Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and more specifically, to a multi-coating spraying box. Background Technology

[0002] Spray coating is a coating method that uses a spray gun or atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the coating to the surface of the object. It can be divided into air spraying, airless spraying, and electrostatic spraying. Spray coating is a highly efficient production method suitable for both manual operations and automated industrial production. It has a wide range of applications, primarily in hardware, plastics, furniture, military, and shipbuilding industries, and is currently the most widely used coating method.

[0003] Existing multi-channel spraying equipment generally uses only one hose to deliver the spraying liquid into the conduits of multiple spray guns. When the hose is blocked, it affects the normal operation of multiple spray guns.

[0004] A search revealed that Chinese patent CN218360037U discloses a multi-channel synchronous spraying device. This utility model uses a paint tank to transport spraying liquid into hollow plates through a conveying pipe, and then sprays it out from an atomizing nozzle to synchronously spray workpieces conveyed by a suspension chain. Since multiple hollow plates are supplied with spraying liquid through multiple channels, even if one channel is blocked, the other channels can still carry out spraying work normally, ensuring work efficiency.

[0005] However, in actual use, the above-mentioned spraying device is cumbersome and time-consuming to change different paints when spraying different paints, and cannot switch paints in time to spray parts, which affects the spraying efficiency of parts. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-coating spray box to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A multi-coating spray box includes a working box with a multi-coating connection mechanism at its rear. The multi-coating connection mechanism includes three base frames. One side of each base frame is fixedly connected to the outside of the working box. Two positioning plates are fixedly connected to the outside of the base frames. An elastic baffle is fixedly connected to one side of each positioning plate. Two locking plates are hinged to one side of each base frame, with one side of each locking plate fixedly connected to one side of the elastic baffle. A guide rod is slidably connected to the bottom of each base frame. A first spring is installed on the outside of the guide rod, with its bottom fixedly connected to the inner wall of the base frame. A base plate is fixedly connected to the top of the guide rod. An anti-slip pad is fixedly connected to the upper surface of the base plate. A paint tank is installed on the top of the anti-slip pad, with its outer side slidably connected to the inner wall of the base frame. Three connecting frames are fixedly connected to the rear of the working box. A top cover is fixedly connected to the bottom of each connecting frame. A sealing ring is installed on the inner wall of each top cover. Each of the three top covers is connected to a material conveying pipe, with an atomizing nozzle installed at one end of each material conveying pipe.

[0009] By adopting the above technical solution, paint tanks can be quickly replaced and installed, and multiple paint tanks can be used to store different paints, thereby improving the efficiency of paint switching and paint tank replacement.

[0010] As a further description of the above technical solution: a door is hinged to the front of the work box, a slider is slidably connected to the inner wall of the door, a push rod is fixedly connected to the outer side of the slider, a placement frame is fixedly connected to one end of the push rod, a rotating block is threadedly connected to one side of the placement frame, a bracket is fixedly connected to the inner wall of the door, and a guide plate is fixedly connected to the top of the bracket.

[0011] By adopting the above technical solution, the spraying position of the parts can be controlled in real time by pushing the push rod, so as to avoid uneven coating.

[0012] As a further description of the above technical solution: a waste liquid collection mechanism is provided at the bottom of the working box. The waste liquid collection mechanism includes a first sieve plate, the outer side of which is fixedly connected to the bottom of the working box. A second sieve plate is provided at the bottom of the first sieve plate, the outer side of which is slidably connected to the inner wall of the working box. A plurality of guide columns are fixedly connected to the inner wall of the working box. A second spring is fixedly connected to the outer side of the guide columns. One end of the second spring is fixedly connected to one side of the second sieve plate. A collection box is slidably connected to the bottom of the working box, and one side of the collection box is engaged with the bottom of the second sieve plate.

[0013] By adopting the above technical solution: when the collection box is inserted, the connection between the first screen plate and the second screen plate remains connected, so that excess paint can fall into the inside of the collection box. When the collection box is pulled out, the first screen plate and the second screen plate close again to prevent paint from flowing around at the bottom of the working box.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] By setting up a multi-coating connection mechanism, compared with the existing technology, multiple coating tanks can be installed quickly, which facilitates the rapid replacement of used coating tanks. At the same time, different material delivery pipes and atomizing nozzles can be connected according to the spraying needs to spray parts, speeding up the operator's replacement of coating tanks and improving the spraying efficiency of parts.

[0016] By setting up a waste liquid collection mechanism, compared with the existing technology, the waste liquid after spraying can be collected, and the first and second screen plates can be staggered and sealed in time when the collection box is pulled out for cleaning, so as to prevent the paint from scattering everywhere and keep the work box clean for spraying.

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] This application discloses a multi-coating spray box, including a working box 1. A multi-coating connection mechanism is provided on the rear side of the working box 1. The multi-coating connection mechanism includes three base frames 2. One side of each base frame 2 is fixedly connected to the outside of the working box 1. Two positioning plates 3 are fixedly connected to the outside of each base frame 2. An elastic baffle 4 is fixedly connected to one side of each positioning plate 3. Two clamping plates 5 are hinged to one side of each base frame 2. One side of each clamping plate 5 is fixedly connected to one side of each elastic baffle 4. A guide rod 6 is slidably connected to the bottom of each base frame 2. A first spring 7 is provided on the outside of each guide rod 6. The bottom of the first spring 7 is fixedly connected to the inner wall of each base frame 2. A base plate 8 is fixedly connected to the top of each guide rod 6. An anti-slip pad 9 is fixedly connected to the upper surface of the base plate 8. A paint tank 10 is provided on the top of the anti-slip pad 9. The outside of the paint tank 10 is slidably connected to the inner wall of each base frame 2. Three connecting brackets 11 are fixedly connected to the rear side of the work box 1. A top cover 12 is fixedly connected to the bottom of the connecting bracket 11. A sealing ring 13 is installed on the inner wall of the top cover 12. The top of each of the three top covers 12 is connected to a conveying pipe 14. An atomizing nozzle 15 is installed at one end of the conveying pipe 14. Pulling the guide rod 6 will insert the paint can 10 into the interior of the base frame 2. Then, two elastic baffles 4 will push the corresponding clamping plate 5 to limit the outer side of the paint can 10, so that the paint can 10 is stably fixed inside the base frame 2. Then, the first spring 7 will push the bottom plate 8 and the anti-slip pad 9 to push the bottom of the paint can 10, so that the top of the paint can 10 is sealed with the sealing ring 13 inside the top cover 12. Then, the pump switch will be turned on, so that the paint is sprayed out through the conveying pipe 14 and the atomizing nozzle 15 to spray the parts.

[0028] Reference Figure 5 As shown, a door 16 is hinged to the front of the work box 1. A slider 17 is slidably connected to the inner wall of the door 16. A push rod 18 is fixedly connected to the outer side of the slider 17. A placement frame 19 is fixedly connected to one end of the push rod 18. A rotating block 20 is threadedly connected to one side of the placement frame 19. A bracket 21 is fixedly connected to the inner wall of the door 16. A guide plate 22 is fixedly connected to the top of the bracket 21. Rotating the rotating block 20 fixes the parts inside the placement frame 19. Then, pushing the push rod 18 causes it to move horizontally inside the work box 1 under the guidance of the guide plate 22, which facilitates the painting of the parts.

[0029] Reference Figure 7 and Figure 8As shown, a waste liquid collection mechanism is provided at the bottom of the working box 1. The waste liquid collection mechanism includes a first sieve plate 23, the outer side of which is fixedly connected to the bottom of the working box 1. A second sieve plate 24 is provided at the bottom of the first sieve plate 23, the outer side of which is slidably connected to the inner wall of the working box 1. Multiple guide posts 25 are fixedly connected to the inner wall of the working box 1, and a second spring 26 is fixedly connected to the outer side of the guide posts 25. One end of the second spring 26 is fixedly connected to one side of the second sieve plate 24. A collection box 27 is slidably connected to the bottom of the working box 1. One side of the collection box 27 is engaged with the bottom of the second sieve plate 24. Pushing the collection box 27 engages the bottom of the second sieve plate 24, causing the second sieve plate 24 to squeeze the multiple second springs 26, so that the openings of the multiple second sieve plates 24 overlap with the openings of the first sieve plate 23, allowing excess paint inside the working box 1 to fall into the collection box 27 through the first sieve plate 23 and the second sieve plate 24.

[0030] The working principle of this utility model is as follows: When spraying parts, first open the box door 16, place the parts inside the placement frame 19, rotate the rotating block 20 to fix the parts inside the placement frame 19, and then close the box door 16 again to allow the placement frame 19 to move the parts into the working box 1. Then, through the pump and the corresponding delivery pipe 14, the paint in the paint tank 10 is quickly fed into the atomizing nozzle 15. The atomizing nozzle 15 then sprays the parts fixed in the placement frame 19. When different paints need to be sprayed on the parts, the pump opens and closes different delivery pipes 14 and paint tanks 10, allowing different paints in different paint tanks 10 to be sprayed through the corresponding atomizing nozzles 15. After the paint inside the paint can 10 is used up, pull the guide rod 6 to squeeze the first spring 7, then remove the used paint can 10 from the inside of the base frame 2, and then squeeze the two clamping plates 5 again with the new paint can 10, and then put the paint can 10 into the inside of the base frame 2, so that the anti-slip pad 9 provides anti-slip support for the bottom of the paint can 10. Then, release the guide rod 6 and push the base plate 8 and the anti-slip pad 9 to push the top of the paint can 10 to fit and seal with the sealing ring 13 at the bottom of the top cover 12. At the same time, the corresponding two elastic baffles 4 push the clamping plates 5, so that the two clamping plates 5 rotate to fit and limit the outside of the paint can 10, so that the paint can 10 can remain stable inside the base frame 2.

[0031] During spraying, excess paint falls from the first screen plate 23 and the second screen plate 24 into the collection box 27. When the collection box 27 is pulled out from the bottom of the working box 1, the pushing force on the bottom of the second screen plate 24 is released on one side of the collection box 27, causing multiple second springs 26 to push the second screen plate 24 to move at the bottom of the working box 1. This causes multiple drainage holes of the first screen plate 23 and the second screen plate 24 to be arranged in an alternating pattern, allowing the solution that has not entered to remain inside the working box 1, thus preventing the solution from falling into the bottom of the working box 1 when there is no slider 17 to collect it.

[0032] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0033] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
