Abstract

This utility model discloses a consumable conveying device and a 3D printer. It primarily utilizes a power component that selectively connects and disconnects from the ejector component. During feeding, the power component does not actively move the material tray; during ejection, the power component drives the material tray to actively rotate and rewind the consumable. This eliminates the need for a separate power mechanism for the material tray, simplifying the structure and reducing control complexity. The main technical solution of this utility model is as follows: a consumable conveying device includes a feeding component, which is connected to the consumable; an ejector component, which is connected to the material tray; a power component; and a one-way transmission component, located between the power component and the ejector component. During feeding, the power component is connected to the feeding component, and the one-way transmission component is in a disengaged state, thus separating the power component from the ejector component. During ejection, the one-way transmission component is in a connected state, thus connecting the power component to the ejector component. This utility model is mainly used for consumable conveying.

Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a consumables transfer device and a 3D printer. Background Technology

[0002] In FDM printers, filament is fed in filament form. After passing through the extrusion mechanism, the filament is introduced into the printhead. During feeding, the extruder pushes the filament into the printhead, and the filament pulls on the reel, causing it to rotate passively to release the filament. During unloading, the extruder moves the filament in the opposite direction to remove it from the printhead. To prevent filament buildup, the reel is usually driven to rotate actively to rewind the filament.

[0003] In existing technologies, two sets of drive mechanisms are typically used. One set of drive mechanisms moves the consumable material to achieve feeding, while the other set of drive mechanisms moves the material tray during unloading to achieve rewinding of the consumable material. This method involves a large number of drive mechanisms, occupies a lot of space, is costly, and requires separate control of each drive mechanism. Utility Model Content

[0004] In view of this, in order to solve at least one of the above-mentioned technical problems, this utility model provides a consumables transfer device and a 3D printer.

[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0006] On the one hand, this utility model provides a consumables transmission device, comprising:

[0007] The feeding assembly is connected to the consumable drive.

[0008] The unloading assembly is connected to the material tray drive.

[0009] Power components;

[0010] A one-way transmission component is located between the power assembly and the unloading assembly. During feeding, the power assembly and the feeding assembly are connected, and the one-way transmission component is in a disengaged state, thus separating the power assembly from the unloading assembly. During unloading, the one-way transmission component is in a connected state, thus connecting the power assembly to the unloading assembly.

[0011] The unloading assembly and the power assembly are connected by a one-way transmission component.

[0012] During feeding, the power component drives the one-way transmission component to be in a disengaged state, thus separating the power component from the unloading component; during unloading, the power component drives the one-way transmission component to be in a connected state, thus connecting the power component with the unloading component to drive the material tray to rotate and rewind the consumable.

[0013] Among them, the unloading component and the feeding component are connected by a one-way transmission component, and the power component is connected to the feeding component by a transmission.

[0014] During feeding, the power unit drives the feeding component to feed, and the feeding component drives the one-way transmission component to be in a transmission disengagement state, so that the feeding component and the unloading component are transmission disengaged. During unloading, the power unit drives the feeding component to unload, and the feeding component drives the one-way transmission component to be in a transmission connection state, so that the feeding component and the unloading component are in a transmission connection state. The feeding component drives the unloading component to move, so as to drive the material tray to rotate and rewind the consumable.

[0015] The feeding assembly includes a passive extruder and an active extruder assembly, with the active extruder assembly and the passive extruder assembly used to allow the consumable to pass through.

[0016] The active extrusion assembly and the unloading assembly are connected by a one-way transmission component, and the power assembly is connected to the active extrusion assembly via a transmission connection.

[0017] During feeding, the power unit drives the active extrusion unit to feed, and the active extrusion unit drives the one-way transmission component to be in a transmission disengagement state, so that the active extrusion unit and the unloading unit are transmission disengaged. During unloading, the power unit drives the active extrusion unit to unload, and the active extrusion unit drives the one-way transmission component to be in a transmission connection state, so that the active extrusion unit and the unloading unit are in a transmission connection state, so that the active extrusion unit drives the unloading unit to move, thereby driving the material tray to rotate and rewind the consumables.

[0018] The unloading assembly includes a first action member, which is connected to a one-way transmission member and is connected to the rim of the material tray. During unloading, the one-way transmission member drives the first action member to rotate synchronously, thereby driving the material tray to rewind the consumables.

[0019] or,

[0020] The unloading assembly includes a transmission assembly and a first action member. The transmission assembly is connected to a one-way transmission member, and the first action member is connected to the transmission assembly in a transmission manner. The first action member is used for transmission connection with the rim of the material tray. During unloading, the one-way transmission member drives the transmission assembly to move, which in turn drives the first action member to rotate so as to drive the material tray to rewind the consumables.

[0021] The transmission assembly includes a first gear and a second gear;

[0022] The first working element includes an actuating shaft and a third gear. The third gear is mounted on the actuating shaft, which is used for transmission connection with the rim of the material tray.

[0023] The first gear is connected to the one-way transmission component, the second gear meshes with the first gear, and the second gear meshes with the third gear.

[0024] The second gear includes a first disk and a second disk. The first disk meshes with the first gear, and the second disk meshes with the third gear. The outer diameter of the second disk is larger than the outer diameter of the first disk.

[0025] The outer diameter of the first gear is larger than the outer diameter of the first disc.

[0026] The first functional component includes an action shaft and a third gear. The action shaft includes an abutment part and a shaft center. The third gear is connected to the shaft center and is used to connect with the transmission assembly. Abutment parts are provided on both sides of the third gear, and the two abutment parts are respectively connected to the two end plates of the material tray for transmission.

[0027] The one-way transmission component includes a one-way bearing or a ratchet, and the one-way transmission component is coaxially arranged with the feeding assembly.

[0028] The feeding assembly includes a passive extruder and an active extrusion assembly;

[0029] The active extrusion assembly includes an active extruder, a feed wheel shaft, and a transmission component, both of which are connected to the feed wheel shaft.

[0030] The active extruder is used in conjunction with the passive extruder to clamp consumables, and the transmission component is connected to the power assembly for transmission.

[0031] The active extruder includes a limiting groove that surrounds the active extruder and corresponds to the passive extruder. The limiting groove is used to accommodate a portion of the consumables.

[0032] The consumables transport device also includes:

[0033] The housing includes a receiving space, in which at least a portion of the structure of the feeding assembly, the unloading assembly, and the power assembly are located.

[0034] The consumable conveying device also includes a second action component. The material unloading assembly and the second action component are used to support the material tray from both sides of the bottom of the tray.

[0035] On the other hand, the present invention also provides a 3D printer, including the consumable transport device of any of the foregoing.

[0036] This invention discloses a filament conveying device and a 3D printer. It primarily utilizes a unidirectional transmission component. When feeding is required, a power component drives the feeding component to clamp and push the filament towards the print head. The unidirectional transmission component is in a disengaged state, separating the power component from the unloading component. This prevents the filament tray from actively rotating due to the power component's movement; the tray passively releases the filament only under its pull. During unloading, the unidirectional transmission component is in a connected state, connecting the power component to the unloading component. The power component then transmits power to the filament tray, driving it to rotate actively and thus actively rewinding the filament. By selectively connecting and disconnecting the power component from the unloading component, a single power component can drive both filament feeding and unloading, eliminating the need for a separate power mechanism for the filament tray and significantly simplifying the structure and control complexity.

[0041] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific optional implementation methods, structures, features and effects of the consumable transmission device proposed according to this utility model.

[0042] On the one hand, such as Figure 1-4 As shown, this utility model embodiment provides a consumables transmission device, including:

[0043] Feeding assembly 10 is connected to the consumable drive;

[0044] Unloading assembly 20 is connected to the material tray 700 via a transmission mechanism.

[0045] Power Components 600;

[0046] A one-way transmission component 300 is disposed between the power assembly 600 and the unloading assembly 20. During feeding, the power assembly 600 is connected to the feeding assembly 10, and the one-way transmission component 300 is in a disengaged state, thus disengaging the power assembly 600 from the unloading assembly 20. During unloading, the one-way transmission component 300 is in a connected state, thus connecting the power assembly 600 to the unloading assembly 20.

[0047] The consumables delivery device can be a standalone unit separate from the printer, with an overall box-like structure, located on one side of the printer. Consumables drawn from the delivery device are simply inserted into the printer's printhead. Alternatively, the consumables delivery device can be integrated into the printer, such as by connecting it to the top or side beams of the printer's gantry.

[0048] The feeding assembly 10 can transfer consumables in various ways, such as by clamping. The unloading assembly 20 can be connected to the tray 700 in various ways, including direct or indirect connection. The unloading assembly 20 can drive the tray 700 to rotate by rolling. For example, the tray 700 includes two end plates and a central connecting shaft. The two end plates are respectively disposed on both sides of the central connecting shaft, which is used to wind consumables, and the end plates are used to confine the consumables within it. The unloading assembly 20 can be connected to the tray 700 by abutment, such as by abutting against the rim of the tray 700 or the edge of the end plate; alternatively, the unloading assembly 20 can be coaxially connected to the tray 700, such as by coaxially connecting to the central connecting shaft.

[0049] During ejection, the power unit 600 can be connected to the feeding unit 10, thereby driving the feeding unit 10 to actively extract the consumable from the printhead, while the ejection unit 20 drives the material tray 700 to move and rewind the consumable removed by the feeding unit 10. Alternatively, during ejection, the power unit 600 and the feeding unit 10 can be disconnected, and the ejection unit 20 can drive the material tray 700 to move and rewind the consumable, thus achieving the extraction of the consumable from the printhead.

[0050] The power assembly 600 is disengaged from the unloading assembly 20 during feeding, but connected during unloading. This disengagement and connection refer to the disconnection and connection of power transmission. Specifically, during feeding, the power from the power assembly 600 is not transmitted to the unloading assembly 20, thus preventing the material tray 700 from moving actively due to the power from the power assembly 600. During unloading, however, the power from the power assembly 600 is transmitted to the unloading assembly 20, causing the unloading assembly 20 to follow the power assembly 600 and actively drive the material tray 700 to move and rewind. The connection and disengagement of the power assembly 600 and the unloading assembly 20 are achieved through the structure of the one-way transmission component 300. The one-way transmission component 300 can be a one-way rotating component. Depending on the driving direction of the power assembly 600's output during feeding and unloading, the transmission of rotational power is determined by the internal structure. For example, the one-way transmission component 300 can be a one-way bearing or a ratchet; various existing one-way bearings or ratchets can be selected.

[0051] Taking a one-way bearing as an example, the one-way bearing includes an outer ring, an inner ring, rollers, and springs. The outer ring is fitted around the outer circumference of the inner ring. The inner ring has multiple circumferentially arranged guide ramps and cross-sections connecting with the guide ramps. The rollers are connected to the end faces by springs and are positioned between the guide ramps and the outer ring. The inner ring is directly or indirectly connected to the power component 600, and the outer ring is connected to the ejector component 20. During feeding, the power component 600 directly or indirectly drives the inner ring to move forward. The forward movement of the inner ring drives the springs to push the rollers to move. Then, through the spring action, the rollers tend to move towards the side with more space between the guide ramps and the outer ring, preventing the rollers from jamming. Consequently, the inner ring will rotate relative to the outer ring without driving the outer ring to move. At this time, the one-way transmission component 300 is in a disengaged state, ensuring that the ejector component 20 is not actively moved by the power component 600 during feeding. During unloading, the power component 600 directly or indirectly drives the inner ring to move in the opposite direction. This reverse movement of the inner ring causes the spring to pull the roller, which tends to move towards the side with less space between the guide ramp and the outer ring. The roller is then clamped by the guide ramp and the outer ring, preventing the inner ring from spinning relative to the outer ring. Instead, it drives the outer ring to move synchronously. At this time, the one-way transmission component 300 is in a transmission connection state. When unloading, the unloading component 20 is driven by the power component 600 to move actively, which in turn drives the material tray 700 to move and rewind. Of course, other one-way bearings or ratchet structures can also be used, which have different structures but similar principles and serve the same function in transmission separation and connection.

[0052] This invention discloses a filament conveying device and a 3D printer. It primarily utilizes a unidirectional transmission component. When feeding is required, a power component drives the feeding component to clamp and push the filament towards the print head. The unidirectional transmission component is in a disengaged state, separating the power component from the ejection component. This prevents the filament tray from actively rotating due to the power component's movement; the tray passively releases the filament only under its pull. During ejection, the unidirectional transmission component is in a connected state, connecting the power component to the ejection component. The power component then transmits power to the filament tray, driving it to rotate actively and thus actively rewinding the filament. By selectively connecting and disconnecting the power component from the ejection component, a separate power mechanism for the filament tray is eliminated, significantly simplifying the structure and control complexity.

[0053] A one-way transmission component 300 is disposed between the power assembly 600 and the unloading assembly 20. The one-way transmission component 300 and the power assembly 600 can be directly connected. The switching between the transmission connection state and the transmission disengagement state of the one-way transmission component 300 is achieved by driving the power assembly 600. Alternatively, in some embodiments, the one-way transmission component 300 and the power assembly 600 can be indirectly connected, such as through the feeding assembly 10, which allows for a more flexible and compact structural arrangement. Examples of both embodiments will be provided below:

[0054] Firstly, the unloading assembly 20 and the power assembly 600 are connected via a one-way transmission component 300. During feeding, the power assembly 600 drives the one-way transmission component 300 to a disengaged state, thus separating the power assembly 600 from the unloading assembly 20; during unloading, the power assembly 600 drives the one-way transmission component 300 to a connected state, thus connecting the power assembly 600 to the unloading assembly 20, thereby driving the material tray 700 to rotate and rewind the consumables.

[0055] That is, the output end of the power component 600 is directly connected to the one-way transmission component 300. The one-way transmission component 300 is driven to switch between the transmission connection state and the transmission separation state by the forward and reverse rotation of the output end of the power component 600.

[0056] Secondly, the unloading assembly 20 and the feeding assembly 10 are connected via a one-way transmission component 300, and the feeding assembly 10 is connected to the power assembly 600 via a transmission connection. During feeding, the power assembly 600 drives the feeding assembly 10 to feed, and the feeding assembly 10 drives the one-way transmission component 300 in a transmission disengagement state, thus disengaging the feeding assembly 10 from the unloading assembly 20 via a transmission connection, and consequently disengaging the power assembly 600 from the unloading assembly via a power connection. During unloading, the power assembly 600 drives the feeding assembly 10 to unload, and the feeding assembly 10 drives the one-way transmission component 300 in a transmission connection state, thus connecting the feeding assembly 10 to the unloading assembly 20 via a transmission connection. The feeding assembly 10 drives the unloading assembly 20 to move, thereby driving the material tray 700 to rotate and rewind the consumables.

[0057] That is, the feeding assembly 10 is connected to the one-way transmission component 300. The one-way transmission component 300 is driven to switch between the transmission connection state and the transmission separation state by the different moving directions of the feeding assembly 10 during feeding and unloading.

[0058] The feeding assembly 10 can be implemented in various ways. Taking the following embodiment as an example, the feeding assembly 10 includes a passive extruder 100 and an active extrusion assembly 200. The active extrusion assembly 200 and the passive extruder 100 are used to allow the consumable to pass through. The passive extruder 100 and the active extrusion assembly 200 cooperate to clamp the consumable from both sides. The active extrusion assembly 200 is used to move actively under the drive of the power assembly 600. Through the extrusion force on the consumable, it forces the passive extruder 100 to roll synchronously, thereby achieving smooth transmission of the consumable.

[0059] The active extrusion assembly 200 and the unloading assembly 20 are connected via a one-way transmission component 300, and the power assembly 600 is drive-connected to the active extrusion assembly 200. During feeding, the power assembly 600 drives the active extrusion assembly 200 to feed, and the active extrusion assembly 200 drives the one-way transmission component 300 to be in a disengaged state, thus disengaging the active extrusion assembly 200 from the unloading assembly 20. During unloading, the power assembly 600 drives the active extrusion assembly 200 to unload, and the active extrusion assembly 200 drives the one-way transmission component 300 to be in a drive-connected state, thus connecting the active extrusion assembly 200 to the unloading assembly 20. This causes the active extrusion assembly 200 to move the unloading assembly 20, thereby driving the material tray 700 to rotate and rewind the consumables.

[0060] When the active extrusion assembly 200 is feeding material, its direction of movement causes the one-way transmission component 300 to be in a disengaged state. The rotation of the active extrusion assembly 200 does not affect the movement of the unloading assembly 20, and no power is transmitted to the unloading assembly 20. However, when the active extrusion assembly 200 is unloading material, its direction of movement causes the one-way transmission component 300 to be in a connected state. The active extrusion assembly 200 will drive the portion connecting the unloading assembly 20 and the one-way transmission component 300 to move synchronously, thereby transmitting power to the material tray 700, which in turn enables the active movement of the material tray 700.

[0061] In embodiments where the one-way drive component 300 is connected to the feeding assembly 10 or the active extrusion assembly 200, the one-way drive component 300 and the active extrusion assembly 200 are coaxially arranged. In embodiments where the one-way drive component 300 is directly connected to the power assembly 600, the one-way drive component 300 and the output end of the power assembly 600 are coaxially arranged. This reduces design complexity and saves installation space.

[0062] In one embodiment, the unloading assembly 20 includes a first actuating member 500, which is connected to a one-way transmission member 300 and is connected to the rim of the material tray 700. During unloading, the one-way transmission member 300 drives the first actuating member 500 to move, thereby driving the material tray 700 to rotate and rewind the consumable.

[0063] The first actuating element 500 can be a roller, which frictionally abuts against the end plate, moving synchronously or nearly synchronously. During feeding, the power unit 600 or the active extrusion unit 200 rotates upwards, while the one-way transmission component 300 is in a disengaged state and does not drive the first actuating element 500 to rotate. The material tray 700 rotates under the pull of the consumable material to release it. During unloading, the power unit 600 or the active extrusion unit 200 rotates in the opposite direction, while the one-way transmission component 300 is in a connected state. Under the one-way transmission action of the one-way transmission component 300, the first actuating element 500 rotates. Simultaneously with unloading, the material tray 700 rewinds the consumable material, preventing consumable material accumulation.

[0064] In another embodiment, the unloading assembly 20 includes a transmission assembly 400 and a first actuating member 500. The first actuating member 500 is connected to the transmission assembly 400 and is used to drive the rim of the material tray 700. The transmission assembly 400 is connected to a one-way transmission member 300. When unloading, the one-way transmission member 300 drives the transmission assembly 400 to move, thereby driving the first actuating member 500 to rotate the material tray 700 to rewind the consumables.

[0065] The transmission assembly 400 may include one or more gears. By setting the transmission assembly 400, on the one hand, the relationship between the angular velocity of the first action member 500 and the angular velocity of the output end of the power assembly 600 can be changed by setting the size of the gears, thereby adjusting the rotational speed of the unloading assembly 20 or the first action member 500 during unloading, and thus adjusting the speed at which the material tray 700 rewinds the consumables; on the other hand, the setting position of the power assembly 600 can be changed, so that space can be used more rationally.

[0066] The transmission assembly 400 can take various forms. For example, in both embodiments where the aforementioned one-way transmission member 300 is directly connected to the power assembly 600, or indirectly connected to the power assembly 600 via the active extrusion assembly 200, the following configuration can be used: The transmission assembly 400 includes a first gear 410 and a second gear 420. The first actuating member 500 includes an actuating shaft and a third gear 510, the third gear 510 being mounted on the actuating shaft, which is used for transmission connection with the rim of the material tray 700. The first gear 410 is connected to the one-way transmission member 300, the second gear 420 meshes with the first gear 410, and the second gear 420 meshes with the third gear 510.

[0067] The actuating shaft and the end plate rub against each other, moving synchronously or nearly synchronously. The first actuating element 500 and the active extrusion assembly 200 are arranged side by side with intervals, the first gear 410 is coaxially arranged with the active extrusion assembly 200, and the one-way transmission element 300 is arranged between the first gear 410 and the active extrusion assembly 200. Alternatively, the one-way transmission element 300 is arranged between the first gear 410 and the power assembly 600. Taking the one-way transmission element 300 connected to the power assembly 600 as an example, during feeding, the active extrusion assembly 200 rotates in the first direction (for example, if the power assembly is a motor, the motor's forward rotation drives the active extrusion assembly to rotate in the first direction), and the one-way transmission element 300 does not transmit power. Under the pull of the consumable, the material tray 700 rotates to release the consumable. During material unloading, the active extrusion component 200 rotates in the second direction (for example, the power component is a motor, and the motor reverses to drive the active extrusion component to rotate in the second direction). Under the unidirectional transmission action of the unidirectional transmission component 300, the first gear 410 is driven to rotate in the second direction. Through the transmission of the second gear 420 and the third gear 510, the action shaft is driven to rotate in the second direction. At the same time as material unloading, the material tray 700 rewinds the consumables, and there will be no accumulation of consumables.

[0068] In one embodiment, the second gear 420 includes a first disk 421 and a second disk 422. The first disk 421 meshes with the first gear 410, and the second disk 422 meshes with the third gear 510. The outer diameter of the second disk 422 is larger than the outer diameter of the first disk 421. The outer diameter of the first gear 410 is larger than the outer diameter of the first disk 421. This allows the first actuating member 500 to obtain a greater linear velocity, and during material unloading, the material tray 700 rotates faster, enabling faster rewinding of consumables.

[0069] In one embodiment, the first actuating member 500 includes an actuating shaft and a third gear 510. The actuating shaft includes an abutment portion 520 and a shaft center. The third gear 510 is connected to the shaft center and is used to connect with the transmission assembly 400. Abutment portions 520 are respectively provided on both sides of the third gear 510, and the two abutment portions 520 are used to connect with the two end plates of the material tray 700 respectively.

[0070] The contact part 520 can be made of a material with a certain degree of flexibility and high friction, such as rubber. The third gear 510 is located in the middle of the two contact parts 520, so that the force on the first action member 500 is balanced, and the two contact parts 520 also increase the friction, reducing the slippage of the material tray 700.

[0071] In one embodiment, the active extrusion assembly 200 includes an active extruder 210, a feed wheel shaft 220, and a transmission component 230. Both the active extruder 210 and the transmission component 230 are connected to the feed wheel shaft 220. The active extruder 210 cooperates with the passive extruder 100 to clamp consumables, and the transmission component 230 is drive-connected to the power assembly 600. The feed wheel shaft 220 is connected to the unidirectional transmission component 300. Figure 3 As shown, the one-way transmission component 300 can be coaxially arranged with the feed wheel shaft 220 to reduce the complexity of the structural design, save installation space, and effectively reduce production costs.

[0072] The active extruder 210 can be a D-shaped wheel, gear, etc. Alternatively, in one embodiment, the active extruder 210 includes a limiting groove 211, which surrounds the active extruder 210 and corresponds to the passive extruder 100. The limiting groove 211 is used to accommodate a portion of the consumable. The limiting groove 211 serves to limit the axial movement of the consumable within the active extruder 210, preventing the consumable from shifting and detaching from the passive extruder 100 and the active extruder 210. Extrusion teeth can be provided within the limiting groove 211, thereby increasing the friction between the active extruder 210 and the consumable and reducing slippage.

[0073] In one embodiment, the power assembly 600 includes a power element 610 and a worm gear 620, the worm gear 620 being connected to the output end of the power element 610 and being drivenly connected to the active extrusion assembly 200.

[0074] The transmission component 230 is a gear that meshes with the worm gear 620. By using the worm gear 620, the power component 610 can be positioned with its axis perpendicular to the active extrusion assembly 200, thus avoiding excessive axial space occupation by the active extrusion assembly 200 and making reasonable use of space.

[0075] The above-described embodiment using the worm gear 620 can be directly applied to embodiments where the one-way transmission component 300 is indirectly connected to the power component 600 via the feeding assembly 10. In embodiments where the one-way transmission component 300 is directly connected to the power component 600, an additional combination of a central gear and a central shaft can be provided. The central gear is connected to the central shaft, which is coaxially arranged with the active extrusion assembly 200. The central gear is connected to the central shaft and is also driven by the worm gear 620. The central shaft is connected to the unloading assembly 20 via the one-way transmission component 300, such as being connected to the first gear 410 via the one-way transmission component 300.

[0076] In one implementation, such as Figure 1-2 As shown, the consumables transfer device also includes a housing 800, which includes a receiving space in which at least a portion of the structure of the feeding assembly 10, the unloading assembly 20, and a portion of the structure of the power assembly 600 are located.

[0077] The housing 800 provides protection and support. For example, the feed wheel shaft 220 of the active extrusion assembly 200 can be connected to the housing 800 via bearings. The second gear 420 and the first actuating element 500 of the transmission assembly 400 can also be connected to the housing 800 via bearings.

[0080] On the other hand, this utility model also provides a 3D printer, including the filament transport device of any of the aforementioned components, and a printer body. The printer body includes an X-axis mechanism, a gantry mechanism, a base, and a printing platform. The gantry mechanism is mounted above the base, the printing platform is connected to the base, the X-axis mechanism is connected to the gantry mechanism, and the filament transport device is connected to the X-axis mechanism. The X-axis mechanism is used to drive the filament transport device to move in the X-axis direction, the gantry mechanism is used to drive the X-axis mechanism to move in the Z-axis (vertical direction), and the base is used to drive the printing platform to move in the Y-axis direction, thereby realizing the movement of the filament transport device relative to the printing platform in three dimensions, enabling stereoscopic printing. The filament transport device can be independent of the printer body, or it can be connected to the gantry mechanism, such as being mounted on the top beam of the gantry mechanism, the housing 800 being connected to the gantry mechanism, or the gantry mechanism being directly connected to the feeding assembly 10, the power assembly 600, and the ejection assembly 20, etc.

[0081] The 3D printer includes any of the aforementioned consumable transport devices, and the advantages of including any of the aforementioned consumable transport devices will not be elaborated here.

[0082] In one embodiment, the filament transport device has a heating and drying function. The filament transport device and the 3D printer each have independent power lines, meaning they can be powered independently. This ensures that while the 3D printer is printing a model, the filament transport device can perform both filament transport and heating / drying functions, preventing the filament transport device from exceeding its power limit when sharing the same power line, which would prevent the simultaneous drying and printing function from being achieved. The drying function in the simultaneous drying and printing process can be controlled independently, such as through a touchscreen or button on the box, a touchscreen or button on the printer, or remotely via a mobile phone or computer.
