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 protectio

Embodiment 1

[0048] like figure 1 Shown is a schematic diagram of the overall structure of a filterability detection process for the production of epidemic prevention masks based on melt blown cloth according to the present invention.

[0049] A filterability detection process based on melt-blown cloth to produce anti-epidemic masks, including the following steps:

[0050] S1. Material selection and installation: the staff will place the selected materials that need to be tested on each test base one by one;

[0051] S2. Clamping limit: carry out stable clamping limit on the selected materials placed on each test base in step S1, and open the small hydraulic cylinder 6 by controlling. At this time, under the working action of the small hydraulic cylinders 6 on both sides, combined The corresponding hydraulic rod 7 can push the mounting plate 8 to move downward on the cascade impactor 5 stably, and then under the action of the continuous movement of the mounting plate 8, it can drive each ...

Embodiment 2

[0059] like Figure 2-Figure 13 As shown, it is a schematic diagram of the overall structure of a filterability detection device based on melt-blown cloth to produce anti-epidemic masks according to the present invention;

[0060]A filter detection device for producing anti-epidemic masks based on melt-blown cloth, including a fixed base 1, on which a control device 2 and a cleaning component 13 are installed, and the cleaning component 13 can ensure the subsequent cleaning of the test base 3 and the fixed cylinder 9 stability and convenience, the top surface of the fixed base 1 is welded and fixed with a test base 3, the inner bolt of the test base 3 is equipped with a first differential pressure sensor 4, and the fixed base 1 is equipped with an aerosol generator 14, an aerosol generator 14 is installed with a cascade striker 5, the top of the cascade striker 5 is welded and fixed with a small hydraulic cylinder 6, the output end of the small hydraulic cylinder 6 is connecte...

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...
