Filterability detection process for epidemic prevention mask produced based on melt-blown cloth

Abstract

The invention belongs to the field of epidemic prevention mask production, and particularly relates to a filterability detection process for epidemic prevention mask production based on melt-blown cloth, which comprises the following steps: S1, material selection and installation: a worker places selected materials needing to be detected on each test base one by one; S2, clamping and limiting: stable clamping and limiting are performed on the selected materials placed on each test base in the step S1, small hydraulic cylinders are controlled to be started, at the moment, under the working action of the small hydraulic cylinders on the two sides, a mounting plate can be pushed to stably move downwards on a cascade impactor in combination with corresponding hydraulic rods, the small hydraulic cylinder and the hydraulic rods can drive all fixing barrels at the bottom of a mounting plate to move downwards at the same time, stable cooperation work can be conducted with corresponding test bases. Convenient and stable comparison detection work is conducted on multiple selected materials at the same time, deviation of the detection result of the selected materials can be effectively prevented, andthe use stability and accuracy of the device are improved.

Description

technical field [0001] The invention relates to the field of production of anti-epidemic masks, in particular to a filterability detection process for producing anti-epidemic masks based on melt-blown cloth. Background technique [0002] Existing, at present, for the preparation process method of a high-filtering non-woven mask of polymer material disclosed in the patent number CN202010594295.5, and the non-woven mask body and a pair of ear hook parts are integrally formed, and The non-woven mask body consists of a four-layer structure of biodegradable non-woven fabric, purified non-woven cotton, double-layer melt-blown fabric and polypropylene melt-blown microfiber non-woven fabric in order from far away from the mouth and nose to close to the mouth and nose. , and a 325-mesh white nano-microporous adsorbent layer with the function of absorbing harmful gases is added between the double-layer melt-blown cloth. After the mask is formed and before packaging, the mask is folded...

AI Technical Summary

Problems solved by technology

[0004] At present, the conventional detection method of filterability of meltblown cloth in the market is that it is impossible to carry out automatic and stable clamping and limiting work on the material selection of meltblown cloth during the actual application process. The cloth selection material is easily shifted or shifted, which cannot guarantee the stability and safety of the subsequent detection work of the melt blown cloth material selection; the conventional melt blown cloth filterability detection device cannot select the melt blown cloth material Carry out convenient and stable sealing and protection work, and thus cannot guarantee the accuracy of the follow-up detection results of the melt-blown cloth material selection, and the practicability is poor; after the conventional melt-blown cloth filterability detection device is used, the device cannot check the upper and lower sides. The test channels are cleaned at the same time. The staff need to clean the test channels on the upper and lower sides one by one. The work efficiency is low. Therefore, it is necessary to provide a filterability detection process based on the production of anti-epidemic masks based on melt-blown cloth to meet the needs of users.
