[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a microwave printing and dyeing drying and color fixing device, including a frame 1, a microwave tunnel oven 2 set on the frame 1, and a flat fabric feeding device 3 and a flat fabric discharging device 4 located at the inlet and outlet of the microwave tunnel oven 2, respectively. An exhaust device 5 is set on the top of the microwave tunnel oven 2. Two pairs of first guide rollers 7 and second guide rollers 8 arranged in an inverted W shape are rotatably arranged inside the microwave tunnel oven 2. A rotating frame 10 is set below each of the two second guide rollers 8. A driving device 9 for driving the rotating frame 10 to rotate is fixed on the outer side of the microwave tunnel oven 2. The two rotating frames 10 are driven by a chain 6. A large toothed disc 11 is set on the rotating frame 10 and a loosening mechanism 12 that beats the fabric guided by the first guide rollers 7 and second guide rollers 8 under the action of the large toothed disc 11. An elastic guiding mechanism 13 that provides elastic support for the second guide rollers 8 is set inside the microwave tunnel oven 2.

[0026] Among them, such as Figure 3 As shown, the rotating frame 10 includes a main shaft and frame plates fixed to the outer sides of both ends of the main shaft. One end of the main shaft of the rotating frame 10 is fixed to the output end of the drive device 9. Sprockets 101 located on both sides of the rotating frame 10 are fixed on the main shaft of the rotating frame 10. The chain 6 drives the sprockets 101 on the two rotating frames 10. During the drying process, the drive device 9 works to drive the rotating frame 10 to rotate, which in turn drives the cloth loosening mechanism 12 between the frame plates on both sides of the rotating frame 10 to rotate circumferentially around the large gear plate 11.

[0027] like Figure 3 and Figure 5 As shown, a bushing 111 is fixed at the center of the large gear disk 11. The bushing 111 is fixed to the inner wall of the microwave tunnel oven 2.

When the loosening mechanism 12 between the frame plates on both sides of the rotating frame 10 rotates around the large gear disk 11, the loosening mechanism 12 between the frame plates on both sides can rotate continuously through the meshing of the small gears 122 at both ends of the driven shaft 121 with the two sprockets 101 on the main shaft of the rotating frame 10. Then, the rotating crossbar 124 performs a beating loosening treatment on the fabric guided between the first guide roller 7 and the second guide roller 8.
