Description

Technical Field

[0001] The utility model belongs to the technical field of textiles, and specifically relates to a single-sided structural flannel, in particular to a flannel weaving device of a single-sided machine. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine, has many advantages such as multiple loops, high speed, high output, fast shape change, good fabric quality, fewer processes, and strong product adaptability. It has been widely used in the knitting industry. Circular knitting machines include single-sided circular knitting machines and double-sided circular knitting machines. Double-sided circular knitting machines have two needle cylinders, an upper needle cylinder (commonly known as a needle disk) and a lower needle cylinder, and they are arranged perpendicular to each other, that is, the needle disk and the needle cylinder are arranged perpendicularly at 90 degrees. Single-sided circular knitting machines are machines with one needle cylinder, which only has one needle cylinder for knitting, so they can only weave fabrics with a single-sided structure.

[0003] When a single-sided machine is weaving fabrics, if it is necessary to add a single-sided cut pile structure, the invention patent with the authorization announcement number CN105040251B discloses a terry cutting sinker for a circular knitting machine, including a sheet body, the sheet body including a sheet nose, a sheet jaw, a sheet throat located between the sheet nose and the sheet jaw, a sheet crown located at the top of the sheet body, and a sheet heel matched with the circular knitting machine track. The sheet body is composed of a high heel sinker and a low heel sinker, the high heel sinker and the low heel sinker are tightly attached to each other and move radially through their own triangle controls respectively, the sheet crown of the high heel sinker is provided with a holding part for holding the terry, and the sheet crown of the low heel sinker is provided with an arc-shaped blade, the opening of the arc-shaped blade faces the sheet body and is higher than the holding part, the holding part and the blade are arranged on the sheet body in a staggered manner, the blade is closer to the sheet heel than the holding part, the cutting effect is good, and the terry will not be hooked.

[0004] The above patent realizes the functions of raising, looping and cutting pile by using sinkers on a single-sided machine, but this design leads to a complex structure of sinkers and high motion precision requirements. In addition, multiple sinkers also require different triangular track controls, which further increases the complexity of the machine and the requirements for operating precision. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a flannel weaving device for a single-sided machine with a simple structure.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a velvet weaving device for a single-sided machine, comprising a frame, a needle cylinder and a sinker are provided on the frame, the needle cylinder is provided with knitting needles for weaving a base yarn and a knitting needle triangle for driving the knitting needles to move, the frame is also provided with a sinker for pressing the yarn and a sinker triangle for driving the sinker to move, and is characterized in that the needle cylinder and the sinker cooperate to complete the weaving of the base cloth and the terry loop, the frame is also provided with a cutting mechanism corresponding to the sinker one by one, and when the knitting needle and the sinker cooperate to form the terry loop, the cutting mechanism can cut the looped terry to form a cut loop velvet.

[0007] The principle of the single-sided machine is to use the knitting needles in the needle cylinder to form loops, which usually include starting (retracting the loop), padding yarn, closing the mouth, circling, uncircling, bending yarn, looping, pulling, and so on. The loops are continuously formed to form fabrics. In this application, when padding yarn, the knitting needles simultaneously pad the base yarn and wool yarn. The base yarn is used to weave to form the base cloth, and the wool yarn is used to weave to form the loops. Since the same set of knitting system is used, the base cloth and the loops are tightly embedded. Then the loops are cut by the cutting mechanism to form cut loop pile, thereby forming the base yarn of the single-sided structural fabric and the cut loop pile formed after the loops are embedded and cut. The cut loop pile is embedded in the base cloth, so it is not easy to shed hair. And because the plush is only directly woven, it can be woven with natural fibers, such as plant fibers such as cotton and linen; animal fibers such as cashmere, etc., to adapt to the production of fabrics with different functional requirements in different application scenarios. When the cutting mechanism is cutting loops, since the bottom yarn and the wool yarn are different yarn supply units and the bottom yarn is covered on the outside of the wool yarn after looping, only the bottom yarn can be seen on the back of the finished fabric, and only the loop pile formed after the wool yarn is cut can be seen on the front. The fabric has better aesthetics, and its functionality can be better distinguished from the front and back. In particular, using bottom yarns and wool yarns of different materials and specifications can achieve functional diversification and appearance diversification.

[0008] In the above-mentioned velvet weaving device of a single-sided machine, the cutting mechanism includes a cutter and a cutter triangle for driving the cutter to extend and retract.

[0009] In the above-mentioned velvet weaving device of a single-sided machine, the cutter cam and the sinker cam are integrated; the cutter cam and the sinker cam share the same track. Since a cutter is added, in order to simplify the structure of the single-sided machine, the cutter is not provided with a separate cam, but directly shares the sinker cam, which is more cost-saving and has a simpler structure.

[0010] In the above-mentioned velvet weaving device of a single-sided machine, the sinker includes a sinker body and a sinker foot, the cutter includes a cutter body and a cutter blade foot, the sinker foot is located in the sinker triangular track, the cutter blade foot is also arranged in the sinker triangular track, the width of the sinker foot is smaller than the width of the cutter blade foot, a cutter protruding part is provided on the sinker triangular track, the cutter blade foot can move along the cutter protruding part when sliding on the sinker triangle to realize the protrusion of the cutter, and the sinker foot cannot touch the cutter protruding part on the sinker triangular track.

[0011] The flannel weaving method of the single-sided machine comprises the following steps:

[0012] S1, the needle cylinder eats the bottom yarn and cooperates with the sinker to form a loop to form the bottom fabric;

[0013] S2, the needle cylinder eats the wool yarn at the same time, and cooperates with the sinker to form a loop embedded in the base fabric;

[0014] S3. The cutting knife extends to cut the looped pile to form cut loop pile.

[0015] Compared with the prior art, the utility model realizes cutting of the wool yarn after looping through the cutting structures arranged in one-to-one correspondence with the sinkers. The cut loop pile formed after the pile cutting is located on the front side of the base yarn, thereby weaving a single-sided structure of cut wool pile. The pile is tightly embedded in the base yarn and is not easy to shed. The materials and specifications of the base yarn and the wool yarn can be adjusted according to the requirements of different fabrics to achieve different functions and appearances. The cutting structure shares the sinker triangle, and its structure is simplified, the cost is low, and it is also easy to modify on the existing circular knitting machine.
