Description

Technical Field

[0001] This utility model belongs to the field of packaging testing technology, specifically relating to a throwing test device for transport packaging. Background Technology

[0002] In the field of packaging testing, free fall is commonly used to test the drop scenarios of express delivery packages. While this method is convenient for laboratory testing, it differs significantly from actual transportation scenarios. According to actual surveys within the express delivery industry, most drops during transit are not free falls, but rather drops caused by being tossed or thrown. These drops are distinctly different from free falls.

[0003] Therefore, in order to better reflect actual logistics scenarios and reproduce the hazards of logistics, it is necessary to apply a new type of testing equipment to better test the degree of harm of packaging during the throwing process and to reasonably judge the safety of packaging. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a throwing test device for transport packaging.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A throwing test device for transport packages includes a rigid ground. Support legs are symmetrically fixedly installed on one side of the rigid ground. A lifting transmission unit is installed on the support legs. A lifting platform is fixedly installed on the lifting transmission unit. A pneumatic booster is installed on the lifting platform. The pneumatic booster is connected to an air compressor fixedly installed on the rigid ground via an air duct. Guide rails are symmetrically arranged at the front and rear ends of the lifting platform. The bottom end of the pneumatic booster is slidably installed on the guide rail via a guide rail slider. The booster plate at the front end of the pneumatic booster is driven by the pneumatic booster to push the package to be tested placed on the lifting platform, causing it to fall onto the rigid ground.

[0007] A control cabinet is installed below the lifting platform. The control cabinet is equipped with a display screen, a start button, and a stop button. The pneumatic booster and the air compressor are both connected to the control cabinet.

[0008] Furthermore, a laser velocimeter is fixedly installed on the side of the lifting platform via a support profile. The laser velocimeter records the initial throwing speed of the pneumatic booster in real time and is connected to the display screen.

[0009] Furthermore, a height gauge is installed on the outrigger.

[0010] Furthermore, several rollers are arranged side by side on the lifting platform, and the package to be tested is placed on the rollers.

[0011] Moreover, the lifting transmission unit is a lifting cylinder or a screw and gear rack transmission, and the screw is driven by a manual lifting handle located below the lifting platform.

[0012] Furthermore, the rigid floor is made of Q235 metal and meets the requirements of the packaging testing standard GB / T4857.5 Packaging Transport Package Drop Test Method.

[0013] The advantages and beneficial effects of this utility model are as follows:

[0014] 1. The device of this utility model has a clear structure and well-defined function. It is used for packaging throwing tests and can complete the throwing tests of the packaging under test with different throwing heights and different initial speeds. It has a wide range of applications.

[0015] 2. The support legs of this utility model are equipped with height scales, which can meet the throwing requirements at different heights.

[0016] 3. The test package of this utility model is pushed out by a pneumatic booster and a booster plate to complete the throwing and landing, and can achieve different initial throwing speeds.

[0017] 4. Several rollers are arranged side by side on the lifting platform of this utility model. The package to be tested is placed on the rollers. The rollers can rotate and provide stable initial support when the package to be tested is thrown out. Attached Figure Description
