[0030] In this embodiment, the pulp molded product sample material to be tested is clamped between the first clamping module and the second clamping module. There are multiple first clamping modules and second clamping modules, which can simultaneously detect multiple pulp molded product sample materials, thus achieving high detection efficiency.

Several second protrusions 15 are provided below the second movable clamping plate 11, and several second grooves 17 are provided at the bottom of the second U-shaped clamping plate 7 opposite to the second protrusions 15.

The first tension sensor 12 and the second tension sensor 13 sense the tension on the pulp molded product sample material. When the pulp molded product sample material breaks, the current value is recorded.
[0037] When testing the compressive strength of molded pulp products, the molded pulp product to be tested is placed under the pressure plate 20, and the extrusion cylinder 19 moves downward to slowly increase the pressure, so that the pressure plate 20 extrudes the molded pulp product. When the pressure value sensed by the pressure sensor 21 suddenly changes, the value is recorded.
