Description

Technical Field

[0001] This application relates to the field of cable manufacturing technology, and more specifically, to a tension control device, a winding rotary machine, and rigid cable manufacturing equipment. Background Technology

[0002] During the cable production process, it is necessary to wrap the cable with wire to protect and insulate it.

[0003] In related technologies, when winding wire, a separate tensioning structure is usually used to tension the wire to be wound, and then the wire is wound around the wire after tensioning. However, this winding method is prone to problems such as the wire not being fully tensioned, resulting in a loose winding or uneven winding. Utility Model Content

[0004] In order to at least address some of the deficiencies in the related technologies, this application provides a tension control device, a winding and rotating machine, and a rigid cable production equipment.

[0005] To achieve the above objectives, this application provides a tension control device for use on a winding machine to control the tension of the wire during winding. The tension control device includes a shaft, with a mounting platform at one end of the shaft near the winding machine. A guide portion is provided on the mounting platform, extending towards the winding machine. A threading hole is formed at the center of the guide portion, penetrating the mounting platform and the shaft, through which the wire wound by the winding machine passes. A tapered groove communicating with the threading hole is also provided at the center of the guide portion.

[0006] Furthermore, the tension control device also includes a tensioning section, through which the wire on the winding rotary machine is tensioned and then extends into the conical groove, and along the inner wall of the conical groove to the wire.

[0007] This application also provides a winding and rotating machine, including a frame and the tension control device described in any of the above embodiments. The frame is provided with an inlet and an outlet, and the tension control device is disposed at the outlet. A winding assembly is disposed between the inlet and the outlet, and the wire enters the winding assembly from the inlet, passes through the tension control device, and exits from the outlet.

[0008] Furthermore, the winding assembly includes a rotating frame rotatably mounted on the inlet section. A wire storage section is provided on the rotating frame facing the outlet section for storing the wire, which passes through the tension control device and is wound around the wire.

[0009] Furthermore, a support rod extends from the rotating frame toward the wire outlet, and a tensioning part is provided on the support rod to tension the wire extending from the wire storage part.

[0010] Furthermore, multiple wire storage units are evenly distributed circumferentially on the rotating frame, and multiple support rods and tensioning units are also evenly distributed circumferentially.

[0011] This embodiment also provides a rigid cable production equipment, including a pulling device, a shaping device, and a winding rotary machine as described in any of the above embodiments, wherein the pulling device pulls the wire sequentially through the winding rotary machine and the shaping device.

[0012] Furthermore, at least two winding rotary machines are provided, and the rotation directions of adjacent winding rotary machines are opposite.

[0013] Furthermore, a gap is provided between adjacent winding and rotating machines to allow observation of the winding of the wire.

[0014] Furthermore, the rigid cable production equipment also includes a drive device, which includes a power component and a transmission component. The power component drives the winding rotary machine to rotate through the transmission component.

[0015] With the above technical solution, when the winding machine is used to wind cables, the shaft of the tension control device is installed at the cable outlet position of the winding machine, and the cable passes through the threading hole on the tension control device. When the wire to be wound extends into the threading hole, it is restricted by the conical groove, moves along the inner wall of the conical groove into the threading hole, and connects to the cable, thus performing the winding operation on the cable.

[0016] The tension control device of this application guides and restricts the angle of the wire when it comes into contact with the cable through a conical groove, further tightening the wire to prevent it from being loose during winding and ensuring the winding quality of the cable. At the same time, controlling the posture of the wire during winding also ensures that the wire is wound more evenly on the cable.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] This application provides a tension control device to solve the problem of loose or uneven cable winding in related technologies.

[0029] Please see Figure 1 , Figure 2 A tension control device is disclosed for use on a winding machine to control the tension of the wire during winding. The tension control device includes a shaft 100, with a mounting platform 110 at one end of the shaft 100 near the winding machine 200. A guide portion 120 is provided on the mounting platform 110, extending towards the winding machine 200. A wire-passing hole 121 is provided at the center of the guide portion 120, penetrating both the mounting platform 110 and the shaft 100, through which the wire wound by the winding machine 200 passes. A tapered groove 122 communicating with the wire-passing hole 121 is also provided at the center of the guide portion 120.

[0030] During the cable winding operation, the cable moves from the inlet section to the outlet section of the winding rotary machine 200, and the wire is wound around the cable during the cable movement. Specifically, in this embodiment, the tension control device is installed at the outlet section 220 of the winding rotary machine 200, and correspondingly, the winding position of the wire and the cable is also installed in the tension control device.

[0031] When the wire extends from the winding machine 200 and along a preset path until it reaches the position of the tension control device, the wire will extend into the wire hole 121 along the tapered groove 122 at one end of the wire hole 121. The inclination angle of the tapered groove 122 is set within a preset range, allowing the wire to smoothly enter the wire hole 121, and the wire is effectively guided and restricted by the inner wall of the tapered groove 122 during its insertion.

[0032] After the thread enters the threading hole 121, it connects with the cable. At this time, the winding rotary machine 200 continues to rotate, driving the thread to be tightly wound around the cable in a spiral manner. During this process, the guiding and restraining function of the conical groove 122 ensures that the posture of the thread is stable and controllable, thereby guaranteeing the quality and performance of the final product.

[0033] In this embodiment, when the wire is wound onto the cable, it is constrained by the conical groove 122. On the one hand, the conical groove 122 changes the trajectory of the wire, which is equivalent to further tightening the wire, ensuring that the wire is not directly wound onto the cable in a slack state, thus stabilizing the winding quality of the cable. On the other hand, the conical groove 122 also allows the wire to contact the cable in the same posture. That is to say, when the wire is wound onto the cable, the tension and winding angle of the wire remain stable, thereby making the uniformity and density of the wire winding better, and the winding quality more stable.

[0034] In one embodiment, exemplarily, such as Figure 1 , Figure 2 As shown, the tension control device also includes a tensioning section 233. After the wire on the winding rotary machine 200 is tensioned by the tensioning section 233, it extends into the conical groove 122 and extends along the inner wall of the conical groove 122 onto the wire. After extending out, the wire on the winding rotary machine 200 is first tensioned by the tensioning section 233, and then extends into the conical groove 122. The conical groove 122 guides the wire and further tensions it, ensuring that the wire is in a taut state before contacting the cable, and that the tension state of the cable's tilt angle is stable and controllable.

[0035] When the wire contacts the cable in this state and begins to wind, it adheres tightly and evenly to the surface of the cable, thereby improving the overall strength and durability of the cable and ensuring that the cable maintains good electrical performance and transmission efficiency during subsequent use. Therefore, through the synergistic action of the winding rotary machine 200, the tensioning part 233, and the conical groove 122, the cable winding process can be made efficient and of stable quality.

[0036] It is understood that in this embodiment, the specific structure of the tensioning part 233 is not limited. The tensioning part 233 can be set to any commonly used tensioning structure or tensioning device according to actual needs, as long as it can meet the requirements of this embodiment and tension the thread.

[0037] Please see Figure 3 This application also provides a winding and rotating machine 200, including a frame and a tension control device as described in any of the above embodiments. The frame is provided with an inlet section 210 and an outlet section 220, and the tension control device is disposed in the outlet section 220. A winding assembly is disposed between the inlet section 210 and the outlet section 220. The wire enters the winding assembly from the inlet section 210, passes through the tension control device, and exits from the outlet section 220.

[0038] In this way, when the wire is wound, the wire is sent to the inlet section 210 of the winding rotary machine 200 by external traction equipment, wire feeding equipment and other equipment, and the wire continues to move towards the outlet section 220. When the wire passes between the inlet section 210 and the outlet section 220, the winding assembly performs the winding operation on the wire, and the wound wire contacts the wire in the tension control device at the outlet section 220 to ensure that the wire is wound evenly on the wire.

[0039] In one embodiment, exemplarily, such as Figure 3As shown, the winding assembly includes a rotating frame 230, which is rotatably mounted on the wire inlet 210. A wire storage section 231 is provided on the rotating frame 230 facing the wire outlet 220 for storing the wire. The wire passes through a tension control device and is wound onto the wire. When the wire passes through the winding assembly, the rotating frame 230 rotates, causing the wire storage section 231 to rotate as well. The rotation of the wire storage section 231 is the process of the wire being wound onto the wire.

[0040] During the winding process, the quality of the winding is mainly affected by the wire's moving speed, the rotation speed of the winding assembly, and the tension of the wire. In this embodiment, the wire's moving speed remains constant, and the wire is tensioned sequentially by the tensioning part 233 and the tension control device before winding. The rotation speed of the rotating frame 230 is stable, which ensures that the quality of the wire wound on the wire is stable and the winding is uniform.

[0041] In one embodiment, exemplarily, such as Figure 3 As shown, a support rod 232 extends from the rotating frame 230 toward the wire outlet 220. A tensioning part 233 is disposed on the support rod 232 to tension the wire extending from the wire storage part 231. By placing the tensioning part 233 on the support rod 232, that is, between the tension control device and the wire storage part 231, the wire can contact the tensioning part 233 as it extends toward the tension control device, allowing the tensioning part 233 to tension the wire without needing to pull the wire in other directions, thus making the structure of this embodiment more rational.

[0042] By cooperating with the tensioning part 233 and the tension control device, the tension and winding angle of the wire are kept within a suitable range when the wire is wound onto the wire, thereby ensuring the winding quality of this embodiment.

[0043] In one embodiment, exemplarily, such as Figure 3 As shown, multiple wire storage units 231 are circumferentially distributed on the rotating frame 230, and multiple support rods 232 and tensioning parts 233 are also circumferentially distributed accordingly. The circumferential distribution of multiple wire storage units 231 on the rotating frame 230 ensures the overall structural balance and the efficiency of the winding operation. Simultaneously, multiple support rods 232 and tensioning parts 233 corresponding to the wire storage units 231 are also circumferentially distributed, further enhancing the stability and reliability of the entire winding system. By setting multiple wire storage units 231 and tensioning parts 233, during actual winding operations, the rotating frame 230 begins to rotate, and its rotation drives all wire storage units 231 to rotate synchronously. This allows multiple wires to be guided simultaneously and wound spirally onto the cable, improving not only the precision of the winding process but also significantly increasing the quality and speed of the winding.

[0044] The specific number of the storage line section 231 can be set to two, three, four, five, etc., according to actual needs, and there is no specific limit on the number.

[0045] Please see Figure 4 This embodiment also provides a rigid cable production equipment, including a pulling device, a shaping device, and a winding rotary machine 200 as described in any of the above embodiments. The pulling device pulls the wire sequentially through the winding rotary machine 200 and the shaping device. During the production of rigid cables, the pulling device pulls the glass fiber, causing it to be impregnated with resin and then wound around the resin-laden glass fiber to form a wire. After the wire is formed, it continues to be pulled by the pulling device, moving it to the next winding rotary machine 200, where the winding rotary machine 200 winds and wraps the wire again. After wrapping, the shaping device shapes and dries the wire, thus completing the production of the rigid cable.

[0046] In one embodiment, exemplarily, such as Figure 4 As shown, at least two winding rotary machines 200 are provided, and adjacent winding rotary machines 200 are arranged in opposite directions of rotation. Specifically, when the system starts, the winding assembly of the first winding rotary machine 200 begins to rotate clockwise to perform a preliminary winding operation on the wire. This makes the wire evenly and tightly wound on the wire, forming a preliminary winding layer. The wire continues to move to the next winding rotary machine 200, at which point the winding assembly of the second winding rotary machine 200 rotates counterclockwise to rewind the wire that has already been initially wound. This reverse winding not only further enhances the wrapping density of the wire, but also corrects, to some extent, the minor deviations that may occur during the initial winding, thereby ensuring the uniformity and consistency of the final product.

[0047] When multiple layers of winding are laid on a cable, if these layers are wound in the same direction, the winding force is relatively large because the threads are all wound after tension. Later-wound threads may interfere with earlier-wound layers, affecting the final winding quality of the cable. This opposite-direction arrangement not only helps optimize space utilization but also reduces friction and wear during winding to some extent, and avoids mutual influence or interference between multiple winding layers. Through this alternating and opposite-direction winding method, the cable can achieve multi-layer winding coverage, greatly improving the overall strength, abrasion resistance, and service life of rigid cables, enabling them to consistently meet predetermined technical standards and practical application requirements.

[0048] It should be noted that after the glass fiber is impregnated with resin, it undergoes an initial winding to form a wire. After the wire is formed, any number of winding rotary machines 200 can be set up for further winding as needed, and the material of the wire in each winding rotary machine 200 can also be set individually as needed. In this embodiment, after the wire is formed, at least two winding rotary machines 200 are also provided, and the two winding rotary machines 200 rotate in opposite directions to perform two more layers of winding on the wire, ensuring the production quality of the rigid cable.

[0049] In one embodiment, exemplarily, such as Figure 4 As shown, gaps are provided between adjacent winding rotary machines 200 to observe the winding process of the wire. Thus, the wire, after being wound sequentially, must pass through these gaps to enter the next winding rotary machine 200 for the next winding. Furthermore, a tension control device is provided at the outlet of each winding rotary machine 200. As the wire passes through the tension control device and extends outside the winding rotary machine 200, the wound threads are uniformly and consistently wrapped around the cable.

[0050] By setting a gap between adjacent winding rotary machines 200, operators can clearly see the winding status of the wires on the cable. If any unexpected or defective winding occurs, operators can stop the operation in time to handle it, thus avoiding problems with the final cable quality and improving the stability of the winding quality in this embodiment.

[0051] In one embodiment, for example, the rigid cable production equipment further includes a drive device, which comprises a power component and a transmission component. The power component drives the winding rotary machine 200 to rotate via the transmission component. When it is necessary to control the rotational speed of the winding rotary machine 200, only the power component needs to be controlled. This allows the embodiment to set different rotational speeds, i.e., different wire winding speeds, according to different working conditions, thereby improving the practicality of the embodiment.

[0052] In this embodiment, the power component is a motor, and the transmission components include a driving wheel, a driven wheel, and a transmission chain. The driving wheel is located at the output end of the motor, and the driven wheel is located on the winding assembly of the winding rotary machine 200 to drive the rotating frame 230 of the winding assembly to rotate. The transmission chain is sleeved on the driving wheel and the driven wheel. Thus, when it is necessary to control the winding rotary machine 200 to start winding, the motor is started, the driving wheel rotates, and the driven wheel rotates through the transmission chain, which in turn drives the rotating frame 230 to rotate, thus winding the cable.

[0053] The motor speed is set according to the cable movement speed to match the speed of the two, so that the wires can be wound evenly and stably on the cable during the movement.

[0054] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
