Description

Technical Field

[0001] This utility model relates to abrasion-resistant labels, and in particular to an abrasion resistance testing device for abrasion-resistant labels. Background Technology

[0002] Abrasion-resistant labels are specially designed labels with strong resistance to abrasion, tearing, and chemical corrosion. These labels are typically used in environments where long-term legibility is required, especially in industrial, logistics, and outdoor applications.

[0003] To ensure product quality, manufacturers need to sample abrasion-resistant labels from the same batch for abrasion resistance testing before they leave the factory. Existing testing equipment, such as the abrasion resistance testing device for special label printing (announcement number CN218271810U), uses a servo motor, reciprocating screw, nut, moving seat, gear plate, rotating gear, rotating rod, cylinder, and grinding disc to drive the grinding disc to rotate and reciprocate left and right, thus grinding the printed content of the special label. Each grinding pass is counted by a counter. When the grinding disc wears away the printed content of the special label, the counter counts how many grinding passes have been completed, and the number of grinding passes is used to judge the abrasion resistance of the special label printing, making the abrasion resistance test more intuitive and accurate. However, after the test, technicians need to manually remove the tested samples, which is cumbersome and not conducive to improving testing efficiency.

[0004] To address the above issues, we propose an abrasion resistance testing device for abrasion-resistant labels. Utility Model Content

[0005] This invention proposes an abrasion resistance testing device for abrasion-resistant labels, which solves the aforementioned problems existing in the use of existing technologies.

[0006] The technical solution of this utility model is implemented as follows: an abrasion resistance testing device for abrasion-resistant labels, including a platform, a mounting frame fixedly mounted on the platform, a testing table fixedly mounted on the platform, and fixing components symmetrically arranged on the left and right sides of the testing table on the platform.

[0007] The test bench has a movable cavity, and rotating plates are symmetrically connected to the left and right sides of the movable cavity. The platform has an upward-facing recovery cavity, and a negative pressure fan connected to the recovery cavity is installed at the bottom of the platform. The platform is equipped with a movable door connected to the recovery cavity.

[0008] A left-right movable testing mechanism is provided above the testing platform, and a driving mechanism for driving the testing mechanism is installed on the mounting frame.

[0009] A further feature of this invention is that a through hole is provided on the bottom wall of the recovery chamber, the air inlet pipe of the negative pressure fan is located in the through hole, and a filter screen is provided in the through hole.

[0010] A further feature of this invention is that the rotating plate is rotatably connected to the movable cavity via a rotating shaft, and rotating cylinders for driving the rotating plate are symmetrically installed on the left and right sides of the rear side of the test platform, and the piston rod of the negative pressure fan is fixedly connected to the end of the rotating shaft.

[0011] A further feature of this invention is that the driving mechanism includes a reciprocating lead screw;

[0012] The mounting bracket is symmetrically fixed with mounting plates on the left and right sides. The reciprocating lead screw is rotatably connected between the two mounting plates. A servo motor for driving the reciprocating lead screw is mounted on one of the mounting plates.

[0013] A further feature of this invention is that the testing mechanism includes a movable seat, which is threadedly connected to the reciprocating lead screw.

[0014] A cylinder is installed inside the movable seat. A test seat is fixedly connected to the end of the piston rod of the cylinder, and a test piece is fixedly connected to the test seat.

[0015] A further feature of this invention is that the test piece includes a mounting block and a slitting plate, the slitting plate being fixedly connected to the lower end of the mounting block;

[0016] The test socket has a downward-facing mounting groove, and a bolt that penetrates the front and rear side walls is provided in the mounting groove. The mounting block has a through-hole that penetrates the front and rear, and the bolt is inserted into the through-hole.

[0017] The bolt has a nut threaded onto its end.

[0018] A further feature of this invention is that the fixing component includes two cylinders, which are symmetrically mounted on the platform.

[0019] Each piston rod of the second cylinder is fixedly connected to a pressure plate, which presses against the rotating plate.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] After the test is completed, the rotating plate swings downward to allow the sample to fall into the recovery chamber, which simplifies the process of manually removing the sample by the tester and effectively improves the testing efficiency.

[0022] Testers can replace the test piece by loosening the nut on one side and removing the bolt, thus simulating different instruments scratching the surface of the sample to be tested, thereby enriching the experimental data and making the test results more accurate. Attached Figure Description

Detailed Implementation

[0032] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example:

[0034] like Figures 1 to 7 As shown, an abrasion resistance testing device for abrasion-resistant labels includes a platform 11, a mounting frame 12 fixed on the platform 11, a testing stage 13 fixed on the platform 11, a movable cavity 14 opened in the testing stage 13, and rotating plates 15 for placing the sample to be tested symmetrically connected to the left and right sides of the movable cavity 14. Two second cylinders 36 are symmetrically installed on the platform 11. The piston rod end of the second cylinder 36 is fixedly connected to a pressure plate 37. After the technician places the sample to be tested on the rotating plate 15, the second cylinder 36 drives the pressure plate 37 to move downward until it presses against the surface of the sample to be tested, so as to fix the sample to be tested.

[0035] Mounting plates 24 are symmetrically fixed on the mounting bracket 12. A reciprocating screw 23 is rotatably connected between the two mounting plates 24. A servo motor 25 for driving the reciprocating screw 23 is installed on one of the mounting plates 24. A movable seat 26 is threaded onto the reciprocating screw 23. The movable seat 26 is moved back and forth by the reciprocating screw 23. A cylinder 27 is installed inside the movable seat 26. A test seat 28 is fixedly connected to the end of the piston rod of the cylinder 27. A test piece 29 for testing wear-resistant labels is fixedly connected to the test seat 28.

[0036] The specific connection method between the test piece 29 and the movable seat 26 is as follows: the test piece 29 includes a mounting block 30 and a slitting plate 31. The slitting plate 31 is fixedly connected to the lower end of the mounting block 30. The test seat 28 has a downward-facing mounting groove 32. The mounting block 30 is inserted into the mounting groove 32. The mounting block 30 has a through-hole 34. A bolt 33 is provided in the through-hole 34. The front and rear ends of the bolt 33 penetrate the front and rear side walls of the mounting groove 32. The end of the bolt 33 is threaded with a nut 38. Through the above structure, the test piece 29 can be fixed in the movable seat 26. When the tester wants to control variables and simulate different instruments sliding on the surface of the sample to be tested, he only needs to loosen the nut 38 to remove the bolt 33 and replace it with a different type of test piece 29.

[0037] After the tester fixes the sample to be tested, the first cylinder 27 drives the test piece 29 to move downward until the slitting plate 31 contacts the surface of the sample to be tested. Then, the test piece 29 starts to move back and forth for a period of time. The tester observes the wear condition of the surface of the sample to be tested and can then evaluate the wear resistance of the sample.

[0038] The platform 11 has a recovery chamber 17 for recovering samples. A negative pressure fan 16 connected to the recovery chamber 17 is installed at the bottom of the platform 11. A through hole 19 is provided on the bottom wall of the recovery chamber 17. The air inlet pipe of the negative pressure fan 16 is located in the through hole 19, and a filter screen 20 is provided in the through hole 19 to prevent the sample from clogging the air inlet pipe of the negative pressure fan 16. The platform 11 is provided with a movable door 18 that communicates with the recovery chamber 17. The tester can open the movable door 18 to collect and take out the sample in the recovery chamber 17.

[0039] Furthermore, the specific connection between the rotating plate 15 and the test platform 13 is as follows: the rotating plate 15 is rotatably connected to the movable cavity 14 via a rotating shaft 21. Rotating cylinders 22 for driving the rotating plate 15 are symmetrically installed on the rear side of the test platform 13. The piston rod of the rotating cylinder 22 is fixedly connected to the end of the rotating shaft 21. With this structure, after the test is completed, the rotating shaft 21 rotates under the drive of the rotating cylinders, causing the rotating plate 15 to swing downwards, thus allowing the sample to fall into the recovery cavity 17. When the rotating plate 15 opens downwards, the negative pressure fan 16 operates, placing the recovery cavity 17 under negative pressure, thereby quickly recovering the tested sample and eliminating the need for manual sample removal by the testing personnel, effectively improving testing efficiency.
