Description

Technical Field

[0001] This utility model relates to the field of cardboard surface abrasion resistance testing technology, and in particular to an object surface abrasion resistance tester. Background Technology

[0002] Cardboard boxes are packaging containers made of cardboard, commonly used for loading, transporting, and storing various goods. They are lightweight, economical, easy to manufacture, and recyclable, and are widely used in logistics, retail, and industrial fields. During transportation, cardboard boxes may be subjected to friction, collision, or wear. Cardboard boxes with strong abrasion resistance can better protect the goods inside and reduce damage. Therefore, abrasion resistance tests need to be conducted on the cardboard used to make cardboard boxes during the production process. Selecting cardboard boxes with better abrasion resistance can reduce losses and costs.

[0003] The traditional method for testing the abrasion resistance of cardboard boxes involves workers holding a hard object (such as a plastic scraper) and scraping the surface of the box under certain pressure to observe scratches, peeling, or damage. Each test requires manual operation, which is time-consuming and labor-intensive. Especially when there are a large number of samples, continuous pressure and scraping by hand may cause fatigue and affect the test results. Therefore, it is necessary to design a surface abrasion resistance tester to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface wear resistance tester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surface abrasion resistance tester includes a tray, a movable seat at the top of the tray, fixed shafts fixedly connected to both sides of the movable seat, rollers sleeved on the fixed shafts, the rollers rotatably connected to the fixed shafts, a guide plate on one side of the rollers, and first guide rods fixedly connected to the top of both ends of the guide plate. A mounting frame is fixedly connected to the top of the tray, the first guide rods passing through the mounting frame and slidably connected to the mounting frame. Four springs are provided at the top of the mounting frame, each spring sleeved on one of the four first guide rods. Guide holes are provided at the positions of the first guide rods on the mounting frame, and the first guide rods are disposed within the guide holes. A pressure plate is provided at the bottom of the guide plate, and an adjustment mechanism for adjusting the height of the pressure plate is provided on the guide plate. Two fixed rods are fixedly connected to one side of the movable seat, and the two fixed rods are fixedly connected to the same L-shaped plate. Two second guide rods pass through the L-shaped plate and slidably connect to the L-shaped plate. The bottom of the two second guide rods is fixedly connected to the same horizontal plate. A friction pad is fixedly connected to the bottom of the plate, and sliders are fixedly connected to both sides of the horizontal plate. The two pressure plates each have a groove on their adjacent sides, and the sliders are positioned within the grooves. The sliders slidably connect to the pressure plates. Because the friction pad and pressure plates are lowered during movement, the pressure plates press and fix the cardboard box as it descends. Simultaneously, the friction pad contacts the cardboard box and applies pressure. Continuing to move the friction pad laterally allows for abrasion resistance testing of the cardboard box. Moving the roller to the other end of the guide plate raises the pressure plates and friction pad, allowing the tested cardboard box to be removed. This effectively solves the problem mentioned in the background art that traditional abrasion resistance testing of cardboard boxes requires manual operation for each test, which is time-consuming and labor-intensive. Especially with a large number of samples, continuous manual pressure and scraping can cause fatigue and affect test results. This method achieves simple operation, facilitates abrasion resistance testing of cardboard boxes, and effectively avoids prolonged manual pressure application by workers, reducing labor intensity and fatigue risks.

[0007] Preferably, the adjusting mechanism includes a threaded sleeve, which passes through a guide plate and is fixedly connected to the guide plate. A threaded rod passes through the threaded sleeve and is adapted to the threaded sleeve. A knob is fixedly connected to the top of the threaded sleeve, and a rotating shaft is fixedly connected to the bottom of the threaded rod. A sleeve is fitted onto the rotating shaft, and the rotating shaft is rotatably connected to the sleeve. The top of a pressure plate is fixedly connected to the bottom of the sleeve.

[0008] Preferably, a third guide rod is fixedly connected to the top of both ends of the pressure plate. The third guide rod is provided with scale lines, passes through the guide plate, and is slidably connected to the guide plate.

[0009] Preferably, a fixing plate is fixedly connected to one side of the mounting bracket, a motor is fixedly connected to the fixing plate, a drive screw is provided on one side of the fixing plate, and the drive screw is connected to the output end of the motor through a coupling.

[0010] Preferably, a screw nut is sleeved on the drive screw, the screw nut is adapted to the drive screw, and a sleeve plate is fixedly connected to the outer wall of the screw nut, the sleeve plate being fixedly connected to the top of the movable seat.

[0011] Preferably, each of the two ends of the movable base is fixedly connected to a movable plate, and each of the two movable plates is provided with a fourth guide rod. The movable plates are slidably connected to the fourth guide rods, and the two fourth guide rods are fixedly connected to the mounting bracket.

[0012] The beneficial effects of this utility model are as follows:

[0013] By employing a technique that allows the friction pad and pressure plate to descend during the movement of the friction pad, the descending pressure plate can press and fix the cardboard, while the friction pad also contacts the cardboard and applies a certain pressure. Continuing to move the friction pad laterally allows for abrasion resistance testing of the cardboard. Moving the roller to the other end of the guide plate allows the pressure plate and friction pad to rise, enabling the cardboard to be removed after testing. This effectively solves the problem mentioned in the background technology that traditional methods of abrasion resistance testing of cardboard require manual operation for each test, which is time-consuming and labor-intensive. Especially with a large number of samples, continuous manual pressure and scraping may cause fatigue and affect the test results. This technology achieves a simple operation, facilitates abrasion resistance testing of cardboard, and effectively avoids workers applying pressure by hand for a long time, reducing labor intensity and fatigue risks.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6A surface abrasion resistance tester includes a tray 1, a movable seat 2 on the top of the tray 1, fixed shafts 3 fixedly connected to both sides of the movable seat 2, rollers 4 sleeved on the fixed shafts 3, the rollers 4 rotatably connected to the fixed shafts 3, a guide plate 5 on one side of the rollers 4, first guide rods 6 fixedly connected to the top of both ends of the guide plate 5, a mounting frame 26 fixedly connected to the top of the tray 1, the first guide rods 6 passing through the mounting frame 26 and slidably connected to the mounting frame 26, and four springs 7 on the top of the mounting frame 26, the four springs 7 respectively sleeved on four... A first guide rod 6 is provided, and a guide hole 27 is provided at the position of the first guide rod 6. The first guide rod 6 is set in the guide hole 27. A pressure plate 9 is provided at the bottom of the guide plate 5. An adjustment mechanism 8 for adjusting the height of the pressure plate 9 is provided on the guide plate 5. Two fixed rods 10 are fixedly connected to one side of the movable seat 2. The two fixed rods 10 are fixedly connected to the same L-shaped plate 11. Two second guide rods 12 are passed through the L-shaped plate 11. The second guide rods 12 are slidably connected to the L-shaped plate 11. The bottom of the two second guide rods 12 is fixedly connected to the same horizontal plate. 13. A friction pad 14 is fixedly connected to the bottom of the horizontal plate 13. Slider 15 is fixedly connected to both sides of the horizontal plate 13. The two pressure plates 9 have grooves 16 on their adjacent sides. The slider 15 is set in the groove 16 and slides to connect the pressure plate 9. Due to the technical means of moving the friction pad, the friction pad and the pressure plate can be lowered. Therefore, the pressure plate can press and fix the cardboard when it is lowered. At the same time, the friction pad will also contact the cardboard and apply a certain pressure to the cardboard. Continuing to move the friction pad laterally can perform abrasion resistance testing on the cardboard. Moving the roller to the other end of the guide plate can raise the pressure plate and the friction pad, and the cardboard after the test can be taken out. This effectively solves the problem that the traditional method of abrasion resistance testing of cardboard boxes requires manual operation for each test, which is time-consuming and labor-intensive. Especially when there are a large number of samples, continuous pressure and scraping by hand may cause fatigue and affect the test results. Thus, it achieves the technical effect of simple operation, convenient abrasion resistance testing of cardboard boxes, and effectively avoids the staff from applying pressure by hand for a long time, reducing labor intensity and fatigue risk.

[0023] In this utility model, the adjusting mechanism 8 includes a threaded sleeve 801, which passes through the guide plate 5 and is fixedly connected to the guide plate 5. A threaded rod 802 passes through the threaded sleeve 801 and is adapted to the threaded sleeve 801. A knob 803 is fixedly connected to the top of the threaded sleeve 801, and a rotating shaft 806 is fixedly connected to the bottom of the threaded rod 802. A sleeve 807 is fitted onto the rotating shaft 806, and the rotating shaft 806 is rotatably connected to the sleeve 807. The top of the pressure plate 9 is fixedly connected to the bottom of the sleeve 807. By turning the knob 803, the knob 803 will drive the threaded rod 802 to rotate, thereby adjusting the height of the threaded rod 802. The change in the height of the threaded rod 802 can adjust the height of the rotating shaft 806 and the sleeve 807, and thus adjust the initial height of the pressure plate 9.

[0024] In this utility model, a third guide rod 17 is fixedly connected to the top of both ends of the pressure plate 9. The third guide rod 17 is provided with a scale line 18. The third guide rod 17 passes through the guide plate 5. When the pressure plate 9 moves up and down, the third guide rod 17 will drive the third guide rod 17 to move along the guide plate 5, ensuring the stability of the pressure plate 9 when it moves up and down. The distance between the bottom of the pressure plate 9 and the support plate 1 is determined by the scale line 18, which makes it easy to confirm the initial distance between the two pressure plates 9 and the top of the support plate 1.

[0025] In this utility model, a fixing plate 19 is fixedly connected to one side of the mounting bracket 26, a motor 20 is fixedly connected to the fixing plate 19, a drive screw 21 is provided on one side of the fixing plate 19, and the drive screw 21 is connected to the output end of the motor 20 through a coupling.

[0026] In this utility model, a screw nut 22 is sleeved on the drive screw 21. The screw nut 22 is adapted to the drive screw 21. A sleeve plate 23 is fixedly connected to the outer wall of the screw nut 22. The sleeve plate 23 is fixedly connected to the top of the movable seat 2.

[0027] In this utility model, the top of both ends of the movable seat 2 are fixedly connected to movable plates 24, and a fourth guide rod 25 is passed through each of the two movable plates 24. The movable plates 24 are slidably connected to the fourth guide rods 25, and the two fourth guide rods 25 are fixedly connected to the mounting bracket 26. When the movable seat 2 moves, it will drive the movable plates 24 to move along the fourth guide rods 25, so as to ensure the stability of the movable seat 2 when moving laterally.

[0028] Working principle: Place the unassembled cardboard boxes on pallet 1, which is positioned at the bottom of the two pressure plates 9. An external power supply is used. Starting motor 20 causes the output of motor 20 to rotate the coupling, which in turn rotates the drive screw 21. Drive screw 21 then moves screw nut 22, which in turn moves sleeve 23. Sleeve 23 moves moving seat 2, which in turn moves fixed shaft 3. Fixed shaft 3 then moves roller 4. When roller 4 contacts guide plate 5 and continues to move laterally, it presses against guide plate 5, causing it to descend. The descent of guide plate 5 causes the first guide rod 6 to descend, which in turn compresses spring 7, causing it to contract. The descent of guide plate 5 then causes threaded sleeve 801 to descend, which in turn causes threaded rod 802 to descend, which in turn drives rotating shaft 802. As the rotating shaft 806 descends, the sleeve 807 descends, which in turn causes the pressure plate 9 to descend, bringing the two pressure plates 9 into contact with the cardboard and pressing it down to secure it. During the movement of the movable seat 2, the fixed rod 10 also moves, which in turn moves the L-shaped plate 11. The L-shaped plate 11 then moves the second guide rod 12, which in turn moves the horizontal plate 13. The horizontal plate 13 then moves the friction pad 14 and the slider 15. The slider 15 moves within the groove 16. Because the pressure plate 9 descends a certain distance, this descent causes the slider 15 to descend, which in turn causes the horizontal plate 13 to descend. The horizontal plate 13 then causes the second guide rod 12 to descend along the L-shaped plate 11. The descent of the horizontal plate 13 also causes the friction pad 14 to descend. While the pressure plate 9 is pressing down on the cardboard, the friction pad 14... It will also come into contact with the cardboard. At this time, the moving seat 2 continues to move laterally, so that the friction pad 14 can rub against the surface of the cardboard. Observe the position after friction to test the abrasion resistance of the cardboard. When the roller 4 moves from one end of the guide plate 5 to the other end, the contracted spring 7 will extend, so that the first guide rod 6 can rise, which can also raise the guide plate 5. When the guide plate 5 rises, the pressure plate 9 will also rise and no longer press and fix the cardboard. The cardboard can then be taken out, and the abrasion resistance test of the cardboard can be continued according to the same steps.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
