[0026] Working principle of this utility model:

[0027] When the device is in use, the plate body 5 is inserted into the interior of the support seat 4 to achieve the installation of the plate body 5. After the plate body 5 is installed, the conveyor belt 1 drives the support shaft 3 to move, and the support shaft 3 drives the support seat 4 to move, thereby driving the plate body 5 to move, so that the plate body 5 moves into the heating cover 2. At this time, the air inlet fan 6 extracts and transports the outside air to the surface of the plate body 5. In this process, the air passes through the heat pipe 8 and completes heat exchange with the heat pipe 8. The heated air moves to the surface of the plate body 5 to achieve heating of the plate body 5. In this process, the support shaft 3 drives the transmission gear 9 to move horizontally, and the transmission gear 9 cooperates with the rack 10, so that the transmission gear 9 drives the support shaft 3 to rotate, and the support shaft 3 drives the support seat 4 to rotate, thereby driving the plate body 5 to rotate, so that the surface of the plate body 5 is heated evenly, thereby completing the heat treatment processing of the plate body 5;

When the bottom end of the plate body 5 contacts the middle of the two clamps 15, the plate body 5 squeezes the middle of the clamps 15, causing the two clamps 15 to move outward. At this time, the pin rod 14 moves in the slide groove 13. At this time, the plate body 5 can pass through the gap between the two clamps 15 and be fully inserted into the support seat 4. At this time, the spring acts on the clamps 15, causing the clamps 15 to rotate around the pin shaft. At this time, the upper part of the clamps 15 clamps the plate body 5. At this time, the installation of the plate body 5 can be completed. When removing the plate body 5, pull the plate body 5 upward to separate the plate body 5 from the clamps 15, and the removal of the plate body 5 can be completed.
