Problems solved by technology

Due to the use of a two-piece structure in the preparation process of the three-dimensional mask, there is a problem that the connection between the left side and the right side is easy to crack due to the pulling of the ear straps during use; at the same time, it is still necessary to weld the lanyard (ear strap) , there is a problem of low processing efficiency

Embodiment 1

[0048] The preparation technology of three-dimensional mask comprises the following steps:

[0049] Step 1. The roll of hanging ear material is unrolled and cut into two ear cloths 5 along the center line, and the two ear cloths 5 are transported to the pressing place at the same time;

[0050] Step 2, the rolled outer layer material 6 is transported to the pressing place after being unrolled;

[0051] Step 3. The rolled inner layer material 8 and middle layer material 7 are respectively uncoiled and transported to the compounding place, where the inner layer material 8 is compounded on top of the middle layer material 7 to obtain a pre-composite material, and the pre-composite material is sent to the lamination place delivery;

[0052] Step 4, heat-press the two earbuds 5 on both sides of the outer layer material 6 at the pressing place, and heat-press the compounded inner layer material 8 and middle layer material 7 on the top of the outer layer material 6 at the same time to...

Embodiment 2

[0060] The preparation technology of three-dimensional mask comprises the following steps:

[0061] Step 1. The roll of hanging ear material is uncoiled and transported to the dividing machine. The hanging ear material is cut into two ear cloths 5 along the center line by the dividing machine, and the two ear cloths 5 are simultaneously transported to the pressing machine;

[0062] Step 2, the coiled outer layer material 6 is uncoiled and transported to the pressing machine;

[0063] Step 3. The coiled inner layer material 8 and middle layer material 7 are respectively uncoiled and transported to the composite roller, and the composite roller composites the inner layer material 8 above the middle layer material 7 to obtain a pre-composite material, and the pre-composite material is sent to the pressing machine delivery;

[0064] Step 4, the pressing machine heat-presses two earbuds 5 on both sides of the outer layer material 6, and heat-presses the composited inner layer mate...

Abstract

The invention discloses a preparation process of a three-dimensional mask and belongs to the technical field of masks, the preparation process comprises the following steps: firstly slitting a hangermaterial into two pieces of lug cloth, compounding an inner layer material and a middle layer material into a pre-composite material, then laminating an outer layer material, the pre-composite material and the two pieces of lug cloth to obtain a composite material, laminating the lug cloth on two sides of the outer layer material, and carrying out edge sealing, folding and splayed sealing on the obtained composite material to obtain the three-dimensional mask. The manufacturing process is different from the prior art that all layers of the face are cut firstly and then the lug cloth is welded.According to the preparation process, only one-time final cutting is needed and the ear cloth does not need to be subjected to dispensing welding, so that the production efficiency is greatly improved, the production cost is saved, and the obtained three-dimensional mask is of a three-dimensional structure and is comfortable to wear; due to edge sealing and splayed sealing of the ear cloth, the product integrity is good, and the problems of cracking or ear belt breaking are not likely to occur in the using process.

Description

technical field [0001] The invention relates to the technical field of mask production, in particular to a preparation process of a three-dimensional mask. Background technique [0002] Over the past half century, with the acceleration of my country's industrialization process and the intensification of various pollutions, the living environment has continued to deteriorate. In recent years, many cities in my country have experienced a certain degree of smog weather. The smog weather is caused by intensive human activities. Fine particulate matter (PM2.5), the concentration of which will continue to accumulate, caused when the atmospheric circulation capacity is exceeded. PM2.5 is medically called inhalable particulate matter. It is a pollutant with a particle diameter of less than or equal to 2.5 microns in the atmosphere. The smaller the particle size, the deeper it enters the respiratory tract, and its deposition in the respiratory tract will seriously affect human health....
