DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 6 , in the embodiment of the present utility model, a spraying device for processing a desk rack includes a bottom shell 100, a protection mechanism 200 is arranged above the bottom shell 100, and an adjustment mechanism 400 is provided in a supporting manner for the protection mechanism 200, and a conveying mechanism 300 is arranged above the protection mechanism 200;

[0024] The protection mechanism 200 includes a rotating box 210, and the bottom end of the rotating box 210 is rotatably connected to the top surface of the bottom shell 100. A connecting plate 220 is fixedly connected to the top surface of the rotating box 210, and a ring body 230 is arranged above the connecting plate 220. A cloth cylinder 240 is arranged between the ring body 230 and the connecting plate 220. The top end of the cloth cylinder 240 is fixedly sleeved with the bottom end of the inner side wall of the ring body 230, and the bottom end of the cloth cylinder 240 is fixedly connected to the top surface of the connecting plate 220. A plurality of guide plates 250 are fixedly connected to the inner side wall of the ring body 230, and one side of each of the plurality of guide plates 250 is fixedly sleeved with the inner side wall of the cloth cylinder 240. A connecting ring 251 is fixedly connected to the bottom end of each of the plurality of guide plates 250, and one end of each of the plurality of connecting rings 251 penetrates the outer side wall of the cloth cylinder 240 and is fixedly connected to the outer side wall of the cloth cylinder 240.

[0025] Specifically, during use, the conveying mechanism 300 is utilized to transport the table frame components. Then, the user can control the distance between the annular body 230 and the connecting plate 220 through the adjusting mechanism 400. When the parts on the conveying mechanism 300 are transported above the annular body 230, the adjusting mechanism 400 is activated to move the annular body 230 upward, so that the cloth cylinder 240 wraps the components. At the same time, multiple automatic spray guns are fixed inside multiple connecting rings 251 through connecting pieces, so that the multiple automatic spray guns spray the parts inside the cloth cylinder 240. At the same time, when the spray guns are spraying paint, the automatic spray guns can be adjusted through the adjusting mechanism 400 to move along with the annular body 230 and the guide plate 250 to spray paint on various parts of the parts. The cloth cylinder 240 surrounds the paint mist to reduce the impact of the paint mist on the external environment. At the same time, the upper part of the cloth cylinder 240 is connected to the guide plate 250 and is limited. When the spray gun moves downward, the cloth cylinder 240 is not easily in contact with the parts, avoiding affecting the spraying effect of the parts. And both the top and bottom ends of the cloth cylinder 240 and the connection part with the connecting ring 251 are bonded to the annular body 230, the connecting plate 220 and the connecting plate 220 through glue, which is convenient for the user to replace. After use, the cloth cylinder 240 can be directly removed and replaced, thus facilitating the user to use. The cloth cylinder 240 is made of soft cloth. After the annular body 230 and the connecting plate 220 are close to each other, the part of the cloth cylinder 240 that is not connected to the guide plate 250 can automatically relax.

[0026] Embodiment 1

[0027] As Figures 1 - 4 shown, in this embodiment, a plurality of pipe clamps are fixedly connected to the top surface of the annular body 230, and a plurality of suction pipes 231 are fixedly connected inside the plurality of pipe clamps. A plurality of suction pipes 231 are provided with a suction pump, and one end of each of the plurality of suction pipes 231 is fixedly connected to the suction end of the suction pump. A stepping motor is arranged inside the bottom shell 100, and the motor shaft of the stepping motor penetrates the top surface of the bottom shell 100 and is fixedly connected to the center of the bottom surface of the rotating box 210.

[0028] In this embodiment, the suction end of the suction pump is connected to a multi-way connector, and the multi-way connector is connected to the plurality of suction pipes 231. Then, when the spray gun is spraying paint, the suction pump is started to suck the paint mist floating in the cloth cylinder 240 through the plurality of suction pipes 231, thereby reducing the impact of the paint on the surrounding environment. And when the user is using, the stepping motor can be started to drive the rotating box 210 to rotate, and the rotating box 210 synchronously drives the annular body 230 and the plurality of guide plates 250 to rotate through the adjusting mechanism 400, so that the spray gun can spray the parts during rotation.
