A Synchronous Collection Mechanism for Isolation Film of Thermosetting Fiber Prepreg Tape

Abstract

The invention discloses a thermosetting fiber prepreg tape isolation film synchronous collection mechanism. When the prepreg tape release roller on the tape release mechanism is driven by a motor to rotate, the synchronous belt drive drives the film collection roller in the film collection mechanism to rotate and collect and isolate. membrane. There is a friction plate in the film winding mechanism. With the unwinding process, the diameter of the prepreg tape material tray decreases and the diameter of the film winding material plate increases. By adjusting the fastening degree of the synchronous wheel of the film winding mechanism and the friction plate, the power of the friction plate is reduced. The transmission capacity makes the film winding roller and the synchronous wheel rotate relative to each other, ensuring that the unwinding line speed is consistent with the film winding line speed, and realizing the synchronous progress of prepreg tape unwinding and isolation film collection. The present invention is different from the traditional dual-motor control, only one motor is needed for control, and the control method of the real-time adjustment of the rotating speed with the change of the diameter of the material tray is not easy to pull and break the tape, and realizes the prepreg tape of carbon fiber reinforced thermosetting resin matrix composite material The isolation membrane efficiently and stably separates and collects simultaneously.

Problems solved by technology

[0004] The existing prepreg tape unwinding device usually uses dual motors to drive the unwinding roller and the film rewinding roller separately. On the one hand, the space and weight of the unwinding device are increased, so that the unwinding device cannot be integrated with the laying head and installed independently. The prepreg tape needs long-distance transmission, the tension fluctuates greatly, and the probability of tape interruption increases during the transmission process; The speed of belt motor and wrapping motor needs to be adjusted in real time to ensure that the linear speed of prepreg and separator is consistent. The control method is complicated. Once the speed is out of adjustment, it is easy to cause the separator to accumulate or break, and the reliability is low.
