Abstract

The invention discloses a cylinder reciprocating extruder for 3D food printing, which comprises a material hopper, a material bin, and a cylinder. One end of the cylinder is connected with a guide tube, and a piston is installed in the cylinder. , a control valve is installed in the material bin, and the control valve is installed coaxially with the material bin and driven by a first motor arranged on the outer side of the material bin to stir the material and transfer the material flow to the cylinder Inside; the piston is connected with a screw rod, and the screw rod is driven by a second motor. In the present invention, by setting a control valve in the material bin, the stirring and mixing effect of the material can be realized, and at the same time, the orderly transfer of the material from the material hopper to the cylinder body can be realized. The whole extrusion process is stable and efficient, and no manual operation is required.

Description

technical field

[0001] The invention relates to the field of 3D printing devices, in particular to the field of food 3D printing equipment and devices, specifically, a cylinder reciprocating extruder for 3D food printing. Background technique

[0002] 3D printing technology appeared in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After being connected to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. This printing technology is called 3D printing technology. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial de...
