Description
Technical field
The utility model relates to a kind of print heads for hydrogel 3D cell printing, are suitable for hydrogel 3D cell printing
Machine field.
Background technique
Existing print head is that more simply, operationally had many constant using straight pipe, it is difficult to flow velocity is managed,
In addition it the case where involvement of the load of material and mixing material can not being controlled, being easy to appear blocking printing head, needs
Manually control the problem in print procedure.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and is provided a kind of for hydrogel 3D
The print head of cell printing, it is oriented to the flow direction of hydrogel using helicla flute, so that plastic pipe inner wall is led helically in hydrogel edge
It falls, forms stable and closely knit eddy flow, extend the residence time for leading hydrogel material in plastic pipe, so that hydrogel be made to exist
It is merged more uniformly during printing, prevents from blocking, be conducive to molding.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: one kind being used for hydrogel 3D cell printing
Print head, it includes print head body, the print head body include lead plastic pipe, the inner wall for leading plastic pipe is provided with
For being oriented to the helicla flute of the flowing of hydrogel.
Further, the print head body further includes and the printing head leading plastic pipe and being connected.
Further, the printing head is in coniform, the bottom surface of the printing head and the bottom end phase for leading plastic pipe
Even.
Further, the printing head and the plastic pipe of leading are integrally formed.
Further for auxiliary material is conveniently mixed into, the print head body further includes that at least one is connected with the plastic pipe of leading
Logical subsidiary conduit.
Stablize and closely knit eddy flow further for auxiliary material is formed also, and then uniformly, at the uniform velocity mixed with hydrogel,
The inner wall of the subsidiary conduit is provided with the axially extending helicla flute along the subsidiary conduit.
Further, the subsidiary conduit with described to lead plastic pipe perpendicular.
Further, the internal diameter of the subsidiary conduit is less than the internal diameter for leading plastic pipe.
After above-mentioned technical proposal, the plastic pipe inner wall of leading of the utility model is provided with along its axially extending spiral
Slot, and then hydrogel is oriented to by helicla flute and is leading the flowing in plastic pipe, so that plastic pipe inner wall is led helically in hydrogel edge
It falls, forms stable and closely knit eddy flow, extend the residence time for leading hydrogel in plastic pipe, so that hydrogel be made to print
Process at the uniform velocity, uniform discharge, and merge more uniformly, prevent flash putty, be conducive to molding；The utility model is additionally provided with
At least one is mixed, mixed material is helically conducive to material in print head with the subsidiary conduit leading plastic pipe and being connected
It falls, extends reaction, the incorporation time of material, so that material is sufficiently reacted, mixed, optimize uniformity of mixture, further
It avoids printing head from blocking, improves the success rate of printing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the print head for hydrogel 3D cell printing of the utility model.
Specific embodiment
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model.
As shown in Figure 1, a kind of print head for hydrogel 3D cell printing, it includes print head body, the printing
Head ontology includes leading plastic pipe 1, and the inner wall for leading plastic pipe 1 is provided with the helicla flute of the flowing for being oriented to hydrogel.
As shown in Figure 1, the print head body further includes and the printing head 2 leading plastic pipe 1 and being connected.
As shown in Figure 1, the printing head 2 is in coniform, the bottom surface of the printing head 2 and the plastic pipe 1 of leading
Bottom end is connected.
As shown in Figure 1, the printing head 2 leads the integrated molding of plastic pipe 1 with described.
As shown in Figure 1, be mixed into auxiliary material for convenience, the print head body further includes that at least one with described leads plastic pipe
1 subsidiary conduit 3 being connected.
As shown in Figure 1, in order to enable auxiliary material also formed stablize and closely knit eddy flow, and then uniformly, at the uniform velocity with hydrogel
Mixing, the inner wall of the subsidiary conduit 3 are provided with the axially extending helicla flute along the subsidiary conduit 3.
As shown in Figure 1, the subsidiary conduit 3 with described to lead plastic pipe 1 perpendicular.
As shown in Figure 1, the internal diameter of the subsidiary conduit 3 is less than the internal diameter for leading plastic pipe 1.
The working principle of the utility model is as follows:
1 inner wall of plastic pipe of leading of the utility model is provided with along its axially extending helicla flute, and then is led by helicla flute
Leading the flowing in plastic pipe 1 to hydrogel so that hydrogel helically falls along leading 1 inner wall of plastic pipe, formed stablize and
Closely knit eddy flow extends and leads the residence time of hydrogel in plastic pipe 1, thus make hydrogel printing process at the uniform velocity, uniformly
Discharging, and merge more uniformly, flash putty is prevented, molding is conducive to；The utility model is additionally provided at least one and leads glue
The subsidiary conduit 3 that pipeline 1 is connected, mixes in print head conducive to material, and mixed material is helically fallen, and extends object
The reaction of material, incorporation time optimize uniformity of mixture, further avoid printing head 2 so that material is sufficiently reacted, mixed
Blocking, improves the success rate of printing.
Particular embodiments described above, to the utility model solve the technical issues of, technical scheme and beneficial effects into
