Description
Technical field
The utility model relates to a kind of 3 D-printing head, belongs to three-dimensional printing technology field.
Background technology
Consumer increases day by day for the preference of food moulding, can see and utilize 3D printing technique to realize chocolate etc. moulding to make in prior art.Chocolate 3D printer can be used for the sweets processing class enterprises and individuals families such as cake shop, chocolate factory.
Chocolate 3D printer of the prior art adopts plunger displacement pump to print as printhead usually, in the process printed, along with the chocolate slurries that carry out of time-write interval solidify gradually, the concentration of chocolate slurries changes gradually, thus the dense rare situation of chocolate adopting the chocolate 3D printer of prior art to print can change along with the passing of time-write interval, thus chocolate concentration is uncontrolled at whole print procedure, causes the shortcoming on chocolate mouthfeel and taste.Further, due to chocolate quick solidification, along with thickening gradually of chocolate slurries often there will be serious problem such as printing plug or plunger displacement pump blocking etc. in print procedure.
Summary of the invention
The utility model proposes based on the demand of prior art just, and problem to be solved in the utility model is to provide a kind of chocolate three-dimensional printer, and this three-dimensional printer can the chocolate three-dimensional concentration chocolate in printing of stability contorting.
In order to solve the problem, the technical scheme that the utility model proposes comprises: a kind of 3 D-printing head, and described 3 D-printing head comprises: chamber, plunger, attemperating unit and drive unit; The inner space of described chamber is for holding 3 D-printing material, and the lower nozzle of described chamber is used for discharging 3 D-printing material from described chamber, and described inner space is connected with described nozzle; Described plunger is arranged in described chamber, move by the driving of described drive unit in described chamber 3 D-printing material force thus the 3 D-printing material ordered about in described chamber discharge from described nozzle; Described attemperating unit comprises heating unit, and described heating unit is to the 3 D-printing heating materials in described chamber thus the concentration of 3 D-printing material in described nozzle controlled in predetermined scope.
Adopt such scheme of the present utility model, control the temperature of slurries, the blocking avoiding nozzle makes described 3 D-printing can continuous firing.
Accompanying drawing explanation
Fig. 1 is the overview that the 3 D-printing head of the utility model embodiment is arranged in three-dimensional printer;
Fig. 2 is the overall structure figure of the three-dimensional printer of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described, it is to be noted that this detailed description of the invention is only the citing to the utility model optimal technical scheme, the restriction to the utility model protection domain can not be interpreted as.
Example is shaped to, as Fig. 1 shows the one application of the printhead in the utility model embodiment with chocolate 3 D-printing.It illustrates a kind of 3D printer, comprise frame, printhead 2, travel mechanism 1, print platform 4, servo-actuated cooling unit 3.Printhead of the present utility model is carried out three-dimensional by the travel mechanism's driving in frame mobile, by 3 D-printing moulding material, such as chocolate, is discharged on print platform 4, thus completes printing shaping.
Described printhead comprises chamber 6, plunger 5, nozzle 4, attemperating unit and drive unit.The volume of described chamber is preferably 10ml ~ 60ml; Described chamber comprises inner space, described inner space is for holding chocolate, and described chamber lower portion comprises nozzle 10, and described nozzle is connected with described inner space, for discharging described liquid chocolate from described chamber, the opening diameter of described nozzle is at 0.3mm ~ 1.5mm.Further preferably, be provided with valve between described inner space and described nozzle, described valve opens or closes according to the pressure change in described chamber, thus avoids chamber indoor liquid to reveal voluntarily.Described plunger is arranged in described chamber, can move up and down in described chamber, applies pressure for giving the liquid in described chamber.The bottom of described plunger and the inwall of described chamber fit tightly, and avoid the chocolate in described chamber to reveal from the connecting portion of described plunger and described chamber after bearing pressure.The top of described plunger is connected with drive unit by the force from described drive unit.
Described drive unit comprises stepper motor 7, travelling gear 8 and screw rod, described stepper motor output is provided with gear, the described gear of stepper motor output engages with described travelling gear 8 and drives described travelling gear 8 to rotate, the inside of described vibration gear is provided with and is threaded through described screw thread and coordinates with described screw rod 9, when described travelling gear forward or reverse, described in the screw drive of described travelling gear inside, screw rod does and moves up or down.Drive described plunger upward and downward when described screw motion, thus be embodied as described chamber filling chocolate or discharge chocolate in described chamber.
Have substantive distinguishing features and progressive ground, the plunger displacement pump in the present embodiment comprises attemperating unit, and described attemperating unit comprises heating unit and temperature sensor.Described heater comprises heating film or heating silica gel, and described heating unit contacts with described plunger displacement pump chamber, to inner space and the nozzle heating of described plunger displacement pump, ensures the stability of chocolate concentration of slurry in described chamber.Further preferably, described heating film or described heating silica gel are covered on the shell of described chamber, can carry out the heating of Omnibearing even like this to described plunger displacement pump chamber, thus improve the concentration stabilize printing slurries in described plunger displacement pump further.Described temperature sensor is for measuring the temperature of chocolate slurries in described chamber interior space and described nozzle, described temperature sensor is connected with described heater, according to described temperature sensor senses to temperature control the startup of described heater or closedown thus the temperature of the chocolate slurries of described nozzle controlled in predetermined scope.
Control to ensure that slurries can be printed swimmingly by nozzle by the temperature of said temperature control device, avoid because the change of chocolate concentration of slurry causes the blocking of nozzle, thus affect normally carrying out of printing.In addition because the temperature of described temperature control equipment controls, the uniform composition of Chocalate forming thing is made can to improve chocolate mouthfeel.
The technical solution of the utility model can industrially be applied, thus possesses industrial applicibility.
The utility model is only described with above-described embodiment; the structure of each parts, setting position and connecting all can change to some extent; on the basis of technical solutions of the utility model; all improvement of carrying out individual part according to the utility model principle and equivalents, all should not get rid of outside protection domain of the present utility model.
