[0017] (1) The utility model is provided with a placement table, a lifting frame, two movable frames and a cutting disc. When in use, a worker places the long toilet paper roll to be cut in a placement groove opened in the center of the top surface of the placement table, and then starts the first servo motor through the control panel to drive the first bidirectional lead screw passing through the reserved through groove to rotate. Because the placement table is symmetrically provided with clamping plates on both sides, and the first guide sliding block fixedly installed at the bottom end of the clamping plate is embedded in the first guide sliding groove opened on the top surface of the fixed bottom plate, and the first bidirectional lead screw is sleeved in the first lead screw sleeve fixedly installed in the clamping plate, the two clamping plates can be driven along with the rotation of the first bidirectional lead screw. The first guide slot moves relative to each other until the two clamping plates clamp and fix the two ends of the long toilet paper roll. Then the user can use the second servo motor to drive the second bidirectional lead screw installed in the second guide slot opened in the lifting frame to rotate. Because the two movable plates are symmetrically welded with the second guide sliders on the top surfaces, and the second lead screw sleeve fixedly installed in the second guide slider is sleeved with the second bidirectional lead screw, the two movable plates can be driven to move an equal distance relative to each other along the second guide slot as the second bidirectional lead screw rotates.

The output of the third servo motor A cutting disc is fixedly installed on the rotating shaft installed at the output end, so the distance moved by the cutting disc each time can be controlled by controlling the distance moved by the movable plate each time through the control panel, thereby realizing the regulation of the slitting distance of the toilet paper roll. After the two movable plates move a certain distance each time, the control panel can start the electric telescopic rod installed in the center of the top surface of the processing box. The output end of the set electric telescopic rod is connected and installed in the center of the top surface of the lifting frame, and the guide sliding rod symmetrically welded on the top surface of the lifting frame is sleeved in the guide sliding sleeve symmetrically fixed on the top surface of the processing box. Therefore, the electric telescopic rod can drive the lifting frame together with the movable plate and the rotating cutting disc along the guide sliding sleeve The rod descends in the direction of the rod, thereby realizing the synchronous slitting processing on both sides of the long toilet paper roll. By repeating this cycle, the long toilet paper roll can be evenly cut into several small toilet paper roll products with equal distance. After the processing is completed, the electric telescopic rod drives the lifting frame to reset, and the worker opens the protective box door installed on one side of the processing box by the hinge, and then takes out the slit multiple sections of toilet paper roll.

[0038] Working principle: The utility model is provided with a placement table 4, a lifting frame 9, two movable frames and a cutting disc 7. When in use, a worker places the long toilet paper roll to be cut in the placement groove 36 opened in the center of the top surface of the placement table 4, and then starts the first servo motor 14 through the control panel 17 to drive the first bidirectional lead screw 3 passing through the reserved through groove 5 to rotate. Because the placement table 4 is symmetrically provided with clamping plates 2 on both sides, and the first guide slider 30 fixedly installed at the bottom end of the clamping plate 2 is embedded in the first guide slide groove 29 opened on the top surface of the fixed bottom plate 1, and the first bidirectional lead screw 3 is sleeved in the first lead screw sleeve 31 fixedly installed in the clamping plate 2, so as the first bidirectional lead screw 3 rotates, the two clamping plates 2 can be driven to move relative to each other along the first guide slide groove 29 , until the two clamping plates 2 clamp and fix the two ends of the long toilet paper roll, and then the user can drive the second bidirectional lead screw 11 installed in the second guide slot 22 opened in the lifting frame 9 to rotate through the second servo motor 13. Because the two movable plates 25 are symmetrically welded with the second guide slider 23 on the top surface, and the second lead screw sleeve 24 fixedly installed in the second guide slider 23 is sleeved with the second bidirectional lead screw 11, the two movable plates 25 can be driven to move relative to each other along the second guide slot 22 by the rotation of the second bidirectional lead screw 11.
