Technical field

The present invention relates to a kind of peristaltic pump type 3D and print pen.

Background technology

Along with developing rapidly of 3D printing technique, the application of 3D printing technique in people's daily life is also more and more extensive, 3D prints pen and can conveniently construct the instrument of three-dimensional model and enjoy great popularity as a kind of, it can, for scribble out the threedimensional model of individual character of user, also can cultivate user's space imagining ability; Existing 3D prints pen can only add plastics that hot-extrudable heat melts as raw material by inside, can only be take plastic wire as raw material, and there is following shortcoming in it: useful raw materials is single, and range of application is limited; Raw material extruded velocity is irregular, need to consider heat dissipation problem and has increased the volume of pen, uses dumb.

Summary of the invention

Technical problem to be solved by this invention is to overcome the shortcoming of above prior art: provide a kind of discharging speed evenly the peristaltic pump type 3D of controlled, applied range, the control of the flexible and available 3D printer of use print pen.

Technical solution of the present invention is as follows: a kind of peristaltic pump type 3D prints pen, and it comprises a shell, nib, feed pipe, peristaltic pump, discharge nozzle, incubation cavity, circuit module; Described feed pipe one end is provided with joint, and the other end is connected with the input of peristaltic pump; One end of described discharge nozzle is communicated with described incubation cavity, and the other end is communicated with described wriggling delivery side of pump; Described incubation cavity is communicated with nib; Described peristaltic pump is electrically connected with circuit module.

Described shell is provided with the power interface, data-interface, demonstration and the function key module that are electrically connected with circuit module.

Described circuit module comprises peristaltic pump driver module, power module, data module, control chip module, driver module, key-press module.

As optimization, described peristaltic pump is miniature peristaltic pump, and diameter is 30mm-50mm.

The outlet of described nib is shaped as circle, semicircle, ellipse, polygon, U-shaped, pentalpha, heart, quincunx.

As optimization, described feed pipe, discharge nozzle is hard PP pipe.

The invention has the beneficial effects as follows: the present invention can carry out continuous uniform ground output print raw material (" ink ") by the speed of accurate control miniature peristaltic pump, and print speed is regulation and control easily, feed pipe of the present invention can pass through the feeder sleeve of the external pay-off of joint; The present invention has two kinds of occupation modes: one is that hand-held uses, can be according to the design of scribbling of user's creative thinking; Also peristaltic pump type 3D can be printed to pen and be fixed on the printhead use as 3D printer on 3D printer, and data-interface is connected with computer (host computer), to use drawn 3D model on 3D printer precise Printing computer; The present invention can use raw material type various, be widely used, after being adopted to food grade materials manufacture, feeding conveying parts can be used as the efficient tool that food is interspersed, can adopt that to have the foodstuff that can be melted into modest viscosity slurry characteristics after solid-state, the middle low-temperature heat of normal temperature be raw material, as drawn individualized pattern etc. with chocolate, cream as raw material on birthday cake, also can use liquid ultraviolet curable resin, liquid photosensitive resin is raw material, just can as long as adopt light source to solidify in outside.
