[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 A boxboard calendering device comprises a supporting platform 1, an L-plate 2 whose bottom is fixedly connected to an electric hydraulic push rod 3 is welded to one side of the supporting platform 1, the telescopic part of the electric hydraulic push rod 3 is fixedly connected to a fixed platform 4 by screws, a lower opening shell 5 is welded to the top of the fixed platform 4, a bearing 6 for rotating a rotating shaft 7 is welded to one side of the lower opening shell 5, a threaded rod 8 threadedly connected to a threaded rod sleeve 21 on the outer wall is welded to one side of the rotating shaft 7, and the bottom end of the threaded rod sleeve 21 is fixedly connected to an electric cylinder 11 whose telescopic part is fixed to a pressing platform 12 by screws.

[0023] It should be noted that the utility model relates to a cardboard calendering device. The staff places the cardboard on the supporting platform 1. After the placement is completed, the built-in external power supply is connected to the electric hydraulic push rod 3, and the extension of the electric hydraulic push rod 3 is controlled by the controller of the electric hydraulic push rod 3. The electric hydraulic push rod 3 drives the fixed platform 4 to move downward. The fixed platform 4 drives the sliding block B18 to move downward through the vertical plate 20. The sliding block B18 slides downward along the guide rail B19, which can well maintain the linear movement of the fixed platform 4. The fixed platform 4 fixes one side of the cardboard downward. After that, the built-in battery power supply can be connected to the electric cylinder 11, and the extension and contraction of the electric cylinder 11 can be controlled by the remote control of the electric cylinder 11. The electric cylinder 11 drives the pressing platform 12 to move up and down, so as to adjust the smoothness of the flattening (the smoothness after pressing is adjusted by adjusting the amplitude of the downward pressure). After that, the external power supply is connected to the motor 22 (the motor 22 is a bidirectional motor), and the forward rotation of the motor 22 is controlled by the control button of the motor 22. The machine 22 drives the rotating shaft 7 to rotate in the forward direction, the rotating shaft 7 rotates along the inside of the bearing 6, the rotating shaft 7 drives the threaded rod 8 to rotate clockwise, the threaded rod 8 drives the threaded rod sleeve 21 to move rightward, the threaded rod sleeve 21 drives the slider A10 to move rightward, the slider A10 slides to the right along the guide rail A9, and the threaded rod sleeve 21 drives the pressing table 12 to move rightward, thereby flattening the surface of the boxboard paper. Fixing one side of the boxboard paper first and then flattening it can well prevent the boxboard paper from shifting, and the flattening effect is good. The effect is better, and when hot pressing is needed, the cover 13 can be opened to pour water into the pressing platform 12, and the water is heated by the electric heating wire 14 (the bottom of the pressing platform 12 is made of heat-conducting material). The electric heating wire 14 heats the water, and the stirrer 15 can stir the water well to prevent uneven heating. After the heating is completed, hot pressing can be performed by the pressing platform 12, and the heated water can open the valve 17 and be taken out through the drain pipe 16 for use, so that the heat can be reasonably utilized and more energy-saving.
