Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, and specifically to an aluminum alloy surface spraying machine. Background Technology

[0002] Aluminum alloys are lightweight metallic materials made with aluminum as the base material and alloying elements such as copper, magnesium, silicon, zinc, and manganese added. They possess low density, high strength, and excellent machinability. To provide corrosion protection and insulation, aluminum alloys typically undergo a spray coating process.

[0003] During spray painting, paint is typically applied evenly to the surface of aluminum alloy using a spray painting machine. However, in winter, the low ambient temperature increases the viscosity of the paint, reducing its fluidity. This poor flowability makes it difficult for the paint to be dispensed from the spray painting machine, thus affecting the aluminum alloy spraying process. Therefore, how to effectively heat the paint in winter is a crucial issue that needs to be addressed in the design of aluminum alloy surface spray painting machines. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an aluminum alloy surface spraying machine.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An aluminum alloy surface spraying machine includes an aluminum alloy spraying shell and a drying shell, the aluminum alloy spraying shell and the drying shell are fixedly connected to each other, four support feet are fixedly connected to the bottom side wall of the aluminum alloy spraying shell and the drying shell, and a transmission belt is fixedly installed inside the aluminum alloy spraying shell and the drying shell.

[0008] A heating structure is provided on the spraying structure, and the heating structure heats the interior of the spraying structure.

[0009] A drying structure is disposed within a drying shell;

[0010] Preferably, a material passage groove is provided on the side wall of the aluminum alloy spray coating shell and the drying shell.

[0011] In this technical solution, the feed chute facilitates the feeding and unloading of aluminum alloy.

[0012] Preferably, a support plate is fixedly connected to the inner wall of the aluminum alloy spray-coated shell.

[0013] In this technical solution, the support plate supports the spray head.

[0014] Preferably, the spraying structure includes an outer shell, an inner shell, a feed pipe, a paint pump, a feed box, feed branch pipes, and a spray head. The outer shell is fixedly connected to the top side wall of the aluminum alloy spraying housing, the inner shell is fixedly connected to the inner side wall of the outer shell, the feed pipe is fixedly connected to the bottom side walls of the outer shell and the inner shell, the bottom of the feed pipe is fixedly connected to the input end of the paint pump, the paint pump is fixedly connected to the top inner side wall of the aluminum alloy spraying housing, the output end of the paint pump is fixedly connected to the feed box, the feed box is fixedly connected to the top side wall of the support plate, feed branch pipes are fixedly connected at equal intervals on the side wall where the feed box is connected to the support plate, and the bottom of the feed branch pipe is fixedly connected to the spray head.

[0015] In this technical solution, the paint pump draws paint through the feed pipe, and then feeds it into the spray head through the feed box and feed branch pipe. The spray head then sprays the paint onto the surface of the aluminum alloy.

[0016] Preferably, the bottom inner wall of the inner shell is inclined toward the feed pipe.

[0017] In this technical solution, the paint on the inner shell is facilitated to flow towards the feed pipe for feeding.

[0018] Preferably, a feed funnel is fixedly connected to the top sidewall of the outer shell and the inner shell, and a temperature sensor is fixedly connected to the top inner sidewall of the inner shell.

[0019] In this technical solution, paint is poured into the inner shell through a feeding funnel, and a temperature sensor monitors the temperature inside the inner shell.

[0020] Preferably, the heating structure includes a vent pipe, an insulation layer, a ventilation duct, and an exhaust fan. The vent pipe is coiled in the cavity between the outer shell and the inner shell. One end of the vent pipe is fixedly connected to the front side wall of the drying shell, and the other end of the vent pipe is fixedly connected to the top side wall of the drying shell. The other end of the vent pipe is fixedly connected to the ventilation duct. An exhaust fan is fixedly installed on the inner side wall of the ventilation duct. The insulation layer is fixedly connected to the side wall of the vent pipe, and the insulation layer is located on the outer side of the outer shell.

[0021] In this technical solution, the exhaust fan draws air, causing the end of the vent pipe located at the bottom of the electric heating grid to draw in hot air. After the vent pipe draws in hot air, the hot air flows along the coiled vent pipe. The inner shell and the vent pipe are made of materials with good thermal conductivity, so that the hot air exchanges heat with the paint in the inner shell through the vent pipe and the side wall of the inner shell, thereby heating the paint. The hot air is used to dry and heat the paint in the inner shell.

[0022] Preferably, the stirring structure includes a motor, a rotating rod, a stirring rod, and a scraper. The rotating rod is rotatably connected to the top side wall of the outer shell and the inner shell. The motor is fixedly connected to the top side wall of the outer shell. The rotating end of the motor is fixedly connected to the top end of the rotating rod. The stirring rod is fixedly connected at equal intervals to the side walls on both sides of the rotating rod. The other end of the stirring rod is fixedly connected to the scraper.

[0023] In this technical solution, the motor rotates, which drives the rotating rod to rotate. The rotating rod drives the stirring rod to rotate, which in turn drives the scraper to rotate. The rotation of the stirring rod stirs the paint.

[0024] Preferably, the scraper is attached to the inner wall of the inner shell.

[0025] In this technical solution, the rotating scraper scrapes and cleans the inner wall of the inner shell, preventing some paint from adhering to the inner wall of the inner shell and making it difficult to unload the material.

[0026] Preferably, the drying structure includes a second ventilation duct, a dustproof net, a second exhaust fan, and an electric heating net. The second ventilation duct is fixedly connected to the top side wall of the drying shell, the second exhaust fan and two dustproof nets are fixedly connected to the inner side wall of the ventilation duct, and the electric heating net is fixedly connected to the inner side wall of the drying shell.

[0027] In this technical solution, an electric heating mesh is used for heating, and an exhaust fan is used for ventilation, blowing air out towards the electric heating mesh. The dustproof mesh can prevent external impurities and dust from being drawn into the drying shell. When the air passes through the electric heating mesh, the electric heating mesh heats it up to form hot air. The hot air is blown onto the painted aluminum alloy surface to dry the paint on the aluminum alloy surface and accelerate the drying of the paint on the aluminum alloy surface.

[0028] The beneficial effects of this utility model are:

[0029] 1. Paint is drawn through a paint pump and fed into the spray head via a feed pipe, then fed into the spray box and feed branch pipe. The spray head sprays the paint onto the surface of the aluminum alloy. After being painted, the aluminum alloy moves into the drying chamber, where an electric heating grid heats it, and an exhaust fan blows air through it. As the air passes through the electric heating grid, it is heated to create hot air. This hot air then dries the paint on the painted aluminum alloy surface, facilitating better painting and faster drying of the paint.

[0030] 2. The exhaust fan draws in hot air, which then flows along the coiled exhaust pipe. The hot air exchanges heat with the paint in the inner shell through the exhaust pipe and the side wall of the inner shell, thus heating the paint. This facilitates better heating of the paint in the inner shell and prevents the paint from becoming less fluid and difficult to dispense when the temperature is low in winter.

The aluminum alloy spraying shell 1 and the drying shell 2 are fixedly connected to each other. Four support feet 3 are fixedly connected to the bottom side walls of the aluminum alloy spraying shell 1 and the drying shell 2. A transmission belt is fixedly installed inside the aluminum alloy spraying shell 1 and the drying shell 2.

[0041] A stirring structure 6 is disposed inside the spraying structure 5;

[0042] Heating structure 8 is disposed on spraying structure 5, and heating structure 8 heats the interior of spraying structure 5;

[0043] Drying structure 9 is disposed inside the drying shell 2;

[0044] Material passage troughs 11 are provided on the side walls of the aluminum alloy spray-coated housing 1 and the drying housing 2.

[0045] The feed chute 11 facilitates the feeding and unloading of aluminum alloy.

[0046] A support plate 12 is fixedly connected to the inner wall of the aluminum alloy spray-coated housing 1.

[0047] The support plate 12 supports the spray head 507.

[0048] The spraying structure 5 includes an outer shell 501, an inner shell 502, a feed pipe 503, a paint pump 504, a feed box 505, feed branch pipes 506, and a spray head 507. The outer shell 501 is fixedly connected to the top side wall of the aluminum alloy spraying housing 1. The inner shell 502 is fixedly connected to the inner side wall of the outer shell 501. The feed pipe 503 is fixedly connected to the bottom side walls of the outer shell 501 and the inner shell 502. The bottom of the feed pipe 503 is fixedly connected to the input end of the paint pump 504. The paint pump 504 is fixedly connected to the top inner side wall of the aluminum alloy spraying housing 1. The output end of the paint pump 504 is fixedly connected to the feed box 505. The feed box 505 is fixedly connected to the top side wall of the support plate 12. Feed branch pipes 506 are fixedly connected at equal intervals on the side wall of the feed box 505 connected to the support plate 12. The bottom of the feed branch pipes 506 is fixedly connected to the spray head 507.

[0049] Paint pump 504 draws paint through feed pipe 503, and then feeds it into spray head 507 through feed box 505 and feed branch pipe 506. Spray head 507 sprays paint onto the surface of aluminum alloy.

[0050] The bottom inner wall of the inner shell 502 is inclined toward the feed pipe 503.

[0051] This facilitates the flow of paint from the inner shell 502 towards the feed pipe 503 for feeding.

[0052] A feeding funnel 7 is fixedly connected to the top side wall of the outer shell 501 and the inner shell 502, and a temperature sensor 10 is fixedly connected to the top inner side wall of the inner shell 502.

[0053] Paint is poured into the inner shell 502 through the feed funnel 7, and the temperature sensor 10 monitors the temperature in the inner shell 502.

[0054] The heating structure 8 includes a vent pipe 801, a heat insulation layer 8022, a ventilation duct 803, and an exhaust fan 804. The vent pipe 801 is coiled in the cavity between the outer shell 501 and the inner shell 502. One end of the vent pipe 801 is fixedly connected to the front side wall of the drying shell 2, and the other end of the vent pipe 801 is fixedly connected to the top side wall of the drying shell 2. The other end of the vent pipe 801 is fixedly connected to the ventilation duct 803. An exhaust fan 804 is fixedly installed on the inner side wall of the ventilation duct. The heat insulation layer 8022 is fixedly connected to the side wall of the vent pipe 801, and the heat insulation layer 8022 is located on the outside of the outer shell 501.

[0055] The exhaust fan 804 draws air, causing the end of the vent pipe 801 located at the bottom of the electric heating grid 904 to draw in hot air. After the vent pipe 801 draws in hot air, the hot air flows along the coiled vent pipe 801. The inner shell 502 and the vent pipe 801 are made of materials with good thermal conductivity, so that the hot air exchanges heat with the paint in the inner shell 502 through the side wall of the vent pipe 801 and the inner shell 502, thereby heating the paint. The hot air is used to dry and heat the paint in the inner shell 502 effectively.

[0056] The stirring structure 6 includes a motor 601, a rotating rod 602, a stirring rod 603, and a scraper 604. The rotating rod 602 is rotatably connected to the top side wall of the outer shell 501 and the inner shell 502. The motor 601 is fixedly connected to the top side wall of the outer shell 501. The rotating end of the motor 601 is fixedly connected to the top end of the rotating rod 602. The stirring rod 603 is fixedly connected at equal intervals to the side walls on both sides of the rotating rod 602. The other end of the stirring rod 603 is fixedly connected to the scraper 604.

[0057] The rotation of motor 601 drives the rotation rod 602 to rotate, which in turn drives the stirring rod 603 to rotate. The stirring rod 603 then drives the scraper frame 604 to rotate, and the rotation of the stirring rod 603 stirs the paint.

[0058] The scraper 604 is attached to the inner wall of the inner shell 502.

[0059] The scraper 604 rotates to scrape and clean the inner wall of the inner shell 502, preventing some paint from adhering to the inner wall of the inner shell 502 and making it difficult to unload the material.

[0060] The drying structure 9 includes a second ventilation duct 901, a dustproof net 902, a second exhaust fan 903, and an electric heating net 904. The second ventilation duct 901 is fixedly connected to the top side wall of the drying shell 2. The second exhaust fan 903 and two dustproof nets 902 are fixedly connected to the inner side wall of the ventilation duct. The electric heating net 904 is fixedly connected to the inner side wall of the drying shell 2.

[0061] The electric heating mesh 904 heats the surface, while the exhaust fan 903 draws air out, directing the air towards the electric heating mesh 904. The dustproof mesh 902 prevents external impurities and dust from being drawn into the drying housing 2. As the air passes through the electric heating mesh 904, it heats the surface to generate hot air. This hot air is then blown onto the painted aluminum alloy surface to dry the paint and accelerate the drying process.

[0062] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The aluminum alloy to be sprayed is placed on the conveyor belt 4, which moves the aluminum alloy to the right. Paint is poured into the inner shell 502 through the feed funnel 7. The motor 601 rotates, which drives the rotating rod 602 to rotate. The rotating rod 602 drives the stirring rod 603 to rotate. The stirring rod 603 drives the scraper 604 to rotate. The stirring rod 603 stirs the paint, and the scraper 604 scrapes and cleans the inner wall of the inner shell 502 to prevent some paint from adhering to the inner wall of the inner shell 502 and making it difficult to feed the material.

[0063] When the aluminum alloy moves below the spray head 507, the paint pump 504 draws paint through the feed pipe 503 and then feeds it into the spray head 507 through the feed box 505 and the feed branch pipe 506. The spray head 507 sprays the paint onto the surface of the aluminum alloy. After being painted, the aluminum alloy continues to move with the conveyor belt. After moving into the drying shell 2, the electric heating mesh 904 heats it, and the exhaust fan 903 blows the air out of the electric heating mesh 904. The dustproof mesh 902 can prevent external impurities and dust from being drawn into the drying shell 2. When the air passes through the electric heating mesh 904, the electric heating mesh 904 heats it to form hot air. The hot air blows onto the surface of the painted aluminum alloy to dry the paint on the surface of the aluminum alloy and accelerate the drying of the paint on the surface of the aluminum alloy.

[0064] When the temperature is low in winter, the temperature sensor 10 detects the temperature in the inner shell 502. When the temperature is low, the exhaust fan 804 draws air in, causing the end of the vent pipe 801 located at the bottom of the electric heating grid 904 to be drawn in. After the vent pipe 801 draws in hot air, the hot air flows along the coiled vent pipe 801. The inner shell 502 and the vent pipe 801 are made of materials with good thermal conductivity, so that the hot air exchanges heat with the paint in the inner shell 502 through the side wall of the vent pipe 801 and the inner shell 502, thereby heating the paint. It is better to use the drying hot air to heat the paint in the inner shell 502, so as to avoid the paint flow being poor and difficult to feed when the temperature is low in winter. After heat exchange, the air is drawn back into the drying shell 2 by the exhaust fan 804.
