Description

Spinning tension compensation device of roving frame

Technical Field

The utility model relates to a spinning machine equipment technical field, concretely relates to fly frame spinning tension compensation arrangement.

Background

The textile machine twists a plurality of vegetable fibers together into threads or yarns, which can be used to weave into cloth. The earliest spinning machines were very simple in construction and were used beginning in the 14 th century. After the 18 th century, better spinning machines were invented, which made the textile industry the first major industry. All spinning machines do only two things: firstly, a large amount of short fibers are polymerized into loose cotton threads, then the cotton threads are drawn out little by little and twisted into fine cotton threads, and the cotton threads are lengthened after twisting.

The twist of the yarn itself causes the fibers to naturally and tightly bind together, thereby facilitating weaving or knitting. Where the twist of the yarn is related to the diameter of the yarn, the measure is determined by the number of turns in each inch of yarn and is expressed as low, medium or high, generally the higher the twist, i.e. the more turns of the yarn, the better the strength of the yarn. Low twist yarns are commonly used to make smooth, glossy or soft, matte fabrics; conversely, fabrics with a wrinkled feel or rough surface require high twist yarns to make.

In the prior art, in a winding device of a spinning machine, tension compensation curve plates (rods) are adopted for adjustment for the phenomena of large tension at two ends and small tension in the middle of yarns. The curve is not suitable for spinning cone barrels, particularly when a cone-shaped large spindle distance bobbin is wound, the formed bobbin is soft in small end, hard and solid in large end and poor in forming due to different winding speeds at large and small diameters and tension change of yarns in the winding process, and meanwhile when a traditional tension compensation device is used for outgoing yarns, a large amount of heat is easily generated due to the fact that the yarns are subjected to large friction force of a winding wheel, and due to the fact that the heat cannot be dissipated timely, the moisture regain of cotton rolls, rough yarns and the like is unstable and the like.
