This precise control helps to reduce transportation time and improve operating efficiency.
[0040] See also Figures 1 to 4In one embodiment of the present invention, the suction module platform 13 is formed with a first suction area 132, a second suction area 133 and a third suction area 134 which are respectively connected to the first material area 250, the second material area 260 and the third material area 270.

The second material zone 260 is a fixed location, and each fixed location is spaced apart. Therefore, the three-way pipe is designed to accommodate the location of the second material zone 260. The three-way pipe can simultaneously absorb resistor material from two fixed locations, thereby improving suction efficiency. The resistor material in the first material zone 250 and the second material zone 260 has a relatively large depth. The retractable suction cylinder 131 can be adjusted according to the depth of the material zone. Regardless of the depth of the material zone, the suction operation can be effectively performed, and the adjustment can be made quickly and accurately to accommodate material zones of varying depths, thereby improving suction efficiency and the overall production capacity of the production line.

[0044] See also Figures 1 to 6 In one embodiment of the present invention, the automated material suction and screening system 100 for auxiliary materials used in the production of artificial graphite negative electrode materials includes three vibrating screening devices 6 and three material storage bins 7. Each vibrating screening device 6 includes a screen 61, a screening port 62, and a screening discharge pipe 63. Each screen 61 is located below the discharge end of a material storage bin 7, and each screening port 62 is located at the end of a screen 61. The two ends of each screening discharge pipe 63 are respectively connected to a screening port 62 and a material storage bin 7. Each screen 61 is designed with a different aperture size to accommodate resistor materials of different particle sizes. The screening material can filter out impurities, foreign matter, or oversized particles in the resistor materials of different particle sizes, ensuring that the resistor materials entering the material storage bin 7 are clean and pure. The screening material can also homogenize the particle size of the resistor materials, avoiding the problem of uneven particle size in the material storage bin 7 and ensuring stability and consistency in the subsequent production process.
[0045] See also Figure 5 and Figure 6 In one embodiment of the present invention, the automated suction and screening system 100 for auxiliary materials used in the production of artificial graphite negative electrode materials includes a support platform 8, the discharge ends of the three material storage bins 7 are spaced apart on the support platform 8, and each of the vibration screening devices 6 is located below the support platform 8, corresponding to the discharge end of one of the material storage bins 7. Each vibration screening device 6 corresponds to the discharge end of one of the material storage bins 7 and is located below the support platform 8. This layout allows operators to easily access and maintain each vibration screening device 6 without interference from other components or spatial restrictions. The vibration screening device 6 is located below the support platform 8, which can more effectively screen out the required material particle size and ensure the quality and uniformity of the resistor material entering the material storage bin 7. This direct vertical layout helps reduce the problem of stratification or mixing of materials during transportation and improves screening efficiency. The arrangement between the discharge end of each material storage bin 7 and the vibration screening device 6 makes the assembly and adjustment process simpler, reduces the process complexity and time consumption during the assembly process, and improves the reliability and stability of the equipment.
[0046] See also Figure 5 and Figure 6 In one embodiment of the present invention, the screen 61 is tilted, and the screening opening 62 is located at the tilted end of the screen 61. The tilted setting can use gravity to help the resistor material move quickly and be layered on the screen 61, thereby increasing screening efficiency. The resistor material moves from top to bottom along the tilted surface of the screen 61, effectively accelerating the screening process. The screening opening 62 is located at the tilted end of the screen 61, which can more easily prevent the resistor material from staying or adhering to the screen 61, reducing the possibility of clogging the screen holes and maintaining the continuity and stability of the screening. The tilted setting of the screen 61 can make it easier to separate resistor materials of different particle sizes, with large particles sliding downward and small particles falling through the screen holes, thereby achieving effective grading and screening. The location of the screening opening 62 makes cleaning and maintenance of the screen 61 more convenient, and operators can more easily access and handle impurities or clogging materials on the screen 61, thereby maintaining the normal operation of the equipment.
[0047] See also Figure 1In one embodiment of the present invention, the automatic material suction and screening system 100 for auxiliary materials used in the production of artificial graphite negative electrode materials includes three third connecting valves 9, and the two ends of each of the third connecting valves 9 are respectively connected to a screening material pipeline 63 and a material storage bin 7. The third connecting valve 9 allows the operator to control the flow of materials from the screened material pipeline 63 to the material storage bin 7. By opening or closing the third connecting valve 9, the flow direction and flow rate of the material can be precisely controlled to ensure the stability and controllability of the material supply during the production process; the presence of the third connecting valve 9 allows the operator to adjust and maintain the equipment more conveniently. If the screen 61 or the screen port 62 needs to be cleaned or replaced, the material flow can be cut off by closing the corresponding third connecting valve 9 to avoid unnecessary loss or leakage of materials during operation; the third connecting valve 9 can serve as an important safety valve. When the equipment fails or requires emergency shutdown, the third connecting valve 9 can be closed to prevent the material from continuing to flow, reducing the possibility of accidents and losses; in the daily maintenance and cleaning of the equipment, the presence of the third connecting valve 9 can simplify the cleaning and inspection steps. By closing the third connecting valve 9, the material flow between different components can be effectively isolated and managed to ensure the efficiency and safety of maintenance work.
