[0025] To increase the ease of maintenance for ink mixing equipment, this invention provides a printing ink preparation process, comprising the following steps:

[0026] Step 1: Inject the finished inks of various colors into separate ink containers;

[0027] Step 2: The printing ink in the ink tank is added to the side surface of the color mixing roller 51 through the pigment injection tube 42;

[0028] Step 3: Place the lower side of the color mixing roller 51 against the color mixing disk 3, and control the color mixing roller 51 to move and rotate relative to the color mixing disk 3 to mix and spread the printing inks of multiple colors on the color mixing disk 3.

[0029] Step 4: Adjust the color of the printing ink adhering to the upper surface of the color matching palette 3 as needed.

[0030] The printing ink prepared using the printing ink preparation process of this application is obtained by mixing and color matching multiple finished inks of the same type.

[0031] The finished ink of this application comprises pigments, binders, fillers, diluents, and slip agents.

[0032] Many finished printing inks are of the same type, using the same kind of binders and additives, differing only in the use of pigments.

[0033] The following describes specific embodiments of the present invention.

[0034] Reference Figure 3-5 The illustration shows an embodiment in which a horizontally placed color matching disk 3 is used in the printing ink preparation process provided by the present invention, which increases the ease of maintenance of the ink color matching equipment and improves the color matching effect for different ink products with different flowability.

[0035] The color matching disk 3 of this application is placed on the transfer stand 1. A color matching device housing 2 is provided on the upper side of the transfer stand 1, and a color matching device body 4 is installed inside the color matching device housing 2.

[0036] The color matching roller 51 is rotatably installed inside the color matching device body 4, and the lower side of the color matching roller 51 can abut against the upper side of the color matching disk 3.

[0037] The horizontally placed color matching tray 3 holds finished ink products of various colors, making the flat color matching tray 3 easy to clean and increasing the convenience of maintenance for ink color matching equipment.

[0038] Meanwhile, the color matching palette 3 is set horizontally to limit the flow range of the finished ink, thereby improving the color matching effect for different finished inks with different flowability.

[0039] Reference Figure 3-4 The following is an embodiment illustrating the process of preparing printing ink provided by the present invention, which involves clamping the color matching disk 3 on the transfer stand 1 and increasing the color matching efficiency of the printing ink:

[0040] Two clamping arms 11 are symmetrically slidably mounted on the transfer stand 1 of this application, and one end of the clamping arm 11 can abut and fit against the side of the color matching disk 3.

[0041] A second telescopic actuator for driving the clamp arm 11 to slide is installed on the transfer stand 1;

[0042] Simultaneously, the second telescopic actuators on both sides are activated to extend and clamp the color matching disc 3 onto the transfer stand 1.

[0043] In addition, while keeping the color matching disk 3 clamped on the transfer stand 1, the second telescopic drivers on both sides are activated to extend and retract, changing the relative position of the color matching disk 3 and the color matching roller 51.

[0044] Furthermore, by controlling the color matching disk 3 to move back and forth slightly relative to the color matching roller 51, the color matching efficiency of the printing ink is increased.

[0045] Reference Figure 3 and Figure 5-7 The illustration shows an embodiment of the printing ink preparation process provided by the present invention, in which the finished ink of a specified color is added to the side surface of the color mixing roller 51 through the pigment injection tube 42, and then the color mixing roller 51 transfers it to the upper side of the color mixing disk 3:

[0046] This application uses multiple pigment injection tubes 42 to control the amount of each color of ink that has been injected, so as to facilitate quick color matching operations later.

[0047] Specifically: The pigment injection tube 42 is installed on the main body 4 of the color mixer. One end of the pigment injection tube 42 extends upward to the upper side of the color mixing roller 51, and the other end of the pigment injection tube 42 is connected to the ink tank through a pipe and a pump. The ink tank is fixedly connected inside the outer shell 2 of the color mixer.

[0048] Start the pump and add the finished ink of the specified color to the side surface of the color mixing roller 51 through the pigment injection pipe 42. During the subsequent rotation of the color mixing roller 51, the color mixing roller 51 contacts the upper side of the color mixing disk 3, completing the transfer operation of the finished ink of the specified color.

[0049] Reference Figure 3 The following is an illustration of a specific embodiment of controlling the movement and rotation of the color mixing roller 51 relative to the color mixing disk 3 in the printing ink preparation process provided by the present invention:

[0050] The transfer stand 1 of this application has a horizontal arm 13 mounted on its upper side. A rotating seat 14 is rotatably mounted on the end of the horizontal arm 13. A first rotation driver for driving the rotating seat 14 to rotate is mounted on the horizontal arm 13. The color matching device housing 2 is connected to the rotating seat 14 through a positioning block 22 mounted on its upper side.

[0051] The positioning block 22 is horizontally slidably connected to the rotating seat 14. A lead screw 15 is rotatably mounted on the rotating seat 14. The lead screw 15 is connected to the positioning block 22 by a threaded transmission. A second rotation driver for driving the lead screw 15 to rotate and a battery for powering the second rotation driver are mounted on the rotating seat 14.

[0052] The horizontal arm 13 is vertically slidably mounted on the L-shaped stand 12 on the top of the transfer stand 1. The L-shaped stand 12 is equipped with a telescopic driver for driving the horizontal arm 13 to move.

[0053] The rotary driver in this application can be a stepper motor or a servo motor;

[0054] The telescopic actuator of this application can be an electric telescopic rod or a hydraulic cylinder;

[0055] Start the first rotary driver to drive the rotating seat 14 to rotate, and control the color matching roller 51 on the color matching device to rotate relative to the color matching disk 3, so as to mix and spread the printing inks of multiple colors on the color matching disk 3.

[0056] Start the second rotary drive, and use the lead screw 15 to drive the positioning block 22 to move along the axis of the lead screw 15 on the rotating seat 14, thereby adjusting the distance between the edge of the color matching device and the rotation center of the rotating seat 14, thereby adjusting the size of the ink placement area on the color matching disk 3, so as to mix colors for a small batch of printing ink.

[0057] Start the telescopic driver to change the distance between the lower edge of the color matching roller 51 and the upper side of the color matching disk 3, and scrape and spread the ink during the subsequent movement and rotation of the color matching roller 51 relative to the color matching disk 3 in the control color matching device.

[0058] Reference Figure 6-7 The diagram illustrates the specific structure of the color matching device used in the printing ink preparation process provided by this invention, as well as embodiments that improve the control over the amount of printing ink used for each color and enhance the color matching efficiency and accuracy of mixed printing inks.

[0059] The color matching device body 4 of this application has a hollow semi-circular structure.

[0060] The inner sides of the color matching device body 4 are provided with arc-shaped slots at both ends. An elastic sheet 43 is installed between the arc-shaped slots on both sides. The elastic sheet 43 is slidably installed on the inner side of the color matching device body 4. The two ends of the elastic sheet 43 pass through both sides of the color matching device body 4. The ends of the elastic sheet 43 extend outward from the color matching device body 4. The two ends of the elastic sheet 43 are fixedly connected to two take-up rollers 44 respectively. The take-up rollers 44 are rotatably installed on the inner side of the sealing plate 21. A third rotation driver for driving the take-up rollers 44 to rotate is installed on the sealing plate 21.

[0061] Two third rotary drives are activated to control the two take-up rollers 44 to rotate synchronously in opposite directions. As the elastic sheet 43 slides within the color matching device body 4, the inner wall of the color matching device body 4 scrapes the lower surface of the elastic sheet 43. This allows the printing ink adhering to the inner surface of the elastic sheet 43 to drip onto the color matching disk 3 after being scraped, thereby increasing the control over the amount of printing ink used for each color and improving the efficiency and accuracy of color matching for mixing printing inks.

[0062] Reference Figure 5 , Figure 7 and Figure 9 The illustration shows an embodiment in which a hollow scraper edge 45 is added to the printing ink preparation process provided by the present invention to avoid excessive printing ink residue on the edges of both ends of the color matching roller 51, thereby improving the color matching effect of the printing ink:

[0063] A hollow scraper edge 45 is fixedly connected between the two disassembly seats II 41 of this application. The two ends of the color matching roller 51 are provided with inclined surfaces 53. The inner side of the hollow scraper edge 45 abuts against the inclined surface 53, and the inner side of the hollow scraper edge 45 abuts against the part of the side of the color matching roller 51 without the inclined surface 53.

[0064] The hollow scraper edge 45 is used to prevent excessive printing ink residue from remaining on the edges of both ends of the color matching roller 51, thereby improving the color matching effect of the printing ink.

[0065] Reference Figure 5-6 and Figure 8-9 The following embodiment illustrates an improvement in the ink preparation process provided by the present invention: It further enhances the ease of maintenance for ink color matching equipment and prevents residual finished inks of various colors from affecting the color matching of another batch of printing inks.

[0066] As a further improvement of this application, a sealing plate 21 is detachably and fixedly connected to the lower end of the color matching device housing 2. A disassembly seat I 23 is detachably and fixedly connected to the sealing plate 21. The color matching roller 51 is rotatably connected to the disassembly seat I 23. Disassembly seats II 41 are detachably and fixedly connected to both sides of the color matching device body 4. The color matching roller 51 is rotatably connected to the disassembly seat II 41.

[0067] A fourth rotary driver for driving the color matching roller 51 to rotate is installed on the sealing plate 21. A protrusion is welded to the output shaft of the fourth rotary driver, and the protrusion is inserted into the groove 52 at one end of the color matching roller 51.

[0068] Remove disassembly seat I 23 and disassembly seat II 41 from sealing plate 21 and color matching device body 4 respectively, and remove color matching roller 51 from color matching device body 4 in an inclined state;

[0069] During the process of removing the color matching roller 51, the disassembly seats I 23 and II 41 on both sides of the color matching roller 51 are removed together with the color matching roller 51, and the protrusions are separated from the grooves 52.

[0070] The above solution makes the color matching roller 51 easy to disassemble and clean, and facilitates equipment maintenance after the equipment uses finished inks of various colors to configure the colors of printing inks. It also avoids the impact of residual finished inks of various colors on the operation of configuring another batch of printing inks.
