Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printing, and in particular relates to a consumable material reel for 3D printing. Background Art

[0002] 3D printing consumables are made by winding the wire around a reel. In order to make it easier to fix the wire during winding, a threading hole is opened on the reel, and the wire head is inserted into the hole. The wire is bent at the turning point between the threading hole and the inside of the reel, and the wire head is stuck in the hole and pre-fixed. As the reel rotates, the wire will bend again at the turning point between the threading hole and the outside of the reel, adding a fixing point. As the reel rotates, the wire is wound around the reel. However, during 3D printing, when the wire is consumed, the wire head is still stuck on the reel, which can easily cause the 3D printer to jam during printing. If not handled in time, the 3D printer will not work properly, causing the product to be scrapped.

[0003] Current consumables reels usually have the head of the wire cut off during printing to prevent clogging. However, in actual applications, only the inner part of the winding barrel can be cut off, and the part inside the hole is still stuck inside, which may eventually cause clogging. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a consumable material reel for 3D printing, which solves the problem of easy clogging during use.

[0005] The utility model comprises: a wire drum body, wherein the wire drum body is provided with wire threading holes and wire breaking openings, and the wire threading holes and the wire breaking openings are distributed along the circumference of the wire drum body.

[0006] Optionally, the threading hole is close to the end of the wire drum body, and the wire breaking opening is located at the end of the wire drum body.

[0007] Optionally, both ends of the wire drum body are provided with wire threading holes and wire breaking openings.

[0008] Optionally, the wire drum body includes a winding drum and side plates arranged at both ends of the winding drum, and the wire breaking opening extends radially of the wire drum body and axially penetrates the side plates.

[0009] Optionally, the length of the wire breaking opening extending radially toward the wire drum body is 2-50 mm.

[0010] Optionally, the length of the wire breaking opening along the axial direction of the wire drum body is 2-20 mm.

[0011] Optionally, the height of the winding drum is 5-60 cm and the outer diameter is 3-30 cm; the shape of the side plate is ring-shaped and the outer diameter is 5-80 cm.

[0012] Optionally, the distance between the threading hole and the wire breaking opening is 1-20 mm.

[0013] Optionally, the threading hole is a round hole with a hole diameter of 1-10 mm.

[0014] Optionally, the edge contour of the wire breaking opening is a polygonal structure.

[0015] The beneficial effect of the utility model is that the wire end portion of the wire body passes through the pipeline hole and is bent and stuck. During the winding process of the wire body, the first circle passes through the outside of the wire breaking mouth. The first circle of the wire body can be observed through the inside of the wire drum body, that is, the inside of the wire breaking mouth. When in use, the first circle of the wire body is cut or separated with scissors or a knife. When the wire is consumed, the wire end will not be stuck on the wire body, which will easily cause the 3D printer to get stuck during printing. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-3 As shown, the utility model provides a 3D printing consumables reel, including a reel body, wherein the reel body is provided with threading holes 13 and a wire breaking opening 14, and the threading holes 13 and the wire breaking opening 14 are distributed along the circumference of the reel body.

[0021] Compared with the prior art, the utility model provides a 3D printing consumables reel, in which the thread end 21 of the wire body 20 partially passes through the pipeline hole and is bent and stuck. During the winding process of the wire body 20, the first circle passes through the outside of the wire breaking opening 14, and the first circle of the wire body 20 can be observed through the inside of the reel body, that is, the inside of the wire breaking opening 14. When in use, the first circle of the wire body 20 is cut or separated with scissors or a knife. When the wire is consumed, the thread end 21 will not be stuck on the wire body 20, which will easily cause the 3D printer to get stuck during printing.

[0022] It should be noted that, in some cases, a small hook can be used to hook up the wire body 20 from the inside of the wire cutting mouth 14; the 3D printer has a special extruder to push and guide the wire body 20. When the first circle of wire is cut off, there will be no impact if the wire is scattered when only a few circles are left on the wire reel.

[0023] In this embodiment, the threading hole 13 is close to the end of the wire drum body, and the wire breaking opening 14 is located at the end of the wire drum body. Specifically, the threading hole 13 is close to the end of the wire drum body for winding, and the wire breaking opening 14 extends in the radial direction and the axial direction of the wire drum body. First, the end of the winding drum 11 can be used as the starting end of the wire. In addition, the first circle of wire can be fully exposed to facilitate the wire breaking operation.

[0024] Furthermore, both ends of the wire drum body are provided with threading holes 13 and wire breaking openings 14, so that both ends of the wire drum body can become fixed ends of the wire ends 21. Specifically, the threading holes 13 and wire breaking openings 14 at both ends of the wire drum body can be on the same side or staggered.

[0025] In one embodiment, the wire reel body includes a winding drum 11 and side plates 12 arranged at both ends of the winding drum 11. The wire breaking opening 14 extends radially toward the wire reel body and axially penetrates the side plates 12. With such a configuration, the remaining amount of wire can be observed through the wire breaking opening 14, and preparations can be made in advance for wire replacement, reducing the waiting time required for the 3D printer to prompt a prompt after the wire is used up.

[0026] In this embodiment, the radial extension length of the wire break opening 14 to the wire drum body is 2-50 mm, that is, the length of the wire break opening 14 on the side plate 12. Preferably, the radial extension length of the wire break opening 14 to the wire drum body is 5-10 mm, which needs to be larger than the diameter of the wire used, and the strength of the side plate 12 must be sufficient.

[0027] In this embodiment, the length of the wire break opening 14 along the axial direction of the wire drum body is 2-20 mm, that is, the length of the wire break opening 14 on the winding drum 11. Preferably, the length of the wire break opening 14 along the axial direction of the wire drum body is 5-10 mm, which needs to be larger than the diameter of the wire used, and the strength of the winding drum 11 must be sufficient.

[0028] In this embodiment, the height of the winding drum 11 is 5-60 cm and the outer diameter is 3-30 cm; the side plate 12 is ring-shaped and has an outer diameter of 5-80 cm.

[0029] In one embodiment, the distance between the threading hole 13 and the wire breaking opening 14 is 1-20 mm. The closer the distance between the threading hole 13 and the wire breaking opening 14 is, the shorter the thread end 21 discarded due to cutting is. It is also necessary to ensure that there is sufficient mechanical strength between the threading hole 13 and the wire breaking opening 14. Preferably, the distance between the threading hole 13 and the wire breaking opening 14 is 3-5 mm.

[0030] In one embodiment, the threading hole 13 is a circular hole with a hole diameter of 1-10 mm. Of course, it can also be a polygonal hole or an elliptical hole. The extension direction of the threading hole 13 is perpendicular to and coincides with the circumference of the winding drum 11.

[0031] In one embodiment, the wire breaking opening 14 is a polygonal structure. Specifically, the wire breaking opening 14 is divided into two parts on the winding drum 11 and the side plate 12. It can be regarded as a wire breaking opening 14 formed by turning a right-angle plate at the inner end of the wire drum body; in some embodiments, the edge of the wire breaking opening 14 can also be composed of a smooth transition of an arc.
