Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a 3D printing consumable drying oven. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a technology that manufactures solid parts by adding materials layer by layer based on 3D CAD data. Because the filaments used in 3D printers are constantly exposed to air, moisture from the air can seep into the filament, increasing its humidity. When the filament is heated during use, this moisture turns into steam, which can create air bubbles within the filament, resulting in poor printing quality. Therefore, filaments are typically placed in a specialized drying chamber for drying before use to ensure 3D printing quality.

[0003] Currently, 3D printing filament drying ovens typically use a fan in conjunction with heating wires to heat and dry the interior. However, due to the limited internal space and the fact that the filaments are generally disc-shaped and occupy almost the entire cavity when placed inside the oven, it is difficult for the heat to quickly and effectively fill the entire space, resulting in many dead corners and significantly affecting the drying effect of the filaments. Utility Model Content

[0004] The purpose of this invention is to provide a 3D printing consumable drying oven. By incorporating support rollers, a fixed disc, multiple connecting arms, and rubber baffle rollers, the disc-shaped consumable can be placed on two support rollers, with multiple rubber baffle rollers inserted between the disc-shaped consumable. With the assistance of a control mechanism, the multiple rubber baffle rollers can be controlled to simultaneously move inward or outward, allowing them to abut against the inner wall of the disc-shaped consumable, thus limiting and fixing it. The fixed disc can then be controlled to rotate, and with the support of the support rollers, the fixed disc can drive the restricted disc-shaped consumable to rotate via the multiple rubber baffle rollers. As the disc-shaped consumable rotates, hot air is continuously blown by the heating element below, thus quickly and evenly heating and drying the consumable. This method is highly efficient, convenient, and has good performance, thus addressing the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 3D printing consumable drying oven, comprising:

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-5The 3D printing consumable drying oven shown includes:

[0027] Box 1, with a base 2 at the bottom of box 1, a heating component inside the base 2, and an exhaust valve 3 at the top of box 1.

[0028] The heating component includes a fan 4 located at the bottom of the base 2, and a heating wire 5 located above the fan 4 inside the base 2. The bottom of the housing 1 has multiple ventilation holes 6 that communicate with the base 2.

[0029] Multiple openings are provided on both sides of the base 2.

[0030] By starting the fan 4, in conjunction with the heating wire 5, hot air can be generated and blown towards the ventilation hole 6, and then enter the box 1 through the ventilation hole 6, thereby allowing the hot air to heat and dry the disc-shaped consumables placed in the box 1.

[0031] A fixed plate 8 is located inside one side of the housing 1, and the fixed plate 8 has an annular cavity 9 inside. Multiple support frames 12 are arranged in a circular array on the outside of the fixed plate 8. Movable sliders 13 are arranged inside the support frames 12. Multiple sliders 13 extend to one end outside the support frames 12 and are fixed with connecting arms 14 on one side of the fixed plate 8. A rubber baffle roller 15 is connected to one end of the connecting arm 14 relative to the slider 13. A rotating motor is arranged on the back of the housing 1, and the output end of the rotating motor is connected to the fixed plate 8.

[0032] The fixed disk 8 is equipped with a control mechanism, which is used to control multiple rubber rollers 15 to move inward or separate outward simultaneously.

[0033] Support rollers 7 are provided on both sides of the bottom of the box 1.

[0034] The control mechanism includes a movable ring 10 rotatably installed in the annular cavity 9. A toothed ring 11 is provided on the side wall of the movable ring 10. A threaded rod 16 is rotatably connected to the inside of the support frame 12 through a bearing. A slider 13 is threadedly connected to the outside of the threaded rod 16. One end of each of the multiple threaded rods 16 extends into the annular cavity 9 and is connected to a transmission gear 17, which meshes with the toothed ring 11.

[0035] A drive motor 18 is fixed to the top of the fixed disk 8. The output end of the drive motor 18 extends into the annular cavity 9 and is provided with a drive gear 19, which meshes with the gear ring 11.

[0036] Multiple limiting posts 20 are provided on the outer side of the movable ring 10, and a limiting groove 21 matching the limiting posts 20 is provided on the inner side of the annular cavity 9. Based on this, by setting the limiting posts 20 and the limiting groove 21, the stability of the movable ring 10 during rotation can be greatly guaranteed.

[0037] In use, the disc-shaped consumable can be placed inside the housing 1, with the disc-shaped consumable resting on two support rollers 7. At the same time, multiple rubber baffle rollers 15 are inserted in the middle of the disc-shaped consumable. By starting the drive motor 18, the drive motor 18 drives the drive gear 19 to rotate.

After that, the gear ring 11 can drive multiple transmission gears 17 to rotate, which in turn drives the threaded rod 16 to rotate. Under the action of the thread, the threaded rod 16 can drive the slider 13 to move within the support frame 12. Then the slider 13 drives the connecting arm 14 to move, which in turn drives the rubber baffle rollers 15 to move. This allows multiple sets of rubber baffle rollers 15 to move inward or outward simultaneously, so that the rubber baffle rollers 15 can abut against the inner wall of the middle of the disc-shaped consumable, thereby limiting and fixing the disc-shaped consumable.

[0038] Then, the rotating motor can be started to drive the fixed disk 8 to rotate. With the support of the support roller 7, the fixed disk 8 can drive the restricted disc-shaped consumable to rotate through multiple sets of rubber baffle rollers 15. As the disc-shaped consumable rotates, the heating component below continuously blows hot air, so that the consumable can be heated and dried quickly and evenly. It is efficient, convenient and has a good effect.
