Description
Technical Field
[0001] This utility model relates to the field of 3D printing equipment, and more particularly to filament reels. Background Technology
[0002] In the field of 3D printing technology, plastic filament is the mainstream printing consumable, and its storage and printing feed usually rely on filament reels. Existing 3D printer filament reels generally adopt an integrated structure of "central cylinder + two fixed baffles on both sides". The central cylinder is used to wind the filament, while the two baffles on both sides play the role of limiting the axial displacement of the filament and preventing the filament from scattering. This structure can meet the basic usage requirements in conventional printing scenarios.
[0003] However, in practical applications, there are significant differences in the length specifications of plastic filaments used in 3D printing (such as 100m, 500m, 1000m, etc.). Different lengths of filament require different amounts of space on the reel. When the filament is long, a larger diameter reel is needed to work with the central cylinder to form sufficient winding space, so as to prevent the filament from overflowing or becoming tangled during winding due to insufficient diameter of the reel. When the filament is short, using a reel with a large diameter reel will result in wasted reel space and inconvenient storage.
[0004] Because the size (especially the diameter) of the existing filament reels is fixed and cannot be adjusted, a single reel size can only accommodate filaments of a specific length. This limitation forces 3D printing users or consumable manufacturers to stock a variety of reels of different sizes, which not only increases procurement costs and storage space, but also requires frequent reel replacements when changing filaments of different lengths. This is cumbersome, affects printing preparation efficiency, and impacts overall portability. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a filament reel with adjustable diameters of the side baffles to accommodate 3D printing filaments of different lengths, thereby improving its ease of use and adaptability.
[0006] This utility model is achieved using the following technical solution: a wire reel, including a cylinder and baffles fixedly disposed on both sides of the cylinder. Multiple sets of storage openings are provided on the outer side of each baffle. Extending plates of matching sizes are slidably stored inside each storage opening. A rotating shaft is rotatably disposed between the two baffles. A turntable is fixedly sleeved on the outer side of the portion of the rotating shaft located within the inner cavity of the baffle. Sliding grooves corresponding to the extending plates are provided on the outer side of each baffle. Arc-shaped grooves corresponding to the extending plates are provided on the outer side of each turntable. A slider that slides in cooperation with the sliding groove is fixedly connected to the outer side of each extending plate. A fixing pin that moves through the arc-shaped groove is fixedly connected to the inner side of each extending plate. Rotating the rotating shaft drives the turntable to rotate. Through the cooperation of the arc-shaped groove and the fixing pin, and the cooperation of the sliding groove and the slider, the extending plates are driven to extend or retract from the storage openings.
[0007] Preferably, the number of the storage opening, extension plate, slide groove and arc groove are all four sets, and the four sets of storage openings are evenly distributed along the circumference of the baffle.
[0008] Preferably, the rotating shaft and the baffle are rotatably connected by a bearing.
[0009] Preferably, one end of the rotating shaft extends to the outside of one of the side baffles and is fixedly connected to a limiting plate. The limiting plate has evenly distributed teeth on its outer side. A limiting frame is fixedly connected to the outside of the side baffle and below the limiting plate. An abutment block is movably disposed inside the limiting frame.
[0010] Preferably, the upper end of the abutment block is an arc-shaped surface, and the arc-shaped surface is uniformly provided with locking teeth that mesh with the locking teeth on the outer side of the limiting plate.
[0011] Preferably, the abutment block is connected to the inner wall of the limiting frame by a spring pin, and the spring pin extends in the default state to make the abutment block abut against the limiting plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model incorporates multiple sets of extension plates at the baffle positions on both sides of the cylinder. The extension plates increase the area of the baffles after they extend, thereby enabling the winding and use of 3D printing filaments of different lengths, thus improving its ease of use and adaptability. Based on this, staff can quickly extend and retract the extension plate by rotating and adjusting the shaft in conjunction with the transmission structure. The operation is very simple and convenient. Based on this, staff can use the limiting plate and limiting frame on the outer end of the shaft to limit the shaft after adjustment, maintain the relative stability of the extension plate after size adjustment, and ensure stable use of the reel.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Please combine Figure 1-4The filament reel consists of a cylinder 1 and baffles 2 on both sides of the cylinder 1. Multiple sets of storage openings 3, preferably four sets, are provided on the outer side of the baffles 2. An extension plate 4 of a matching size is slidably stored inside the storage opening 3. A rotating shaft 5 is rotatably connected between the baffles 2 on both sides and is rotatably connected to the baffles 2 through bearings. By rotating the rotating shaft 5, multiple sets of extension plates 4 are driven to extend out from the storage openings 3 on the outer side of the baffles 2, thereby increasing the area of the baffles 2 and enabling the winding of 3D printed filaments of different lengths.
[0020] The turntable 2 has multiple sets of sliding grooves 21 on its outer side, and the part of the rotating shaft 5 in the inner cavity of the baffle 2 has a turntable 6 fixedly sleeved on its outer side. The turntable 6 has multiple sets of arc-shaped grooves 61 through it. The multiple sets of sliding grooves 21 and arc-shaped grooves 61 correspond one-to-one with the multiple sets of extension plates 4. At the same time, the outer side of the extension plate 4 is fixedly connected to a slider 41, which slides with the sliding groove 21 on the outer side of the baffle 2. The inner side of the extension plate 4 is fixedly connected to a fixing pin 42, which moves through the arc-shaped groove 61 on the outer side of the turntable 6. Based on this setup, when we rotate the shaft 5, the shaft 5 drives the turntable 6 to rotate together. When the turntable 6 rotates, the outer arc groove 61 changes position accordingly, thereby changing the path of the fixing pin 42 inserted into the arc groove 61. This causes the fixing pin 42 and the connected extension plate 4 to move together, allowing the extension plate 4 to slide along the sliding groove 21 on the outside of the baffle 2 via the bottom slider 41. This enables the extension plate 4 to extend from the storage opening 3 on the outside of the turntable 2, increasing the size of the turntable 2 and accommodating more 3D printing filament.
[0021] It should be added that the other end of the rotating shaft 5 extends to the outside of another set of baffles 2 and is fixedly connected to a limiting plate 7. The outer side of the limiting plate 7 is evenly provided with locking teeth. The outer side of the other set of baffles 2 is fixedly connected to a limiting frame 8 at the bottom position of the limiting plate 7. An abutment block 81 is movably disposed inside the limiting frame 8. The abutment block 81 is connected to the inner wall of the limiting frame 8 by a spring pin 82. In its default state, the spring pin 82 extends, causing the abutment block 81 to contact the bottom of the limiting plate 7. The upper end of the abutment block 81 is an arc-shaped surface and evenly distributed... The rotating shaft 5 is evenly provided with locking teeth, which also engage with the locking teeth on the outside of the limiting disk 7. When it is necessary to rotate the rotating shaft 5, the spring pin 82 needs to be pressed down to release the abutment block 81 from the limiting disk 7. After the rotating shaft 5 has rotated and adjusted the size of the baffle 2, the spring pin 82 is released and, under its own elastic restoring force, the abutment block 81 is driven to re-engage with the bottom of the limiting disk 7, thus completing the engagement and limiting, that is, maintaining the relative stability of the rotating shaft 5 after adjustment, which facilitates the relative stability of the baffle 2 and the outer extension block 4 during subsequent use.
[0022] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
[0023] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
