After stitching the aluminum strip, when the aluminum strip is stuck on the upper pressure column 47, in order to ensure the normal transmission of the aluminum strip and the downward movement and reset of the upper pressure plate 45, the lifting frame 435 is driven downward by the cylinder 436, and the lifting frame 435 drives the pressure roller 434 to move downward, so that the pressure roller 434 presses down the aluminum strip stuck on the upper pressure column 47.

When it is necessary to maintain the lower roller group 75 on the lower frame 73, the first oil cylinder 79 is started, and the first oil cylinder 79 drives the fixed block 710 to move upward, releasing the squeezing and fixing of the fixed block 710 on the lower frame 73, so that the lower frame 73 can be pulled out through the traction device to maintain the lower roller group 75. ;
