[0023] Through the cooperation of the niobium-based alloy seat 13 and the conductive shaft 25, the device can conduct electricity through the conductive shaft 25 made of niobium-based alloy and the niobium-based alloy seat 13 when running at high speed, thereby making the conductivity of the equipment more stable during high-speed operation and avoiding intermittent conduction. At the same time, the wear-resistant property of the niobium-based alloy can avoid serious wear of the conductive shaft 25 and the niobium-based alloy seat 13 after long-term use, thereby reducing the maintenance cost of the equipment.

[0024] An extrusion spring 23 is movably installed between the sliding shaft 24 and the inside of the sliding groove 22 . A wiring terminal 27 is connected to the outer surface of the conductive shaft 25 . A diaphragm gasket 14 is provided on the top of the niobium-based alloy seat 13 .

[0025] By cooperating with the extrusion spring 23 and the sliding shaft 24, the sliding shaft 24 is subjected to the elastic potential energy of the extrusion spring 23 to drive the conductive shaft 25 to move toward the niobium-based alloy seat 13, thereby making the conductive shaft 25 close to the surface of the niobium-based alloy seat 13, thereby avoiding the situation where a gap is generated between the conductive shaft 25 and the niobium-based alloy seat 13 due to the shaking of the device, and enabling the device to be installed and used with main shafts 3 and niobium-based alloy seats 13 of different sizes.

[0026] A lifting groove 15 is provided on the bottom surface of the movable seat 11, and the top end of the lifting rod 17 is slidably inserted into the lifting groove 15.

[0027] Through the cooperation between the lifting rod 17 and the limiting buckle 20, when the device is in use, the limiting buckle 20 can be pressed inward to retract the limiting buckle 20 into the spring groove 18. At this time, the lifting rod 17 can be lifted and lowered inside the lifting groove 15, so that the lifting rod 17 drives the fixing rod 21 to move up and down. When the fixing rod 21 moves to a specified height position, the limiting buckle 20 is released. The limiting buckle 20 will be ejected outward by the elastic potential energy of the compression spring 19 and stuck in another limiting hole 16, thereby limiting the lifting rod 17. Therefore, the device can conveniently adjust the fixing rod 21 according to the installation height position of the niobium-based alloy seat 13, and then conveniently adjust the height position of the conductive shaft 25 and the niobium-based alloy bearing 26, so as to facilitate the use of the device.

[0030] A connection terminal 27 is provided inside the bottom end of the niobium-based alloy seat 13 .

[0031] When the sliding contact conductive mechanism is in use, the motor can cooperate with the connection between the drive belt and the drive pulley 8 to drive the drive pulley 8 to rotate, thereby driving the main shaft 3 and the rotating barrel 2 to rotate. When the device is running at high speed, the conductive shaft 25 and the niobium-based alloy seat 13 made of niobium-based alloy can be used for conductive conduction, thereby making the conductive conduction of the equipment more stable during high-speed operation, avoiding the occurrence of intermittent conductive conduction. At the same time, the wear-resistant property of the niobium-based alloy can avoid the conductive shaft 25 and the niobium-based alloy seat 13 from being severely worn after long-term use, thereby reducing the maintenance cost of the equipment.

[0032] Through the cooperation of the extrusion spring 23 and the sliding shaft 24, the sliding shaft 24 is subjected to the elastic potential energy of the extrusion spring 23 to drive the conductive shaft 25 to move in the direction of the niobium-based alloy seat 13, so that the conductive shaft 25 is closely attached to the surface of the niobium-based alloy seat 13, avoiding the situation that a gap is generated between the conductive shaft 25 and the niobium-based alloy seat 13 due to the shaking of the device, and the device can be installed and used with the main shaft 3 and the niobium-based alloy seat 13 of different sizes.
