The distance between the sliding seat (821) and the sliding seat (821) is adjusted by driving component eight; The support rotation mechanism (81) further includes: A lifting assembly (83), which is mounted on the support frame five (812), is used to drive the central tube (200) away from the support rod (813); The lifting assembly (83) includes: Drive component fourteen (831) is mounted on the support frame five (812); A lifting block (832) is mounted on the drive end of the drive member fourteen (831) and is movably positioned between two adjacent support rods (813); When the driving component fourteen (831) drives the lifting block (832) to extend between two adjacent support rods (813), the lifting block (832) moves to abut the lower end of the central tube (200), thereby driving the central tube (200) to disengage from the upper end of the support rod (813); The welding mechanism (9) includes: Welded beam (91), which is slidably mounted on the frame (1); A drive component 15 (92) is mounted on the frame (1), and the drive end of the drive component 15 (92) is movably connected to the welding beam (91) for driving the welding beam (91) to move on the frame (1); At least one set of welding components (93) is slidably disposed on the welding beam (91); At least one set of drive assembly six (94) is connected to the welding beam (91) and the corresponding welding assembly one (93) for driving the welding assembly one (93) to slide on the welding beam (91); Welding assembly two (95) is slidably disposed on the frame (1), and the welding assembly two (95) is movably inserted into the central tube (200) on the support rotation mechanism (81) and cooperates with the welding assembly one (93) to weld the mesh (100) onto the central tube (200); The welding assembly one (93) includes: Drive component sixteen (931) is mounted on the welded beam (91); The third electrode (932) is mounted on the driving end of the driving member sixteen (931); The third electrode (932) is driven to move and abut against the upper end of the mesh fabric (100) by the driving component sixteen (931); The second welding assembly (95) includes: Support frame six (951) is slidably mounted on the frame (1); The inner strut (952) is slidably mounted on the support frame six (951); The fourth electrode (953) is mounted on the inner support rod (952); Drive assembly seven (954), which connects the inner support rod (952) and the support frame six (951), is used to drive the inner support rod (952) to slide on the support frame six (951), so that the inner support rod (952) is inserted into the central tube (200), and with the cooperation of the third electrode (932) and the fourth electrode (953), the mesh (100) is welded to the central tube (200); The welding mechanism (9) also includes: A pusher assembly (96) is mounted on the welding assembly (93) or slidably mounted on the welding beam (91); The pusher assembly (96) includes: Drive component seventeen (961) is mounted on drive component six (94); A pusher plate (962) is mounted on the drive end of the drive component seventeen (961); When the drive component seventeen (961) drives the pusher plate (962) to move toward the center tube (200), when the pusher assembly (96) moves on the welding beam (91), the pusher plate (962) abuts against the rear end of the center tube (200), thereby pushing the center tube (200) toward the gripper chuck (823) of the rotating assembly (82); The clamping mechanism (84) includes: A flap (841) is hinged at its rear end to the frame (1); A drive component eighteen (842) is mounted on the frame (1), and the drive end of the drive component eighteen (842) is hinged to the flap (841) for driving the front end of the flap (841) to move toward or away from the support assembly (811). Several rotating wheels (843) are hinged to the front end of the flap (841) for moving to abut against the mesh (100) and pressing the mesh (100) against the central tube (200) at the upper end of the support assembly (811); A clearance area (844) is provided between adjacent rotating wheels (843), and the welding mechanism (9) welds the mesh (100) onto the central tube (200) through the clearance area (844).
