Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing technology, and in particular to an ultrasonic atomizing coating head. Background Technology

[0002] Currently known monochrome dyeing techniques primarily involve immersing the fabric in dye liquor. This method consumes a significant amount of water and dye and is prone to uneven dyeing due to incomplete dye agitation. To address these issues, the Chinese patent "Ultrasonic Atomizing Coating Head" (application number CN202210533932.7) uses an ultrasonic driver to atomize the dye liquor and utilizes airflow to propel the atomized dye liquor outward along a spray channel, ultimately depositing it onto the fabric to create a uniform dyeing effect. However, this patented technology involves directly spraying the atomized dye liquor outward through the spray channel, resulting in an uncontrolled spraying process and a lack of control over the dyeing process, thus presenting functional deficiencies.

[0003] In view of this, we propose an ultrasonic atomizing coating head to overcome the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The purpose of this invention is to provide an ultrasonic atomizing coating head to solve the problems existing in the prior art, and to control the spraying process of the atomized dye liquid.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-7 As shown, this utility model provides an ultrasonic atomizing coating head 100, including a housing, a filter 13, and an ultrasonic driver 3. The housing is provided with a cavity, a liquid inlet channel 5, an air inlet channel 7, and an outlet channel 11. The cavity is simultaneously connected to the liquid inlet channel 5, the air inlet channel 7, and the outlet channel 11. The cavity includes an air chamber 10, a liquid storage chamber 4, and an atomizing chamber 8. The ultrasonic driver 3 is fixed in the cavity. The housing includes an upper cover 1, a lower cover 2, and a gasket 9. The gasket 9 is sandwiched between the upper cover 1 and the lower cover 2. The upper cover 1, the lower cover 2, and the gasket 9 are detachably connected as a whole. The outlet channel 11 is formed by assembling the upper cover 1 and the lower cover 2. It also includes a nozzle plate 12, which is disposed in the outlet channel 11. The nozzle plate 12 is provided with a plurality of equally spaced nozzle holes 121.

[0037] In use, the ultrasonic atomizing coating head 100 allows liquid (i.e., dye solution) to enter the cavity through the liquid inlet channel 5 and cover the surface of the ultrasonic driver 3. The ultrasonic driver 3 generates high-frequency vibrations, atomizing the liquid on its surface into droplets. Simultaneously, gas enters the cavity through the gas inlet channel 7. The gas and the atomized droplets mix together to form a mist of dye, which is then sprayed outward through the nozzle holes 121 of the nozzle plate 12 and onto the fabric, achieving the dyeing function. This invention can control the uniformity and speed of liquid spraying, as well as the shape and size of droplets, by installing nozzle plates 12 with nozzle holes 121 of different shapes and / or sizes, thereby achieving the purpose of regulating the spraying process of the atomized dye solution.

[0038] As a specific embodiment of this utility model, the nozzle 121 is circular, elliptical, square, rhomboid, or star-shaped. However, its shape is not limited to the above shapes. In actual use, different shapes can be adopted according to the actual situation.

[0039] As a specific embodiment of this utility model, the nozzle plate 12 is a long strip plate, which is the same in shape and size as the spray channel 11.

[0040] As a specific embodiment of this utility model, the nozzle plate 12 is fixed to the housing by bolts, which facilitates disassembly and assembly.

[0041] In a specific embodiment of this utility model, the nozzle plate 12 is bonded to the housing by an adhesive.

[0042] As a specific embodiment of this utility model, the lower cover 2 is also provided with a liquid outlet channel 6, through which the liquid in the cavity can flow outward.

[0043] like Figures 8-9 As shown, in a specific embodiment of the present invention, the filter 13 is installed in the liquid storage chamber 4, and the liquid inlet channel 5 and the air inlet channel 7 are separated from the spray channel 11.

[0044] like Figures 10-11 As shown, in a specific embodiment of this utility model, the filter 13 is installed between the gasket 9 and the lower cover 2, and separates the liquid inlet channel 5 and the air inlet channel 7 from the spray channel 11.

[0045] The filter 13 can filter the incoming liquid and gas, preventing impurities from entering the nozzle plate 12 and clogging the nozzle 121, or from being sprayed out of the nozzle 121 and adhering to the fabric, thus affecting the printing and dyeing effect.

[0046] like Figures 12-13 As shown in the figure, in a specific embodiment of this utility model, the filter 13 is installed inside the spray channel 11 on the side near the cavity, and separates the liquid inlet channel 5 and the air inlet channel 7 from the nozzle plate 12. The filter 13 can not only perform the filtering function, but also optimize and stabilize the spray speed and uniformity of the liquid sprayed from the nozzle plate 12.

[0047] As a specific embodiment of this utility model, the filter 13 is fixedly connected to the housing by bolts, which facilitates disassembly and cleaning.

[0048] In a specific embodiment of this utility model, the filter 13 is bonded to the housing by an adhesive.

[0049] In a specific embodiment of this utility model, the filter 13 is a filter screen or a filter plate with filter holes. The shape of the filter holes in the filter 13 includes circular, square, rhomboid, or star-shaped. Different filtration effects can be achieved by installing filter holes of different shapes. The shape of the filter holes can be selected according to the actual situation.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
