Description

Technical Field

[0001] This utility model relates to the field of tire spraying technology, specifically a self-sealing tire uniform spraying machine. Background Technology

[0002] Tires are frequently punctured or blowouted during driving, causing unnecessary losses and even accidents. Tire puncture and blowout prevention technology has emerged to address this issue. This technology improves tire strength by spraying a polymer material onto the inner wall of the tire. However, due to the U-shaped shape of the tire's inner wall, the radius (R-angle) is high at the edges and low in the middle. Since liquids flow downhill (the polymer material is liquid before curing and becomes a non-flowing semi-solid after curing), during the spraying process, the polymer material on the edges flows downhill. This results in the polymer material being thicker in the middle and thinner at the edges after spraying, leading to poor puncture resistance on the sides and waste of polymer material.

[0003] To address the aforementioned issues, we propose a self-sealing tire uniform spraying machine. Utility Model Content

[0004] To address the problems in the background art, this utility model provides a self-sealing tire uniform spraying machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A self-sealing tire uniform spraying machine includes a spraying box. The inner cavity of the spraying box contains a material storage module, a heating module, a feeding module, and a spray gun, as well as a spray gun moving module for moving the spray gun. A spraying groove is located at the center of the right end of the spraying box. A support plate is located at the center of the inner side of the spraying groove. A tire rotating assembly is located at the center of the upper end of the support plate, and a tilt adjustment assembly is located at the bottom of the support plate. The tire rotating assembly includes a right roller and a left roller. The right roller is movably mounted on the right side of the upper end of the support plate and rotates by a drive motor. The left roller is parallel to the center of the left end of the right roller and movably mounted on the left side of the upper end of the support plate. The tilt adjustment assembly includes a servo motor located at the center of the left end of the support plate and fixedly mounted on the upper surface of the spraying groove. A rotating shaft is mounted on the output end of the servo motor and movably mounted at the center of the upper end of the spraying groove. The rotating shaft is located at the center of the bottom end of the support plate and is fixedly connected to the bottom of the support plate by two sets of fixing parts.

[0007] Preferably, right limiting rollers are provided at both ends of the right roller, and left limiting rollers are provided at both ends of the left roller.

[0008] Preferably, a central limiting roller is provided on both sides of the upper end of the support plate, and the central limiting roller is located between the right limiting roller and the left limiting roller.

[0009] Preferably, the two sets of fasteners are located on both sides of the bottom end of the support plate, and are both fixedly connected to the bottom of the support plate.

[0010] Preferably, the drive motor is located on the right end of the right roller, the drive motor is fixedly mounted on the upper surface of the support plate, and both the drive motor and the head end of the right roller are equipped with synchronous pulleys, and the two sets of synchronous pulleys are connected by a synchronous belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This solution incorporates a tire rotation component that rotates the tire, allowing the spray gun to evenly coat the tire's inner wall. Simultaneously, a tilt adjustment component allows for tire tilting, ensuring the tire's inner radius (R-angle) is at its lowest point. This effectively prevents polymer material from flowing to the center of the tire's bottom. The tilt adjustment component ensures that spraying initially focuses on one side, where the material's reaction begins, reducing flow. Then, spraying shifts to the other side, finally finishing the center. This results in a uniform thickness on the tire's inner wall, from the edge R-angle to the center, solving the problem of thinner coatings at the edges, enhancing puncture resistance, and preventing polymer material waste.

[0019] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0020] Example: Refer to Figure 1 - Figure 5 As shown, this embodiment of a self-sealing tire uniform spraying machine includes a spraying box 1. The inner cavity of the spraying box 1 is provided with a material storage module, a heating module, a feeding module, and a spray gun 2, as well as a spray gun moving module for moving the spray gun 2. Each module in the inner cavity of the spraying box 1 adopts existing mature technology and will not be described in detail. During use, the paint needs to be added into the material cylinder in the corresponding material storage module and the heating module needs to be turned on for heating.

[0021] A spraying tank 3 is provided at the middle of the right end of the spraying box 1. A support plate 4 is provided at the middle of the inner side of the spraying tank 3. A tire rotation component is provided at the middle of the upper end of the support plate 4. A tilt adjustment component is provided at the bottom of the support plate 4.

[0022] The tire rotation assembly includes a right roller 5 and a left roller 6. The right roller 5 is movably mounted on the upper right side of the support plate 4 and is driven to rotate by the drive motor 10. The left roller 6 is mounted parallel to the middle of the left end of the right roller 5 and is movably mounted on the upper left side of the support plate 4. It is driven by the drive motor 10 to rotate the right roller 5, thereby rotating the tire placed on the right roller 5, and then rotating the left roller 6.

[0023] The tilt adjustment assembly includes a servo motor 11, which is located at the middle of the left end of the support plate 4 and is fixedly installed on the upper surface of the spray tank 3. A rotating shaft 12 is installed at the output end of the servo motor 11. The rotating shaft 12 is movably installed at the middle of the upper end of the spray tank 3 and is located at the middle of the bottom end of the support plate 4. It is fixedly connected to the bottom of the support plate 4 by two sets of fixing parts 13. The servo motor 11 drives the rotating shaft 12 to rotate, thereby driving the support plate 4 to rotate, so that the support plate 4 drives the tire rotation assembly to tilt, thereby achieving the tilt adjustment of the tire and preventing the paint from flowing to the middle of the bottom of the tire.

[0024] In some examples, right limit rollers 7 are provided at both ends of the right roller 5, left limit rollers 8 are provided at both ends of the left roller 6, and middle limit rollers 9 are provided on both sides of the upper end of the support plate 4. The middle limit rollers 9 are located between the right limit rollers 7 and the left limit rollers 8.

[0025] Among them, the right limiting roller 7, the left limiting roller 8 and the middle limiting roller 9 all play a role in limiting the rotation of the tire, preventing the tire from falling off during rotation and enhancing the stability of the tire when rotating.

[0026] In some examples, two sets of fasteners 13 are located on both sides of the bottom end of the support plate 4, and are fixedly connected to the bottom of the support plate 4 to enhance the stability of the connection between the support plate 4 and the rotating shaft 12.

[0027] In some examples, the drive motor 10 is located on the right side of the right roller 5. The drive motor 10 is fixedly installed on the upper surface of the support plate 4. Both the drive motor 10 and the head end of the right roller 5 are equipped with synchronous pulleys, and the two sets of synchronous pulleys are connected by a synchronous belt 14. Under the transmission action of the synchronous belt 14 and the synchronous pulleys, the drive motor 10 can drive the right roller 5 to rotate.

[0028] The working principle of this utility model is as follows:

[0029] In use, the tire to be sprayed is placed between the right roller 5 and the left roller 6. Then, the tire model is input through the control module to start the spraying work. First, the spray gun 2 is transported into the inner cavity of the tire for spraying under the action of the spray gun moving module. At the same time, during the spraying process, the drive motor 10 drives the right roller 5 to rotate, thereby causing the tire and the left roller 6 to rotate, so that the spray gun 2 can spray the inner wall of the tire evenly.

[0030] In addition, during the spraying process, the tilt adjustment component is activated, and the servo motor 11 drives the rotating shaft 12 to rotate, thereby driving the support plate 4 to rotate, so that the support plate 4 is in a tilted state, thereby causing the tire to be in a tilted state, so that the R angle of the tire cavity is at the lowest position, thus effectively preventing the polymer material from flowing to the bottom middle position of the tire.

[0031] Throughout the spraying process, the tire rotation assembly first rotates the tire at a low speed, then tilts the tire to one side to begin spraying. After 10 seconds of spraying, it tilts to the other side for another 10 seconds. Then, the tire is returned to center and the rotation speed is increased to continue spraying. When there are 20 seconds left in the spraying time, the rotation speed is reduced until the spraying is complete. After the spraying is finished, the spray gun 2 returns to its original position. Spraying is complete.

[0032] This invention, through the aforementioned structure, allows for initial spraying to one side, where the material begins to react and becomes less prone to flow. Then, the spraying is directed to the other side, with the middle being sprayed last. After spraying, the thickness at the inner wall of the tire, including the edge and the center, is the same, thus solving the problem of thin edges, enhancing the puncture resistance on both sides, and avoiding waste of polymer materials.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
