[0026] In this embodiment, the transmission member 2 is used to transport the tiles so that the tiles move in the tube body 1. When the air pump 7 is working, the air is exhausted toward the space between the two screw plates 6 in the bottom shell 3, and the air flow is ejected through the corresponding nozzles 4 and blows toward the tiles from bottom to top to cool the tiles.

[0027] When the exhaust range of the nozzle 4 does not match the width of the tile, the screw 5 is rotated to drive the two screw plates 6 to move in the opposite direction, thereby adjusting the distance between the two screw plates 6, and then adjusting the width of the air outlet to adapt to the width of the tile, which not only ensures the cooling effect of the tile, but also avoids ineffective air outlet, thereby improving the applicability of the device.

[0028] Obviously, the ceramic tile should be located at the center of the transmission member 2 when discharged from the kiln, that is, the front and rear center planes of the ceramic tile and the front and rear center planes of the bottom shell 3 are coplanar.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, the transmission member 2 includes two roller conveyor belts 21 fixedly connected to the tube body 1 , the tiles are located on the top of the roller conveyor belts 21 , and a reversing portion 22 is provided between the two roller conveyor belts 21 .

[0030] In this embodiment, the roller conveyor 21 does not hinder the airflow from blowing toward the tile from below. The reversing portion 22 is used to flip the tile so that both the upper and lower sides of the tile are blown by the airflow, thereby improving the cooling uniformity of the tile.

[0031] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the reversing portion 22 includes a rotating rod 23 rotatably connected to the tube body 1, one end of the rotating rod 23 extends to the outside of the tube body 1, a driving member 24 is provided on one side of the tube body 1, and a rotating drum 25 is fixedly sleeved on the outer circumference of the rotating rod 23 located inside the tube body 1.

[0032] In this embodiment, in the initial state, the two placement grooves 26 are in a horizontal state. The tiles will automatically slide into the corresponding placement grooves 26 when moving on the roller conveyor belt 21, and then the driving member 24 will drive the rotating rod 23 to rotate 180 degrees, so that the two placement grooves 26 exchange positions, and the tiles are flipped and slide onto the other roller conveyor belt 21, realizing the reversal of the tiles.

[0033] In a further preferred embodiment of the present invention, Figure 1 As shown, the driving member 24 includes a servo motor fixedly connected to the side wall of the tube body 1, the output end of the servo motor is transmission-connected with a driving gear, and the outer circumference of the rotating rod 23 is fixedly sleeved with a driven gear, and the driving gear is meshed with the driven gear.

[0034] In this embodiment, the servo motor drives the output end to rotate 180 degrees each time it works. The servo motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the rotating rod 23 to rotate, so that the tile is turned over.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, a water tank 8 is placed on one side of the tube body 1, water is added to the water tank 8, a heat pipe 9 is fixedly penetrated through the top of the tube body 1 above the bottom shell 3, the heat pipe 9 is fixedly passed through the water tank 8, and the heat pipe 9 is spirally arranged in the water tank 8, and a faucet 10 is fixedly connected to the lower half of one side of the water tank 8.

[0036] In this embodiment, after the exhaust air from the nozzle 4 blows toward the ceramic tile, it takes away the heat of the ceramic tile and moves upward, enters the heat pipe 9 and passes through the water tank 8, performs heat exchange with the water in the water tank 8, heats the water, and thus fully utilizes the thermal energy. When hot water is needed, open the faucet 10 to drain the water. A top cover (not shown) is hinged on the top of the water tank 8, and the staff can open the top cover to add water to the water tank 8. The part of the heat pipe 9 located in the water tank 8 is made of copper material, and the heat exchange effect is better. The heat pipe 9 is located in the water tank 8 in a spiral shape, which increases the heat exchange time between hot air and water, thereby further fully utilizing the thermal energy in the hot air.

[0037] In a further preferred embodiment of the present invention, Figure 3 As shown, a collecting hopper 11 is fixedly connected to the top of the tube body 1 just above the bottom shell 3 , the collecting hopper 11 is communicated with the inside of the tube body 1 , and the heat conducting pipe 9 is fixedly passed through the top surface of the collecting hopper 11 and extends into the collecting hopper 11 .
