Description

Technical Field

[0001] The utility model belongs to the technical field of powder spraying, and particularly relates to a powder spraying coloring device. Background Art

[0002] The powder spraying coloring device is a device widely used in industrial production for surface coating and coloring, especially for coating metals, plastics and other materials. This device electrostatically sprays powder coatings onto the surface of workpieces, and then dries and cures them in a baking chamber to form a firm surface coating.

[0003] After retrieval, the existing patent (publication number: CN220590398U) discloses a powder spraying device, including a table board and a second long plate. A first hollow box is fixedly connected to the top of the table board. A first motor is fixedly connected to the left side of the first hollow box. A first long plate is fixedly connected to the inside of the first hollow box. The output end of the first motor penetrates through the outer wall of the first hollow box and is fixedly connected to a first threaded rod. A first slider is rotatably connected to the outer wall of the first threaded rod. A second hollow box is fixedly connected to the bottom of the first slider. A second motor is fixedly connected to the left side of the second hollow box. The output end of the second motor penetrates through the outer wall of the second hollow box and is fixedly connected to a gear. In the utility model, the size is adjusted by the second motor and the gear, so that the size of the spray nozzle can be freely adjusted, and a large amount of powder is avoided from being wasted during the spraying process, greatly reducing the spraying cost.

[0004] However, in the actual use of the above scheme, the spraying angle is fixedly set. However, if the spraying angle is fixed and cannot be adjusted, it may lead to insufficient coverage or overspray on the surface of some parts of the workpiece. Especially for workpieces with complex shapes, different spraying angles may be required for different areas to ensure uniform coating coverage.

[0005] Therefore, the utility model provides a powder spraying coloring device. Summary of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem that the spraying angle is fixed and cannot be adjusted, which may lead to insufficient coverage or overspray on the surface of some parts of the workpiece, the utility model proposes a powder spraying coloring device.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A powder spraying and coloring device of the present utility model includes a base. A pair of front and rear relative rotating rods are rotatably connected to the left side of the top end of the base. The right side of the middle end of the rotating rod is rotatably connected to a first hydraulic rod, and the bottom end of the first hydraulic rod is rotatably connected to the middle side of the top end of the base. The right side of the middle end of the rotating rod is also rotatably connected to a second hydraulic rod. The left side of the top end of the second hydraulic rod is fixedly connected to a telescopic rod, and the telescopic rod is slidably connected to the rotating rod. The middle end of the inner side of the telescopic rod is fixedly connected to a shunt pipe. The bottom end of the shunt pipe is fixedly connected to a plurality of uniformly distributed second hoses. The inner side of the top end of the telescopic rod is fixedly connected to a fixed rod. The bottom end of the right side of the fixed rod is fixedly connected to a plurality of groups of uniformly distributed limiting plates. An electric push rod is rotatably connected to the inner side of the limiting plate. The bottom end of the electric push rod is rotatably connected to a powder spray gun. The middle end of the powder spray gun is rotatably connected to the inner side of the bottom end of the limiting plate. The right side of the shunt pipe is fixedly connected to a first hose;

[0008] Through the above technical solution, the first hydraulic rod extends and contracts by itself, thereby driving the rotating rod to adjust the angle. At the same time, the second hydraulic rod drives the telescopic rod to extend upward, thereby adjusting the height of the powder spray gun, so that the device can spray the top of workpieces at different heights. Then, the electric push rod drives the right side of the powder spray gun to rotate around the connection position between the powder spray gun and the limiting plate, thereby adjusting the spraying angle of the powder spray gun.

[0009] Further, a conveying assembly is arranged on the right side of the first hose. A crushing box is arranged on the top end of the conveying assembly. A first motor is fixedly connected to the top end of the rear side of the crushing box. The output end of the first motor is fixedly connected to a driving gear. The driving gear is meshed and connected with a driven gear on the right side. A first grinding rod is fixedly connected to the front end of the driving gear. A second grinding rod is fixedly connected to the front end of the driven gear. The inner bottom end of the crushing box is fixedly connected to a pair of front and rear relative guide plates;

[0010] Through the above technical solution, the first motor drives the first grinding rod and the second grinding rod to rotate in opposite directions by using the driving gear and the driven gear, thereby grinding and crushing the coating.

[0011] Further, the conveying assembly includes a second motor. A blanking pipe is fixedly connected to the bottom end of the crushing box. A second motor is fixedly connected to the middle end of the right side of the blanking pipe. The output end of the second motor is fixedly connected to a screw blade. A connecting pipe is fixedly connected to the outer wall of the middle end of the left side of the blanking pipe. The connecting pipe is rotatably connected to the screw blade. The connecting pipe is fixedly connected to the first hose;

[0012] Through the above technical solution, the auger blade is driven by the second motor to rotate, so as to convey the pulverized powder material, and the material is conveyed into the shunt pipe through the first hose, and then conveyed into the powder spray gun through the shunt pipe and the second hose for spraying.

[0013] Further, a support frame is fixedly connected to the right side of the top end of the base, and the support frame is fixedly connected to the pulverizing box;

[0014] Through the above technical solution, the pulverizing box is supported by the support frame.

[0015] Further, a feeding hopper is fixedly connected to the top end of the pulverizing box;

[0016] Through the above technical solution, feeding can be facilitated through the feeding hopper.

[0017] Further, the length of the first hose is greater than the total length of the rotating rod and the telescopic rod;

[0018] Through the above technical solution, it is ensured that when the rotating rod and the telescopic rod are extended to the maximum limit, the length is less than that of the first hose, so as to avoid the influence of the first hose on the expansion and contraction of the rotating rod and the telescopic rod.

[0019] The beneficial effects of the present utility model are as follows:

[0020] 1. For a powder spraying coloring device of the present utility model, by adjusting the spraying angle of the powder spray gun, the adjustable spraying angle allows the operator to adjust according to the shape and surface characteristics of the specific workpiece. Workpieces of different shapes may require spraying at different angles to ensure uniform coverage of the powder, thereby ensuring the quality and consistency of the coating. At the same time, by precisely adjusting the spraying angle, it can be ensured that the powder is evenly distributed on the surface of the workpiece, avoiding excessive or insufficient coating in some areas. This is particularly important for coatings requiring high-quality appearance and functionality, such as the surface coating of automotive parts or electronic products.

[0021] 2. For a powder spraying coloring device of the present utility model, the first grinding rod and the second grinding rod rotate towards each other to grind and pulverize the powder material. The particle size and distribution of the powder directly determine its fluidity and uniformity during the spraying process. A suitable powder pulverization process can ensure that the powder particle size is within an appropriate range, usually from dozens to hundreds of micrometers. Finer powder particles are more easily sprayed evenly onto the surface of the workpiece and can form a smooth and uniform coating. At the same time, by precisely adjusting the nozzle angle and optimizing the powder pulverization process, the coating uniformity and quality of the powder coating can be effectively controlled. This linkage ensures consistent and high-quality coating effects in industrial production, is applicable to workpieces of various shapes and sizes, and improves production efficiency and product quality.
