Description

Technical Field

[0001] The utility model relates to the field of blade cleaning equipment, in particular to a filter rod forming machine cutter head blade cleaning device and a filter rod forming machine. Background Art

[0002] During the high-speed operation of the filter rod forming machine, the filter rod strips are transported to the cutter head cutting device through the filter rod strip guide tube, and then the crank connecting rod device drives the trumpet mouth to support the filter rod strips to the cutting position. The transmission device in the filter rod forming machine drives the cutter disc to make the blade pass through the trumpet mouth gap to cut the filter rod strips, making it a filter rod of a certain length. Since the filter rod strips are usually acetate fibers and added with adhesives such as solidified glycerin, hot melt adhesive and cold glue, the blades are often attached with debris such as iron shavings and adhesives, which affects the cutting effect of the filter rod strips and causes product quality problems such as uneven cross-section and dirtiness of the filter rods.

[0003] In order to improve the cleanliness of the blade when cutting the filter rod, the utility model patent with the authorization announcement number CN210876399U discloses a blade dirt removal device, including two cleaning brushes arranged opposite to each other, the handles of the cleaning brushes are fixed by a bracket, a high-pressure air pipe is arranged in the handles of the cleaning brushes, and a blowing hole is arranged at the front end of the handles of the cleaning brushes, the blowing hole is connected to the high-pressure air pipe, the blade is driven to rotate by the knife disc, and the knife disc can drive the blade to rotate between the two cleaning brushes, the blade passes between the two cleaning brushes, brushes off the dirt attached to the surface of the blade, and at the same time, high-pressure air is blown out from the front end of the cleaning brush to clean the powder on the surface of the blade. The device can clean the blade in time during the operation of the filter rod forming equipment, avoid dirt adhering to the filter rod cut, and improve product quality and forming efficiency. However, since the device does not effectively fix the cleaning brush, there will be a defect that the cleaning brush will fall due to friction and backblowing force. In addition, the device does not have a blade protection structure, which poses a safety hazard. Utility Model Content
