[0009] 1. The adjustment mechanism for the calendering roller structure can drive the first slider and the second slider to move in opposite directions along the slide rail by rotating the bidirectional screw rod, and can drive the first slide and the second slide to move synchronously on the inner side of the frame through the cooperation of the fixed pin and the support plate. The first slide and the second slide can drive the driven roller to move synchronously while the first slide and the second slide move, thereby adjusting the distance between the driven roller and the active roller. With this structure, only a set of threaded transmission structures needs to be installed under the driven roller to realize the synchronous movement of the two sides of the driven roller.

[0010] 2. The adjustment mechanism for the calendering roller structure enables the first slider and the second slider to slide on the surface of the slide rail while providing limited support for both, thereby reducing the force acting on the bidirectional screw rod, making it difficult for the bidirectional screw rod to bend when subjected to force. At the same time, the frame can be limited and supported through the cooperation of the limit rod, the first nut and the second nut, making it difficult for the frame to be deformed when subjected to force, thereby ensuring that the first slide and the second slide can stably move on the inner side of the frame.
