Description

Technical Field

[0001] This invention belongs to the field of cigarette technology, specifically relating to a smoke removal device for a suction chamber. Background Technology

[0002] After cutting long cigarettes into double-length cigarettes, the cigarette rolling machine uses a first-cutting wheel to further divide the double-length cigarettes into two equal-length short cigarettes. A separating wheel then separates these short cigarettes to create space for the double-length filter rods. The double-length filter rods are then joined with the two short cigarettes on a merging wheel and passed to a converging wheel. The converging wheel brings the equal-length short cigarettes and double-length filter tips together and aligns them with the wheel system. A paper-cutting wheel attaches glued tipping paper to the double-length filter rods and cigarettes on the converging wheel. A joining wheel then joins them together to form a double-length cigarette. Finally, a second-cutting wheel cuts the double-length cigarettes into finished cigarettes. However, in actual cigarette production, tobacco dust can adhere to the tipping paper and filter rods. After joining, this tobacco dust can get trapped in the cigarette filter, harming consumers and causing dissatisfaction.

[0003] Analysis of cigarette-making principles reveals that the inherent properties of tobacco mean that dust generation occurs throughout the entire cigarette-forming process. Dust buildup in the filter tip primarily occurs before the cigarette is joined, especially at the junction of the merging and combining rollers, when the float ring of the combining roller pushes the cigarette sections together for alignment, at the junction of the combining roller and the joining roller, and during the mixing of suspended dust before joining. Currently, various cigarette-making machines primarily handle dust by using negative pressure suction within each transfer roller to remove it, which is then discharged through the main suction pipe. This method is effective for small amounts of easily removed dust, but its effectiveness diminishes under high-speed operation due to the pushing action of sections on the combining roller and the dust ejected by centrifugal force. Summary of the Invention

[0004] To address the technical problem of difficult-to-remove smoke droplets generated before splicing in existing technologies, this invention provides a smoke droplet removal device with a suction chamber. This device can individually extract smoke droplets generated on the merging wheel, the combining wheel, and the splicing wheel due to the pushing and centrifugal force of the cigarettes in each group, thereby reducing the occurrence of suspended smoke droplets sticking to the tipping paper during splicing.

[0014] Furthermore, the two sides of the suction chamber housing are respectively supported and fixedly installed below the converging wheel and the integrating wheel by the first fixed support shaft and the second fixed support shaft. The first fixed support shaft and the second fixed support shaft are respectively connected to the cigarette machine body, and the positional relationship between the suction chamber housing and the converging wheel and the integrating wheel can be adjusted by adjusting the position of the first fixed support shaft and the second fixed support shaft.

[0033] In one embodiment, the upper ends of the first suction chamber A, the second suction chamber B, and the third suction chamber C are suction ports, and all three suction ports are composed of a perforated plate structure. The mesh diameter of the perforated plate structure is no greater than 2 / 3 of the diameter of the cigarette, and the mesh is arranged in an equidistant array or staggered arrangement.

[0034] In one embodiment, the air inlet of the second air intake chamber B is provided with an arc-shaped groove, the shape of which is adapted to the cleaning brush 4.

[0035] In one embodiment, the shovel 10 has shovel teeth on both sides that mate with the surface of the upper composite wheel body, with a gap between the shovel teeth and the surface of the wheel body; the middle shovel tooth of the shovel 10 mates with the annular groove of the composite wheel 2, and the top of the middle shovel tooth is higher than the bottom of the cigarette groove of the composite wheel 2, for removing filter rods, short cigarettes or other debris from the cigarette groove.

[0036] In one embodiment, one end of the main suction pipe 5 is connected to an external metal pipe below the suction chamber housing, and the other end is connected to the main negative pressure cavity of the cigarette machine. A solenoid valve 7 is provided on the main suction pipe to control the on / off of the negative pressure suction of the suction chamber cavity.

[0037] In one embodiment, the two sides of the suction chamber housing are fixedly installed below the converging wheel 1 and the integrating wheel 2 by the first fixed support shaft 601 and the second fixed support shaft 605, respectively.

The three suction chambers have 2mm diameter perforated plates for removing smoke particles with a diameter of less than 2mm.

[0043] The specific working process of this invention:

[0044] Before the cigarette making process begins, the smoke removal device is installed and adjusted according to the positions of the converging wheel 1, the integrating wheel 2, and the twisting wheel 3. The scraper 10 is installed at the suction port of the first suction chamber A. The installation position of the scraper 10 is adjusted through the long groove of the scraper teeth. During the start-up process of the cigarette making equipment, when the finished cigarette passes through the smoke exit wheel detector, the solenoid valve 7, which controls the negative pressure suction of the suction chamber 6, is connected to the negative pressure. At this time, a negative pressure is formed in the entire smoke removal device, and the device starts to work. The falling smoke generated between the converging wheel 1 and the integrating wheel 2 due to the push of the filter rod and the short branch is sucked away by the third suction chamber C and the second suction chamber B. The smoke and accumulated glue adhering to the surface of the integrating wheel 2 are brushed off by the cleaning brush 4 and then sucked in by the second suction chamber B. The smoke generated when the cigarette is handed over between the integrating wheel 2 and the rubbing wheel 3, as well as the smoke brought under the two wheels by the centrifugal force of the integrating wheel 2, are sucked in by the first suction chamber A and the second suction chamber B. During this process, the scraper 10 removes the filter rod, short branch and other debris that have not been removed, ensuring that the entire suction chamber 6 is not blocked by debris and thus does not affect normal operation. The remaining smoke that is brought into the direction of the rubbing board by the centrifugal force of the rubbing wheel 3, as well as the smoke generated when the cigarette is handed over between the receiving wheel 2 and the rubbing wheel 3 and has not been sucked in by the second suction chamber B, is sucked away by the suction provided by the first suction chamber A or the movement trajectory of the smoke falling into the area of ​​the rubbing wheel and the rubbing board is changed to prevent the smoke from entering the tipping paper and causing trapped smoke.
