Description

Technical Field

[0001] This invention relates to the field of silent tire processing equipment technology, and in particular to a synchronous mechanism for attaching sound-absorbing foam to a silent tire and a working method thereof. Background Technology

[0002] Tire noise is generated by the friction between the tires and the road surface when a vehicle is traveling at high speed. The level of tire noise depends on the road and vehicle conditions; the worse the road conditions, the greater the tire noise. In addition, there is a significant difference in tire noise produced by asphalt roads and concrete roads. With the development of technology, some quiet tires have emerged. Quiet tires are tires with special sound-absorbing materials (such as sound-absorbing sponges) added inside the tire. They are designed to reduce cabin noise and improve driving comfort by absorbing the resonance caused by changes in air pressure between the tire and the rim.

[0003] The working principle of silent tires is relatively simple. When a car is moving, the internal air pressure between the tire and the rim constantly changes, generating resonance, which is the so-called cavity noise. This noise is usually between 150Hz and 250Hz, belonging to mid-frequency noise. Silent tires use a layer of sound-absorbing material attached to the inner wall of the tire. When vibrating air passes through the sound-absorbing foam inside the tire, friction is generated, thus attenuating the vibration and reducing the noise transmitted to the outside, thereby reducing the noise audible inside the car. When attaching the sound-absorbing foam to the inside of the tire, silent tires require sound-absorbing foam attachment equipment and tire positioning support equipment, as shown below.

[0004] A search revealed patent CN222244652U, which discloses a tire processing and fixing mechanism, belonging to the field of tire processing technology. The key technical features include an operating table with a support ring groove in the center. The support ring groove has a T-shaped cross-section, and a turntable is movably connected inside. The turntable has a clamping support mechanism in its center for fixing the inner and outer surfaces of the tire. This clamping support mechanism can clamp and fix the outer surface of the tire, facilitating processing of the inner surface. It can also support and fix the inner surface of the tire, facilitating processing of the outer surface. It can clamp and support tires of different sizes. A rotation drive mechanism can drive the turntable to rotate inside the support ring groove, facilitating the rotation and fixing of the tire. Thus, different methods can be used to fix the tire according to actual usage conditions, improving the convenience of tire processing.

[0005] However, as mentioned above, when existing tire positioning and support equipment limits and fixes the tire, the traditional limiting and fixing mechanism usually requires multiple cylinders or multiple motors to work, driving multiple outer clamps or inner support plates to limit and fix the tire. This results in high production costs, complex structures, and difficult control of the equipment. Furthermore, due to the large number of cylinders or motors, subsequent maintenance is also cumbersome and complicated, and the equipment has a high failure rate during daily operation. Therefore, there is an urgent need for a synchronous mechanism and working method for attaching sound-absorbing foam to silent tires to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention discloses a synchronous mechanism and its working method for attaching sound-absorbing foam to a silent tire. It comprises a conveying mechanism and a rotating support mechanism. During operation, an external conveying device transports the tire to the conveying mechanism, which further transports the tire until it reaches a work station. The conveying mechanism then pauses and lowers, moving the tire to a certain height. The rotating support mechanism then supports the tire, allowing for quick and convenient positioning and fixing. Since the rotating support mechanism only requires one first cylinder to simultaneously move four first inner support plates, providing inner ring support and fixing, it reduces production costs, has a simple structure, is easy to control, and is convenient for subsequent maintenance and has a low failure rate. In summary, it solves the problems in the prior art.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] The present invention provides a synchronous mechanism for attaching sound-absorbing sponge to a silent tire, comprising a bottom bracket, two side brackets fixedly connected to the top of the bottom bracket, a top bracket fixedly connected to the top of the two side brackets, and a sponge conveying and attaching mechanism connected to the top bracket.

[0009] A conveying mechanism located at the top of the bottom support;

[0010] A rotating support mechanism includes a base, a rotating seat, a rotating shaft, a sliding seat, and a first cylinder. The base is fixedly installed on the top of a bottom bracket. The rotating seat is located on the top of the base. The rotating shaft is located at the rotating seat. A gear is provided on the outside of the rotating shaft. Four sliding seats are provided, all of which are located on the top of the rotating seat. The sliding seats are connected to the gears via a transmission. An L-shaped first inner support plate is fixedly connected to the sliding seat. The first cylinder is fixedly installed on the top of the rotating seat via a mounting component. The telescopic end of the first cylinder is fixedly connected to the side of one of the first inner support plates. A support seat is mounted on the top of the rotating seat.

[0011] A movable seat mechanism, which is located between two side supports.

[0012] Furthermore, the rotating seat is rotatably mounted on the top of the base, and a first driving component is externally connected to the rotating seat. The first driving component is fixedly connected to the bottom bracket, and the rotating shaft is rotatably mounted on the rotating seat.

[0013] Furthermore, four slide rails are fixedly installed on the top of the rotating seat, and there are four slide seats. All four slide seats are slidably installed on the four slide rails, and each of the four slide seats has a transmission tooth plate on one side that meshes with a gear.

[0014] Furthermore, the top of the rotating seat is provided with multiple second cylinders, and the telescopic ends of the second cylinders are fixedly connected to a support seat. The support seat is provided with four sliding grooves, and the top ends of the four first inner support plates pass through the four sliding grooves respectively. The center of the support seat is provided with a first through groove.

[0015] Furthermore, the top of the rotating base is provided with multiple telescopic guide rods, the telescopic ends of which are fixedly connected to the bottom of the support base, and the top of the support base is provided with multiple through holes and ball bearings are installed thereon.

[0016] Furthermore, the conveying mechanism includes a mounting plate, a third cylinder, and a conveying frame. There are two mounting plates and two third cylinders. The two mounting plates are fixedly installed on the top of the bottom support. The two third cylinders are fixedly installed through the two mounting plates. The conveying frame is provided with two driving wheels and two driven wheels. The two driving wheels are fixedly connected by a connecting shaft. A second drive assembly is externally connected to the connecting shaft. A conveyor belt is provided between the two sets of driving wheels and driven wheels. The conveying frame is located above the support base, and the internal dimensions of the conveying frame are larger than the external dimensions of the support base.

[0017] Furthermore, two sets of movable guide rods are fixedly connected to the bottom of the conveyor frame, and the bottom ends of the movable guide rods all movably penetrate the bottom support.

[0018] Furthermore, the movable seat mechanism includes a top seat, which is slidably mounted between two side supports. The top of the top seat has a second through groove that matches the sponge conveying and attaching mechanism. A third drive assembly is mounted on the top of the top seat and is connected to the side supports in a transmission manner. Multiple pulleys are rotatably mounted on the bottom of the top seat. A fourth drive assembly is externally connected to the shaft end of one of the pulleys. The multiple pulleys are connected to each other by a transmission belt. Four L-shaped second inner support plates are slidably mounted on the bottom of the top seat. The second inner support plates are fixedly connected to the transmission belt by a fixing clamp.

[0019] A synchronous mechanism for attaching sound-absorbing foam to a silent tire, the working method of which includes the following steps:

[0020] S1. As described above, the mounting plate, the third cylinder, the conveyor frame, the driving wheel, the driven wheel, the connecting shaft, the second drive assembly, and the conveyor belt are assembled into a conveying mechanism. During operation, the external conveying device conveys the tire onto the two conveyor belts. The second drive assembly drives the connecting shaft to rotate, thereby driving the two driving wheels to rotate. In conjunction with the two driven wheels, the two conveyor belts are driven to operate, which can further convey the tire until the tire moves to the work station. The conveyor belt stops working, and the two third cylinders retract, causing the conveyor frame and the tire to move down.

[0021] S2. As described above, the base, rotating seat, rotating shaft, sliding seat, first cylinder, first drive assembly, gear, slide rail, second cylinder, support seat, and telescopic guide rod are assembled into a rotating support mechanism. During operation, after the tire moves down to a certain height, the conveyor frame continues to move down, and the support seat will support the tire. The four first inner support plates are located in the inner ring of the tire. When the first cylinder works, it drives one of the first inner support plates to move on the slide rail. When this first inner support plate moves, it will cooperate with the transmission gear plate on one side of the sliding seat to drive the gear to rotate. When the gear rotates, it can cooperate with the other three sliding seats and the transmission gear plate on one side to drive the other three first inner support plates to move synchronously. When all four first inner support plates have moved to the bottom of the inner ring of the tire and are engaged and pressed together, the tire can be fixed by inner support. Then the second cylinder works and cooperates with the telescopic guide rod to drive the support seat to move up a certain distance, thereby driving the tire to move up a certain distance, which is convenient for subsequent cooperation with the sponge conveying and attaching mechanism for silent sponge attaching work.

[0022] S3. As described above, the top seat, third drive assembly, pulley, fourth drive assembly, transmission belt, and second inner support plate are assembled with two side brackets to form a movable seat mechanism. During operation, after the tire is locked and fixed by the four first inner support plates, the tire can be moved upward a certain distance by the second cylinder. Then, the third drive assembly works to move the top seat downward until the four second inner support plates enter the inner ring of the tire. Subsequently, the fourth drive assembly works to rotate one of the pulleys, thereby driving the transmission belt pulley to rotate. When the transmission belt rotates, it can work with other pulleys and fixing clamps to synchronously drive multiple second inner support plates to move until all four second inner support plates have moved to the top of the inner ring of the tire and are locked and fixed. This allows for further inner support-type locking and fixing of the tire, further improving the tire's stability and preventing the tire from easily shaking and moving when applying sound-absorbing foam later, thus reducing the processing quality.

[0023] S4. As described above, after the tire is fixed in place, the first drive assembly operates, causing the rotating seat, support seat, and tire to rotate and adhere together with the sound-absorbing sponge. After the sound-absorbing sponge is attached to the tire, the fourth drive assembly operates first to release the upper and inner fixed positions of the tire. Then, the first cylinder operates to release the lower and inner fixed positions of the tire. Subsequently, the third drive assembly operates, causing the top seat to move upward and reset. Then, the two third cylinders extend, causing the conveyor frame to move upward. Together with the two conveyor belts, the tire is lifted to a suitable height again. Finally, the second drive assembly operates, causing the conveyor belt to start running again, sending away the tire after the sound-absorbing sponge is attached, and the processing of the next tire can begin again.

[0024] The present invention has the following advantages over the prior art:

[0025] 1. This technical solution incorporates a conveying mechanism and a rotating support mechanism. During operation, an external conveying device transports the tire to the conveying mechanism, which then further transports the tire until it reaches the workstation. The conveying mechanism then pauses and lowers, moving the tire to a certain height. The rotating support mechanism then supports the tire, allowing for quick and convenient positioning and fixing. Since the rotating support mechanism only requires one first cylinder to simultaneously move four first inner support plates, providing inner ring support and positioning for the tire, this reduces production costs. The structure is simple, easy to control, and requires minimal maintenance, with a low failure rate.

[0026] 2. This technical solution incorporates a movable seat mechanism. During operation, after the tire is secured and fixed by the four first inner support plates, the movable seat mechanism can move downwards until the four second inner support plates enter the inner ring of the tire. The four second inner support plates then move to the top of the inner ring of the tire and engage with it, further securing the tire with internal support. This improves the tire's stability and prevents the tire from easily shaking or moving when applying sound-absorbing foam, thus reducing processing quality.

[0027] 3. This technical solution incorporates a conveying mechanism, which allows the tire to be released from its limiting and fixing position after the sound-absorbing foam is applied to the tire. The conveying mechanism then moves upward and resets, lifting the tire to a suitable height. The tire with the sound-absorbing foam applied is then sent away, and the processing of the next tire can begin. Attached Figure Description

[0042] The conveying mechanism 7 is located on top of the bottom support 1; the rotating support mechanism 5 includes a base 501, a rotating seat 502, a rotating shaft 503, a slide 504, and a first cylinder 505.

[0043] The rotating seat 502 is rotatably mounted on the top of the base 501. The rotating seat 502 is externally connected to the first drive assembly 509, which is fixedly connected to the bottom bracket 1. The rotating shaft 503 is rotatably mounted on the rotating seat 502. Four slide rails 510 are fixedly mounted on the top of the rotating seat 502. There are four slide seats 504, which are slidably mounted on the four slide rails 510. Each of the four slide seats 504 has a transmission gear plate 516 on one side that meshes with a gear 506.

[0044] The top of the rotating seat 502 is provided with multiple second cylinders 511. The telescopic ends of the second cylinders 511 are fixedly connected to the support seat 508. The support seat 508 is provided with four sliding grooves 512. The top ends of the four first inner support plates 507 pass through the four sliding grooves 512 respectively. The center of the support seat 508 is provided with a first through groove 513. The top of the rotating seat 502 is provided with multiple telescopic guide rods 514. The telescopic ends of the telescopic guide rods 514 are fixedly connected to the bottom of the support seat 508. The top of the support seat 508 is provided with multiple through holes and ball bearings 515 are installed.

[0045] The conveying mechanism 7 includes a mounting plate 701, a third cylinder 702, and a conveying frame 703. Two mounting plates 701 and two third cylinders 702 are provided. Both mounting plates 701 are fixedly mounted on the top of the bottom support 1. Both third cylinders 702 are fixedly mounted through the two mounting plates 701. The conveying frame 703 has two driving wheels 704 and two driven wheels 705. The two driving wheels 704 are fixedly connected by a connecting shaft 706. A second drive assembly 707 is externally connected to the connecting shaft 706. A conveyor belt 708 is provided between each set of driving wheels 704 and driven wheels 705. The conveying frame 703 is located above the support base 508, and the internal dimensions of the conveying frame 703 are larger than the external dimensions of the support base 508. Two sets of movable guide rods 709 are fixedly connected to the bottom of the conveying frame 703, and the bottom ends of the movable guide rods 709 movably penetrate the bottom support 1.

[0046] The movable seat mechanism 6 includes a top seat 601, which is slidably mounted between two side supports 2. The top of the top seat 601 has a second through groove 602 that matches the sponge conveying and attaching mechanism 4. A third drive assembly 603 is mounted on the top of the top seat 601 and is connected to the side supports 2. Multiple pulleys 604 are rotatably mounted on the bottom of the top seat 601. A fourth drive assembly 605 is externally connected to the shaft end of one of the pulleys 604. The multiple pulleys 604 are connected to each other by a drive belt 606. Four L-shaped second inner support plates 607 are slidably mounted on the bottom of the top seat 601 and are fixedly connected to the drive belt 606 by a fixing clamp 608.

[0047] In the specific implementation process, during operation, the external conveying device transports the tire to the two conveyor belts 708. The second drive component 707 drives the connecting shaft 706 to rotate, thereby driving the two drive wheels 704 to rotate. In conjunction with the two driven wheels 705, the two conveyor belts 708 are driven to operate, which can further transport the tire until the tire moves to the work position. The conveyor belts 708 stop working, and the two third cylinders 702 work to retract, driving the conveyor frame 703 and the tire to move down.

[0048] After the tire moves down to a certain height, the conveyor frame 703 continues to move down, and the support seat 508 will support the tire. The four first inner support plates 507 are located in the inner ring of the tire, and the first cylinder 505 works, driving one of the first inner support plates 507 to move on the slide rail 510. When this first inner support plate 507 moves, it will cooperate with the transmission tooth plate 516 on one side of the slide 504 to drive the gear 506 to rotate. When the gear 506 rotates, it can cooperate with the other three slides 504 and the transmission tooth plate 516 on one side to drive the other three first inner support plates 507 to move synchronously. When all four first inner support plates 507 have moved to the bottom of the inner ring of the tire and are engaged and pressed, the tire can be fixed by inner support. Then the second cylinder 511 works, and in cooperation with the telescopic guide rod 514, it drives the support seat 508 to move up a certain distance, thereby driving the tire to move up a certain distance, which is convenient for subsequent cooperation with the sponge conveying and attaching mechanism 4 to perform the silent sponge attaching work.

[0049] After the tire is secured and fixed by the four first inner support plates 507, the second cylinder 511 can move the tire upward a certain distance. Then, the third drive assembly 603 works, moving the top seat 601 downward until the four second inner support plates 607 enter the inner ring of the tire. Subsequently, the fourth drive assembly 605 works, driving one of the pulleys 604 to rotate, thereby driving the transmission belt 606 to rotate. When the transmission belt 606 rotates, it can work with the other pulleys 604 and the fixing clamp 608 to move the multiple second inner support plates 607 synchronously until all four second inner support plates 607 have moved to be secured and fixed at the top of the inner ring of the tire. This further improves the stability of the tire and prevents the tire from easily shaking and moving when applying the sound-absorbing foam, thus reducing the processing quality.

[0050] The first drive component 509 is used to drive the rotating seat 502 to rotate, so that it can cooperate with the support seat 508 to drive the tire to rotate, which facilitates the subsequent work of attaching the tire with the sponge conveying and attaching mechanism 4.

[0051] The telescopic guide rod 514 is used to improve the overall stability of the support seat 508 and prevent the support seat 508 from shaking easily, thereby improving the overall stability of the tire. The ball bearing 515 is used to facilitate the adjustment and movement of the tire on the support seat 508.

[0052] The movable guide rod 709 is designed to improve the overall stability of the conveyor frame 703 and prevent the conveyor frame 703 from shaking easily, thereby effectively preventing the tire from slipping off the conveyor frame 703.

[0053] Working principle: During operation, the tire is transported to the conveyor frame 703 by an external conveying device. The conveyor belt 708 at the conveyor frame 703 moves the tire to the work station. Then the conveyor frame 703 moves down, driving the tire down until the tire moves down to the bottom and contacts the top of the support seat 508. The support seat 508 provides support for the tire. The conveyor frame 703 continues to move down a certain distance to avoid affecting the subsequent rotation of the tire driven by the support seat 508.

[0054] Once the tire is positioned on the support seat 508, the four first inner support plates 507 move to fasten and tighten the inner ring of the tire from the inside out, thereby limiting and fixing the tire. The support seat 508 can also move upwards a certain distance to avoid obstruction during rotation. Then, the top seat 601 moves downwards, and the four second inner support plates 607 move to further fasten and tighten the inner ring of the tire from the inside out, improving the limiting and fixing effect of the tire. When the sponge conveying and attaching mechanism 4 moves and inserts the sound-absorbing sponge into the tire, the first drive component 509 operates, driving the rotating seat 502 to rotate, thereby driving the support seat 508 and the tire to rotate, performing the attaching work of the sound-absorbing sponge. While the sponge conveying and attaching mechanism 4 is moving and conveying the sound-absorbing sponge, the equipment will simultaneously convey, move downwards, perform initial limiting and fixing, move upwards, and further limit and fix the tire, improving work efficiency.

[0055] After the sound-absorbing foam is attached to the tire, the first inner support plate 507 and the second inner support plate 607 are reset, releasing the tire from its limiting and fixing position. The foam conveying and attaching mechanism 4 and the top seat 601 are also reset. Then, the support seat 508 moves down and the conveyor frame 703 moves up, lifting the tire again. The tire is then discharged through the conveyor belt 708, and the processing of the next tire can begin again.

[0056] A synchronous mechanism for attaching sound-absorbing foam to a silent tire, the working method of which includes the following steps:

[0057] S1. As described above, the mounting plate 701, the third cylinder 702, the conveyor frame 703, the drive wheel 704, the driven wheel 705, the connecting shaft 706, the second drive assembly 707, and the conveyor belt 708 are assembled into a conveying mechanism 7. During operation, the tire is conveyed to the two conveyor belts 708 by an external conveying device. The second drive assembly 707 drives the connecting shaft 706 to rotate, thereby driving the two drive wheels 704 to rotate. In conjunction with the two driven wheels 705, the two conveyor belts 708 are driven to operate, which can further convey the tire until the tire moves to the work station. The conveyor belt 708 stops working, and the two third cylinders 702 work to retract, driving the conveyor frame 703 and the tire to move down.

[0058] S2. As described above, the base 501, rotating seat 502, rotating shaft 503, sliding seat 504, first cylinder 505, first drive assembly 509, gear 506, slide rail 510, second cylinder 511, support seat 508, and telescopic guide rod 514 are assembled into a rotating support mechanism 5. During operation, after the tire descends to a certain height, the conveyor frame 703 continues to descend, and the support seat 508 provides support for the tire. Four first inner support plates 507 are located within the inner ring of the tire, and the first cylinder 505 operates, causing one of the first inner support plates 507 to move on the slide rail 510. This first inner support plate 507 moves... When the transmission gear plate 516 on one side of the slide 504 is engaged, it will drive the gear 506 to rotate. When the gear 506 rotates, it can work with the other three slides 504 and the transmission gear plate 516 on one side to drive the other three first inner support plates 507 to move synchronously. When all four first inner support plates 507 have moved to the bottom of the inner ring of the tire and are engaged and pressed together, the tire can be fixed by inner support. Then the second cylinder 511 works and works with the telescopic guide rod 514 to drive the support seat 508 to move up a certain distance, thereby driving the tire to move up a certain distance, which is convenient for subsequent work with the sponge conveying and attaching mechanism 4 to attach the silent sponge.

[0059] S3. As described above, the top seat 601, the third drive assembly 603, the pulley 604, the fourth drive assembly 605, the transmission belt 606, and the second inner support plate 607 are assembled with the two side brackets 2 to form a movable seat mechanism 6. During operation, after the tire is secured by the four first inner support plates 507, the second cylinder 511 can move the tire upwards a certain distance. Then, the third drive assembly 603 operates, moving the top seat 601 downwards until the four second inner support plates 607 enter the inner ring of the tire. Subsequently, the fourth... When the drive assembly 605 is working, it drives one of the pulleys 604 to rotate, which in turn drives the transmission belt 606 to rotate. When the transmission belt 606 rotates, it can work with multiple other pulleys 604 and fixing clamps 608 to synchronously drive multiple second inner support plates 607 to move until all four second inner support plates 607 have moved to engage and abut against the top of the inner ring of the tire. This allows for further inner support-type limiting and fixing of the tire, further improving the tire's stability and preventing the tire from easily shaking or moving when applying sound-absorbing foam later, thus reducing the processing quality.

[0060] S4. As described above, after the tire is fixed in place, the first drive assembly 509 operates, causing the rotating seat 502, support seat 508, and tire to rotate and adhere together with the sound-absorbing sponge. After the sound-absorbing sponge is attached to the tire, the fourth drive assembly 605 operates first to release the upper and inner fixed positions of the tire. Then, the first cylinder 505 operates to release the lower and inner fixed positions of the tire. Subsequently, the third drive assembly 603 operates, causing the top seat 601 to move upward and reset. Then, the two third cylinders 702 operate and extend, causing the conveyor frame 703 to move upward. Together with the two conveyor belts 708, the tire is lifted to a suitable height again. Finally, the second drive assembly 707 operates, causing the conveyor belt 708 to start running again, sending away the tire after the sound-absorbing sponge is attached, and the processing of the next tire can begin again.

9. The working method of the synchronous mechanism for attaching sound-absorbing foam to a silent tire as described in any one of claims 1-8, characterized in that: Includes the following steps; S1. As described above, the mounting plate (701), the third cylinder (702), the conveyor frame (703), the drive wheel (704), the driven wheel (705), the connecting shaft (706), the second drive assembly (707), and the conveyor belt (708) are assembled into a conveying mechanism (7). During operation, the tire is conveyed to the two conveyor belts (708) by an external conveying device. The second drive assembly (707) drives the connecting shaft (706) to rotate, thereby driving the two drive wheels (704) to rotate. In conjunction with the two driven wheels (705), the two conveyor belts (708) are driven to run, which can further convey the tire until the tire moves to the work station. The conveyor belt (708) stops working, and the two third cylinders (702) work to retract, driving the conveyor frame (703) and the tire to move down. S2. As described above, the base (501), rotating seat (502), rotating shaft (503), sliding seat (504), first cylinder (505), first drive assembly (509), gear (506), slide rail (510), second cylinder (511), support seat (508), and telescopic guide rod (514) are assembled into a rotating support mechanism (5). During operation, when the tire moves down to a certain height, the conveyor frame (703) continues to move down, and the support seat (508) will support the tire. The four first inner support plates (507) are located in the inner ring of the tire, and the first cylinder (505) works, driving one of the first inner support plates (507) to move on the slide rail (510). (507) When moving, it will cooperate with the transmission tooth plate (516) on one side of the slide (504) to drive the gear (506) to rotate. When the gear (506) rotates, it can cooperate with the other three slides (504) and the transmission tooth plate 516 on one side to drive the other three first inner support plates (507) to move synchronously. When all four first inner support plates (507) move to the bottom of the inner ring of the tire and are fastened together, the tire can be fixed by the inner support type. Then the second cylinder (511) works and cooperates with the telescopic guide rod (514) to drive the support seat (508) to move up a certain distance, thereby driving the tire to move up a certain distance, which is convenient for subsequent cooperation with the sponge conveying and attaching mechanism (4) to carry out the silent sponge attaching work. S3. As described above, the top seat (601), the third drive assembly (603), the pulley (604), the fourth drive assembly (605), the transmission belt (606), and the second inner support plate (607) are assembled with two side brackets (2) to form a movable seat mechanism (6). During operation, after the tire is secured by the four first inner support plates (507), the second cylinder (511) can drive the tire to move up a certain distance. Then, the third drive assembly (603) works to drive the top seat (601) to move down until the four second inner support plates (607) enter the inner ring of the tire. Then the fourth drive assembly (605) works, driving one of the pulleys (604) to rotate, thereby driving the transmission belt (606) pulley to rotate. When the transmission belt (606) rotates, it can work with other pulleys (604) and fixing clamps (608) to synchronously drive multiple second inner support plates (607) to move until all four second inner support plates (607) have moved to the top of the inner ring of the tire and are fastened together. Then the tire can be further internally supported and fixed, which further improves the stability of the tire and prevents the tire from easily shaking and moving when the sound-absorbing sponge is attached later, thus reducing the processing quality. S4. As described above, after the tire is fixed in place, the first drive assembly (509) works, driving the rotating seat (502), support seat (508) and tire to rotate and adhere together with the sound-absorbing sponge. After the sound-absorbing sponge is attached to the tire, the fourth drive assembly (605) works first to release the upper and inner fixed positions of the tire. Then the first cylinder (505) works to release the lower and inner fixed positions of the tire. Subsequently, the third drive assembly (603) works to move the top seat (601) up and reset. Then the two third cylinders (702) work to extend and move the conveyor frame (703) up. Together with the two conveyor belts (708), the tire is lifted to a suitable height again. Finally, the second drive assembly (707) works to drive the conveyor belt (708) to start running again and send the tire after the sound-absorbing sponge is attached away, and the processing of the next tire can start again.
