Description

Technical Field

[0001] This invention relates to the field of dust removal technology for packaging machines, and more particularly to a dust removal system for the cigarette supply component of a YB25 / 45 packaging machine. Background Technology

[0002] In cigarette production, the YB25 / 45 packaging machine is the mainstay model in my country's cigarette packaging industry. Cigarettes exit the cigarette machine, pass through the cigarette storage container, and arrive at the cigarette storage section of the packaging machine. Here, they are arranged in a 7*6*7 pattern and pushed into the cigarette delivery box by the cigarette pusher. Inside the box, the cigarettes undergo alignment checks, empty cigarette checks, and missing cigarette checks. Unqualified cigarettes are rejected at the rejection port. Qualified cigarettes are conveyed by the cigarette delivery box conveyor belt to the first and second wheels, completing the wrapping with aluminum foil, label paper, and sealing paper.

[0003] However, because the cigarettes are not fully packaged in the conveyor box, the cigarette cores detach and accumulate between the conveyor belt and the trapezoidal groove of the pulleys during high-speed operation. Furthermore, during maintenance shutdowns, a large amount of cigarette cores, dust, and oil fall into and accumulate between the conveyor belt and the pulleys. When the equipment restarts, this causes the conveyor belt and pulleys to jam, damaging the conveyor belt and the conveyor box. This fault typically occurs during maintenance restarts and is often intermittent and sudden. Once this fault occurs, replacement and repair take approximately 3 hours, increasing maintenance costs and reducing the equipment's effective operating rate. The YB25 / 45 packaging machine cannot address these design flaws by adding detection and cleaning devices, and current technology lacks a satisfactory solution. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal system for the cigarette supply component of a YB25 / 45 packaging machine, which can meet the need to clean up the ash and soot accumulated on the cigarette conveyor belt and the trapezoidal groove of the pulley.
