Variable-amplitude filament guide device for automatic soft bobbin winder

Abstract

The invention discloses a variable-amplitude filament guide device for an automatic soft bobbin winder. The variable-amplitude filament guide device comprises a variable-amplitude guide rail, a tension spring, a moving pull rod and an adjustable rotary rod, which are connected with a groove drum with a cover plate, a spinning head with a guide block and a winding frame. A slide groove for limiting sliding of the guide block is formed in the middle of the variable-amplitude guide rail, and one side of the variable-amplitude guide rail is movably mounted on the inner side of the cover plate of the groove drum while the other side of the variable-amplitude guide rail is fixed onto the groove drum through the tension spring. The moving pull rod is mounted at one end, extending out of the groove drum, of the variable-amplitude guide rail and connected with the adjustable rotary rod which is mounted on the winding frame and arranged on the same side with the moving pull rod. The variable-amplitude filament guide device is simple in structure, reasonable in design and low in cost, pineapple-shaped forming can be conveniently realized in use of the variable-amplitude filament guide device, high-quality soft winding can be realized, dyeing quality in subsequent procedure and smoothness in rewinding can be improved, and accordingly operating efficiency and economic efficiency of factories can be improved.

Description

technical field [0001] The invention relates to the field of textile machinery and equipment, in particular to a variable-amplitude yarn guide device of 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] Loose winding...

AI Technical Summary

Problems solved by technology

[0004] The existing automatic loose winding machine mainly has the following aspects in terms of how to produce qualified loose winding: the main work is done to realize the anti-folding design during winding, and the appearance structure of the loose bobbin itself is also affected. One of the reasons for the smooth completion of the dyeing process is that the edge yarn loops of the parallel or rectangular loose bobbins are too tight, which is easy to cause tight edge bobbins and uneven dyeing
