Abstract
The invention discloses a fiber stretching device. The device comprises an oven, a heater arranged in the oven, a guide roll, a fiber stretching roll group and a drive unit which is arranged outside the oven and is used for driving the fiber stretching roll group, wherein, the oven is equipped with a fiber bundle inlet and a fiber outlet; the guide roll is arranged at the inner side of the fiber bundle inlet; the fiber stretching roll group is arranged at the inner side of the fiber outlet and comprises drive fiber stretching rolls and driven fiber stretching rolls; the surface of each drive fiber stretching roll is equipped with a circular arc projecting surface; and the driven fiber stretching rolls with smooth surfaces are in a cylindrical shape and are arranged below the drive fiber stretching rolls. By utilizing the fiber stretching device, a glass fiber bundle can be stretched into monofilament fiber with certain width so as to facilitate the impregnation of resin during melt impregnation process.
Description
Technical field
The present invention relates to through the volume field, particularly a kind of fine device of exhibition with the fine one-tenth of fibre bundle exhibition monofilament shape fiber.
Background technology
Glass fibre is a kind of Inorganic Non-metallic Materials of excellent performance, and is of a great variety, and advantage is that good insulating, heat resistance are strong, corrosion resistance good, and mechanical strength is high.It manufactures through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth take glass marble or discarded glass as raw material, the diameter of its monofilament is that several microns are to twenties meters microns, the 1/20-1/5 that is equivalent to a hairline, every bundle fiber precursor are comprised of hundreds of even thousands of monofilament.In the prior art, through compiling thermosets and in compiling thermoplastic processing, needing be the monofilament shape with fibre bundle exhibition fibre first, is convenient to resin impregnated in fiber, prevent from shredded dried bean curd or bubble occurring in the sheet material of moulding, affect the quality of sheet material.But, at present, also do not have the fine device of this exhibition can be with glass fiber bundle according to the monofilament strip material that requires to be launched into one fixed width through compiling textile technology.
Summary of the invention
The object of the invention is to provides a kind of exhibition fine device for lacking in the prior art described in the background technology the problem of glass fiber bundle exhibition fibre for the fine device of exhibition of monofilament strip material.
The technical scheme that can realize goal of the invention of the present invention is as follows:
The fine device of a kind of exhibition, it comprises baking oven, is arranged at the fine roller group of heater, deflector roll, exhibition in the baking oven and is arranged at the outer drive unit that is used for driving the fine roller group of exhibition of baking oven, be provided with fibre bundle entrance and fiber outlet on the described baking oven, it is inboard that deflector roll is arranged at the fibre bundle entrance, open up fine roller group and be arranged at the fiber outlet inboard, the fine roller group of described exhibition comprises initiatively opens up fine roller and the fine roller of driven exhibition, initiatively open up fine roller surface and be provided with the circular arc crowning, the fine roller of driven exhibition is cylindric, its smooth surface, the fine roller of driven exhibition is arranged at the below of initiatively opening up fine roller.
Rotate synchronously in order to make each open up fine roller, guarantee the even tension of fiber, the fine roller group of described exhibition comprises a plurality of fine rollers of initiatively opening up, and all initiatively open up fine roller by same chain-driving, be provided with the pinch roller that prevents the chain play above chain, the wheel pressing shaft of pinch roller is arranged on the pinch roller bearing.
In order to control the fine speed of exhibition, improve the fine effect of exhibition, described drive unit comprise motor, with the reductor that motor output shaft is connected by belt, fine roller is initiatively opened up in the output shaft connection of reductor.
For moisture content contained in sizing material oxide in the fibre bundle and the fibre bundle is got rid of through deflector roll the time, described heater is arranged at the below of deflector roll.
Beneficial effect of the present invention is for carrying out in baking oven because of the fine device of exhibition of the present invention, by heater the air in the baking oven is heated, make it reach the fine required temperature of exhibition, fibre bundle enters in the baking oven outside baking oven, at first arrive deflector roll, because temperature is higher in the baking oven, under the condition of high temperature, remove contained moisture content in the sizing material oxide on fibre bundle surface and the fibre bundle, then, fibre bundle arrives initiatively opens up fine roller, be provided with the circular arc crowning because initiatively open up fine roller surface, fibre bundle can disperse to the both sides of circular arc crowning under the tension force effect, fibre bundle can be scattered, the fine roller of driven exhibition is arranged at the below of initiatively opening up fine roller, the fine roller of driven exhibition is not connected with drive unit, is passive rotation, and the fine roller of driven exhibition is cylindric, its surface is smooth, therefore, eliminated each and initiatively opened up fine roller circular arc crowning peak not in the problem on a plane, made the fibre bundle even tension, strengthened the fine effect of exhibition, each is initiatively opened up fine roller and connects by chain, and pinch roller is set prevents the chain play, makes each open up fine roller and keeps synchronous rotating speed, guarantee the even tension of fiber, prevented yarn fracture when exhibition is fine.
