Automatic slack bobbin winder

Abstract

The invention discloses an automatic slack bobbin winder, comprising a winding device, a variable amplitude yarn guide device, a fixed-length control device, a tension regulating device and a host control device, all of which are arranged on a frame and driven by a friction roller motor and a groove drum motor, respectively, wherein the winding device comprises a winding rack, a friction roller and a groove drum; the variable amplitude yarn guide device comprises a variable amplitude guide rail, a tension spring, a movable pull rod and an adjustable rotating rod; and the fixed-length control device comprises an infrared light-operated yarn detector, a wire cutter, an alarm indicator lamp and a reset button, as well as a singlechip for controlling the devices, wherein the singlechip is connected to the host control device through an RS-485 bus. In the technical scheme, the automatic slack bobbin winder is simple in structure, rational in design, low in cost, and low in noise; and when in use, the automatic slack bobbin winder is capable of conveniently and accurately realizing the functions of pineapple-shaped forming, fixed length and automatic stopping on yarn breakage, and capable of realizing high-quality slack winding, improving the quality of dyeing in subsequent procedures and achieving smooth unwinding, thus improving the working efficiency and economic benefit of factories.

Description

technical field [0001] The invention relates to the field of textile machinery equipment, in particular to an automatic loose winder. Background technique [0002] With the enhancement of people's aesthetic awareness and the improvement of living standards, high-grade yarn-dyed products are becoming more and more popular. Not only real silk, chemical fiber silk, rayon, blended yarn and cotton yarn can also be made of dyed silk. The most economical dyeing process of colored yarn dyeing is to directly dye the package, so it is widely used. Generally, before dyeing the yarn bobbin, it is necessary to wind the purchased gray yarn or bobbin into a "loose bobbin" suitable for bobbin dyeing for the next process, so the demand for loose bobbins is increasing day by day. How to produce qualified loose bobbins and packages to facilitate even dyeing of bobbins has become a problem that people need to start solving. [0003] The loose-type winding machine generally has the following ...

AI Technical Summary

Problems solved by technology

[0004] The existing automatic loose-type bobbin winder has the following defects in use: 1. The main work is to realize the anti-folding design during winding, ignoring the appearance and structure of the loose-type bobbin itself, which also affects the smooth completion of the subsequent dyeing process One of the reasons is that the edge yarn rings of the parallel or rectangular loose bobbins are too tight, which may easily cause uneven dyeing of the tight edge bobbins; second, the fixed length and yarn break self-stop requirements for loose bobbins when winding, The existing device is relatively complicated and the cost is high; 3. The anti-folding design during winding is relatively complicated and the cost is high; 4. The lateral reciprocating motion of the yarn is not separated from the winding motion during use, but the slot The drum is used not only as a yarn guide, but also as a friction roller to drive the circular motion of the yarn drum. Using the groove of the drum to guide the reciprocating movement of the yarn will easily lead to defects such as yarn overlap and wool; 5. The connection design between the components is not enough Reasonable, high energy consumption during use
