In the cigarette production process, the tipping paper is transported to be an important process, the tipping paper is a roll, and when the last roll is about to run out, the paper changing operation needs to be carried out: the backup tipping paper is wound on the platen roller 4 in advance. Before the last tipping paper is used up, the cigarette system automatically adjusts the position of the paper guide roller 8 according to the detected information, so that the paper guide roller 8 is in friction contact with the paper pressing roller 4. The tipping paper wound on the paper pressing roller 4 is wound on the paper leading roller 8 under the action of friction force; after the tipping paper is stably moved, the paper guiding roller 8 is reset, and the paper guiding roller 8 conveys the tipping paper forwards continuously under the rotating acting force of the driving part.
A paper guide device described below is used to mount the platen roller 4. The platen roller 4 has two positions: a home position and a working position. In the home position, even if the paper-drawing roller 8 is displaced to a position just before the platen roller 4 comes into contact, the platen roller 4 cannot come into contact with the paper-drawing roller 8. The home position is mainly used for manually winding the standby tipping paper onto the paper pressing roller 4 first. In the working position, if the paper guide roller 8 is displaced to a position just before the platen roller 4 comes into contact, the platen roller 4 can come into contact with the paper guide roller 8.
The structure of the paper guiding device provided by the embodiment of the invention is described in detail below.

The operation of the threading device is described below.
First, according to the above-assembled paper feeding device, the platen roller 4 is brought into close contact with the paper feeding roller 8 in a normal state by the elastic force of the compression spring 17, and a sufficiently large pressing force is generated between the platen roller 4 and the paper feeding roller 8.
Before splicing the tipping paper, the operating handle 6 is rotated clockwise, thereby rotating the central shaft 31 and the eccentric part 33. The eccentric member 33 is pressed against the platen 5 by the eccentric action of the eccentric member 33, and the platen roller 4 is separated from the pickup roller 8. The standby tipping paper is then passed through the gap between the pick-up roller 8 and the platen roller 4 to the interior of the receiving cavity 11 of the paper storage cover 1. Finally, the handle ball 10 is pulled back anticlockwise, and the tipping paper is clamped between the paper guide roller 8 and the paper pressing roller 4. In the process, the tipping paper does not need to be wound by 8 circles of the paper guide roller, so that the waste phenomenon of the tipping paper is reduced.
When splicing the tipping paper, the paper guide roller 8 rotates to drive the paper pressing roller 4 to rotate, and the tipping paper is fed into the paper storage cover 1 by resultant force. The tipping paper is then attracted by the splice roll and transported on to the desired station. In the splicing process, the tipping paper can not be rolled on the surface of the paper guide roller 8, so that the gap between the paper guide roller 8 and the splicing roller is more stable, and the splicing success rate is improved.
After tipping paper splicing, tipping paper waste generated by splicing can be stored in the accommodating cavity 11 of the paper storage cover 1 in a corrugated manner, and tipping paper rolls can not be generated, and only can the tipping paper waste be manually taken out, so that the potential safety hazard caused by cutting of the tipping paper rolls is reduced.
