Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying equipment, in particular to a paint circulating spraying supply device. Background Art

[0002] The paint circulation spray supply device is a supply system used to maintain and control paint in the coating process. It ensures that the paint is delivered to the painting station at a constant pressure and flow rate. This supply device is widely used in many industries such as automobile manufacturing, furniture, and footwear. It improves coating efficiency and quality while reducing material waste.

[0003] The existing patent CN213494429U discloses a paint supply device for spraying: 1. By designing a flow limiting mechanism, the flow rate can be adjusted according to different needs and different objects during the spraying operation. No matter how large the nozzle size is, the flow rate can be adjusted according to the specific situation of the nozzle, which not only facilitates the operation but also makes the spraying operation more perfect; 2. By designing a filtering mechanism, impurities in the paint can be effectively filtered, and the spraying effect will not be affected by problems such as excessive impurities, and the nozzle blockage caused by excessive impurities can be effectively avoided. In addition, the filtering mechanism is detachable and can be cleaned according to the frequency according to different situations;

[0004] This patent solves the problems of uneven spraying and clogging of the nozzle of the supply device and the inability to control the flow rate. However, this patent still has the following shortcomings, such as: this patent only stirs the paint through a stirrer. Since the structure of the stirrer is relatively simple and there is only one stirring station, the stirrer mostly moves along a symmetrical circulation loop when stirring the paint, which is not conducive to increasing the turbulence of the paint, and may cause the paint to be not stirred sufficiently, which may lead to uneven mixing of the substances inside the paint, causing color difference in the paint, and is not conducive to the spraying and use of the paint.

[0005] Therefore, the utility model provides a paint circulating spraying supply device. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-Figure 4 As shown, this embodiment provides a technical solution: a paint circulating spray supply device, comprising a supply barrel 1, a stirring assembly 5, and a humidifying assembly 6, wherein the supply barrel 1 is fixedly connected with a feed port 2, a supply assembly 4 is arranged at the bottom of the supply barrel 1, a top cover 3 is arranged at the top of the supply barrel 1, the stirring assembly 5 is arranged on the top cover 3, the humidifying assembly 6 is arranged on a side of the top cover 3 away from the supply barrel 1, and a transmission assembly 8 is arranged on the stirring assembly 5;

[0030] like Figure 2 As shown, the stirring assembly 5 includes a motor 51 and a turntable 54. The motor 51 is fixedly connected to the top of the top cover 3. The output end of the motor 51 is fixedly connected to a rotating shaft 52. The rotating shaft 52 is located on the inner side of the supply barrel 1. A stirring rod 1 53 is fixedly connected to the rotating shaft 52. The turntable 54 is arranged on the side of the top cover 3 close to the supply barrel 1. A stirring rod 2 55 is fixedly connected to the side of the turntable 54 close to the supply barrel 1. A connecting rod 56 is fixedly connected between the rotating shaft 52 and the stirring rod 2 55. When the rotating shaft 52 rotates, the stirring rod 1 53 is driven to rotate together. The stirring rod 1 53 is installed on the rotating shaft 52 at an angle, and the stirring rod 2 55 is installed on the turntable 54, thereby solving the problem of insufficient stirring of the paint, which may lead to uneven mixing of substances inside the paint and cause color difference in the paint.

[0031] A slider 57 is fixedly connected to one side of the top cover 3 near the turntable 54, and a slide groove 58 is provided on one side of the turntable 54 near the slider 57. The turntable 54 is slidably connected to the top cover 3 through the slider 57 and the slide groove 58. By installing the slider 57 on the top cover 3, the turntable 54 can rotate on the top cover 3 through the slide groove 58, so that the turntable 54 drives the stirring rod 55 to rotate, which is convenient for stirring the paint.

[0032] Furthermore, Figure 3 As shown, the transmission assembly 8 includes a driving wheel 81, a driven wheel 82 and a rack 83. The driving wheel 81 is fixedly connected to one end of the rotating shaft 52 close to the inner side of the turntable 54, the driven wheel 82 is rotatably connected to one side of the top cover 3 close to the driving wheel 81, and the rack 83 is fixedly connected to one side of the turntable 54 close to the driven wheel 82. The driven wheel 82 is meshed with the driving wheel 81 and the rack 83. The rotating shaft 52 drives the driving wheel 81 to rotate clockwise, and the driving wheel 81 drives the stirring rod 1 53 to rotate counterclockwise through the driven wheel 82 and the rack 83, so that the stirring rod 2 55 rotates in the opposite direction to the stirring rod 1 53, thereby further increasing the turbulence of the paint, improving the mixing degree of the paint, and reducing the color difference of the paint.

[0033] The supply assembly 4 includes a water pump 41 and a hose 42. The water pump 41 is fixedly connected to the bottom of the supply barrel 1, and the hose 42 is fixedly connected to the water pump 41. By starting the water pump 41, the paint inside the supply barrel 1 is transported along the hose 42 to the spray gun arranged outside.

[0034] The above solutions also cause the humidity inside the paint to be too high or too low, which causes the paint to be difficult to level or dry after spraying. Figure 4 As shown, the humidifying assembly 6 includes a water tank 61 and a nozzle 63. The water tank 61 is arranged on the top cover 3. The top of the water tank 61 is fixedly connected with a water inlet pipe 62. The nozzle 63 is fixedly connected to a side of the water tank 61 close to the top cover 3. The nozzle 63 is movably inserted on the top cover 3. Clean water is sent into the interior of the water tank 61 along the water inlet pipe 62 and sprayed out along the nozzle 63. Since eight nozzles 63 are installed around the rotating shaft 52 on the top cover 3, the clean water can be sprayed more evenly onto the paint. The paint is stirred by the stirring rod 1 53 and the stirring rod 2 55, so that the clean water is more fully mixed with the paint, further increasing and maintaining the humidity of the paint, which is conducive to the leveling or drying of the paint after being sprayed out.

[0035] The bottom of the supply barrel 1 is provided with an inner groove, and a resistance coil 7 is provided inside the inner groove. By starting the resistance coil 7, the interior of the supply barrel 1 is heated and the moisture inside the paint is evaporated, thereby facilitating the control of excess moisture inside the paint.

[0036] Working principle: Figure 1-Figure 4 As shown:

[0037] When in use: first inject the paint into the supply barrel 1 from the feed port 2, then start the motor 51, the motor 51 drives the stirring rod 1 53 to rotate and stir the paint, at this time, the rotating shaft 52 drives the driving wheel 81 to rotate, the driving wheel 81 drives the driven wheel 82 to rotate, the driven wheel 82 rotates in the opposite direction to the driving wheel 81, and the driven wheel 82 drives the turntable 54 to rotate in the same direction as the driving wheel 81 through the rack 83, so that the stirring rod 2 55 and the stirring rod 1 53 stir the paint in opposite directions, and the stirring rod 2 55 can stir the paint at the bottom of the inner wall of the supply barrel 1 to the upper part of the supply barrel 1, thereby making the materials inside the material mixed evenly and reducing the color difference of the paint. When the stirring rod 1 53 and the stirring rod 2 55 stir the paint, according to the humidity of the paint, clean water is sent from the water inlet pipe 62 into the inside of the water tank 61, and then the clean water is sprayed from the nozzle 63 to the inside of the paint, thereby changing the humidity of the paint, which is conducive to the leveling or drying of the paint after being sprayed out. If the humidity of the paint is too high, start the resistance coil 7 to reduce the moisture inside the paint.
