[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a flexible tire feeding mechanism. (Refer to...) Figure 1 and Figure 2 A flexible tire feeding mechanism includes an inner support device 1, a gripper device 2 on the top of the inner support device 1, a roller conveyor device 5 on one side of the inner support device 1, an intermittent feeding mechanism 3 on the surface of the roller conveyor device 5, and a lifting mechanism 4 on the bottom of the roller conveyor device 5.

[0026] The intermittent feeding mechanism 3 includes a U-shaped frame 301, which is disposed on the surface of the roller conveyor device 5. The U-shaped frame 301 is rotatably connected to the surface of the roller conveyor device 5 via a rotating shaft. A connecting plate 302 is fixedly connected to one end of the U-shaped frame 301, and a connecting block 303 is disposed at the other end of the U-shaped frame 301. Limiting rods 304 are fixedly connected to the surfaces of both the connecting plate 302 and the connecting block 303. The limiting rods 304, the connecting plate 302, and the connecting block 303 are used in conjunction with the roller conveyor device 5. By setting up the intermittent feeding mechanism 3, The swing of the U-shaped frame 301 drives the connecting plate 302 and the connecting block 303 to move alternately. During the conveying process, the limiting rod 304 moves synchronously with the movement of the U-shaped frame 301 and can pass through the space between adjacent rollers in the roller conveyor device 5, thereby intercepting and releasing the tires in the conveying process. The distance between the connecting plate 302 and the connecting block 303 allows one tire to pass through, thereby realizing the individual separation and intermittent conveying of tires, improving the stability of the conveying process, increasing production efficiency, and reducing labor intensity and operational risks.

[0027] The lifting mechanism 4 includes a base 402, which is fixedly connected to the bottom of the roller conveyor 5. A first motor 401 is fixedly connected to the top of the base 402. The output end of the first motor 401 extends through the inner wall of the base 402. A transmission rod 403 is fixedly connected to the output end of the first motor 401. The transmission rod 403 is rotatably connected to the inner wall of the base 402. An eccentric block 404 is fixedly connected to the surface of the transmission rod 403. The surface of the eccentric block 404 contacts the bottom of the connecting plate 302, and the bottom of the connecting plate 302 contacts the top of the base 402. By setting up the lifting mechanism 4, the first motor 401 drives the eccentric block 404 to rotate, pushing the connecting plate 302 to move upward, causing the U-shaped frame 301 to swing back and forth, thereby producing alternating movements. This can transform the rotational motion into regular intermittent motion, ensuring that the tires are separated in an orderly manner during the conveying process and improving the stability of production.

[0028] Reference Figure 2 A tension spring 8 is provided on the side of the base 402 opposite to the connecting plate 302. One end of the tension spring 8 is fixedly connected to the top of the base 402, and the other end of the tension spring 8 is fixedly connected to the bottom of the connecting plate 302. The tension spring 8 can store elastic potential energy and automatically release energy after the external force is removed, so that the U-shaped frame 301 returns to its original position and ensures the stability of the swing of the U-shaped frame 301.

[0029] Reference Figure 3 A positioning rod 9 is fixedly connected to one side of the connecting block 303. There are two positioning rods 9. The surface of the positioning rod 9 contacts the inner wall of the U-shaped frame 301. The positioning rod 9 can extend the connecting block 303. By adjusting the position of the positioning rod 9 in the U-shaped frame 301, it can adapt to tires of different sizes and ensure the stability of intermittent conveying.

[0030] Reference Figure 3 The positioning rod 9 and the inner wall of the U-shaped frame 301 are both provided with positioning grooves 10. There are several positioning grooves 10. The inner wall of the positioning groove 10 is threaded with a positioning pin 11. The positioning rod 9 is fixedly connected to the inner wall of the U-shaped frame 301 through the positioning grooves 10 and the positioning pins 11. By setting the positioning grooves 10 and the positioning pins 11, when the positioning rod 9 is adjusted according to the tire size, the positioning pins 11 are inserted into the corresponding positioning grooves 10, which can quickly fix the positioning rod 9 and prevent the positioning rod 9 from shifting or shaking during the operation.

[0031] Reference Figure 4A mounting frame 7 is fixedly connected to one side of the roller conveyor device 5. A slide rod 13 is fixedly connected to the inner wall of the mounting frame 7. A rack 12 is fixedly connected to the inner wall of the mounting frame 7. A sliding block 14 is provided on the surface of the mounting frame 7. The slide rod 13 passes through the inner wall of the sliding block 14. A second motor 15 is fixedly connected to one side of the sliding block 14. The output end of the second motor 15 passes through the inner wall of the sliding block 14. A gear 16 is fixedly connected to the surface of the output end of the second motor 15. The surface of the gear 16 meshes with the surface of the rack 12. Through the sliding block 14, the second motor 15 drives the gear 16 to move along the path of the rack 12, which can drive the sliding block 14 to reciprocate, thereby synchronously driving the gripper device 2 to move. The gripper device 2 clamps the tire on the roller conveyor device 5, which facilitates the smooth progress of subsequent assembly operations.

[0032] Reference Figure 4 A bracket 6 is fixedly connected to the top of the sliding block 14, and a third motor 19 is fixedly connected to the top of the bracket 6. The output end of the third motor 19 extends through the inner wall of the bracket 6, and a threaded rod 18 is fixedly connected to the output end of the third motor 19. The threaded rod 18 is rotatably connected to the inner wall of the bracket 6, and an installation rod 17 is fixedly connected to the inner wall of the bracket 6. The threaded rod 18 is set and the third motor 19 drives the threaded rod 18 to rotate, thereby realizing the lifting and lowering movement of the gripper device 2, improving the gripping flexibility and adapting to the operation needs of different height positions.

[0033] Reference Figure 4 The surfaces of the threaded rod 18 and the mounting rod 17 are provided with a movable plate 20. The movable plate 20 is slidably connected to the inner wall of the bracket 6 through the threaded rod 18. The bottom of the movable plate 20 is fixedly connected to the top of the gripper device 2. The movable plate 20 can connect the gripper device 2 to the threaded rod 18, ensuring the stability of the gripper device 2 moving up and down.

[0034] Working principle: The inner support device 1 mainly consists of a lead screw, adjustable pull rod, handle, and base 402. By rotating the handle, the double-ended lead screw drives the pull rod to retract, and the inner support petals can be adjusted to different sizes, thus opening up tires of different sizes. The gripper device 2 mainly consists of a three-axis pneumatic gripper, a fixed plate, a spring piston, and an adapter joint. The spring piston can be adjusted on the fixed seat to accommodate tires of different outer diameters. Utilizing vacuum adsorption, the size can be adjusted arbitrarily, and multi-angle adsorption of different curved surfaces can be achieved, ensuring gripping stability. The roller conveyor device 5 uses two rollers as a group, with a sprocket installed at the end of each roller. The sprockets mesh with the sprockets on adjacent rollers via chains. When the drive device is started, the power... The power is transmitted to one of the driving rollers, which, through the cooperation of a sprocket and chain, sequentially transmits power to the driven rollers in the same group, thereby achieving synchronous rotation of the entire group of rollers and enabling tire transport. The inner support device 1, gripper device 2, and roller conveyor device 5 are existing technologies and will not be elaborated upon further. The worker uses external tools to place the tires sequentially on the rollers of the roller conveyor device 5, and starts the roller conveyor device 5 via an external control switch. The roller conveyor device 5 is powered by an external power source, driving the tires to move. At this time, the user starts the first motor 401 via an external control switch. The first motor 401 is powered by an external power source, and its output drives the transmission rod 403 to rotate. The rotation of the transmission rod 403... The eccentric block 404 rotates, and its asymmetrical surface remains in contact with the bottom of the connecting plate 302. During rotation, it periodically pushes the connecting plate 302 upward. When the eccentric block 404 rotates and lifts one end of the connecting plate 302, the tension spring 8 is stretched and stores elastic potential energy. At this time, the connecting plate 302 drives the U-shaped frame 301 to swing around the axis. As the connecting plate 302 rises, the limiting rod 304 on the surface of the connecting plate 302 passes through the gap between two adjacent rollers in the roller conveyor device 5, thereby blocking the tire being conveyed. Subsequently, when the eccentric block 404 continues to rotate to the lower position, the connecting plate 302 quickly returns to its original position under the rebound force of the tension spring 8, causing the U-shaped frame 301 to swing in the opposite direction. At this time, one end of the connecting block 303 of the U-shaped frame 301 descends and passes through the roller gap again through the limiting rod 304 on the surface of the connecting block 303, completing the blocking and releasing action. The gap between the connecting plate 302 and the connecting block 303 allows a tire to pass through, thereby realizing the individual separation and intermittent conveying of tires. When intermittent feeding of tires of different sizes is required, the user slides the positioning rod 9 on the connecting block 303 into the appropriate position inside the U-shaped frame 301 according to the size of the tire. During the adjustment process, the positioning groove 10 on the surface of the positioning rod 9 aligns with the positioning groove 10 of the U-shaped frame 301, and the positioning rod 9 is fixed by inserting the positioning pin 11, thereby locking the position of the connecting block 303. With the operation of the roller conveying device 5,This will cause the tire between the connecting plate 302 and the connecting block 303 to move. When the tire leaves the blocking position of the connecting block 303, the user starts the second motor 15 through an external control switch. The output end of the second motor 15 drives the gear 16 to rotate. The gear 16 will move along the path of the rack 12. As the gear 16 rolls, the sliding block 14 installed inside the bracket 6 moves synchronously and is guided by the slide rod 13 to ensure that the sliding block 14 remains stable during the movement. When the sliding block 14 moves to the position of the tire on the surface of the roller conveyor 5, the third motor 19 is started through an external control switch. The output end of the third motor 19 drives the tire to rotate. The rotating threaded rod 18 causes the movable plate 20 to move downwards. The mounting rod 17 guides the moving plate 20, which in turn moves the gripper device 2 downwards, clamping the tire. After clamping, an external control switch controls the output of the third motor 19 to rotate in the opposite direction, moving the movable plate 20 upwards and causing the tire held by the gripper device 2 to move upwards. Then, an external control switch controls the output of the second motor 15 to rotate in the opposite direction, moving the sliding block 14 to one side of the inner support device 1. Finally, the gripper device 2 places the tire on the surface of the inner support device 1, thus loading the tire.

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.
