[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1 and Figure 2 As shown, the automatic pouring machine includes an automatic control system and a ladle 5 for containing molten steel.

[0023] The automatic control system includes a touch screen 1, a PLC system 2 and a servo motor 3. The touch screen 1 is used to input instructions, the PLC system 2 is used to transmit instructions to the servo motor 3, and the servo motor 3 executes the instructions.

[0024] Furthermore, both the touch screen 1 and the PLC system 2 are placed parallel to the operating table 8, and in order to ensure the safety of the operating workers and better observe the specific conditions of the molten steel stored in the ladle 5, a certain distance is set between the operating table 8 and the ladle 5 and the operating table 8 itself has a certain height.

[0025] The servo motors 3 are fixedly mounted on the outer wall of the robot arm 6 , and two servo motors 3 are arranged in parallel, with a gap between the two servo motors 3 .

[0026] The robotic arm 6 is provided with an electronic scale 61 and a connecting rod 62 . The electronic scale 61 can accurately calculate the weight of the molten steel. The connecting rod 62 is used to connect the stopper rod 4 .

[0027] The robot arm 6 is located in the interval between the two servo motors 3 and has a lifting slot for lifting.

[0028] One end of the servo motor 3 at the upper end is connected to the lifting switch 63 of the control connecting rod 62. The lifting switch 63 includes two cooperating gears, a lifting limit rod, a lifting handle and a connecting piece.

[0029] Furthermore, the connecting rod 62 is connected to the stopper rod 4 , and the stopper rod 4 is lifted or lowered to press against or release the pouring outlet 51 inside the ladle 5 .

[0030] The pouring water outlet 51 is located at the bottom center of the ladle 5 .

[0031] When the touch screen 1 issues a lifting command, the PLC system 2 transmits the command to the servo motor 3. After the servo motor 3 receives the command, the robot arm 6 starts to run and drives the lifting switch 63. At this time, the connecting rod 62 drives the stopper rod 4 to rise or fall.

[0032] Furthermore, a bearing rod 7 is provided on the left side of the robotic arm 6 , and the bearing rod 7 is connected to a ladle cover 71 and a rotary switch 72 .

[0033] The ladle cover 71 has good sealing performance and is suitable for various types of ladles 5 . The rotary switch 72 is connected to one side of the two servo motors 3 .

[0034] The bearing rod 7 is also provided with a bearing adapted for rotation function.

[0035] When the touch screen 1 issues a rotation instruction, the PLC system 2 transmits the instruction to the servo motor 3. After the servo motor 3 receives the instruction, the robotic arm 6 starts to run and drives the rotation switch 72. At this moment, the bearing rod 7 rotates left or right.

[0036] Furthermore, support frames 52 are provided on both sides of the lower exterior of the ladle 5 . Through this arrangement, the interior of the ladle 5 has a certain heat preservation function.

[0037] A lifting column 53 for supporting a crane for tower crane is provided on the left side of the ladle 5 .

[0038] The utility model realizes accurate control of the pouring process and quality stability of the castings through the automatic control system and electronic weighing equipment, and has a fixed rotation function, reduces the safety hazards caused by improper manual operation and the labor intensity of the operators, and improves the working environment.
