Cheese bobbin core with unwinding protection function

Abstract

The invention provides a cheese bobbin core with an unwinding protection function. The cheese bobbin core comprises a paper bobbin and further comprises an unwinding protection device. The unwinding protection device comprises an inner cylinder made of plastic, and an end cover made of stainless steel is arranged at the top end of the inner cylinder. The inner cylinder is inserted into an inner cavity of the bobbin, and the inner cylinder is in interference fit with the inner cavity of the bobbin. The top end of the bobbin is wrapped with the skirt of the end cover. At least two spring piecesare arranged at the bottom end of the inner cylinder in the length direction of the inner cylinder, and the spring pieces are arranged on the inner cylinder in a tensioned manner. Each spring piece isof an arc-shaped structure, and a convex part of each spring piece is in contact with the inner wall of the inner cylinder. By the adoption of the cheese bobbin core, the stability of cheese unwinding operation can be improved, the production failure is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to textile equipment, in particular to a loom cheese. Background technique [0002] Cheese yarn is a common material in the textile industry. In the prior art, the cores of cheese yarn are mostly cylindrical bobbin and conical bobbin. Both kinds of bobbins are made of hard paper. All will be subjected to external pressure, and over time, the bobbin will be deformed, especially the edge of the paper bobbin is severely worn, resulting in irregular shape or burrs on the edge of the bobbin, so that it is easy to cause the bobbin to unwind during the weaving process of the loom If it is blocked, the yarn is wound on the paper at the edge of the mouth of the bobbin, which will cause the stoppage of the weft insertion movement; or the deformed bobbin cannot be unwound normally during weaving, resulting in the weft insertion failure and even the stoppage phenomenon. Its adverse effects include: first, reduce production efficiency and cau...

[0002] Cheese yarn is a common material in the textile industry. In the prior art, the cores of cheese yarn are mostly cylindrical and conical. They will be pressed by external force, and over time, the bobbin will be deformed, especially the edge of the paper bobbin is severely worn, resulting in irregular shape or burrs on the edge of the bobbin, so that it is easy to cause the bobbin to unwind during the weaving process of the loom If it is blocked, the yarn is wound on the paper at the edge of the mouth of the bobbin, which will cause a stoppage effect on the weft insertion movement; or the deformed bobbin cannot be unwound normally during weaving, resulting in weft insertion failure and even a stoppage phenomenon

Its adverse effects include: first, it reduces production efficiency and causes losses to the production of the enterprise; second, due to the phenomenon of weft yarn jamming, the cloth crosspiece is serious; third, the bobbin is unstable during unwinding, and the The remaining small packages can only be discarded, resulting in increased weaving costs
