Description

Technical Field

[0001] The utility model relates to the technical field related to ink research and development testing, and in particular to a novel ink wear resistance testing device. Background Art

[0002] During the use of a printing substrate coated with ink, the ink pattern on the substrate must maintain high adhesion. That is, the ink pattern must not easily fall off the substrate during use, thereby affecting the aesthetics of the printed pattern. Therefore, when developing inks, it is necessary to test the abrasion resistance of the ink on the substrate. Currently, the abrasion resistance of inks is tested using an abrasion tester. Before using the abrasion tester, the target friction parameter value for the abrasion resistance test must be pre-set on the abrasion tester. The printing substrate is then placed in the abrasion tester for abrasion resistance testing.

[0003] The abrasion tester can only test the wear resistance of the printing substrate under a certain fixed friction value. However, in practice, the printing substrate printed with ink is also faced with the use scenario of being scratched. When scratched, the friction between the printing substrate and the contact object is in a linear growth state. Even in the use scenario of repeated scratching back and forth, the friction between the printing substrate and the contact object is in a linear and repeated change state. However, when the abrasion tester is currently used to test the wear resistance of the printing substrate, it is still unable to truly restore the use scenario of the printing substrate being scratched or even repeatedly scratched, and it is unable to test the wear resistance of the printing substrate when the friction force is in a linear growth or linear and repeated change. To this end, we have proposed a new ink wear resistance test device. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0018] Combined with attachment Figure 1 and attached Figure 2 As shown, a new type of ink wear resistance testing device includes a test bench 10, a pressure sensor 20, and a robotic arm 50. The upper end of the pressure sensor 20 is fixedly connected to the test bench 10, and the lower end of the pressure sensor 20 is fixedly installed on the fixed base 30. The test bench 10 includes a bracket 11 and a table 12. The table 12 is fixed on the bracket 11. The left and right sides of the table 12 are provided with a clamping mechanism 40 for fixing the printing substrate on the table 12. The clamping mechanisms 40 on the left and right sides of the table 12 are specifically arranged relative to each other.

[0019] The robotic arm 50 is a conventional four-axis manipulator equipped with a lifting rod 51, which is equipped with a clamping rod rolling mechanism 52 for clamping a rubber rod 60. The robotic arm 50 gradually adjusts the height of the rubber rod 60, driving it to roll back and forth across the surface of the printing substrate. The friction force of the rubber rod 60 can be linearly adjusted directly by the robotic arm 50, realistically recreating the use scenario of the printing substrate being scratched, even repeatedly. This allows testing the wear resistance of the printing substrate under linearly increasing or linearly changing friction forces, providing a more comprehensive test of the wear resistance of the ink.

[0020] Combined with attachment Figure 1 and attached Figure 3As shown, the clamping mechanism 40 includes an articulated frame 41, a locking rod 42, a follower 43, and a clamping member 44. The articulated frame 41 is fixedly mounted on the table 12. A first hinge shaft 411 and a second hinge shaft 412 are respectively provided on the front and rear sides of the articulated frame 41. The locking rod 42 is provided through the first hinge shaft 411 and is threadedly connected to the first hinge shaft 411. The follower 43 is hingedly provided on the second hinge shaft 412. The rear end of the follower 43 is hingedly connected to the locking rod 42, and the front end of the follower 43 is hingedly connected to the clamping member 44. The locking rod 42 includes a screw portion 421, one end of which is provided with a handle portion 422, the other end of which is rotatably connected to the hinge portion 423, and the hinge portion 423 is hingedly connected to the rear end of the follower 43. When in use, the handle 422 of the locking rod 42 is held to twist the entire locking rod 42 , and the locking rod 42 spirals back and drives the follower 43 , which drives the clamping member 44 to clamp the printing substrate on the platen 12 .

[0021] Combined with attachment Figure 4 and attached Figure 5 As shown, the clamping rod rolling mechanism 52 includes a first clamping plate 521, a second clamping plate 522, and an intermediate connecting block 523. The end of the lifting rod 51 is clamped between the first and second clamping plates 521, 522. A rubber pad is sandwiched between the first and second clamping plates 521, 522 to increase the frictional clamping force. The upper end of the intermediate connecting block 523 is fixedly connected to the first clamping plate 521, and the rubber rod 60 is transversely disposed at the lower end of the intermediate connecting block 523. The robotic arm 50 drives the clamping rod rolling mechanism 52 via the lifting rod 51, which in turn drives the rubber rod 60 to roll back and forth on the surface of the printing substrate to test the wear resistance of the printing ink.

[0022] Combined with attachment Figure 1 As shown, the ink abrasion resistance testing device also includes a data acquisition assembly 70 for recording test results. The data acquisition assembly 70 includes a CCD camera 71, a camera mounting bracket 72, and a light source 73. The CCD camera 71 is mounted through the light source 73 and faces the platen 12. The camera mounting bracket 72 is mounted on the fixed base 30. Each time the rubber rod 60 completes a back-and-forth rolling friction on the surface of the printing substrate, the data acquisition assembly 70 takes a picture of the printing ink on the printing substrate, records the ink abrasion resistance test results, and then transmits the picture to a computer for storage and analysis, thereby achieving data acquisition and analysis.
