[0043] As Figures 2-4As shown, the embodiment provides an automatic air suction machine for inner tube, which comprises: a positioning device 1 comprising a nozzle clamping device 11610 for clamping and positioning the nozzle body of the inner tube; an air core disengaging device 2 for disengaging the air core of the nozzle of the inner tube to open the nozzle; and an air suction device 3 comprising air suction clamps 31 provided with a pair of clamp pieces 311, an air suction channel 32 being formed between the pair of clamp pieces 311 for connecting the nozzle, and a vacuum connection hole 33 being provided on one side of the air suction channel 32. In operation, the air core disengaging device 2 opens the nozzle of the inner tube on the positioning device 1, and since the air suction clamps 31 are fixed on both sides of the nozzle of the inner tube, the air suction clamps 31 only need to be clamped, the pair of clamp pieces 311 hold the nozzle, and the air suction channel 32 formed between the pair of clamp pieces 311 is in communication with the nozzle for air suction, so that the air suction structure is in communication with the nozzle without additional displacement structure, thereby simplifying and optimizing the equipment structure and saving cost.

[0044] In some embodiments, as shown in Figure 3 and Figure 5 , the air core disengaging device 2 comprises an air core clamping device 100 and a cap clamping device 200 arranged around the air core clamping device 100, and the cap clamping device 200 is driven to rotate by a rotating device 230. It can be understood that the cap clamping device 200 clamps the cap of the nozzle, and under the driving of the rotating device 230, the cap is rotated and cooperates with the air core clamping device 100 clamping the air core of the nozzle to realize the rotation and disengagement of the cap and the clamping of the air core, so that the air suction device 3 is connected to the nozzle for air suction. At the same time, the air core clamping device 100 and the cap clamping device 200 arranged in a ring further improve the space utilization of the equipment, which is beneficial to reducing the volume of the equipment.

[0045] In some embodiments, as shown in Figure 3 and Figure 5 , the air core clamping device 100 and the cap clamping device 200 are driven to displace by the same stroke mechanism 300 and are driven to clamp by the same driving device 400. It can be understood that the air core clamping device 100 and the cap clamping device 200 need four sets of driving modules to realize clamping and displacement, and in the embodiment, only two driving modules of the stroke mechanism 300 and the driving device 400 are used, which not only reduces the cost of the equipment, but also is convenient to maintain and improves the reliability of the equipment.

The second tension rod 223 pulls the inner rotating member 222 and the tension sleeve 221 to move downward, the tension sleeve 221 pushes the lower part of the pair of clamping jaws 212 of the air cap clamping jaw 210 to turn outward, and since the middle part of the pair of clamping jaws 212 is in a hinged state, the upper part of the pair of clamping jaws 212 will clamp the air cap inward.

The sliding plate of the sliding table mechanism 61 is provided with a material taking clamp 62, and the rotating rack 63 is provided with a plurality of material placing rods 64 arranged in a circumferential direction. In operation, the material taking clamp 62 clamps the inner tire and places it on the material placing rod 64. It can be understood that the inner tire can be placed into the air suction station by the worker, and the inner tire is inflated and deflated. The unloading device 6 is used to unload the inner tire, which undoubtedly saves the labor demand and reduces the cost.

[0055] In some embodiments, as shown in Figure 1 The rotating table 71 is arranged on the rack 7, and a plurality of inner tire air suction stations 72 are arranged in a circumferential direction on the rotating table 71. A set of positioning devices 1, air core separation devices 2 and air suction devices 3 are arranged on each inner tire air suction station 72.
