It is only necessary to start the fan 20, and the fan 20 blows the wind toward the heating table 9 and the clamped roller through the air transmission pipe 21. Then, when it is necessary to prevent the roller from shifting during the heating process, it is only necessary to match the protrusion 23 and the groove 24, and limit the heat insulation cover 5 through the limit pin 25. The roller can be firmly placed in the heat insulation cover 5 through the hinge door 27 provided.

[0019] Working principle:

[0020] When it is necessary to clean the debris on the surface of the roller that has been heated in the heating equipment, first, the operator places the roller into the heat-insulating cover 5, and then the operator places the head and tail ends of the roller into the upper arc clamping plate 14 and the lower arc clamping plate 26 respectively. Then, the operator rotates the two screws 11, and the two screws 11 drive the two guide blocks 12 to move vertically respectively, and the two guide blocks 12 drive the two support blocks 13 to move respectively, and the two support blocks 13 drive the upper arc clamping plate 14 to move respectively. In this way, the roller is stabilized. Then, when one of the rollers is stabilized in the clamping mechanism, the operator starts the first motor 7, and the first motor 7 drives the first rotating shaft 8 to rotate. The first rotating shaft 8 rotates the other two fixed seats 10, and the two fixed seats 10 drive the two screws 11, the guide blocks 12 and the support blocks 13 to rotate at the same time. Similarly, the operator places the head and tail ends of the roller into the upper arc clamping plate 14 and the lower arc The two support blocks 13 are driven by the two support blocks 13 to move, and the two support blocks 13 are driven by the upper arc clamping plate 14 to move, until the head and tail ends of the roller are fastened in the upper arc clamping plate 14 and the lower arc clamping plate 26. After the clamping is completed, the operator starts the first motor 7 at a uniform speed, and the first motor 7 drives the first rotating shaft 8 at a uniform speed, and the first rotating shaft 8 drives the two clamping mechanisms to rotate at a uniform speed, and then starts the heating table 9, and heats the roller in the heat insulation cover through the heating table 9. After heating is completed, turn off the heating table 9, and then the operator will slide the heat insulation cover 5, and the heat insulation cover 5 will drive the brush 17 to continuously brush the roller debris located on the base 2. In this way, the debris generated by roller fatigue shedding can be cleaned, and it is ensured that the subsequent equipment will not be unable to perform heating processing due to a large amount of roller debris.

[0021] The waste box 18 can be used to continuously collect the debris that falls off the roller itself, and the fan 20 can be used to cool the roller when heating is completed. After cooling, the debris generated by fatigue shedding on the roller body can be blown away at the same time, and some scattered debris on the heating table 9 can also be blown onto the base 2 at the same time. It is only necessary to start the fan 20, and the fan 20 blows air to the heating table 9 and the clamped roller through the air transmission pipe 21. Then, when it is necessary to prevent the roller from shifting during the heating process, it is only necessary to match the protrusion 23 and the groove 24, and limit the insulation cover 5 by the limit pin 25. The hinge door 27 can be used to firmly place the roller in the insulation cover 5. The fan 20 can further increase the cleaning of the roller's own debris, and while cleaning the debris, it can also clean the debris on the heating table 9, and also reduce the accumulation of roller debris on the heating table 9, while increasing the efficiency of cleaning the debris on the base 2.
