[0002] With the continuous development of technology, 3D printing has become a hot topic in many fields such as manufacturing, medicine, and education. One of the core aspects of 3D printing technology is the filaments, which directly affect the quality and effect of 3D printing. 3D printing filaments are the materials used in 3D printing. They are typically made of specific polymers or other materials, which are stacked layer by layer through melting or solidification to ultimately form a complete three-dimensional object.

[0003] A prior art patent, CN221745802U, discloses a 3D printing consumable testing device. This patent includes a fixed frame with a driving mechanism. The driving mechanism includes a vertical driving component, which includes a guide rod. A test block is also fixedly mounted on the fixed frame. The device further includes a feeding component, which includes a feeding tray with a consumable coil wound on it. A test nozzle is slidably mounted on the guide rod, and a heating component for hot-melting the printing consumable is fixedly mounted on the test nozzle. A testing platform is mounted on the fixed frame. Furthermore, a sliding block is fixedly provided at the bottom of the test platform, and the sliding block is slidably connected to the fixed frame; the test component is set on the fixed frame and located above the test platform, which can realize the conveying and processing of consumables, and can also realize the spraying and testing of printing consumables. However, in actual use, there are still the following shortcomings: From a practical point of view, when the printing consumables are conveyed for testing, this patent cannot perform the operation of conveying and limiting the printing consumables according to the process of the test work, which can easily lead to deviations in the conveying process of printing consumables and affect the smooth progress of the test work.

[0004] Therefore, a 3D printing consumable testing device is needed to solve the problem in existing technologies that cannot perform delivery and limiting protection operations on printing consumables according to the testing process. Utility Model Content

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Please see Figure 1-4This utility model provides a 3D printing consumable testing device, including a fixed frame 1, a vertical drive device 2, a drive base 3, a feeding device 4, a testing platform 5, and a testing device 6. The vertical drive device 2 is fixedly installed on the upper part of the fixed frame 1, the drive base 3 is disposed on the vertical drive device 2, the testing platform 5 is installed on the top of the fixed frame 1, and the testing device 6 is disposed on the vertical drive device 2 through the drive base 3. A filament 402 is wound on the feeding device 4, and a test block 401 is disposed on the filament 402 and rotatably connected to the vertical drive device 2. The filament 402 is connected to the testing device 6 through the test block 401. The testing device 6 includes a driver 601 and a test nozzle 602. The driver 601 is disposed on the vertical drive device 2 through the drive base 3 and is connected to the filament 402. The test nozzle 602 is connected to the driver 601. A feeding protection mechanism 7 is disposed on the upper part of the driver 601 for limiting and protecting the feeding process of the filament 402.

[0021] The fixed frame 1, vertical drive device 2, drive base 3, feeding device 4, test platform 5 and test device 6 have been specifically disclosed in the patent with patent publication number CN221745802U, and will not be elaborated further here.

[0022] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the feeding protection mechanism 7 includes two fixed frames 701. The fixed frames 701 have a C-shaped cross-section. The two fixed frames 701 are symmetrically fixed on the top of the driver 601 and on both sides of the wire 402. A first connecting rod 702 is rotatably mounted inside the fixed frame 701 near the wire 402. A first rotating shaft 7011 is rotatably connected to the bottom end of the first connecting rod 702. The first connecting rod 702 is rotatably mounted on the fixed frame 701 through the first rotating shaft 7011. A second rotating shaft 7012 is rotatably connected to the other end of the first connecting rod 702. A guide block 703 is rotatably connected to the upper end of the first connecting rod 702 through the second rotating shaft 7012. A feeding groove 704 is provided on the side of the guide block 703 near the wire 402. The side surface of the wire 402 is provided with an anti-slip pad 705. The bottom surface of the first connecting rod 702 is fixedly connected to a first hinge seat 706. A support rod 707 is hingedly installed on the first hinge seat 706. A second hinge seat 709 is hingedly installed at the bottom end of the support rod 707. A second connecting rod 708 is fixedly connected to the bottom of the second hinge seat 709. A third rotating shaft 7013 is rotatably connected to the upper end of the second connecting rod 708. The second connecting rod 708 is rotatably connected to the fixed frame 701 through the third rotating shaft 7013 and is located below the first connecting rod 702. A guide roller 7010 is rotatably installed at the end of the second connecting rod 708 near the wire 402. The guide roller 7010 is attached to the surface of the wire 402 through the second connecting rod 708. The guide roller 7010 is made of silicone material.

[0023] In use, wire 402 is conveyed inside the anti-slip pad 705, with guide roller 7010 adhering to its surface for positioning. This ensures uniformity and stability in the conveying process of wire 402, thereby improving the accuracy of testing. When wire 402 stops conveying, the guide roller 7010 is subjected to the retraction force from the surface of wire 402, causing the second connecting rod 708 to rotate at a certain angle via the third rotating shaft 7013. This allows the guide roller 7010 to press and limit the surface of wire 402, thus stabilizing wire 402 and preventing it from retracting. Simultaneously, the support rod 707, in conjunction with the first connecting rod 702, ensures the stability of the wire 402's position through the guide block 703, facilitating conveying tests and improving the stability of the device during use.

[0024] This solution has the following working process: When this device is in use, the wire 402 is connected to the driver 601 through the test block 401, which facilitates the conveying test. Furthermore, the test nozzle 602 and the test platform 5 allow for testing the wire 402 during its conveying and spraying process. Simultaneously, the vertical drive device 2, in conjunction with the sliding of the drive base 3, facilitates the adjustment of the test device 6, improving the device's practicality. The fixed frame 1, vertical drive device 2, drive base 3, feeding device 4, test platform 5, and test device 6 have been specifically disclosed in patent publication number CN221745802U; their testing work and operating principles will not be elaborated further here. During the conveying process of the wire 402, the wire... 402 is conveyed inside the anti-slip pad 705, and is limited by the guide roller 7010 that adheres to its surface, so that the conveying process of wire 402 can maintain uniformity and stability, thereby improving the accuracy of its testing. When the wire 402 stops conveying, the guide roller 7010 is subjected to the retraction force of the surface of the wire 402, so that the second connecting rod 708 rotates at a certain angle through the third rotating shaft 7013, thereby making the guide roller 7010 squeeze and limit the surface of the wire 402, thus keeping the wire 402 stable and preventing it from retracting. At the same time, the support rod 707 is set in conjunction with the first connecting rod 702, and the guide block 703 can ensure the stability of the position of the wire 402, so as to facilitate the conveying test and improve the stability of the device during use.

[0025] In summary: By using the feeding protection mechanism 7, the device can limit the movement of the filament 402 in real time according to its feeding status during the testing process, thereby effectively preventing the feeding filament 402 from retracting, thus improving the stability of the feeding process and maintaining uniformity in the feeding process, which facilitates testing operations and improves the accuracy of the test.
