The invention discloses an electrostatic spraying device for thermoplastic prepreg production and manufacturing. The electrostatic spraying device comprises a main box body, and an upper cavity and a lower cavity are formed in the main box body; a plurality of fixing frames are arranged in the upper cavity, an upper fixing shaft and a lower fixing shaft are arranged on the fixing frames, and a plurality of spray guns are arranged on the fixing shafts; a first negative pressure generating device is connected into the lower cavity, a second negative pressure generating device is connected into the recycling cavity, and the pressure intensity of the first negative pressure generating device is higher than that of the second negative pressure generating device. The device is divided into the upper cavity and the lower cavity, when the device is used, a fiber bundle to be subjected to electrostatic spraying enters from one side of the upper cavity and is drawn out from the other side of the upper cavity, in the moving process, the electrostatic spraying guns installed on the upper fixing shaft and the lower fixing shaft conduct uniform electrostatic spraying on the upper face and the lower face of the fiber bundle, and it is guaranteed that resin on the upper face and the lower face of prepreg is uniform.
Description
technical field [0001] The invention specifically relates to an electrostatic spraying device for manufacturing thermoplastic prepregs. Background technique [0002] Electrostatic powder spraying, as a manufacturing method of continuous fiber reinforced thermoplastic prepreg, is more and more used in the preparation process of thermoplastic materials. In order to ensure that as many numerical materials as possible can be attached to the surface of the substrate, a relatively advanced process method It is to add resin to the prepreg by electrostatic spraying. [0003] Most of the existing electrostatic spraying resin powder devices have only one electrostatic spray gun, and the angle and height are not adjustable. They are often used for the production of laboratory-level products, and it is difficult to apply them to large-scale industrial production. Contents of the invention [0004] The purpose of the present invention is to solve the above deficiencies in the prior ar...
