Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a spraying machine for anti-corrosion coatings of metal products. Background Art

[0002] In the manufacturing process of plate-shaped metal products, the spraying of anti-corrosion coatings is a crucial step, which directly affects the durability, corrosion resistance and appearance quality of the products. Traditionally, the coating spraying of metal products mainly relies on manual operation or simple automated equipment to complete. These methods may perform well in small-scale production or the processing of specific products, but there are many limitations in large-scale and high-standard industrial production.

[0003] Deficiencies of Existing Spraying Machines for Anti-Corrosion Coatings of Metal Products

[0004] Uneven spraying: Traditional spraying equipment often has difficulty in achieving uniform distribution of the coating, especially when dealing with metal plates of different sizes. The uneven coating not only affects the appearance of the product but also may reduce its anti-corrosion performance.

[0005] Low efficiency: Manual spraying or semi-automated equipment requires frequent manual intervention during operation, which limits the continuity and efficiency of production. Most of these spraying machines can only spray one side of plate-shaped metal parts, and subsequent turning over is required.

[0006] Poor adaptability: Many existing spraying machines need to be manually adjusted when dealing with plates of different thicknesses or sizes, which is not only time-consuming but also error-prone. This low adaptability is particularly prominent in diversified product production lines.

[0007] Therefore, the present solution particularly provides a spraying machine for anti-corrosion coatings of metal products to solve the above problems. Content of the Utility Model

At the central position inside the spraying machine chamber, a spraying mechanism is arranged. On the left and right sides inside the spraying machine chamber, plate-shaped metal part feeding mechanisms are symmetrically distributed. On the top box wall inside the spraying machine chamber, a lateral distance adjustment mechanism for adjusting the distance between the two plate-shaped metal part feeding mechanisms is installed.

[0010] The plate-shaped metal part feeding mechanism specifically includes:

[0011] 4 feeding modules evenly distributed at equal intervals along the feeding direction;

[0012] Connecting columns between adjacent feeding modules;

[0013] The feeding module specifically includes:

[0026] Preferably, the longitudinal position adjustment mechanism specifically includes the following structures:

[0027] A first driving lead screw vertically distributed;

[0028] A reduction motor distributed at the bottom end of the first driving lead screw and with its output end docked thereto;

[0029] A first lead screw sleeve threadedly sleeved on the first driving lead screw, and the inner wall of the first lead screw sleeve is connected to the same side surface of the feeding mechanism in a non-fixed state.

[0030] Preferably, the guiding component specifically includes the following structures:

[0031] A guiding column vertically distributed;

[0032] A guiding sleeve that slides sleeved on a guiding column, and the inner tube wall of the guiding sleeve is connected to the same side of the feeding mechanism.

[0033] Preferably, the spraying mechanism specifically includes the following structure:

[0034] An anti-corrosion paint storage tank and a liquid extraction pump distributed on the top of the spraying machine chamber, and the liquid extraction end of the liquid extraction pump is docked inside the anti-corrosion paint storage tank;

[0035] Two liquid guiding pipes docked on the output ends on both sides of the liquid extraction pump;

[0043] Accurate positioning and feeding of the plate: By using four feeding modules symmetrically distributed on the left and right, it can ensure that the plate-shaped metal parts can remain stable whether in the initial introduction or subsequent export, ensuring the uniformity of the coating. The design of the V-shaped groove also adapts to metal plates of different thicknesses, further enhancing the applicable range of the machine.

[0044] Flexible space adjustment: Through the lateral distance adjustment mechanism at the top and the movable feeding mechanism and longitudinal position adjustment mechanism inside each feeding module, it can arbitrarily position plate-shaped metal parts of different lengths and widths, which provides high flexibility for processing metal plates of various sizes.

[0110] Vertically place the plate-shaped metal part to be sprayed and place the lower edge of its front end on the conveyor belt 31221 inside the feeding component 3122 of the feeding module 31 at the entrance, and make its bottom edge stuck inside the V-shaped groove of the belt surface;

[0111] Start the longitudinal position adjustment mechanism 313 inside all the feeding modules 31 to lower the feeding mechanism 312 inside until the conveyor belt 31221 inside the feeding component 3122 reaches the upper edge of the plate-shaped metal part to be sprayed and then stop.

[0112] According to the length of the plate-shaped metal part to be sprayed, start the lateral distance adjustment mechanism 4 to adjust the distance between the two plate-shaped metal part feeding mechanisms 3 until the distance between the two plate-shaped metal part feeding mechanisms 3 is less than two-thirds of the length of the plate-shaped metal part to be sprayed.

[0113] Start the feeding mechanism 312 to make the plate-shaped metal part to be sprayed move smoothly to the spraying area along the feeding path to the right.

[0114] Start the spraying mechanism 2. The liquid extraction pump 22 extracts the coating from the anti-corrosion coating storage tank 21, transports it to the liquid guide box 24 through the liquid guide pipe 23, and uniformly sprays the plate-shaped metal part to be sprayed through the spraying nozzle 25.

[0115] During the spraying operation, the plate-shaped metal part to be sprayed continues to be fed to the right. Its rear end first disengages from the plate-shaped metal part feeding mechanism 3 at the entrance, and at the same time its front end is fed into the plate-shaped metal part feeding mechanism 3 at the exit and is finally fed out inside the spraying machine chamber 1. At this time, the complete spraying operation of the plate-shaped metal part to be sprayed is completed.
