Description
Technical Field
[0001] This utility model relates to the field of tire manufacturing and processing technology, specifically to an adjustable spacing device for attaching conductive cotton threads to tires. Background Technology
[0002] Conductive cotton thread and its auxiliary devices are required in the tire manufacturing process. In order to meet the requirements of tire antistatic and conductive properties, conductive cotton thread needs to be hung at specific work stations in the tire production process. As the core auxiliary equipment of this process, the rationality of the structure of the hanging device directly determines the hanging accuracy of the conductive cotton thread, production efficiency and the final performance of the tire. It is an important part of ensuring the stability of the tire production process.
[0003] In existing technologies, devices for attaching conductive cotton threads to tires are mostly integrated fixed structures. The components supporting the conductive cotton threads cannot be independently adjusted in position. When producing tires of different specifications and requiring changes in the spacing of the conductive cotton threads, the entire attachment device must be replaced. This not only leads to cumbersome operation procedures and increases the time and procurement costs of equipment replacement, but also reduces the flexibility of tire production due to frequent device replacements, thus restricting overall production efficiency. Furthermore, the components in existing devices that thread the conductive cotton threads lack clamping functionality; the conductive cotton threads are simply threaded or placed inside the components. During device operation, vibration, or adjustments, the conductive cotton threads are prone to detaching from the components. This not only compromises the stability of the conductive cotton thread position, causing frequent interruptions in the attachment operation and affecting process reliability, but may also result in substandard tire conductivity due to thread misalignment, negatively impacting tire production quality. Therefore, an adjustable spacing device for attaching conductive cotton threads to tires is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable spacing device for attaching conductive cotton threads to tires. This solves the problem that the components supporting the conductive cotton threads cannot be independently adjusted in position. When producing tires of different specifications and requiring changes in the spacing of the conductive cotton threads, the entire thread-attaching device must be replaced. This not only leads to cumbersome operation procedures and increases the time and procurement costs of equipment replacement, but also reduces the flexibility of tire production due to frequent device replacements, thus restricting overall production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable spacing device for attaching conductive cotton threads to a tire, comprising:
[0006] A conductive cotton coil and a conductive cotton thread wound around the conductive cotton coil, with a conductive opening ring added below the conductive cotton coil, the conductive cotton coil, the conductive cotton thread and the conductive opening ring forming a cotton thread opening device;
[0007] A sliding member is provided below the guide ring, and a support member is provided below the sliding member. A slide rail groove is provided below the support member. The sliding member, the slide rail groove and the support member form a cotton thread spacing adjustment device. An elastic clip is provided in the inner cavity of the sliding member.
[0008] Place the conductive cotton coil with the conductive cotton thread wound around it in the preset working area and ensure that the conductive cotton coil is in a stable state. Then, pull the free end of the conductive cotton thread to the opening ring below the conductive cotton coil so that the conductive cotton thread passes through the inner cavity of the opening ring. The opening ring constrains and guides the lead-out path of the conductive cotton thread. At this time, the cotton thread opening device composed of the conductive cotton coil, the conductive cotton thread and the opening ring completes the initial opening and positioning of the conductive cotton thread.
[0009] Continue to pull the free end of the conductive cotton thread that has passed through the open ring to the sliding part below the open ring. Open the elastic clip inside the sliding part and put the free end of the conductive cotton thread into the clamping area of the elastic clip. Loosen the elastic clip and use the elastic force of the elastic clip to clamp and fix the conductive cotton thread to prevent the conductive cotton thread from loosening or shifting during subsequent adjustment.
[0010] According to the actual spacing requirements of the conductive cotton thread hanging on the tire, an external force is applied to the sliding component to push it to slide along the slide rail groove above the support component. During this process, the support component provides vertical stability support for the sliding component, preventing it from tilting or deviating during sliding and ensuring that the sliding component moves smoothly along the preset trajectory of the slide rail groove.
[0011] When the sliding member moves the conductive cotton thread to a position that meets the tire cable spacing requirements, the external force applied to the sliding member stops; the elastic clips continue to clamp the conductive cotton thread, and the sliding member maintains its current position in the slide rail groove. At this time, the cotton thread spacing adjustment device composed of the sliding member, slide rail groove and support member completes the spacing locking, and the conductive cotton thread adapts to the tire cable hanging operation with the required spacing.
[0012] Preferably, a flexible buffer layer is added to the inner surface of the elastic clip, and a limiting protrusion array is installed on the surface of the flexible buffer layer, the limiting protrusion array including hemispherical protrusions. The adaptive deformation characteristics of the flexible buffer layer can prevent the elastic clip from damaging conductive cotton threads of different diameters, while increasing the contact friction with the conductive cotton threads, effectively solving the problems of loose clamping of thin-diameter conductive cotton threads and damage to thick-diameter conductive cotton threads; the hemispherical protrusions of the limiting protrusion array are embedded in the gaps between the conductive cotton thread fibers, which can effectively limit the axial sliding of the conductive cotton threads in high-speed rotation or equipment vibration environments, significantly improving clamping stability and improving the problem of decreased clamping stability caused by uneven deformation of the elastic clip after long-term use; this improved structure does not change the core clamping function and structural form of the original elastic clip, can be adapted to the assembly requirements of the original device, does not require additional adjustment of the overall structure of the device, and reduces modification costs.
[0013] Preferably, limit plates are installed on both sides of the back of the slider, and guide grooves are provided at the front and rear ends of the outer side of the limit plates. The limit plates on both sides of the back of the slider can longitudinally limit the movement range of the slider, preventing the slider from disengaging from the mating area of the slide rail groove during movement and improving movement safety; the guide grooves at the front and rear ends of the outer side of the limit plates can provide initial guidance for the movement of the slider, reduce the lateral deviation of the slider during movement, lay the foundation for subsequent high-precision mating with the slide rail groove, and alleviate the problem of insufficient guidance accuracy when the original slider moves; the limit plates and the slider adopt an integrated installation design, without adding additional assembly steps, and have high structural strength, which can withstand the force of the slider during movement for a long time, avoiding the impact of movement accuracy due to structural deformation and ensuring long-term stability.
[0014] Preferably, a limiting groove is formed at the center of the upper surface of the slide rail groove, and guide ribs are installed on the upper and lower parts of both sides of the inner wall of the limiting groove. The limiting groove at the center of the upper surface of the slide rail groove can effectively wrap around the limiting plate of the sliding component, further restricting the lateral displacement of the sliding component, improving the stability of the cooperation between the sliding component and the slide rail groove, and improving the loose fit problem caused by the original slide rail groove being only an "embedded support rail"; the guide ribs on the upper and lower parts of both sides of the inner wall of the limiting groove can cooperate with the guide groove of the limiting plate from multiple directions, significantly improving the guiding accuracy of the sliding component's movement, especially in the scenario of small-pitch fine adjustment, which can reduce adjustment deviation and solve the problem of "movement jamming and pitch adjustment deviation" caused by the low guiding accuracy of the original slide rail groove; the guide ribs and the limiting groove adopt an integrated design, with strong structural stability, and are not easy to fall off or deform due to long-term use, ensuring the long-term effectiveness of the guiding function and eliminating the need for frequent maintenance and replacement.
[0015] Preferably, the limiting groove and guide rib are slidably fitted with the limiting plate and guide groove, respectively, and the inner wall of the limiting groove and the surface of the guide rib are coated with a tungsten carbide wear-resistant coating. The sliding fit between the limiting groove and the limiting plate, and between the guide rib and the guide groove, can control the lateral offset of the sliding component during movement to a very small range, significantly improving the spacing adjustment accuracy, meeting the needs of fine-tuning small spacing, and solving the pain point of low guiding accuracy of the original slide rail groove; the tungsten carbide wear-resistant coating on the inner wall of the limiting groove and the surface of the guide rib can effectively resist frictional wear, greatly extend the service life of the limiting groove and the guide rib, thereby improving the overall service life of the entire device, alleviating the problem of the original slide rail groove's inner wall wear caused by long-term friction and shortening the device's lifespan; the low friction characteristics of the tungsten carbide wear-resistant coating can reduce the resistance when the sliding component moves, making the sliding component move more smoothly, reducing the noise during equipment operation, and at the same time reducing structural wear caused by friction, thus reducing equipment maintenance costs.
[0016] Preferably, a bracket is added between the guide ring and the sliding member, and a guide wheel is rotatably connected to the lower surface of the bracket. A guide ring groove is formed at the center of the guide wheel, and the guide ring groove corresponds to the position of the conductive cotton thread. The guide wheel has an overall I-shaped design. The addition of the bracket and guide wheel fills the guiding gap between the guide ring and the sliding member, preventing the conductive cotton thread from drifting laterally in this section due to high-speed feeding or equipment vibration. This ensures that the conductive cotton thread accurately enters the clamping hole of the sliding member, reduces frequent manual adjustments, ensures production continuity, and solves the problem of missing cotton thread guidance in this section in the original technology. The guide ring groove at the center of the guide wheel corresponds to the position of the conductive cotton thread, enabling precise positioning of the conductive cotton thread. The rotational characteristics of the guide wheel can convert the sliding friction between the two into rolling friction, greatly reducing frictional loss with the conductive cotton thread, avoiding the decrease in conductivity caused by thread wear, and ensuring the performance of the conductive cotton thread. The I-shaped design of the guide wheel can restrict the displacement of the conductive cotton thread from the vertical direction, further improving guiding stability.
[0017] Compared with the prior art, this utility model provides an adjustable spacing device for attaching conductive cotton threads to tires, which has the following beneficial effects:
[0018] This adjustable spacing device for attaching conductive cotton threads to tires consists of a sliding member, a slide rail groove, and a support member. The sliding member is located below the guide ring, the support member is located below the sliding member, and the slide rail groove is located below the support member. By moving the sliding member in conjunction with the slide rail groove, the position of the conductive cotton thread passing through the sliding member can be changed, thereby adjusting the spacing between the conductive cotton threads. Unlike existing technologies, it eliminates the need to replace the entire thread attachment device, thus meeting the different spacing requirements of conductive cotton threads for tires of different specifications. This simplifies the operation process, reduces the cost incurred by replacing the device, and improves the flexibility and efficiency of tire production.
[0019] The inner cavity of the sliding component is equipped with an elastic clip, which can clamp the conductive cotton thread passing through the sliding component, effectively preventing the conductive cotton thread from falling out of the sliding component during the movement of the sliding component or the operation of the device, ensuring the stability of the conductive cotton thread position, further ensuring the reliability of the tire-attached conductive cotton thread operation, and ensuring the tire production quality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a technical solution: an adjustable spacing device for attaching conductive cotton threads to a tire, comprising: (see details) Figures 1 to 6 A conductive cotton coil 1 and a conductive cotton thread 2 wound on the conductive cotton coil 1, and a conductive opening ring 3 is provided below the conductive cotton coil 1. The conductive cotton coil 1, the conductive cotton thread 2 and the conductive opening ring 3 constitute a cotton thread opening device.
[0029] The sliding member 4 is located below the guide ring 3, and a support member 6 is added below the sliding member 4. A slide rail groove 5 is provided below the support member 6. The sliding member 4, the slide rail groove 5 and the support member 6 form a cotton thread spacing adjustment device. An elastic clip 8 is added to the inner cavity of the sliding member 4.
[0030] Place the conductive cotton coil 1, which is wrapped with conductive cotton thread 2, in the preset working area and ensure that the conductive cotton coil 1 is in a stable state; then pull the free end of the conductive cotton thread 2 to the open ring 3 below the conductive cotton coil 1, so that the conductive cotton thread 2 passes through the inner cavity of the open ring 3. The open ring 3 constrains and guides the lead-out path of the conductive cotton thread 2. At this time, the cotton thread opening device composed of the conductive cotton coil 1, the conductive cotton thread 2 and the open ring 3 completes the initial opening and positioning of the conductive cotton thread 2.
[0031] Continue to pull the free end of the conductive cotton thread 2 that has passed through the open ring 3 to the sliding member 4 below the open ring 3. Open the elastic clip 8 inside the sliding member 4, put the free end of the conductive cotton thread 2 into the clamping area of the elastic clip 8, loosen the elastic clip 8, and use the elastic force of the elastic clip 8 to clamp and fix the conductive cotton thread 2 to prevent the conductive cotton thread 2 from loosening or shifting during subsequent adjustment.
[0032] According to the actual spacing requirements of the conductive cotton thread 2 hanging on the tire, an external force is applied to the sliding member 4 to push the sliding member 4 to slide along the slide rail groove 5 above the support member 6; during this process, the support member 6 provides vertical stability support for the sliding member 4, preventing the sliding member 4 from tilting or deviating during sliding, and ensuring that the sliding member 4 moves smoothly along the preset trajectory of the slide rail groove 5.
[0033] When the slider 4 moves the conductive cotton thread 2 to a position that meets the tire cord spacing requirements, the external force applied to the slider 4 stops; the elastic clamp 8 continues to clamp the conductive cotton thread 2, and the slider 4 maintains its current position in the slide rail groove 5. At this time, the cotton thread spacing adjustment device composed of the slider 4, the slide rail groove 5 and the support 6 completes the spacing locking, and the conductive cotton thread 2 adapts to the tire cord cording operation with the required spacing.
[0034] The cotton thread guiding device, consisting of a conductive cotton coil 1, a conductive cotton thread 2, and a guiding ring 3, provides a stable winding carrier for the conductive cotton thread 2. The guiding ring 3 can accurately guide the output direction of the conductive cotton thread 2, effectively avoiding the problems of tangling, knotting, or output path deviation of the conductive cotton thread 2 during the guiding process. This ensures that the conductive cotton thread 2 is always conveyed to the subsequent adjustment stage in an orderly manner, improving the reliability of cotton thread pretreatment before tire cord attachment.
[0035] The cotton thread spacing adjustment device, composed of the sliding member 4, the slide rail groove 5, and the support member 6, dynamically adjusts the spacing of the conductive cotton thread 2 by sliding the sliding member 4 along the slide rail groove 5. It can adapt to tires of different specifications and different thread hanging requirements, greatly improving the versatility of the device. The elastic clamp 8 inside the sliding member 4 can reliably clamp the conductive cotton thread 2, which not only avoids the spacing deviation caused by the loosening of the cotton thread during the adjustment process, but also keeps the cotton thread position stable after the adjustment is completed, ensuring the accuracy of the spacing of the conductive cotton thread 2 when the tire is attached.
[0036] The device consists of two main modules: a cotton thread opening device and a cotton thread spacing adjustment device. The conductive cotton coil 1, conductive cotton thread 2, opening ring 3, sliding component 4, slide rail groove 5, support component 6, and elastic clamp 8 have clearly defined functions and no complex transmission or control structure. Operators can complete operations such as opening, clamping, and spacing adjustment of the cotton thread without professional skills, which lowers the threshold for use. At the same time, the connection between the components is simple, which facilitates later maintenance and replacement and extends the overall service life of the device.
[0037] Please see Figure 2 and Figure 3 A flexible buffer layer 9 is added to the inner side of the elastic clip 8, and a limiting protrusion array 10 is installed on the surface of the flexible buffer layer 9, the limiting protrusion array 10 including hemispherical protrusions. When the conductive cotton thread 2 enters the clamping area of the elastic clip 8, the elastic clip 8 generates clamping force by its own elasticity. At this time, the flexible buffer layer 9 on the inner side of the elastic clip 8 will adaptively deform according to the actual wire diameter of the conductive cotton thread 2, tightly fitting the outer surface of the conductive cotton thread 2 to adapt to conductive cotton threads 2 of different wire diameters; at the same time, the limiting protrusion array 10 installed on the surface of the flexible buffer layer 9 will embed into the fiber gaps of the conductive cotton thread 2, forming a mechanical limiting effect. As the clamping force of the elastic clip 8 continues to act, the contact area between the flexible buffer layer 9 and the conductive cotton thread 2 further increases, and the embedding depth of the hemispherical protrusions and the fiber gaps remains stable, ensuring that the conductive cotton thread 2 does not undergo relative displacement in the clamped state; the flexible buffer layer 9 The adaptive deformation characteristics prevent the elastic clamp 8 from damaging conductive cotton threads 2 of different diameters, while increasing the contact friction with the conductive cotton threads 2, effectively solving the problems of loose clamping of thin-diameter conductive cotton threads 2 and damage to thick-diameter conductive cotton threads 2; the hemispherical protrusions of the limiting protrusion array 10 are embedded in the fiber gaps of the conductive cotton threads 2, which can effectively limit the axial sliding of the conductive cotton threads 2 in high-speed rotation or equipment vibration environment, significantly improving clamping stability and improving the problem of decreased clamping stability caused by uneven deformation of the elastic clamp 8 after long-term use; this improved structure does not change the core clamping function and structural form of the original elastic clamp 8, can be adapted to the assembly requirements of the original device, and does not require additional adjustment of the overall structure of the device, reducing the modification cost.
[0038] Limiting plates 11 are installed on both sides of the back of the sliding member 4, and guide grooves 12 are provided at the front and rear ends of the outer side of the limiting plates 11. When the sliding member 4 needs to move along the slide rail groove 5 to adjust the spacing, the limiting plates 11 installed on both sides of the back of the sliding member 4 will move synchronously with the movement of the sliding member 4. First, the limiting plates 11 enter the corresponding mating area of the slide rail groove 5. At this time, the guide grooves 12 at the front and rear ends of the outer side of the limiting plates 11 will be pre-aligned with the subsequent guide ribs 14 of the relevant structure on the slide rail groove 5. During the continuous movement of the sliding member 4, the guide grooves 12 always maintain a close fit with the corresponding structure, which initially limits the movement direction of the sliding member 4. At the same time, the structure of the limiting plates 11 itself can prevent the sliding member 4 from moving up and down during movement, ensuring that the sliding member 4 moves smoothly along the length direction of the slide rail groove 5. The limiting plates 11 on both sides of the back of the sliding member 4 can longitudinally limit the movement range of the sliding member 4. To prevent the sliding component 4 from disengaging from the sliding rail groove 5 during movement, thus improving movement safety; the guide grooves 12 at the front and rear ends of the outer side of the limiting plate 11 provide initial guidance for the movement of the sliding component 4, reducing lateral deviation during movement and laying the foundation for subsequent high-precision engagement with the sliding rail groove 5, alleviating the problem of insufficient guidance accuracy during the movement of the original sliding component 4; the limiting plate 11 and the sliding component 4 adopt an integrated installation design, without adding extra assembly steps, and have high structural strength, which can withstand the force of the sliding component 4 during movement for a long time, avoiding the impact of structural deformation on movement accuracy and ensuring long-term stability.
[0039] Please see Figure 4 and Figure 5A limiting groove 13 is formed at the center of the upper surface of the slide rail groove 5, and guide ribs 14 are installed on the upper and lower parts of both sides of the inner wall of the limiting groove 13. When the sliding member 4 is assembled with the slide rail groove 5, the limiting plate 11 on the back of the sliding member 4 will be embedded into the limiting groove 13 formed at the center of the upper surface of the slide rail groove 5. The inner wall of the limiting groove 13 forms a left-right constraint on the limiting plate 11, restricting the lateral displacement of the sliding member 4. At the same time, the guide ribs 14 installed on the upper and lower parts of both sides of the inner wall of the limiting groove 13 will form a corresponding fitting relationship with the guide groove 12 on the outer side of the limiting plate 11. When the slider 4 moves along the slide rail groove 5, the guide rib 14 always slides within the guide groove 12. Through the close contact between the guide rib 14 and the guide groove 12, the movement trajectory of the slider 4 is precisely limited, ensuring that the slider 4 moves only along the length direction of the limiting groove 13 without deviation or jamming. The limiting groove 13 at the center of the upper surface of the slide rail groove 5 can effectively wrap around the limiting plate 11 of the slider 4, further restricting the lateral displacement of the slider 4, improving the stability of the cooperation between the slider 4 and the slide rail groove 5, and improving the original slide rail groove 5, which is only a "track for embedding support". The guide ribs 14 on the upper and lower parts of the inner wall of the limiting groove 13 can cooperate with the guide grooves 12 of the limiting plate 11 from multiple directions, significantly improving the guiding accuracy of the sliding part 4. Especially in the case of fine adjustment of small gap, it can reduce the adjustment deviation and solve the problem of "movement jamming and gap adjustment deviation" caused by the low guiding accuracy of the original slide rail groove 5. The guide ribs 14 and the limiting groove 13 adopt an integrated design, which has strong structural stability and is not easy to fall off or deform due to long-term use, ensuring the long-term effectiveness of the guiding function and eliminating the need for frequent maintenance and replacement.
[0040] The limiting groove 13 and the guide rib 14 are slidably fitted with the limiting plate 11 and the guide groove 12, respectively, and the inner wall of the limiting groove 13 and the surface of the guide rib 14 are coated with a tungsten carbide wear-resistant coating. During the movement of the sliding member 4, the inner wall of the limiting groove 13 and the limiting plate 11 remain in a slidably fitted state, and the guide rib 14 and the guide groove 12 also remain in a slidably fitted state. Through the double fitting and cooperation of the two, a double guiding constraint is formed to ensure that the sliding member 4 moves smoothly along the preset trajectory and avoids deviation. At the same time, the inner wall of the limiting groove 13 and the surface of the guide rib 14 are coated with a tungsten carbide wear-resistant coating, which directly rubs against the contact surfaces of the limiting plate 11 and the guide groove 12. Because of its high hardness, the tungsten carbide wear-resistant coating is not prone to wear during friction and can reduce the coefficient of friction with the contact surface, making the movement of the sliding part 4 smoother and avoiding jamming. The sliding fit between the limiting groove 13 and the limiting plate 11, and between the guide rib 14 and the guide groove 12, can control the lateral offset of the sliding part 4 to a very small range, significantly improving the spacing adjustment accuracy, meeting the needs of fine-tuning small spacing, and solving the problem of low guiding accuracy of the original slide rail groove 5. The tungsten carbide wear-resistant coating on the inner wall of the limiting groove 13 and the surface of the guide rib 14 can effectively resist frictional wear, greatly extending the service life of the limiting groove 13 and the guide rib 14, thereby improving the overall service life of the entire device and alleviating the problem of the original slide rail groove 5 being worn on the inner wall due to long-term friction, which shortens the life of the device. The low friction characteristics of the tungsten carbide wear-resistant coating can reduce the resistance when the sliding part 4 moves, making the sliding part 4 move more smoothly, reducing the noise during equipment operation, and reducing structural wear caused by friction, thus reducing equipment maintenance costs.
[0041] Please see Figure 6A bracket 7 is provided between the guide ring 3 and the sliding member 4, and a guide wheel 15 is rotatably connected to the lower surface of the bracket 7. A guide ring groove 16 is provided in the center of the guide wheel 15, and the guide ring groove 16 corresponds to the position of the conductive cotton thread 2. The guide wheel 15 has an overall I-shaped design. After being guided by the guide ring 3, the conductive cotton thread 2 will enter the area below the bracket 7 provided between the guide ring 3 and the sliding member 4. Because the lower surface of the bracket 7 is rotatably connected to the guide wheel 15, and the guide ring groove 16 opened in the center of the guide wheel 15 corresponds to the position of the conductive cotton thread 2, the conductive cotton thread 2 will be precisely embedded in the guide ring groove 16. During the continuous feeding of the conductive cotton thread 2, the guide wheel 15 will rotate synchronously with the movement of the conductive cotton thread 2, and the guide ring groove 16 will form a lateral constraint on the conductive cotton thread 2 to prevent the conductive cotton thread 2 from drifting laterally. At the same time, the guide wheel 15 has an overall I-shaped design, which can further limit the displacement of the conductive cotton thread 2 from the vertical direction, ensuring that the conductive cotton thread 2 is always accurately fed to the clamping area of the sliding member 4 along the preset path. The addition of the bracket 7 and the guide wheel 15 fills the guide gap between the guide ring 3 and the sliding member 4, preventing the conductive cotton thread 2 from drifting laterally in this section due to high-speed feeding or equipment vibration, and ensuring the conductive cotton thread 2. The guide wheel 15 is precisely inserted into the clamping hole of the sliding component 4, reducing frequent manual adjustments, ensuring production continuity, and solving the problem of missing cotton thread guidance in this section in the original technology; the guide ring groove 16 at the center of the guide wheel 15 corresponds to the position of the conductive cotton thread 2, which can accurately position the conductive cotton thread 2, and the rotational characteristics of the guide wheel 15 can convert the sliding friction between the two into rolling friction, greatly reducing friction loss with the conductive cotton thread 2, avoiding the decrease in conductivity caused by thread wear, and ensuring the performance of the conductive cotton thread 2; the I-shaped design of the guide wheel 15 can restrict the displacement of the conductive cotton thread 2 from the top and bottom, further improving the guiding stability; and the installation of the bracket 7 does not change the original structure and assembly relationship of the guide ring 3 and the sliding component 4, adapting to the layout requirements of the original device, without the need for large-scale modification of the overall structure of the device, reducing improvement costs.
[0042] This solution involves placing a conductive cotton coil 1, wrapped with conductive cotton thread 2, in a preset working area to ensure that the conductive cotton coil 1 is in a stable state. Then, the free end of the conductive cotton thread 2 is pulled to the open ring 3 below the conductive cotton coil 1, so that the conductive cotton thread 2 passes through the inner cavity of the open ring 3. The conductive cotton thread 2 is then pulled to the support 7 added between the open ring 3 and the sliding member 4, so that the conductive cotton thread 2 is embedded in the guide ring groove 16 opened in the center of the guide wheel 15 rotatably connected to the lower surface of the support 7. The guide wheel 15 rotates synchronously with the movement of the conductive cotton thread 2, and the guide ring groove 16 forms a lateral constraint on the conductive cotton thread 2. The I-shaped design of the guide wheel 15 restricts the displacement of the conductive cotton thread 2 from the vertical direction.
[0043] Next, the free end of the conductive cotton thread 2 passing through the guide ring groove 16 is further pulled to the sliding member 4 below the guide ring 3. The elastic clip 8 inside the sliding member 4 is opened, and the free end of the conductive cotton thread 2 is placed into the clamping area of the elastic clip 8. The elastic clip 8 is released, and the elastic clip 8 generates clamping force by its own elasticity. The flexible buffer layer 9 on the inner side of the elastic clip 8 adapts to the actual wire diameter of the conductive cotton thread 2 and fits tightly against the outer surface of the conductive cotton thread 2. The limiting protrusion array 10 on the surface of the flexible buffer layer 9 is embedded in the fiber gap of the conductive cotton thread 2 to form mechanical limiting.
[0044] According to the actual spacing requirements of the conductive cotton line 2 for the tire, an external force is applied to the sliding member 4, pushing the sliding member 4 to move along the slide rail groove 5 above the support member 6. The limiting plates 11 installed on both sides of the back of the sliding member 4 simultaneously enter the limiting groove 13 opened in the center of the upper surface of the slide rail groove 5. The inner wall of the limiting groove 13 forms a left-right constraint on the limiting plate 11. The guide grooves 12 opened at the front and rear ends of the outer side of the limiting plate 11 and the guide ribs 14 installed on the upper and lower parts of the inner wall of the limiting groove 13 form a corresponding interlocking and close fit. The tungsten carbide wear-resistant coating sprayed on the inner wall of the limiting groove 13 and the surface of the guide ribs 14 reduces the friction coefficient of the contact surface with the limiting plate 11 and the guide groove 12. When the sliding member 4 moves the conductive cotton line 2 to a position that meets the tire hanging line spacing requirements, the external force applied to the sliding member 4 is stopped. The elastic clamp 8 continues to clamp the conductive cotton line 2. The sliding member 4 maintains its current position in the slide rail groove 5, and the conductive cotton line 2 adapts to the tire hanging line operation with the required spacing.
