Composite tension control system

Abstract

The invention discloses a combined type tension control system which is composed of a main controller, a total tension adjusting mechanism and branch tension adjusting mechanisms arranged corresponding to all fiber unwinding shafts in a complete set mode, and any branch tension adjusting mechanism comprises a brake unit, a first yarn guide roller set and a branch tension sensing roller integrated with the first yarn guide roller set. Wherein the brake unit is fixed on a creel of the winding machine, and a yarn corresponding to a yarn roll is connected to the first yarn guide roller group in a penetrating manner and is in contact with the sub-tension sensing roller; the total tension adjusting mechanism comprises a whole set of second yarn guide roller set and a total tension sensing roller, the multiple strands of gathered yarn are connected to the second yarn guide roller set in a penetrating mode and make contact with the total tension sensing roller, and the braking units and the tension sensing rollers are in signal interconnection with the main controller. By applying the composite tension control system, the internal stress level and distribution consistency of different batches of winding products can be improved, the stress on the inner layer and the outer layer is uniform, the mechanical property advantages of fibers are fully played, the fiber consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to an optimization system for improving the performance of a winding machine that has been put into use, in particular to a system that can achieve balanced tension control for each single yarn group in the winding machine and total tension adjustment for multi-strand gathered yarns. Background technique [0002] Winding molding is a common molding method for composite materials. Matrix resins can be divided into thermoplastic resins and thermosetting resins according to whether they undergo chemical changes when heated. According to the different physical and chemical states of the matrix resin during winding, it can be divided into dry winding, wet winding and semi-dry winding. No matter what kind of winding method, the requirements for tension are very high, and the stability of tension directly affects the quality of winding products.

Problems solved by technology

[0003] The existing winding machine is put into production and molding in practical applications. The molding results of different batches reflect that the products have large performance fluctuations and unsatisfactory yields.

In addition to the slight differences in the winding substrate itself and the process parameter environment, the imbalance of tension control during the operation of the winding machine has become a major cause
