the yarn beating device is used for beating yarns on the yarn bed to enable the yarn bed to be flat and uniform in space, so that yarn spreading is realized;

the yarn beating device comprises a chain capable of being driven, a plurality of copper sheets are fixed on the chain, the chain is perpendicular to the advancing direction of the yarn bed, and the lower ends of the copper sheets are in contact with the yarn bed.

2. The apparatus for reducing flashing of a bed of glass fiber yarn of claim 1 wherein: the copper sheets are evenly distributed on the chain at intervals.

3. A method for reducing the overlap of a glass fiber yarn bed is characterized in that: the method comprises the steps of firstly, using a bobbin creel to pay off yarns, enabling the glass fiber yarns to be arranged into a yarn bed along a drying channel of a tunnel type drying oven, then using the tunnel type drying oven to preheat the yarn bed, enabling a sizing agent on the surface of the yarn bed to be loose, and then stirring the glass fiber yarns of the yarn bed by using a copper sheet of a yarn beating device on the preheated yarn bed to enable the glass fiber yarns to be uniformly distributed and flattened.

The technical field is as follows:

the invention relates to the field of new materials, in particular to a device and a method for reducing the flash of a glass fiber yarn bed.

Background art:

the existing production line of the continuous glass fiber reinforced thermoplastic composite material mainly comprises a bobbin creel and a yarn spreading roller, namely, glass fibers enter a tension roller from the bobbin creel through a guide roller, the spreading effect of a glass fiber yarn bed is adjusted by changing the number of the tension rollers, and the method can achieve the spreading effect of the glass fiber yarn bed only by needing larger tension. Not only influences the surface quality of the glass fiber and has obvious flash phenomenon, but also is easy to have broken yarn.

The invention content is as follows:

the invention aims to solve the technical problem of providing a device for reducing the overlap of a glass fiber yarn bed, which can greatly improve the yarn spreading effect and reduce the damage of the yarn bed.

The technical scheme of the invention is to provide a device for reducing the flash of a glass fiber yarn bed, which comprises

The bobbin creel is used for releasing yarn;

the tunnel type drying oven is used for guiding the glass fiber yarns discharged from the bobbin creel into the tunnel type drying oven, preheating the glass fiber yarns after the glass fiber yarns are arranged into a yarn bed, and loosening the sizing agent carried on the surfaces of the glass fiber yarns;

the yarn beating device is used for beating yarns on the yarn bed to enable the yarn bed to be flat and uniform in space, so that yarn spreading is realized;

the yarn beating device comprises a chain capable of being driven, the chain is wound on a driving wheel and a driven wheel, the driving wheel is driven by a motor, a plurality of copper sheets are fixed on the chain, the chain is perpendicular to the advancing direction of a yarn bed, and the lower ends of the copper sheets are in contact with the yarn bed.

Preferably, the copper sheets are uniformly distributed on the chain at intervals.

The invention also provides a method for reducing the overlap of the glass fiber yarn bed, which comprises the steps of firstly utilizing a bobbin creel to discharge yarns, arranging the glass fiber yarns into the yarn bed along a drying channel of a tunnel type drying oven, then utilizing the tunnel type drying oven to preheat the yarn bed, loosening a sizing agent on the surface of the yarn bed, and then utilizing a copper sheet of a yarn beating device to stir the glass fiber yarns of the yarn bed on the preheated yarn bed discharged from the tunnel type drying oven, so that the glass fiber yarns are uniformly distributed and are flattened.

Compared with the prior art, the invention has the following advantages after adopting the scheme: the bobbin creel and the yarn spreading are separated through the tunnel type drying oven, so that the glass fiber yarns are beaten by the copper sheet of the yarn beating device after being preheated, the glass fiber yarns are uniformly distributed in the yarn bed, the yarn spreading effect is greatly improved, and the damage of the yarn bed is reduced.
