Description

Technical Field

[0001] This utility model relates to the field of printer spool technology, and in particular to a 3D printing PLA consumable spool with spool management function. Background Technology

[0002] With the widespread application of 3D printing technology, PLA (polylactic acid), as an environmentally friendly and easy-to-process thermoplastic material, has become one of the most commonly used consumables in 3D printing. In actual use, PLA consumables are usually stored and fed in the form of filaments wound on a spool.

[0003] Most cable reels on the market have a simple structure and lack effective cable management functions. This means that people need to wind the loose cables onto the reel one coil at a time. However, winding the cables by hand can result in uneven winding. When used in a printer, this uneven winding can cause unstable tension in the cables during transport, affecting the quality of interlayer bonding and surface finish. Utility Model Content

[0004] The purpose of this invention is to provide a 3D printing PLA consumable spool with a filament management function to solve the above-mentioned problems. This improves upon the previous 3D printing PLA consumable spools with filament management function, which were relatively simple and lacked effective filament management. As a result, personnel had to wind the scattered filaments onto the spool one loop at a time. However, when personnel directly wind the filaments by hand, the filaments would be unevenly wound. When used on a printer, the uneven winding would cause unstable tension of the filaments during transport, affecting the quality of interlayer bonding and surface finish of the printed product.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a 3D printed PLA consumable spool with filament management function, comprising:

[0006] Rotation axis;

[0007] A winding block, which is fixedly connected to the circumferential surface of the rotating shaft;

[0008] Two baffles are respectively fitted onto the circumferential surface of the rotating shaft;

[0009] A threaded rod, which is rotatably connected within two baffles;

[0010] Two pulleys, one of which is fixedly connected to the circumferential surface of the threaded rod, and the other pulley is fixedly connected to the circumferential surface of the rotating shaft, and a belt is meshing between the two pulleys;

[0011] A limiting rod, which is fixedly connected to the adjacent ends of the two baffles;

[0012] A slider, which is slidably connected to the circumferential surface of the threaded rod and the limiting rod;

[0013] A wire hole is provided at one end of the slider and passes through the slider.

[0014] A crank handle, which is fixedly connected to one end of the threaded rod.

[0015] Preferably, the circumferential surface of the winding block is provided with an installation groove, and rotating rods are fixedly connected to the inner walls on both sides of the installation groove. A fixed hook is rotatably connected to the circumferential surface of the rotating rod.

[0016] Preferably, a first limiting block is fixedly connected to the circumferential surface of the threaded rod, and a second limiting block is fixedly connected to the circumferential surface of the rotating shaft.

[0017] Preferably, a nut is fixedly connected to one side of one of the baffles, and a screw is internally threaded into the nut. The screw passes through the crank handle and is threaded into the nut.

[0018] Preferably, an observation window is fixedly connected to one side of one of the baffles.

[0019] Preferably, an anti-slip pad is fixedly connected to the inner circumference of the rotating shaft.

[0020] The beneficial effects of this utility model are:

[0021] 1. This device, through the cooperative structure of the threaded rod and the slider, and the synchronous transmission design of the rotating shaft and the pulley, enables the automatic filament winding function of PLA filament during the winding process. The slider drives the filament to be evenly distributed along the surface of the winding block, avoiding the problems of filament accumulation or loosening caused by uneven winding in traditional manual winding. The uniform winding state can ensure stable tension of the filament during the transportation process, thereby effectively improving the interlayer bonding strength and surface smoothness of the finished product in the 3D printing process, and improving the printing quality.

[0022] 2. This device features an installation groove structure with a fixing hook on the winding block. Before winding, users can make a circular buckle on the end of the wire and insert it into the fixing hook. Then, by rotating the fixing hook, the wire end can be firmly fixed. This design avoids the risk of the wire starting end slipping or loosening in the early stage of winding, improving the safety and stability of operation. It is especially suitable for non-professional users or teaching environments, greatly improving the convenience and practicality of use. Attached Figure Description

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1-5 The present invention provides the following technical solution:

[0032] A 3D printed PLA filament spool with filament management function includes:

[0033] Rotation axis 1;

[0034] Winding block 2 is fixedly connected to the circumferential surface of rotating shaft 1;

[0035] Two baffles 3 are respectively fitted onto the circumferential surface of the rotating shaft 1;

[0036] Threaded rod 4 is rotatably connected to two baffles 3;

[0037] Two pulleys 5, one of which is fixedly connected to the circumferential surface of the threaded rod 4, and the other pulley 5 is fixedly connected to the circumferential surface of the rotating shaft 1. A belt is meshed between the two pulleys 5.

[0038] Limiting rod 6 is fixedly connected to the adjacent ends of the two baffles 3;

[0039] Slider 7 is slidably connected to the circumferential surface of threaded rod 4 and limiting rod 6;

[0040] A wire hole 8 is provided on one side of the slider 7 and passes through the slider 7.

[0041] Crank handle 9 is fixedly connected to one end of threaded rod 4.

[0042] In a specific embodiment of this utility model, the rotating shaft 1, as the core support component of the entire coil, has a hollow structure and is used to install components such as the winding block 2 and baffles 3. It can rotate freely to achieve uniform winding of the wire. The winding block 2 is used to support the winding of the PLA wire. The two baffles 3 prevent the wire from slipping off from both sides, and one of the baffles 3 is hollow inside to accommodate the pulley 5. The threaded rod 4 drives the slider 7 to reciprocate along its direction and the limiting rod 6, thereby achieving automatic wire management. One of the pulleys 5 is fixedly connected to one end of the threaded rod 4, and the other is fixedly connected to one end of the rotating shaft 1. The two pulleys 5 are connected... The belt drive connection enables synchronous movement, ensuring that the rotating shaft 1 and the threaded rod 4 maintain a transmission ratio sufficient for the wire to form a new winding layer on the winding block 2 with each back-and-forth movement of the slider 7. The limiting rod 6 guides and limits the sliding path of the slider 7, ensuring that the slider 7 remains stable and does not deviate during reciprocating motion. The inner wall of the slider 7 is provided with sliding threads, which can move back and forth with the rotation of the threaded rod 4, causing the wire in the threading hole 8 to be evenly distributed on the winding block 2. The threading hole 8 allows the PLA wire to pass through, enabling it to automatically wind under the action of the slider 7. The crank handle 9 allows for manual operation to rotate the threaded rod 4, thereby driving the slider 7 to move and achieve uniform winding of the wire.

[0043] Please refer to the details. Figures 1-5 The circumferential surface of the winding block 2 is provided with an installation groove 10, and the inner walls on both sides of the installation groove 10 are fixedly connected with rotating rods 11, and the circumferential surface of the rotating rods 11 is rotatably connected with fixed hooks 12.

[0044] In this embodiment: the mounting groove 10 is used to install the fixing hook 12, and the rotating rod 11 serves as a fulcrum for the fixing hook 12 to rotate. Before starting the winding process, the operator can tie one end of the PLA wire into a circular knot and then insert the circular knot into the fixing hook 12. By rotating the fixing hook 12 in the mounting groove 10, the operator can clamp the wire and prevent the wire end from coming loose during the winding process, thereby improving the ease of operation and stability and avoiding winding failure due to wire slippage.

[0045] Please refer to the details. Figures 1-5 A first limiting block 13 is fixedly connected to the circumferential surface of the threaded rod 4, and a second limiting block 14 is fixedly connected to the circumferential surface of the rotating shaft 1.

[0046] In this embodiment, the first limiting block 13 and the second limiting block 14 are used to prevent the threaded rod 4 and the rotating shaft 1 from moving axially, and to prevent the belt between the two pulleys 5 from falling off or misaligning, so as to make the overall structure more compact.

[0047] Please refer to the details. Figures 1-5 One of the baffles 3 is fixedly connected to one side end of a nut 15, and a screw 16 is threaded into the nut 15. The screw 16 passes through the crank handle 9 and is threaded into the nut 15.

[0048] In this embodiment, the screw 16 and the nut 15 are threaded together to form a lockable structure. When it is necessary to stop the cable management, the crank handle 9 can be prevented from rotating by tightening the screw 16, making the overall device the same as a regular cable reel. Personnel can directly connect this device to the printer and use it.

[0049] Please refer to the details. Figures 1-5 One of the baffles 3 has an observation window 17 fixedly connected to one side.

[0050] In this embodiment: the observation window 17 covers part of the area of ​​the baffle 3. Personnel can directly see the status of the wire on the winding block 2 through the observation window 17 and check the remaining status of the wire, so as to facilitate timely replacement.

[0051] Please refer to the details. Figures 1-5 An anti-slip pad 18 is fixedly connected to the inner circumference of the rotating shaft 1.

[0052] In this embodiment: the anti-slip pad 18 can effectively increase the friction between the printer's connecting shaft and the drive shaft 1 when the spool is installed on the printer's cable feeding mechanism, thus preventing slippage.

[0053] The operator makes a circular buckle at one end of the PLA wire, opens the fixing hook 12, inserts the circular buckle into the fixing hook 12, and rotates the fixing hook 12 to clamp the wire, ensuring that the starting end of the wire is firmly fixed on the winding block 2. The operator then loosens the screw 16, releases the locking state of the crank handle 9, evenly holds the end of the wire, and slowly turns the crank handle 9, causing the threaded rod 4 to rotate. Simultaneously, the rotation of the threaded rod 4, through the transmission action of the pulley 5 and the belt, drives the rotating shaft 1 to rotate synchronously. Because the distance between the two pulleys 5 is sufficient for the slider 7 to move back and forth each time, allowing the wire to form a new winding layer on the winding block 2, the movement speed of the slider 7 is synchronized with the rotation speed of the rotating shaft 1. The device achieves rapid matching and uniform wire winding. As the threaded rod 4 rotates, the slider 7 moves back and forth along the direction of the threaded rod 4 and the limiting rod 6 under the action of its threaded structure. The PLA wire passing through the wire hole 8 is evenly distributed on the surface of the winding block 2 as the slider 7 moves. The first limiting block 13 and the second limiting block 14 respectively restrict the axial movement of the threaded rod 4 and the rotating shaft 1 to prevent the belt from falling off or misaligning. The limiting rod 6 guides the sliding path of the slider 7 to ensure its stable operation. When the wire is completely wound, stop turning the crank 9 and tighten the screw 16 and nut 15 to lock the entire device in a locked state. It can then be used as a regular wire reel in a printer.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
