Description

Technical Field

[0001] This utility model relates to the field of drop testing machine technology, specifically a carton drop testing machine. Background Technology

[0002] In the packaging and transportation industry, cardboard boxes are one of the most commonly used packaging containers, and their quality directly affects the safety of products during transportation and storage. Drop testing is an important means of evaluating the compression and impact resistance of cardboard boxes. By simulating the drop scenarios that cardboard boxes may encounter during transportation, the degree of damage to the cardboard box and its internal products is detected, thereby ensuring that the cardboard box design is reasonable and the quality is reliable.

[0003] However, existing carton drop testers have many limitations in practical applications. On the one hand, the structural design of traditional testers is often relatively fixed, lacking flexibility and making it difficult to adapt to the testing needs of cartons of different sizes and shapes. This necessitates changing different testing equipment or making complex adjustments when testing cartons of different specifications, increasing testing costs and time, thus affecting the accuracy and comprehensiveness of the test results. On the other hand, the drop performance of a carton is not only related to its own structure but also affected by factors such as the material and hardness of the drop surface. Traditional testers typically only provide a single drop surface and cannot simulate ground environments with different materials and hardnesses, making it difficult for test results to fully reflect the performance of the carton in actual transportation. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a carton drop tester, which can effectively solve the technical problems of poor versatility and inability to provide various landing environments for testing currently used for carton drop testers.

[0028] 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.

[0029] like Figure 1-5 As shown, this utility model provides a carton drop tester, which simulates the conditions of a carton 26 falling from different heights to test the compression resistance, impact resistance and other properties of the carton 26.

[0030] The structure of the carton drop tester includes an impact table 1 for forming the impact surface. A recessed receiving groove 101 is formed on the impact table 1. Material shelves 3 are laid flat within the receiving groove 101. After the material shelves 3 are laid flat, they are fixed by shelf locking components 16 installed around the perimeter. The shelf locking components 16 can use common fixing methods such as bolts or clips to ensure that the material shelves 3 are stably installed within the receiving groove 101, providing a stable support foundation for the carton 26 during drop testing. Furthermore, the material shelves 3 can be made of different materials to form impact surfaces with different performance characteristics for testing.

[0031] A vertically fixed upright 2 is provided on the impact table 1, and a rack 17 is fixedly connected to one side of the upright 2 along its length. A movable component 4 is sleeved on the outside of the upright 2, and a gear component 18 that meshes with the rack 17 is provided on the inside of the movable component 4. The movable component 4 is adjusted to different heights on the upright 2 by a lifting drive assembly 5. The lifting drive assembly 5 consists of a worm gear reducer 501 fixed on the movable component 4 and a lifting drive motor 502. The output end of the worm gear reducer 501 passes through the movable component 4 and is coaxially connected to the gear component 18, while the input end of the worm gear reducer 501 is connected to the output end of the lifting drive motor 502. When the lifting drive motor 502 is working, the gear component 18 moves on the rack 17 in conjunction with the worm gear reducer 501, thereby adjusting the height of the movable component 4 and realizing the lifting and lowering movement of the movable component 4 on the upright 2.

[0032] The top of the movable component 4 is provided with two vertically fixed support rods 6. The top of the support rods 6 is connected to an upper crossbar 8 extending upwards towards the material shelf 3 via a first connector 7. The bottom of the support rods 6 is connected to a side crossbar 12 extending laterally after being bent via a third connector 11. The end of the upper crossbar 8 away from the support rods 6 is connected to a downwardly extending front stop bar 10 via a second connector 9. The front stop bar 10, the upper crossbar 8, and the side crossbar 12 together form a frame that restricts the horizontal movement of the carton 26.

[0033] The first connector 7, the second connector 9, and the third connector 11 each have two mutually perpendicular and staggered first adjustment holes 19, and are equipped with first adjustment locking parts 20 that are used in conjunction with the corresponding first adjustment holes 19. By cooperating with the first adjustment locking parts 20 in different positions with the first adjustment holes 19, the relative positions of the upper crossbar 8, the front stop bar 10, and the side crossbar 12 can be adjusted to meet the testing requirements of cartons 26 of different sizes.

[0034] A limiting block 14 is provided on the upper crossbar 8 to limit and fix the edges of the carton 26. The limiting block 14 has a second adjustment hole 21 that can slide and adjust its position on the upper crossbar 8. The limiting block 14 also has a second adjustment locking member 22 that works in conjunction with the second adjustment hole 21. By cooperating with the second adjustment hole 21, the position of the limiting block 14 on the upper crossbar 8 can be adjusted to meet the limiting requirements of the edges of cartons 26 of different sizes. A right-angle groove 1401 is provided on one side of the limiting block 14 for positioning the carton 26. The right-angle groove 1401 can more accurately position the carton 26 and ensure the positional accuracy of the carton 26 during testing.

[0035] The bottom of the movable component 4 is connected to a base plate 13 extending upwards from the material shelf 3. One end of the base plate 13 is movably connected to the movable component 4. Specifically, the base plate 13 is connected to one end of the movable component 4 via a movable rod 23. One end of the movable rod 23 is fixed to the bottom of the base plate 13, and the other end of the movable rod 23 is riveted to the movable component 4, allowing the base plate 13 to move horizontally. A side-pulling cylinder 15 is provided on the movable component 4 to control the movement of the base plate 13 outwards from the side crossbar 12. When the side-pulling cylinder 15 is working, it can push the base plate 13 to move horizontally, facilitating the placement and floor testing of the carton 26.

[0036] The impact table 1 is also equipped with an electrical control box 24, on which a human-machine interface 25 is provided. The human-machine interface 25 can be used to set test parameters, such as lifting height and number of drops, and to display relevant data during the test, facilitating the operator's control and monitoring of the testing machine.

[0037] In use, select a suitable material shelf 3, install it in the receiving slot 101, and fix it with the shelf locking member 16. According to the size of the carton to be tested, adjust the relative positions of the upper crossbar 8, front stop bar 10, and side crossbar 12 using the first adjusting locking member 20, and adjust the position of the limiting block 14 on the upper crossbar 8 using the second adjusting locking member 22, so that the space for placing the carton and the position of the limiting block 14 are suitable for the carton to be tested. Activate the side-pulling cylinder 15 to push the base plate 13 outwards from the side crossbar 12, placing the carton to be tested in the space formed by the upper crossbar 8, front stop bar 10, side crossbar 12, and base plate 13, so that the edges of the carton fit against the right-angle groove 1401 of the limiting block 14, achieving precise positioning of the carton. Then, the side-pulling cylinder 15 resets, driving the base plate 13 back to its original position. Set test parameters such as lifting height and number of drops through the human-machine interface 25. The lifting drive motor 502 operates, which, through the worm gear reducer 501, controls the gear component 18 to move on the rack 17, raising and lowering the movable part 4 to the set height. Then, the bottom plate 13 is removed from the carton, causing the carton to fall from the set height onto the material shelf 3, completing one drop test. The above lifting and dropping process is repeated until the set number of drops is reached.

[0038] Compared with traditional technologies, the carton drop tester provided by this technical solution has a simple structure, is easy to operate, and can be adjusted to accommodate cartons 26 of different sizes. Moreover, the cartons 26 can be set at different heights for drop testing, making it highly versatile. In addition, users can replace the material shelves 3 of different materials to create different testing environments, effectively testing the performance of the cartons.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
