Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a leveling mechanism for a 3D printer. Background Technology

[0002] 3D printers are machines that use rapid prototyping technology to create three-dimensional objects based on digital model files and using filaments such as wax, ABS, PC, PLA, and nylon. The basic working principle is to heat and melt the filament-like thermoplastic material, and then, under the control of a computer program, the 3D nozzle applies the material to the worktable according to the cross-sectional contour information. After rapid cooling, a cross-section is formed. Then, the worktable is lowered relative to the 3D nozzle to form the next layer, until the entire solid shape is formed. The printing material is stacked layer by layer on the worktable, and its surface needs to be kept flat. Otherwise, the material will be stacked crookedly, resulting in failure of the molding process.

[0003] However, the current leveling method is cumbersome to operate, inconvenient to level directly, and cannot accurately adjust from multiple positions, resulting in insufficient horizontal accuracy of the operating table and affecting the normal printing process. Therefore, this utility model provides a 3D printer leveling mechanism to meet people's needs. Utility Model Content

[0016] 1. Equipped with a convenient leveling mechanism, the adjusting screw is rotated using the adjusting block to adjust the height of the rotating block, thereby changing the position of the connecting block and adjusting the operation panel to a horizontal position. This prevents the operation panel from being tilted, which would cause the material to not be properly stacked during subsequent printing and spraying.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1-4 As shown, this utility model provides a technical solution, a 3D printer leveling mechanism, including a base 1, an operation panel 2 installed above the base 1, and a convenient leveling mechanism 3 installed on the top of the base 1.

[0030] The convenient leveling mechanism 3 includes a threaded hole 301, an adjusting stud 302, an adjusting block 303, a rotating block 304, a connecting block 305, a rotating seat 306, and a limiting frame 307;

[0031] Threaded holes 301 are provided at each of the four corners of the top of the base 1. Adjusting studs 302 are installed at each of the four corners of the top of the base 1. The positions of the adjusting studs 302 and the threaded holes 301 correspond to each other. The bottom of the adjusting stud 302 is embedded in the interior of the threaded hole 301. The adjusting stud 302 and the base 1 are connected by threads. An adjusting block 303 is fixedly connected to the top of the adjusting stud 302. A rotating block 304 is fixedly connected to the middle of the top of the adjusting block 303. Connecting blocks 305 are fixedly connected to each of the four corners of the bottom of the operation panel 2. A rotating seat 306 is rotatably connected to the bottom of the connecting block 305. A positioning shaft is fixedly installed in the middle of the rotating seat 306. The connecting block 305 and the positioning shaft are rotatably connected. The bottom of the rotating seat 306 is fixedly connected to... A limiting circular frame 307 is connected to the control panel 2. A circular slot is provided in the middle of the limiting circular frame 307. A rotating block 304 is rotated and engaged inside the circular slot. The limiting circular frame 307 and the rotating block 304 are movably connected. The adjusting screw 302 is rotated and adjusted by adjusting the adjusting block 303, thereby adjusting the height of the rotating block 304. This causes the position of the connecting block 305 to change accordingly, adjusting the control panel 2 to a horizontal state. This prevents the control panel 2 from tilting, which would cause the subsequent printing and spraying materials to not be properly stacked. All four corners can be adjusted. The adjustment operation is simple and the adjustment is more precise. During leveling and printing, the adjusting screw 302 plays a supporting and stable role. Its bottom is embedded in the interior of the base 1, making the connection between the control panel 2 and the base 1 stronger.

[0032] An auxiliary leveling mechanism 4 is provided on the edge of the operation panel 2;

[0033] The auxiliary leveling mechanism 4 includes a notch 401, a pipe level 402, a limiting insertion hole 403, a sealing block 404, a positioning rod 405, and a sealing plate 406;

[0034] The control panel 2 has notches 401 in the middle of its sides, and a tubular level 402 is fixedly installed in the middle of the notch 401. Limiting holes 403 are provided on both sides of the tubular level 402 inside the notch 401. A sealing block 404 is embedded in one end of the notch 401. Positioning rods 405 are symmetrically fixed to both ends of the sealing block 404. A sealing plate 406 is fixedly connected to the top of the sealing block 404. The positioning rods 405 are movably inserted into the limiting holes 403. The side of the sealing block 404 is flush with the edge of the control panel 2, and the sealing plate 406 is flush with the top of the control panel 2. The tubular level 402 can be used to adjust the leveling process. Monitoring allows staff to determine whether the operation panel 2 is level using the tube level 402. The operation is simple, and since it is fixed to the operation panel 2, no additional leveling equipment is needed, making it more convenient to use. The positioning rod 405 and the limiting hole 403 work together to fix the sealing block 404 and the sealing plate 406 at the notch 401, covering and sealing the notch 401, thus providing flat protection. This ensures that the edges and surface of the operation panel 2 remain flat, greatly facilitating printing and product unloading, preventing printing materials or products from slipping and scratching, and also covering and protecting the tube level 402 from damage caused by prolonged exposure.

[0035] The working principle and usage process of this utility model are as follows: First, the staff pulls out the sealing block 404 and the sealing plate 406, so that the positioning rod 405 is disengaged from the inside of the limiting insertion hole 403, and the pipe level 402 is exposed. The staff can use the four pipe levels 402 on the side of the operation panel 2 to determine which direction the operation panel 2 is tilted.

[0036] Then, the staff selects the corresponding corner and rotates the adjusting stud 302 by holding the adjusting block 303. This causes the bottom of the adjusting stud 302 to descend into the threaded hole 301 or rise out of the threaded hole 301, thereby adjusting the height of the rotating block 304. The rotating block 304 rotates and rises or falls together with the adjusting stud 302. It rotates inside the limiting frame 307, causing the rotating seat 306 and the connecting block 305 to rise or fall together. This adjusts the height of the corresponding corner of the operating panel 2. The adjustment is made multiple times according to the tube level 402 until the operating panel 2 is level.

[0037] Next, the staff took the sealing block 404 and the sealing plate 406 and embedded them into the notch 401. The positioning rod 405 was aligned with the limiting hole 403 and inserted into it, so that the sealing block 404 was embedded in the middle of the notch 401 and flush with the edge of the operation panel 2. The sealing plate 406 covered the top of the notch 401, and its top was flush with the top of the operation panel 2, so that the surface of the operation panel 2 remained flat, making printing operation more convenient. At the same time, it covered and protected the tube level 402, preventing it from being easily damaged by direct exposure for a long time.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
