A 3D printing filament drawing device

Abstract

The invention discloses a 3D printing consumable wiredrawing device. The 3D printing consumable wiredrawing device comprises a wire winding shaft, an extruding machine and a support. A fixed table isarranged on one side of the top of the support. The extruding machine is installed at the top of the fixed table. Supporting plates are both installed at the two ends of the top of the support and further located on one side of the fixed table, and two conveying belts are vertically installed between the two supporting plates. A plurality of guide round roller mounting racks are installed on the conveying belts at equal intervals. Acceding to the 3D printing consumable wiredrawing device, the two conveying belts rotate to drive the multiple round roller mounting racks to move, guide round rollers on the inner sides of the round roller mounting racks rotate to conduct fillet treatment on wires of guide round roller annular grooves, the phenomenon that the cross sections of the wires are ina water drop shape or D shape under the gravity effect of the wires is avoided, the rollers rotate to drive three round roller supports to rotate, rounding rollers on the inner sides of the round roller supports can rotate to conduct rounding treatment on the cross section portions of the wires, the cross sections of the wires are made to be circular, and the quality of the wires is greatly improved. Meanwhile, the rounding rollers and the guide round rollers can rotate, and the friction between the rounding rollers and the guide round rollers with the wires is reduced.

Description

technical field [0001] The invention relates to the field of wire drawing devices for 3D printing consumables, in particular to a wire drawing device for 3D printing consumables. Background technique [0002] 3D Printers (3D Printers) for short (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even give Astronauts print the shape of any desired item, but what 3D prints is the model of the object, not the function of the object. [0003] Additive manufacturing technology (also known as "3D printing") is a method of directly manufacturing three-dimensional physical entities in a layer-by-layer manner based on a computer 3D CAD model. Additive manufacturing technology can quickly and precisely manufacture any complex Shape and structure of parts, so as to achieve "free manufacturing". Compared with traditional processing technology, additive manufacturing can reduce processing costs by more than 20%-40%, a...
