[0003] However, although the metal product surface spraying equipment in the prior art has achieved comprehensive spraying and drying and shaping, it still has some shortcomings: the existing metal product surface spraying equipment, on the basis of achieving comprehensive spraying, only sprays the surface of the metal product, and as mentioned in the comparative documents, the shapes of metal products are varied. When encountering cylindrical or tubular metal products, the above-mentioned spraying equipment cannot synchronously spray the inner wall of such metal products, resulting in a small scope of use. Secondly, the spraying efficiency of the single up and down moving booster nozzle is biased. Utility Model Content

At the same time, the outer walls of the inner nozzle 2 and the outer nozzle 4 are both provided with booster nozzles. The upper end of the inner nozzle 2 is connected to the first electric push rod 21, and the first electric push rod 21 is fixed to the center of the top plate of the device frame 1. The outer wall of the outer nozzle 4 is connected to a stabilizing frame 42 and a second electric push rod 41, and the second electric push rod 41 is connected to the middle of the outer nozzle 4.

[0021] In this embodiment, a device frame 1 is provided with an inner nozzle 2 on the inner side of the device frame 1 to constitute the main structure of the metal product surface spraying equipment involved in this application.

[0022] Specifically, the booster nozzles arranged on the outer wall of the inner nozzle 2 are symmetrically arranged in a double row structure, and the booster nozzles on the outer wall of the outer nozzle 4 are single row structures arranged toward the inside.

[0023] Specifically, the inner hose 36 and the outer hose 37 are both made of elastic and retractable hose materials, so as to facilitate the up and down movement of the inner nozzle 2 and the left and right movement of the outer nozzle 4.

[0024] Specifically, the stabilizing frame 42 is configured as two hinged connecting rod structures, and the stabilizing frame 42 maintains telescopic movement in the horizontal direction, thereby enhancing the movement stability of the outer nozzle 4.

[0025] As a preferred embodiment, the second electric push rod 41 is provided to facilitate distance adjustment according to the wall thickness of cylindrical or pipe pile-like metal products. The distance adjustment is mainly for placing such metal products in the distance between the inner nozzle 2 and the outer nozzle 4.

[0027] It should be noted that when it is necessary to perform single-sided local spraying on the cylindrical or tubular metal products mentioned in this application, it is only necessary to install a manual control valve on the hose, that is, if only the inner wall of the metal product is to be sprayed, the valve in the outer hose 37 can be closed.

[0032] Specifically, two meshing gears are provided in the gear box 53 , one of which is connected to the output end of the motor 52 , and the inner side of the other gear is connected to a rotating shaft, the bottom of which is rotatably connected to the fixed plate 51 , and the top of the rotating shaft is fixed at the center of the turntable 54 .

[0033] It should be noted that the clamping clip 56 uses the same components involved in the prior art reference document.

[0034] During use, when spraying cylindrical or tubular metal products, first clamp and fix the lower end of the metal product by means of a clamp, then lower the inner nozzle by means of a first electric push rod and insert it into the interior of the metal product, and at the same time adjust the distance between the outer nozzle and the outer wall of the metal product by means of a second electric push rod, and then start the motor and the booster pump through the booster nozzle, so that the metal product is sprayed in all directions while the clamping assembly drives the metal product to rotate, thereby increasing the scope of application of the spraying equipment for metal products of different shapes, and utilizing the vertically arranged booster nozzles provided on the outer walls of the inner nozzle and the outer nozzle, and with the auxiliary driving action of the clamping assembly, a synchronous large-area spraying effect can be achieved in the height direction of the metal product, thereby improving the spraying efficiency.

It increases the application range of the spraying equipment for metal products of different shapes and structures on the basis of the existing metal product surface spraying equipment technology, improves the spraying efficiency, and can perform local spraying operations on such metal products.
