Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing platform leveling mechanism with vibration compensation. Background Technology

[0002] In its early days, 3D printers were mainly used for prototyping in the industrial field. Due to their high cost and complex operation, their application scope was limited. After the 21st century, with the development of open source technology and materials science, the cost of equipment dropped significantly. 3D printers gradually extended from industrial-grade to consumer-grade and desktop-grade, and their application scenarios expanded to fields such as medical care, construction, and education. They have become a core tool for connecting digital models and physical entities, driving the transformation of the manufacturing industry from "subtractive manufacturing" to "additive manufacturing on demand".

[0003] The core structure of a 3D printer includes a control system, an actuator, a transmission system, and a feeding device. The software slices the 3D model into multiple two-dimensional sections. The control system drives the actuator to move along the slicing path, while the feeding device delivers material. The material is melted by the nozzle or cured by laser to form a single-layer structure. The layers are bonded together by temperature or chemical action, and finally stacked to form a complete three-dimensional entity.

[0004] During the use of a 3D printer, the print head can vibrate when it comes into contact with the printing platform. Due to the lack of a rapid leveling function with vibration compensation, the printing platform may shift due to vibration, resulting in deviations in the printed object. Therefore, a 3D printing platform leveling mechanism with vibration compensation is proposed to solve the above problem. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a 3D printing platform leveling mechanism with vibration compensation, aiming to improve the problem of the lack of a rapid leveling function with vibration compensation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vibration-compensated 3D printing platform leveling mechanism includes a base plate. Two sliding grooves are fixedly connected to the top of the base plate. Two sliding blocks are slidably connected inside each of the two sliding grooves. A support plate is fixedly connected to the top of each sliding block. Multiple threaded posts are threadedly connected inside the support plate. Rotating handles are fixedly connected to the bottom of each of the multiple threaded posts. Limit blocks are rotatably connected to the top of each threaded post. A damper is fixedly connected to the top of each limit block. A spring is sleeved on the outside of the damper. A printing plate is fixedly connected to the top of the damper. A support assembly is provided on the top of the base plate. As a further description of the above technical solution: The support assembly includes two support frames, the bottoms of the two support frames slide inside the base plate, an inner rod is slidably connected inside the support frame, a screw is threaded inside the support frame, multiple threaded holes are opened inside the inner rod, and a connecting plate is slidably connected inside the inner rod; As a further description of the above technical solution: One end of the spring is fixedly connected to the bottom of the printing plate, and the other end of the spring is fixedly connected to the top of the limiting block; As a further description of the above technical solution: The bottom of the limiting block contacts the top of the support plate, and multiple threaded posts are arranged in an array inside the support plate; As a further description of the above technical solution: A motor is fixedly connected to the top of the connecting plate, and a spray head is slidably connected inside the connecting plate; As a further description of the above technical solution: The outer side of the inner rod slides inside the support frame, and the outer thread of the screw is connected to the inside of the threaded hole; As a further description of the above technical solution: The bottom of the support plate is in contact with the top of the sliding block, and a connecting wire is fixedly connected to the outside of the motor; As a further description of the above technical solution: The base plate is externally fixedly connected to multiple buttons, and the base plate is externally fixedly connected to a control panel.

[0007] This utility model has the following beneficial effects: 1. In this utility model, by rotating the rotating handle, the threaded column pushes the limiting block, which in turn drives the damper to push one side of the printing plate. By rotating the four rotating handles, the tilt of the printing plate can be adjusted. During the printing process, the vibration of the printing plate is absorbed by the spring and the damper, thereby achieving the effect of vibration compensation.

[0008] 2. In this utility model, for printed objects of different heights, the screw is first turned to release the restriction on the inner rod, allowing the inner rod to slide. After the inner rod is stretched to a suitable height, the screw is turned again to allow it to enter different threaded holes, thereby locking it again. Attached Figure Description

[0011] 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.

[0012] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a vibration-compensated 3D printing platform leveling mechanism, comprising a base plate 1. Two sliding grooves 2 are fixedly connected to the top of the base plate 1, limiting the sliding range of sliding blocks 5. Two sliding blocks 5 are slidably connected inside each of the two sliding grooves 2, driving a support plate 4 to slide within the grooves 2. The support plate 4 is fixedly connected to the top of each sliding block 5, supporting the printing plate 3. Multiple threaded posts 6 are threadedly connected inside the support plate 4, rotating within it to allow for upward and downward movement. Rotating handles 7 are fixedly connected to the bottom of each threaded post 6, facilitating rotation of the post 6 by the operator. Limit blocks 8 are rotatably connected to the top of each threaded post 6. The function of the limiting block 8 is to limit the position of the spring 10. The top of the limiting block 8 is fixedly connected to the damper 9, which absorbs the energy of vibration, so that the printing plate 3 can be stable. The spring 10 is sleeved on the outside of the damper 9. The function of the spring 10 is to compress the limiting block 8 and the printing plate 3 directly. The top of the damper 9 is fixedly connected to the printing plate 3. The top of the base plate 1 is provided with a support assembly. One end of the spring 10 is fixedly connected to the bottom of the printing plate 3, and the other end of the spring 10 is fixedly connected to the top of the limiting block 8. The bottom of the limiting block 8 is in contact with the top of the support plate 4. Multiple threaded posts 6 are arranged in an array inside the support plate 4. Multiple buttons 19 are fixedly connected to the outside of the base plate 1. A control panel 20 is fixedly connected to the outside of the base plate 1. The function of the buttons 19 and the control panel 20 is to facilitate printing operation.

[0013] Reference Figure 1 , Figure 4 and Figure 5 The support assembly includes two support frames 11, the bottoms of which slide inside the base plate 1. An inner rod 12 is slidably connected inside each support frame 11. The inner rod 12 provides an extension track when the height of the support frame 11 is insufficient. A screw 17 is threaded inside each support frame 11. The screw 17 rotates inside the inner rod 12, thereby restricting and releasing the restriction on the inner rod 12. Multiple threaded holes 16 are formed inside the inner rod 12, allowing the screw 17 to be rotated into different threaded holes. An internal sliding connection is provided with a connecting plate 13, and a motor 14 is fixedly connected to the top of the connecting plate 13. The motor 14 serves as the driving source for the nozzle 15. The nozzle 15 is slidably connected inside the connecting plate 13 and is used to print on the surface of the printing plate 3. The outer side of the inner rod 12 slides inside the support frame 11. The outer thread of the screw 17 is connected to the inside of the threaded hole 16. The bottom of the support plate 4 contacts the top of the sliding block 5. A connecting wire 18 is fixedly connected to the outside of the motor 14 and is used to connect the motor 14 and the nozzle 15.

[0014] Working principle: Before use, calibration is performed to check whether the printing plate 3 is flat. The operator rotates the rotating handle 7, which rotates inside the threaded column 6, causing the entire threaded column 6 to rotate upward. As the threaded column 6 rotates upward, it pushes the limit block 8 to move upward in sync, and at the same time, it drives the entire damper 9 to move upward, thus moving against one corner of the printing plate 3. By rotating different rotating handles 7, the printing plate 3 can eventually be made flat. At this time, the operation button 19 and control panel 20 start printing. After the nozzle 15 contacts the printing plate 3 and printing begins, the printing plate 3 will vibrate due to the friction of the nozzle 15. At this time, the spring 10 and damper 9 at the bottom of the printing plate 3 will absorb the vibration energy, thus keeping the printing plate 3 stable.

[0015] During use, for objects with different height requirements, the operator uses a tool to rotate the screw 17 so that the screw 17 can be turned out of the threaded hole 16 inside the inner rod 12, thereby releasing the restriction on the inner rod 12. At this time, the inner rod 12 is pulled so that the inner rod 12 slides inside the support frame 11. When the two inner rods 12 slide to the required length, the screw 17 is rotated again so that the screw 17 turns into the different threaded holes 16 opened on the inner rod 12, thereby restricting the inner rod 12 again. At this time, the nozzle 15 can start printing.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
