[0021] Compared with the prior art, the present invention provides an aluminum profile manufacturing device having the following

[0022] Beneficial effects:

The aluminum profile manufacturing device drives the driven gear to rotate through the inert gear, so that the triangular block moves up and down in the hot melt tank in different directions, so that the triangular block can better break up the waste aluminum, thereby making the waste aluminum more efficiently heated and discharge impurities.

[0026] 4. The aluminum profile manufacturing device opens the valve in the delivery pipe, and the coolant in the first heat pipe, the second heat pipe and the third heat pipe will circulate. When the coolant passes through the third heat pipe, the third heat pipe will transfer the heat to the waste aluminum material in the flat material pipe through the thin plate. The waste aluminum material will be heated, and the coolant can be cooled, so the temperature of the upper mold and the lower mold is effectively utilized, and the waste of heat is reduced.

[0050] Embodiment three:

[0051] Reference Figure 1-Figure 3 as well as Figure 6 , which is basically the same as the second embodiment, and further discloses a specific implementation scheme of the driving unit.

[0052] The driving unit comprises a bracket 9 fixedly connected to the hot melt tank 2, on which a driving motor 13 is fixedly mounted, wherein a driving shaft 10 is fixedly connected to the turntable 8, and the driving shaft 10 is connected to the output shaft of the driving motor 13 via two meshing transmission gears 14.

[0053] Specifically, when the hot melt tank 2 is used to melt the scrap aluminum, the drive motor 13 is started. The drive motor 13 drives the drive shaft 10 to rotate through two mutually meshing transmission gears 14. The drive shaft 10 drives the turntable 8 to rotate. The turntable 8 drives the vertical rod 11 and the triangular block 12 to stir the scrap aluminum in the hot melt tank 2, so that the scrap aluminum can be heated more and more fully, which is also convenient for the discharge of impurities in the scrap aluminum, and indirectly improves the quality of subsequent aluminum profiles.

[0054] A ring gear 17 is fixedly mounted on the above-mentioned bracket 9, a driven gear 16 is fixedly mounted on the vertical rod 11, a lifting portion is connected between the driven gear 16 and the ring gear 17, and the lifting portion is used to drive the driven gear 16 to lift and rotate; the lifting portion includes a reciprocating screw 15 rotatably connected to the turntable 8, an idle gear is fixedly mounted on the reciprocating screw 15, and the idle gear is not numbered in the figure, wherein the idle gear is meshed and connected with the driven gear 16 and the ring gear 17, the outer wall of the reciprocating screw 15 is threadedly connected with a lifting plate 18, and the upper end of the vertical rod 11 is rotatably connected to the lifting plate 18.

[0055] Specifically, during the rotation of the turntable 8, the vertical rod 11 will revolve around the axis of the turntable 8, and drive the driven gear 16 and the idle gear to revolve synchronously. The idle gear will drive the reciprocating screw 15 to rotate under the action of the ring gear 17. The reciprocating screw 15 will drive the vertical rod 11 to move back and forth up and down through the lifting plate 18. The lifting plate 18 will drive the triangular block 12 to move up and down in the hot melt tank 2. When the triangular block 12 is lifted upward, since its inclined surface is set downward, its right-angled side can lift the scrap aluminum at the bottom of the hot melt tank 2 upward. When the triangular block 12 moves downward, it will be inserted into the inner bottom of the hot melt tank 2 under the guidance of its inclined surface. Therefore, the triangular block 12 that reciprocates up and down can lift the scrap aluminum at the bottom of the hot melt tank 2 upward, so as to improve the heating uniformity and hot melting efficiency of the scrap aluminum.

[0056] Specifically, during the rotation of the reciprocating screw 15, the reciprocating screw 15 will also drive the driven gear 16 to rotate through the inert gear, and the driven gear 16 will drive the vertical rod 11 to rotate, and the vertical rod 11 will drive the triangular block 12 to revolve around the vertical rod 11, so that the triangular block 12 moves up and down in the hot melt tank 2 in different directions, so that the triangular block 12 can better break up the scrap aluminum, thereby allowing the scrap aluminum to be heated more efficiently and impurities to be discharged.

[0057] Embodiment 4:

[0058] Reference Figure 1-Figure 4 as well as Figure 7 , which is basically the same as the third embodiment, and further discloses a specific implementation plan for facilitating the hot melt tank 2 to complete the loading.

[0059] A loading hopper 19 is fixedly installed on the frame 1, and a flat material tube 20 facing the loading port 4 is fixedly installed at the lower end of the loading hopper 19, and a valve is installed in the flat material tube 20, wherein a thin plate 21 is longitudinally slidably installed in the flat material tube 20, and a dredging part for driving the thin plate 21 to move up and down is provided on the turntable 8; the dredging part includes a fixed plate 23 fixedly connected to the outer wall of the flat material tube 20, and a T-shaped plate 22 is fixedly connected to the lower end of the thin plate 21, and a spring 24 is installed between the T-shaped plate 22 and the fixed plate 23. When the lifting plate 18 rotates with the turntable 8, multiple lifting plates 18 will lift the T-shaped plate 22 in sequence.

[0060] Specifically, when in use, the crushed scrap aluminum is placed in the loading hopper 19, and then the valves in the flat material tube 20 and the loading port 4 are opened, so that the scrap aluminum in the loading hopper 19 enters the hot melt tank 2 through the flat material tube 20 and the loading port 4, so that the loading work can be completed. During the rotation of the turntable 8, the turntable 8 will drive the lifting plate 18 to revolve around its axis. When the lifting plate 18 moves to the bottom of the T-shaped plate 22, the lifting plate 18 will lift the T-shaped plate 22 upward. When the lifting plate 18 is away from the bottom of the T-shaped plate 22, the spring 24 will drive the T-shaped plate 22 to slide downward and reset. Therefore, when multiple lifting plates 18 pass through the lower end of the T-shaped plate 22 in turn, the T-shaped plate 22 will shake back and forth up and down, thereby driving the thin plate 21 to shake up and down in the flat material tube 20, thereby preventing blockage in the flat material tube 20.

[0061] Embodiment five:

[0062] Reference Figure 1-Figure 5 as well as Figure 8 , which is basically the same as the fourth embodiment, and further discloses a specific implementation scheme for heat dissipation of the lower mold 5 and the upper mold 7.

[0063] The first heat pipe 25 and the second heat pipe 27 are fixedly installed in the above-mentioned lower mold 5 and the upper mold 7 respectively, and the third heat pipe 28 is fixedly installed in the thin plate 21, wherein the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 are connected in series through the first long tube 26, the second long tube 29 and the third long tube 30 in turn, and a closed loop is formed between the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28, and the interior is filled with coolant. The third long tube 30 is rotatably connected with a rotating tube 31, and the rotating tube 31 is fixedly installed with a first fan blade, which is not shown in the figure. Its function is to replace the circulating pump. The hot melt tank 2 is provided with a circulation part for driving the rotating tube 31 to rotate.

[0064] Specifically, when the lower mold 5 and the upper mold 7 need to be cooled, the rotating tube 31 is driven to rotate through the circulation part, and the rotating tube 31 will drive the first fan blade inside it to rotate. The rotating first fan blade will cause the coolant in the third long tube 30 to flow continuously, and under the action of the first long tube 26 and the second long tube 29, the coolant in the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 will circulate. When the coolant enters the first heat pipe 25 and the second heat pipe 27, the coolant will absorb the temperature on the lower mold 5 and the upper mold 7, thereby completing the cooling of the upper mold 7 and the lower mold 5. When the coolant passes through the third heat pipe 28, the third heat pipe 28 will transfer the heat to the waste aluminum material in the flat material tube 20 through the thin plate 21, the waste aluminum material will be heated, and the coolant can be dissipated, so that the temperature on the upper mold 7 and the lower mold 5 is effectively utilized, and the waste of heat is reduced. Due to the high thermal conductivity of aluminum, the heat dissipation efficiency of the lower mold 5 and the upper mold 7 can be effectively guaranteed.

[0065] The above-mentioned circulation part includes a vertical pipe 32 rotatably connected to the outer wall of the hot melt tank 2, and a second fan blade is fixedly installed on the inner wall of the vertical pipe 32, and the second fan blade is not shown in the figure, wherein the vertical pipe 32 is connected to the rotating pipe 31 by a chain drive 33, and the upper end of the vertical pipe 32 is fixedly connected to the blowing pipe 34, and the hot melt tank 2 is provided with an air supply part for blowing air to the blowing pipe 34; the air supply part includes a gas storage tank 35 fixedly installed on the hot melt tank 2, and the gas storage tank 35 is used to store high-pressure gas. The input end of the gas storage tank 35 is fixedly connected to the inflation pipe 36 extending into the hot melt tank 2, and the output end of the gas storage tank 35 is fixedly connected to the inflation pipe 36 through the delivery pipe 37, and both the inflation pipe 36 and the delivery pipe 37 are fixedly installed with a one-way valve, and a valve is installed in the delivery pipe 37.

[0066] Specifically, during the heating process of the hot melt tank 2, the valve in the feed port 4 is closed. Since the scrap aluminum contains impurities, the heated scrap aluminum will generate waste gas, and the waste gas will be transported to the gas storage tank 35 through the inflation pipe 36. When the lower mold 5 and the upper mold 7 need to be cooled, the valve in the delivery pipe 37 is opened to allow the gas stored in the gas storage tank 35 to be transported to the blowing pipe 34 through the delivery pipe 37. The blowing pipe 34 will blow air to the vertical pipe 32. Since the second fan blade is installed in the vertical pipe 32, the vertical pipe 32 will drive the rotating pipe 31 to rotate through the chain drive 33, and the rotating pipe 31 will drive the first fan blade inside it to rotate. The rotating first fan blade will cause the coolant in the third long tube 30 to flow continuously, so as to complete the heat dissipation of the mold.

[0067] When the aluminum profile manufacturing device is in use, the crushed scrap aluminum is placed into the loading hopper 19, and then the valves in the flat material tube 20 and the loading port 4 are opened, so that the scrap aluminum in the loading hopper 19 enters the hot melt tank 2 through the flat material tube 20 and the loading port 4, and then the scrap aluminum is heated by the hot melt tank 2 to melt it. During this period, the driving motor 13 is started, and the driving motor 13 drives the driving shaft 10 to rotate through two mutually meshing transmission gears 14, and the driving shaft 10 drives the turntable 8 to rotate, and the turntable 8 drives the vertical rod 11 and the triangular block 12 to stir the scrap aluminum in the hot melt tank 2, so that the scrap aluminum can be heated more and more fully, and it is also convenient to discharge impurities in the scrap aluminum, thereby indirectly improving the quality of subsequent aluminum profiles.

[0068] During the rotation of the turntable 8, the vertical rod 11 will revolve around the axis of the turntable 8, and drive the driven gear 16 and the idle gear to revolve synchronously. The idle gear will drive the reciprocating screw 15 to rotate under the action of the ring gear 17. The reciprocating screw 15 will drive the vertical rod 11 to move back and forth up and down through the lifting plate 18. The lifting plate 18 will drive the triangular block 12 to move up and down in the hot melt tank 2. When the triangular block 12 is lifted upward, since its inclined surface is set downward, its right-angled side can lift the scrap aluminum at the bottom of the hot melt tank 2 upward. When the triangular block 12 moves downward, it will be inserted into the inner bottom of the hot melt tank 2 under the guidance of its inclined surface. Therefore, the triangular block 12 that reciprocates up and down can lift the scrap aluminum at the bottom of the hot melt tank 2 upward, so as to improve the heating uniformity and hot melting efficiency of the scrap aluminum.

[0069] During the rotation of the reciprocating screw 15, the reciprocating screw 15 will also drive the driven gear 16 to rotate through the inert gear, and the driven gear 16 will drive the vertical rod 11 to rotate, and the vertical rod 11 will drive the triangular block 12 to revolve around the vertical rod 11, so that the triangular block 12 moves up and down in the hot melt tank 2 in different directions, so that the triangular block 12 can better break up the scrap aluminum, thereby allowing the scrap aluminum to be heated more efficiently and impurities to be discharged.

[0070] When the scrap aluminum is melted, the valve in the discharge pipe 3 is opened, and the aluminum liquid will flow from the upper mold 7 into the lower mold 5. After the aluminum liquid cools and solidifies, the upper mold 7 is lifted upward and away from the lower mold 5 by the lifting device 6, and the aluminum profile after cooling and solidification is taken out from the lower mold 5.

[0071] During the heating process of the hot melt tank 2, the valve in the feed port 4 is closed. Since the scrap aluminum contains impurities, the heated scrap aluminum will generate waste gas, and the waste gas will be transported to the gas storage tank 35 through the inflation pipe 36. When the lower mold 5 and the upper mold 7 need to be cooled, the valve in the delivery pipe 37 is opened to allow the gas stored in the gas storage tank 35 to be transported to the blowing pipe 34 through the delivery pipe 37. The blowing pipe 34 will blow air to the vertical pipe 32. Since the vertical pipe 32 is equipped with a second fan blade, the vertical pipe 32 will drive the rotating pipe 31 to rotate through the chain drive 33, and the rotating pipe 31 will drive the first fan blade inside it to rotate. The rotating first fan blade will cause the coolant in the third long pipe 30 to flow continuously and cool the coolant in the first long pipe 30. 26 and the second long tube 29, the coolant in the first heat pipe 25, the second heat pipe 27 and the third heat pipe 28 will circulate. When the coolant enters the first heat pipe 25 and the second heat pipe 27, the coolant will absorb the temperature of the lower mold 5 and the upper mold 7, thereby completing the cooling of the upper mold 7 and the lower mold 5. When the coolant passes through the third heat pipe 28, the third heat pipe 28 will transfer the heat to the waste aluminum material in the flat material tube 20 through the thin plate 21. The waste aluminum material will be heated, and the coolant can be cooled, which effectively utilizes the temperature of the upper mold 7 and the lower mold 5 and reduces the waste of heat. Due to the high thermal conductivity of aluminum, the heat dissipation efficiency of the lower mold 5 and the upper mold 7 can be effectively guaranteed.

[0072] During the heat dissipation process of the lower mold 5 and the upper mold 7, in order to improve the heat dissipation efficiency, the valves in the flat material tube 20 and the feeding port 4 are opened to allow the waste aluminum in the feeding hopper 19 to be continuously discharged into the feeding port 4. The flowing waste aluminum can significantly improve the heat dissipation efficiency of the third heat pipe 28, thereby improving the heat dissipation efficiency of the upper mold 7 and the lower mold 5. At the same time, the automatic feeding of the hot melt tank 2 is also completed. Since the waste aluminum is preheated, the heating power of the hot melt tank 2 can be reduced, making it more environmentally friendly to use.

[0073] When the turntable 8 rotates, the turntable 8 will drive the lifting plate 18 to revolve around its axis. When the lifting plate 18 moves to the bottom of the T-shaped plate 22, the lifting plate 18 will lift the T-shaped plate 22 upward. When the lifting plate 18 is away from the bottom of the T-shaped plate 22, the spring 24 will drive the T-shaped plate 22 to slide downward and reset. Therefore, when multiple lifting plates 18 pass the lower end of the T-shaped plate 22 in turn, the T-shaped plate 22 will shake back and forth up and down, thereby driving the thin plate 21 to shake up and down in the flat material tube 20. On the one hand, it can prevent blockage in the flat material tube 20, and on the other hand, it can improve the thermal conductivity of the flat material tube 20.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
