[0005] In the above-mentioned decorative paper water-based ink mixing and stirring device, although the cleaning and maintenance of the tank body and the cleaning of the stirring mechanism are convenient, during the mixing and stirring of the ink, air may be introduced into the ink by the container surface, the stirrer, etc., and it is very likely that some raw materials in the ink are volatile. These components may evaporate during stirring, and then easily form bubbles in the container. These bubbles may have some impact on the quality of the ink and the subsequent printing effect. However, in the above-mentioned decorative paper decorative paper water-based ink mixing and stirring device, because the tank body is sealed by the box cover, it does not have the function of discharging bubbles, which is relatively inconvenient. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-Figure 5 An ink mixing mechanism for printing patterns on paper products comprises a mixing tank body 1 and a box cover 2 installed on the mixing tank body 1. A support tube 3 is fixedly connected to the surface of the box cover 2. The other end of the support tube 3 is fixedly connected to an exhaust tube 4, and the other end of the exhaust tube 4 is fixedly connected to a negative pressure pump 5. The outer wall of the negative pressure pump 5 is fixedly connected to the upper surface of the box cover 2. The support tube 3, the exhaust tube 4, the negative pressure pump 5 and the mixing tank body 1 are connected. The inner wall of the support tube 3 is connected to a filter assembly.

[0024] The ink mixing mechanism for printing patterns on paper products in the present invention is similar to the existing ink mixing mechanism, such as the water-based ink mixing and stirring device for decorative paper disclosed in the patent publication number CN217449973U. Figures 1 to 5As shown, when the ink mixing mechanism for printing patterns on paper products in the present invention mixes the ink for printing patterns on paper products through the mixing tank body 1, the raw materials of the ink required for printing the paper products are first uniformly put into the interior of the mixing tank body 1, and then the box cover 2 is buckled above the mixing tank body 1 to prevent external dust or other impurities from entering the interior of the mixing tank body 1. Then, the mixing tank body 1 is controlled by an external controller to stir and mix the internal ink raw materials. During the stirring and mixing period, some bubbles will inevitably be generated in the mixed ink. At this time, the switch of the negative pressure pump 5 is turned on by the external controller. After the negative pressure pump 5 is started, because the internal pressure of the mixing tank body 1 is high, these bubbles will accelerate to rise above the ink inside the mixing tank body 1, and enter the negative pressure pump 5 from the support tube 3 and the exhaust tube 4 above the mixing tank body 1, and finally be discharged from the exhaust end of the negative pressure pump 5, so that the gas in the bubbles can be discharged to the outside of the mixing tank body 1 more quickly.

[0025] What needs to be explained here is:

[0026] It is very likely that some raw materials in the ink will emit a certain degree of pungent odor. In order to prevent these gases from harming human health or damaging the negative pressure pump 5, when these gases are sucked out by the negative pressure pump 5, the gases will preferentially pass through the filter component in the support tube 3 and then be absorbed and filtered by the filter component, thereby preventing these pungent gases from being directly discharged into the external environment.

[0027] The external controller is a very mature technology at present, so it will not be described in detail.

[0028] The negative pressure pump 5 can be any common gas negative pressure pump, and the specific model is not limited.

[0029] Please refer to Figure 3-Figure 5 The filter assembly includes a filter tube 8, a cover ring 9 and two partition nets 10. The outer wall of the cover ring 9 is connected to the inner wall of the filter tube 8, the outer wall of the filter tube 8 is connected to the inner wall of the support tube 3, the outer walls of the two partition nets 10 are fixedly connected to the inner walls of the filter tube 8 and the cover ring 9 respectively, and the two partition nets 10 are respectively located at both ends of the filter tube 8.

[0030] More specifically, before installing the support tube 3, a filter material that can absorb odors (such as activated carbon, not limited to this specific method) can be loaded into the filter tube 8 between the two partitions 10. When the gas in the ink bubbles inside the mixing tank 1 enters the support tube 3, it will be preferentially absorbed by the adsorbent inside the filter tube 8 and then discharged from the exhaust pipe 4 above the support tube 3.

[0031] Please refer to Figure 4 and Figure 5A replacement port 301 is formed through the side wall of the support tube 3. A sealing plate 6 is slidably connected to the inner wall of the replacement port 301. The side of the sealing plate 6 closest to the support tube 3 is fixedly connected to the outer wall of the filter tube 8. The replacement port 301 allows the filter material inside the filter tube 8 to be cleaned or replaced during regular maintenance. The sealing provided by the sealing plate 6 prevents the leakage of these pungent gases from the replacement port 301 and prevents them from affecting the operation of the negative pressure pump 5.

[0032] Please refer to Figure 3-Figure 5 The sealing plate 6 is fixedly connected to the top and bottom of the connecting block 12. The replacement port 301 is provided with a slot 302 on the top and bottom. The outer walls of the two connecting blocks 12 match the slots 302 and are fastened together with bolts. By providing the connecting blocks 12 and the slots 302 and connecting them with bolts, the sealing plate 6 can be securely mounted on the support tube 3 without shaking or falling off.

[0033] Please refer to Figure 4 The upper surface of the sealing plate 6 is provided with a pressing groove 601, and a pressure strip 11 is slidably connected to the inner wall of the pressing groove 601. The side of the pressure strip 11 away from the sealing plate 6 is fixedly connected to the outer wall of the upper end of the cover ring 9, and the upper surface of the pressure strip 11 abuts against the inner wall of the replacement port 301. By providing the pressing groove 601 and the pressure strip 11, connecting the pressure strip 11 to the cover ring 9, and then abutting the pressure strip 11 against the replacement port 301, the pressure strip 11 can limit the cover ring 9, thereby preventing the filtered material inside the cover ring 9 and the filter tube 8 from flying upward when the negative pressure pump 5 is working, thereby preventing the cover ring 9 from falling off.

[0034] Please refer to Figure 1-Figure 5 The sealing plate 6 is fixedly connected to a handle 7 on one side away from the support tube 3. By arranging the handle 7, it is more convenient to grasp when the sealing plate 6 needs to be opened.

[0035] The outer wall of the lower end of the cover ring 9 is threadedly connected to the inner wall of the upper end of the filter tube 8. By arranging the cover ring 9 and the filter tube 8 to be threadedly connected, it is more convenient to separate the two when the filter material in the filter tube 8 needs to be replaced.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
