Description
Technical Field
The utility model relates to a straw bundling net warp knitting machine, more specifically say, relate to a straw bundling net warp knitting mechanism and warp knitting machine and the straw bundling net of preparation thereof.
Background
The straw-binding net is a large-mesh (hole) fabric for binding straw, pasture and other plants, and is named for its use function. The straw-tying net is a warp-knitted fabric, also called a knotless fishing net, and is generally produced by knitting with a warp knitting machine. The grass binding net is structurally characterized in that a plurality of groups of parallel and same warp knitting chains are arranged in the longitudinal direction, weft insertion is arranged in the transverse direction, and the longitudinal knitting chains are connected through the weft insertion to form a mesh fabric. The structure of the grass binding net is characterized in that the braided wires are thick (the machine number is high), the meshes are large, the concrete embodiment is that the distance between every two transverse braided chains and the distance between every two longitudinal braided chains (meshes) are large, and the common distance is one inch.
As shown in fig. 1, the specific structure of the conventional grass-baling net includes a plurality of warp chains 101 parallel along the warp direction, each warp chain 101 is formed by connecting a plurality of groups of warp-knitted loop links 102 in series, and weft insertion 103 is arranged between two adjacent warp chains 101 along the weft direction, thereby forming a net structure. Due to the warp knitting structure, loop structures are formed between the coil links 102 in each warp chain 101 and between the weft insertion 103 and the coil links 102, and the coil links 102 are formed by looping warp fibers 104.
Fig. 2 shows a latch needle or composite needle single-needle bed warp knitting machine currently used for producing the straw baling net in fig. 1, and the core structure of the warp knitting machine is a looping device, which specifically includes a knitting needle 1 (latch needle or composite needle, and reference numeral 1 in fig. 2 is a composite needle, including a grooved needle 1-1 and a needle core 1-2), a knockover plate 2 (or knockover needle), a sinker 3, and a guide bar 4 (or guide needle), and the knitting needle 1, the knockover plate 2, the sinker 3, and the guide bar 4 are also called looping machine elements. The warp knitting machine for knitting the grass baling net at present consists of two guide bars, and the guide bar 4 consists of a looping guide bar 4-1 and a weft insertion guide bar 4-2. The guide bar 4 swings along the front-back direction (shown in figure 2) of the whole machine and reciprocates in a straight traversing way along the left-right direction of the whole machine, the knitting line on the looping guide bar 4-1 is padded with the knitting needle 1 by the swinging and traversing of the looping guide bar, and then looping is carried out under the action of the knocking-over plate 2 to form a knitting chain; for the weft insertion guide bar 4-2, the knitting line on the weft insertion guide bar does not need to be looped, only needs to transversely move on the needle back of the knitting machine 1, does not need to transversely move in front of the needle on the knitting needle 1, namely only needs to transversely move along the left and right (transverse) reciprocating straight lines of the knitting machine 1, and then the knitting line can be formed between two adjacent parallel knitting chains. The working principle of the existing grass bundling net warp knitting machine can also be seen in 'a grass bundling net warp knitting machine' disclosed in Chinese patent No. ZL 201921275605.6.
According to the binding function of the grass net, a certain strength is required along the warp direction. In actual use, the conventional grass binding net mainly bears external force applied after straw, pasture and the like are bound by the warp-direction chains. When the warp yarn applied with external force is not durable and is easy to break, the mesh fabric may be scattered, the grass-tying work cannot be smoothly carried out, and in order to enhance the bearing capacity of the grass-tying net, the bearing capacity of the warp-direction chains should be increased as much as possible. Therefore, chinese patent No. ZL202020057839.X proposes a technical scheme of a warp-lined warp-direction chain knitting structure for a mesh grid and a grass-binding net using the warp-lined warp-direction chain knitting structure, wherein a warp-direction chain 101 is formed by compounding two parts of a looping knitting chain L and a lining warp 105 which is straightly lined in the looping knitting chain L, and the looping knitting chain L is formed by connecting coil chain links formed by warp fibers 104 in series. The straight warp padding 105 and the looped knitted chain L bear the bearing load of the warp-wise chain 101, the warp padding 105 has no bending and strength weakening problems, the strength of the knitted chain is improved, and the overall strength of the grass-baling net with the warp-wise chain structure of the warp padding is improved.
At present, no warp knitting machine for synchronously lining warp padding which commonly bears warp direction load in the warp knitting process exists, so that a novel straw bundling net warp knitting machine which is high in speed and capable of knitting three strands is urgently needed.
