Frictioning device suitable for fiber winding equipment

Abstract

The invention discloses a frictioning device suitable for filament winding equipment. The frictioning device comprises a frictioning roller, a servo motor, an encoder, couplers, a motor mounting flange, an encoder mounting flange and bearing seats. The two ends of the frictioning roller are mounted on the bearing seats in a locating mode, and the frictioning roller makes rotating movement relative to the bearing seats at the two ends. The servo motor is connected with one end of the frictioning roller through one coupler and drives the frictioning roller to rotate initiatively. The encoder is connected with the other end of the frictioning roller through the other coupler, and the rotating angle of the frictioning roller is measured in real time. The servo motor and the encoder are fixedly connected with the bearing seats respectively through the motor mounting flange and the encoder mounting flange. The working part of the frictioning roller is a cam with the radius being in linear variation along with the variation of the angle instead of a cylinder body. The motor controls the rotating angle of the frictioning device to control the frictioning distance between the frictioning roller and an impregnation roller, therefore, the thickness of a surface glue layer of the impregnation is controlled. The frictioning device suitable for the fiber winding equipment is simple in structure and convenient and reliable to operate, the frictioning thickness is continuously adjustable, and the precision is high.

Description

technical field [0001] The invention relates to a squeegee device, more particularly, to a squeegee device suitable for fiber winding equipment. Background technique [0002] Filament winding equipment is to make a single bundle or several bundles of continuous fibers impregnated with molten glue through a dipping roller, and then continuously wind them on the roller in a hoop winding manner. It is mainly used to manufacture carbon fiber composite materials. Among them, the amount of glue applied to the carbon fiber by the winding equipment determines the product quality of the final carbon fiber composite material. Different types of products have different glue content requirements, and only the glue content within the corresponding range is a qualified product. In the production process, the rubber dipping roller through which the fiber is dipped into the molten glue is the fiber gluing link. Regulatory control. [0003] The existing squeegee device generally installs a...

Problems solved by technology

The adjustment and control of the distance is realized by the horizontal movement of the scraping blade or the cylindrical scraping wheel on the horizontal plane, and by moving the two ends respectively. This adjustment method has the following disadvantages in the process of use: 1. The adjustment is complicated , it is necessary to constantly fine-tune the two ends to adjust to the required distance; 2. It is easy to cause the outer edge of the scraping film or the axis of the cylindrical scraping wheel to be not parallel to the axis of the dipping roller, that is, the outer edge of the scraping sheet or the cylindrical scraping roller and the dipping roller The roller is prone to deviation in the axial direction, resulting in the thickness of the rubber layer on the outer surface of the dipping roller along the axial direction of the roller is not uniform; 3. A feeler gauge is needed to assist in determining the final distance, and the artificial factor is large and the accuracy is low
