Reinforced fabric sewing device and sewing method

Abstract

The invention discloses a reinforced fabric sewing device and a sewing method. The device includes a sewing platform, pressure plates, guide rails and a sewing machine, wherein the upper surface of the sewing platform is a hollow frame; the pressure plates include an upper pressure plate and a lower pressure plate, and a plurality of strips of sewing zones are uniformly arranged on the pressure plates; the guide rails are arranged at the two ends of the sewing platform in the lateral directions; the sewing machine includes a sewing machine stand and a sewing machine head; the sewing machine stand spans across the guide rails longitudinally and is connected with the guide rails in a sliding manner; the sewing machine head is arranged on the sewing machine stand, and can move along the sewing machine stand longitudinally. The frame type sewing platform is arranged and used for laying fabric, the fabric is placed between the upper pressure plate and the lower pressure plate, and the suture line is sutured in the sewing zones of the upper and lower pressure plates, so that the laid center line can be easily calibrated, and the production time of the whole process is reduced; in addition, all layers of reinforced fabric can be pressed tightly, the combination degree among all layers of reinforced fabric is high, and little deformation is caused, therefore, high-performance wind power generation used blade roots can be obtained.

Description

technical field [0001] The invention relates to a reinforced fabric sewing device and a sewing method. Background technique [0002] At present, the roots of conventional wind turbine blades generally need to use 60-100 layers of glass fiber composite fabrics. The conventional method is to prefabricate in sections, such as 20 layers and one section, align the center line of 20 layers of glass fiber composite fabric, simply sew and fix it, and then pour resin to cure; after each section is cured, several sections are poured together with the blades The resin finally takes shape. This preparation method has very high requirements for calibration. Because the glass fiber composite fabric is easy to slide relative to each other, it is very difficult to sew, and only a small amount of sewing can be fixed by pouring resin, so this method takes a long time to lay. Not enough, the degree of bonding between the glass fiber composite fabrics is not enough, it is easy to deform, and ...

This preparation method has very high requirements for calibration. Because the glass fiber composite fabric is easy to slide relative to each other, it is very difficult to sew, and only a small amount of sewing can be fixed by pouring resin, so this method takes a long time to lay. Not enough, the degree of bonding between the glass fiber composite fabrics is not enough, it is easy to deform, and the hardness is limited
