Description
Technical Field
The invention relates to the technical field of loose belt raw materials and other composite materials, in particular to an infinite-continuation belt type composite material extrusion forming device.
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 the dipping process, but the uniform distribution of the material is difficult to control, the resin system mainly permeates into the fibers by depending on the tightening pressure of the fiber cloth and the capillary effect of the fiber cloth, so that the tightening speed, the tightening 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 supported on a roller core after excessive resin liquid is 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, the existing loose-thread belt raw materials are mostly formed by filling adhesive among multiple layers of materials and then carrying out compound extrusion, and the existing loose-thread belt raw materials are generally formed by filling adhesive among multiple layers of industrial cloth and then carrying out extrusion forming in the production process, so that a better reinforcing effect can be achieved, and the produced composite material can meet the use requirements of loose-thread belts with different strengths. The loose-thread belt has high requirements on tensile strength and shearing strength of materials removed by the loose-thread belt, if the adopted composite material is uneven in middle bonding filler or thin in thickness, the tensile strength and the shearing strength of the composite material are directly low, so that the service life of the loose-thread belt is shortened, and the specific adaptation equipment of the loose-thread belt is limited.
The technical problem that when the existing belt-type composite material is formed, especially for the composite material with higher requirements on strength and uniformity but relatively lower thickness, the composite material of the type is formed by extrusion is that: the industrial cloth thickness of the raw materials can not be selected, or the industrial cloth with different thickness is selected, various parameters for extrusion forming need to be readjusted or another set of production line equipment needs to be set up, so that the cost is high, the whole processing technology is slow, and the technical problems of serious waste of human resources, high equipment cost and the like in the production of the belt-type composite material with different thickness requirements are solved.
