Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing, in particular to a paint spraying device for metal product processing. Background Art

[0002] Metal products are pipes made of metal materials. In production and life, metals are often damaged by various materials under the influence of the environment, resulting in performance degradation or deterioration of the state. Spraying paint on the metal surface is a very important means of maintaining metal corrosion.

[0003] In the existing metal product painting process, the spacing between multiple paint spray heads used for painting is usually fixed. When processing some metal products with a wider width, a mechanism is required to control the paint spray head to reciprocate multiple times to thoroughly paint its surface, which has certain disadvantages in efficiency. When painting some metal products with a narrower width, the paint sprayed by some paint spray heads will exceed the range of the metal products, thereby causing a waste of paint. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

An adjusting mechanism is also provided, and the adjusting mechanism is used to adjust the spacing between multiple movable plates 7 to the same distance. By setting the cross bar 5, the movable part 6, the movable plate 7 and the adjusting mechanism, the adjusting mechanism can drive multiple paint spray heads 9 to adjust the spacing at the same time when adjusting the spacing between the multiple movable plates 7. The multiple paint spray heads 9 after the spacing is adjusted, in conjunction with the extension and retraction of the electric push rod 8, can be adapted to the painting of metal products of different widths. When painting metal products with a wider width, the painting can be completed at one time, thereby improving the painting efficiency. When painting metal products with a narrower width, it can be avoided that the paint is sprayed outside the metal products, thereby avoiding waste of resources.

[0020] Specifically, the adjustment mechanism includes a roller 12 rotatably installed in the casing 3, and the roller 12 is driven by a first motor 13 arranged on the casing 3. A plurality of strip holes 14 are opened on the side wall of the roller 12, wherein the middle strip hole 14 is vertically arranged, and the remaining strip holes 14 are symmetrically inclined, and the inclination angle increases step by step. A round rod 15 that slides with the strip hole 14 is fixedly arranged on the back of the movable plate 7. Specifically, when the roller 12 is driven to rotate, the round rod 15 on the back of the movable plate 7 slides in the strip hole 14 on the roller 12, and cooperates with the guidance of the two cross bars 5. The middle movable plate 7 remains in place, while the multiple movable plates 7 on both sides expand or contract outward synchronously, thereby realizing the adjustment of the spacing between multiple paint spray heads 9.

[0021] Among them, when the width of the metal product is very narrow, after the spacing between multiple paint spray heads 9 is adjusted to the minimum position, in order to prevent the paint sprayed by some paint spray heads 9 from exceeding the range of the metal product, the connection end of the infusion main pipe 11 and the corrugated hose 10 in the present application is also installed with a solenoid valve 16. Specifically, the opening of multiple solenoid valves 16 can be controlled by a controller to achieve the change of the spraying area, thereby further improving the practicability of the device.

[0022] Specifically, the conveying mechanism includes a plurality of conveying rollers 17 rotatably installed in the frame 1 and a driving element driving the plurality of conveying rollers 17 to rotate.

[0023] In addition, in the process of conveying metal products by the conveying mechanism, in order to ensure that the metal products can be conveyed in the center, in the present application, a correction mechanism is also installed in the frame 1, and the correction mechanism includes a pair of bidirectional screws 18 rotatably arranged in the frame 1, and the two bidirectional screws 18 are connected by a synchronous belt pulley set 19 for transmission, and one of the bidirectional screws 18 is driven by a second motor 20 arranged on the side of the frame 1, and threaded sleeves 21 are symmetrically installed on the two threaded parts of the bidirectional screw 18, and a support plate 22 is fixedly installed on the threaded sleeve 21, and a plurality of correction rods 23 are installed on the support plate 22, and the plurality of correction rods 23 are arranged at intervals between the conveying roller 17.

[0024] Furthermore, a roller sleeve 24 is rotatably mounted on the deflection correcting rod 23. The arrangement of the roller sleeve 24 reduces the friction resistance between the deflection correcting rod 23 and the side of the metal product, so that the metal product can be transported more smoothly.
