The follow-up monitoring mechanism 4 includes a floating module and a color change monitoring module.

The driven pressure wheel 42 is rotatably mounted on the moving plate 41. Two slide bars 43 are fixedly mounted on the moving plate 41. The slide bars 43 are limitedly slidably connected with the moving frame 214. Baffles are fixedly mounted on the ends of the two slide bars 43.
