Abstract

The invention relates to a preheating type 3D printing head changing mechanism. The preheating type 3D printing head changing mechanism comprises a printing head, a replaceable printing mechanism anda preheating mechanism; the printing mechanism comprises a printing shell, a discharging nozzle is arranged at one axial end of the printing shell, and an annular concave discharging groove is arranged at a position, corresponding to the discharging nozzle, of the inner wall of the printing shell; the preheating mechanism comprises a preheating shell, a deceleration nozzle is arranged at one axialend of the preheating shell, a preheating head is fixedly arranged at the end part of the deceleration nozzle, and the preheating head comprises a preheating tube made from a heat conduction material; the inner wall, corresponding to the deceleration nozzle, of the preheating shell is provided with an annular preheating sleeve; and the printing head comprises a discharging tube, a feed inlet is arranged at one axial end of the discharging tube, a discharging opening is arranged at the other axial end of the discharging tube, the internal of the discharging tube is connected with a heating ring, a heat conduction rod is fixedly arranged at the middle part of the heating ring through a hollow-out supporting ring, the other axial end of the heat conduction rod is connected with a plurality of scraper plates made from an elastic material through a connecting column, and the peripheries of the scraper plates bend toward the discharging opening of the discharging tube.

Description

technical field [0001] The invention relates to a preheating type 3D printing head changing mechanism, which belongs to the field of 3D printing. Background technique [0002] Because 3D printing generally requires continuous work, the heat resistance requirements for the print head are relatively high when it is continuously working. Traditionally, fans are used to dissipate heat from the 3D print head, but the heat dissipation of the fan can easily lead to local cooling of the printing material, while It will affect the strength and material homogeneity of the test pieces printed later; therefore, our company has designed a device that can preheat and dissipate heat for the 3D printing head in a cycle. Preheating for a period of time is less efficient, so our company has designed a preheating printer head changing mechanism that can compensate for the heat dissipation mechanism.
