The barrel needs to be inflated to ensure a certain pressure inside. This involves a series of complex operations such as fixing the barrel body, tightening the barrel connecting shaft, and inflating. In addition, after inflation, the barrel body needs to be cleaned. Currently, this is mostly done manually with the assistance of different equipment, involving the transfer between multiple devices, resulting in low processing efficiency. Furthermore, the barrels come in various sizes, with products of different outer diameters and lengths. How to ensure product compatibility is also a problem that needs to be solved.

Two sets of longitudinally distributed downward clamping assemblies (33) are mounted on the mounting plate (32), and two sets of laterally distributed clamping and gripping assemblies (34) are mounted on the mounting plate (35). 34) A cleaning assembly (35) is installed on the side end. The pressing clamping assembly (33) includes a pressing cylinder (331) installed on the mounting plate (32), upper and lower clamping jaws (332) driven to move by the pressing cylinder (331), and a linear guide rod (333) installed on the upper and lower clamping jaws (332). The linear guide rod (333) is guided through the mounting plate (32). The lower part of the upper and lower clamping jaws (332) is provided with a V-shaped groove for pressing clamping cylinder.

5. The barrel-connecting shaft screwing and gas-filling plasma cleaning equipment according to claim 4, characterized in that: The clamping and gripping assembly (34) includes a linear slide rail (341), a transfer plate (342), a bidirectional threaded screw (343), a gripping motor (344), and left and right gripping claws (345). Two linear slide rails (341) are installed on the lower surface of the mounting plate (32). Transfer plates (342) are installed on two sets of sliders on the linear slide rails (341). A bidirectional threaded screw (343) is also installed on the lower surface of the mounting plate (32). The two screw nuts of the bidirectional threaded screw (343) are fixedly connected to the transfer plate (342). The bidirectional threaded screw (343) is driven to rotate by the gripping motor (344). The rotation of the bidirectional threaded screw (343) drives the two transfer plates (342) to move relative to each other or in opposite directions. Two sets of opposing left and right gripping claws (345) are installed on the two transfer plates (342). V-grooves are provided on the opposing surfaces of the left and right gripping claws (345).

6. The barrel-connecting shaft screwing and gas-filling plasma cleaning equipment according to claim 5, characterized in that: The cleaning assembly (35) includes a lifting cylinder (351) mounted on the side of the transfer plate (342) and a plasma cleaning spray gun (352) driven by the lifting cylinder (351).

7. The barrel-connecting shaft screwing and gas-filling plasma cleaning equipment according to claim 1, characterized in that: The barrel transfer mechanism (5) includes a barrel transfer trolley (51) and a trolley positioning assembly (52) used in conjunction with the barrel transfer trolley (51). The barrel transfer trolley (51) includes a trolley (511), a portal frame (512) mounted on the trolley (511), and several sets of hook assemblies (513) mounted on the crossbeam of the portal frame (512). The hook assembly (513) is provided with two hooks for suspending the transverse pin on the barrel connecting shaft, and the distance between the two hooks is greater than the shaft diameter of the barrel connecting shaft. The trolley positioning assembly (52) includes a positioning frame (521), a guide block (522), and a right-angle positioning component (523). 3) Rotary clamping cylinder (524), clamping block (525) and proximity sensor (526). The positioning frame (521) has two guide blocks (522) installed at the front end and two right-angle positioning parts (523) installed at the rear end. The guide blocks (522) and right-angle positioning parts (523) form a directional opening for positioning the barrel transfer trolley (51). The lower end of the right-angle positioning part (523) is equipped with a rotary clamping cylinder (524). The rotary clamping end of the rotary clamping cylinder (524) is equipped with a clamping block (525). The outer end of the guide block (522) is equipped with a proximity sensor (526).
