[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-7As shown, this utility model embodiment provides a turntable structure for a spray painting table, including a support frame 1, a driving device 2 on the top of the support frame 1, and a rotating material table 3 above the driving device 2. The rotating material table 3 is used at least for placing the workpiece during spray painting. A housing 5 is fixedly installed on the top of the support frame 1, and a lifting sleeve 6 is inserted into the inside of the housing 5. A transmission mechanism 4 is provided at the bottom of the support frame 1. The transmission mechanism 4 is used at least for driving the lifting sleeve 6 to move up and down inside the housing 5. Locking devices 7 are provided on both outer walls of the housing 5. The locking devices 7 are used at least for locking the transmission mechanism 4 after the lifting sleeve 6 is raised. A retaining ring 9 is provided on the top of the support frame 1 below the rotating material table 3. The rotating material table 3 rotates on top of the retaining ring 9. A scraper assembly 8 is provided between the lifting sleeve 6 and the retaining ring 9. The scraper assembly 8 is used at least for scraping the paint on the surface between the lifting sleeve 6 and the retaining ring 9.

[0028] In this embodiment, as Figure 1-3 As shown, it includes a support frame 1, which is welded from a steel structure. A drive device 2 is installed on the top of the support frame 1, and a rotating material table 3 is installed above the drive device 2. The rotating material table 3 is used at least for placing the workpiece during spraying. The movement of the drive device 2 can drive the rotating material table 3 to rotate. In the past, some used a motor to drive the gear to rotate, and the gear to drive the gear ring to rotate, thereby realizing the rotational movement of the rotating material table 3. Some workpieces are placed directly on the rotating material table 3, while others have a clamp installed on the rotating material table 3 to clamp and fix the workpiece.

[0029] In this embodiment, as Figure 5 As shown, a housing 5 is fixedly installed on the top of the support frame 1. A base plate 51 is provided on the outer wall of the bottom of the housing 5. The bottom of the retaining ring 9 is located on one side of the top of the base plate 51, thereby forming a cavity structure for collecting paint between the housing 5, the base plate 51, the retaining ring 9, and the lifting sleeve 6. The base plate 51 is fixed on the outer wall of the top of the support frame 1. Slide grooves 52 are provided on both outer walls of the housing 5. The connecting shaft 63 is slidably inserted into the inside of the slide groove 52. A self-closing brush structure can be provided inside the slide groove 52, so that after the connecting shaft 63 is raised to the top, the inside of the slide groove 52 is sealed, or it can be opened directly. Since the slide groove 52 is relatively narrow, there will not be too much paint overflowing.

[0030] Specifically, such as Figure 3 and 5 As shown, a slag discharge port 53 is provided on one side of the bottom of the base plate 51, and a discharge pipe 54 corresponding to the slag discharge port 53 is fixedly provided at the bottom of the base plate 51. The coating on the surface of the outer shell 5, the lifting sleeve 6 and the retaining ring 9 can be scraped off by the scraper assembly 8 and discharged downward through the slag discharge port 53 and the discharge pipe 54 to achieve the collection of the coating.

[0031] In this embodiment, as Figure 3 and 6 As shown, a lifting sleeve 6 is inserted inside the outer casing 5. The bottom of the lifting sleeve 6 is equipped with a scraper structure, which can be achieved by chamfering. When the lifting sleeve 6 descends, it can scrape the paint inside the outer casing 5 downwards. The top of the lifting sleeve 6 is equipped with a tapered end 61, which is bent inwards to better block the paint. A guide rail 62 is provided on the inner wall of the lifting sleeve 6. The sliding groove 82 on one side of the scraper 81 is engaged with the guide rail 62 to guide the scraper assembly 8. Connecting shafts 63 are fixedly installed on both outer walls of the lifting sleeve 6. The top of the lifting rod 46 of the transmission mechanism 4 is connected to the connecting shaft 63, thereby driving the connecting shaft 63 to move up and down.

[0032] In this embodiment, as Figure 4 As shown, a transmission mechanism 4 is provided at the bottom of the support frame 1. The transmission mechanism 4 is used to drive the lifting sleeve 6 to move up and down inside the outer shell 5. The transmission mechanism 4 includes a forward and reverse motor 41 fixed inside the support frame 1, and a transmission rod 44 is provided on the output shaft at both ends of the forward and reverse motor 41. Bearing seats 42 fixed on the support frame 1 are sleeved on both sides of the transmission rod 44. A brake 43 is provided on the outside of the transmission rod 44. After the forward and reverse motor 41 drives the transmission rod 44 to rotate, the brake 43 is used to brake the transmission rod 44, ensuring the stability of the transmission mechanism 4 when it stops. Both ends of the moving rod 44 are fixedly installed with swing rods 45. The ends of the swing rods 45 are provided with rotating joints 47, and the ends of the swing rods 45 are installed with lifting rods 46 through the rotating joints 47. When the workpiece is placed above the rotating table 3, the operator starts the forward and reverse motor 41, which can drive the transmission rod 44 to rotate inside the bearing seat 42. The ends of the transmission rod 44 drive the swing rods 45 to rotate synchronously. The rotating joints 47 can drive the lifting rods 46 to move. The lifting rods 46 drive the connecting shaft 63 to move linearly inside the slide groove 52, realizing the lifting and lowering movement of the lifting sleeve 6 inside the outer shell 5.

[0033] In this embodiment, as Figure 1 As shown, locking devices 7 are provided on both outer walls of the outer casing 5. The locking devices 7 are used to lock the transmission mechanism 4 after the lifting sleeve 6 is raised. The locking devices 7 can be electromagnetic structures with extension and retraction movements. When the transmission mechanism 4 drives the connecting shaft 63 to rise to the top inside the slide groove 52, the locking devices 7 are activated, so that the pin extends and is located below the connecting shaft 63, thereby limiting the connecting shaft 63 inside the slide groove 52 and ensuring the stability of the lifting sleeve 6 inside the outer casing 5.

[0034] In this embodiment, as Figure 3As shown, the top of the support frame 1 is provided with a retaining ring 9 located below the rotating material table 3. The rotating material table 3 rotates on top of the retaining ring 9. The bottom of the rotating material table 3 is provided with a groove 31. The top of the retaining ring 9 is slidably inserted into the inside of the groove 31. The outer surface of the retaining ring 9 is flush with the outer surface of the rotating material table 3. The top of the retaining ring 9 is inserted into the inside of the groove 31, which improves the sealing of the connection between the rotating material table 3 and the retaining ring 9 and improves the blocking effect of the retaining ring 9 on the coating.

[0035] In this embodiment, as Figure 3 and 7 As shown, a scraper assembly 8 is provided between the lifting sleeve 6 and the retaining ring 9. The scraper assembly 8 is used at least to scrape off the paint on the surface between the lifting sleeve 6 and the retaining ring 9. The scraper assembly 8 includes a first scraper 81 and a second scraper 84 distributed on both sides. The first scraper 81 is in close contact with the inner wall of the outer casing 5, and the second scraper 84 is in close contact with the outer wall of the lifting sleeve 6. A sliding groove 82 distributed vertically is provided on one side of the first scraper 81. A connecting frame 83 is provided at the top of the first scraper 81 and the second scraper 84, and a handle 85 is installed on the top of the connecting frame 83. After the workpiece is sprayed, the operator first uses the transmission mechanism 4 to lift the lifting sleeve. 6 is lowered inside the outer casing 5, and then the operator holds the handle 85, which can drive the first scraper 81 and the second scraper 84 to rotate between the lifting sleeve 6 and the retaining ring 9 through the connecting frame 83. The first scraper 81 and the second scraper 84 are used to scrape off the paint on the surface of the lifting sleeve 6 and the retaining ring 9. When the first scraper 81 and the second scraper 84 move above the slag discharge port 53, the excess paint will fall into the slag discharge port 53 and the discharge pipe 54 and be discharged, thus collecting the paint.

[0036] Working principle: When the operator sprays the workpiece, the workpiece is placed above the rotating table 3. The drive device 2 can drive the rotating table 3 to rotate, so as to achieve uniform spraying on the surface of the workpiece (the above spraying operation is also a commonly used structure).

[0037] When spraying the workpiece, excess paint will spread or fall onto the drive device 2 below the rotating table 3, affecting the normal movement of the drive device 2. Therefore, a retaining ring 9 is installed below the rotating table 3 to block the drive device 2 and prevent excess paint from falling onto the drive device 2.

[0038] Meanwhile, the outer shell 5 and the lifting sleeve 6 set outside the retaining ring 9 can be used by the operator to start the transmission mechanism 4 after the workpiece is placed above the rotating table 3. The transmission mechanism 4 drives the lifting sleeve 6 to rise inside the outer shell 5, and the outer shell 5 and the lifting sleeve 6 can block the spread of excess paint.

[0039] After the workpiece is coated, the operator uses the transmission mechanism 4 to drive the lifting sleeve 6 to descend inside the outer shell 5. Using the scraper structure at the bottom of the lifting sleeve 6, the paint on the inner wall of the outer shell 5 can be scraped downwards. After the lifting sleeve 6 has completely descended, the operator can use the scraper assembly 8 to rotate between the lifting sleeve 6 and the retaining ring 9 to scrape off the paint on the surface of the retaining ring 9 and the lifting sleeve 6. Excess paint is collected through the slag discharge port 53 and the material discharge pipe 54 to ensure a clean spraying environment.
