Abstract

[0002] During the production of PP hollow boards, it is often necessary to measure the load-bearing capacity of the boards, and tensile strength is one of the important values.
[0003] However, conventional tensile testing generally involves fixing both ends of a hollow board and pulling one end in a straight line until it breaks, thereby determining the limit value of the board's tensile force.

Therefore, how to better simulate the stress and load-bearing situation in the middle of a hollow board is a problem that urgently needs to be solved. To this end, this utility model proposes a tensile testing device for hollow board quality inspection. Utility Model Content
