Description

Technical Field

[0001] The utility model relates to the technical field of inner lining paper for cigarettes, in particular to a trimming device for inner lining paper for cigarettes. Background Art

[0002] Cigarette lining paper refers to the aluminum foil used inside cigarette boxes to protect cigarettes. Aluminum foil has high barrier properties against light, gas, and water and is anti-corrosive. It can prevent the smell of cigarettes from emitting and at the same time prevent the smell of cigarettes from corroding other items. It can resist moisture and effectively prevent moisture, thereby preventing cigarettes from mildewing in a humid environment. In the existing processing, the lining paper needs to be trimmed to ensure its flatness;

[0003] Publication No. CN212424890U discloses a trimming device for cigarette liner paper. The product continues to move through the conveyor belt. When it touches the micro switch of the flattening mechanism, the motor is powered on and rotates forward, and the retractable flattening block is pressed down. After pressing down for a certain period of time, the motor loses power and reverses, and the retractable flattening block rises. The product can continue to move until it passes through the processing channel and is stored in the export reel. Multiple processes greatly improve product quality, and the automated operation mode reduces manpower input and shortens the production period.

[0004] However, the above-mentioned trimming device for cigarette liner paper still has the following problems during actual use: although the liner paper is flattened by a lifting flattening block, the liner paper needs to remain still for a period of time during the entire flattening process, which affects the efficiency of processing and trimming. At the same time, a single flattening method cannot remove the wrinkles of the liner paper, and the flattening block is not in contact with the liner paper throughout the whole process, which can easily cause omissions and untrimmed conditions during the movement of the liner paper.

[0005] Therefore, we have proposed a trimming device for cigarette liner paper, so as to solve the above-mentioned problems. Utility Model Content
