In addition, the guide 501 of this embodiment is preferably a slide rail or a slide rod, and in this embodiment, a cylindrical slide rod is preferably used, and correspondingly, the slide block 503 is slidably engaged with the slide rod. In addition, the end of the guide rod is provided with a stopper, and the slider 503 can be directionally moved along the guide 501 through the guide 501 without sliding deviation, so that the wing 504 can stably push the tire 70 to move, and the stopper can prevent the slider 503 from slipping off the guide 501.

In order to make the wing 504 push the tire 70 better, the wing 504 in this embodiment is bent to form a fixed portion for connecting with the slider 503 and a contact portion for contacting with the tire 70, wherein the contact portion is bent downward, and the included angle between the fixed portion and the contact portion is 30-150 °. The contact portion of the flap 504 can abut against the tire 70 in the unfolded state, and the included angle between the fixing portion and the contact portion is 30-150 degrees, within the range of the included angle, the contact portion can be guaranteed to contact the tire 70 to the maximum extent, and a better pushing effect is achieved.

In this embodiment, when the wing 504 rotates and retracts upward, the pulley 505 fits the highest position of the first inclined surface 5061 of the auxiliary 506, and the pulley 505 is farthest away from the fixing position of the wing 504 and the slider 503, when the fourth driving mechanism 508 pushes the slider 503 to slide forward along the guide 501, the slider 503 moves forward relative to the auxiliary 506, the wing 504 rotates downward due to its own weight, the pulley 505 is driven to slide forward and downward gradually along the first inclined surface 5061, after the pulley 505 slides away from the first inclined surface 5061, the slider 503 and the wing 504 move away from the auxiliary 506, the wing 504 is in a fully opened state, the free end of the wing 504 can directly contact the tire 70, and the fourth driving mechanism 508 continues to push the slider 503 together with the wing 504 to push the tire 70 to move forward. When the pulley 505 slides backwards along the first inclined surface 5061, the pulley 505 on the wing 504 gradually moves backwards to contact the auxiliary 506, then the pulley 505 moves backwards due to the gradually enlarged fixing positions of the pulley 505, the wing 504 and the slider 503 along the first inclined surface 5061 of the auxiliary 506, the wing 504 is folded upwards, when the pulley 505 slides to the highest position along the first inclined surface 5061 of the auxiliary 506, the wing 504 is in a completely folded state, and the tire 70 can be pushed into the tire 70 placing table from the lower part of the tire inlet 102 without influencing feeding.

Preferably, in this embodiment, in order to prevent the wing 504 from rotating due to its own weight and automatically rotating to the lower side to be in the folded state without a limit, the effect of pushing the tire 70 is not well stressed, and the wing 504 cannot be automatically folded upward without external force through the auxiliary 506 in the downward folded state, which would affect the transportation of the next tire 70. For this purpose, the tab 504 is also provided with a self-locking mechanism for limiting the angle of rotation. The implementation mode of auto-lock structure in this scheme has the multiple: the first self-locking structure comprises a protrusion arranged on the outer side wall of the sliding block 503 and a guide groove arranged at the joint of the wing 504 and the sliding block 503, wherein the protrusion abuts against the groove surface of the guide groove to limit the wing 504 to continue to rotate along the original rotation direction. Secondly, the two fins 504 are arranged on the two sides of the auxiliary part 506, the self-locking mechanism comprises a protrusion 507 arranged at the joint of the fin 504 and the sliding block 503, and the two fins 504 are abutted by the two protrusions 507 in the rotating process to limit the two fins 504 to continue to rotate along the original rotating direction.

Through the above-mentioned various self-locking modes, it can be ensured that the wing piece 504 can be limited and locked when rotating to a specified position or angle, at this time, the wing piece 504 cannot continue to rotate along the rotation direction, and the contact part of the wing piece 504 can contact the tire 70. Meanwhile, when the fourth driving mechanism 508 drives the sliding block 503 to move backward, the wing 504 can change from the flat state to the folded state.

Preferably, the fixing portion is bent backward in a zigzag shape so that the contact portion and the connection portion of the wing 504 and the slider 503 are not in the same straight line. The contact is now parallel to the connection of the wing 504 and slider 503, and the contact is behind the connection of the wing 504 and slider 503. When the tire 70 is placed at a position later than the wing 504, the wing 504 is in a horizontal state after being unfolded, and the contact part is relatively positioned at a position later than the connection position of the wing 504 and the sliding block 503, so that the tire 70 can be contacted in the forward pushing process, and the compatibility of the wing 504 pushing the tire 70 is improved.

Through the arrangement, the scheme can realize that the free end of the wing piece 504 can move up and down completely by self gravity without the power driving the wing piece 504 to move up and down and move in an opening and closing manner, so that the effect of pushing the tire 70 is achieved, the structure is simple and reliable, and energy is saved. In addition, the fourth driving mechanism 508 may be implemented by an electric motor, a hydraulic cylinder, or an air cylinder.
