Description
Technical field
The present invention relates to a kind of thermoplastic continuous fibers composite material 3D printing consumptive material equipment and preparation method thereof, belong to increasing
Material manufacturing technology field.
Background technique
3D printing, also referred to as increasing material manufacturing are successively to increase material by 3D printing equipment according to designed 3D model
To manufacture the technology of three-dimensional objects.Compared with traditional manufacturing technology, 3D printing need not manufacture mold in advance, it is not necessary in manufacturing process
The a large amount of material of middle removal, also can be obtained by final products without going through complicated forging technology, therefore, can be in production
It realizes structure optimization, save material and saves the energy.At present, 3D printing technique is usually used in new product development, quick-acting single and small
Part volume manufacture, the manufacture of complicated shape part, the design of mold and manufacture etc., be also suitable for difficult-to-machine material manufacture,
Configuration design inspection, assembly test and Rapid reverse engineering etc..This high-new manufacturing technology based on material stacking method of 3D printing
Concern more and more extensive both at home and abroad is received, a kind of novel production method will be facilitated, there is vast potential for future development.
Fusion sediment 3D printer (Fused Deposition Modeling) i.e. FDM 3D printer, mechanical structure letter
Single, manufacturing cost and maintenance cost are also minimum, therefore FDM is also most popular 3D printing technique in the world today.3D is beaten
For print machine printer model due to consumptive material and processing method, it is poor to result in the mold strength printed, is not able to satisfy high intensity
The demand of model；In 3D printing technique, at present, the material applied to FDM technique is substantially polymer.Moulding material is general
For ABS, PLA, PA, PC, PVA, PPSF, paraffin etc..The advantages of existing consumptive material is that fusing point is low, easily molded, good toughness, the disadvantage is that by force
Spend low, shrinking percentage is big, is easy warping deformation.
Continuous mineral fibrous material is reinforcing fiber of new generation.The axial strength and modulus of fiber are high, and density is low, compares performance
Height, no creep, thermal expansion coefficient are small.It is to be piled up by mineral fibres such as shaped minerals crystallites along fiber axial direction, warp
Crystallite mineral material obtained from chemical treatment.
The characteristics of thermoplastic continuous fibers composite material is based on the above thermoplastic material and mineral fibres, and one invented
Kind new material, have good composite material comprehensive mechanical property has good processing forming again, is suitable for all FDM skills
The 3D printer of art.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of thermoplastic continuous fibers composite material 3D printing consumptive material
Equipment and preparation method thereof, preferably to promote the comprehensive mechanical property of 3D printing material.
In order to achieve the above object, present invention provide the technical scheme that a kind of thermoplastic continuous fibers composite material 3D
Printing consumables, high-intensity performance essentially consist in two manufacturing process processing methods, one is kinking two fiber filaments one
It rises, by the interaction between two fiber filaments, has the function that improve intensity；The second is polymer melting is wrapped in two
It kinks on fiber filament together, and plays the role of infiltration strengthened.Its high-intensity performance is to pass through melting when 3D printing
Polymer two fiber filaments are sticked together, reached a kind of high strength fibre silk and played main body framework, and polymer
Bonding filling effect is played, to reach high-intensity performance.
The thermoplastic continuous fibers composite material 3D printing consumptive material equipment is the fiber filaments of volume two by rolling wheel two-by-two, will
Two fiber filaments tentatively kink together, and two fiber filaments kinked together are by a root canal road later, above the pipeline beginning
There is molten polymer extrusion device, by extrusion device, molten polymer is coated on two fiber filaments, fiber filament and polymerization
After the silk union of object is by the cooling of one-step cooling system, the novel consumptive material is formed, cooling system exit has one to kink dress
It sets, further two fiber filaments is kinked, finally gained consumptive material is entangled on the coil of wire by traction device.
Above-mentioned traction device kinks device, extrusion device, rolls wheel by control system, coordinated control speed.
Above-mentioned polymer extrusion device is to add material device, motor, control system, heating system by outside and squeeze out dress
It sets and collectively constitutes.Wherein control system is reached by control motor rotation controls polymer extruded velocity, by control heating system
Molten polymer is extruded into pipeline by the viscosity of system control polymer, extrusion device, and cladding speed is omited than fiber hauling speed
Fastly, reach and be coated on fiber filament completely, while fiber filament arrival end, it is more bigger than fiber filament, reach discharge superfluous molten polymerization
The effect of object.
The cooling device is cooled down by liquid, bottom coohng liquid, is driven liquid to recycle in box house by turbine, is melted
Melt the fiber filament of polymer overmold by box house pipeline, reaches uniform cooling effect.
Above-mentioned cooling system controls the control to fluid temperature, thus right by temperature sensor and temperature control system
The fiber filament of molten polymer cladding is uniformly cooled down, and guarantees silk material uniform thickness after cooling.
It is described to kink device, it is to have rubber among a cylinder, has the circular hole more smaller than cooling silk material among rubber, pass through
The extruding of silk material is rotated simultaneously, silk material is driven, kinks two fiber filaments sufficiently, it is strong with skeleton to kink rear fiber filament core
Degree.
The traction device is by one there is the wheel of control revolving speed to coil silk material, kinks device by control and roll
The speed of wheel reaches two fiber filaments and kinks the fiber filament core to be formed with intensity completely.
