[0026] The positioning assembly includes a first roller 3, with both ends of the outer surface of the first roller 3 rotatably connected to the interior of the first vertical plate 1. Positioning plates 4 are slidably connected to both sides of the outer surface of the first roller 3. A first electric push rod 5 is fixedly connected to the inner side of the positioning plate 4. A limit plate 6 is fixedly connected to one end of the first electric push rod 5. A first fixing bolt 7 is threaded onto the upper surface of the positioning plate 4. Several positioning grooves adapted to the first fixing bolt 7 are formed on the upper surface of the first roller 3. The position of the positioning plate 4 is adjusted according to the width of the whiteboard paper. The first fixing bolt 7 is screwed into the corresponding positioning groove for fixation. Then, the first electric push rod 5 is activated to fine-tune the position of the limit plate 6, making the limit plate 6 fit against the edge of the whiteboard paper, thus positioning the whiteboard paper. This ensures that the whiteboard paper remains centered during transport, preventing offset and inaccurate slitting, which would affect slitting quality and maintain overall production efficiency, thus avoiding waste and scrap of the whiteboard paper.

[0027] The guide assembly includes a locking rod 8, the inner side of which engages with the inside of a slot. A locking plate 9 is fixedly connected to the upper surface of the locking rod 8, and a second electric push rod 10 is fixedly connected to the outer side of the locking plate 9. One end of the second electric push rod 10 is fixedly connected to a push plate 11, so that the locking rod 8 engages with the appropriate slot, and the two sides of the whiteboard paper are positioned inside the locking plate 9. Then, the second electric push rod 10 is activated to adjust the position of the push plate 11, so that it fits against the edge of the whiteboard paper, thereby further limiting the position of the whiteboard paper. On the one hand, it keeps the paper in place for conveying, and on the other hand, it can be moved to a position slightly below the cutter 17 to avoid the cutting position being too high and affecting the cutting quality.

[0028] A second vertical plate 12 is fixedly connected to one end of the outer side of the flat plate 2. A cutting component is fixedly installed on one side of the second vertical plate 12. A connecting plate 13 is fixedly connected to the back of the second vertical plate 12. A third vertical plate 14 is fixedly connected to the back of the connecting plate 13.

A second fixing bolt 18 is threadedly connected to the upper surface of the cutter 17. Several fixing grooves that are adapted to the rotating rod 16 are opened on the upper surface of the rotating rod 16. The position of the cutter 17 is adjusted as needed, and the second fixing bolt 18 is screwed into the corresponding fixing groove for fixation. Then, the first motor 15 is started by connecting an external power source to drive the rotating rod 16 to rotate, thereby causing the cutter 17 to rotate and press down to cut the whiteboard paper.

[0030] The winding assembly includes a second motor 19, one side of which is fixedly mounted on one side of the third upright plate 14. The output end of the second motor 19 is fixedly connected to a first connector 20. A second roller 21 is snapped into the inner side of the first connector 20. A second connector 22 is snapped into one end of the second roller 21. When an external power source starts the second motor 19, it drives the second roller 21 to rotate via the first connector 20, thereby winding up the cut whiteboard paper and pulling the whiteboard paper conveyor.

[0031] The moving component includes a cylinder 23. One side of the cylinder 23 is fixedly connected to the inner side of the connecting plate 13. One end of the cylinder 23 is fixedly connected to a moving plate 24. A roller 25 is fixedly connected to the lower surface of the moving plate 24. The top of the inner side of the moving plate 24 is rotatably connected to one side of the second connecting head 22. When the cylinder 23 is activated, it pushes the moving plate 24 to move outward, which allows the moving plate 24 to drive the second connecting head 22 to disengage from the second roller 21, thereby facilitating the unloading of the whiteboard paper wound on the surface of the second roller 21.

[0032] Working steps: First, adjust the position of the positioning plate 4 according to the width of the whiteboard paper, and use the first fixing bolt 7 to screw it into the corresponding positioning groove for fixation. Then, start the first electric push rod 5 to fine-tune the position of the limiting plate 6 so that the limiting plate 6 is in contact with the edge of the whiteboard paper. Next, make the locking rod 8 engage in the appropriate locking groove, and then make both sides of the whiteboard paper inside the locking plate 9. Then, start the second electric push rod 10 to adjust the position of the top push plate 11 so that it is in contact with the edge of the whiteboard paper. Next, adjust the position of the cutter 17 as needed, and fix the second fixing plate 11 in the correct position. The bolt 18 is screwed into the corresponding fixing groove for fixation. Then, the external power supply starts the first motor 15, which drives the rotating rod 16 to rotate, thereby causing the cutter 17 to rotate and press down to cut the whiteboard paper. Finally, the external power supply starts the second motor 19, which drives the second roller 21 to rotate through the first connector 20, thereby winding up the cut whiteboard paper. Subsequently, the cylinder 23 is started to push the moving plate 24 to move outward, which allows the moving plate 24 to drive the second connector 22 to disengage from the second roller 21, thereby facilitating the unloading of the whiteboard paper wound on the surface of the second roller 21.
