Technical Field

The invention relates to a synchronous feeding system, in particular to a multi-wire-winding-head synchronous feeding system.

Background

With the rapid development of science and technology, resin and glass fiber are continuously improved in technology, composite material wound products are more and more widely applied in various industries, and higher requirements are provided for the performance of the products, wherein container products and cylindrical and large cone combined containers (large aperture ratio, large cone angle and the like) need to be completely wound by a plurality of process layers due to higher performance requirements, and the following problems exist if a conventional single-winding-head winding mode is adopted:

1. in general, the ratio of the diameter of the cylinder body in the middle section to the diameter of the pole holes at the two ends is very large, so that the winding angle is very small (the winding angle is the arcsine of the ratio of the diameter D of the pole holes to the diameter D of the cylinder body).

2. Since a plurality of yarns separated independently from each other are drawn out after being combined into one ribbon from one winding head, the lengths of the yarns on the left and right sides are inevitably inconsistent due to the bending radius when the winding direction is changed, so that friction is generated between the yarns to cause fuzzing of the yarns, the tensions are also different, and the performances of the raw materials cannot be fully exerted.

3. In order to ensure stable winding, the yarn consumption is limited inevitably, and as a result, on one hand, the production efficiency is limited greatly, the time for exposing the resin is prolonged inevitably, so that the performance of raw materials and the performance of cured finished products cannot be well exerted, even the winding process must be modified, on the other hand, the serious overhead phenomenon (the phenomena of fewer cut points, larger aperture ratio and narrower yarn bandwidth are serious) caused by the repeated overlapping of fiber belts appears near the polar holes, at the moment, the shape near the polar holes is changed, and has a larger difference with the shape when winding is started, so that the yarn falling track is directly influenced, the uneven distribution of the yarn belts on the surface of the products is caused, and the normal winding work can not be carried out any more sometimes.

In order to give full play to the properties of raw materials as much as possible, meet some special process requirements and further improve the production efficiency, the number of yarn groups is increased as much as possible during winding, and the traditional single-winding-head winding mode cannot meet the requirements.

In summary, the conventional single-winding-head winding method has the problems of low winding efficiency and incapability of fully exerting the performance of raw materials.

Preferably, the guide wheel mechanism comprises a horizontal roller and a vertical roller, and the horizontal roller and the vertical roller are sequentially arranged on the feeding mechanism fixing plate seat from front to back.

Maintaining a stable and sustained low tension is essential for winding special articles (such as grains, rubber balloons, etc.) that especially impose low tension requirements. In addition, each winding head only uses one yarn, so that a yarn dividing comb is not needed, and the phenomenon that the winding tension is suddenly and sharply increased due to accidental blockage of the yarn passing window or the yarn comb in the whole process of passing through the yarn passing window in the yarn is avoided.
