[0002] In order to ensure that the width of the bonding area of ​​the wind turbine blade web meets the requirements, a bonding area contour line needs to be drawn on the inner side of the web flange. After the line is drawn, it is convenient for employees to operate and conduct subsequent inspections. Usually, a line drawing device is required to draw lines on the bonding area of ​​the wind turbine blade web. For example, a device for drawing lines on the wind turbine blade web with the publication number "CN206383124U" introduces a line drawing device in the web production process. Before the web flange is poured, a horizontal plate body can be placed at the end of the cloth layer of the flange, and a line drawing pen is placed in the pen hole. The horizontal plate body can be pushed to draw the required line on the cloth layer, and the cloth can be cut along the line. Different layers of cloth use pen holes of different heights. The cut cloth layers can achieve the purpose of staggered layers, and can meet the requirements after pouring. No cutting or grinding is required, which makes the operation difficulty of web processing low and the efficiency high. However, the wind turbine blade web line drawing device still has the following disadvantages in actual use:

[0003] When the above mechanism is in use, the thickness of the flange position is uneven, which can easily lead to benchmark errors, and the number of drawing holes is limited, which cannot guarantee that it is completely applicable to various types of wind turbine blades. At the same time, employees draw lines by measuring with a steel ruler and using hand-drawing, so the contour lines drawn have low precision and accuracy, and the drawing efficiency is low.

[0004] Therefore, we proposed a wind turbine blade web bonding area marking device that can solve the above problems well. Utility Model Content
