Description

Technical Field

[0001] This utility model relates to the field of corrugated paper packaging box technology, specifically a protective performance testing device for corrugated paper packaging boxes. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading.

[0003] The demand for corrugated cardboard boxes is increasing. Boxes of different materials are used for transporting different products. High-quality boxes can be used to transport fragile items, so their protective requirements are high. Currently, there is no special device to simulate the protective performance of cardboard boxes, so it is impossible to determine whether the protective performance of the box meets the requirements. We can only rely on simple manual testing, which is time-consuming and the results are inaccurate.

[0004] Therefore, it is necessary to design a practical and automated testing device for the protective performance of corrugated cardboard boxes. Utility Model Content

[0005] The purpose of this invention is to provide a protective performance testing device for corrugated cardboard boxes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective performance testing device for corrugated cardboard boxes, comprising a main body, a support frame above the main body, an enclosing ring above the support frame, a track inside the enclosing ring, a sleeve above the track, a limit rod slidably connected inside the sleeve, and a slider above the track, the slider being connected to the limit rod.

[0007] According to the above technical solution, the main body is provided with a first slide rail inside, a first threaded rod is provided on the inner side of the first slide rail, and a first control block is slidably connected above the first slide rail. The first control block and the first threaded rod are slidably connected to each other.

[0008] According to the above technical solution, a second slide is provided above the first control block, a second threaded rod is rotatably connected to the inner side of the second slide, a second control block is slidably connected above the second slide, and the second control block and the second threaded rod are threadedly engaged with each other.

[0009] According to the above technical solution, a first pulley group is rotatably connected to the outer side of the first control block, and the inner side of the first pulley group is threadedly engaged with the second threaded rod. A connecting plate is provided at the bottom of the second slide, and a second pulley group is provided on the outer side of the connecting plate. A third pulley group is provided on the outer side of the connecting plate. The first pulley group, the second pulley group, and the third pulley group are connected by belt drive.

[0010] According to the above technical solution, a helical gear set is provided on the rear side of the third pulley set, and the other end of the helical gear set is connected to the second threaded rod.

[0011] According to the above technical solution, a lifting platform is rotatably connected above the second control block, a spring is provided above the lifting platform, a magnetic bottom is provided above the spring, a cardboard box is provided above the magnetic bottom, and a magnetic head is provided on the inner side of the cardboard box.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) After the main body is set up and the position is adjusted by the limit rod, the worker opens the carton and places it on the magnetic bottom. Then the magnetic head is placed inside the carton. The magnetic head and the magnetic bottom attract each other, so that the carton is clamped in the middle and fixed. Then the elevator descends and drives the carton to descend into the main body. Then it follows the displacement of the second control block. The spring drives the carton to shake through inertia and finally hits the inner wall of the main body to simulate impact. The carton hits the inner corner of the main body multiple times. Then the elevator rotates and drives the carton to rotate. The impact simulation test continues on the other two opposite corners of the carton. Finally, the carton returns to its original position. The staff checks the damage of the carton and draws a protective conclusion. It is convenient and quick.

[0014] (2) By setting a belt, when the third belt pulley group rotates, it will drive the helical gear group to rotate and transmit the rotation to the second threaded rod so that it will rotate together, thereby causing the second control block to move on the second slide rail. When the first control block drives the second slide rail to move backward, the second control block moves to the left at the same time, achieving a linkage effect.

[0015] (3) By setting a limit rod, the slider and the limit rod are connected to each other. The slider can move back and forth on the track, which drives the limit rod to move back and forth, making it easier for workers to center the carton when placing it. The size of the carton can be adjusted according to its size, which facilitates the accuracy of subsequent inspection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a protective performance testing device for corrugated cardboard boxes, including a main body 1, a support frame 2 above the main body 1, an enclosing ring 3 above the support frame 2, a track 6 inside the enclosing ring 3, a sleeve 4 above the track 6, a limiting rod 7 slidably connected inside the sleeve 4, a slider 8 above the track 6, the slider 8 and the limiting rod 7 are interconnected, the slider 8 can move back and forth on the track 6, driving the limiting rod 7 to move back and forth, so that workers can easily center the cardboard box 5 when placing it, and adjust it according to the size of the cardboard box 5, which facilitates the accuracy of subsequent testing;

[0022] The main body 1 has a first slide rail 10 inside, a first threaded rod 12 inside the first slide rail 10, and a first control block 13 slidably connected above the first slide rail 10. The first control block 13 and the first threaded rod 12 are slidably connected to each other. The first control block 13 can move back and forth within the first slide rail 10 to prepare for simulation testing.

[0023] A second slide rail 9 is provided above the first control block 13. A second threaded rod 11 is rotatably connected to the inner side of the second slide rail 9. A second control block 20 is slidably connected above the second slide rail 9. The second control block 20 and the second threaded rod 11 are threadedly engaged with each other. Rotating the second threaded rod 11 can drive the second control block 20 to move back and forth, in preparation for simulation testing.

[0024] The outer side of the first control block 13 is rotatably connected to the first pulley group 14. The inner side of the first pulley group 14 is threadedly engaged with the second threaded rod 11. The bottom of the second slide rail 9 is provided with a connecting plate 16. The outer side of the connecting plate 16 is provided with the second pulley group 17 and the outer side of the connecting plate 16 is provided with the third pulley group 18. The first pulley group 14, the second pulley group 17 and the third pulley group 18 are connected by a belt 15. When the first control block 13 slides backward, it will drive the first pulley group 14 to follow the displacement. By using the internal threaded engagement, it will be driven to rotate by the first threaded rod 12, thereby driving the second pulley group 17 and the third pulley group 18 to follow the displacement through the belt 15, realizing linkage, and preparing for simulation test.

[0025] A helical gear set 19 is provided on the rear side of the third pulley set 18. The other end of the helical gear set 19 is connected to the second threaded rod 11. When the third pulley set 18 rotates, it will drive the helical gear set 19 to rotate and transmit the rotation to the second threaded rod 11 so that it will rotate together. This causes the second control block 20 to move on the second slide rail 9. When the first control block 13 drives the second slide rail 9 to move backward, the second control block 20 moves to the left at the same time, achieving a linkage effect.

[0026] A lifting platform 21 is rotatably connected above the second control block 20. A spring 22 is installed above the lifting platform 21, and a magnetic base 23 is installed above the spring 22. A cardboard box 5 is installed above the magnetic base 23, and a magnetic head 24 is installed inside the cardboard box 5. After the limit rod 7 is adjusted to the correct position, the worker opens the cardboard box 5 and places it on the magnetic base 23. Then, the magnetic head 24 is placed inside the cardboard box 5. The magnetic head 24 and the magnetic base 23 attract each other, clamping the cardboard box 5 in the middle for a fixed effect. Then, the lifting platform 21 descends, causing the cardboard box 5 to descend into the main body 1. It then moves with the second control block 20. The spring 22 causes the cardboard box 5 to shake due to inertia and eventually hit the inner wall of the main body 1, simulating an impact. The impact is repeated on the inner corner of the main body 1. Afterward, the lifting platform 21 rotates, causing the cardboard box 5 to rotate, and the impact simulation test is continued on the other two opposite corners of the cardboard box 5. Finally, the cardboard box 5 returns to its original position, and the staff checks the degree of damage to the cardboard box 5 to draw a protective conclusion. This process is convenient and quick.
