Wooden Box Packaging Drop Impact Tester - Analysis

This article will provide a detailed introduction to the working principle and testing steps of the DLJ-2000 paper box drop tester for Sanquan Zhongshi, as well as how to conduct accurate testing according to the GB/T 4857.5 standard.

Wooden box packaging drop impact testerTest principle

The working principle of the DLJ-2000 cardboard box drop tester is based on the principle of free fall. By precisely controlling the lifting of the test sample to a predetermined height, it falls freely and impacts the impact table, simulating the possible drop situations that packaging may encounter during transportation. This test aims to evaluate the load-bearing capacity and integrity of packaging materials and their internal products, ensuring that they can effectively protect the products from damage during the actual logistics process.

Wooden box packaging drop impact testerTest steps

According to the GB/T 4857.5 standard, the DLJ-2000 paper box drop tester for Sanquan Zhongshi

Wooden box packaging drop impact testerThe specific experimental steps are as follows:

1. Lift the test sample to the predetermined height: Accurately lift the test sample to the desired drop height position and secure it with appropriate support devices. Ensure that the difference between the lifting height and the predetermined height does not exceed ± 2% of the predetermined height. The drop height refers to the vertical distance between the point of the test sample and the impact table when preparing for release.

2. Release the test sample according to the predetermined state:

Surface drop: Ensure that the maximum angle between the drop surface of the test sample and the horizontal plane does not exceed 2 °, to simulate the scenario of the package landing on a flat surface.

Edge drop: Ensure that the angle between the dropped edge and the horizontal plane does not exceed 2 °, and that the error in the angle between the specified surface on the test sample and the impact table surface is not greater than ± 5 ° or 10% of this angle (whichever is greater), to ensure that the gravity line passes through the dropped edge.

Angle drop: The angle error between the surface and the impact table shall not exceed ± 5 ° or 10% of this angle (whichever is greater), ensuring that the gravity line passes through the dropped angle.

Regardless of the falling state, it should be ensured that the gravity line of the test sample passes through the dropped surface, line, and point to simulate the impact under the most unfavorable conditions.

3. Control the impact speed:

The difference between the actual impact velocity and the theoretical impact velocity during free fall should not exceed ± 1% of the free fall to ensure the accuracy of the test results.

4. Conduct a drop test:

Release the test sample according to the predetermined drop method and allow it to freely fall onto the impact table.

5. Inspection and analysis:

After the experiment is completed, carefully inspect the packaging and contents for damage according to relevant standards or regulations, including but not limited to deformation, rupture, leakage, etc.

Analyze the test results, evaluate the impact resistance strength of the packaging and the rationality of the design, and propose improvement suggestions.
