[0027] According to the overall structure of the device, the mounting base 5 is correctly installed on the 3D printer. After the installation is completed, the same volume of water is input into each transparent tube 11 to make the floating block 12 float, so that the infrared sensor 14 and the infrared transmitter 13 remain horizontal. Due to the arrangement of the U-shaped seat 7, the bearing 9 and the mounting shaft 8, the transparent tube 11 on the sleeve frame 10 is quickly changed in angle by gravity through the counterweight block 15. At this time, if the supporting platform 1 is not in a horizontal state, the values ​​of each micro height sensor 16 are different. The PLC controller 6 drives each electric push rod 3 to make corrections, and the one close to the low value is The electric push rod 3 of the micro height sensor 16 rises, and the electric push rod 3 of the micro height sensor 16 with a higher value falls. When it is adjusted to the point where the infrared sensor 14 can continuously receive the infrared rays emitted by the infrared transmitter 13, the PLC controller 6 drives the electric push rod 3 to stop, thereby completing the leveling. When performing 3D printing, the positioning column 18 on the bottom surface of the platform plate 19 is inserted into the positioning cylinder 17, and the positioning column 18 is fixed by adsorbing the magnetic block 20, and then printing is performed.

The transparent tube 11 is an infrared transmission material tube. Both ends of the inner wall of the transparent tube 11 are provided with limiting grooves. Both ends of the floating block 12 are fixedly connected to the limiting strips. The floating block 12 is placed on the inner wall of the transparent tube 11, and the limiting strips are inserted into the limiting grooves. The arc surface of the transparent tube 11 is provided with an auxiliary component, and the top surface of the floating block 12 is provided with a detection component.

[0029] By setting the U-shaped seat 7, the mounting shaft 8, the bearing 9, the sleeve 10, the transparent tube 11 and the floating block 12, when the supporting platform 1 is not kept horizontal and the transparent tube 11 on the sleeve 10 is tilted, the angle is changed by the U-shaped seat 7, the mounting shaft 8 and the bearing 9.

[0030] like Figure 3-4 As shown, the detection component includes an infrared transmitter 13 and an infrared sensor 14. The infrared transmitter 13 is fixedly installed on the top surface of two of the floating blocks 12, and the infrared sensor 14 is fixedly installed on the top surface of the other two floating blocks 12. The transmitting port of the infrared transmitter 13 and the receiving port of the infrared sensor 14 are kept opposite to each other.

[0031] Through the infrared emitter 13 and the infrared sensor 14 , when the angles of the transparent tube 11 and the ground are the same, the infrared rays emitted by the infrared emitter 13 can be received by the infrared sensor 14 .

[0032] like Figure 1 As shown, the detection component also includes a counterweight 15 and a micro height sensor 16 . The counterweight 15 is fixedly mounted on the lower end of the arc surface of the transparent tube 11 , and the micro height sensor 16 is fixedly mounted on the bottom surface of the counterweight 15 .

[0033] By providing the counterweight 15 and the micro height sensor 16 , the counterweight 15 can speed up the speed at which the transparent tube 11 changes its angle, and the micro height sensor 16 can record the current height data.

[0034] like Figure 5-6As shown, the detachable components include a platform plate 19, a positioning cylinder 17 and a positioning column 18. The four ends of the top surface of the support platform 1 are fixedly installed with the positioning cylinders 17, and the four ends of the bottom surface of the platform plate 19 are respectively fixedly installed with the positioning columns 18.

[0035] By setting the platform plate 19, positioning cylinder 17, positioning column 18 and magnetic block 20, when performing 3D printing, the positioning column 18 on the bottom surface of the platform plate 19 is inserted into the positioning cylinder 17, and the positioning column 18 is fixed by adsorbing it through the magnetic block 20, and then printing is performed. After printing is completed, the platform plate 19 can be removed from the supporting platform 1, which is convenient for unloading the printed model.

[0036] Working principle: Install the mounting base 5 correctly on the 3D printer. After installation, input the same volume of water into each transparent tube 11 to make the floating block 12 float, so that the infrared sensor 14 and the infrared transmitter 13 remain horizontal. Due to the arrangement of the U-shaped seat 7, the bearing 9 and the mounting shaft 8, the transparent tube 11 on the sleeve 10 is quickly changed in angle by gravity through the counterweight 15. At this time, if the supporting platform 1 is not in a horizontal state, the values ​​of each micro height sensor 16 are different. The PLC controller 6 drives each electric push rod 3 to make corrections. The electric push rod 3 near the micro height sensor 16 with a low value rises, and the electric push rod 3 near the micro height sensor 16 with a high value falls. When it is adjusted to the point where the infrared sensor 14 can continuously receive the infrared rays emitted by the infrared transmitter 13, the PLC controller 6 drives the electric push rod 3 to stop, thereby completing the leveling. When performing 3D printing, the positioning column 18 on the bottom surface of the platform plate 19 is inserted into the positioning cylinder 17, and the positioning column 18 is fixed by adsorbing the magnetic block 20, and then printing is performed. After printing is completed, the platform plate 19 can be removed from the supporting platform 1.
