[0002] One-way transparent film is a special film material, usually used to make one-way transparent window stickers, advertising stickers and other products. It has the characteristics of being transparent from one side but not from the other side. In the production process of one-way transparent film, large rolls of raw film are often produced first, and then the raw film is cut into small widths and then rolled and packaged. Here, a slitting and winding device will be used.

[0003] The slitting knife groups of the existing slitting and winding devices are mostly fixed in position using multiple bolts. When adjusting the spacing of the slitting knives, it is necessary to loosen multiple bolts and then adjust the relative position of the slitting knives. After the adjustment is completed, the multiple bolts are fixed again. The process is cumbersome and inconvenient.

[0004] Based on the above, the purpose of the present invention is to provide a single-transmission film slitting and winding device to solve the above problems. Utility Model Content

The slitting assembly includes a mounting roller 4, which is rotatably connected to the mounting frame, and a quick-release structure can be provided to facilitate the removal of the mounting roller. The quick-release structure of the roller is a mature prior art and will not be elaborated here. A guide groove 5 is provided on the mounting roller 4, and the guide groove is a straight groove. A plurality of sliders 6 are slidably connected in the guide groove 5. The mounting roller 4 is provided with an adjustment mechanism for driving multiple sliders 6 to move equidistantly. A mounting ring 7 corresponding to the number of sliders 6 is slidably connected to the mounting roller 4, and the mounting ring 7 is fixedly connected to the slider 6. A circular knife 8 is installed on the mounting ring 7, and the circular knife can be clamped in the form of a splint, or a circular knife with a mounting hole can be selected, and it can be fixed to the mounting ring by means of bolts and other tools in combination with the mounting hole of the circular knife. The mounting frame 1 is provided with a driving mechanism for driving the mounting roller 4 to rotate.

[0028] Furthermore, the adjustment mechanism includes a driving roller 9 rotatably connected to the mounting roller 4, and a plurality of driving grooves 10 are formed on both sides of the driving roller 9. The number and position of the driving grooves 10 on both sides correspond to each other, and the inclination amplitude of the driving grooves 10 on both sides gradually increases from the inside to the outside, and the spacing between the multiple driving grooves on the cross section of the driving roller is always the same. The slider 6 is provided with an insertion rod 11 with one end fixedly connected thereto, and the other end of the insertion rod 11 is inserted into the driving groove 10. The mounting roller 4 is provided with a switching module for switching the mounting roller 4 and the driving roller 9 between a fixed connection and a rotating connection.

[0029] Furthermore, the switching module includes a driving rod 12 fixedly connected to the driving roller 9, a switching disk 13 and a connecting block 14 are provided on the driving rod 12, the connecting block 14 is fixedly connected to the driving rod 12, a connecting groove 15 for inserting the connecting block 14 is provided on the switching disk, the connecting block and the connecting groove are both polygonal structures, a plurality of splines 16 are formed on the switching disk, a switching groove 17 for inserting the switching disk and the spline 16 is provided on the mounting roller 4, and a chamfer is provided on the side of the spline facing the switching groove.

[0030] Furthermore, a limit nut 18 is threadedly connected to the driving rod 12 .

[0031] Furthermore, the driving mechanism includes a motor 19 fixedly connected to the mounting frame 1 , and a pulley transmission assembly 20 is provided between the output shaft of the motor 19 and the mounting roller 4 .

[0032] Furthermore, a support roller 21 is rotatably connected to the mounting frame 1 .

[0033] Working principle: When the spacing of the slitting knives needs to be adjusted, the limit nut 18 is rotated to keep it away from the switching disk 13, and then the switching disk 13 is pulled out of the switching groove 17. A handle can be added to the switching disk 13 to facilitate pulling it out. At this time, the driving rod 12 can be rotated to drive the driving roller 9 to rotate. During the rotation of the driving roller 9, the driving groove 10 and the insertion rod 11 drive the slider 6 to move along the trajectory of the guide groove 5, and then the spacing between the multiple circular knives 8 needs to be adjusted. After the spacing adjustment of the circular knives 8 is completed, the switching disk is inserted into the switching groove 17. At this time, the inserting teeth 16 are engaged with the switching groove 17 and the connecting block 1 4 is inserted into the connecting groove 15, and then the limiting nut 18 is rotated in the opposite direction until the limiting nut 18 abuts against the switching disk 13. The limiting nut 18 can limit the switching disk 13 to prevent it from escaping from the connecting groove 15. At this time, the installation roller 4 can be driven to rotate by the motor 19 and the pulley transmission assembly 20, thereby driving the circular knife 8 to rotate and cut the raw material film. The supporting roller will support the raw material film to make the cutting effect more stable. The driving roller 9 rotates synchronously with the installation roller 4 under the action of the connecting block 14, the connecting groove 15, the connecting disk and the switching groove 17 to prevent the position of the circular knife 8 from being offset during the cutting process.
