Description

Technical Field

[0001] The present application relates to the technical field of ink adhesion fastness detection equipment, and specifically to a device and method for detecting the adhesion fastness of gravure printing ink. Background Art

[0002] Gravure printing is to coat the entire surface of the printing plate with ink, then use a special scraper to remove the ink from the blank area, leaving only the ink in the cells of the image and text area. Then, under greater pressure, the ink is transferred to the surface of the substrate to obtain a printed product. Gravure printing is a direct printing method. The image part of the printing plate is concave, and the degree of concavity varies with the level of the image. The blank part of the printing plate is raised and on the same plane. The ink adhesion test for gravure printing is a key device for evaluating the quality of printed products. It is mainly used to quantify the adhesion performance of ink on the substrate surface. In the existing technology, the ink adhesion is usually tested by the tape stripping method. Specifically: Stick the standard tape on the printed surface and roll it (300 mm / min speed, 20 N ± 0.5 N pressure) to ensure full contact with the ink layer. After leaving it for 10 minutes, peel it off at a speed of 0.8 m / s. Quantify the results using the formula: Adhesion strength = Ink residual area / (Residual area + Detached area) (e.g., 96% indicates high adhesion). When using the tape stripping method to test the ink adhesion fastness, it is usually a manual operation, so the pasting, rolling, and placement and pressure holding are all controlled manually. For the test of a single sample, the above manual method has a small error. However, in batch operations, a large number of sampling inspections are required. Such a large number of repeated operations will inevitably produce errors, resulting in a lack of reliability in the measurement results. Therefore, it is necessary to provide a gravure printing ink adhesion fastness detection device and method to solve the above problems.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention 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, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] like Figure 1-Figure 2 As shown, the present application provides a device for testing the adhesion fastness of gravure printing ink, comprising a support mechanism 1, which is generally provided in the gravure printing testing process. The support mechanism 1 includes a support base 11 provided on the ground, a platen 12 fixedly mounted on the upper end of the support base 11, and a conveying mechanism 2 provided on the platen 12. The conveying mechanism 2 is used to convey samples (hereinafter referred to as sample 6) regularly produced during gravure printing to the adhesion fastness testing process; like Figure 1 and Figure 3As shown, the conveying mechanism 2 includes a plurality of brackets 21 fixedly mounted on the table 12, two sets of side plates 22 fixedly mounted on the brackets 21, a first motor 24 fixedly mounted at one end of one set of side plates 22, a first belt shaft (not shown in the figure) fixedly mounted at the output end of the first motor 24, the first belt shaft being mounted in bearings with the two sets of side plates 22, so that the first belt shaft is suitable for rotating under the drive of the first motor 24; At the same time, a second belt shaft (not shown) is installed on the bearing at the other end of the two sets of side plates 22. A belt 23 is installed between the second belt shaft and the first belt shaft, so that the belt 23 can be driven horizontally by the first motor 24. like Figure 3-Figure 4 As shown, multiple groups of mounting boxes 5 are evenly arranged at certain intervals on the belt 23, and mounting grooves 51 are provided inside the mounting boxes 5 for placing the samples 6; It is understood that the sample 6 has a fixed size and is adapted to the mounting groove 51, so that the sample 6 can be placed relatively tightly in the mounting groove 51 without shaking, and the thickness of the sample 6 is greater than the depth of the mounting groove 51, so that the upper surface of the sample 6 protrudes from the upper surface of the mounting box 5, so that the tape can be attached to the upper surface of the sample 6. like Figure 1 As shown, a pasting mechanism 3 is provided in the middle of the belt 23, and the pasting mechanism 3 is used to paste the tape onto the sample 6, and compact and maintain the pressure of the pasted tape; like Figure 6-Figure 9 As shown, the pasting mechanism 3 includes a pasting frame 31 provided on one side of the belt 23. A first stand 313 is fixedly mounted on one end of the pasting frame 31. A reel 35 is mounted on the upper end bearing of the first stand 313. A reel wheel 32 is fixedly mounted on the reel 35. An adhesive tape 34 is wound around the reel wheel 32. The adhesive tape 34 is a special adhesive tape for ink adhesion fastness testing. At the same time, a second stand 314 is fixedly installed at the other end of the pasting frame 31. A reel 36 is mounted on the upper end bearing of the second stand 314. A reel 33 is fixedly mounted on the reel 36. The reel 33 is used to wind up the adhesive tape 34 after use. A first tensioning roller 37 is rotatably provided on the pasting frame 31 and is located below the unwinding wheel 32. A second tensioning roller 38 is also rotatably provided on the pasting frame 31 and is located below the take-up wheel 33. Thus, the adhesive tape 34 can be unwound from the unwinding wheel 32, pass through the lower ends of the first tensioning roller 37 and the second tensioning roller 38, and finally be wound around the take-up wheel 33. It can be understood that the lower end of the adhesive tape 34 is the adhesive surface, while the upper end of the adhesive tape 34 is the adhesive backing surface, so that the adhesive backing surface of the adhesive tape 34 contacts the first tensioning roller 37 and the second tensioning roller 38, and thus does not stick to the first tensioning roller 37 and the second tensioning roller 38. In addition, the lower ends of the first tensioning roller 37 and the second tensioning roller 38 are higher than the upper surface of the sample 6 conveyed on the belt 23, so that the adhesive tape 34 with the adhesive surface facing downward can be easily adhered to the upper surface of the sample 6. In order to stick the tape 34 on the upper surface of the sample 6, as shown in FIG. Figure 4 、 Figure 6 and Figure 9 As shown, a pressure-boosting mechanism 7 is provided between the first tensioning roller 37 and the second tensioning roller 38. The pressure-boosting mechanism 7 can apply pressure to the adhesive tape 34 from the upper end to press the adhesive tape 34 downward and adhere it to the upper surface of the sample 6. The boosting mechanism 7 includes a boosting frame 71 fixedly mounted on the pasting frame 31, a cylinder 72 fixedly mounted on the boosting frame 71, and a connecting frame 73 fixedly mounted on the output end of the cylinder 72, so that the connecting frame 73 is suitable for reciprocating in the vertical direction under the drive of the cylinder 72; At the same time, two sets of rotating shafts 74 are fixedly installed on the connecting frame 73, and two sets of rotating frames 75 are rotatably installed on each set of rotating shafts 74. A booster roller 76 is rotatably installed on one end of the two sets of rotating frames 75 away from the rotating shafts 74, and a torsion spring 77 is fixedly installed between the rotating frame 75 and the rotating shaft 74; In the initial state, the two sets of boosting rollers 76 are both located at the upper end of the tape 34 and do not contact the adhesive backing surface of the tape 34. At the same time, the two sets of boosting rollers 76 are in a position close to each other under the action of the torsion spring 77. It can be understood that at this time, the two sets of boosting rollers 76 are both located in the middle of the rotating frame 75 and slightly inclined to the sides, and present an outward-facing "eight" shape; When the two sets of booster rollers 76 are driven by the cylinder 72, they will move vertically downward synchronously and contact the adhesive surface of the tape 34. At this time, the contact position between the booster rollers 76 and the tape 34 is exactly at the center of the sample 6. Then, the tape 34 will move downward synchronously with the booster rollers 76 and contact the center of the sample 6. When the tape 34 comes into contact with the sample 6, it will stick to the upper surface of the sample 6. At this time, the two sets of booster rollers 76 will be resisted by the sample 6 and cannot continue to move vertically downward. Therefore, the two sets of booster rollers 76 will roll from the center of the sample 6 to the two ends of the sample 6 under the action of the resistance. During the rolling process of the two sets of pressure rollers 76, the adhesive tape 34 is smoothly adhered to the upper surface of the sample 6. When the stroke of the cylinder 72 reaches the limit, the two sets of pressure rollers 76 are located at both ends of the sample 6 and tightly press against the surface of the adhesive tape 34 to maintain the pressure of the adhesive tape 34. After maintaining the pressure for a period of time, the cylinder 72 begins to reset, and under the action of the torsion spring 77, the two sets of pressure rollers 76 move from the two ends of the sample 6 to the middle position of the sample 6 until the two sets of pressure rollers 76 move closer to each other. As the cylinder 72 continues to reset, the two sets of pressure rollers 76 continue to move upward and return to their initial positions to facilitate the next application and pressure maintenance of the adhesive tape 34 .

[0023] It should be noted that when the booster roller 76 pushes the tape 34 downward, the tape 34 detaches from the unwinding wheel 32 and the rewinding wheel 33 synchronously and symmetrically, and drives the unwinding wheel 32 and the rewinding wheel 33 to rotate, thereby pressing the tape 34 to the upper surface of the sample 6.

[0024] In order to remove the tape 34 from the upper surface of the sample 6 for subsequent adhesion fastness testing, as shown in FIG. Figure 6-Figure 7 As shown, a second motor 39 is fixedly mounted at the lower end of the pasting frame 31, and a second pulley 311 is fixedly mounted at the output end of the second motor 39. At the same time, a first pulley 310 is fixedly mounted on the reel-up shaft 36. A driving belt 312 is provided between the first pulley 310 and the second pulley 311, so that the first pulley 310 can rotate under the drive of the second motor 39, thereby synchronously driving the reel-up wheel 33 to reel the adhesive tape 34, so as to transmit the tested adhesive tape 34. It can be understood that after the tape 34 is adhered to the surface of the sample 6 and maintained under pressure, the winding wheel 33 begins to wind up the tape 34. At this time, the tape 34 will slowly detach from the sample 6 and be wound on the winding wheel 33, thereby removing the tested tape 34 from the upper surface of the sample 6.

[0025] Because the take-up wheel 33 is connected to the second motor 39, the rotation of the take-up wheel 33 is controlled by the second motor 39, so that the tape 34 on the take-up wheel 33 will not be detached due to the pressure of the boosting roller 76, and the boosting roller 76 can only drive the tape 34 on the unwinding wheel 32 to detach, which affects the adhesion of the tape 34 to the sample 6; In order to solve the above problems, Figure 6 and Figure 8 As shown, a sliding mechanism 9 is provided on the pasting frame 31. Specifically, the sliding mechanism 9 includes a sliding frame 93 fixedly mounted on the pasting frame 31. A horizontally arranged slide rail 94 is fixedly mounted on the sliding frame 93. A slide plate 92 is slidably mounted on the slide rail 94. The second tensioning roller 38 is mounted on the slide plate 92 via a bearing, so that the second tensioning roller 38 can move horizontally along with the slide plate 92. At the same time, a gas spring 91 is fixedly installed on the pasting frame 31, and the output end of the gas spring 91 is fixedly installed with the slide plate 92; In the initial state, the slide plate 92 is located at the right side of the slide rail 94 under the action of the gas spring 91 ( Figure 6 Perspective), when the booster roller 76 presses the tape 34 downward, it drives the second tensioning roller 38 to move to the left to accommodate the downward movement of the tape 34; When the test is completed and the pressure roller 76 is separated from the tape, the second tensioning roller 38 will move to the right under the action of the gas spring 91 and simultaneously peel the tape 34 from the sample 6. Subsequently, the winding wheel 33 only needs to be wound and tensioned.

[0026] In order to adjust the position of the pasting frame 31 so as to adapt to the test of the sample 6 at different positions, Figure 6-Figure 7 and Figure 10 As shown, an adjustment mechanism 8 is provided on the table 12, and the adjustment mechanism 8 includes a base 81 fixedly mounted on the table 12, an adjustment rail 82 fixedly mounted on the base 81, and an adjustment seat 83 slidably provided on the adjustment rail 82. The pasting frame 31 is fixedly mounted on the adjustment seat 83, so that the pasting frame 31 can move along the adjustment seat 83 on the adjustment rail 82 to approach or move away from the sample 6; At the same time, a side frame 86 is fixedly mounted on the table 12, and a screw rod (not shown in the figure) is threadedly mounted on the side frame 86. A nut 88 is provided on the screw rod for transmission. The nut 88 is fixedly mounted on the pasting frame 31, so that the pasting frame 31 can be driven to move along the direction of the adjustment rail 82 by rotating the screw rod. A knob 87 is provided at one end of the screw rod to facilitate the rotation of the screw rod by the staff. In order to fix the pasting rack 31, a side seat 84 is fixedly mounted on the right side of the base 81. A handle 85 is threadedly mounted on the side seat 84. The handle 85 is suitable for rotating on the side seat 84 to abut against the adjustment seat 83, thereby limiting the movement of the pasting rack 31. In summary, when the position of the pasting rack 31 needs to be adjusted, it is only necessary to rotate the knob 87. When the pasting rack 31 is adjusted to a suitable position, the pasting rack 31 can be locked by the handle 85 to keep the pasting rack 31 stable.

[0027] In order to test the sample 6 after gluing to evaluate the ink adhesion fastness of the sample 6, as shown in the following figure: Figure 1 and Figure 5 As shown, a detection mechanism 4 is provided on the table 12, and the detection mechanism 4 includes a detection frame 41 fixedly mounted on the table 12, a detection box 42 fixedly mounted on the detection frame 41, and a camera 43 installed inside the detection box 42, so that the glued sample 6 is driven by the conveying mechanism 2 to reach directly under the camera 43, and the adhesion status of the ink on the surface of the sample 6 is collected by the camera 43, and then the ink adhesion fastness of the sample 6 is evaluated.

[0028] This application also provides a gravure printing ink adhesion fastness test, which is specifically divided into the following steps: In the first step, the sample 6 is placed in the mounting groove 51 on the mounting box 5, and then driven by the conveying mechanism 2 to the testing station; The second step is to use the adjustment mechanism 8 to adjust the position of the pasting mechanism 3 so that the sample 6 is located directly below the tape; In the third step, the pressure-increasing mechanism 7 is used to press the tape against the upper surface of the sample 6, and the pressure-increasing roller 76 is used to pressurize the tape so that the tape is adhered tightly. In the fourth step, the pressurizing mechanism 7 is reset, and the tape is peeled off from the sample 6 by rewinding the tape; In the fifth step, the conveying mechanism 2 conveys the pasted sample 6 to the position of the detection mechanism 4, and then uses the camera 43 to collect the adhesion status of the ink on the surface of the sample 6 to evaluate the ink adhesion fastness of the sample 6.

[0029] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
