Description

Technical Field

[0001] The utility model relates to an air nozzle structure capable of adjusting the air volume, in particular to an air nozzle structure capable of adjusting the air volume which is applied to powder spraying or recycling spraying operations. Background Art

[0002] Dry powder coating is a common method for improving the appearance, corrosion resistance, special functions and durability of fasteners such as screws. Powder coating is a dry finishing process in which a fine powder is applied to the metal surface and then cured under heat to form a hard, protective and aesthetic surface.

[0003] like Figure 1 As shown, during conventional spraying operations, powder is sprayed from top to bottom onto the fastener seat surface P11, but the suction nozzle P20 for recovering the sprayed material is placed flat, so the powder easily falls onto the edge P12 of the fastener head, causing the head to stick to the material. In addition, when multiple suction nozzles are in operation, all suction nozzles are connected to the same collecting pipe P30, so the suction volume is consistent and cannot be adjusted individually. Utility Model Content

[0004] The utility model is a wind nozzle structure with adjustable air volume, which is mainly used to solve the problem that the flow rate of the wind nozzle cannot be effectively controlled individually during powder spraying or recycling spraying, resulting in poor spraying or recycling spraying performance.

[0009] A blade damper, which is composed of a plurality of air volume adjustment blades and is arranged on the cross section of the air duct, wherein the end of each of the air volume adjustment blades has a first fulcrum, which is rotatably clamped on the air nozzle housing or the air nozzle cover; and a second fulcrum, which is rotatably clamped on the air volume adjustment ring;

[0010] The blade air valve is driven by the air volume adjustment ring so that the plurality of air volume adjustment blades change the gas flow rate of the air duct.

[0011] In a preferred embodiment of the present invention, a fixing ring is provided at the joint between the nozzle shell and the nozzle cover.

[0041] In order to enable anyone familiar with the relevant skills to understand the technical content of the utility model and implement it accordingly, and according to the contents disclosed in this specification, the scope of the patent application and the drawings, anyone familiar with the relevant skills can easily understand the relevant purposes and advantages of the utility model. Therefore, the detailed features and advantages of the utility model will be described in detail in the implementation mode.

[0042] like Figures 2 to 4 As shown, this embodiment is a wind nozzle structure 100 capable of adjusting air volume, which includes: a wind nozzle housing 10 ; a wind nozzle cover 20 ; an air volume adjustment ring 30 ; and a blade damper 40 .

[0043] The air nozzle housing 10 is a first main supporting structure of the air nozzle structure 100 with adjustable air volume. The air nozzle housing 10 has an air volume control window 110 and a first air port 120 .

[0044] The air nozzle cover 20 is the second main supporting structure of the air nozzle structure 100 with adjustable air volume. When the air nozzle cover 20 and the air nozzle housing 10 are integrated into one, they can form the main supporting structure of the air nozzle structure 100 with adjustable air volume.

[0045] When the nozzle cover 20 and the nozzle housing 10 are integrated, a receiving space 210 is formed and the nozzle cover 20 has a second air port 220 . The receiving space 210 is connected to the air volume control window 110 , the first air port 120 and the second air port 220 .

[0046] In order to firmly combine the nozzle housing 10 and the nozzle cover 20 into one, a fixing ring 230 may be provided at the joint between the nozzle housing 10 and the nozzle cover 20. The fixing ring 230 also has the function of achieving airtightness between the nozzle housing 10 and the nozzle cover 20.

[0047] The air volume adjustment ring 30 is mainly used to control the gas flow of the nozzle structure 100 with adjustable air volume. The air volume adjustment ring 30 is rotatably arranged in the accommodating space 210 and has an inner diameter wind tunnel 310. The first air port 120, the second air port 220 and the inner diameter wind tunnel 310 form the nozzle structure 100 with adjustable air volume, and the main air duct 320 inside it.

[0048] One side of the air volume adjustment ring 30 is combined with an air volume adjustment lever 330 protruding from the air volume control window 110 . When the air volume adjustment lever 330 is turned, the air volume adjustment ring 30 can be driven to rotate in the accommodating space 210 .

[0049] like Figure 5 and Figure 6 As shown, the blade damper 40 is composed of a plurality of air volume adjustment blades 410 and is disposed on a section of the air duct 320. Therefore, the blade damper 40 can effectively control the cross-sectional area of ​​the air duct 320, thereby achieving the control of the gas flow rate of the air nozzle structure 100 with adjustable air volume. In order to effectively control the air volume, the blade damper 40 is particularly movably disposed between the air nozzle cover 20 and the air volume adjustment ring 30.

[0050] Each air volume adjustment blade 410 has a first fulcrum 411 at its end, which can be rotatably mounted on the air nozzle shell 10 of the air nozzle structure 100 with adjustable air volume, but is not limited to this, and can also be mounted on the air nozzle cover 20. Each air volume adjustment blade 410 has a second fulcrum 412 at its end, which can be rotatably mounted on the air volume adjustment ring 30.

[0051] Each air volume adjustment blade 410 is a long arc-shaped plate structure, and each air volume adjustment blade 410 may have an inner arc portion 413. When the air volume adjustment ring 30 rotates, the air volume adjustment ring 30 will synchronously drive each second fulcrum 412, and under the cooperation of the first fulcrum 411 moving within a certain range, each air volume adjustment blade 410 can move synchronously, thereby allowing the inner arc portions 413 to form a variable diameter air valve.

[0052] In addition, each air volume adjustment blade 410 has an outer arc portion 414 . Through the design of the outer arc portion 414 , the air volume adjustment blade 410 can be disposed in the accommodating space 210 in a more fitted and space-saving manner.

[0053] like Figure 7 As shown, during spraying or recovery of spray material, in order to effectively guide the airflow to the required position, the air nozzle structure 100 can adjust the air volume, which can further have an air guide nozzle 50, and the air guide nozzle 50 can be a polygonal structure, and the air guide nozzle 50 is connected to the second air port 220.

[0054] In actual applications, when performing spraying or recycling spray material operations, since the nozzle structure 100 with adjustable air volume can adjust the air volume individually, a multi-station configuration operation can be performed to allow the screws to undergo multiple stages of spraying, and each nozzle structure 100 with adjustable air volume can adjust and control the required air volume to match the desired spraying effect.

[0055] In addition, the bottom of the fixture for clamping the fastener is driven by a timing belt to rotate the fixture, so that the seat surface of the fastener can be evenly sprayed, and it can be used with a nozzle structure 100 with an adjustable air volume and a certain tilt angle to recover the powder after spraying, so that the powder is not easy to fall onto the head of the fastener and cause the head to stick to the material.

[0056] However, the above embodiments are used to illustrate the features of this embodiment, and their purpose is to enable those familiar with the technology to understand the content of the utility model and implement it accordingly, rather than to limit the patent scope of the utility model. Any other equivalent modifications or modifications that do not deviate from the spirit disclosed by the utility model should still be included in the scope of the patent application described above.
