Technical Field
[0001] This utility model relates to the field of metal parts painting technology, and in particular to a surface painting device. Background Technology
[0002] Hardware parts refer to various metal utensils and components made from metals such as iron, steel, and aluminum through physical processing such as forging, rolling, and cutting. During the processing of hardware parts, in order to achieve rust and corrosion prevention or to enhance aesthetics, it is necessary to spray paint on the outer surface of the hardware parts. Hardware parts come in various shapes, and some tubular hardware parts require surface painting. In the process of painting tubular hardware parts, a painting device is needed to evenly spray paint onto the surface of the tubular hardware parts.
[0003] A search revealed that patent CN221360610U discloses a surface painting device for tubular hardware. This device uses a fixing structure to secure the hardware from the inner wall of the tubular hardware, thus facilitating painting of the outer wall. However, this device can only process one hardware component at a time, resulting in low processing efficiency and an inability to guarantee uniform paint application. Therefore, further improvements are needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface painting device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surface painting device, comprising a housing, a first motor fixed on the lower surface of the housing, a support plate fixedly connected to the top output shaft of the first motor through the bottom wall of the housing, a plurality of vertical shafts rotatably connected to the side of the support plate via bearings, a support assembly for fixing tubular hardware at the top of each vertical shaft, a rotatable painting assembly installed on the top wall of the housing, a second motor for driving the painting assembly to rotate installed on the upper surface of the housing, and a pump body for pumping paint into the painting assembly installed on the upper surface of the housing, and two symmetrical side doors rotatably connected to one side of the housing via hinges.
[0006] Furthermore, the top surface of the vertical shaft is provided with threads, and the support assembly includes an internally threaded cylinder rotatably connected to the top of the vertical shaft. The top of the internally threaded cylinder is rotatably connected to a ring plate through a bearing. The ring plate is slidably connected to the vertical shaft.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1-3 As shown, a surface painting device is disclosed, comprising a housing 1, a first motor 2 fixed on the lower surface of the housing 1, a support plate 3 fixedly connected to the top output shaft of the first motor 2 through the bottom wall of the housing 1, a plurality of vertical shafts 4 rotatably connected to the side of the support plate 3 via bearings, a support assembly 5 for fixing tubular hardware at the top of each vertical shaft 4, a rotatable painting assembly 8 installed on the top wall of the housing 1, a second motor 9 for driving the painting assembly 8 to rotate installed on the upper surface of the housing 1, and a pump body 10 for pumping paint into the painting assembly 8 installed on the upper surface of the housing 1, and two symmetrical side doors 16 rotatably connected to one side of the housing 1 via hinges.
[0022] The top surface of the vertical shaft 4 is threaded. The support assembly 5 includes an internally threaded cylinder 51 that is rotatably connected to the top of the vertical shaft 4. The top of the internally threaded cylinder 51 is rotatably connected to a ring plate 52 via a bearing. The ring plate 52 is slidably connected to the vertical shaft 4. The support assembly 5 also includes a plurality of inclined rods 53 that are hinged to the top of the vertical shaft 4. A support rod 54 is hinged to the middle of the inclined rod 53, and the other end of the support rod 54 is hinged to the outer wall of the ring plate 52.
[0023] After the internal threaded cylinder 51 is rotated along the thread at the top of the vertical axis 4, the internal threaded cylinder 51 will drive the ring plate 52 to move due to the restriction of the support rod 54 and the inclined rod 53. This will push the inclined rod 53 upward through the support rod 54, and the inclined rod 53 will press against the inner wall of the tubular hardware to fix the hardware.
[0024] The bottom end of the vertical shaft 4 is fixed with a first gear 6, and the inner bottom wall of the housing 1 is fixed with an internal gear ring 7. The first gear 6 meshes with the internal gear ring 7.
[0025] When the first motor 2 drives the tray 3 to rotate, the vertical shaft 4 will rotate with the tray 3. Since the first gear 6 meshes with the internal gear ring 7, the vertical shaft 4 will also rotate, so that the fixed hardware can rotate on its own axis while revolving around the sun.
[0026] The paint spraying assembly 8 includes a bent pipe 81 that is rotatably connected to the top wall of the housing 1 via a bearing. Multiple nozzles 82 are fixed to the side wall of the bent pipe 81. A drain pipe 13 is fixedly connected to the drain port of the pump body 10. A sealing sleeve 14 is fixed to the other end of the drain pipe 13. The sealing sleeve 14 is rotatably connected to the top of the bent pipe 81. The inlet of the pump body 10 is connected to the paint bucket.
[0027] The paint can be drawn from the paint bucket through the pump body 10, then enters the inside of the bend pipe 81 through the drain pipe 13, and finally is sprayed out from the nozzle 82.
[0028] The bottom output shaft of the second motor 9 is fixedly connected to the driving gear 11, and the top surface of the bent tube 81 is fixed with the driven gear 12, and the driving gear 11 and the driven gear 12 mesh.
[0029] The second motor 9 can drive the bent pipe 81 to rotate through the meshing transmission of the driving gear 11 and the driven gear 12.
[0030] A waste discharge pipe 15 is fixedly connected to the bottom wall of the housing 1. Paint sprayed into the housing 1 can be discharged through the waste discharge pipe 15.
[0031] Working principle: Open the side door 16, place the tubular hardware onto the top surface of a vertical shaft 4, and then rotate the internally threaded cylinder 51 on the surface of the vertical shaft 4. This causes the inclined rod 53 at the top of the vertical shaft 4 to press against the inner wall of the tubular hardware, thus fixing the tubular hardware. In this way, tubular hardware is fixed on the top surface of each vertical shaft 4. Next, close the side door 16 and start the first motor 2, the second motor 9, and the pump body 10. The pump body 10 pumps paint into the bent pipe 81 and then sprays it out from the nozzle 82. During this process, the first motor 2 drives the hardware to revolve and rotate within the housing 1, and the second motor 9 drives the nozzle 82 on the side wall of the bent pipe 81 to rotate, achieving uniform painting of the hardware surface. After painting is completed, rotate the internally threaded cylinder 51 on the surface of the vertical shaft 4 downwards, thereby pulling the inclined rod 53 downwards to disassemble the hardware.
[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
