Description
Technical Field
The utility model relates to the technical field of composite material processing equipment, devices, structures and the like, in particular to a composite material processing device for continuous laminating, extruding and bending.
Background
In the existing extrusion forming process of the composite material, two main processes exist: one of the processes is as follows: the material proportion can be well controlled by adopting a spraying process, but the uniform distribution of the materials is difficult to control, a resin system mainly permeates into fibers by depending on the winding pressure of fiber cloth and the capillary effect of the fiber cloth, so that the winding speed, the winding pressure, the kinematic viscosity, the infiltration capacity and the curing speed of the resin system need to be accurately controlled, and the implementation process is difficult due to too much control data.
The uniformity of the two phases can be well controlled by adopting an impregnation process, but the material ratio is difficult to control, and the fiber cloth is impregnated in a resin tank, and then is uniformly wound on a roller core after being extruded by a plurality of groups of rollers. The process is difficult to implement in practice by controlling the resin content by the pair of rollers, and the deviation of the process is often large due to the empirical data control. The resulting composite is also difficult to achieve uniformity of the intermediate binder.
Particularly, in the existing bonding process of multilayer composite materials, especially the raw materials of the loose button belt are formed by filling adhesive in the middle of the multilayer materials and then carrying out compound extrusion, in the production process of the existing loose button belt raw materials, the adhesive is generally filled among the multilayer industrial cloths and then the raw materials are extruded and formed, so that a good reinforcing effect can be achieved, and the produced composite materials can meet the use requirements of the loose button belt with various different strengths.
The existing adjustable buckle belt has higher requirements on tensile strength and shearing strength of materials of the adjustable buckle belt, if the adopted composite material is uneven in middle bonding filler or thinner in thickness, the tensile strength and the shearing strength of the composite material are directly lower, so that the service life of the adjustable buckle belt is shortened, and the specific adaptation equipment of the adjustable buckle belt is limited. In the prior art, chinese patent application CN1709601A, entitled broken line extrusion molding method, discloses that when passing through a broken line channel, the material is subjected to several times of strong shear stress, which has a better effect on the tissue refinement and uniform distribution of the material. However, although the uniformity of the composite material prepared from the folded channel in the length direction near the bending position is good, the uniformity of the composite material in the whole direction needs to be enhanced, and if the composite material is simply subjected to multiple shearing bending, the whole equipment is complex and heavy, and the maintenance and the operation are inconvenient.
The main problems in the prior art are that: the composite material formed by adding the injection material among the multiple layers of materials is required, and during processing, because the bonding filler in the middle of the composite material is uneven or has a thin thickness, the tensile strength and the shearing strength of the composite material are directly lower, so that the service life of the belt-type composite material such as the adjustable belt is shortened, and the specific adaptation equipment of the adjustable belt is limited.
