Description
Technical Field
The invention relates to the field of cement product printing, in particular to a multi-way pipeline joint, a cement spray head device and a cement product 3D printer, which are mainly used for printing cement sculpture.
Background
Three-dimensional printing (i.e., three-dimensional printing) is a technique for constructing objects by layer-by-layer printing using a bondable material such as powdered metal or plastic based on a digital model file. The method is used for manufacturing models in the fields of mould manufacturing, industrial design and the like in the past, and is used for directly manufacturing cement products, such as manufacturing cement sculpture products.
The 3D printer for cement products is a printer for printing cement sculpture products by adopting a three-dimensional printing technology in the prior art, is provided with a spray head for cement printing, and is used for cement printing through the spray head.
However, the existing 3D printer for cement products is often only provided with one spray head for cement printing, i.e. a printing spray head is provided, so that the printing efficiency is relatively low.
It is known that increasing the number of printing heads of a 3D printer for cementitious products can increase the printing efficiency of cement printing to some extent. The number of output channels is increased through the mode of the multi-way pipeline joint, and then the number of printing spray heads is increased through the increased channels, so that the mode of adding the number of spray heads of the cement product 3D printer is provided.
However, in view of the adhesiveness of cement materials, the multi-way pipe joint in the prior art is easy to cause a blockage problem when being used for expanding or adding a spray head of a 3D printer for cement printing of cement products, and once the blockage phenomenon occurs, the existing multi-way pipe joint is inconvenient to dredge blockage on the basis of not dismantling, is inconvenient to use and restricts the progress of cement printing work.
In addition, the existing 3D printers for cement products mostly adopt a constructed frame for printing, namely, the existing 3D printers for cement products mostly need to construct corresponding frames in advance for cement sculpture products to be printed, and the printing spray heads of the existing 3D printers print three-dimensionally based on the constructed frames, so that the use is inconvenient.
In addition, in view of the adhesiveness of cement materials, nozzles of printing nozzles of existing cement product 3D printers are easily blocked, which restricts the printing efficiency of cement product 3D printers to some extent.
In addition, when the existing cement product 3D printer has a printing unsatisfactory position in the cement printing process, an additional mud searching knife is needed to correct the printing unsatisfactory position, so that the printing efficiency of the cement product 3D printer is limited to a certain extent.
This is a disadvantage of the prior art.

Detailed Description
In order to make the technical scheme and advantages of the present invention more clear, the technical scheme of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Embodiment 1:
fig. 1 shows an embodiment of the multi-way pipe joint according to the present invention.
Referring to fig. 1, the multi-way pipe joint 100 in this embodiment includes an input pipe 101 and 4 output pipes, where the 4 output pipes are a first output pipe 108, a second output pipe 109, a third output pipe 110, and a fourth output pipe 111, and one end of the input pipe 101 is respectively communicated with a feed inlet of each of the output pipes. The input pipe 101 is provided with a pipe joint inlet 104 and a mounting portion 105 for mounting the multi-way pipe joint. A filter screen 102 for filtering is fixedly arranged in the input pipeline 101. A filter residue cleaning port 103 is arranged on the side wall of the input pipeline 101, and a cover plate 106 is detachably arranged on the filter residue cleaning port 103; the filter screen 102 and the filter residue cleaning port 103 are both positioned between the pipeline joint inlet 104 and each output pipeline; the filter residue cleaning port 103 is positioned between the pipeline joint inlet 104 and the filter screen 102. It can be seen that the filter screen 102 can filter substances flowing through the pipeline in the input pipeline 101, and filter residues are remained on the filter screen 102; the cover plate 106 can be detached from the filter residue cleaning opening 103, so that filter residues on the filter screen 102 can be cleaned through the filter residue cleaning opening 103, and then the multi-way pipeline joint can be conveniently dredged, and the multi-way pipeline joint can be prevented from being blocked to a certain extent.
Preferably, the pipe joint inlet 104 is arranged on the pipe side wall of the input pipe 101; the mounting portion 105 is a flange, and is sleeved at one end of the input pipeline 101 far away from each output pipeline, so that the mounting is convenient.
Taking the 3D printing field of the multi-way pipeline joint as an example, correspondingly, the substances flowing through the multi-way pipeline joint are cement, and when in use: cement delivered from the outside enters the input pipeline 101 through the pipeline joint inlet 104, and after being filtered by the filter screen 102 in the input pipeline 101, the cement enters the output pipeline respectively. When the filter residue on the filter screen 102 needs to be cleaned, the cover plate 106 is only required to be detached from the filter residue cleaning opening 103, the filter residue on the filter screen 102 can be cleaned through the filter residue cleaning opening 103, and after the filter residue is cleaned, the cover plate 106 detached before is reinstalled on the filter residue cleaning opening 103. Therefore, the multi-way pipe joint disclosed by the invention is convenient to use without disassembling the whole multi-way pipe joint when cleaning filter residues on the filter screen 102.
In conclusion, when the multi-way pipeline joint is applied to cement transportation of a cement product 3D printer, smoothness of cement transportation of the cement product 3D printer is improved, and printing efficiency of the cement product 3D printer is improved subsequently.
It should be noted that, referring to fig. 1, in the multi-way pipe joint of the present embodiment, the top of the input pipe 101 is hollowed out, so that the multi-way pipe joint is convenient to clean after use, and when the multi-way pipe joint of the present invention is used, a user can choose whether to add a sealing cover plate on the top of the input pipe 101 according to actual needs.
Embodiment 2:
fig. 2 shows another embodiment of the multi-way pipe joint according to the present invention.
The difference from the multi-way pipe joint described in embodiment 1 is that the multi-way pipe joint described in this embodiment has a flow sensor 112 installed in the input pipe 101, and the flow sensor 112 is located between the residue cleaning port 103 and the pipe joint inlet 104.
Taking the application of the multi-way pipe joint 100 described in this embodiment 2 in the field of 3D printing of cement products as an example, correspondingly, the substances flowing through the multi-way pipe joint 100 are still cement, when the multi-way pipe joint is used, the flow sensor 112 sends out an alarm signal when the filter residue on the filter screen 102 (i.e. the cement which is not satisfactory) submerges the position where the flow sensor 112 is located, so that a user can clean the filter residue on the filter screen 102 in time, and further ensure the normal filtration of the filter screen 102 of the multi-way pipe joint.
