Description

A drop machine with adjustable test bench height

technical field

The utility model relates to a test equipment for cosmetics, more specifically, it relates to a drop machine which can adjust the height of the test table.

Background technique

After a product is packaged, it may be dropped during the handling process, and the resulting impact will damage the product. Therefore, general manufacturers will conduct drop tests on packaged items. As far as the cosmetics industry is concerned, there are two methods for testing packaged cosmetics: the first is to drop the package at a height of 30cm for 3 times; the second is to drop it at a height of 100cm for 1 time.

At present, there is a drop machine for testing cosmetics on the market, including a bottom frame, corresponding brackets placed on both sides of the bottom frame, a test bench placed between the two brackets and parallel to the horizontal plane, and a test bench placed 30cm or 100cm above the test bench. Bracket, the bracket is controlled by the cylinder, and set storage holes above the bracket 30cm and 100cm away from the test bench for installing the cylinder. During the test, place the packaged test piece on the bracket, and then start the cylinder to quickly separate the bracket from the packaged test piece. The packaged test piece falls vertically to the test platform due to inertia. If the packaged test piece is intact, it means that the product is qualified. , otherwise, the product is unqualified.

However, a drop machine is often equipped with only one bracket, and when the height needs to be adjusted, it is often necessary to disassemble the original bracket and install it at another height. In this way, because the bracket is connected to the cylinder, it needs to be disassembled together with the cylinder. The cylinder is relatively heavy and is connected to the air pump through the air pipe, so there are many and cumbersome things to disassemble.
