Description

Technical Field

[0001] The present invention relates to the technical field of simulation testing, and in particular to a transport packaging simulation testing box and a use method thereof. Background Art

[0002] Packaging and transportation testing is a professional product packaging simulation transportation test. It aims to conduct comprehensive testing and evaluation of product packaging by simulating the actual transportation environment. It uses advanced testing equipment and technology to conduct rigorous testing of product packaging from multiple angles such as vibration, impact, and drop to ensure that the product can safely reach consumers during the actual transportation process.

[0003] Announcement No. CN221685848U discloses a simulation test device for transporting and handling outdoor products after packaging. The staff puts the packaged product on a rectangular plate, and then the controller starts the second motor. The rotating plate rotates with the electric push rod. When the electric push rod passes through the opening, the controller turns off the second motor and then turns on the electric push rod. The movable end of the electric push rod pushes up a corner of the packaged product, and the packaged product falls from the rectangular plate at an angle. This allows the corner of the packaged product to touch the ground first. Then the staff checks the appearance again and repeats the above steps until all corners are tested. The full range of detection improves the accuracy of the detection results. However, the above patent still has the following problems in actual use:

[0050] Working principle: Before using this transport packaging simulation test box and its usage method, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11 As shown, first, the test cylinder 101 is used to drive the clamping bracket 102 to move up and down, and the humidifier 106 and the heater 107 are used to humidify and heat the interior of the entire test box, and the product is placed in a specific temperature and humidity environment to check the performance of the product and the integrity of the packaging under different temperature and humidity conditions. The clamping motor 109 is started to drive the first sprocket transmission assembly 110 and the clamping bidirectional threaded rod 111 to rotate, so that the clamping threaded sleeve 112 drives the clamping limit plate 113 and the fixed support 114 to move relatively, so that the top of the clamping plate 117 contacts the top of the product, and under the action of the second clamping rotating rod 123 and the rotating support 116, the clamping plate 117 is rotated, and at the same time, the second clamping rotating rod 123 drives the clamping sliding sleeve 121 to move between the clamping sliding rod 120 The outer side of the clamping plate 117 is slid and the clamping spring 122 is squeezed. The packaged product can be stably clamped and fixed by means of the compression spring 118 and the protective sticker 119. The packaged product is raised to different heights and the clamping plate 117 is released. Under the elastic force of the clamping spring 122, the clamping plate 117 rotates and the packaged product is pushed downward through the top to accelerate the fall. The product falls from different heights onto a rigid plane to evaluate the ability of the product and the package to withstand the impact of falling. At the same time, the pressure test block 124 can be clamped by the clamping plate 117, and multiple packaged products can be stacked together. A certain vertical pressure is applied to simulate the stacking of products during warehousing and transportation to determine the maximum stacking pressure that the package can withstand, thereby adapting to packaging and transportation simulation tests with different needs.

Under the action of the connecting hinge 225, the unfolding side plate 226 can be unfolded and closed, which is not only convenient for the rapid placement of the inspected items, but also the rapid ventilation of the test box after the test is completed, which is convenient for subsequent inspections.

[0052] Finally, the box base 201 and the test box can be supported by the vertical support spring 227, the buffer rotation rod 232 and the transverse spring 233. The reciprocating motor 235 is started to drive the reciprocating worm 236 to rotate.
