Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, specifically to an efficient aluminum alloy surface painting equipment. Background Technology

[0002] Aluminum alloy is a metallic material with many excellent properties such as light weight, high strength, easy processing, thermal conductivity, electrical conductivity and good toughness. It is often used in the manufacture of building materials, automotive parts, electronics industry, aerospace and other mechanical equipment. In order to improve the corrosion resistance and aesthetics of aluminum alloy, the surface of aluminum alloy is usually coated.

[0003] Utility model patent CN221869022U discloses a surface treatment device for aluminum alloy processing. When spraying aluminum alloy, it can automatically rotate the aluminum alloy, ensuring that all surfaces are coated. It is convenient to use, reduces labor intensity, and is highly practical. The device includes a base plate, a support plate, a servo motor, a rotating shaft, a clamping mechanism, a drying mechanism, a moving mechanism, and a spraying mechanism. The support plate is mounted on the base plate via the moving mechanism, which moves the support plate left and right. The servo motor is fixedly mounted on the support plate, and the rotating shaft is rotatably mounted on the servo motor. The input end of the rotating shaft is connected to the servo motor. The clamping mechanism is mounted on the rotating shaft and has a clamping function. The drying mechanism is mounted on the base plate and has a drying function. The spraying mechanism is mounted on the base plate and has a spraying function.

[0004] However, although the above-mentioned device can achieve double-sided painting of aluminum alloy surfaces, the double-sided painting of the device is carried out by flipping the aluminum alloy material and painting it again after painting one surface. In addition, multiple bolts need to be moved sequentially when installing and removing the aluminum alloy material, resulting in low painting efficiency of aluminum alloy materials, which is difficult to meet the usage requirements. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an efficient painting equipment for aluminum alloy surfaces to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A high-efficiency aluminum alloy surface spraying equipment includes a base, two mounting plates fixed on the top of the base, a conveying mechanism on the top of the base, an adjustment mechanism on the surface of the mounting plates, a drive mechanism and a spraying mechanism on the top of the base, and a controller fixed on the surface of the mounting plates.

[0008] The conveying mechanism includes two opposing side plates, which are fixed to the top of the base. Two drive shafts are rotatably connected to the surface of the side plates, and multiple driven shafts are rotatably connected to the surface of the side plates. Both the drive shafts and driven shafts are rotatably connected to the surface of the mounting plate. A double-groove pulley is fixed to the surface of the driven shaft, and the multiple double-groove pulleys are connected by belt drive. A transmission pulley is fixed to the surface of the drive shaft, and the transmission pulley is connected to the surface of one of the double-groove pulleys by belt drive. Lower conveying rollers are fixed to the surfaces of both the drive shaft and the driven shaft. An L-shaped plate is provided above the side plates, and multiple upper conveying rollers are rotatably connected to the surface of the L-shaped plate.

[0009] Preferably, the adjustment mechanism includes a hydraulic cylinder, which is fixed to the top of the mounting plate. One end of the hydraulic cylinder passes through the mounting plate and is fixed with a pressure sensor. The bottom of the pressure sensor is fixedly connected to the top of the L-shaped plate.

[0010] Preferably, a plurality of guide rods slide through the top of the mounting plate, and the bottom of the guide rods is fixedly connected to the top of the L-shaped plate.

[0011] Preferably, the drive mechanism includes two mounted bearings, which are fixedly connected to the top of the base. A transmission rod is fixed to the inner wall of the mounted bearing. A geared motor is fixed to the top of the base. The output shaft of the geared motor is fixedly connected to one end of the transmission rod. Two lower sprockets are fixed to the surface of the transmission rod. An upper sprocket is connected to the surface of the lower sprockets via a chain drive. The upper sprocket is fixed to the surface of a drive shaft on one side.

[0012] Preferably, a rubber sleeve is fixed to the surface of both the lower conveyor roller and the upper conveyor roller.

[0013] Preferably, the painting mechanism includes a lower splitter pipe and an upper splitter pipe. Multiple high-pressure fan-shaped nozzles are connected to the surfaces of both the lower and upper splitter pipes. A support plate is fixed to the surface of the lower splitter pipe, and the bottom of the support plate is fixedly connected to the surface of the base.

[0014] Preferably, the number of upper conveying rollers is the same as the number of lower conveying rollers.

[0015] Compared with existing technologies, the advantages of this utility model's high-efficiency aluminum alloy surface painting equipment are:

[0016] First, by using double-sided synchronous painting, the problem of having to flip the board in the traditional process is solved, resulting in higher painting efficiency. The continuous motion design of the conveying mechanism, combined with the synchronous control of the drive mechanism, forms a clamping channel with the upper and lower conveying rollers above the L-shaped board. The board is continuously conveyed by friction as it passes through, and in conjunction with the painting mechanism, the painting effect is achieved during the conveying of the board. In addition, the rubber sleeve can increase the contact area with the board through elastic deformation, which can improve friction and buffer mechanical vibration.

[0017] Secondly, the adjustment mechanism drives the pressure sensor and the L-shaped plate to move up and down through the hydraulic cylinder. The pressure sensor monitors the clamping pressure in real time and feeds it back to the controller to prevent excessive squeezing from causing deformation of the plate. This achieves automated clamping height adjustment and ensures that the plate has sufficient friction for conveying. Attached Figure Description

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-6 A high-efficiency aluminum alloy surface spraying equipment includes a base 1, two mounting plates 2 fixed on the top of the base 1, a conveying mechanism 3 provided on the top of the base 1, an adjustment mechanism 4 provided on the surface of the mounting plates 2, a drive mechanism 5 and a spraying mechanism 6 provided on the top of the base 1, and a controller 7 fixed on the surface of the mounting plates 2.

[0027] The conveying mechanism 3 includes two opposing side plates 301, which are fixed to the top of the base 1. Two drive shafts 302 are rotatably connected to the surface of the side plates 301, and multiple driven shafts 303 are rotatably connected to the surface of the side plates 301. Both the drive shafts 302 and the driven shafts 303 are rotatably connected to the surface of the mounting plate 2. A double-groove pulley 304 is fixed to the surface of the driven shaft 303, and the multiple double-groove pulleys 304 are connected by belt drive. A transmission pulley 305 is fixed to the surface of the drive shaft 302, and the transmission pulley 305 is connected to the surface of the double-groove pulley 304 on one side by belt drive. Lower conveying rollers 306 are fixed to the surfaces of both the drive shaft 302 and the driven shaft 303. An L-shaped plate 307 is provided above the side plates 301, and multiple upper conveying rollers 308 are rotatably connected to the surface of the L-shaped plate 307.

[0028] Through the above technical solution, the drive mechanism 5 can drive two drive shafts 302 to rotate. The drive shafts 302 drive the double groove pulleys 304 to rotate synchronously through the transmission pulleys 305, which in turn drive the driven shaft 303 to drive the lower conveyor rollers 306 in conjunction, so that multiple lower conveyor rollers 306 can rotate synchronously. The upper conveyor roller 308 above the L-shaped plate 307 and the lower conveyor rollers 306 form a clamping channel. When the plate passes through, it is continuously conveyed by friction. The painting mechanism 6 can achieve simultaneous spraying on the front side of the plate, so that the two-sided spraying effect can be quickly completed without stopping and flipping, thereby improving the processing efficiency of aluminum alloy plates.

[0029] The adjustment mechanism 4 includes a hydraulic cylinder 401, which is fixed to the top of the mounting plate 2. One end of the hydraulic cylinder 401 passes through the mounting plate 2 and is fixed with a pressure sensor 402. The bottom of the pressure sensor 402 is fixedly connected to the top of the L-shaped plate 307.

[0030] Through the above technical solution, the adjustment mechanism 4 drives the pressure sensor 402 and the L-shaped plate 307 to move up and down through the hydraulic cylinder 401. The pressure sensor 402 monitors the clamping pressure in real time and feeds it back to the controller 7 to prevent excessive squeezing from causing deformation of the plate, realizes automatic clamping height adjustment, and ensures that the plate has sufficient friction for conveying.

[0031] Multiple guide rods 403 slide through the top of the mounting plate 2, and the bottom of the guide rods 403 are fixedly connected to the top of the L-shaped plate 307.

[0032] Through the above technical solution, the guide rod 403 restricts the displacement direction of the L-shaped plate 307, ensuring that the upper conveying roller 308 and the lower conveying roller 306 remain parallel, thus eliminating the risk of lateral deviation.

[0033] The drive mechanism 5 includes two seated bearings 501, which are fixedly connected to the top of the base 1. A transmission rod 502 is fixed to the inner wall of the seated bearing 501. A geared motor 503 is fixed to the top of the base 1. The output shaft of the geared motor 503 is fixedly connected to one end of the transmission rod 502. Two lower sprockets 504 are fixed to the surface of the transmission rod 502. An upper sprocket 505 is connected to the surface of the lower sprockets 504 via a chain drive. The upper sprocket 505 is fixed to the surface of a drive shaft 302 on one side.

[0034] Through the above technical solution, the bearing 501 fixes the position of the transmission rod 502 to ensure the coaxiality of power transmission. The geared motor 503 outputs power to the transmission rod 502, and drives the drive shafts 302 on both sides to rotate through the chain transmission of the lower sprocket 504 and the upper sprocket 505, thereby ensuring that multiple lower conveyor rollers 306 can rotate.

[0035] Both the lower conveyor roller 306 and the upper conveyor roller 308 have a layer of rubber sleeve fixed on their surfaces.

[0036] Through the above technical solution, the rubber sleeve can increase the contact area with the plate through elastic deformation, thereby improving friction and buffering mechanical vibration.

[0037] The painting mechanism 6 includes a lower split pipe 601 and an upper split pipe 602. Multiple high-pressure fan-shaped nozzles 605 are connected to the surfaces of both the lower split pipe 601 and the upper split pipe 602. A support plate 603 is fixed to the surface of the lower split pipe 601. The bottom of the support plate 603 is fixedly connected to the surface of the base 1. A support frame 604 is fixed to the surface of the upper split pipe 602. The surface of the support frame 604 is fixedly connected to the surface of the mounting plate 2. A guide pipe 606 is connected to the surfaces of both the upper split pipe 602 and the lower split pipe 601. A connector 607 is connected to the surface of the guide pipe 606.

[0038] Through the above technical solution, the support plate 603 and the support frame 604 fix the painting assembly, the lower diversion pipe 601 and the upper diversion pipe 602 are connected to the external paint source through the connector 607 on the surface of the guide pipe 606, and the high-pressure fan-shaped nozzle 605 covers the surface of the board with a wide diffusion angle, so as to achieve the synchronous painting effect on the front and back of the board.

[0039] The number of upper conveyor rollers 308 is the same as the number of lower conveyor rollers 306.

[0040] With the above technical solution, the upper conveying roller 308 and the lower conveying roller 306 are the same in number and symmetrically distributed, which can form a uniform clamping force field and avoid uneven local stress on the plate.

[0041] Pressure sensor 402, hydraulic cylinder 401 and geared motor 503 are all electrically connected to controller 7.

[0042] In use, the equipment uses the upper and lower rollers of the conveying mechanism 3 to clamp the aluminum alloy sheet and move it continuously. The sprocket system of the drive mechanism 5 provides synchronous power, and the adjustment mechanism 4 controls the clamping pressure in real time. When the sheet enters the painting area, the lower diversion pipe 601 and the upper diversion pipe 602 of the painting mechanism 6 spray paint through the high-pressure fan-shaped nozzle 605 at the same time, so that the paint is sprayed onto the front and back of the sheet at the same time, realizing the effect of rapid simultaneous painting of the front and back of the sheet. No manual flipping or bolt fixing is required throughout the process, which greatly improves the painting efficiency of aluminum alloy sheets.
