The technical scheme protected by the utility model is specifically described below with reference to the accompanying drawings.
As shown in fig. 1, a metal gauze comprises a plurality of warps 1 and wefts 2 which are integrally structured, wherein adjacent warps 1 and adjacent wefts 2 are respectively arranged in parallel, the warps 1 and the wefts 2 are arranged in a staggered manner to form a printing area 3 and a non-printing area 4, wherein the printing area 3 is used for metal paste printing and forming, the non-printing area 4 plays a tensioning role, the strength of the whole metal gauze functional area is increased, in the printing area, the section thickness and/or the section width of two adjacent warps 1 are different, and the section thickness and/or the section width of two adjacent wefts 2 are different. Through reducing the cross-sectional dimension of warp 1 or weft 2 for metal thick liquids can be better when passing through printing region 3, more be favorable to the shaping of metal thick liquids, improved the shaping quality of metal wire.
Example 1
As shown in fig. 2, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The thickness of the cross section of two adjacent warp threads 1 is gradually reduced and then gradually increased, and the width of the cross section is equal. And the section thickness and/or section width of two adjacent wefts 2 may be equal or different. In example 1, the forming quality of the metal paste becomes better as the thickness of the cross section becomes smaller, but the strength of the warp yarn 1 becomes lower, so that the thickness of the warp yarn 1 needs to be increased gradually after a certain thickness value is reached, so as to ensure that the printing area of the whole metal gauze has enough strength.
Further, the minimum cross-sectional thickness of the warp yarn 1 in the non-printing area 4 is larger than the minimum cross-sectional thickness of the warp yarn 1 in the printing area 3, and the minimum cross-sectional thickness of the weft yarn 2 in the non-printing area 4 is larger than the minimum cross-sectional thickness of the weft yarn 2 in the printing area 3. The cross-sectional size of the non-printing area 4 is larger than that of the printing area 3, so that the strength of the non-printing area 4 is larger than that of the printing area 3, and the strength of the whole metal gauze is ensured by enlarging the cross-sectional size of the non-printing area 4 because the non-printing area 4 does not need to be permeated by metal paste.
Example 2
As shown in fig. 3, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The thickness of the sections of two adjacent warp threads 1 are arranged at intervals, and the widths of the sections are equal. And the section thickness and/or section width of two adjacent wefts 2 may be equal or different. In embodiment 2, the sections of two adjacent warp threads 1 are arranged at intervals, the area with smaller section thickness has good printing effect, and the area with larger section thickness ensures the strength, so that the stability of the strength is better when the two warp threads are arranged at intervals.
Example 3
As shown in fig. 4, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The thickness of the cross section of every two adjacent warps 1 is reduced by N and then increased by M, wherein N is more than or equal to 1 and less than or equal to 20, and M is more than or equal to 1 and less than or equal to 20. And the section thickness and/or section width of two adjacent wefts 2 may be equal or different. In embodiment 3, the printing effect is good in the area with smaller section thickness, and the strength is better in the area with larger section thickness, and by irregularly increasing or decreasing the section thickness, the printing effect of the metal paste can be ensured, and the strength can be ensured.
Example 4
As shown in fig. 5, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The cross-sectional widths of two adjacent warp threads 1 are gradually reduced and then gradually increased, and the cross-sectional thicknesses are equal. And the section thickness and/or section width of two adjacent wefts 2 may be equal or different. In example 4, as the cross-sectional width of the warp yarn 1 gradually decreases, the permeability of the metal paste gradually increases, and the printing effect can be improved, but in order to ensure the strength of the metal gauze, the cross-section of the warp yarn needs to be increased when it decreases to a certain value, thereby ensuring the strength of the warp yarn.
Example 5
As shown in fig. 6, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The cross section widths of two adjacent warp threads 1 are arranged at intervals, and the cross section thicknesses are equal. And the section thickness and/or section width of two adjacent wefts 2 may be equal or different. In embodiment 5, the cross-sectional widths of two adjacent warp yarns 1 are arranged at intervals, the area with smaller cross-sectional width has good printing effect, and the area with larger cross-sectional width ensures the strength, so that the strength stability is better when the warp yarns are arranged at intervals.
Example 6
As shown in fig. 7, which is a schematic view of section A-A of fig. 1, this embodiment is a single-layer metal gauze, and the cross-sectional shape is a cross-sectional view of warp yarn 1. The section thickness and the section width of the two adjacent warp yarns 1 are arranged at intervals, and the section thickness and/or the section width of the two adjacent weft yarns 2 can be equal or unequal at the moment. In embodiment 6, the warp threads with small section thickness and section width are arranged at intervals, the permeability of the metal paste is good, and the warp threads with large section thickness and section width are good in strength, so that the printing effect can be enhanced, and the metal gauze can be guaranteed to have certain strength.
Example 7

The two faces defining the printing area are a first plane 5 and a second plane 6, the warp threads of the first plane 5 and the second plane 6 in this embodiment being provided as concave-convex surfaces. And its thickness is the rule that the interval becomes little, and the scraper face of first plane 5 sets up to the concave-convex surface, more is favorable to scraping into metal thick liquids, and the printing face of second plane 6 sets up to the concave-convex surface, more is favorable to metal thick liquids shaping.
