Description

Technical Field

[0001] This utility model relates to the field of material rack technology, and more specifically, to a material rack for a 3D printer. Background Technology

[0002] 3D printing technology refers to the technology of creating three-dimensional entities by continuously stacking physical layers and adding material layer by layer. Unlike traditional material removal processing technology, it is also known as additive manufacturing or additive manufacturing. A 3D material rack is a support specifically used to place 3D printing consumables. It is mainly used to store and support materials used in the 3D printing process, such as PLA, ABS filaments, to ensure material loading stability and make the printing work proceed smoothly.

[0003] Based on the above, the inventors have discovered that existing material racks support the material turntable, leaving the material exposed for extended periods. This exposure makes the outer surface prone to dust accumulation, which can adhere to the printing material, causing defects, unevenness, or spots on the printed surface, affecting the appearance and function of the printed parts. Furthermore, dust can clog the nozzles, leading to blockages or filament breakage during printing, impacting the continuity and stability of the printing process. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a material rack for 3D printers, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a material rack for a 3D printer. This solution is equipped with a cleaning and dust removal component, which can continuously and stably clean the dust adhering to the surface of the material during the feeding process, reduce the problem of dust adhering to the material, improve the subsequent printing effect, and is equipped with a snap-fit ​​component, which can quickly install and disassemble the cleaning and dust removal component, facilitate the replacement of the cleaning and dust removal component in the later stage, and ensure the cleaning effect.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A material rack for a 3D printer includes a support frame. Rotary grooves are provided on both sides near the top of the support frame, and a guide rod is fixedly connected to the center of the front side of the support frame. A guide groove is provided in the middle of the guide rod. Two rotating shafts are symmetrically arranged inside the guide groove. A friction groove is provided in the middle of the rotating shaft, and toothed rings are provided at both ends of the rotating shaft. A pair of snap-fit ​​mechanisms are provided on the outside of the rotating shaft.

[0009] The locking mechanism includes an outer ring, a slider is fixedly connected to the center of the inner side of the outer ring, a positioning rod is fixedly connected to one side of the slider, and a return spring is sleeved on the outer side of the positioning rod.

[0010] Furthermore, the side of the support frame is triangular, the two rotating slots are symmetrically arranged, and the bottom of the rotating slots is semi-circular.

[0011] Furthermore, the toothed ring is located on the inner side of the middle of the guide rod, and the toothed ring is movably connected to the guide rod.

[0012] Furthermore, the connection between the rotating shaft and the gear ring extends through the side of the friction groove, and a cleaning pad is fixedly connected to the outer surface of the friction groove.

[0013] Furthermore, the two toothed rings located on the same side are engaged and connected, and a positioning groove is provided on the inner side of the toothed ring.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) In this solution, the material threads are bonded to the friction groove. During the printing and feeding process, the material threads continuously pass through two rotating shafts. The friction between the material threads and the friction groove causes the rotating shafts to rotate, thereby enabling the cleaning pad to clean the dust on the outer surface of the material. At the same time, the rotation of the rotating shaft drives the corresponding toothed rings to rotate synchronously. Through the cooperation of the two pairs of toothed rings, the rotational stability of the rotating shaft is ensured. Compared with the existing technology, the cleaning and dust removal component can effectively clean the dust adhering to the surface of the material continuously and stably during the feeding process, reduce the problem of dust adhering to the material, and improve the subsequent printing effect.

[0019] (2) By setting up a snap-fit ​​mechanism, the outer ring is first slid inward to make the slider drive the positioning rod into the inside of the rotating shaft. Then the positioning rod is aligned with the positioning groove. The outer ring is released, and under the action of the return spring, the positioning rod moves back to its original position and snaps into the positioning groove. The rotating shaft and the toothed ring are then connected as a whole. Conversely, the outer ring is moved inward to drive the slider to move, so that the outer end of the positioning rod is separated from the positioning groove. The rotating shaft can then be removed for replacement. Compared with the existing technology, the snap-fit ​​component can be set up to quickly install and disassemble the cleaning and dust removal component, which is convenient for the replacement of the cleaning and dust removal component in the later stage and ensures the cleaning effect.

[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A material rack for a 3D printer includes a support frame 1. Rotary grooves 2 are provided on both sides near the top of the support frame 1. A guide rod 3 is fixedly connected to the center of the front side of the support frame 1. A guide groove 4 is provided in the middle of the guide rod 3. Two rotating shafts 5 are symmetrically arranged inside the guide groove 4. A friction groove 6 is provided in the middle of the rotating shaft 5. A toothed ring 7 is provided at both ends of the rotating shaft 5. A pair of snap-fit ​​mechanisms 8 are provided on the outside of the rotating shaft 5.

[0028] The snap-fit ​​mechanism 8 includes an outer ring 11, with a slider 10 fixedly connected in the center inside the outer ring 11. A positioning rod 12 is fixedly connected to one side of the slider 10, and a return spring 13 is sleeved on the outside of the positioning rod 12. The snap-fit ​​mechanism 8 is provided to facilitate the replacement of cleaning components later.

[0029] See Figure 1 The side of the support frame 1 is triangular, the two rotating grooves 2 are symmetrically arranged, and the bottom of the rotating grooves 2 is semi-circular. The turntable containing the material is placed in the middle of the support frame 1, so that the two ends of the turntable are respectively attached to the bottom of the two rotating grooves 2.

[0030] See Figure 2 The toothed ring 7 is located in the middle of the guide rod 3, and the toothed ring 7 is movably connected to the guide rod 3. The rotational stability of the rotating shaft 5 is ensured by the cooperation of two pairs of toothed rings 7.

[0031] See Figure 3 The connection between the rotating shaft 5 and the toothed ring 7 extends through the side of the friction groove 6. A cleaning pad is fixedly connected to the outer surface of the friction groove 6. The material is passed between the two rotating shafts 5 so that the outer surface of the material is in contact with the friction groove 6.

[0032] See Figure 2 Two toothed rings 7 located on the same side are meshed and connected, and a positioning groove 9 is provided on the inner side of the toothed ring 7. During the printing and feeding process, the material continuously passes through the two rotating shafts 5. The friction between the material and the friction groove 6 causes the rotating shafts 5 to rotate, thereby causing the cleaning pad to clean the dust on the outer surface of the material. At the same time, the rotation of the rotating shafts 5 drives the corresponding toothed rings 7 to rotate synchronously.

[0033] See Figure 4 The slider 10 is located in the center inside the rotating shaft 5, and the outer ring 11 is located on the outside of the rotating shaft 5. The connection between the slider 10 and the outer ring 11 is slidably connected to the rotating shaft 5. Moving the outer ring 11 inward will drive the slider 10 to move, so that the outer end of the positioning rod 12 is separated from the positioning groove 9, and the rotating shaft 5 can be removed for replacement.

[0034] See Figure 4 One end of the positioning rod 12 passes through the side of the rotating shaft 5 and is engaged with the positioning groove 9. The two ends of the return spring 13 are fixedly connected to the inner surface of the rotating shaft 5 and the slider 10, respectively. First, slide the outer ring 11 inward so that the slider 10 drives the positioning rod 12 into the interior of the rotating shaft 5. Then, put the rotating shaft 5 into the guide groove 4 so that the positioning rod 12 is aligned with the positioning groove 9. Then, release the outer ring 11. Under the action of the return spring 13, the slider 10 drives the positioning rod 12 to return to its original position. One end of the positioning rod 12 passes through the guide groove 4 and is engaged with the positioning groove 9. Then the rotating shaft 5 and the toothed ring 7 are connected as a whole.

[0035] In use: First, slide the outer ring 11 inward to allow the slider 10 to drive the positioning rod 12 into the interior of the rotating shaft 5. Then, place the rotating shaft 5 into the guide groove 4, aligning the positioning rod 12 with the positioning groove 9. Then, release the outer ring 11. Under the action of the return spring 13, the slider 10 drives the positioning rod 12 to return to its original position. The outer end of the positioning rod 12 passes through the guide groove 4 and engages with the positioning groove 9, thus connecting the rotating shaft 5 and the gear ring 7 into a whole. Then, install the second rotating shaft 5. Next, place the turntable containing the material in the middle of the support frame 1, so that both ends of the turntable are in contact with the bottom ends of the two rotating grooves 2, allowing the material thread to pass between the two rotating shafts 5 and be printed. When the machine's feed inlet is connected, the outer surface of the material comes into contact with the friction groove 6. During the printing and feeding process, the material threads continuously pass through the two rotating shafts 5. The friction between the material threads and the friction groove 6 causes the rotating shafts 5 to rotate, thereby cleaning the dust off the outer surface of the material with the cleaning pad. At the same time, the rotation of the rotating shafts 5 drives the corresponding toothed rings 7 to rotate synchronously. Through the cooperation of the two pairs of toothed rings 7, the rotational stability of the rotating shafts 5 is ensured, effectively cleaning the material threads and improving the printing effect. When the cleaning effect deteriorates, the outer ring 11 is moved inward, causing the slider 10 to move, so that the outer end of the positioning rod 12 is separated from the positioning groove 9, and the rotating shaft 5 can be removed for replacement.
