Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a rotating nozzle for cleaning or drying. Background Art

[0002] During the production and manufacturing process of workpieces, the surface of the workpiece will need to be cleaned, such as dust removal, water removal, drying, etc. The rotary nozzle is an efficient, low-cost, easy-to-maintain cleaning equipment.

[0003] The prior art discloses a patent with a publication number of CN218190334U and a patent name of a rotating nozzle. Specifically, the patent discloses a nozzle housing and a double-helix rotating jet head, which is rotatably mounted inside the nozzle housing. Two spiral air passages are arranged inside the double-helix rotating jet head, one of which has an air outlet facing clockwise, and the other has an air outlet facing counterclockwise. When a compressed airflow enters from an air inlet of the nozzle housing, passes through the double-helix rotating jet head, and is finally discharged from an air outlet of the spiral air passage, the compressed airflow can drive the double-helix rotating jet head to rotate relative to the nozzle housing.

[0004] The above scheme has a simple structure, and the airflow can pass through two spiral air passages to achieve simultaneous air discharge in clockwise and counterclockwise directions, thereby driving the rotating jet head to rotate relative to the nozzle housing, so that the nozzle can blow out a rotating airflow to achieve multi-directional purge, a large purge area, and a good purge effect. There is no need to frequently change the direction of the nozzle, the operation is simple, and the purge efficiency is high.

[0005] However, since this solution uses two independent spiral channels to provide gas for rotational power, it not only requires two independent gas supply structures, but also has a complex internal structure. In order to ensure the sealing, the overall shell adopts an integrated design, which is not easy to disassemble and repair. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] The utility model is further described below in conjunction with embodiments.

[0044] Example:

[0045] See attached Figure 1-12 As shown, the present scheme proposes a rotating nozzle for cleaning or drying, which mainly includes two parts: an air inlet connector 1 and a rotating assembly 2. The air inlet connector 1 is connected to an air supply structure and a base (not shown in the figure), and a thread for fixing is provided at the outer end of the air inlet connector 1.

[0046] The rotating component 2 is rotatably set on the air intake connector 1. In this case, a sealed bearing is used to fix the rotating component 2 and the air intake connector 1. An air distribution hub 3 is set at the upper end of the rotating component 2, and the air intake connector 1 is connected to the air distribution hub 3 through an air duct 11.

[0047] The air channel 11 is divided into a first air channel 111 and a second air channel 112 in the air distribution hub 3. The first air channel 111 is arranged on the rotating component 2 and is used to provide the rotating component 2 with the power required for rotation, and the second air channel 112 is output as clean air.

[0048] Specifically, a cavity is provided inside the air distribution center 3, and in the present case, a working arm 4 is provided on each side of the air distribution center 3. The number of the working arms 4 can be adjusted according to actual needs, and each working arm 4 is communicated with the cavity. The second air duct 112 is connected to the output inside the working arm 4. When the gas flows out from the air duct 11 into the cavity, it will flow toward the working arms 4 on both sides to form the second air duct 112.

[0049] In this case, two nozzles 41 are detachably fixed on the end surface of the working arm 4 through a fixing seat 42, and the gas flowing out through the first air channel 111 will be sprayed out from the nozzles as cleaning and / or drying gas.

[0050] The nozzle 41 and the working arm 4 are fixed by screws, so that the convenience during disassembly and repair can be further improved.

[0051] Specifically, three spray holes 411 are provided on the nozzle 41, and a screw hole 412 matching the structure of the working arm 4 is provided on the rear side, a thread 421 matching the screw hole 412 is provided on the fixing seat 42, and a sealing ring groove 422 for ensuring the sealing effect is provided on the end face of the fixing seat 42.

[0052] The first air duct 111 also drains from the cavity. Specifically, in this case, an air chamber 21 is provided on the rotating component 2. There are two air chambers 21, and the inlet 111a of the first air duct 111 is located at the junction of the rotating component 2 and the cavity in the air distribution center 3, and is arranged on the rotating component 2. When the gas flows from the cavity, a part of the gas will enter the air chamber 21 from the inlet 111a, that is, the outlet of the first air duct 111 leads to the interior of the air chamber 21.

[0053] An end cover 22 is detachably provided at the outer end of the rotating component 2 by means of screws, one end of the end cover 22 extends into the air chamber 21, and an air outlet 221 is provided on the end cover 22 for communicating the air inside the air chamber 21 with the outside air, and the gas output from the first air passage 111 into the air chamber 21 will be discharged from the air outlet 221.

[0054] It is worth noting that in this case, two end covers 22 are provided, and the two end covers 22 are arranged circumferentially in the axial direction of the rotating component 2, and the air outlet directions are opposite, so that the two clockwise and counterclockwise opposite airflows are used to form the power to drive the rotating component 2 to rotate.

[0055] In order to further improve the performance of the nozzle, the rotating component 2 in this case also includes a speed control structure 23 for adjusting the speed of the rotating component 2.

[0056] Specifically, the speed control structure 23 includes a moving air core 231 disposed in the air chamber 21 , and the moving air core 231 is communicated with the air outlet 221 on the end cover 22 .

[0057] A cylindrical guide column 222 is provided in the middle of one end of the end cover 22 facing the interior of the rotating component 2, and an air flow cavity communicated with the air outlet 221 is provided in the middle of the guide column 222, and a cylindrical empty groove is provided at one end of the movable air core 231 facing the guide column 222. When the two cooperate, the movable air core 231 can be "sheathed" on the outer side of the guide column 222 for reciprocating movement.

[0058] A gas circulation chamber is also provided in the middle of the moving air core 231 , and the chamber is opened in the empty groove. Therefore, the chamber gas in the moving air core 231 can communicate with the air outlet 221 on the end cover 22 , that is, the gas flowing through the moving air core 231 can be discharged from the air outlet 221 .

[0059] The outlet of the first air channel 111 is located on the moving path of the moving air core 231 . When the moving air core 231 is staggered with the outlet of the first air channel 111 , the gas in the first air channel 111 is discharged from the air outlet 221 via the moving air core 231 .

[0060] The location of the outlet of the first air channel 111 is not specifically limited here. In this case, from a front view, the outlet of the first air channel 111 is arranged in a vertical direction of the moving air core 231 .

[0061] Specifically, a cylindrical protrusion 233 is vertically provided at the middle of one side end of the movable air core 231 away from the end cover 22, and the diameter of the protrusion 233 is smaller than the diameter of the movable air core 231, and a cylindrical cavity corresponding to the movement path of the protrusion 233 in the air chamber 21 begins, and the protrusion 233 can slide into the cavity when moving toward the side away from the end cover 22, and a vent 232 is provided at the upper end of the protrusion 233, and the outlet of the first air duct 111 is located on the moving path of the vent 232.

[0062] The vent 232 extends in a rectangular shape along the movement direction of the moving air core 231. When the vent 232 is misaligned with the outlet of the first air channel 111, the gas in the first air channel 111 can flow into the protrusion 233 through the outlet. The interior of the protrusion 233 is connected to the chamber in the moving air core 231, so that the gas can flow to the air outlet 221 through the moving air core 231.

[0063] The larger the area of ​​misalignment, the greater the air flow rate. When there is no misalignment, the air circulation between the two stagnates until misalignment occurs again.

[0064] Furthermore, in this case, an elastic member is arranged between the movable air core 231 and the end cover 22. The elastic member can adopt various elastic structures such as springs, springs 234, etc. In this case, spring 234 is used as the elastic member. The spring 234 is sleeved on the outer side of the guide column 222 and abuts against the groove surface of the movable air core 231.

[0065] When the gas flow rate distributed by the air distribution center 3 is large, more gas flows into the mobile air core 231 and outputs rotational power. Therefore, the rotation speed of the rotating component 2 gradually increases, thereby increasing the centrifugal force. Under the action of the centrifugal force, the mobile air core 231 begins to perform linear displacement. During the displacement process, the spring 234 is compressed and a certain elastic potential energy is accumulated. At the same time, the vent 232 gradually moves away from the outlet of the first air channel 111. Therefore, the offset area between the vent 232 and the outlet of the first air channel 111 gradually decreases, thereby reducing the amount of air input into the mobile air core 231. The centrifugal force will naturally decrease as well. Therefore, the rotation speed of the rotating component 2 decreases accordingly. Under the action of the elastic force, the mobile air core 231 rebounds. During the rebound process, the offset area between the vent 232 and the outlet of the first air channel 111 gradually increases. Therefore, a cycle of increasing and decreasing gas and increasing and decreasing rotation speed begins.

[0066] In this case, the outer cross-section of the moving air core 231 is smoothed to reduce friction during movement.

[0067] The outer end of the end cover 22 is provided with a sealing ring groove to ensure the sealing effect of the gas path.

[0068] To facilitate daily maintenance, the air distribution hub 3 is detachably connected to the rotating component 2 via a fixing 31. The fixing 31 includes a rod inserted into the air distribution hub 3 and spirally fixed to the end face of the rotating component 2. When maintenance is required, the fixing 31 can be removed to achieve the separation of the two.

[0069] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
