Embodiment 1

[0042] Embodiment one, is a kind of mouth mask disclosed by the present invention, with reference to figure 1 , including a mask body 1 and a pair of ear straps 2 fixed on both sides of the mask body 1 respectively.

[0043] refer to figure 1 , figure 2 , The mask body 1 includes an inner non-woven fabric layer 11, a filter layer 12 and an outer non-woven fabric layer 13 arranged in sequence. The filter layer 12 is a meltblown cloth layer. The side of the inner non-woven fabric layer 11 away from the filter layer 12 is the skin-facing surface, and the side of the outer non-woven fabric layer 13 away from the filter layer 12 is the skin-facing surface.

[0044] refer to figure 2 , image 3 , the upper edge and the lower edge of the inner non-woven fabric layer 11 are respectively formed with an upper extending edge 111 and a lower extending edge 112 . After the upper extending edge 111 and the lower extending edge 112 are turned over, they are welded together with the u...

Embodiment 2

[0049] Embodiment two, a kind of processing technology of mask, is used for producing the mask disclosed in embodiment one, with reference to Figure 1-3 , including the following steps:

[0050] S0, first carry out electret treatment to filter layer 12;

[0051] S1. Stack the inner non-woven fabric layer 11, the filter layer 12 and the outer non-woven fabric layer 13 sequentially from bottom to top to form a semi-finished product, and fold the semi-finished product in the width direction by a punching machine to form four pleats;

[0052] S2. Carry out hot pressing on both side edges of the folded semi-finished product, so that the inner non-woven fabric layer 11, the filter layer 12 and the outer non-woven fabric layer 13 are welded together;

[0053] S3. Carry out secondary hot pressing on the two ends of the earband 2 and the upper edge and the lower edge of the outer nonwoven fabric layer 13 respectively, so that the earband 2 and the outer nonwoven fabric are welded tog...

Abstract

The invention discloses a mask and a processing technology thereof, and relates to the technical field of mask processing. The mask comprises a mask body and ear bands, the mask body comprises an inner non-woven fabric layer, a filtering layer and an outer non-woven fabric layer which are arranged in sequence, one side, deviating from the filtering layer, of the inner non-woven fabric layer is a skin opposite surface, one side, deviating from the filtering layer, of the outer non-woven fabric layer is a skin back surface, the mask body is provided with a first pleated part, a second pleated part, a third pleated part and a fourth pleated part in the width direction, the mask body is bent into a structure with an omega-shaped cross section at the second pleated part and the third pleated part, the processing technology comprises the steps that the inner non-woven fabric layer, the filtering layer and the outer non-woven fabric layer are stacked into a semi-finished product, the side edges of the semi-finished product are hot-pressed, the ear bands are welded, a nose bridge strip is fixed, the upper edge and the lower edge of the mask body are hot-pressed, and a silicone sheet is bonded. The mask has good ductility and can better wrap the face of a wearer, and an excellent protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of mask processing, in particular to a mask and its processing technology. Background technique [0002] At present, the mask mainly includes two parts: a mask body and ear straps fixed on both sides of the mask body. The processing process is as follows: first process the main body of the mask, then cut the main body of the mask into a single mask body, and then turn it over to a conveyor belt perpendicular to the body forming machine through a mechanism such as a cylinder, and the conveyor belt moves the product forward through intermittent motion After conveying, the product is sent to the welding station of the hanging ear rope, and the hanging ear rope is welded on the body. [0003] Existing, notification number is that the Chinese patent of CN203677771U discloses a kind of mouth mask, and mouth mask is made of multilayer mask main body and a pair of ear hanging parts, and this multilayer mask main bo...
