A support plate is fixedly connected to the upper end of the screw. A limit shaft is fixedly connected to the middle of the left side of the support plate. Two limit brackets are fixedly connected to the bottom left side of the housing, and the limit shaft is slidably connected to the limit brackets.

[0009] Feed pipes are fixedly connected to the middle of the left and right sides of the box, and pipe valves are fixedly installed on the feed pipes. Semi-circular spray frames are set on the left and right sides inside the box, and the feed pipes are fixedly connected to the semi-circular spray frames. Several spray holes are opened on the inner side of the semi-circular spray frames.

[0010] As a preferred technical solution of the metal workpiece coating spraying device of this utility model, a transparent window is fixedly connected to the middle position of the box cover.

[0011] As a preferred technical solution of the metal workpiece coating spraying device of this utility model, a protruding strip is fixedly connected to the middle position of the left side of the box cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a box-type structure. In use, the metal workpiece to be coated is placed on a support plate inside the box, and then the box cover is closed. The forward and reverse motors are then started. Through the coordinated arrangement of gears, internal threaded sleeves, limit rings, gear rings, and screws, as well as the guiding and limiting functions of the limit shaft and limit frame, the metal workpiece on the support plate can reciprocate up and down. Simultaneously, an external liquid pump feeds paint into the semi-circular spray frame via a feed pipe, and the paint is evenly sprayed out through several nozzles on the two semi-circular spray frames, thus achieving coating treatment on the surface of the reciprocating metal workpiece. This technical solution makes coating treatment on the surface of metal workpieces more labor-saving, convenient, efficient, and produces uniform and effective results. Furthermore, since the metal workpiece is coated within a closed box, paint is less likely to splash, which is beneficial to the health of workers, resulting in better overall performance.

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. Example

[0029] Please see Figure 1-8 The present invention provides the following technical solution: a metal workpiece coating spraying device, including a box body 1, a box cover 3 provided at the upper end of the box body 1, the right side of the box cover 3 being rotatably connected to the box body 1 through two rotating shafts 2, a transparent window 4 being fixedly connected at the middle position of the box cover 3, and a protruding strip 5 being fixedly connected at the middle position of the left side of the box cover 3. The box cover 3 is used to seal the upper opening of the box body 1, and the rotating shafts 2 enable the box cover 3 to be easily flipped open and closed. The transparent window 4 allows for observation of the spraying status of the metal workpiece 28 inside the box body 1 or the cleaning status inside the box body 1 without opening the box. The protruding strip 5 allows the box cover 3 to be lifted open and flipped down.

[0030] Support legs 6 are fixedly connected to the bottom of all four sides of the box 1. Support plates 7 are fixedly connected to the bottom of the support legs 6. Support pads 8 are fixedly connected to the bottom of the support plates 7. The support pads 8 are rubber components. The support legs 6 are used to support the bottom of the box 1. The support plates 7 can further increase the contact area between the bottom of the support legs 6 and the ground, making the support more stable. The support pads 8 can make the support plates 7 have anti-slip contact with the ground, which is more conducive to the anti-slip and stable placement of the device.

[0031] Two mounting brackets 9 are fixedly connected between the two support legs 6 on the left side. A forward and reverse motor 10 is fixedly installed on the right side of the mounting bracket 9. A gear 11 is fixedly connected to the output end of the forward and reverse motor 10. An opening 12 is opened in the middle of the bottom end of the housing 1. An internal threaded sleeve 13 is provided inside the opening 12. A limit ring 15 is fixedly connected around the upper end of the internal threaded sleeve 13. A limit groove 14 is opened inside the opening 12, and the limit ring 15 is rotatably connected to the limit groove 14. A gear ring 16 is fixedly connected around the bottom end of the internal threaded sleeve 13, and the gear 11 is meshed with the gear ring 16. A screw 17 is screwed into the internal threaded sleeve 13. A support plate 18 is fixedly connected to the upper end of the screw 17. A limit shaft 19 is fixedly connected to the middle of the left side of the support plate 18. Two limit brackets 20 are fixedly connected to the bottom left side of the inside of the housing 1, and the limit shaft 19 is connected to the limit... The mounting frame 20 is slidably connected. In use, the forward and reverse motor 10 drives the gear 11 to rotate. The rotating gear 11 further drives the gear ring 16, the internal threaded sleeve 13, and the limiting ring 15 to rotate as a whole. The rotation of the limiting ring 15 in the limiting groove 14 allows the gear ring 16, the internal threaded sleeve 13, and the limiting ring 15 to rotate in a fixed position. The rotation of the internal threaded sleeve 13 in the fixed position can further drive the screw 17 to move downward, thereby driving the support plate 18 and the metal workpiece 28 on the support plate 18 to move downward. The limiting shaft 19 slides relative to the limiting frame 20 for vertical guidance and limitation. The forward and reverse rotation of the forward and reverse motor 10 can drive the support plate 18 and the metal workpiece 28 on the support plate 18 to move up and down reciprocally, so that the surface of the metal workpiece 28 can be uniformly sprayed through the two semi-circular spray frames 23.

[0032] Feed pipes 21 are fixedly connected to the middle of the left and right sides of the housing 1. A pipe valve 22 is fixedly installed on the feed pipe 21. Semi-circular spray frames 23 are set on the left and right sides inside the housing 1, and the feed pipes 21 are fixedly connected to the semi-circular spray frames 23. Several spray holes are opened on the inner side of the semi-circular spray frames 23. The semi-circular spray frames 23 are hollow inside and closed at both ends. The feed pipes 21 are used to connect the semi-circular spray frames 23 to the external paint storage device. The pipe valves 22 are used for manual opening and closing of the feed pipes 21.

[0033] In this embodiment: The present invention has a box-type structure. In use, the metal workpiece 28 to be sprayed is placed on the support plate 18 inside the box 1, and then the box cover 3 is closed. Then, the forward and reverse motor 10 can be started. Through the setting and cooperation of gear 11, internal thread sleeve 13, limit ring 15, gear ring 16 and screw 17, as well as the guiding and limiting of limit shaft 19 and limit frame 20, the metal workpiece 28 on the support plate 18 can be moved up and down reciprocally. At the same time, the paint is input into the semi-circular spray frame 23 by the external liquid pump through the feed pipe 21, and is evenly sprayed out through several spray holes on the two semi-circular spray frames 23 to achieve the spraying treatment of the surface of the metal workpiece 28 moving up and down reciprocally. Through the above technical solution, the spraying treatment of the paint on the surface of the metal workpiece 28 is more labor-saving and convenient, with higher efficiency, and the spraying is uniform and the effect is better. In addition, the metal workpiece 28 is sprayed in the closed box 1, and the paint is not easy to splash, which is beneficial to the health protection of the workers. The overall use is better.

[0034] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a support ring 24 is fixedly connected to the middle of the bottom of the box 1. A sealing gasket 25 is fixedly connected to the upper end of the support ring 24. The sealing gasket 25 is a rubber component. The support plate 18 is driven to move down by the forward and reverse motor 10, and the support plate 18 is pressed and contacted with the sealing gasket 25 on the support ring 24, which can prevent water leakage at the opening 12 when the box 1 is filled with water.

[0035] A drain pipe 26 is fixedly connected to the bottom right side of the box 1. A pipe cover 27 is screwed onto the right end of the drain pipe 26. The pipe cover 27 is a rubber component. The drain pipe 26 is used to discharge the cleaning wastewater inside the box 1, and the pipe cover 27 is used to seal the drain pipe 26.

[0036] In this embodiment: the design of the box body 1 structure, the design of the drain pipe 26 and the pipe cover 27, and the further design of the support ring 24 and the sealing gasket 25 make it possible to soak the inside of the box body 1 after use by adding cleaning water and an appropriate amount of paint solvent. This can effectively remove the residue inside the box body 1, and then the sewage can be discharged through the drain pipe 26 for cleaning of the inside of the box body 1. Overall, the use is better.

[0037] The usage process and working principle of this utility model are as follows: When using it, the ends of the two feed pipes 21 need to be connected to the feed hose of the external liquid storage pump, and the pipe valve 22 needs to be opened. Then, the forward and reverse motors 10 are electrically connected to the external power supply.

[0038] In use, the box cover 3 is lifted by the protruding strip 5, and the box cover 3 is opened by flipping upwards via the rotating shaft 2. Then, the metal workpiece 28 to be sprayed is placed on the support plate 18 inside the box body 1, and the box cover 3 is closed. Then, the forward and reverse motor 10 is started, which drives the gear 11 to rotate. The rotating gear 11 further drives the gear ring 16, the internal threaded sleeve 13, and the limiting ring 15 to rotate as a whole. The rotation of the limiting ring 15 in the limiting groove 14 allows the gear ring 16, the internal threaded sleeve 13, and the limiting ring 15 to rotate in a fixed position. By rotating the internal threaded sleeve 13 in the fixed position, the screw 17 can be moved downwards, thereby driving the support plate 18 and the metal workpiece 28 on the support plate 18 to move downwards. The limiting shaft 19 slides relative to the limiting frame 20 for vertical guidance. The limit switch is used so that when the forward and reverse motor 10 drives the gear 11 to rotate a certain number of times, it rotates in the opposite direction to drive the gear 11 to rotate, thereby driving the support plate 18 and the metal workpiece 28 on the support plate 18 to move upward. This achieves the up-and-down reciprocating movement of the metal workpiece 28 on the support plate 18. Then, the external liquid storage pump is started, and the paint is input into the semi-circular spray frame 23 through the feed pipe 21. The paint is then evenly sprayed out through several spray holes on the two semi-circular spray frames 23 to achieve the spraying treatment of the surface of the metal workpiece 28 that moves up and down. Through the above technical solution, the spraying treatment of the paint on the surface of the metal workpiece 28 is more labor-saving and convenient, with higher efficiency, and the spraying is uniform and the effect is better. In addition, the metal workpiece 28 is sprayed in the closed box 1, and the paint is not easy to splash, which is beneficial to the health protection of the workers.

[0039] After the spraying is completed, turn off the external liquid pump and the forward and reverse motors 10, then open the box cover 3 and take out the metal workpiece 28 that has been sprayed on the support plate 18 inside the box 1.

[0040] In the future, the forward and reverse motor 10 can be started to drive the support plate 18 to move down and make the support plate 18 press against the sealing gasket 25 on the support ring 24 to prevent water leakage at the opening 12 when the tank 1 is filled with water. Then, the feed pipe 21 is closed through the pipe valve 22 to prevent water in the tank 1 from entering the liquid storage pump and liquid storage device behind it through the feed pipe 21 when the tank 1 is filled with water. Then, the tank cover 3 is opened and an appropriate amount of cleaning water and corresponding paint solvent are added into the tank 1 to soak the inside of the tank 1, which can effectively remove the residue inside the tank 1. Finally, the drain pipe 26 is opened through the pipe cover 27 to drain the sewage through the drain pipe 26 for cleaning of the inside of the tank 1.

[0041] In addition, all content not described in detail in this embodiment falls within the scope of existing technology and common knowledge.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
