Half-fluid food 3D printer extrusion system

Abstract

The invention relates to the technical field of 3D printing and in particular relates to a half-fluid food 3D printer extrusion system which comprises a power conveying module, a power conveying module, a pull type conveying module, a temperature control module, a screw rod fixing plate, a motor fixing base and an extrusion system back plate, wherein the upper end of the power conveying module isconnected with the screw rod fixing plate; the lower end of the power conveying module is connected with the motor fixing base; the screw rod fixing plate is fixedly connected with the upper end of the extrusion system back plate; the motor fixing base is fixedly connected with the lower end of the extrusion system back plate; the power conveying module is connected with the pull type conveying module; and the pull type conveying module is connected with the temperature control module. The invention provides the half-fluid food 3D printer extrusion system which is capable of feeding materialscontinuously, precise in temperature control and not liable to cause nozzle blocking phenomena.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a semi-fluid food 3D printer extrusion system. Background technique [0002] The emergence of 3D printing technology not only brings great convenience to the industry, but also brings good news to diners. While keeping the food delicious, it can also bring visual enjoyment to the diners. They can DIY the shape of food by themselves and print them out through 3D printing technology. [0003] At present, there are two types of extrusion systems for food 3D printers: screw extrusion and injection extrusion. Among them, the principle of the screw extrusion type is similar to that of the injection molding machine. The food is conveyed by the threads on the screw, and the screw rotates to compress the food. When the internal pressure increases, the food is extruded from the bottom extrusion head; and the injection extrusion type, as the name implies It is based on the principle ...

AI Technical Summary

Problems solved by technology

[0004] The existing screw extrusion type has relatively high requirements on the material of the screw and the smoothness of the processed surface, which leads to high processing costs, and the screw extrusion type is difficult to accurately control the extrusion volume of the printer, and the cleaning of the remaining material after printing is also very difficult. Trouble; the existing injection extrusion type cannot continuously feed materials, the refueling procedure is complicated, and the material tube needs to be removed for refueling operation, the temperature control accuracy is low, and plugging problems are prone to occur
