Fiberglass pultrusion grille continuous production line

Abstract

The invention relates to a fiberglass pultrusion grille continuous production line which is characterized by comprising a rack, a core mould propulsion mechanism, automatic yarn laying mechanisms, a resin mixture injection mechanism, a heating solidification mechanism, a core mould demoulding mechanism, a grille cutting mechanism and a grille mould composed of fixed mould bodies and a plurality of moving core mould bodies; and the fixed mould bodies of the grille mould comprises a reinforcing fiber imbedding section fixed mould body, a resin mixture injection section fixed mould body and a heat solidification section fixed mould body which can be all matched with the moving core mould bodies in a core mould moving guide channel correspondingly to form a closed grille-shaped mold cavity. The fiberglass pultrusion grille continuous production line has the advantages that pultrusion manufacturing is conducted in a tunnel-type fixed mould cavity; the situations that each grille rib can allow more fibers to be placed in, steeping of matrix resin is more uniform and consistent, and materials are in the process state needed by pultrusion at the time of solidification and forming are guaranteed correspondingly, and accordingly continuous pultrusion production of fiber reinforced plastic is achieved finally.

Description

technical field [0001] The invention relates to a production equipment of glass fiber pultrusion grid, in particular to a continuous production line of glass fiber pultrusion grid. Background technique [0002] Fiberglass grating is a kind of multi-hole plate-shaped material processed with glass fiber as the reinforcing material and resin as the main matrix. It can be widely used in construction, petroleum, chemical industry, electronics, marine exploration and other industries, and has a large application market. [0003] At present, there are three known structures of fiber-reinforced plastic grids, namely molded grids, molded grids and pultruded profile assembled grids. [0004] The molded grid is formed by arranging continuous reinforcing fibers in an open mold and pouring a thermosetting resin and curing under appropriate conditions. Although the reinforcing fibers of the molded grid are continuous fibers, because it is formed by an open single-piece mold, Its fiber c...

Problems solved by technology

[0008] This device can realize the continuous production of FRP grating and improve the production efficiency, but it also has certain defects: the longitudinal fiber laying mechanism, the transverse fiber laying mechanism, the glue injection mechanism, the compacting mechanism and the curing mechanism of the laying mechanism All adopt open structure, the yarn is easy to move out of the grid groove during the yarn laying process, resulting in disordered fiber arrangement, and the good impregnation of the resin cannot be guaranteed during the glue injection and curing, and defects such as uneven impregnation are prone to occur, which greatly affects the The quality of pultruded products, the resin is easy to volatilize into the air, also has a great impact on the working environment, thus affecting the smooth realization and promotion of continuous production of pultruded grids

Therefore, the structure of the mold circulation mechanism is complicated, and when it needs to be recycled again, the mold rack needs to be manually moved to the front inlet side, which makes the mold circulation very inconvenient, which not only increases the labor intensity of the operator, but also reduces the work efficiency.
