[0052] The existing cigarette packet is different in size specification, and the length of the outer packaging transparent paper also has differences, which leads to the need for frequent adjustment of the cutting device, and the adjustment usually depends on replacing the transmission gear to change the transmission ratio, which is not only time-consuming and laborious but also low in efficiency.

[0053] In order to solve the above problems, combined with Figures 1-4 As shown in the description, the transparent paper pull line cutting device of the embodiment includes a rack 1, a cutting tool 2, a driving device 3 and a speed regulating device.The rack 1 has a left side frame and a right side frame, and the cutting tool 2 is located between the left side frame and the right side frame, and the two ends of the cutting tool 2 are respectively rotatably arranged on the left side frame and the right side frame.The rack 1 is also rotatably connected with a paper guide roller 4, and the paper guide roller 4 is located at the front end of the cutting tool 2, and the transparent paper 100 is pulled to the cutting position of the cutting tool 2 after passing through the paper guide roller 4 for cutting operation.

The spring pressing sheet 24 is small in structure and occupies a small space in the transparent paper pulling and cutting device, thereby avoiding interference with other structures.

[0065] In addition, the end of the spring pressing sheet 24 away from the frame 1 is rotationally provided with a roller 25, and the circumferential side of the roller 25 is in rolling contact with the rotating disc 22. The roller 25 converts the sliding contact between the spring pressing sheet 24 and the rotating disc 22 into rolling contact, thereby protecting the transparent paper 100 and avoiding damage or scratches of the transparent paper 100 during traction and cutting.

[0066] In summary, the speed of the driving motor 34 is controlled by the speed regulating device, and at least the following advantages are achieved:

[0067] 1. Improved adjustment efficiency; when different specifications of products are replaced, the speed of the driving motor 34 can be adjusted by adjusting the speed of the speed regulating device, thereby adjusting the rotating speed of the cutting blade 23;

[0068] 2.
