The present invention sets an electric heating furnace, so that before using the ink pressing plate to press the ink, the electric heating furnace is started in advance, so that the electric heating furnace heats the inside of the heat-insulating outer barrel through the heating rod, and then heats the mixing barrel, and the heat-insulating outer barrel is used to keep the mixing barrel warm, so that the ink inside the mixing barrel has higher fluidity after being heated, thereby improving the mixing degree of the ink and preventing the low-temperature ink from being difficult to mix evenly due to poor fluidity; 4.

[0019] like Figures 1 to 9 As shown, a printing ink mixing device with a purification function includes a mixing barrel 1, as shown in FIG. Figure 2As shown, an ink inlet tube 2 connected to the inside of the mixing barrel 1 is fixedly installed on one side of the mixing barrel 1, and an ink outlet tube 3 connected to the inside of the mixing barrel 1 is fixedly installed on the bottom of the mixing barrel 1. Figure 3 As shown, a vertically arranged hydraulic lifting rod 4 is fixedly installed on the top inner wall of the mixing barrel 1, and an ink pressing plate 5 is fixedly installed on the telescopic end of the hydraulic lifting rod 4 facing downward. Figure 4 As shown, a plurality of vertically arranged pressure relief ink holes 501 are provided on the top of the ink pressing plate 5, and the plurality of pressure relief ink holes 501 are evenly distributed along the axis of the ink pressing plate 5, as shown in FIG. Figure 3 As shown, a plurality of evenly distributed circulating ink tubes 6 are fixedly installed on the side wall of the mixing barrel 1, and both ends of the circulating ink tubes 6 are connected to the interior of the mixing barrel 1. In this embodiment, the circulating ink tubes 6 are C-shaped structures, and both ends thereof are passed into the interior of the mixing barrel 1. The top of the circulating ink tubes 6 is located in the middle of the mixing barrel 1, and the bottom of the circulating ink tubes 6 is located at the bottom of the mixing barrel 1. When the hydraulic lifting rod 4 is in a retracted state, the ink pressing plate 5 is in the highest position. At this time, the top of the circulating ink tubes 6 is located above the ink pressing plate 5. An air delivery pipe 7 connected to the interior of the mixing barrel 1 is fixedly installed on one side of the top of the mixing barrel 1. Figure 1As shown, a filter box 8 is provided on one side of the mixing barrel 1, one end of the air supply pipe 7 is connected to the interior of the filter box 8, and an exhaust pipe 9 is provided on one side of the filter box 8. In this embodiment, an air pump is provided inside the filter box 8 to provide a power source for the absorption of VOC; specifically, when the printing ink mixing device is in use, the ink materials to be mixed and prepared are sequentially transported to the interior of the mixing barrel 1 through the ink inlet pipe 2 to wait for mixing, and the ink pressing plate 5 is provided so that after the ink materials are input into the mixing barrel 1, the hydraulic lifting rod 4 starts to drive the ink pressing plate 5 to press down. When the ink pressing plate 5 contacts the ink materials, the pressurized ink materials will be squeezed upward through the pressure relief ink hole 501 on the ink pressing plate 5. As the ink pressing plate 5 is gradually pressed down, the ink materials that cannot flow upward through the pressure relief ink hole 501 will flow through the inlets of the circulating ink tubes 6 at the bottom of the mixing barrel 1, that is, the bottom end of the circulating ink tube 6, to the top end of the circulating ink tube 6 under the action of pressure, until they flow back to the mixing barrel 1 from the opening at the top end of the circulating ink tube 6. Inside, the ink originally at the bottom is circulated to the top, and then the ink pressing plate 5 is reset to make the ink flow down, and the ink pressing plate 5 is repeatedly moved to make the ink flow up and down alternately, so as to realize the circulating flow mixing of the ink, so that the ink is mixed evenly, and a large amount of VOC can be released at the same time, so that the VOC is transported to the filter box 8 through the air supply pipe 7 at the top for filtration, and finally discharged through the exhaust pipe 9, thereby greatly reducing the amount of VOC released during the subsequent use of the ink, and playing a role in purifying the ink. By setting the pressure relief ink hole 501, the pressure relief ink hole 501 can not only make the ink flow from the bottom of the ink pressing plate 5 to the top of the ink pressing plate 5 under the action of pressure, but also make the ink have two surging directions of surging along the multiple circulating ink tubes 6 on the circumferential side and along the pressure relief ink hole 501 in the middle, so that the ink mixing is more even, but also can play a role in pressure relief, increase the channel for the ink to flow up and down, and prevent the ink from failing to flow up in time and causing excessive pressure inside the mixing barrel 1.

[0020] like Figure 1 As shown, the outside of the mixing barrel 1 is fixedly sleeved with an insulation outer barrel 10, and the bottom of the insulation outer barrel 10 is fixedly installed with an electric heating furnace 11. Figure 2 As shown, a plurality of heating rods 12 are fixedly installed on the top of the electric heating furnace 11, and the plurality of heating rods 12 extend to the interior of the heat-insulating outer barrel 10. In the present embodiment, electromagnetic control valves are arranged on the ink inlet tube 2 and the ink outlet tube 3, and the ink inlet tube 2 and the ink outlet tube 3 respectively penetrate the heat-insulating outer barrel 10 and communicate with the interior of the mixing barrel 1. Specifically, by arranging the electric heating furnace 11, before the ink is pressed by the ink pressing plate 5, the electric heating furnace 11 is started in advance, so that the electric heating furnace 11 heats the interior of the heat-insulating outer barrel 10 through the heating rods 12, and then heats the mixing barrel 1. The heat-insulating outer barrel 10 is used to keep the mixing barrel 1 warm, so that the ink inside the mixing barrel 1 has higher fluidity after being heated, thereby improving the mixing degree of the ink and preventing the low-temperature ink from being difficult to mix evenly due to poor fluidity.

[0021] like Figure 2 As shown, a heat-conducting barrel rack 13 is fixedly sleeved on the bottom of the mixing barrel 1, and a heat-conducting tube rack 14 is fixedly sleeved on the circulating ink tubes 6. The heat-conducting tube racks 14 are fixedly connected to the heat-conducting barrel rack 13, and the heating rods 12 are connected to the heat-conducting barrel rack 13. Specifically, by arranging the heat-conducting barrel rack 13 and the heat-conducting tube rack 14, when the electric furnace 11 heats the inside of the heat-insulating outer barrel 10 through the heating rods 12, the heat-conducting barrel rack 13 connected to the heating rods 12 will conduct the heat to the surrounding side of the bottom of the mixing barrel 1, thereby increasing the heating speed of the mixing barrel 1 and improving the uniformity of heating of the mixing barrel 1. At the same time, the heat-conducting barrel rack 13 will conduct the heat to each heat-conducting tube rack 14, so that each circulating ink tube 6 can also be heated evenly, thereby improving the fluidity of the ink in the circulating ink tube 6.

[0022] like Figure 4 As shown, a central control shaft 15 arranged vertically is rotatably installed at the axial position of the ink pressing plate 5, the bottom end of the central control shaft 15 extends to the bottom of the ink pressing plate 5 and is fixedly installed with a large stirring blade assembly 16, a sealed housing 17 is fixedly installed on the top of the ink pressing plate 5, a stirring motor 18 is fixedly installed inside the sealed housing 17, a transmission chamber is arranged inside the ink pressing plate 5, the output shaft of the stirring motor 18 extends to the inside of the transmission chamber and is fixedly sleeved with a control gear 19, a driven large gear 20 is fixedly sleeved on the central control shaft 15, and the control gear 19 is meshed with the driven large gear 20; specifically, by setting the large stirring blade assembly 16, while the ink plate 5 presses the ink up and down, the stirring motor 18 will drive the meshed driven large gear 20 to rotate through the control gear 19, and then drive the large stirring blade assembly 16 at the bottom of the ink plate 5 to rotate at high speed through the central control shaft 15, so that the large stirring blade assembly 16 stirs the ink at the bottom of the ink plate 5, thereby increasing the surging direction of the ink, quickly eliminating the stratification phenomenon of the ink, and making the ink mixed more evenly.

[0023] like Figure 4 As shown, a plurality of evenly distributed side control shafts 21 are rotatably installed inside the transmission chamber, and the side control shafts 21 are vertically arranged and fixedly sleeved with driven pinions 23, and the driven pinions 23 are meshed with the driven large gears 20. The top ends of the side control shafts 21 extend to the top of the ink press plate 5 and are fixedly installed with small stirring blade assemblies 22. Specifically, by arranging the small stirring blade assembly 22, when the stirring motor 18 drives the large stirring blade assembly 16 to rotate, the driven large gear 20 will drive each side control shaft 21 to rotate synchronously through each meshing driven pinion 23, thereby driving each small stirring blade assembly 22 to rotate at high speed on the top of the ink press plate 5, so that the ink on the top of the ink press plate 5 will also be stirred and mixed more evenly.

[0024] like Figure 6 As shown, a folded mesh tube 24 is fixedly installed at one end of the gas delivery pipe 7, and the folded mesh tube 24 is located inside the filter box 8, as shown in FIG. Figure 5 , Figure 7 As shown, an activated carbon mesh box 28 is placed inside the filter box 8, and a sealing box plate 29 is provided on one side of the activated carbon mesh box 28. Figure 8 As shown, locking plates 30 are fixedly installed on both sides of the activated carbon net box 28, hanging rings 32 are fixedly installed on both sides of the sealing box plate 29, and locking screws 31 are fixedly installed on one side of the locking plate 30. One end of the locking screw 31 at the same place passes through the hanging ring 32 and is screwed with a locking nut 33. Figure 1 As shown, a magnetic sealing door 34 is rotatably installed on one side of the filter box 8; specifically, by setting a folding mesh tube 24, the VOC released by the ink mixture is transported to the inside of the filter box 8 through the gas pipe 7 and the folding mesh tube 24, and will gradually be adsorbed by the activated carbon particles inside the activated carbon net box 28. The folding structure of the folding mesh tube 24 can increase the contact area between the gas and the activated carbon particles, prolong the adsorption time, and improve the adsorption effect. When the adsorption performance of the activated carbon decreases, the magnetic sealing door 34 can be opened and the activated carbon net box 28 can be taken out, the locking nuts 33 on both sides can be unscrewed, the sealing box plate 29 can be opened and the activated carbon particles inside the activated carbon net box 28 can be replaced, thereby ensuring that the adsorption performance of the activated carbon net box 28 and the filter box 8 meets the use requirements.

[0025] like Fig. 9 As shown, a mesh tube slot 2801 is provided on the side of the activated carbon mesh box 28 facing away from the sealing box plate 29, and the folded mesh tube 24 is located inside the mesh tube slot 2801. In the present embodiment, the mesh tube slot 2801 is a slot recessed into the inside of the activated carbon mesh box 28, and the activated carbon mesh box 28 as a whole is a rigid mesh plate; specifically, by setting the mesh tube slot 2801, after the activated carbon mesh box 28 is placed in the filter box 8, the folded mesh tube 24 will just be inserted into the mesh tube slot 2801 on one side of the activated carbon mesh box 28, so that the folded mesh tube 24 is located inside the mesh tube slot 2801, and when the folded mesh tube 24 releases gas containing VOC, the gas will be released inside the activated carbon mesh box 28, thereby greatly increasing the contact area between the gas and the activated carbon particles, and further improving the adsorption effect on VOC.

[0026] like Figure 6As shown, an outlet pipe 25 connected to the inside of the filter box 8 is fixedly installed on one side of the filter box 8, a three-way control valve 26 is fixedly installed on one end of the outlet pipe 25, the exhaust pipe 9 is fixedly installed on one end of the three-way control valve 26, and a circulation pipe 27 is fixedly installed on the other end of the three-way control valve 26, and one end of the circulation pipe 27 is connected to the gas supply pipe 7; specifically, by setting the circulation pipe 27, the gas input into the filter box 8 is initially adsorbed and filtered, and then re-input into the gas supply pipe 7 through the three-way control valve 26 and the circulation pipe 27 for secondary circulation filtration. After multiple filtrations, the three-way control valve 26 controls the exhaust pipe 9 to be connected, and the gas will be discharged through the exhaust pipe 9 at this time, thereby improving the adsorption of VOCs by increasing the number of filtration times and improving the purification effect on ink.

[0027] In summary, when the ink mixing device for printing is in use, the ink materials that need to be mixed and mixed are sequentially transported to the inside of the mixing barrel 1 through the ink inlet pipe 2 to wait for mixing. By setting the ink pressing plate 5, after the ink materials are input into the mixing barrel 1, the hydraulic lifting rod 4 starts to drive the ink pressing plate 5 to press down. When the ink pressing plate 5 contacts the ink materials, the pressurized ink materials will be squeezed upward through the pressure relief ink hole 501 on the ink pressing plate 5. As the ink pressing plate 5 is gradually pressed down, the ink materials that fail to flow upward through the pressure relief ink hole 501 will flow through the inlets of the circulating ink tubes 6 at the bottom of the mixing barrel 1, that is, the bottom end of the circulating ink tube 6, to the top end of the circulating ink tube 6 under the action of pressure, until they flow back to the inside of the mixing barrel 1 from the opening at the top end of the circulating ink tube 6, so that the ink materials originally at the bottom circulate to the top, and then the ink pressing plate 5 is reset. , so that the ink flows downward, and the ink pressing plate 5 is repeatedly moved to make the ink flow up and down alternately, so as to realize the circulating and surging mixing of the ink. While making the ink mixed evenly, a large amount of VOC can be released, so that the VOC is transported to the filter box 8 through the air supply pipe 7 at the top for filtration, and finally discharged through the exhaust pipe 9, thereby greatly reducing the amount of VOC released during the subsequent use of the ink, and playing a role in purifying the ink. By setting the pressure relief ink hole 501, the pressure relief ink hole 501 can not only make the ink flow from the bottom of the ink pressing plate 5 to the top of the ink pressing plate 5 under the action of pressure, but also make the ink have two surging directions of surging along the multiple circulating ink tubes 6 on the circumferential side and surging along the pressure relief ink hole 501 in the middle, so that the ink mixing is more even, and it can also play a role in pressure relief, increasing The channel for the ink to surge up and down prevents the ink from failing to surge up in time and causing excessive pressure inside the mixing barrel 1. By setting the electric heating furnace 11, before using the ink pressing plate 5 to press the ink, the electric heating furnace 11 is started in advance, so that the electric heating furnace 11 heats the inside of the heat-insulating outer barrel 10 through the heating rod 12, and then heats the mixing barrel 1, and uses the heat-insulating outer barrel 10 to insulate the mixing barrel 1, so that the ink inside the mixing barrel 1 has higher fluidity after being heated, thereby improving the mixing degree of the ink, and preventing the low-temperature ink from being difficult to mix evenly due to poor fluidity. By setting the heat-conducting barrel rack 13 and the heat-conducting pipe rack 14, when the electric heating furnace 11 heats the inside of the heat-insulating outer barrel 10 through the heating rod 12, the heat-conducting barrel rack 13 connected to the heating rod 12 will heat the inner part of the heat-insulating outer barrel 10. The heat is transferred to the surrounding side of the bottom of the mixing barrel 1, thereby increasing the speed of heating the mixing barrel 1 and improving the uniformity of heating the mixing barrel 1. At the same time, the heat-conducting barrel rack 13 transfers the heat to each heat-conducting tube rack 14, so that each circulating ink tube 6 can also be heated evenly, thereby improving the fluidity of the ink in the circulating ink tube 6. By setting the large stirring blade assembly 16, while the ink pressing plate 5 presses the ink up and down, the stirring motor 18 drives the meshing driven large gear 20 to rotate through the control gear 19, and then drives the large stirring blade assembly 16 at the bottom of the ink pressing plate 5 to rotate at a high speed through the central control shaft 15, so that the large stirring blade assembly 16 stirs the ink at the bottom of the ink pressing plate 5, thereby increasing the surging direction of the ink, quickly eliminating the stratification phenomenon of the ink, and making the ink mixed more evenly.By setting the small stirring blade assembly 22, when the stirring motor 18 drives the large stirring blade assembly 16 to rotate, the driven large gear 20 will drive the side control shafts 21 to rotate synchronously through the meshing driven small gears 23, thereby driving the small stirring blade assemblies 22 to rotate at high speed on the top of the ink pressing plate 5, so that the ink on the top of the ink pressing plate 5 will also be stirred and mixed more evenly. By setting the folding mesh tube 24, the VOC released by the ink mixture will be transported to the inside of the filter box 8 through the gas supply pipe 7 and the folding mesh tube 24, and will gradually be adsorbed by the activated carbon particles inside the activated carbon net box 28. The folding structure of the folding mesh tube 24 can increase the contact area between the gas and the activated carbon particles, prolong the adsorption time, and improve the adsorption effect. When the adsorption performance of the activated carbon decreases, the magnetic sealing door 34 can be opened and the activated carbon net box 28 can be taken out, the locking nuts 33 on both sides can be unscrewed, the sealing box plate 29 can be opened, and the activated carbon particles inside the activated carbon net box 28 can be replaced, so as to To ensure that the adsorption performance of the activated carbon mesh box 28 and the filter box 8 meets the use requirements, the mesh pipe slot 2801 is set, so that after the activated carbon mesh box 28 is placed in the filter box 8, the folded mesh pipe 24 will be just inserted into the mesh pipe slot 2801 on one side of the activated carbon mesh box 28, so that the folded mesh pipe 24 is located inside the mesh pipe slot 2801. When the folded mesh pipe 24 releases the gas containing VOC, the gas will be released inside the activated carbon mesh box 28, thereby greatly increasing the contact area between the gas and the activated carbon particles, and further improving the adsorption effect of VOC. By setting the circulation pipe 27, the gas input into the filter box 8 is initially adsorbed and filtered, and then re-input into the gas supply pipe 7 through the three-way control valve 26 and the circulation pipe 27 for secondary circulation filtration. After multiple filtrations, the three-way control valve 26 controls the exhaust pipe 9 to be connected, and the gas will be discharged through the exhaust pipe 9 at this time, thereby improving the adsorption of VOC by increasing the number of filtration times and improving the purification effect of ink.
