[0035] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0036] The present application provides a kind of wire reel, such as Figures 1-6As shown, the wire disc is used to accommodate the wire, the wire is wound on the consumable cylinder 6, the shape of the consumable cylinder 6 is hollow column, the wire disc includes: a first wire disc subassembly, the first wire disc subassembly includes a first side plate 1 and a first roller 3, the first roller 3 includes opposite first and second sides, the first side is fixedly connected with the first side plate 1; a second wire disc subassembly, the second wire disc subassembly includes a second side plate 2 and a second roller 4, the second roller 4 includes opposite third and fourth sides; the fourth side is detachably connected with the second side, the third side is fixedly connected with the second side plate 2, the first roller 3 and the second roller 4 are used for the consumable cylinder 6 to be set, and the first wire disc subassembly and / or the second wire disc subassembly are used for at least circumferentially limiting the consumable cylinder 6.

[0037] In actual application, the first side plate 1 and the second side plate 2 can be used to axially limit the printing wire, so that the 3D printing consumable can only be pulled out in a specific direction, avoiding the 3D printing consumable from falling off from both sides to affect the printing progress, the first roller 3 and the second roller 4 are coupled with each other through the coupling part to splice to form a wire disc in the shape of an I-beam, the wire only needs to be wound on the consumable cylinder, and the consumable cylinder is sleeved on the first roller 3 and the second roller 4, so that the wire disc can be reused. In addition, when the axial length of the consumable cylinder 6 is equal to the width between the first side plate 1 and the second side plate 2, the friction generated by the extrusion of the first side plate 1 and the second side plate 2 on the consumable cylinder 6 can be used to circumferentially limit the consumable cylinder 6, the first wire disc subassembly and / or the second wire disc subassembly cannot rotate with each other in the circumferential direction, and the consumable cylinder 6 is synchronously driven to rotate when the wire disc is controlled to rotate, so as to realize accurate control of the consumable, such as high material return accuracy, improved printing effect, and reduced raw material waste during material return. When a multi-color 3D printer switches different color consumables, the consumable in the printing head needs to be cut off, the wire disc is controlled to rotate in the opposite direction to make the consumable in the printing head exit, and the consumable of the target color enters the printing head, so that the wire disc is controlled to rotate to drive the consumable cylinder 6 to rotate, avoiding the consumable cylinder 6 from sliding relative to the wire disc and failing to exit the consumable.

[0038] When the first roller 3 and the second roller 4 are inserted into the consumable cylinder of the wire roll, it is difficult to observe the internal situation of the wire roll with the naked eye, so it is difficult to accurately and quickly align the first roller 3 and the second roller 4 with each other when the first roller 3 and the second roller 4 are coupled.

[0039] In one embodiment, to solve the above problems, the wire disc further includes a coupling part, the coupling part is fixedly connected with the fourth side of the second roller 4 and extends along the axial direction of the second roller 4, and the coupling part is further coupled with the inner circumferential surface of the first roller 3.

[0040] In practical applications, if the first roller 3 and the second roller 4 are to be coupled, the positioning cylinder 51 is only needed to be inserted into the interior of the first roller 3, and the first roller 3 and the second roller 4 can be quickly coupled with each other.

[0041] In order to improve the stability of the coupling of the first roller 3 and the second roller 4, and avoid the disintegration of the wire coil during the 3D printing process, which can cause the wire coil to be scattered and affect the printing progress, in an embodiment, the coupling portion comprises a positioning cylinder 51, the outer diameter of the positioning cylinder 51 is less than or equal to the inner diameter of the first roller 3, at least one first thread 31 is arranged on the inner circumferential surface of the first roller 3, at least one second thread 52 is arranged on the outer circumferential surface of the positioning cylinder 51, and the first thread 31 and the second thread 52 are screwed after the positioning cylinder 51 is inserted into the interior of the first roller 3.

[0042] In practical applications, the first roller 3 and the second roller 4 can be coupled together by using the first thread 31 and the second thread 52, and even if there is some wear between the first roller 3 and the positioning cylinder 51, the first roller 3 and the second roller 4 can still be stably coupled with each other.

[0043] In actual use, the threads are fixed by using friction, and multiple uses can cause the threads to wear. In addition, the threads can also be loosened due to vibration, rotation and other reasons, which can cause the first roller 3 and the second roller 4 to disintegrate and affect printing. In an embodiment, a limiting protrusion 32 is arranged at the edge of the second side of the first roller 3, the limiting protrusion 32 is aligned with the end of the first thread 31, a limiting recess 41 is arranged at the edge of the fourth side of the second roller 4, the limiting recess 41 is aligned with the end of the second thread 52, and the limiting protrusion 32 is clamped in the interior of the limiting recess 41 when the first thread 31 and the second thread 52 are screwed.

[0044] In practical applications, the limiting protrusion 32 is arranged at the edge of the first roller 3, and the limiting recess 41 is arranged at the edge of the second roller 4. When the first roller 3 and the second roller 4 are fixed by using threads, the limiting protrusion 32 is clamped in the interior of the limiting recess 41, which prevents the first roller 3 and the second roller 4 from rotating and loosening, ensures that the first roller 3 and the second roller 4 can be maintained in the tightest position, and avoids the disintegration of the wire coil.

[0045] In an embodiment, the edge of the fourth side of the second roller 4 is also provided with a avoiding groove 42, the depth of the avoiding groove 42 gradually increases along the tightening direction of the second thread 52, so that the distance between the top surface of the second roller 4 and the bottom surface of the second thread 52 is not less than a predetermined distance threshold.

[0046] In actual application, since the limiting convex point 32 is higher than the edge of the first roller 3, the first convex point gradually approaches the edge of the second roller 4 during the tightening process, and in the last stage of the tightening process, the limiting convex point 32 can abut against the edge of the second roller 4 to affect the mutual fixation of the wire disc, therefore, a avoiding slot 42 is arranged on the edge of the other side of the second roller 4, that is, a part of the edge of the second roller 4 is dug out to provide an avoiding space for the limiting convex point 32, so as to ensure that the limiting convex point 32 can be smoothly clamped into the limiting groove 41.

[0047] In one embodiment, two first threads 31 are arranged on the inner circumferential surface of the first roller 3, and the two first threads 31 are aligned at the head and tail in the axial direction and respectively extend by 180° along the inner circumferential surface of the first roller 3; two second threads 52 are arranged on the outer circumferential surface of the positioning cylinder 51, and the two second threads 52 are aligned at the head and tail in the axial direction and respectively extend by 180° along the outer circumferential surface of the positioning cylinder 51.

[0048] In actual application, the two threads respectively extend by 180° and are aligned at the head and tail, and when the first roller 3 and the second roller 4 are spliced, only 180° rotation is needed to rotate to the predetermined position, thereby improving the efficiency of disassembly and assembly.

[0049] In one embodiment, two limiting convex points 32 are arranged on the edge of the second side of the first roller 3; the two limiting convex points 32 are respectively aligned with the end portions of the two first threads 31; two limiting grooves 41 are arranged on the edge of the fourth side of the second roller 4; the two limiting grooves 41 are respectively aligned with the end portions of the two second threads 52; and when the first thread 31 and the second thread 52 are screwed, the two limiting convex points 32 are respectively clamped inside the two limiting grooves 41.

[0050] In actual application, in order to improve the stability of the connection of the first roller 3 and the second roller 4, two limiting convex points 32 are respectively arranged at the opposite positions of the edge of the first roller 3, which can improve the stability of clamping and avoid uneven stress caused by unilateral clamping, thereby affecting the stability of the connection and improving the stability of the detachable wire disc during use. It can be understood that the materials of the first wire disc part and the second wire disc part are selected from deformable materials such as plastic, and the limiting convex point 32 can thus enter and exit the limiting groove 41.

[0051] In actual application, the wire and the consumable cylinder are fixed by friction, and when the color of the wire is changed, the wire is cut and the wire disc is rotated reversely to pull the wire out of the printing head. In order to make the wire disc pull the wire, the end of the consumable cylinder can be provided with a positioning groove, and the outer circumferential surface of the first roller 3 is further provided with a positioning block 34 which can cooperate with the positioning groove, so that the wire disc can drive the consumable cylinder and the wire roll to rotate when the wire disc rotates.

[0052] In one embodiment, the first roller 3 is provided with a first inner cylinder 33; the first inner cylinder 33 is coaxially arranged with the first roller 3, and the inner side wall of the first roller 3 is fixedly connected with the outer side wall of the first inner cylinder 33 by a reinforcing rib; the second roller 4 is provided with a second inner cylinder 43; the second inner cylinder 43 is coaxially arranged with the second roller 4, and the inner side wall of the second roller 4 is fixedly connected with the outer side wall of the second inner cylinder 43 by a reinforcing rib.

[0053] In actual application, in order to improve the strength of the first roller 3 and the second roller 4 and reduce the material of the wire disc as much as possible, the inner cylinder is arranged in the first roller 3 and the second roller 4 respectively, and the outer side wall of the inner cylinder and the inner side wall of the roller are fixed by the reinforcing rib, which provides support and increases strength while avoiding waste of excessive materials and cost increase.

[0054] In actual use, the use of the wire needs to be observed to avoid the influence of the exhaustion of a certain color of wire on the overall printing progress. If the wire is exhausted, the wire disc needs to be disassembled and the wire needs to be replaced in time.

[0055] In one embodiment, a plurality of perspective windows 11 are arranged on the first side plate 1 and the second side plate 2.

[0056] In actual application, the perspective windows 11 on the first side plate 1 and the second side plate 2 are used to observe the use of the wire, and the thickness of the wire roll can be observed from the side through the perspective windows 11. When the thickness of the wire roll is less than a predetermined value, the user needs to replace the wire roll in time to ensure smooth printing.

[0057] The wire disc assembly provided by the embodiment of the application comprises a consumable cylinder 6 and the wire disc described in the above embodiment, the axial length of the consumable cylinder 6 is less than or equal to the distance between the first side plate 1 and the second side plate 2, and the consumable cylinder 6 is sleeved on the first roller 3 and the second roller 4.

[0058] In actual application, the consumable cylinder 6 is sleeved on the first roller 3 and the second roller 4, and the wire disc limits the circumferential position of the consumable cylinder 6 to drive the consumable cylinder 6 to rotate. When the circumferential length of the consumable cylinder 6 is equal to the width between the first side plate 1 and the second side plate 2, the consumable cylinder 6 can be driven to rotate by the friction of the two side plates. When the length of the consumable cylinder 6 is less than the width between the two side plates, the cross-sectional shape of the consumable cylinder 6 can be adjusted so that the consumable cylinder 6 can be driven to rotate by the wire disc. For example, the consumable cylinder 6 is adjusted to be prismatic, and the first roller 3 and the second roller 4 are also adjusted to be prismatic, so that the first roller 3 and the second roller 4 can drive the consumable cylinder 6 to rotate.

[0059] In an embodiment, the consumable cylinder 6 is hollow cylindrical, the inner diameter of the consumable cylinder 6 is greater than or equal to the outer diameter of the first roller 3, and the end of the consumable cylinder 6 is provided with a positioning groove 61. The outer circumferential surface of the first roller 3 is further provided with a positioning block 34 which can cooperate with the positioning groove 61. The positioning block 34 is located on the first side of the first roller 3.

[0060] When the consumable cylinder 6 is controlled to be cylindrical, a positioning block 34 which can cooperate with the positioning groove 61 is further arranged on the outer circumferential surface of the wire disc to circumferentially limit the consumable cylinder 6.

[0061] In an embodiment, as shown in Figures 7-9 The wire disc assembly further comprises a label holder 7. The label holder 7 comprises a first label connecting portion 71, a second label connecting portion 72 and a connecting portion 75. The connecting portion 75 is coupled with the inner circumferential surface of the consumable cylinder 6 and extends along the axis direction of the consumable cylinder 6.

The second label connecting portion 72 extends in a second direction away from the axis of the consumable cylinder 6. The cross-sectional shape of the label holder 7 is approximately ∪-shaped.

[0062] In an embodiment, the first direction is the radial direction of the consumable cylinder 6.

[0063] In an embodiment, the wire disc assembly further comprises an electronic label. The electronic label is mounted on the first label connecting portion 71 and / or the second label connecting portion 72.

[0064] In an embodiment, the label holder 7 and the wire cylinder are formed by an integral molding process to form an integrated structure.

[0065] Specifically, the connecting part 75 of the label holder 7 is coupled with the inner circumferential surface of the consumable cartridge 6, and the label mounting parts on both sides can mount electronic labels, so as to enable the 3D printer to accurately obtain the information of the consumable in actual 3D printing.
