Description

Tube support for yarn warping

technical field

The invention relates to the technical field of yarn warping devices, in particular to a bobbin support frame for yarn warping.

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 weaving. 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. .

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 the yarn is unwound from the bobbin in the axial direction, it is easy to cause yarn breakage and torque winding phenomenon, which will seriously affect the warping quality.

Patent ZL201220729982.4 introduces a special warping creel for metal yarn. This creel adopts the method of tangential unwinding of the warp yarn. The 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.

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.
