Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing consumable boxes, in particular to a drying device and a 3D printing consumable box using the same. Background Art

[0002] Fused Deposition Modeling (FDM) 3D printers have become one of the most widely used 3D printing technologies. This technology builds models by heating plastic filaments to a molten state and depositing them layer by layer. Therefore, the selection and processing of materials are particularly crucial. Most 3D printing consumables, especially polymer materials, are prone to moisture absorption. When these materials are exposed to air, especially in a humid environment, they will absorb moisture from the air. At this time, the damp consumables may vaporize rapidly when heated, causing the melt to expand, the flow rate to increase, resulting in pores, and causing a series of problems such as wire drawing, material leakage, holes, rough surface, and low strength in the printed parts.

[0003] Therefore, workers need to use a drying device to dry the consumables, and then manually put the dried consumables into a sealed packaging bag or a sealed box to keep the consumables in a dry state. Since the consumables usually need to be baked for several hours to more than ten hours, if they cannot be put into the sealing device in time after drying, the consumables will absorb moisture again.

[0004] To solve this problem, the operation time of the drying device can be adjusted so that the drying device is in a heating state for a long time to maintain the internal dry level and the dry state of the consumables. This approach will waste a large amount of energy and there is a risk of damaging the consumables due to too long baking time. Content of the Utility Model

[0005] In view of the above defects, the utility model provides a drying device and a 3D printing consumable box using the same. After drying, the driving end of the lifting component drives the end cover to descend, so that the end cover closes the hot air inlet and the waste gas outlet, which not only effectively avoids the entry of external moisture into the consumables and the situation of the consumables getting damp again, but also can reduce the operation time of the drying device in this solution, and solves the problem of large energy consumption caused by the long-term operation of the drying device.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

The two second partition portions are respectively fixedly connected to the two end portions of the first partition portion, so that the end cover sequentially forms a second guiding air duct, a first guiding air duct and a second guiding air duct from left to right.

[0015] A heating fan is arranged in the hot air duct. The air inlet of the heating fan faces the hot air inlet, and the air outlet of the heating fan faces the hot air outlet.

[0030] The following Figures 1 to 5 describes a drying device according to an embodiment of the present utility model and a 3D printing consumable box using the same.

[0031] A drying device includes a main body 1, an end cover 2, and a lifting assembly 3. A baffle 11 is provided in the inner cavity of the main body 1. The baffle 11 vertically divides the inner cavity of the main body 1 to form a hot air duct 12 and an exhaust gas duct 13. A notch is provided at the top of the main body 1. The baffle 11 divides the notch to form a hot air inlet and an exhaust gas outlet. A hot air outlet 14 and an exhaust gas inlet 15 are provided at the bottom of the main body 1. The hot air duct 12 communicates with the hot air inlet and the hot air outlet 14, and the exhaust gas duct 13 communicates with the exhaust gas inlet 15 and the exhaust gas outlet.

[0032] The lifting assembly 3 is installed on the main body 1. The lifting end of the lifting member 31 is fixedly connected to the end cover 2. The end cover 2 movably penetrates through the top of the main body 1 to open or close the hot air inlet and the exhaust gas outlet.

[0033] A drying device of this solution is installed on the consumables, and both the hot air inlet and the exhaust gas outlet communicate with the inner cavity of the consumables. The fixed connection design of the lifting assembly 3 and the end cover 2 enables the end cover 2 to flexibly open or close the hot air inlet and the exhaust gas outlet through the lifting assembly 3. When drying is required, the lifting assembly 3 can drive the end cover 2 to movably penetrate through the top of the main body 1, thereby opening or closing the hot air inlet and the exhaust gas outlet, so that hot air can enter the hot air duct 12 and then be discharged from the hot air outlet 14 under the guidance of the hot air duct 12 to perform a drying operation on the object. At the same time, the exhaust gas generated during the drying process can enter the main body 1 from the exhaust gas inlet 15 and be discharged from the exhaust gas outlet under the guidance of the exhaust gas duct 13, effectively solving the problem that it is difficult for traditional drying devices to discharge the exhaust gas with water vapor, resulting in the exhaust gas accumulating in the consumables and causing the consumables to absorb moisture again.

[0034] After drying is completed, the driving end of the lifting assembly 3 drives the end cover 2 to descend, so that the end cover 2 closes the hot air inlet and the waste gas outlet. This not only effectively prevents external moisture from entering the consumables and causing the consumables to get damp again, but also reduces the operation time of the drying device in this solution, solving the problem of large energy consumption during long-term operation of the drying device.

[0035] Moreover, the baffle 11 vertically divides the inner cavity of the main body 1, so that the inner cavity of the main body 1 forms independent hot air ducts 12 and waste gas ducts 13, which can ensure the complete isolation of hot air and waste gas, avoiding the pollution of hot air by waste gas during transmission, and thus ensuring the quality and efficiency of hot air.

[0036] The lifting assembly 3 is provided with a lifting member 31 and a connecting rod 32. The lifting member 31 is installed in the hot air duct 12. The bottom of the connecting rod 32 is fixedly connected to the driving end of the lifting member 31, and the top of the connecting rod 32 is fixedly connected to the end cover 2.

[0037] It should be noted that the lifting member 31 is a thermal actuator. The driving end of the lifting member 31 is fixedly connected to the bottom of the connecting rod 32, so that the end cover 2 can be opened or closed to expose the notch at the top of the main body 1.

[0038] The end cover 2 includes a top plate 21 and a partition plate 22. The connecting rod 32 is fixedly connected to the bottom of the top plate 21. The partition plate 22 is located at the bottom of the top plate 21. The top plate 21 is adapted to the notch. The partition plate 22 includes a first partition portion 23 and a second partition portion 24. The first partition portion 23 is adapted to the inner wall of the hot air duct 12, and the second partition portion 24 is adapted to the inside of the waste gas duct 13;

[0039] The first partition portion 23 and the top plate 21 form a first guiding air duct 25, and the first guiding air duct 25 is communicated with the input end of the hot air duct 12. The second partition portion 24 and the top plate 21 form a second guiding air duct 26, and the second guiding air duct 26 is communicated with the input end of the waste gas duct 13.

[0040] The design of the first partition portion 23 and the second partition portion 24 forms the first guiding air duct 25 and the second guiding air duct 26 between the end cover 2 and the main body 1. When the lifting assembly 3 drives the end cover 2 to rise, both the first guiding air duct 25 and the second guiding air duct 26 are communicated with the outside, so that the main body 1 conveys hot air inward while discharging waste gas outward. Among them, the first guiding air duct 25 and the second guiding air duct 26 are independent and isolated from each other, ensuring that the hot air in the hot air duct 12 can flow smoothly without mixing with the waste gas in the waste gas duct 13.

[0041] The input end of the first guiding air duct 25 is arranged opposite to the output end of the second guiding air duct 26.

[0042] By arranging the input end of the first guiding air duct 25 and the output end of the second guiding air duct 26 in opposite directions, it can be ensured that the airflows in the two air ducts do not interfere with each other, forming an obvious isolation effect. Since the directions of the first guiding air duct 25 and the second guiding air duct 26 are opposite, the hot air in the hot air duct 12 will not flow backward into the exhaust gas duct 13. Similarly, the exhaust gas in the exhaust gas duct 13 will not enter the hot air duct 12, further preventing the hot air in the hot air duct 12 from mixing with the exhaust gas in the exhaust gas duct 13, and ensuring the purity and stability of the respective airflows.

[0043] There are two baffles 11, and the two baffles 11 divide the inner cavity of the main body 1, so that the inner cavity of the main body 1 successively forms an exhaust gas duct 13, a hot air duct 12, and an exhaust gas duct 13 from left to right;

[0044] There are two second partition parts 24, and the two second partition parts 24 are respectively fixedly connected to the two end parts of the first partition part 23, so that the end cover 2 successively forms a second guiding air duct 26, a first guiding air duct 25, and a second guiding air duct 26 from left to right.

[0045] The hot air duct 12 is designed between the exhaust gas ducts 13. Such a layout enables the hot air duct 12 to absorb part of the heat energy of the exhaust gas in the exhaust gas ducts 13 on both sides, thereby improving the efficiency of heat energy recovery. This helps to reduce energy consumption and enhance the energy efficiency of the system.

[0046] At this time, there are two exhaust gas ducts 13. If one exhaust gas duct 13 fails, the hot air duct 12 and the other exhaust gas duct 13 can still operate normally, effectively ensuring the continuity and stability of the system, and reducing the interruption or downtime of the drying device caused by the failure.

[0047] A heating fan 4 is arranged in the hot air duct 12. The air inlet of the heating fan 4 faces the hot air inlet, and the air outlet of the heating fan 4 faces the hot air outlet 14.

[0048] The air inlet of the heating fan 4 directly faces the hot air inlet, so that air can be quickly sucked into the heating fan 4, and then heated in the heating fan 4 to form hot air. At the same time, the powerful power of the heating fan 4 quickly pushes the hot air to the hot air outlet 14, enabling the drying device of this solution to blow out hot air evenly, thereby improving the drying speed of the drying device.

[0049] A 3D printing consumables box includes a box, a controller and a drying device, wherein the controller is electrically connected to the drying device, the bottom of the main body 1 is installed inside the box, the hot air outlet 14 is connected to the inside of the box, and the exhaust gas inlet 15 is connected to the inside of the box.

[0050] The drying device is mounted on the box, and the hot air outlet 14 and the exhaust air inlet 15 are both connected to the interior of the box. The controller starts the drying device, and the hot air outlet 14 of the drying device is directly connected to the interior of the box, so that the hot air can be quickly and evenly distributed around the consumables, thereby achieving efficient drying, effectively keeping the consumables in a dry state, and preventing the consumables from being deteriorated or damaged due to moisture.

[0051] The waste gas inlet 15 is connected to the box body, so that the waste gas and water molecules generated during the drying process can be directly discharged from the box body through the waste gas inlet 15 and the waste gas pipe 13, which can effectively reduce the accumulation of water vapor in the box body and cause the box body to absorb moisture again.

[0052] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
