Description

Technical Field

[0001] This application relates to the field of 3D printer technology, specifically to a consumable storage device and a 3D printing system. Background Technology

[0002] The dryness of 3D printing filaments directly affects the quality of 3D printing; therefore, drying 3D printing filaments is necessary. Existing filament drying boxes generally include a sealed box body for holding the filament tray, preventing the entry of humid air from outside. An airflow channel is provided within the sealed box body, and a heating device and an exhaust device are installed at the air inlet of the airflow channel. The heating device heats the space inside the box to achieve dehumidification, and the exhaust device circulates air from the space inside the box back into the airflow channel for heating, further ensuring the filaments inside the sealed box remain dry. However, existing filament drying boxes, which use a combination of heating and exhaust devices within a sealed box, primarily create internal circulation. Humid air may still remain inside the sealed box, failing to create effective air convection and resulting in poor drying of the filaments.

[0037] Example:

[0038] Firstly, this application provides a consumable storage device for storing and drying printing consumables used in a 3D printer. See also... Figures 1 to 4 As shown, it includes a housing 1 with a accommodating chamber 11, a fan 2 disposed in the accommodating chamber 11, a heating assembly 3, and an exhaust fan 4 disposed on the housing 1. The fan 2 is used to blow air in the housing 1, the heating assembly 3 is used to heat the air in the accommodating chamber 11, and the exhaust fan 4 is used to exhaust air in the housing 1. An exhaust port 12 is provided on the area of ​​the housing 1 corresponding to the exhaust fan 4. The consumable storage device described in this application includes a fan 2, a heating component 3, and an exhaust fan 4 disposed within the accommodating chamber 11. In use, the exhaust fan 4 exhausts air from the housing 1, the heating component 3 heats the air within the accommodating chamber 11 to prevent humid air from affecting the consumables, and the fan 2 accelerates airflow while simultaneously directing air towards the exhaust fan 4, increasing its exhaust speed. The consumable storage device, through the combined action of the exhaust fan 4, the heating component 3, and the fan 2, forms an effective air convection channel, ensuring the drying of consumables stored in the accommodating chamber 11 while simultaneously allowing effective airflow within the device, expelling humid air trapped within the housing 1, thereby improving the drying effect on the consumables. The consumable transfer device described in this application can dry consumables during routine storage or during 3D printing. The housing 1 can be considered a sealed housing.

[0039] Optionally, the fan 2 and the heating component 3 are located at the bottom of the receiving chamber 11, and the exhaust fan 4 is located at the top or side of the receiving chamber 11. Positioning the fan 2 and the heating component 3 at the bottom of the receiving chamber 11 avoids interference with the handling of consumables. Simultaneously, the combined action of the fan 2 and the heating component 3 prevents the accumulation of humid air at the bottom of the receiving chamber 11. The exhaust fan 4 effectively removes humid air from the receiving chamber 11, preventing the consumables from being corroded by humid air. The arrangement of the fan 2, the heating component 3, and the exhaust fan 4 improves the overall structural rationality of the consumable storage device. Specifically, in some embodiments, when the exhaust fan 4 is located at the top of the accommodating chamber 11, the exhaust fan 4 may be located in the area of ​​the housing 1 corresponding to the accommodating chamber 11; when the exhaust fan 4 is located on the side of the accommodating chamber 11, the exhaust fan 4 may be located on the side wall panel of the housing 1.

[0040] Optional, see Figures 4 to 6As shown, the consumable storage device further includes a consumable support mechanism 5 disposed within the receiving chamber 11. The consumable support mechanism 5 includes a first rotating shaft assembly 51 and a second rotating shaft assembly 52, which are spaced apart from each other. When the consumable tray 10 is received within the receiving chamber 11, the consumable tray 10 is supported by the first rotating shaft assembly 51 and the second rotating shaft assembly 52 respectively. See also Figure 7 As shown, the air duct formed by the fan 2, the heating component 3, and the exhaust fan 4 surrounds at least a portion of the periphery of the consumable material tray 10. In use, the consumable material tray, containing the consumable material, is supported by the first rotating shaft assembly 51 and the second rotating shaft assembly 52. ​​When the consumable material is pulled, the first rotating shaft assembly 51 and the second rotating shaft assembly 52 rotate synchronously with the consumable material tray, assisting in the rotation of the tray and improving the smoothness of consumable material transport. In some embodiments, the first rotating shaft assembly 51 and the second rotating shaft assembly 52 are respectively connected to the inner wall of the receiving chamber 11. The first rotating shaft assembly 51 and the second rotating shaft assembly 52 each include a rotating shaft 511 coaxially arranged with the consumable material tray and a first mounting seat 512 disposed at both ends of the rotating shaft 511. The first mounting seat 512 is disposed on the inner wall of the receiving chamber 11, and the two ends of the rotating shaft 511 are rotatably connected to the first mounting seat 512. When consumable materials are discharged from the consumable material storage device, the consumable material tray rotates, driving the rotating shaft 511 in contact with the consumable material tray to rotate, thereby assisting the rotation of the consumable material tray. In other embodiments, at least one of the first rotating shaft assembly 51 and the second rotating shaft assembly 52 further includes a rotation drive, and the rotating shaft 511 is connected to the output end of the rotation drive; when the consumable is discharged from the consumable storage device, the rotating shaft 511 rotates under the drive of the rotating shaft 511 drive to provide driving force for the rotation of the consumable material disk, thereby compensating for the insufficient extrusion power of the extrusion mechanism in the 3D printing system.

[0041] When the consumable material tray 10 is located in the accommodating chamber 11, the heating component 3 can dry the consumable material tray 10 on which the consumable material is installed. Specifically, the heating component 3 can heat the air around the consumable material tray 10 to avoid the humid air from having an adverse effect on the consumable material wound on the consumable material tray 10 and to avoid affecting the printing quality.

[0042] Optionally, a partition 6 is provided at the bottom of the accommodating chamber 11, and a consumable placement cavity 111 for placing consumables is formed between the partition 6 and the housing 1. The fan 2 and the heating assembly 3 are spaced apart below the partition 6, and the exhaust fan 4 is located at the top or side of the consumable placement cavity 111. A vent hole 61 is provided on the partition 6. The first rotating shaft assembly 51 and the second rotating shaft assembly 52 are located above the partition 6.

[0043] The partition 6 separates the upper and lower areas of the accommodating chamber 11, and centrally houses the fan 2 and the heating component 3 within the space formed by the partition 6 and the housing 1, thereby improving the overall integration of the consumable storage device. During use, consumables are placed in the consumable placement cavity 111, separating them from the fan 2 and the heating component 3, thus preventing interference from the fan 2 and the heating component 3 in the transmission of consumables. Furthermore, the vent 61 ensures smooth airflow within the accommodating chamber 11, preventing moisture accumulation.

[0044] Optionally, the partition 6 is at least partially an arc-shaped curved surface structure 64 recessed towards the bottom surface of the housing 1. The fan 2 and the heating component 3 are respectively disposed between the arc-shaped curved surface structure 64 and the bottom surface of the housing 1, and the fan 2 and the heating component 3 are respectively located at opposite ends of the arc-shaped curved surface structure 64. The arc-shaped curved surface structure 64 is designed to conform to the shape of the tray for winding consumables, which facilitates the placement of consumables and makes full use of the space of the device. A drying box 62 is provided on the side of the arc-shaped curved surface structure 64 facing the bottom surface of the housing 1. The drying box 62 is configured to hold a desiccant 63. The drying box 62 is at least partially disposed between the fan 2 and the heating component 3. The drying box 62 uses desiccant 63 to absorb humid air in the accommodating chamber 11, further improving the drying effect on consumables. Furthermore, the drying box 62 is positioned between the fan 2 and the heating component 3. When the fan 2 blows air through the accommodating chamber 11, the moisture absorbed by the desiccant 63 flows with the air and is heated by the heating component 3 or directly discharged by the exhaust fan 4. Optionally, the desiccant 63 can be a reusable activated alumina desiccant. Optionally, the arc-shaped curved surface structure 64 on the partition 6 can be specifically configured according to actual needs. When the partition 6 is positioned close to the fan 2 and the heating component 3, the areas of the partition 6 close to the fan 2 and the heating component 3 are planar, facilitating the installation of the fan 2 and the heating component 3 while ensuring efficient use of space in the device, which is beneficial for miniaturization design. The number of rolls of consumables that the accommodating chamber 11 can hold is at least one; when the accommodating chamber 11 contains two rolls of consumables, the number of rotating shafts 511 in the first rotating shaft assembly 51 and the second rotating shaft assembly 52 can be one or correspond one-to-one with the consumables; when the rotating shafts 511 correspond one-to-one with the consumables, the arc-shaped curved surface structure 64 is provided with a second mounting seat 513 to enable the rotating shafts 511 to rotate smoothly.

[0045] See Figure 5 As shown, the exhaust fan 4 has a one-way valve 9 at its outlet. In use, when the exhaust fan 4 is off, the one-way valve 9 is closed to keep the inside of the housing 1 sealed, isolating it from external air and preventing outside air from entering the housing 1 through the exhaust fan 4; when the exhaust fan 4 is working, the one-way valve 9 is open to expel internal moisture.

[0046] See Figures 1 to 4 As shown, the housing 1 includes a bottom shell 13 and an upper cover 14 that is fitted and connected to the bottom shell 13. The upper cover 14 is fitted and connected to the bottom shell 13 via a flip assembly 15. The opening and closing end of the upper cover 14 is connected to the bottom shell 13 via a locking assembly 16. The exhaust fan 4 is disposed on the bottom shell 13 and is located near the flip assembly 15. The fan 2 is located on the side near the locking assembly 16. The heating assembly 3 is located on the side near the flip assembly 15. See also Figure 2 As shown, the flipping assembly 15 includes a first connecting block 151 disposed on the bottom shell 13, a second connecting block 152 disposed on the upper cover 14, and a connecting rod 153 respectively passing through the first connecting block 151 and the second connecting block 152. The first connecting block 151 and the second connecting block 152 are provided with a first through hole and a second through hole coaxially arranged, and the connecting rod 153 is disposed within the first through hole and the second through hole. See also... Figure 8 and Figure 9 As shown, the locking assembly 16 is a sliding fastener assembly. The locking assembly 16 includes a first protrusion 161, a second protrusion 162, and a sliding fastener 163. The first protrusion 161 is located on the upper cover 14, and the second protrusion 162 is located on the bottom shell 13 and is embedded in the first protrusion 161. The first protrusion 161 and the second protrusion 162, when combined, form a guide protrusion structure for the sliding fastener 163 to move. The locking assembly is configured as a sliding fastener assembly, allowing for the opening and closing of the bottom shell 13 and the upper cover 14 through simple sliding and mechanical operation. When the housing 1 is closed, the snap fastener 163 moves toward the direction of the second protrusion 162. When the snap fastener 163 moves to the point where at least part of the second protrusion 162 is located within the projection area of ​​the snap fastener 163, the locking between the upper cover 14 and the bottom cover 13 can be completed. When the housing 1 is opened, the snap fastener 163 moves toward the direction of the second protrusion 162. When the snap fastener 163 moves to the point where the second protrusion 162 is fully exposed, the upper cover 14 can be opened.

[0047] Optionally, the upper cover 14 has a first discharge port 141, and the bottom shell 13 has a second discharge port 131. The arrangement of the first discharge port 141 and the second discharge port 131 makes the discharge of consumables more flexible and adaptable to more complex environments. In some embodiments, to improve the overall aesthetics of the consumable storage device, the second discharge port 131 is located on the same side of the bottom shell 13 as the flipping component 15. The first discharge port 141 and the second discharge port 131 are each provided with a sealing element 7. When consumables are being discharged, the sealing element 7 is opened; when no consumables are being transported, the sealing element 7 seals the first discharge port 141 and the second discharge port 131 to ensure the airtightness of the consumable storage device and prevent humid air from entering the receiving chamber 11 through the first discharge port 141 and / or the second discharge port 131. See also Figure 10 As shown, the sealing element 7 includes a sealing element body 71, positioning protrusions 72 respectively disposed at both ends of the sealing element body 71, and a sealing plug 73. The sealing element 7 is connected to the housing 1 through the positioning protrusions 72, and the sealing plug 73 can be inserted into the first discharge port 141 and the second discharge port 131.

[0048] Optionally, at least two accommodating chambers 11 are provided, with the upper cover 14 corresponding to each accommodating chamber 11, so that the consumable storage chambers can be operated independently, facilitating the storage, replacement, and retrieval of consumables, and enabling individual operation and control. The heating assembly 3 and the exhaust fan 4 are corresponding to each accommodating chamber 11, and the number of fans 2 is at least one. For example, see... Figure 11 As shown, in some embodiments, the number of accommodating chambers 11 is two, with the heating assembly 3 and the exhaust fan 4 corresponding one-to-one with each accommodating chamber 11; the number of fans 2 is one, meaning that the accommodating chambers 11 share one fan 2, and each fan 2 is connected to one of the accommodating chambers 11. In use, the fan 2 blows air, causing the air to split into two paths and move towards the heating assembly 3 respectively. This structure reduces the number of fans 2 and simplifies the overall structure of the consumable storage device. In other embodiments, see... Figure 12 As shown, the fan 2, heating component 3 and exhaust fan 4 are all arranged in a one-to-one correspondence with the accommodating chamber 11. This structure can further realize individual control of the air conditions in each accommodating chamber 11 and improve the drying efficiency of consumables.

[0049] Optionally, a display screen 8 is provided on the bottom shell 13, and the display screen 8 is disposed on the same side as the locking assembly 16.

The temperature and humidity sensor is electrically connected to the display screen 8, the fan 2, the heating assembly 3, and the exhaust fan 4. The display screen 8 is used to display the parameter information detected by the temperature and humidity sensor. The fan 2, the heating assembly 3, and the exhaust fan 4 can adjust the temperature and humidity inside the consumable storage device according to the parameter information detected by the temperature and humidity sensor to ensure that the consumables are in a dry state and to ensure the effect of 3D printing. Specifically, in some embodiments, a temperature and humidity sensor is provided in each of the accommodating chambers 11, which can realize the individual and accurate adjustment of the temperature, humidity, and other conditions in each of the accommodating chambers 11.

[0050] See Figure 13 As shown, the heating assembly 3 includes spaced-apart heat-conducting plates 31, ceramic heating plates 32 disposed between the gaps of the heat-conducting plates 31, and a fuse 33 electrically connected to the ceramic heating plates 32. In use, the ceramic heating plates 32 generate heat, which is transferred to the heat-conducting plates 31, causing the heat-conducting plates 31 to heat the air passing through the heating assembly 3. The heat-conducting plates 31 are bent into several fin-like shapes, increasing the contact area with air and improving the heating efficiency of the heating assembly 3.

[0051] Secondly, this application provides a 3D printing system, which includes a filament extruder and a filament storage device as described above. The filament storage device is connected to the filament extruder and is used to store printing filaments. The filament is wound into a filament tray 10 and placed inside the filament storage device. When printing material using the 3D printing system of this application, the filament extruder is started, and the filament is output from the filament storage device. During use, the fan 2 blows the air in the accommodating chamber 11 toward the heating component 3, which heats the humid air. The exhaust fan 4 draws in air and exhausts the air in the accommodating chamber 11. The fan 2, the component, and the exhaust fan 4 work together to form an effective air convection channel, improving the drying efficiency of the filament stored in the filament storage device and improving the printing quality of the 3D printing system.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
