the temperature sensing switch 5 detects the temperature in the furnace body 1, when the temperature reaches a set temperature, the second electric telescopic rod 13 is extended, the pinch roller 14 at the telescopic end of the second electric telescopic rod 13 descends and extrudes through the start-stop switch button on the timer 12, so that the timer 12 starts timing, namely, the time length of the refrigerator door for drying at the corresponding temperature is timed, when the temperature is lower than a set value in the drying process, the temperature sensing switch 5 feeds back a signal to enable the second electric telescopic rod 13 to contract, the pinch roller 14 rises and extrudes again through the start-stop switch button, so that the timer 12 pauses timing, when the temperature in the furnace body 1 reaches the corresponding temperature again, the timer 12 continues timing, thus the refrigerator door can be ensured to be dried at the corresponding temperature for a corresponding time length, so as to ensure that the drying and curing reach a certain degree, when the timer 12 times for a corresponding time length, when the first electric telescopic rod 31 extends, the first electric telescopic rod drives the strip-shaped plugging plate 6 to move and butt against the corresponding air outlet pipe head 7 to plug the strip-shaped plugging plate to enable the air pressure in the corresponding main air pipe 8 and auxiliary air pipe 9 to rise, when the first electric telescopic rod 31 contracts, the strip-shaped plugging plate 6 is separated from the corresponding air outlet pipe head 7, then the air flow boosted in the main air pipe 8 and the auxiliary air pipe 9 is discharged through the air outlet pipe head 7 to act on the refrigerator door, because the air outlet pipe head 7 discharges soft air in the early stage, the phenomenon that the uncured refrigerator door is deformed under the action of strong air pressure is avoided, and the soft air discharge can not quickly and effectively blow away substances overflowing from the surface layer in the baking and curing process of the surface layer of the refrigerator door, so that the drying setting time is long under the condition of certain temperature, and the curing of the refrigerator door is ensured to reach a certain degree, the refrigerator door can bear a certain air pressure, so that substances emitted from the surface layer in the drying and curing process of the refrigerator door can be blown away by the boosted air flow, and the curing and baking effect is improved;
when the explosion-proof bidirectional fan 3 blows air to the side where the main air pipe 8 and the auxiliary air pipe 9 are located, the other side of the explosion-proof bidirectional fan generates an air suction effect, so that the auxiliary air pipe 25 sucks air from the trapezoidal groove body in the sealing strip 26 to generate negative pressure, the sealing strip 26 is tightly adsorbed on the furnace body 1, the sealing effect is ensured, heat loss is avoided, meanwhile, the auxiliary air pipe 25 acts on the suction block 28 due to air suction, the suction block is attracted into the butt-joint cylinder 27 to be clamped, and therefore the furnace door 2 is automatically fixed relative to the furnace body 1;
when the door 2 needs to be opened to take out the refrigerator door, the explosion-proof bidirectional fan 3 is operated to rotate reversely, air is sucked from the side where the main air pipe 8 and the auxiliary air pipe 9 are located, at the moment, the movable fan blades 20 in the butt joint sliding pipe 22 rotate and are attached to the limiting convex ring 23 under the air suction effect, the port of the butt joint sliding pipe 22 is sealed, after the port of the butt joint sliding pipe 22 is sealed, the whole butt joint sliding pipe 22 slides into the second splicing pipe head 18 along the strip-shaped sliding groove 19 under the air suction effect to be separated from the first splicing pipe head 15, meanwhile, air is blown from the other side of the explosion-proof bidirectional fan 3 to enter the auxiliary air pipe 25, the negative pressure of the sealing strip 26 is convenient to relieve, the suction block 28 resets under the resilience force of the connecting spring 30, the door 2 is convenient to open, the fan cover 4 and the explosion-proof bidirectional fan 3 rotate together with the door 2 to take out from the interior of the furnace body 1, and then the refrigerator door is taken out, dried and cured.
Although one embodiment of the present invention has been described in detail, the description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
