Heating assembly for discharging device

Abstract

The invention discloses a heating assembly for a discharging device, and belongs to the field of 3D printing equipment. The heating assembly comprises a barrel body unit, a base unit and a control unit; the barrel body unit is contained in a shell assembly of the discharging device, connected with the inner wall of the shell assembly and used for heating a containing space of the shell assembly; the base unit is contained in the shell assembly of the discharging device and connected with the bottom wall, provided with a discharging hole, of the shell assembly, and is used for heating the containing space of the shell assembly; and the control unit is electrically connected with the barrel body unit and the base unit and used for adjusting the heating temperature of the barrel body unit and the base unit, so that a temperature difference exists between the heating temperature of the barrel body unit and the heating temperature of the base unit. The barrel body unit and the base unit are arranged in the shell assembly, the temperature difference exists between the heating temperature of the barrel body unit and the heating temperature of the base unit through the control unit, the barrel body unit and the base unit can output different heating temperatures at different positions of the shell assembly, and then the discharging speed is guaranteed.

Description

technical field [0001] The invention belongs to the field of 3D printing equipment, in particular to a heating assembly used for a discharge device. Background technique [0002] The 3D printing of existing food materials is to store the food materials in the material tube and open a discharge hole at the bottom of the material tube, and extrude the food material in the material tube from the discharge hole by heating, softening and extrusion. The overall heating temperature of the heating components in the shell component of the discharge device is the same, and most of the food materials are composite materials, and their melting characteristics are also different according to their different compositions. Taking chocolate as an example, during the heating and extrusion process of chocolate, there will be The problem of uneven discharge speed caused by the temperature drop of the chocolate near the discharge hole, therefore, it is necessary to provide a heating assembly ca...
