Description

Technical Field

[0001] The invention relates to the technical field of ink color mixing, in particular to a cigarette box printing ink color mixing device. Background Art

[0002] Printing is the process of transferring text, pictures, photos, anti-counterfeiting and other originals to the printing substrate through printing machinery and special inks through processes such as plate making, inking, and pressurization.

[0003] In the printing industry, ink mixing and color matching are key links in ensuring the quality of printed products. Traditional mixing and color matching equipment usually uses a single stirring mechanism to mix the inks. Although this method can achieve uniform mixing of inks, due to the differences in ink batches (such as pigment dispersion and resin viscosity) and the lack of a pre-screening mechanism, mixing causes hue shift.

[0004] However, during actual use, the inventors found that when using a scraper fineness meter to perform a pre-screening test on the ink dispersion, bubbles are easily generated in the evenly stirred ink sample. During the scraping process, the bursting of bubbles or uneven scraping will cause the liquid film formed by the ink sample to be discontinuous, affecting the effect of the ink dispersion test.

[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1 like Figures 1-12 As shown, a cigarette box printing ink color mixing device includes a feeding mechanism 2, a carrying mechanism 3, a bubble elimination mechanism 4 and a scraping mechanism 5 arranged on a frame 1; The scraping mechanism 5 includes a scraping assembly 51 provided on the frame 1, a screed assembly 52 provided on the scraping assembly 51 and used to evenly spread the ink in front, and a cleaning assembly 53 provided on the scraping assembly 51; The scraping component 51 scrapes the ink on the fineness plate 6 to the end where the groove depth is zero. At the same time, the screed component 52 pushes the ink in front of the scraping component 51 back and forth evenly, and the ink forms a continuous liquid film. The cleaning component 53 cleans the residual ink on the scraping component 51.

[0034] It should be noted that in the process of printing ink color adjustment, due to differences in ink batches (such as dispersion and resin viscosity), mixed use will cause hue shift. Therefore, a pre-screening mechanism needs to be established.

[0035] In this embodiment, a scraper fineness meter is used to perform a pre-screening test on the dispersion of the ink to eliminate bubbles in the ink sample, and the ink sample in front of the scraper is pre-spread to prevent the liquid film formed by the ink sample from being fractured. The scraping sample is evenly spread, ensuring that the ink sample forms a continuous liquid film on the fineness plate, thereby improving the accuracy of the test.

[0036] Further, if Figure 1-Figure 2 As shown, the carrying mechanism 3 includes: A third driving unit 31 is provided on the frame 1 and includes a third screw rod 311 rotatably provided on the frame 1, a third threaded block 312 threadedly provided on the third screw rod 311, and a third stepping motor 313 provided on the frame 1 and used to drive the third screw rod 311; The carrier plate 32 is arranged on the third threaded block 312. The carrier plate 32 is provided with a plurality of positioning blocks 33. The positioning blocks 33 are used to limit the position of the fineness plate on the carrier plate 32. The third driving unit 31 drives the carrier plate 32 to move reciprocatingly horizontally.

[0037] In this embodiment, the carrying mechanism 3 is provided to carry the fineness plate for reciprocating horizontal movement, so that the fineness plate is transferred between the carrying mechanism 3, the bubble elimination mechanism 4, and the scraping mechanism 5, with stable carrying and precise positioning.

[0038] In detail, the fineness plate 6 is manually placed on the carrier plate 32, and the positioning block 33 limits the fineness plate. Then, the third stepper motor 313 drives the third threaded block 312 to move back and forth horizontally through the third screw rod 311. The third threaded block 312 drives the fineness plate to transfer between the three stations of the carrying mechanism 3, the bubble elimination mechanism 4, and the scraping mechanism 5 through the carrier plate 32. After the test is completed, the fineness plate is manually taken out for cleaning.

[0039] Further, if Figures 1-6 As shown, the unloading mechanism 2 includes a suction component 21 provided on the frame 1 and a bubble squeezing component 22 provided on the suction component 21 and used for squeezing bubbles in the ink; The suction assembly 21 includes: Sample boxes 211, several groups of the sample boxes 211 are arranged on the frame 1 and are used to store ink; A plurality of discharge heads 212 are mounted on the frame 1 via a mounting plate 213 and are connected to the sample boxes 211 via hoses. A pump is provided on the sample box 211 to pump the ink in the sample box 211 to the discharge heads 212. An inner cylinder 214 is rotatably disposed inside the blanking head 212, and an upper end thereof is connected to the hose; The outer ring 215 is provided at the upper end of the inner cylinder 214 , and the outer wall of the outer ring 215 is rotatably matched with the inner wall of the blanking head 212 .

[0040] It should be noted that three groups of sample boxes 211 and blanking heads 212 are used. The three groups of sample boxes 211 are filled with the same ink. The same sample is tested three times in parallel, and the average value is taken as the final result.

[0041] It should also be noted that when the discharge head 212 needs to be cleaned, the sample box 211 is brushed and filled with clean water, and the pump body sucks the clean water in the sample box 211 into the discharge head 212 for flushing.

[0042] In this embodiment, the material suction component 21 is provided to automatically discharge a quantitative ink sample to the end of the fineness plate groove (scale 0 end), and the ink sample flows smoothly.

[0043] In detail, the carrying mechanism 3 moves the fineness plate to the position below the discharge head 212 through the carrier plate 32, so that the discharge head 212 is opposite to the end of the fineness plate groove (scale 0 end), and then the pump body sucks the ink in the sample box 211 into the discharge head 212 in a quantitative manner, and the discharge head 212 discharges the ink sample at the end of the fineness plate groove (scale 0 end).

[0044] Further, if Figure 3-Figure 6 As shown, the bubble squeezing component 22 includes: A separation plate 221 is provided inside the inner cylinder 214 and has a mounting hole in the middle of the separation plate 221; The two groups of bubble squeezing rollers 222 are symmetrically arranged inside the mounting hole, and the two bubble squeezing rollers 222 rotate in opposite directions. The two bubble squeezing rollers 222 are respectively attached to the side walls of the mounting hole, and the gap between the two bubble squeezing rollers 222 is used to squeeze out bubbles in the ink; The first gear 223, two groups of the first gears 223 are symmetrically and rotatably arranged on the outer wall of the inner cylinder 214, and the two groups of the first gears 223 are respectively connected to one end of the two groups of the squeezing rollers 222 by a belt and a pulley. The belt and the pulley are both arranged in the inner cavity of the separation plate 221; A first gear ring 224 , which is fixedly disposed on the bottom of the blanking head 212 and is used to drive the two sets of first gears 223 to rotate synchronously; A second gear ring 225, the second gear ring 225 is fixedly disposed on the outer wall of the inner cylinder 214; The second gear 226 is rotatably disposed on the inner wall of the blanking head 212 and is used to drive the second gear ring 225 to rotate with the inner cylinder 214 . A driving motor 227 for driving the second gear 226 is provided on the mounting plate 213 .

[0045] It is worth mentioning that the tops of the two bubble squeezing rollers 222 are higher than the upper surface of the separation disk 221. During the self-rotation of the inner cylinder 214, the tops of the two bubble squeezing rollers 222 stir the ink sample in the inner cylinder 214, so that the bubbles in the ink sample gather toward the middle position of the inner cylinder 214 under the action of centrifugation, making it convenient for the two bubble squeezing rollers 222 to quickly squeeze out all the bubbles in the ink sample.

[0046] In this embodiment, by cooperating with the bubble squeezing component 22 and the suction component 21, on the one hand, during the process of the discharge head 212 discharges the ink sample, the inner cylinder 214 rotates, causing the two bubble squeezing rollers 222 on the separation disk 221 to rotate in opposite directions, driving the ink sample in the inner cylinder 214 to flow down from the gap between the two bubble squeezing rollers 222, and the two bubble squeezing rollers 222 squeeze the bubbles in the ink sample, thereby automatically eliminating the bubbles in the ink sample; on the other hand, during the self-rotation of the inner cylinder 214, the tops of the two bubble squeezing rollers 222 stir the ink sample in the inner cylinder 214, so that the bubbles in the ink sample gather toward the middle position of the inner cylinder 214 under the action of centrifugation, making it convenient for the two bubble squeezing rollers 222 to quickly squeeze all the bubbles in the ink sample.

[0047] In detail, the pump body sucks the ink in the sample box 211 into the discharge head 212 in a quantitative manner, and the ink sample enters the separation disk 221 in the inner cylinder 214. At the same time, the driving motor 227 drives the second gear ring 225 through the second gear 226 to rotate the inner cylinder 214. During the rotation of the inner cylinder 214, the first gear ring 224 drives the two groups of first gears 223 to rotate synchronously, so that the two groups of first gears 223 respectively drive the two groups of squeezing rollers 222 to rotate in opposite directions, so that the bubbles in the ink sample gather toward the middle position of the inner cylinder 214 under the action of centrifugation. At the same time, the two groups of squeezing rollers 222 drive the ink sample on the separation disk 221 to flow downward from the gap between the two groups of squeezing rollers 222. The two squeezing rollers 222 squeeze the bubbles in the ink sample. After the bubbles are eliminated, the ink sample drips from the lower port of the discharge head 212 to the end of the fineness plate groove (scale 0 end).

[0048] Further, if Figure 1-Figure 2 and Figure 7-Figure 9 As shown, the debubble mechanism 4 includes a debubble component 41 provided on the frame 1 and used to spread the ink on the fineness plate outward and squeeze out the bubbles, and a power component 42 provided on the debubble component 41; The defoaming component 41 includes: A mounting frame 411, the mounting frame 411 is arranged on the frame 1, and a hydraulic component 412 is arranged on the mounting frame 411; A hanging tube 413 is provided at the output end of the hydraulic component 412, and a vertical rod 414 is provided at the top of the hanging tube 413; A hollow tube 415 is sleeved on the vertical rod 414 , and a hanging ring 416 for hanging the hollow tube 415 is provided at the lower end of the vertical rod 414 ; A cover box 417 is rotatably mounted on the outer wall of the hollow tube 415 , and the diameter of the cover box 417 is equal to the groove width of the fineness plate; Defoaming rollers 418, two groups of defoaming rollers 418 are symmetrically and rotatably arranged at the lower end of the hollow tube 415, one end of each defoaming roller 418 is in contact with the inner wall of the cover box 417, and the bottom of each defoaming roller 418 is flush with the bottom of the cover box 417; The cleaning box 419 is arranged on the mounting frame 411 and is located directly below the cover box 417 , and is used to clean the ink remaining on the defoaming roller 418 and the cover box 417 .

[0049] It should be noted that the cleaning box 419 is filled with clean water, and the cover box 417 is lowered into the cleaning box 419 to clean the ink remaining on the defoaming roller 418 and the cover box 417.

[0050] It is worth mentioning that the cover box 417 and the defoaming roller 418 cooperate to spread out the ink sample discharged at the end of the groove of the fineness plate (the end of the scale 0), so that the ink sample is distributed in a circular shape in the groove. The circular boundary of the ink sample extends to the inner wall of the groove, which makes it convenient for the scraper 519 to start scraping the sample so that the liquid film formed by the ink sample can cover the entire groove.

[0051] Further, if Figure 8-Figure 9 As shown, the power assembly 42 is used to drive the hollow tube 415 to rotate with the defoaming roller 418 inside the cover box 417, which includes: A roller 421, the roller 421 is arranged on the outer wall of the hollow tube 415 through a fixing rod 422; The spiral track 423 is disposed on the inner wall of the hanging tube 413 and extends upward along the inner wall of the hanging tube 413 .

[0052] It should be noted that when the hollow tube 415 moves upward relative to the vertical rod 414, the roller 421 rolls upward in a spiral along the bottom of the spiral track 423, so that the roller 421 rotates with the hollow tube 415 through the fixed rod 422, and the hollow tube 415 drives the two defoaming rollers 418 to rotate. That is, after the cover box 417 and the defoaming roller 418 descend into the fineness plate groove, the two defoaming rollers 418 rotate along the circumferential direction in the groove, and the two defoaming rollers 418 spread the ink sample in the groove, squeeze the bubbles in the ink sample, and spread the ink sample outward along the circumferential direction.

[0053] In this embodiment, by cooperating with the provided defoaming component 41 and the power component 42, on the one hand, the ink sample in the groove of the fineness plate can be rolled and spread, and the bubbles in the ink sample can be squeezed out, thereby avoiding the appearance of blank spots on the liquid film formed by the bubbles in the ink sample; on the other hand, the ink sample can be flattened outward along the circumferential direction in the cover box 417, and the outer edge of the circular boundary of the ink sample extends to the inner wall of the groove, which facilitates the scraper 519 to scrape the sample evenly, and the liquid film formed by the ink sample can cover the entire groove, ensuring that the liquid film formed by the ink sample is continuous and complete.

[0054] In detail, the carrying mechanism 3 moves the fineness plate to the lower position of the bubble elimination mechanism 4 through the carrying plate 32, so that the ink sample at the end of the groove of the fineness plate (the end of the scale 0) is located directly below the cover box 417, and the hydraulic component 412 drives the hanging cylinder 413 to descend, so that the cover box 417 and the defoaming roller 418 descend into the groove of the fineness plate, and the cover box 417 covers the ink sample at the end of the groove (the end of the scale 0), and the hydraulic component 412 drives the hanging cylinder 413 to continue to descend, so that the hollow tube 415 moves upward relative to the vertical rod 414, and the roller 421 moves along the hanging cylinder 413. The bottom of the spiral track 423 on the inner wall spirally rolls upward, and the roller 421 rotates with the hollow tube 415 through the fixed rod 422. The hollow tube 415 drives the defoaming roller 418 to rotate twice. The defoaming roller 418 spreads the ink sample until the outer edge of the circular boundary of the ink sample reaches the inner wall of the groove. Then, the hydraulic component 412 drives the hanging cylinder 413 to rise and reset. Under the action of gravity, the hollow tube 415 moves downward relatively along the vertical rod 414 until the hollow tube 415 is reset. The cover box 417 and the defoaming roller 418 are separated from the fineness plate and rise and reset for next use.

[0055] Further, if Figure 1-Figure 2 and Figure 10-12 As shown, the scraping assembly 51 includes: A bracket 511 is provided on the frame 1. A first drive unit 512 is provided on the bracket 511. The first drive unit 512 includes a first screw rod 5121 rotatably provided on the bracket 511, a first threaded block 5122 threadedly provided on the first screw rod 5121, and a first stepper motor 5123 provided on the bracket 511 and used to drive the first screw rod 5121. The lug 513 is provided on the first threaded block 5122. A suspension rod 514 is provided, which is arranged on the hanging ear 513 and is lifted and lowered. The first driving unit 512 drives the suspension rod 514 to move back and forth horizontally. A contact 515 is provided at the upper end of the suspension rod 514. A first elastic member is provided between the contact 515 and the hanging ear 513. a first limiting rail 516 , which is disposed on the bracket 511 and is used to drive the boom 514 to descend; a lifting plate 517, the lifting plate 517 being sleeved and slidably disposed on the suspension rod 514, a fixed plate 518 being disposed at the lower end of the suspension rod 514, and a second elastic member being disposed between the lifting plate 517 and the fixed plate 518; The scraper 519 is provided on the lifting plate 517 and is adapted to the groove on the fineness plate.

[0056] It should be noted that after the first limiting track 516 drives the boom 514 to carry the scraper 519 down to the end of the fineness plate groove (scale 0 end), it continues to drive the boom 514 down, so that the fixed plate 518 at the lower end of the boom 514 stretches the second elastic member. Then, under the pulling force of the second elastic member, the second elastic member has a tendency to pull the scraper 519 downward through the lifting plate 517, ensuring that the scraper 519 is tightly against the bottom of the fineness plate groove to adapt to scraping grooves of different depths.

[0057] Further, if Figure 10-12 As shown, the screed assembly 52 includes: A second driving unit 521 is provided on top of the scraper 519 and includes a second screw rod 5211 rotatably provided on the scraper 519, a second threaded block 5212 threadedly provided on the second screw rod 5211, and a second stepping motor 5213 provided on the scraper 519 and used to drive the second screw rod 5211; An L-shaped vertical rod 522 , the L-shaped vertical rod 522 being disposed on the second threaded block 5212 ; The push plate 523 is provided at the lower end of the L-shaped vertical rod 522 , and the second driving unit 521 drives the push plate 523 to move reciprocatingly horizontally.

[0058] It should be noted that the bubble elimination mechanism 4 spreads the ink sample outward along the circumferential direction, and the ink sample is distributed in a circular shape at the end of the fineness plate groove (scale 0 end). After the scraper 519 scrapes the circularly distributed ink sample, there is more ink near the middle position in front of the scraper 519, and less ink on both sides. Therefore, the push plate 523 is required to scrape the ink in front of the scraper 519 evenly along the width direction of the groove to avoid the ink from forming a liquid film near the inner wall of the groove, and to ensure that the liquid film can continuously cover the groove.

[0059] In this embodiment, by cooperating with the scraping assembly 51 and the leveling assembly 52, on the one hand, the scraping work can be automatically completed, and the scraper 519 is tightly against the bottom of the fineness plate groove to adapt to grooves of different depths; on the other hand, in the process of scraping along the length direction of the groove, the push plate 523 spreads the ink in front of the scraper 519 evenly along the width direction of the groove, avoiding the ink from forming a liquid film near the inner wall of the groove, and scraping evenly to ensure that the liquid film can continuously cover the groove.

[0060] In detail, the carrying mechanism 3 moves the fineness plate to the lower position of the scraping assembly 51 through the carrying plate 32, so that the fineness plate groove is located directly below the scraper 519, and the first stepper motor 5123 drives the first threaded block 5122 to move the scraper 519 horizontally through the first screw rod 5121. The first limiting rail 516 drives the suspension rod 514 to lower the scraper 519 to the end of the fineness plate groove (scale 0 end), and then continues to drive the suspension rod 514 to descend, so that the fixed plate 518 at the lower end of the suspension rod 514 stretches the second elastic member, and then, under the pulling force of the second elastic member, the suspension rod 514 is pulled downward. The second elastic member has a tendency to pull the scraper 519 downward through the lifting plate 517. At the same time, the push plate 523 also drops into the fineness plate groove. The first drive unit 512 continues to drive the scraper 519 to move horizontally. At the same time, the second drive unit 521 drives the push plate 523 to move back and forth horizontally. The scraper 519 scrapes along the length direction of the groove. The push plate 523 spreads the ink in front of the scraper 519 evenly along the width direction of the groove. After the scraping is completed, the suspension rod 514 detaches from the first limiting track 516, and the suspension rod 514 rises and resets with the scraper 519 driven by the first elastic member.

[0065] In detail, the carrying mechanism 3 moves the fineness plate to the position below the visual inspection mechanism 7 through the carrying plate 32. The camera 71 collects the liquid film image information formed by the ink sample in the groove of the fineness plate, and transmits the liquid film image information to the existing image processing system to confirm the scale position where the continuous particle band appears for the first time, and detect the dispersion of the ink sample.

[0066] Working process: First, manually place the fineness plate 6 on the carrier plate 32, and the positioning block 33 limits the fineness plate. The carrying mechanism 3 moves the fineness plate to the position below the discharge head 212 through the carrier plate 32, so that the discharge head 212 is facing the end of the groove of the fineness plate (scale 0 end). Then, the pump body sucks the ink in the sample box 211 into the discharge head 212 in a quantitative manner. The discharge head 212 discharges the ink sample at the end of the groove of the fineness plate (scale 0 end). Then, the carrying mechanism 3 moves the fineness plate to the position below the bubble elimination mechanism 4 through the carrier plate 32, so that the end of the groove of the fineness plate (scale 0 end) is aligned with the end of the groove of the fineness plate. The ink sample at the end of the groove (scale 0 end) is located just below the cover box 417, the hydraulic component 412 drives the hanging cylinder 413 to descend, so that the cover box 417 and the defoaming roller 418 descend into the groove of the fineness plate, the cover box 417 covers the ink sample at the end of the groove (scale 0 end), and the defoaming roller 418 rolls the ink sample until the outer edge of the circular boundary of the ink sample reaches the inner wall of the groove. Then, the carrying mechanism 3 moves the fineness plate to the lower position of the scraping assembly 51 through the carrying plate 32, so that the fineness plate groove is located just below the scraper 519, and the first driving unit 512 drives the scraper The scraper 519 moves horizontally, and the first limiting rail 516 drives the boom 514 to lower the scraper 519 to the end of the fineness plate groove (scale 0 end). The first driving unit 512 continues to drive the scraper 519 to move horizontally. At the same time, the second driving unit 521 drives the push plate 523 to move back and forth horizontally. The scraper 519 scrapes along the length direction of the groove. The push plate 523 spreads the ink in front of the scraper 519 evenly along the width direction of the groove. After the scraping is completed, the first driving unit 512 continues to drive the scraper 519 to move horizontally, and the second limiting rail 532 drives The boom 514 lowers the scraper 519 and the push plate 523 into the cleaning box 531 to clean the ink remaining on the scraper 519 and the push plate 523. Finally, the carrying mechanism 3 moves the fineness plate to the lower position of the visual inspection mechanism 7 through the carrying plate 32. The camera 71 collects the liquid film image information formed by the ink sample in the groove of the fineness plate, and transmits the liquid film image information to the existing image processing system to confirm the scale position where the continuous particle band appears for the first time, and detect the dispersion of the ink sample. The same sample is tested in parallel three times, and the average value is taken as the final result.
