Description

Technical Field

[0001] This utility model relates to the field of 3D printing consumables storage technology, specifically a vacuum moisture-proof storage box for 3D printing consumables. Background Technology

[0002] The rapid development of 3D printing technology has driven the widespread application of various printing consumables (such as PLA, ABS, PETG filaments, and metal powders). The storage environment of these consumables directly impacts print quality. Filaments made of polymer materials such as PLA and ABS easily absorb moisture from the air, leading to problems like bubbles and stringing during printing due to moisture evaporation, resulting in decreased model accuracy or even print failure. Metal powders, on the other hand, may oxidize and agglomerate due to moisture, affecting their flowability and molding performance. Therefore, vacuum moisture-proof storage of 3D printing consumables is a crucial step in ensuring print quality.

[0003] In existing technologies, vacuum moisture-proof storage boxes for 3D printing consumables typically employ a single-layer shell structure. An air extraction device draws air out of the box to create a negative pressure environment, which, combined with sealing components, achieves a moisture-proof effect. While this structure can meet basic storage needs to a certain extent, it reveals significant drawbacks during long-term use: due to its single-layer design, the box's structural strength is limited, and under repeated cycles of vacuuming to create negative pressure, the box is prone to irreversible deformation due to the pressure difference between the inside and outside.

[0004] Specifically, the sealing edges between the lid and the body warp, leading to a decrease in sealing performance and easy penetration of external moisture; some weak areas may even develop cracks, directly resulting in the loss of vacuum storage function.

[0005] In addition, deformation of a single-layer structure can trigger a chain of problems: on the one hand, the deformed box is difficult to maintain a stable negative pressure state, and frequent air extraction is required to compensate for air leakage, which not only increases energy consumption, but also reduces the ease of use.

[0006] On the other hand, deformation of the box may compress the consumables stored inside, causing wire and spool deformation, powder can tipping over, etc., affecting the integrity of the consumables. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a vacuum moisture-proof storage box for 3D printing consumables, which solves the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vacuum moisture-proof storage box for 3D printing consumables, comprising a storage box body;

[0009] The main body of the storage box is a cylinder with a hollow interior and an open upper surface. A sealing cap is threaded to the outside of the main body of the storage box. The bottom of the main body of the storage box and the top of the sealing cap are both concave to form a concave part. A vacuum one-way valve communicating with the main body of the storage box is provided inside the upper concave part.

[0011] A support plate is also provided between the support member and the inner wall of the storage box body. The support plate, the storage box body and the support member together form a triangular support structure.

[0012] Furthermore, the cross-sectional shape of the upper end face of the support member is a regular hexagon.

[0013] Furthermore, multiple uprights are vertically installed on the inner bottom wall of the storage box body for placing D consumable coils.

[0014] Furthermore, the number of the uprights is seven, with one of the uprights installed at the center of the bottom wall inside the storage box body;

[0017] Furthermore, a rotating component is provided on the outside of the main body of the storage box, and the upper cross-section of the rotating component is a regular hexagon.

[0018] Furthermore, a rubber sealing ring is provided between the support member and the sealing cover.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] 1.

[0026] 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.

[0027] Please see Figure 1-3 The 3D printing consumable vacuum moisture-proof storage box in this embodiment includes a storage box body 1, a sealing cover 2, a vacuum one-way valve 3, a support 4, a support plate 5, a vertical rod 6, a connecting ring 7, a reinforcing rib 8, a rotating part 9, and a rubber sealing ring 10.

[0028] The storage box body 1 is a hollow cylinder made of high-strength ABS material. The upper end is open and the outer side wall is provided with external threads. The sealing cover 2 is a disc-shaped structure with internal threads on the inner side wall that are compatible with the storage box body 1. The sealing is achieved through threaded connection.

[0029] In detail, the bottom center of the storage box body 1 and the top center of the sealing cover 2 are both recessed inward to form a concave part. The upper concave part, i.e. the top of the sealing cover 2, is embedded with a vacuum one-way valve 3. The vacuum one-way valve 3 is connected to the inside of the storage box body 1 and can be vacuumed by external air extraction equipment to prevent air backflow.

[0030] In actual setup, the threaded connection between the storage box body 1 and the sealing cover 2 ensures a tight connection and facilitates manual opening and closing. Combined with the elastic compression of the rubber sealing ring 10, a double seal can be formed between the box body and the cover, effectively preventing external moisture from intruding and solving the problem of easy failure of traditional single-layer structure seals.

[0031] More specifically, the support member 4 is vertically fixed to the inner bottom wall of the storage box body 1. It is columnar in shape with a regular hexagonal cross-section at the top. All six sides are tightly fitted to the inner wall of the storage box body 1. The support plate 5 consists of six rectangular metal plates, which are respectively set between the six sides of the support member 4 and the inner wall of the storage box body 1. The length of the rectangular plates is set along the radial direction of the storage box body 1. Together with the storage box body 1 and the support member 4, they form a stable support system.

[0032] In actual setup, the support plate 5 is a rectangular plate structure. One side of the support plate 5 is fixedly connected to one side of the support member 4, and the other side is fixedly connected to the inner wall of the storage box body 1. This allows the support plate 5 to form a stable triangular support structure by enclosing the corresponding side of the support member 4 and the inner wall of the storage box body 1. Since the triangular structure has extremely strong stability, this combination method can effectively transfer the external pressure that the storage box body 1 bears under negative pressure environment to the support member 4 through the support plate 5. Then, the hexagonal structure of the support member 4 distributes the pressure to multiple stress points, thereby forming a multi-directional and uniform support force on the storage box body 1.

[0033] In addition, there are seven cylindrical plastic rods 6, which are vertically installed on the bottom wall of the storage box body 1. One of them is located at the center of the bottom wall of the storage box body 1, and the other six are arranged in a ring array on the outside of the central rod 6 with equal spacing, for mounting the 3D printing consumable coil.

[0034] In actual setup, the distribution design of the seven uprights 6 can store multiple consumable coils at the same time. The central upright 6 and the outer uprights 6 of the ring array form a classified storage space to avoid wire tangling.

[0035] Furthermore, a connecting ring 7 is fixed inside each of the two concave portions. Six radially distributed reinforcing ribs 8 are welded between the connecting ring 7 and the inner peripheral wall of the concave portion. The rotating part 9 is a regular hexagonal plastic ring, which is fitted on the middle of the outer side of the storage box body 1 and fixed to the box body, making it easy to rotate by hand to open and close the sealing cover 2. The rubber sealing ring 10 is annular and embedded in the inner side of the lower edge of the sealing cover 2. When the sealing cover 2 is tightened, the sealing ring is tightly fitted to the upper end face of the storage box body 1 to enhance the sealing performance.

[0036] In actual setup, the combination of connecting ring 7 and reinforcing rib 8 enhances the structural strength of the bottom of the storage box body and the inner recess of the top of the sealing cover, preventing these weak areas from deforming due to the pressure difference between the inside and outside during vacuuming; the radial distribution of reinforcing rib 8 can evenly disperse the pressure, balance the force on the inner recess, and extend the service life of the box.

[0037] In addition, the hexagonal rotating part 9 increases the friction between the hand and the box, making it easier for operators to quickly tighten or loosen the sealing cover 2. It can still be operated stably, especially when the surface of the box is wet or the hands are oily, thus improving the ease of use.

[0038] It should be noted that the vacuum check valve 3 in this embodiment adopts the same working principle as the vacuum check valve on the vacuum bag in the prior art. It has a movable valve plate structure inside. When it is necessary to open the sealing cover 2, the valve plate on the vacuum check valve 3 can be manually operated to make the valve plate overcome the elastic force and suction force and tilt upward, thereby opening the airflow channel between the inside of the storage box body 1 and the outside. At this time, the outside air flows into the storage box body 1 through the gap of the tilted valve plate under the action of atmospheric pressure, gradually balancing the negative pressure state inside the box. When the air pressure inside the box is close to the outside atmospheric pressure, the pressure difference between the sealing cover 2 and the storage box body 1 disappears. The operator can easily rotate the sealing cover 2 to open and close it, avoiding the problem that the sealing cover 2 is difficult to open due to excessive negative pressure inside the box, and improving the convenience of operation.

[0039] The working principle of the above embodiments is as follows:

[0040] (1) Place the 3D printing consumable coils on the seven uprights 6 respectively. After placement, embed the rubber sealing ring 10 into the edge of the sealing cover 2. Hold the rotating part 9 and align the sealing cover 2 with the upper surface of the storage box body 1. Rotate clockwise until tightened. At this time, the sealing ring is compressed to form a preliminary seal. Connect the interface of the external air extraction device to the vacuum one-way valve 3. Start the device to extract the air inside the storage box body 1, so that a negative pressure environment is formed inside the box. During the air extraction process, the storage box body 1 is subjected to the radial pressure of the external atmospheric pressure. The hexagonal structure of the support part 4 transmits the pressure to the inner wall of the box through the six corners. The rectangular plate-shaped support plate 5 distributes the pressure evenly to all parts of the box with its own structure to prevent the box from deforming. The reinforcing rib 8 in the concave part resists the axial pressure and avoids the bottom and top from sinking. After the preset vacuum degree is reached, turn off the air extraction device and disconnect the interface. The vacuum one-way valve 3 closes automatically to maintain the vacuum state inside the box.

[0041] (2) When it is necessary to open, the valve plate on the vacuum one-way valve 3 is manually operated to make the valve plate overcome the elastic force and suction force and tilt upward, thereby opening the airflow channel between the inside of the storage box body 1 and the outside. At this time, the outside air flows into the inside of the storage box body 1 through the gap of the tilted valve plate under the action of atmospheric pressure, gradually balancing the negative pressure state inside the box. When the air pressure inside the box is consistent with the outside atmospheric pressure, the pressure difference between the sealing cover 2 and the storage box body 1 disappears, and the operator can easily rotate the sealing cover 2 to open and close, avoiding the problem that the sealing cover 2 is difficult to open due to excessive negative pressure inside the box, and improving the convenience of operation.
