Melt-blown fabric strength testing device for intermittent mask production

Abstract

The invention provides a melt-blown fabric strength testing device for intermittent mask production, and relates to the field of melt-blown fabric processing. The melt-blown fabric strength testing device comprises a testing table, the upper surface of the testing table is fixedly connected with a mounting plate and two inverted-U-shaped mounting frames, and the two mounting frames are symmetrically arranged relative to the mounting plate. Through mutual cooperation of the mounting plate, a movable rotating rod, an electric driving device, a mounting sleeve, an adjusting mechanism and a flapping seat, the electric driving device can drive the movable rotating rod and the mounting sleeve to rotate integrally, the flapping seat flaps cloth conveniently, and the adjusting mechanism can drivethe flapping seat to move, so that the distance between the flapping seat and the mounting sleeve can be changed; the force application size and direction of the beating seat can be adjusted, different forces can be applied from different directions, the limitation of a detection result is reduced, and the quality of melt-blown cloth can be conveniently and more accurately judged.

Description

technical field [0001] The invention relates to the technical field of melt-blown cloth processing, in particular to a device for testing the strength of melt-blown cloth fabrics for intermittent mask production. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper, etc. It has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust, and the melt-blown fabric is made of polypropylene as the main raw material for filtering Material is also the main filter material currently used in mask production. [0003] During the production process of the melt-blown cloth, due to its special spraying prope...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for testing the strength of melt-blown cloth fabrics for discontinuous mask production, which solves the problem of the strength detection device in the prior art, which has a single form and can only be applied to one position or from one direction Force, and the magnitude of the applied force is certain, which makes the test results have a relatively large limitation
