[0019] As Figure 1 , Figure 2 , Figure 3The utility model discloses an embodiment provides a kind of aging furnace for aluminium profile, comprising: furnace body 1, hot air machine 2, first baffle 3, second baffle 4, third baffle 5, furnace body 1 both sides are equipped with opening, and opening is equipped with furnace door 6, furnace door 6 is connected with furnace body 1 by hinge;First guide rail 7 and second guide rail 8 are equipped on the inner wall of furnace body 1 middle part, first guide rail 7 and second guide rail 8 are parallel to each other, and first guide rail 7 and second guide rail 8 are perpendicular to furnace body 1 bottom surface;First baffle 3 is slidably installed on first guide rail 7, second baffle 4 is slidably installed on second guide rail 8, third baffle 5 is fixedly installed on one side of second guide rail 8 upper portion, and hot air machine 2 is installed on furnace body 1 upper portion, and hot air machine 2 is communicated with furnace body 1 inner chamber.

[0020] When aluminium profile is handled, after opening furnace door 6, push the trolley loaded with aluminium profile into furnace body 1, then close furnace door 6, make furnace body 1 form a closed space, hot air machine 2 uses existing technology, heats air by electric heating or gas mode, then makes air flow circulation under the action of fan, realizes the purpose of heating in furnace body 1, furnace body 1 is heated under the action of hot air machine 2, thereby heats the aluminium profile in furnace body 1, makes it keep in certain temperature, improves the hardness of aluminium profile, and eliminates internal stress, after heat treatment is completed, aluminium profile needs to be pulled out, when discharging, first baffle 3 is lowered by winch 14, when first baffle 3 descends, second protruding portion 10 supports third protruding portion 11 lower part, so that second baffle 4 and first baffle 3 descend synchronously, let fourth protruding portion 12 and fifth protruding portion 13 contact, second baffle 4 stops sliding down, at this moment, first baffle 3 continues to slide down, until second baffle 4 descends to furnace body 1 bottom, thereby closes the middle part of furnace body 1, after opening the furnace door 6 of discharging side, the trolley loaded with aluminium profile is pulled out by discharging mechanism, then new untreated aluminium profile is put in, and the next batch of aluminium profile is handled, when discharging, because there is the obstruction of first baffle 3, second baffle 4 and third baffle 5, the hot air flow in the other side of furnace body 1 can be prevented from losing, thereby reducing the heat loss when feeding and discharging, new material needs to be heated for a period of time by hot air machine 2 due to lower temperature, after the temperature of both sides of furnace body 1 approaches, first baffle 3 is raised by winch 14, after second protruding portion 10 and third protruding portion 11 contact when first baffle 3 rises, first baffle 3 drives second baffle 4 to rise together, thereby opening the middle part, so that the air flow in furnace body 1 can flow freely, make the temperature distribution in furnace body 1 uniform. So alternating feeding and discharging aluminium profile, realize the heat treatment of aluminium profile.

[0021] When the length of single aluminium profile exceeds half of the length of furnace body 1, first baffle 3 and second baffle 4 can be raised, so that the whole furnace body 1 can be used for heat treatment of super-long aluminium profile, improve the application scene of furnace body.

[0022] Preferably, as Figure 2 ,Figure 3 As shown, the first partition 3 has a first protrusion 9 and a second protrusion 10 at its upper and lower ends, respectively, and the second partition 4 has a third protrusion 11 at its lower end. The first protrusion 9 and the second protrusion 10 are both located on the side of the first partition 3 facing the second partition 4, and the third protrusion 11 is located between the first protrusion 9 and the second protrusion 10. The first protrusion 9 and the second protrusion 10 are used to limit the third protrusion 11. When the first partition 3 rises and falls, the second protrusion 10 can drive the third protrusion 11 to achieve synchronous movement of the first partition 3 and the second partition 4. When the first partition 3 descends to its lowest point, the first protrusion 9 contacts the third protrusion 11, thereby sealing the gap between the first partition 3 and the second partition 4 through the first protrusion 9 and the third protrusion 11, preventing airflow from passing through the gap and reducing heat loss.

[0023] In a specific embodiment, such as Figure 2 , Figure 3 As shown, the upper end of the second partition 4 is provided with a fourth protrusion 12 facing the third partition 5, and the lower end of the third partition 5 is provided with a fifth protrusion 13 facing the second partition 4. The fifth protrusion 13 is used to limit the fourth protrusion 12. When the second partition 4 descends, the fourth protrusion 12 contacts the fifth protrusion 13, thereby limiting the second partition 4 and blocking it at the height position in the middle of the furnace body 1. This allows the first partition 3, the second partition 4, and the third partition 5 to block the middle of the furnace body 1, reducing the loss of hot airflow during material discharge.

[0024] Specifically, a winch 14 is provided on the upper part of the furnace body 1, and a steel cable 15 is provided on the winch 14. The steel cable 15 passes through the furnace body 1 and is connected to the first partition 3. The winch 14 can pull the steel cable 15, thereby directly driving the first partition 3 and indirectly driving the second partition 4 to rise and fall, so as to achieve the sealing of the middle part of the furnace body 1.

[0025] Specifically, such as Figure 1 As shown, the hot air blower 2 is equipped with a first air duct 16 and a second air duct 17. The furnace body 1 is provided with air inlets on both sides of the first guide rail 7. The hot air blower 2 is connected in parallel with the air inlets through the second air duct 17. The upper part of both ends of the furnace body 1 is provided with air outlets. The hot air blower 2 is connected in parallel with the air outlets through the first air duct 16. The hot air blower 2 adopts existing technology to heat the air by electric heating or gas heating. Then, the airflow is driven by the blower to enter the first air duct 16 from the air outlet and flow into the hot air blower 2. After being heated, it flows back into the furnace body 1 from the second air duct 17 through the air inlet, realizing the circulation heating of the air.

[0026] In a preferred embodiment, the first air pipe 16 and each air outlet and the second air pipe 17 and each air inlet are provided with a valve 18, and during discharging, the air inlet and outlet on the discharging side can be closed through the valve 18, so as to avoid heat loss and improve energy utilization.

[0027] Of course, the present application can also have other various embodiments, and based on the present embodiment, other embodiments obtained by those skilled in the art without any creative labor shall fall within the protection scope of the present application.
