[0061] The support frame 61 of the pushing component 6 is fixed to the side of the base 1. The inner rotating shaft 63 connects the pushing plate 62 and the worm gear 64. The worm 72 is driven by the double-headed motor 7 to mesh with the worm gear 64, realizing the flipping action of the pushing plate 62. By installing the support plate 74 on the outer side of the rotating rod 71 and installing the support plate 74 and the bottom of the base 1, the stability of the rotation of the rotating rod 71 can be increased when in use.

[0062] The outer side of the rotating rod 71 is fixed to the bottom of the base 1 through the support plate 73, enhancing the stability of the transmission structure.

[0063] The working principle of a 3D printing device for construction provided by the present invention is as follows:

[0064] When the device starts printing, the driving motor 12 is powered on and runs, driving the threaded rod 13 to rotate. Since the threaded rod 13 is threadedly connected to the moving block 14 and the moving block 14 is limited by the sliding groove 11, the moving block 14 will move horizontally along the length direction of the base 1, transporting the placement plate 4 to directly below the printing head 3. At this time, the lifting support frame 21, the horizontal moving component 22, and the vertical moving component 23 in the support component 2 work together to adjust the height and horizontal position of the printing head 3, so that the printing head 3 completes the layer-by-layer printing of the building model according to the preset path;

[0065] After printing is completed, the driving motor 12 rotates in reverse, driving the placement plate 4 to move towards the cutting component 5 at the other end of the base 1. During the movement, the limiting plate 41 slides in the limiting groove 16 to ensure the stable movement of the placement plate 4. And at the same time, the toothed plate 42 on the side of the limiting plate 41 meshes with the gear 53, driving the gear 53 to rotate. The gear 53 drives the guide wheels 52 on both sides to rotate through the rotating rod 51, making the cutting rope 54 sleeved on the guide wheels 52 operate, cutting and separating the connection between the printed part and the placement plate 4;

[0066] When the placement plate 4 completely moves to one end of the base 1, the double-headed motor 7 starts, driving the rotating rods 71 and the worm 72 at both ends to rotate. The worm 72 meshes with the worm gear 64, driving the rotating shaft 63 to rotate, so that the pushing plate 62 flips towards the placement plate 4. When the pushing plate 62 rotates above the placement plate 4;

[0067] At this time, the driving motor 12 rotates forward, thereby driving the placement plate 4 to move towards the top of the base 1. At this time, one side of the pushing plate 62 will contact the side of the printed part, limiting the printed part and pushing the separated model off the placement plate 4 to prevent the model from returning to the printing area with the placement plate 4. The entire process requires no manual intervention, realizing the automated processes of printing, cutting, and unloading.

[0068] Compared with the related technology, a 3D printing device for construction provided by the present invention has the following

[0069] Beneficial effects:

[0070] Through the linkage of the driving motor 12 and the cutting assembly 5, automatic cutting of the printed parts is achieved; the double-headed motor 7 is used to drive the pushing plate 62 to turn over and push the material, replacing the traditional manual picking, reducing the workload of the operator, and improving production efficiency;

[0071] The flexible cutting method of the cutting rope 54 avoids the external force pulling during manual picking, prevents the model from deforming or being damaged due to manual operation, and ensures the structural accuracy and surface quality of the building model;

[0072] Through the coordinated work of mechanical structures such as the driving motor 12, the gear 53, the worm wheel 64 and the worm 72, the whole process automation of "printing - cutting - unloading" is realized, reducing manual intervention and meeting the needs of the construction industry for efficient and standardized model production.

The second embodiment is only the preferred way of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0075] Specifically, the difference of a 3D printing device for construction provided in the second embodiment of the present application is that, for a 3D printing device for construction, a cleaning brush 8 is provided at the bottom of the pushing plate 62.

[0076] A clamping groove 81 is opened at the bottom of the pushing plate 62, a clamping bar 82 is clamped on the inner side surface of the clamping groove 81, a mounting plate 83 is fixedly installed at the bottom of the clamping bar 82, and the mounting plate 83 is fixedly installed on the top of the cleaning brush 8.

[0077] The working principle of a 3D printing device for construction provided by the present invention is as follows:

[0078] During the process of retracting the placing plate 4, the pushing plate 62 will rotate to the top of the placing plate 4, thereby pushing the model thereon to prevent the model from moving to the bottom of the print head 3 along with the placing plate 4; in this way, due to the driving of the pushing plate 62, the cleaning brush 8 will synchronously be located at the top of the placing plate 4, and its bottom abuts against the top surface of the placing plate 4, and the debris on the plate can be cleaned.

[0079] Compared with the related art, a 3D printing device for construction provided by the present invention has the following

[0080] Beneficial effects:

[0081] By setting the cleaning brush 8, while the placement plate 4 is retracted, the debris on the top of the placement plate 4 can be cleaned, avoiding the accumulation of debris on the top of the placement plate 4 and affecting the subsequent printing effect.

[0082] Third Embodiment

[0083] Please refer to Figure 11 , based on a 3D printing device for construction provided in the first embodiment of the present application, another 3D printing device for construction is proposed in the third embodiment of the present application. The third embodiment is only a preferred manner of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0084] Specifically, the difference of a 3D printing device for construction provided in the third embodiment of the present application is that for a 3D printing device for construction, threaded rings 9 are fixedly installed around the bottom of the base 1, and threaded rods 91 are threadedly connected to the bottoms of the threaded rings 9.

[0085] The bottom of the threaded rod 91 is fixedly installed with a backing plate 92.

[0086] The working principle of a 3D printing device for construction provided by the present invention is as follows:

[0087] When in use, the staff can rotate the backing plate 92 to drive the threaded rod 91 to be threadedly connected to the inner side of the threaded ring 9, so as to adjust the height of the backing plate 92 and facilitate the adjustment of the level of the base 1.

[0088] Compared with the related art, a 3D printing device for construction provided by the present invention has the following

[0089] Beneficial effects:

[0090] By the cooperation of structures such as the threaded ring 9, the threaded rod 91, and the backing plate 92, when in use, the level of the base 1 can be adjusted, thus avoiding the base 1 from tilting, resulting in the bottom of the model warping or falling off, and increasing the printing effect of the model.

[0091] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
