[0001] The utility model relates to the technical field of 3D printing, in particular to a filament box and a 3D printer. Background Art
[0002] In an FDM printer, the filament is wound on a reel and extruded through an extruder to supply the print head with filament for spraying and three-dimensional molding.
[0003] In the prior art, in a color printer or a printer that can refill materials, when the filament needs to be replaced, the filament in the print head needs to be cut off, and then the extruder moves the filament in the opposite direction to withdraw the filament from the print head, and then the new filament is fed into the print head. The material tray is usually rewound at a speed equal to or slightly lower than the speed of the filament withdrawal to avoid pulling the filament, which will cause the filament to accumulate and easily overflow to the outside of the material tray, resulting in the filament being unable to be smoothly rewound onto the material tray, causing the filament to become tangled and jammed when feeding the material again. Utility Model Content

[0010] On the other hand, the utility model also provides a 3D printer, comprising any one of the filament boxes described above.
[0011] The utility model proposes a wire material box and a 3D printer, which mainly limit the position of the wire material by a guide member, so as to avoid the loose consumables between the transmission mechanism and the material tray, causing the consumables to overflow the material tray, and avoid the consumables from getting stuck and knotted.

[0020] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation method, structure, characteristics and effects of the wire material box proposed according to the utility model are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0021] On the one hand, if Figure 1-Figure 6 As shown, the embodiment of the utility model provides a wire material box, comprising:
[0022] The main body 100 includes a placement space, and the placement space is used to accommodate the material tray 10.
[0023] The transmission mechanism 200 is at least used to connect and move the wire 20 on the tray 10. In some embodiments, the transmission mechanism 200 can only transmit the wire 20 in two directions, forward and backward. In some embodiments, the transmission mechanism 200 can not only transmit the wire 20 in two directions, but also rotate the tray 10 where the wire 20 is located, so as to help the transmission of the wire 20 and reduce obstacles to the transmission of the wire 20 on the tray 10.
[0024] At least one guide member 300 includes a first end and a second end, the first end of the guide member 300 is opposite to the transmission mechanism 200, and at least a portion of the area extends toward the placement space in the direction from the first end to the second end. The guide member 300 is used to limit the position of the wire material 20.
[0025] The placement space refers to the space occupied by the material tray 10 when the silk material box is in use, or in other words, the space occupied by the material tray 10 after the material tray 10 is connected to the main body 100. The relative position relationship between the placement space and the main body 100 can be various, and the main body 100 can be of various shapes. For example, the placement space can be an internal space opened on the main body 100. For example, the main body 100 can be a box structure with a cavity, and the cavity is used to place the material tray 10, and the placement space is a partial area in the cavity. Alternatively, the placement space can also be an area outside the main body 100, such as the main body 100 is only used to support the material tray 10, such as supported by the bottom end of the material tray 10, or supported by the axis of the material tray 10, and the placement space is not the internal space of the main body 100, but is located entirely or partially outside the main body 100. Alternatively, when the main body 100 is connected to the material tray 10, the material tray 10 is partially located inside the main body 100 and partially located outside the main body 100. Correspondingly, the placement space is partially located in the internal space opened on the main body 100 and partially located outside the main body 100. In the following embodiments, the first direction X refers to the axial direction of the material tray 10 after the material tray 10 is installed in the placement space. The transmission mechanism 200 and the guide member 300 can be connected to the main body 100, or can be set separately, or fixed by an additional support structure.
[0026] The material tray 10 may be in a shape similar to a wire wheel, such as the material tray 10 including a rotating shaft 11 and two end plates 12, and the two end plates 12 are spaced apart on the rotating shaft 10. The wire 20 is wound on the rotating shaft 11 between the two end plates 12. The transmission mechanism 200 may connect and move the wire 20 by extruding the wire 20. The transmission mechanism 200 may move the wire 20 in a forward direction, and the material tray 10 rotates to release the wire 20, or the originally accumulated wire 20 is gradually consumed. The transmission mechanism 200 may move the wire 20 in a reverse direction, and the material tray 10 rotates to rewind the wire 20, and the speed at which the material tray 10 rewinds the wire 20 is not greater than the speed at which the transmission mechanism 200 moves the wire 20.
[0027] The first end of the guide member 300 is opposite to the transmission mechanism 200, and may be spaced apart from the transmission mechanism 200, and corresponds to the insertion position of the wire 20 of the transmission mechanism 200. For example, the transmission mechanism 200 includes two action wheels, and there is a clamping gap between the action wheels, and the clamping gap is used to pass the wire 20, and the first end of the guide member 300 is opposite to the clamping gap. Alternatively, the first end of the guide member 300 may not be opposite to the clamping gap, but there is a certain deviation, such as the first end of the guide member 300 corresponds to one of the action wheels, which is not limited here. It may be that a part of the upper area of the guide member 300 extends toward the placement space, such as the guide member 300 including a part of the second end is inclined upward and extends toward the placement space, and the guide member 300 including a part of the first end extends toward the transmission mechanism 200, and may be approximately extending near the transmission mechanism 200 in the vertical direction. Alternatively, the guide member 300 may extend in a single direction near the placement space. The relative position between the second end of the guide 300 and the tray 10 can be various, such as the second end can extend into the tray 10, or the second end can be arranged close to the edge of the tray 10. At least a part of the area of the guide 300 extends from the first end to the second end to the placement space, so that the wire 20 is guided from the transmission mechanism 200 to the tray 10, so that the wire 20 can move within the range limited by the guide 300. In particular, when the transmission mechanism 200 retracts the wire 20, the guide 300 is used to guide the wire 20 to between the two end plates 12 of the tray 10, and even if the wire 20 is accumulated, it will not fall out of the tray 10. The guide 300 can act on the wire 20 alone to limit the position or movement range of at least a part of the area of the wire 20, or the guide 300 can cooperate with the tray 10 to act on the wire 20 to limit the position or movement range of at least a part of the area of the wire 20. It will be described in conjunction with more specific embodiments below.
[0028] The utility model provides a wire material box and a 3D printer, which mainly limit the position of the wire material by a guide member, so as to avoid the loose consumables between the transmission mechanism and the material tray, causing the consumables to overflow the material tray, and avoid the consumables from overflowing, jamming and knotting. In the prior art, the material tray is usually rewound at a speed equal to or slightly lower than the speed of the wire retraction, which will cause the wire material to accumulate, and the wire material is easy to overflow from the accumulation position to the outside of the material tray, causing the wire material to be unable to be smoothly rewound onto the material tray, causing the wire material to be knotted, and jamming when feeding again. Compared with the prior art, in the present application document, a guide member is provided between the transmission mechanism and the material tray, which can realize the limitation of the position of the wire material, and the wire material retracted by the transmission mechanism will be moved to between the two end plates of the material tray under the guidance of the guide member, and then smoothly rewound onto the material tray, avoiding the problem that the wire accumulated between the material tray and the transmission mechanism overflows outside the end plate and cannot be rewound, and avoiding the consumables that cannot be rewound to be scattered and knotted, affecting the next feeding.
[0029] In one embodiment, a guide hole 301 is opened on the guide member 300 , and the guide hole 301 passes through the first end of the guide member 300 and the second end of the guide member 300 . The guide hole 301 is used to pass the wire material 20 .
[0030] The guide member 300 can be generally a tubular structure, and the second end of the guide member 300 can be located in the middle of the two end plates 12 of the tray 10. Through the positioning of the hole wall of the guide hole 301, the wire 20 moves along the guide hole 301 between the transmission mechanism 200 and the tray 10, so that the moving range of the wire 20 is greatly reduced, and the risk of escaping to the outside of the end plate 12 of the tray 10 can be reduced.
[0031] In one embodiment, the guide hole 301 includes a guide area, the guide area extends to the second end of the guide member 300 , and an opening area of the guide area includes an increasing trend in a direction approaching the second end of the guide member 300 .
[0032] The opening of the guide area becomes larger, which can guide the wire 20 between the guide member 300 and the tray 10 to smoothly enter the guide hole 301. For example, when a new tray 10 is placed, the guide area can facilitate the insertion of the wire 20 and facilitate installation by the user. Or when the wire 20 is accumulated between the guide member 300 and the tray 10, the guide area can prevent the accumulated wire 20 from getting stuck at the edge of the guide hole 301, and can also buffer the wire 20 at the edge of the guide hole 301, so that the wire 20 transitions more smoothly and prevents the wire 20 from being worn by the edge of the guide hole 301.
[0033] In some embodiments, the area of the guide hole 301 at the first end of the guide member 300 is smaller than the area of the guide hole 301 at the second end of the guide member 300, that is, the design is a trumpet-shaped design with one end larger and the other end smaller. Such a design allows the wire 20 to be gradually guided in a trumpet-shaped manner during its movement in the guide hole 301 and smoothly transferred to the material return mechanism 200, thereby avoiding the problem of poor feeding of the wire 20.
[0034] In one embodiment, the guide hole 301 is a circular hole, and the diameter of the guide hole 301 is larger than a preset outer diameter of the wire 20 .
[0035] For example, the preset size may be 0.5 mm, 1 mm, 1.5 mm, etc. For example, if the outer diameter of the wire 20 is 1.75 mm, the diameter of the guide hole 301 may be 2.5 mm, 3 mm, etc. This can limit the position of the wire 20, prevent the wire 20 from swinging greatly, and prevent the guide hole 301 from being too small, resulting in poor transmission of the wire 20.
[0036] In some other embodiments, the guide hole 301 may also be a flat hole. The flat hole provides a freer space for the movement of the wire 20, and the flat hole may be a hole with an elliptical or rectangular cross-sectional profile. The flat hole may be flattened in various directions, and the following takes the opening of the flat hole on the second end of the guide member 300 as an example. Figure 3 and Figure 6 As shown, the length direction of the opening of the guide hole 301 on the second end of the guide member 300 is the first direction X, that is, the length direction of the opening is parallel to the axial direction of the material tray 10, that is, the flattening direction of the guide hole 301 extends in the transverse direction, and then the wire 20 can be wound at any position in the axial direction of the rotating shaft 12 of the material tray 10. Compared with the embodiment in which the guide hole 301 is a circular hole, the winding position of the wire 20 in the axial direction of the rotating shaft 12 will be more uniform, and when the guide hole 301 is a circular hole, the winding position will be concentrated at the axial position of the rotating shaft 12 corresponding to the guide hole 301. Alternatively, in other embodiments, the length direction of the opening of the guide hole 301 on the second end of the guide member 300 is a second direction Y that is perpendicular to the first direction X, that is, the length direction of the opening is perpendicular to the axial direction of the material tray 10, thereby providing a more flexible vertical space for the wire material 20. For example, when there is less wire material 20 on the material tray 10, the wire material 20 will be led out from a position further below the guide hole 301, and when there is more wire material 20 on the material tray 10, the wire material 20 will be led out from a position further above the guide hole 301, thereby reducing the wear of the wire material 20.
[0037] In one embodiment, the cross-sectional area of the guide hole 301 is uniform from the first end of the guide member 300 to the second end of the guide member 300, such as a uniform round hole or a flat hole. Alternatively, in some other embodiments, the cross-sectional area of the guide hole 301 includes an increasing trend from the first end of the guide member 300 to the second end of the guide member 300, and then the opening of the guide hole 301 at one end close to the transmission mechanism 200 is small, which can stabilize the wire 20 before entering the transmission mechanism 200 to prevent the wire 20 from shaking.
[0038] In one embodiment, if Figure 7 As shown, the guide member 300 includes at least one guide plate, which is used to interact with the wire 20 to limit the position of the wire 20 .
[0039] For example, there may be three guide plates, namely, the cover plate 330, the first side plate 340, and the second side plate 350. The first side plate 340 and the second side plate 350 are located on both sides of the cover plate 330 in the first direction X, and form a preset angle with the cover plate 330. The cover plate 330, the first side plate 340, and the second side plate 350 all extend between the two end plates 12. The first side plate 340 and the second side plate 350 are respectively opposite to the two end plates 12, and the interval between the first side plate 340 and the second side plate 350 and the end plates 12 is smaller than the outer diameter of the wire 20. Then, the cover plate 330, the first side plate 340, and the second side plate 350 cooperate with the material tray 10 to prevent the wire 20 from falling out. In some other embodiments, the first side plate 340 and the second side plate 350 may also be located outside the two end plates 12.
[0040] In one embodiment, if Figure 1-3 As shown, at least the second end of the guide 300 has an extension length in the first direction X that is smaller than the distance between the two end plates 12 of the tray 10 , and the second end of the guide 300 is configured to extend between the two end plates 12 .
[0041] By extending the guide member 300 into one side of the end plate 12 or between the two end plates 12, the wire 20 can be introduced into the space of the tray 10 for winding the wire 20, thereby preventing the wire 20 from overflowing. In some embodiments, the difference between the extension length of at least the second end of the guide member 300 in the first direction X and the distance between the two end plates 12 of the tray 10 is less than or equal to the outer diameter of the wire 20, and then when the wire 20 accumulates between the guide member 300 and the tray 10, the wire 20 will not overflow from the gap between the guide member 300 and the end surface of the end plate 20.
[0042] Or, in another embodiment, if Figure 4-6As shown, the second end of the guide member 300 is used to have a preset gap or connection with the edge interval of the end plate 12; and / or, the extension length of at least the second end of the guide member 300 in the first direction X is greater than or equal to the distance between the two end plates 12 of the tray 10, and the second end of the guide member 300 is used to have a preset gap or connection with the edge interval of at least two end plates 12.
[0043] The outer contour of the guide 300 can be an approximately flat arc-shaped plate-like structure. The guide 300 cooperates with a single end plate 12, and covers the edge of the end plate 12 to prevent the wire 20 from slipping out of the end plate 12. The guide 300 cooperates with two end plates 12 at the same time, and covers the openings of the two end plates 12 in part to prevent the wire 20 from slipping out of the end plate 12. The width of the preset gap is less than or equal to the outer diameter of the wire 20, and then when the wire 20 accumulates between the guide 300 and the tray 10, the wire 20 will not overflow from the gap between the guide 300 and the edge of the end plate 20. Alternatively, the guide 300 can also be connected with the end plate 20, such as a sliding connection.
[0044] In one embodiment, at least part of the guide member 300 is elastic. For example, the guide member 300 can be made of an elastic material, such as rubber or silicone. Then, the guide member 300 can be deformed to adapt to the trend of the wire material 20 according to the pulling of the wire material 20, so as to avoid the jamming of the wire material 20 and the guide member 300. At the same time, the guide member 300 can be deformed and can also make way for the disassembly and assembly of the material tray 10, so as to avoid the position of the guide member 300 causing the movement of the material tray 10 to be restricted. It can be understood that the deformation amplitude of the guide member 300 will not be too large, and the deformation of the guide member 300 still has the limiting effect on the wire material 20 of the aforementioned embodiments.
[0045] In some embodiments, the guide member 300 includes a guide body 310 and a flexible member 320, wherein the flexible member 320 is connected to the guide body 310 and extends to the second end of the guide member 300. If the flexible member 320 is a soft rubber strip, the guide body 310 is provided with a guide hole 301, and the flexible member 320 can be arranged around the edge of the opening of the guide hole 301 on the second end of the guide body 310, thereby avoiding the problem of excessive bending and wear of the wire 20 at the edge of the opening, and the flexible member 320 plays a role in buffering and protecting the wire 20.
[0046] In one embodiment, the angle between the extension direction of at least a portion of the second end of the guide 300 and the extension direction of the wire material 20 between the tray 10 and the guide 300 is smaller than a preset angle.
[0047] For example, when the wire 20 at the top end of the material tray 10 begins to separate from the wire 20 wound on the material tray 10 and extends toward the guide member 300, the extension direction of at least a portion of the second end of the guide member 300 can be inclined downward on the second end away from the guide member 300, thereby making the wire 20 enter the guide member 300 more smoothly, thereby avoiding excessive bending of the wire 20 at the edge of the guide member 300 and avoiding excessive friction between the wire 20 and the edge of the guide member 300.
[0048] In one embodiment, the guide member 300 is used to correspond to the material tray 10 one by one, such as the second end of the guide member 300 can extend between the two end plates 12. Alternatively, the guide member 300 is used to correspond to at least two material trays 10, such as the guide member 300 is used to abut against the end plate 12 or spaced by a preset gap, and the guide member 300 can correspond to two or more material trays 10 at the same time.
[0049] In one embodiment, if Figure 8 As shown, the transmission mechanism 200 includes a wire moving assembly, which includes a power wheel 210 and a passive wheel 220, and the passive wheel 220 cooperates with the power wheel 210 to move the wire 20. There is a clamping gap between the power wheel 210 and the passive wheel 220, and the clamping gap is used to pass the wire 20, and the first end of the guide member 300 is opposite to the clamping gap.
[0050] The power wheel 210 and the passive wheel 220 can cooperate to clamp the wire material 20. The power wheel 210 can be used to actively rotate in the forward or reverse direction, thereby feeding and withdrawing the wire material.
[0051] In one embodiment, the transmission mechanism 200 is also used to connect and move the material tray 10. For example, when the wire moving assembly moves the wire 20 for feeding, the material tray 10 can be actively moved to rotate and release the wire 20, and / or, when the wire moving assembly moves the wire 20 for unloading, the material tray 10 can be actively moved to rotate and rewind the wire 20. More specifically, the transmission mechanism 200 includes a wire moving assembly and at least one driving shaft 230, the driving shaft 230 is used to connect with the material tray 10, the wire moving assembly is connected to the driving shaft 230, and the wire moving assembly is used to drive the driving shaft 230 to rotate, so as to drive the material tray 10 to rotate.
[0052] In a more specific embodiment, the main body 100 can be used to connect a single material tray 10, and the position of the passive wheel 220 can include a feeding position and a withdrawing position. In the feeding position, the passive wheel 220 cooperates with the power wheel 210 to clamp the wire 20, and the passive wheel 220 is separated from the driving shaft 230, and the material tray 10 will not actively rotate, and only passively rotates to release the wire 20 under the pull of the moving wire 20. In the withdrawing position, the passive wheel 220 cooperates with the power wheel 210 to clamp the wire 20, and the passive wheel 220 is connected to the driving shaft 230 in transmission. When the wire 20 is withdrawn, the material tray 10 will actively rotate and rewind the returned wire 20.
[0053] The main body 100 can be used to connect multiple material trays 10, and the position of the passive wheel 220 can include a first position and a second position. The first position and the second position can further include a feeding position and a withdrawing position. In the first position, the passive wheel 220 cooperates with the power wheel 210 to clamp the wire material 20 on the material tray 10 corresponding to the first position, and the wire material 20 on the material tray 10 corresponding to the first position can be fed and withdrawn. In the second position, the passive wheel 220 cooperates with the power wheel 210 to clamp the wire material 20 on the material tray 10 corresponding to the second position, and the wire material 20 on the material tray 10 corresponding to the second position can be fed and withdrawn.
[0054] In one embodiment, the driving shaft 230 rotates under the drive of the passive wheel 220, and then drives the material tray 10 to rotate. The driving shaft 230 may be coaxially connected to the material tray 10, such as being connected to the rotating shaft 11 of the material tray 10; or, the driving shaft 230 abuts against the edge of the material tray 10, and if the surface of the driving shaft 230 is a rough surface or a flexible surface, such as a rubber surface, the material tray 10 can be driven to move by friction, so that the driving shaft 230 and the passive wheel 220 can be more centrally arranged and connected more conveniently.
[0055] In one embodiment, the wire material box further includes: a support member 400. In the embodiment where the driving shaft 230 abuts against the edge of the material tray 10, the driving shaft 230 only abuts against one side of the material tray 10, and the support of the material tray 10 also requires the cooperation of the support member 400. The driving shaft 230 and the support member 400 can be arranged at intervals at the bottom end of the material tray 10 to cooperate to achieve the support of the material tray 10. Alternatively, the support member 400 can be coaxially connected to the material tray 10. For example, the support member 400 is rotatably connected to the main body 100, and the support member 400 is used to frictionally abut against the edge of the material tray 10, and then the support member 400 will rotate with the material tray 10; or, the support member 400 is rotatably connected to the main body 100, and the support member 400 is used to be coaxially fixedly connected to the material tray 10, such as being connected to the rotating shaft 11 of the material tray 10; or, the support member 400 is fixedly connected to the main body 100, and the material tray 10 and the support member 400 are slidably abutted, and the support member 400 can be in slidable abutment with the edge of the material tray 10, or, the support member 400 is slidably connected to the rotating shaft 11 of the material tray 10.
[0056] In one embodiment, the main body 100 includes a receiving cavity, the transmission mechanism 200 is at least partially located in the receiving cavity, and the guide 300 is located outside the receiving cavity. The main body 100 is provided with a through hole, which is connected to the receiving cavity and is used to pass the wire 20.
