Description
Technical Field
The utility model belongs to the technical field of spinning machine, more specifically relate to a yarn volume adjustable single needle bed send yarn device, tricot machine.
Background
In normal operation of a warp knitting machine, warp yarns are unwound from a warp beam and fed to a knitting system for knitting by a knitting machine member at a given feed rate, which is called warp feeding. The mechanism that accomplishes this is called the let-off mechanism. Let-off mechanisms are divided into two major categories, passive let-off and active let-off. All creel feeds are passive systems, the tension of each yarn being controlled by the weight of the yarn tensioner. The mechanism for driving the warp beam to rotate by the main shaft of the warp knitting machine through a transmission device to feed warp is called as an active warp feeding mechanism. The main knitting parts of the warp knitting machine are knitting needles, guide needles, sinkers and press plates. The guide bar is a device which is provided with a yarn guide needle and guides and drives yarns to do yarn laying movement. The warp yarns pass through the eyelets of the guide needles, are fed with the guide bar to be wound around the needles, and are knitted into a fabric by the cooperative movement of knitting members such as knitting needles and sinkers.
The fly-knitted integrated vamp is a single-layer or multi-layer vamp which is integrally knitted and formed by a brand-new knitting process by utilizing a 3D (three-dimensional) integrated forming technology. The integrated vamp flying-weaving machine has the advantages that the integrated vamp flying-weaving machine is directly molded with the sole in later-stage production, various processes of the traditional vamp are greatly reduced, the vamp sewing worker can be saved, the vamp production efficiency is greatly improved, the production mode of the traditional sports shoes is overturned, and therefore the integrated vamp flying-weaving production technology is developed at a high speed in recent years. When the single needle bar warp knitting machine is used for carrying out mass production of vamps, the working width of the warp knitting machine can be used for arranging a plurality of vamps side by side, and the rest parts of the whole cloth except shoe face materials are non-vamp area leftover materials for connection. When finishing in later stage, only need to cut it along the profile of a slice of integral vamp, abandon or recycle unnecessary non-vamp regional leftover bits.
More information about the above-described solutions can also be found in the following documents. The Chinese patent application CN106048877A discloses a warp knitting machine for producing single-layer structure three-dimensional jacquard vamp fabrics and a production method thereof. Designing a vamp template according to the design requirements of all parameters; designing through CAD software, converting the CAD software into a machine file which can be read by a warp knitting machine, and inputting the machine file into the warp knitting machine; the jacquard comb is arranged in the middle of the machine, and the ground combs are arranged on two sides of the jacquard comb; knitting is carried out after the guide bar is threaded, a jacquard comb is used for knitting a three-needle looping structure, and a ground comb is used for knitting a needle weft insertion structure or a chaining structure; according to different requirements of vamp fabrics, the jacquard comb carries out the same-direction or reverse lapping, and the corresponding ground comb participates in the knitting; finally forming the single-layer structure three-dimensional jacquard forming vamp after finishing. The jacquard effect of the fabric produced by the utility model is clear, and the pattern has strong stereoscopic impression; the single-layer jacquard vamp adopts the nylon-polyester raw material to realize the double-color effect, and can be compounded with the plain mesh cloth with a three-layer structure or a single-layer structure at the later stage, so that the color effect is more abundant; the composite fabric has excellent stiffness and wear resistance, and is good in stability after being compounded with other fabrics.
The Chinese invention patent CN109402857B discloses a manufacturing process of a vamp mesh cloth, which comprises the steps of weaving preparation, guide bar configuration, weaving on a machine, dyeing and finishing and shaping and the like, wherein when the non-vamp area is woven, each mesh on a mesh base layer is transversely penetrated with a jacquard embroidery yarn to form a thin structure, when the vamp area is woven, each mesh on the mesh base layer is transversely penetrated with the jacquard embroidery yarn to form a thick structure or each mesh on the mesh base layer is not transversely penetrated with the jacquard embroidery yarn to form a hollow structure, the boundary between the thin structure and the thick structure or the hollow structure is utilized to form the outline shape of the unfolded vamp, the jacquard embroidery yarn is woven by the jacquard comb, the tissue type of the fabric does not need to be changed, the process is relatively simple, and compared with the traditional technical scheme of obtaining the vamp by adopting a mode of cutting and then sewing, the cost is relatively low.
However, in the prior warp knitting and fly knitting integrated vamp production process, as the jacquard and bottom comb are warp fed by a warp beam pan head, the warp feeding amount is constant when the gray cloth and the leftover materials of the integrated vamp are knitted, and therefore, the loss of the leftover materials in the whole width cloth fabric of a lower machine is large. Some cloth can cause the stability of the whole width of cloth to be reduced due to improper operation by adjusting the let-off tension, and in a word, technical breakthroughs are urgently needed to be made on the basis of ensuring the width stability of the lower machine and saving the yarn consumption.
Disclosure of Invention
In view of the above-described problems in the background art, it is desirable to provide a single-bed yarn feeder and a warp knitting machine with an adjustable yarn feeding amount. The single-needle bed yarn feeding device with the adjustable yarn feeding amount and the warp knitting machine can adjust the yarn feeding amount of different areas on the breadth according to different requirements, and the single-needle bed yarn feeding device with the adjustable yarn feeding amount and the warp knitting machine thereof can enable the weft width stability of a lower machine at the later stage to be strong, the yield and the quality of vamp finished products are not affected, the leftover loss of non-vamp areas of yarns is greatly reduced, and the purpose of reducing the production cost of the vamps is achieved.
