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
During normal operation of the warp knitting machine, warp yarns are unwound from the warp beam and fed into the looping system according to a certain let-off amount for knitting by the looping machine, and the process is called let-off. The mechanism that accomplishes this is called the let-off mechanism. Let-off mechanisms are divided into two main categories, passive let-off and active let-off. All creel yarn supplies 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 through the transmission device by the main shaft of the warp knitting machine to send warp is called as an active warp sending mechanism. The main looping machine parts of the warp knitting machine are provided with knitting needles, yarn guiding needles, sinkers and pressing plates. The guide bar is a device on which a yarn guiding needle is arranged and guides and drives yarn to make yarn-laying movement. The warp yarn passes through the eyelet of the yarn guide needle, is wound on the needle along with the motion of the guide bar, and is woven into the fabric through the mutual matching motion of knitting needles, sinkers and other looping parts.
The fly-knitting integrated vamp is a single-layer or multi-layer vamp integrally knitted by a brand new knitting process by utilizing a 3D integrated molding technology. In the later production, the fly-knitting integrated vamp is directly formed with the sole, so that various procedures of the traditional vamp are greatly reduced, nine vamp needle lathers can be saved, vamp production efficiency is greatly improved, and the production mode of the traditional sports shoes is overturned, therefore, the fly-knitting integrated vamp production technology in recent years is rapidly developed. When the double needle bar warp knitting machine is used for shoe upper mass production, the working width of the warp knitting machine can be used for arranging a plurality of shoe uppers side by side, and the rest part of the whole cloth is non-shoe upper area leftover materials for connection except the shoe upper materials. In the later finishing, only one integral vamp needs to be cut along the outline of the vamp, and the excessive leftover materials in the non-vamp area are discarded or recycled.
Further information about the above solutions can also be found in the following documents. The Chinese patent application CN108914361A "a super-woven shoe material fabric" discloses a fabric which is woven by a yarn-pressing double jacquard warp knitting machine, wherein two separated jacquard combs are formed into a relief yarn-pressing pattern before yarn pressing, yarns are wound at the root of a coil, pressed mutually, and the fabric is firm and firm. The yarn pressing plate is provided with a chain knitting coil at the back, the yarn before pressing is sleeved and strung, and the fabric structure is compact. The two separated jacquard combs in front of the yarn pressing plate are matched with each other for use in jacquard functions, and the thickness and meshes of the jacquard combs are designed according to different positions, so that ventilation holes, shoelace holes, thin contour edges, convenient cutting and the like can be formed. Can be used for wearing various color raw materials, and can be used for jacquard weave into rich patterns, required trademarks and the like. The terylene material is adopted, and the terylene has high strength, consistent dry and wet state, good elasticity, good wear resistance and good light resistance, so that the formed fabric is suitable for outdoor complex environments. The Chinese patent No. 210134221U discloses a warp knitting filling bag fabric which is a double needle bed fabric and consists of a surface layer cloth cover and a bottom layer cloth cover, wherein one part of the surface layer cloth cover and one part of the bottom layer cloth cover are integrally connected to form an integral cloth piece, and the other part of the surface layer cloth cover and the other part of the bottom layer cloth cover are not connected to form a filling bag. The product is double-needle bed fabric, the fabric is provided with unique appearance and structure by controlling the yarn-laying movement of the guide bars, the guide bars are respectively laid on the needle beds close to each other to form loops according to the design scheme, no any involvement exists between the guide bars, the guide bars are respectively single-needle bed fabric, and the two fabrics are connected by changing the yarn-laying movement of the guide bars so as to form an integral piece of fabric. A localized area where there is no link between the two layers of fabric, i.e. where the filled bladder is formed; the functionality of the vamp cloth is increased by a filling method in the later period.
However, in the existing warp knitting and fly weaving integrated vamp production process, since the jacquard and the bottom comb are fed by the warp beam disc heads, the warp feeding amount is constant when the integrated vamp grey cloth and the leftover materials are woven, and therefore the loss of the leftover materials in the whole width cloth fabric is larger. Some of the warp let-off tension is adjusted to cause the stability of the whole cloth to be reduced due to improper operation, so that technical breakthroughs are urgently needed on the basis of guaranteeing the stability of the width of the lower machine and saving the yarn consumption.
Disclosure of Invention
In view of the above-mentioned technical problems in the background art, there is a need to provide a yarn feeding device, a warp knitting machine and an application of a double needle bed jacquard machine for saving yarns. The yarn feeding device and the warp knitting machine of the double needle bed jacquard machine capable of saving yarns can adjust the yarn feeding amount of different areas on the width according to different requirements, and the yarn feeding device and the warp knitting machine of the double needle bed jacquard machine capable of saving yarns can enable the weft width stability to be strong in later-stage machine feeding, the yield and the quality of vamp finished products are not affected, the leftover material loss of non-vamp areas of yarns is greatly reduced, and the purpose of reducing vamp production cost is achieved.
To achieve the above object, in a first aspect of the present invention, the present inventors provide a yarn feeding device of a double needle bar jacquard machine saving yarns, comprising a guide bar cradle, a guide bar L1, a guide bar L2, a guide bar L3, a guide bar L4, a guide bar L5 and a guide bar L6, wherein the guide bar L1, the guide bar L2, the guide bar L3, the guide bar L4, the guide bar L5, the guide bar L6, the guide bar L7 and the guide bar L8 are sequentially fixed on the guide bar cradle from a front needle bar to a rear needle bar along the double needle bar jacquard machine.

The jacquard bar in the original machine type is divided into two half jacquard bars, so that the two jacquard bars in the original machine type are changed into four half jacquard bars which are respectively named as jacquard bar L1, jacquard bar L2, jacquard bar L3 and jacquard bar L4, and therefore, the yarn feeding device of the double needle bed jacquard machine is an eight-bar double needle bed jacquard warp knitting machine which is formed by four jacquard bars and four ground bars. In the original double-needle bar warp knitting machine for vamp weaving, eight guide bars are adopted, but due to the fact that the yarn feeding mode of the pan head is adopted for positive yarn feeding, the vamp finished product area of the whole cloth and the leftover material area formed by the adjacent vamp are all looped in the weaving process, so that the leftover material area is also formed into a relatively compact area, and the waste of yarn raw materials is caused. Therefore, the main improvement point of the invention is to distinguish the yarn feeding mode of the finished fabric area and the leftover material area of the product, so that the leftover material area adopts the yarn feeding mode of the creel to carry out negative yarn feeding. Thus, the jacquard device of the jacquard controls the leftover material area to form a thinner area, thereby achieving the purpose of saving yarn raw materials.
