Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority of Chinese patent application 202420522462.9 filed on March 15, 2024, the entire text of which is incorporated herein by reference. Technical Field

[0003] The utility model relates to the technical field of 3D printing, in particular to a consumable box and a 3D printer. Background Art

[0004] In FDM 3D printers, the filament is wound on a filament tray, and after passing through the extruder, it is introduced into the print head. During the printing process, the extruder continuously squeezes and delivers the filament to the print head, and the filament melts in the print head. Through the relative movement of the print head and the printing platform, the molten filament is sprayed onto the printing platform according to the preset contour.

[0005] In the prior art, consumables are usually placed in a consumable box to protect the consumables and facilitate their use. For example, the patent with publication number CN219968856U discloses a consumable box for a 3D printer, including a box body and a hanger inside the box body, and the hanger is used to support a consumable tray. When changing materials during printing processes such as color printing, the extruder needs to first withdraw the consumables in the print head, which can be coordinated with the active rewinding of the tray or not, but to avoid pulling the consumables. The rewinding speed of the tray will be lower than the speed at which the consumables are withdrawn from the extruder, which will cause the consumables to accumulate between the extruder and the tray, and the consumables wrapped around the tray will loosely expand outward, and the consumables are easy to scatter through the baffle of the tray, affecting the feeding and printing process. Utility Model Content

[0006] In view of this, in order to solve at least one of the aforementioned technical problems, the utility model provides a consumable box and a 3D printer.

[0007] In order to achieve the above purpose, the utility model mainly provides the following technical solutions:

[0008] On the one hand, the utility model provides a consumable box, comprising: a box body, the box body comprising an inner cavity, the inner cavity being used to accommodate a consumable tray; a limiting member, a first part of the limiting member being connected to the box body, and another part of the limiting member extending toward the inner cavity to limit the consumables in the consumable tray.

[0009] The limiting member includes a limiting space and an opening connected to the limiting space, the opening is opposite to the consumable, the opening is used for the consumable to pass through, and the limiting space is used to interact with the consumable through the side wall to limit the position of the consumable.

[0010] On the other hand, the utility model also provides a 3D printer, comprising any consumable box as described above.

[0011] In the present application, since a limiting member is provided in the inner cavity, the movement of the consumables in the consumable tray can be restricted, thereby improving the problem of material entanglement.

[0012] The utility model proposes a consumable box and a 3D printer, which mainly limit the consumables within the limited space through the action of the side wall of the limited space and the consumables, so as to prevent the consumables from loosening and expanding outwards, and prevent the consumables from escaping from the material tray. In the prior art, the consumables are usually placed in the consumable box. When the material needs to be changed, the extruder withdraws the consumables, and the consumables are accumulated between the extruder and the material tray, which will cause the consumables wrapped around the material tray to loosen and expand outwards. The consumables are easy to scatter through the baffle of the material tray, affecting the feeding and printing process. Compared with the prior art, in the present application document, when the consumables are withdrawn, at least the consumables on the outer periphery of the material tray will be loose, and the loose consumables will expand outwards, and then enter the limited space through the opening. Through the action of the side wall of the limited space, the consumables can be confined in the limited space and will not overflow outside the material tray. During the feeding process, the consumables will be tightened with the transmission and then move out of the limited space. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the consumable box proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] On the one hand, if Figure 1-Figure 3 As shown, the embodiment of the utility model provides a consumables box, comprising:

[0018] The box body 100 includes an inner cavity 101, and the inner cavity 101 is at least used to accommodate at least one consumable 20;

[0019] The box body 100 also includes a limiting member, and the limiting member further includes a limiting space 102 and an opening connected to the limiting space 102, the opening is opposite to the consumable 20, the opening is used for the consumable 20 to pass through, and the limiting space 102 is used to interact with the consumable 20 through the side wall to limit the position of the consumable 20.

[0020] The box body 100 can be in various shapes, and can be a square structure with a similar outer contour, or can be an approximate cylindrical structure. The shape and size of the inner cavity 101 and the box body 100 can be set according to the number and size of the trays 10 that need to be placed. In one embodiment, the inner cavity 101 is used to accommodate the tray 10, and the consumables 20 are wound around the tray 10. The inner cavity 101 can be used to place a single tray 10, or multiple trays 10 can be placed. The multiple trays 10 can be arranged in sequence in the axial direction of the tray 10, or in other distribution methods, such as multiple trays 10 are arranged in the radial direction of the tray 10, or multiple trays 10 are distributed at any position in the same plane. In some other embodiments, there may be no tray 10, and the consumables 20 can be only wound around the rotating shaft in the box body 100.

[0021] The material tray 10 usually includes a central axis 12 and an end plate 11 located at at least one end of the central axis 12. The consumables 20 are wound around the central axis 12. There are usually two end plates 11, which are respectively arranged at the two ends of the central axis 12. The end plates 11 are used to limit the consumables 20 between the two end plates 11. The box body 100 usually also has a support member that can realize the rotation of the material tray 10. For example, the support member can be an optical axis, which is connected to the inner hole of the central axis 12. Then, when the consumables 20 are pulled, the material tray 10 can rotate relative to the optical axis to release the consumables 20. Alternatively, a rotating rod that can rotate relative to the box body 100 can be provided, and at least two rotating rods are spaced apart and abut against the bottom edge of the end plate 11, which can then play a role in supporting and realizing the rotation of the material tray 10. Since the tray 10 needs to rotate in the inner cavity 101, in the embodiment where the tray 10 includes an end plate 11, the end plate 11 needs to be spaced apart from the side wall of the inner cavity 101, which makes it easy for the loose consumables 20 to escape from the end plate 11 through the gap. In the embodiment without the tray 10, the loose consumables 20 will move to the area where the adjacent consumables 20 are entangled, which will cause the consumables 20 to be squeezed or knotted. The present application uses the limiting space 102 to limit the consumables 20 to the area corresponding to the limiting space 102, which can prevent the consumables 20 from escaping and avoid the influence between adjacent consumables 20.

[0022] The limiting space 102 can be regarded as a part of the inner cavity 101, and the limiting space 102 can also be regarded as being located in the inner cavity. The opening is an opening that connects the limiting space 102 with the inner cavity 101 or other areas in the inner cavity except the limiting space 102. In the embodiment including the tray 10, the opening is opposite to the consumable 10, which may mean that the opening is opposite to the tray 10, and the opening is at least opposite to the area on the tray 10 where the consumable 20 is wound, such as the entire area or part of the area of ​​the central axis 12. When the consumable 20 is loose, one or more circles of the consumable 20 will expand away from the central axis 12, and then can enter, or most of it will enter into the limiting space 102 through the opening to achieve the limiting effect. When the consumables 20 are not loose, part of the consumables 20 located at the outer ring may also be located in the limiting space 102, which can be adjusted by setting the position of the opening, such as the position of the opening is closer to the central axis 12, and when there are more consumables 20 wound on the central axis 12, part of the consumables will be located in the limiting space 102. Then, when the consumables 20 are loose, the consumables 20 can be directly limited.

[0023] It can be understood that limiting the position of the consumable 20 does not mean completely blocking the movement of the consumable 20. Limiting the position of the consumable 20 means limiting the consumable 20 in a certain space, such as limiting it in a space area composed of the limiting space 102 and the space between the end plate 11. In addition, in an embodiment that does not include the tray 10, a preset distance between the edge of the opening and the consumable shaft can be set. The preset distance can be small, such as less than the diameter of the consumable 20, and then the consumable 20 can be limited entirely by the limiting space 102. The preset distance can be 1 mm, 1.5 mm, etc. In the following embodiments, the embodiment including the tray 10 will be described as an example.

[0024] The consumables box and 3D printer proposed in the embodiment of the utility model mainly realize the consumables being confined within the confined space by the action of the side wall of the confined space and the consumables, so as to prevent the consumables from being loose and expanding outwards and preventing the consumables from escaping from the material tray. In the prior art, the consumables are usually placed in the consumables box. When the material needs to be changed, the extruder withdraws the consumables, and the consumables are accumulated between the extruder and the material tray, which will cause the consumables wrapped around the material tray to be loose and expand outwards. The consumables are easy to scatter through the baffle of the material tray, affecting the feeding and printing process. Compared with the prior art, in the present application document, when the consumables are withdrawn, at least the consumables on the outer periphery of the material tray will be loose, and the loose consumables will expand outwards and then enter the confined space through the opening. Through the action of the side wall of the confined space, the consumables can be confined in the confined space and will not overflow outside the material tray. During the feeding process, the consumables will be tightened with the transmission and then move out of the confined space.

[0025] The limiting space 102 can be formed in various ways, which can be determined according to the structure of the box 100 and the positions of other components disposed in the box 100. For example, in one embodiment, a groove is provided on the box 100 to form the limiting space 102 and the opening. The groove is a groove corresponding to the tray 10, and can be an approximately arc-shaped groove. The tray 10 is embedded in the groove, and the side wall of the groove is located on the outside of the end plate 11 of the tray 10, and the bottom wall corresponds to the edge of the end plate 11.

[0026] Alternatively, in another embodiment, the box body 100 includes a main body 110 and a side baffle 120, the main body 110 includes an inner cavity 101, the side baffle 120 is connected to the main body 110, the side baffle 120 cooperates with the inner wall of the main body 110 to enclose a limited space 102, and the edge of the side baffle 120 is at least a partial area of ​​the opening edge.

[0027] The side baffle 120 is connected to the inner wall of the inner cavity 101 and extends toward the middle area of ​​the inner cavity 101, or in other words, toward the center axis 12 of the tray 10. The angle between the side baffle 120 and the inner wall of the inner cavity 101 may be 90 degrees, or may be other angles. In some embodiments, the side baffle 120 is parallel to the end plate 11 of the tray 10. Compared with the provision of the groove, the side baffle 120 can reduce the processing difficulty of the box 100 and reduce the thickness of the side wall of the box 100.

[0028] A single material tray 10 may correspond to only one side baffle 120, and the side baffle 120, by virtue of the shape of the inner wall of the main body 110, encloses a limited space 102 with the inner wall of the main body 110. For example, if the material tray 10 corresponding to the current limited space 102 is the outermost material tray 10, the axial side of the material tray 10 is close to the side wall of one axial end of the main body 110, and then the side baffle 120 may be one, and is spaced apart from the side wall of one axial end of the main body 110. However, it can be understood that the total number of side baffles 120 included in the box 100 may be one or not. Alternatively, a single material tray 10 corresponds to two side baffles 120, and the two side baffles 120 are spaced apart to cooperate with the inner wall of the main body 110 to enclose the limited space 102. There are two side baffles 120, and the two side baffles 120 are spaced apart and arranged in parallel to limit the consumables 20 on the corresponding material tray 10 between the two side baffles 120. Alternatively, in some embodiments, two adjacent trays 10 share a side baffle 120. That is, the side baffle 120 corresponds to the area between the two adjacent trays 10, and the common side baffle 120 and the side baffle 120 on the first side jointly enclose a first limited space corresponding to the first tray 10, and the common side baffle 120 and the side baffle 120 on the second side jointly enclose a second limited space corresponding to the second tray 10, and the first tray 10 and the second tray 10 are two adjacent trays 10, thereby achieving the effect of reducing the total number of side baffles 120, reducing costs and reducing the space occupied by the side baffles 120.

[0029] In one embodiment, the side baffle 120 is integrally formed with the main body 110, and can be formed by injection molding or extrusion molding, or can be fixedly connected to the main body 110 by ultrasonic welding, bonding, etc. In some other embodiments, the side baffle 120 is detachably connected to the main body 110, and the connection method includes but is not limited to plug-in, clamping connection, sliding connection, magnetic connection or hanging. For example, a clamping member is provided on the side baffle 120, and a groove is provided at a corresponding position on the inner wall of the main body 110, and the width of the groove is slightly smaller than the clamping member, so that the clamping member can be squeezed and embedded in the groove to achieve connection. Alternatively, a slider is provided on the side baffle 120, and a slide groove is provided at a corresponding position on the inner wall of the main body 110. The slider can be embedded in the slide groove from one end of the slide groove, and then the side baffle 120 can be pushed to move into place. Alternatively, one of the magnetic member or the magnetic attraction member can be provided on the side baffle 120, and the other of the magnetic member or the magnetic attraction member can be provided at a corresponding position on the inner wall of the main body 110, and then the magnetic attraction connection can be achieved. Alternatively, it can be suction cup adsorption, wool felt and hook bonding, etc., which will not be listed here one by one. With the detachable connection method, the side baffle 120 can be replaced, such as replacing side baffles 120 of different sizes, or the side baffle 120 can be shifted, such as increasing the distance between two adjacent side baffles 120, and then adapting to different specifications of the tray 10. If the diameter of the end plate 11 of the tray 10 is small, a side baffle 120 with a larger extension is required. If the distance between the two end plates 11 of the tray 10 is large, the distance between the side baffles 120 needs to be increased.

[0030] Since the tray 10 needs to rotate, the tray 10 and the inner wall of the confining space 102 cannot interfere or contact each other. To ensure that the consumables 20 will not fall out of the connection position between the tray 10 and the opening, the tray 10 and the inner wall of the confining space 102 need to have an overlapping area at least in the projection in the axial direction of the tray 10. Take the embodiment in which the tray 10 includes a central axis 12 and an end plate 11 located at at least one end of the central axis 12, and the consumables 20 are wound around the central axis 12 as an example. In order to achieve that the tray 10 and the inner wall of the confining space 102 have an overlapping area at least in the projection in the axial direction of the tray 10, the end plate 310 may include at least a portion of the edge area and the projection of the side wall of the confining space 102 in the axial direction of the tray 10 have an overlapping area.

[0031] More specifically, at least part of the edge of the end plate 310 may be embedded in the limiting space 102, that is, the opposite side walls of the limiting space 102 are located outside the two end plates 310, and then the limiting space 102 cooperates with the material tray 10 to limit the consumables 20 within the area formed by the limiting space 102 and the end plates 310. Or, Figure 3As shown, the limiting space 102 may also be at least partially embedded in the material tray 10, such as the limiting space 102 is enclosed by the side baffle 120, and the side baffle 120 includes at least a partial area of ​​the inner wall edge away from the main body 110 embedded between the two end plates 310 of the material tray 10, so as to confine the consumables 20 within the area formed by the limiting space 102 and the end plate 310.

[0032] The width of the overlapping area between at least part of the edge of the end plate 310 and the projection of the side wall of the limiting space 102 in the axial direction of the material tray 10 can be 3 mm-1 cm, thereby avoiding waste of the limiting space 102 and effectively limiting the consumables 20.

[0033] In one embodiment, there is a gap between the material tray 10 and the side wall of the limiting space 102 at least in the axial direction of the material tray 10, or, in an embodiment where the limiting space 102 is at least enclosed by the side baffle 120, there is a gap between the side baffle 120 and the material tray 10 at least in the axial direction of the material tray 10.

[0034] The gap allows the material tray 10 to rotate freely. In some embodiments, the width of the gap is smaller than the wire diameter of the consumable 20. The wire diameter of the consumable 20 is 1.75 mm, and the width of the gap can be 1 mm, 1.5 mm, etc. This prevents the consumable 20 from leaking out of the gap, and the consumable 20 is not easy to squeeze into the gap to cause jamming.

[0035] In one embodiment, the limiting space 102 is located on a side of the material tray 10 for rolling in or releasing the consumable material 20 .

[0036] The limiting space 102 can be arranged nearly around the material tray 10, leaving only a gap for the consumables 20 to pass through. Alternatively, the limiting space 102 can be located only on one side of the material tray 10 and only extend along a section of the circumference of the material tray 10. In this way, on the one hand, since the texture of the consumables 20 is not very soft, but has a certain hardness, the position of the consumables 20 on one side of the material tray 10 will not have a large range of deviations, which can prevent the consumables 20 from falling out of the material tray 10; on the other hand, the structure of the box 100 can be simplified, the volume of the box 100 can be reduced, the space utilization rate can be increased, and the cost can be reduced. When the consumable 20 is returned, the consumable 20 will accumulate between the position where the consumable 20 is rolled in and released and the consumable conveying member 200. The accumulation of the consumable 20 will cause the position where the consumable 20 is rolled in and released to be easily shifted and displaced. Then, the limiting space 102 is located on one side of the rolled in and released consumable 20, and the position where the consumable 20 is rolled in and released can be limited to ensure the accurate position of the consumable 20 when it is rolled in.

[0037] In one embodiment, the box body 100 includes a main body 110 , and the main body 110 includes a bottom shell 111 and a top cover 112 . The bottom shell 111 and the top cover 112 can move relative to each other to selectively enclose the inner cavity 101 .

[0038] For example, the bottom shell 111 and the top cover 112 are both semi-cylindrical structures with similar cavities, and the bottom shell 111 and the top cover 112 can be connected by hinges to selectively open and close the inner cavity 101, so that the material tray 10 can be taken out and placed. The limiting space 102 can be located on the top cover 112. When the top cover 112 is closed, the limiting space 102 will overlap with the projection of the material tray 10 in the axial direction of the material tray 10, thereby realizing the limiting of the consumables 20. After opening the top cover 112, the material tray 10 will be exposed, and the consumables 20 can be picked up and sorted.

[0039] In one embodiment, the main body 110 further includes a locking portion 113, the locking portion 113 is connected to one of the bottom shell 111 and the top cover 112, and a matching portion is provided on the other of the bottom shell 111 and the top cover 112. The position of the locking portion 113 includes a locking position and an open position, and the locking portion 113 is used to move between the locking position and the open position under the action of an external force. When in the locking position, the locking portion 113 cooperates with the matching portion to fix the relative position of the bottom shell 111 and the top cover 112. When in the open position, the locking portion 113 and the matching portion give way to each other at least in the opening and closing direction of the top cover 112.

[0040] Take the example that the locking part 113 is connected to the bottom shell 111 and the matching part is connected to the top cover 112. The locking part 113 is slidably connected to the bottom shell 111, and the locking part 113 has a hook protruding from the end face of the bottom shell 111 on one side relative to the top cover 112. The main body 110 also includes an elastic member, which is used to provide elastic force to the locking part 113 to move the locking part 113 to the locking position. The matching part is a hanging groove adapted to the hook. When the top cover 112 is closed, the hook of the locking part 113 moves toward the open position under the action of the outer wall of the hanging groove, so as to make way for the outer wall of the hanging groove, and then the hook will extend into the hanging groove, the action of the outer wall of the hanging groove disappears, and the locking part 113 moves back to the locking position under the action of the elastic member, and then hangs with the hanging groove. When it is necessary to open the top cover 112, the locking part 113 is manually moved to the open position, and then the top cover 112 can be opened. The locking portion 113 and the matching portion interact with each other, so that the bottom shell 111 and the top cover 112 are in a stable closed state, are not easy to open, and are not easy to produce gaps, thereby preventing the consumables 20 from being contaminated or damp.

[0041] In one embodiment, the consumable box further includes: a consumable conveying member 200, which is connected to the consumable 20 and is used to convey or pull back the consumable 20. The limiting space 102 extends along the circumferential direction of the material tray 10, and at least part of the opening is used to correspond between the consumable conveying member 200 and the wound consumable 20, so that the consumable 20 led out by the consumable conveying member 200 can pass through.

[0042] The consumables conveying member 200 may be composed of a plurality of gear sets, and the consumables 20 between the gear sets may be driven to move forward and backward by rotating the gear sets in different directions. At least a portion of the opening is used to correspond between the consumables conveying member 200 and the wound consumables 20, and specifically, at least a portion of the opening is used to correspond between the consumables conveying member 200 and the material tray 10, so that the consumables 20 led out of the consumables conveying member 200 can be smoothly led to the material tray 10, avoiding excessive squeezing of the consumables 20 by the edge of the opening, and bending of the surface consumables 20 affecting the smoothness of the transmission.

[0043] In one embodiment, the consumable box further includes: a consumable conveying member 200 and a wire pressing plate 300, wherein the consumable conveying member 200 is connected to the consumable 20 and is used to convey or pull back the consumable 20. The wire pressing plate 300 is connected to the side wall of the box body 100 and / or the limiting space 102, and the wire pressing plate 300 extends toward the consumable conveying member 200, corresponds to the consumable conveying member 200 and the wound consumable 20, and is used to limit the position of the consumable 20 led out by the consumable conveying member 200.

[0044] In the embodiment where the limiting space 102 is at least enclosed by the side baffle 120, the wire pressing plate 300 is connected to the side baffle 120 and the inner wall of the main body 110, and the wire pressing plate 300 is used to guide the consumables 20 led out of the consumable conveying member 200 to enter the vicinity of the material tray 10 to prevent the consumables 20 led out of the consumable conveying member 200 from bending upward in the vertical direction and accumulating. In some embodiments, the end of the side baffle 120 is closer to the consumable conveying member 200 than the wire pressing plate 200, and then the consumables 20 can be limited in the axial direction at a position closer to the consumables 20 led out of the consumable conveying member 200 to prevent the consumables 20 from shaking.
