Description
Technical Field
The invention belongs to the technical field of textile machinery, and particularly relates to a yarn feeding device of a double-needle-bed jacquard machine capable of saving yarns, a warp knitting machine and application.
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 double-needle bed 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 CN108914361A 'super-woven shoe material fabric' discloses a super-woven shoe material fabric which is manufactured by a yarn pressing type double jacquard warp knitting machine, two separated jacquard comb shapes form a relief yarn pressing pattern before yarn pressing, yarns are wound at the root of a coil and are pressed mutually, and the fabric is firm and firm. The back of the yarn pressing plate is provided with a chaining coil which is used for sleeving and stringing the yarns before yarn pressing, and the fabric texture is compact. Two separating jacquard combs in front of the yarn pressing plate are matched with each other in jacquard function, and the thickness and the meshes of the two separating jacquard combs are designed according to different positions, such as air holes, shoe lace holes, thin outline edges and the like, so as to facilitate cutting. Can wear various color materials, can be jacquard into abundant patterns and required trademarks, etc. The terylene material is adopted, and the terylene has high strength, consistent dry and wet states, good elasticity, good wear resistance and good light resistance, so that the formed fabric is suitable for outdoor complex environment. Chinese utility model patent CN210134221U "a warp knitting filling bag fabric" discloses a warp knitting filling bag fabric, and it is double needle bed fabric, comprises top layer cloth cover and bottom layer cloth cover, and a partpart of this top layer cloth cover and a part of bottom layer cloth cover body coupling form whole cloth piece, do not have between another part of top layer cloth cover and the another part of bottom layer cloth cover to be connected and form the filling bag. The product is a double-needle bed fabric, weaving has unique appearance and structure by controlling the yarn laying motion of guide bars, the guide bars are respectively laid on the adjacent needle beds to form loops without any traction and respectively become single-needle bed fabrics according to a design scheme, and then the yarn laying motion of the guide bars is changed to connect the two fabrics to form an integral cloth piece. The local area without any connection between the two layers of fabric, that is, where the filled bladder is formed; and the functionality of the vamp cloth is increased by a filling method at the later stage.
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.
