Tubular clamp module and system thereof for roll material cutting machine

A tubular clamp module for a roll material cutting machine, comprising:

• a pair of supports, a top end of each support having a slope;
• a pair of tubular plates, each tubular plate corresponding to each support and disposed on an upper portion of the corresponding support, so that a bottom of the tubular plate is disposed adjacent to the slope, an upper end of the tubular plate being capable of sliding in an overlapped manner so as to clamp a roll;
• a pair of support rods, each support rod corresponding to each slope and slidably disposed on the corresponding slope respectively, for supporting a circumference of the tubular plates;
• a pair of support rod driving wheels, each driving wheel corresponding to each support and respectively disposed under the corresponding support;
• a pair of support rod driving belts, each support rod driving belt corresponding to each slope and support rod driving wheel, and respectively crossing over the corresponding slope and the support rod driving wheel, the pair of support rod driving belts being connected to the corresponding support rods, and used to drive the support rods to slide on the slopes;
• and
• a pressing belt, crossing over the tubular plates, and applying forces downward by two ends of the pressing belt, thereby providing a tubular radial clamp force by using the tubular plates.
