[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 In an embodiment of the present invention, a wear resistance testing device for printed products includes a base 1, a top surface of which is provided with a driving device 2, a crank-connecting rod mechanism 3, a horizontal sliding mechanism 4, and a linear module mechanism 5;

[0028] The movable end of the linear module mechanism 5 is connected to a friction assembly 6, and the friction assembly 6 has a detachably connected grinding head part 7. The movable end of the horizontal sliding mechanism 4 is connected to a test platform 8, and the test platform 8 has a detachably connected clamping block 9, and the clamping block 9 has a slot 10 for assembling the sample, and the slot 10 is located below the grinding head part 7 and corresponds to the grinding head part 7. The crank-connecting rod mechanism 3 is dynamically connected to the output shaft of the driving device 2, and is used to drive the horizontal sliding mechanism 4 to slide along its horizontal track, so that the clamping block 9 slides horizontally relative to the grinding head part 7.

[0029] In the technical solution of this utility model:

[0030] The drive unit 2 serves as the power source for the entire device. The power it generates is transmitted to the crank-connecting rod mechanism 3 via the output shaft. The crank-connecting rod mechanism 3 is a mechanical device that converts rotational motion into linear reciprocating motion. In this device, the rotational motion of the drive unit 2 is converted into horizontal reciprocating motion by the crank-connecting rod mechanism 3. This conversion enables the device to generate horizontal power in a relatively stable and controllable manner.

[0031] The horizontal sliding mechanism 4 is a key part for achieving relative movement between the sample and the grinding head. The horizontal sliding mechanism 4 is generally composed of a guide rail, a slider 14, and other components. When the crank-connecting rod mechanism 3 generates horizontal reciprocating motion, it drives the slider 14 of the horizontal sliding mechanism 4 to slide along the guide rail. The movable end of the horizontal sliding mechanism 4 is connected to the test platform 8. The clamping block 9 on the test platform 8 is used to fix the printed sample. When the horizontal sliding mechanism 4 moves, the sample on the test platform 8 also moves horizontally.

[0032] The friction assembly 6 is connected to the movable end of the linear module mechanism 5. The linear module mechanism 5 is a device that can accurately control linear motion. It can adjust the position of the friction assembly 6 in the vertical direction. The grinding head 7 on the friction assembly 6 contacts the surface of the sample, simulating the friction conditions in actual use. The grinding head 7 is detachable, which makes it convenient to replace the grinding head 7 of different materials and shapes according to different test requirements. Through the precise control of the linear module mechanism 5, the pressure between the grinding head 7 and the sample can be ensured to be stable, thereby achieving more accurate wear resistance testing.

[0033] The slots 10 on the clamping block 9 are designed to better fix the printed sample. The shape and size of the slots 10 can be adjusted according to different samples, so that the device can adapt to printed products of various sizes and shapes. The clamping block 9 can be detachably connected to the test platform 8 for easy replacement and maintenance.

[0034] In summary, compared with traditional equipment, this design has a clearer and more reasonable structure, a more compact layout of various components, and reduces complex transmission components and tedious operating steps. Operators can more easily perform operations such as sample installation and grinding head replacement, thereby improving test efficiency. The drive device 2 can provide stable power output, while the crank-connecting rod mechanism 3 converts rotational motion into smooth linear reciprocating motion, reducing jamming and power shortages, thereby ensuring the continuity of the test process and improving the accuracy of the test results.

[0035] The clamping block 9 on the test platform 8 is detachably connected and has a slot 10 that can accommodate samples of different sizes and shapes. This greatly improves the versatility of the equipment and can meet the testing needs of various printed materials. Whether it is small labels, bills, or large posters and packaging materials, wear resistance tests can be performed on this equipment; the grinding head part 7 of the friction assembly 6 is detachably connected, which is convenient for replacing the appropriate grinding head part 7 according to different test standards and sample characteristics. Grinding head parts 7 of different materials and shapes can simulate different usage environments and friction conditions, thereby more accurately evaluating the wear resistance of printed materials.

[0036] In an embodiment of the present utility model, the horizontal sliding mechanism 4 includes a first mounting plate 11 and a second mounting plate 12 arranged opposite to each other, a guide column 13 connected between the first mounting plate 11 and the second mounting plate 12, and a slider 14 sliding through the guide column 13, the top surface of the slider 14 is provided with the test platform 8, an opening 15 is provided on one side of the first mounting plate 11 that passes through itself, and the connecting rod of the crank-connecting rod mechanism 3 passes through the opening 15 and is connected to the slider 14.

[0037] The horizontal sliding mechanism 4 is composed of a first mounting plate 11 and a second mounting plate 12 arranged opposite to each other to form a basic frame, which provides stable support for the entire mechanism. The guide column 13 connected between the two mounting plates plays a guiding role to ensure that the movement trajectory of the slider 14 in the horizontal direction is accurate; the slider 14, as a movable component, can slide smoothly along the guide column 13. A test platform 8 is provided on the top surface of the slider 14, so that the test platform 8 can move in the horizontal direction with the movement of the slider 14; an opening 15 is provided on one side of the first mounting plate 11, and the connecting rod of the crank-connecting rod mechanism 3 passes through this opening 15 and is connected to the slider 14. When the driving device 2 drives the crank-connecting rod mechanism 3 to move, the reciprocating motion of the connecting rod is transmitted to the slider 14 through the opening 15, so that the slider 14 slides horizontally along the guide column 13 between the first mounting plate 11 and the second mounting plate 12.

[0038] In the embodiment of the present invention, a plurality of abutment members 16 are provided along the circumference of the clamping block 9 . The abutment members 16 are threadedly engaged with the clamping block 9 , and one end of the abutment member 16 extends into the slot 10 to form an abutment end 17 .

[0039] The clamping block 9 is a key component for fixing the printed sample. A plurality of abutment members 16 are provided on its circumferential side. These abutment members 16 are connected to the clamping block 9 by threaded engagement, so that the abutment members 16 can be rotated and adjusted on the clamping block 9. When the abutment member 16 rotates, due to the action of the thread, the abutment member 16 moves along the radial direction of the clamping block 9, and one end of the abutment member 16 extends into the slot 10 of the clamping block 9 to form an abutment end 17, which can contact the printed sample placed in the slot 10. By rotating the abutment member 16, the abutment end 17 gradually approaches and finally tightly abuts against the surface of the printed sample. Since a plurality of abutment members 16 are distributed on the circumferential side of the clamping block 9, pressure can be applied to the sample from different directions, thereby achieving a firm clamping of the sample.

[0040] Multiple abutment members 16 apply pressure to the sample from different directions, which can ensure that the printed sample will not loosen or shift during the test. This firm clamping method improves the accuracy and reliability of the test results. Furthermore, the abutment end 17 of the abutment member 16 can be adjusted according to the material and shape of the sample to avoid excessive squeezing or damage to the sample. At the same time, the evenly distributed abutment force can reduce local deformation of the sample during the clamping process and protect the integrity of the sample.

[0041] In the embodiment of the present invention, the linear module mechanism 5 includes a base 18, a guide rod 19 and a threaded column 20 located in the base 18, and a connecting slider 21 connected to the guide rod 19 and the threaded column 20, and the friction assembly 6 is connected to the connecting slider 21;

[0042] A knob 22 cooperating with the threaded column 20 is provided at the top of the base 18 so as to adjust the height of the connecting slider 21 and the friction assembly 6 relative to the base surface through the knob 22 .

[0043] The linear module mechanism 5 consists of a machine base 18, a guide rod 19, a threaded column 20 and a connecting slider 21. The machine base 18 provides support and installation foundation for the entire mechanism. The guide rod 19 and the threaded column 20 are arranged in parallel in the machine base 18, and the connecting slider 21 is connected to the guide rod 19 and the threaded column 20 at the same time; the friction component 6 is connected to the connecting slider 21. When the connecting slider 21 moves in the machine base 18, it drives the friction component 6 to adjust its position in the vertical direction; a knob 22 is provided at the top of the machine base 18 to cooperate with the threaded column 20. When the knob 22 is rotated, the threaded column 20 rotates accordingly. Due to the action of the thread, the connecting slider 21 that cooperates with the threaded column 20 will move in the vertical direction along the guide rod 19, that is, by rotating the knob 22, the height of the connecting slider 21 and the friction component 6 relative to the base surface can be accurately controlled, thereby adjusting the distance and pressure between the grinding head 7 and the printed sample.

[0044] In the embodiment of the present invention, the friction assembly 6 includes a support block 23 slidably connected to the connecting slider 21 through a guide column 13. A plurality of threaded holes 24 are formed on the support block 23, and the grinding head 7 is threadedly connected to any threaded hole 24.

[0045] The support block 23 in the friction assembly 6 is slidably connected to the connecting slider 21 via the guide post 13. This connection allows the support block 23 to move vertically under the drive of the connecting slider 21 while maintaining a certain degree of stability in the horizontal direction. The support block 23 is provided with a plurality of threaded holes 24, and the grinding head 7 is threadedly connected to any of the threaded holes 24. Through the threaded connection, the grinding head 7 can be firmly mounted on the support block 23 and can be replaced as needed.

[0046] Furthermore, when there are multiple staggered threaded holes 24 on the support block 23 and multiple grinding head parts 7 are installed, under the control of the linear module mechanism 5, the support block 23 descends as a whole, and these grinding head parts 7 can contact different parts of the printed sample at the same time. Since the crank-connecting rod mechanism 3 drives the horizontal sliding mechanism 4, the sample moves in the horizontal direction, and multiple grinding head parts 7 can perform wear resistance tests on multiple different parts of the sample at the same time. This is similar to carrying out multiple small tests on a test platform 8 at the same time, which is very helpful for evaluating the differences in wear resistance performance of different positions of printed products.

[0047] In the embodiment of the present invention, a ball 25 is provided at the bottom end of the grinding head 7 .

[0048] Normally, the grinding head 7 is in direct contact with the printed sample for friction testing. After the ball 25 is arranged at the bottom end of the grinding head 7, the friction mode between the grinding head 7 and the sample changes. When the grinding head 7 contacts the sample under the action of vertical pressure, the ball 25 will roll on the surface of the sample, thereby converting the original sliding friction into rolling friction; the presence of the ball 25 enables the grinding head 7 to move more smoothly on the sample surface when the horizontal sliding mechanism 4 drives the sample to move horizontally. The ball 25 can reduce the friction between the grinding head 7 and the sample, and improve the stability and accuracy of the movement of the grinding head 7; at the same time, the ball 25 can also evenly transfer the horizontal force to the grinding head 7, so that the grinding head 7 can better simulate the friction conditions in actual use during the test.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
