The invention discloses rubber tube cutting equipment capable of avoid saw web damage. The rubber tube cutting equipment comprises a rack and a stand column, wherein two fixing mechanisms are symmetrically arranged on the rack; each fixing mechanism comprises two symmetrically arranged fixing blocks; a lead screw is arranged on each fixing block in a penetrating manner; an arc-shaped clamping block is arranged at one end of each lead screw, and the other end of the lead screw is fixed through a nut; the two arc-shaped clamping blocks are arranged in an opposite manner; a mechanical arm is hinged to the top end of the stand column; a motor is arranged in the mechanical arm; a saw web connected with the motor is arranged at the non-hinge end of the mechanical arm; a slit for heat dissipation is arranged on the saw web; an air cylinder matched with the mechanical arm is arranged on the rack. The rubber tube cutting equipment solves the problems that the existing rubber tube cutting machine can cut rubber tubes of the same size only and the heat dissipation property of the saw web is poor.
