pass through the lead wire hole and remain concentric with the rotating ring 2, providing a stable center reference for the wrapping of the insulation material. The front side of the fixed base 1 is annular and rotatably equipped with multiple driven wheels 3 and multiple driving wheels 4. Both driven wheels 3 and driving wheels 4 are arranged around the outer side of the rotating ring 2, and both are in rolling contact with the rotating ring 2. The driven wheels 3 and driving wheels 4 together form a ring around the rotating ring 2. The circumferential clamping ensures both the flexibility of the rotating ring 2 and enhances its stability during rotation, preventing radial sway. Multiple pulleys 51 are located at the rear of the fixed base 1, the number of which matches the number of drive pulleys 4. Each pulley 51 is connected to a drive pulley 4 via a rotating shaft. A transmission belt 52 is wound around the outer sides of the pulleys 51. A drive motor 5 is located at the lower rear of the fixed base 1, and the output shaft of the drive motor 5 is connected to one of the pulleys 51, causing the drive motor 5 to rotate. The power is transmitted to the other pulleys 51 via the transmission belt 52, which in turn drives each drive wheel 4 to rotate synchronously. The friction between the drive wheel 4 and the rotating ring 2 drives the rotating ring 2 to rotate smoothly along the circular track. A unwinding reel is installed on the front side of the rotating ring 2. The unwinding reel is used to install the insulation layer roll required for wrapping. A limit guide mechanism is provided on the front side of the rotating ring 2 near the unwinding reel. The limit guide mechanism guides the insulation layer material unwound in the unwinding reel to the lead wire die head 22 side, ensuring that the insulation layer material maintains a stable direction during transmission.
[0024] Among them, such as Figure 1 , Figure 4 and Figure 6As shown, the unwinding reel includes a mounting plate 31, a rotating drum 311, a locking block 3101, an insert rod 312, a pressure block 313, a top plate 32, and a spring 33. The mounting plate 31 is rotatably mounted on one side of the front of the rotating ring 2, allowing the mounting plate 31 to rotate synchronously with the rotating ring 2 while also rotating flexibly relative to the rotating ring 2 to adapt to the unwinding speed. The rotating drum 311 is fixedly mounted on the front side of the mounting plate 31. The rotating drum 311 is used to mount the insulation layer roll and provides an installation reference for the insulation layer roll. A top plate 32 is slidably mounted on the rear part of the rotating cylinder 311. A spring 33 is connected to the rear end of the top plate 32, and the other end of the spring 33 is connected to the rotating cylinder 311. The spring 33 always applies a forward elastic force to the top plate 32. A rod 312 is inserted into the rotating cylinder 311. Two grooves 3100 are formed on the inner wall of the rotating cylinder 311. The two grooves 3100 extend along the axial direction of the rotating cylinder 311, and their rear ends are bent in the same circumferential direction to form a hook-shaped structure. The rod 312... Two locking blocks 3101 corresponding to the dimensions of the groove 3100 are provided at the end of the insertion rod 312. A pressure block 313 is provided at the end of the insertion rod 312 away from the locking blocks 3101. When the insertion rod 312 is inserted into the rotating cylinder 311, the locking blocks 3101 slide along the axial part of the groove 3100. The rear end of the insertion rod 312 first contacts the top plate 32 and presses the top plate 32 backward, causing the spring 33 to compress and store force. When the locking blocks 3101 slide to the bend of the groove 3100, the insertion rod 312 rotates. 12 allows the locking block 3101 to be engaged in the hook-shaped structure of the groove 3100 to fix the insertion rod 312 to the rotating drum 311. At this time, the elastic force of the spring 33 acts on the insertion rod 312 through the top plate 32, so that the locking block 3101 is tightly against the inner wall of the hook-shaped structure of the groove 3100 to prevent the insertion rod 312 from loosening. At the same time, the pressure block 313 cooperates with the mounting plate 31 to form an axial clamp on the insulating layer roll sleeved on the rotating drum 311, so as to realize the rapid installation and stable fixation of the insulating layer roll.
[0025] like Figure 1 , Figure 4As shown in Figure 5, the limiting and guiding mechanism includes an arc-shaped spring 61, a second rotating wheel 62, a first guide seat 63, a guide rod 64, a second guide seat 65, and an adjusting screw 66. An arc-shaped groove is formed on the front side of the rotating ring 2 near the unwinding reel. A slider is slidably mounted within the arc-shaped groove, and a first rotating wheel 6 is rotatably mounted on the slider. An arc-shaped spring 61 is also located within the arc-shaped groove. Both ends of the arc-shaped spring 61 are connected to the slider and the rotating ring 2, respectively. The arc-shaped spring 61 applies an elastic force to the slider, ensuring that the first rotating wheel 6 remains in contact with the outer circumference of the insulating layer roll on the unwinding reel. As the diameter of the insulation roll decreases, the slider slides adaptively along the arc-shaped groove, ensuring that the first roller 6 continuously provides initial guidance for the unwinding direction of the insulation material. The rotating ring 2 has an extension on one side of the unwinding tray, extending towards its center. Two rollers 62 are rotatably mounted on the front side of the extension of the rotating ring 2. The rollers 62 and the first roller 6 cooperate to form a continuous guide path, further constraining the direction of the insulation material and reducing deviation during material transport. A guide seat 6 is fixedly mounted at the front end of the extension of the rotating ring 2. 3 and guide rod 64, with guide seat 2 65 sliding back and forth on guide rod 64. Both guide seat 1 63 and guide seat 2 65 have guide grooves. Guide seat 1 63 and guide seat 2 65 are arranged opposite each other. The guide grooves in guide seat 1 63 and guide seat 2 65 together form a guide path on the rotating ring 2 with the end facing the lead wire die head 22. The insulating material passes through the guide grooves between rotating wheel 1 6 and rotating wheel 2 62, and between guide seat 1 63 and guide seat 2 65 in sequence, realizing multi-segment guidance of the insulating material. To limit and reduce lateral movement of materials during transmission, an adjusting screw 66 is rotatably provided on the extension of the rotating ring 2. The adjusting screw 66 is screwed to the lower part of the guide seat 65. When the adjusting screw 66 is rotated, its threaded transmission drives the guide seat 65 to slide back and forth along the guide rod 64, thereby adjusting the relative distance between the guide seat 63 and the guide seat 65. This is to match insulating layer materials of different widths, ensuring that materials of different widths can be stably clamped and guided, and reducing the jumping phenomenon caused by the mismatch of material widths during wrapping.
[0026] When installing the master roll, the operator first places the insulation roll on the rotating drum 311, so that the rear end of the insulation roll abuts against the mounting plate 31; then inserts the end of the insertion rod 312 with the locking block 3101 into the opening of the rotating drum 311. At this time, the locking block 3101 slides axially along the groove 3100 on the inner wall of the rotating drum 311, and the end of the insertion rod 312 gradually contacts the top plate 32 and presses the top plate 32 to move backward, and the spring 33 is compressed and stores force accordingly. When the locking block 3101 slides to the bend of the groove 3100, the rotating rod 312 causes the locking block 3101 to engage with the hook-shaped structure of the groove 3100. Under the elastic reaction force of the spring 33, the top plate 32 pushes the rod 312 to make the locking block 3101 tightly engage with the groove 3100, thereby fixing the rod 312 and the rotating drum 311. At the same time, the pressure block 313 cooperates with the mounting plate 31 to axially clamp the insulation layer roll, completing the installation of the mother roll.
[0027] When laying the material, first draw out the free end of the insulating layer material from the insulating layer roll, let it pass around the outside of the first rotating wheel 6 and the second rotating wheel 62 in sequence, then pass through the guide grooves of the first guide seat 63 and the second guide seat 65, and finally lead it to the lead hole of the lead wire die head 22; if the width of the insulating layer material is different, the adjusting screw 66 can be rotated to drive the second guide seat 65 to slide back and forth along the guide rod 64 through the thread transmission, adjust the distance between the first guide seat 63 and the second guide seat 65 so that the guide groove is adapted to the width of the material, and ensure that the material is stably clamped.
[0028] During processing, the cable core passes through the lead hole of the lead die 22 and is continuously conveyed; the drive motor 5 is started, and its output shaft drives the connected pulley 51 to rotate. The power is transmitted to the other pulleys 51 through the transmission belt 52. Each pulley 51 drives the corresponding driving wheel 4 to rotate synchronously through the rotating shaft. The friction between the driving wheel 4 and the rotating ring 2 drives the rotating ring 2 to rotate along the circular track. The driven wheel 3 rotates with the rotating ring 2 and forms circumferential support for it, ensuring that the rotating ring 2 rotates smoothly. During the rotation of the rotating ring 2, the unwinding reel rotates synchronously with it. The insulation material is continuously unwound under the combined action of the centrifugal force and the traction force of the cable core. During this process, the arc spring 61 keeps the first wheel 6 in contact with the outer circumference of the insulation roll through the slider, and the second wheel 62 provides initial guidance for the material. The guide grooves of the first guide seat 63 and the second guide seat 65 further constrain the material's direction, ensuring that the insulation material is always guided to the lead wire die head 22 along the preset path. Finally, the insulation material rotates uniformly around the cable core under the drive of the rotating ring 2, achieving a tight wrap around the outside of the cable core, forming a cable insulation layer with uniform thickness and stable insulation performance.
[0029] Example 2
[0030] Based on Example 1, such as Figure 1 and Figure 6As shown, it also includes a pressure plate 34 and springs 35. The pressure plate 34 is slidably mounted on the pressure block 313. The pressure plate 34 can slide freely relative to the pressure block 313 along the axial direction of the insertion rod 312. The pressure plate 34 has a circular hole that matches the outer wall size of the rotating drum 311, so that the pressure plate 34 is always guided by the rotating drum 311 during the sliding process to avoid deviation. Multiple springs 35 are arranged circumferentially on the pressure plate 34. The other end of each spring 35 is connected to the pressure block 313. When the insertion rod 312 is fixed to the rotating drum 311, the pressure plate 34 abuts against the front end of the insulating layer roll sleeved on the rotating drum 311 under the elastic force of the springs 35 to achieve axial limiting. Through the elastic extension and contraction characteristics of the springs 35, it can automatically adapt to insulating layer rolls of different widths, ensuring that a stable axial pressure can be applied to insulating layer rolls of various widths, and preventing the insulating layer roll from axially shifting during the unwinding process.
[0031] like Figure 1 and Figure 4 As shown, it also includes a swing arm 7, a torsion spring 71, and a pressure roller 72. The swing arm 7 is rotatably provided on one side of the front part of the rotating ring 2. The swing arm 7 can swing freely around its connection point with the rotating ring 2. The swing arm 7 is located on the side close to the mounting plate 31. The end of the swing arm 7 is provided with a pressure roller 72, which can rotate freely relative to the swing arm 7. The torsion spring 71 is provided at the rotatable connection between the swing arm 7 and the rotating ring 2. The two ends of the torsion spring 71 are fixedly connected to the swing arm 7 and the rotating ring 2, respectively. Under the torsion of the torsion spring 71, the pressure roller 72 at the end of the swing arm 7 maintains a swinging state towards the mounting plate 31 to press against the outer circumferential surface of the insulating layer roll sleeved on the rotating drum 311. As the diameter of the insulating layer roll gradually decreases during the unwinding process, the torsion of the torsion spring 71 will push the swing arm 7 to swing continuously, so that the pressure roller 72 always fits tightly against the outer circumferential surface of the insulating layer roll, maintaining a stable pressure on the insulating layer roll, avoiding radial shaking of the insulating layer roll due to centrifugal force or vibration, and ensuring a smooth and orderly unwinding process.
[0032] In a preferred embodiment, such as Figure 1 , Figure 4 and Figure 6 As shown, anti-slip textures are provided on the front end face of the mounting plate 31 and the rear end face of the pressure plate 34. When the insulation roll is clamped between the mounting plate 31 and the pressure plate 34, the anti-slip textures can increase the friction with the end of the insulation roll, further preventing the insulation roll from rotating or sliding relative to the rotating ring 2 during rotation, ensuring that the unwinding speed of the insulation roll is consistent with the operating rhythm of the equipment, and improving the wrapping accuracy.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
