Description

Technical Field

[0001] This utility model relates to the technical field of tire processing, specifically to a rubber pad pressing device and a rubber pad feeding device having the same. Background Technology

[0002] In existing technology, the padding rollers equipped with three-drum tire blank forming machines typically adopt a single long rubber roller structure. This roller is driven by a cylinder located in the middle of the pressing frame to achieve the downward pressing action, and the pressure applied by the cylinder drives the entire roller to press the padding as a whole.

[0003] However, in practical applications, it has been found that because the cross-section of the rubber pad is usually trapezoidal, its thickness distribution in the width direction is not uniform, resulting in significant uneven pressure distribution during the pressing process using a traditional long rubber roller. Specifically, the pressing force is mainly concentrated in the central area driven by the cylinder, where the pressing effect is better; while the inner and outer edges of the rubber pad are far from the center of pressure, and the entire roller lacks elastic compensation for local areas, making it difficult to obtain sufficient pressing force, resulting in insufficient pressing strength in these areas.

[0004] The aforementioned uneven pressing directly results in insufficient adhesion between the inner and outer edges of the rubber pad and the tire body, easily leading to gaps or poor adhesion. During the subsequent vulcanization process, these poorly bonded areas are prone to air trapping, which in turn causes typical quality defects in the finished tire, such as tread bubbles and shoulder bubbles. This seriously affects the tire's appearance and performance, and may even pose safety hazards.

[0005] Therefore, the existing technology still needs further development. Utility Model Content

[0017] Beneficial effects:

[0018] The present invention provides a padding pressing device comprising a feeding rack and a pressing component. The feeding rack not only carries the padding to be pressed but also guides it, ensuring precise overlap of the padding onto the forming drum. The feeding rack extends along the conveying direction of the padding, with its end near the forming drum defined as the output end. The pressing component is located at the output end of the feeding rack and is rotatably connected to it in the lateral direction of the feeding rack, allowing the pressing component to tilt relative to the feeding rack. This design enables the pressing component to have flexible tilting capabilities, allowing its pressing portion to move closer to or further away from the forming drum according to process requirements.

This structural design enhances the versatility and applicability of the device, improving its operational flexibility and stability under different working conditions. This rubber pad pressing device effectively solves the technical problem in existing technologies using a single long rubber roller, where uneven pressure distribution leads to insufficient bonding between the inner and outer edges of the rubber pad and the tire body.

[0027] 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.

[0028] Please see Figures 1 to 3 According to an embodiment of the present invention, a padding pressing device is provided, comprising: a feeding rack 1 and a pressing component 2. The feeding rack 1 extends along the conveying direction of the padding and is used to carry and guide the padding. The pressing component 2 is located at the output end of the feeding rack 1 and is rotatably arranged around the transverse direction of the feeding rack 1 so that the pressing portion of the pressing component 2 is away from or close to the molding drum. There are at least two pressing portions, and each pressing portion is spaced apart along the width of the padding.

[0029] As can be seen, the adhesive pad pressing device provided by this utility model includes a feeding rack 1 and a pressing component 2. The feeding rack 1 not only carries the adhesive pad to be pressed but also guides it, ensuring that the adhesive pad can accurately overlap the forming drum. The feeding rack 1 extends along the conveying direction of the adhesive pad, with its end near the forming drum defined as the output end. The pressing component 2 is located at the output end of the feeding rack 1 and is rotatably connected around the transverse direction of the feeding rack 1, allowing the pressing component 2 to tilt relative to the feeding rack 1. This design enables the pressing component 2 to have flexible tilting function, allowing its pressing part to move away from or closer to the forming drum according to process requirements. After the adhesive pad is overlapped, the pressing component 2 moves towards the forming drum, causing the pressing part to tightly adhere and press against the adhesive pad surface, thereby ensuring a good fit between the adhesive pad and the forming drum.

[0030] Furthermore, the pressing component 2 has at least two pressing sections, spaced apart along the width of the pad. This multi-point pressing structure enables uniform and reliable pressing across the entire width of the pad. Compared to the traditional method where a single long rubber roller can only apply effective pressure to the central area, this multi-pressing section design significantly improves the bonding effect at the edge of the pad, avoiding quality defects such as poor bonding, bubbles, and wrinkles caused by insufficient or excessive local pressing. This comprehensively improves the pressing quality, resulting in a tighter, smoother, and stronger bond between the pad and the molding drum.

[0031] Furthermore, the rotatable connection structure of the pressing component 2 provides it with excellent adaptability and adjustability. Depending on the specifications, thickness, or material of the rubber pads, as well as the specific shape and size requirements of the forming drum, operators can flexibly adjust the angle and pressing pressure of the pressing component 2 to achieve optimal bonding. This structural design enhances the versatility and applicability of the device, improving the operational flexibility and stability of the equipment under different working conditions. This rubber pad pressing device effectively solves the technical problem in existing technologies where the rubber pad pressing roller using a single long rubber roller exhibits significant uneven pressure distribution, resulting in insufficient bonding between the inner and outer edges of the rubber pad and the tire body.

[0032] Among them, the horizontal direction of the feeding rack 1 is as follows: Figure 2 The direction indicated by the middle arrow B.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the pressing component 2 includes: a fixed plate 21 and at least two pressure rollers 22. The fixed plate 21 extends along the transverse direction of the feed rack 1 and is rotatably arranged around the transverse direction of the feed rack 1. Each pressure roller 22 extends along the extension direction of the fixed plate 21 and is spaced apart at the bottom of the fixed plate 21 along the extension direction of the fixed plate 21. Each pressure roller 22 is movably arranged relative to the fixed plate 21. The pressure rollers 22 form a pressing part.

[0034] This structural design, with the fixed plate 21 providing stable support for the pressure roller 22, ensures the overall structural stability of the pressing components, guarantees a stable and reliable pressing process, and extends the service life of the device. Simultaneously, the pressure roller 22 can move flexibly relative to the fixed plate, adjusting its own position and rotating with the forming drum. This allows it to effectively press the rubber pad while adapting to different specifications, thicknesses, materials, and the shape and size of the forming drum, making the device highly versatile and meeting various working conditions.

[0035] Preferably, such as Figure 1 and Figure 2 As shown, there are two pressure rollers 22.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, the pressing component 2 further includes: at least two support components 23, each support component 23 being arranged in a one-to-one correspondence with each pressure roller 22, each support component 23 having an installation space 230, and each pressure roller 22 being rotatably arranged within the corresponding installation space 230; each support component 23 being spaced apart on the fixing plate 21 along the extension direction of the fixing plate 21, and at least a portion of each support component 23 being located at the bottom of the fixing plate 21; each support component being adjustable in position relative to the fixing plate 21 along the extension direction of the fixing plate 21.

[0037] This structural arrangement, with support components 23 of the same specifications, provides stable support for the pressure roller 22, ensuring its stability and accuracy during rotation. By rotatably mounting the pressure roller 22 within the installation space 230 of the support components 23, good contact between the pressure roller 22 and the padding material and the forming drum is guaranteed during the pressing process, resulting in a uniform and tight pressing effect. Simultaneously, the positions of each support component 23 relative to the fixed plate 21 along its extension direction are adjustable, allowing for flexible adjustment of the pressure roller 22's position according to different specifications and thicknesses of padding material and the shape and size of the forming drum. This enables the pressing component 2 to adapt to various production needs, exhibiting broad versatility and flexibility. Furthermore, the adjustable design of the support components 23 facilitates fine-tuning of the pressure roller 22's position during production to optimize the pressing effect and accommodate subtle variations in padding material or forming drums from different batches.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the support assembly 23 includes: a first support plate 231 and a second support plate 232, which are spaced apart along the extension direction of the fixed plate 21, forming an installation space 230 between them; a first adjusting member 233 and a second adjusting member 234, which are adjustablely positioned on the fixed plate 21 along the extension direction of the fixed plate 21, with the connecting ends of the first adjusting member 233 and the second adjusting member 234 passing through the fixed plate 21 and connecting to the first support plate 231 and the second support plate 232, respectively, so as to adjust the position of the first adjusting member 233 and the second adjusting member 234 relative to the fixed plate 21, and adjust the position of the pressure roller 22 relative to the padding rubber.

[0039] With this structural arrangement, the first support plate 231 and the second support plate 232 are spaced apart along the extension direction of the fixed plate 21, forming an installation space 230. This provides stable support for the pressure roller 22, ensuring its stable operation during the pressing process, good contact with the padding rubber and the forming drum, achieving uniform and tight pressing, and improving pressing quality. Simultaneously, the first support plate 231 and the second support plate 232 are connected to the fixed plate 21 via the first adjusting member 233 and the second adjusting member 234, allowing for flexible adjustment of the pressure roller 22 position. This enables precise pressing, adapting to padding rubber of different specifications and thicknesses, as well as the shape and size of the forming drum, meeting diverse production needs and improving product quality and yield. Furthermore, by adjusting the position of the first adjusting member 233 and / or the second adjusting member 234 relative to the fixed plate 21, the size of the installation space 230 can also be adjusted to accommodate pressure rollers 22 of different specifications, further enhancing the versatility and flexibility of the equipment.

[0040] Furthermore, the support assembly 23 also includes a support rod, which is disposed within the installation space 230 and extends along the extension direction of the fixed plate 21. The two ends of the support rod are respectively fixedly connected to the first support plate 231 and the second support plate 232, and the pressure roller 22 is rotatably sleeved on the support rod.

[0041] In this embodiment, the first configuration of each group of adjustment holes is as follows: Figure 1 and Figure 2 As shown, the fixing plate 21 is provided with at least two sets of adjustment holes, each set of adjustment holes is provided in a one-to-one correspondence with each support component 23, and each set of adjustment holes extends along the extension direction of the fixing plate 21; each set of adjustment holes includes: at least one first adjustment hole 211 and at least one second adjustment hole 212, the first adjustment hole 211 and the second adjustment hole 212 are spaced apart along the extension direction of the fixing plate 21; wherein, there is at least one first adjustment member 233 and at least one second adjustment member 234, the first adjustment member 233 is provided in a one-to-one correspondence with the first adjustment hole 211, the connecting end of the first adjustment member 233 passes through the corresponding first adjustment hole 211 and connects to the first support plate 231, and the position of the first adjustment member 233 is adjustable on the fixing plate 21 along the extension direction of the first adjustment hole 211; the second adjustment member 234 is provided in a one-to-one correspondence with the second adjustment hole 212, the connecting end of the second adjustment member 234 passes through the corresponding second adjustment hole 212 and connects to the second support plate 232, and the position of the second adjustment member 234 is adjustable on the fixing plate 21 along the extension direction of the second adjustment hole 212.

[0042] This structural design, with its adjustable holes, allows for more flexible and precise adjustment of the support assembly 23. By moving the adjusting element along the adjustable holes, the position of the pressure roller 22 on the fixed plate 21 can be precisely controlled, thus better adapting to different specifications and thicknesses of padding materials and the shape and size of the forming drum. Furthermore, the adjustable holes facilitate the installation and removal of the support assembly 23. When it is necessary to replace or maintain the pressure roller 22, the adjusting element can be easily removed from the adjustable holes, allowing for the disassembly and reinstallation of the support assembly 23.

[0043] Furthermore, the first adjusting member 233 is the first adjusting bolt, and the second adjusting member 234 is the second adjusting bolt.

[0044] Optionally, when it is necessary to adjust the position of the pressure roller 22 according to the specifications of the padding, first loosen the first adjusting bolt and the second adjusting bolt so that their tops are away from the fixed plate 21. Then, move the first adjusting bolt and the second adjusting bolt along the extension direction of the first adjusting hole 211 and the extension direction of the second adjusting hole 212, thereby moving the first support plate 231 and the second support plate 232, thus adjusting the position of the pressure roller 22 so that the pressure roller 22 is in the target position. After the adjustment is in place, tighten the first adjusting bolt and the second adjusting bolt so that their tops are pressed against the fixed plate 21, thereby fixing the first support plate and the second support plate relative to the fixed plate 21.

[0045] Preferably, there are two of each of the first adjusting hole 211, the second adjusting hole 212, the first adjusting member 233, and the second adjusting member 234. The two first adjusting holes 211 and the two second adjusting holes 212 are spaced apart on the fixed plate 21 along the conveying direction of the padding adhesive. Each first adjusting member 233 passes through the corresponding first adjusting hole 211 and is connected to the corresponding first support plate 231. Each second adjusting member 234 passes through the corresponding second adjusting hole 212 and is connected to the corresponding second support plate 232.

[0046] The first adjusting member 233 is detachably connected to the first support plate 231, and the second adjusting member 234 is detachably connected to the second support plate 232.

[0047] In this embodiment, the second configuration of each set of adjustment holes is that each set of adjustment holes can also be at least one adjustment hole. The adjustment holes extend along the extension direction of the fixed plate 21. There is at least one first adjustment member 233 and at least one second adjustment member 234. The first adjustment member 233 is configured to correspond one-to-one with the first adjustment hole 211, and the second adjustment member 234 is configured to correspond one-to-one with the second adjustment hole 212. The positions of the first adjustment member 233 and the second adjustment member 234 are adjustable on the fixed plate 21 along the extension direction of the adjustment holes. The connecting end of the first adjustment member 233 and the connecting end of the second adjustment member 234 pass through the adjustment holes and are connected to the first support plate 231 and the second support plate 232 respectively.

[0048] Preferably, there are two adjusting holes, two first adjusting members 233 and two second adjusting members 234. The adjusting holes are spaced apart on the fixed plate 21 along the conveying direction of the padding adhesive. Each first adjusting member 233 and each second adjusting member 234 passes through the corresponding adjusting hole and is connected to the corresponding first support plate 231 and second support plate 232 respectively.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, the pressing component 2 also includes: two supports 24, which are spaced apart on the feeding rack 1 along the transverse direction of the feeding rack 1, and the two supports 24 are rotatably arranged relative to the feeding rack 1; a fixing plate 21 is disposed between the two supports 24, the fixing plate 21 is located at the end of the support 24 away from the feeding rack 1, and the fixing plate 21 is connected to the two supports 24 respectively.

[0050] With this structural arrangement, the two supports 24 are spaced apart along the transverse direction of the feed rack 1, providing a stable support base for the fixing plate 21. This design ensures the stability of the fixing plate 21 during operation, thereby improving the overall stability of the pressing component 2 and contributing to improved pressing quality. Furthermore, since the two supports 24 can rotate relative to the feed rack 1, the pressing component 2 can pitch and swing around the transverse direction of the feed rack 1 as needed. This rotatable configuration allows the pressing component 2 to better adapt to pads and molding drums of different heights and shapes, enhancing the adaptability and flexibility of the equipment.

[0051] Furthermore, such as Figures 1 to 3As shown, the support 24 has an arc-shaped hole 240 at the end away from the feed rack 1, and the arc-shaped hole 240 extends along a preset arc-shaped trajectory. The pressing component 2 also includes a first fastener 25 and a second fastener 26. The first fastener 25 passes through the support 24 and is connected to the fixing plate 21, and the second fastener 26 passes through the arc-shaped hole 240 and is connected to the fixing plate 21. The second fastener 26 is movable along the extension direction of the arc-shaped hole 240 to adjust the position of the fixing plate 21 relative to the support 24. The first fastener 25 and the second fastener 26 are spaced apart. With this structural arrangement, the pitch angle of the pressing component can be precisely adjusted by the cooperation of the arc-shaped hole 240 and the two fasteners (i.e., the first fastener 25 and the second fastener 26). When the second fastener 26 slides along the preset arc-shaped trajectory, the fixing plate 21 rotates around the first fastener 25 as the axis, so that the pressure roller 22 can quickly adapt to the curvature of the forming drum. This design not only solves the problems of incomplete local pressing and uneven stretching of the adhesive pad caused by angular deviation in traditional pressing devices, but also significantly improves the uniformity of bonding and enhances adaptability to different drum diameters and material thicknesses. The spaced locking mechanism of the dual fasteners (i.e., the first fastener 25 and the second fastener 26) further ensures angular stability, effectively suppresses the offset caused by equipment vibration, and extends the life of the pressing components.

[0052] Optionally, when it is necessary to adjust the angular position of the fixing plate 21 relative to the bracket 24, the operation steps are as follows:

[0053] 1. Loosen fasteners: Loosen the first fastener 25 and the second fastener 26 on each bracket 24.

[0054] 2. Angle adjustment: Move the two second fasteners 26 along the extension direction of the arc-shaped hole 240. This movement causes the fixing plate 21 to rotate around the axis of the two first fasteners 25.

[0055] 3. Locking and fixing: After the two second fasteners 26 have moved to the target position, first tighten each second fastener 26 so that its top is pressed against the corresponding bracket 24. Then tighten each first fastener 25.

[0056] 4. Positioning completed: After the first fastener 25 and the second fastener 26 are locked, the fixing plate 21 is fixed relative to the two brackets 24.

[0057] In this configuration, the first fastener 25 on each bracket 24 is positioned opposite to each other, and the second fastener 26 on each bracket 24 is positioned opposite to each other.

[0058] Specifically, such as Figure 1 and Figure 2As shown, the padding pressing device includes: a telescopic component 3, which is disposed above the feeding rack 1. The telescopic rod 31 of the telescopic component 3 is arranged in the output direction of the feeding rack 1. Along the extension direction of the telescopic rod 31 of the telescopic component 3, the height of the output end of the telescopic rod 31 gradually increases. The output end of the telescopic rod 31 is hinged to the pressing component 2 so that the pressing component 2 can be moved by the extension and retraction of the telescopic rod 31.

[0059] Furthermore, such as Figure 1 and Figure 2 As shown, the output end of the telescopic rod 31 is hinged to the fixed plate 21, so that the fixed plate 21 can move by the extension and retraction of the telescopic rod 31. With this structural arrangement, the upward thrust of the telescopic rod, utilizing the hinged lever principle, efficiently converts the force into downward pressure on the fixed plate 21. This mechanical conversion mode can precisely control the magnitude and direction of the pressing pressure, ensuring that the pressure roller 22 acts smoothly on the forming drum and applies even and appropriate pressure to the padding, thereby improving the pressing quality. Simultaneously, the extension length of the telescopic rod 31 can be adjusted according to the thickness of the padding, thus enabling the pressing of padding of different thicknesses. This makes the equipment highly adaptable and can meet the pressing needs of various specifications of padding. Furthermore, the extension and retraction of the telescopic rod 31 are flexible, allowing for quick initiation of the pressing and release / reset process. This flexibility not only improves production efficiency but also reduces equipment waiting time, making the entire production process smoother.

[0060] Preferably, the telescopic component 3 is a cylinder.

[0061] Furthermore, such as Figure 1 and Figure 2 As shown, the padding pressing device also includes: a fixing frame 5, which extends in the transverse direction of the feeding frame 1, is installed on the feeding frame 1, is located at the top of the feeding frame 1, and is spaced apart from the pressing component 2 along the extension direction of the feeding frame 1. The body of the telescopic component 3 is connected to the fixing frame 5.

[0062] Furthermore, such as Figure 1 and Figure 2 As shown, the pressing component also includes a connecting plate 27, which is mounted on top of the fixed plate 21 and located at the center of the fixed plate 21. The fixed plate 21 is hinged to the output end of the telescopic rod 31 via the connecting plate 27.

[0063] Specifically, such as Figure 1 and Figure 2As shown, the padding pressing device also includes a contact frame 4, which is disposed at the output end of the feeding rack 1. Both ends of the contact frame 4 are fixedly connected to the feeding rack 1, and the contact frame 4 and the feeding rack 1 form a movable space. The pressing part of the pressing component is movably disposed within this movable space. With this structural arrangement, by setting the contact frame 4, the movable space enclosed by it and the feeding rack 1 not only provides a physical anti-collision barrier for the pressure roller 22 (avoiding accidental bumps and damage during production), but also prevents operators from accidentally entering the movable space, achieving dual protection for both the equipment and the operators.

[0064] Optionally, the working process of the adhesive pressing device is as follows:

[0065] As the padding material moves onto the feed rack 1, it advances towards the forming drum along the extension direction of the feed rack 1. Once the padding material is successfully attached to the forming drum, the telescopic rod 31 begins to extend. The connecting end of the telescopic rod 31 moves in an upward oblique direction.

[0066] As the telescopic rod 31 extends, it drives the fixed plate 21 through the hinge point, causing the fixed plate 21 to rotate downwards (pitch motion) around the lateral direction of the feeding frame 1. This, in turn, causes the bracket 24 to rotate relative to the feeding frame 1, thereby bringing each pressure roller 22 closer to the forming drum and pressing it onto the padding. As the forming drum rotates, each pressure roller 22 rotates synchronously, applying uniform pressure to the padding to ensure a tight fit between the padding and the forming drum.

[0067] After pressing is completed, the telescopic rod 31 retracts. At this time, the connecting end of the telescopic rod 31 moves in a downward direction. During the retraction process, the telescopic rod 31 drives the fixed plate 21 through the hinge point, causing the fixed plate 21 to rotate upward (pitch motion) around the transverse direction of the feeding frame 1, thereby moving each pressure roller 22 away from the forming drum.

[0068] This utility model also provides a padding material supply device, including: a padding pressing device, wherein the padding pressing device is the padding pressing device of the above embodiment.
