Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to a cutting blade cleaning and cooling device and control method for a filter tip assembly machine. Background Technology

[0002] Currently, most cigarette filter loading machines use circular cutters to cut cigarettes and filter rods. These circular cutters are mainly divided into stainless steel cutters and alloy cutters. Stainless steel cutters require the use of a grinding wheel to maintain proper sharpness. In actual operation, both types of cutters and grinding wheel surfaces are prone to adhering to impurities such as adhesive residue and paper scraps, severely affecting the cutting accuracy and leading to burrs on the cigarette cut. This is especially pronounced when cutting filter rods made of special materials such as silicone, where impurity adhesion can even prevent normal cutting. Furthermore, the cutter temperature continuously rises during the cutting process, which not only shortens the cutter's lifespan but also causes thermal deformation of the cutting drum guide rail. More importantly, the adhesive residue and debris generated by the cutter can clog the cutting grooves of the cutting drum, continuously increasing the cutting resistance. After prolonged operation, this can easily lead to motor burnout.

[0003] Therefore, there is an urgent need to design a cutting blade cleaning and cooling device and control method for filter tip assembly machines, so as to ensure the quality of cigarette cutting and effectively reduce equipment downtime for maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting blade cleaning and cooling device and control method for a filter tip assembly machine, which can ensure the quality of cigarette cutting and reduce equipment downtime for maintenance.
