The top of the liquid guide 2 is open to form a cavity for receiving the coating material. A filter 3 is provided below the liquid guide 2. A liquid infusion member 4 is installed between the bottom of the filter 3 and the liquid guide 2 to convey the coating material along a preset path. The discharge end of the liquid infusion member 4 is located above the filter 3.

[0031] The filter element 3 includes a shell unit and a filter unit. The two filter units are detachably screwed together and connected to the symmetrical two sides of the shell unit. A hose 38 is fixedly connected between the two filter units and the liquid guide member 2 on the side away from each other, and parts of the two filter units are both inside the shell unit. The liquid inlet end of the infusion member 4 is between the two filter units, and a valve 39 is installed on the hose 38.

[0032] Through the above technical solution, when personnel need to use the device, the device is installed below the coating roller (not shown in the figure) on the gravure coater, the paint is added to the liquid guide part 2, the coating roller is dipped into the paint, and then the paint is applied to the material to be coated, and the liquid guide part 2 receives the paint, and the paint is transported through the liquid guide part 2, the valve 39 on one hose 38 is opened, and the valve 39 on the other hose 38 is closed, so that the paint is transported to the hose 38, and the paint is transported through the hose 38 to the inside of the shell unit. When the paint enters the shell unit, the paint is filtered by the filter unit, and the filtered paint is transported to the infusion part 4, and the paint is transported back to the liquid guide part 2 through the infusion part 4. The above steps are repeated to recycle the paint. When personnel need to clean the filter unit, they close the valve 39 corresponding to the filter unit to be cleaned, rotate the filter unit, separate the filter unit from the shell unit, and then clean the filter unit.

[0033] Specifically, in one embodiment, regarding the liquid guide member 2:

[0034] like Figure 1-Figure 5 As shown, the liquid guide member 2 includes a bottom frame 21 , and the top of the bottom frame 21 is open to form a bottom cavity 23 .

[0035] In this embodiment, the paint is received by the bottom cavity 23 on the bottom frame 21 and transported through the bottom cavity 23 so that the paint is transported to the housing portion for use.

[0036] When the paint flows into the bottom cavity 23, in order to facilitate the paint to flow into the inside of the hose 38, as shown in FIG. Figure 5 As shown, the bottom of the bottom cavity 23 is inclined downward from both sides at the middle position to form a second slope 22 , and the level of the feeding end of the hose 38 is at the lowest level of the second slope 22 .

[0037] In this embodiment, when the paint is inside the bottom cavity 23, the second slope 22 cooperates to allow the paint to flow faster in the bottom cavity 23 to the hose 38 for transportation, thereby improving the paint transportation efficiency.

[0038] In addition, in the present invention, regarding the housing unit:

[0039] like Figure 1-Figure 5 As shown, the shell unit includes a bottom tube 31, which is open along its own axis to form an inner cavity 32, and a drain pipe 33 is fixedly connected to the bottom of the bottom tube 31. The two filter units are symmetrically screwed and connected to the symmetrical sides of the inner cavity 32, and the drain pipe 33 is located between the two filter units.

[0040] In this embodiment, the paint is transported through the hose 38 to the bottom tube 31. When the paint is transported to the bottom tube 31, the paint is filtered by the filtering unit, and the filtered paint is transported to the inside of the bottom tube 31. The filtered paint is transported through the drainage pipe 33 to the infusion piece 4, and the paint can be transported back to the device for use through the infusion piece 4.

[0041] Specifically, in one embodiment, regarding the above-mentioned filtering unit:

[0042] like Figure 1-Figure 5 and Figure 7-Figure 8 As shown, the filter unit includes a side cover 37, and the opposite sides of the two side covers 37 are fixedly connected to the connecting frame 36, and the opposite sides of the two connecting frames 36 are recessed to form a connecting groove 310, and the interior of the connecting groove 310 is screwed with a connecting ring 34, and the interior of the connecting ring 34 is fixedly connected to the filter screen 35.

[0043] In this embodiment, before filtering the paint, the connecting ring 34 is screwed together with the connecting frame 36, so that the connecting ring 34 is fixed to one side of the side cover 37, so that the filter 35 is fixed inside the inner cavity 32. When the filter 35 is fixed, the paint is transported to the inside of the inner cavity 32 through the hose 38. When the paint enters the inner cavity 32, the paint is filtered by the filter 35. The filtered filter 35 flows to the drain pipe 33, so that the paint is transported to the infusion part 4, and the paint can be transported back to the base frame 21 for recycling through the infusion part 4.

[0044] In order to facilitate the collection of excess coating left on the coating roller, such as Figure 1-Figure 4 and Figure 6 As shown, a liquid storage component 1 is fixedly connected to the top of the bottom frame 21 , and a liquid storage cavity 14 for storing liquid medicine is formed inside the liquid storage component 1 , and the liquid storage cavity 14 is communicated with the bottom cavity 23 .

[0045] In this embodiment, the liquid storage member 1 is supported by the bottom frame 21, the paint is received by the bottom cavity 23 at the top of the liquid storage member 1, and the paint is stored in the liquid storage cavity 14, so as to facilitate the recycling of the paint.

[0046] Specifically, in one embodiment, regarding the liquid storage element 1:

[0047] like Figure 1-Figure 4 and Figure 6 As shown, the liquid storage member 1 includes a liquid storage bucket 11 , and a liquid storage cavity 14 is formed inside the liquid storage bucket 11 .

[0048] In this embodiment, the paint is stored in the liquid storage chamber 14 on the liquid storage hopper 11 , and the paint is guided through the liquid storage chamber 14 so that the paint can be easily transported to the base frame 21 and then transported through the hose 38 .

[0049] In order to allow the paint in the liquid storage chamber 14 to be transported to the bottom chamber 23 more quickly, Figure 6 As shown, the liquid storage chamber 14 slopes downward from the inner wall to the middle position to form a first slope 15.

[0050] In this embodiment, when the paint is inside the liquid storage chamber 14, the first slope 15 cooperates to facilitate the paint to flow to the bottom of the liquid storage chamber 14, thereby increasing the paint flow rate and improving the paint circulation efficiency.

[0051] In order to expand the range of coatings received by the device, such as Figure 1-Figure 4 and Figure 6 As shown, a liquid collecting cover 12 is fixedly connected to the top of the liquid storage hopper 11 , and a liquid guiding cavity 13 is formed inside the liquid collecting cover 12 .

[0052] In this embodiment, when the coating roller drips paint, the paint is received by the liquid guide cavity 13 on the liquid collection cover 12, and the paint is guided by the liquid guide cavity 13 so that the paint flows into the liquid guide cavity 13 inside the liquid storage hopper 11, thereby completing the collection of the paint.

[0053] Specifically, in one embodiment, regarding the above-mentioned infusion device 4:

The feed end of the inlet pipe 42 is fixedly connected to the bottom of the discharge pipe 33, and the discharge end of the discharge pipe 43 is fixedly connected to one side of the liquid storage bucket 11.

[0055] In this embodiment, when the drain pipe 33 discharges the paint, the feed pump 41 works, so that the liquid inlet pipe 42 extracts the paint, and the paint is transported through the liquid outlet pipe 43, so that the paint is transported to the liquid storage bucket 11, thereby completing the circulation of the paint, making it easy to recycle the paint.

[0056] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
