The top of the flipping bracket 42 at the bottom is lower than the top of the first conveying roller 10, so as to achieve the sinking of the flipping bracket 42 at the bottom, thereby avoiding affecting the transportation of the tire embryo body 5.

[0020] See also Figure 2 The supporting bottom plate 30 is fixedly mounted on the top of the fixed bracket 13 , and the flip plate 40 is rotatably mounted on the middle of the top of the supporting frame 6 through the supporting shafts 46 at both ends.

[0021] See also Figure 2 and Figure 7 The positioning adjustment mechanism 2 includes a limit plate 24, one end of which is rotatably connected to a steering plate 25 via a hinge shaft, one side of the limit plate 24 is fixedly connected to a first fixed plate 27, and the side of the steering plate 25 close to the first fixed plate 27 is fixedly connected to a second fixed plate 28, and two bolt grooves 29 are provided through the top of the second fixed plate 28. The limit plate 24 and the steering plate 25 are respectively and evenly rotatably installed with guide rollers 26 on the side away from the first fixed plate 27.

[0022] Two positioning adjustment mechanisms 2 are symmetrically provided, and the first fixing plate 27 and the bolt slot 29 are respectively fixedly installed on the top of the top support plate 7. The bolt slot 29 is designed to be arc-shaped, and the arc center of the bolt slot 29 is the same as the center of the hinge axis, which is convenient for fixing the second fixing plate 28 after the steering plate 25 adjusts the angle. The guide rollers 26 on the two limiting plates 24 limit the tire embryo body 5, and the guide rollers 26 on the two steering plates 25 guide the tire embryo body 5 to move it between the two limiting plates 24.

[0023] Working principle: During use, first adjust the positioning adjustment mechanism 2 to limit the tire blank body 5, fix the first fixing plate 27 to the top of the top support plate 7 close to the end of the first servo motor 8 by bolts, so that the distance between the guide rollers 26 on the two limiting plates 24 matches the outer diameter of the tire blank body 5, and then rotate the steering plate 25 so that the guide roller 26 at the end of the steering plate 25 away from the limiting plate 24 is located at the end of the first conveying roller 10, and then fix the second fixing plate 28 by bolts passing through the bolt groove 29, and then start the first servo motor 8 to start the conveying, and the driving end of the first servo motor 8 drives the first transmission gear 16 to rotate The first transmission gear 16 drives the second transmission gear 18 to rotate through the transmission chain 17, and the rotation of the second transmission gear 18 drives the power shaft 15 to rotate, and the rotation of the power shaft 15 drives the first transmission wheel 19 to rotate, and the rotating first transmission wheel 19 drives the second transmission wheel 20 to rotate through the transmission belt 21, thereby driving the first conveying roller 10 and the second conveying roller 11 to rotate synchronously, and the article is transported from one end of the support frame 6 close to the first servo motor 8 to the other end of the support frame 6, and then the tire embryo body 5 is placed on the top of the first conveying roller 10 by external force, and the rotation of the first conveying roller 10 pushes the tire embryo body 5 to move to the other end of the support frame 6; When the embryo body 5 moves to the inner side of the arc-shaped limit plate 41, the second servo motor 9 is started to flip, and the driving end of the second servo motor 9 drives the rotating shaft 22 to rotate, and the rotation of the rotating shaft 22 drives the outer gear 23 to rotate, and the rotation of the outer gear 23 drives the inner gear 45 to rotate, and the rotation of the inner gear 45 drives the turntable 44 and the flip plate 40 to rotate synchronously, and the rotation of the flip plate 40 drives the flip bracket 42 to rotate, and the rotation of the flip bracket 42 drives the toggle plate 43 to move, and the movement of the toggle plate 43 pushes the baffle plate 33 to rotate upward, and the bottom end of the flip bracket 42 is away from the top of the lifting plate 34. At this time, the lifting plate 34 loses the pressure on the spring 37, and the spring 37 rebounds to push the lifting plate 34 to move upward, and the lifting plate 34 loses the pressure on the spring 37. The movement of the descending plate 34 drives the lifting bracket 38 to move upward, and because the toggle plate 43 drives the baffle plate 33 to rotate upward, the baffle plate 33 has an initial upward rotational force, and the lifting bracket 38 moves upward and drives the supporting roller 39 to move upward. When the supporting roller 39 is in close contact with the side of the baffle plate 33 close to the lifting bracket 38, the supporting roller 39 rolls upward on the baffle plate 33 and pushes the baffle plate 33 to continue to rotate upward until the side of the baffle plate 33 close to the positioning bar 32 is in close contact with the positioning bar 32. At this time, the baffle plate 33 and the supporting side plate 31 are in the same vertical plane. At this time, the baffle plate 33 can block the tire blank body 5 transported from the end of the support frame 6 close to the first servo motor 8; When the flip bracket 42 at the bottom rotates until the side of the flip bracket 42 close to the arc-shaped limit plate 41 is close to the bottom end of the tire embryo body 5, the flip bracket 42 pushes the tire embryo body 5 to flip, and when the flip plate 40 rotates 180 degrees, the second servo motor 9 stops. At this time, the tire embryo body 5 flips 180 degrees, and the flip bracket 42 located on the other side of the tire embryo body 5 is converted from the top to the bottom, and the bottom end of the flip bracket 42 is close to the top of the support frame 14, and the top of the flip bracket 42 is lower than the top of the second conveying roller 11, so that the tire embryo body 5 falls on The top of the second conveying roller 11, the rotation of the second conveying roller 11 pushes the embryo body 5 to continue to move toward the end of the support frame 6 away from the first servo motor 8. When the embryo body 5 moves to the end completely away from the flip bracket 42 away from the flip plate 40, the second servo motor 9 is started to reset, and the driving end of the second servo motor 9 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the internal gear 45 to rotate through the external gear 23, thereby driving the flip plate 40 to rotate 180 degrees to restore to the initial position. In the process of the flip plate 40 rotating and resetting, when it is close to the lifting plate 3 When the flip bracket 42 of 4 rotates to the top of the lifting plate 34, the flip bracket 42 presses the lifting plate 34 downward, and the lifting plate 34 is pressed downward by the flip bracket 42, and the movement of the lifting plate 34 drives the limiting slide bar 35 and the lifting bracket 38 to move downward synchronously. At the same time, the lifting plate 34 squeezes the spring 37 to contract, and the lifting bracket 38 moves downward to drive the supporting roller 39 to roll downward. When the flip plate 40 rotates 180 degrees to reset, the supporting roller 39 at the top rolls to the bottom of the baffle plate 33, and the baffle plate 33 loses support, and the bottom end of the flip bracket 42 Close to the top of the support frame 14, when the tire embryo body 5 is transported to the baffle plate 33, the baffle plate 33 loses support and is pushed by the tire embryo body 5 to rotate toward the side close to the lifting bracket 38, until the baffle plate 33 rotates 90 degrees and the supporting side plate 31 is in a vertical state. At this time, the baffle plate 33 is located on the inner side of the flip bracket 42, and the bottom end of the baffle plate 33 is close to the top of the toggle plate 43, and the top of the baffle plate 33 is lower than the top of the first conveying roller 10. The tire embryo body 5 loses the obstruction and moves toward the inner side of the arc-shaped limit plate 41, thereby performing a continuous flipping operation.
