Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically a large tire rear inflation and centering device. Background Technology

[0002] Currently, the rear inflation devices used in bias-ply tires and agricultural radial tires on the market are basically vertical rear inflation devices. During operation, the tire loading mechanism unloads the freshly vulcanized tires onto the front of the rear inflation device. The rear inflation device then transports the tires to the rear inflation center via a flipping or translating mechanism for inflation and shaping. During the process of transporting the tires to the rear inflation center, the tires may shift left or right, causing misalignment between the tire center and the center of the rear inflation device. This results in air leakage during inflation, and in severe cases, inflation may fail altogether. This requires manual adjustment, and since engineering tires are heavy, at least two workers are needed for adjustment, severely impacting production efficiency and posing certain safety risks. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a large-scale tire rear inflation and centering device, which realizes automatic tire centering during transportation and is applicable to tires of different diameters. It has a simple structure, high efficiency, and saves costs.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A large tire rear inflation and centering device includes an inclined main support frame, inside which several long rollers are evenly arranged. A left and right centering frame are mounted on the main support frame at a certain angle. Two guide rods are located below the long rollers inside the main support frame. A left and right connecting plate of equal length are slidably connected between the two guide rods. The left and right centering frames are fixed to the left and right connecting plates respectively. A left and right connecting rod of equal length is hinged to the center of the left and right connecting plates respectively. The inner ends of the left and right connecting rods are hinged to the two ends of a rotating plate. The center of the rotating plate is hinged to a shaft seat at the bottom center of the main support frame. A geared motor is mounted on the side of the main support frame, and the geared motor drives the left and right connecting plates to move in opposite directions or towards each other via a threaded pair.

[0006] Furthermore, several longitudinal rollers are evenly arranged inside the left and right centering frames.

[0007] Furthermore, the output end of the geared motor is connected to the screw, and the screw is threadedly engaged with the right connecting plate.

[0008] Furthermore, the guide rod is provided with a sliding guide sleeve, and the left and right centering frames are fixedly connected to the left and right connecting plates through the sliding guide sleeve.

[0009] Compared with the prior art, the advantages and effects of this utility model are:

[0010] 1. By tilting the support frame, the tires can slide down under gravity, saving the need for a transportation power system and effectively reducing production costs;

[0011] 2. The left and right centering frames adopt a double-row vertical roller, flared arrangement. The entire centering process does not require external force to push. The tire slides in from the flared opening and slides out to complete the automatic centering. This not only improves the efficiency of use, but also avoids damage to the tires caused by external force pushing.

[0012] 3. The distance between the left and right centering frames is adjusted by using a motor to drive a multi-link control. It can be adjusted at any time according to different tire diameters, and only needs to be adjusted once for each batch of tires. The structure is simple and easy to operate.

[0017] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0018] The large tire rear inflation and centering device described in this embodiment, such as Figure 1 and 2 As shown, it includes a main support 1 that is set at an inclination. Several transverse long rollers 2 are evenly arranged inside the main support 1. A left centering frame 3 and a right centering frame 4 are arranged at a certain angle on the main support 1. Several longitudinal rollers are evenly arranged inside the left and right centering frames 3 and 4.

[0019] like Figure 1 , 2As shown in Figure 3, two guide rods 5 are installed below the long roller 2 inside the main support 1. Sliding guide sleeves 6 are fitted on the guide rods 5. The two ends of the left connecting plate 7 and the right connecting plate 12 are respectively fixed to the sliding guide sleeves 6 of the two guide rods 5. The two support legs of the left centering frame 3 pass through the gap of the long roller 2 and are respectively fixed to the sliding guide sleeves 6 fixed to the left connecting plate 7. The two support legs of the right centering frame 4 pass through the gap of the long roller 2 and are respectively fixed to the sliding guide sleeves 6 fixed to the right connecting plate 12. Both the left and right centering frames 3 and 4 can slide along the guide rods 5. The center of the left and right connecting plates 7 and 12 are respectively hinged to the left connecting rod 8 and the right connecting rod 11. The inner ends of the left and right connecting rods 8 and 11 are respectively hinged to the two ends of the rotating plate 9. A bearing seat 10 is set at the center of the bottom of the main support 1. The center of the rotating plate 9 is hinged to the rotating shaft of the bearing seat 10. The left connecting plate 7 and the right connecting plate 12 are set to the same length. The left connecting rod 8 and the right connecting rod 11 are set to the same length.

[0020] like Figure 1 , 2 As shown in Figure 3, a geared motor 13 is installed on the side of the main support 1. The output end of the geared motor is connected to the screw 14. The screw 14 passes through the screw plate 15 and engages with the nut seat on the right connecting plate 12. The rotation of the geared motor 13 drives the screw 14 to rotate, which in turn drives the right connecting plate 12 to move. This causes the right centering frame 4 to move along the guide rod 5. At the same time, the movement of the right connecting plate 12 will drive the right connecting rod 11 to move, causing the rotating plate 9 to rotate around the shaft seat 10. This will drive the left connecting rod 8 to move, which in turn drives the left connecting plate 7 to move. Finally, the left centering frame 3 will also move along the guide rod 5. Since the connecting plate and the connecting rod are designed to be symmetrical, the left centering frame 3 and the right centering frame 4 will move the same distance in opposite directions, ensuring that the distances of the left centering frame 3 and the right centering frame 4 from the rear inflation center are consistent.

[0021] The working principle of this embodiment is as follows:

[0022] 1. When using, first adjust the distance between the last roller of the left and right centering frames 3 and 4 according to the requirements of different tire diameters through the reduction motor 13;

[0023] 2. After setting the distance between the left and right centering frames 3 and 4, the tire can be placed on the main support 1. Since the main support 1 is set at an angle, the tire will slide down by itself under the action of gravity.

[0024] 3. The tire slides into the flared openings of the left and right centering frames 3 and 4, and automatically completes the centering when it slides out.
