Description

Technical Field

[0001] This utility model relates to the field of ink testing technology, and in particular to an ink adhesion testing device. Background Technology

[0002] Ink adhesion testing is one of the important methods for evaluating ink quality. By testing the adhesion of ink to the surface of the paper being tested, it is possible to prevent ink with insufficient adhesion from being printed onto the packaging surface, thereby avoiding ink contamination or peeling of the printed packaging during use due to friction.

[0003] The ink adhesion test involves placing the paper to be tested on a flat surface with the ink side away from the surface. A predetermined weight of friction block is held and rubbed back and forth on the surface of the paper a predetermined number of times. After the friction block is removed, the ink adhesion is judged based on the rubbing marks.

[0004] However, since different people use different forces and speeds when rubbing the surface of the paper with the friction block, and even the same person's force and speed when holding the friction block vary, the friction marks on the surface of the paper after being rubbed by the friction block will vary, making it impossible to judge whether the ink adhesion is qualified based on the friction marks.

[0025] refer to Figures 1 to 4The ink adhesion testing device according to a preferred embodiment of the present invention will be described in detail below, wherein the ink adhesion testing device includes a device body 10, a mounting component 20, a reciprocating component 30 and at least a friction component 40.

[0026] In this embodiment, the mounting assembly 20 includes at least two positioning members 21. The positioning members 21 are used to abut a test piece 91 against the surface of the device body 10 with one ink surface 9101 of the test piece 91 facing outwards. The positioning member 21 includes a connecting bracket 211, a threaded member 212, and a positioning block 213. The connecting bracket 211 is mounted on the device body 10. The connecting bracket 211 has a connecting through hole, the inner wall of which has a threaded groove that matches the surface of the threaded member 212, so that the threaded member 212 is movably disposed in the connecting through hole. The positioning block 213 is lockably connected to the threaded member 212 and is located near the end of the device body 10. The two ends of the ink surface 9101 of the test piece 91 are respectively located between the two positioning blocks 213 and the main body 10 of the device. The positioning blocks 213 can be pressed against the ends of the ink surface 9101 of the test piece 91 under the drive of the threaded part 212.

[0027] It should be noted that the surface of the device body 10 may be uneven, which may prevent the test piece 91 from fitting properly to the device body 10.

[0028] In another modified embodiment, the mounting assembly 20 includes at least two positioning members 21 and a flattening member 22. The flattening member 22 is disposed on the device body 10. The test piece 91 is abutted against the surface of the flattening member 22 by means of the positioning members 21 with the ink surface 9101 facing outward. The positioning member 21 includes a connecting bracket 211, a threaded member 212, and a positioning block 213. The connecting bracket 211 is mounted on the device body 10. The connecting bracket 211 has a connecting through hole, the inner wall of which has a threaded groove that matches the surface of the threaded member 212, so that the threaded member 212 is movably disposed in the connecting through hole. The positioning block 213 is lockably connected to the threaded member 212 and is located near the end of the device body 10. The two ends of the ink surface 9101 of the test piece 91 are respectively located between the two positioning blocks 213 and the flattening part 22, so that they are abutted against the surface of the flattening part 22 by the positioning blocks 213. The positioning blocks 213 can be pressed against the ends of the ink surface 9101 of the test piece 91 under the drive of the threaded part 212.

[0029] To enable those skilled in the art to understand this utility model, in at least one embodiment of this utility model, the example is simply that the mounting component 20 includes at least two positioning members 21 and the flattening member 22.

[0030] It should be noted that during the rotation of the threaded component 212 in the connecting through hole, the positioning block 213 will be pushed towards the test piece 91 by the threaded component 212. However, when the positioning block 213 is pushed towards the ink surface 9101 with its surface facing the ink surface 9101 at an angle to the ink surface 9101, the positioning block 213 cannot bring the test piece 91 into contact with and abut against the device body 10.

[0031] Preferably, the threaded component 212 has a rotating portion 2121 at the end near the device body 10, and the rotating portion 2121 is located at the end of the threaded component 212 near the positioning block 213. The positioning block 213 has a rotating connection portion 2131, and the rotating portion 2121 is movably connected to the rotating connection portion 2131 via a rotating shaft.

[0032] Preferably, the positioning member 21 further includes at least one guide member 214. The positioning block 213 has an anti-deviation through hole 21301 that matches the guide member 214. The guide member 214 is disposed on the connecting frame 211 and is movably passed through the anti-deviation through hole 21301. The guide member 214 is used to prevent the positioning block 213 from deviating during its movement toward the ink surface 9101.

[0033] It is worth mentioning that when the threaded part 212 pushes the positioning block 213 toward the ink surface 9101, the rotation of the positioning block 213 causes the surface of the positioning block 213 facing the ink surface 9101 to adhere to the ink surface 9101, and the test piece 91 is attached to and abuts against the main body 10 of the device.

[0034] In this embodiment, the reciprocating assembly 30 includes a driving member 31, a rotating member 32, at least one limiting member 33, and a connecting member 34. The driving member 31 and the limiting member 33 are both mounted on the device body 10. The rotating member 32 is rotatably coaxially connected to the output end of the driving member 31. The extending direction of the rotating member 32 is parallel to the ink surface 9101 of the test piece 91. The surface of the rotating member 32 has threads along its extending direction, and the connecting member 34 has a through hole that matches the threads on the surface of the rotating member 32, allowing the rotating member 32 to movably pass through the connecting member 34. The limiting member 33 extends in the same direction as the rotating member 32. The connecting member 34 forms a sliding through hole that matches the limiting member 33, and the connecting member 34 is movably disposed on the limiting member 33 through the sliding through hole. The mounting body 41 is disposed on the connecting member 34.

[0035] Specifically, the friction assembly 40 includes a mounting body 41 and at least one friction block 42. The friction block 42 is connected to the mounting body 41 such that it faces and abuts against the ink surface 9101. The mounting body 41 is disposed on the connector 34 and reciprocates under the action of the connector 34, thereby causing the friction block 42 to reciprocate on the ink surface 9101.

[0036] It is worth mentioning that when the output end of the drive member 31 rotates in different directions, since the protrusion of the connector 34 is slidably disposed in the groove of the limiting member 33, the connector 34 drives the friction block 42 to reciprocate on the ink surface 9101 through the mounting body 41 to rub the ink surface 9101.

[0037] Preferably, the end of the friction block 42 facing the ink surface 9101 has a plurality of friction elements 421, the plurality of friction elements 421 are interleaved, and the friction elements 421 are used to uniformly distribute the friction force on the ink surface 9101.

[0038] Those skilled in the art will understand that, during the process of the drive member 31 driving the rotating member 32 to rotate and the connecting member 34 moving in a predetermined direction under the limiting and guiding of the limiting member 33, the mounting body 41 will be driven by the connecting member 34 and will drive the friction member 421 of the friction block 42 to rub against the ink surface 9101.

[0039] Furthermore, after the friction block 42 rubs the ink surface 9101 a predetermined number of times, the test piece 91 is removed, and the ink surface 9101 of the test piece 91 after rubbing can be tested to determine whether the ink on the ink surface 9101 meets the ink adhesion test.

[0040] It should be noted that during the ink adhesion test, the surface condition of the ink surface 9101 after friction varies depending on the pressure applied by the friction block 42 against the ink surface 9101. Therefore, different pressures are required when pressing the friction element 421 of the friction block 42 against the ink surface 9101. In other words, the ink adhesion test results are different after pressing the friction element 421 of the friction block 42 against the ink surface 9101 and rubbing the ink surface 9101 with different pressures, making the ink adhesion test results more valuable for reference.

[0041] In this embodiment, the mounting body 41 has an insertion groove 4101. The connector 34 has an insertion end 341. The insertion end 341 is located at a predetermined position above the ink surface 9101. The insertion groove 4101 matches the insertion end 341 so that the insertion end 341 of the connector 34 is movably disposed in the insertion groove 4101, thereby facilitating the replacement of mounting bodies 41 of different weights and achieving the purpose of pressing the friction element 421 of the friction block 42 against the ink surface 9101 with different pressures.

[0042] In another modified embodiment, the friction assembly 40 further includes at least one weighting block 43. The weighting block 43 is disposed on the mounting body 41 to change the pressure of the friction element 421 of the friction block 42 pressing against the ink surface 9101.

[0043] It should be noted that when removing the test piece 91 from the surface of the flattening piece 22, the mounting body 41 needs to be moved first to move the friction block 42 connected to the mounting body 41 away from the ink surface 9101 of the test piece 91, thereby moving the friction block 421 away from the ink surface 9101. However, if the mounting body 41 shakes during the movement of the mounting body 41, the friction block 421 will rub against the ink surface 9101, causing damage to the surface of the ink surface 9101 after being rubbed, ultimately affecting the ink adhesion test result of the ink surface 9101.

[0044] Preferably, the mounting body 41 has at least one movable handle 411, which facilitates the movement of the mounting body 41 to avoid shaking during the movement of the mounting body 41.

[0045] It is worth mentioning that the ink adhesion testing device also includes a control component 50. The control component 50 is disposed on the main body 10 of the device. The drive component 31 is electrically connected to the control component 50 so as to control the rotation speed and rotation direction of the drive component 31 through the control component 50, thereby controlling the speed at which the friction component 421 rubs on the ink surface 9101.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
