[0012] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0013] Example 1

[0014] like Figs. 1-4 The device shown is a phase toothed pleating device, which includes a forming disc 2, a fixing plate 5, and pleating teeth 7.

[0015] The forming disc 2 is mounted on the frame 1 and driven to rotate by a motor fixed on the frame 1. The forming disc 2 is provided with multiple forming rods 3 and pressure rollers 4 evenly distributed in a circle. The forming rods 3 and pressure rollers 4 correspond one-to-one and cooperate with each other. The forming rods 3 are driven to rotate by a power device. The driving method of the forming rods 3 is generally gear drive. The large gear is located on the side of the forming disc 2, and the forming rods 3 are provided with small gears. The large gear meshes with the small gears on each forming rod 3. When the forming disc 2 rotates under the drive of the motor, the forming rods 3 will revolve accordingly. At this time, the large gear will also rotate with the forming disc 2. When the large gear drives the small gear to rotate, the forming rods 3 rotate.
