Description

Technical Field

[0001] This utility model belongs to the field of 3D printing equipment technology, specifically relating to a fluorescence generation device for 3D printing filaments. Background Technology

[0002] 3D printing is a technology that uses digital model files as a basis and employs powdered metal or plastic and other bondable materials to construct objects layer by layer. The consumables of 3D printers typically include PLA, ABS, photosensitive resin, wax-based materials, nylon powder, plaster-like powder, metal powder and other materials. Different 3D printers use different materials for printing. For the manufacture of some fluorescent models, fluorescent filaments are required.

[0003] The prior art includes a 3D printing fluorescent filament generation device with patent publication number CN220219701U. This patent uses a dyeing device to transport filaments wound on a spool to the dyeing device, which sprays a fluorescent agent onto the surface of the filaments and then cures it by irradiation, thereby producing fluorescent filaments. The fluorescent filaments are then transported into a filament hot-melt extrusion head, where they are hot-melt printed to form a fluorescent model. However, in actual use, the following shortcomings still exist: In practice, dust easily adheres to the outer surface of the printed filaments before fluorescent dyeing. During the fluorescent dyeing process, the dust on the outer surface of the filaments can easily affect the dyeing effect. Furthermore, the dyeing nozzle can spray the filaments unevenly, resulting in poor fluorescent dyeing effects.

[0004] Therefore, there is a need for a fluorescence generation device for 3D printing filaments to solve the problems in the existing technology where dust easily adheres to the outer surface of the printing filaments, affecting the fluorescence dyeing effect, and the fluorescence generation device is not easy to uniformly dye the printing filaments. Utility Model Content

[0005] The purpose of this invention is to provide a fluorescence generation device for 3D printing filaments to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fluorescence generation device for 3D printing filaments, comprising a mounting box, a dyeing pipe fixedly connected to one side of the outer wall of the mounting box, a plurality of circumferentially distributed nozzles being provided on the outer surface of the dyeing pipe, the output ends of the plurality of nozzles extending into the dyeing pipe and facing the axis of the dyeing pipe, an inlet pipe fixedly connected to the center of the other side of the outer wall of the mounting box, a cleaning mechanism being provided inside the mounting box, and a dyeing assembly being provided inside the dyeing pipe;

[0007] The cleaning mechanism includes two symmetrically distributed housings, which are respectively fixedly connected to the inner walls of both ends of the mounting box. A limit plate is slidably connected to the inner wall of the housing. Two parallel springs are fixedly connected to the outer wall of one end of the limit plate. The ends of the springs away from the limit plate are fixedly connected to the inner wall of one end of the mounting box. A cleaning brush is fixedly connected to the outer wall of the other end of the limit plate. The cleaning brush slides through the outer wall of one end of the housing, and the bristles of the cleaning brush are in contact with the outer surface of the wire.

[0008] It should be noted in the solution that the dyeing assembly includes a smear, a through hole, and a fixing plate. The smear is fixedly connected to the inner surface of the dyeing pipe and is flat-topped and conical. The through hole is opened at the bottom of the outer surface of the dyeing pipe. There are two fixing plates that are distributed in parallel. Both fixing plates are fixedly connected to the bottom of the outer surface of the dyeing pipe and are located on both sides of the through hole. A collection box is movably arranged between the two opposite sides of the two fixing plates. Fixing screws are threaded into the outer walls of both sides of the collection box and the two fixing plates.

[0009] It is worth noting that a fixing column is fixedly connected to the top of the outer surface of the dyeing pipe, a drive motor is fixedly connected to the top of the fixing column, and a drive gear is coaxially fixedly connected to the output end of the drive motor.

[0010] Furthermore, it should be noted that a bearing is fastened to one side of the outer surface of the dyeing pipe, and a sleeve is rotatably connected to the outer surface of the dyeing pipe through the bearing. Multiple curing lamps distributed in a circle are fixedly connected to the inner surface of the sleeve, a driven gear is fastened to the outer surface of the sleeve, and an outlet pipe is fixedly connected to the center of the outer wall of one side of the sleeve.

[0011] In a preferred embodiment, the nozzle is arranged at an angle, and the driving gear is meshed with the driven gear.

[0012] In a preferred embodiment, the inlet pipe, the trowel, and the outlet pipe are coaxially arranged, and the through hole is located near the larger side of the trowel.

[0013] Compared with the prior art, the fluorescence generation device for 3D printing filaments provided by this utility model has at least the following beneficial effects:

[0014] (1) The cleaning mechanism cleans the outer surface of the printing line by the cleaning brush, reducing the dust on the outer surface of the printing line and reducing the impact of dust on the dyeing effect. It is easy to use and effectively avoids the problem that dust easily adheres to the outer surface of the printing line and affects the fluorescent dyeing effect.

[0015] (2) By combining the nozzle and the dyeing component, the nozzle is connected to the external fluorescent agent supply device to spray the fluorescent agent on the outer surface of the printing line. The smear evenly spreads the dye on the outer surface of the printing line. The fluorescent dye on the outer surface of the printing line is cured by the set curing lamp. The fluorescent dyeing effect is good, which effectively avoids the problem that the fluorescent generating device is not easy to dye the printing line evenly. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figures 1-4 This utility model provides a fluorescence generation device for 3D printing filaments, including a mounting box 1. A dyeing pipe 2 is fixedly connected to one side of the outer wall of the mounting box 1. Multiple nozzles 3 are arranged in a circular pattern on the outer surface of the dyeing pipe 2. The output ends of the multiple nozzles 3 extend into the dyeing pipe 2 and face the axis of the dyeing pipe 2. An inlet pipe 4 is fixedly connected to the center of the other side of the outer wall of the mounting box 1. A cleaning mechanism 5 is provided inside the mounting box 1. A dyeing component 6 is provided inside the dyeing pipe 2.

[0023] The cleaning mechanism 5 includes two symmetrically distributed housings 51, which are fixedly connected to the inner walls of both ends of the mounting box 1. A limiting plate 52 is slidably connected to the inner wall of the housing 51. Two parallel springs 53 are fixedly connected to the outer wall of one end of the limiting plate 52. The end of the spring 53 away from the limiting plate 52 is fixedly connected to the inner wall of one end of the mounting box 1. A cleaning brush 54 is fixedly connected to the outer wall of the other end of the limiting plate 52. The cleaning brush 54 slides through the outer wall of one end of the housing 51, and the bristles of the cleaning brush 54 are in contact with the outer surface of the wire.

[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the dyeing assembly 6 includes a smear 61, a through hole 62, and a fixing plate 63. The smear 61 is fixedly connected to the inner surface of the dyeing pipe 2 and is flat-topped and conical. The through hole 62 is opened at the bottom of the outer surface of the dyeing pipe 2. There are two fixing plates 63, which are distributed in parallel. Both fixing plates 63 are fixedly connected to the bottom of the outer surface of the dyeing pipe 2 and are located on both sides of the through hole 62. A collection box 64 is movably arranged between the opposite sides of the two fixing plates 63. Fixing screws 65 are threadedly inserted between the outer walls of both sides of the collection box 64 and the two fixing plates 63.

[0025] Further as Figure 1 As shown, it is worth noting that a fixed column 7 is fixedly connected to the top of the outer surface of the dyeing pipe 2, a drive motor 8 is fixedly connected to the top of the fixed column 7, and a drive gear 9 is fixedly connected to the output end of the drive motor 8 on the same axis.

[0026] Further as Figure 1 and Figure 4 As shown, it is worth noting that a bearing 10 is fastened to one side of the outer surface of the dyeing pipe 2, and a sleeve 11 is rotatably connected to the outer surface of the dyeing pipe 2 through the bearing 10. Multiple curing lamps 12 distributed in a circle are fixedly connected to the inner surface of the sleeve 11, a driven gear 13 is fastened to the outer surface of the sleeve 11, and an outlet pipe 14 is fixedly connected to the center of the outer wall on one side of the sleeve 11.

[0027] Further as Figure 1 As shown, it is worth noting that the nozzle 3 is set at an angle to avoid mutual interference between multiple nozzles 3 during dyeing, thereby affecting the dyeing effect. The driving gear 9 is meshed with the driven gear 13, which facilitates the rotation of the sleeve 11 by the drive motor 8.

[0028] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that the inlet tube 4, the smear plate 61, and the outlet tube 14 are coaxially arranged to facilitate the wires to pass through the device. The through hole 62 is close to the larger side of the smear plate 61 to facilitate the collection of excess fluorescent agent scraped off by the smear plate 61.

[0029] In summary: When using this device, the printing filament is first fed into the installation box 1 through the inlet pipe 4 using the feeding device. At this time, the printing filament passes between the two cleaning brushes 54. The cleaning brushes 54 clean the outer surface of the printing filament, reducing dust on the outer surface of the printing filament and reducing the impact of dust on the dyeing effect. The cleaned printing filament enters the dyeing pipe 2 for fluorescent dyeing, effectively avoiding the problem that dust easily adheres to the outer surface of the printing filament and affects the fluorescent dyeing effect.

[0030] Connect the nozzle 3 to an external fluorescent agent supply device, and simultaneously turn on the drive motor 8 and curing lamp 12. The cleaned printing filament enters the dyeing pipe 2, and multiple nozzles 3 spray the outer surface of the printing filament to fluorescently dye it. After spraying, the printing filament passes through the smear plate 61, which spreads the fluorescent agent evenly on the outer surface of the printing filament. The evenly spread printing filament enters the sleeve 11. At this time, the drive motor 8 drives the drive gear 9 to rotate. Under the meshing connection of the drive gear 9 and the driven gear 13, the sleeve 11 rotates synchronously through the bearing 10, which in turn drives multiple curing lamps 12 to rotate and cure the fluorescent dye on the outer surface of the printing filament. The fully dyed printing filament is discharged through the outlet pipe 14, effectively avoiding the problem that the fluorescent generating device is not easy to uniformly dye the printing filament.

[0031] The drive motor 8 and curing lamp 12 can be purchased from the market. The drive motor 8 and curing lamp 12 are equipped with power supplies. They are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
