By setting an anti-entanglement yarn-separating device, the yarn can be combed by a first sorting roller and the sorting circles on it.

Description

Technical Field

[0001] This invention belongs to the field of knitted fabric preparation technology, specifically to knitting machines for knitted fabrics and their preparation processes. Background Technology

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the form of the yarns within the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products, and are loved by consumers. The preparation of knitted fabrics involves specific processes; good processes can improve production efficiency and reduce defect rates.

[0003] Existing knitted fabrics and their preparation machines mainly include a knitted layer and a functional layer covering the knitted layer. The preparation machine is mainly a knitting machine, which mainly includes a machine body, a winding bobbin, multiple drive rollers, a knitting mechanism, an operating table, and external drying and collection devices fixedly installed thereon. In use, the yarn is wound on the winding bobbin, and then transported to the knitting mechanism under the action of the drive rollers, and then dried after forming.

[0004] However, in the actual production process, when the yarn is interlaced, due to the large number of yarn strands, it is easy for them to cross and entangle when interlacing together, which leads to defects in the produced fabric. After the yarn is produced, the surface is generally dull and requires separate brightening treatment of the fabric. This is not only time-consuming and labor-intensive, but the brightening treatment of the outer surface of the fabric after production is often short-lived. Summary of the Invention

[0015] The manufacturing process of knitted fabrics includes the following steps: S1. Yarn making and dyeing: The yarn is installed with a straight line in the middle, and two spiral lines are interwoven on the outer surface of the straight line. The yarn is then placed in a dyeing vat for dyeing, and the dyed yarn is wound onto a winding bobbin. When the machine is started, the yarn on the winding bobbin can be driven through the first drive roller, and then the yarn can be separated under the action of the first sorting roller. Under the action of the second sorting roller, three strands of yarn are grouped together and cross-wound, which can prevent them from getting tangled together during the winding process. S2. Fabric setting: The wound yarn can be made into fabric by the knitting mechanism, and then transported on the operating table. Then, under the action of the second transmission roller, the set fabric can be transported into the liquid container. S3. Polishing process: The shaped fabric is wound around the third transmission roller and then transported to the drying plate through the second rectangular through hole. At this time, the fabric can be soaked in polishing liquid inside the liquid frame and its outer surface is polished. The first motor can drive the first gear to rotate, which in turn drives the second and third gears to rotate, which in turn drives the fixed rod and the arc plate to rotate, thereby mixing the polishing liquid in the liquid frame and preventing sedimentation. S4. Drying: When the polished fabric is transported to the drying plate, the power supply and the second motor are turned on.

[0017] (III) Beneficial Effects Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The knitted fabric using a knitting machine and its preparation process, by setting a polishing layer and a liquid placement frame, the polishing liquid inside the liquid placement frame can form a polishing layer on the outer surface of the fabric, thereby improving the overall brightness of the fabric. Moreover, the polishing layer is formed during the production process and belongs to the functional layer of the fabric, which is not a temporary brightening effect. By setting an anti-entanglement yarn separating device, the yarn can be combed by the first sorting roller and the sorting round blocks thereon to avoid entanglement. Under the action of the second sorting roller and the yarn separating arc blocks, individual yarns can be combed, thereby allowing the yarns to be sorted individually and simultaneously sorted a second time for three yarns produced at the same time, thereby avoiding the yarn entanglement phenomenon during the production process and reducing defects in the finished product.

[0018] 2. The knitting machine and its manufacturing process for this knitted fabric, by setting a first threaded rod, a threaded hole plate, a stop plate, and a rubber clamping plate, allows the threaded rod to drive the threaded hole plate to move, which in turn drives the stop plate and the rubber clamping plate to move. The arc-shaped edge on the stop plate can abut against the dividing arc block when it rotates, thereby restricting its rotation and preventing it from rotating in the fabric transmission direction, thus playing a fixing role. Under the action of the rubber clamping plate, the sorting circle block can be fixed with the semi-circular arc groove, thereby limiting the sorting circle block and preventing it from rotating, thus achieving a fixing effect.

[0019] 3. The knitting machine and its preparation process for this knitted fabric, by setting up a polishing and drying device, the polishing liquid in the liquid-filled frame can polish the fabric, which can improve production efficiency and save the time of individual polishing. When the fixed rod and arc plate in the liquid-filled frame rotate, the liquid in the liquid-filled frame can be mixed to avoid sedimentation, thereby saving the time consumed by repeated manual stirring. With the cooperation of components such as the drying plate, the fabric can be dried faster, saving drying time and thus improving production efficiency. Attached Figure Description

S4. Drying: When the polished fabric is transported to the drying plate 799, the power supply 7915 and the second motor 7918 are started. The power supply 7915 can make the heating tube 7916 generate heat, and the second motor 7918 can drive the fan blade 7919 to rotate, thereby blowing the heat emitted by the heating tube 7916 onto the fabric to accelerate heat dissipation.
