[0023] In this embodiment, there are four corresponding adjustment side plates 9 and bases 11, which are evenly distributed around the center screw 6. A threaded hole is opened in the center of the adjustment seat 7, and the adjustment seat 7 is sleeved on the adjustment seat 7 through the threaded hole. When the center screw 6 rotates, the adjustment seat 7 is connected to the adjustment side plate 9 through the connecting rod 8, and the adjustment side plate 9 is embedded in the base 11 through the T-shaped slider 10. The base 11 is fixed relative to the rear turntable 5, so the adjustment seat 7 will not rotate. As the center screw 6 rotates and the adjustment seat 7 moves forward, the adjustment seat 7 pulls the adjustment side plate 9 downward through the connecting rod 8, thereby reducing the distance between the four adjustment side plates 9 and reducing the radius of the adjustment side plate 9, making it convenient to put on the air duct, and then rotate the center screw in the opposite direction. Rod 6, adjusts the inner wall of the side plate 9 to fit the inner side of the air duct, thereby fixing the air duct, a groove is opened in the inner cavity of the upper adjustment frame 16, and the sliding seat 17 extends into the groove to fix it to prevent the flanging structure 20 from falling, and the distance from the flanging structure 20 to the air duct is changed by adjusting the position of the height adjustment rod 19 in the sliding seat 17, and the position of the sliding seat 17 in the inner cavity is adjusted to align the flanging disk 21 in the flanging structure 20 with the required flanging position, the small motor 22 can drive the flanging disk 21 to rotate, and the main motor 15 can drive the front transmission disk 3 to rotate, the front transmission disk 3 drives the rear turntable 5 through the connecting column 4 and drives the entire installation structure and the air duct to rotate, the two rotating parts are in contact, and the flanging disk 21 is pressed down to flanging the edge of the air duct.

[0024] A fixed shaft 12 is disposed at the center of the front face of the adjusting side plate 9 , and a fixed side plate 13 is sleeved on the surface of the fixed shaft 12 .

[0025] In this embodiment, when the adjustable side panel 9 moves through the adjusting seat 7, the other fixed side panels 13 follow the adjustable side panel 9 through the fixed shaft 12, extending the length of the adjustable side panel 9, so that the adjustable side panel 9 cooperates with the fixed side panel 13 to clamp the air duct with a longer length, preventing the clamped adjustable side panel 9 from being too narrow and causing deformation of the air duct during flanging.

[0026] Wherein, a handle is installed on the front side of the central screw rod 6.

[0027] In this embodiment, the handle can facilitate the operator to rotate the central screw 6 to adjust the position of the side plate 9.

[0028] Among them, sliding rods 18 are arranged on the left and right sides of the height adjustment rod 19 .

[0029] In this embodiment, the top ends of the slide bars 18 are connected to prevent the flange structure 20 from falling off the slide seat 17 .

[0030] Two sliding seats 17 are installed inside the upper adjustment frame 16 .

[0031] In this embodiment, the two sliding seats 17 correspond to two sets of flanging structures 20, which are used to flanging the front and rear ends of the air duct at the same time, thereby improving the flanging efficiency.

[0032] Among them, a limited roller 14 is arranged between the two bases 11, and the distance from the front end of the limited roller 14 to the rear turntable 5 is smaller than the distance from the leftmost side plate 9 to the rear turntable 5.

[0033] In this embodiment, the air duct is inserted from the front of the device during installation, with one end moving forward until it contacts the limiting roller 14 for positioning. The distance between the limiting roller 14 and the adjusting side plate 9 is the flange position. After fixing the air duct, the flange plate 21 is used to press this point inward to complete the flange.

[0034] Working principle: the operator holds the handle and rotates the central screw 6, the adjustment seat 7 moves forward and pulls the adjustment side panel 9 downward through the connecting rod 8, thereby reducing the distance between the four adjustment side panels 9 and reducing the radius of the adjustment side panel 9, making it easier to put on the air duct and push the air duct to the position of the limit roller 14, and then rotates the central screw 6 in the opposite direction, the adjustment side panel 9 drives the fixed side panel 13 to open to fix the air duct, the air duct is driven to rotate by the main motor 15, and the rotation of the flanging disk 21 is started by the small motor 22, and the position of the sliding seat 17 in the upper adjustment frame 16 is adjusted until the flanging disk 21 is aligned with the edge of the air duct, and the height adjustment rod 19 is pressed down to make the flanging disk 21 contact the air duct for flanging.
