Example 3

[0027] The present invention also discloses a large-size cathode roller hot-loading process, the steps of which are as follows: Step 1: The inner wall of the cathode roller 102 is limited by the transmission unit 200 so that the cathode roller 102 can be clamped; Step 2: Clamp the transmission unit 200 by the existing clamping device, and then install it by the existing lifting device and clamping device, so that the clamped cathode roller 102 can be lifted, and the cathode roller 102 can be placed in the heating furnace 101 by controlling the lifting device; Step 3: The cathode roller 102 can be initially straightened by the conical discharge hopper 103 and the discharge pipe 1031 in the inner cavity of the heating furnace 101, and the cathode roller 102 continues to be suspended, so that the cathode roller 102 can press the first flip plate 301 and the second flip plate 3011 to flip, so that the first flip plate 301 and the second flip plate 3011 cooperate with the positioning unit 300, so that the cathode roller 102 can be positioned by the first positioning plate 3035 and the second positioning plate 3036, so that the distance between the cathode roller 102 and the heating furnace 101 is evenly distributed; Step 4: At this time, the clamping device is released, so that the cathode roller 102 is located in the heating furnace 101, and the feed port 1012 of the heating furnace 101 is closed, and heating and protective gas are filled until the heating is completed; Step 5: At this time, the heating furnace 101 is opened and the clamping operation of the above step 2 is completed by the clamping device, so that the cathode roller 102 can be taken out.

[0028] The implementation principle of a large-size cathode roller hot-loading device of the present invention is as follows: First, the staff places the transmission unit 200 in the middle of the inner wall of the cathode roller 102. When the placement is completed, the staff rotates the self-locking rotating knob 202, so that the self-locking rotating knob 202 can drive the rotating rod 2021 to rotate. When the rotating rod 2021 rotates, it can drive the first bevel gear 2022 to rotate. When the first bevel gear 2022 rotates, it can drive the second bevel gear 2023 to rotate, so that the threaded rod 203 can be driven to rotate through the second bevel gear 2023; When the threaded rod 203 rotates, the threaded sleeve 2031 can be driven to move horizontally with the assistance of the guide rod 2032. When the threaded sleeve 2031 moves horizontally, the limit plate 2033 can be driven to move through the driving rod 2038, so that the limit plate 2033 can be pressed against the inner wall of the cathode roller 102 (a protective pad is provided on one side of the limit plate 2033 close to the inner wall of the cathode roller 102); At the same time, when the threaded sleeve 2031 moves horizontally, it can also drive the connecting plate 2035 to move horizontally, and the connecting plate 2035 can drive the upper positioning plate 2036 and the lower positioning plate 2037 to move horizontally, so that the side wall of the cathode roller 102 can be limited by the upper positioning plate 2036 and the lower positioning plate 2037, and the cathode roller 102 can be further prevented from falling off during hoisting. When the cathode roller 102 is completely limited, the cathode roller 102 can be lifted by the existing clamping equipment and lifting equipment, and then placed in the heating furnace 101. The conical discharge hopper 103 and the discharge pipe 1031 provided in the heating furnace 101 can play a guiding role, so that the placed cathode roller 102 can be initially located in the middle of the heating furnace 101. When the cathode roller 102 moves downward in the heating furnace 101, it can respectively squeeze the first flip plate 301 and the second flip plate 3011 to rotate with the assistance of the rotating rod 3012. When the first flip plate 301 and the second flip plate 3011 rotate, the plug-in rod 3021 can be lifted up, so that the moving plate 3024 can be pushed vertically upward with the assistance of the slide groove 3022 and the slider 3023 through the plug-in rod 3021. When the movable plate 3024 moves horizontally upward, it will be able to drive the movable rod 303 to move vertically upward. When the movable rod 303 moves vertically upward, it will be able to drive the connecting plate 3031 to move vertically upward. When the connecting plate 3031 moves upward, it can drive the placement plate 3033 to move horizontally with the assistance of the second telescopic rod 3037 through the movable rod 3032, so that the placed cathode roller 102 can be clamped and positioned, thereby ensuring that the cathode roller 102 is located in a uniform state inside the wall of the heating furnace 101, ensuring that it is heated more evenly.
