The pinch roll mechanism 5 includes a left pinch roll belt assembly 51 and a right pinch roll belt assembly 52 which are symmetrically arranged left and right. The left pinch roll belt assembly 51 and the right pinch roll belt assembly 52 are connected by an adjusting assembly 53 to form a feeding channel. The rear ends of the left pinch roll belt assembly 51 and the right pinch roll belt assembly 52 are connected to a synchronous driving assembly 54 arranged in the machine body 1. The synchronous driving assembly 54 can cooperate with the adjusting assembly 53 to adjust the distance between the left pinch roll belt assembly 51 and the right pinch roll belt assembly 52, and at the same time can also drive the left pinch roll belt assembly 51 and the right pinch roll belt assembly 52 to synchronously enter or exit the working state.
[0034] The left pinch roll belt assembly 51 is composed of an H-shaped fixing frame 511, a first driving wheel 512, a first driven wheel 513 and a first pinch roll belt 514. The two ends of the fixing frame 511 are respectively rotatably connected with a first driving wheel 512 and a first driven wheel 513.
