[0028] In this embodiment: the flattening feeding mechanism includes a feeding roller 21 arranged on the frame 1, and a worm gear 22 is installed at the rear end of the feeding roller 21 through the frame 1. The feeding rollers 21 are arranged in multiple groups at intervals, and the feeding rollers 21 are rotatably connected to the frame 1.
