Multi-pipeline pump driving type fiber impregnation system

Abstract

The invention relates to a fiber impregnation system. The fiber impregnation system comprises a fiber impregnation box (110) and a driving pump (120) connected with the fiber impregnation box (110) by one or more refluxing hoses (122), wherein the refluxing hoses (122-1, 122-2 and 122-3) are used for recycling resin from the fiber impregnation box and refilling the fiber impregnation box with the resin under the driving action of the driving pump; and preferentially, the driving pump (120) is a peristaltic pump or a diaphragm pump. Besides, the invention also relates to equipment for performing pultrusion on fibers (100) to obtain a section material (200) by use of the fiber impregnation box. According to the fiber impregnation system, the fiber impregnation box and the peristaltic pump provided with at least one pump head are combined, and the quantity of pumps, pump heads and pipelines is increased as required by production and processing, thus, the fiber impregnation box is not required to be closely connected with a corresponding molding and solidifying device, and a yarn guiding plate can be arranged in the fiber impregnation box; and the fiber impregnation box and the corresponding molding and solidifying device can be separable and vacuumizing operation is carried out, and thus, the fiber exhaust efficiency is improved.

Description

technical field

[0001] The invention relates to a general-purpose fiber impregnation system used in a pultrusion molding process, in particular to a multi-pipeline pump-driven fiber impregnation system. The fiber impregnation system is suitable for application in the field of pultrusion molding, more specifically, it is suitable for application in the field of pultrusion molding of polyurethane resin. On the other hand, the present invention also relates to a device for pultruding composite materials using a multi-pipeline pump-driven fiber impregnation system. Background technique

[0002] With the continuous expansion of the application field of pultruded products, the specifications and varieties of pultruded products are also increasing. In addition to standard pultruded product shapes such as L-shaped, O-shaped, U-shaped, flat-shaped, hollow or solid, various special-shaped structures can also be produced according to customer needs. The size of the pultruded composit...
