Composite material pultrusion machine

Abstract

The invention relates to a composite material pultrusion forming machine, and belongs to the field of a pultrusion molding device of composite materials, wherein, a traction mechanism consists of a first traction mechanism and a second traction mechanism which have same constructions; a thermoplastic molding die part consists of a first thermoplastic molding die mechanism and a second thermoplastic molding die mechanism; a plastic-dipped part has two plastic grooves which have same constructions; a felt-supplied yarn-passing mechanism has a bracket body which simultaneously corresponds to two pultrusion lines for supplying the glass yarn, the bracket body is provided with a felt pan which supplies the material for the first traction mechanism and a felt pan which supplies the material for the second traction mechanism; a front yarn-passing plate is arranged at the front row position of the bracket body adjacent to the plastic-dipped part, a rear yarn-passing plate is arranged at the rear row position adjacent to the yarn-supplied mechanism. The composite material pultrusion forming machine can effectively save the occupied area of the device, improve the productivity effect of the device, realize the on-line detection and eliminate the slipping phenomenon as the product is pulled and extruded, and ensure the traction effect, cause the glass yarn to gain the pre-stress from the yarn-released step, and effectively increase the intensity of the fiber reinforced plastic profile.

Description

technical field [0001] The invention belongs to the field of pultrusion molding equipment for composite materials, and relates to equipment for thermally molding glass yarn and glass felt into continuous profiles, in particular to a fiberglass pultrusion molding machine with a double-path pultrusion structure. Background technique [0002] In the known FRP pultrusion molding machine, the glass yarn and the glass felt are released freely from the creel and the felt frame respectively by the traction mechanism, so that the glass yarn and the glass felt are dipped in the glue solution through the glue tank, and then passed through the pultrusion tooling frame. The yarn plate and felt sleeve on the upper part enter the mold after pre-forming the mold. The mold is surrounded by the heating sleeve and heated. The glass yarn and glass felt soaked in the glue are solidified and formed through the inner cavity of the mold, and are drawn out by the traction mechanism to form a continuo...

Problems solved by technology

[0007] The known technology is generally in the form of a single unit and a single head, that is, a traction mechanism, an intermediate frame, a thermoplastic molding mold part, a dipping part, a felt feeding mechanism, and a yarn feeding mechanism to form a pultrusion molding system. , so the equipment occupies a large area, it is difficult to reduce the energy consumption of the whole machine, and it is difficult to adapt to the needs of large-scale production
