[0003] In the related art, reference can be made to the Chinese utility model patent with authorization announcement number CN210287961U, which discloses a calendering machine, including a base, a square hole is provided on the base, and a movable plate and a hydraulic cylinder are provided in sequence in the square hole, and the movable plate is movably arranged in the guide groove on both sides, the cylinder body of the hydraulic cylinder is fixedly connected to the base, and the top of the piston rod is connected to the movable plate, and a bracket plate a is provided on the movable plate, and a mounting plate is provided on one side of the bracket plate a and an unwinding bracket plate is provided on the other side, and a calendering roller a is provided between the mounting plates, and one end of the calendering roller a passes through a bracket plate and is connected to the transmission shaft of the motor a, and the base is provided with two bracket plates b, and a calendering roller b is provided between the bracket plates b, and one end passes through the other bracket plate b and is connected to the transmission shaft of the motor b, and an unwinding roller is provided between the unwinding bracket plates, and both ends of the unwinding roller are rotatably connected to the unwinding bracket plates.

[0004] In the actual operation of the calender, different materials have different heat resistance due to their own material differences. When the calender is facing the calendering of different materials, the heating degree of the calender roller also needs to be adjusted accordingly. However, the above-mentioned calender cannot achieve calendering at the corresponding temperature for multiple materials, and its application range is relatively narrow. Summary of the Invention

[0005] In order to improve the calendering effect of the calender on the material, the present application provides a calender that is easy to control the temperature.

[0006] The present application provides a calender that is easy to control temperature, which adopts the following technical solutions:

[0007] A calender convenient for temperature control comprises a frame, a guide roller rotatably provided on the frame, and a calender roller vertically slidably provided above the guide roller, wherein the material to be calendered passes around the guide roller, a driving mechanism provided on the frame, the driving mechanism being used to drive the calender roller to move, and a heating device provided on the frame for heating the calender roller, the heating device comprising:

[0008] A heating block, wherein the heating block is disposed on the frame, the calendering roller is hollow, the heating block is located inside the calendering roller and contacts the inner side wall of the calendering roller, and the heating block and the calendering roller are both made of a resistive material;

[0012] By adopting the above technical solution, the material is transmitted around the guide roller, and the drive mechanism is started to drive the calendering roller to move. The calendering roller moves to press the material on the guide roller to perform calendering. At the same time, the calendering roller rotates as the material on the guide roller moves. The rotation of the calendering roller drives the rotation of the heating magnetic pole. The heating magnetic pole rotates in the heating coil, causing the heating coil to generate current. The heating block and the calendering roller form a whole that is equivalent to a large resistor. Therefore, after the heating coil generates current, the calendering roller and the heating block generate heat. At the same time, the friction between the rotation of the calendering roller and the heating block also generates heat, causing the calendering roller to heat up. The calendering roller squeezes the material and heats the material at the same time, improving the adhesion between the material and the calendering roller, so that the coating and substrate on the material can be better bonded, ensuring the calendering effect of the material. Then, the speed of the calendering roller is adjusted by the speed regulating mechanism, and the rotation speed of the heating magnetic pole can be adjusted, thereby adjusting the amount of current generated by the heating coil and the heating degree of the calendering roller. This makes the calendering roller adaptable to a variety of different materials and expands the scope of use of the calendering roller.

The change in the speed of the guide roller drives the speed of the calendering roller to change. The change in the speed of the calendering roller drives the speed of the heating pole in the heating coil to change, thereby causing the current generated by the heating coil to change accordingly, thereby adjusting the heat emitted by the calendering roller.
