Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery and equipment, and more particularly to an automatic cleaning device for an observation window of a cutter disc cover of a shredder. Background Art

[0002] The cutter is a key piece of equipment in a tobacco production line. Its task is to cut processed tobacco into shredded tobacco of a specific width. Therefore, the cutting process inevitably generates a significant amount of smoke and dust. The Tobspin rotary cutter cover encloses the cutter disc and discharge port within the equipment, providing sound insulation and protection. However, to facilitate operator observation of equipment conditions such as the cutter disc's operation and the sharpening of the cutter blades, the Tobspin cutter cover features a circular plexiglass observation window with a diameter of 450mm and a sector-shaped plexiglass observation window with a diameter of 155mm-180mm and a 75-degree angle. However, in actual operation, the rotating airflow of the cutter disc carries a small amount of tobacco shreds through the discharge port and surrounding gaps, clinging to the inner surface of the cutter cover's observation window, obstructing the operator's observation of equipment operation.

[0003] At present, the cleaning of the observation window of the cutter head cover mainly relies on manual work. After each batch of tobacco production is completed, the machine is stopped, the cutter head cover is opened, and the smoke dust adhering to the inner surface of the observation window is swept off with a brush, which increases the labor intensity of the operator.

[0004] Therefore, how to provide an automatic cleaning device for the observation window of the cutter disc cover of a shredder has become a technical problem that urgently needs to be solved in this field. Utility Model Content
