Abstract

The invention relates to performance detection equipment, in particular to mask nose bridge strip performance detection equipment. The invention provides performance detection equipment for a mask nose bridge strip to be written. Mask nose bridge strip performance detection equipment comprises a supporting frame, supporting rods, first rollers, a first conveying belt, a mask mold and the like, the supporting rods are symmetrically arranged on the left side and the right side of the top of the supporting frame front and back, the first rollers are rotationally connected between the upper portions of the two supporting rods on the same side in the longitudinal direction, and the first conveying belt is connected between the first rollers in a wound mode. And mask molds are uniformly arranged on the first conveying belt at intervals. The nose bridge strip is bent downwards through the nose bridge strip pressing frame, then unqualified masks and qualified masks are conveyed through the second conveying belt and the first conveying belt respectively, detection of the bending resistance of the nose bridge strips of the masks is achieved, operation is easy and convenient, and practicability is high.

Description

technical field [0001] The invention relates to a performance testing device, in particular to a performance testing device for the nose bridge strip of a mask. Background technique [0002] Masks are daily anti-infection protective equipment. In order to make masks fit more firmly with people's faces and achieve basic protection, manufacturers will weld nose bridge strips at the nose bridge when producing masks, and some unqualified nose bridge strips are bent. Afterwards, it will be restored like a memory metal, and the bending resistance is poor, resulting in a poor fit between the mask and the face, resulting in poor protection. In order to improve the protection of the mask, it is necessary to detect and pick out this batch of unqualified masks for rework . [0003] The patent application CN202614954U, the date of publication is 2012121, discloses a mask nose bridge detector, including an infrared sensor and an alarm, and an adjustment rod is symmetrically arranged on ...
