The carbonization furnace body 3 is internally divided into a first carbonization chamber 301 and a second carbonization chamber 302. Multiple exhaust pipes 4 are connected to the carbonization furnace body 3, and electric valves 5 are installed on the exhaust pipes 4. A first hollow graphite heating element 6 is installed on the first carbonization chamber 301 for preheating the negative electrode material. A second hollow graphite heating element 6 is installed on the second carbonization chamber 302. Hollow graphite heating element 7, the second hollow graphite heating element 7 is used to carbonize the negative electrode material. A first fixed frame 8 is fixedly connected to the reinforcing plate 1. A first electric push rod 9 is fixedly installed on the first fixed frame 8. A first connecting rod 10 is connected to the telescopic rod of the first electric push rod 9. The first connecting rod 10 is slidably connected to the carbonization furnace body 3. A feeding rack 11 is connected to the first connecting rod 10. A fixed sliding rod 13 is fixedly connected to the carbonization furnace body 3. Two second fixed frames 14 are fixedly connected to the carbonization furnace body 3. The second fixed frames 14 are fixedly installed with... A second electric push rod 15 is provided, with a second connecting rod 16 connected to the top of the telescopic rod of the second electric push rod 15. A sliding frame 17 is fixedly connected to the second connecting rod 16, and the sliding frame 17 is slidably connected to the fixed sliding rod 13. A sealing door 18 is connected between the two sliding frames 17, and the sealing door 18 is used to control the opening and closing of the carbonization furnace body 3 channel. A transport frame 19 is fixedly connected to the reinforcing plate 1, and a third fixed frame 20 is fixedly connected to the transport frame 19. A drive motor 21 is fixedly installed on the third fixed frame 20, and a rotating connection is made on the transport frame 19. A lead screw 22 is connected to the output shaft of a drive motor 21. A distance sensor 23 is installed on the transport frame 19. A movable block 24 is slidably connected to the transport frame 19. The movable block 24 is threadedly connected to the lead screw 22. A third electric push rod 25 is fixedly installed on the movable block 24. A third connecting rod 26 is connected to the bottom of the telescopic rod of the third electric push rod 25. A double-rod cylinder 27 is fixedly installed on the third connecting rod 26. A fourth connecting rod 28 is connected to the telescopic rod of the double-rod cylinder 27. A clamping block 29 is connected to the fourth connecting rod 28.
[0020] The controller 2 is equipped with a transport button.
[0021] A material container 12 is placed on the feeding rack 11.
[0022] The first connecting rod 10 is made of heat-insulating material.
[0023] The working principle of this utility model is as follows: the distance sensor is equipped with a first threshold and a second threshold, and the value of the first threshold is smaller than the value of the second threshold.
[0024] After the negative electrode material is placed into the holding cylinder, the first electric push rod is controlled to move the first connecting rod, the feeding rack, and the holding cylinder, so that the holding cylinder moves into the first carbonization chamber. Then, the second electric push rod is controlled to move the second connecting rod, the sliding frame, and the sealing door down, so that the sealing door closes the carbonization furnace body channel. Subsequently, the first hollow graphite heating element and the second hollow graphite heating element are energized, so that the first hollow graphite heating element preheats the negative electrode material. After the negative electrode material is preheated, the first electric push rod is controlled to move the first connecting rod, the feeding rack, and the holding cylinder into the second carbonization chamber. The heat generated by the second hollow graphite heating element carbonizes the negative electrode material.
[0025] After the negative electrode material is carbonized, the first and second hollow graphite heating elements are stopped. Then, the electric valve opens the exhaust pipe channel to allow hot gas to escape. Next, the second electric push rod moves the second connecting rod, sliding frame, and sealing door to their reset positions, opening the carbonization furnace passage. The first electric push rod then moves the first connecting rod, feeding frame, and material cylinder in the opposite direction, positioning the material cylinder directly below the clamping block. The third electric push rod moves the third connecting rod, double-rod cylinder, fourth connecting rod, and clamping block to a designated height, positioning the material cylinder between the two clamping blocks. The double-rod cylinder then moves the fourth connecting rod and clamping block inwards, clamping the material cylinder. After clamping, the third electric push rod moves the third connecting rod, double-rod cylinder, fourth connecting rod, and clamping block back to their reset positions. Finally, the transport button is pressed, controlling the drive motor to rotate the lead screw. The lead screw then moves the moving block, the third electric push rod, and the third... The connecting rod, double-rod cylinder, fourth connecting rod, and clamping block move. When the distance between the moving block and the distance sensor reaches the first preset threshold of the distance sensor, the drive motor stops working. At the same time, the third electric push rod drives the third connecting rod, double-rod cylinder, fourth connecting rod, and clamping block to descend to a specified height. Then, with the help of a tool to catch the material cylinder, the double-rod cylinder drives the fourth connecting rod and clamping block to move outward, causing the clamping block to release the material cylinder. Next, the material cylinder containing the uncarbonized negative electrode material is placed between the two clamping blocks. After the clamping blocks clamp, the transport button is pressed again, thereby controlling the drive motor to drive the lead screw to rotate in the opposite direction. The lead screw drives the moving block, third electric push rod, third connecting rod, double-rod cylinder, fourth connecting rod, and clamping block to move in the opposite direction. When the distance between the moving block and the distance sensor reaches the second preset threshold of the distance sensor, the drive motor stops working. At the same time, the clamping block releases the material cylinder, allowing the material cylinder to fall smoothly onto the feeding rack.

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.
