It is overlapped with the axis of the discharge port 12 of hopper 1, in this manner it is ensured that the gap etc. between discharge port 12 and fibre bundle outlet 32
Width, so that 3D printing slurry 2 can uniformly wrap up flexible fiber beam 4.
Electric rotating machine 5 is mounted on the top of hopper 1, and electric rotating machine 5 can be fixed on to the mounting bracket for setting up hopper 1
On.5 driving coupling of electric rotating machine is in cored screw bar 3, for driving cored screw bar 3 to rotate in a circumferential direction around own axes,
The output shaft 51 of electric rotating machine 5 is connected in cored screw bar 3 by a gear drive, which is existing skill
Art is made of a driving gear 52 and a driven gear 34, and the central coaxial of the driving gear 52 is arranged and is fixed on electric rotating
On the output shaft 51 of machine 5, the central coaxial of the driven gear 52 is arranged and is fixed on the upper end outer wall of cored screw bar 3, actively
Gear 52 and driven gear 34 are intermeshed, the startup of electric rotating machine 5, drive gear mechanism action, drive cored screw bar 3 around
Own axes realization rotates in a circumferential direction, and then utilizes the conveying 3D printing downwards of spiral structure 33 with 3 outside week of cored screw bar
Slurry 2.Wherein, flight or helical tooth type water pressing structure etc., and the spiral structure can be used in the spiral structure 33 outside cored screw bar 3
33 hand of spiral is made toward the direction of the discharge port 12 of hopper 1.
Discharge outlet 14 is equipped at the discharge port 12 of hopper 1, discharge outlet 14 is equipped with controlled valve, and discharge outlet 4 is for expecting
When bucket 1 carries out internal washing, as the outlet of clean water, controlled valve is set thereon, when hopper 1 conveys slurry, is closed
Controlled valve prevents slurry from being flowed out from discharge outlet 14, when discharging ejected wash water, turns on the switch valve, excludes clear inside hopper
Clean water.
Further, the discharge port 12 of hopper 1 is formed with a fusion section 13, and the effect that this section merges section 13 is to be used for
3D printing slurry 2 and flexible fiber beam 4 are merged, when flexible fiber beam 4 passes through the cavity 30 inside cored screw bar 3 to come the section
It merges in section 13, touches external 3D printing slurry 2, it can be due to the sticky nature of of 3D printing slurry 2 itself, by 3D printing
Slurry 2 wraps, and is carried over hopper 1 with the downward trickling of 3D printing slurry 2, and the discharge port 12 of extrusion hopper 1 constitutes
The sandwich complex building 3D printing material of the present invention.
As the better embodiment of the present invention, as shown in Figure 1, the sandwich complex building 3D printing material of the embodiment of the present invention
The preparation facilities of material further includes pumping equipment 6 and output equipment 7.
Sand conveying equipment with pump can be used in the pumping equipment 6, for pumping 3D printing slurry 2, is connected on the pumping equipment 6
The other end of pump line 61, pump line 61 is connected to the feeding mouth 11 of hopper 1, due to will be in 3D printing slurry 2 pump line to hopper 1
Portion realizes feed.
Hoist engine can be used in the preparation facilities 7, and for putting and providing flexible fiber beam 4, which can with one
The shaft 71 of rotation, the coiling of flexible fiber beam 4 are formed discoid in the shaft 71.
The present invention constitutes completely new print head with hopper and the combination of cored screw bar, due to printing sandwich complex building 3D
Printed material, flexible fiber beam are passed through from the hollow shaft core portion of cored screw bar, and 3D printing slurry is added from hopper, cored screw
Bar rotates, and using its external spiral structure, the 3D printing slurry in hopper is squeezed out, while extrusion, flexible fiber beam quilt
3D printing slurry uniformly wraps up, and since flexible fiber beam is using flexible fibers such as glass fibre, carbon fibers, disclosure satisfy that 3D
The walking demand of pahtfinder hard is printed, and then meets the distributed steel requirement of 3D printing building.Meanwhile it can be by flexible fiber beam according to length
Direction oriented arrangement is spent, makes the direction in space of fiber along most useful for the directional spreding for improving tensile strength, the enhancing of fiber is imitated
It should maximize.
With reference to the Preparation equipment in above-described embodiment, to the sandwich complex building 3D printing material of the embodiment of the present invention
Preparation method, be described in detail.
Still coordinate shown in Fig. 1 and Fig. 2, the preparation method of the present embodiment is using the sandwich complex building in above-described embodiment
The preparation facilities of 3D printing material carries out, which mainly includes the following steps：
Step 101 provides flexible fiber beam 4, and flexible fiber beam 4 is penetrated from the fiber beam entrance 31 of cored screw bar 3
Internal cavity 30, and flexible fiber beam 4 is made to be moved to the direction of fibre bundle outlet 32 along cavity 30, wherein flexible fiber beam 4
It is fed by output equipment 7；
Step 102 provides the hopper 1 that accommodated inside has 3D printing slurry 2, wherein 3D printing slurry 2 is by pumping equipment 6
Feed；
Step 103, the discharge port 12 for opening hopper 1 simultaneously start electric rotating machine 5, and the output shaft 51 of electric rotating machine 5 rotates, and drives
Moving gear mechanism drives cored screw bar 3 to rotate in a circumferential direction movement, the effect of the spiral structure 33 outside cored screw bar 3
Under, the 3D printing slurry 2 inside hopper 1 is subjected to rotation conveying to the direction of its discharge port 12；And
Step 104, when the lower end of flexible fiber beam 4 be moved to cored screw bar 3 fibre bundle outlet 32, hopper 1 goes out
3D printing slurry 2 at material mouth 12 forms sandwich complex building 3D printing since intrinsic viscosity firmly wraps flexible fiber beam 4
Material, and discharge port 12 is exported downwards, carry out 3D printing.
The present invention proposes a hollow, exterior arrangement flight in middle part or the cored screw bar of helical tooth type water pressing structure, in
Portion's cavity is for transmitting flexible fiber beam, and the raw material of the flexible fiber beam are at flexible fiber Shu An discoid, which is justified
Loaded on elevator arbor, by hoist engine slow release flexible fiber beam, its feeding is realized, the feeding speed and printing cephalic par
The cement mortar discharging speed of discharge port is consistent.
On the one hand the cored screw bar completes printing equipment end convolution and conveys cement mortar, realize the extrusion of constant speed quantitative
Formula discharges (being controlled with the spin rotary speed of cored screw bar)；Meanwhile penetrating flexibility in cored screw bar center cavity
Fibre bundle, realization cement mortar and flexible fiber beam discharge simultaneously, and (flexible fiber beam is wrapped in cement mortar, and the two synchronizes defeated
Go out), using the sticky nature of cement mortar itself, form the composite reinforced building 3D printing that a kind of inside is wrapped with reinforcement " muscle "
With cement mortar, high tensile, the high shear strength of building 3D printing component and building are realized.
