Technical Field
[0001] This utility model relates to the field of cardboard box testing technology, and in particular to a testing device for moisture-proof cardboard boxes. Background Technology
[0002] Cardboard boxes are common everyday storage items. They are made by folding and assembling cardboard to form a box structure for storing items. In actual use, cardboard boxes may be used for long-term storage and in humid climates. Therefore, by upgrading materials and improving cardboard manufacturing processes, it is possible to make moisture-proof cardboard boxes with stronger moisture-proof functions.
[0003] Cardboard boxes are frequently handled during use, and during this process, accidents can happen that cause them to fall to the ground. If the cardboard box is not strong enough, it may be damaged when it falls. Therefore, drop testing is necessary. Existing drop testing devices typically include a platform for placing the cardboard box and a pusher to push it down. During testing, the pusher pushes the cardboard box off the platform to perform the drop test.
[0004] However, in actual use, cardboard boxes are not necessarily laid flat when they fall. The contents inside may affect the overall center of gravity, causing the cardboard box to flip over during the fall and land on its corners. Existing cardboard box drop detection devices cannot detect the drop intensity of the cardboard box corners, and the detection angle is not comprehensive enough. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0031] This application discloses a detection device for moisture-proof cardboard boxes. (Refer to...) Figure 1The device includes a base 1, a drop bar 2, and an auxiliary bar 3. A lifting frame 11 is fixedly mounted on the base 1. A lifting column 12 is vertically mounted on the lifting frame 11, and a lifting block 4 is slidably fitted onto the lifting column 12. A lifting assembly 5 is provided on the lifting frame 11 to adjust the lifting block 4. The drop bar 2 is rotatably mounted on the bottom wall of the lifting block 4 via a rotating shaft. A drop block 21 is fixedly mounted at the end of the drop bar 2 to hold a cardboard box. A lifting motor 51 is fixedly mounted on the outer wall of the lifting block 4 as a rotating component, and the rotating shaft of the lifting motor 51 is fixedly connected to the rotating shaft of the drop bar 2. The auxiliary bar 3 is slidably mounted on the lifting block 4. A locking assembly 6 is provided on the lifting block 4 to lock the auxiliary bar 3, and an auxiliary block 31 is fixedly mounted at the end of the auxiliary bar 3 to support the cardboard box. By locking the auxiliary rod 3 and auxiliary block 31 after they move, the auxiliary block 31 and the drop block 21 fix the carton from the top and bottom, so that the carton can be fixed on the drop block 21 with the corners facing down. Then, the drop rod 2 is rotated to make the carton fall, so that the structural strength of the corners of the carton can be tested, and the comprehensiveness of the test can be improved.
[0032] For ease of use, please refer to Figure 1 The lifting assembly 5 includes a lifting motor 51 and a lifting screw 52. The lifting screw 52 is rotatably mounted on the lifting frame 11 in a vertical direction, and its thread passes through the lifting block 4. The lifting motor 51 is fixedly mounted on the base 1, and its shaft is coaxially and fixedly connected to the lifting screw 52. After the lifting motor 51 is started, it drives the lifting screw 52 to rotate, thereby causing the lifting block 4 to rise and fall, changing the height of the drop block 21. This allows the equipment to test the carton's drop performance at different heights, improving the comprehensiveness of the inspection.
[0033] To improve applicability, refer to Figure 1 and Figure 2A cylindrical first sliding rod 41 is fixedly installed vertically on the top wall of the lifting block 4. A sliding block 42 is slidably mounted on the first sliding rod 41, and the sliding block 42 can rotate on the first sliding rod 41. A first sliding bolt 421, which can abut against the first sliding rod 41, is threaded onto the sliding block 42. A first sliding handle 422 is fixedly sleeved on the first sliding bolt 421. After the first sliding bolt 421 is tightened, it abuts against the first sliding rod 41, thereby locking the rotation and sliding of the sliding block 42 on the first sliding rod 41. A second sliding rod 43 is slidably mounted through the sliding block 42, and the second sliding rod 43 is set horizontally. An auxiliary rod 3 is slidably connected to the second sliding rod 43. A second sliding bolt 423 is threaded onto the sliding block 42. After the second sliding bolt 423 is tightened, it abuts against the second sliding rod 43 for locking. A second sliding handle 424 is fixedly sleeved on the second sliding bolt 423. By sliding the sliding block 42 with the first sliding rod 41 and the second sliding rod 43, the position of the auxiliary rod 3 and the auxiliary block 31 can be adjusted, making the device suitable for cartons of different sizes and able to fix the cartons on the drop block 21 in different postures, thus improving its applicability.
[0034] For ease of use, please refer to Figure 1 and Figure 2 The locking assembly 6 includes a locking block 61 and a locking bolt 62. The locking block 61 is slidably mounted on the second sliding rod 43. The auxiliary rod 3 is vertically positioned and slides through the locking block 61. The locking bolt 62 is threadedly connected to the locking block 61 and can abut against the auxiliary rod 3. A locking handle 621 is fixedly mounted on the locking bolt 62. A fixing bolt 431 is rotatably mounted on the locking block 61. After the fixing bolt 431 is rotated and tightened, it can abut against the second sliding rod 43, thereby locking the sliding between the second sliding rod 43 and the sliding block 42. A fixing handle 432 is fixedly mounted on the fixing bolt 431. After the auxiliary rod 3 slides, rotating the locking handle 621 causes the locking bolt 62 to abut against the auxiliary rod 3, thus completing the locking. The operation is simple and convenient.
[0035] To improve ease of use, refer to Figure 1 The device is also equipped with a control box 13, which contains a controller that is signal-connected to both the rotating motor 22 and the lifting motor 51. The buttons on the surface of the control box 13 are signal-connected to the controller and are used to control the opening and closing of the lifting motor 51 and the rotating motor 22, thereby further improving the ease of use.
[0036] The implementation principle of the moisture-proof cardboard box detection device in this application embodiment is as follows: The cardboard box is placed on the drop block 21, and the rotating motor 22 is started to drive the drop rod 2 to rotate, so that the drop block 21 is detached from the bottom of the cardboard box. After the cardboard box loses its support, it falls, and a drop test is performed. At the same time, this device can also be used to detect the drop situation of the corner of the cardboard box. The cardboard box is placed on the drop block 21 with the corner of the cardboard box abutting against the surface of the drop block 21. Then, the sliding block 42 is driven to rotate and slide, and the auxiliary rod 3 is driven to move so that the auxiliary block 31 presses against the surface of the cardboard box. Then, all the bolts are tightened to complete the overall fixation. The cardboard box is fixed by the auxiliary block 31 and the drop block 21. Then, the rotating motor 22 is started to drive the drop rod 2 to rotate, so that the drop block 21 is detached from the bottom of the cardboard box. After the cardboard box loses its support, it falls, and the corner of the cardboard box touches the ground first, completing the corner drop test. Compared with the existing technology, which can only perform drop tests on flat cardboard boxes, this application improves the comprehensiveness of the detection.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
