Description

Technical Field

[0001] This application relates to the technical field of aluminum panel processing, and in particular to a uniform spraying device for processing aluminum panels for curtain walls. Background Technology

[0002] A curtain wall is the exterior cladding of a building, hung like a curtain, hence also called a suspended wall. Most curtain walls are made of aluminum, and aluminum single panels refer to building decoration materials that have undergone chromating and other treatments, followed by fluorocarbon spraying technology. Fluorocarbon coating has excellent corrosion resistance and weather resistance, resisting acid rain, salt spray and various air pollutants. It also has excellent resistance to hot and cold temperatures, can withstand strong ultraviolet radiation, and can maintain its color and prevent chalking for a long time, resulting in a long service life.

[0003] The related technology, disclosed in CN221847632U, describes a uniformly sprayable aluminum single-panel curtain wall spraying device. It includes a base, with a frame for auxiliary support mounted on the top surface of the base. A branch pipe for flow guidance is bolted to the inner circumference of the frame. When the belt operates and slowly transports the aluminum single-panel to the bottom of the frame at the top of the base, the corresponding pump operates to easily extract the paint and transport it to the inner side of the branch pipe. Before this, the valves at corresponding positions on the outer circumference of the branch pipe are adjusted so that the nozzles at those positions can spray the paint. The U-shaped nozzles facilitate spraying the outer surface of the aluminum single-panel. Simultaneously, the slow conveyor belt improves the uniformity of the paint spraying and reduces uneven thickness during surface coating. Furthermore, the empty groove at the top of the base facilitates the collection of excess paint for recycling.

[0004] Although the uniform spraying device for processing aluminum single panels in the above-mentioned technology can spray aluminum single panels through U-shaped nozzles, the nozzle position is fixed. This makes it difficult to achieve all-round spraying once the movement direction of the aluminum single panel is fixed, which may cause problems such as uneven spraying, excessively thick or thin spraying in some areas, affecting the overall aesthetics and performance of the aluminum single panel. Utility Model Content

[0005] To address the limitations of current uniform spraying devices used for processing aluminum curtain wall panels, the inventors have discovered that while these devices can spray aluminum panels using U-shaped nozzles, the fixed nozzle positions make it difficult to achieve omnidirectional spraying once the aluminum panel's movement direction is fixed. This can lead to uneven spraying, excessively thick or thin coating in certain areas, and negatively impact the overall aesthetics and performance of the aluminum curtain wall panels. Therefore, this application provides a uniform spraying device for processing aluminum curtain wall panels.

[0006] The uniform spraying device for processing aluminum single-panel curtain walls provided in this application adopts the following technical solution: it includes a frame, a support turntable disposed on one side of the frame, a rotating shaft connected to the support turntable, a spraying mechanism disposed on the other side of the frame and disposed relative to the support turntable, a mounting base for installing the spraying mechanism, a support base slidably connected to the mounting base, and a drive assembly for driving the rotating shaft and the mounting base.

[0007] The drive assembly includes a gear shaft fixedly disposed at the middle position of the rotating shaft, a gear meshing with the gear shaft, a connecting shaft connected to the gear, a first pulley connected to the other end of the connecting shaft, a drive motor disposed outside the first pulley and connected to the connecting shaft, a transmission belt connected to the first pulley, a second pulley connected to the other end of the transmission pulley, a traction shaft connected to the other end of the second pulley, a first traction plate hinged to the other end of the traction shaft, and a second traction plate hinged to the other end of the first traction plate. The second traction plate is connected to the mounting base.

[0008] By adopting the above technical solution, the drive motor first rotates the connecting shaft, and through the meshing transmission of gears and gear shafts, the rotating shaft drives the support turntable to rotate, and the support turntable drives the aluminum single panel to rotate synchronously; at the same time, the connecting shaft drives the transmission belt to move through the first pulley, and the transmission belt rotates the second pulley, thereby driving the traction shaft to rotate. Through the linkage movement formed by the first traction plate and the second traction plate, the mounting base is driven to move up and down reciprocally, and finally the spraying mechanism can perform all-round spraying operation on the rotating aluminum single panel.

[0009] As a preferred embodiment, the supporting turntable is configured as either a vacuum chuck or a magnetic chuck, and the vacuum chuck or magnetic chuck is configured as an embedded type.

[0010] By adopting the above technical solution, the function of the support turntable is to support the aluminum panel and fix it to the support turntable by the built-in vacuum suction cup or magnetic suction cup; the function of the vacuum suction cup or magnetic suction cup is to firmly adsorb the aluminum panel onto the support turntable by negative pressure or magnetic force, so as to ensure that the aluminum panel will not slide or fall off during the spraying process.

[0011] As a preferred embodiment, one end of the rotating shaft is fixedly connected to the supporting turntable, and a bearing seat is provided at the connection point between the other end of the rotating shaft and the frame.

[0012] By adopting the above technical solution, since the rotating shaft is connected to the support turntable through a fixed connection, and a bearing seat is installed at the end of the rotating shaft connected to the frame, the rotating shaft can rotate smoothly, and the support turntable can rotate 360 ​​degrees as needed, which facilitates the circumferential rotation of the aluminum single panel.

[0013] As a preferred embodiment, the connecting shaft passes through the frame and connects with the gear, and a sealed bearing is provided at the connection between the connecting shaft and the frame.

[0014] By adopting the above technical solution, the drive motor drives the connecting shaft to rotate, and the rotating connecting shaft drives the sealed bearing to rotate together. Since the sealed bearing is installed at the connection between the frame and the connecting shaft, it can provide stable support and ensure the sealing of the connection. Subsequently, the rotational motion of the connecting shaft is transmitted to the gear through the sealed bearing, causing the gear to rotate accordingly.

[0015] As a preferred embodiment, a fixed base is provided at the connection between the drive motor and the frame, and the fixed base is fixedly connected to the frame.

[0016] By adopting the above technical solution, the drive motor is securely connected to the frame through its fixed base, ensuring the installation stability of the drive motor.

[0017] As a preferred embodiment, the first pulley and the second pulley are respectively connected to the rotating shaft and the connecting shaft through a spline structure, and the first pulley and the second pulley are provided with grooves adapted to the transmission belt.

[0018] By adopting the above technical solution, the groove design on the first and second pulleys allows the transmission belt to be firmly embedded without easily falling off, thereby ensuring the effective transmission of power.

[0019] As a preferred embodiment, the first traction plate and the second traction plate are connected by a rotating pin, and the rotating pin is rotatably connected to the first traction plate and the second traction plate respectively.

[0020] By adopting the above technical solution, the reciprocating motion of the mounting base can be achieved by controlling the relative rotation angle between the first traction plate and the second traction plate. At the same time, the free rotation characteristic of the rotating pin ensures smoothness and stability during the traction process and reduces friction and wear during the traction process.

[0021] As a preferred embodiment, the support base is provided with a sliding groove that is adapted to the mounting base, and the sliding groove is arranged in the height direction of the support base.

[0022] By adopting the above technical solution, the slide groove design is used to precisely match the mounting base, so that the mounting base can slide smoothly in the height direction of the support base.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. The support turntable is connected to the frame via a rotating shaft, enabling it and the aluminum panels fixed on it to rotate.

[0025] 2. The spraying mechanism is located on one side of the frame and is responsible for spraying the rotating aluminum panels; the mounting base is used to fix and adjust the position of the spraying mechanism; the support base is slidably connected to the mounting base and plays a guiding role to ensure the accurate up and down movement path of the spraying mechanism.

[0026] 3. The drive assembly includes a gear shaft, gears, a connecting shaft, a first pulley, a drive motor, a transmission belt, a second pulley, and a traction shaft. The drive motor first rotates the connecting shaft, and through the meshing transmission of the gears and gear shaft, the rotating shaft drives the support turntable to rotate, and the support turntable drives the aluminum panel to rotate synchronously. At the same time, the connecting shaft drives the transmission belt to move through the first pulley, and the transmission belt rotates the second pulley, thereby driving the traction shaft to rotate. Through the linkage movement formed by the first traction plate and the second traction plate, the mounting base is driven to move up and down reciprocally, ultimately realizing the spraying mechanism to perform all-round spraying operation on the rotating aluminum panel.

The support turntable 2 is mounted on one side of the frame and can rotate freely around the rotating shaft 51, improving the uniformity and flexibility of the sprayed coating. The rotating shaft 51 is connected to the support turntable 2 and drives its rotation. The spraying mechanism 3 is located on the other side of the frame, opposite the support turntable 2, and is used to spray paint to coat the aluminum panels. The mounting base 31 is used to fix the spraying mechanism 3 and ensure its accurate positioning during operation. The support base 4 is slidably connected to the mounting base 31, allowing the spraying mechanism 3 to move in the horizontal direction and increasing the coverage of the sprayed coating. The drive assembly is used to drive the rotation shaft 51 and the mounting base 31 to achieve synchronous and coordinated control of the support turntable 2 and the spraying mechanism 3, thereby ensuring the high efficiency and flexibility of the spraying operation and improving the spraying quality and production efficiency.

[0035] Please refer to details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The drive assembly includes a gear shaft 511 fixedly mounted at the middle of the rotating shaft 51, a gear 52 meshing with the gear shaft 511, a connecting shaft 521 connected to the gear 52, a first pulley 61 connected to the other end of the connecting shaft 521, a drive motor 611 located outside the first pulley 61 and connected to the connecting shaft 521, a transmission belt connected to the first pulley 61, a second pulley 62 connected to the other end of the transmission pulley, a traction shaft connected to the other end of the second pulley 62, a first traction plate 71 hinged to the other end of the traction shaft, and a second traction plate 71 hinged to the other end of the first traction plate 71. The guide plate 72 and the second traction plate 72 are connected to the mounting base 31. In this utility model, the drive motor 611 first rotates the connecting shaft 521. Through the meshing transmission of the gear 52 and the gear shaft 511, the rotating shaft 51 drives the support turntable 2 to rotate, and the support turntable 2 drives the aluminum single panel to rotate synchronously. At the same time, the connecting shaft 521 drives the transmission belt to move through the first pulley 61. The transmission belt rotates the second pulley 62, thereby driving the traction shaft to rotate. Through the linkage movement formed by the first traction plate 71 and the second traction plate 72, the mounting base 31 is driven to move up and down reciprocally, and finally the spraying mechanism 3 performs all-round spraying operation on the rotating aluminum single panel.

[0036] Please refer to details. Figure 1 and Figure 2 The support turntable 2 is set as either a vacuum suction cup or a magnetic suction cup, and the vacuum suction cup or magnetic suction cup is set as an embedded type. The function of the support turntable 2 is to support the aluminum single panel and fix it to the support turntable 2 by the built-in vacuum suction cup or magnetic suction cup. The function of the vacuum suction cup or magnetic suction cup is to firmly adsorb the aluminum single panel onto the support turntable 2 by negative pressure or magnetic force, so as to ensure that the aluminum single panel will not slide or fall off during the spraying process.

Figure 3 , Figure 4 and Figure 5 One end of the rotating shaft 51 is fixedly connected to the support turntable 2, and a bearing seat is provided at the connection point between the other end of the rotating shaft 51 and the frame 1. Since the rotating shaft 51 is fixedly connected to the support turntable 2, and a bearing seat is installed at the end of the rotating shaft 51 connected to the frame 1, the rotating shaft 51 can rotate smoothly, and the support turntable 2 can rotate 360 ​​degrees as needed, which facilitates the circumferential rotation of the aluminum single panel.

A sealed bearing is provided at the connection between the connecting shaft 521 and the frame 1. The drive motor 611 drives the connecting shaft 521 to rotate. The rotation of the connecting shaft 521 drives the sealed bearing to rotate together. Since the sealed bearing is installed at the connection between the frame 1 and the connecting shaft 521, it can provide stable support and ensure the sealing of the connection. Subsequently, the rotational motion of the connecting shaft 521 is transmitted to the gear 52 through the sealed bearing, causing the gear 52 to rotate accordingly.

Figure 5 The first traction plate 71 and the second traction plate 72 are connected by a rotating pin, and the rotating pin is rotatably connected to the first traction plate 71 and the second traction plate 72 respectively. By controlling the relative rotation angle between the first traction plate 71 and the second traction plate 72, the up-and-down reciprocating motion of the mounting base 31 can be realized. At the same time, the free rotation characteristic of the rotating pin ensures the smoothness and stability of the traction process and reduces friction and wear during the traction process.

[0042] Please refer to details. Figure 5 The support base 4 is provided with a sliding groove 41 that is adapted to the mounting base 31, and the sliding groove 41 is set in the height direction of the support base 4.

[0043] The implementation principle of a uniform spraying device for processing aluminum single-panel curtain walls according to an embodiment of this application is as follows: In use, the aluminum single-panel is placed on the support turntable 2. The drive motor 611 first rotates the connecting shaft 521. Through the meshing transmission of the gear 52 and the gear shaft 511, the rotating shaft 51 drives the support turntable 2 to rotate, and the support turntable 2 drives the aluminum single-panel to rotate synchronously. At the same time, the connecting shaft 521 drives the transmission belt to move through the first pulley 61.
