Consumable material pretreatment mechanism applied to 3D printers

Abstract

The invention discloses a consumable material pretreatment mechanism applied to 3D printers. The consumable material pretreatment mechanism comprises a 3D printer shell, a first groove, a second groove, a spring, a transverse adjusting mechanism, a 3D printing head, a feeding cylinder, a stepping motor, a feeding hopper and a servo motor, wherein the 3D printer shell is characterized in that a connecting lug is fixed to the bottom of the side, a movable rod is connected with the inner side of the connecting lug in a manner of sliding up and down, a limiting block is fixed at the top end of the movable rod, a foot pad is fixed to the bottom end of the movable rod, and a limiting groove is formed in the connecting lug. According to the consumable material pretreatment mechanism applied to the 3D printers, a spiral feeding manner is adopted; the defect that continuous feeding cannot be achieved through a piston type pressurization manner is overcome; the production efficiency is improved; only the material body in a heating cylinder is heated instead of heating the whole stored material; the situation that the waste is caused when the molten material body is not used up is avoided; the raw materials are saved; meanwhile, the whole stored material does not need to be heated, so that the heating work can be reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing devices, in particular to a consumable preprocessing mechanism for 3D printers. Background technique [0002] Three-dimensional printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often printed on the mold Manufacturing, industrial design and other fields are used to make models, and are gradually being used for direct manufacturing of some products; [0003] In the prior art: the patent of authorized publication number CN 206633422 U discloses a consumable pretreatment device for 3D printers, which includes a 3D printer shell and a hot-melt crucible. An upper and lower sliding door is installed at the material opening, and a hot-melt crucible is fixedly installed on the other side of the housing of the 3D printer. T...

[0003] In the prior art: the patent of authorized publication number CN 206633422 U discloses a consumable pretreatment device for 3D printers, which includes a 3D printer shell and a hot-melt crucible. An upper and lower sliding door is installed at the material opening, and a hot-melt crucible is fixedly installed on the other side of the housing of the 3D printer. The top of the piston is fixedly connected to the bottom end of the electric telescopic rod, and the top end of the electric telescopic rod is fixed on the pressure sensor mounted on the fixed base, and the fixed base is fixedly mounted on the inner top of the 3D printer shell, and the 3D printer shell There is a PLC controller at the bottom of one side, which requires the piston to protrude from the hot-melt crucible when feeding is required, and then feeds. At this time, the printing work cannot be performed, and it does not have the ability of continuous feeding. In addition, the other It is to heat the material body in the whole hot-melt crucible. If the material body in the hot-melt crucible is not used, the 3D printer stops working at this time, and the material body in the hot-melt crucible will agglomerate after cooling, which cannot be normal use, resulting in wastage of raw materials
