Its main function is to change the size and shape of the metal billets by rolling and stretching them to meet the required manufacturing requirements. In the processing of metal products, the calender is widely used in processing various industrial metal plates, pipes, wires, strips and various special-shaped profiles.

[0003] Chinese patent CN217021162U proposes an easily adjustable rubber calender, which solves the problem that it is inconvenient to adjust the spacing between the top pressure roller and the bottom pressure roller during the use of the rubber calender, thereby adjusting the processing thickness of the rubber film and reducing the processing range of the rubber calender.

[0021] It should be noted that the left-right rotating ball screw 17 is composed of a left-right rotating screw and two nuts. When the left-right rotating screw rotates, the two nuts can be driven to move relative to or away from each other.

[0022] Specifically, when metal materials of different widths are loaded, the hand wheel 7 is turned to operate the left-right rotating ball screw 17, thereby driving the left and right supporting platforms 16 to move relative to or away from each other, and the supporting wheel 15 is moved inside the roller slide rail 14, so as to adjust the distance between the left and right narrow belt conveyors 8. After placing different materials, the heater 19 is started so that the top and bottom of the metal material can be heated evenly, thereby avoiding obstruction of the bottom of the metal material and improving the preheating efficiency and effect.

[0024] Among them, the setting of the stable slide rail 2 allows the calendering mechanism to be effectively limited, making the operation more stable, and the setting of the protective shell 12 allows the metal material to be protected as much as possible during the transportation and loading process.
