Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery production, in particular to a threading reed for simply identifying specifications of stitched fabrics. Background Art
[0002] Currently, the typical production process for stitchbonded fabrics involves laying down different fiber gauges of glass fiber (or other fiber products such as carbon fiber or aramid) at the desired angles. After laying down single or multiple layers at varying angles, the yarns are secured in place with elastic stitching thread in coils to create a stable fabric structure. The resulting stitchbonded fabric can be single-layer or multi-layer, and thus unidirectional or multi-directional. Typical stitchbonded fabric orientations are 0°, ±45°, or 90°. Typical equipment used is a multiaxial or biaxial warp knitting machine.
[0003] Due to these weaving characteristics, stitchbonded fabrics are often differentiated by weight, ply angles, and other factors. This results in a wide variety of specifications and varying structures. This makes it difficult to distinguish and identify stitchbonded fabrics based on appearance when product information is missing. Furthermore, stitchbonded fabrics are often cut before subsequent use, making it even more difficult to identify specifications. Fabrics with unidentifiable specifications are then scrapped or discarded, resulting in significant waste and increasing the risk of misuse.
[0004] In addition, due to the excellent static mechanical properties of glass fiber composites, they are widely used in the wind power, shipbuilding, automotive and other manufacturing fields. Their excellent mechanical properties are due to the alignment of the fiber bundles. However, in actual use or experimental testing, due to the transparency of the laminate (a combination of glass fiber fabric and resin), it is difficult to capture its optimal performance. Utility Model Content
[0005] The technical problem to be solved by the utility model is to provide a threading reed for simply identifying the specifications of stitch-bonded fabrics.
[0006] In order to solve the above technical problems, the technical solution of the utility model is:
[0007] A yarn drawing reed for simply identifying the specifications of a stitched fabric comprises a weft-laying yarn drawing reed, a color yarn drawing reed and a yarn-dividing guide rod, wherein the weft-laying yarn drawing reed, the color yarn drawing reed and the yarn-dividing guide rod are arranged in parallel, and the two ends of the weft-laying yarn drawing reed, the color yarn drawing reed and the yarn-dividing guide rod are respectively fixedly connected to a bracket, and the yarn-dividing guide rod is located between the weft-laying yarn drawing reed and the color yarn drawing reed.
[0008] Preferably, the weft insertion reed for simply identifying the specifications of stitchbonded fabrics is a plate-shaped structure with first holes for passing glass fibers provided in parallel in the middle.
[0009] Preferably, the yarn threading reed for simply identifying the specifications of stitchbonded fabrics is a plate-like structure with a second eyelet provided in parallel in the middle for passing the colored yarn.
[0010] Preferably, the above-mentioned threading reed for simply identifying the specifications of stitchbonded fabrics has a plate surface width of the weft threading reed that is greater than the plate surface width of the colored yarn threading reed.

[0012] Beneficial effects:

[0015] 5-Second hole 6-Bracket DETAILED DESCRIPTION
[0016] The threading reed for simply identifying the specifications of stitch-bonded fabrics according to the present invention will be described in detail below with reference to the embodiments and the accompanying drawings.
[0017] Example 1
[0018] like Figure 1 As shown, the yarn threading reed for simply identifying the specifications of stitched fabrics includes a weft laying yarn threading reed 1, a color yarn threading reed 2 and a yarn dividing guide rod 3. The weft laying yarn threading reed is a plate-like structure, and a first hole 4 for passing the glass fiber is provided in parallel in the middle. The color yarn threading reed is a plate-like structure, and a second hole 5 for passing the color yarn is provided in parallel in the middle. The plate surface width of the weft laying yarn threading reed is greater than the plate surface width of the color yarn threading reed. The yarn dividing guide rod is a cylindrical structure. The weft laying yarn threading reed, the color yarn threading reed and the yarn dividing guide rod are arranged in parallel. The two ends of the weft laying yarn threading reed, the color yarn threading reed and the yarn dividing guide rod are respectively fixedly connected to the bracket 6, and the yarn dividing guide rod is located between the weft laying yarn threading reed and the color yarn threading reed.
[0019] The steps for applying the above-mentioned threading reed for simple identification of stitchbonded fabric specifications are as follows:
[0020] (1) When laying the fibers, colored stitching threads (hereinafter referred to as colored yarns) are laid together with the fibers. Under the action of the yarn guide rod, the colored yarns can be laid on the upper and lower surfaces of the fabric. Different grades of fiber modulus can be distinguished by using different colored yarns, and the number of colored yarns can be increased or decreased according to the density of the fiber lay. Specifically, the weft laying method of warp knitted fabrics is to use a weft laying reed (also known as a weft laying reed) to pass the fiber bundle through the first eyelet, and under the movement of the transmission mechanism, the fiber bundle is hung on the chain yarn hanging needles on both sides of the warp knitting machine to form a fiber lay. When laying the fibers, the weft laying principle of the warp knitting machine is used to simultaneously introduce the colored yarns into the fiber lay. The specific method is to use the additional colored yarn threading reed and the yarn guide rod. When laying the fibers, colored stitching threads (hereinafter referred to as colored yarns) are laid together with the fibers. Under the action of the yarn guide rod, the colored yarns can be laid on the upper and lower surfaces of the fabric. It is also suitable for warp knitted fabrics with different angles (0-90°). The density and spacing of colored yarns can be increased or decreased according to the identification requirements. Different grades of fiber modulus can be distinguished by using different colored yarns, and the number of colored yarns can be increased or decreased according to the fiber layer density.
[0021] (2) After being sewn by the sewing line, a sewn fabric with colored yarn marks in the upper and lower surface layer fibers is formed.
[0022] (3) By identifying the colored yarn, the specifications of the fabric and the modulus grade of the fabric can be determined.
[0023] After applying the aforementioned threading reed, stitchbonded fabrics clearly display the orientation of the fiber bundles, as the colored yarns are laid parallel to the fiber bundles, making identification simple and reliable. During use or testing, this allows for easier placement and alignment, more intuitively viewing the axial angle between the fiber bundles and the mold, and better leveraging the fiber's axial strength, resulting in higher mechanical performance. Furthermore, because stitchbonded fabrics are laid continuously, the colored yarn identification is maintained even when the fabric is cut into smaller pieces, allowing for quick and easy identification of fabric specifications.
[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, which are all considered to be within the scope of protection of the present invention.
