Continuous fiber winding device and winding method

Abstract

The invention discloses a continuous fiber winding device and a winding method. The continuous fiber winding device is composed of a rack, and a driving system, fiber winding systems, a forward and reverse rotating system and the like, which are arranged on the rack; the driving system and the forward and reverse rotating system are connected with the fiber winding systems by meshing of gears; two sets of independent fiber winding systems are symmetrically arranged on two sides of the rack; multiple sets of fiber fixing modules are uniformly distributed on a rotary disk of each fiber winding system in the radial direction; a fiber pressing mechanism is arranged on each fiber fixing plate; a gear switching mechanism is arranged in the driving system, so that the driving system can alternatively drive two sets of fiber winding systems to realize continuous winding of fibers; the forward and reverse rotating systems enable the two sets of fiber winding systems to rotate at the same rotating speed in different directions under the driving of a forward and reverse rotating gear set so as to realize cross winding of the fibers. The continuous fiber winding device is high in fiber winding efficiency and low in energy consumption, has a simple structure and is simple and convenient to operate.

AI Technical Summary

Problems solved by technology

[0004] However, the above technologies and winding devices usually have the following problems: 1. After the tube core is extruded, in order to ensure sufficient winding strength, it needs to be cooled and solidified, and then the fiber material coated with plastic is wound and heated, and it needs to be heated when coating the outer layer material. , high energy consumption; 2. Due to the poor fluidity of thermoplastics, when the fibers are poorly impregnated, it is easy to contain air bubbles in the process of winding and coating the outer material, and the cross-section bonding performance is poor, which affects the strength of the pipe body; 3. The fiber winding device is complex , the fiber traction damping is large, and the energy consumption is large; 4. When the fiber on the rotary disc is exhausted, it needs to be stopped to replenish, which affects the continuity of fiber winding; 5. In order to achieve cross winding, two sets of fiber winding are usually used along the extrusion direction. Equipment, the distance between the two fiber winding points is large, the bonding performance of the fiber and the extrusion surface is affected, and the energy utilization rate is low
