Description

Creel for warping ultrafine metal wire

technical field

The utility model relates to the technical field of textile devices, in particular to a creel used for warping superfine metal wires. the

Background technique

Warping is to wind the package yarns on the pan head in parallel, constant speed and neatly under the same tension according to the number and length of warp yarns required by the process, which is a crucial preparation process in warp knitting. Ensuring the uniform warping tension of each warp yarn is the key to the smooth progress of the subsequent weaving process and the quality of the product. The warping creel is to place the bobbins, and generally consists of a frame, a bobbin fixing frame, a bobbin support frame, a tensioner and other components. Generally, the creel also has functions such as tension control, automatic stop of yarn breakage and signal indication. These functions have an important impact on improving warping quality and warping efficiency. Therefore, choosing a suitable creel is of great significance for improving warp warping quality. . the

At present, the warping creel mostly adopts the axial unwinding method. The warping bobbin unwound in the axial direction is a conical bobbin, and the warp unwinding bobbin does not need to be rotated, which is beneficial to the improvement of warping speed and quality, and can increase the bobbin package capacity. However, when warping ultra-fine wire yarn, the metal wire itself is very rigid, so when the wire yarn is unwound from the bobbin in the axial direction, it is easy to cause yarn breakage and torque winding phenomenon, which will instead Seriously affect the warping quality, and too much friction between the wire yarn and the warping parts, the surface coating will peel off. the

Patent ZL201220729982.4 introduces a special warping creel for metal yarn. This creel adopts the method of tangential unwinding of the warp yarn. The lower wire yarn is always in a straight state and is not prone to self-kinking. Each bobbin in this creel is fixed on the bobbin support shaft by two leather pads on the left and right. At this moment, the fixing force to the bobbin is mainly the frictional force of the leather pads to the bobbin. Because the fixed position of the leather pad depends entirely on the warper's feeling, it is easy to cause deviation. If the fixed position is too tight, the bobbin will rotate slowly, and if the position is too loose, the bobbin will shift left and right when it rotates, and the bobbin cannot be completely fixed by the leather pad. This has caused the yarn bobbin to swing left and right between the two leather pads, and this yarn bobbin moves left and right, which easily causes yarn tension fluctuations and uneven tension. the

And this warping creel is when warping brake, because the frictional force of leather pad to yarn bobbin is less, bobbin can't stop in time under the effect of inertia, causes yarn tension unevenness. the

In addition, as an independent and integral creel, the enveloping angles of the straight-type yarn collecting plate to the yarn at the center of the creel and the yarn at both sides are different, which results in different warp tensions. It is also easy to scratch the yarn. If it is a wire yarn, too much friction will easily cause the surface coating to peel off. the

Contents of the invention

The technical problem to be solved by the utility model is to design a creel for superfine metal wire warping in view of the problems existing in the above-mentioned prior art. This creel adopts an electromagnetic damping tensioner instead of a common tensioning device. Fix the electromagnetic damping tensioner on the "L" type bobbin support frame with magnetic eyes, then fix the bobbin support shaft on the electromagnetic damping tensioner, the bobbin is set on the bobbin support shaft, and the electromagnetic damping tensioner The tension can be adjusted to unify the tension of all electromagnetic damping tensioners. When the warping pulls the yarn to move with a certain tension, the electromagnetic damping tensioner applies the set force opposite to the direction of the bobbin, so that the warping tension is uniform; when the warping stops, the larger electromagnetic damping tension can Effectively prevent yarn tension unevenness caused by bobbin inertial rotation. The use of electromagnetic damping tensioner and tangential unwinding creel keeps each wire yarn in a straight state during the warping process, and the tension is uniform, which also reduces the bending and kink of the wire yarn. The frame is set to be composed of more than two independent sub-frames, which are arranged at a certain angle, and there is a certain distance between each independent frame, which is convenient for warpers to change yarns and join operations. In addition, the wire collecting plate is changed from a straight type to a knuckle type, parallel to each independent frame, so that the enveloping angle between the wire yarn and the hole on the wire collecting plate is approximately a flat angle, which not only makes the warping tension uniform, but also It can reduce the abrasion of the gold-plated layer on the surface of the wire. Because the wire yarn is very thin, it is difficult to find it without careful observation. In order to prevent the damage to the wire yarn caused by uninformed personnel or operators who cannot see clearly, yellow warning bars are set up on both sides of the creel. the

The technical problem required to be solved by the utility model can be realized through the following technical solutions:

When the rack is composed of more than two independent sub-racks, every two sub-racks are not in the same plane and the gap between the sub-racks Separated from each other, the two ends of the bobbin fixing frame are fixed on the frame, the bobbin supporting frame is installed on the bobbin fixing frame, and the tensioner is an electromagnetic damping tensioner and is fixed on the bobbin supporting frame. One end of the bobbin support shaft is inserted into the electromagnetic damping tensioner and the bobbin support shaft can rotate. The bobbin is set on the bobbin support shaft and fixed. Coaxial synchronous rotation, the magnetic damping tensioner gives the bobbin a force in the opposite direction of rotation, so that the yarn on the bobbin controls the tension of the yarn according to the set force value, and the radial surface of the magnetic eye is parallel to the bobbin axis For ensuring the tangential unwinding of the warp yarn, the yarn collecting plate is located in front of the frame and has a yarn collecting hole on it, and the yarn collecting hole corresponds to the magnetic eye. the

The bobbin is fixed on the bobbin support shaft by screws or pins. One end of the bobbin is an electromagnetic damping tensioner, and the other end is supported by a spring cone. The spring cone includes a cone with a hole in the center, a spring and the ring piece, the spring is located between the cone and the ring piece and welded into one, the spring cone top sleeves on the bobbin support shaft, the cone is pushed on the bobbin, and the ring piece is another One end is snapped with a flap. The spring cone top is used to prevent the bobbin from sliding left and right. the

Warning bars are installed on the outermost two sides of the rack. the

The electromagnetic damping tensioner is used to replace the ordinary tensioning device. When the warping pulls the wire yarn to move with a certain tension, the electromagnetic damping tensioner will give a set reverse force to make the warping tension uniform; when the warping When the machine stops, the large electromagnetic damping tension can effectively prevent the uneven tension of the wire yarn caused by the inertial rotation of the bobbin. The wrapping angle between the wire yarns between the wire collecting plates and the wire collecting holes on the wire collecting plates is approximately a flat angle, which can not only make the warping tension uniform, but also reduce the wear on the gold-plated layer on the surface of the metal wires. the

Due to adopting the above technical scheme, the utility model has the following characteristics:
