Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and in particular relates to a tire retreading frame. Background Technology

[0002] Tires are ring-shaped elastic rubber products that are mounted on the metal rims of a vehicle body to support the vehicle body, buffer external impacts, and come into contact with the road surface. During the manufacturing process, when a tire is transported to the next process, a barcode scanning device is used to scan the barcode on the tire for work recording. If the barcode on the tire is facing down during transport, a tire flipping frame is needed to flip the tire over.

[0003] A tire turning frame, as disclosed in utility model patent CN216444490U, includes a first frame and a second frame arranged side-by-side. A set of conveyor rollers is mounted on the top of each frame. A turning bar is rotatably connected to the end of the first frame near the second frame. A cylinder for driving the turning bar to rotate is provided between the turning bar and the first frame. A set of receiving grooves is provided on the top of the first frame and the top of the second frame for the turning bar to fall into when it rotates to a horizontal position. A set of transverse limiting posts and a set of longitudinal limiting posts are provided on the top of the turning bar for limiting tire movement. This utility model can quickly turn tires and has the characteristics of high efficiency and high stability. However, in application, this technical solution requires resetting after turning one tire before turning the next, resulting in low turning efficiency, complex structure, and high maintenance costs. It suffers from technical problems in efficiently turning tires and facilitating equipment maintenance. Utility Model Content

[0023] Please see Figure 1-4 As shown, this utility model is a tire turning frame, including a first frame 3 and a second frame 10, and further including: a conveying roller 4 rotatably connected to the top end between the two sides inside the first frame 3 and the second frame 10, and the conveying roller 4 is arranged at equal intervals between the top end between the two sides inside the first frame 3 and the second frame 10; a drive motor 12 is provided at the rear end of the top end of one side of the first frame 3 and the second frame 10; the rear end of one side of the conveying roller 4 passes through the rear end of one side of the first frame 3 and the second frame 10 and is connected to the output end of the drive motor 12; a pulley 13 is provided on one side outside the conveying roller 4; and a transmission belt 14 is provided between the outer sides of the pulley 13. The drive motor 12 drives the conveying roller 4 to rotate, and the transmission belt 14 drives the pulley 13 to rotate synchronously, so that the conveying roller 4 can be driven to rotate in the same direction to input and output tires.

[0024] As a further implementation of this embodiment, such as Figure 1 and Figure 2 As shown, a positioning frame 1 is provided between the first frame 3 and the second frame 10. A drive shaft 6 is rotatably connected at the middle position of the top between the two ends inside the positioning frame 1. A direct drive motor 2 is provided at the top of the front end of the positioning frame 1. The front end of the drive shaft 6 passes through the top of the front end of the inner side of the positioning frame 1 and is connected to the output end of the direct drive motor 2. A flipping rod 5 is provided on the outside of the drive shaft 6, and the flipping rod 5 is arranged at equal intervals on the outside of the drive shaft 6. When flipping the tire, the drive shaft 6 is driven by the direct drive motor 2 to drive the flipping rod 5 to rotate 360° between the conveying rollers 4, so that the tires on the first frame 3 can be continuously flipped to the second frame 10. The structure is simpler, more durable and less prone to damage, thereby further improving the tire flipping efficiency and reducing the equipment maintenance cost.

[0025] When in use, the tires that need to be flipped are transported to the first frame 3 and then the direct drive motor 2 is started to drive the drive shaft 6 to drive a row of flipping rods 5 to lift the tires and flip them to the second frame 10, so that the tires are flipped. After the flipped tires are transported away, the next row of flipping rods 5 will lift the next tires and flip them, so that the tires on the first frame 3 can be flipped to the second frame 10 continuously.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, a buffer protection assembly is provided on one side of the bottom of the second frame 10 near both ends. The buffer protection assembly includes a cylinder 9, which is located on one side of the bottom of the second frame 10 near both ends. The cylinders 9 are parallel to each other. A telescopic rod 11 is inserted into the top of the cylinder 9. The top of the telescopic rod 11 passes through the conveyor rollers 4. A groove 7 is provided at the top of the telescopic rod 11. A guide roller 8 is rotatably connected between the two sides of the groove 7 near the top. When the tire is flipped onto the second frame 10 and falls, it is caught by the guide roller 8. A connecting piece 16 is provided in the cylinder 9 at the bottom end of the telescopic rod 11. A damping spring 15 is provided at the bottom end of the cylinder 9. The top of the damping spring 15 is fixedly connected to the bottom of the connecting piece 16. The damping spring 15 reduces the impact force generated by the falling tire and avoids damage to the conveyor rollers 4 due to excessive impact force, so as to achieve the purpose of buffering and protecting the conveyor components of the tire flipping frame.

[0027] Working principle: When using the tire flipping frame, firstly, the drive motor 12 on the first frame 3 is started to drive the conveyor roller 4 to rotate, and the belt 14 drives the pulley 13 to rotate synchronously. This drives the conveyor roller 4 to rotate in the same direction and input the tire onto the first frame 3. Then, the direct drive motor 2 is started to drive the drive shaft 6 to drive a row of flipping rods 5 to lift the tire and flip it onto the second frame 10, so that the tire is flipped. When the tire is flipped onto the second frame 10 and falls, it is caught by the guide roller 8. The damping spring 15 reduces the impact force generated by the tire falling. Then, the drive motor 12 on the second frame 10 is started to drive the conveyor roller 4 to rotate, and the transmission structure drives the conveyor roller 4 to rotate in the same direction to transport the tire. After the flipped tire is transported away, the next row of flipping rods 5 lifts up the next tire and flips it, so that the tires on the first frame 3 can be continuously flipped onto the second frame 10.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
