When feeding, the material belt is supported by the support guide roller in the side support plate, which reduces the friction generated by the material belt during feeding. At the same time, the support of the support guide roller effectively prevents the material belt from sagging and being bent and deformed due to gravity. At the same time, the height difference between the support guide roller and the support plate restricts the material belt between the support plates, preventing the material belt from being bent and limiting the position of the material belt, thereby reducing the friction when the material belt moves.
