[0031] Among them, the second fan 18 and the air guide 15 can be used to introduce harmful gases generated after drying into water for cooling and filter them through the coolant 16, thereby reducing the trouble and harm caused by the high temperature and harmful substances of the drying gas to the surrounding operators.

[0032] In this embodiment, the bottom of the drying box 1 is provided with a vent 17 that is connected to the interior of the water tank 6; a second fan 18 is provided at the vent 17; a housing 11 of the second fan 18 is provided with threads; the air guide member 15 includes an air guide cover 19 that is threadedly engaged with the second fan 18; the air guide cover 19 is conical and is connected to the second fan 18 at its larger end, and an exhaust pipe 20 that can extend into the coolant 16 is fixed at the other end;

[0033] Among them, the first fan 4 and the second fan 18 are both composed of a cylindrical shell 11, a motor and fan blades are arranged inside the shell 11, the end of the shell 11 of the second fan 18 is provided with a thread, and the end of the wind guide cover 19 is provided with an internal thread that cooperates with the thread of the second fan 18; the wind force of the second fan 18 needs to ensure that the gas it outputs can enter the coolant 16, so that the pressure inside the air guide 15 is greater than the pressure inside the coolant 16, so that the gas can enter the coolant 16 and be discharged.

[0034] The air guide cover 19 can be quickly assembled and disassembled by threaded engagement with the housing 11 of the second fan 18 , thereby facilitating cleaning.

[0035] In this embodiment, the air guide 15 further includes a plurality of telescopic tubes 21 ; the plurality of telescopic tubes 21 are telescopically and sealedly connected to each other, and the telescopic tubes 21 at the ends are telescopically and sealedly connected to the exhaust pipe 20 .

[0036] Among them, the length of the entire air guide 15 can be increased by using multiple telescopic tubes 21 that are sealed and telescopically connected to each other. When the water level in the water tank 6 is low, the gas generated by drying can still be introduced into the water, and the telescopic tubes 21 connected to each other can be telescopically folded to reduce the occupied space; among them, the diameters of the multiple telescopic tubes 21 increase successively, and telescopic sealing is achieved by sealing parts such as sealing rings 22, and the largest end extends into the exhaust pipe 20 for a sealed and telescopic fit.

[0037] In this embodiment, the air outlet 14 is opened at the top of one side of the water tank 6; a sealing plate 7 is provided at the bottom of the air outlet 14, a sealing ring 22 is provided at the sealing plate 7 to cooperate with the air outlet 14, and a filter 8 is provided above the sealing plate 7.

[0038] Among them, through the sealing plate 7 and the filter 8, the sealing plate 7 can seal the bottom area of ​​the air outlet 14 to prevent the water level from overflowing from the air outlet 14 due to being too high. At the same time, through the setting of the sealing plate 7, more water, namely coolant 16, can be added to the water tank 6 to increase the cooling time and reduce the replacement frequency.

[0039] In this embodiment, the length of the telescopic tube 21 is shorter than that of the exhaust pipe 20 , and the total length of the air guide cover 19 and the exhaust pipe 20 is shorter than that of the air outlet 14 .

[0040] Among them, by setting the length of the telescopic tube 21, the multiple telescopic tubes 21 have only the length of one telescopic tube 21 after being telescoped and folded, and the telescopic tube 21 can be extended into the exhaust pipe 20. When the air guide member 15 is removed, the entire air guide member 15 only has the length of the air guide cover 19 and the exhaust pipe 20, so that the air guide member 15 can be easily entered and exited from the air outlet 14.

[0041] In this embodiment, the heating element 3 includes a shell 11 connected to the top of the drying box 1 ; a plurality of heaters 10 are provided inside the shell 11 ; and a first fan 4 is provided on the top of the shell 11 .

[0042] Wherein, by arranging the heater 10 and the first fan 4, the hot air from the heater 10 can be blown into the drying chamber 13 to dry the printed cartons.

[0043] In this embodiment, doors 2 for sealing the drying chamber 13 are provided on both sides of the drying box 1 , and a conveyor belt 9 is provided between the two doors 2 .

[0044] The conveyor belt 9 can facilitate two operators standing at the two box doors 2 to operate in an assembly line manner, thereby improving efficiency.

[0045] Working principle: When drying, open one side door 2 and place the printed cartons at one end of the conveyor belt 9, start the first fan 4 and the heating element 3, and the first fan 4 blows the hot air from the heating element 3 into the drying chamber 13 to dry the printed cartons; at the same time, turn on the second fan 18 of the cooling component 5, and the second fan 18 blows the harmful gas generated by drying into the water tank 6, and at the same time blows the air flow into the water through the air guide cover 19. The gas is filtered and cooled by the water and enters the area above the water tank 6 where there is no coolant 16, and is finally further filtered and discharged through the filter 8. The discharged gas is cooled and filtered twice, which reduces the trouble caused by high temperature to the operator.
