Description

Technical Field

[0001] The utility model belongs to the technical field of warp knitted glass fiber fabrics, in particular to a warp knitted glass fiber fabric bound by a double-bar butt-seam braiding structure. Background Art

[0002] In recent years, with the rise of environmentally friendly new energy, wind power generation has begun to be vigorously developed. Wind energy is one of the most commercially promising and dynamic renewable energy sources. The development prospects of the wind new energy power generation industry are very broad. It is expected to maintain rapid development for a long time in the future. At the same time, profitability will also steadily increase as the technology gradually matures.

[0003] Fiberglass fabrics used in wind power plants must be pre-cut to specific sizes and placed in molds. Cutting the fabric pieces into the kit disrupts the stitched fabric structure, causing the pieces to easily unravel at break points. This can compromise the fabric's performance and even affect the appearance and static mechanical properties of the finished fiberglass reinforced plastic. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the sewing of glass fiber fabrics is unstable due to the process organization, thereby affecting the cutting quality, and provides a warp-knitted glass fiber fabric with a double-bar seam-knitting structure.

[0005] In order to solve the above problems, the technical solution of the present utility model is:

[0006] The warp knitted glass fiber fabric bound by the double-bar butt-seam weaving structure is bound by using the butt-seam weaving of the comb bars GB1 and GB2 on the warp knitted glass fiber fabric;

[0007] The comb bar GB1 is a warp plain + chain braided structure with a structure of 01 / 10 / 21 / 12;

[0008] The comb bar GB2 is a warp plain + chain braided structure with a structure of 01 / 10 / 21 / 12.

[0009] The yarn laying motion diagram of combing bar GB1 and combing bar GB2 is as follows: Figure 2 As shown, the structural diagram of the warp knitted glass fiber fabric bound by the double-bar seam braiding structure is as shown Figure 1 shown.

[0010] Furthermore, the yarns used by the combing bars GB1 and GB2 are polyester yarns.

[0011] Furthermore, the elastic modulus of the polyester yarn is 22 to 141 cN / dtex.

[0012] Furthermore, the linear density of the polyester yarn is 83 dtex.

[0013] Furthermore, on the warp-knitted glass fiber fabric, perpendicular to the warp direction, the combing bars GB1 and GB2 are used for butt-weaving to bundle the warp-knitted glass fiber fabric.

[0014] The double-bar butt-seam braided structure of the present invention is used to bundle and weave warp-knitted glass fiber fabrics using an E7 warp knitting machine. The bar GB1 uses a pattern plate E7, 16M (01 / 10 / 21 / 12). The pattern plate of the bar GB2 is modified on the basis of the pattern plate of the bar GB1:

[0015] There are 5 positioning holes on the faceplate E7 and 16M (01 / 10 / 21 / 12), of which the lines connecting the four first positioning holes are perpendicular to each other, and the remaining second positioning hole is located in the middle of two adjacent first positioning holes. An arc-shaped slide groove is opened in the middle of the four first positioning holes with lines connecting them perpendicular to each other, and one of the arc-shaped slide grooves covers the position of the original second positioning hole.

[0016] The comb bar GB2 adjusts the position of the push rod between the comb bar and the disc, so that the comb bar GB1 and the comb bar GB2 move horizontally by the distance of one needle. Figure 5 The comb bars GB1 and GB2 are placed in the equipment with discs, and the disc used by GB2 is positioned in the arc-shaped slide to facilitate adjustment of the pattern travel and prevent the comb bars GB1 and GB2 from hitting the needles.

[0017] The beneficial effects of the utility model are as follows:

[0018] (1) The double-comb seam-woven warp-knitted glass fiber fabric of the present invention is a warp-knitted glass fiber fabric that is sewed and bound using a special structure, which can greatly reduce the problem of fabric dragging caused by the damage to the sew-woven fabric structure during the cutting process.

[0019] (2) The utility model uses polyester yarn to bundle the warp-knitted glass fiber fabric, which will not cause poor interface bonding between the glass fiber and the resin, thereby reducing the static mechanical properties of the glass fiber reinforced plastic.

[0027] The present invention will be described in detail below in conjunction with the embodiments.

[0028] Example 1

[0029] like Figure 1-5 As shown, the warp knitted glass fiber fabric bundled with the double-bar butt-seam weaving structure is bundled on the warp knitted glass fiber fabric 6 by using the butt-seam weaving of the bars GB1 and GB2 perpendicular to the warp direction;

[0030] The comb bar GB1 is a warp plain + chain braided structure with a structure of 01 / 10 / 21 / 12;

[0031] The comb bar GB2 is a warp plain + chain braided structure with a structure of 01 / 10 / 21 / 12.

[0032] The yarn laying motion diagram of combing bar GB1 and combing bar GB2 is as follows: Figure 2 As shown, the structural diagram of the warp knitted glass fiber fabric 6 bound by the double-bar seam braiding structure is as shown in FIG. Figure 1 shown.

[0033] It can be understood that the yarns used by the combing bars GB1 and GB2 are polyester yarns 7 .

[0034] It can be understood that the elastic modulus of the polyester yarn 7 is 22 to 141 cN / dtex.

[0035] It can be understood that the linear density of the polyester yarn 7 is 83 dtex.

[0036] The double-bar butt-seam braided structure of the utility model is used to bundle and weave the warp-knitted glass fiber fabric 6 using an E7 warp knitting machine. The bar GB1 adopts a disc 1: E7, 16M (01 / 10 / 21 / 12). The disc of the bar GB2 is modified on the basis of the disc 1 of the bar GB1:

[0037] Five positioning holes are opened on the faceplate 1: E7, 16M (01 / 10 / 21 / 12), among which four first positioning holes 201 are connected perpendicularly to each other, and the remaining second positioning hole 202 is located in the middle of two adjacent first positioning holes 201. An arc-shaped slide groove 3 is opened in the middle of the four first positioning holes 201 whose lines are connected perpendicularly to each other, and one of the arc-shaped slide grooves 3 covers the position of the original second positioning hole 202.

[0038] The comb bar GB2 adjusts the position of the push rod 4 between the comb bar 5 and the disc 1, so that the comb bar GB1 and the comb bar GB2 move horizontally by the distance of one needle. Figure 5 The comb bars GB1 and GB2 use discs 1 to be placed in the equipment disc positioning rod, wherein the disc 1 used by GB2 is positioned in the arc-shaped slide 3 to facilitate adjustment of the pattern travel stroke and prevent the comb bars GB1 and GB2 from hitting the needles.

[0039] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
