Composite material pre-impregnation rubber belt hot-pressing and lapping device based on rollers

Abstract

The invention designs a composite material pre-impregnation rubber belt hot-pressing and lapping device based on rollers. The composite material pre-impregnation rubber belt hot-pressing and lapping device consists of a base plate, a lower guide roller mechanism, an upper guide roller mechanism, a top plate, two driving mechanisms and a hot air barrel, wherein the lower guide roller mechanism consists of lower guide columns, two lower guide roller frames and a plurality of lower guide rollers; the upper guide roller mechanism consists of upper guide columns, two upper guide roller frames and a plurality of upper guide rollers; a hot air opening is formed in the middle of the top plate; the two driving mechanisms and the hot air barrel are fixedly arranged on the top plate; driving rods of the two driving mechanisms penetrate through the top plate and then are fixedly and respectively connected with the corresponding upper guide roller frames; and the driving mechanisms drive the upper guide roller frames to move along the upper guide columns. The lower guide rollers of the composite material pre-impregnation rubber belt hot-pressing and lapping device are made of polytetrafluoroethylene which has the characteristics of acid / alkaline resistance and resistance to various organic solvents, so that the outer sides of the guide rollers cannot be stuck with adhesives; and when the upper guide rollers and the lower guide rollers are used for extruding rubber belts, the rubber belts can be fully stuck to each other when moving, and air in a stuck part is filtered, so that the quality of a coiled product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of winding and laying molding of composite materials, in particular to a roller-based thermocompression lapping device for composite material prepreg tapes. Background technique [0002] Resin-based composite materials have the characteristics of high specific strength, high specific stiffness, unique designability and good processability, and are widely used in many fields such as aerospace, national defense and civil, among which resin-based composite prepreg tapes are widely used It is used in winding and laying molding process of composite materials. During the winding molding process, thousands of meters of prepreg tape are required to complete a part, and the length of the prepreg tape that can be loaded by the winding equipment is up to 300 meters, so the prepreg tape needs to be continued during the winding process to complete winding process. [0003] At present, the continuation of the prepreg ta...
