Problems solved by technology

[0003] 1) The connection between the stepper motor, the conveyor belt and the screw rod adopts a locking tooth structure, because the locking tooth structure is prone to slippage during the printing process, resulting in printing failure;
[0004] 2) Each time, the printing nozzle can only be controlled to move with the unit step displacement corresponding to the stepping motor, and the position of the printing nozzle cannot be accurately positioned, resulting in poor imaging quality of the printed product, rough surface and strong graininess;
[0005] 3) Only the print nozzle can be moved horizontally or vertically, and the angle of the print nozzle cannot be controlled

Abstract

The invention discloses a step mechanism for a fused deposition type 3D printer. The step mechanism comprises a horizontal module, a first perpendicular module, a second perpendicular module, a first width module and a second width module, wherein a horizontal guide rail, a first guide rail and a second guide rail are arranged on the horizontal module, the first perpendicular module and the second perpendicular module respectively, the first guide rail and the second guide rail are arranged in the vertical direction; a printing spray head is arranged on the horizontal guide rail; an angle regulating connecting plate with a cavity structure is arranged on the first guide rail; a rotary connecting plate with a through hole is arranged on the second guide rail; a shaft perpendicular to the first guide rail is further arranged on the first guide rail; a rotary shaft perpendicular to the second guide rail is further arranged on the second guide rail; the shaft penetrates through the cavity structure and then is connected with one end of the horizontal module; the rotary shaft penetrates through the through hole and then is connected with the other end of the horizontal module; a first control module, a second control module, a third control module and a fourth control module are arranged on the first perpendicular module, the second perpendicular module, the first width module and the second width module respectively.

Description

technical field [0001] The present application relates to the field of printers, in particular to the field of 3D printers, and in particular to the stepping mechanism of fused deposition 3D printers. Background technique [0002] The Fused Deposition Modeling (FDM, Fused Deposition Modeling) 3D printer is a widely used 3D printer. The working principle of the fused deposition 3D printer is to rely on the stepping mechanism of the printer to control the movement of the printing nozzle that sprays the printing material and the movement of the tray carrying the printing material to perform 3D printing. In the known technology, the stepping mechanism of the fused deposition 3D printer includes a conveyor belt, a screw rod, a tray, a stepping motor, and a printing nozzle, wherein the conveyor belt, the screw rod, and the tray are all connected to the stepping motor through a locking mechanism. The working principle of the stepping mechanism is: the stepping motor drives the con...
