Problems solved by technology

In the existing protective film stripping devices, the stripping of the protective film is mostly in the active form, that is, the motor drives the roller to work, and the roller winds the protective film to complete the stripping operation. In this device, since the roller is driven by the motor, the roller speed It is required to match the discharge speed of the prepreg, and the discharge speed of the prepreg depends on the speed of manual operation, so it is difficult to unify the speed of the roller and the speed of manual operation, which will easily cause the protective film to be stripped in advance, resulting in pre-preg after stripping. The accumulation of leaching material brings inconvenience to production

Abstract

The invention provides a carbon fiber prepreg emptying device and emptying method. The emptying device comprises a vertical plate, wherein one side of the vertical plate is rotatably provided with an air swelling shaft in the horizontal direction for mounting a carbon fiber prepreg strip coil; and two support shafts are fixedly arranged beside the air swelling shaft in the horizontal direction, and each support shaft is movably sleeved with a rotary drum assembly. In the design, when a prepreg strip and a roller assembly are tightly attached and pressed, and the strip moves during discharging, the roller assembly is driven to rotate by utilizing friction force between the strip and the roller assembly, and the roller assembly rotates to wind a protective film, so that the protective film and a carbon fiber prepreg layer are separated, automatic stripping of the protective film is achieved, synchronization of stripping operation and prepreg discharging operation is achieved, and smooth production is ensured.

Description

technical field [0001] The invention belongs to the field of aerospace device production, in particular to a carbon fiber prepreg discharging device and a discharging method. Background technique [0002] When aerospace devices use carbon fiber prepreg as the raw material of the part, the operation process is to wind the rolled carbon fiber prepreg tape on the surface of the corresponding mold of the product, and after the winding is completed, the product is demoulded to form a product. The carbon fiber prepreg tape is a three-layer sandwich structure, the middle layer is a carbon fiber prepreg layer, and the inner and outer sides of the carbon fiber prepreg layer are respectively attached with a layer of protective film. Carbon fiber prepreg plies are wound. In the existing protective film stripping devices, the stripping of the protective film is mostly in the active form, that is, the motor drives the roller to work, and the roller winds the protective film to complete ...
