Background

The large composite material wind driven generator blade is formed by combining an upper shell, a lower shell, namely a blade shell, a keel girder and a web plate into a whole by adopting the processes of gluing, hand pasting and the like. The shell root bonding seam is the reference point that the blade punched, in case the bonding seam has the dislocation, can lead to blade root drilling skew, causes the blade to scrap, so require before the bonding to correspond bonding face and mould face parallel. In the blade forming process, the glass fiber cloth layers at the root part are as many as 100 layers, the height of the layers higher than a mold is difficult to control, the thickness of the product after curing is about 100mm, and the end face needs to be polished to be smooth by a polisher. The polishing length is about 1.5m, 2 persons are needed to polish simultaneously by adopting a manual polisher, and the polishing time is long. However, the manual grinding has the defects of high grinding difficulty, poor effect and high labor intensity, a large amount of dust is generated in the grinding process, the environment is influenced, the personal health is harmed, the dust is difficult to clean, and the dust remained on the bonding surface of the product also has great influence on the blade forming quality. At present, no equipment or solution specially designed for the blade root grinding requirement exists at home and abroad. In order to solve the problem, some enterprises adopt a method of trimming and cutting by using tools such as an art knife and the like after glass fiber laying is finished, and polishing after vacuum infusion molding and curing. The method can actually reduce the polishing amount, but the repair and cutting of the glass fiber not only needs thirty minutes of time consumption, but also can cause the disorder and the wrinkle of the fiber of the layer of the blade root, cause the breakage of the glass fiber in the length direction and influence the strength of the root; some enterprises adopt an integral dust collection polisher to polish roots, dust collection equipment is high in value, polishing equipment is high in damage rate, equipment is heavy, labor intensity is high, and improvement of production efficiency is not facilitated; the problems of long polishing time, high difficulty, high labor intensity and large dust generally existing in the prior art are solved.
