Embodiment Construction

[0040] The present invention will be further described below by means of embodiments and in conjunction with the accompanying drawings.

[0041] Such as Figure 1-2 As shown, the gluing device includes a gluing box 1 and a push rod 2 , and the pushing rod 2 is connected to the gluing box 1 . The gluing box 1 is integrally formed, so that the gluing device has a good overall structure, thereby avoiding long-term use and reducing the quality of gluing. There is no joint structure on the gluing box 1. Therefore, the defect of joint failure or instability caused by the curing of the epoxy structural adhesive in the joint structure in the prior art is avoided, thereby ensuring the stability of the glue after long-term use. quality. The glue box 1 is surrounded by a cavity 11 , the top surface 12 of the glue box 1 is provided with a glue inlet 121 , and the glue inlet 121 communicates with the cavity 11 . The bottom surface of the gluing box 1 is opened to form a bottom opening. ...

Abstract

The invention discloses a glue application device used for coating the surface of a wind turbine blade with glue. The glue application device comprises a glue application box and a push rod. The pushrod is connected to the glue application box which is formed in an integrated manner. The glue application box defines a cavity. The top face of the glue application box is provided with a glue inletcommunicating with the cavity. The bottom face of the glue application box is open and forms a bottom opening. The bottom of the side face of the glue application box is provided with a glue outlet. The glue outlet communicates with the bottom opening. According to the glue application device, the glue application box is formed in an integrated manner, so that the glue application device has a good overall structure, and therefore the situation that after the glue application device is used for a long time, the glue discharge quality is lowered is avoided. Meanwhile, a user can control the height and thickness of the extruded glue through the glue application device and can perform continuous and uniform glue application behavior in a web adhesion area through the push rod, and the glue application efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing megawatt wind power blades, in particular to a gluing device. Background technique [0002] Wind turbine blades are bonded by epoxy structural adhesive to the shells and webs on both sides. The bonding area is the part of the blade with low strength. Therefore, ensuring the bonding quality is of great significance to improving the strength of the blade. [0003] At present, glue is applied manually at the girder of the blade with a glue scraper. This will lead to: 1. The width and thickness of the sizing cannot be effectively controlled during sizing, and the sizing is discontinuous and uneven, and it is easy to cause a lack of glue after the mold is closed; 2. Voids are likely to occur in the bonding area and inside the epoxy structural adhesive. Bubbles, which affect the bonding strength; 3. The slow speed of glue application greatly reduces the efficiency; 4. The amount of glue used is l...
