[0002] Drying aluminum alloy paint is a crucial step in surface treatment. Choosing the right drying method directly impacts paint quality and production efficiency. Aluminum alloy paint drying typically involves the curing process following electrostatic spraying, primarily aiming to evaporate solvents in the paint and form a uniform, robust film. According to industry standards, the drying temperature for aluminum alloy paint is generally controlled between 60-80℃. This temperature range ensures sufficient curing of the paint without causing thermal damage to the aluminum alloy substrate.

[0003] In existing aluminum alloy paint drying equipment, in order to facilitate the movement of the aluminum alloy support bracket into the drying equipment for paint drying, channels need to be reserved on both sides of the drying equipment for the support bracket to move. This results in heat flowing out from both sides of the channels during drying, causing heat waste and reducing drying efficiency. Utility Model Content

The support body 2 includes a base plate 21 and a storage rack 22. The aluminum alloy to be dried is placed horizontally on the storage rack 22. Side baffles 23 are provided on both sides of the top of the base plate 21 in the vertical direction. The side baffles 23 are used to prevent heat from being lost from both sides of the drying channel 11.

[0021] The outer casing 1 is an n-shaped cover structure welded from 304 stainless steel; the drying channel 11 is a through cavity with a rectangular cross-section, and the inner wall is covered with a ceramic fiber insulation layer; the mounting cavity 12 is a rectangular groove machined on the front and rear facades of the outer casing 1, with waterproof flanges at the edges; the electric heating mechanism 13 uses a quartz tube heater or a ceramic PTC heating element; the support body 2 is formed by bending Q235 steel; the storage rack 22 is a stepped frame with rollers 24; the side baffle 23 is a galvanized steel plate bending part, and the inner side is covered with a high-temperature resistant silicone sealing strip.

[0022] The heating surface of the electric heating mechanism 13 maintains a 30-50mm air duct gap from the inner wall of the drying channel 11; the side baffle 23 can be connected to the bottom plate 21 by a hinge, and can be rotated outward by 90° for loading and unloading. When closed, it is pressed and sealed by a magnetic buckle.

[0023] By combining the n-shaped outer casing 1 with the adjustable bracket, the dynamic sealing design of the side baffle 23 reduces the heat loss rate and improves the drying efficiency compared to open drying devices.

[0024] Please see Figure 1 and Figure 3 In this embodiment, rollers 24 are installed at the four corners of the bottom of the base plate 21, and a first handle 231 is fixedly connected to the center of the two side baffles 23 on the side away from each other. The size of the two side baffles 23 is adapted to the size of the drying channel 11, the width of the bottom plate 21 is adapted to the width of the drying channel 11, and the four corners of the bottom plate 21 are all rounded chamfers.

[0025] Roller 24 refers to the universal wheel assembly installed at the bottom of the base plate 21. In this embodiment, it is a polyurethane-edged bearing wheel equipped with a foot brake mechanism. The first handle 231 is a U-shaped grip on the outer side of the side baffle 23, made of ABS engineering plastic, with anti-slip texture on the inner side. The drying channel 11 specifically refers to the rectangular channel space for material transfer inside the equipment. The arc chamfer refers to the R20-R25mm rounded transition structure at the four corners of the base plate 21, and the chamfer surface is sandblasted to enhance wear resistance. The side baffle 23 is a 2mm thick 304 stainless steel bent part with a high-temperature resistant ceramic coating sprayed on the surface. The rollers 24 are connected to the reinforcing ribs at the four corners of the base plate 21 via M8 high-strength bolts. The first handle 231 is fixed to the side baffle 23 using a back-through bolt and a positioning pin. The handle's inner cavity is filled with sound-insulating foam material. The width fit between the base plate 21 and the drying channel 11 is designed to be 3-5mm, with three PTFE wear-resistant strips on each side. The curved chamfer is continuously laser-welded to the main body of the base plate 21, and stress relief treatment is performed after welding. A 5mm thick silicone rubber sealing strip is provided on the lower edge of the side baffle 23, forming a compression seal with the contact surface of the base plate 21. The size of the two side baffles 23 is adapted to the size of the drying channel 11, including dynamic matching requirements: under operating conditions of 80℃, the thermal expansion of the side baffles 23 needs to be controlled within 0.8mm through finite element simulation. For this purpose, three sets of elongated mounting holes are provided in the side baffles 23, allowing for lateral thermal displacement compensation of ±1.2mm. The design of the curved chamfers must meet ergonomic requirements, with the radius of the arc matching the results of collision tests on the operator's lower leg to ensure no risk of sharp-angle injury. The combination of rollers 24 and handles enables convenient movement and positioning of the equipment, improving handling efficiency compared to traditional fixed structures; the precisely fitted side baffles 23 and drying channel 11 form a closed heat circulation system, improving heat energy utilization; the arc-shaped chamfer design reduces cleaning dead corners and avoids jamming during material conveying.

The multiple storage rods 222 are all arranged in an L-shape, and the multiple storage rods 222 on the same upright rod 221 are arranged in a staggered manner.

[0027] The n-shaped support frame 223 refers to a portal frame structure composed of two vertical beams and one horizontal beam. In this embodiment, it can be made of aluminum alloy profiles or galvanized steel pipes. The uprights 221 are round tubes with a diameter of 20-25mm, preferably made of 304 stainless steel, and are fixed to the base plate 21 by welding. The L-shaped structure of the storage rods 222 has a short side length of 50-80mm and a long side length of 200-300mm. The staggered arrangement means that the horizontal projection distance between adjacent storage rods 222 is 1.2-1.5 times the width of the rod, forming a stepped layout. The combination of the n-shaped support frame 223 and the upright 221 forms a three-dimensional load-bearing structure; the staggered arrangement of the L-shaped storage rods 222 improves space utilization and avoids the accumulation and collision of items.
