[0002] After the waste tires are recycled, in order to ensure whether the waste tires meet the requirements of reprocessing and reuse, the waste tires need to be inspected to ensure whether the steel wire structure inside the tire body is damaged. If the steel wire structure inside the tire body is not damaged, it indicates that the tire meets the requirements of reprocessing and reuse. The existing tire inspection is mainly carried out through a tire X-ray inspection machine, such as a tire appearance inspection device integrated in a tire X-ray machine system with publication number CN206321587U. During the actual use of the above-mentioned inspection device, it is difficult to ensure that the detection mechanism and the tire position correspond to each other. When the detection mechanism and the tire position do not correspond (that is, when the detection head is located above the tire side), it will affect the normal progress of the inspection, and the tire position needs to be repeatedly adjusted manually, which is more troublesome. For the inspection of large quantities of waste tires, it will greatly reduce the inspection efficiency.

In combination with a rotating mechanism, it can provide a basic guarantee for comprehensive inspection of tires. Through an elastic self-adjusting mechanism, the movable frame can be coordinated with the tire body when the movable frame moves, thereby ensuring the relative position of the tire body and the X-ray detector, thereby ensuring the normal inspection of the tire body. In combination with a linked high-speed airflow cleaning mechanism, foreign matter on the surface of the waste tire body can be blown away and cleaned, thereby avoiding the adhesion of foreign matter on the surface of the tire body and affecting the inspection results. The specific contents are as follows:

[0015] 1. When inspecting the tire body, the X-ray inspection machine for used tires can adjust the position of the support rod by putting the tire body on the support rod and cooperating with the extension of the first cylinder and the transmission of the connecting rod, so as to install and fix the tire body. In the subsequent inspection process, the device can be supported and limited by the fixing ring, the limiting ring and the supporting plate to ensure the stability of the tire during the rotation inspection and avoid shaking of the device.

[0016] 2. When the waste tire X-ray detector is testing, the second cylinder can drive the fixed frame and the movable frame to move downward. Through the sliding action between the open structure at the lower end of the movable frame and the tire body, and the sliding action between the slider and the guide rod, the position adjustment of the movable frame and the X-ray detector can be achieved, ensuring that the X-ray detector and the tire body are perfectly matched, that is, the X-ray detector is located directly above the tire body, and the positioning plate and the ball bearing can be used to determine the distance between the tire body and the X-ray detector, ensuring the normal testing;

[0017] 3. During the tire inspection process, the waste tire X-ray inspection machine drives the half gear to rotate through the motor, and cooperates with the transmission effect between the half gear and the movable gear ring to make the fixed rod and the piston head slide in the cylinder. Cooperating with the action of the air inlet check valve and the air outlet check valve, the gas in the cylinder can enter the air distribution pipe through the conduit and be ejected at high speed through the nozzle. The high-speed airflow can effectively clean foreign matter on the surface of the tire body, thereby ensuring the cleanliness of the tire body, and then avoiding the adhesion of foreign matter on the tire body to affect the inspection result of the tire body.

The fixed frame 901 is fixed to the output end of the second cylinder 8. The guide rod 902 is fixed to the fixed frame 901. The movable frame 903 is arranged on the lower side of the fixed frame 901, and the lower end of the movable frame 903 is an inclined open structure. The upper end of the movable frame 903 is fixed to the slider 904. The slider 904 The slide block 904 is connected to the guide rod 902 in a sliding manner. One end of a spring 905 is fixed to the slide block 904. The other end of the spring 905 is fixed to the fixed frame 901. An X-ray detector 906 is fixed to the movable frame 903. A positioning plate 907 is also fixed to the movable frame 903 symmetrically. Ball bearings 908 are evenly installed on the lower end surface of the positioning plate 907. The ball bearings 908 can roll in contact with the tire body 7. When the tire is tested, the fixed frame 906 is driven by the second cylinder 8. 01 and the movable frame 903 move downward, cooperate with the open structure at the lower end of the movable frame 903, so that the movable frame 903 and the tire body 7 can contact and slide, cooperate with the sliding action between the slider 904 and the guide rod 902 and the elastic action of the spring 905, so that the movable frame 903 and the tire body 7 can be perfectly matched, that is, the X-ray detector 906 is located directly above the tire body 7 to ensure the accuracy of the detection, until the tire body 7 and the ball 908 are contacted to achieve positioning, thereby ensuring the distance between the tire body 7 and the X-ray detector 906, facilitating the detection, and through the rolling action of the ball 908, it is convenient to reduce the friction between the tire body 7 and the positioning plate 907 when the tire body 7 rotates, providing a basic guarantee for realizing the comprehensive detection of the tire body 7, and a cleaning mechanism 10 is arranged on the lower side of the movable frame 903; the movable frame 903 and the tire body 7 are nested and connected, and the maximum width of the opening at the lower end of the movable frame 903 is equal to the length of the support rod 608;

[0030] After the tire body 7 is installed and fixed, Figure 1 , Figure 5 and Figure 6As shown, by starting the second cylinder 8, the fixed frame 901 and the movable frame 903 can be driven to move downward. When the lower inclined edge of the movable frame 903 contacts and slides with the tire body 7, the movable frame 903 is forced to move. The sliding guide effect between the slider 904 and the guide rod 902 can ensure the stability of the movement of the movable frame 903, so that the position adjustment of the movable frame 903 and the X-ray detector 906 can be achieved until the tire body 7 contacts the ball 908.

The piston head 1004 is fixed on the fixed rod 1002, and the piston head 1004 is slidably connected to the cylinder 1003; an air inlet check valve 1005 is fixed on the cylinder 1003, and an air outlet check valve 1006 is also fixed on the cylinder 1003; the air outlet check valve 1006 is connected to the air distribution pipe 1007 through a conduit, and the air distribution pipe 1007 is fixed on the movable frame 903, and nozzles 1008 are fixed at equal intervals on the lower end surface of the air distribution pipe 1007;

[0032] During tire testing, Figure 1 and Figure 4As shown, during the rotation of the clamping mechanism 6 and the tire body 7 driven by the motor 4, the half gear 5 can be synchronously driven to rotate, and the meshing transmission effect between the half gear 5 and the movable gear ring 1001 can make the movable gear ring 1001 and the fixed rod 1002 move, and the sliding guide effect between the fixed rod 1002 and the fixed plate 3 can ensure the stability of the movement of the movable gear ring 1001 and the fixed rod 1002. When the fixed rod 1002 moves, the piston head 1004 is driven to slide in the cylinder 1003 at the same time. When the piston head 1004 slides toward the inside of the cylinder 1003, the air inlet check valve 1005 is closed and the air outlet check valve 1006 is opened, thereby realizing the exhaust effect of the cylinder 1003. When the piston head 1004 slides toward the outside of the cylinder 1003, the air inlet check valve 1005 is opened and the air outlet check valve 1006 is closed, thereby realizing the air suction effect of the cylinder 1003, and the gas discharged from the cylinder 1003 enters the gas distribution pipe 1007 through the conduit, and is ejected outward at high speed through the nozzle 1008. Through the action of high-speed airflow, foreign matter adhered to the surface of the tire body 7 can be cleaned, thereby ensuring that the surface of the tire body 7 is clean and avoiding foreign matter adhering to the tire body 7 and affecting the detection effect. In addition, the cylinder 1003 is provided with two groups, thereby ensuring that the nozzle 1008 can continuously eject high-speed airflow outward, thereby ensuring the normal operation of the device. This is the working principle of the waste tire X-ray detection machine.
