[0002] In FDM 3D printers, the consumables are wound around a tray, and the tray is hung on a bracket for use. During the printing process, the consumables are directly exposed to the air. However, the consumables are easily exposed to the air for a long time, and are prone to absorbing moisture and becoming easy to break, thus causing printing failures. Moreover, using damp consumables to print models not only affects the surface quality of the model, but is also prone to problems such as wiredrawing and bubbles. The strength is also greatly affected, and in severe cases, the printer may malfunction. The consumables are directly hung on the bracket for use. Since the rewinding speed of the tray is usually lower than the unwinding speed of the extruder, the consumables are accumulated between the extruder and the tray, and are easily scattered and tangled, causing printing failures. The utility model proposes a new solution to the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] In the following detailed disclosure, these embodiments are fully described with reference to the drawings. In order to make the technical scheme of the utility model more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The utility model is further described in detail below in combination with the embodiments and drawings.

[0030] In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance; the term "plurality" refers to two or more, unless otherwise clearly defined. The terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "up", "down", "left", "right", "front" and "back" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation, and therefore, cannot be understood as a limitation on the present invention.

[0032] The first aspect of the utility model is as follows Figure 2-Figure 5 As shown, a consumable accommodating mechanism is provided, which is applied to a 3D printer 300. The 3D printer 300 includes a consumable 1. The consumable accommodating mechanism includes a accommodating shell 2. A accommodating cavity is provided in the accommodating shell 2. The accommodating cavity is used to accommodate the consumable 1. A discharge port 23 corresponding to the consumable 1 is opened on the accommodating shell 2. The discharge port 23 is used for the consumable 1 to pass through.

[0033] In traditional technology, such as Figure 1 As shown, during the printing process, the wire 11 is exposed directly to the air. Affected by the external environment, the wire 11 easily absorbs water and moisture, and is more likely to break when pulled during the printing process. At the same time, the use of deteriorated wire 11 will also affect the surface quality of the printed model, resulting in problems such as wire drawing and bubbles on the surface of the model, which will also have a great impact on the strength of the model, and may even cause 3D printer failure and affect the service life of the 3D printer. At the same time, the consumables 1 are directly hung on the bracket 3 for use, and the wire 11 is easy to loosen and expand outward. There is too much accumulation of wire 11 between the extruder and the tray 12, and there is a problem that the wire 11 falls off the tray 12 or even gets tangled, which affects the feeding and printing process.

[0034] The consumables storage mechanism 100 stores the consumables 1 in a relatively sealed manner through the housing 2. The wire 11 is finally delivered to the extruder through the discharge port 23. The inner diameter of the discharge port 23 is slightly larger than the inner diameter of the cross section of a wire 11, which reduces the impact of the external environment on the storage environment of the storage chamber, that is, avoids the consumables 1 from being directly exposed to the air and affected by the external environment, ensures the stability of the quality of the wire 11, and ensures the quality of the printed model. At the same time, the housing 2 restricts the consumables 1 to prevent the wire 11 from being loose outside the tray 12 and affecting the feeding and printing process.

[0035] In one possible implementation, Figure 1 , Figure 3 and Figure 4 As shown, the consumable material 1 includes a wire 11 and a material tray 12 , and the wire 11 is wound on the material tray 12 .

[0036] It can be understood that the wire 11 is wound on the material tray 12. In a specific implementation, the material tray 12 and the wire 11 are both placed in the accommodating shell 2. A relatively sealed accommodating cavity is formed in the accommodating shell 2. The consumable 1 is stored in the relatively closed accommodating cavity, which can greatly reduce the impact of the external environment on the wire 11 and ensure the stability of the wire 11.

[0037] In one possible implementation, Figure 1 and Figure 3 As shown, the material tray 12 includes a central axis and an end plate located at at least one end of the central axis, the wire 11 is wound around the central axis, and the wire 11 wound around the central axis is located within the projection area of ​​the end plate.

[0038] It can be understood that the wire 11 is wound on the central axis, and there are usually two end plates, which are arranged at both ends of the central axis. The wire 11 is confined between the two end plates, and the outer edge of the wire 11 wound on the central axis does not exceed the projection area of ​​the end plates.

[0039] In one embodiment, the accommodating shell 2 includes a shell body 21 and a cover plate 22, the shell body 21 and the cover plate 22 are connected, the shell body 21 and the cover plate 22 are enclosed to form an accommodating cavity, and the accommodating cavity has a closed internal space.

[0040] It can be understood that the shell body 21 and the cover plate 22 are fixedly connected or detachably connected. When the shell body 21 and the cover plate 22 are fixedly connected, they can be formed into a whole by ultrasonic welding, bonding, etc., and the sealing performance is good. When the shell body 21 and the cover plate 22 are detachably connected, such as snap connection, bolt connection, etc., a sealing gasket can be provided between the shell body 21 and the cover plate 22 to improve the sealing performance.

[0041] The accommodating shell 2 may be a cylindrical structure, a square structure, or other shapes. The shape and size of the accommodating shell 2 and the accommodating cavity may be set according to the size and number of the material tray 12 .

[0042] Among them, one consumable material 1 can be placed in one housing 2, or two or more consumable materials 1 can be placed, and multiple material trays 12 can be arranged in sequence along the axial direction, or in other arrangements. In some other embodiments, there may be no material tray 12, and the wire 11 can be only wound on the rotating shaft in the housing 2.

[0043] In one possible implementation, Figure 3 and Figure 4 As shown, the consumables accommodating mechanism further includes a supporting member 13 , which is used to support the consumables 1 so that a gap is left between the consumables 1 and the side wall of the accommodating shell 2 .

[0044] It is understandable that a support member 13 is provided in the accommodating chamber for supporting the consumable 1, that is, for supporting the central axis so that the material tray 12 can rotate, so as to realize the rotation of the material tray 12 for feeding or withdrawing. A gap is left between the consumable 1 and the side wall of the accommodating shell 2, leaving space for the material tray 12 to rotate, so that the material tray 12 can rotate normally.

[0045] In one possible implementation, Figure 5 As shown, the consumables accommodating mechanism also includes a clamping member 24, which is arranged on the accommodating shell 2 and placed outside the accommodating cavity. The clamping member 24 is arranged corresponding to the discharge port 23 and is used to fix the part of the wire 11 placed outside the accommodating cavity.

[0046] The clamping member 24 is provided to limit the wire 11 passing through the discharge port 23 so that a portion of the wire 11 is located outside the accommodating cavity, making it easy to take the end of the wire 11 for use, and the wire 11 is taken out of the clamping member 24 and stretched outward for use.

[0047] The clamping member 24 can be deformed to clamp or release the wire 11 , and the clamping member 24 can be made of elastic materials such as rubber and silicone.

[0048] In one possible implementation, Figure 5 As shown, a groove is provided on the outer surface of the accommodating housing 2, and the clamping member 24 is placed in the groove.

[0049] It can be understood that the clamping member 24 can be completely placed in the groove and does not protrude from the outer surface of the accommodating shell 2, thereby ensuring that the outer surface of the accommodating shell 2 is relatively flat, improving the aesthetic appearance of the consumable accommodating mechanism 100, and facilitating the stability of the placement of the consumable accommodating mechanism 100, and facilitating packaging and transportation.

[0050] In one possible implementation, Figure 4 As shown, the consumables accommodating mechanism also includes a wire pressing mechanism 25 , at least a portion of which can move toward the wire 11 wound on the material tray 12 so that one end of the wire pressing mechanism 25 is always in contact with the wire 11 .

[0051] By providing a movable wire pressing mechanism 25, a force is continuously applied to the outer edge of the wire 11 wound on the material tray 12 to limit the position of the wire 11, so that the wire 11 wound on the material tray 12 can remain in a tightened state and prevent the wire 11 from spreading outward.

[0052] In one possible implementation, Figure 4 As shown, the wire pressing mechanism 25 is placed in the accommodating cavity, and the wire pressing mechanism 25 includes an abutment member 251 and an elastic member. The first end of the elastic member is connected to the abutment member 251, and the second end of the elastic member is relatively fixed to the position of the accommodating shell 2. The elastic member is used to apply force to the abutment member 251 so that the abutment member 251 and the wire 11 are in an abutting state.

[0053] It is understandable that a portion of the wire pressing mechanism 25 extends toward the wire 11 wound on the material tray 12, and the abutment member 251 abuts against the wire 11 through the elastic member. During use, the wire 11 wound on the material tray 12 gradually decreases, and the inner diameter of the outer edge of the wire 11 gradually decreases. Under the action of the elastic member, the abutment member 251 moves toward the wire 11, so that the abutment member 251 always maintains an abutment state with the outermost edge or the outermost layer of the wire 11. The setting of the elastic member meets the needs of different installation positions of the wire pressing mechanism 25, and the abutment member 251 squeezes the wire 11 more stably.

[0054] In one possible implementation, Figure 4 As shown, the wire pressing mechanism 25 further includes a restraining member 252 , which is connected to the accommodating shell 2 , the elastic member is located inside the restraining member 252 , and a portion of the abutting member 251 is disposed inside the restraining member 252 for restraining the moving direction of the abutting member 251 .

[0055] It can be understood that the constraint member 252 limits the deformation direction of the elastic member and the movement direction of the abutment member 251 , so that the abutment member 251 can keep moving in the direction of the wire 11 .

[0056] In one embodiment, the wire pressing mechanism 25 is placed in the accommodating cavity, and the wire pressing mechanism 25 includes an abutment 251 and a restraining member 252. The restraining member 252 is connected to the accommodating shell 2, and the restraining member 252 is connected to the abutment 251. The abutment 251 is used to abut against the end of the wire 11 toward the direction of gravity.

[0057] It can be understood that the wire pressing mechanism 25 can be arranged above the material tray 12, the constraint 252 is connected to the inner wall of the accommodating shell 2, the abutment 251 is connected to the constraint 252, and the constraint 252 and the abutment 251 are movably connected. When the abutment 251 moves along the constraint 252, the abutment 251 always remains connected to the constraint 252. The constraint 252 can be a guide rail or a guide groove. The constraint 252 is used to limit the moving direction of the abutment 251. The abutment 251 always moves in the direction of gravity under the action of its own weight. The end of the abutment 251 always remains in contact with the top of the outer edge of the wire 11 wound on the material tray 12 to prevent the wire 11 from spreading outward.

[0058] The whole or part of the abutment 251 can be made of a heavier material. By adjusting the weight of the abutment 251, the force applied by the abutment 251 to the wire 11 can be adjusted to satisfy the effect of pressing the wire by the abutment 251's own weight.

[0059] In one possible implementation manner, one end of the abutting member 251 for abutting against the wire 11 is provided with an anti-wear structure, and the abutting member 251 abuts against the wire 11 through the anti-wear structure.

[0060] Among them, the anti-wear structure is arranged on the wire pressing mechanism 25, that is, it is arranged on the abutment 251, and the force between the wire pressing mechanism 25 and the wire 11 is transmitted through the anti-wear structure, which can protect the wire 11 and reduce the wear of the wire 11 by the wire pressing mechanism 25; that is, when the abutment 251 squeezes the wire 11, the anti-wear structure is located between the abutment 251 and the wire 11.

[0061] Furthermore, the anti-wear structure includes a roller and / or a protective layer with a smooth outer surface. By providing the roller, the friction between the wire pressing mechanism 25 and the wire 11 can be rolling friction, which is smaller than the friction of sliding friction between the wire pressing mechanism 25 and the wire 11. By providing a protective layer with a smooth outer surface, the friction can also be reduced, which plays a protective role on the wire 11 and has a low cost.

[0062] The second aspect of the utility model is as follows Figure 2-Figure 7 As shown, a consumable box is provided, including any of the consumable accommodating mechanisms described above, the consumable box including a box body 41 and a limiting groove 42 opened on the box body 41, and the limiting groove 42 is used to accommodate at least one consumable accommodating mechanism 100.

[0063] Among them, the box body 41 can be an approximately cylindrical structure, or an approximately square structure, as well as other shaped structures. The shape and size of the box body 41 and the limiting groove 42 can be set according to the size and quantity of the consumable accommodating mechanism 100.

[0064] It can be understood that the limiting groove 42 is used to accommodate the consumable accommodating mechanism 100, that is, to accommodate the accommodating shell 2, and the consumable accommodating mechanism 100 is placed in the limiting groove 42 through the opening connected to the limiting groove 42, and the opening is the opening that connects the limiting groove 2 with other areas.

[0065] The consumables accommodating mechanism 100 can be used alone, or multiple consumables accommodating mechanisms 100 can be placed in the consumables box 200 for combined use. The consumables accommodating mechanism 100 and the consumables box 200 can be placed on the bracket 3 for combined use.

[0066] Among them, the shape and size of the limiting groove 42 are set according to the consumable accommodating mechanism 100, the consumable accommodating mechanism 100 is embedded in the limiting groove 42, and the side walls of the limiting groove 42 are enclosed on the outside of the consumable accommodating mechanism 100. The side walls of the limiting groove 42 are matched with the side walls of the consumable accommodating mechanism 100 with a small gap. The consumable accommodating mechanism 100 can be limited by the limiting groove 42, and it is also convenient to take the consumable accommodating mechanism 100 out of the limiting groove 42 for replacement.

[0067] It is understandable that the colors of the wires 11 in each consumable accommodating mechanism 100 can be the same or different, and a supply of wires 11 of different colors can be provided for a maximum number of consumable accommodating mechanisms 100. Specifically, the color arrangement of the wires 11 can be selected according to the requirements of the printing model to meet the different requirements of the printing model.

[0068] Among them, when multiple wires 11 are of the same color, when a certain wire 11 is exhausted or about to be exhausted, the wire 11 can be quickly replaced to improve printing efficiency. When multiple wires 11 are of different colors, when the color of the wire 11 needs to be changed, the wire 11 of different colors can be quickly replaced, which solves the problem of the single color of the printing wire 11, expands the scope of use of the product, and is conducive to improving the fineness and aesthetics of the printed model and improving printing efficiency.

[0069] In one possible implementation, Figure 7 As shown, a feed port 43 corresponding to the discharge port 23 is provided on the box body 41 , and the feed port 43 is used for the consumables 1 to pass through.

[0070] A feed port 43 corresponding to the discharge port 23 is provided on the box body 41. The wire 11 in the consumable accommodating mechanism 100 is connected to the extruder through the feed port 43 after passing through the discharge port 23. The inner diameters of the feed port 43 and the discharge port 23 are slightly larger than the cross-sectional diameter of a single wire 11. The feed port 43 is located at a position corresponding to the discharge port 23, and the feed port 43 and the discharge port 23 can be located on the same axis.

[0071] In one possible implementation, Figure 7As shown, a partition 44 is provided in the limiting groove 42 , and the partition 44 is used to separate the limiting groove 42 into at least one limiting compartment. The limiting compartment is arranged corresponding to the consumable accommodating mechanism 100 , and the limiting compartment is used to limit the consumable accommodating mechanism 100 .

[0072] The limiting groove 42 is partitioned into a plurality of limiting compartments by providing a partition plate 44 , and a consumable accommodating mechanism 100 is placed in each limiting compartment separately, so that each consumable accommodating mechanism 100 is stored separately, thereby improving the position stability of the consumable accommodating mechanism 100 .

[0073] The third aspect of the utility model is as follows: Figure 2-Figure 7 As shown, a 3D printer is provided, including any one of the above-mentioned consumables accommodating mechanisms 100, or including any one of the above-mentioned consumables boxes 200.
