Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to an anti-winding material guiding mechanism for a 3D printer. Background Technology

[0002] 3D printers work on the principle of layer-by-layer manufacturing technology, which involves slicing a digital model into layers of printing instructions and controlling the print head or laser beam to deposit material layer by layer to form a solid object.

[0003] Traditional 3D printers use a filament winding system to wind filaments. As the printer operates, the filaments are drawn from the filament winding system and fed into the printer. The printer then processes and shapes the filaments. However, traditional filament winding systems lack the ability to trim or secure the filaments, which can cause them to scatter or become entangled during the drawing process. This reduces the smoothness of filament feeding or even prevents feeding altogether, potentially leading to malfunctions in the 3D printer. Utility Model Content

[0004] This invention provides an anti-tangling material guiding mechanism for 3D printers, which solves the problem that in traditional 3D printers, the filament is wound onto a winding drum and then pulled out of the drum as the printer operates. Traditional winding drums do not have the function of trimming or securing the filament, which leads to the filament easily scattering and tangling during the extraction process. This reduces the smoothness of filament feeding or even prevents feeding altogether, which can easily cause malfunctions in the 3D printer.

[0005] This utility model provides a 3D printer anti-tangle material guiding mechanism, specifically including: a material guiding spool, inside which a spool support shaft is rotatably connected via bearings; each end of the spool support shaft is fitted with a support end plate via screws; two guide plates are connected between the two support end plates; two lifting push cylinders are movably connected inside the material guiding spool; two push cylinder guide rods are fixedly connected to the side of each lifting push cylinder away from the center of the material guiding spool; a push-pull spring is fixedly connected to the outer end of each push cylinder guide rod; the push cylinder guide rod is movably connected to the guide plate; and the other end of the push-pull spring is fixedly connected to the guide plate. The lifting pusher cylinder has a pusher cylinder opening near the center of the guide cylinder. Three three-way support shafts are fixedly connected to the inner wall of the lifting pusher cylinder. The axes of the three three-way support shafts are all parallel to the axis of the lifting pusher cylinder. The three three-way support shafts are evenly distributed on the inner wall of the lifting pusher cylinder. The two ends of the three-way support shafts are rotatably connected to evenly distributed support cylinders through bearings. A wire limiting swivel is connected inside the lifting pusher cylinder. The wire limiting swivel is coaxial with the lifting pusher cylinder. The outer surface of the wire limiting swivel is tumbled to the evenly distributed support cylinders. The two ends of the wire limiting swivel are slidably connected to the inner wall of the winding area side of the guide cylinder.

[0006] Furthermore, a rotating shaft is vertically welded to the middle of the side of the support shaft end plate away from the spool support shaft, and limit sockets are provided at the upper and lower ends of the side of the support shaft end plate connected to the spool support shaft.

[0007] Furthermore, the front opening of the limiting socket is connected to the front surface of the support shaft end plate, and a spiral hole is opened transversely inside the limiting socket, with a limiting bolt spirally installed inside the spiral hole.

[0008] Furthermore, the two ends of the guide plate are slidably connected to the limiting sockets of the two shaft end plates, and the left and right end faces of the guide plate are respectively provided with a plate limiting socket.

[0009] Furthermore, the inner end of the limiting bolt is inserted into the limiting socket of the insert plate.

[0010] Furthermore, the axis of the lifting pusher is parallel to the axis of the guide cylinder, and the opening of the pusher faces the center of the guide cylinder.

[0011] This utility model provides an anti-winding material guiding mechanism for a 3D printer, which has the following beneficial effects: In this utility model of the 3D printer, the material guide spool has been improved. It is equipped with a reinforcement structure for the consumable in the spool. During the material guiding process, the material guide spool rotates outside the spool support shaft. At the same time, it is connected to the consumable in the winding state in the material guide spool by the spool limiting screw and is tightly pushed. The consumable in the winding state is limited and reinforced, so as to avoid the consumable from becoming entangled or scattered due to lack of limiting and looseness.

[0012] Furthermore, in the 3D printer feeding mechanism of this utility model, the reinforcing structure used to reinforce the filament roll is detachable, which facilitates the replacement and installation of the filament roll. It is flexible in use and suitable for securing filaments of different materials, diameters, and hardness. The structure is compact, and while increasing functionality, the volume of the feeding structure is effectively limited, maintaining the compactness of the feeding mechanism structure.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Please refer to Figures 1 to 6 : This utility model proposes an anti-tangle material guiding mechanism for a 3D printer, comprising: a material guiding spool 1, a spool support shaft 2 rotatably connected inside the material guiding spool 1 via bearings, a support shaft end plate 3 mounted at each end of the spool support shaft 2 by screws, two guide plates 4 connected between the two support shaft end plates 3, two lifting push cylinders 5 movably connected inside the material guiding spool 1, two push cylinder guide rods 501 fixedly connected to the side of the lifting push cylinder 5 away from the center of the material guiding spool 1, a push-top tension spring 502 fixedly connected to the outer end of the push cylinder guide rod 501, a guide plate 4 movably connected to the push cylinder guide rod 501, and a guide plate 4 fixedly connected to the other end of the push-top tension spring 502, a push cylinder through-hole 503 opened near the center of the material guiding spool 1 on the lifting push cylinder 5, and three three-way support shafts 504 fixedly connected to the inner wall of the lifting push cylinder 5, the axes of the three three-way support shafts 504 being parallel to the axis of the lifting push cylinder 5, and the three three-way support shafts 504 being evenly spaced. Distributed along the inner wall of the lifting push cylinder 5, the three-way support shaft 504 has bearings at both ends that are rotatably connected to evenly distributed support cylinders 505. A wire limiting swivel column 6 is connected inside the lifting push cylinder 5, coaxial with the lifting push cylinder 5. The outer surface of the wire limiting swivel column 6 is in rolling contact with the evenly distributed support cylinders 505, and the two end faces of the wire limiting swivel column 6 are slidably connected to the inner wall of the winding area side edge of the guide wire drum 1. Under normal conditions, the wire is wound through the guide wire drum 1, and the push spring 502... The lifting cylinder 5 is pushed downwards to make the wire limiting screw 6 fit tightly against the wire wound in the guide cylinder 1, effectively limiting the wire and preventing the wound wire from loosening inside the guide cylinder 1. As the wire is pulled out, the guide cylinder 1 rotates, causing the wire limiting screw 6 to roll on the surface of the wire, maintaining the reinforcement of the wire while the guide cylinder 1 is rotating, and not affecting the extraction of the wire, thus preventing the wire from scattering or tangling in the guide cylinder 1.

[0019] In this embodiment, the axis of the lifting push cylinder 5 is parallel to the axis of the guide cylinder 1, and the opening of the push cylinder through 503 faces the center of the guide cylinder 1. Through the setting of the lifting push cylinder 5 and the evenly distributed support cylinder 505, the wire limiting spiral column 6 is movably connected inside the lifting push cylinder 5 and is rotatably connected with the evenly distributed support cylinder 505, which limits the wire limiting spiral column 6 and keeps it free to rotate. The two ends of the wire limiting spiral column 6 are kept in contact with the two sides of the guide cylinder 1, reducing gaps and preventing the wire from getting stuck due to detachment through the gaps.

[0020] In Example 2, based on Example 1, a rotating shaft 301 is vertically welded to the middle of the side of the support end plate 3 away from the spool support shaft 2. Limiting slots 302 are provided at both the upper and lower ends of the side of the support end plate 3 connected to the spool support shaft 2. The front opening of the limiting slot 302 connects to the front surface of the support end plate 3. A spiral hole 303 is transversely provided inside the limiting slot 302, and a limiting bolt 304 is spirally installed inside the spiral hole 303. The two ends of the guide plate 4 are slidably connected to the inside of the limiting slots 302 of the two support end plates 3. A limiting plate is provided on the left and right end faces of the guide plate 4. The inner end of the limiting bolt 304 is inserted into the limiting insertion hole 402 of the insert plate. Under normal conditions, the limiting bolt 304 is connected to the spiral hole 303 and the limiting insertion hole 402 of the insert plate to limit the guide plate 4 and prevent the guide plate 4 from moving between the two support shaft end plates 3. When replacing the wire in the guide tube 1, the limiting bolt 304 can be rotated and removed to pull the guide plate 4 forward from between the two support shaft end plates 3. After the guide plate 4 is removed, the lifting push cylinder 5 can be pulled out of the guide tube 1, so that the guide tube 1 can be restored to free rotation, so as to replace and organize the wire in the guide tube 1.

[0021] The working principle of this embodiment is as follows: First, under normal conditions, the filament is wound and stored in the guide spool 1. As the 3D printer operates, the filament is extracted from the spool and fed into the 3D printer. The guide spool 1 rotates, and at this time, under the action of the push spring 502, the lifting push cylinder 5 is pushed downward, so that the filament limiting spiral post 6 is tightly attached to the filament wound in the guide spool 1, preventing the filament from loosening. At the same time, as the guide spool 1 rotates, the filament limiting spiral post 6 and the filament interact. The rolling mechanism keeps the wire pressed down without affecting the wire feeding. As the wire is consumed, the lifting pusher 5 can maintain the tight fit between the wire limiting spindle 6 and the wire under the action of the push spring 502, thus maintaining the wire winding tightness. When replacing the wire, the limiting bolt 304 can be rotated and removed, and the guide plate 4 can be pulled forward from between the two support shaft end plates 3, so that the guide tube 1 can be disassembled, so as to replace the guide tube 1 or rewind the wire in the guide tube 1.
