[0002] In the widespread application of 3D printing technology, the quality of consumables directly affects the accuracy and performance of printed parts. PETG, as a high-performance engineering plastic, is favored for its excellent mechanical properties, chemical corrosion resistance, and good transparency. However, PETG consumables have strong hygroscopicity and easily absorb moisture from the air, leading to defects such as bubbles and stringing during high-temperature printing, thus affecting print quality. Therefore, effective moisture-proof measures must be taken when storing PETG consumables to ensure that the consumables are in a dry state.

[0003] Most consumable storage cabinets on the market typically use a simple airtight structure or add desiccants for moisture protection. However, these traditional methods have certain limitations. For example, ordinary desiccants have limited adsorption capacity and cannot be recycled, requiring regular replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof storage cabinet for 3D printing PETG consumables in order to solve the above-mentioned problems. It improves the problem that the moisture-proof storage cabinet for 3D printing PETG consumables usually adopts a simple airtight structure or adds desiccant for moisture protection. Ordinary desiccants have limited adsorption capacity and cannot be recycled, so they need to be replaced regularly.

[0005] This utility model achieves the above objectives through the following technical solution: a moisture-proof storage cabinet for 3D printed PETG consumables, comprising:

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] Please see Figures 1-5 The present invention provides the following technical solution:

[0037] A moisture-proof storage cabinet for 3D printed PETG filament, comprising:

[0038] Cabinet 1;

[0039] Multiple perforated placement plates 2 are fixedly connected to the inner walls of both sides of the cabinet 1 at the adjacent ends.

[0040] Motor 3 is fixedly connected to the upper end of cabinet 1 by bolts;

[0041] Threaded rod 4 is fixedly connected to the output shaft of motor 3 and rotatably connected inside cabinet 1;

[0042] Limiting rod 5 is fixedly connected to the upper and lower inner walls of cabinet 1 at the near ends;

[0043] Slider 6 is slidably connected to the circumferential surface of threaded rod 4 and limiting rod 5;

[0044] Fan 7 is fixedly connected to one side of slider 6 by bolts;

[0045] Mounting slot 8 is located on one inner wall of cabinet 1;

[0046] Mounting plate 9 is disposed within mounting slot 8;

[0047] Two heating blocks 10 are embedded in one side of the mounting plate 9, and both heating blocks 10 are attached to one side of the silica gel desiccant plate 11.

[0048] Silica gel desiccant plate 11 is fixedly connected to one side of the mounting plate 9;

[0049] Humidity sensor 12 is fixedly connected to the upper inner wall of cabinet 1;

[0050] PLC controller 13 is fixedly connected to one side of cabinet 1. PLC controller 13 is electrically connected to motor 3, humidity sensor 12 and heating block 10.

[0051] In a specific embodiment of this utility model, the cabinet 1 serves as the overall supporting frame and sealed space, internally accommodating PETG consumables to be stored. The perforated placement plate 2 not only supports the consumable reels but also facilitates airflow, improving drying efficiency. The motor 3 drives the threaded rod 4 to rotate. The system includes the threaded rod 4, a limiting rod 5, a slider 6, and a fan 7. The slider 6 has a sliding nut inside. Driven by the motor 3, the threaded rod 4 rotates, and the slider 6 moves up and down on the circumferential surfaces of the threaded rod 4 and the limiting rod 5. The limiting rod 5 guides the slider 6 to move only axially. The fan 7 moves accordingly with the slider 6, blowing airflow throughout the cabinet 1 onto the surface of the silica gel desiccant plate 11. The mounting groove 8 is used to install the mounting plate 9, which supports the heating block 10 and the silica gel desiccant plate 11. It is made of silicone particles and adhesive mixed and pressed together. It is used to absorb the moisture blown by the fan 7. After the silicone desiccant plate 11 absorbs the moisture, the heating blocks 10 are activated to heat it, which dries the silicone desiccant plate 11 and makes it reusable. Humidity sensor 12 and PLC controller 13 are used to monitor the humidity changes in the cabinet 1 in real time. When the humidity in the cabinet 1 exceeds the standard, the humidity sensor 12 feeds the data back to the PLC controller 13. The PLC controller 13 controls the motor 3 to start and drive the fan 7 to blow the moisture onto the surface of the silicone desiccant plate 11. The silicone desiccant plate 11 absorbs the moisture. When the humidity in the cabinet 1 is normal, the PLC controller 13 turns off the motor 3 and starts the heating blocks 10 to dry the silicone desiccant plate 11, so that the silicone desiccant plate 11 can be reused.

[0052] Please refer to the details. Figures 1-5 A cabinet door 14 is rotatably connected to one side of the cabinet body 1 via a pivot. A sealing groove 15 is provided on one side of the cabinet body 1. A sealing ring 16 is fixedly connected to one side of the cabinet door 14. The sealing groove 15 and the sealing ring 16 are matched.

[0053] In this embodiment: the cabinet door 14 is rotatably connected to the cabinet body 1 via a pivot, which makes it easy for users to open or close the cabinet door 14 to perform consumable storage and retrieval operations. When the cabinet door 14 is closed by personnel, the sealing groove 15 and the sealing ring 16 are tightly embedded in the sealing groove 15 to form good airtightness, preventing external moisture from entering the cabinet body 1, thereby effectively maintaining a dry environment inside the cabinet.

[0054] Please refer to the details. Figures 1-5 Two magnetic slots 17 are respectively opened on one side of the cabinet body 1, and two magnetic blocks 18 are respectively fixedly connected to one side of the cabinet door 14. The two magnetic slots 17 and the two magnetic blocks 18 are matched.

[0055] In this embodiment: the magnetic groove 17 and the magnetic block 18 are used so that when the cabinet door 14 is closed, the magnetic block 18 is embedded in the magnetic groove 17 and the magnetic attraction force is used to firmly attach the cabinet door 14 to the cabinet body 1, which significantly improves the closing stability of the cabinet door 14 and the overall sealing performance.

[0056] Please refer to the details. Figures 1-5 Each perforated placement plate 2 has a placement slot 19 connected to its upper end.

[0057] In this embodiment: the placement slot 19 is used to place boxed silica gel desiccant to assist in dehumidification and extend the shelf life of PETG materials.

[0058] Please refer to the details. Figures 1-5 One side of the cabinet 1 is rotatably connected to a maintenance door 20 via a pivot, and one side of the maintenance door 20 is fitted with a mounting plate 9.

[0059] In this embodiment: the maintenance door 20 is connected to the cabinet 1 via a pivot, making it easy for users to open and access the internal mounting plate 9. When the heating block 10 and the silica gel desiccant plate 11 are damaged, personnel can open the maintenance door 20 for replacement or repair.

[0060] Please refer to the details. Figures 1-5 An observation window 21 is fixedly connected to the surface of the cabinet door 14, and a handle 22 is fixedly connected to the surface of the cabinet door 14.

[0061] In this embodiment: the observation window 21 is used to allow users to easily understand the storage status of consumables in cabinet 1 and the operation of the equipment at any time; the handle 22 is used to allow users to open or close the cabinet door 14.

[0062] Please refer to the details. Figures 1-5 The lower end of the cabinet 1 is fixedly connected to multiple support columns 23, and the lower end of each support column 23 is fixedly connected to a gasket 24.

[0063] In this embodiment: the support column 23 is used to support the entire device, and the pad 24 is used to provide the device with anti-slip, shock absorption and ground protection functions. It not only enhances the stability of the device, but also adapts to different ground conditions and avoids the cabinet 1 from tilting or shaking due to uneven ground.

[0064] Personnel place PETG consumables onto the perforated placement plate 2 and close the cabinet door 14. The cabinet door 14 closes by rotating a pivot, and the magnetic block 18 is embedded in the magnetic groove 17, using magnetic attraction to enhance the sealing performance. At the same time, the sealing ring 16 is tightly embedded in the sealing groove 15, forming a good airtight environment to prevent external moisture from entering the cabinet 1. The humidity sensor 12 continuously monitors the humidity inside the cabinet, and all data is fed back to the PLC controller 13 in real time for intelligent judgment and control. When the humidity sensor 12 detects that the humidity inside the cabinet exceeds the set threshold, the PLC controller 13 starts the motor 3. Motor 3 drives the threaded rod 4 to rotate, and the slider 6 moves up and down along the surface of the threaded rod 4 and the limiting rod 5. While the slider 6 moves up and down, it drives the fan 7 to move synchronously. The fan 7 pushes the humid air towards the silica gel desiccant plate 11. The humid air is absorbed by the silica gel desiccant plate 11, thus drying the air. When the humidity inside the cabinet 1 returns to the normal level, motor 3 is turned off and fan 7 stops running. The heating blocks 10 are then activated. The two heating blocks 10 heat the silica gel desiccant plate 11, causing the desiccant to dehydrate and regenerate. The heating evaporates the moisture in the silica gel desiccant plate 11, restoring its moisture absorption capacity and enabling it to be reused.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
