Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of stranding machine technology, and more specifically, to a stranding machine with an adaptive tension adjustment device. Background Technology

[0002] A stranding machine is a mechanical device used to strand multiple monofilaments (such as metal wires, fiber filaments, etc.) into a single cable. It is widely used in industries such as wire and cable, optical fiber cable, steel wire rope, and textile thread. Its core function is to form composite wires with specific structures, strengths, or electrical properties by rotating and stranding the monofilaments.

[0003] In order to ensure the stability and consistency of cable stranding, existing stranding machines require adjustment of cable tension during the stranding process. However, existing tension adjustment devices can only adjust the cable tension when it is too high or too low. Even if the tension can be adjusted afterward, the excessive or insufficient tension has already affected the stability of cable stranding and reduced the efficiency of cable stranding. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a stranding machine with an adaptive tension adjustment device, which solves the technical problem in the prior art that the cable can only be adjusted when the cable tension is too high or too low, which affects the stability of cable stranding and reduces the efficiency of cable stranding.

[0005] According to one aspect, at least one embodiment of this disclosure provides a stranding machine with an adaptive tension adjustment device, including a frame, and further including: wire guide holes, guide wheels, adjusting wheels, support mechanisms, and adjustment mechanisms. Multiple wire guide holes are provided, each on the frame. A guide wheel is rotatably connected to each wire guide hole. Multiple adjusting wheels are provided, each mounted on the frame via a swing mechanism. Each adjusting wheel is opposite to a plurality of wire guide holes. Multiple support mechanisms are provided, each mounted on the frame. Each support mechanism corresponds to multiple swing mechanisms, and each support mechanism is provided with an adjustment mechanism for adjusting the swing mechanisms.

[0006] To support the swinging of the adjusting wheel, the swinging mechanism includes: a swing frame, a fixed frame, a slider, and a detection component. One end of the swing frame is rotatably connected to one side of the frame, and the fixed frame is fixedly connected to the other end of the swing frame. There are two sliders, both of which are slidably connected inside the fixed frame. The two ends of the adjusting wheel are rotatably connected to the two sliders respectively. The detection component is set inside the fixed frame and is used to detect the cable tension.

[0007] In order to detect the pressure on the adjusting wheel in real time, the detection component includes: a base frame, a contact rod, and a pressure detector. The base frame is rotatably connected to the adjusting wheel, the contact rod is fixedly connected to the bottom end of the base frame, the pressure detector is installed in the fixed frame, and the bottom end of the contact rod is in contact with the pressure detector.

[0008] To support the swing frame, the support mechanism includes a support frame and a support rod. One end of the support frame is rotatably connected to the machine frame, the bottom end of the support rod is rotatably connected to the other end of the support frame, and the top end of the support rod is rotatably connected to the swing frame.

[0009] To adjust the swing force of the swing frame, the adjustment mechanism includes: a rotating plate, a sliding rod, a force-bearing block, a support spring, and a pushing assembly. The swing frame and the support frame are both rotatably connected to rotating plates. The sliding rod is slidably connected to a rotating plate near its top. The force-bearing block is fixedly connected to the top of the sliding rod. The support spring is sleeved on the circumferential surface of the sliding rod, and its two ends are fixedly connected to the force-bearing block and the rotating plate, respectively. The pushing assembly is located inside the support frame and is used to drive the force-bearing block and the sliding rod to move.

[0010] In order to move the slide bar and compress the support spring, the pushing assembly includes a first electric cylinder and a push plate. The first electric cylinder is mounted on a rotating plate near the bottom end. The top end of the push plate contacts the bottom end of the force-bearing block. The output end of the first electric cylinder passes through the rotating plate and is fixedly connected to the bottom end of the push plate.

[0011] To increase the stability of the slider during sliding, the fixing frame has two grooves, and the two sliders are slidably connected in the two grooves respectively.

[0012] To increase the stability of the guide wheel during rotation, a rotating seat is fixedly connected to the frame, and the guide wheel is rotatably connected inside the rotating seat.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, by setting up a cable passage hole, a guide wheel, an adjusting wheel, a support mechanism, and an adjustment mechanism, during the cable stranding and conveying process, the cable rests on the adjusting wheel, which enables real-time detection and adjustment of cable tension changes, thereby achieving adaptive adjustment of cable tension, effectively preventing cable stranding instability and improving cable stranding efficiency.

[0022] like Figures 1-4 As shown, a stranding machine with an adaptive tension adjustment device according to an embodiment of this disclosure is illustrated. It includes a frame 1, and further includes: wire passage holes 2, guide wheels 3, adjusting wheels 4, a support mechanism, and an adjustment mechanism. A rotating seat 20 is fixedly connected to the frame 1, and the guide wheels 3 are rotatably connected within the rotating seat 20. Multiple wire passage holes 2 are provided, all of which are opened on the frame 1. Each wire passage hole 2 is rotatably connected to a guide wheel 3. Multiple adjusting wheels 4 are provided, all of which are mounted on the frame 1 via a swing mechanism. Each adjusting wheel 4 is opposite to multiple wire passage holes 2. Multiple support mechanisms are provided, all of which are mounted on the frame 1. Each support mechanism corresponds to multiple swing mechanisms, and each support mechanism is equipped with an adjustment mechanism for adjusting the swing mechanisms. Through the arrangement of the wire passage holes 2, guide wheels 3, adjusting wheels 4, support mechanism, and adjustment mechanism, during the cable stranding and conveying process, the cable rests on the adjusting wheels 4, enabling real-time detection and adjustment of cable tension changes, thereby effectively preventing instability in cable stranding and improving cable stranding efficiency.

[0023] The swing mechanism includes: a swing frame 5, a fixed frame 6, a slider 7, and a detection component. The fixed frame 6 has two grooves 19, and the two sliders 7 are slidably connected in the two grooves 19 respectively. One end of the swing frame 5 is rotatably connected to one side of the frame 1, and the fixed frame 6 is fixedly connected to the other end of the swing frame 5. There are two sliders 7, and both sliders 7 are slidably connected in the fixed frame 6. The two ends of the adjusting wheel 4 are rotatably connected to the two sliders 7 respectively. The detection component is set in the fixed frame 6 and is used to detect the cable tension. The detection component includes: a base frame 8, a contact rod 9, and a pressure detector 10. The base frame 8 is rotatably connected to the adjusting wheel 4, the contact rod 9 is fixedly connected to the bottom end of the base frame 8, and the pressure detector 10 is installed in the fixed frame 6. The bottom end of the contact rod 9 contacts the pressure detector 10. The support mechanism includes: a support frame 11 and a support rod 12. One end of the support frame 11 is rotatably connected to the frame 1, the bottom end of the support rod 12 is rotatably connected to the other end of the support frame 11, and the top end of the support rod 12 is rotatably connected to the swing frame 5.

[0024] During the cable stranding and conveying process, the cable rests on the adjusting wheel 4. When the cable tension changes, the pressure of the cable on the adjusting wheel 4 also changes, causing the two sliders 7 on the adjusting wheel 4 to slide within the fixed frame 6. During the sliding process, the contact force of the contact rod 9 on the pressure detector 10 also changes, thus enabling the pressure detector 10 to detect the tension change in a timely manner.

[0025] The adjustment mechanism includes a rotating plate 13, a sliding rod 14, a force-bearing block 15, a support spring 16, and a pushing assembly. The rotating plate 13 is rotatably connected inside both the swing frame 5 and the support frame 11. The sliding rod 14 is slidably connected to a rotating plate 13 near the top. The force-bearing block 15 is fixedly connected to the top of the sliding rod 14. The support spring 16 is sleeved on the circumferential surface of the sliding rod 14. The two ends of the support spring 16 are fixedly connected to the force-bearing block 15 and the rotating plate 13, respectively. The pushing assembly is set inside the support frame 11 and is used to drive the force-bearing block 15 and the sliding rod 14 to move. The pushing assembly includes a first electric cylinder 17 and a push plate 18. The first electric cylinder 17 is installed on a rotating plate 13 near the bottom. The top of the push plate 18 contacts the bottom of the force-bearing block 15. The output end of the first electric cylinder 17 passes through the rotating plate 13 and is fixedly connected to the bottom of the push plate 18.

[0026] When the pressure detector 10 detects a change in tension, the first electric cylinder 17 receives a command and its output end extends adaptively. During this process, the push plate 18 drives the force block 15 and the slide rod 14 toward the swing frame 5. The support spring 16 is compressed during this process, and then the support stiffness of the support spring 16 is adjusted to adjust the tension of the cable.

[0027] Working principle: During the twisting process, the cable is transported by the rotation of the guide wheel 3 and the adjusting wheel 4. When the cable tension changes, the pressure of the cable on the adjusting wheel 4 also changes, causing the two sliders 7 on the adjusting wheel 4 to slide within the fixed frame 6. During the sliding process, the contact force of the contact rod 9 on the pressure detector 10 also changes, allowing the pressure detector 10 to detect the tension change in a timely manner. When the pressure detector 10 detects the tension change, the output end of the first electric cylinder 17 extends adaptively after receiving the command. During this process, the push plate 18 drives the force block 15 and the slide rod 14 towards the swing frame 5. The support spring 16 is compressed during this process, and then the support stiffness of the support spring 16 is adjusted to regulate the cable tension.

[0028] It should also be noted that when the pressure detector 10 detects a pressure change, a corresponding controller needs to be installed to control the extension and retraction of the first electric cylinder 17.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
