Abstract
Description
Technical Field
[0001] This invention belongs to the field of 3D printing technology, specifically relating to a stable material-guided 3D printing device. Background Technology
[0002] With the continuous development of 3D printing technology, its applications in manufacturing, healthcare, education, and many other fields are becoming increasingly widespread. 3D printers can directly create three-dimensional solid objects based on digital model files, a process that typically involves stacking materials layer by layer. For 3D printing equipment, a stable supply of consumables is one of the key factors in ensuring print quality and efficiency.
[0003] Most 3D printing equipment currently on the market uses a single filament supply system, meaning it can only process one type of filament at a time. While this design is simple in structure, it presents some problems in practical use:
[0004] Because only one type of filament can be used for printing at a time, this not only affects work efficiency but also increases operational complexity. Secondly, some existing 3D printing equipment is prone to filament misalignment or jamming during the feeding process, especially during long-term continuous operation. The filament may deform due to temperature changes or other external factors, leading to printing failure or quality degradation. Furthermore, filaments of different brands or models often have different physical properties such as diameter and hardness. Traditional single-chamber designs are difficult to flexibly adjust to meet the needs of various filaments, limiting the application range of the equipment. Utility Model Content
[0005] The purpose of this invention is to provide a stable feeding 3D printing device that can solve the problems existing in the material supply process of current 3D printing devices, such as material offset, jamming, and insufficient adaptability to materials of different diameters.
[0006] The specific technical solution adopted in this utility model is as follows:
[0007] A stable material-guided 3D printing device includes a main body, with a material guide box at the upper end of the main body, and the material guide box is divided into two chambers.
[0008] The discharge port is located at the upper end of the guide box, and the inlet port is located at the lower end of the guide box.
[0009] The first limiting mechanism, the two first limiting mechanisms are respectively disposed at the lower ends of the two chambers inside the guide box;
[0010] The second limiting mechanism is located at the lower end of the two chambers inside the guide box.
[0011] The second limiting mechanism includes a fixed roller, which is rotatably connected inside the guide box. The guide box is also provided with a clamping part, and the clamping part is provided with an adjustment part.
[0012] In a preferred embodiment, the first limiting mechanism includes a vertical plate arranged in a ring at the feed hole, and the vertical plate is fixedly connected to the guide box. A guide rod is slidably inserted into the vertical plate, and a clamping plate is fixedly connected to one end of the guide rod. A spring is sleeved on one end of the guide rod.
[0013] In a preferred embodiment, the clamping part includes a U-shaped seat, which is disposed on one side of the fixed roller, and a clamping roller is rotatably connected to the U-shaped seat.
[0014] In a preferred embodiment, the adjusting part includes a threaded rod threadedly connected to the guide box. One end of the threaded rod is rotatably connected to a movable plate, and the other end of the threaded rod is fixedly connected to a torsion wheel. A movable rod is slidably inserted into the movable plate, and one end of the movable rod is fixedly connected to the movable plate. A compression spring is sleeved on one end of the movable rod. A sliding groove is formed on the inner wall of the guide box, and a slider is slidably connected in the sliding groove and fixedly connected to the movable plate.
[0015] In a preferred embodiment, a plurality of clamping plates are arranged in a circle, and ball bearings are provided on the clamping plates.
[0016] In a preferred embodiment, the diameters of both the fixed roller and the clamping roller gradually decrease from both ends to the middle.
[0017] The technical effects achieved by this utility model are as follows:
[0018] This utility employs a dual-chamber design, allowing for the simultaneous processing of two different consumables, significantly improving printing efficiency. Users can use multiple materials in the same print job, enhancing printing flexibility and versatility.
[0019] This utility model effectively limits the movement of consumables during the feeding process through the dual action of the first and second limiting mechanisms, ensuring stable and orderly delivery to the discharge port. Furthermore, the design of the clamping and adjusting parts allows the consumables to be properly clamped regardless of their thickness, preventing deformation and jamming caused by temperature changes or other external factors, thereby improving print quality.
[0020] This utility model, through its flexible structural design (such as springs) and the fine-tuning function of the adjustment mechanism, can accommodate consumables of different diameters and hardnesses. Each chamber's second limiting mechanism is equipped with an independent adjustment section, allowing for adjustments based on actual needs, ensuring that different types of consumables can be effectively clamped and transported. This not only expands the equipment's application range but also reduces printing failures caused by consumable incompatibility. Attached Figure Description

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.
[0036] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.
[0037] Please see the appendix Figures 1-6 As shown, this utility model provides a stable material guiding 3D printing device, including a device body 1, a material guiding box 2 is provided at the upper end of the device body 1, and the material guiding box 2 is divided into two chambers;
[0038] The discharge hole 3 is located at the upper end of the guide box 2, and the feed hole 4 is located at the lower end of the guide box 2.
[0039] The first limiting mechanism 5, the two first limiting mechanisms 5 are respectively set at the lower ends of the two chambers inside the guide box 2;
[0040] The second limiting mechanism 6 is located at the lower end of the two chambers inside the guide box 2.
[0041] The second limiting mechanism 6 includes a fixed roller 61, which is rotatably connected to the guide box 2. The guide box 2 is also provided with a clamping part 62, and the clamping part 62 is provided with an adjusting part 63.
[0042] In this embodiment, a first limiting mechanism 5 is installed at the lower end of both chambers. The main function of this mechanism is to restrict the movement of consumables within the chambers, ensuring that they are stably and orderly conveyed to the discharge port 3.
[0043] The second limiting mechanism 6 is also located at the lower end of the two chambers, complementing the first limiting mechanism 5. Specifically, the second limiting mechanism 6 includes a fixed roller 61, which is tightly connected to the guide box 2 via a rotatable connection, effectively assisting in the guidance and limiting of consumables. Furthermore, the guide box 2 is also equipped with a clamping part 62, on which an adjusting part 63 is mounted for fine-tuning according to actual needs.
[0044] Each chamber is equipped with a first limiting mechanism 5 and a second limiting mechanism 6. The dual-chamber design of the guide box 2 allows two consumables to be guided simultaneously and independently, greatly improving the flexibility and printing efficiency of the equipment.
[0045] In a preferred embodiment, please refer to Figure 6 The first limiting mechanism 5 includes a vertical plate 501, which is arranged in a ring at the feed hole 4 and is fixedly connected to the guide box 2. A guide rod 502 is slidably inserted on the vertical plate 501. A clamping plate 503 is fixedly connected to one end of the guide rod 502, and a spring 504 is sleeved on one end of the guide rod 502.
[0046] In this embodiment, when replacing consumables, the consumables are accurately introduced through the feed hole 4. Subsequently, during the feeding process, the consumables cause multiple clamping plates 503 to displace and separate from each other. This action simultaneously guides the guide rod 502 to move and compresses the spring 504 to store potential energy. The reaction force released by the spring 504 after compression drives the multiple clamping plates 503 to move in the opposite direction and move closer to each other, thereby achieving a stable clamping of the consumables.
[0047] Furthermore, by designing this flexible structure, the device exhibits broad adaptability to consumables of different diameters, enabling effective clamping and guiding operations.
[0048] Secondly, please refer to again Figure 4 and Figure 5 The clamping part 62 includes a U-shaped seat 621, which is disposed on one side of the fixed roller 61, and a clamping roller 622 is rotatably connected to the U-shaped seat 621.
[0049] In this embodiment, the consumable is guided to the second limiting mechanism 6 via the first limiting mechanism 5. Subsequently, through the coordinated action of the clamping roller 622 and the fixed roller 61 on the second limiting mechanism 6, the consumable is stably clamped and limited.
[0050] Secondly, please refer to the following as well. Figure 4 and Figure 5The adjusting part 63 includes a threaded rod 631, which is threadedly connected to the guide box 2. One end of the threaded rod 631 is rotatably connected to a movable plate 632, and the other end of the threaded rod 631 is fixedly connected to a torsion wheel 633. A movable rod 634 is slidably inserted into the movable plate 632, and one end of the movable rod 634 is fixedly connected to the movable plate 632. A compression spring 635 is sleeved on one end of the movable rod 634. A sliding groove 636 is provided on the inner wall of the guide box 2, and a slider 637 is slidably connected in the sliding groove 636. The slider 637 is fixedly connected to the movable plate 632.
[0051] In this embodiment, after the consumable passes between the clamping roller 622 and the fixed roller 61, the rotating torsion wheel 633 drives the threaded rod 631 to rotate, thereby pushing the moving plate 632 and the U-shaped seat 621 to move in a predetermined direction until the clamping roller 622 and the fixed roller 61 on the U-shaped seat 621 clamp the consumable. This clamping mechanism relies on the cooperative action of the clamping roller 622 and the U-shaped seat 621.
[0052] During printing, the traction structure on the print head applies tension, causing the filament to move upwards along a predetermined path (this is an existing structure on the printing equipment; those skilled in the art should be familiar with its specific working principle and structure, and will not be elaborated further here), and causing the clamping roller 622 and the fixed roller 61 to rotate accordingly. In the non-printing state, the filament is stationary. At this time, the clamping roller 622 and the fixed roller 61 firmly hold the filament to prevent it from falling off the print head and then from dropping from the feed box 2, thus avoiding the tedious step of repeatedly threading the filament.
[0053] In addition, to meet the clamping requirements of consumables of different thicknesses, each chamber's second limiting mechanism 6 is equipped with an independent adjustment part 63 to ensure that two consumables of different thicknesses can be fixed at the same time.
[0054] Furthermore, the moving rod 634 on the U-shaped seat 621 is connected to the moving plate 632 by a plug-in connection, and with the addition of the compression spring 635, the clamping roller 622 is given a certain amount of room to move, so as to prevent excessive clamping from causing the consumables to jam.
[0055] Secondly, please refer to the following: Figure 4 and Figure 5 Multiple clamping plates 503 are arranged in a circle, and ball bearings are provided on the clamping plates 503.
[0056] In this embodiment, multiple clamping plates 503 can wrap the consumables, serving as guides and limiters. The clamping plates 503 are equipped with ball bearings, which can reduce the friction between the consumables and the clamping plates 503, thereby ensuring the smoothness of feeding.
[0057] Secondly, please refer to again Figure 4The diameters of both the fixed roller 61 and the clamping roller 622 exhibit a gradual decreasing trend from both ends towards the middle. This design aims to ensure that the consumables are securely clamped in the middle position of the two rollers, thereby effectively preventing them from falling off or shifting during operation and ensuring the stability and reliability of the equipment operation.
[0058] The working principle of this utility is as follows:
[0059] Dual-chamber design:
[0060] The feed box 2 is divided into two independent chambers, each of which is equipped with a discharge port 3 and a feed port 4.
[0061] Each chamber is equipped with a first limiting mechanism 5 and a second limiting mechanism 6 at its lower end to ensure that two different types of consumables can be guided and transported simultaneously and independently.
[0062] First limiting mechanism 5:
[0063] The first limiting mechanism 5 includes a vertical plate 501, which is arranged in a ring at the feed hole 4 and is fixedly connected to the guide box 2.
[0064] A guide rod 502 is slidably inserted into the vertical plate 501. One end of the guide rod 502 is fixedly connected to a clamping plate 503, and the other end is fitted with a spring 504.
[0065] When the consumable is introduced through the feed hole 4, the multiple clamping plates 503 will separate from each other under the push of the consumable, and the compressed spring 504 will store potential energy. Subsequently, the spring 504 releases the reaction force, causing the clamping plates 503 to come closer together again, thus achieving a stable clamping of the consumable.
[0066] Second limiting mechanism 6:
[0067] The second limiting mechanism 6 includes a fixed roller 61, which is rotatably connected inside the guide box 2 to assist in guiding and limiting the consumables.
[0068] The clamping part 62 includes a U-shaped seat 621, on which a clamping roller 622 is rotatably connected.
[0069] The adjusting part 63 includes a threaded rod 631, which is threadedly connected to the guide box 2. One end of the threaded rod 631 is rotatably connected to a moving plate 632, and the other end is fixedly connected to a torsion wheel 633.
[0070] A moving rod 634 is slidably inserted into the moving plate 632. A compression spring 635 is sleeved on one end of the moving rod 634. A groove 636 is opened on the inner wall of the guide box 2. A slider 637 is slidably connected in the groove 636. The slider 637 is fixedly connected to the moving plate 632.
[0071] The rotating torsion wheel 633 drives the threaded rod 631 to rotate, which in turn pushes the moving plate 632 and the U-shaped seat 621 to move until the clamping roller 622 and the fixed roller 61 clamp the consumable.
[0072] During printing, the traction structure on the print head pulls the filament, causing it to move upward along a predetermined path, which in turn drives the clamping roller 622 and the fixed roller 61 to rotate. In non-printing mode, the clamping roller 622 and the fixed roller 61 hold the filament securely, preventing it from falling off the print head.
[0073] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
