Description

Technical Field

[0001] The utility model relates to the field of ink wear-resistant testing devices, in particular to a screen printing ink wear-resistant testing device for ink processing. Background Technique

[0002] A screen is a general term for various mesh products, such as guardrail nets, window screens, etc. Many of the mesh products need to be printed with ink for purposes such as corrosion resistance, oxidation resistance, or aesthetics. The wear resistance of the ink directly determines important factors such as the maintenance period and service life of the screen. Therefore, it is necessary to conduct wear-resistant tests on the ink used for screen printing during the processing.

[0003] In the prior art, a patent document with an application number of CN202222563565.3, which was examined and published by the State Intellectual Property Office of China, discloses a screen printing ink wear-resistant testing device for ink processing, including a chassis, a test bench, a friction seat, and a sample friction plate. A test bench is fixedly installed at the bottom of one side of the chassis, a sample friction plate is installed on the top of the test bench, and a friction seat is movably arranged on the top of the sample friction plate; by setting a clamping mechanism, when pressing the sample, only need to press down the hanging plate and then rotate it to hang it under the test bench. When releasing, rotate the hanging plate at a certain angle to disengage from the bottom of the test bench, and the spring will automatically push the support frame to drive the pressing plate to loosen the clamped sample, making the clamping and releasing of the test sample quick, simple, and convenient, improving the test efficiency. Moreover, the clamping mechanism is suspended on both sides of the top of the sample friction plate, so when placing the sample, it can be directly placed between the pressing plate and the sample friction plate. When placing, the clamping mechanism does not block the sample at all, making it more convenient to take and place the sample.

[0004] However, the distance between the test bench and the friction seat of the screen printing ink wear-resistant testing device for ink processing in the prior art is fixed. On the one hand, this makes it inevitable that there will be friction between the sample and the friction seat when taking and placing the sample on the test bench, and this friction occurs in an uncontrollable state, so it will inevitably lead to deviation in the test results. On the other hand, it also makes the screen printing ink wear-resistant testing device for ink processing unable to test samples with different thicknesses. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some embodiments of the present utility model, but not all embodiments. They are only used to explain the embodiments of the present utility model and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 , the present utility model provides a technical solution: a screen printing ink wear resistance testing device for ink processing, including: a chassis 1, an activity groove 4 is opened on the surface of the chassis 1, a connecting rod 5 is slidably connected in the activity groove 4, a friction seat 6 is arranged at the bottom end of the connecting rod 5, a test bench installation groove 2 is opened on the surface of the chassis 1, a hydraulic tappet insertion hole 8 is opened at the bottom end of the chassis 1, a hydraulic tappet mechanism 9 is fixed at the bottom end of the chassis 1, the tappet of the hydraulic tappet mechanism 9 is movably inserted in the hydraulic tappet insertion hole 8, and the top end of the tappet of the hydraulic tappet mechanism 9 is fixed with a test bench 3, the test bench 3 is movably inserted in the test bench installation groove 2, a sample 7 is arranged between the test bench 3 and the friction seat 6, and a clamping assembly is arranged on the surface of the chassis 1.

[0021] For this screen printing ink wear resistance testing device for ink processing, a test bench installation groove 2 is opened on the surface of the chassis 1, a hydraulic tappet mechanism 9 is fixed at the bottom end of the chassis 1, the tappet of the hydraulic tappet mechanism 9 passes through the hydraulic tappet insertion hole 8 and extends into the test bench installation groove 2 and is fixed with a test bench 3. By adjusting the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder, the height of the test bench 3 can be adjusted, so as to achieve the purpose of adjusting the distance between the test bench 3 and the friction seat 6. Before the test starts, when the sample 7 needs to be placed on the top of the test bench 3, the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder is shortened, so that the test bench 3 moves downward in the test bench installation groove 2, making the distance between the test bench 3 and the friction seat 6 greater than the thickness of the sample 7. Then, the sample 7 can be placed on the top of the test bench 3 on the premise of avoiding the contact between the top end of the sample 7 and the bottom end of the friction seat 6, so as to avoid the friction seat 6 causing wear to the sample 7 before the test and affecting the test results. Similarly, before removing the sample 7 from the top of the test bench 3 after the test is completed, the height of the test bench 3 is also lowered first, so that the sample 7 is away from the friction seat 6 and then the sample 7 is removed from the top of the test bench 3, so as to avoid the friction seat 6 causing new wear to the sample 7 after the test is completed and affecting the test results. At the same time, because the height of the test bench 3 is adjustable, the device can also test samples 7 of various different thicknesses; after the sample 7 is placed on the test bench 3, the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder is increased, so that the test bench 3 moves upward until the top end of the sample 7 abuts against the bottom end of the friction seat 6. Then, the connecting rod 5 can be slid in the activity groove 4, driving the friction seat 6 to slide on the top of the sample 7, so that the friction seat 6 generates friction on the sample 7, and the wear resistance of the sample 7 is tested.

[0022] Embodiment 2: On the basis of Embodiment 1, in order to enable the test bench 3 to only move up and down, a guide hole 10 is opened at the bottom end of the chassis 1. A guide rod 11 is movably inserted into the guide hole 10. The top end of the guide rod 11 is fixed to the bottom end of the test bench 3. The bottom end of the guide rod 11 extends out of the bottom end of the guide hole 10. Four groups of guide rods 11 are provided, and the four groups of guide rods 11 are symmetrically arranged in pairs with respect to the test bench 3.

[0023] By fixing the guide rod 11 at the bottom end of the test bench 3 and opening the guide hole 10 at the bottom end of the chassis 1, the guide rod 11 is movably inserted into the guide hole 10 so that the guide hole 10 guides the movement of the guide rod 11, and further the guide rod 11 guides the movement of the test bench 3, realizing that the test bench 3 can only move up and down.

[0024] Embodiment 3: On the basis of Embodiment 2, in order to clamp the sample 7, a clamping assembly is provided on the surface of the chassis 1. The clamping assembly includes: a clamping plate 16. The clamping plate 16 is in the structure of a rectangular plate body. Two groups of clamping plates 16 are provided. The two groups of clamping plates 16 are symmetrically distributed with respect to the test bench mounting groove 2. The bottom ends of the two groups of clamping plates 16 respectively abut against both sides of the top end of the sample 7. Two groups of support rods 14 are fixed to the bottom end of each group of clamping plates 16. The support rods 14 are in the structure of a circular rod body. The support rods 14 are movably inserted into the clamping assembly mounting groove 12. The clamping assembly mounting groove 12 is opened on the surface of the chassis 1. A spring plate 13 is fixed to the bottom end of the support rod 14. The spring plate 13 is in the structure of a circular plate body. A spring 15 is sleeved on the rod body of the support rod 14. The top end of the spring 15 abuts against the inner wall of the groove body of the clamping assembly mounting groove 12. The bottom end of the spring 15 abuts against the top end of the spring plate 13. A handle 17 is fixed to the top end of the clamping plate 16. A sleeve 18 is fixed to the surface of the chassis 1. One end of the sleeve 18 away from the chassis 1 is movably inserted with a telescopic rod 19. The telescopic rod 19 is movably inserted between the handle 17 and the clamping plate 16.

[0025] Before placing the sample 7 on the test bench 3, pull the handle 17 upward. After lifting the handle 17 to the same height as the telescopic rod 19, pull out a part of the telescopic rod 19 from the sleeve 18, and then insert the telescopic rod 19 between the clamping plate 16 and the handle 17 to limit the clamping plate 16 at a high position, preventing the clamping plate 16 from obstructing the placement of the sample 7. At this time, the support rod 14 extends out of the clamping component installation groove 12, driving the spring plate 13 to move upward in the clamping component installation groove 12, and further compressing the spring 15. After placing the sample 7 on the top of the test bench 3 and adjusting the height of the test bench 3 so that the top of the sample 7 abuts against the bottom of the friction seat 6, push the telescopic rod 19 into the sleeve 18, so that the telescopic rod 19 withdraws from between the clamping plate 16 and the handle 17, and then slowly release the clamping plate 16 downward until the bottom end of the clamping plate 16 abuts against the top of the sample 7. At this time, the support rod 14 is still in a state of extending out of the clamping component installation groove 12, and the spring 15 is still compressed. Then, the spring 15 generates a downward thrust on the spring plate 13 under its own elastic action, and the spring plate 13 generates a downward pulling force on the support rod 14. This pulling force is transmitted to the clamping plate 16, making the clamping plate 16 firmly press on the top of the sample 7, thereby clamping the sample 7 between the clamping plate 16 and the test bench 3; when removing the sample 7 from the test bench 3, limit the clamping plate 16 at a high position again through the telescopic rod 19, and then lower the height of the test bench 3 and remove the sample 7 from the test bench 3, so as to prevent the clamping plate 16 from obstructing the removal of the sample 7.

[0026] Embodiment 3: On the basis of Embodiment 2, in order to provide sufficient movement space for the guide rod 11, a base 20 is fixed to the bottom end of the chassis 1.

[0027] Fixing the base 20 at the bottom end of the chassis 1 raises the height of the chassis 1, thereby providing sufficient movement space for the guide rod 11.

[0028] During actual use, a test bench installation groove 2 is opened on the surface of the chassis 1, a hydraulic tappet mechanism 9 is fixed at the bottom end of the chassis 1, the tappet of the hydraulic tappet mechanism 9 passes through the hydraulic tappet insertion hole 8 and extends into the test bench installation groove 2 and is fixed with a test bench 3. By adjusting the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder, the height of the test bench 3 is adjusted, so as to achieve the purpose of adjusting the distance between the test bench 3 and the friction seat 6. Before the test starts, when the sample 7 needs to be placed on the top of the test bench 3, the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder is shortened, so that the test bench 3 moves downward in the test bench installation groove 2, making the distance between the test bench 3 and the friction seat 6 greater than the thickness of the sample 7. Then, the sample 7 can be placed on the top of the test bench 3 on the premise of avoiding the top of the sample 7 contacting the bottom end of the friction seat 6, so as to avoid the friction seat 6 causing wear to the sample 7 before the test and affecting the test results. Similarly, before removing the sample 7 from the top of the test bench 3 after the test is completed, the height of the test bench 3 is also lowered first, so that the sample 7 is far away from the friction seat 6 and then the sample 7 is removed from the top of the test bench 3, so as to avoid the friction seat 6 causing new wear to the sample 7 after the test is completed and affecting the test structure. At the same time, because the height of the test bench 3 is adjustable, the device can also test samples 7 of various different thicknesses; after the sample 7 is placed on the test bench 3, the length of the tappet of the hydraulic tappet mechanism 9 extending out of the hydraulic cylinder is increased, so that the test bench 3 moves upward until the top of the sample 7 abuts against the bottom end of the friction seat 6. Then, the connecting rod 5 can slide in the moving groove 4, driving the friction seat 6 to slide on the top of the sample 7, so that the friction seat 6 generates friction on the sample 7 to test the wear resistance of the sample 7; by fixing a guide rod 11 at the bottom end of the test bench 3 and opening a guide hole 10 at the bottom end of the chassis 1, the guide rod 11 is movably inserted into the guide hole 10, so that the guide hole 10 guides the movement of the guide rod 11, and further the guide rod 11 guides the movement of the test bench 3, realizing that the test bench 3 can only move up and down;Before placing the sample 7 on the test bench 3, pull the handle 17 upward until the handle 17 is lifted to the same height as the telescopic rod 19. Then, pull out a part of the telescopic rod 19 from the sleeve 18, and insert the telescopic rod 19 between the clamping plate 16 and the handle 17 to limit the clamping plate 16 at a high position, preventing the clamping plate 16 from obstructing the placement of the sample 7. At this time, the support rod 14 extends out of the clamping component installation groove 12, driving the spring plate 13 to move upward in the clamping component installation groove 12, and further compressing the spring 15. After placing the sample 7 on the top of the test bench 3 and adjusting the height of the test bench 3 so that the top of the sample 7 abuts against the bottom of the friction seat 6, push the telescopic rod 19 into the sleeve 18, causing the telescopic rod 19 to withdraw from between the clamping plate 16 and the handle 17. Then, slowly release the clamping plate 16 downward until the bottom end of the clamping plate 16 abuts against the top of the sample 7. At this time, the support rod 14 is still in the state of extending out of the clamping component installation groove 12, and the spring 15 is still compressed. Then, the spring 15 generates a downward thrust on the spring plate 13 under its own elastic action, and the spring plate 13 generates a downward pulling force on the support rod 14. This pulling force is transmitted to the clamping plate 16, causing the clamping plate 16 to firmly press on the top of the sample 7, thereby clamping the sample 7 between the clamping plate 16 and the test bench 3. When removing the sample 7 from the test bench 3, limit the clamping plate 16 at a high position again through the telescopic rod 19, and then lower the height of the test bench 3 and remove the sample 7 from the test bench 3, thereby preventing the clamping plate 16 from obstructing the removal of the sample 7. Fix a base 20 at the bottom end of the chassis 1, and the base 20 raises the height of the chassis 1, thereby providing sufficient movement space for the guide rod 11.;
