Problems solved by technology

[0004] There are many specifications of wind power blades produced in the market. The single-piece molding area of ​​large-scale wind power blades reaches tens of square meters, and the size of a single piece in a certain direction reaches tens of meters. The amount of resin colloid used for infusion is huge. However, the current colloid The perfusion equipment usually has only one perfusion channel connected to the blade, and can only perform single-point perfusion on the blade, resulting in too long perfusion time, which reduces production efficiency, and long perfusion time will cause the first perfused colloid to start to solidify, affecting the perfusion of subsequent colloids. Ultimately reduce the pass rate of the product

Embodiment Construction

[0024] It can be seen from the background art that when the current infusion equipment performs colloid infusion on molds such as blades, only single-point infusion can be used, resulting in too long infusion time.

[0025] figure 1 A schematic structural diagram of an existing perfusion device is shown.

[0026] refer to figure 1 , the perfusion equipment 1 includes: a feeding unit 10 for providing materials; a heating device 20 for receiving the materials provided by the feeding unit 10 for heat treatment; a vacuum defoaming device 30 for receiving the heat-treated materials for degassing Bubble treatment; Cooling device 40, receives the material after defoaming treatment and carries out cooling treatment; Buffer device 50, described buffer device 50 comprises feed port 51 and discharge port 52, and described feed port 51 is connected with cooling device 40, The buffer device 50 receives the cooled material and outputs the material through the outlet 52 .

Abstract

Automatic filling equipment comprises a first defoaming cooling device for material defoaming cooling treatment and a buffering device. The buffering device is provided with a buffering feeding port and at least two buffering discharging ports. The buffering feeding port is connected with the first defoaming cooling device. The buffering device receives materials obtained after defoaming cooling treatment and outputs the materials through the buffering discharging port. The provided automatic filling equipment can output multiple strands of materials at the same time, material flow and pressure can be adjusted, filling can be conducted at the same time, the production efficiency is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of glue injection equipment, in particular to an automatic pouring method. Background technique [0002] Because the vacuum infusion process is less polluting than the traditional process when forming composite materials, it is currently widely used in the production process of wind power blades. The basic principle of the vacuum infusion process is to first lay the fiber layer in the mold according to the design requirements, then vacuum the mold, vacuum the prefabricated sample, and use the vacuum negative pressure to fill the pre-configured resin system with the entire fiber. body. [0003] The vacuum infusion process uses vacuum negative pressure to infuse the resin, and the infusion resin is required to be free of air bubbles, otherwise the existence of air bubbles will cause product defects and seriously affect the mechanical properties of composite components. The resin system used in the vacuum inf...
