The material stirring module includes a fixed frame 1, a stirrer 6, a material storage tank 2, a water storage tank 7, a servo motor A 5 and a telescopic rod 4. The material storage tank 2 is disposed at an upper part of the fixed frame 1 and is connected with the stirrer 6 through a pipeline, the water storage tank 7 is disposed at an upper part of the stirrer 6, and the servo motor A 5 controls the material storage tank 2 through the telescopic rod disposed on the fixed frame 1, so that a material is poured into the stirrer 6. The material storage tank 2 includes a dry material storage tank and an additive storage tank, and the dry material storage tank and the additive storage tank are connected with the stirrer 6 separately. LU102606 The transporting module includes a pumping machine 8, a concrete transporting pipeline 9, a pipeline bracket 10, a 3D printer supporting beam 17, a servo motor B 11, a servo motor C 12 and a beam pipeline bracket 18. The stirrer 6 is connected with the pumping machine 8.
The other end of the pumping machine 8 is connected with the concrete transporting pipeline
9. The 3D printer supporting beam 17 is provided with the beam pipeline bracket 18, the servo motor B11 and the servo motor C 12. The servo motor B 11 controls rising and falling of the concrete transporting pipeline 9; the servo motor C 12 controls movement of the beam pipeline bracket 18. The concrete transporting pipeline 9 is sequentially disposed on the pipeline bracket and the 3D printer supporting beam 17 and is connected with the receiving | and printing module through the beam pipeline bracket 18.
The receiving and printing module includes a 3D printing nozzle 13, a servo D 16, a steering engine 15 and a distance checking disc 14. The concrete transporting pipeline 9 is connected with the 3D printing nozzle 13. The 3D printing nozzle 13 is provided with the steering engine 15 and the servo D 16. The 3D printing nozzle 13 is connected with the distance checking disc 14 through a gear. The distance checking disc 14 is controlled by the steering engine 15 to be engaged with the 3D printing nozzle 13 through the gear for rotation. The servo D 16 controls the interior of the 3D printing nozzle 13 to perform spiral rotation.
The control module 3 is connected with the servo motor A 5, the servo motor B 11, the servo motor C 12, the servo D 16 and the steering engine 15 separately and may employ a computer.
Scales are formed in both the dry material tank and the additive storage tank. The pipeline bracket 10 is a dual-rail pulley trolley. The beam pipeline bracket 18 is an aloft dual-rail pulley trolley.
In the present invention, corresponding scales are formed in both of the dry material tank and the additive storage tank. The required dry material and additive are placed in the dry material storage tank and the additive storage tank respectively, and the water storage tank is filled with the water. A compiled software is opened in an operational system, a button for starting material transportation is clicked, and the servo motor A 5 starts running. The dry material and the additive in the material storage tank 2 are poured into the stirrer 6, and the water with a corresponding proportion is automatically injected into the water storage tank 7 at the same time. After stirring is completed, the concrete material is conveyed into the pumping machine 8 and is transported through the concrete transporting pipeline 9, during 0102606 which as the present invention has a certain distance from a printing field, in order to prevent the concrete transporting pipeline 9 from moving and causing abrasion in transportation of the concrete material, the concrete transporting pipeline 9 is erected on a trolley by applying the 5 pipeline bracket 10 (the dual-rail pulley trolley), and the trolley may move in a rail, on which a 3D building printer runs.
Likewise, in the prior art, when the concrete transporting pipeline 9 is in contact with the 3D printer supporting beam 17, abrasion of the concrete transporting pipeline 9 may be caused due to dragging, so that a schedule is delayed, and a certain economic loss is caused.
In order to solve the problems, in the present invention, if the concrete transporting pipeline 9 on the 3D printer supporting beam 17 needs to be lengthened, the concrete transporting pipeline 9 is hoisted onto the 3D printer supporting beam 17 by the servo motor B 11; and if the concrete transporting pipeline 9 on the 3D printer supporting beam 17 needs to be contracted, the concrete transporting pipeline 9 is hoisted to the position below the 3D printer supporting beam 17 through a small crane composed of the servo motor B 11.
Similarly, in order to prevent abrasion of the concrete transporting pipeline 9, during printing, the 3D printing nozzle 13 may continuously move and then drag the concrete transporting pipeline 9, thus the beam pipeline bracket 18 (a loft dual-rail pulley trolley) is | mounted on the 3D printer supporting beam 17 for dragging the concrete transporting pipeline |
9.
During formal printing, as the 3D printing nozzle 13 may continuously move, the concrete transporting pipeline 9 needs to be continuously dragged. At this time, the operational system is applied to search a current position, and the position and a current movement direction of the 3D printing nozzle 13 are calculated by taking a center point as a base point. Movement of the beam pipeline bracket 18 (a loft dual-rail pulley trolley) is controlled by controlling the servo motor C12 by the operational system, and thus a dynamic balance between the concrete transporting pipeline 9 and the 3D printing nozzle 13 is achieved.
In the printing process, a current graph and an advancing direction thereof are identified and calculated through the control module 3, and the distance checking disc 14 is controlled by the steering engine 15 to be engaged with the 3D printing nozzle 13 through the gear for rotation, so that a photoelectric sensor on the distance checking disc 14 moves parallel to the outer side of a building to be printed, and then a width of the building to be printed is detected.
LU102606 If the width of the building to be printed is too large, the photoelectric sensor transfers this information back to the control module 3, then the servo D 16 is controlled by the control module 3, and then an internal rotation speed of the 3D printing nozzle is regulated to s decrease, so that an ejection amount of the material from the 3D printing nozzle 13 is reduced, and a next water yield of the water storage tank 7 is controlled.
If the width of the building to be printed is too narrow, the photoelectric sensor transfers this information back to the control module 3, and then the servo D 16 is controlled by the control module 3 to control the internal rotation speed of the 3D printing nozzle 13 to rise, so that the ejection amount of the material from the 3D printing nozzle 13 is increased, and the next water yield of the water storage tank 7 is controlled.
In the printing process, the 3D printing nozzle 13 is provided with the detection apparatus that may detect whether the concrete material is sufficient or not may be detected.
A transportation system is started again to transport the material into the 3D printing nozzle 13 if a height of the concrete material descends to a certain degree.
To prevent a detection apparatus from going wrong, a second protection may be set in the control module 3, the demand of the concrete is found within a certain time according to training, and the pumping machine 8 in the material transporting system performs automatic pumping once during printing, so that idling caused by insufficient material may be prevented, and too much material is prevented from being solidified at the same time.
