An air pump can be used to blow in cold air, and the cold air can cool the surrounding air when flowing inside the first wind tube shell, and then preliminarily cool the aluminum profile to avoid cracking and deformation caused by excessive temperature difference when the aluminum profile enters the oil cooling.

[0014] The effect achieved by the above components is: when oil cooling is not needed, the discharge rack can be lifted upwards by the telescopic member (which can be an electric telescopic rod), so that the roller in the oil cooling frame can be placed at the bottom of the aluminum profile to support the aluminum profile, thereby facilitating the transportation of the aluminum profile.

When the cold air flows inside the first air cylinder shell, it can cool down the surrounding air, and then preliminarily cool down the aluminum profile, avoiding the aluminum profile from being instantly cooled down and causing cracking and deformation due to excessive temperature difference when entering the oil cooler. When the spiral fan blades follow the rotation of the air cylinder wheel, they push the external air away along the inner cavity of the air cylinder wheel, thereby improving the air flow on the surface of the aluminum profile to preliminarily cool the aluminum profile.

[0025] Example 1, as Figure 1-3As shown, a discharging cooling device for an aluminum rod extruder 2 includes a cooling member 7, which is installed at the discharging port of the extruder 2. The cooling member 7 includes a first wind cylinder shell 71, wherein the first wind cylinder shell 71 and the extruder 2 are fixed, and the interior of the first wind cylinder shell 71 is rotatably connected to a wind cylinder wheel 74, and the surface of the wind cylinder wheel 74 is evenly and fixedly connected with fan blades 75, wherein the fan blades 75 are located in the gap between the wind cylinder wheel 74 and the first wind cylinder shell 71, and the inner wall of the wind cylinder wheel 74 is fixedly connected with spiral leaves 76. The aluminum rod enters the extruder 2 from the feed port of the extruder 2, is heated, and then is extruded into an aluminum profile from the discharge port mold. The aluminum profile passes through the first wind cylinder shell 71, and the first wind cylinder shell 71 is connected to the output end of the air pump. The aluminum rod is placed on the feed rack 1 and is transmitted through the transmission on the feed rack 1. The structure feeds the aluminum rod into the extruder 2, and uses the control panel 3 to control the high temperature generated inside the extruder 2 to heat the aluminum rod, and then extrude the high-temperature aluminum rod along the discharge template of the extruder 2 (the aluminum rod extruder 2 is an existing conventional equipment, so it will not be described in detail here). Then, air is generated by an external air pump, and the air blows the fan blades 75, and the fan blades 75 drive the wind tube wheel 74 to rotate inside the first wind tube shell 71. The air pump can be used to blow in cold air. When the cold air flows inside the first wind tube shell 71, it can cool the surrounding air, and then preliminarily cool the aluminum profile to avoid the aluminum profile from entering the oil cooling instantaneous temperature difference causing cracking and deformation. When the spiral fan blades 75 rotate with the wind tube wheel 74, the external air is pushed away along the inner cavity of the wind tube wheel 74, thereby improving the aluminum profile. The surface air flow is used to preliminarily cool the aluminum profile. The surface of the first wind cylinder shell 71 is connected with a first air inlet pipe 72 and an air outlet pipe 73, wherein the first air inlet pipe 72 is in an eccentric state. The first air inlet pipe 72 in the eccentric state can push the wind cylinder wheel 74 to rotate. The second wind cylinder shell 77 is installed on the side of the first wind cylinder shell 71. A cavity is set inside the wind cylinder wheel 74. The wind cylinder wheel 74 slides in the second wind cylinder shell 77. The second wind cylinder shell 77 is connected to the output end of the air pump through the second air inlet pipe 78. The surface of the wind cylinder wheel 74 is provided with an air outlet and is connected to the cavity. The air output by the air pump can enter the cavity of the wind cylinder wheel 74 from the second wind cylinder shell 77 and then be blown directly to the surface of the aluminum profile from the air outlet to preliminarily cool the surface of the aluminum profile. A collecting component is provided on the side of the cooling component 7. 6. The collecting component 6 includes an oil cooling frame 61, into which oil is introduced by a circulating pump. The oil cooling frame 61 is located on one side of the cooling component 7 and is lower than the other side. The circulating oil pump draws the cooling oil into the oil cooling frame 61. The aluminum profile is oil-cooled on the surface of the oil cooling frame 61. The cooling oil flows into the collecting frame 66 and is then drawn into the oil cooling frame 61 by the circulating oil pump for recycling. A discharge rack 4 is fixedly installed below the oil cooling frame 61. A telescopic member 5 is fixedly connected below the discharge rack 4. When oil cooling is not required, the discharge rack 4 can be lifted upward by the telescopic member 5 (which can be an electric telescopic rod), so that the roller 62 in the oil cooling frame 61 is cushioned at the bottom of the aluminum profile to support the aluminum profile, thereby facilitating the transportation of the aluminum profile. A mounting frame 63 is fixedly connected above the discharge rack 4.An oil spray ring 64 is fixedly connected to the upper end of the mounting frame 63. The upper end of the oil spray ring 64 is connected to an oil guide pipe 65. This oil guide pipe 65 is connected to a collection frame 66 via a circulation pump. The collection frame 66 is located below the oil cooling frame 61. The aluminum profile passes through the oil spray ring 64. The circulation pump can also evenly spray oil from the inner cavity of the oil spray ring 64 onto the aluminum profile, cooling the aluminum profile. A guide cone 67 is fixedly connected to the lower part of the oil cooling frame 61. The guide cone 67 is located above the collection frame 66 and serves to guide the oil into the collection frame 66.

[0026] Working principle: Place the aluminum rod on the feed rack 1, and feed the aluminum rod into the extruder 2 through the transmission structure on the feed rack 1. Use the control panel 3 to control the high temperature generated inside the extruder 2 to heat the aluminum rod, and then extrude the high-temperature aluminum rod along the discharge template of the extruder 2 (the aluminum rod extruder 2 is an existing conventional equipment, so it will not be described in detail here). Then, an external air pump is used to generate air, and the air blows the fan blades 75. The fan blades 75 drive the wind cylinder wheel 74 to rotate inside the first wind cylinder shell 71. An air pump can be used to blow in cold air. When the cold air flows inside the first wind cylinder shell 71, it can cool the surrounding air, and then preliminarily cool the aluminum profile to avoid cracking and deformation caused by excessive temperature difference when the aluminum profile enters the oil cooling. When the spiral fan blades 75 rotate with the wind cylinder wheel 74, the external air is pushed away along the inner cavity of the wind cylinder wheel 74, thereby improving the aluminum profile. The air flows on the surface of the profile to perform preliminary cooling of the aluminum profile. The first air inlet pipe 72 is in an eccentric state to drive the wind cylinder wheel 74 to rotate. The air output by the air pump can enter the cavity of the wind cylinder wheel 74 from the second wind cylinder shell 77 and then be blown directly to the surface of the aluminum profile from the air outlet to perform preliminary cooling of the surface of the aluminum profile. The circulating oil pump draws the cooling oil into the oil cooling frame 61. The aluminum profile is oil-cooled on the surface of the oil cooling frame 61. The cooling oil flows into the collecting frame 66 and is then drawn into the oil cooling frame 61 by the circulating oil pump for recycling. When oil cooling is not needed, the discharging rack 4 can be lifted upward by the telescopic member 5 (which can be an electric telescopic rod), so that the roller 62 in the oil cooling frame 61 is cushioned at the bottom of the aluminum profile to support the aluminum profile, thereby facilitating the transportation of the aluminum profile. The circulating pump can also evenly spray oil from the inner cavity of the oil spray ring 64 to the aluminum profile to cool the aluminum profile.
