Description

Technical Field

[0001] This utility model relates to the technical field of tire manufacturing and processing, and specifically to an exhaust line pressing device. Background Technology

[0002] In the production of rubber tires, the sidewall, as a critical component of the tire structure, directly affects the overall performance and service life of the tire due to its molding quality. During the tire carcass molding process, if the sidewall edges are not tightly pressed together, internal air cannot escape smoothly, especially at the bead area, where air bubbles are prone to form. If these air bubbles are not detected and addressed before vulcanization, they will solidify inside the tire during subsequent vulcanization processes, ultimately leading to quality problems such as bulges and delamination at the bead area of ​​the finished tire. In severe cases, this can even render the entire tire unusable, affecting not only the product qualification rate but also significantly increasing production costs.

[0003] Currently, the industry mainly uses two methods to address the above problems: First, manual inspection and trimming of the tire blank is employed. However, due to the hidden location of air bubbles and the difficulty in identification, missed inspections are common, affecting tire quality and overall production efficiency. Second, during tire blank forming, an exhaust line pressing device is used to press the sidewall edges together to promote air expulsion and reduce air bubble formation. However, current exhaust line pressing devices on the market have fixed structures and poor adaptability, failing to effectively adjust to changes in sidewall thickness. This results in substandard exhaust line pressing, affecting exhaust performance and failing to fundamentally solve the air bubble defect problem.

[0004] Therefore, existing technologies still need further development. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, according to one aspect of the present invention: an exhaust line pressing device is provided, comprising: a tire sidewall exhaust pressing roller and an adjusting structure, wherein the tire sidewall exhaust pressing roller is movably disposed; a plurality of exhaust lines are arranged around the outer circumferential wall of the tire sidewall exhaust pressing roller, and a preset angle is formed between the axis of the tire sidewall exhaust pressing roller and the horizontal direction, the preset angle being greater than or equal to 0° and less than 90°; the adjusting structure is adjustablely connected to the tire sidewall exhaust pressing roller, and the adjusting structure is used to adjust the angle of the preset angle.

[0007] Furthermore, the exhaust line pressing device also includes: a connecting structure, which is oscillatingly arranged relative to the tire sidewall, and the tire sidewall exhaust pressing roller is rotatably arranged at the connecting end of the connecting structure; the connecting end of the adjusting structure is connected to the driving end of the connecting structure, so as to drive the connecting structure to oscillate through the adjusting structure and adjust the angle of the preset included angle.

[0008] Furthermore, the exhaust line pressing device also includes: a mounting structure, wherein the connecting structure is swayably disposed at the bottom of the mounting structure; and an adjusting structure including: an adjusting screw, wherein the connecting end of the adjusting screw passes through the mounting structure and is connected to the driving end of the connecting structure; the adjusting screw is threadedly engaged with the mounting structure.

[0009] Furthermore, the adjustment structure also includes a first gripper, which is disposed on the end of the adjustment screw away from the connecting structure.

[0010] Furthermore, the exhaust line pressing device also includes a lifting structure, the drive end of which is connected to the mounting structure, and the lifting structure drives the tire sidewall exhaust pressing roller to move vertically through the mounting structure.

[0011] Furthermore, the exhaust line pressing device also includes: a movable structure connected to a lifting structure, wherein the movable structure drives the tire sidewall exhaust pressing roller to move horizontally via the lifting structure.

[0012] Furthermore, the movable structure includes: a movable member, which is movably disposed in the horizontal direction; the movable member is connected to the lifting structure, and the movable member is located on one side of the lifting structure.

[0013] Furthermore, the movable structure also includes: a screw, which extends along the moving direction of the movable member and is rotatably mounted; the movable member is provided with an internal thread hole that matches the external thread of the screw, and the movable member is threadedly engaged with the screw so that the movable member can be moved by the movement of the screw.

[0014] Furthermore, the screw is provided with a first threaded section and a second threaded section, the first threaded section and the second threaded section have opposite directions of rotation, and there are at least two moving parts. One of the at least two moving parts has a first internal threaded hole that mates with the first threaded section, and the other of the at least two moving parts has a second internal threaded hole that mates with the second threaded section, so that the screw can drive one moving part and the other moving part to move closer or further apart.

[0015] Furthermore, the exhaust line pressing device also includes: a frame, on which the screw is rotatably mounted; a slide rail, which is mounted on the frame and extends along the extension direction of the screw; and a slider adapted to the slide rail is provided on the side of the moving part near the slide rail, which is slidably mounted on the slide rail along the extension direction of the slide rail.

[0016] Beneficial effects: The present invention provides an exhaust line pressing device, comprising: a tire sidewall exhaust pressing roller and an adjusting structure. The tire sidewall exhaust pressing roller has multiple exhaust lines arranged around its outer circumferential wall for pressing exhaust lines onto the wear-resistant area of ​​the tire sidewall. The adjusting structure is adjustablely connected to the tire sidewall exhaust pressing roller to adjust the size of a preset angle by adjusting the tilt angle of the tire sidewall exhaust pressing roller. The tire sidewall exhaust pressing roller is movably arranged such that its axis forms a preset angle with the horizontal direction, which is greater than or equal to 0° and less than 90°. The adjusting structure allows for flexible adjustment of this preset angle, thereby achieving dynamic control of the contact angle and fit between the pressing roller and the wear-resistant area of ​​the tire sidewall.

[0017] Therefore, this invention, by setting an adjustment structure to change the angle between the axis of the tire sidewall venting and pressing roller and the horizontal direction, alters the "angle" and "fit" of the working surface of the tire sidewall venting and pressing roller in contact with the wear-resistant area of ​​the tire sidewall. This allows the tire sidewall venting and pressing roller to flexibly adjust its working angle according to changes in tire sidewall thickness, achieving good fit with tire sidewalls of different models and thicknesses, significantly improving the applicability and versatility of the device. Simultaneously, by changing the tilt angle of the tire sidewall venting and pressing roller, the contact surface and pressing direction with the wear-resistant area of ​​the tire sidewall can be effectively adjusted, resulting in a more uniform and tighter pressing between the venting line and the tire sidewall rubber. This ensures that the venting line is pressed more evenly and tightly into the tire sidewall rubber, greatly improving the consistency and quality of venting line pressing. Furthermore, by adjusting the preset angle, the pressure is applied more evenly to the venting line and its surrounding area, avoiding excessively high or insufficient local pressure caused by a fixed angle. This uniform pressure effectively ensures the quality of the pressing process, thereby reducing air bubble defects caused by poor pressing at the source and significantly improving tire molding quality and finished product qualification rate. The exhaust line pressing device of this invention is easy to operate and effectively solves the problems of fixed structure, poor adaptability, and inability to effectively adjust to changes in tire sidewall thickness in existing exhaust line pressing devices.

[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 should fall within the scope of protection of the present application.

[0021] In existing technologies, during tire green tire forming, the sidewall components are typically produced separately and then assembled. This sidewall includes a wear-resistant zone located at the edge, and the exhaust line pressing device primarily performs pressing operations on this area. Because this wear-resistant zone has a certain angle relative to the middle part of the sidewall, and the degree of this angle varies with the sidewall thickness, higher requirements are placed on the adaptability of the exhaust line pressing device.

[0022] However, most exhaust line pressing devices currently on the market suffer from fixed structures and limited adjustability. They cannot effectively adjust the pressing angle according to changes in tire sidewall thickness, resulting in poor adhesion between the pressing roller and the wear-resistant area of ​​the tire sidewall. This poor angle adaptation directly causes substandard exhaust line pressing, affecting exhaust performance and, in severe cases, even causing air bubble defects and reducing tire forming quality.

[0023] To address the aforementioned technical deficiencies, this invention provides a targeted improvement: a venting line pressing device with an adjustable pressing angle. This adapts to variations in sidewall thickness and wear zone inclination angle, thereby enhancing the precision and stability of venting line pressing, ensuring effective venting, and improving tire forming quality. The specific structure is as follows: Please see Figures 1 to 4According to an embodiment of the present invention, an exhaust line pressing device is provided, comprising: a tire sidewall exhaust pressing roller 1 and an adjusting structure 2. The tire sidewall exhaust pressing roller 1 is movably disposed; a plurality of exhaust lines are arranged around the outer circumferential wall of the tire sidewall exhaust pressing roller 1, and a preset angle is formed between the axis of the tire sidewall exhaust pressing roller 1 and the horizontal direction, the preset angle being greater than or equal to 0° and less than 90°; the adjusting structure 2 is adjustablely connected to the tire sidewall exhaust pressing roller 1, and the adjusting structure 2 is used to adjust the angle of the preset angle.

[0024] As can be seen, the exhaust line pressing device provided by this utility model includes: a tire sidewall exhaust pressing roller 1 and an adjusting structure 2. The tire sidewall exhaust pressing roller 1 has multiple exhaust lines arranged around its outer circumferential wall for pressing the exhaust lines onto the wear-resistant area of ​​the tire sidewall. The adjusting structure 2 is adjustablely connected to the tire sidewall exhaust pressing roller 1, so as to adjust the size of the preset angle by adjusting the tilt angle of the tire sidewall exhaust pressing roller 1. The tire sidewall exhaust pressing roller 1 is movably arranged, and its axis forms a preset angle with the horizontal direction, which is greater than or equal to 0° and less than 90°. The adjusting structure 2 allows for flexible adjustment of this preset angle, thereby achieving dynamic control of the contact angle and fit between the pressing roller and the wear-resistant area of ​​the tire sidewall.

[0025] Therefore, this invention, by setting the adjustment structure 2, changes the angle and fit between the working surface of the tire sidewall venting and pressing roller 1 and the wear-resistant area of ​​the tire sidewall by altering the angle between the axis of the roller and the horizontal direction. This allows the tire sidewall venting and pressing roller 1 to flexibly adjust its working angle according to changes in tire sidewall thickness, achieving good fit with tire sidewalls of different models and thicknesses, significantly improving the applicability and versatility of the device. Simultaneously, by changing the tilt angle of the tire sidewall venting and pressing roller 1, the contact surface and pressing direction with the wear-resistant area of ​​the tire sidewall can be effectively adjusted, resulting in a more uniform and tighter press between the venting line and the tire sidewall rubber. This ensures that the venting line is pressed more evenly and tightly into the tire sidewall rubber, greatly improving the consistency and quality of the venting line pressing. Furthermore, by adjusting the preset angle, the pressure is applied more evenly to the venting line and its surrounding area, avoiding excessively high or insufficient local pressure caused by a fixed angle. This uniform pressure effectively ensures the quality of the pressing process, thereby reducing air bubble defects caused by poor pressing at the source and significantly improving tire molding quality and finished product qualification rate. The exhaust line pressing device of this invention is easy to operate and effectively solves the problems of fixed structure, poor adaptability, and inability to effectively adjust to changes in tire sidewall thickness in existing exhaust line pressing devices.

[0026] Optionally, the tire sidewall exhaust pressing roller 1 is an exhaust line wheel.

[0027] Specifically, such as Figures 1 to 4As shown, the exhaust line pressing device further includes: a connecting structure 3, which is oscillatingly arranged relative to the tire sidewall, and the tire sidewall exhaust pressing roller 1 is rotatably arranged at the connecting end of the connecting structure 3; the connecting end of the adjusting structure 2 is connected to the driving end of the connecting structure 3 so that the connecting structure 3 can be oscillating by the adjusting structure 2 to adjust the angle of the preset included angle.

[0028] With the above-described structural configuration, the adjusting structure 2 drives the connecting structure 3 to swing at a small angle, utilizing the leverage effect to achieve a large-angle adjustment of the tire sidewall venting and pressing roller 1. This design not only simplifies the adjustment steps but also significantly improves the response speed and accuracy of the adjustment, ensuring that operators can quickly and accurately complete the angle adjustment. Simultaneously, the connecting structure 3 provides stable support and a consistent motion trajectory for the tire sidewall venting and pressing roller 1, ensuring that it maintains the correct pressing position and angle during operation. This helps improve pressing quality and reduce air bubble defects caused by unstable pressing. Furthermore, the adjusting structure 2 acts on the end of the connecting structure 3 furthest from the tire sidewall venting and pressing roller 1. Due to the long lever arm, a small adjusting force is sufficient to overcome the reaction force of the tire sidewall venting and pressing roller 1 during operation. This design makes the adjustment process more effortless and smooth, reduces operational difficulty, and improves the comfort of using the equipment. In addition, the tire sidewall venting and pressing roller 1 is rotatably positioned at the end of the connecting structure 3 near the wear-resistant area of ​​the tire sidewall, ensuring that it rolls smoothly with the conveying direction of the tire sidewall during the pressing process. This design effectively reduces frictional resistance, avoids the risk of scratches on the tire sidewall, and ensures the uniform transmission of pressing force, further improving the pressing effect.

[0029] Further, the connecting structure 3 includes: a swing arm 31, a first connecting member 32, and a first fixing pin 33. The swing arm 31 extends along a preset direction. The tire sidewall exhaust pressing roller 1 is rotatably disposed on one end of the swing arm 31. The first connecting member 32 is disposed on the end of the swing arm 31 away from the tire sidewall exhaust pressing roller 1. The first connecting member 32 is provided with a first opening groove 320. The first fixing pin 33 is inserted into the first connecting member 32 and is fixedly connected to the first connecting member 32, with at least a portion of the first fixing pin 33 located within the first opening groove 320. The connecting end of the adjusting structure 2 passes through the first opening groove 320 and is inserted into the first fixing pin 33, and is fixedly connected to the first fixing pin 33. The extending direction of the first fixing pin 33 is perpendicular to the extending direction of the swing arm 31. The end of the swing arm 31 away from the first connecting member 32 forms the connecting end of the connecting structure 3, and the first fixing pin 33 forms the driving end of the connecting structure 3.

[0030] Specifically, such as Figures 1 to 4As shown, the exhaust line pressing device also includes: a mounting structure 4, and a connecting structure 3 is swayably set at the bottom of the mounting structure 4; the adjusting structure 2 includes: an adjusting screw 21, the connecting end of the adjusting screw 21 passes through the mounting structure 4 and is connected to the connecting structure 3, and the connecting end of the adjusting screw 21 is located at the end of the connecting structure 3 away from the tire sidewall exhaust pressing roller 1; the adjusting screw 21 is threadedly engaged with the mounting structure 4.

[0031] With the above-described structural configuration, the oscillating displacement of the connecting structure 3 can be precisely controlled by rotating the adjusting screw 21 and utilizing the precision transmission characteristics of the threaded connection. Furthermore, due to the continuous and linear displacement output characteristics of the threaded pair, the preset angle can be finely and steplessly adjusted continuously. Operators can make fine adjustments based on specific parameters of the tire sidewall (such as thickness and curvature changes) to ensure that the tire sidewall exhaust pressing roller 1 is always in the optimal working position, improving the consistency and reliability of the exhaust line pressing. Simultaneously, the threaded connection has inherent self-locking properties. Once adjusted to the correct position and the screw rotation stopped, this structure can reliably resist the vibrations and reaction forces generated during the pressing process without the need for additional locking devices, firmly maintaining the set angle and ensuring the stability and consistency of the pressing process.

[0032] Furthermore, such as Figure 4 As shown, the adjustment structure 2 also includes a first gripping member 22, which is disposed on the end of the adjustment screw 21 away from the connecting structure 3.

[0033] Furthermore, such as Figures 1 to 3 As shown, the mounting structure 4 includes a support frame 41 and a second fixing pin 42. A swing arm 31 is swayably mounted at the bottom of the support frame 41. A second opening groove 410 is provided on the side of the support frame 41 away from the tire sidewall exhaust pressing roller 1. The second fixing pin 42 is inserted into the support frame 41 and is fixedly connected to the support frame 41. The extension direction of the second fixing pin 42 is consistent with the extension direction of the first fixing pin 33. An internal threaded hole adapted to the adjusting screw 21 is provided on the second fixing pin 42. The internal threaded hole extends along the moving direction of the adjusting screw 21, and the external thread of the adjusting screw 21 is threadedly engaged with the internal threaded hole of the second fixing pin 42.

[0034] Specifically, such as Figures 1 to 3As shown, the exhaust line pressing device also includes a lifting structure 5. The drive end of the lifting structure 5 is connected to the mounting structure 4. The lifting structure 5 drives the tire sidewall exhaust pressing roller 1 to move vertically through the mounting structure 4. With this structural arrangement, the lifting structure 5 can move the tire sidewall exhaust pressing roller 1 closer to or further away from the tire sidewall. At the same time, it can adaptively adjust the working height of the tire sidewall exhaust pressing roller 1 according to the change in tire sidewall thickness. This ensures that the tire sidewall exhaust pressing roller 1 is accurately aligned with the target pressing area of ​​tire sidewalls of different specifications and achieves effective pressing, thereby realizing precise and efficient exhaust line pressing operations and enhancing the versatility and adaptability of the device.

[0035] Optionally, the lifting structure 5 is a drive cylinder.

[0036] Furthermore, there are at least two tire sidewall venting pressing rollers 1. By setting multiple tire sidewall venting pressing rollers 1, venting lines can be pressed onto multiple wear-resistant areas of the tire sidewall, thereby improving the production efficiency of the venting line pressing device.

[0037] Furthermore, there are at least two of each of the adjustment structure 2, connection structure 3, installation structure 4, and lifting structure 5, and each adjustment structure 2, each connection structure 3, each installation structure 4, and each lifting structure 5 is set up in a one-to-one correspondence with each tire sidewall exhaust pressure roller 1.

[0038] Specifically, such as Figure 1 and Figure 3 As shown, the exhaust line pressing device also includes a movable structure 6, which is connected to a lifting structure 5. The movable structure 6 drives the tire sidewall exhaust pressing roller 1 to move horizontally via the lifting structure 5. With this structural arrangement, by setting the movable structure 6, the position of the tire sidewall exhaust pressing roller 1 relative to the tire sidewall can be flexibly adjusted according to the width of different tire sidewall specifications, ensuring accurate alignment with the target pressing area of ​​the tire sidewall, thereby achieving efficient and precise pressing operations for tire sidewalls of different widths.

[0039] Furthermore, such as Figure 1 and Figure 3 As shown, the movable structure 6 includes: a movable member 61, which is movably arranged in the horizontal direction; the movable member 61 is connected to the lifting structure 5, and the movable member 61 is located on one side of the lifting structure 5.

[0040] Furthermore, such as Figure 1 and Figure 3 As shown, the movable structure 6 also includes: a screw 62, which extends along the moving direction of the movable member 61 and is rotatably disposed; the movable member 61 is provided with an internal thread hole that matches the external thread of the screw 62, and the movable member 61 is threadedly engaged with the screw 62 so that the movable member 61 can be moved by the movement of the screw 62.

[0041] With the above-described structure, the threaded engagement between the screw 62 and the moving part 61 enables high-precision and stable horizontal movement control of the tire sidewall venting and pressing roller 1. This ensures the positioning accuracy of the tire sidewall venting and pressing roller 1 relative to the target pressing area of ​​the tire sidewall, improving the accuracy of the pressing position. By driving the moving part 61 with the screw 62, it can flexibly adapt to tire sidewalls of different widths, ensuring that the tire sidewall venting and pressing roller 1 is always accurately aligned with the target pressing area, significantly improving the versatility and adaptability of the device.

[0042] Furthermore, the screw 62 is provided with a first threaded section 621 and a second threaded section 622, the first threaded section 621 and the second threaded section 622 having opposite directions of rotation. There are at least two moving parts 61, one of which has a first internal threaded hole that mates with the first threaded section 621, and the other of which has a second internal threaded hole that mates with the second threaded section 622, so that the screw 62 can drive one moving part 61 and the other moving part 61 to move closer or further apart. The moving parts 61 are arranged in a one-to-one correspondence with the tire sidewall exhaust pressure roller 1.

[0043] By adopting the above-mentioned structural configuration, by setting a first threaded section 621 and a second threaded section 622 with opposite directions of rotation on the screw 62, and by having at least two moving parts 61 respectively engage with the corresponding threaded sections, not only is synchronous and precise adjustment of at least two tire sidewall exhaust pressing rollers 1 achieved, but the ease of operation, pressing consistency and production efficiency of the equipment are also significantly improved.

[0044] Optionally, there are two movable parts 61.

[0045] Furthermore, such as Figure 1 As shown, the moving structure 6 also includes a second gripper 63, which is disposed on one end of the screw 62.

[0046] Specifically, such as Figure 1 As shown, the exhaust line pressing device also includes: a frame 7, a screw 62 rotatably mounted on the frame 7; a slide rail 8 mounted on the frame 7, the slide rail 8 extending along the extension direction of the screw 62; and a slider 9 adapted to the slide rail 8 is provided on the side of the moving part 61 near the slide rail 8, the slider 9 being slidably mounted on the slide rail 8 along the extension direction of the slide rail 8.

[0047] With the above-mentioned structural configuration, the guide structure formed by the slide rail 8 and the slider 9 has good straightness and guiding accuracy, which can effectively prevent the moving part 61 from deviating or shaking during the movement, thereby ensuring the moving accuracy and running stability of the tire sidewall exhaust pressing roller 1 in the horizontal direction.

[0048] In the prior art, the tire sidewall has a sheet-like structure, and the aforementioned horizontal direction can be understood as the lateral direction of the tire sidewall. Simultaneously, the aforementioned horizontal direction can be understood as the width direction of the frame 7, as shown in the figure. Figure 3 The direction indicated by the middle arrow B.

[0049] Optionally, the operation of the exhaust line pressing device is as follows: 1. Adjust the tilt angle of the tire sidewall exhaust pressure roller. According to the tire sidewall specifications of the exhaust line to be pressed, the operator fine-tunes the tilt angle of the pressing roller by rotating the adjusting screw 21 corresponding to the tire sidewall exhaust pressing roller 1. This adjustment matches the tilt angle of the tire sidewall exhaust pressing roller 1 with the tilt angle of the wear-resistant area of ​​the tire sidewall, thereby ensuring good adhesion between the pressing roller and the wear-resistant area of ​​the tire sidewall during exhaust line pressing.

[0050] Through this step, the tire sidewall venting and pressing roller 1 can achieve a more uniform and tighter pressing effect on the wear-resistant area of ​​the tire sidewall, so that the venting line is pressed into the tire sidewall rubber more effectively, significantly improving the venting effect and pressing quality.

[0051] 2. Adjust the distance between the tire sidewall exhaust pressure rollers. After the angle adjustment is completed, the staff manually rotates the second gripper 63 to drive the screw 62 to rotate according to the target pressing area (i.e. the wear-resistant area of ​​the tire sidewall) of the tire sidewall to be pressed. This drives the tire sidewall vent pressing roller 1 to move horizontally through the moving part 61, so that the tire sidewall vent pressing roller 1 is aligned with the target pressing area (i.e. the wear-resistant area of ​​the tire sidewall) located below it.

[0052] 3. Perform pressing. After adjustment, the lifting structure 5 (i.e., the drive cylinder) is activated, causing the lifting structure 5 to move the tire sidewall venting and pressing roller 1 closer to the target pressing area of ​​the tire sidewall (i.e., the wear-resistant area of ​​the tire sidewall), so that the tire sidewall venting and pressing roller 1 presses the target pressing area of ​​the tire sidewall. During the process of the tire sidewall being conveyed by the conveying device along the set direction, the tire sidewall venting and pressing roller 1 rolls with the tire sidewall surface to perform continuous pressing, so as to achieve full adhesion between the venting line and the tire sidewall rubber.

[0053] After the pressing is completed, the lifting structure 5 drives the tire sidewall exhaust pressing roller 1 to move upward away from the tire sidewall, completing one pressing cycle.

[0054] It should be noted that the tire sidewall is continuously conveyed by a conveying device, and the tire sidewall exhaust pressing roller 1 is set above the conveying device, which can complete the dynamic pressing operation during the movement of the tire sidewall, ensuring that the pressing process is continuous, efficient and stable.
