The invention discloses a nose bridge strip fatigue strength detection device and a method thereof. The nose bridge strip fatigue strength detection device comprises a machine table, a first fixing mechanism, a second fixing mechanism, a driving mechanism and a counting mechanism, wherein the first fixing mechanism is arranged on the machine table and provided with a long-strip-shaped containing groove used for containing part of the nose bridge strip. Two sides of one port of the containing groove are respectively provided with a fillet structure for bending the nose bridge strip; the secondfixing mechanism is provided with a locking groove used for containing part of a nose bridge strip, the second fixing mechanism is rotatably connected to the machine table, and the driving mechanism is connected to the second fixing mechanism and used for driving the second fixing mechanism to rotate in a reciprocating mode. The counting mechanism is connected with the driving mechanism and used for calculating the number of times of reciprocating rotation of the second fixing mechanism. The nose bridge strip fatigue strength detection device can realize automatic detection of the fatigue strength of the nose bridge strip of the mask, and is high in automation degree and accurate in detection result.
Description
technical field [0001] The invention relates to the fields of textile and protection, in particular to a device and method for detecting the fatigue strength of a nose bridge strip. Background technique [0002] At present, a new type of tubular virus pneumonia is raging all over the world, and masks have become consumables. Generally, a bendable nose bridge is installed inside the mask. After wearing the mask, squeeze the nose bridge of the nose so that the upper part of the mask fits the nose and the shape of the face more effectively, effectively preventing the entry of germs. [0003] Before the production of masks, the quality inspection of the nose bridge strip is required. At present, it is difficult to quickly carry out the quality inspection of the nose bridge strip under the huge order pressure. Usually, the nose bridge strip is repeatedly bent several times by hand until the nose bridge strip breaks, and then Record the number of bends. Manual inspection is time...
