Description

technical field

[0001] The invention relates to the technical field of rubber bark detection, in particular to a rubber bark cutting device for tensile and shear strength tests. Background technique

[0002] At present, in testing the tensile properties and shear strength of rubber tree bark, it is necessary to test the mechanical parameters of the fresh bark of rubber tree. Width 3-5cm, use a cutting knife to cut two parallel cuts along the trunk direction, and then cut two cuts along the circumference of the trunk, and finally remove the bark with a tool, immediately wrap it in a wet cloth and put it in a refrigerator. Stay hydrated. At present, the cutter cutting resistance adopted when cutting the bark along the trunk direction is large. For example, the Chinese patent with the publication number CN106105801A is a bark cutting device for Eucommia ulmoides, which uses the cutter to move in the track to cut the bark. When cutting the bark along the trunk direction, the c...
