Description

Technical Field

[0001] The utility model relates to the technical field of 3D printers, and in particular to a 3D printer capable of observing a wire extrusion process. Background Art

[0002] 3D printer, also known as three-dimensional printer, is a rapid prototyping process equipment. Rapid prototyping technology is to slice and layer the three-dimensional CAD solid model of the part according to a certain thickness to generate two-dimensional cross-sectional information. Then, based on the cross-sectional information of each layer, different methods are used to generate the shape of the cross-section. This process is repeated, and the cross-sections are superimposed layer by layer to finally form a three-dimensional entity.

[0003] At present, 3D printing technology has entered the campus, helping primary and secondary school students explore 3D printing technology, develop imagination, creativity and hands-on ability. The FDM 3D printer process consists of two processes: three-axis movement and melt extrusion. The three-axis movement is more intuitive, while the components of the melt extrusion process are a whole, and the extrusion process is obscured. Without disassembling the machine, the wire extrusion process cannot be observed intuitively, so the teaching effect cannot be effectively improved. Utility Model Content

[0007] The baffle is rotated so that the consumable material conveying section of the wire feeding component can be exposed;

[0008] The baffle is rotated, and the baffle can drive the bracket to rotate and separate the first arc ring body, so that one of the semi-conical shells sinks and is misaligned behind the other semi-conical shell to expose one end of the wire conveying section.

[0009] Furthermore, the outer wall of the other half cone shell is provided with two second arc ring bodies;

[0010] The first arc ring body abuts against the lower end of one of the second arc ring bodies, wherein

[0011] When the bracket separates the first arc ring body, the first arc ring body can press down against the upper end of another second arc ring body to position the two semi-conical shells after misalignment.

[0032] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] like Figure 1-4 As shown, a 3D printer capable of observing the wire extrusion process comprises: a wire feeding component 1, the wire feeding component 1 comprises a support plate, a driving motor arranged on the support plate, a driving wheel driven by the driving motor, a pressure rod with holes hinged on the support plate, a spring connected between the pressure rod and the support plate, a driven wheel connected to the pressure rod with holes is rotated, and the pressure rod can be pressed to drive the driven wheel away from the driving wheel to thread the consumables, and the pressure rod is loosened to make the wire hit between the driving wheel and the driven wheel. This is the prior art The wire feeding structure of the 3D printer in the operation is not explained in detail here. The connecting rod 2 is arranged on the wire feeding component 1, the baffle 3 rotatably connected to the connecting rod 2 for shielding the wire feeding component 1, two semi-conical shells 4 are arranged at the lower channel of the wire feeding component 1, one semi-conical shell 4 can be electrically connected to the heating element, and the other semi-conical shell 4 can conduct heat, a first arc ring body 5 is arranged on one of the semi-conical shells 4, and a bracket 6 is arranged on the baffle 3 and supports the first arc ring body 5;

[0034] The two semi-conical shells 4 are combined into a nozzle assembly, wherein

[0035] The baffle 3 is rotated so that the consumable material conveying section of the wire feeding component 1 can be exposed;

[0036] By rotating the baffle 3, the baffle 3 can drive the bracket 6 to rotate and separate the first arc ring body 5, so that one of the semi-conical shells 4 sinks and is misplaced behind the other semi-conical shell 4 to expose one end of the wire conveying section. Specifically, compared with the prior art, the wire feeding process of the wire feeding component 1 is shielded by the baffle 3 to increase the safety of the process. During teaching, the wire feeding process of the wire feeding component 1 can be exposed by rotating the baffle 3, so that the process can be observed intuitively, thereby increasing the teaching effect; and the rotation process of the baffle 3 causes the supporting force of the bracket 6 on the first arc ring body 5 to disappear, so that one of the semi-conical shells 4 loses its supporting force and forms a misaligned seam with the other semi-conical shell 4 for easy observation of the fusion state of the wire extrusion process, thereby helping students to effectively understand and improving the teaching quality of 3D printing.

[0037] Optionally, the outer wall of the other semi-conical shell 4 is provided with two second arc ring bodies 7;

[0038] The first arc ring body 5 abuts against the lower end of one of the second arc ring bodies 7, wherein

[0039] When the bracket 6 separates the first arc ring body 5, the first arc ring body 5 can press down against the upper end of the other second arc ring body 7 to position the two semi-conical shells 4 after being misaligned. Specifically, the inner diameters of the second arc ring body 7 and the first arc ring body 5 are both larger than the outer radius of the nozzle assembly, so that the second arc ring body 7 and the first arc ring body 5 have parallel parts in the vertical direction. The spacing between the two second arc ring bodies 7 limits the movable height of the first arc ring body 5, so that when one of the semi-conical shells 4 is misaligned with the other semi-conical shell 4, they will not be completely separated, thereby reducing interference with the consumables in the melt extrusion process and allowing the melt extrusion process to proceed normally.

[0040] Optionally, two fixing columns 8 are mirror-imaged between the two second arc ring bodies 7;

[0041] The first arc ring body 5 is provided with two through holes 9;

[0042] The two fixing columns 8 can be inserted into the two through holes 9, wherein

[0043] The first arc ring body 5 is suitable for descending along the two fixed columns 8 through the two through holes 9. Specifically, the two fixed columns 8 act on the first arc ring body 5 through the two through holes 9, and limit the first arc ring body 5 in the horizontal direction, so that the first arc ring body 5 cannot move away from the semi-conical shell 4 and the second arc ring body 7 by horizontal movement, thereby protecting the stability of the first arc ring body 5 in the active state.

[0044] Optionally, a slot 10 is provided on the connecting rod 2;

[0045] The card slot 10 is an inverted isosceles trapezoid, wherein

[0046] The baffle plate 3 is rotated, and the baffle plate 3 can be engaged with the slot 10. Specifically, the opening size of the slot 10 facing the baffle plate 3 is large, and the size of the bottom part of the slot 10 is small. After the baffle plate 3 is rotated, it gradually approaches the slot 10, so that the baffle plate 3 can move smoothly, and there is a clamping process from loose to tight, so that the baffle plate 3 can no longer interfere with the wire extrusion process after it moves.

[0047] Optionally, a hand-tightening bolt 11 is rotatably connected to the baffle plate 3, the baffle plate 3 has a circular hole for accommodating the hand-tightening bolt 11, the hand-tightening bolt 11 has two discs larger than the circular hole area, the hand-tightening bolt 11 can move spirally forward and backward in the circular hole, and a threaded hole 12 is provided on the wire feeding component 1;

[0048] The hand-tightening bolt 11 can be screwed to the threaded hole 12. Specifically, under normal circumstances, the position of the baffle 3 is fixed on the wire feeding component 1 through the connection of the hand-tightening bolt 11 to the threaded hole 12, thereby maintaining the integrity of the wire feeding component 1 and improving the efficiency of the printing work when it is not in the teaching process.

[0049] Optionally, the bracket 6 includes an L-shaped rod 13 and a semicircular ball 14 disposed on the L-shaped rod 13;

[0050] The spherical surface of the semi-circular sphere 14 can press against the lower end of the other second arc ring body 7. Specifically, one end of the L-rod 13 is connected to the baffle 3, and the movement of the baffle 3 drives the semi-circular sphere 14 to move through the L-rod 13. The apex of the arch surface of the semi-circular sphere 14 is in a position that just supports the second arc ring body 7. The shape setting of the semi-circular sphere 14 can reduce the friction resistance between it and the second arc ring body 7 in the moving state.

[0051] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
