Description

Technical Field

[0001] This utility model relates to the field of scraper coating head installation and removal technology, and in particular to a scraper coating head disassembly and installation device. Background Technology

[0002] Various coatings are applied to the surface of automobiles to improve the service life and aesthetics of automotive components. The characteristics of the coating determine its protective effect. Most coated surfaces are coated with various paints. During the coating process, a doctor blade inside the coating machine is needed for application. The comma doctor blade is a commonly used coating technology. The design of the comma doctor blade is mainly used to control the coating thickness and uniformity. At the same time, the comma doctor blade also has orifices of multiple sizes, which can be adjusted to control the flow rate and pressure of the paint.

[0003] Most existing doctor blade coating head disassembly and installation devices are equipped with a single support structure. During use, the doctor blade is installed and supported by a single support structure. However, when the doctor blade coating head is coating the substrate, it usually works continuously. When the single support structure is installed or removed, the whole device needs to stop for a long time, which results in a longer interval between coating operations and a decrease in the effectiveness of the doctor blade coating head disassembly and installation device.

[0004] Therefore, to address the problem that existing doctor blade coating head disassembly and installation devices require a relatively long time to stop during the installation and removal of individual support structures, resulting in longer coating intervals and a decrease in the effectiveness of the device, a doctor blade coating head disassembly and installation device with a dual installation structure can be designed. Utility Model Content

[0005] To overcome the problem that existing doctor blade coating head disassembly and installation devices require the entire device to be stopped for a long time when a single support structure is installed or removed, resulting in a longer coating interval and a decrease in the effectiveness of the device.

A rotating plate is rotatably connected to the outer side of the connecting rod. Support frames are installed on the upper and lower ends of the movable frame. Mounting platforms are provided on the inner side of the support frames.

[0007] Preferably, the rotating frame is rotated by the lifting frame and the mounting block, the moving frame connecting rod drives the rotating plate to move, and the position of the moving frame is controlled by the fixed platform and the fixing bolts. The rotating plate is moved by the receiving groove to cooperate with the support frame to drive the mounting platform to rotate. At the same time, two coating heads are loaded by the upper and lower sets of mounting platforms respectively, thereby improving the overall installation efficiency.

[0008] Preferably, a hydraulic push rod is installed on the inner side of the support body, and a lifting frame is fixedly connected to the output end of the hydraulic push rod. The hydraulic push rod is used to drive the lifting frame to rise and fall, and a rotating rod is rotatably connected to the outer side of the support body.

[0009] Preferably, a telescopic rod is slidably connected to the upper end of the rotating rod, and a rotating platform is rotatably connected to the upper end of the telescopic rod. A first motor is installed on the outside of the rotating platform, and a power gear is fixedly connected to the output end of the first motor. The first motor is used to drive the power gear to rotate.

[0010] Preferably, a limiting block is fixed to the outer side of the mounting platform, and the mounting platform and the support frame are rotatably connected through the limiting block. A connecting block is fixed to one end of the mounting platform, and the connecting block is rotatably connected to the rotating plate.

[0013] Preferably, a comma scraper body is provided between the two limiting plates, and limiting strips are fixed to both ends of the comma scraper body. The connecting toothed ring and the comma scraper body are slidably connected through the limiting strips.

[0014] The beneficial effects of this utility model are:

[0015] The doctor blade coating head disassembly and installation device uses two sets of upper and lower mounting platforms to load two coating heads respectively. By rotating the frame through the lifting frame and mounting block, the two coating heads can be rotated to exchange positions during loading and unloading, thereby quickly changing the coating head that needs to be used and quickly restarting the coating process. At the same time, the two sets of moving frames and rotating plates can load and unload the coating heads separately, further reducing the impact on the coating work. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides an embodiment of a scraper coating head disassembly and installation device, including a support body 1; it also includes a lifting frame 3 and a rotating frame 9.

A receiving groove 12 is opened on the inner side of the fixed platform 11, and a movable frame 13 is slidably connected to the inner side of the receiving groove 12. Fixing bolts 14 are provided on the outer side of the movable frame 13, and a fixed bolt is fixedly connected to the outer side of the movable frame 13. A connecting rod 15 is rotatably connected to a rotating plate 16 on its outer side. Support frames 17 are installed at both the upper and lower ends of the movable frame 13. An installation platform 18 is provided on the inner side of the support frame 17. The rotating frame 9 is rotated by the lifting frame 3 and the installation block 10, and the connecting rod 15 of the movable frame 13 drives the rotating plate 16 to move. The position of the movable frame 13 is controlled by the fixed platform 11 and the fixed bolt 14. The rotating plate 16 is moved through the receiving groove 12 to cooperate with the support frame 17 to drive the installation platform 18 to rotate. At the same time, two coating heads are loaded on the upper and lower sets of installation platforms 18 respectively, thereby improving the overall installation efficiency.

[0024] Please see Figures 2-4In this embodiment, a hydraulic push rod 2 is installed on the inner side of the support body 1. A lifting frame 3 is fixedly connected to the output end of the hydraulic push rod 2. The hydraulic push rod 2 is used to drive the lifting frame 3 to rise and fall. A rotating rod 4 is rotatably connected to the outer side of the support body 1. The lifting frame 3 and the rotating frame 9 are driven to rise and fall by the hydraulic push rod 2, which facilitates normal loading and unloading of the coating head and reduces interference. A telescopic rod 5 is slidably connected to the upper end of the rotating rod 4. A rotating platform 6 is rotatably connected to the upper end of the telescopic rod 5. A first motor 7 is installed on the outer side of the rotating platform 6. A power gear 8 is fixedly connected to the output end of the first motor 7. The first motor 7 is used to drive the power gear 8 to rotate. The position of the rotating platform 6 is adjusted by the rotating rod 4 in conjunction with the telescopic rod 5, and the power gear 8 is driven to rotate by the first motor 7. A limiting block 19 is fixedly connected to the outer side of the mounting platform 18. The mounting platform 18 and the support frame 17 are rotatably connected by the limiting block 19. A connecting block 20 is fixedly connected to one side end of the mounting platform 18. The connecting block 20 is rotatably connected to the rotating plate 16. The mounting platform 18 is driven to rotate by the rotating plate 16 and the connecting block 20.

[0025] Please see Figures 3-5 In this embodiment, a second motor 21 is installed on the other end of the mounting platform 18. A threaded rod 22 is fixedly connected to the output end of the second motor 21. The second motor 21 is used to drive the threaded rod 22 to rotate. The outer side of the threaded rod 22 is threadedly connected to a limiting plate 23. The limiting plate 23 is slidably connected to the mounting platform 18. A connecting toothed ring 24 is rotatably connected to the inner side of the limiting plate 23. The connecting toothed ring 24 meshes with the power gear 8. The threaded rod 22 and the mounting platform 18 drive the limiting plate 23 to move, thereby driving the connecting toothed ring 24 to move. A comma scraper body 25 is provided between the two limiting plates 23. Limiting strips 26 are fixedly connected to both ends of the comma scraper body 25. The connecting toothed ring 24 and the comma scraper body 25 are slidably connected through the limiting strips 26. The connecting toothed ring 24 is connected to the limiting strips 26, thereby installing the comma scraper body 25. The power gear 8 drives the connecting toothed ring 24 and the comma scraper body 25 to rotate.

[0026] During installation, firstly, the moving frame 13 is moved by the connecting rod 15, which drives the rotating plate 16 to move. The position of the moving frame 13 is controlled by the fixed platform 11 and the fixing bolt 14. Then, the rotating plate 16 and the connecting block 20 drive the mounting platform 18 to rotate, thereby changing the tilt angle of the rotating plate 16 to align with the comma scraper body 25. Then, the second motor 21 is started to drive the threaded rod 22 to rotate. The threaded rod 22 and the mounting platform 18 drive the limiting plate 23 to move, thereby driving the connecting toothed ring 24 to move. Finally, the limiting strip 26 is connected to the connecting toothed ring 24 to install the comma scraper body 25.

[0027] In use, firstly, the hydraulic push rod 2 drives the lifting frame 3 and the rotating frame 9 to rise and fall, thereby moving the comma scraper body 25 into or out of the coating position. Next, the rotating rod 4, in conjunction with the telescopic rod 5, adjusts the position of the rotating table 6, and the first motor 7 drives the power gear 8 to rotate, thereby cooperating with the connecting gear ring 24 and the limiting strip 26 to rotate the comma scraper body 25. During replacement and unloading, the hydraulic push rod 2 drives the two comma scraper bodies 25 to rise, and the rotating frame 9 is rotated by the mounting block 10. Then, the rotating frame 9 drives the upper and lower mounting platforms 18 and the comma scraper body 25 to rotate. Finally, the above steps are repeated to replace and unload the comma scraper body 25, thereby quickly loading and unloading the comma scraper body 25 that needs to be coated.

[0028] Through the above steps, by setting up two sets of mounting platforms 18 to load two coating heads respectively, and by rotating the rotating frame 9 through the lifting frame 3 and mounting block 10, the two coating heads can be rotated to change positions during loading and unloading, thereby quickly replacing the coating head that needs to be worked and quickly restarting the coating process. At the same time, the two sets of moving frames 13 and rotating plates 16 can load and unload the coating heads separately, further reducing the impact on the coating work. This solves the problem that when using the existing doctor blade coating head disassembly and installation device, the entire device needs to stop for a long time during the loading and unloading of a single support structure, resulting in a long interval between coating operations and a decrease in the effectiveness of the doctor blade coating head disassembly and installation device.
