Description

The utility model relates to the field of manufacturing products from composite materials.

A known installation for the impregnation of fiberglass containing a roll holder with a brake, an impregnating bath with guide rollers and a pulling device - patent RU No. 2209731 C 2 B 29 C 53/60, 53/56, 29 29 D 23/00 // B 29 K 101: 00, B 29 L 23:00 on "Installation for the manufacture of tubular products from composite material", publ. 08/10/2003

By its characteristics and the achieved result, this installation is closest to the claimed and adopted as a prototype.

The disadvantage of this installation is the low quality of impregnation of fiberglass and its fibers due to the increased moisture content and inefficient drawing of fiberglass through the impregnation bath, which ultimately reduces the quality of composite products made using such fiberglass.

The objective of the utility model is to improve the quality of fiberglass impregnation.

This problem is solved by improving the installation for impregnating fiberglass containing a roll holder with a brake, an impregnating bath with guide rollers and a pulling device.

The improvement lies in the fact that the installation is equipped with a fiberglass heater located between the roll holder with the brake and the impregnation bath, made with an intermediate guide roller located above the bath with the possibility of

regulation of its position relative to the latter; the fiberglass heater is made in the form of a convex plate mounted on a slider mounted in the base rails with the possibility of movement in height.

Providing the installation with a fiberglass heater located between the brake roll holder and the impregnation bath allows the moisture to evaporate from the fiberglass and the micropores of the fiberglass fibers are opened in front of the impregnation bath.

The implementation of the impregnation bath with an intermediate guide roller located above the bath with the possibility of adjusting its position relative to the latter allows in the process of impregnating fiberglass to remove it from the impregnating bath and again into the bath through the intermediate roller with reverse inflection and thereby provide more intensive air removal bubbles from a binder, enveloping fiberglass, better wetting of the fibers and a deeper impregnation of the latter with a binder.

The implementation of the fiberglass heater in the form of a convex plate mounted on a slider mounted in the base rails with the ability to move in height provides a structurally simple contact of the fiberglass with the heater and regulation of the temperature of the fiberglass heating over a wide range by changing the length of the contact by moving the slide with the plate in the base rails with increasing quality cleaning fiberglass before impregnation.

Below, with reference to the attached drawing, describes the proposed installation for the impregnation of fiberglass.

The installation comprises a roll holder 1 with a brake 2, an impregnation bath 3 with guide rollers 4 and 5, a pulling device 6. The installation is characterized in that it is equipped with a heater 7 for fiberglass fabric8, located between the roll holder 1 with a brake 2 and an impregnation

bath 3, made with an intermediate guide roller 9 located above the bath 3 with the possibility of adjusting its position (shown by a dashed line) relative to the latter. The heater 7 of the fiberglass fabric 8 is made in the form of a convex plate, heated by one of the known heat sources, mounted on a slider 10 mounted in the guides 11 of the base 12 with the possibility of movement in height.

When the installation is operating, fiberglass 8 (shown by thin lines) from the roll holder 1 with the brake 2 by the pulling device 6 is sequentially pulled through the heater 7 (which ensures drying of the fiberglass with evaporation of moisture), after which the fiberglass 8 enters the impregnation bath 3 with a binder, envelops the input the guide roller 4, and exits the bath 3 to the intermediate guide roller 9, enveloping which the output roller 5 again goes to the bath 3 (which provides enhanced separation of air bubbles from the binder, improving sma fibers and deeper impregnation of fiberglass). Subsequent repeated pulling of the glass fabric 8 through the bath 3 with the bending of the guide roller 5 finally improves the quality of impregnation of the glass fabric 8.

The device for impregnating fiberglass according to a utility model (due to drying the fiberglass in front of the impregnating bath, better wetting of the fibers and a greater penetration depth of the binder in them) is characterized by an increased quality of impregnation of the fiberglass in comparison with the prototype.
