Description

Technical Field

[0001] This application relates to the field of tire production equipment technology, and in particular to a control device for adjusting tire sidewall synchronization and equal length. Background Technology

[0002] With the booming development of the automotive industry, the requirements for tire quality and performance are increasing. The production process for tire components is constantly being optimized and upgraded to improve production efficiency and product quality. As a crucial component of the tire, the sidewall's production quality directly affects the tire's overall performance and safety.

[0003] In tire sidewall production, the sidewall needs to be rolled and stretched to meet usage requirements. Currently, the sidewall is typically formed by rolling a single long shaft, applying uniform pressure through the long shaft.

[0004] However, when using a single long-axis roller to press the tire sidewall, due to the special triangular cross-section shape of the sidewall, the two sidewalls may shift and wobble laterally during the pressing process, resulting in inconsistent stretching between the two sidewalls. This not only poses quality risks at the curling station and subsequent molding processes but also wastes materials and fails to achieve the desired performance.

[0005] The aforementioned technologies suffer from a defect of poor tension consistency between the two tire sides. Utility Model Content

[0006] To improve the problem of poor tension consistency between the two tire sidewalls, this application provides a control device for adjusting the synchronous equal length of the tire sidewalls.

[0007] The tire sidewall synchronization and equal length control device provided in this application adopts the following technical solution: A device for adjusting tire sidewall synchronization and equal length control includes: a support mechanism, the support mechanism including a support frame and a support assembly, the support assembly being connected to the support frame; a rolling mechanism, the rolling mechanism including a connecting frame and two sets of rolling rollers, one end of the connecting frame being connected to the support assembly, the rolling rollers being rotatably connected to the other end of the connecting frame, the two sets of rolling rollers being distributed along their own axial direction, the rolling rollers being used to roll the tire sidewall, the rolling rollers corresponding one-to-one with the tire sidewall, and the cross-section of the rolling rollers extending along the axial direction being spindle-shaped; and a spacing adjustment mechanism, the spacing adjustment mechanism being connected to the connecting frame, the spacing adjustment mechanism being used to adjust the spacing between the two sets of rolling rollers.

[0008] By adopting the above technical solution, the support frame of the support mechanism provides a support foundation for the entire device, and the support components connect to the support frame, playing a role in stabilization and auxiliary support; the connecting frame of the roller pressing mechanism connects the roller pressing rollers to the support components, and the shuttle-shaped roller pressing rollers can better adapt to the shape of the tire sidewall, keeping the tire sidewall stable during the rolling process and reducing the risk of deviation and swaying; the moving conveyor of the tire sidewall can drive the roller pressing rollers rotatably connected to the connecting frame to achieve rolling, and the two sets of roller pressing rollers correspond one-to-one with the two tire sidewalls to ensure that the two tire sidewalls are effectively rolled, while improving the stability of the tire sidewalls to ensure that the two are rolled simultaneously. The length of the tire sidewalls remains consistent. Due to the different positions of the feed belt centers of tire sidewalls with different widths, the spacing between the two tire sidewalls changes. The spacing adjustment mechanism is connected to the connecting frame and can adjust the spacing between the two sets of rollers, so that the device can adapt to tire sidewalls of different widths. This ensures that the two tire sidewalls can be processed more accurately during the rolling process, and that the two tire sidewalls always maintain the same length when rolling. This avoids the quality problems and material waste caused by inconsistent tire sidewall stretching in the existing technology, which are caused by uneven stretching of the tire sidewalls at the rolling station and subsequent forming processes. At the same time, the structure is simple, the operation is convenient, and it can be applied to different tire specifications.

[0009] Optionally, the support assembly includes two sets of support members, one end of which is connected to the support frame and the other end of which is connected to the rolling mechanism. The two sets of support members are located on opposite sides of the support frame.

[0010] By adopting the above technical solution, two sets of support components are set on opposite sides of the support frame, which can stably connect the support frame and the rolling mechanism, provide a stable support foundation for the rolling mechanism, ensure the structural stability of the entire device during operation, and enable the rolling mechanism to perform rolling operation on the tire sidewall normally and accurately.

[0011] Optionally, the connecting frame includes a connecting shaft, a roller shaft, and two sets of connecting parts. The two ends of the connecting shaft are rotatably connected to the two supporting parts, and the two sets of connecting parts are spaced apart. The first end of the connecting part is connected to the connecting shaft, and the two ends of the roller shaft are respectively connected to the second ends of the two sets of connecting parts. Both sets of rollers are rotatably connected to the roller shaft.

[0012] By adopting the above technical solution, the connecting shaft rotatably connects two support members, enabling the connecting frame to be stably connected to the support mechanism and achieving a certain degree of rotational flexibility; the two sets of spaced connecting members, with their first end connected to the connecting shaft and the second end connected to the roller pressing shaft, serve to connect and fix the connecting shaft and the roller pressing shaft, ensuring the stability of the structure; while the roller pressing shaft provides rotational support for the two sets of roller pressing wheels, enabling the roller pressing wheels to rotate stably and roll the tire sidewall, ensuring the normal operation of the entire tire sidewall synchronous equal length control device.

[0013] Optionally, the roller pressing mechanism includes two sets of connecting components, each corresponding to one of the roller pressing wheels. Each connecting component includes two sets of bearings and two sets of connecting sleeves. The two sets of bearings are respectively located at both ends of the roller pressing wheel, and the two sets of connecting sleeves are respectively located at both ends of the roller pressing wheel. The connecting sleeves are sleeved on the roller pressing shaft and are slidably connected to the roller pressing shaft. The bearings are sleeved on the outer periphery of the first end of the connecting sleeves, and the end of the roller pressing wheel is sleeved on the outer periphery of the bearings, so that the roller pressing wheel can rotate relative to the roller pressing shaft.

[0014] By adopting the above technical solution, the connecting components correspond one-to-one with the rollers. Two sets of bearings for each connecting component are respectively located at both ends of the roller, effectively reducing frictional resistance during roller rotation and ensuring smooth rotation. Two sets of connecting sleeves are also respectively located at both ends of the roller, fitted onto and slidably connected to the roller shaft, allowing the roller to slide along the shaft and facilitating adjustment of its position according to actual needs. Simultaneously, the bearings are fitted around the outer circumference of the first end of the connecting sleeve, and the roller end is fitted around the outer circumference of the bearings. This structure further ensures that the roller can rotate flexibly relative to the roller shaft, thereby enabling more precise roller pressing of the tire sidewall and improving the quality and efficiency of sidewall pressing.

[0015] Optionally, the spacing adjustment mechanism includes a spacing adjustment screw and two sets of moving components. The two ends of the spacing adjustment screw are rotatably connected to the two sets of connecting members. The spacing adjustment screw is parallel to and spaced apart from the roller shaft. The moving components correspond one-to-one with the rollers. The first end of the moving component is screwed to the spacing adjustment screw, and the second end of the moving component is slidably connected to the roller shaft. The second end of the moving component is connected to a connecting sleeve corresponding to the roller.

[0016] By adopting the above technical solution, two sets of connecting parts are rotatably connected to both ends of the pitch adjustment screw, which are parallel to and spaced apart from the roller shaft, providing a track and power transmission path for the two sets of moving components. Each moving component corresponds to a roller. Its first end is screwed to the pitch adjustment screw, and using the screw drive principle, when the pitch adjustment screw rotates, it drives the moving component to move along the screw axis. The second end is slidably connected to the roller shaft, ensuring the stability and guidance of the moving component's movement. Simultaneously, the second end of the moving component is connected to a connecting sleeve of the corresponding roller, thereby driving the roller to move and achieving the purpose of adjusting the pitch between the two sets of rollers. This adapts to the production needs of tire sidewalls of different specifications, improving the applicability of the device.

[0017] Optionally, the pitch adjusting screw is a bidirectional screw, so that when the bidirectional screw rotates, the two sets of moving components move in opposite directions.

[0018] By adopting the above technical solution, the spacing adjustment screw is set as a bidirectional screw. When the bidirectional screw rotates, since the two sets of moving components are screwed to different helical parts of the bidirectional screw, the two sets of moving components will move in opposite directions. This design can adjust the spacing of the two sets of rollers simultaneously. During the tire sidewall production process, the spacing between the two sets of rollers can be easily and precisely adjusted according to different tire specifications or actual production needs, ensuring that the rollers better fit the tire sidewall and roll it, thereby effectively avoiding the problems caused by tire sidewall misalignment and wobbling in the existing technology, and ensuring that the two tire sidewalls always maintain the same length when rolled.

[0019] Optionally, the spacing adjustment mechanism includes a rotary handle connected to the spacing adjustment screw, and the rotary handle is used to drive the spacing adjustment screw to rotate.

[0020] By adopting the above technical solution, the rotary handle is connected to the spacing adjustment screw. Rotating the rotary handle can drive the spacing adjustment screw to rotate. Since the two ends of the spacing adjustment screw are rotatably connected to two sets of connecting parts, and a moving component is screwed on it, and the moving component is slidably connected to the roller, the rotation of the spacing adjustment screw can adjust the spacing between the two sets of rollers, thereby adapting to tire sidewalls of different widths, ensuring effective rolling of tire sidewalls of different specifications, and making the device more applicable.

[0021] Optionally, the moving component includes an internal threaded sleeve and a moving part, the internal threaded sleeve being screwed onto the pitch adjusting screw, one end of the moving part being connected to the internal threaded sleeve, and the other end of the moving part being connected to the second end of the connecting sleeve.

[0022] By adopting the above technical solution, the internal threaded sleeve is screwed to the lead screw, which can convert the rotational motion of the lead screw into its own linear motion. One end of the moving part is connected to the internal threaded sleeve, and the other end is connected to the second end of the connecting sleeve, so that when the internal threaded sleeve moves linearly, it can drive the connecting sleeve to slide along the roller shaft, thereby realizing the adjustment of the position of the roller. In addition, the distance between the two sets of rollers can be flexibly adjusted according to actual needs to adapt to the production of tire sidewalls of different specifications.

[0023] Optionally, it also includes a pressure regulating mechanism connected to the roller pressing mechanism, the pressure regulating mechanism being used to adjust the downward pressing height of the roller pressing wheel to regulate the roller pressing pressure on the tire sidewall.

[0024] By adopting the above technical solution, the pressure regulating mechanism is connected to the roller pressing mechanism, which can adjust the pressing height of the rollers. When adjusting the pressing height of the rollers, the contact state between the rollers and the tire sidewalls can be changed, thereby adjusting the pressing pressure on the tire sidewalls. Since the pressing height of the two rollers is adjusted simultaneously, it helps to ensure that the two tire sidewalls remain of equal length during rolling, avoiding quality problems and material waste caused by uneven stretching of the two tire sidewalls at the rolling station and subsequent forming processes.

[0025] Optionally, the pressure regulating mechanism includes a counterweight mounting component, a counterweight screw, and a counterweight assembly. The counterweight mounting component is connected to one end of the connecting shaft, one end of the counterweight screw is connected to the counterweight mounting component, and the counterweight assembly is screwed to the counterweight screw.

[0026] By adopting the above technical solution, the counterweight mounting component in the pressure regulating mechanism is used to connect the counterweight screw and the connecting shaft, playing a role in fixing and connecting; the counterweight screw provides a track for the installation and movement of the counterweight assembly, allowing the counterweight assembly to be adjusted in position along the screw; the counterweight assembly is screwed onto the counterweight screw, and by adjusting the position of the counterweight assembly on the counterweight screw, the pressure applied to the roller pressing mechanism by the entire pressure regulating mechanism is changed, thereby realizing the adjustment of the roller pressing height, and ultimately accurately adjusting the roller pressing pressure on the tire sidewall, ensuring that the two tire sidewalls always maintain the same length when curling, avoiding quality hazards and material waste caused by inconsistent tire sidewall stretching.

[0027] In summary, this application includes at least the following beneficial technical effects: The support frame of the support mechanism provides a foundation for the entire device. The support components connect to the support frame, serving to stabilize and provide auxiliary support. The connecting frame of the rolling mechanism connects the rolling rollers to the support frame. The shuttle-shaped rolling rollers better adapt to the shape of the tire sidewall, keeping the tire sidewall stable during rolling and reducing the risk of deviation and swaying. The moving conveyor of the tire sidewall drives the rotating rolling rollers connected to the connecting frame to achieve rolling. Two sets of rolling rollers correspond one-to-one with the two tire sidewalls, ensuring that both tire sidewalls are effectively rolled. At the same time, by improving the stability of the tire sidewalls, the length of the two tire sidewalls rolled simultaneously is guaranteed. To maintain consistency, the spacing between the two tire sidewalls changes due to the different positions of the feed belt centers for different widths of tire sidewalls. The spacing adjustment mechanism, connected to the connecting frame, can adjust the spacing between the two sets of rollers, allowing the device to adapt to tire sidewalls of different widths. This ensures more precise processing of the two tire sidewalls during the rolling process, ensuring that the two tire sidewalls remain of equal length during rolling. This avoids the quality risks and material waste issues in the rolling station and subsequent forming processes caused by inconsistent tire sidewall stretching in existing technologies. At the same time, the structure is simple, the operation is convenient, and it can be applied to different tire specifications. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this application discloses a tire sidewall synchronous equal length control device (hereinafter referred to as "device"). The device includes a support mechanism 1, a rolling mechanism 2, and a spacing adjustment mechanism 3. The tire sidewall 100 is conveyed by an existing conveying mechanism to the device, and after being rolled by the device, it is output to the next process.

[0035] The support mechanism 1 includes a support frame 11 and a support component. The support frame 11 provides a support foundation for the entire device, and the support component is connected to the support frame 11 to provide stability and auxiliary support.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the rolling mechanism 2 includes a connecting frame and two sets of rolling rollers 22. One end of the connecting frame is rotatably connected to a support assembly, and the rolling rollers 22 are rotatably connected to the other end of the connecting frame. The two sets of rolling rollers 22 are distributed along their own axial direction and are used to roll the tire sidewalls 100. Each rolling roller 22 corresponds to one tire sidewall 100, ensuring that both tire sidewalls 100 are effectively rolled. The outer circumferential surface of the rolling roller 22 is the rolling surface, which has an arc shape. Along the axial direction of the rolling roller 22, the diameter of the middle section of the rolling roller 22 is larger than the diameter of the two end sections, making the cross-section of the rolling roller 22 extending along the axial direction spindle-shaped. This allows it to adapt to the triangular cross-section of the tire sidewall 100 (not shown in the figure), keeping the tire sidewall 100 stable during the rolling process and reducing the risk of deviation and wobbling. By improving the stability of the tire sidewall 100, the length of the two tire sidewalls 100 rolled simultaneously is kept consistent. Furthermore, the rolling rollers 22 can be made of arc-shaped coated polyurethane material. Specifically, the device can swing up and down by the weight of the roller pressing mechanism 2 and the sag of the tire sidewall 100 to adjust the roller pressure on the tire sidewall 100. Through the friction between the tire sidewall 100 and the roller pressing wheel 22, the tire sidewall 100 can drive the roller pressing wheel 22, which is rotatably connected to the connecting frame, to roll during the moving and conveying process to achieve roller pressing.

[0037] The spacing adjustment mechanism 3 is connected to the connecting frame and is used to adjust the spacing between the two sets of rollers 22. Because the center positions of the feeding belt of tire sidewalls 100 of different widths are different, the spacing between the two tire sidewalls 100 changes during processing. The spacing adjustment mechanism 3, connected to the connecting frame, can adjust the spacing between the two sets of rollers 22, allowing the device to adapt to tire sidewalls 100 of different widths. This ensures more precise processing of the two tire sidewalls 100 during the rolling process, ensuring that the two tire sidewalls 100 maintain equal length during curling. This avoids the quality risks and material waste problems in the curling station and subsequent forming processes caused by inconsistent stretching of the tire sidewalls 100 in existing technologies. Furthermore, the mechanism is simple in structure, easy to operate, and applicable to different tire specifications.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the support assembly includes two sets of support members 121, which are located on opposite sides of the support frame 11. One end of each support member 121 is connected to the support frame 11, and the other end is connected to the rolling mechanism 2. The two sets of support members 121 can stably connect the support frame 11 and the rolling mechanism 2, providing a stable support foundation for the rolling mechanism 2, ensuring the structural stability of the entire device during operation, and enabling the rolling mechanism 2 to perform rolling operations on the tire sidewall 100 normally and accurately.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the connecting frame includes a connecting shaft 211, a roller pressing shaft 212, and two sets of connecting parts 213. The two ends of the connecting shaft 211 are rotatably connected to two support members 121, allowing the connecting frame to be stably connected to the support mechanism 1 and achieving a certain degree of rotational flexibility. The two sets of connecting parts 213 are spaced apart. The first end of each connecting part 213 is connected to the connecting shaft 211, and the two ends of the roller pressing shaft 212 are respectively connected to the second ends of the two sets of connecting parts 213. Both sets of roller pressing wheels 22 are rotatably connected to the roller pressing shaft 212. The connecting parts 213 serve to connect and fix the connecting shaft 211 and the roller pressing shaft 212, ensuring the stability of the structure. The roller pressing shaft 212 provides rotational support for the two sets of roller pressing wheels 22, enabling the roller pressing wheels 22 to rotate stably and roll the tire sidewall 100, ensuring the normal operation of the entire tire sidewall 100 synchronous equal length control device.

[0040] The connector 213 may include a tensioning sleeve 2131 and a connecting rod 2132. The tensioning sleeve 2131 is fitted onto the connecting shaft 211 with an interference fit. One end of the connecting rod 2132 is connected to the tensioning sleeve 2131, and the other end is connected to the roller shaft 212, so that the rotation of the connecting shaft 211 can drive the connecting rod 2132 to rotate around the connecting shaft 211. Specifically, the tensioning sleeve 2131 can be a Z8 type tensioning sleeve 2131. The two rollers 22 are on the same roller shaft 212 with the same pressing height, so that the pressure on the two tire sidewalls 100 is consistent, achieving synchronous stretching, which facilitates consistent winding length in the subsequent coiling process and ensures that the weight of the left and right sides of the tire blank is consistent during the next forming process. Furthermore, the connecting rod 2132 is set perpendicular to the connecting shaft 211, and the two sets of support members 121 are set concentrically, so that the rollers 22 can float up and down easily.

[0041] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the device also includes a pressure regulating mechanism 4. The pressure regulating mechanism 4 is connected to the roller pressing mechanism 2 and is used to adjust the pressing height of the roller pressing roller 22 to adjust the pressing pressure on the tire sidewall 100. When adjusting the pressing height of the roller pressing roller 22, the contact state between the roller pressing roller 22 and the tire sidewall 100 can be changed, thereby adjusting the pressing pressure on the tire sidewall 100. Since the pressing height of the two roller pressing rollers 22 is adjusted simultaneously, it helps to keep the two tire sidewalls 100 of equal length during rolling, avoiding quality problems and material waste caused by inconsistent stretching of the two tire sidewalls 100 at the rolling station and subsequent molding processes.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the pressure regulating mechanism 4 includes a counterweight mounting component 41, a counterweight screw 42, and a counterweight assembly 43. The counterweight mounting component 41 is connected to one end of the connecting shaft 211, and serves to connect the counterweight screw 42 and the connecting shaft 211, providing fixation and connection. One end of the counterweight screw 42 is connected to the counterweight mounting component 41, and the counterweight assembly 43 is screwed onto the counterweight screw 42. The counterweight screw 42 provides a track for the installation and movement of the counterweight assembly 43, allowing the counterweight assembly 43 to be positionally adjusted along the screw. The counterweight mounting component 41 can be a tensioning sleeve structure to reliably transmit the vertically downward tension of the counterweight assembly 43 to the roller 22, thereby adjusting the pressure and friction between the roller 22 and the tire sidewall 100.

[0043] The counterweight screw 42 is perpendicular to the connecting shaft 211. The extension direction of the counterweight screw 42 can be adjusted by adjusting the position of the counterweight assembly 43. The connecting shaft 211 is rotatably connected to the support member 121 through a bearing structure. The counterweight assembly 43 includes several counterweight blocks, the number of which is set as needed. The counterweight assembly 43 is screwed onto the counterweight screw 42. By adjusting the position of the counterweight assembly 43 on the counterweight screw 42, the pressure applied to the roller pressing mechanism 2 by the entire pressure regulating mechanism 4 is changed, thereby adjusting the pressing height of the roller pressing wheel 22. Ultimately, the roller pressing pressure on the tire sidewall 100 can be precisely adjusted to ensure that the two tire sidewalls 100 remain of equal length during rolling, avoiding quality problems and material waste caused by inconsistent stretching of the tire sidewalls 100.

[0044] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the roller pressing mechanism 2 includes two sets of connecting components 23, each corresponding to a roller pressing wheel 22. Each connecting component 23 includes two sets of bearings 231 and two sets of connecting sleeves 232. The two sets of bearings 231 are respectively located at both ends of the roller pressing wheel 22, effectively reducing the frictional resistance during rotation and ensuring smooth rotation. The two sets of connecting sleeves 232 are respectively located at both ends of the roller pressing wheel 22, and are fitted onto the roller pressing shaft 212. The connecting sleeves 232 are slidably connected to the roller pressing shaft 212, allowing the roller pressing wheel 22 to slide along the roller pressing shaft 212, facilitating adjustment of the roller pressing wheel 22's position according to actual needs. Specifically, the bearing 231 is fitted onto the outer circumference of the first end of the connecting sleeve 232, and the end of the roller pressing wheel 22 is fitted onto the outer circumference of the bearing 231, allowing the roller pressing wheel 22 to rotate and slide relative to the roller pressing shaft 212. The bearing 231 can be a deep groove ball bearing 231.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the spacing adjustment mechanism 3 includes a spacing adjustment screw 31 and two sets of moving components 32. The two ends of the spacing adjustment screw 31 are rotatably connected to two sets of connecting parts 213. The spacing adjustment screw 31 is parallel to and spaced apart from the roller shaft 212, providing a track and power transmission path for the two sets of moving components 32. Each moving component 32 corresponds one-to-one with a roller 22. The first end of the moving component 32 is screwed to the spacing adjustment screw 31, and the second end of the moving component 32 is slidably connected to the roller shaft 212. The second end of the moving component 32 is also connected to a connecting sleeve 232 corresponding to a roller 22.

[0046] The second end is slidably connected to the roller shaft 212 to ensure the stability and guidance of the movement of the moving component 32. When the spacing adjustment screw 31 rotates, it can drive the moving component 32 to move axially along the spacing adjustment screw 31. At the same time, the second end of the moving component 32 is connected to a connecting sleeve 232 corresponding to the roller 22, thereby driving the roller 22 to move and achieving the purpose of adjusting the spacing between the two sets of rollers 22, so as to adapt to the production needs of tire sidewalls 100 of different specifications and improve the applicability of the device.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, optionally, the spacing adjustment screw 31 is a bidirectional screw, that is, a screw with two sections of screws with different helical directions. Two sets of moving components 32 are respectively screwed to the different helical sections of the bidirectional screw, so that when the bidirectional screw rotates, the two sets of moving components 32 move in opposite directions. This allows for convenient and precise adjustment of the spacing between the two sets of rollers 22 according to different tire specifications or actual production needs, ensuring that the rollers 22 better fit the tire sidewall 100 and roll it, thereby effectively avoiding the problems caused by the offset and shaking of the tire sidewall 100 in the prior art, and ensuring that the two tire sidewalls 100 always maintain equal length when rolled. The spacing adjustment mechanism 3 also includes two sets of connecting plates 34, which are arranged one-to-one with the connecting parts 213. The connecting plates 34 are set on the connecting parts 213. One end of the connecting plate 34 is rotatably connected to the spacing adjustment screw 31, and the other end of the connecting plate 34 is connected to the roller shaft 212 to improve stability and reliability.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the moving component 32 includes an internal threaded sleeve 321 and a moving part 322. Both the internal threaded sleeve 321 and the connecting sleeve 232 can be made of copper. The internal threaded sleeve 321 is screwed to the pitch adjusting screw 31. One end of the moving part 322 is connected to the internal threaded sleeve 321, and the other end of the moving part 322 is connected to the second end of the connecting sleeve 232. The internal threaded sleeve 321 is screwed to the screw, which can convert the rotational motion of the screw into its own linear motion. The linear motion of the internal threaded sleeve 321 drives the moving part 322 to move linearly, thereby causing the connecting sleeve 232 to move linearly and slide along the roller shaft 212. This allows for adjustment of the position of the roller 22, and thus enables flexible adjustment of the pitch between the two sets of rollers 22 according to actual needs, to adapt to the production of tire sidewalls 100 of different specifications.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the spacing adjustment mechanism 3 includes a rotary handle 33, which is connected to the spacing adjustment screw 31 and used to drive the spacing adjustment screw 31 to rotate. Both the rotary handle 33 and the spacing adjustment screw 31 can be made of aluminum alloy to reduce weight while ensuring strength and wear resistance. Furthermore, bearings and bearing seats can be provided at the locations where the device requires rotatable connection, such as both ends of the spacing adjustment screw 31 and both ends of the connecting shaft 211, to improve the smoothness of rotation.

[0050] It is understandable that the device also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the device can operate normally; the shape, size, material and number of each part of the device can be determined as needed, as long as the corresponding functions can be achieved.

[0051] The implementation principle of the sidewall synchronization and equal length control device in this application embodiment is as follows: The device has a reasonable structural design, and all mechanisms work together. The support mechanism 1 provides stable support, the shuttle-shaped roller 22 of the roller pressing mechanism 2 can adapt well to the shape of the sidewall 100 for roller pressing, the spacing adjustment mechanism 3 can flexibly adjust the spacing of the roller 22 according to the width of the sidewall 100, and the pressure adjustment mechanism 4 can accurately control the roller pressing pressure. Compared with the traditional integral long-axis roller pressing method, it can effectively avoid the sidewall 100 from shifting and shaking, make the two sidewalls 100 stretch evenly, improve the production quality of the sidewall 100, reduce material waste, and at the same time, it is simple and convenient to operate, applicable to the production of sidewalls 100 of different specifications of tires, and has a significant improvement and enhancement to the existing sidewall 100 production technology.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
