Rubber tree bark cutting device for tensile and shear strength tests

Abstract

The invention discloses a rubber tree bark cutting device for tensile and shear strength test. The device comprises hoops, a linear slide rail, an arc-shaped slide rail, a cutting knife and a handle, wherein the hoops are arranged at two ends of the linear slide rail, a first slide block is arranged on the linear slide rail, the arc-shaped slide rail is arranged on the first slide block, a second sliding block is slidably connected with the arc-shaped sliding rail, the second sliding block is connected with the handle, a lower end of the handle is provided with the cutting knife, the cutting knife is provided with a cutting part used for cutting into rubber tree barks, the circle center of the motion trail of the second sliding block is located in the middle of the cutting part, a linear sliding rail is provided with a plurality of tooth grooves, and the first sliding block is provided with a non-return tooth block matched with the tooth grooves. According to the rubber tree bark cutting device for the tensile and shear strength test, more labor is saved when rubber tree barks are cut.

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...

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 in the direction of the trunk, the cutting knife is in full contact with the bark section, and the cutting knife is moving in translation, the pressure of the cutting knife on the bark is dispersed, and it is very laborious for the cutting knife to cut the bark
