[0003] ZL2020223709649 discloses a conductive block for a foil machine. The motion friction mode between the conductive ring and the tungsten-copper alloy plate is sliding friction. After long-term operation, the conductive ring and the tungsten-copper alloy plate generate severe heat and friction, which affects the conductive effect. At the same time, sliding friction causes large friction loss between the conductive ring and the tungsten-copper alloy plate, which greatly shortens the normal service life. The conductive ring and the tungsten-copper alloy plate need to be replaced regularly, which increases production costs. Technical issues

[0004] In order to overcome the disadvantages of the prior art that the conductive ring and the tungsten-copper alloy plate need to be replaced regularly, thereby increasing production costs, the present invention provides a conductive device for a foil production machine. Technical Solutions

[0007] The connection between the short copper bar and the long copper bar is silver-plated. The bottom of the short copper bar is connected to the negative pole of the power supply, and the long copper bar is fixedly connected to the conductive copper block. The contact area between the long copper bar and the conductive copper block is silver-plated to improve contact conductivity.

[0015] The conductive shoe pole copper block is placed above the conductive copper block, and the bottom of the conductive shoe pole copper block is silver-plated to increase contact conductivity.

[0016] When the alloy sleeve and the conductive ring are working, the friction motion mode is rolling friction motion, which reduces the running resistance and friction loss and can greatly increase the service life of the conductive ring and the alloy sleeve.

[0020] By optimizing the structure of the conductive shoe-pole assembly, an alloy sleeve capable of rotational motion was designed. The movement mode of the conductive shoe-pole assembly and the conductive ring was changed to rolling friction instead of the existing sliding friction mode, which effectively reduced the friction loss between the conductive ring and the conductive shoe-pole assembly during operation. While reducing the friction resistance of the conductive ring during operation, it can greatly increase the service life of the conductive ring and the tungsten-copper shoe-pole assembly, while reducing production costs.

[0029] This embodiment is a conductive device for a foil production machine, comprising a short copper busbar 1, a long copper busbar 2, a conductive copper block 3, a pipe joint 4, a conductive shoe pole assembly 6, a conductive ring 7, a conductive oil tank side plate 8, and a conductive oil tank end plate 9. The conductive oil tank is located on the upper surface of the conductive copper block 3, and two conductive shoe pole assemblies 6 are located within the conductive oil tank, symmetrically positioned on the upper surface of the conductive copper block 3. Mounting holes for the pipe joints 4 are provided at each end of the conductive copper block 3. One end of each pipe joint is threaded into the mounting holes and sealed by a sealing ring 5. Two long copper busbars 2 are located parallel to the lower surface of the conductive copper block 3. Two short copper busbars 1 are located on the lower surface of each long copper busbar, and the side surface of one short side of each short copper busbar is fixedly connected to the lower surface of the long copper busbar by connecting screws 11. The lower half of the conductive ring 7 is located within the conductive oil tank and positioned on the upper surface of each of the two conductive shoe pole assemblies 6.

[0030] The conductive shoe pole assembly 6 is fixed to the conductive copper block 3 by bolts, the conductive oil tank side plate 8 is connected to the conductive copper block by screws, and the conductive oil tank end plate 9 is fixed to the conductive copper block 3 by fixing screws 19. The cavity formed by the conductive oil tank side plate, the conductive oil tank end plate and the conductive copper block is sealed to form a conductive oil tank. During operation, the conductive ring 7 is placed above the two conductive shoe pole assemblies 6, and a certain amount of conductive oil is placed in the conductive oil tank. The conductive oil here mainly serves the functions of lubrication, arc extinguishing and conduction.

[0031] The connection between the short copper busbar 1 and the long copper busbar 2 is silver-plated. The bottom of the short copper busbar 1 is connected to the negative pole of the power supply. The long copper busbar 2 is fixed to the conductive copper block 3 via a connecting bolt 10. The contact area between the long copper busbar 2 and the conductive copper block 3 is silver-plated to improve contact and conductivity.

[0032] The conductive shoe-pole assembly 6 includes a conductive shoe-pole copper block 12, a flat key 13, an alloy sleeve 14, a shaft 15, a bearing 16, a hole retaining ring 17, and a shaft retaining ring 18, as shown in Figures 5 and 6. The conductive shoe-pole copper block 12 is placed above the conductive copper block 3, and the bottom of the conductive shoe-pole copper block 12 is silver-plated to enhance contact conductivity. Bearings 16 are located on either side of the conductive shoe-pole copper block 12, and the ends of the shaft 15 are mounted in these bearings. The alloy sleeve 14 is mounted on the outer circumference of the shaft 15 and secured by the flat key 13. When the shaft 15 rotates, it also drives the alloy sleeve 14 to rotate.

[0033] The conductive shoe copper block 12 is a square block, and the front end of the upper surface of the conductive shoe copper block is processed into a slope. There is a groove with a U-shaped cross-section on the slope. The bottom surface and the two side surfaces of the groove constitute an arc surface that matches the outer circumferential surface of the alloy sleeve 14; the groove is the alloy sleeve mounting groove.

[0034] A hole retaining ring 17 is mounted on the conductive shoe copper block 12 to secure the outer ring of the bearing 16. A shaft retaining ring 18 is mounted on the shaft 15 to secure the inner ring of the bearing 16 to prevent axial movement of the bearing 16. During operation, the alloy sleeve 14 and the conductive ring 7 move relative to each other, changing from the existing sliding friction motion to rolling friction motion. This reduces frictional resistance during operation and significantly increases the service life of the conductive ring 7 and the alloy sleeve 14.

[0035] The conductive copper block 3 is in the shape of a hollow rectangular block, and the long circular space inside the block serves as a cooling cavity to prevent the conductive copper block 3 from affecting its conductive performance due to heat.

[0036] Different from the existing technology, the present invention provides a conductive device for a foil production machine. The movement mode of the conductive shoe pole assembly and the conductive ring adopts rolling friction instead of the existing sliding friction mode, which reduces the friction resistance of the conductive ring and can greatly improve the service life of the conductive ring and the tungsten copper shoe pole assembly, while reducing production costs.
