Description

Technical Field

[0001] This invention relates to the field of optical cable manufacturing, and more specifically to a sleeve-stabilized cable laying device. Background Technology

[0002] Optical fiber cables, as the nerve fibers of modern information society, directly determine the quality, bandwidth, and reliability of communication networks. Among the various structures of optical cables, the fiber optic sheath is a key component that houses and protects the bare optical fiber. In core processes such as extrusion and stranding in optical cable production, the control precision and stability of the fiber optic sheath tension are among the core process parameters determining the excess fiber length. Precise excess length control ensures that the optical fiber is in a stress-free state and in an optimal geometric position within the cable core, thereby minimizing micro-bending and macro-bending losses and ensuring that the transmission performance of the final product meets stringent standards. Therefore, the tension control device is a crucial basic equipment in optical cable manufacturing that affects product quality and competitiveness.

[0003] Chinese patent CN221821551U discloses a tension adjusting device for cable production. It uses a brush cleaning mechanism integrated near the tension wheel to clean the cable. However, for applications requiring high tension accuracy during the unwinding process, the brush cleaning mechanism makes the entire tension device more efficient during operation. The introduction of additional and unstable frictional resistance makes it difficult to precisely control the tension during cable laying. Furthermore, the pressure roller uses a spring-loaded clamping method, resulting in limited and unstable positive pressure. During high-tension cable laying, this pressure is insufficient to ensure that there is enough static friction between the cable and the tension roller, which easily leads to slippage. Once slippage occurs, any precise adjustments provided by the tension controller will fail, and the tension actually acting on the cable will become extremely unstable and unpredictable, directly causing uneven fiber length and a decline in product quality. Therefore, it is difficult to meet the stringent requirements for tension accuracy and stability in optical cable manufacturing. Summary of the Invention

[0004] This application provides a casing stabilization and feeding device, which enables precise control of the casing feeding tension, ensures constant tension feeding, and reduces quality defects caused by tension fluctuations.

[0005] In a first aspect, embodiments of this application provide a sleeve stabilizing wire delivery device, comprising: Mounting plate; A damping wheel is provided to provide friction for the movement of the sleeve. The mounting plate is also provided with a resistance adjustment assembly for adjusting the rotational resistance of the damping wheel. The damping wheel is located at the output end of the resistance adjustment assembly. A pressure roller is used to press the sleeve against the surface of the damping wheel. The pressure roller is mounted on the mounting plate and is disposed opposite to the damping wheel. A pressure regulating assembly, which drives the pressure roller to move toward or away from the damping roller to adjust the clamping force on the sleeve, is mounted on the mounting plate.

[0006] In conjunction with the first aspect, in one embodiment, the mounting plate is further provided with a detection component for detecting the speed of the damping wheel and a control component for controlling the drive component.

[0007] In conjunction with the first aspect, in one embodiment, the detection component is a speed sensor, the signal input terminal of the control component is connected to the speed sensor, and the signal output terminal is connected to the pressure regulating component.

[0008] In conjunction with the first aspect, in one embodiment, the resistance adjustment assembly includes a tension controller mounted on a mounting plate, a bracket on the side of the mounting plate away from the damping wheel, the tension controller mounted on the bracket, a coupling at the output end of the tension controller, and the damping wheel mounted at the output end of the coupling.

[0009] In conjunction with the first aspect, in one embodiment, the pressure regulating assembly includes a swing block rotatably mounted on a mounting plate, a pressure roller rotatably mounted on the side of the swing block away from the mounting plate, a fixing block is also provided on the mounting plate, a driving member is provided on the fixing block, and the output end of the driving member abuts against one end of the swing block.

[0010] In conjunction with the first aspect, in one embodiment, the swing block includes an integrally formed rotating part and a pushing part disposed at one corner of the edge of the rotating part and extending outward, wherein the output end of the driving member abuts against the pushing part.

[0011] In conjunction with the first aspect, in one embodiment, the side of the swing block away from the pressure roller is further provided with a first mounting block, the mounting plate is provided with a second mounting block, and a return spring is provided between the first mounting block and the second mounting block.

[0012] In conjunction with the first aspect, in one embodiment, the pressure roller includes two limiting portions and a clamping portion disposed between the two limiting portions, the diameter of the limiting portion being larger than the diameter of the clamping portion, and the limiting portion being used to cooperate with the side of the damping roller to axially limit the sleeve.

[0013] In conjunction with the first aspect, in one embodiment, the mounting plate is further provided with a guide wheel, and a position adjustment component is further provided between the guide wheel and the mounting plate.

[0014] In conjunction with the first aspect, in one embodiment, the position adjustment assembly includes a groove formed on a mounting plate, a slider provided in the groove, a connecting rod extending outward on the slider, a guide wheel rotatably mounted on one end of the connecting rod near the damping wheel, and a locking element provided at the other end of the connecting rod.

[0015] The beneficial effects of the technical solutions provided in this application include: 1. This stabilizing casing feeder replaces the traditional, rudimentary spring-loaded structure with an active pressure adjustment mechanism. This provides a large, stable, and precisely linearly adjustable positive pressure, ensuring that the static friction between the pressure roller and the damping roller is always greater than the tension transmitted by the casing. This fundamentally eliminates slippage, allowing the tension provided by the damping force adjustment mechanism to be completely and reliably transmitted to the casing. Simultaneously, in conjunction with the resistance control of the resistance adjustment component, the tension throughout the entire feeder process becomes precisely controllable, guaranteeing tension stability during casing feeder operation. This significantly reduces the quality risk of uneven excess length caused by tension fluctuations, improving production efficiency and product qualification rate.

[0016] 2. This bushing stabilizing wire feeding device, through the signal connection between the detection component, control component and pressure adjustment component, enables the device to sense the working status of the damping wheel in real time, and when slippage occurs, the control component adjusts the drive component in time to adjust the pressure of the pressure wheel, ensuring that the bushing is not prone to slippage, and further ensuring the tension stability during the wire feeding process.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0021] Please see Figure 1 and Figure 2 This application provides a sleeve stabilizing wire delivery device, comprising: Mounting plate 1 is used to mount the entire wire feeding device; The damping wheel 2 is used to provide friction for the movement of the sleeve. The mounting plate 1 is also provided with a resistance adjustment assembly for adjusting the rotational resistance of the damping wheel 2. The damping wheel 2 is located at the output end of the resistance adjustment assembly. Among them, such as Figure 2 and Figure 3 As shown, the resistance adjustment assembly includes a tension controller 4 mounted on a mounting plate 1. A bracket 17 is provided on the side of the mounting plate 1 away from the damping wheel 2. The tension controller 4 is fixedly mounted on the bracket 17. A coupling 5 is mounted on the output end of the tension controller 4. The damping wheel 2 is mounted on the output end of the coupling 5. Pressure roller 3 is used to press the sleeve onto the wheel surface of damping wheel 2. Pressure roller 3 is mounted on mounting plate 1 and is positioned opposite to damping wheel 2. In this system, the damping wheel 2 and the pressure wheel 3 work together to create an independent auxiliary tension source based on surface friction. This auxiliary tension source works in synergy with the basic tension provided by the pay-off frame, so that the total tension of the system greatly exceeds the limit of the basic tension that the traditional pay-off frame can provide, thus perfectly meeting the high-tension production requirements of special optical fiber products.

[0022] In addition, the auxiliary tension is applied to the outer wall of the sleeve through surface friction, and its force is distributed on the surface of the sleeve, which effectively avoids the direct stress on the internal optical fiber and greatly reduces the risk of optical fiber strain and breakage.

[0023] A pressure regulating component is used to drive the pressure roller 3 to move toward or away from the damping roller 2 to adjust the clamping force on the sleeve. The pressure regulating component is mounted on the mounting plate 1. The pressure regulating component includes a swing block 7 rotatably mounted on the mounting plate 1, a pressure roller 3 rotatably mounted on the side of the swing block 7 away from the mounting plate 1, a fixing block 6 fixedly mounted on the mounting plate 1, a driving component 8 mounted on the fixing block 6, and the output end of the driving component 8 abutting against one end of the swing block 7.

[0024] Specifically, the driving component 8 is either a pneumatic lever or an electric actuator. In this embodiment, it is preferably a pneumatic cylinder. By controlling the extension and retraction of the pneumatic cylinder, the swing block 7 can be driven to deflect. The pressure roller 3 is rotated and mounted on the swing block 7, thereby adjusting the distance between the pressure roller 3 and the damping roller 2, and thus adjusting the pressure of the pressure roller 3 on the surface sleeve of the damping roller 2. This embodiment utilizes an active pressure adjustment mechanism to provide a large, stable, and precisely linearly adjustable positive pressure. This ensures that the static friction between the pressure roller 3 and the damping roller 2 is always greater than the tension transmitted by the bushing, fundamentally eliminating slippage. This allows the tension provided by the damping force adjustment mechanism to be completely and reliably transmitted to the bushing. Simultaneously, in conjunction with the resistance control of the resistance adjustment component, the tension throughout the entire wire feeding process becomes precisely controllable, ensuring tension stability during bushing feeding. This significantly reduces the quality risk of uneven excess length caused by tension fluctuations, improving production efficiency and product qualification rate.

[0025] In this embodiment, the mounting plate 1 is also equipped with a detection component 18 for detecting the speed of the damping wheel 2 and a control component 19 for controlling the drive component 8. The detection component 18 is a speed sensor, and the signal input terminal of the control component 19 is connected to the speed sensor, and the signal output terminal is connected to the pressure regulating component.

[0026] The speed sensor is used to detect the speed, linear speed, or angular speed of the damping wheel 2. During the movement of the sleeve under traction force, based on the physical principle of pure rolling, when there is no relative slippage between the sleeve and the damping wheel 2, the traction linear speed of the sleeve is equal to the rim linear speed of the damping wheel 2. Therefore, the data monitored by the speed sensor directly reflects the friction state between the sleeve and the damping wheel 2. Once the speed sensor detects a deviation between the actual speed of the damping wheel 2 and the traction speed, it indicates that there is a risk of slippage or slippage is occurring. At this time, the speed sensor will transmit the signal to the control component 19, which will adjust the drive component 8 in time and then adjust the pressure of the pressure wheel 3 to ensure that the sleeve is not prone to slippage, and further ensure the tension stability during the wire feeding process.

[0027] In addition, the control component 19 is a PLC controller. As a preferred embodiment, this embodiment uses an S7-1200 series PLC or a compatible model, which can control the drive component 8 based on the set traction speed until the speed of the damping wheel 2 is the same as the traction speed.

[0028] Please see Figure 4 In this embodiment, the swing block 7 includes an integrally formed rotating part 702 and a pushing part 701 disposed at one corner of the edge of the rotating part 702 and extending outward. The output end of the driving member 8 abuts against the pushing part 701.

[0029] Specifically, the driving component 8 deflects the driving push part 701, thereby deflecting the swing block 7 and adjusting the pressure of the sleeve by the pressure roller 3.

[0030] Please see Figure 6 In this embodiment, a first mounting block 11 is fixedly installed on the side of the swing block 7 away from the pressure roller 3, a second mounting block 10 is fixedly installed on the mounting plate 1, and a reset spring 9 is installed between the first mounting block 11 and the second mounting block 10. Among them, by means of the reset spring 9, when the output end of the drive component 8 contracts, the swing block 7 will be reset under the elastic force of the reset spring 9. At this time, the pressure roller 3 will also move away from the damping roller 2, thereby relaxing the pressure on the sleeve.

[0031] Please see Figure 5 The pressure roller 3 includes two limiting parts 302 and a pressing part 301 disposed between the two limiting parts 302. The diameter of the limiting part 302 is larger than the diameter of the pressing part 301.

[0032] The limiting part 302 is used to cooperate with the side of the damping wheel 2 to axially limit the sleeve, thereby making it difficult for the sleeve to detach from the damping wheel 2 during the wire feeding process, thus ensuring the stability of the entire wire feeding process.

[0033] Please see Figure 3 and Figure 7 In this embodiment, a guide wheel 12 is rotatably mounted on the mounting plate 1. A position adjustment component is also provided between the guide wheel 12 and the mounting plate 1. The position adjustment component includes a groove 13 opened on the mounting plate 1. A slider 14 is provided in the groove 13. A connecting rod 15 extending outward is provided on the slider 14. The guide wheel 12 is rotatably mounted on one end of the connecting rod 15 near the damping wheel 2. A locking member 16 is provided at the other end of the connecting rod 15.

[0034] The direction of movement of the sleeve during wire laying can be adjusted by adjusting the position of the guide wheel 12. Specifically, the locking element 16 is preferably a locking nut. The locking element 16 is threadedly connected to the connecting rod 15. Loosening the locking element 16 allows the slider 14 to slide in the slide groove 13. After moving the slider 14 to a suitable position, tightening the locking element 16 completes the fixing of the slider 14, thereby fixing the guide wheel 12 and adjusting the direction of the sleeve wire feeding movement.
