Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboard strength testing devices, in particular to a corrugated paperboard bonding strength peeling frame. Background Art

[0002] At present, corrugated cardboard must be tested for bonding strength in accordance with GB / T 6548-2011 "Determination of bonding strength of corrugated cardboard" before leaving the factory. The current testing equipment has the following disadvantages when testing bonding strength:

[0003] 1) The common peeling frame is a customized peeling frame. When testing the bonding strength of corrugated cardboards of different specifications, the peeling frame of the corresponding model needs to be replaced;

[0004] 2) Due to the extrusion or production of corrugated cardboard when stacked together, the gap spacing in the corrugated cardboard will change. Since the pin spacing of the current equipment cannot be adjusted, the pins may be unequally spaced after insertion, and the pin body will be unevenly stressed during the test;

[0005] 3) When the existing peeling frame is used for the bonding strength test, the sample placement may be deviated due to the lack of a sample placement platform, which may cause uneven force on the cardboard part and affect the test effect;

[0006] 4) In the existing stripping frame, the short pins are pressure pins and the long pins are support pins. Before testing, the pressure pins and support pins need to be inserted into the gaps of the corrugated cardboard in sequence. If the order of pin insertion is wrong, the order needs to be readjusted to insert the pins, which prolongs the test time. Utility Model Content
