Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology, specifically to a traction and storage device for flexible 3D printing consumables. Background Technology

[0002] With the rapid development and widespread application of 3D printing technology, flexible 3D printing filaments have become one of the most important materials in the 3D printing field due to their unique flexibility, ductility, and diverse application scenarios. Flexible 3D printing filaments can be used to manufacture items with flexibility, elasticity, and deformability, and are widely used in industries such as medical, construction, clothing, footwear, and consumer goods. In the production process of flexible 3D printing filaments, the traction and storage stages are key steps to ensure filament quality and production efficiency.

[0003] However, existing flexible 3D printing filament traction devices mainly use traditional hard extrusion rollers to pull the filament out. Because flexible filaments have significant flexibility and elasticity, they are prone to deformation during high-speed traction, causing them to bounce from side to side, sometimes even running off the rollers or getting caught in the shaft, resulting in equipment damage and production interruptions. Furthermore, existing storage devices typically only have a single storage container, requiring frequent manual container changes, which not only increases labor costs and reduces production efficiency but also easily leads to cross-contamination and damage to the filaments.

[0004] Therefore, there is an urgent need for a traction and storage device that can adapt to the characteristics of flexible 3D printing consumables. It should have an adaptive buffer function to prevent the consumables from deforming and deviating during high-speed traction; at the same time, it should have an automatic storage function that can automatically switch storage containers according to the preset length, reduce manual intervention, and improve production efficiency and product quality.

[0044] Please see Figure 1-7 This utility model provides a technical solution: a traction and storage device for flexible 3D printing consumables, comprising:

[0045] The first platform 1;

[0046] Two sets of side supports 3 are fixedly installed at intervals on the top of the first platform 1. Two sets of guide rods 4 are fixedly connected to the top of the side supports 3. Upper adjustment blocks 7 are movably sleeved on the two sets of guide rods 4. Bearings 11 are fixedly embedded in the inner side of the upper adjustment blocks 7. The upper end of the guide rods 4 is fixedly connected to the top 5. The top of the top 5 is equipped with a PLC control system 6. Two sets of first lower traction rollers 8 are provided between the two sets of side supports 3. Both ends of the first lower traction rollers 8 are connected to the two sets of side supports 3 through the first fixed bearing seats 9. A first upper traction roller 10 is provided directly above the first lower traction roller 8. Both ends of the first upper traction roller 10 are fixed in the inner ring of the bearing 11 that it is close to. A proximity sensor 29 is installed on one set of side supports 3, and a detection iron column 30 is fixedly connected to one set of first lower traction rollers 8.

[0047] The second platform 2 is set on one side of the first platform 1, and a turntable motor 26 is fixedly installed on the top of the second platform 2;

[0048] Two main support brackets 12 are fixedly connected to the two side support brackets 3 on the side near the second platform 2. A second lower traction roller 13 and a second upper traction roller 14 are provided between the two main support brackets 12. The second lower traction roller 13 is located directly below the second upper traction roller 14, and both ends of the second lower traction roller 13 are connected to the two main support brackets 12 through the second fixed bearing seat 15. A transmission toothed wheel 24 is fixedly connected to one end of the second lower traction roller 13. An adjustment mechanism is provided on the main support bracket 12, and both ends of the second upper traction roller 14 are respectively connected to the two adjustment mechanisms.

[0049] The drive motor 22 is fixed on one of the first fixed bearing seats 9. The motor shaft of the drive motor 22 is fixedly connected to one of the first lower traction rollers 8. The motor shaft of the drive motor 22 is fixedly connected to the drive toothed wheel 23. A toothed belt 25 is provided between the drive toothed wheel 23 and the transmission toothed wheel 24.

[0050] The turntable frame 27 is fixedly connected to the motor shaft of the turntable motor 26. Several sets of storage bins 28 are connected in a regular circular array on the turntable frame 27. The storage bins 28 are suitable for collecting consumables.

[0051] Among them, the first lower traction roller 8, the first upper traction roller 10, the second lower traction roller 13, and the second upper traction roller 14 are suitable for traction and conveying consumables, and the adjustment mechanism is suitable for adaptively adjusting the position of the second upper traction roller 14.

[0052] Specifically, during use, the position of the upper adjusting block 7 can be adjusted on the guide rod 4, and the upper adjusting block 7 can be fastened to the guide rod 4 with bolts.

[0053] Specifically, the combined design of the first platform 1 and the second platform 2 achieves an organic integration of the traction system and the storage system. The cooperation of the two sets of first lower traction rollers 8 and first upper traction rollers 10 forms the primary traction zone, which can stably pull the flexible consumables out of the extrusion equipment; while the second lower traction roller 13 and second upper traction roller 14 constitute the secondary traction zone, further ensuring the stability of consumable transmission. In particular, the cooperation of the second upper traction roller 14 with the adjustment mechanism realizes an adaptive buffer function, using elastic pressure rather than hard extrusion to traction the flexible consumables, effectively avoiding the deformation and lateral jumping of the consumables during high-speed traction, and preventing the consumables from running out of the rollers and getting caught in the shaft.

[0054] Specifically, the drive motor 22, through the transmission system formed by the active toothed pulley 23, the toothed belt 25, and the transmission toothed pulley 24, ensures the synchronous operation of each traction roller, improving the stability and consistency of the traction process. In use, the drive motor 22 drives the active toothed pulley 23 and the first lower traction roller 8 in the middle group to rotate synchronously, and then drives the transmission toothed pulley 24 and the second lower traction roller 13 to rotate through the toothed belt 25.

[0055] The PLC control system 6 is electrically connected to the turntable motor 26 and the proximity sensor 29. Specifically, the PLC control system 6, model LJ12A3-4-Z / BX, serves as the core control unit. It receives signals from the proximity sensor 29, accurately calculates the number of rotations of the traction roller, and converts this into the length of the consumable. When the consumable reaches the preset length, the PLC control system 6 automatically sends a control signal to the turntable motor 26, driving the turntable motor 26 to rotate the turntable frame 27, moving the next empty storage bin 28 to the consumable outlet position, thus achieving automatic switching of the storage bins. This intelligent control method requires no manual intervention, greatly reducing the workload of operators, avoiding errors and delays that may be caused by manual operation, and ensuring the continuity and stability of the production process. Simultaneously, the programmable nature of the PLC control system 6 allows the equipment to flexibly adjust parameters such as storage length and switching time according to different types of flexible consumables and different production requirements, enhancing the adaptability and versatility of the equipment. Furthermore, the non-contact detection method of the proximity sensor 29 avoids contamination and damage that may be caused by direct contact with the consumables, ensuring the cleanliness and quality of the product.

[0056] Reference manual attached Figure 2-5 The regulating mechanism includes:

[0057] The lower optical axis seat 16 is fixed on the main body bracket 12;

[0058] The upper optical axis seat 17 is fixed on the main body bracket 12 and is positioned above the lower optical axis seat 16.

[0059] Two sets of optical axis guide rails 18 are fixed between the lower optical axis seat 16 and the upper optical axis seat 17;

[0060] Slider 19 is movably mounted on two sets of optical axis guide rails 18;

[0061] The third fixed bearing seat 20 is fixed on the slider 19, and both ends of the second upper traction roller 14 are rotatably mounted on the third fixed bearing seat 20.

[0062] Two sets of springs 21 are fixed between the upper optical axis seat 17 and the slider 19, and the two sets of springs 21 are respectively sleeved on the outside of the two sets of optical axis guide rails 18.

[0063] Specifically, the adjustment mechanism constitutes a precise adaptive buffer system. Two sets of optical axis guide rails 18 are vertically arranged to ensure that the slider 19 can move smoothly in the vertical direction, providing precise guidance for the position adjustment of the second upper traction roller 14. The slider 19 is sleeved on the optical axis guide rail 18 and can slide freely up and down. The third fixed bearing seat 20 is fixed on the slider 19, supporting both ends of the second upper traction roller 14, so that the second upper traction roller 14 can move together with the slider 19. Two sets of springs 21 provide downward elastic pressure for the slider 19 and the second upper traction roller 14 on it. This elastic pressure mechanism is different from the traditional hard extrusion method. It can automatically adjust the pressure according to the thickness and hardness of the consumable. When the flexible consumable passes through, the second upper traction roller 14 will apply appropriate pressure to the consumable under the action of the springs 21 to form a soft extrusion effect. During high-speed traction, if the consumable undergoes slight deformation or thickness change, the springs 21 will automatically adjust the height position of the second upper traction roller 14 to provide buffer space for the consumable, prevent the consumable from deforming excessively due to hard extrusion, and effectively avoid the problem of the consumable jumping left and right and running off-center. Meanwhile, the elastic properties of spring 21 can absorb vibrations and impacts during traction, further improving the smoothness and continuity of the traction process. This adaptive adjustment mechanism greatly enhances the equipment's ability to handle different types of flexible consumables and solves the technical challenge of high-speed traction of flexible materials.

[0064] Reference manual attached Figure 1 and instruction manual attached Figure 6 The turntable frame 27 includes:

[0065] Lower support frame 2701;

[0066] The upper mounting bracket 2702 is fixed above the lower support bracket 2701 by a bracket. The upper mounting bracket 2702 has several sets of mounting ports 2703 arranged in a regular ring array.

[0067] The storage bucket 28 passes through the mounting port 2703 and is connected to the top of the lower support frame 2701. The outer diameter of the storage bucket 28 is matched with the inner diameter of the mounting port 2703.

[0068] Specifically, this layered turntable frame 27 design optimizes the installation and replacement of the collection bins 28. Several sets of mounting ports 2703 provide standardized installation positions for the collection bins 28, ensuring that they are evenly distributed around the turntable and preventing them from shaking or falling off during rotation. This double-layer support structure also facilitates the installation and removal of the collection bins 28, allowing operators to easily remove full collection bins 28 and replace them with empty ones, improving work efficiency. Simultaneously, the circular array layout ensures uniform spacing between the collection bins 28 and a consistent turntable rotation angle, facilitating precise control of the turntable's rotation position by the PLC control system 6, ensuring that empty collection bins 28 are accurately aligned with the consumable outlet position each time.

[0069] Reference manual attached Figure 3 and instruction manual attached Figure 7 The detection columns 30 are arranged in a regular circular array of four groups. The end of each detection column 30, away from the first lower traction roller 8, rotates to approach the probe of the proximity sensor 29. Specifically, the four groups of detection columns 30 arranged in a regular circular array constitute a high-precision consumable length measurement system. The detection columns 30 are fixedly mounted on the first lower traction roller 8 and rotate with the traction roller. Each rotation causes the four groups of detection columns 30 to pass through the detection area of ​​the proximity sensor 29 four times, triggering a signal four times. Since the detection columns 30 are evenly distributed on the circumference of the first lower traction roller 8, when each detection column 30 passes the proximity sensor 29, it indicates that the first lower traction roller 8 has rotated a quarter turn, corresponding to the pulling out of a certain length of consumable. By calculating the number of times the detection columns 30 trigger the proximity sensor 29, the PLC control system 6 can accurately calculate the total length of the pulled consumable. This multi-point detection method greatly improves the accuracy and resolution of length measurement compared to single-point detection, enabling more precise control of the length of consumables in each storage bin 28 and ensuring product specification consistency. In particular, the evenly distributed design of the four sets of detection iron pillars 30 enables precise detection of the traction roller every 1 / 4 revolution, effectively increasing the accuracy of single-revolution detection by four times. This 1 / 4 revolution multiplier detection mechanism allows the system to measure consumables in smaller length units, significantly improving measurement accuracy and resolution. For example, if the circumference of the first lower traction roller 8 is 120 mm, traditional single-point detection can only use 120 mm as the smallest detection unit. However, with the four sets of detection iron pillars 30 in this design, the smallest detection unit is reduced to 30 mm, making length control more precise. This design also allows for flexible adjustment of detection accuracy by simply increasing or decreasing the number of detection iron pillars 30, meeting the production needs of different accuracy requirements and enhancing the adaptability and versatility of the equipment.
