The electrode sheet formed after hot pressing and laminating is then conveyed to the right by a pressing and conveying mechanism, which is convenient for later processing and manufacturing.

[0051] See also Figure 3When it is necessary to heat press and laminate from left to right during production, the drive motor 13 is started. Under the power output of the drive motor 13, the active pulley 32 is driven to transmit, and then the drive belt 33 is driven to transmit, thereby driving the driven pulley 34, the matching rotating shaft 35 located below, the adjusting bevel gear 43, and the heating roller 16 to rotate synchronously.

[0052] When it is necessary to make electrode sheets of different thicknesses and adjust the spacing between the two heating rollers 16, the adjusting block 6 is rotated to drive the adjusting screw 7 to threadably rise and fall along the mounting frame 8, and then the bottom end of the adjusting screw 7 is driven to rotate along the adjusting plate 37, thereby driving the two adjusting plates 37, the heating roller 16 located above, and the adjusting bevel gear 43 to rise and fall synchronously. At the same time, each limit rod 51 is driven to slide along the corresponding limit groove, and the mounting block 47, the rotating drum 46, and the mounting bevel gear 45 on the adjusting plate 37 are driven to rise and fall synchronously, and then the rotating drum 46 is driven to slide and rise along the adjusting connecting rod 44, thereby driving each limit long groove to slide along the corresponding limit long strip 48. In this way, it is not only convenient for the later production of electrode sheets of different thicknesses to flexibly adjust the spacing between them, and convenient for the later processing and production of electrode sheets, but also simple to operate, highly practical, and conducive to promotion.
