[0001] The embodiments of the present invention relate to the technical field of building construction, and in particular to a printer head applied to a 3D building printer. Background Art

[0002] 3D printing technology is becoming more and more sophisticated. It can not only print small items, but also be applied to the construction industry. 3D printing is not only a new way of building, but also a subversive way of building. It is more durable, environmentally friendly, efficient and energy-saving. It not only liberates manpower, but also greatly reduces construction costs. The biggest highlight of 3D printing is the reuse of construction waste. At the same time, new buildings will not produce new construction waste, and the air quality in the city will also be improved.

[0003] Since the objects of construction 3D printers are buildings, they are large in size and have relatively simple structural changes. At present, the printer head structure of existing construction 3D printers is relatively simple, mostly with a single discharge pipe. Therefore, when printing wall buildings, the printer head of the construction 3D printer needs to move back and forth along the set track, which not only complicates the construction process but also leads to low work efficiency. Summary of the invention

[0004] To this end, an embodiment of the present invention provides a printer head applied to a 3D architectural printer to solve the problems of complex construction process and low working efficiency of the 3D architectural printer in the prior art.

[0005] In order to achieve the above purpose, the embodiment of the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0030] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1 to 4 As shown, this embodiment provides a printer head for a 3D architectural printer, which includes a bracket 1, a first rotary bearing 21, a fixed frame 3, a material distribution system 4, at least two fixed print heads 5 and an electric rotary table 7. It should be noted that the number of fixed print heads 5 in this embodiment is two, and the number of swing print heads 6 is one.

[0033] like Figure 1 As shown, the bracket 1 is installed on the 3D building printer; the inner ring of the first rotary bearing 21 is fixed to the bracket 1, and the outer ring of the first rotary bearing 21 is driven to rotate by the first rotary motor 22.

[0034] Specifically, the fixing frame 3 and the material distribution system 4 are respectively fixedly connected to the outer ring of the first rotating bearing 21, and the outer ring of the first rotating bearing 21 drives the fixing frame 3 and the material distribution system 4 to rotate. When the first rotating motor 22 drives the outer ring of the first rotating bearing 21 to rotate, the fixing frame 3 and the material distribution system 4 rotate simultaneously.

[0035] More specifically, the two fixed print heads 5 are fixedly mounted on the fixed frame 3, and a swing print head 6 is arranged before the two adjacent fixed print heads 5. The wall printed by the swing print head 6 connects the walls printed by the two fixed print heads 5, which improves the strength and stability of the entire wall.

[0036] In this embodiment, the electric rotating table 7 is fixed to the fixed frame 3, and the swinging print head 6 is fixedly connected to the electric rotating table 7. When the electric rotating table 7 rotates, it drives the swinging print head 6 to swing. The electric rotating table 7 allows the swinging print head 6 to swing back and forth along a set trajectory, which is convenient for increasing the strength and stability of the wall during construction; the fixed print head 5 and the swinging print head 6 are respectively connected to the material distribution system 4, and the material enters the material distribution system 4 and is evenly distributed to the fixed print head 5 and the swinging print head 6. The material distribution system 4 facilitates the transportation of materials to the fixed print head 5 and the swinging print head 6, thereby facilitating the printing work of the fixed print head 5 and the swinging print head 6.

[0037] like Figure 2 As shown, the electric rotating platform 7 includes a platform body 73, a second rotating motor 72 and a second rotating bearing 71. The inner ring of the second rotating bearing 71 is fixed to the fixing frame 3, and the outer ring of the second rotating bearing 71 is fixed to the platform body 73. Therefore, the platform body 73 is fixedly connected to the swing print head 6. The outer ring of the second rotating bearing 71 drives the swing print head 6 to swing under the drive of the second rotating motor 72. It should be noted that the outer ring of the second rotating bearing 71 rotates under the drive of the second rotating motor 72, and drives the platform body 73 to rotate at the same time. The platform body 73 drives the swing print head 6 to swing, which greatly facilitates the swing of the swing print head 6.

[0038] like Figure 3 As shown, the material distribution system 4 is connected to the fixed print head 5 via a hose 8, and the material distribution system 4 is connected to the swing print head 6 via a hose 8. The hose 8 facilitates the delivery of materials to the fixed print head 5 and the swing print head 6 after being distributed by the material distribution system 4.

[0039] like Figure 1 As shown, the printer head used in the 3D building printer also includes a discharge valve 9. Both the fixed print head 5 and the swing print head 6 are provided with a discharge valve 9. The discharge valve 9 is used to control the discharge amount of the fixed print head 5 and the swing print head 6, which greatly facilitates the control of the discharge amount of the fixed print head 5 and the swing print head 6.

[0040] Preferably, an arc-shaped limiting groove 10 is provided on the fixing frame 3, and the swinging print head 6 is installed in the arc-shaped limiting groove 10 and swings along the arc-shaped limiting groove 10. The arc-shaped limiting groove 10 effectively limits the swing of the swinging print head 6, thereby ensuring the stability of the printing work.

[0041] Further preferably, a feed port 401 is provided at the top of the material distribution system 4, and a plurality of discharge ports 402 are provided at the bottom of the material distribution system 4, and each discharge port 402 is connected to the fixed print head 5 or the swing print head 6 through a hose 8, which makes the material distributed by the material distribution system 4 to the fixed print head 5 or the swing print head 6 more uniform.

[0042] like Figure 4 As shown, during the construction of the printer head applied to the 3D building printer provided by the embodiment of the present invention, the fixed print head 5 and the swing print head 6 located between two adjacent fixed print heads 5 are simultaneously printing and constructing, which reduces the number of times the print head moves back and forth, greatly improving the construction efficiency. When a wall with a three-layer structure is used with the printer head, the operation is very simple. The two fixed print heads 5 and the swing print head 6 can complete the printing construction of the three-layer structure wall by moving once along the set track, and the construction is very convenient.

[0043] Example 2

[0044] This embodiment provides another printer head for a 3D architectural printer. The same parts as those in Embodiment 1 will not be described in detail here, and only the different parts will be introduced below.

[0045] Combination Figure 5 The number of fixed print heads 5 is 3, the number of swing print heads 6 is 2, and each swing print head 6 is arranged between adjacent fixed print heads 5, and the swing print heads 6 are arranged one by one with the electric rotating platform 7. The number of print heads is 5, and the printer head can print a wall with a 5-layer structure at the same time, and the printing construction can be completed by moving once according to the designed line, which is very convenient to operate and greatly improves the construction efficiency.

[0046] Preferably, the arc-shaped limit groove 10 is arranged in one-to-one correspondence with the swing print head 6, so that the swing print head 6 can be constructed along the arc-shaped limit groove 10, and the wall printed by the swing print head 6 can also be connected to the wall connected to the fixed print head 5, which further improves the overall stability of the wall.

[0047] The printer head for a 3D building printer provided by an embodiment of the present invention, during construction, a fixed print head 5 and a swing print head 6 located between two adjacent fixed print heads 5 perform printing construction at the same time, which reduces the number of times the print head moves back and forth, greatly improving the construction efficiency. When a wall with a five-layer structure is used with the printer head, the operation is very simple. The three fixed print heads 5 and the two swing print heads 6 move once along the set track to complete the printing construction of the five-layer structure wall, and the construction is very convenient.

[0048] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
