Description

Technical Field

[0001] The utility model relates to the technical field of ink coating, in particular to a coating device. Background Art

[0002] The coating process is based on the study of fluid properties. It is a process that applies one or more layers of liquid to a substrate, usually a flexible film or backing paper. The applied liquid coating is then dried in an oven or cured to form a film layer with special functions. However, the properties of the coating material itself have a significant impact on the coating effect. For example, poor dispersion of the coating material and agglomeration of the material will cause the coated film to have bad spots, seriously affecting the film quality. Therefore, before traditional coating, laboratory personnel are required to remove the coating liquid from the container, filter the coating liquid through a filter screen into another container, and then apply the coating. This process is complicated and can easily cause contamination of the coating liquid.

[0003] Therefore, there is an urgent need for a coating device that can quickly filter the coating liquid before coating, thereby removing large particles agglomerated in the coating liquid while ensuring simple and efficient operation. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0032] This embodiment provides a coating device, such as Figure 1 and Figure 2As shown, the coating device includes a container bottle 10, a spraying element 20, and a filter assembly 30. The container bottle 10 is used to hold the coating liquid; the spraying element 20 is connected to the container bottle 10, and the coating liquid can be sprayed from the spraying element 20; the filter assembly 30 is disposed between the spraying element 20 and the container bottle 10, and the coating liquid can pass through the filter assembly 30 and be sprayed from the spraying element 20. The filter assembly 30 is capable of filtering impurities in the coating liquid. In this device, the coating liquid in the container bottle 10 is filtered by the filter assembly 30 before being sprayed from the spraying element 20, thereby filtering out impurities and large agglomerated particles in the coating liquid, thereby ensuring the quality of the coating liquid and producing a good coating effect. In addition, the filtered coating liquid can be sprayed directly from the spraying element 20, ensuring ease of use.

[0033] It should be noted that in this embodiment, the coating liquid is ink. Long-term exposure to ink can easily lead to impurities or clumps, which can clog the spray element 20 and produce poor spraying results. The filter assembly 30 in this embodiment effectively solves this problem and is simple and convenient to operate. The container 10 can also be used to hold other liquids in other embodiments, and this embodiment does not limit its scope of use. Furthermore, the spray element 20 is a needle tube, which has a simple structure, is easy to manufacture, and offers high spraying precision and excellent spraying results.

[0034] like Figure 1 and Figure 2 As shown, the container bottle 10 includes a bottle body 11 and a bottle cap 12 that are interconnected. The bottle cap 12 is detachably connected to the bottle body 11, and the spraying member 20 is connected to the bottle cap 12. The spraying member 20, the bottle cap 12, and the bottle body 11 are sequentially connected to ensure that the coating liquid can be sprayed smoothly from the spraying member 20. The detachable connection between the bottle cap 12 and the bottle body 11 not only facilitates the timely replenishment of the coating liquid into the bottle body 11, but also facilitates subsequent maintenance and replacement.

[0035] It is worth noting that in this embodiment, the top of the bottle body 11 is provided with a bottle mouth 111, which is provided with an external thread, and the bottle cap 12 is provided with an internal thread. The bottle cap 12 is threadedly connected to the bottle mouth 111, which is convenient for installation and removal. In other embodiments, the connection can also be made by plugging or clamping, so as to facilitate assembly and disassembly.

[0036] To accelerate the spraying of the coating liquid from the spraying element 20, the bottle body 11 is made of a flexible material. Under the action of an external force, the bottle body 11 can elastically deform inward and squeeze the coating liquid, so that the coating liquid can be sprayed from the spraying element 20. In other words, during use, the operator can hold the bottle body 11 and, if the internal pressure is insufficient, squeeze the bottle body 11. At this time, the coating liquid inside the bottle body 11 can be smoothly sprayed from the spraying element 20, ensuring a good spraying effect. Because the bottle body 11 is elastically deformable, it can automatically return to its original shape after the external force is removed.

[0037] In addition, if Figure 1 and Figure 2 As shown, the diameter of the bottle cap 12 gradually decreases as it approaches the spray element 20. According to Bernoulli's principle, under the premise of constant flow rate, the smaller the diameter of the pipe through which the liquid flows, the greater the flow rate of the fluid. Therefore, this arrangement can further ensure the spraying speed of the coating liquid from the spray element 20, thereby producing a good spraying effect.

[0038] It is worth noting that, because different coating liquids require different storage methods, the material of the bottle body 11 can be selected based on the type of coating liquid. Specifically, if the coating liquid can be stored in light, the bottle body 11 can be made of a transparent material; if the coating liquid must be stored away from light, the bottle body 11 can be made of a light-shielding material, as long as the flexibility of the bottle body 11 is maintained. Furthermore, the material of the bottle body 11 and the spray element 20 should also be selected based on the type of coating liquid. For example, for coating liquids that react chemically with metals, neither the bottle body 11 nor the spray element 20 should be made of metal.

[0039] In addition, considering that the coating liquid may precipitate after long-term storage, a stirring member (not shown) is provided in the container 10, and the coating liquid can be stirred evenly by the stirring member before spraying, thereby producing a good spraying effect, thereby improving the yield rate of the product after spraying. In this embodiment, the stirring member is a magnetic stirring bar, which is resistant to high temperatures and chemical corrosion, has a stable speed regulation under the action of magnetic force, and has a good stirring effect.

[0040] To facilitate installation of the filter assembly 30, as Figure 2As shown, the filter assembly 30 includes a mounting member 31 and a filter member 32. The filter member 32 is mounted on the mounting member 31, and the mounting member 31 is detachably mounted within the bottle cap 12. It should be noted that the filter member 32 is a filter mesh, which is flexible and easy to place in various locations. However, its flexibility also creates the disadvantage of being immovable and fixed. By disposing the mounting member 31 within the bottle cap 12 and placing the filter member 32 on the mounting member 31, the problem of the filter mesh being difficult to install is solved. Furthermore, the mounting member 31 is not connected to the bottle cap 12. At the bottle mouth 111, the mounting member 31 can be abutted against the top of the bottle cap 12. When the bottle cap 12 is removed, the mounting member 31 can be directly removed, making it easier to replace the filter member 32 and the mounting member 31 and preventing them from clogging due to prolonged use.

[0041] To produce a good filtering effect, such as Figure 2 As shown, multiple filter elements 32 are provided along the axial direction of the container 10. This arrangement allows the coating liquid to be filtered multiple times before being sprayed from the spray element 20, thereby fully filtering out agglomerated particles and impurities in the coating liquid, thereby achieving a good spraying effect. In this embodiment, at least three filter screens are provided.

[0042] Furthermore, the mesh size of the multiple filters gradually increases as they approach the spray element 20. This arrangement allows for coarse filtration followed by fine filtration, thereby ensuring increasingly better filtration results. In this embodiment, the bottom filter layer has a 100-mesh size, the middle layer has a 300-mesh size, and the top layer has a 500-mesh size. In other embodiments, the mesh size of each filter layer can be adjusted according to actual needs; this embodiment does not impose a specific mesh size limit.

[0043] After the coating work is completed, a portion of the coating liquid may remain in the bottle body 11. For the convenience of storage, Figure 1 and Figure 2 As shown, the coating device also includes a sealing member 40, which can be used to block the end of the spraying member 20 away from the container 10. That is, after use, the sealing member 40 blocks the end of the needle tube that sprays the coating liquid, preventing the coating liquid from flowing out of the needle tube and preventing air from entering the coating liquid through the needle tube, thereby ensuring that the coating liquid can be stored for a long time. In this example, the sealing member 40 is a needle tube plug made of rubber material, which has a certain degree of flexibility and is easily mounted on the top of the needle tube.

[0044] In summary, the coating device of this embodiment can not only filter the coating liquid quickly before coating, but also remove large agglomerated particles in the coating liquid while ensuring simple and efficient operation.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
