Background
One of the main products of continuous fiber reinforced thermoplastic Composite (CFRT) is a unidirectional continuous fiber reinforced thermoplastic composite, which is prepared by withdrawing continuous fiber yarn from a yarn bobbin, drawing, spreading the yarn, and compounding with thermoplastic resin. The unwinding and tensioning device is required for continuous fiber yarn unwinding, and the conventional method is to tension the yarn tube (pipe) through an O-shaped ring or a rubber ring on the unwinding shaft and utilize the elasticity of silica gel or rubber.
Taking glass fiber as an example, the weight of the yarn for the continuous fiber reinforced thermoplastic composite material is about 20 Kg/spindle, the yarn feeding is carried out manually, and when the yarn is fed, the spindle is pushed in place by manually pushing the spindle and overcoming the deformation resistance of the O-shaped ring. In the continuous unreeling process, the spindle is lighter and can be popped up by the O-shaped ring, so that continuous production is influenced. In addition, the O-shaped ring can age and harden after a long time, the elasticity is lost, the friction force between the O-shaped ring and the yarn barrel is reduced, and the yarn spindle is easy to slip, so that the production efficiency and the reliability are influenced.
