Mask ventilation resistance and pressure difference tester with closed structure

Abstract

The invention discloses a mask ventilation resistance and pressure difference tester with a closed structure, and relates to the technical field of mask production. Comprising a machining table, a tester is arranged on one side of the top of the machining table, a controller is installed in the tester, a display screen electrically connected with the controller is arranged at the top of the tester, a pressing block and a base are sequentially arranged on the machining table and used in cooperation, a machining table top is arranged on the front face of the tester, and the base is arranged on the machining table top. A leveling structure is installed on the machining table top, a moving structure is installed on the front face of the tester, and an overturning structure is arranged on the moving structure. According to the invention, the mask can be automatically tested, the automation degree is high, the labor burden of operators is small, the device can adapt to large-scale detection operation of factories, and the arranged leveling structure can play roles in leveling and conveying the mask at the same time, so that the mask cannot wrinkle, the test effect is further improved, and manual leveling is not needed.

Description

technical field [0001] The invention relates to the technical field of mask production, in particular to a mask ventilation resistance and pressure difference tester with a closed structure. Background technique [0002] A mask is a kind of hygiene product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper. Masks have a certain filtering effect on the air entering the lungs. Wearing masks has a very good protective effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. In the process of mask production, in order to ensure the protection of the mask, it is necessary to test the ventilation resistance and pressure difference of the mask. [0003] At present, the traditional ventilation resistance and pressure difference tester for masks has the following two problems in use. First,...

AI Technical Summary

Problems solved by technology

[0003] At present, the following two problems exist in the use of traditional masks with ventilation resistance and pressure difference testers. First, operators need to detect one by one. When the number of masks to be tested is large, the labor burden of the operators is too large, and The degree of automation is low, and it is difficult to adapt to the large-scale detection operation of the factory. Second, it is necessary to manually smooth the mask, and the smoothing effect is poor. A new type of solution
