Description

Flat yarn preventing turnover mechanism for warping creel

Technical Field

A flat yarn preventing turnover mechanism for a warping creel belongs to the technical field of warping creels.

Background

In the process of warping, the bobbins need to be inserted into the bobbin creel so as to facilitate yarn extraction and tension adjustment, then the yarns on the bobbins are wound on the warp beam in parallel according to the set number, length and width, and the yarns wound on the warp beam in parallel are warp yarns. The flat wire is a flat plastic wire with gold and silver luster and has a front surface and a back surface. When the flat yarns and the fiber yarns are wound in parallel and are used as warp yarns together, the warp yarns can bring golden and silver gloss, and a special fabric style is formed.

In the prior art, a plurality of horizontal support rods are fixedly connected to a bobbin creel, each cheese is inserted into one horizontal support rod, and the bobbin cannot rotate under the action of gravity of the bobbin, so that twisting can be generated on the yarns in the process of extracting the yarns from the bobbin.

The applicant has found that the existing creels have the following problems when warping flat yarns: firstly, in the prior art, the flat filaments are easy to twist and reverse to form a twist shape, which affects the fabric effect. Because the common yarns are fiber yarns which are not divided positively or negatively and are provided with twist, even if the cheese is twisted and reversed during drawing, the common yarns have no obvious influence on the woven fabric. However, the flat filament has both sides, and under the twisting action, the warped flat filament is twisted into a twisted shape on a warp beam, and the twisted flat filament is easy to break due to friction with weft yarns and heald buckles in the weaving process. In order to solve the problem, the prior art mostly adopts a low-speed operation warping machine, and when the flat yarn is twisted and accumulated, the flat yarn is stopped, the bobbin is adjusted, and then the warping is continued. Or the horizontal support rod is changed into a driving rod capable of rotating through a motor to drive the bobbin to rotate so as to avoid twisting, but the design cost is high, and the tension of the flat filament is difficult to control; if the horizontal support rod is changed too much, the horizontal support rod can only be inserted with a flat yarn bobbin once being changed, and the fabric style is not favorably changed.

Secondly, the tension of the flat filament is difficult to control, the existing tension control mechanism is designed aiming at the fiber yarn, the strength of the fiber yarn is far higher than that of the flat filament, and the tension of the flat filament is difficult to accurately control by adopting the existing tension control mechanism; the flat filament is easy to break, and the quality of the fabric is affected due to obvious joint defects after the flat filament is broken.

1. the utility model discloses a warping creel is with preventing flat filament tilting mechanism can prevent the flat filament upset, can realize high-speed warping. The upward pulling force of the flat wire is utilized to drive the bobbin to rotate and feed the wire, thereby avoiding the twisting of the flat wire. In the process of the rotary wire feeding of the bobbin, when the bobbin rotates at a high speed, the contact between the inner wall of the bobbin and the support column is less, and the resistance is less. The yarn guide holes play a role in limiting the pulling direction of the flat yarns, and the yarn guide holes are positioned above the yarn guide holes and can effectively pull the bobbin to rotate. The bobbin can move up 1-3 cm along the support in the rotating wire feeding process, so that the length of the support is designed to be 1.3-1.8 of the length ratio of the bobbin: 1.

2. the utility model discloses a warping creel is with preventing flat filament tilting mechanism can effective control flat filament tension, and the cost is lower. And adjusting the rotating rod to adjust the included angle between the bobbin and the horizontal plane so as to adjust the tension. When the bobbin is vertical to the horizontal plane, in the process of rotating the bobbin to feed wires, the contact between the bobbin and the support is less under the high-speed rotation of the bobbin, the friction force is less, and the flat wire tension is minimum; along with the reduction of the included angle between the bobbin and the horizontal plane, under the action of gravity, the friction force between the bobbin and the support is increased, the resistance for pulling the flat filament is increased, and the tension of the flat filament is gradually increased. Therefore, the tension can be adjusted by adjusting the inclination angle between the bobbin and the horizontal plane. And tension scales are arranged on the scale plate so as to adjust the tension.

3. The utility model discloses a warping creel is with preventing flat filament tilting mechanism easy dismounting, the nimble replacement of being convenient for between flat filament bobbin and fiber yarn bobbin. In actual production, the flat yarns are only the decorative parts in the fabric, and the distribution positions of the flat yarns on the warp beam are changed. The utility model has the advantages that the design is convenient to disassemble and assemble, the flat yarn can be packaged at present, the horizontal support rod at the corresponding position on the creel is refitted on site according to the distribution position of the flat yarn on the fabric warp beam, and the flat yarn warping can be carried out; and after the warping is finished, the horizontal supporting rod can be quickly changed back, and the warping machine can be continuously used for warping fiber yarns.
