Description

Technical Field

[0001] This invention relates to the field of tire conveying technology, and more particularly to a tire conveying device. Background Technology

[0002] In the tire manufacturing industry chain, from cooling and transportation after vulcanization to long-term storage in the warehousing process, the stability of the conveying and storage system directly determines the final quality and production efficiency of the tire. With the continuous improvement of the automotive industry's requirements for tire precision and the increase in the demand for flexible production of multi-specification tires, traditional tire conveying and storage equipment has gradually exposed multi-dimensional technical defects and can no longer adapt to modern production scenarios.

[0003] Existing equipment mostly uses a flatbed load-bearing mode to transport tires, transmitting power only through the contact between the tire tread or sidewall and the transport component. The inner side of the tire bead is in a state of no support for a long time. During the transport process, the tire bead is prone to deformation due to its own weight, which leads to insufficient air tightness during subsequent wheel assembly. Summary of the Invention

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0031] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figures 1 to 9As shown, this application proposes a tire conveying device, including a conveyor frame 101 and a conveyor motor 103, the conveyor motor 103 being fixed on the conveyor frame 101; it also includes a conveying assembly 200; the conveying assembly 200 is fixed on the conveyor frame 101, and includes a conveyor belt 201, a placement plate 202, a support rod 204, a support frame 205, and a storage box 206; the conveyor belt 201 is fixed on the conveyor frame 101, and the conveyor belt 201 consists of two annular belts, the conveyor belt 201 being driven by the conveyor motor 103, and the tires are moved forward on the conveyor frame 101 through the conveyor belt 201; the support rod 204 is fixed on the adjacent sidewalls of the two annular belts, and the placement plate 202 is fixed on the support frame 106. At the center of the support rod 204, a circular rubber plate 202 is placed to hold the tire. The support frame 205 is stored in a storage box 206, which is fixed to the conveyor frame 101 and located below the conveyor belt 201. The placement plate 202 includes a fixing plate 2021, an air connector 2022, a quick-release connector 2026, and a support bladder 2023. When the fixing plate 2021 rotates with the conveyor belt 201 above the storage box 206, the support frame 205 and the fixing plate 2021 are fixed together by the quick-release connector 2026, which is fixed to the adjacent side walls of the fixing plate 2021 and the support frame 205. The air connector 2022... 022 and support bladder 2023 are respectively fixed on fixed plate 2021. Air connector 2022 is connected to support bladder 2023 through air pipe 211. When placement plate 202 rotates above storage box 206, air connector 2022 on fixed plate 2021 and air connector 2022 on support frame 205 are connected. At the same time, quick-release connector 2026 on fixed plate 2021 and quick-release connector 2026 on support frame 205 are fixedly connected together, so that support frame 205 is moved out of storage box 206 and moves with placement plate 202. When placement plate 202 with support frame 205 moves to the upper side of conveyor belt 201, tire is placed on placement plate 202. Support bladder 2023 consists of two halves. The circular hollow capsule 2023 contains a spring that allows it to regain its shape when the tire is removed. The support capsule 2023 is located on both sides of the air inlet connector 2022. When the tire is placed on the placement plate 202, the tire sidewall comes into contact with the support capsule 2023. The support capsule 2023 can be compressed and deformed by the tire, allowing the gas inside the support capsule 2023 to enter the support frame 205 through the air inlet pipe 211. Multiple arc-shaped capsules are fixed on the support frame 205 and distributed around the air inlet connector 2022. The air entering the support frame 205 can cause the arc-shaped capsules to expand. After expansion, the arc-shaped capsules can come into contact with the tire bead, thereby preventing the tire bead from deforming due to lack of support during transportation and storage.

[0034] Preferably, an adjusting motor 104 is fixed on the conveyor frame 101, and a screw is fixed on the rotating shaft of the adjusting motor 104. One of the annular belts of the conveyor belt 201 is fixed on the sliding frame 105. The sliding frame 105 is fixed on the conveyor frame 101 in a sliding connection manner. The screw passes through the sliding frame 105 and is threadedly connected to the sliding frame 105. The adjusting motor 104 drives the sliding frame 105 to move toward or away from the other annular belt, thereby adjusting the distance between the two annular belts according to the diameter of the conveyor tire.

[0035] Preferably, the fixing plate 2021 has multiple rectangular grooves, and the support rod 204 is slidably and fixedly connected in the rectangular grooves. The support rod 204 is a plurality of rectangular rods. When the distance between the conveyor belts 201 changes, the support rods 204 can slide into the rectangular grooves on the fixing plate 2021 at the same time.

[0036] Preferred, such as Figure 9 As shown, the support bladder 2023 is fixed on the connecting plate 2025, which is a circular plate. The connecting plate 2025 is fixed to the bottom of the fixing plate 2021. The support bladder 2023 has multiple diameters and is a semi-circular hollow bladder made of elastic rubber. The support bladder 2023 is a whole unit. The diameter of the support bladder 2023 is set according to the diameter of the tire to be transported. The support bladders 2023 are attached to each other and connected by an air supply pipe 211. A one-way valve 2024 is provided between the attached support bladders 2023 so that when the support bladder 2023 is deformed by pressure, air is squeezed into the support frame 205, preventing air from being squeezed into adjacent support bladders 2023. When the tire is placed on the fixing plate 2021, the support bladders 2023 with the same diameter can be compressed and deformed. The support bladders 2023 located on the outside of the tire maintain their original shape and can contact the tire tread, which can prevent the tire tread from being scratched or damaged during the tire transport process.

[0037] Preferred, such as Figure 5 As shown, the storage box 206 is a rectangular box with an open top. The support frame 205 is stacked inside the storage box 206. A spring plate is fixed to the bottom of the storage box 206. A rectangular rod is fixed to the top opening of the storage box 206 to restrict the support frame 205 inside the storage box 206. The spring plate at the bottom of the storage box 206 ensures that the support frame 205 inside the box always abuts against the rectangular rod at the top of the storage box 206. A groove is provided on one side wall of the storage box 206 to facilitate the removal of the uppermost support frame 205 from the box.

[0038] Preferably, the storage box 206 has a rotating door panel on its side wall, which makes it convenient to place the support frame 205 inside the storage box 206 when the support frame 205 is no longer needed.

[0039] Preferably, the support bladder 2023 and the connecting plate 2025 are fixed together by a quick-release connector 2026, which makes it easy to remove the support bladder 2023 from the placement plate 202 and to install a support bladder 2023 of appropriate diameter according to the diameter of the conveying tire.

[0040] Preferably, the bottom of the conveyor frame 101 is fixed with a movable wheel 102, which is driven by a motor, so that the conveyor frame 101 can be moved to the shelf next to different storage tires.

[0041] Preferred, such as Figure 8 As shown, a fixed frame 106 is fixed on the conveyor frame 101. The fixed frame 106 is fixed to the conveyor frame 101 by bolts. One of the annular belts of the conveyor belt 201 is fixed to the fixed frame 106. The conveyor motor 103 is fixed to the side wall of the fixed frame 106. The conveyor motor 103 drives the other annular belt to rotate through a rotating shaft. Multiple support plates 203 are fixed to the fixed frame 106 and the sliding frame 105 by bolts. The support plates 203 are Z-shaped metal plates. The top of the support plates 203 can contact the conveyor belt 201. Support rollers 2031 are fixed to the contact part between the support plates 203 and the conveyor belt 201. The support rollers 2031 are rubber rollers. The support rollers 2031 can support the conveyor belt 201 and prevent the conveyor belt 201 from deforming due to the weight of the tires.

[0042] Preferably, the conveyor belt 201 is a rubber belt with a steel wire rope core, which enables the conveyor belt 201 to bear the weight of multiple tires.

[0043] Preferably, the support frame 205 consists of a cross-shaped metal rod 218 and an arc-shaped bladder 216 fixed to the end of the metal rod 218. Four arc-shaped bladders 216 are provided, forming a ring. The air inlet connector 2022 is fixed at the center of the metal rod 218. An airflow channel is provided inside the metal rod 218. The arc-shaped bladders 216 are fixed to the end of the metal rod 218 via corrugated pipes. When the tire compresses the air in the support bladder 2023 into the support frame 205... At 5 o'clock, air is first compressed into the bellows, which causes the arc-shaped bladder 216 to move toward the inside of the tire. When the arc-shaped bladder 216 extends into the inside of the rim, the bellows extends to its longest state. Then, the air entering the support frame 205 causes the arc-shaped bladder 216 to expand, thereby making the arc-shaped bladder 216 contact the rim. An arc-shaped groove is provided on the contact surface between the arc-shaped bladder 216 and the rim. When the arc-shaped bladder 216 expands, the edge of the rim can be stuck in the arc-shaped groove, thereby preventing the arc-shaped bladder 216 from falling out of the tire after expansion.

[0044] Preferably, a one-way valve 2024 is provided at the connection between the bellows and the metal rod 218 to prevent air from leaking out of the arc-shaped bladder 216.

[0045] Preferably, a control panel is also installed on the side wall of the conveyor frame 101. The control panel is equipped with multiple operation buttons, which are used to control the start and stop of components such as the conveyor motor 103 and the regulating motor 104, and to adjust the operating parameters.

[0046] Preferably, the conveyor belt 201 is provided with 6 to 8 placement plates 202.

[0047] Preferably, the side of the conveyor frame 101 is also provided with two gratings for detecting the tire position and the position of the placement plate 202. The gratings are connected to the control system that controls the conveyor motor 103, the adjusting motor 104 and other components. The gratings are located at the position where the tire is placed and can detect whether a tire is placed on the placement plate 202.

[0048] In actual use, a tire conveying device according to an embodiment of this application is as follows: First, the conveyor belt 201 is driven to rotate by the conveyor motor 103, causing the placement plate 202 fixed on the conveyor belt 201 to move along with the conveyor belt 201. When the placement plate 202 on the conveyor belt 201 moves above the storage box 206, the quick-release connector 2026 on the fixed plate 2021 and the quick-release connector 2026 on the support frame 205 are fixed together. At the same time, the air supply connector 2022 on the fixed plate 2021 and the air supply connector 2022 on the support frame 205 are connected together, so that the support frame 205 is fixed on the fixed plate 2021. The support frame 205 fixed on the fixed plate 2021 moves along with the conveyor belt 201. 1. Move to the position on the upper side of the conveyor frame 101 to place the tire. The grating fixed on the side of the conveyor frame 101 can detect the position of the placement plate 202. Since the tire is not placed, the conveyor motor 103 stops running at this time, so that the placement plate 202 stops at the position where the tire is placed. Then the tire is picked up by the robot and placed on the placement plate 202. After the grating detects that the tire is placed, the conveyor motor 103 continues to run, so that the placement plate 202 with the tire moves towards the storage rack 302. When the next placement plate 202 moves to the position where the tire is placed, the grating detects that the tire is not placed and controls the conveyor motor 103 to stop running again. Then, under the weight of the tire, the support bladder 2023 on the placement plate 202 is compressed and deformed, causing the air inside the support bladder 2023 to be squeezed into the support frame 205 through the air inlet connector 2022. The air entering the support frame 205 first enters the bellows at the end of the metal rod 218, causing it to expand towards the tire. When the tire is placed on the placement plate 202, the arc-shaped bladder 216 is already in a position with only a few millimeters of gap between it and the rim. The expansion of the bellows causes the arc-shaped bladder 216 to move towards the inside of the tire. When the bellows expands to its longest state, the tire... The tire bead can be stuck in the arc groove on the support bladder 2023. The air inside the support bladder 2023 is further compressed into the arc bladder 216, causing the arc bladder 216 on the support frame 205 to expand. The arc bladder 216 expands until it contacts the rim of the tire and the edge of the tire bead is stuck in the arc groove. Thus, the rim of the tire is supported by the support frame 205 during the transportation process. Finally, the placement plate 202 with the tire moves from one end of the conveyor frame 101 to the other end. Finally, the robot arm removes the tire from the placement plate 202 and places it on the tire storage rack.

[0049] In some embodiments of the present invention, considering that when conveying large tires, due to the large weight of the tires, when multiple tires are placed on the placement plate 202 simultaneously, the conveyor belt 201 may break due to its inability to bear the weight of the tires, and that after the tires have undergone vulcanization, trimming, grinding, and other pre-processing, the tire surface may have residual rubber burrs and debris that have not been cleaned properly. These debris may fall off during conveying and adhere to the placement plate 202. Because the contact area between these foreign objects and the tire is extremely small, a large pressure is formed at the contact point, resulting in pressure-induced scratches on the tire rubber layer. To address the above problems, further improvements have been made, specifically: Specifically, such as Figures 10 to 14 As shown, the conveying assembly 200 also includes an annular rack 207, a support wheel 208, a moving motor 209, a nozzle 210, an air delivery pipe 211, and a cleaning bladder 215; The conveyor belt 201 is a metal ring with grooves on its sidewalls. A ring-shaped rack 207 is fixed within the grooves. A gear meshing with the rack is fixed to the end of the support rod 204. A moving motor 209 is fixed inside the support rod 204, driving the gear to rotate and causing the support rod 204 to move within the grooves on the conveyor belt 201. Multiple cleaning bags 215, which are hollow air bags, are fixed within the grooves on the conveyor belt 201. A support wheel 208, capable of rolling within the grooves of the conveyor belt 201, is fixed to the support rod 204. The support wheel 208 is located on one side of the ring-shaped rack 207 and can... During the movement, the cleaning bladder 215 is squeezed. The cleaning bladder 215 is connected to the nozzle through the air supply pipe 211. The air supply pipe 211 is set on the conveyor frame 101 and fixed to the lower side of the conveyor belt 201. Multiple nozzles are set at an angle with the air outlets of the nozzles facing the conveyor belt 201. As the support rod 204 moves on the conveyor belt 201, it continuously squeezes the cleaning bladder 215, causing the airflow in the cleaning bladder 215 to be sprayed from the nozzles onto the conveyor belt 201, blowing off foreign objects attached to the conveyor belt 201 and the placement plate 202. This prevents foreign objects from adhering to the placement plate 202 during the tire transport process, thus avoiding scratches on the tires caused by foreign objects.

[0050] Preferably, the cleaning bladder 215 is a semi-circular hollow bladder, and the cleaning bladder 215 is an elastic rubber bladder made of wear-resistant material. The cleaning bladder 215 is connected to the air supply pipe 211 by a copper connector. The connector passes through the conveyor belt 201 and fixes the cleaning bladder 215 from the other side of the conveyor belt 201, which facilitates the removal and replacement of the cleaning bladder 215.

[0051] Preferably, the fixed frame 106 and the sliding frame 105 are fixed to the conveyor frame 101 by bolts, which facilitates the removal and replacement of the conveyor assembly 200 from the conveyor frame 101.

[0052] Preferred, such as Figure 15 As shown, three cylindrical rods connected together by rectangular plates form a set of support rods 204. The rectangular plates fix the three cylindrical rods together in pairs and allow them to rotate relative to each other. When the support rods 204 move to the arc-shaped parts at both ends of the conveyor belt 201, the relative rotation between the support rods 204 can prevent the support rods 204 from getting stuck in the conveyor belt 201. The moving motor 209 is fixed on the cylindrical rod located in the middle position. Gears that mesh with the annular rack 207 are fixed on the cylindrical rods located on both sides. During the movement of the support rods 204, the gears roll on the annular rack 207.

[0053] Preferably, both the quick-release connector 2026 and the gas supply connector 2022 are ball-type quick-release connectors, which can ensure the stability and sealing of the connectors during connection and effectively prevent gas leakage.

[0054] Preferred, such as Figure 14As shown, the gas supply pipe 211 consists of two sections of copper pipe. The two sections of gas supply pipe 211 are connected by a connecting pipe 217. When adjusting the distance between the two conveyor belts 201, the two sections of gas supply pipe 211 can slide within the connecting pipe 217, thereby adjusting the length of the gas supply pipe 211.

[0055] Preferably, the two gas supply pipes 211 connected by the connecting pipe 217 are of different lengths. Each set of gas supply pipes 211 connected by the connecting pipe 217 consists of one long and one short pipe, and the adjacent gas supply pipes 211 are also of different lengths. This makes the nozzles located at the bottom of the conveyor frame 101 staggered, avoiding the existence of dead corners that cannot be cleaned in the gaps between adjacent nozzles, and ensuring that no foreign objects remain on the placement plate 202.

[0056] Preferably, the cleaning bag 215 and the conveyor belt 201 are detachably connected by Velcro or buckles, which allows for convenient and quick operation when the cleaning bag 215 is damaged or needs to be replaced.

[0057] Preferably, the distance between the nozzle and the placement plate 202 is 10cm to 20cm, which ensures that the airflow from the nozzle has sufficient force to blow away foreign objects. The angle between the nozzle and the placement plate 202 is 30° to 60°, which can blow out foreign objects stuck in the gap of the support bladder 2023, thereby improving the cleaning effect. In addition, a collection box is provided at the bottom of the conveyor frame 101 to collect foreign objects such as rubber flash and debris blown away by the nozzle.

[0058] In actual use, based on the above embodiments, firstly, under the drive of the moving motor 209, the support rod 204 moves in the groove of the conveyor belt 201. During the movement of the support rod 204, the moving motor 209 on the cylindrical rod located in the middle position continues to work, driving the gear to roll on the ring rack 207, ensuring that the support rod 204 moves stably. When the support rod 204 moves to the arc-shaped portions at both ends of the conveyor belt 201, the support rod 204, composed of three cylindrical rods connected by a rectangular plate, is fixed in pairs by the rectangular plate and can rotate relative to each other. This allows the support rods 204 to rotate relative to each other, successfully preventing them from getting stuck in the conveyor belt 201. The support rod 204 drives the placement plate 202 to move on the annular conveyor belt 201. Simultaneously, the support wheel 208 on the support rod 204 continuously squeezes the cleaning bladder 215. Since the cleaning bladder 215 is an elastic rubber bladder, after being squeezed, the internal airflow quickly flows through the air pipe 211 to the nozzles, causing the airflow to be ejected simultaneously from multiple inclined nozzles. The nozzle 210 of the nozzle has an hourglass-shaped cross-section, which increases the airflow speed when it exits the nozzle 210. This airflow can then be blown towards the conveyor belt 201 and the placement plate 202, removing the air adhering to them. The system blows away rubber burrs, debris, and other foreign objects, achieving automatic cleaning of the conveyor belt 201 and placement plate 202 during tire transport. This effectively avoids tire scratches caused by foreign objects adhering to the tires. Simultaneously, the air supply pipe 211 consists of two copper pipes connected by a connecting pipe 217. When adjusting the distance between the two conveyor belts 201, the two air supply pipes 211 slide within the connecting pipe 217, automatically adjusting their length. Each set of air supply pipes 211 has one long and one short pipe, and adjacent air supply pipes 211 also have different lengths, resulting in staggered nozzle distribution at the bottom of the conveyor frame 101, preventing cleaning dead zones. Foreign objects blown off by the nozzles fall into a collection box at the bottom of the conveyor frame 101, completing the cleaning process. When a cleaning bag 215 is damaged or needs replacement, it can be separated from the conveyor belt 201 using Velcro or clips, and a new cleaning bag 215 can be installed.

[0059] In some embodiments of the present invention, considering that the conveying equipment transports tires in batches, and each batch of tires has the same diameter, if the diameter difference between the tires transported in the previous batch and the tires transported in the next batch is too large, the support bladder 2023 on the placement plate 202 needs to be replaced. Otherwise, when the next batch of tires is placed on the placement plate 202, it may not be able to contact the support bladder 2023, causing the arc-shaped bladder 216 on the support frame 205 to fail to support the tire rim. Since there are multiple placement plates 202 on the conveyor belt 201, and each placement plate 202 is fixed with a set of support bladders 2023, even if the support bladders 2023 are fixed to the placement plate 202 by quick-release connectors 2026, if the workers manually disassemble and replace them, the process is not only complicated but also time-consuming. To address the above problems, further improvements have been made, specifically: Specifically, such as Figure 13 As shown, a fixed rod 212 is fixed on the conveyor frame 101, and multiple rotating rods 214 are rotatably connected to the fixed rod 212. The rotating rods 214 are rectangular rods and can rotate around the fixed rod 212. The rotating rods 214 are located on the upper side of the placement plate 202. A connector 213 is fixed on the rotating rod 214. The connector 213 is a cylindrical rod. A connecting ring 2027 is fixed on the upper side of the support bag 2023. The connecting ring 2027 is an elastic rubber plate with a circular hole. The connector 213 can... The connector 213 can cooperate with the connecting ring 2027 on the support bladder 2023. During the movement of the placement plate 202, the connector 213 can extend into the connecting ring 2027. Using the pulling force generated when the placement plate 202 moves, the support bladder 2023 can be removed from the placement plate 202 and hung on the rotating rod 214. The staff can then remove the support bladder 2023. After the conveyor belt 201 rotates once, the support bladder 2023 fixed on the placement plate 202 can be completely removed.

[0060] Preferably, four sets of rotating rods 214 are fixed on the fixed rod 212, with adjacent rotating rods 214 spaced 90° apart. The rotating rods 214 are driven to rotate by a motor located inside the fixed rod 212. The motor is a servo motor, which can determine whether the support bag 2023 is hanging on the rotating rod 214 based on torque changes, and rotate the rotating rod 214 with the support bag 2023 hanging on it to the upper side, so that the staff can easily remove the support bag 2023. At the same time, the rotating rod 214 without the support bag 2023 hanging on it is rotated to a position flush with the surface of the placement plate 202. When the placement plate 202 moves forward, the connector 213 on the rotating rod 214 can just extend into the connecting ring 2027 on the support bag 2023.

[0061] Preferably, the bottom of the fixed rod 212 is fixed to the fixed frame 106 and the sliding frame 105 by bolts respectively. The fixed rod 212 is composed of two inverted L-shaped rods slidably connected. The rotating rod 214 is rotatably connected to the horizontal part of one of the L-shaped rods. When the distance between the conveyor belts 201 is adjusted, the sliding frame 105 slides on the conveyor frame 101, and one of the L-shaped rods can slide inside the other L-shaped rod, so that the rotating rod 214 is always directly above the placement plate 202.

[0062] Preferably, the connector 213 is a hard rubber rod, which can withstand the pulling force generated when the support bladder 2023 is disassembled, and is not easily deformed or damaged, ensuring that the connector 213 can be stably used with the connecting ring 2027 multiple times. The surface of the connector 213 is smoothed to avoid damaging the support bladder 2023. The part of the connector 213 that extends into the connecting ring 2027 is conical, and its diameter gradually decreases from the end near the rotating rod 214 to the end, which facilitates the smooth insertion of the connector 213 into the connecting ring 2027, and after insertion, it can form a tight fit with the connecting ring 2027 to prevent the connector 213 from falling out of the connecting ring 2027 during disassembly.

[0063] Preferably, the conveying roller 303 is fixed with sprockets at both ends. The conveying roller 303 rotates by meshing with the chain. A pawl is fixed on the shaft of the sprocket, and the ratchet is fixed on the shaft of the conveying roller. The meshing end of the pawl engages with the ratchet through an elastic plate. The elastic plate provides a meshing preload. When the tire moves to the position on the conveying roller 303, the tire tread contacts the baffle, and the chain can drive the sprocket to rotate freely. Because the tire is blocked by the baffle, the friction between the tire and the conveying roller 303 is greater than the preload provided by the elastic plate, causing the pawl to slide on the ratchet, thereby stopping the conveying roller 303 with the tire on it from rotating.

[0064] In actual use, based on the above embodiments, when the diameter difference of the conveyed tires is too large, the support bladder 2023 located on the placement plate 202 cannot contact the tire rim. First, turn off the conveyor motor 103 and start the adjustment motor 104 at the same time, so that the sliding frame 105 drives the conveyor belt 201 on one side to slide on the conveyor frame 101, and adjust the distance between the conveyor belts 201. When the distance between the conveyor belts 201 is adjusted to a suitable distance, the adjustment motor 104 stops running. Then, after adjusting the fixing rod 212 to a suitable width, fix the fixing rod 212 to the fixing frame 106 and the sliding frame 105 with bolts. Then, start the conveyor motor 103 to make the conveyor belt 201 rotate. The placement plate 202 located on the conveyor belt 201 moves horizontally forward on the horizontal part of the conveyor belt 201. The rotating rod 214 on the fixing rod 212 rotates under the drive of the motor to a position that is perpendicular to the horizontal part of the conveyor belt 201 and close to the placement plate 202. During the movement of the placement plate 202, the connecting ring 2027 on the support bag 2023 gradually approaches the connector 213 on the rotating rod 214. When the connecting ring 2027 and the connector 213 are in contact... Upon contact, due to the pulling force generated by the continuous movement of the placement plate 202, the connector 213 smoothly extends into the connecting ring 2027. As the placement plate 202 moves further, the support bag 2023 detaches from the placement plate 202 under the action of the pulling force and hangs on the rotating rod 214. At this time, the motor judges that the support bag 2023 has been successfully hung on the rotating rod 214 according to the torque change, and drives the rotating rod 214 to rotate to the upper position, so that the staff can remove the support bag 2023. At the same time, the rotating rod 214 without the support bag 2023 hangs on it rotates to the position flush with the surface of the placement plate 202 under the drive of the motor, waiting for the next round of disassembly of the support bag 2023. Finally, after all the replacement support bladders 2023 have been removed, the workers install the support bladders 2023 that match the diameter of the new batch of tires onto the rotating rod 214 via the connecting ring 2027. The motor drives the rotating rod 214 to rotate, so that the rotating rod 214 with the support bladders 2023 installed is positioned above the placement plate 202. As the conveyor belt 201 continues to rotate, the new support bladders 2023 are accurately installed onto the placement plate 202, completing the rapid replacement of the support bladders 2023. This achieves adaptation to tires of different diameters and avoids the tedious process of manually disassembling and replacing each support bladder 2023, greatly shortening equipment downtime.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
