[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] In one embodiment, Figure 1-Figure 7 As shown, a paint spraying device for fire-fighting pipe fittings comprises a base 1, a movable groove 11 is opened at the upper end of the base 1, a fixing structure 3 for fixing the pipe fitting is arranged inside the movable groove 11, a paint spraying bin 2 is fixedly installed at the middle part of the upper end of the base 1, a sealing door 22 is hingedly installed at the front end of the paint spraying bin 2, a door handle 221 is arranged at the front end of the sealing door 22, a paint bucket 4 and a paint spraying structure 8 are installed at the upper end of the paint spraying bin 2, the paint spraying structure 8 is located on the right side of the paint bucket 4, a feeding pipe 41 is fixed at the upper end of the paint bucket 4, a cover plate 42 is arranged at the upper end of the feeding pipe 41, a fixed cover 43 is fixed at the top of the left end of the paint bucket 4, and the bottom end of the fixed cover 43 is fixedly connected to the mounting ring 45 through a connecting rod 44, a stirring structure 5 for stirring the raw materials inside the paint bucket 4 is arranged inside the paint bucket 4, a rotating structure 6 for driving the pipe fitting to rotate is arranged on the paint spraying bin 2 and the left end of the paint bucket 4, and a reciprocating structure 7 for adjusting the position of the paint spraying structure 8 is arranged inside the paint spraying bin 2.
[0029] In this embodiment, first, the pipe fittings to be painted are placed inside the paint spraying bin 2, and then the pipe fittings are firmly fixed by the fixing structure 3 to ensure that the pipe fittings will not move during the painting process. Next, the sealing door 22 at the front end of the paint spraying bin 2 is closed, and the paint to be sprayed is prepared in the paint bucket 4. The paint can be added through the feed pipe 41, and the stirring structure 5 inside the paint bucket 4 will start working to ensure that the paint is mixed evenly to avoid precipitation or stratification. Then, the pipe fittings are driven to rotate during the painting process by the rotating structure 6. In this way, the surface of the pipe fittings can be evenly sprayed with paint, thereby improving the quality and efficiency of the painting. The paint spraying structure 8 is started to perform the painting operation. The paint is transported from the paint bucket 4 to the paint spraying structure 8, and then evenly sprayed onto the rotating pipe fittings.
[0030] In an optional embodiment, the fixed structure 3 includes a bidirectional moving component 30 and a clamp 31, the bidirectional moving component 30 includes a rotating motor 301, the rotating motor 301 is installed at the left end of the base 1, the output end of the rotating motor 301 extends to the inside of the moving groove 11 and is fixedly connected to a bidirectional screw 302, both ends of the bidirectional screw 302 are threadedly connected to a moving block 303, the two moving blocks 303 are symmetrically distributed at the left and right ends of the paint spraying tank 2, the left and right ends of the paint spraying tank 2 are rotatably installed with a rotating block 21, one end of the rotating block 21 is penetrated and opened with a rectangular opening 211, the moving block 303 is slidably installed inside the moving groove 11, a support block 304 is fixed at the upper end of the moving block 303, a fixed ring 305 is fixed at the upper end of the support block 304, and a clamp 31 is rotatably installed inside the fixed ring 305.
[0031] It should be noted that the fixing structure 3 realizes a stable clamping of the pipe fitting through the cooperation of the bidirectional moving assembly 30 and the clamp 31. The rotating motor 301 drives the bidirectional screw 302 to rotate. Since the threads at both ends of the bidirectional screw 302 have opposite directions, the two moving blocks 303 move relatively in the moving groove 11, and then drive the clamp 31 to approach the pipe fitting and clamp it through the support block 304 and the fixing ring 305.
[0032] In an optional embodiment, the clamp 31 includes a rotating ball block 311, which is rotatably connected to the bidirectional movable assembly 30. One end of the rotating ball block 311 close to the paint spray tank 2 is fixedly connected to a rectangular rod 312. The outer wall of the rectangular rod 312 is slidably connected to the inner wall of the rectangular opening 211. The other end of the rectangular rod 312 extends to the interior of the paint spray tank 2 and is fixedly connected to a fixed cylinder 313. The opposite ends of the two fixed cylinders 313 are both conical.
[0033] It should be noted that the design of the rotating round block 311 and the rectangular rod 312 of the clamp 31 not only ensures the stable movement of the clamp 31, but also enhances the stability and flexibility of the clamping through the sliding of the rectangular rod 312 in the rectangular opening 211. The opposite end of the fixed cylinder 313 is designed to be conical, which helps to better adapt to pipes of different diameters and improve the adaptability and firmness of the clamping.
[0034] In an optional embodiment, the stirring structure 5 includes a driving motor 501, which is installed inside the mounting ring 45. The output end of the driving motor 501 is fixedly connected to a driving rod 502. A rotating structure 6 is provided on the outer wall of the driving rod 502. The other end of the driving rod 502 extends into the paint bucket 4. A connecting plate 505 is fixed to the end of the driving rod 502 away from the driving motor 501. Scrapers 504 are symmetrically fixed on both sides of the connecting plate 505 close to one end of the driving rod 502. The connecting plate 505 and the scraper 504 are in contact with the inner wall of the paint bucket 4. A plurality of stirring rods 503 are equidistantly fixed to the outer wall of the driving rod 502.
[0035] It should be noted that the stirring structure 5 drives the driving rod 502 to rotate through the driving motor 501, thereby driving the connecting plate 505, the scraper 504 and the stirring rod 503 to rotate together. This design ensures that the paint in the paint bucket 4 can be fully stirred and mixed, avoiding the precipitation and stratification of the paint. The design of the connecting plate 505 and the scraper 504 also helps to scrape off the residual paint on the inner wall of the paint bucket 4, further improving the utilization rate and mixing effect of the paint.
[0036] In an optional embodiment, the rotating structure 6 includes a driving wheel 601, a transmission belt 602 and a driven wheel 603, the driving wheel 601 is fixedly mounted on the outer wall of the driving rod 502, the driving wheel 601 is connected to the driven wheel 603 through the transmission belt 602, and the driven wheel 603 is fixedly mounted on the outer wall of the rotating block 21 at the left end of the paint spraying chamber 2.
[0037] It should be noted that the rotating structure 6 realizes the rotation of the pipe during the painting process by utilizing the transmission relationship between the driving wheel 601, the transmission belt 602 and the driven wheel 603. The driving wheel 601 rotates with the driving rod 502 and is also a part of the stirring structure 5, and transmits power to the driven wheel 603 through the transmission belt 602, thereby driving the rotating block 21 at the left end of the paint spraying chamber 2 to rotate, thereby driving the left rectangular rod 312 to rotate through the rectangular opening 211 opened by the rotating block 21, and finally driving the pipe to rotate through the fixed cylinder 313. This design not only simplifies the transmission mechanism, but also improves the stability and efficiency of the transmission.
[0038] In an optional embodiment, the reciprocating structure 7 includes a main gear 701, which is fixedly mounted on the outer wall of the rotating block 21 at the right end of the paint spraying tank 2, and the main gear 701 is meshedly connected to the slave gear 702. The end of the slave gear 702 close to the paint spraying tank 2 is fixedly connected to the reciprocating screw rod 703, and the reciprocating screw rod 703 is rotatably mounted inside the paint spraying tank 2. A reciprocating paint spraying block 804 that can reciprocate along the reciprocating screw rod 703 is sleeved on the reciprocating screw rod 703, and the reciprocating paint spraying block 804 is connected to the paint spraying structure 8 located at the upper end of the paint spraying tank 2. A guide rod 704 is fixedly mounted inside the paint spraying tank 2, and the outer wall of the guide rod 704 is slidably connected to the guide block 705, and the guide block 705 is fixedly connected to the reciprocating paint spraying block 804.
[0039] It should be noted that the rotating structure 6 drives the pipe to rotate, and the pipe drives the right clamp 31 to rotate, thereby driving the right end rotating block 21 of the paint spraying tank 2 to rotate, and the reciprocating structure 7 realizes the reciprocating movement of the reciprocating paint spraying block 804 inside the paint spraying tank 2 through the meshing relationship between the main gear 701 and the slave gear 702, and the rotation of the reciprocating screw 703. This design enables the paint spraying part 81 to move with the movement of the reciprocating paint spraying block 804, thereby achieving uniform paint spraying on the surface of the pipe. The design of the guide rod 704 and the guide block 705 ensures the stability and accuracy of the reciprocating paint spraying block 804 during movement.
[0040] In an optional embodiment, the paint spraying structure 8 includes a paint pump 802, which is installed at the upper end of the paint spraying bin 2. The liquid inlet of the paint pump 802 is connected to the interior of the paint bucket 4 through a connecting pipe 801. The liquid outlet of the paint pump 802 is connected to a spring tube 803. A valve 805 is provided at the connection between the paint pump 802 and the spring tube 803. The other end of the spring tube 803 is connected to a reciprocating paint spraying block 804, and a paint spraying part 81 is fixedly installed at the lower end of the reciprocating paint spraying block 804.
[0041] It should be noted that the paint spraying structure 8 extracts the paint from the paint bucket 4 through the paint pump 802, and delivers it to the reciprocating paint spraying block 804 through the spring tube 803. The design of the spring tube 803 has certain flexibility and elasticity, which can adapt to the position change of the reciprocating paint spraying block 804 during the movement. The setting of the valve 805 is convenient for controlling the delivery and stop of the paint, ensuring the smooth progress of the paint spraying operation. The paint spraying part 81 moves with the movement of the reciprocating paint spraying block 804, and the paint is evenly sprayed on the rotating pipe.
[0042] In an optional embodiment, the paint spraying part 81 includes a curved plate 812, which is located directly below the reciprocating paint spraying block 804. A paint sprayer nozzle 813 is fixed to the inner wall of the curved plate 812. A paint tube 811 is fixed and connected between the liquid outlet end of the reciprocating paint spraying block 804 and the paint sprayer nozzle 813. A collecting component 814 is provided on the inner wall of the rear end of the curved plate 812.
[0043] It should be noted that the collecting component 814 is arranged on the rear end inner wall of the arc plate 812, and its main function is to collect and recycle the excess paint or splashed paint drops generated during the painting process. The collecting component 814 can reduce the waste of paint and also help keep the paint spraying chamber 2 clean and tidy.
[0044] In an optional embodiment, the collecting component 814 includes an adjusting tube 8141, the adjusting tube 8141 is fixedly installed on the outer wall of the rear end of the arc plate 812, a return spring 8142 is installed inside the adjusting tube 8141, a sliding block 8143 is slidably installed inside the adjusting tube 8141, the sliding block 8143 is fixedly connected to the bottom of the adjusting tube 8141 through the return spring 8142, the sliding block 8143 extends from one end of the adjusting tube 8141 to the inside of the arc plate 812 and is fixedly connected to a smoothing block 8144, a filter screen 8145 is arranged on the top of one end of the smoothing block 8144 away from the sliding block 8143, and the interior of the smoothing block 8144 is connected to the interior of the collecting box 8147 through a spring paint drain tube 8146.
[0045] It should be noted that when the sliding block 8143 is subjected to an external force (for example, when the smoothing block 8144 contacts the surface of the pipe), the return spring 8142 will be compressed. When the external force disappears, the return spring 8142 will release energy to push the sliding block 8143 and the smoothing block 8144 back to the initial position. The smoothing block 8144 is used to smooth the paint on the surface of the pipe to ensure that the paint is evenly distributed and reduce the waste and dripping of the paint, so that the excess paint is smoothed and filtered through the filter 8145, and then discharged into the collection box 8147 through the spring paint discharge pipe 8146.
[0046] The above embodiment discloses a paint spraying device for fire-fighting pipe fittings, wherein the pipe fittings to be painted are placed inside the paint spraying cabin 2 .
[0047] The rotating motor 301 in the bidirectional moving assembly 30 is started, and the rotating motor 301 drives the bidirectional screw 302 to rotate, so that the two moving blocks 303 move toward the middle in the moving groove 11, and then drives the support block 304 and the fixing ring 305 to move, until the clamp 31 (connected to the moving block 303 through the rotating round block 311 and the rectangular rod 312) firmly clamps and fixes the pipe. At this time, the rectangular rod 312 slides in the rectangular opening 211 to ensure the stability and mobility of the clamp 31.
[0048] Close the sealing door 22 at the front end of the paint spraying cabin 2.
[0049] Open the cover plate 42 at the upper end of the feed pipe 41 , pour the paint into the paint bucket 4 , and then close the cover plate 42 .
[0050] The driving motor 501 in the stirring structure 5 is started, and the driving motor 501 drives the driving rod 502 to rotate, and then drives the connecting plate 505, the scraper 504 and the stirring rod 503 to rotate, so as to ensure that the paint in the paint bucket 4 is evenly mixed.
[0051] The driving wheel 601 rotates with the driving rod 502, and the driving wheel 601 drives the driven wheel 603 to rotate through the transmission belt 602, thereby driving the rotating block 21 at the left end of the paint spraying chamber 2 to rotate, thereby driving the left rectangular rod 312 to rotate through the rectangular opening 211 opened by the rotating block 21, and finally driving the pipe fitting to rotate through the fixed cylinder 313.
[0052] The rotation of the pipe member drives the right clamp 31 to rotate, thereby driving the rotating block 21 at the right end of the paint spraying tank 2 to rotate, and the main gear 701 rotates with the rotating block 21 at the right end of the paint spraying tank 2. The main gear 701 drives the rotation of the slave gear 702 and the reciprocating screw rod 703 through meshing connection. The rotation of the reciprocating screw rod 703 causes the reciprocating paint spraying block 804 (sliding on the guide rod 704 through the guide block 705) to reciprocate inside the paint spraying tank 2.
[0053] Open the valve 805 and start the paint pump 802 in the paint spraying structure 8 at the same time. The paint pump 802 draws paint from the paint bucket 4 through the connecting pipe 801 and transports it to the reciprocating paint spraying block 804 through the spring tube 803. The paint spraying part 81 (including the arc plate 812, the paint spraying machine nozzle 813, etc.) at the lower end of the reciprocating paint spraying block 804 moves with the movement of the reciprocating paint spraying block 804, and the paint is evenly sprayed onto the rotating pipe.
[0054] The collecting component 814 starts to work, and the smoothing block 8144 clings to the outer wall of the pipe under the action of the return spring 8142, smoothes the excess paint and filters it through the filter 8145, and then discharges it into the collecting box 8147 through the spring paint discharge pipe 8146.
[0055] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
