Extrusion and heating integrated device for chocolate printer

Abstract

The invention relates to an extruding and heating integrated device for a chocolate printer. The extruding and heating integrated device comprises a pneumatic executing mechanism and a slurry extrusion mechanism which are sequentially connected from top to bottom. The chocolate extruding machine is scientific and reasonable in design, the pneumatic executing mechanism controls a variable-diameter pneumatic executing rod to move up and down through ventilation of a first air hole and a second air hole, and starting and stopping of chocolate paste extruding are achieved. A slurry plug of the slurry extrusion mechanism can block slurry at the lower end of a material barrel when the variable-diameter pneumatic executing rod moves upwards, so that the slurry can be instantly sucked back and broken while the slurry is stopped from being extruded from a feeding hole, residual materials on a needle head are reduced, the chocolate slurry does not generate the phenomena of dripping leakage, finedrawing and the like, and the finedrawing and salivation phenomena of the chocolate slurry are effectively relieved. Heating wires and temperature sensors are uniformly distributed in the material barrel and an extrusion head, so that the slurry entering the material barrel and the extrusion head can be quickly and uniformly heated, the rheological property of the chocolate slurry is ensured, and the chocolate slurry is stably and continuously extruded through the extrusion head.

Description

technical field [0001] The invention belongs to the technical field of food 3D printing, and relates to a chocolate printing device, in particular to an extrusion heating integrated device for a chocolate printer. Background technique [0002] At present, 3D printing technology is becoming more and more mature, and has had a significant impact on people's livelihood. The working principle of the 3D chocolate printer is similar to that of the FDM printer. According to the thickness of the slice, it can be printed and superimposed in layers to create a personal chocolate shape. [0003] The extrusion device currently used for chocolate printing is to discharge the chocolate in the container through the nozzle through the gear rotation. The gear rotation method has certain requirements for installation accuracy, and the installation is more complicated and costly. Slurry drawing and other phenomena. [0004] A heating device is used when printing chocolate. Most of the curren...
