Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making machinery and equipment, in particular to a glue accumulation-proof paper cutting wheel for a cigarette making machine. Background Art

[0002] In the cigarette production process, tipping paper perforation is widely used as an effective means to reduce tar content in cigarette smoke. This technology dilutes the smoke during smoking by perforating the cigarette filter, thereby reducing the amount of tar inhaled and mitigating its negative impact on the human body and the environment. Currently, tipping paper perforation technologies are mainly divided into two types: in-line laser perforation of cigarettes and laser pre-perforation of tipping paper. Laser pre-perforation of tipping paper has gradually become the mainstream in the industry due to its advantages such as low investment, stable and uniform perforation, and no impact on equipment operating speed.

[0003] However, the application of the laser pre-punching technology for tipping paper has also exposed some problems, especially in the tipping paper cutting and pasting process. In order to ensure that the cigarettes are firmly pasted after being twisted and spliced, the cutting part of the laser pre-punched tipping paper tape needs to be glued first. Then the blade of the paper cutting wheel and the paper cutter of the paper cutting roller perform a shearing motion to cut the laser pre-punched tipping paper tape into pieces of tipping paper. The negative pressure pores on the outer circle of the paper cutting wheel absorb the tipping paper tape and the tipping paper pieces and guide them to be transported forward. The tipping paper tape, the tipping paper pieces and the paper cutting wheel operate synchronously. After running a distance H, the tipping paper pieces are pasted one by one on the "group cigarette" (see the principle). Figure 6 After gluing, the glue on the laser-perforated tipping paper easily leaks through the laser pre-perforated holes onto the surface of the paper cutting wheel. The suction force of the negative pressure holes in the paper cutting wheel further exacerbates the leakage, leading to serious glue accumulation on the paper cutting wheel. This not only affects the flatness and conveying stability of the tipping paper, but also easily causes quality problems such as tipping paper skew, filter wrinkles, and air leakage, thereby reducing the overall quality of cigarette products.

[0004] Furthermore, glue buildup on the cutting wheel can clog the negative pressure vents and their passages, affecting the efficient transfer of laser-perforated tipping tape and paper sheets. This increases the frequency of equipment downtime for cleaning and maintenance, reducing the overall efficiency and economic benefits of the production line. These issues have become key factors restricting cigarette production efficiency and product quality.

[0005] Therefore, in summary, how to provide a paper cutting wheel with a new structure to solve the problem of glue accumulation is a technical problem that needs to be solved urgently in this field. Utility Model Content
