The invention provides a detection device and a detection method for the abrasion resistance of aluminized films, belonging to the technical field of abrasion resistance detection of aluminized films. The cylindrical friction piece is plugged with a central drive shaft, the central drive shaft is rotatably connected to the detection frame seat, the arc-shaped connecting seats are symmetrically distributed at both ends of the cylindrical friction piece, and the arc-shaped connecting seat and the central driving shaft are A linkage assembly is connected between the two, and the central drive shaft is used to drive the cylindrical friction piece to rotate while driving the arc connecting seat to rotate through the linkage assembly, and a pressing and fixing part is symmetrically connected between the symmetrical arc connecting seats. The aluminized film coating wear resistance testing equipment and testing method effectively improve the speed of the sample wear resistance test, the stability of the sample when the sample is fixed, and the stability of the sample testing process, and at the same time, the friction detection mode can be replaced to meet different friction detection modes. , and can adjust and control the area where the sample is rubbed.

Description

technical field [0001] A kind of aluminized film coating wear resistance testing equipment and testing method [0002] The invention relates to the technical field of abrasion resistance detection of aluminized films, in particular to a detection device and a detection method of abrasion resistance of aluminized films. Background technique [0003] Aluminized film is a composite flexible packaging material formed by coating a layer of metal aluminum on the surface of plastic film. It has both the characteristics of plastic film and metal characteristics. It is a packaging material with excellent performance and strong practicability. In the process of use, it often rubs with the packaged object, so in the production process, it is necessary to select a certain sample to test the wear resistance of the aluminum coating to ensure its stability during use, and the sample is resistant to wear. The abrasion test mainly uses friction parts to rub the aluminum coating of the sampl...

AI Technical Summary

Problems solved by technology

[0004] There are mainly two methods for the existing wear resistance testing, one is that one of the friction parts and the sample remains stationary, the other generates friction through reciprocating motion, and the other is that both the friction parts and the sample are in motion, and one does The reciprocating motion in the opposite direction generates friction, and the two reciprocating motions in the same direction generate friction, which cannot continuously rub the sample area at the same position, which seriously reduces the efficiency of friction detection, and is affected by the characteristics of the plastic film. It is more difficult to control the fixation aspect, and the stability of the sample fixation is lower
