The telescopic tube 73 is installed at the discharge port of the feeder 21. The feeder 21 is used to feed the powder into the telescopic tube 73. The telescopic tube 73 is used to gather the powder and discharge it into the graphite blank box. The telescopic tube 73 can be used to lower the powder discharge position into the graphite blank box, that is, the telescopic tube 73 reduces the height difference of the dust from the outlet to the graphite blank box, which can reduce the generation of dust. At the same time, the telescopic tube 73 can be folded during the rotation of the feeder 21 without affecting the rotation. The rope collector 71 is installed on the feeder 21, the front end of the traction rope 72 is fixed on the rope collector 71, and the rear end of the traction rope 72 is fixed on the telescopic tube 73.

The slide rail 61 is also provided with a suspension rod 64, the suspension rod 64 is fixed to the silo body 11 of the powder silo 1, the suspension rod 64 is used to increase the bearing capacity of the slide rail 61, and there are multiple suspension rods 64, and the number of suspension rods 64 is set according to demand. The feeder 21 is provided with a pulley 23 frame 22, and the pulley 23 is provided on the pulley 23 frame 22, and the pulley 23 is slidably arranged on the slide rail 61, so that the feeder 21 can slide on the hanger 6. The slide rail 61 is in an arc shape and is provided with two slide grooves 611 . A pulley 23 is provided in each slide groove 611 , so that the pulley 23 will not separate from the slide rail 61 in the radial direction of the slide rail 61 .

The connecting pipe 8 is provided with a negative pressure interface 82, which can be connected to a negative pressure fan through a pipeline, and after the filling is completed, the dust in the air is sucked, the dust in the working environment is reduced, and the occurrence of occupational diseases is reduced.

[0033] When in use, the slide of the rope collector 71 moves toward one end of the telescopic tube 73, releasing the rear end of the traction rope 72, thereby expanding the telescopic tube 73, and the powder is discharged from the powder bin 1 into the rotary joint 3, and then falls into the feeder 21. The feeder 21 discharges the powder into the telescopic tube 73, and the graphite blank box falls from the telescopic tube 73. During the filling process, the slide of the rope collector 71 moves slowly or intermittently toward one end of the powder bin 1, driving the rear end of the traction rope 72 to pull up, gradually or stepwise folding the telescopic tube 73, until the graphite blank box is filled, at which time the telescopic tube 73 is just folded, and then the negative pressure fan connected to the negative pressure interface 82 extracts the generated dust. After completion, the transmission shaft 42 of the rotary driver 41 rotates a certain angle, and the transmission shaft 42 drives the feeder 21 to rotate a certain angle, so that the telescopic tube 73 rotates to the top of the adjacent graphite blank box. The filled graphite blank box can be lifted away by the gantry car, and the other graphite blank box can be filled without affecting each other, thereby improving the filling efficiency.
