Description

Technical Field

[0001] The utility model belongs to the technical field of consumable storage, and particularly relates to a 3D printing consumable winding disc for rapid dehumidification and drying. Background Art

[0002] Most 3D printing consumable filaments will absorb moisture from the air and become damp. When the damp consumable filament is heated by the nozzle, the moisture inside the consumable filament will quickly vaporize, causing the melted consumable filament to expand, generating bubbles, and resulting in problems such as wire drawing, holes, and reduced strength in the printed finished product, seriously affecting the printing quality. Therefore, the printing consumables need to be stored dry, and the consumable filaments to be used need to be dehumidified and dried.

[0003] Generally, a blast-type drying oven is used to dry 3D printing consumables. However, the existing winding methods of 3D printing consumable winding discs are to wind and stack the consumable filaments layer by layer outward from the core position of the wire disc. This layer-by-layer winding method causes the drying hot air to be unable to contact the inner-layer consumable filaments, unable to take away the moisture of the inner-layer consumable filaments, and at the same time, the moisture evaporated by the inner-layer consumable filaments is difficult to discharge, reducing the drying efficiency and making it difficult to ensure the drying effect.

[0004] Therefore, the above problems need to be solved urgently. Summary of the Utility Model

[0005] Utility Model Objective: In order to overcome the above deficiencies, the utility model provides a 3D printing consumable winding disc for rapid dehumidification and drying, which can send the drying air into the interior of the consumable filaments wound on the wire disc, saving the drying time of the consumable filaments, ensuring the drying effect of the consumable filaments, and guaranteeing the quality of 3D printed products.

[0006] Technical Solution: In order to achieve the above objective, the utility model provides a 3D printing consumable winding disc for rapid dehumidification and drying, including a core. The core is a hollow cylinder, and both ends of the core are connected with wing parts, and the wing parts are disc-shaped. The core is provided with fins. The fins are long strip-shaped, and the fins are arranged in an array around the axis of the core. A gap is left between two adjacent fins to form a first ventilation groove. When in use, the consumable wire is wound around the outside of the core, and the fins separate the consumable wire. The drying hot air contacts the surface of the inner consumable wire wound and stacked through the first ventilation groove between two fins, increasing the temperature of the consumable wire, taking away the moisture of the consumable wire, saving the drying time of the consumable wire, improving the drying efficiency, ensuring that the consumable wire is completely dry, and ensuring the drying effect. And the structure of the utility model is applicable to the injection mold demolding process, suitable for mass production, and saving production costs.

[0007] Further, in the above 3D printing consumable winding disc for rapid dehumidification and drying, the fins are provided with 2 layers or more along the axial direction of the core, and a cavity is left between the upper and lower layers of the fins. The consumables are wound in the cavity, increasing the contact area between the consumable wire and the heating air and improving the drying efficiency of the consumable wire.

[0008] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the cavity includes a wire winding cavity and a ventilation cavity. The wire winding cavity and the ventilation cavity are arranged at intervals. The consumable wire is wound around the wire winding cavity, and the ventilation cavity is communicated with the first ventilation groove. During use, the consumable wire is wound around the cavity at intervals, and the heated air flows through the ventilation cavity and the first ventilation groove, improving the heat exchange efficiency and the drying efficiency.

[0009] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the thickness of the wire winding cavity is equal to the diameter of the consumable wire. The consumable wire is stratified in single circles, increasing the contact area between the consumable wire and the heated air, improving the drying efficiency, ensuring that each circle of the consumable wire is in contact with the heated air, and ensuring the drying effect.

[0010] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the wing part is provided with through grooves, and the through grooves are arranged in an array around the center of the wing part. The through grooves can reduce the weight of the wire winding disc, reduce the transportation cost, and reduce the manufacturing cost. The heated air can pass through the through grooves on both sides and through the first ventilation groove between the fins, increasing the air flow rate and the drying efficiency of the consumable wire.

[0011] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the through grooves are fan-shaped, and there are two or more through grooves.

[0012] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the core includes an inner core and an outer core, and the inner core and the outer core are connected by rib parts. A plurality of rib parts are arranged around the axis of the inner core. The inner core is a hollow cylinder, and the outer core is arranged outside the inner core.

[0013] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, a second ventilation groove is provided between the inner core and the outer core. The heated air flows through the second ventilation groove, heating the outer core, increasing the temperature of the consumable wire wound on the innermost layer, improving the drying efficiency, and ensuring the drying effect.

[0014] Furthermore, in the above-mentioned 3D printing consumable wire winding disc for rapid dehumidification drying, the outer core is provided with through holes, and the second ventilation groove is communicated with the first ventilation groove through the above-mentioned through holes. The heated air passes through the first ventilation groove and the second ventilation groove, ensuring the flow rate of the heated air, reducing the loss, improving the drying efficiency, and ensuring the drying effect.
