DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] 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 the 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.

[0020] Embodiment

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, a painting device suitable for the manufacture of mud pumps proposed in an embodiment of the present utility model includes a painting box 1, a placement table board 2, a top cover 3 and a box door 4. A box door 4 is rotatably connected to the side wall of the painting box 1, which is convenient for effectively blocking the painting box 1 by using the box door 4 and facilitating stable and effective painting treatment of workpieces. An exhaust fan 301 is embedded in the top cover 3 arranged on the top of the painting box 1, and the exhaust fan 301 is stably installed on the upper part of the painting box 1 by using the top cover 3. After the painting treatment of the workpiece is completed, the exhaust fan 301 is turned on to extract the air in the internal cavity of the painting box 1, forming a negative pressure in the internal cavity of the painting box 1. Under the action of the negative pressure, external air enters the internal cavity of the painting box 1 from the lower air inlet slot 107, making the air in the internal cavity of the painting box 1 flow, effectively blowing the workpiece, accelerating the solidification speed of the paint, and improving the painting efficiency of the workpiece. Moreover, the placement table board 2 is arranged in the internal cavity of the painting box 1, forming a stable workpiece bearing platform inside the painting box 1, so that the workpiece can be stably placed in the internal cavity of the painting box 1 for painting treatment. An electric heating wire 105 is placed on the upper part of the air inlet hood 104 fixedly connected to the inner wall of the painting box 1. When the exhaust fan 301 extracts the air in the internal cavity of the painting box 1, the electric heating wire 105 is powered on to heat the air entering the internal cavity of the painting box 1, and the hot air blows on the workpiece to accelerate the solidification of the paint. And an air inlet filter screen 106 arranged below the air inlet hood 104 is fixedly connected to the inner wall of the painting box 1 to filter the air entering the painting box 1, removing the dust in the air and avoiding dust pollution of the painted surface on the workpiece. An air inlet slot 107 is opened on the bottom side wall of the painting box 1, which is not convenient for external air to smoothly enter the internal cavity of the painting box 1.

[0022] As Figure 1 and Figure 3As shown, in some embodiments, the placing table board 2 includes a placing area 201 and a placing surrounding edge 202 which are integrally arranged. A liquid accumulation groove 203 that is recessed downward is formed between the placing area 201 and the placing surrounding edge 202. The bottom of the liquid accumulation groove 203 is provided with uniformly distributed leakage holes, which are convenient for collecting the paint on the flowing placing table board 2 into the liquid accumulation groove 203 and then discharging it from the leakage holes and dropping into the collection groove 102 below. Moreover, uniformly distributed ventilation holes 205 are formed in the placing area 201, which are convenient for the air entering the inner cavity of the paint spraying box 1 from the air inlet hood 104 to smoothly pass through the ventilation holes 205 and blow onto the workpiece placed on the upper part of the placing area 201, accelerating the paint curing speed and improving the paint spraying efficiency. A rib 204 is integrally arranged on the upper surface of the placing area 201, separating the workpiece from the upper surface of the placing area 201, which is convenient for the air to effectively blow the workpiece. And the edge part of the placing surrounding edge 202 is slidably abutted against the inner wall of the paint spraying box 1, and the lower part is abutted against the upper part of the placing ring plate 101 arranged on the inner wall of the paint spraying box 1, which is convenient for stably placing the placing table board 2 inside the paint spraying box 1, ensuring stable use, and serving as a bearing platform for placing the workpiece to stably place the workpiece for paint spraying treatment.

[0023] As Figure 1 and Figure 2As shown, in some embodiments, air-permeable perforations are evenly distributed on the air inlet hood 104, facilitating the smooth passage of air through the air inlet hood 104. The air enters the inner cavity of the upper paint spraying box 1 in a dispersed and uniform manner through the air inlet hood 104, and blows on the workpieces placed on the placing table board 2. A sealing ring is arranged at the connection part between the edge of the air inlet filter screen 106 below the air inlet hood 104 and the inner wall of the paint spraying box 1. The air inlet filter screen 106 effectively filters the air entering the interior of the paint spraying box 1, preventing dust in the air from accumulating on the paint surface of the workpieces and improving the quality of workpiece painting. The air inlet notches 107 at the bottom of the paint spraying box 1 are distributed in a circular array, facilitating the effective passage of external air into the inner cavity of the paint spraying box 1. The flowing air accelerates the solidification speed of the paint sprayed on the workpieces, improving the painting efficiency. At the same time, the gap between the two is sealed with a sealing ring to prevent air from passing through. A collecting groove 102 is fixedly connected to the inner wall of the paint spraying box 1 between the air inlet hood 104 and the placing ring plate 101. The end of the drain pipe 103 connected to the bottom of the collecting groove 102 passes through the side wall of the paint spraying box 1 and extends to the outside, effectively collecting the paint dripping from the placing table board 2 and discharging it from the drain pipe 103 to ensure the cleanliness inside the paint spraying box 1 for long-term stable use. A spray head is arranged in the cavity above the placing table board 2 inside the paint spraying box 1. The spray head is arranged on the driving component arranged on the inner wall of the paint spraying box 1. The spray head is connected to the pipeline for transporting paint, stably transporting the paint into the spray head and spraying it onto the workpieces for stable and effective painting treatment. At the same time, during use, the driving component is used to drive the spray head to rotate in the paint spraying box 1 for effective painting treatment of the workpieces, improving the painting efficiency.

[0024] As Figure 1 shown, in some embodiments, the box door 4 is arranged at the position of the workpiece access notch opened on the side wall of the paint spraying box 1. Installing the box door 4 on the paint spraying box 1 facilitates closing the box door 4 during use to block the workpiece access notch of the paint spraying box 1, thereby painting the placed workpieces and ensuring stable use. A handle is arranged on the box door 4. The installed handle facilitates the user to smoothly open and close the box door 4. At the same time, a door lock is installed at the handle position of the box door 4, which can stably and effectively limit and fix the box door 4 on the paint spraying box 1 when the box door 4 is closed.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
