Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] When pouring the blades, the tip pouring system is usually connected to the blade body. Once the blade body pipeline is opened during the pouring process, it is difficult to control the glue flow direction and the flow rate of the blade tip, resulting in a slow gluing speed in the local area of ​​the blade tip, and prone to subsequent defects such as resin overflow, pouring whitening and local dry yarn. The repair process of these defects will affect the overall molding speed of the blade, and at the same time will affect the blade molding quality.

[0036] For this reason, Figure 1 As shown, the embodiment of the present application discloses an auxiliary tool for infusing blades, including a control component 100. The control component 100 can completely disconnect the pre-bending start position of the blade tip side from the infusing device of the blade shell, and at the same time realize the controllability of the injection process of the tip part with a larger pre-bending of the blade, thereby effectively eliminating defects such as excess resin in the blade tip layer and whitening during infusion, reducing the repair process, and improving the efficiency of blade molding while ensuring the quality of blade molding.

[0039] Exemplarily, the control valve 101 may include a liquid inlet port and a liquid outlet port. For ease of understanding, the connecting pipe 102 connected to the liquid inlet port of the control valve 101 is defined as the liquid inlet pipe, and the connecting pipe 102 connected to the liquid outlet port of the control valve 101 is defined as the liquid outlet pipe. The liquid inlet pipe is connected to the infusion device of the blade shell through the first infusion pipe 103, and the liquid outlet pipe is connected to the infusion device of the blade tip through the second infusion pipe 104, so that the resin glue can be infused into the blade tip by the infusion device of the blade shell through the control component 100, so that the flow rate and flow rate of the resin glue infused into the blade tip can be adjusted by the control valve 101, thereby effectively eliminating defects such as excess resin in the blade tip layer and whitening due to infusion, reducing the repair process, improving the quality of blade molding, optimizing the overall moment of the blade, and improving the efficiency of blade molding.

[0040] In the above embodiment, the control valve 101 and the connecting pipe 102 can adopt a split structure or an integrated structure, and the control valve 101 can be made of metal materials such as iron and copper, or plastic, and the connecting pipe 102 can be a plastic pipe or a metal pipe.

Of course, the control valve 101 may also be a reusable metal butterfly valve or ball valve, and the connecting pipe 102 may be a PVC (Polyvinyl Chloride) pipe, and may be connected to the two ports of the control valve 101. In addition, the first perfusion pipe 103 and the second perfusion pipe 104 may be steel hoses, which may improve the strength of the perfusion pipes while ensuring their flexibility.

[0042] In the above embodiment, in order to ensure the sealing of the connection of the connecting pipe 102, sealing strips can be respectively placed around the connection ports at both ends of the connecting pipe 102 to ensure the sealing of the connection between the connecting pipe 102 and the control valve 101 and the perfusion pipe. Of course, sealing gaskets can also be set at the connection position or sealants can be applied to seal.

[0043] The auxiliary tool for infusing blades disclosed in the embodiment of the present application is connected to the infusion equipment of the blade shell through the first infusion pipe 103 through one of the connecting pipes 102 connected to the two ports of the control valve 101, and the other is connected to the infusion equipment of the blade tip through the second infusion pipe 104, so that the starting position of the pre-bending of the tip side of the blade can be completely disconnected from the infusion equipment of the blade shell, and the injection process of the tip part of the blade with a larger pre-bend can be controllable through the control valve 101, which can effectively eliminate defects such as excess resin in the tip ply and whitening during infusion, reduce the repair process, improve the blade molding quality, optimize the overall torque of the blade, and improve the blade molding efficiency.

[0044] The auxiliary tool for infusing blades disclosed in the embodiment of the present application can completely disconnect the starting position of the pre-bending of the tip side of the blade from the infusion equipment of the blade shell, and at the same time realize the controllable injection process of the tip part of the blade with a larger pre-bend, thereby effectively eliminating defects such as excess resin in the tip layer and whitening due to infusion, reducing the repair process, and improving the blade molding efficiency while ensuring the blade molding quality.

[0045] The embodiment of the present application also discloses a perfusion system, including a perfusion device for perfusing blades and an auxiliary tool for perfusing blades disclosed in the above embodiment, so the perfusion system has all the technical effects of the above auxiliary tool, which will not be described in detail herein. It should be noted that the perfusion device for perfusing blades may include a perfusion device for perfusing blade shells and a perfusion device for perfusing blade tips.

[0046] like Figure 2 As shown, an embodiment of the present application also discloses a blade infusion method, which adopts the infusion system disclosed in the above embodiment. Therefore, the blade infusion method has all the technical effects of the above-mentioned infusion system, which will not be repeated here. The blade infusion method includes step S100 connecting the control valve, step S101 cutting the infusion pipe, step S102 installing the control component and step S103 infusing resin glue.

[0047] Step S100, connecting a control valve;

[0048] The two pre-cut connecting pipes 102 are respectively connected to the control valve 101. Specifically, the two pre-cut PVC pipes are respectively connected to the two ports of the control valve 101.

[0049] Step S101, cutting the perfusion tube;

[0050] Cut the first perfusion tube 103 and the second perfusion tube 104 to target lengths. Specifically, cut two sections of steel hose according to actual size requirements on site, and use them as the first perfusion tube 103 and the second perfusion tube 104, respectively.

[0051] Step S102, installing the control component;

[0052] One end of the first perfusion pipe 103 is connected to one of the two connecting pipes 102, and the other end of the first perfusion pipe 103 is connected to the perfusion equipment of the blade shell, one end of the second perfusion pipe 104 is connected to the other of the two connecting pipes 102, and the other end of the second perfusion pipe 104 is connected to the perfusion equipment of the blade tip.

[0053] Step S103, pouring resin glue;

[0054] The infusion equipment of the blade shell and the infusion equipment of the blade tip are turned on, and the infusion parameters of the resin glue are controlled by adjusting the control valve 101 until the blade infusion is completed. The infusion parameters may include the flow rate and flow rate of the resin glue. By controlling the flow rate and flow rate of the resin glue, the occurrence of defects such as excess resin in the blade tip layer and infusion whitening can be eliminated, the occurrence of infusion defects on the blade tip side can be reduced, the blade quality can be improved, and the defect repair time cycle can be reduced, thereby reducing the entire blade molding cycle and improving the blade molding efficiency.

[0055] In the above step S100 of connecting the control valve, in order to ensure the sealing of the connecting pipe 102, a step of winding a sealing strip is also included, by winding 2 to 3 layers of sealing strips on the outside of the two connecting ports of the connecting pipe 102 respectively, so as to ensure the sealing effect of the connecting ports. Of course, other sealing methods can also be used, and the specific other sealing methods have been described above, and will not be repeated here.

[0056] It should be noted that the step S100 of connecting the control valve and the step S101 of cutting the infusion tube can be prepared in advance before the blade is produced, thereby reducing the molding cycle of the entire blade.
