Description
Technical Field
[0001] This utility model belongs to the field of aluminum profile processing technology, specifically a suspension device and transfer device for aluminum profile spraying. Background Technology
[0002] Aluminum profiles, with their excellent properties such as low density, high strength, corrosion resistance, ease of processing, and recyclability, have been widely used in various fields including building decoration, transportation, electronics, and machinery manufacturing. As modern industry continues to demand higher material performance and the concept of green manufacturing is deeply promoted, the application scenarios for aluminum profiles are constantly expanding, and the requirements for their structural design, functional integration, and processing technology are becoming increasingly stringent.
[0003] Common aluminum profiles are mainly produced by melting and casting to form cylindrical aluminum ingots with different material formulas. Then, the oxide layer on the surface is removed by a car body. The aluminum billet is then transferred to the downstream for specific product processing. First, the aluminum billet is heated in a heating furnace, then slit, and after slit, it is extruded and shaped by a mold. The shaped aluminum material is straightened, and then surface treatments such as spraying are carried out to improve the aesthetics and corrosion resistance of the profile.
[0004] However, existing suspension devices typically suspend aluminum profiles on a rack and keep them stationary before spraying. When spraying at different angles, it is necessary for a person to stand in different positions with the spraying tool, which is inconvenient to change the angle of the aluminum profile. This results in reliance on manual spraying, making it impossible to automate the spraying process. In addition, manual spraying has poor consistency, and the inhalation of paint is harmful to the human body. Utility Model Content
[0005] To address the problems of existing aluminum profile spraying suspension devices where the angle of the suspended aluminum profiles cannot be adjusted, requiring manual multi-angle spraying, inconsistent spraying, and the health hazards of paint to spraying personnel, this utility model provides a suspension device and transfer device for aluminum profile spraying.
[0006] This utility model is achieved through the following technical solution: The first aspect of this utility model provides a suspension device for aluminum profile spraying, including two connecting frames that can be fixedly installed relative to each other, an installation frame rotatably connected to the lower side of the connecting frames, a plurality of retaining blocks rotatably connected to the inner sidewalls of the two installation frames, and gears rotatably connected to and installed in the installation frames and connected to the corresponding retaining blocks, with adjacent gears meshing with each other. Two first pulleys are rotatably connected and installed on the connecting frame. One first pulley is fixedly connected to a gear on the corresponding mounting frame. The two first pulleys are connected by a first belt drive. A drive shaft is connected and installed on the outside of the first pulley. It also includes a power unit that can drive the drive shaft to rotate.
[0007] A further improvement of this utility model is that a support block is rotatably connected to the holding block, and a second spring is installed between the support block and the holding block.
[0008] A further improvement of this utility model is that rubber pads are provided on the outer sides of both the support block and the clamping block.
[0009] The second aspect of this utility model provides a transfer device, including a fixed frame with an installation channel in the middle and the above-mentioned suspension device for aluminum profile spraying. The power device includes a first motor connected and installed on the fixed frame, an active friction disc connected and installed at the output end of the first motor, and a driven friction disc slidably connected and installed on the transmission shaft to be able to rub and transmit with the active friction disc. A first spring is sleeved on the transmission shaft to elastically support the driven friction disc to the side away from the connecting frame. The upper side of the fixed frame is connected to two corresponding sliding grooves, and the sides of the fixed frame are connected to retainers. Both retainers are rotatably connected to sprockets, and the two sprockets are connected to each other by chain drive. Several sliders that slide in cooperation with the sliding grooves on both sides are connected to the chain. Connecting seats are connected to the lower side of the sliders. The connecting seats are detachably connected to the connecting block fixedly installed on the upper side of the connecting frame. A second motor is connected to one side of the fixed frame, and the second motor is connected to the sprocket through a transmission mechanism.
[0010] A further improvement of this utility model is that a limit switch is provided on the lower side of the slide.
[0011] A further improvement of this utility model is that the transmission mechanism includes a second pulley connected and installed at the output end of the second motor, and a third pulley connected and installed on the outside of the sprocket. The second pulley and the third pulley are connected by a second belt drive.
[0012] As can be seen from the above technical solutions, the beneficial effects of this utility model are: In use, a pair of suspension devices are fixed to the aluminum profile using clamping blocks. A crane hook then uses the upper connecting blocks to insert the two suspension devices into the connecting seat, allowing the suspension devices to suspend. The second motor is started, driving the sprocket through a transmission mechanism. The sprocket's rotation causes the slider to slide within a groove, which in turn moves the suspension device via the connecting blocks and connecting seat. When the driven friction disc contacts the driving friction disc, the second motor stops, and the first motor drives the driving friction disc to rotate. The driving friction disc, through friction, drives the driven friction disc to rotate, which in turn drives the first pulley to rotate. This, in turn, drives the first pulley on the other side via a first belt. The first pulley then drives the meshing gears, ultimately causing the clamping blocks to rotate the aluminum profile. This device achieves automatic rotation of the aluminum profile to be sprayed, eliminating the need to change angles during spraying to ensure uniform coating, reducing labor intensity, and easily linking with single-angle spraying machines to replace manual spraying of aluminum profiles. This significantly improves spraying efficiency and consistency of spraying quality, and avoids injury to personnel during spraying. Attached Figure Description

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0022] like Figure 1 , 2 As shown in Figure 5, this utility model discloses a suspension device for aluminum profile spraying, including two connecting frames 2 that can be fixedly installed relative to each other, and an installation frame 1 rotatably connected to the lower side of the connecting frame 2. The feature is that a plurality of clamping blocks 3 are rotatably connected to the inner sidewalls of the two installation frames 1, and gears 4 connected to the corresponding clamping blocks 3 are rotatably connected to the installation frame 1, and adjacent gears 4 mesh with each other. Two first pulleys 5 are rotatably connected and installed on the connecting frame 2. One first pulley 5 is fixedly connected to a gear 4 on the corresponding mounting frame 1. The two first pulleys 5 are connected by a first belt 6. A drive shaft 7 is connected and installed on the outside of the first pulley 5. It also includes a power unit 71 that can drive the drive shaft 7 to rotate.
[0023] In use, this device can be suspended in pairs on the transfer device. The aluminum profile is mounted on two clamping blocks 3 on the two sides of the rectangular inner cavity, respectively, to suspend the aluminum profile in the rectangular inner cavity. The power device 71 drives the transmission shaft 7 to rotate, and the transmission shaft 7 drives the first pulley 5 to rotate. The first pulley 5 drives the first pulley 5 on the other side to rotate through the first belt 6. The first pulley 5 drives all the clamping blocks 3 to rotate together through the meshing gear 4, so as to realize the continuous rotation of the aluminum profile itself. It can uniformly spray the entire surface of multiple aluminum profiles, improve the efficiency and quality of spraying, and reduce the labor intensity and inconvenience caused by manual spraying at multiple angles.
[0024] It should be noted that the aluminum profile is fixed by two sets of opposing suspension devices. The entire aluminum profile is rotated by rotating one side, thus achieving the axial rotation of the aluminum profile. The suspension device on the other side only needs to support and rotate, without the need for transmission structures such as pulleys and gears. In addition, the connecting frame 2 can separate the painting part from the transmission part, preventing the painting from affecting the power unit 71.
[0025] A support block 11 is rotatably connected to the clamping block 3, and a second spring 12 is connected between the support block 11 and the clamping block 3. This allows aluminum profiles of different inner diameters to be sprayed to be mounted on the clamping block 3. The support block 11, supported by the second spring 12, fixes the aluminum profiles of different inner diameters, so that the aluminum profiles can rotate together with the clamping block 3.
[0026] Both the support block 11 and the retaining block 3 are provided with rubber pads 13 on their outer sides. The rubber pads 13 can protect the aluminum profile from wear when supported by the support block 11, and at the same time, the rubber pads 13 can improve the firmness of the support block 11.
[0027] like Figure 1-6 As shown, this utility model also discloses a transfer device, including a fixed frame 14 with an installation channel in the middle and the above-mentioned suspension device for aluminum profile spraying. The power device 71 includes a first motor 15 connected and installed on the fixed frame 14. An active friction disk 16 is connected and installed at the output end of the first motor 15. It also includes a driven friction disk 8 that is slidably connected and installed on the transmission shaft 7 and can rub and drive with the active friction disk 16. The driven friction disk 8 is provided with a keyway and slides with the key on the transmission shaft 7 to realize transmission. A first spring 9 is sleeved on the transmission shaft 7 to elastically support the driven friction disk 8 to the side away from the connecting frame 2. Two corresponding slide grooves 17 are connected and installed on the upper side of the fixed frame 14. Retainers 18 are connected and installed on both sides of the fixed frame 14. Sprockets 19 are rotatably connected and installed on both retainers 18. The two sprockets 19 are connected and driven by a chain 20. Several sliders 21 that slide in cooperation with the slide grooves 17 on both sides are connected and installed on the chain 20. Connecting seats 211 are connected and installed on the lower side of the sliders 21. The connecting seats 211 are detachably connected to the connecting block 10 fixedly installed on the upper side of the connecting frame 2. A second motor 22 is connected and installed on one side of the fixed frame 14. The second motor 22 is connected and driven by the sprockets 19 through a transmission mechanism 23.
[0028] In use, a pair of suspension devices are inserted into the connecting seat 211 via the upper connecting block 10, allowing the suspension devices to be suspended. The aluminum profile is placed on the clamping block 3, allowing the aluminum profile to be placed horizontally. The second motor 22 is started, driving the sprocket 19 to rotate through the transmission mechanism 23. The rotation of the sprocket 19 drives the chain 20 to rotate, and the chain 20 drives the slider 21 to slide in the slide groove 17. Then, the suspension device is moved through the connecting block 10 and the connecting seat 211. When the driven friction disc 8 and the active friction disc 16 are tightly fitted, the device is in the spraying position. The first motor 15 drives the active friction disc 16 to rotate. The active friction disc 16 rotates, driving the driven friction disc 8 to rotate via friction. This, in turn, drives the first pulley 5 to rotate, which in turn drives the other first pulley 5 to rotate via the first belt 6. The first pulley 5 then drives the meshing gear 4 to rotate, thereby causing the clamping block 3 to rotate the aluminum profile. The spraying equipment then sprays paint. After spraying, the second motor 22 is started to reverse, allowing the aluminum profile to enter the baking paint chamber for baking paint. Then, it returns to its initial position, and simultaneously, the suspension devices on both sides are removed by a crane. The suspension devices are then moved away, allowing the aluminum profile to be removed. Protective measures should be taken to prevent paint abrasion. This device achieves automated transfer of the aluminum profile to be sprayed and enables the aluminum profile to rotate on its own. This eliminates the need to change various angles during spraying to ensure uniform spraying. It is easy to link with a single-angle spraying machine to replace manual spraying of aluminum profiles, greatly improving spraying efficiency and consistency of spraying quality.
[0029] The slide 17 has a limit switch 24 on its lower side. When the connecting block 10 moves to the point where the driven friction disc 8 can connect with the active friction disc 16, the connecting block 10 will touch the limit switch 24, causing the second motor to stop running and the first motor 15 to start. This can automatically control the device to complete the movement and rotation of the aluminum profile, avoiding malfunctions caused by excessive rotation.
[0030] The transmission mechanism 23 includes a second pulley 231 connected to and installed at the output end of the second motor 22, and a third pulley 232 connected and installed on the outside of the sprocket 19. The second pulley 231 and the third pulley 232 are connected by a second belt 233. The second motor 22 drives the second pulley 231 to drive the third pulley 232 to rotate via the second belt 233. The belt drive can protect the motor, prevent motor overload, and also enable long-distance power transmission, allowing the motor to be installed more reasonably on the fixed frame 14 and ensuring that the motor is in a suitable working environment.
[0031] In use, multiple aluminum profiles to be coated are placed on the clamping block 3 and held in place. The overhead crane clamps the suspension devices on both sides, and the connecting block 10 is inserted into the connecting seat 211. The second motor 22 is started, which drives the sprocket 19 to rotate through the transmission mechanism 23. The rotation of the sprocket 19 drives the chain 20 to rotate, and the chain 20 drives the slider 21 to slide in the slide groove 17. Then, the connecting block 10 and the connecting seat 211 drive the suspension device to move. When the driven friction disc 8 touches the active friction disc 16, the first motor 15 drives the active friction disc 16 to rotate. The active friction disc 16 drives the driven friction disc 8 through friction. The rotation of the first belt 6 drives the first pulley 5 to rotate, which in turn drives the first pulley 5 on the other side to rotate. The first pulley 5 then drives the meshing gear 4 to rotate, thereby causing the clamping block 3 to rotate the aluminum profile. After the spraying is completed, the second motor 22 reverses, and the suspension device returns via the chain 20, entering the baking room for a 200°C baking process for 15 minutes. After the baking is completed, it needs to return to the initial position. A crane is used to remove the connecting block 10 from the connecting seat 211 along with the aluminum profile and place it on the shelf. The suspension devices on both sides are then removed to complete the unloading. This device achieves automatic rotation of the aluminum profile to be sprayed, eliminating the need to change various angles to ensure uniform spraying. It is easy to link with a single-angle spraying machine to replace manual spraying of aluminum profiles, greatly improving spraying efficiency and consistency of spraying quality.
[0032] Limit switch 24, first motor 15, second motor 22 and controller are electrically connected. The controller can be a common PLC controller, such as Siemens S7-200+ series. It can operate continuously and automatically by setting the program, linking the spraying equipment and paint booth to complete the automated spraying process of aluminum profiles.
[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
