Automatic compounding technology process method for cup-shaped mask

Abstract

The invention relates to the technical field of mask manufacturing, and discloses an automatic compounding technology process method for a cup-shaped mask, which comprises the following steps: step 1, preparing materials; step 2, performing coincidence cutting; step 3, feeding; step 4, shaping a filter layer; step 5, assembling and forming; and step 6, performing quality inspection. According to the automatic compounding technology process method for the cup-shaped mask, during heating treatment and edge sealing treatment, a double-sided colloid material is added between the filtering layer and the inner and outer layers to prevent movement during heating treatment, and heat insulation strips are added between the filtering layer and the inner and outer layers to prevent the filtering layer from being damaged by high temperature and high pressure during edge sealing treatment; and the forming quality of the mask is effectively improved.

Description

technical field [0001] The invention relates to the technical field of mask production, in particular to a cup-shaped mask automatic composite technology process. Background technique [0002] At present, the composite process of the cup-shaped mask is to integrally form the main middle filter layer of the mask through equipment mold compression molding or manually form it, so that it forms the main body of the mask with the outer layer and inner layer of the mask. [0003] During the mask making process, the material of the filter layer of the mask will be damaged by heat, pressure, and pulling, resulting in a significant decline in its performance, which is reflected in the finished mask, that is, the key technical indicators such as filtration efficiency and resistance drop or fail to meet standards. [0004] The commonly used composite process of cup-shaped masks in the prior art is mainly divided into two types: [0005] One is to manually cover the filter layer outsid...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies in the prior art, the present invention provides a cup-shaped mask automatic compounding technology process, which can solve the problem of manual compounding low efficiency and automatic compounding using high pressure or hot pressing in the existing cup-shaped mask automatic compounding technology process It is easy to cause damage to the filter layer during molding, which in turn leads to the destruction of indicators such as filtration efficiency, breathing air resistance, and electrostatic decay cycle; the present invention adds double-sided Colloidal material to prevent movement during heat treatment, and add heat insulation strips between the filter layer and the inner and outer layers to prevent damage to the filter layer caused by high temperature and high pressure during edge sealing, effectively solving the existing automatic compounding of cup-shaped masks The technical process method is low efficiency of manual compounding, and it is easy to damage the filter layer when using high pressure or hot pressing during automatic compounding, which will lead to the destruction of filtration efficiency, breathing air resistance, electrostatic decay cycle and other indicators.
