With the gradual maturity of the building 3D printing technology, the prefabricated building will definitely further improve the building production efficiency and reduce the production cost if the prefabricated building is perfectly combined through 3D printing. Therefore, when the prefabricated building decorative plate is manufactured, a concrete spraying machine is generally used to perform layer-by-layer stacking in a 3D planar printing mode.

[0016] In one of the embodiments of the present application, the horizontal compaction assembly comprises: The double-end screw rod is rotatably connected with the other end of the moving rod through a bearing at the middle part, the other end of the moving rod is fixedly connected with a drive motor, a gear ring is coaxially sleeved outside the double-end screw rod, a gear is coaxially connected with the drive shaft of the drive motor, the gear is engaged with the gear ring, and the drive motor rotates through the drive gear to make the double-end screw rod rotate along the axis thereof; Two threaded sleeves are provided with threads on the inner walls, the two threaded sleeves are sleeved on the two ends of the double-end screw rod and are threadedly connected with the double-end screw rod, the two threaded sleeves are connected with the two cutting wheels through adjusting members, and a strip-shaped sliding groove extending along the length direction of the threaded sleeve is formed in the outer part of the threaded sleeve.

[0020] In one embodiment of the present application, the cutting wheel is a bowl-shaped member, and two bowl-shaped members are arranged oppositely, and the inner walls of the bottom ends of the two cutting wheels are coaxially connected with the connecting shaft.

[0025] By adopting the above scheme, a plurality of steel rings are arranged inside the rubber tube, and adjacent steel rings move away from each other when the rubber tube is stretched. Since the diameter of the rubber tube as a whole decreases when it is stretched, the diameter of the steel ring is not affected. Therefore, when the rubber tube is stretched, a plurality of annular lines are formed on the surface of the steel ring under the resistance of the steel ring, and the annular lines extend along the length direction of the rubber tube. Therefore, when the rotating pressure roller is pressed on the surface of the concrete layer, the roughness of the surface can be changed, thereby enhancing the bonding force between adjacent concrete layers.

[0028] 3. The rotating press roller can be elongated according to the width of the concrete layer when the rotating press roller acts on the surface of the concrete layer and compacts the concrete layer, and at the same time, the surface of the rotating press roller forms a spaced annular pattern during the elongation, so that the surface of the concrete layer can form a spaced strip pattern when the rotating press roller rotates on the surface of the concrete layer, and then the bonding force between the adjacent two concrete layers is improved during the printing and taking of the overlapped concrete layers.

[0040] Please refer to Figure 2The horizontal compacting assembly 31 comprises a double-end screw 311, two threaded sleeves 314, a connecting beam 315 and a rotating roller assembly 316. The middle part of the double-end screw 311 is rotatably connected to the other end of a moving rod 322 through a bearing.

[0044] Please refer to Figure 5 , the cutting wheel 34 is a bowl-shaped member, and two are oppositely arranged, and the inner wall of the bottom end of the two cutting wheels 34 is coaxially connected with the connecting shaft 333. By arranging the bowl-shaped cutting wheel 34, when the edge of the cutting wheel 34 cuts the excess concrete layer, the excess concrete can be discharged from the arc-shaped contour outside the cutting wheel 34, so that the device can quickly direct the slag discharge, and the flatness of the concrete layer will not be affected.

[0045] In the embodiment, the distance between the two cutting wheels 34 is equal to the length of the rotating roller assembly 316, so as to ensure that the rotating roller assembly 316 can cover the width of the concrete layer when the two sides of the concrete layer are cut; In the embodiment, the cutting wheel 34 can be fixed by screwing and connecting with the connecting shaft 333, so as to adapt to different working conditions and disassemble the cutting wheel 34; In order to accurately control the cutting effect, the height of the connecting shaft 333 relative to the bottom rolling plane of the rotating pressure roller assembly 316 is pre-set and fixed. Specifically, the lowest cutting edge of the cutting wheel 34 is flush with the bottom of the rotating pressure roller 3162, or slightly higher than the bottom of the rotating pressure roller (3162). In this way, when the rotating pressure roller 3162 rolls and compacts on the surface of the current concrete layer, the cutting wheel 34 can simultaneously trim and cut the excess concrete slurry squeezed out laterally from the layer, without cutting into the underlying consolidated layer. In addition, the cutting wheel 34 and the connecting shaft 333 can also be adjusted by a gasket to adapt to concrete slurry with different fluidity.

[0046] Please refer to Figure 2 , Figure 5 and Figure 6 , the rotating roller assembly 316 includes a connecting strip 3161 and a rotating pressure roller 3162. The connecting strip 3161 is provided with two ends, and the two connecting strips 3161 are respectively connected and fixed with the outer wall of the two threaded sleeves 314. The rotating pressure roller 3162 is configured to stretch along the length direction of itself. The two ends of the rotating pressure roller 3162 are respectively connected with the two connecting strips 3161. By connecting the two rotating pressure rollers 3162 with the two threaded sleeves 314 respectively, the threaded sleeves 314 can drive the rotating pressure roller 3162 to stretch and contract in the direction of the axis of itself when the threaded sleeves 314 are away from and close to each other, so that the device can adjust the width of compaction according to the width of the concrete slab, and can meet more working condition requirements Please continue to refer to Figure 2 , Figure 5 and Figure 6The rotating pressure roller 3162 comprises a rubber tube 3163 and a blocking block 3165, a plurality of steel rings 3164 are fixedly connected to the inner wall of the rubber tube 3163, the plurality of steel rings 3164 are arranged in sequence along the length direction of the rubber tube 3163, the diameter of the steel ring 3164 is the same as the diameter of the rubber tube 3163 in the natural state, the blocking block 3165 is fixedly assembled at both ends of the rubber tube 3163, one side of the blocking block 3165 is coaxially connected with the connecting strip 3161, a plurality of steel rings 3164 are arranged in the rubber tube 3163, adjacent steel rings 3164 move away from each other when the rubber tube 3163 is stretched, because the diameter of the whole rubber tube 3163 will decrease when the rubber tube 3163 is stretched, and the diameter of the steel ring 3164 will not be affected, so when the rubber tube 3163 is stretched, a plurality of annular lines will be formed on the surface of the rubber tube 3163, so that when the rotating pressure roller 3162 is pressed on the surface of the concrete layer, the roughness of the surface of the concrete layer is increased, and the bonding force between adjacent concrete layers is enhanced.

[0047] In summary, when the device is used for preparing a concrete slab, first, the angle of the spray gun 12 is adjusted as needed, and the concrete sprayer 11 is turned on to spray concrete slurry on the platform. The spray gun 12 is driven by the planar driving assembly 2 to print layer by layer on the platform, and the electric push rod 321 is constantly lifted up and down with the layer-by-layer printing of the concrete. At this time, the rubber tube 3163 can be lifted up with the lifting of the moving rod 322, thereby always being in contact with the uppermost concrete layer and rolling on the surface of the uppermost concrete layer with a certain pressure, thereby improving the bonding force between the concrete layers. When the rubber tube 3163 rolls on the surface of the concrete layer, the driving motor 312 is controlled to rotate, thereby driving the double-headed screw rod 311 to rotate, and the threaded sleeves 314 at both ends of the double-headed screw rod 311 move closer to and farther away from each other, so that the cutting wheel 34 can always move along the edge of the concrete layer with the movement of the planar driving assembly 2, thereby cutting the edge of the concrete layer to make the edge flat.

[0048] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
