Mounting brackets are also provided on both sides of the mounting groove on the upper surface of the worktable, each mounting bracket containing an elastic component. A cutting frame is located at the left end of the upper surface of the worktable, and an electric telescopic rod is provided on the upper surface of the cutting frame. Guide rods are symmetrically inserted on the upper surface of the cutting frame. A mounting block is provided at the output end of the electric telescopic rod, and a slot is formed on one side of the mounting block. The upper surface of the wall has a movable groove, and a pull rod is inserted through the upper surface of the inner wall of the movable groove. A push plate is provided at the bottom end of the pull rod, and a limit block is provided on the bottom surface of the push plate. A second spring is sleeved on the circumferential side of the pull rod. The cutter includes a mounting plate, and a limit groove is provided on the upper surface of the mounting plate. A cutting blade is provided on the bottom surface of the mounting plate. The output end of the servo motor is fixedly connected to one end of the power roller. The first elastic component includes a hollow tube, and a sleeve is sleeved on the circumferential side of the hollow tube. A spring is provided on the bottom surface of the hollow tube. A sliding block is provided on the bottom surface of the hollow tube. A lower pressure roller is rotatably connected to the side of the sliding block. The second elastic component includes a hollow tube, and a sleeve is sleeved on the circumferential side of the hollow tube. A third spring is provided on the bottom surface of the hollow tube. A lower pressure block is provided on the bottom surface of the hollow tube. A lower pressure roller is rotatably connected to the side of the lower pressure block.

[0007] Furthermore, the upper surface of the first sleeve is fixedly connected to the upper surface of the inner wall of the first mounting bracket, the top end of the first spring is fixedly connected to the upper surface of the inner wall of the first sleeve, the first sleeve and the first hollow tube are in telescopic cooperation, the sliding block is set in the sliding groove, the first pressure roller is set in the pressure groove, the second peripheral side of the second pressure roller is in contact with the peripheral side of the power roller, the second hollow tube and the second sleeve are in telescopic cooperation, the top end of the third spring is fixedly connected to the upper surface of the inner wall of the second sleeve, and the upper surface of the second sleeve is fixedly connected to the upper surface of the inner wall of the second mounting bracket.

[0009] This utility model has the following beneficial effects:

[0010] This invention allows for the complete removal of the cutting tool by pulling the lever upwards when the cutting tool is severely worn, which in turn pulls the limiting block out of the limiting groove via the push plate and retracts it into the movable groove. When installing a new cutting tool, the mounting plate is inserted into the slot. The edge of the mounting plate presses against the inclined surface of the limiting block, pushing the limiting block back into the movable groove. When the mounting plate is fully inserted into the slot, the limiting groove and the movable groove are aligned. The spring returns to its original position and pushes the push plate to lock the limiting block into the limiting groove, thus completing the fixation.

[0011] By passing the rubber roll through the bottom edge of the side of the lower pressure roller, and then passing the rubber roll between the second lower pressure roller and the power roller, the first lower pressure roller keeps the rubber roll taut due to the pressure of the first spring to prevent it from loosening due to inertia. The second lower pressure roller, through the elasticity of the third spring and the expansion and contraction of the second sleeve and the second hollow tube, can squeeze the rubber roll to fit against the side of the power roller. Then, the power roller is driven to rotate by the servo motor, so that the second lower pressure roller moves forward for transport. The electric telescopic rod pushes the cutter downward to cut the rubber roll.
