Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying device technology, specifically a tire inner wall spraying device. Background Technology
[0002] In the tire manufacturing and retreading industry, spraying the inner wall of a tire is a crucial process for improving tire performance. Whether it's the sealing coating applied to enhance air tightness during new tire production, the wear-resistant coating applied to repair inner wall damage during tire retreading, or the puncture-resistant protective layer applied to special vehicle tires (such as run-flat tires), precise and uniform spraying is essential to ensure a tight bond between the coating and the tire's inner wall, enabling it to perform its intended function.
[0003] Traditional manual spraying methods have significant drawbacks. In such operations, the tire must first be placed on an automatic rotating machine and started to rotate. Then, the worker holds a spray gun and sprays the inner wall of the tire. Since the tire is in a continuous rotating state, the worker must keep the relative position of the spray gun and the inner wall stable at all times. This is not only labor-intensive and cumbersome, but also prone to deviation of the spraying trajectory due to hand fatigue during long-term operation. This can result in uneven coating thickness or even missed spraying or overspraying.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing tire inner wall coating devices. Utility Model Content
[0005] To address the technical problem that existing workers need to maintain a stable relative position between the spray gun and the inner wall at all times, which is not only labor-intensive but also cumbersome to operate, this utility model provides a tire inner wall spraying device.
[0006] This utility model is achieved using the following technical solution: a tire inner wall spraying device, comprising an operating table and a turntable. The turntable is rotatably connected to the top of the operating table. One end of the operating table is fixedly connected to a side plate. One side of the side plate is fixedly connected to an I-beam. A first motor is mounted on the top of the I-beam. A threaded rod is fixedly connected to the bottom of the first motor. Both ends of the threaded rod are rotatably connected to the inside of the I-beam. One end of the threaded rod is threadedly connected to a threaded seat. A connecting block is fixedly connected to one side of the threaded seat. A lifting rod is fixedly connected to one end of the connecting block. A spray head is fixedly connected to the bottom of the lifting rod. A paint tube is fixedly connected to the top of the lifting rod. Two clamping plates are movably connected to the top of the turntable. A second motor is mounted on the bottom of the operating table. A rotating shaft is fixedly connected to the top of the second motor. A first gear is fixedly connected to the top of the rotating shaft. One end of the first gear is meshed with a second gear. The top of the second gear is fixedly connected to the bottom of the turntable.
[0007] Preferably, a handwheel is provided at one end of the turntable, and a bidirectional threaded rod is fixedly connected to the inner side of the handwheel, the bidirectional threaded rod being rotatably connected inside the turntable.
[0008] Preferably, the two ends of the bidirectional threaded rod are threadedly connected to two movable blocks, and the top of the movable blocks is fixedly connected to the bottom of the clamping plate.
[0009] Preferably, the top of the turntable is machined with two movable grooves, and the movable block is movably connected inside the movable grooves.
[0010] Preferably, the bottom of the second gear is fixedly connected to a limiting ring, which is rotatably connected inside the operating table.
[0011] Preferably, the threaded seat has two sliders fixedly connected to both ends, and the I-beam has two grooves fixedly connected to one side, with the sliders movably connected inside the grooves.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, the tire is first placed on top of the turntable and clamped in place. Then, the first motor is started, which drives the threaded rod to rotate. The threaded rod drives the threaded seat, connecting block, lifting rod, and spray head to move downward, so that the spray head is aligned with the inner wall of the tire. Then, the second motor is started, which drives the rotating shaft, the first gear, and the second gear to rotate. The second gear drives the turntable and the tire to rotate at a constant speed, which facilitates the spray head to spray evenly on the inner wall of the tire.
[0014] In use, this invention involves placing the tire on top of the turntable and then turning the handwheel. The handwheel will drive the bidirectional threaded rod to rotate, which in turn will drive the two movable blocks to move. The two movable blocks will then drive the two clamping plates to move closer together, thus facilitating the clamping and fixing of the tire. Attached Figure Description

[0021] Example 1: Please refer to Figure 1 - Figure 4 This embodiment of a tire inner wall spraying device includes an operating table 1 and a turntable 2. The turntable 2 is rotatably connected to the top of the operating table 1. One end of the operating table 1 is fixedly connected to a side plate 3. One side of the side plate 3 is fixedly connected to an I-beam 5. A first motor 6 is mounted on the top of the I-beam 5. A threaded rod 7 is fixedly connected to the bottom of the first motor 6. Both ends of the threaded rod 7 are rotatably connected to the inside of the I-beam 5. One end of the threaded rod 7 is threadedly connected to a threaded seat 8. One side of the threaded seat 8 is fixedly connected to a connecting block 9. One end of block 9 is fixedly connected to a lifting rod 10, the bottom of the lifting rod 10 is fixedly connected to a nozzle 4, the top of the lifting rod 10 is fixedly connected to a paint pipe 11, the top of turntable 2 is movably connected to two clamping plates 15, the bottom of the operating table 1 is equipped with a second motor 17, the top of the second motor 17 is fixedly connected to a rotating shaft 18, the top of the rotating shaft 18 is fixedly connected to a first gear 19, one end of the first gear 19 is meshed with a second gear 20, and the top of the second gear 20 is fixedly connected to the bottom of turntable 2;
[0022] When it is necessary to spray the inner wall of the tire, the tire is first placed on the top of the turntable 2 and clamped and fixed by the two clamps 15. Then the first motor 6 is started. The first motor 6 will drive the threaded rod 7 to rotate. The threaded rod 7 will drive the threaded seat 8 to move downward. The threaded seat 8 will drive the connecting block 9 to move. The connecting block 9 will drive the lifting rod 10 to move. The lifting rod 10 will drive the spray head 4 to move downward, so that the spray head 4 is aligned with the inner wall of the tire in preparation for spraying.
[0023] Secondly, by starting the second motor 17, the second motor 17 will drive the rotating shaft 18 to rotate, the rotating shaft 18 will drive the first gear 19 to rotate, the first gear 19 will drive the second gear 20 to rotate, the second gear 20 will drive the turntable 2 to rotate, and the turntable 2 will rotate the tire at a constant speed. During this process, the spray nozzle 4 can spray the inner wall of the rotating tire evenly.
[0024] Furthermore, a handwheel 12 is provided at one end of the turntable 2, and a two-way threaded rod 13 is fixedly connected to the inner side of the handwheel 12. The two-way threaded rod 13 is rotatably connected to the inside of the turntable 2, and two movable blocks 14 are threadedly connected to both ends of the two-way threaded rod 13. The top of the movable blocks 14 is fixedly connected to the bottom of the clamping plate 15.
[0025] When it is necessary to clamp and fix the tire, first place the tire on the top of the turntable 2, then turn the handwheel 12.

The threaded rod 7 drives the threaded seat 8 to move downward. The threaded seat 8 drives the connecting block 9 and the lifting rod 10 to move. The lifting rod 10 drives the spray head 4 to move downward, so that the spray head 4 is aligned with the inner wall of the tire.
