[0002] Traditional methods for making prepreg tapes include solvent method and melt method. However, these methods easily lead to waste of polymer materials such as nylon and polyetheretherketone. Currently, a spraying method has appeared on the market, which can reduce material waste: the thermoplastic resin powder is charged and sprayed through an electrostatic spraying device, and the resin powder is covered on the fiber filament belt that has been expanded into a ribbon through electrostatic action.

[0003] Chinese patent number CN217940575U provides a prepreg tape thickness detection mechanism, a spraying device and a prepreg tape production line, including a lifting bracket, a lever, a floating rod, a floating seat, a support plate, a preload spring and a displacement sensor. The middle part of the lever is hingedly mounted on the top of the movable bracket. The top of the floating rod is hingedly mounted on the end of the lever. The floating seat includes a floating mounting head, an annular end cover and a contact ball, and the annular end cover rotates and seals the contact ball in the circular groove of the floating mounting head. The support plate is horizontally mounted on the lifting bracket. The preload spring is arranged on the support plate and supports the lever. The displacement sensor is mounted on the end of the support plate and faces the lever. The utility model utilizes the principle of a lever, and can collect the thickness of the prepreg tow belt passing through the contact ball in real time, thereby controlling the speed of the subsequent spraying mechanism to control the powder spraying according to the thickness of the tow belt, and improving the powder spraying accuracy of the subsequent powder spraying mechanism.
