Description
Technical Field
[0001] This utility model relates to the field of metal parts processing technology, and in particular to a metal parts painting device. Background Technology
[0002] Metal fittings refer to the parts or components required for various equipment made of metal, as well as some small metal products. After the metal fittings are produced, they need to undergo a series of processing steps before they can be shipped out for use. Painting is one of the processing steps for metal fittings, which facilitates the beautification and rust prevention of the metal fittings.
[0003] For example, Chinese utility model patent CN220559564U provides a metal parts painting mechanism, including a conveying mechanism, a lifting mechanism installed on one side of the conveying mechanism, and a painting mechanism installed on one side of the lifting mechanism. The painting mechanism includes a protective cover, a rectangular sleeve, a nozzle, and a lifting cylinder. The protective cover is located on one side of the lifting mechanism, and lifting cylinders are symmetrically installed at the lower end of the protective cover. Compared with the prior art, the structure of this utility model is reasonable and practical. It facilitates the effective automated conveying of metal parts and the protective painting, preventing paint particles from affecting workers. It also facilitates the fixation and adsorption of hooks, preventing the hooks from causing the metal parts to move randomly and affecting the painting process. Furthermore, it effectively and evenly paints the metal parts from bottom to top, significantly improving the painting effect.
[0004] While the aforementioned device improves the painting effect, its painting mechanism can only paint one metal part at a time. This one-to-one painting mode is particularly inadequate for large-scale production needs, leading to frequent accumulation of metal parts waiting to be painted at the back of the production line, directly slowing down the overall production pace and efficiency. In addition, the harmful gases released during the painting process not only pollute the working environment but also endanger the health of the workers. Utility Model Content
[0005] This utility model discloses a metal parts painting device, which solves the problem that in the process of using traditional metal parts painting devices, the painting mechanism can only paint one metal part at a time, resulting in frequent accumulation of metal parts waiting to be painted at the back end of the production line, which seriously affects production efficiency, as well as the problem of harmful gas pollution and health hazards caused by painting.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A metal parts painting device includes a housing with two vertically spaced rotating shafts rotatably connected inside. Each rotating shaft has several horizontally fixed rings evenly fixed from top to bottom, and the fixed rings on different rotating shafts do not interfere with each other. The bottom surface of each fixed ring has several hooks evenly surrounding the corresponding rotating shaft. The housing is equipped with a first driving assembly for driving the two rotating shafts to rotate around their respective axes. Vertical spray pipes are slidably connected to the inner walls on both sides of the housing, and each spray pipe is connected to several spray nozzles corresponding to the fixed rings. The top of each paint spraying hose penetrates the top of the housing and extends to the outside of the housing. The top of the housing is equipped with a paint box, and connecting pipes are connected to both sides of the paint box. Each connecting pipe is connected to a flexible hose, and the other end of the flexible hose is connected to the end of the corresponding paint spraying hose located outside the housing. The housing is equipped with two second drive components for driving the corresponding paint spraying hose to move up and down along the inner wall of the housing. The flexible hoses have sufficient length to meet the bending allowance requirements when the paint spraying hose moves. The housing is also equipped with an air treatment component for absorbing and filtering harmful gases. The front of the housing is hinged with a door.
[0008] Compared with the prior art, the present invention has the following beneficial effects:
[0009] Open the chamber door and secure the metal parts to be painted to several hooks in sequence. During suspension, the first drive assembly drives two rotating shafts to rotate around their own axes, causing the fixing rings to rotate and allowing the hooks at the rear of the chamber to be utilized. After all the hooks are filled with metal parts, close the chamber door. Use the paint tank and connect pipes and hoses to supply paint to the spray nozzles, which then spray the paint onto the suspended metal parts. During painting, the first drive assembly drives the fixing rings to rotate, ensuring each metal part is sprayed. Simultaneously, the second drive assembly moves the spray nozzles up and down along the inner wall of the chamber, ensuring the top, bottom, and sidewalls of each metal part are evenly sprayed. This allows for uniform and synchronous painting of multiple metal parts. Furthermore, the air treatment assembly absorbs and filters harmful gases released during painting, preventing direct emission into the air and potential pollution or health risks to workers. This invention is highly practical. By incorporating a rotating shaft, a fixing ring, a hook, and a first drive assembly, it enables simultaneous painting of multiple metal parts. Furthermore, by including a hose, a paint spray pipe, a nozzle, and a second drive assembly, it ensures that the top, bottom, and sidewalls of each metal part are evenly sprayed, effectively improving painting efficiency. Additionally, an air treatment assembly is included to absorb and filter harmful gases released during the painting process, preventing them from being directly emitted into the air and causing pollution or affecting the health of workers.

[0016] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 and Figure 2As shown, this utility model provides a metal parts painting device, including a housing 1. Two vertically spaced rotating shafts 2 are rotatably connected inside the housing 1. Each rotating shaft 2 has several horizontally fixed rings 21 evenly fixed from top to bottom, and the fixed rings 21 on different rotating shafts 2 do not interfere with each other. The bottom surface of each fixed ring 21 is fixed with several hooks 22 evenly surrounding the corresponding rotating shaft 2. The housing 1 is provided with a first driving assembly for driving the two rotating shafts 2 to rotate around their own axes. Vertical spray pipes 3 are slidably connected to the inner walls on both sides of the housing 1, and each spray pipe 3 is connected to several spray nozzles 3 corresponding to the fixed rings 21. 1. The top ends of two paint spray pipes 3 penetrate the top of the housing 1 and extend outside the housing 1. A paint box 4 is provided on the top of the housing 1. Connecting pipes 41 are connected to both sides of the paint box 4. Each connecting pipe 41 is connected to a flexible hose 42. The other end of the flexible hose 42 is connected to the end of the corresponding paint spray pipe 3 located outside the housing 1. The housing 1 is provided with two second drive components for driving the corresponding paint spray pipe 3 to move up and down along the inner wall of the housing 1. The flexible hose 42 has sufficient length to meet the bending allowance requirements when the paint spray pipe 3 moves. The housing 1 is also provided with an air treatment component for absorbing and filtering harmful gases. A door 7 is hinged to the front of the housing 1. Specifically, slide rails (not shown in the figure) are fixed on the inner walls of both sides of the housing 1. The paint spray pipe 3 is slidably connected to the inner wall of the housing 1 through the corresponding slide rails.
[0018] like Figure 2 and Figure 3 As shown, the first drive assembly includes a vertically rotating rod 6 rotatably connected to the bottom surface of the housing 1. A horizontal first gear 61 is coaxially fixed on the rotating rod 6, and horizontal second gears 62 mesh with each other on both sides of the first gear 61. The centers of the two second gears 62 are respectively fixedly connected to the bottom ends of the corresponding rotating shafts 2. The bottom of the housing 1 is provided with a motor 63 for driving the rotating rod 6 to rotate around its own axis. A cavity 11 is opened inside the bottom surface of the housing 1 for the first gear 61 and the second gears 62 to move. When the motor 63 is started, the output end of the motor 63 drives the first gear 61 to rotate, which in turn drives the rotating shaft 2 to rotate through the second gears 62 meshing with the first gear 61. This causes the hooks 22 on the fixed ring 21 to rotate around the rotating shaft 2, so that each suspended metal accessory can be sprayed.
[0019] like Figure 1 and Figure 2As shown, the second drive assembly includes a cylinder 32 vertically fixed to the outside of the housing 1. A horizontal connecting rod 33 is fixed to the output end of the cylinder 32. The end of the connecting rod 33 away from the cylinder 32 is fixedly connected to the outer side of the corresponding paint spray pipe 3 located outside the housing 1. When the cylinder 32 is activated, the output end of the cylinder 32 drives the connecting rod 33 to move up and down, which in turn drives the paint spray pipe 3 to move up and down, so that the top, bottom, and sidewalls of each metal part can be evenly sprayed.
[0020] like Figure 2 As shown, a limiting block 34 is fixed to the upper outer wall of the spray pipe 3 inside the housing 1. The movable distance of the limiting block 34 is equal to the distance between any two adjacent fixing rings 21. The limiting block 34 restricts the movement distance of the spray pipe 3 to prevent it from moving excessively outside the housing 1. The fact that the movable distance of the limiting block 34 is equal to the distance between any two adjacent fixing rings 21 ensures that the spray pipe 3 moves within a minimal range while the spray nozzle 31 sprays the metal parts evenly from top to bottom.
[0021] like Figure 4 As shown, several annular grooves 35 are evenly formed on the surface of the end where the paint spray pipe 3 connects to the hose 42, and a hose clamp 421 is detachably connected to the surface of the connection between the paint spray pipe 3 and the hose 42. The annular grooves 35 increase the friction between the paint spray pipe 3 and the hose 42, making it less likely for the paint spray pipe 3 and the hose 42 to separate. The hose clamp 421 further secures the paint spray pipe 3 and the hose 42. At the same time, the annular grooves 35 and the hose clamp 421 can also be used between the connecting pipe 41 on the paint tank 4 and the hose 42 to improve the firmness of the connection, effectively preventing the hose 42 from falling off due to the movement of the paint spray pipe 3.
[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the air handling unit includes an air intake hood 5 connected to the center of the top of the housing 1. A filter box 52 is located on the top of the housing 1. The top of the air intake hood 5 is connected to the filter box 52 via an air intake pipe 51. A fan 53 is located at the end of the filter box 52 furthest from the air intake pipe 51. A vertical filter plate 54 is located inside the filter box 52, positioned between the air intake pipe 51 and the fan 53. During the spraying process, the fan 53 is activated, drawing harmful gases from the housing 1 through the air intake hood 5 and the air intake pipe 51 into the filter box 52. Because the filter box contains the filter plate 54, the harmful gases are filtered, effectively solving the problem of pollution and health risks caused by the direct emission of harmful gases into the air.
[0023] like Figure 1As shown, a handle 71 is fixed on the box door 7, and an observation window 72 is also provided on the box door 7. The handle 71 makes it convenient for staff to open or close the box door 7; the observation window 72 allows staff to observe the inside of the box 1 in real time during the painting operation.
[0024] like Figure 1 and Figure 2 As shown, the bottom of the paint tank 4 is fixed with several supports 43 that are fixed to the top surface of the tank body 1. By setting the supports 43, the paint tank 4 can be raised, making it easier for the spray paint liquid in the paint tank 4 to flow into the spray pipe 3. In addition, a paint tank door (not shown in the figure) can be set on the paint tank 4, or the paint tank 4 can be connected to the spray paint liquid storage tank through a pipe to realize the operation of adding spray paint liquid to the paint tank 4. A delivery pump can also be set in the paint tank 4 and the delivery pump can be connected to the connecting pipes 41 on both sides of the paint tank 4 to realize the delivery operation of spray paint liquid.
[0025] like Figure 1 and Figure 2 As shown, several support legs 8 are fixed to the bottom surface of the housing 1. By setting the support legs 8, the bottom of the housing 1 is raised while supporting and fixing the entire device, so as to prevent it from affecting the operation of the motor 63.
[0026] In use, the box door 7 is opened by handle 71, and the metal parts to be painted are fixed sequentially onto several hooks 22. During hanging, the motor 63 drives two rotating shafts 2 to rotate around their own axes, thereby rotating the fixing ring 21 and allowing the hooks 22 located at the rear end of the box body 1 to also be utilized. After all the metal parts are hung on the hooks 22, the box door 7 is closed. Paint is then supplied to the spray pipe 3 via the paint box 4, connecting pipe 41, and flexible hose 42, and sprayed onto the suspended metal parts by the nozzle 31. During the painting process, the motor 63 drives the fixing ring 21 to rotate, ensuring that each metal part is sprayed. At the same time, the cylinder 32 is activated, and the output end of the cylinder 32 drives the connecting rod 33 to move up and down, which in turn drives the paint spray pipe 3 to move up and down, so that the top, bottom and side walls of each metal part can be sprayed evenly. In this way, the uniform and synchronous painting operation of multiple metal parts can be achieved. During the spraying process, the fan 53 is activated to draw the harmful gas in the box 1 through the air inlet hood 5 and the air inlet pipe 51 into the filter box 52. Since the filter box is equipped with a filter plate 54, the harmful gas can be filtered, effectively solving the problem of pollution and health impact caused by the direct emission of harmful gas into the air.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
