[0002] 3D printing technology is a kind of rapid prototyping technology, also known as additive manufacturing. The consumables used in the 3D printing process need to be loaded with plastic spools. When the printer is working, the wire on the spool needs to rotate with the help of a bracket, so as to facilitate the printer to smoothly strip the wire on the spool for use. At present, the common fixed wire brackets on the market are usually as Figure 5 shown, which consists of an "I"-shaped support and four bearings rotating on the support. The spool is placed on the four bearings for use. The existing fixed bracket has good stability and the spool rotates smoothly, and is widely used;

[0003] However, there are still some deficiencies in the assembly of the existing bracket: specifically, during the assembly process, the bearings need to be accurately placed in the grooves of the support and ensure that the bearing holes are aligned with the mounting holes on the support. Users often need to position the bearings with one hand and operate the bolts with the other hand at the same time, which increases the labor intensity. When installing the bearings, due to the limited space of the grooves, it is inconvenient to place the bearings. Therefore, there is still a certain degree of inconvenience in the assembly of the bearings. Therefore, a feeding bracket for a printer is proposed for the above situation. Content of the Utility Model

[0007] Both sides of the base have openings, the openings communicate with the groove, and at one end of the bottom of the inner wall of the groove close to the opening, two chutes are provided.

[0008] The support seat is provided with an arc-shaped groove, the bottom of the support seat is provided with two slide bars, and the support seat is provided with two assembly holes.

[0009] The two slide bars are slidably matched with the two chutes. A first through hole is provided on the bottom surface of the inner wall of the groove, and a first bolt is fitted on the first through hole. The penetrating end of the first bolt is fitted with the assembly hole.

[0010] A rotating rod is rotatably fitted in the arc-shaped groove. The rotating rod has a hollow hole. A second bolt is inserted into the second through-hole on one side of the base. The inserted end of the second bolt passes through the hollow hole and is fitted with the second through-hole on the other side of the base.

[0011] Preferably, there are two bases, and a connecting plate is fixedly connected to the two bases.

[0012] Preferably, the cross-sectional projection of the rotating rod is in the shape of a "work" character.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-5 , a feeding bracket for a printer, including a base 1, a second bolt 7 and a support base 2. The base 1 has a groove 101, and both sides of the outer wall of the base 1 are provided with second perforations 105, and the number of the second perforations 105 is four in total.

[0027] Both sides of the base 1 have openings 102, the openings 102 communicate with the groove 101, and the bottom of the inner wall of the groove 101 is provided with slide grooves 103 near one end of the opening 102, and the number of the slide grooves 103 is two.

[0028] The support base 2 is provided with an arc groove 201, the bottom of the support base 2 is provided with two slide bars 4, and the support base 2 is provided with two assembly holes.

[0029] The two slide bars 4 are slidably matched with the two slide grooves 103. The bottom surface of the inner wall of the groove 101 is provided with a first perforation 104, and a first bolt 5 is fitted on the first perforation 104, and the penetrating end of the first bolt 5 is fitted with the assembly hole.

[0030] A rotating rod 6 is rotatably fitted in the arc groove 201. The rotating rod 6 has a hollow hole. A second bolt 7 is inserted into the second perforation 105 on one side of the base 1, and the penetrating end of the second bolt 7 passes through the hollow hole and is fitted with the second perforation 105 on the other side of the base 1.

[0031] In this implementation mode, when assembling the rotating rod 6, first place the rotating rod 6 in the arc groove 201, and support and lift the rotating rod 6 through the arc groove 201. At this time, the hollow hole on the rotating rod 6 and the second perforation 105 are on the same horizontal line. Then, screw the second bolt 7 into the second perforation 105, and make the second bolt 7 pass through the hollow hole and be fitted with the second perforation 105 on the other side of the base 1 to complete the installation of the rotating rod 6. Thus, the steps of hole alignment are greatly simplified, the manual fine-tuning time during the assembly process is reduced, and the assembly efficiency and convenience are significantly improved.

[0032] When assembling the support base 2, first align the slide bar 4 with the chute 103, and slide the support base 2 into the groove 101 from the opening 102. When the slide bar 4 abuts against the end of the chute 103, at this time, the assembly hole of the support base 2 is aligned with the first through hole 104. Then, screw the first bolt 5 into the support base 2 from the bottom of the base 1. After the first bolt 5 passes through the first through hole 104, it cooperates with the assembly hole to position the support base 2.

[0033] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, there are two bases 1, and a connecting plate 8 is fixedly connected to the two bases 1.

[0034] In this embodiment, the connecting plate 8 and the two bases 1 form a "worker"-shaped structure, and the wire reel loaded with wire can be placed on the rotating rods 6 on the two bases 1 for use.

[0035] In this embodiment, as Figure 1 and Figure 4 shown, the cross-sectional projection of the rotating rod 6 is "worker"-shaped.

[0036] In this embodiment, the "worker"-shaped rotating rod 6 can limit the wire reel, preventing the wire reel from moving during rotation and getting stuck in the gap between the base 1 and the rotating rod 6, which affects the normal operation of the wire reel. Moreover, the "worker"-shaped design ensures the stable rotation of the wire reel while making the two ends of the rotating rod 6 contact the arc-shaped groove 20, with a gap in the middle, reducing friction and ensuring the continuity of the rotation of the rotating rod 6.

[0037] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a rubber pad is provided at the bottom of the base 1, and the rubber pad has anti-slip patterns.

[0038] In this embodiment, the rubber pad and the anti-slip patterns make the base 1 more stable when placed on the platform.

[0039] In this embodiment, as Figure 3 and Figure 4 shown, side plates 3 are provided on the support base 2. The side plates 3 are arc-shaped and there are two side plates 3.

[0040] In this embodiment, the side plates 3 limit the rotating rod 6 placed in the arc-shaped groove 201, preventing the rotating rod 6 from swinging back and forth on the second bolt 7, which affects the stability of the wire reel during rotation.

[0041] In this embodiment, as Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, arc-shaped through grooves are formed on both sides of the outer wall of the base 1, and the arc-shaped through grooves are communicated with the grooves 101.

[0042] In this embodiment, the design of the arc-shaped through groove is to meet the assembly requirements of the wire reel.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
