Description

Bionic high-efficiency stirring glue injection device for aviation carbon fiber multi-dimension Technical Field The invention relates to the technical field of composite material processing, in particular to an aviation carbon fiber multi-dimensional bionic high-efficiency stirring glue injection device. Background In the field of modern high-end manufacturing, the carbon fiber composite material has been one of core materials for promoting the upgrading of key industries such as aerospace, wind power equipment, medical equipment and the like by virtue of excellent mechanical properties and remarkable light weight. For example, in wind power equipment, the large-sized fan blade manufactured by adopting the carbon fiber composite material is lighter in weight, and good toughness and structural strength can be maintained in a strong wind environment, so that the power generation efficiency and the equipment reliability are improved. In the field of medical appliances, the artificial limb and the appliance component prepared from the carbon fiber composite material have the advantages of light weight, high strength, good biocompatibility and the like, and the use experience of patients is obviously improved. However, the preparation process of carbon fiber composites is still limited by the bottleneck of conventional stirring and mixing techniques. Conventional mixers generally rely on mechanical forces (e.g., shear, extrusion, convection) to achieve material mixing, but carbon fibers have physical properties such as light weight, high aspect ratio, and surface inertness, which make it difficult to uniformly disperse the carbon fibers in a matrix. More importantly, the reinforcing effect of the carbon fiber is closely related to the length of the carbon fiber, and the high-strength mechanical action in the traditional stirring process is extremely easy to cause irreversible damage to the fiber, so that the final performance of the composite material is affected. In addition, most of commonly used matrixes (such as epoxy resin, phenolic resin and the like) of the carbon fiber composite material are high-viscosity fluids, the viscosity of the matrix can reach 1000-10000 MPa.s or even higher before solidification, the mixing efficiency of the traditional stirring equipment in a high-viscosity system is low, the energy consumption is high, and stirring dead angles and slurry wall sticking phenomena are easy to form. Aiming at the problems, the prior stirring technology still has obvious defects in the aspects of improving the mixing uniformity, reducing the fiber damage, adapting to high-viscosity media and the like. Therefore, development of a stirring glue injection device capable of realizing multi-dimension, high efficiency and low damage is needed to meet the technological requirements of preparing aviation-grade carbon fiber composite materials. Disclosure of Invention In view of the above, the invention provides an aviation carbon fiber multi-dimensional bionic high-efficiency stirring glue injection device, which aims to solve the technical problems. In order to achieve the above purpose, the present invention adopts the following technical scheme: an aviation carbon fiber multi-dimensional bionic high-efficiency stirring glue injection device, comprising: The frame body comprises a base and a vertical rod fixed on one side of the base, the base is connected with a tank body through a lifting assembly, a cover body is fixed on the top end of the vertical rod, and the lifting assembly is used for controlling the up-and-down motion of the tank body, so that the tank body and the cover body can be opened and closed; A stirring driving motor is fixed on the top surface of the cover body; The stirring device is characterized in that a stirring shaft is connected to a power output shaft of the stirring driving motor, the stirring shaft is inserted into the tank body downwards, a plurality of centrifugal stirring rod assemblies are connected to the stirring shaft, each centrifugal stirring rod assembly comprises an inner rod, an outer rod and a tension spring, the inner rods are fixed to the stirring shaft, the outer rods are slidably sleeved on the outer sides of the inner rods, the tension springs are located in the outer rods and connected between the inner rods and the ends of the outer rods, and a plurality of bionic shell reamers are fixed to the outer rods. According to the technical scheme, the high-efficiency and uniform stirring effect is achieved through the combination of the design of the lifting tank body and the bionic stirring structure, the self-adaptive telescopic characteristic of the centrifugal stirring rod assembly and the layered structure of the bionic shell reamer effectively reduce mechanical damage of carbon fibers in the stirring process, meanwhile, the mixing efficiency and uniformity of high-viscosity slurry are improved, and the overall structure gives consideration to the operation
