Description

Technical Field

[0001] This utility model relates to the field of printing materials technology, specifically a self-adhesive, splicable 3D printing filament reel. Background Technology

[0002] 3D printing filament reels are devices used to wind 3D printing filaments. They are generally used to wind filaments pulled out by the 3D printer's feed mechanism. There are many types of 3D printing filament reels on the market, and the appropriate type should be selected according to different application scenarios.

[0003] In the prior art, Chinese Patent No. CN223444901U discloses an automatic 3D printing filament winding device, including a frame, a hopper for holding a fixing rod, a filament reel for winding 3D printing filament, and a power structure. The filament reel is rotatably connected to the frame, and includes a rotating shaft and turntables at both ends of the shaft. The hopper is located at the edge of the filament reel, and the power structure pushes the fixing rod in the hopper between the two turntables, causing the fixing rod to engage between them. Its advantage is that after a certain amount of 3D printing filament is wound around the rotating shaft, the power structure pushes the fixing rod in the hopper between the two turntables, causing it to engage. At this point, the fixing rod clamps the 3D printing filament, and then the 3D printing filament is cut. The fixing rod prevents the 3D printing filament from unraveling, thus securing it. This device can quickly fix the 3D printing filament without manual intervention, improving the efficiency of the fixing process.

[0004] Most of the existing technologies mentioned above improve the overall structure. However, the existing 3D printing filament reels are inconvenient to splice together as a whole during operation, making it inconvenient to store the reels when not in use, taking up a lot of space, and also making them difficult to replace, thus reducing the effectiveness of the filament reels. Utility Model Content

[0005] The purpose of this invention is to provide a self-adhesive, splicable 3D printing filament reel to solve the problem mentioned in the background art that existing 3D printing filament reels are inconvenient to splice together during operation, making it difficult to store when not in use, taking up a lot of space, and not easy to replace, thus reducing the effectiveness of the filament reel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a self-adhesive and splicable 3D printing filament reel, comprising a first connecting reel, a first sleeve fixed on the inner wall of the first connecting reel, and a sleeve rod connected to the inner side of the first sleeve; It also includes: a second connecting plate is provided on the rear side of the first connecting plate, and a second sleeve is fixed on the inner wall of the second connecting plate; The inner side of the second sleeve is connected to a fixing rod. The outer walls of the first and second connecting plates are both equipped with mounting rods, and the bottom of the mounting rod is fixed with a support rod. The mounting rod on the left side is equipped with a rocker arm, and the end of the rocker arm passes through the mounting rod, the first connecting plate and the first sleeve and is fixed to the sleeve rod. The second connecting disc is provided with a limiting structure to limit the winding of the wire and prevent it from becoming messy.

[0007] Preferably, the outer wall of the fixing rod is fixed with connecting blocks distributed at equal angles, and the connecting blocks are connected to the sleeve rod through connecting grooves, and the connecting grooves are opened at equal angles on the inner wall of the sleeve rod.

[0008] Preferably, a first magnet is installed inside the sleeve rod, and a second magnet is installed at the end of the fixing rod away from the second sleeve, with the second magnet and the first magnet having opposite magnetic poles facing each other.

[0009] Preferably, the limiting structure includes a limiting rod that passes through the second connecting plate, and the rear end of the limiting rod is connected to the limiting plate, and a connecting spring is installed between the limiting plate and the second connecting plate.

[0010] Preferably, the connecting spring is located outside the limiting rod, and the limiting rod and the limiting plate are an integral structure, and the limiting plate and the mounting rod on the right side do not contact each other.

[0011] Preferably, a clamping block is provided between the limiting plate and the second connecting plate, and the clamping block is U-shaped. The limiting rods are distributed at equal angles, and the limiting rods and the second connecting plate are slidably connected.

[0012] Preferably, the sleeve rod and the first sleeve are rotatably connected, and the fixed rod and the second sleeve are rotatably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This self-adhesive, splicable 3D printed wire reel has connecting blocks that are evenly distributed on the outer wall of the fixing rod. The connecting blocks are connected to the sleeve rod through connecting grooves. This allows the fixing rod and the sleeve rod to be firmly connected through the interlocking between the connecting blocks and the connecting grooves, thereby completing the splicing between the first and second connecting reels and improving the use effect of the wire reel. Furthermore, a first magnet is installed inside the sleeve rod, and a second magnet is installed at the end of the fixing rod away from the second sleeve. The second magnet and the first magnet are set with opposite magnetic poles facing each other. The attraction between the first magnet and the second magnet can make the connection between the fixing rod and the sleeve rod more stable, thereby making the wire reel more stable when in use. Furthermore, a limiting structure is provided, which includes a limiting rod, a limiting plate, a connecting spring, and a clamping block. This facilitates the limiting of a roll of material of a certain thickness, preventing the roll from becoming loose and messy. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6This utility model provides the following technical solution: a self-adhesive, splicable 3D printing filament reel, including a first connecting reel 1, a first sleeve 5 fixed on the inner wall of the first connecting reel 1, and a sleeve rod 2 connected to the inner side of the first sleeve 5; further including: a second connecting reel 6 disposed on the rear side of the first connecting reel 1, and a second sleeve 10 fixed on the inner wall of the second connecting reel 6; a fixing rod 7 connected to the inner side of the second sleeve 10, and connecting blocks 8 evenly distributed at angles fixed on the outer wall of the fixing rod 7, and the connecting blocks 8 being connected to the sleeve rod 2 through connecting grooves 3, and the connecting grooves 3 being evenly opened at angles on the inner wall of the sleeve rod 2. The sleeve rod 2 is equipped with a first magnet 4. The fixed rod 7 is equipped with a second magnet 9 at the end away from the second sleeve 10. The second magnet 9 and the first magnet 4 are arranged with opposite magnetic poles facing each other. The outer walls of the first connecting plate 1 and the second connecting plate 6 are both equipped with mounting rods 11. The bottom of the mounting rod 11 is fixed with a support rod 12. The mounting rod 11 on the left side is equipped with a rocker arm 13. The end of the rocker arm 13 passes through the mounting rod 11, the first connecting plate 1 and the first sleeve 5 and is fixed to the sleeve rod 2. The sleeve rod 2 and the first sleeve 5 are rotatably connected. The fixed rod 7 and the second sleeve 10 are rotatably connected.

[0018] When using this wire reel, first position the left support rod 12 to support the first connecting reel 1. Since a first sleeve 5 is installed on the inner wall of the first connecting reel 1, and a sleeve rod 2 is rotatably connected inside the first sleeve 5, a connecting groove 3 is provided on the inner wall of the sleeve rod 2. The connecting groove 3 and the connecting block 8 on the outer wall of the fixing rod 7 are engaged. Therefore, the fixing rod 7 and the connecting block 8 can be inserted together into the sleeve rod 2, causing the connecting block 8 and the connecting groove 3 to engage. Through the engagement of the connecting block 8 and the connecting groove 3, the connection between the fixing rod 7 and the sleeve rod 2 is secure. A first magnet 4 is also installed inside the sleeve rod 2, while the fixing rod 7 is located away from the second sleeve 1. One end of the sleeve 10 is equipped with a second magnet 9. Therefore, when the fixing rod 7 and the sleeve 2 are connected, the first magnet 4 and the second magnet 9 can also attract each other, which makes the connection between the fixing rod 7 and the sleeve 2 more stable. This allows the second connecting disc 6 and the first connecting disc 1 to be spliced ​​together. Then, the end of the wire can be fixed to the outer surface of the sleeve 2. By turning the rocker arm 13, the sleeve 2 can be rotated. The fixing rod 7 and the second sleeve 10 are rotatably connected, so when the sleeve 2 rotates, it will drive the fixing rod 7 to rotate together, and the wire can be wound. The splicing connection makes it easy to store the wire reel, reduces the space occupied, and improves the use effect of the wire reel.

[0019] Example 2: Figure 2 and Figure 4 As shown, based on Embodiment 1, the effect of limiting the winding of the wire is also disclosed, and its specific structure is as follows: The second connecting plate 6 is provided with a limiting structure to limit the wound wire and prevent it from becoming messy. The limiting structure includes a limiting rod 14 that passes through the second connecting plate 6, and the rear end of the limiting rod 14 is connected to the limiting plate 15. A connecting spring 16 is installed between the limiting plate 15 and the second connecting plate 6. The connecting spring 16 is located outside the limiting rod 14, and the limiting rod 14 and the limiting plate 15 are an integral structure. The limiting plate 15 and the mounting rod 11 on the right side do not contact each other. A pressing block 17 is provided between the limiting plate 15 and the second connecting plate 6. The pressing block 17 is U-shaped. The limiting rods 14 are distributed at equal angles, and the limiting rods 14 and the second connecting plate 6 are slidably connected.

[0020] After the wire is wound up, the clamping block 17 is removed from between the second connecting plate 6 and the limiting plate 15. Since a connecting spring 16 is installed between the limiting plate 15 and the second connecting plate 6, the connecting spring 16 is in a stretched state when the clamping block 17 is not removed. Therefore, after the clamping block 17 is removed, the connecting spring 16 will reset, which will cause the limiting rod 14 and the limiting plate 15 to reset together and move closer to the second connecting plate 6. When the limiting rod 14 moves, it will pass through the inside of the second connecting plate 6. Moreover, the limiting rods 14 are evenly distributed, which can limit the wound wire (for wire wound to a certain thickness, the specific winding thickness can be determined according to the actual situation), effectively preventing the wire from becoming loose and messy after winding, ensuring the winding effect. Compared with the traditional fixing method, it is simpler, more convenient and faster, bringing convenience to the staff.
