After that, it passes through the inside of the limiting ring. Then, the clamping jaws are activated to clamp and fix the paper tube at one end of the fixing frame. After that, the motor is started to make the belt move. The movement of the belt causes the threaded rod to rotate and the moving frame to move, so that the fixing frame contacts one end of the paper tube. Furthermore, in cooperation with the clamping jaws, the paper tube is fixed, realizing the function of limiting and fixing the paper tube before and after cutting. Moreover, it is simple and convenient to use and has strong practicability. Brief Description of the Drawings
