[0002] With the popularization of 3D printing technology, the use of 3D printing consumables has also increased dramatically. In the existing technology, most of the 3D printing consumables winding reels are integrated structures. Each roll of consumables needs to be equipped with a set of winding reels, which cannot be reused. Therefore, for companies that use a large number of consumables, after the consumables are used up, the winding reels will pile up like mountains, taking up a large storage space. When the wire is used up, the reel is directly discarded and cannot be recycled, resulting in a high waste of resources and environmental pollution. Utility Model Content

[0003] The purpose of the utility model is to provide a recyclable 3D consumables reel to solve the technical problems of high resource waste and environmental pollution caused by the inability to reuse existing integrated winding reels.

[0005] Furthermore, the plug-in structure includes a plurality of first engaging ends arranged on the first connecting shaft portion and a plurality of second engaging ends arranged on the second connecting shaft portion, the first engaging ends are provided with a first engaging groove and a first engaging block, the second engaging ends are provided with a second engaging groove and a second engaging block, and when the first engaging end and the second engaging end are buckled with each other, the first engaging block is engaged in the second engaging groove, and the second engaging block is engaged in the first engaging groove.

[0006] Furthermore, the first connecting shaft portion and the second connecting shaft portion both include an inner ring and an outer ring, an inner groove is formed between the inner ring and the outer ring, and the first clamping end and the second clamping end are arranged around the upper surface of the inner ring.

[0007] Furthermore, the first connecting shaft portion and the second connecting shaft portion are respectively provided with a first limit block and a second limit block. When the first connecting shaft portion and the second connecting shaft portion are engaged with each other, the first limit block extends into the inner groove on the second connecting shaft portion and fits against the inner wall of the outer ring, and the second limit block extends into the inner groove on the first connecting shaft portion and fits against the inner wall of the outer ring.

[0008] Furthermore, the first connecting shaft portion and the first wire retaining drum are integrally formed, and the second connecting shaft portion and the second wire retaining drum are integrally formed.

[0009] Furthermore, the first wire retaining drum and the second wire retaining drum are both provided with a plurality of hollowed-out portions.

[0010] Furthermore, the diameter of the connection surface between the first connecting shaft and the first wire retaining drum is larger than the diameter of the first connecting shaft away from the first wire retaining drum, and the diameter of the connection surface between the second connecting shaft and the second wire retaining drum is larger than the diameter of the second connecting shaft away from the second wire retaining drum.

[0028] like Figure 1-4 The first embodiment of the utility model is shown: a recyclable 3D consumables wire reel, comprising a first wire reel 1 and a second wire reel 2, the first wire reel 1 having a first connecting shaft 101, the second wire reel 2 having a second connecting shaft 201 matching the first connecting shaft 101, the first connecting shaft 101 and the second connecting shaft 201 being interlocked with each other through a plug-in structure to form a winding portion 3. The winding portion 3 is provided with a wire end clamping hole, and the first wire reel 1 and the second wire reel 2 are connected as a whole through the plug-in structure, which can not only be used for winding and operation of 3D printing consumables, but also the first wire reel 1 and the second wire reel 2 can be separated after each printing material is used up, and the new material can be directly sleeved on the connecting shaft of the wire reel on one side, and then the wire reel on the other side is buckled thereon to complete the loading of the new printing material, thereby realizing the reuse of the wire reel.

[0029] The first wire reel 1 and the second wire reel 2 have the same structure and shape. When one of the first wire reel 1 or the second wire reel 2 is damaged during use, consumers only need to replace the other wire reel to continue using it without replacing the entire wire reel, thus avoiding waste of resources.

[0030] This structure is applicable to printed materials packaged with a paper-plastic sleeve, which can be directly sleeved on the winding part 3 through the paper-plastic sleeve.

[0031] like Figure 2-3 As shown: the plug-in structure includes a plurality of first engaging ends 102 arranged on the first connecting shaft portion 101 and a plurality of second engaging ends 202 arranged on the second connecting shaft portion 201, the first engaging end 102 is provided with a first engaging groove 103 and a first engaging block 104, the second engaging end 202 is provided with a second engaging groove 203 and a second engaging block 204, when the first engaging end 102 and the second engaging end 202 are buckled with each other, the first engaging block 104 is engaged in the second engaging groove 203, and the second engaging block 204 is disposed in the first engaging groove 103.

[0032] By arranging the first engaging end 102 and the second engaging end 202 on the first connecting shaft portion 101 and the second connecting shaft portion 201, and opening mutually matching engaging grooves and engaging blocks thereon, when the first wire retaining drum 1 and the second wire retaining drum 2 need to be assembled, the first connecting shaft portion 101 and the second connecting shaft portion 201 are firstly buckled correspondingly, so that the first engaging end 102 and the second engaging end 202 are staggered with each other, and then the first connecting shaft portion 101 or the second connecting shaft portion 102 is rotated so that the engaging block on one side of the connecting shaft portion is gradually inserted into the engaging groove of the other side of the connecting shaft portion, and when the engaging block is completely embedded in the engaging groove, the connection between the first wire retaining drum 1 and the second wire retaining drum 2 is completed, and this plug-in method has strong stability and high connection strength, and is also convenient for disassembly and assembly.

[0033] like Figure 4 As shown, the first connecting shaft portion 101 and the second connecting shaft portion 201 both include an inner ring 4 and an outer ring 5 , an inner groove 6 is formed between the inner ring 4 and the outer ring 5 , and the first clamping end 102 and the second clamping end 202 are arranged around the upper surface of the inner ring 4 .

[0034] like Figure 2-3 As shown: the first connecting shaft portion 101 and the second connecting shaft portion 201 are respectively provided with a first limit block 105 and a second limit block 205. When the first connecting shaft portion 101 and the second connecting shaft portion 201 are interlocked with each other, the first limit block 105 extends into the inner groove 6 on the second connecting shaft portion 201 and fits against the inner wall of the outer ring 5, and the second limit block 205 extends into the inner groove 6 on the first connecting shaft portion 101 and fits against the inner wall of the outer ring 5. The function of the first limit block 105 and the second limit block 205 is that when the load on them is too large, the first limit block 105 and the second limit block 205 are inserted into the inner groove 6 of the connecting shaft portion opposite thereto in an interlaced manner, so as to effectively increase the strength of the connection between the two, thereby avoiding the situation that the first stopper drum 1 and the second stopper drum 2 are misaligned due to unstable connection under high-intensity work.

[0035] like Figure 1-3 As shown in the figure, the first connecting shaft 101 and the first wire retaining drum 1 are integrally formed, and the second connecting shaft 201 and the second wire retaining drum 2 are integrally formed, and the integral forming method can greatly enhance the stability of the wire drum. The first limit block 105 and the second limit block 205 are respectively integrally fixed on the inner wall of the outer ring 5 of the first connecting shaft 101 and the second connecting shaft 201.

[0036] like Figure 1 As shown, a plurality of hollow parts 7 are provided on the first wire drum 1 and the second wire drum 2. The design of the hollow parts 7 can reduce weight and material.

[0037] The diameter of the connection surface between the first connection shaft portion 101 and the first wire retaining drum 1 is larger than the diameter of the first connection shaft portion 101 away from the first wire retaining drum 1, and the diameter of the connection surface between the second connection shaft portion 201 and the second wire retaining drum 2 is larger than the diameter of the second connection shaft portion 201 away from the second wire retaining drum 2. This arrangement can make it easier to install the printing material with the paper-plastic sleeve, so that the paper-plastic sleeve can be clamped therein to prevent displacement.

[0038] like Figure 1-3 As shown, the first wire retaining drum 1 and the second wire retaining drum 2 are coaxially arranged opposite to each other, and a central hole 8 is provided on both the first wire retaining drum 1 and the second wire retaining drum 2 , and the central hole 8 passes through the first connecting shaft portion 101 and the second connecting shaft portion 201 .

[0039] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
