AI Technical Summary
When existing powder spraying equipment sprays large flat workpieces, the impact force of the spray head is relatively large, which can easily cause damage to the workpiece, and the spraying is uneven, so that the powder is large and small when it is spit out.
A powder atomizer nozzle for spraying large-plane workpieces is designed, including a nozzle body, which consists of a cup cover, a conductive base, a first powder board and a second powder board. The powder rotates through the powder channel. After passing through the first powder board and the second powder board, the impact force becomes flexible and the powder is sprayed evenly.
The uniform spraying of powder is achieved, reducing damage to the workpiece during the spraying process, and ensuring the soft and uniform spraying effect of the powder.

Technical Field
[0001] The utility model relates to the technical field of powder atomizers, in particular to a powder atomizer nozzle used for spraying large flat workpieces. Background Art
[0002] Powder spraying is the process of spraying powder coating onto the surface of a workpiece using powder spraying equipment. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; the powdery coating is baked at high temperature to level and solidify, becoming a final coating with different effects.
[0003] When existing powder spraying equipment is used to spray large flat workpieces, the impact force of the nozzle is often relatively large, which can easily cause damage to the workpiece.
[0004] Therefore, there is an urgent need for a powder atomizer nozzle for spraying large flat workpieces to solve the above problems. Utility Model Content
[0005] In view of this, in order to solve the problem that the spraying of large flat workpieces in the technical background often has uneven powder spraying and the powder is sometimes large and sometimes small, the utility model proposes a powder atomizer nozzle for spraying large flat workpieces. The specific technical solution is as follows:
[0006] A powder atomizer spray head for spraying a large flat workpiece, comprising a spray head body, the spray head body comprising an outermost cup cover, a conductive base connected to a powder spraying device, and a first powder plate and a second powder plate arranged inside the cup cover, the first powder plate and the second powder plate being arranged in parallel, and the first powder plate and the second powder plate being connected by a powder plate connecting column perpendicular thereto;
[0007] An annular powder outlet is formed between the outer periphery of the second powder plate and the inner wall of the cup cover.
[0008] Furthermore, a powder channel is opened inside the nozzle body. According to the force of the powder spraying equipment, the powder rotates through the first powder plate inside the cup cover body and the second powder plate after passing through the powder channel, and the impact force of the powder is converted into flexibility, and the powder is sprayed out from the powder outlet.
[0009] Furthermore, the outer periphery of the first powder plate is arc-shaped and bends toward the powder outlet.
[0010] Furthermore, the first powder plate and the second powder plate are both circular, and the diameter of the first powder plate is smaller than the diameter of the second powder plate.
[0011] The above technical solution has the following beneficial effects:
[0012] The utility model is connected to a powder spraying device. By using the powder spraying device, powder enters a powder channel and rotates, passes through a first powder plate, and is evenly dispersed, passes through a second powder plate, and is evenly dispersed again, and the impact force of the powder is converted into flexibility, and the powder is sprayed from a gap space between a cup cover and the powder plate, that is, a powder outlet, so that the powder can be sprayed on the workpiece softly and evenly.
