Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] as attached figure 1 As shown, a high-stability FRP production device includes a creel 1, a glue tank 2, a forming mold 3 and a traction device 4; the fiber output end of the creel 1 is set correspondingly to the inlet end of the glue tank 2; The outlet end of the glue tank 2 is arranged correspondingly to the inlet end of the forming mold 3; the traction device 4 is arranged on the side of the outlet end of the forming mold 3, and pulls the fibers on the creel 1 to move away from the forming mold 3; the creel 1 After passing through the glue tank 2, the surface of the fiber on the fiber is adhered with resin, and then through the solidification process of the forming mold 3, it is transformed into a solid FRP piece. The production process continues under the action of the traction device 4.

[0031]The glue tank 2 includes a tank body 21 and a transfer cavity ...

Abstract

The invention discloses a high stability glass fiber reinforced plastics production device which comprises a creel, a glue trough, a forming mold and a traction device, wherein an overflow device is matched with a fan to discharge air bubbles on a resin liquid level in the glue trough immediately; the air bubble amount generated when fibers enter the glue trough are reduced through a material guide device; the fibers are prevented from entangling in the glue trough through a roller, so that the skim coating quality is ensured; resins in the glue trough is heated efficiently through a circulator; and the resins are recycled through a transfer cavity. The high stability glass fiber reinforced plastics production device optimizes the impregnating flow fully, so that the defects of a glass fiber reinforced plastics product induced by air bubbles are reduced remarkably, the process stability is improved remarkably, and meanwhile, the resin recycling efficiency is enhanced, and the energy consumption for maintaining constant temperature of the resins is reduced.

Description

technical field [0001] The invention relates to the field of pultrusion molding equipment, in particular to a high-stability FRP production device. Background technique [0002] FRP generally refers to adding unsaturated polyester, epoxy resin and phenolic resin matrix with glass fiber. It is light and hard, with high mechanical strength and strong corrosion resistance. It can replace steel and building materials to manufacture parts or build structures, and has a wide range of uses. There are many ways to manufacture FRP. Among them, the pultrusion process is chosen by the majority of manufacturers because of its characteristics of automatic continuous production, the highest production efficiency and low product cost. [0003] The so-called pultrusion process refers to the processing method that the glass fiber roving or its fabric is finally transformed into a finished FRP product through processes such as dipping, extrusion molding, heating and curing, and cut-to-length...
