Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind ofly vacuumize Dao Zhu mechanism for blade web molding, comprise injecting glue flow-guiding screen 7, spiral overflow pipe 5, Europe rice overflow pipe 3, the gas flow guiding net 6 of two strips, two vacuum unit 8, vacuum bag film and pumped vacuum systems, injecting glue flow-guiding screen 7 is arranged at the upper strata of the glass fabric 2 in mould 1 forming tank, spiral overflow pipe 5 extends from the upper center of injecting glue flow-guiding screen 7 to leaf tip, Europe rice overflow pipe 3 extends from the upper center of injecting glue flow-guiding screen 7 to blade root, two gas flow guiding nets 6 are arranged on two, the left and right object disposing platform of mould 1 along the length direction of mould 1 respectively, two vacuum unit 8 are arranged at the edge, the left and right sides of mould 1 blade root respectively, two vacuum unit 8 lay respectively at the upper end of two gas flow guiding nets 6, two vacuum unit 8 are connected with pumped vacuum systems by pipeline, the left and right sides of mould 1 leaf tip is provided with spiral air-conducting pipe 11, the top of spiral air-conducting pipe 11 is erected on gas flow guiding net 6, the end of spiral air-conducting pipe 11 is connected with pumped vacuum systems by pipeline, the upper center of injecting glue flow-guiding screen 7 is provided with injecting glue seat 4, this injecting glue seat 4 and spiral overflow pipe 5, Europe rice overflow pipe 3 connects, vacuum bag film covers at injecting glue flow-guiding screen 7, spiral overflow pipe 5, Europe rice overflow pipe 3, two gas flow guiding nets 6, two vacuum unit 8, injecting glue seat 4 and the outside of spiral overflow pipe 5 for bleeding, the edge of vacuum bag film is connected by adhesive tape sealing with mould 1 edge.
During work, spiral air-conducting pipe 11, gas flow guiding net 6, vacuum unit 8, vacuum bag film and pumped vacuum systems form a closed pumped vacuum systems, under the effect of negative pressure, resin is made to import glass fabric 2 from the gum-injecting port of injecting glue seat 4 smoothly by Europe rice overflow pipe 3, spiral overflow pipe 5 and injecting glue flow-guiding screen 7, after curing molding, injecting glue flow-guiding screen 7 is torn from blade web and namely completes processing.
In the utility model, because the side near blade root is wider, in injecting glue process, blade root side needs larger glue spillway discharge, therefore adopts the Europe rice overflow pipe 3 that can meet larger spillway discharge demand near the side of web blade root.And due to narrower near the side of leaf tip, in injecting glue process, need glue spillway discharge little, adopt in this side the lower spiral overflow pipe 5 of cost to carry out water conservancy diversion, reduce production cost.Gum-injecting port 4 is arranged in the middle part of web, is connected, which reduces the quantity of gum-injecting port 4, also shorten infusion time with the water conservancy diversion pipe fitting of both sides.
In the course of work, because the amount of resin of root of blade is comparatively large, for preventing resin from entering in the pipeline of pumped vacuum systems, vacuum unit 8 is set herein.As Fig. 2, shown in Fig. 3, vacuum unit 8 comprises one-way ventilating film 12, water conservancy diversion supporting network 13, to bleed seat 15, vacuum bag film 14 and adhesive tape 16, water conservancy diversion supporting network 13 is positioned at the upper strata of one-way ventilating film 12, seat 15 of bleeding is positioned at the upside of water conservancy diversion supporting network 13, vacuum bag film 14 covers at water conservancy diversion supporting network 13, to bleed the upside of seat 15, the edge of vacuum bag film 14 is tightly connected by the upper end-face edge of adhesive tape 16 with one-way ventilating film 12, water conservancy diversion supporting network 13 is positioned at one-way ventilating film 12, in the internal cavities that vacuum bag film 14 and adhesive tape 16 are formed, the bleed middle part of seat 15 is provided with bleeding point.During work, be connected with the bleeding point of seat 15 of bleeding through vacuum bag film 14 by exhaust pipe, exhaust pipe is sealed and matched by the vacuum bag film 14 of adhesive tape and surrounding.One-way ventilating film 12 can only make gas pass through, and resin not by.Water conservancy diversion supporting network 13 has the effect of support and water conservancy diversion, and it can make air inlet face extend to the whole bottom surface of one-way ventilating film 12, and larger air inlet face effectively raises the operating efficiency vacuumized.
As shown in Figure 1, pumped vacuum systems comprises resin trap tank 9 and vavuum pump 10, and the entrance of resin trap tank 9 is connected with spiral air-conducting pipe 11, vacuum unit 8 by pipeline, and the bleeding point of resin trap tank 9 is connected with vavuum pump 10 by pipe fitting.Because the amount of resin of blade tip is less, a small amount of resin in the course of work, is only had to be entered in resin trap tank 9 by pipeline.Vacuum unit 8 is not set herein and can reduces production cost.Certainly, also vacuum unit 8 can be set herein.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
