Description
Technical Field
[0001] This application relates to the field of busbar trunking production equipment technology, and in particular to a spraying device for busbar trunking production. Background Technology
[0002] Busbar trunking is widely used in power distribution in power systems. Its surface needs to be coated to improve insulation, corrosion resistance and aesthetics.
[0003] The related technology, disclosed in CN214554637U, describes a spraying device for busbar trunking production. This device includes a spraying box with multiple sets of first through holes on its inner wall. Multiple nozzles are fixedly installed around each set of first through holes. A liquid storage tank is fixedly installed in the middle of the spraying box, and multiple sets of second through holes are provided on its front, back, and top. This utility model describes a spraying device for busbar trunking production. By installing multiple sets of multi-hole nozzles inside the spraying box and outside the liquid storage tank, the paint sprayed by these nozzles is adapted to the shape of the busbar trunking. This allows for the simultaneous spraying of paint onto both the interior and exterior of the busbar trunking without manual operation. This solves the problems of wasted time and health risks associated with traditional manual busbar trunking spraying. Furthermore, a drying box is installed on the left side of the spraying box. Heating through heating pipes allows for rapid drying of the sprayed busbar trunking, accelerating the work process.
[0004] Regarding the aforementioned technology, the inventors have discovered that existing spraying devices for busbar trunking production, due to their inherent design characteristics, typically employ a fixed structure. This makes them unsuitable for adapting to the internal cavities of busbar trunking of different sizes and shapes, resulting in uneven spraying and drying, which affects product quality. Furthermore, traditional devices lack adjustability, making it difficult to efficiently process busbar trunking of various specifications, thus increasing production costs and time. Utility Model Content
[0005] In order to address the problem that existing spraying devices for busbar trunking production, due to their inherent design characteristics, typically employ a fixed structure, which cannot adapt to the internal cavities of busbar trunking of different sizes and shapes, resulting in uneven spraying and drying and affecting product quality, this application provides a spraying device for busbar trunking production.
[0006] The present application provides a spraying device for busbar production, which adopts the following technical solution: a spraying box, a drying box disposed on the rear end face of the spraying box and detachably connected thereto, support feet respectively disposed at the four corners of the lower end face of the spraying box and the drying box, an outer spray nozzle disposed in the inner cavity of the spraying box, a liquid storage tank disposed in the middle of the inner cavity of the spraying box, an inner spray nozzle uniformly disposed on the outer periphery of the liquid storage tank, an adjustable spraying frame disposed on the outer periphery of the liquid storage tank, a drying plate uniformly disposed on the outer side of the inner cavity of the drying box, an adjustable drying rack disposed in the inner cavity of the drying box, an inner drying plate disposed on the outer side of the adjustable drying rack, and an adjustment component for adjusting the adjustable spraying frame and the adjustable drying rack.
[0007] By adopting the above technical solution, a drying box is installed on the rear end of the spraying box. The detachable connection ensures that the two can be quickly separated and assembled as needed, facilitating cleaning and maintenance. Support feet are evenly distributed at the four corners of the lower end faces of the spraying box and drying box, providing stable support and ensuring the stability of the equipment during operation. The outer nozzles are located on the outer side of the spraying box's inner cavity, responsible for spraying the exterior of the busbar trough; the liquid storage tank is located in the middle of the spraying box's inner cavity, used to store the spraying liquid; the inner nozzles are evenly distributed around the outer perimeter of the liquid storage tank, working in conjunction with the outer nozzles to spray the interior of the busbar trough. An adjustable spray rack is installed around the outer perimeter of the liquid storage tank, which can be adjusted to accommodate the spraying needs of busbar troughs of different sizes. The drying box's inner cavity has an outer drying plate and an inner drying plate. The outer drying plate is used to dry the exterior of the busbar trough, while the inner drying plate is used to dry the interior. The adjustable drying rack is installed on the outer and inner drying plates, and can be adjusted to match busbar troughs with different inner cavity sizes. The adjustment components are used to control the flexible adjustment of the adjustable spray gun and adjustable drying gun, ensuring that they can be adapted to different models of busbar trunking.
[0008] As a preferred embodiment, the adjustable spraying rack includes a first movable plate arranged parallel to one side of the liquid storage tank, a second movable plate arranged parallel to the other side of the liquid storage tank, and telescopic plates respectively disposed on the upper surfaces of the first and second movable plates.
[0009] By adopting the above technical solution, the distance between the first movable plate and the second movable plate is adjusted by adjusting the components to match the inner cavity size of the busbar trunking; then, the height of the spraying frame is adjusted by the telescopic plate. This adjustable spraying frame can adapt to the inner cavity of busbar trunking of different sizes, improving the flexibility and efficiency of the spraying operation.
[0010] As a preferred embodiment, it further includes guide tubes fixedly disposed on the inner sides of the first movable plate and the second movable plate, and guide holes disposed on the first movable plate and the second movable plate and communicating with the guide tubes. The other end of the guide tube is fixedly disposed on the outer side of the inner nozzles on both sides of the liquid storage tank, and the guide tube is configured as a telescopic tube with a smooth inner wall.
[0011] By adopting the above technical solution, the guide tube, as a telescopic tube with a smooth inner wall, can effectively guide the spray liquid when the distance between the first and second movable plates changes, ensuring that the inner nozzle can be accurately aligned with the inner cavity of the busbar trunking. The guide hole provides a path for the flow of the spray liquid. Through this design, the guide tube and guide hole work together to ensure that the spray liquid can still be accurately sprayed to all parts of the inner cavity of the busbar trunking when the first and second movable plates are close to or far apart, thereby guaranteeing the coating effect.
[0012] As a preferred embodiment, the adjustable drying rack includes a first support plate, a second support plate disposed opposite to the first support plate, and telescopic plates disposed on the upper surfaces of the first and second support plates respectively, wherein the outer sides of the first and second support plates are connected to the inner drying plate.
[0013] By adopting the above technical solution, the distance between the first and second support plates is adjusted by adjusting the components to ensure that the width matches the width of the busbar trough; then the height of the drying rack is adjusted by the telescopic plate to suit the height position of the busbar trough; in this way, whether it is a narrow trough, a wide trough, or a trough of different heights, the drying rack can be placed stably and accurately above the workpiece through appropriate adjustment, which facilitates efficient drying operations and improves the drying effect and work efficiency.
[0014] As a preferred embodiment, the adjustment assembly includes a first adjustment seat and a second adjustment seat that are slidably connected to the spray box and the drying box respectively, a bidirectional lead screw connected to the first adjustment seat and the second adjustment seat, a movable threaded sleeve adapted to the bidirectional lead screw and disposed on the first adjustment seat and the second adjustment seat, bearing seats disposed at both ends of the bidirectional lead screw, and an adjustment handle disposed at one end of the bidirectional lead screw. The adjustment handle is a manual wheel. The first adjustment seat is fixedly connected to the lower end face of the first movable plate and the first support plate respectively, and the second adjustment seat is fixedly connected to the lower end face of the second movable plate and the second support plate respectively.
[0015] By adopting the above technical solution, the bidirectional lead screw cooperates with the moving sleeves of the first and second adjusting seats. Rotating the manual adjusting handle at one end enables the bidirectional lead screw to rotate, thereby driving the first and second adjusting seats to move relative to or towards each other along the lead screw's axial direction. The bearing seat provides support for the bidirectional lead screw, ensuring its smooth operation. The telescopic plate is adjusted according to the actual height of the busbar trough to ensure comprehensive coverage during the spraying and drying processes. The working principle is that rotating the adjusting handle drives the bidirectional lead screw to rotate, and the threaded engagement of the moving sleeve on the lead screw causes the first and second adjusting seats to move along the lead screw's axial direction, thereby adjusting the distance between the first and second movable plates and their support plates to accommodate busbar trough cavities of different sizes. Simultaneously, the telescopic plate can be adjusted according to changes in the busbar trough height to ensure effective coverage during the spraying and drying processes.
[0016] As a preferred embodiment, the bearing housing is fixedly connected to the lower end face of the spraying box and the drying box, and the bearing housing facilitates the support of both ends of the bidirectional lead screw.
[0017] By adopting the above technical solution, the main function of the bearing housing is to support both ends of the bidirectional lead screw by being fixedly connected to the lower end face of the spraying box and the drying box, so as to ensure that the bidirectional lead screw can operate stably.
[0018] As a preferred embodiment, the outer periphery of the bidirectional lead screw is provided with scale lines.
[0019] By adopting the above technical solution, the scale lines on the outer periphery of the bidirectional lead screw can precisely control the rotation amount of the lead screw, thereby accurately adjusting the positions of the adjustable spraying rack and the adjustable drying rack. The scale line design allows operators to intuitively and accurately read the rotation angle of the lead screw, ensuring the accuracy of the spraying and drying positions. The bidirectional lead screw achieves bidirectional adjustment of the adjustable spraying rack and the adjustable drying rack by rotating left and right, thus adapting to busbars of different specifications.
[0020] In summary, this application includes the following beneficial technical effects: 1. By using the outer and inner spray nozzles together, the inner and outer surfaces of the busbar trunking can be sprayed simultaneously, ensuring uniform and comprehensive coating and improving insulation and corrosion resistance; by using the outer and inner drying plates together, the inner and outer surfaces of the busbar trunking can be dried simultaneously, accelerating the drying speed and preventing coating damage. 2. The adjustable spraying rack and adjustable drying rack can be flexibly adjusted through the adjustment components to adapt to busbars with different internal cavity sizes, thereby enhancing the equipment's versatility and production efficiency.
[0021] 3. The guide tube design ensures that the inner nozzle can still stably guide the spray liquid when adjusting the adjustable spray frame, thus guaranteeing the spraying effect.
[0022] 4. The chute structure facilitates smooth movement of the busbar during spraying and drying, reducing manual intervention for alignment and improving automation. Attached Figure Description

It includes a spraying box 100, a drying box 200 detachably connected to the rear end face of the spraying box 100, support feet 300 located at the four corners of the lower end faces of the spraying box 100 and the drying box 200, outer spray nozzles 5 located inside the spraying box 100, a liquid storage tank 4 located in the middle of the spraying box 100, inner spray nozzles 41 evenly distributed around the outer periphery of the liquid storage tank 4, an adjustable spraying frame located around the outer periphery of the liquid storage tank 4, outer drying plates 91 evenly distributed inside the drying box 200, an adjustable drying rack 8 located inside the drying box 200, an inner drying plate 92 located outside the adjustable drying rack 8, and an adjustment assembly for adjusting the adjustable spraying frame and the adjustable drying rack 8.
[0027] In this invention, a drying chamber 200 is installed on the rear end face of the spraying box 100. The detachable connection ensures that the two can be quickly separated and assembled as needed, facilitating cleaning and maintenance. Support feet 300 are evenly distributed at the four corners of the lower end faces of the spraying box 100 and the drying chamber 200, providing stable support and ensuring the stability of the equipment during operation. Outer nozzles 5 are located on the outer side of the inner cavity of the spraying box 100, responsible for spraying the exterior of the busbar trough; a liquid storage tank 4 is located in the middle of the inner cavity of the spraying box 100, used to store the spraying liquid; inner nozzles 41 are evenly distributed on the outer periphery of the liquid storage tank 4, cooperating with the outer nozzles 5 to spray the interior of the busbar trough. An adjustable spray frame is installed on the outer periphery of the liquid storage tank 4, and can be adjusted to adapt to the spraying needs of busbar troughs of different sizes. The drying chamber 200 has an outer drying plate 91 and an inner drying plate 92 inside. The outer drying plate 91 is used to dry the exterior of the busbar trough, while the inner drying plate 92 is used to dry the interior of the busbar trough. An adjustable drying rack 8 is installed on the outside of the outer drying plate 91 and the inner drying plate 92, and can be adjusted to accommodate busbar troughs with different internal cavity sizes. An adjustment assembly is used to control the flexible adjustment of the adjustable spray rack and the adjustable drying rack 8, ensuring that it can adapt to different models of busbar troughs.
[0028] Please refer to details.

The distance between the first movable plate 711 and the second movable plate 712 is adjusted by adjusting the assembly to match the inner cavity size of the busbar trunking. Then, the height of the spraying frame is adjusted by the first telescopic plate 72. This adjustable spraying frame can adapt to the inner cavity of busbar trunking of different sizes, improving the flexibility and efficiency of the spraying operation.
[0029] Please refer to details. Figure 1 and Figure 2 To ensure effective spraying of the inner side of the busbar trough, the system includes guide tubes 42 fixedly mounted inside the first movable plate 711 and the second movable plate 712, and guide holes 421 connected to the guide tubes 42 on the first and second movable plates 711 and 712. The other end of the guide tube 42 is fixedly mounted outside the inner nozzles 41 on both sides of the liquid storage tank 4. The guide tube 42 is a telescopic tube with a smooth inner wall. As a telescopic tube with a smooth inner wall, the guide tube 42 can effectively guide the spray liquid when the distance between the first movable plate 711 and the second movable plate 712 changes, ensuring that the inner nozzles 41 can accurately align with the inner cavity of the busbar trough. The guide holes 421 provide a path for the flow of the spray liquid. Through this design, the guide tubes 42 and the guide holes 421 work together to ensure that the spray liquid can still be accurately sprayed to various parts of the inner cavity of the busbar trough when the first movable plate 711 and the second movable plate 712 are close to or far apart, thus ensuring the spraying effect.
[0030] Please refer to details. Figure 4 and Figure 5 The adjustable drying rack 8 includes a first support plate 811, a second support plate 812 opposite to the first support plate 811, and second telescopic plates 82 respectively disposed on the upper surfaces of the first support plate 811 and the second support plate 812.

The distance between the first support plate 811 and the second support plate 812 is adjusted by adjusting the components to ensure that the width matches the width of the busbar trough. Then, the height of the drying rack is adjusted by the second telescopic plate 82 to suit the height position of the busbar trough. In this way, whether it is a narrow trough, a wide trough, or a trough of different heights, the drying rack can be placed stably and accurately above the workpiece through appropriate adjustment, which facilitates efficient drying operations and improves the drying effect and work efficiency.
[0031] Please refer to details. Figure 1 and Figure 6The adjustment assembly includes a first adjustment seat 101 and a second adjustment seat 102 slidably connected to the spray box 100 and the drying box 200 respectively, a bidirectional lead screw 11 connected to the first adjustment seat 101 and the second adjustment seat 102, a movable threaded sleeve 103 adapted to the bidirectional lead screw 11 and disposed on the first adjustment seat 101 and the second adjustment seat 102, bearing seats 111 disposed at both ends of the bidirectional lead screw 11, and an adjustment handle 112 disposed at one end of the bidirectional lead screw 11. The adjustment handle 112 is a manual wheel. The first adjustment seat 101 is fixed to the lower end surfaces of the first movable plate and the first support plate 811 respectively. The second adjusting seat 102 is fixedly connected to the lower end face of the second movable plate 712 and the second support plate 812, respectively. The bidirectional lead screw 11 cooperates with the moving screw sleeve 103 of the first adjusting seat 101 and the second adjusting seat 102. By rotating the manual adjusting handle 112 at one end, the bidirectional lead screw 11 can rotate, thereby driving the first adjusting seat 101 and the second adjusting seat 102 to move relative to or towards each other along the lead screw axis. The bearing seat 111 provides support for the bidirectional lead screw 11 to ensure its smooth operation. The telescopic plate is adjusted according to the actual height of the busbar trough to ensure full coverage of the spraying and drying process. The working principle is that by rotating the adjusting handle 112, the bidirectional lead screw 11 is driven to rotate. The threaded engagement of the moving screw sleeve 103 on the lead screw causes the first adjusting seat 101 and the second adjusting seat 102 to move along the lead screw axis, thereby adjusting the distance between the first movable plate 711, the second movable plate 712 and their support plate to adapt to the inner cavity of the busbar trough of different sizes. At the same time, the telescopic plate can be adjusted according to the height change of the busbar trough to ensure effective coverage during the spraying and drying process.
[0032] Please refer to details. Figure 6 The bearing housing 111 is fixedly connected to the lower end face of the spraying box 100 and the drying box 200, and the bearing housing 111 facilitates the support of both ends of the bidirectional lead screw 11. The main function of the bearing housing 111 is to support both ends of the bidirectional lead screw 11 by being fixedly connected to the lower end face of the spraying box 100 and the drying box 200, so as to ensure that the bidirectional lead screw 11 can operate stably.
[0033] Please refer to details. Figure 1 and Figure 6 The bidirectional lead screw 11 has scale lines on its outer circumference, which precisely control the rotation of the lead screw 11, thereby accurately adjusting the positions of the adjustable spray gun and the adjustable drying rack 8. The scale lines allow operators to intuitively and accurately read the rotation angle of the bidirectional lead screw 11, ensuring the precision of the spraying and drying positions. The bidirectional lead screw 11 allows for bidirectional adjustment of the adjustable spray gun and the adjustable drying rack 8 by rotating left and right, thus adapting to different specifications of busbar trunking.
[0034] The implementation principle of the spraying device for busbar trunking production in this embodiment is as follows: The busbar trunking enters the spraying box 100 through the chute 6. By rotating the adjusting handle 112, the bidirectional lead screw 11 is driven to rotate, causing the first adjusting seat 101 and the second adjusting seat 102 to move relative to or towards each other on the bidirectional lead screw 11, thereby adjusting the relative distance between the first movable plate 711, the second movable plate 712, the first support plate 811, and the second support plate 812 to adapt to the inner cavity size of the busbar trunking. The height of the first telescopic plate 72 and the second telescopic plate 82 can be further adjusted to ensure full coverage of spraying and drying. The outer nozzle 5 and the inner nozzle 41 spray the inner and outer surfaces simultaneously. After spraying, the busbar trunking enters the drying box 200, where the outer drying plate 91 and the inner drying plate 92 dry the inner and outer surfaces. The entire process is efficient and the quality is controllable.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
