[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, such as Figures 1-3 As shown, a rotary spraying device includes a housing 1. A rotary conveying pipe 12 is disposed inside the housing 1. A second limiting ring 11 is integrally formed on the outer wall of the rotary conveying pipe 12. A fixing cylinder 9 is rotatably sleeved on the outer wall of the second limiting ring 11. The fixing cylinder 9 is fixedly connected to the housing 1. Two first conveying pipes 5 are symmetrically fixedly connected to the outer wall of the rotary conveying pipe 12. Multiple spray nozzles 8 are vertically and equidistantly installed on the side of each of the two first conveying pipes 5 that are close to each other. A mesh support frame 3 is installed inside the housing 1, located below the two first conveying pipes 5. A door panel 4 is rotatably connected to one end of the housing 1 via a rotating shaft. A locking assembly for locking and fixing the outer shell 1 and the door panel 4 is installed on the door panel 4. A connecting pipe 6 is provided at the top of the outer shell 1. The connecting pipe 6 passes through the interior of the outer shell 1 and is fixedly connected to the outer shell 1. A material conveying hose 7 is installed at the top of the connecting pipe 6. The end of the material conveying hose 7 away from the connecting pipe 6 is fixedly connected to the storage box. A first limiting ring 10 is integrally formed on the outer wall of the connecting pipe 6. The first limiting ring 10 is located inside the outer shell 1. The rotating material conveying pipe 12 is rotatably sleeved on the outer wall of the connecting pipe 6 and the first limiting ring 10. A drive mechanism is provided on the outer shell 1 to prevent the paint from polluting the surrounding environment.

[0035] The drive mechanism includes: a motor 201 mounted on the top of the housing 1, a transmission disk 202 fixedly connected to the output end of the motor 201, the transmission disk 202 being located inside the housing 1, a gear 203 fixedly connected to the bottom end of the transmission disk 202, a gear ring 204 meshing with the outer wall of the gear 203, the gear ring 204 being sleeved on the outer wall of the rotary conveying pipe 12, the gear ring 204 being fixedly connected to the rotary conveying pipe 12, and the gear ring 204 being located below the fixed cylinder 9;

[0036] The drive mechanism also includes: a positioning component disposed on the transmission disc 202;

[0037] The positioning component is a positioning plug 2012 located on the outside of the transmission disk 202. The positioning plug 2012 extends into the interior of the transmission disk 202. The outer wall of the positioning plug 2012 is hemispherical. Multiple positioning slots that match the outer wall of the positioning plug 2012 are equidistantly opened on the outer wall of the transmission disk 202.

[0038] A support assembly is provided on the outer casing 1;

[0039] In this embodiment, the workpiece is placed on the upper surface of the mesh support frame 3 and below the rotating conveyor pipe 12. Then, the door panel 4 is rotated around the pivot to block the opening of the outer shell 1. After that, the door panel 4 is locked and fixed by the locking assembly.

[0040] During this process, the limiting block of the positioning plug 2012 can be released by the drive mechanism. Then, the motor 201 is started to drive the transmission disk 202 to rotate. At this time, the gear 203, driven by the transmission disk 202, drives the gear ring 204 to rotate through meshing. At the same time, the drive mechanism can rotate and position the transmission disk 202.

[0041] Meanwhile, driven by the toothed ring 204, the rotating conveying pipe 12 rotates along the inner wall of the fixed cylinder 9 through the second limiting ring 11. At this time, the rotating conveying pipe 12 rotates along the outer wall of the connecting pipe 6 through the first limiting ring 10. At the same time, the two first conveying pipes 5, driven by the rotating conveying pipe 12, drive multiple nozzles 8 to move. At this time, the paint can be conveyed to the inner cavity of the nozzle 8 through the conveying hose 7. Thus, the nozzle 8 can spray the paint evenly onto the outer wall of the workpiece by spraying.

[0042] If the door panel 4 is not closed, the drive mechanism can rotate and lock the transmission plate 202 to prevent the rotating material conveying pipe 12 from rotating when the door panel 4 is not closed, thereby further reducing the pollution of the surrounding environment caused by the paint.

[0043] In one embodiment, such as Figure 3 As shown, the support assembly is used to support the positioning plug 2012;

[0044] The support assembly is a support plate 205 that is slidably sleeved on the outer wall of the positioning insert 2012, and the support plate 205 is fixedly connected to the outer shell 1;

[0045] A limit component is provided on the positioning plug 2012;

[0046] The limiting component includes: a limiting baffle 2011 fixedly connected to the side of the positioning block 2012 away from the transmission plate 202; a limiting slide rod 209 fixedly connected to the side of the limiting baffle 2011 away from the positioning block 2012; the limiting slide rod 209 and the limiting baffle 2011 are slidably connected to the support plate 205; through the cooperation of the support component and the limiting component, the positioning block 2012 can be limited to move.

[0047] A first reset component is provided on the limit slide bar 209, which is used to push the limit baffle 2011 to slide and reset.

[0048] In one embodiment, such as Figure 3As shown, the first reset component is a second spring 2010 sleeved on the outer wall of the limiting slide bar 209. One end of the second spring 2010 contacts the outer wall of the limiting baffle 2011, and the other end of the second spring 2010 contacts the inner wall of the support plate 205. The positioning block 2012 can be rotated and positioned by the second spring 2010 to rotate the transmission disk 202.

[0049] A movable component is provided on the support plate 205;

[0050] In one embodiment, such as Figures 1-3 As shown, the moving component includes: a limiting push rod 206 disposed at one end of the support plate 205, the limiting push rod 206 extending to the outside of the other end of the support plate 205, a connecting baffle 207 integrally formed on the outer wall of the limiting push rod 206, the connecting baffle 207 contacting one side of the outer wall of the limiting slide rod 209, the limiting push rod 206 and the connecting baffle 207 are both slidably connected to the support plate 205, and through the limiting push rod 206 and the connecting baffle 207, the positioning insert 2012 can be rotated and locked to the transmission disc 202 when the door panel 4 is in an unclosed state;

[0051] A second reset component is provided on the limit push rod 206, which is used to push the connecting baffle 207 to slide and reset.

[0052] In one embodiment, such as Figure 3 As shown, the second reset component is a first spring 208 sleeved on the outer wall of the limiting push rod 206. One end of the first spring 208 contacts the outer wall of the connecting baffle 207, and the other end of the first spring 208 contacts the inner wall of the support plate 205. The first spring 208 can push the connecting baffle 207 to automatically reset when the door panel 4 is opened.

[0053] The above embodiment discloses a rotary spraying device, wherein, during use, the workpiece is placed on the upper surface of the mesh support frame 3 and below the rotary conveying pipe 12, and then the door plate 4 is rotated around the pivot to block the opening of the outer shell 1, and then the door plate 4 is locked and fixed by the locking assembly.

[0054] During this process, under the pressure of the door panel 4, the limiting push rod 206 drives the connecting baffle 207 to slide along the inner wall of the support plate 205. At this time, the connecting baffle 207 separates from the outer wall of the limiting slide rod 209 by moving and compresses the first spring 208 to retract, thereby releasing the limiting obstruction of the limiting slide rod 209.

[0055] Then, the motor 201 is started to drive the transmission disk 202 to rotate. At this time, the gear 203, driven by the transmission disk 202, drives the gear ring 204 to rotate through meshing. At the same time, the positioning block 2012, under the pressure of the transmission disk 202, pushes the limiting slide rod 209 to slide along the inner wall of the support plate 205 through the limiting baffle 2011. At this time, the limiting baffle 2011 retracts by moving and pressing the second spring 2010. When the transmission disk 202 drives the next positioning slot to the port of the positioning block 2012, the second spring 2010 rebounds and pushes the limiting baffle 2011 to insert the positioning block 2012 into the interior of the transmission disk 202, thereby enabling the transmission disk 202 to be rotated and positioned.

[0056] Meanwhile, driven by the toothed ring 204, the rotating conveying pipe 12 rotates along the inner wall of the fixed cylinder 9 through the second limiting ring 11. At this time, the rotating conveying pipe 12 rotates along the outer wall of the connecting pipe 6 through the first limiting ring 10. At the same time, the two first conveying pipes 5, driven by the rotating conveying pipe 12, drive multiple nozzles 8 to move. At this time, the paint can be conveyed to the inner cavity of the nozzle 8 through the conveying hose 7. Thus, the nozzle 8 can spray the paint evenly onto the outer wall of the workpiece by spraying.

[0057] If the door panel 4 is not closed, the limit slide bar 209 cannot move due to the obstruction of the connecting baffle 207, thereby locking the transmission disc 202 to prevent the rotating conveyor pipe 12 from rotating when the door panel 4 is not closed, thus further reducing the pollution of the surrounding environment caused by the paint.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
