[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the inner tube is tested, the inner tube is first placed under the pressure wheel disc, and the electric push rod drives the pressure wheel disc to move downward during the process of the inner tube being inflated, so that the inner tube is completely immersed in the transparent detection barrel. At this time, the operator can directly observe whether there are bubbles in the transparent detection barrel, so as to detect the leakage of the inner tube, thereby improving the convenience and efficiency of the inner tube leakage detection.

[0017] When the inner tube is inspected, the inner tube will be immersed in the transparent inspection barrel. At this time, the air nozzle of the inner tube will drive the tire air nozzle clamping mechanism to move downward. The tire air nozzle clamping mechanism drives the adjusting column to squeeze the spring part through the connecting plate. In this process, the elastic coefficient of the spring part is smaller than the elastic coefficient of the reset spring. When the inner tube is evacuated, the spring part will generate elastic force on the adjusting column, so that the tire air nozzle clamping mechanism is reset, thereby avoiding the phenomenon that the air nozzle is damaged when the inner tube is immersed in the transparent inspection barrel, and improving the protection effect of the inner tube during the inspection process;

[0018] When the inner tube is inflated or deflated, the air nozzle of the inner tube is first inserted into the tire air nozzle clamping mechanism. At this time, the trumpet-shaped clamping plate in the tire air nozzle clamping mechanism will clamp the air nozzle, and the return spring will generate a rebound force on the trumpet-shaped clamping plate, thereby improving the firmness of the trumpet-shaped clamping plate when clamping the air nozzle, and speeding up the speed of disassembling and assembling the inner tube air nozzle, reducing the labor intensity of the operator when inspecting the inner tube;

[0019] After the inner tube is inspected, the air nozzle of the inner tube is pulled out from one tire air nozzle clamping mechanism and inserted into another tire air nozzle clamping mechanism. The controller then controls the second solenoid valve to open and controls the air pump to operate. At this time, the air pump will draw air into another hose through the air suction pipe, and the hose will then draw the gas in the inner tube through another tire air nozzle clamping mechanism, thereby speeding up the speed of inflation and deflation of the inner tube during inspection and improving the efficiency of the inner tube during production inspection.

[0020] When the inner tube is taken out of the transparent inspection barrel after inspection, the hot air blower will directly blow air on the inner tube, thereby accelerating the drying speed of water attached to the surface of the inner tube, thus avoiding the phenomenon that the inner tube cannot be quickly packaged after inspection.

When the inner tube is tested, the inner tube is first placed under the pressure wheel disc 14. When the inner tube is inflated, the electric push rod 13 drives the pressure wheel disc 14 to move downward, so that the inner tube is completely immersed in the transparent detection barrel 11. At this time, the operator can directly observe whether there are bubbles in the transparent detection barrel 11, so as to detect the leakage of the inner tube, thereby improving the convenience and efficiency of the inner tube leakage detection.

[0032] It is worth noting that two sleeves 16 are installed on one side of the upper surface of the transparent detection barrel 11, and the inside of the two sleeves 16 is connected to an adjustment column 18 through a spring member 17.

During this process, the elastic coefficient of the spring member 17 is less than the elastic coefficient of the reset spring 33. When the inner tube is deflated, the spring member 17 generates elastic force on the adjusting column 18, so that the tire air nozzle clamping mechanism 2 is reset, thereby avoiding the phenomenon that the air nozzle is damaged when the inner tube is immersed in the transparent detection barrel 11, and improving the protection effect of the inner tube during the detection process;

One end of the return spring 33 is fixedly connected to the inner wall of the tire air nozzle clamping mechanism 2, and the other end of the return spring 33 is fixedly connected to one side of the trumpet-shaped clamping plate 34. The two trumpet-shaped clamping plates 34 are symmetrically installed on both sides of the tire air nozzle clamping mechanism 2. When the inner tube is inflated or deflated, the air nozzle of the inner tube is first inserted into the tire air nozzle clamping mechanism 2. At this time, the trumpet-shaped clamping plate 34 in the tire air nozzle clamping mechanism 2 will clamp the air nozzle, and the return spring 33 will generate a rebound force on the trumpet-shaped clamping plate 34, thereby improving the firmness of the trumpet-shaped clamping plate 34 when clamping the air nozzle, and speeding up the speed of disassembling and assembling the inner tube air nozzle, reducing the labor intensity of the operator when inspecting the inner tube;
