Embodiment 1

[0023] Continuous fiber reinforced thermoplastic structural sheet and coil production. Continuous fiber reinforced thermoplastic prepreg tape (continuous glass fiber reinforced polypropylene, nylon, PBT, PET, continuous carbon fiber reinforced PP, PET, PBT, nylon, etc.) is actively unwound on the automatic unwinding device 11, and the speed of the traction roller is adjusted. The ratio of its line speed to the line speed of the unwinding roller shaft 11 is greater than 1. Under the action of traction roller shaft 12, the continuous prepreg tape is conveyed into crawler hot rolling unit 4 through front conveying unit 2 for melting and compounding, and the heating device coil is adjusted to adjust the heating temperature of each section. The composited sheet is sent into the first cooling roller 51, the second cooling roller 52, and the third cooling roller 53 for cooling and shaping, the flow rate of the cooling medium is adjusted to control the cooling speed of the sheet, and ...

Embodiment 2

[0025] Production of sandwich panels formed from continuous fiber reinforced thermoplastics and honeycomb materials. Continuous fiber reinforced thermoplastic prepreg tape (continuous glass fiber reinforced polypropylene, nylon, PBT, PET, continuous carbon fiber reinforced PP, PET, PBT, nylon, etc.) is actively unwound on the unwinding roller 3, and the honeycomb materials are laid in sequence On the front conveying unit 2, under the traction force of the conveyor belt and the roller press, the continuous fiber-reinforced thermoplastic prepreg tape is sent into the crawler hot roller press 4 for fusion compounding, and the heating device coil is adjusted to adjust the heating temperature of each section. The composited sheet is sent into the first cooling roller 51, the second cooling roller 52, and the third cooling roller 53 for cooling and shaping, the flow rate of the cooling medium is adjusted to control the cooling speed of the sheet, and the rolling pressure is adjusted ...

Embodiment 3

[0027] Production of cut-to-length continuous fiber reinforced thermoplastic structural panels. Continuous fiber reinforced thermoplastic prepreg tape (continuous glass fiber reinforced polypropylene, nylon, PBT, PET, continuous carbon fiber reinforced PP, PET, PBT, nylon, etc.) is actively unwound on the unwinding roller 11, and the speed of the pulling roller 12 is adjusted , so that the ratio of its line speed to the line speed of the unwinding roller shaft 11 is greater than 1. According to the length requirement of the plate, the timing cutting time is set, and the timing cutting device 13 cuts the multi-layer prepreg tape into a predetermined length. The outer packaging film is actively unwound on the unwinding roller 3, and its linear speed is adjusted to be consistent with the linear speed of the traction roller 12. The cut prepreg tape is sent to the crawler hot roller through the front conveying unit 2 together with the outer packaging film The pressing unit 4 perfo...

Abstract

The invention relates to production equipment for a continuous fiber reinforced thermoplastic structural panel. In the molding process of the panel, a continuous fiber reinforced thermoplastic prepreg tape and a sandwich material are conveyed to a panel compositing place by an automatic conveyer and performed with compression molding by crawler-type hot pressing compositing, and cold pressing molding by a roll shaft. The mode of heating is electromagnetic heating. Compared with prior art, the invention has simple process and high production efficiency and is able to produce continuous panels and large area composite panels. The equipment is suitable for use in sandwich panels formed by the continuous fiber reinforced thermoplastic structural panel and continuous fiber reinforced thermoplastic plastic and composite panels formed by continuous fiber reinforced thermoplastic plastic and metals such as aluminum foil and the like.

Description

technical field [0001] The invention relates to a pressing device for forming a thermoplastic composite board or thermoplastic board, honeycomb board, aluminum foil and other metals to form a composite board, in particular to production equipment for continuous fiber-reinforced thermoplastic structural boards. Background technique [0002] At present, the pressing of composite panels and honeycomb panels at home and abroad mostly adopts flat vulcanizing machine or roller pressing. The former belongs to intermittent production, which has the problem of low production efficiency, and can only produce flat plates of a certain length and width; the finished product is high in roller pressing efficiency. Smooth surface, but low heating efficiency, suitable for thin sheet forming. [0003] In order to solve the shortcomings of the above-mentioned equipment, it is necessary to make continuous production of crawler roller press to improve production efficiency, so that it can form p...
