The second rotary clamping seat 4 is provided with a second rotary head 6 for connecting to and rotatingly driving the other end of the inflatable cabinet 100. The first rotary head 5 and the second rotary head 6 rotate synchronously. Thus, by synchronously rotating and driving the first rotary head 5 and the second rotary head 6 connected to both ends of the inflatable cabinet 100 on the rotary clamping machine 2, the left and right ends of the inflatable cabinet 100 rotate synchronously during welding, so as to eliminate the twisting force generated on the inflatable cabinet during the driving rotation, thereby achieving the purpose of continuous rotation welding, improving work efficiency and reducing the defective rate.

[0027] In this embodiment, see Figure 3 , also includes a first trip assembly 7 and a second trip assembly 8, which are arranged corresponding to the first rotary clamping seat 3 and the second rotary clamping seat 4. The first trip assembly 7 and the second trip assembly 8 both include a main shaft 9 and a trip 10 connected to both ends of the main shaft 9 and a connecting frame 11. The connecting frame 11 is an I-shaped structure. The connecting frame 11 is provided with a connecting hole 12 for connecting to the side of the inflatable cabinet 100, which is used to connect the inflatable cabinet 100. The trip 10 is detachably connected to the first rotating head 5 and the second rotating head 6. Specifically, a plurality of trip holes 13 are provided on the trip 10, and the first rotating head 5 and the second rotating head 6 are provided with a push pin 14 that can be inserted into or withdrawn from the trip hole 13.

In order to improve the positioning and clamping effect, the trip hole 13 is a symmetrically arranged conical hole, and the push pin 14 is a conical pin that cooperates with the conical hole 13, which can play a locking role after cooperation.

[0028] In this embodiment, the first rotating head 5 and the second rotating head 6 both include a hollow flange 15 and a hollow shaft 16, and the hollow flange 16 is fixedly connected to one end of the hollow shaft 16. The first rotating clamping seat 3 and the second rotating clamping seat 4 are also provided with a telescopic member 17, a push rod 18 and a push plate 19. The telescopic member 17 adopts a telescopic cylinder, and the telescopic end of the telescopic member 17 is connected to one end of the push rod 18, and the other end of the push rod 18 is slidably connected with the inner hole of the hollow flange 15 and the hollow shaft 16, and the push plate 19 is connected to the other end of the push rod 18. The push pin 14 is installed on the push plate 19. When the staff hoist the first tripping assembly 7 and the second tripping assembly 8 between the first rotating clamping seat 3 and the second rotating clamping seat 4, the tripping hole 13 is aligned with the push pin 14, and then the telescopic member 17 on the first rotating clamping seat 3 and the second rotating clamping seat 4 is extended, so that the push pin 14 is inserted into the tripping hole 13, thereby completing the positioning and clamping effect of the inflatable cabinet 100.

[0029] In this embodiment, in order to adapt to the continuous welding of inflatable cabinets 100 of different lengths, the rotary clamping machine 2 also includes a machine base 20, a first rotary drive member 21 that is synchronously driven with the hollow shaft 16 on the first rotary clamping seat 3 and the second rotary clamping seat 4, the first rotary drive member 21 adopts a motor with a reducer, and guide rails 22 are installed on both sides of the machine base 20 relative to each other. The second rotary clamping seat 3 is fixedly installed on the machine base 20, and the first rotary clamping seat 4 is slidably connected to the guide rails 22 in a manner that can slide relative to the second rotary clamping seat 20. Specifically, in order to achieve the reciprocating drive of the first rotary clamping seat 4, the rotary clamping machine 2 also includes a second rotary member 23, a screw rod 24 and a screw nut 25. The second rotary member 23 also adopts a motor structure. The second rotary member 23 is driven by the screw rod 24. The screw nut 25 is installed at the bottom of the first rotary clamping seat 4.
