Description

Technical Field

[0001] This utility model relates to the field of printing testing technology, specifically to an ink abrasion resistance tester. Background Technology

[0002] As described in the published patent "Ink Friction Testing Device" with publication number CN218003143U, the ink printing abrasion tester is used to test the abrasion resistance of the ink layer of printed matter, the abrasion resistance of the photosensitive layer of PS plate, and the abrasion resistance of the surface coating of related products. It can effectively analyze problems such as poor abrasion resistance of printed matter, ink film peeling, low printing durability of PS plate, and poor coating hardness of other products.

[0003] The ink printing abrasion resistance tester mainly includes a sample stage, a friction head, and a power unit. The sample stage is used to mount the paper to be tested. The friction head is located above the paper to be tested, and the friction medium on it keeps in contact with the surface of the paper. The drive rod of the power unit drives the friction head to reciprocate on the surface of the paper, thereby achieving the purpose of testing.

[0004] The operation process of the ink printing abrasion resistance tester is as follows: First, fix the sample to be tested on the sample stage, then fix the dry or wet standard friction paper on the friction head, and then rotate the speed control knob to the required speed so that the friction head presses against the sample and rubs the sample surface back and forth with a certain pressure, friction stroke and speed to determine the contamination level of the friction paper and the degree of fuzzing or wear on the sample surface. This effectively analyzes problems such as poor abrasion resistance of printed materials, ink layer peeling, low printing durability of PS plates and poor coating hardness of other products.

[0005] As described in the published patent CN116754419B, "A Paper Box Ink Abrasion Resistance Testing Device and Testing Method Thereof," paper packaging printing products mostly appear in the form of containers, and paper containers are diverse, including packaging boxes made of whiteboard paper, strawboard paper, and corrugated cardboard. In paper box printing, selecting good inks and good processing techniques can greatly improve printing quality and enhance the grade of the paper boxes. Ink adhesion is one of the important parameters for judging the quality of ink. When testing the abrasion resistance of paper box inks, the operator fixes the paperboard to be tested, printed with ink, on a testing table. A reciprocating drive mechanism drives a friction paper to repeatedly rub the paperboard. When the rubbing time reaches a preset value, the operator removes the friction paper and judges the abrasion resistance of the ink by observing the ink on the friction paper. However, the pressure of the friction paper pressing on the paperboard is constant. In actual use, the force of the object rubbing against the ink is not constant. Existing ink abrasion resistance testing devices are not convenient for simulating the movement scenario of ink under repeated rubbing at different forces, and therefore have certain limitations.

[0006] In summary, during the production of printed materials, it is necessary to test the abrasion resistance of paper box inks. However, the relevant technologies for ink abrasion resistance testing devices have limitations, as they are not convenient for simulating the motion of ink under repeated friction at different forces.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 An ink abrasion resistance tester includes a base 101, on which a positioning component 102 and a friction component 103 are mounted; like Figure 1 and 2As shown, firstly, the ink abrasion resistance tester of this utility model achieves "stable dynamic control" of friction pressure. This is specifically achieved through the synergistic effect of the lifting adjustment block 107 and the locking part 109: the operator can adjust the height of the lifting adjustment block 107 arbitrarily within the axial range of the mounting column 106 by simply turning the locking part 109, thereby accurately setting the vertical pressure of the friction head 113 acting on the surface of the printed matter. This adjustment is not only continuous and stepless, capable of simulating an infinite number of pressure scenarios from slight contact to heavy extrusion, but also ensures that the lifting adjustment block 107 will not shift during the high-speed reciprocating motion of the motor part 110 through the strong friction force generated by the threaded locking, thus ensuring constant pressure during the test. The positioning component 102 includes a positioning seat 104 fixedly mounted on the base 101, and a positioning plate kit 105 for positioning printed matter is mounted on the upper end of the positioning seat 104. The friction assembly 103 includes a mounting post 106 fixedly mounted on a base 101. The mounting post 106 is equipped with a lifting adjustment block 107 that can slide up and down. The side wall of the lifting adjustment block 107 is provided with a threaded locking hole 108. A locking element 109 is screwed into the threaded locking hole 108. The locking element 109 is adjustablely locked to the side wall of the mounting post 106. A motor component 110 is fixedly mounted on the lifting adjustment block 107, and a mounting plate 112 is fixedly mounted on the output shaft of the motor component 110. A friction head 113 for friction testing with printed matter is fixedly mounted on the lower end face of the mounting plate 112. Secondly, this design enhances the "reliability" of the test. In real transportation, handling, or use, the friction and pressure on the surface of the packaging box are not constant. This device can flexibly set various pressure parameters for comparative testing, thereby more comprehensively evaluating the abrasion resistance of ink under different harsh conditions. For example, it can simulate the friction of express packaging under stacking and squeezing (high pressure), or the friction of frequent picking and putting on retail shelves (low pressure, high frequency), so that the test results are no longer limited to a single laboratory condition, but can more accurately predict the performance of the product in complex real-world environments. Furthermore, the design embodies a high degree of "ease of operation." The pressure adjustment mechanism is simple and intuitive, and can be completed quickly without complicated tools, improving testing efficiency and facilitating rapid iterative quality control inspection. At the same time, the plate kit design of the positioning component 102 and the reciprocating motion driven by the motor ensure the stability of the sample clamping and the standardization of the friction process, enabling the tester to adapt to the testing needs of different substrates and different printing coatings, from thin cardboard to thick corrugated cardboard. Only the pressure needs to be adjusted, without the need to replace the core components, demonstrating good versatility. This utility model ink abrasion resistance tester works in concert with a positioning component 102 and a friction component 103 on a base 101. The positioning component 102 uses a positioning seat 104 and a positioning plate kit 105 to stably fix the printed material, while the friction component 103 cooperates with a locking component 109 through a lifting adjustment block 107 on a mounting column 106 and its threaded locking hole 108 on its side wall, thereby flexibly adjusting the height of the lifting adjustment block 107 and locking it in place, thus flexibly controlling the pressure of the friction head 113 on the printed material. The motor component 110 drives the mounting plate 112 and the friction head 113 to reciprocate, simulating repeated friction operations. The friction pressure can be easily changed by adjusting the lifting adjustment block 107, effectively simulating the friction scenarios of ink under different forces, overcoming the limitations of the prior art, and improving the applicability of the test.

[0020] In this embodiment of the utility model, the front end face of the mounting column 106 is provided with a snap-fit ​​groove 114 along the vertical direction, and snap-fit ​​teeth 115 are evenly arrayed along the length direction in the snap-fit ​​groove 114. The lifting adjustment block 107 is provided with a snap-fit ​​mounting hole 116, and an elastic element 117 and a snap-fit ​​element 118 are installed in the snap-fit ​​mounting hole 116. The snap-fit ​​element 118 is engaged with the snap-fit ​​teeth 115. One end of the elastic element 117 is engaged with the inner bottom surface of the snap-fit ​​mounting hole 116, and the other end of the elastic element 117 is engaged with the snap-fit ​​element 118. like Figure 1 , 4 As shown in Figure 5, the lifting adjustment block 107 is positioned in a gear-like manner by engaging with the buckle 118 and the buckle teeth 115 at different positions. The elastic element 117 continuously provides clamping force to ensure a stable engagement, enabling quantitative control of the pressure adjustment of the friction head 113 on the printed material. Each buckle tooth 115 position corresponds to a specific pressure value, which not only reduces the reading error and loosening risk that may exist in the adjustment process of the lifting adjustment block 107, but also greatly improves the repeatability of pressure setting and operational efficiency, thereby ensuring the consistency and reliability of test data. In one embodiment, scale marks matching the teeth 115 are provided on both sides of the locking groove 114, which can better quantify the adjustment of the lifting block 107.

[0021] In this embodiment of the utility model, a sleeve connecting rod 119 is fixedly installed on the output shaft of the motor component 110, a sleeve connecting member 120 is detachably installed on the sleeve connecting rod 119, a threaded adjusting rod 121 is fixedly installed at the lower end of the sleeve connecting member 120, a threaded adjusting hole 122 is opened on the mounting plate 112, and the mounting plate 112 is screwed into the threaded adjusting rod 121 through the threaded adjusting hole 122; like Figure 1 and 6As shown, a sleeve connecting rod 119 is provided on the output shaft of the motor component 110, and a threaded adjusting rod 121 is connected through a detachable sleeve connecting piece 120, so that the mounting plate 112 forms a screw connection with the threaded adjusting rod 121 through the threaded adjusting hole 122. The mounting plate 112 can be installed and removed from the threaded adjusting rod 121 by screwing it on. At the same time, the detachable connection between the sleeve connecting rod 119 and the sleeve connecting piece 120 enables the rapid disassembly and assembly of the entire transmission component, realizing the modular and rapid replacement of the friction head 113 and its mounting plate 112. This not only easily adapts to friction heads 113 of different specifications and materials to expand the testing range, but also simplifies the maintenance and replacement process, significantly improving testing efficiency.

[0022] In this embodiment of the utility model, the left and right side walls of the mounting column 106 are respectively provided with a left sliding groove 123 and a right sliding groove 124, and the two sides of the lifting adjustment block 107 are respectively formed with sliding snap blocks 125 that slide and engage in the left sliding groove 123 and the right sliding groove 124. like Figure 1 and 2 As shown, the sliding engagement of the sliding block 125 within the left slide groove 123 and the right slide groove 124 provides vertical guidance and radial constraint for the lifting movement of the lifting adjustment block 107, eliminating any possible shaking or deflection of the lifting adjustment block 107 during adjustment and operation. This ensures that the friction head 113 remains perpendicular to the surface of the printed material being tested, thus improving the stability of the pressure adjustment and friction test process.

[0023] In this embodiment of the utility model, fastening nuts 126 are respectively installed on the upper and lower end faces of the mounting plate 112, and the fastening nuts 126 are screwed onto the threaded adjusting rod 121; like Figure 2 and 3 As shown, by screwing fastening nuts 126 onto the upper and lower end faces of the mounting plate 112, the mounting plate 112 is firmly clamped and fixed at a specific position on the threaded adjusting rod 121. The double locking structure formed by the two fastening nuts 126 effectively prevents relative rotation or axial movement between the mounting plate 112 and the threaded adjusting rod 121 due to vibrations caused by the reciprocating motion of the motor, thereby enhancing the stability and reliability of the friction head 113 installation and ensuring the constant transmission of friction test pressure and the consistency of the motion trajectory. As shown in the figure, in one embodiment, in order to avoid interference between the friction head 113 and the fastening nut 126, the height of the friction head 113 is set to be greater than that of the fastening nut 126.

[0024] In this embodiment of the utility model, the positioning plate kit 105 includes a positioning connecting rod 127 fixed to the upper end face of the positioning seat 104. The upper end face of the positioning connecting rod 127 is detachably equipped with a positioning sleeve 128. The upper end of the positioning sleeve 128 is fixedly equipped with a positioning support plate 129. The positioning support plate 129 is fixedly equipped with a positioning base plate 130 by bolts. like Figure 6 As shown, a modular assembly structure is formed by the positioning connecting rod 127 fixed to the positioning seat 104, the detachable positioning sleeve 128, and the positioning support plate 129. Each component is installed step by step through detachable connection, realizing flexible combination and quick assembly and disassembly of the height of the positioning base plate 130 and the support structure. The height of the positioning base plate 130 can be flexibly adjusted by replacing the positioning sleeve 128 and the positioning support plate 129 of different specifications, thereby adapting to the testing needs of printed materials of different thicknesses or types, enhancing the versatility of the equipment, and facilitating the replacement of the positioning base plate 130 according to different specifications of printed materials.

[0025] In this embodiment of the present invention, a slide rail assembly 131 and a support block 132 are mounted on the positioning base plate 130. The slide rail assembly 131 is fixedly mounted on the positioning base plate 130. A positioning working plate 134 is mounted on the slider 133 of the slide rail assembly 131. One end of the positioning working plate 134 is fixedly connected to the slider 133, and the other end of the positioning working plate 134 is supported on the support block 132. The lower end face of the support block 132 is locked to the positioning base plate 130. A plurality of bolt docking holes are evenly opened along the length direction on the upper end face of the support block 132. The positioning working plate 134 is provided with bolt locking holes 136 that are locked to the bolt docking holes. like Figure 6 and 7 As shown, by setting a slide rail assembly 131 and a support block 132 with multiple sets of bolt docking holes on the positioning base plate 130, one end of the positioning work plate 134 is fixed to the slider, and the other end is locked with the selected bolt docking hole on the support block 132 through the bolt locking hole 136. The horizontal position of the positioning work plate 134 can be flexibly adjusted by the slide rail assembly 131 and the positioning is achieved by bolt locking. At the same time, by selecting different bolt docking holes to adjust the position of the positioning work plate 134, the horizontal position of the test sample can be quickly adjusted. Friction tests on different parts of the printed material can be completed without re-clamping the sample, which significantly improves the testing efficiency and ensures the positioning stability of each test.

[0026] In this embodiment of the utility model, a positioning mounting groove 137 is provided on the positioning working plate 134, and a limiting post 138 is fixed at the four corners of the positioning mounting groove 137. like Figure 2As shown, a positioning mounting groove 137 is opened on the positioning work plate 134 and a limiting post 138 is fixed at its four corners; the printed sample to be tested is quickly positioned and confined within the predetermined area of ​​the positioning mounting groove 137, which effectively prevents the sample from sliding or shifting during the test and improves the clamping efficiency.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
