Description

TECHNICAL FIELD

[0001] The present application relates to the field of consumable support, in particular to a consumable support and a 3D printer. BACKGROUND

[0002] The consumable support is used for loading consumables required for 3D printing. The commonly used consumable support is installed on the back of the base of the 3D printer, which occupies a large space and is not conducive to the user to quickly supplement the consumables. CONTENT OF THE UTILITY MODEL

[0003] In view of the above-mentioned technical problems, the purpose of the present application is to provide a consumable support and a 3D printer comprising the consumable support, which specifically comprises the following technical solutions:

[0004] In a first aspect, the present application provides a consumable support, which is used for being installed on the base of a 3D printer. The consumable support comprises a support shaft and a connecting piece. The support shaft comprises a first segment, a second segment and a third segment connected in sequence. The extension direction of the second segment intersects with the extension direction of the first segment. The first segment and the third segment are arranged on the two sides of the second segment. The third segment is used for supporting consumables of a printing model or loading a consumable tray. The base comprises a first side wall and a second side wall. The planes where the first side wall and the second side wall are located intersect with each other. The first segment is used for being fixedly connected to the first side wall through the connecting piece. The second segment is used for abutting against the outer side of the second side wall.

[0005] The third segment of the support shaft of the consumable support of the present application is used for loading consumables. The first segment of the support shaft is fixedly connected to the base through the connecting piece, so that the consumables are loaded on the base of the 3D printer, thereby facilitating the provision of consumables to the printing head during the printing of the model by the 3D printer.

[0006] The first segment of the support shaft of the consumable support of the present application is fixed to the first side wall, and the second segment abuts against the second side wall, so that the consumable support has more contact positions with the base, thereby maintaining the posture of the consumable support and avoiding the failure of the connection between the consumable support and the base due to the excessive weight of the consumables loaded on the third segment, and the stability of the consumable support is improved. The consumable support of the present application makes full use of the corner space of the base, reduces the space occupied by the consumable support on the back of the base, and is more convenient for the user to supplement the consumables.

[0007] In an embodiment, the connecting piece is integrally formed or fixedly connected with the base. The first segment comprises a connecting groove. The connecting groove is connected with the connecting piece in a matched manner. The matched part of the connecting groove and the connecting piece is arranged in an inclined manner with respect to the vertical direction, so that the end of the third segment away from the second segment is arranged in an inclined manner upwards along the vertical direction in an unloaded state.

[0008] In the embodiment, the connecting groove of the first section of the support shaft is connected with the connecting piece, so that the extending direction of the third section forms an angle with the horizontal direction in the empty state. Under the influence of the weight of the consumable in the loaded state, the end of the third section away from the second section moves downward along the vertical direction, so that the angle is reduced or the extending direction of the third section is parallel to the horizontal direction, thereby avoiding the consumable from falling off due to sliding along the extending direction of the third section, and also enabling the consumable support to have a better appearance.

[0009] In an embodiment, the first section includes a hollow area for exposing part of the connecting piece, and the hollow area extends to the slot of the connecting groove, wherein the base includes at least one fastener, one end of the fastener is connected with the first side wall, and the other end penetrates through the connecting piece.

[0010] In the embodiment, the fastener penetrates through the hollow area and is connected with the connecting piece in the connecting groove, so that the connecting piece can be connected with the first side wall without extending out of the connecting groove, thereby reducing the size of the connecting piece. In addition, the fastener can be connected to the opposite middle part of the connecting piece, so that the force arm between the fastener and the consumable support is reduced, thereby improving the reliability of the connection between the fastener and the consumable support.

[0011] In an embodiment, the connecting piece is in a sheet shape, and a gap is left between the connecting piece and the first side wall, and the gap is used to accommodate and fix part of the groove wall of the connecting groove.

[0012] In the embodiment, the gap between the connecting piece and the first side wall is used to fix the groove wall of the connecting groove, so that the connection between the connecting groove and the connecting piece has higher reliability.

[0013] In an embodiment, along the arrangement direction of the connecting piece and the first side wall, the size of the gap is equal to the thickness of the groove wall of the connecting groove.

[0014] In the embodiment, the connecting piece and the first side wall are parallel to each other, and the connecting piece and the first side wall are respectively attached to the two surfaces on the opposite sides of the groove wall of the connecting groove, thereby increasing the contact area between the connecting piece and the support shaft and between the support shaft and the base, and improving the connection strength between the consumable support and the base.

[0015] In an embodiment, along the direction from the slot opening of the connecting groove to the groove bottom, the thickness of the groove wall of the connecting groove gradually increases, and / or along the direction from the slot opening of the connecting groove to the groove bottom, the size of the gap gradually decreases.

[0016] In the embodiment, the size of the gap or the groove wall gradually changes, so that the groove wall extends into the gap and is clamped in the gap, thereby further improving the connection strength between the consumable support and the base.

[0017] In an embodiment, after the consumable support is connected with the connecting piece, the angle between the groove edge of the connecting groove and the vertical direction is in the range of 3°-10°.

[0018] In the embodiment, by setting the angle range of the angle between the groove edge of the connecting groove and the vertical direction, the angle between the third segment and the horizontal direction is limited, so that the consumable support can be slightly inclined upward in advance, and is in a horizontal position after the consumable or the tray is loaded, so that the consumable or the tray can be installed more stably, and the appearance of the consumable support is improved.

[0019] In an embodiment, the consumable support includes a first plane, the first plane is parallel to the axis of the first segment and the axis of the second segment respectively, and the distance between the axes of any two of the first segment, the second segment and the third segment in the direction perpendicular to the first plane is less than or equal to 15 mm.

[0020] In the embodiment, the maximum distance between the segments of the support shaft in the direction perpendicular to the first plane is set, so as to limit the overall size of the consumable support, that is, the consumable support occupies a smaller space, so that more consumable supports can be installed on the machine base at the same time.

[0021] In an embodiment, the consumable support includes a material guide pipe joint, the material guide pipe joint is used to guide the consumable to the material guide pipe and the print head in sequence, and the distance between the material guide pipe joint and the axis of the second segment is less than or equal to 25 mm.

[0022] In the embodiment, the maximum distance between the material guide pipe joint and the second segment in the direction perpendicular to the first plane is set, so as to limit the overall size of the consumable support, that is, the consumable support occupies a smaller space, so that more consumable supports can be installed on the machine base at the same time.

[0023] In an embodiment, after the consumable support is connected with the connecting piece, the first plane forms an angle with the horizontal direction, so that the material guide pipe joint is located above the third segment in the vertical direction; or the first segment and at least one of the first side walls have a matching plane, and the matching plane forms an angle with the first plane, so that the material guide pipe joint is located above the third segment in the vertical direction.

[0024] In the embodiment, by setting the first plane of the consumable support to form an angle with the horizontal direction, or by matching the first segment and the first side wall through the matching plane, the material guide pipe joint is located above the third segment, so as to reduce the height of the overall center of gravity of the consumable support, so that the first segment and the second segment are staggered in the height direction, so that the force arm for supporting the consumable or the tray is longer, and the stability of the consumable support is improved.

[0025] In an embodiment, the angle between the first plane and the horizontal direction is less than or equal to 60°; or the angle between the matching plane and the vertical direction is less than or equal to 60°.

[0026] In the embodiment, by setting the maximum angle between the first plane and the horizontal direction or the angle between the matching plane and the vertical direction, the support shaft is prevented from being excessively inclined to cause the consumable or the consumable disc to occupy more space at the back of the machine base, and the appearance of the consumable support is improved.

[0027] The embodiment of the present application also provides a 3D printer, which comprises a machine base and the consumable support.

[0028] It can be understood that the 3D printer of the present application reduces the space required by the 3D printer and has higher stability because the consumable support is used to reduce the space occupied by the consumable support at the back of the machine base.

[0045] An embodiment of the present application provides a consumable support 100, which is used to be installed on a base 210 of a 3D printer 200, the base 210 includes a first side wall 211 and a second side wall 212, the planes where the first side wall 211 and the second side wall 212 are located intersect.

[0046] Specifically, in one embodiment, as shown in Figure 1 and Figure 2 , the base 210 includes a first side wall 211 and a second side wall 212, the planes of the first side wall 211 and the second side wall 212 are perpendicular to each other, and the first side wall 211 and the second side wall 212 are connected to each other to form an angle, and the consumable support 100 is installed on the first side wall 211 near the angle.

[0047] Please refer to Figures 3-5 , wherein, Figure 3 schematically illustrates a partial enlarged structural schematic view of the 3D printer 200 provided in an embodiment of the present application; Figure 4 schematically illustrates a partial structural schematic view of the 3D printer 200 provided in an embodiment of the present application; Figure 5 schematically illustrates a structural schematic view of the support shaft 10 from one perspective.

[0048] The consumable support 100 provided in the embodiments of the present application includes a support shaft 10 and a connecting piece 20, the support shaft 10 includes a first segment 11, a second segment 12 and a third segment 13 connected in sequence, the extension direction of the second segment 12 intersects the extension direction of the first segment 11, the first segment 11 and the third segment 13 are arranged on the two sides of the second segment 12, and the third segment 13 is used for supporting the consumable of the printing model or loading the consumable tray of the printing consumable.

[0049] Specifically, in one embodiment, as shown in Figure 3 , the third segment 13 of the support shaft 10 is sleeved with a sleeve 220 on the periphery, and the outer side of the sleeve 220 is used for winding the consumable, so that the consumable is loaded on the consumable support 100. Please refer to Figure 4 and Figure 5 , the extension direction of the first segment 11 and the extension direction of the third segment 13 are parallel, and the first segment 11 and the third segment 13 are spaced apart from each other along the extension direction of the second segment 12.

[0050] The first segment 11 of the consumable support 100 provided in the embodiments of the present application is used for fixedly connected to the first side wall 211 through the connecting piece 20, and the second segment 12 is used for abutting against the outer side of the second side wall 212.

[0051] Please refer to Figure 6 schematically illustrates a partial structural schematic view of the support shaft 10 provided in an embodiment of the present application.

[0052] Specifically, in one embodiment, as shown in Figure 6 , the first segment 11 includes a connecting groove 111, the connecting groove 111 is used for accommodating and fixedly connecting the connecting piece 20, and the first segment 11 is fixedly connected with the first side wall 211 of the base 210 through the connecting piece 20. Please refer to Figure 1and Figure 2 The first section 11 is fixed to the first side wall 211, and the second section 12 is at least partially fitted to the outer side of the second side wall 212 on the side of the first section 11, so as to limit the rotation of the support shaft 10 around the connecting piece 20, and thus maintain the posture of the consumable support 100.

[0053] The third section 13 of the support shaft 10 of the consumable support 100 provided in the embodiments of the present application is used to load consumables, and the first section 11 of the support shaft 10 is fixedly connected to the base 210 through the connecting piece 20, so that the consumables are loaded on the base of the 3D printer, so as to provide consumables for the printing head during the printing of the model by the 3D printer.

[0054] The first section 11 of the support shaft 10 of the consumable support 100 provided in the embodiments of the present application is fixed to the first side wall 211, and the second section 12 is in abutment with the second side wall 212, so that the consumable support 100 has more contact positions with the base 210, and the reliability of the connection between the consumable support 100 and the base 210 is improved. The consumable support 100 can also limit the rotation of the support shaft 10 around the connecting piece 20, so as to maintain the posture of the consumable support 100, avoid the connection between the consumable support 100 and the base 210 from being invalid due to the overloading of the consumables loaded in the third section 13, and improve the stability of the consumable support 100.

[0055] In addition, the existing consumable support is generally fixed to only one of the back and the side of the base, and in the state of loading consumables, a larger space of the back or the side needs to be occupied, which leads to the overall size of the 3D printer being too large, and is not conducive to improving the space utilization of the 3D printer.

[0056] The first section 11 of the consumable support 100 provided in the embodiments of the present application can be connected to the first side wall 211 located at the back of the base 210 through the connecting piece 20, and the second section 12 is in abutment with the second side wall 212 located at the side of the base 210, so that the consumable support 100 provided in the embodiments of the present application can make full use of the space at the corner of the base 210, reduce the space of the back and the side of the base 210 occupied by the consumable support 100, improve the space utilization of the consumable support 100, and facilitate the user to replenish consumables.

[0057] The embodiments of the present application also provide a 3D printer 200, which comprises a base 210 and the consumable support 100 described above, and the consumable support 100 is installed on the base 210.

[0058] The 3D printer provided in the embodiments of the present application reduces the space of the back of the base occupied by the consumable support 100, and thus reduces the space required by the 3D printer 200, and has higher stability.

[0059] Please refer to Figure 7Another partial structure diagram of the 3D printer 200 provided in an embodiment of the present application is shown.

[0060] In an embodiment, as shown in Figure 7 The third section 13 comprises a first part 131 and a second part 132, and the size of the first part 131 is greater than that of the second part 132 along a direction perpendicular to the extension direction of the third section 13, so that the third section 13 forms a groove for accommodating the consumable, the consumable can be wound around the periphery of the second part 132, and the first part 131 can prevent the consumable from being pulled out from the end of the third section 13 away from the second section 12, thereby ensuring the reliability of the third section 13 in loading the consumable.

[0061] Please refer to Figure 8 Another partial enlarged structure diagram of the 3D printer 200 provided in an embodiment of the present application is shown.

[0062] In an embodiment, as shown in Figure 8 The sleeve 220 comprises an accommodation groove 221 for accommodating the consumable to form a tray for loading the consumable. The sleeve 220 is sleeved on the periphery of the second part 132, and the first part 131 can prevent the sleeve 220 from being pulled out from the end of the third section 13 away from the second section 12, thereby ensuring the reliability of the third section 13 in loading the consumable.

[0063] In an embodiment, the size of the first part 131 is greater than that of the inner hole of the sleeve 220 along a direction perpendicular to the extension direction of the third section 13, and the first part 131 is detachably connected with the second part 132, so as to facilitate the loading of the sleeve 220 on the third section 13.

[0064] In an embodiment, the connecting piece 20 is integrally formed or fixedly connected with the base 210, the first section 11 comprises a connecting groove 111, the connecting groove 111 is connected with the connecting piece 20, and the connecting groove 111 and the fitting part of the connecting piece 20 are arranged to be inclined with respect to the vertical direction, so that the end of the third section 13 away from the second section 12 is arranged to be inclined upward along the vertical direction in the unloaded state.

[0065] In an embodiment, as shown in Figure 1 The sleeve 220 is sleeved on the periphery of the third section 13, and the sleeve 220 is not loaded with the consumable, so that the end of the third section 13 away from the second section 12 is inclined upward along the vertical direction. Please refer to Figure 2 After the sleeve 220 is loaded with the consumable, the end of the third section 13 away from the second section 12 is moved downward along the vertical direction under the influence of the weight of the consumable, so that the extension direction of the third section 13 is parallel to the horizontal direction, thereby preventing the consumable from being pulled out due to sliding along the extension direction of the third section 13, and also enabling the consumable support 100 to have a better visual effect.

[0066] In another embodiment, the weight of the consumable is light, and the third section 13 is still inclined upward along the vertical direction at the end away from the second section 12, so that the consumable is prevented from sliding along the extension direction of the third section 13 and falling off, and the consumable support 100 has a better appearance.

[0067] It can be understood that the scheme of inclining the third section 13 upward along the vertical direction at the end away from the second section 12 and the scheme of setting the first part 131 and the second part 132 to different sizes in the above embodiments can be combined to further ensure the reliability of the third section 13 in loading the consumable.

[0068] In an embodiment, the first section 11 includes a hollow area 112 for exposing part of the connecting member 20, and the hollow area 112 extends to the slot opening of the connecting groove 111. The base 210 includes at least one fastener 214, one end of which is connected to the first side wall 211, and the other end of which penetrates the connecting member 20.

[0069] Please refer to Figure 9 Fig. 4 is a structural schematic diagram of another perspective view of the support shaft 10 provided in an embodiment of the application.

[0070] In an embodiment, as Figure 9 shown, the hollow area 112 is located on the side of the first section 11 facing the first side wall 211, and the hollow area 112 extends downward along the vertical direction to the slot opening of the connecting groove 111. One end of the fastener 214 is connected to the first side wall 211, and the other end of the fastener 214 is connected to the connecting member 20. During the process of the connecting member 20 extending into the connecting groove 111, part of the fastener 214 is located in the hollow area 112, so that the connecting member 20 and the connecting groove 111 can be connected to each other.

[0071] In addition, the fastener 214 is connected to the connecting member 20 in the connecting groove 111, so that the connecting member 20 can be connected to the first side wall 211 without extending out of the connecting groove 111, thereby reducing the size of the connecting member 20. The fastener 214 can be connected to the relatively middle part of the connecting member 20, so that the force arm between the fastener 214 and the consumable support 100 is reduced, and the reliability of the connection between the fastener 214 and the consumable support 100 is improved.

[0072] In an embodiment, after the consumable support 100 is connected to the connecting member 20, the included angle between the groove edge of the slot opening of the connecting groove 111 facing the groove bottom and the vertical direction is in the range of 3°-10°.

[0073] Please refer to Figure 10 Fig. 5 is a structural schematic diagram of the connecting member 20 provided in an embodiment of the application.

[0074] In an embodiment, as shown in Figure 10 The connecting piece 20 includes a fitting surface 202 and two through holes 201 arranged at an angle with the fitting surface 202. The first side wall 211 is provided with two corresponding connecting holes arranged in the vertical direction. One end of each fastener 214 is connected to a connecting hole, and the other end is connected to a through hole 201, so that the fitting surface 202 forms an angle with the vertical direction after the connecting piece 20 is fixed to the first side wall 211. That is, after the support shaft 10 is connected with the connecting piece 20, the third section 13 is inclined upward in the vertical direction away from the second section 12 in the unloaded state, and is in a horizontal position after loading the consumables or tray, thereby avoiding the sliding of the consumables along the extension direction of the third section 13, and enabling the consumable support 100 to have a better visual effect.

[0075] In an embodiment, the connecting piece 20 is in a sheet shape, and a gap 230 is left between the connecting piece 20 and the first side wall 211 for accommodating and fixing part of the slot wall 113 of the connecting groove 111.

[0076] In an embodiment, the size of the gap 230 along the arrangement direction of the connecting piece 20 and the first side wall 211 is equal to the thickness of the slot wall 113 of the connecting groove 111. The connecting piece 20 and the first side wall 211 are parallel to each other, and the connecting piece 20 and the first side wall 211 are respectively fitted to the two opposite surfaces of the slot wall 113 of the connecting groove 111, thereby increasing the contact area between the connecting piece 20 and the support shaft 10 and between the support shaft 10 and the machine base 210, and improving the connection strength between the consumable support 100 and the machine base 210.

[0077] In an embodiment, the thickness of the slot wall 113 of the connecting groove 111 gradually increases along the direction from the slot opening to the slot bottom.

[0078] Please refer to Figure 11 the partial cross-sectional view of the 3D printer 200 provided in an embodiment of the present application.

[0079] In an embodiment, as shown in Figure 11 The fastener 214 is connected between the connecting piece 20 and the first side wall 211 and forms the gap 230. The thickness of the slot wall 113 gradually increases along the direction from the slot opening to the slot bottom of the connecting groove 111, and the distance between the slot wall 113 and the connecting piece 20 and between the slot wall 113 and the first side wall 211 gradually decreases along the horizontal direction as the slot wall 113 extends into the gap 230, until the slot wall 113 is clamped in the gap 230, thereby further improving the connection strength between the consumable support 100 and the machine base 210.

[0080] In an embodiment, the size of the gap 230 gradually decreases along the direction of the slot of the connecting slot 111 towards the slot bottom, which can also enable the slot wall 113 to be clamped in the gap 230, and further improve the connection strength between the consumable support 100 and the machine base 210.

[0081] In an embodiment, the consumable support 100 includes a first plane parallel to the axis of the first section 11 and the axis of the second section 12, respectively, and the distance between the axes of any two of the first section 11, the second section 12 and the third section 13 in a direction perpendicular to the first plane is less than or equal to 15 mm. The maximum distance between the sections of the support shaft 10 in a direction perpendicular to the first plane is set to limit the overall size of the consumable support 100, i.e., the consumable support 100 occupies less space, facilitating the reduction of the packaging volume and allowing more consumable supports 100 to be installed on the machine base 210 at the same time.

[0082] It can be understood that in the process of printing a model, a 3D printer often needs to use consumables of multiple colors or multiple materials to meet the needs of the model, and the machine base 210 allows more consumable supports 100 to be used, facilitating the use of the 3D printer by the user.

[0083] In an embodiment, as shown in Figure 7 , the consumable support 100 includes a material guide pipe joint 30 for guiding the consumables to the material guide pipe and the print head in sequence, and the distance between the material guide pipe joint 30 and the axis of the second section 12 is less than or equal to 25 mm. The maximum distance between the material guide pipe joint 30 and the second section 12 in a direction perpendicular to the first plane is set to limit the overall size of the consumable support 100, i.e., the consumable support 100 occupies less space, allowing more consumable supports 100 to be installed on the machine base 210 at the same time.

[0084] In an embodiment, after the consumable support 100 is connected with the connecting piece 20, an included angle is formed between the first plane and the horizontal direction.

[0085] In an embodiment, as shown in Figure 3 , in the vertical direction, the third section 13 is at least partially below the first section 11, and the material guide pipe joint 30 is at least partially above the third section 13, which can make the first section 11 and the second section 12 staggered in the height direction, making the force arm of the support consumable or tray longer, and improving the stability of the consumable support 100.

[0086] In an embodiment, the first section 11 has a matching plane 114 with at least one of the first side wall 211, and the matching plane 114 forms an angle with the first plane, so that the material guide pipe joint 30 is located above the third section 13 in the vertical direction.
