[0027] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.
[0028] Example 1:
[0029] like Figures 1-2 As shown, a tire coating spraying device includes a conveying mechanism 1 for transporting tires, a spraying mechanism 2 for spraying coating on the inner wall of the tire, a clamping mechanism 4 for holding the tire, and an adjusting mechanism 3 for adjusting the tire position. The clamping mechanism 4 includes an outer wall 41 and an inner wall 43 of an airbag, forming an inner cavity 42 for inflation between the outer wall 41 and the inner wall 43. A tire clamping area 44 for holding the tire is formed inside the inner wall 43. The inner cavity 42 is connected to an air compressor 46 via a pipe 45. A switching valve 47 is installed on the pipe 45, which effectively controls the gas flow, ensuring the accuracy and safety of the airbag clamping. The conveying mechanism 1 utilizes existing technology, employing a conveyor belt, chain, and motor.
[0030] This invention not only enables efficient spraying of the inner wall of tires, but also adapts to tires of different specifications through a precise position adjustment mechanism, ensuring stability during the spraying process. It integrates a conveying mechanism 1, a spraying mechanism 2, a clamping mechanism 4, and a position adjustment mechanism 3. The clamping mechanism 4 adopts an airbag structure, which can be inflated to firmly clamp the tire.
[0031] Example 2:
[0032] like Figure 3As shown, a tire coating spraying device differs from Embodiment 1 in that the spraying mechanism 2 includes a lateral adjustment mechanism mounted on the side wall of the conveying mechanism 1, a second longitudinal adjustment mechanism slidably connected to the lateral adjustment mechanism, and a bracket 29 slidably connected to the second longitudinal adjustment mechanism. A nozzle 210 is mounted on the top of the bracket 29. The spraying mechanism 2 is equipped with adjustable lateral and longitudinal adjustment mechanisms to ensure that the nozzle 210 can accurately reach various parts of the tire's inner wall, achieving high-quality coating spraying. Furthermore, the height adjustment mechanism allows the spraying device to adapt to tires of different diameters, further enhancing the flexibility and applicability of the equipment.
[0033] Further, the lateral adjustment mechanism includes a first mounting bracket 23 mounted on the side wall of the conveying mechanism 1, a first lead screw 21 mounted on the first mounting bracket 23, a first motor 22 drivenly connected to the first lead screw 21, and a first slider 24 mounted on the first lead screw 21. The first motor 22 is mounted on the first mounting bracket 23. The second longitudinal adjustment mechanism includes a second mounting bracket 28 connected to the first slider 24, a second lead screw 25 mounted on the second mounting bracket 28, a second motor 26 drivenly connected to the second lead screw 25, and a second slider 27 mounted on the second lead screw 25. The second motor 26 is mounted on the second mounting bracket 28, and a bracket 29 is fixedly connected to the second slider 27.
[0034] For example Figure 1 As shown, the adjustment mechanism 3 includes a third longitudinal adjustment mechanism installed on the side wall of the conveying mechanism 1 and a height adjustment mechanism slidably connected to the third longitudinal adjustment mechanism.
[0035] Furthermore, the third longitudinal adjustment mechanism includes a third mounting bracket 37 mounted on the side wall of the conveying mechanism 1, a third lead screw 35 mounted on the third mounting bracket 37, a third motor 34 drivenly connected to the third lead screw 35, and a third slider 36 mounted on the third lead screw 35. The third motor 34 is mounted on the third mounting bracket 37. The position of the tire can be adjusted through the third longitudinal adjustment mechanism so that the spraying mechanism 2 can adapt to tires of different sizes. The height adjustment mechanism includes a fourth mounting bracket 31 connected to the third slider 36, a fourth lead screw 32 mounted on the fourth mounting bracket 31, a fourth motor 38 drivenly connected to the fourth lead screw 32, and a fourth slider 33 mounted on the fourth lead screw 32. The fourth motor 38 is mounted on the fourth mounting bracket 31, and the fourth slider 33 is connected to the outer wall 41 of the airbag of the clamping mechanism 4 through a connecting rod 39.
[0036] The working principle of this utility model is as follows:
[0037] 1) Tire transfer: The conveyor mechanism 1 is responsible for transferring the tires to be painted from one station to another, ensuring that each tire can accurately reach the painting position.
[0038] 2) Tire clamping and positioning: When the tire reaches the designated position, the adjustment mechanism 3 adjusts the height of the tire through the third longitudinal adjustment mechanism and the height adjustment mechanism to make it in the most suitable position for spraying.
[0039] The inner cavity 42 between the outer wall 41 and the inner wall 43 of the airbag in the clamping mechanism 4 is connected to the air compressor 46 through the pipe 45. When it is necessary to fix the tire, the clamping mechanism 4 is lowered to directly above the tire through the height adjustment mechanism. When it continues to lower, the tire enters the tire clamping area 44. The air compressor 46 inflates the inner cavity 42, causing the airbag to expand and tightly adhere to the outer wall of the tire, forming a stable tire clamping area 44, thereby firmly clamping the tire and preventing it from moving during the spraying process.
[0040] 3) Spraying process: The spraying mechanism 2 is installed on the side wall of the conveying mechanism 1 and includes a horizontal adjustment mechanism and a second vertical adjustment mechanism. These two mechanisms are controlled by the first lead screw 21 and the second lead screw 25 driven by the first motor 22 and the second motor 26, respectively, and are used to precisely adjust the position of the nozzle 210.
[0041] Before spraying begins, the position of nozzle 210 is adjusted by the lateral adjustment mechanism and the second longitudinal adjustment mechanism so that it can be accurately aligned with the target area on the inner wall of the tire.
[0042] Once the position is determined, the nozzle 210 begins to spray the coating material. Since the position of the nozzle 210 can be flexibly adjusted and the nozzle 210 is an automatically rotating nozzle, it can ensure that the coating material evenly covers the entire inner surface of the tire.
[0043] To ensure coating quality and efficiency, the device is equipped with an automatic control system to coordinate the actions of various mechanisms, such as controlling the start and stop of the motor and monitoring air pressure.
[0044] 4) After the spraying is completed, the clamping mechanism 4 descends through the height adjustment mechanism, the air compressor 46 releases the gas in the inner cavity 42, the airbag contracts, and the tire is released. At this time, the conveying mechanism 1 starts again, and the tire that has been sprayed is transferred to the next process or collection area, and the next tire is clamped and sprayed automatically.
[0045] Through the synergistic effect of the above components, this invention achieves automated, efficient and high-quality tire inner wall coating spraying, while also possessing good adaptability and operational flexibility.
