[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1 to 10 As shown, this embodiment provides an automatic spare tire blocking and release turning machine, including a frame 1, a turning frame 2 rotatably connected to the top surface of the frame 1, a turning drive component 3 drivingly connected to the turning frame 2, the turning drive component 3 being mounted on the frame 1, feeding roller assemblies symmetrically arranged on the upper and lower sides of the turning frame 2, feeding roller assemblies drivingly connected to a feeding drive component 4, the feeding drive component 4 being mounted on the turning frame 2, gripper components symmetrically installed on the upper and lower sides of the turning frame 2, two gripper components located outside the feeding roller assemblies, and two gripper components drivingly connected to an opening and closing component.

[0030] The present invention uses a flipping drive component 3 to drive a flipping frame 2 to flip the wheels. The gripper component prevents the wheels from falling out of the flipping frame 2 during the flipping process. The purpose of the opening and closing component is to open the gripper component after the flipping frame 2 is flipped 180 degrees. After the gripper component is opened, the feeding drive component 4 can drive the feeding roller assembly to send the wheels out of the flipping frame 2. The entire structure eliminates the starting part and adopts a mechanical drive method, avoiding the entanglement of air pipes, thus making it more convenient to use.

[0031] In this embodiment, the feeding drive component 4 and the tilting drive component 3 can be driven by an electric motor or a servo motor combined with a reducer. The specific driving principle is existing technology and will not be described in detail here. The motors used in the feeding drive component 4 and the tilting drive component 3 are electrically connected to a controller, which can be a PLC controller.

[0032] In a further optimized design, flipping shafts 6 are fixedly connected to both sides of the flipping frame 2. The flipping shafts 6 are rotatably connected to the frame 1, and the output shaft of the flipping drive component 3 is shaft-connected to one of the flipping shafts 6.

[0033] The further optimized scheme includes a feeding roller assembly comprising several feeding rollers 7, which are rotatably connected to the tilting frame 2. One end of the feeding roller 7 is shaft-connected to a second sprocket 701, and the output shaft of the feeding drive component 4 is shaft-connected to a first sprocket 401. The first sprocket 401 and several second sprockets 701 are connected by a chain 8 for transmission.

[0034] The controller controls the operation of the feeding drive component 4, which can drive the first sprocket 401 to rotate. The first sprocket 401 drives the chain 8 to transmit power to the second sprocket 701, and then the second sprocket 701 transmits power to the feeding roller 7, causing the feeding roller 7 to rotate. By controlling the forward and reverse rotation of the feeding drive component 4, the wheels on the tilting frame 2 can be sent out.

[0035] In a further optimized design, a chain support block 201 is fixedly connected to the inner side of the tilting frame 2, and the chain support block 201 and the second sprocket 701 are located on the same side.

[0036] The purpose of setting the chain support block 201 is to support the chain 8 and prevent the chain 8 from falling off.

[0037] Further optimization of the scheme: the gripper component includes two symmetrically arranged grippers 5. The ends of the grippers 5 that are close to each other are fixedly connected to a gripper shaft 501. The two ends of the gripper shaft 501 are respectively fixedly connected to meshing gears 502. The meshing gears 502 at the ends of the two grippers 5 mesh with each other. The opening and closing component is connected to the gripper shaft 501 for transmission.

[0038] The two gripper shafts 501 on the same side mesh with each other through the meshing gear 502. When one gripper shaft 501 rotates, the other gripper shaft 501 will rotate accordingly, which can drive the gripper 5 to open or close.

[0039] The scheme is further optimized. The opening and closing components include opening and closing swing arms 9. One opening and closing swing arm 9 is rotatably connected to each end of the flipping shaft 6. The two opening and closing swing arms 9 are centrally symmetrically arranged. One end of the opening and closing swing arm 9 is rotatably connected to one end of the connecting rod 902. The other end of the connecting rod 902 is rotatably connected to one end of the rocker arm 903. The other end of the rocker arm 903 is axially connected to one of the gripper shafts 501 on the corresponding side. The other end of the opening and closing swing arm 9 is fixedly connected to the limit post 904. The frame 1 is fixedly connected to the limit block 905. The limit post 904 and the limit block 905 are in a limiting fit. One end of the return spring 901 is hooked on the flipping frame 2. The other end of the return spring 901 is hooked to the opening and closing swing arm 9.

[0040] As the entire tilting frame 2 rotates, the opening and closing swing arm 9 rotates together with the tilting frame 2 under the tension of the return spring 901. When the limiting post 904 contacts the limiting block 905, the opening and closing swing arm 9 stops rotating, while the tilting frame 2 continues to rotate. At this time, a relative angle difference will be generated between the opening and closing swing arm 9 and the tilting frame 2. The opening and closing swing arm 9 will drive the connecting rod 902, and under the force of the connecting rod 902, it will push the rocker arm 903 to rotate relative to the tilting frame 2, thereby driving the gripper shaft 501 to rotate relative to it. The gripper shaft 501 will drive the gripper 5 to open. At this time, the feeding drive component 4 is controlled to operate, utilizing... The feeding roller 7 delivers the wheel out. After the wheel is delivered, the next wheel enters. If the wheel does not need to be rotated, the feeding drive component 4 is controlled to deliver the wheel out. If it needs to be rotated, the controller controls the rotation drive component 3 to rotate in the opposite direction. After the rotation drive component 3 rotates in the opposite direction, the relative angle difference between the opening and closing swing arm 9 and the rotation frame 2 gradually decreases as the rotation frame 2 rotates in the opposite direction. Under the force of the return spring 901, the opening and closing swing arm 9 drives the gripper 5 to close. The other opening and closing swing arm 9, in the same state as described above, will drive the gripper 5 to open after it is rotated to the correct position. This achieves repeated rotation multiple times.

[0041] To further optimize the design, a limit detection component is installed on the frame 1. The limit detection component is installed on the side away from the flip drive component 3. The limit detection component includes an angle swing arm 1002 fixedly connected to the end of the flip shaft 6. A trigger post 1003 is fixedly connected to the side of the angle swing arm 1002. Two travel limit switches 1004 are installed on the frame 1. The two travel limit switches 1004 are located on both sides of the flip shaft 6. The trigger post 1003 contacts one of the travel limit switches 1004 every 180° of flipping.

[0042] The travel limit switch 1004 is electrically connected to the controller and is mainly used to detect whether the tilting frame 2 has tilted into place. When the tilting frame 2 tilts into place, the trigger post 1003 presses the travel limit switch 1004. At this time, the travel limit switch 1004 transmits a signal to the controller, and the controller controls the tilting drive component 3 to stop running.

[0043] The scheme is further optimized by installing an angle detection component on the frame 1. The angle detection component and the limit detection component are located on the same side and away from the flipping shaft 6. The angle detection component includes a mounting plate 10 fixedly connected to the frame 1. Several proximity switches 1001 are installed on the mounting plate 10. The proximity switches 1001 are evenly spaced around the circumference and are located on the circumference of the trigger post 1003.

[0044] The proximity switch 1001 is electrically connected to the controller. The proximity switch 1001 is mainly used to detect the rotation angle of the trigger post 1003, which is used to monitor the flipping status of the flipping frame 2.
