Technical Field

[0001] This utility model relates to the technical field of tire spraying equipment, specifically a tire spraying equipment for rubber tire production. Background Technology

[0002] In the rubber tire manufacturing industry, after tires complete vulcanization molding, a layer of water-based release agent must be sprayed onto their surface. This serves three purposes: first, to prevent tires from sticking together due to surface adhesion during subsequent stacking, storage, and transportation, thus avoiding surface damage caused by tearing; second, to give the tire sidewalls a uniform, glossy, and deep black appearance, enhancing the product's commercial value; and third, to form a protective film on the tire surface, effectively resisting the erosion of ultraviolet rays and ozone in the short term, preventing premature aging and cracking.

[0003] Currently, most existing tire spraying equipment uses a simple mechanical positioning and clamping method, which requires operators to manually fix and clamp the tires. For example, there is a tire spraying device for rubber tire production with announcement number CN222587047U and a tire spraying mechanism for tire production with announcement number CN222587047U. This results in low efficiency and inconvenience in fixing and clamping the tires. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1

[0020] like Figure 1-3 As shown, a tire spraying device for rubber tire production includes a C-shaped base 1, which consists of a top plate, a bottom plate, and a rear vertical plate. A control panel 2 is mounted on the side wall of the C-shaped base 1, a rotating clamping structure is mounted on the top plate of the C-shaped base 1, and a spraying structure is mounted on the inner bottom surface of the C-shaped base 1, located on one side of the rotating clamping structure. It should be noted that the device is placed at the target position via the C-shaped base 1 and connected to a power source. The control panel 2 has a built-in microcontroller, which can be programmed to control the device by writing a control program. Since this is existing technology, it will not be described in detail here. Tire placement markings can be set on the C-shaped base 1, corresponding to the rotating clamping structure, to facilitate the operator in placing the tire in the target area.

[0021] The rotating clamping structure includes a height-adjustable rotator, which is mounted on the top plate of the C-shaped base 1. An electric slip ring 3 is fitted on the height-adjustable rotator, and a disc 4 is mounted on one end of the electric slip ring 3. Multiple first electric push rods 5 are mounted in a circular array on the disc 4 with the height-adjustable rotator as the center. Each first electric push rod 5 is mounted on the disc 4 via a bracket. The telescopic end of the first electric push rod 5 can be raised outside the disc 4. An arc-shaped support 6 is mounted on the telescopic end of the first electric push rod 5. A sleeve 7 is mounted on the upper wall of the disc 4. The sleeve 7 has multiple first clearance openings 8 corresponding to the first electric push rods 5 for the telescopic ends of the first electric push rods 5 to extend out. The arc-shaped support 6 is located outside the sleeve 7.

[0022] Specifically, the height-adjustable rotator includes a second electric push rod 12, which is fixedly inserted into the top plate of the C-shaped base 1. A crossbeam 13 is mounted on the telescopic end of the push rod 12, and a motor 14 is mounted on the lower wall of the crossbeam 13. An electric slip ring 3 is fitted onto the drive end of the motor 14. A first guide rod 19 is mounted on the upper wall of the crossbeam 13, and the first guide rod 19 is movably inserted into the top plate of the C-shaped base 1. The length of the first guide rod 19 is sufficient to prevent it from falling off the top plate. It can move up and down along the holes in the top plate to protect the telescopic end of the second electric push rod 12.

[0023] The tire is raised and lowered by the operation of the second electric push rod 12, and the tire is rotated by the operation of the motor 14, so that the outer surface of the tire is in contact with the water-based release agent. The electric slip ring 3 is used to prevent the wires from getting tangled.

[0024] A second guide rod 20 is installed on the arc-shaped support 6, and a support plate 21 is installed on the bracket. The second guide rod 20 is movably inserted into the support plate 21, ensuring that it will not fall off the support plate 21. The sleeve 7 is also provided with multiple second clearance slots 22 corresponding to the second guide rod 20, which are used to protect the telescopic end of the first electric push rod 5. Preferably, a U-shaped frame 23 is installed on the lower wall of the cross frame 13, and the drive end of the motor 14 moves through the U-shaped frame 23 to protect the drive end of the motor 14.

[0025] After vulcanization, the tire is removed from the mold, cooled to a certain temperature, and shaped. It is then placed on the C-shaped seat 1. At this time, multiple first electric push rods 5 are in a retracted state. The height adjustment rotator is controlled via the control panel 2, causing the disc 4, first electric push rods 5, and arc-shaped support 6 to descend to their extreme positions. The arc-shaped support 6 is then aligned with the inner ring of the tire. The control panel 2 controls all first electric push rods 5 to extend outwards synchronously, pushing the arc-shaped support 6 at their tops to expand towards the inner ring of the tire until the inner arc surfaces of all the arc-shaped support 6 are tightly pressed against and support the inner ring of the tire. When multiple first electric push rods 5 extend outwards synchronously, even if the initial tire placement axis is aligned with the height adjustment rotator axis... With slight deviations in the line, the tire will passively undergo a small displacement under the uniform radial thrust of multiple arc-shaped supports 6, eventually aligning its central axis with the rotation axis of the height adjustment rotator, achieving adaptive coaxial alignment. A pressure sensor can be installed at the telescopic end of the first electric push rod 5 to monitor the tension force on the inner ring of the tire in real time. When the pressure value reaches the preset safety threshold that ensures reliable clamping without damaging the tire body, the control panel 2 issues a command, and the first electric push rod 5 stops extending. This is suitable for fixing tires of different specifications. Subsequently, the height adjustment rotator drives the tire to the limit position, eliminating the need for operators to manually fix the tire to the rotating clamping structure, making operation simple and convenient.

[0026] The spraying structure includes a movable support, which is installed on the inner bottom surface (base plate) of the C-shaped base 1. A C-shaped frame 9 is installed on the movable support. Conveyor pipes 10 are inserted into one side wall and the upper and lower walls of the C-shaped frame 9. A nozzle 11 is installed at one end of the conveyor pipe 10. The movable support includes a lead screw module 15, which is installed on the inner bottom surface of the C-shaped base 1. A third electric push rod 16 is installed on the movable end of the lead screw module 15. The C-shaped frame 9 is installed at one end of the third electric push rod 16. A connecting pipe 17 is installed at one end of all conveyor pipes 10. A feed pipe 18 is inserted into the connecting pipe 17.

[0027] It should be noted that the tire is raised to the preset spraying height by the height adjustment rotator. The height of the C-frame 9 is adjusted by the third electric push rod 16 so that the space enclosed by the C-frame 9 is aligned with the tire. The screw module 15 works, and the C-frame 9 drives the conveying pipe 10 and the spray nozzle 11 on it to approach the tire. The outer surface of the tire is opposite to the multiple spray nozzles 11 installed on the C-frame 9. The feed pipe 18 is connected to the water-based release agent conveying system. The water-based release agent is sprayed onto the outer surface of the tire through the spray nozzles 11 by the height adjustment rotator. Only one operation is needed to spray the outer sidewall of the tire, which improves work efficiency. The sprayed release agent can form a thin film to prevent the tires from sticking together during stacking, storage and transportation, and make the tire surface present a uniform, bright and deep black color, improving the appearance quality of the product. During the short-term storage and transportation of the tire after leaving the factory, it can protect the tire sidewall from the slight corrosion of ultraviolet radiation and ozone, and prevent the surface from showing signs of aging and cracking. The sleeve 7 is used to block some of the water-based release agent that is dispersed in the environment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
