Vertical tobacco shred recovery and air pressure regulation integrated device, and cigarette making and tipping machine combination process wind power and dust removal system thereof

Abstract

The invention discloses a vertical tobacco shred recovery and air pressure regulation integrated device, and a cigarette making and tipping machine combination process wind power and dust removal system thereof, and relates to the technical field of tobacco shred recovery. The device comprises a collecting cylinder, an air inlet pipe and an air discharge pipe are coaxially mounted in the collecting cylinder, the air inlet pipe is positioned below the air discharge pipe, a spiral flow guide plate is arranged in the air inlet pipe in the axis direction of the air inlet pipe, a distance between the air inlet pipe and the gas discharge pipe is large enough for tobacco shreds to be thrown to the inner wall of the collecting cylinder under the action of centrifugal force after being discharged from the top end of the air inlet pipe, a material baffle plate is arranged between the outer wall surface of the air discharge pipe and the inner wall surface of the collecting cylinder, an improved butterfly valve with a flow distribution plate is arranged in the air discharge pipe, and a collecting bucket is arranged between the air inlet pipe and the collecting cylinder. Resistance increase andpressure regulation can be achieved through the integrated device, and useful components which are the short tobacco shreds are separated in a branch pipe which is directly connected with a cigarettemaking machine and provided with dusts and the short tobacco shreds and sent back to the cigarette making machine for reuse, so the production raw material is saved.

Description

technical field [0001] The invention relates to the technical field of shredded tobacco recycling, in particular to a vertical shredded tobacco recycling and air pressure adjustment integrated device and a process wind and dust removal system of a crimping unit. Background technique [0002] In the current cigarette industrial production, the transportation of shredded tobacco is mainly completed by process wind. In the existing process wind and dust removal system, the process wind branch pipes connecting each unit are finally connected to the process wind main pipe through cluster pipes. Since shredded tobacco and dust are inevitably brought into the airflow in each branch pipe, in the past, a dust removal device was installed at the end of the main pipe for centralized dust removal before discharge. [0003] In the rolling and splicing unit, the cigarette making machine and the tipping machine are respectively connected to a branch pipe. During the production process of t...

Problems solved by technology

[0003] In the rolling and splicing unit, the cigarette making machine and the tipping machine are respectively connected to a branch pipe. During the production process of the cigarette making machine, the shredded tobacco is adsorbed on the paper tape by the negative pressure wind force. It is inevitable that some short shredded tobacco will be sucked into the branch pipe. In addition to the short tobacco shreds, there are also impurities such as floating filaments, short fibers and debris in the mixture obtained by separating through the dust removal device , leading to the inability to recycle the short shredded tobacco, thus causing a large waste

[0004] In addition, in the existing process wind and dust removal system of the cigarette making machine, since the wind pressure of the pipe of the cigarette making machine is lower than that of the pipe of the machine, in order to balance the wind pressure, the pipe of the machine usually only needs to be installed with ordinary Butterfly valve, while the pipeline of the cigarette machine needs to use a wind pressure balancer to achieve a wider range of wind pressure adjustment, such as an electric wind pressure balancer disclosed in Chinese patent 201210394346, the electric wind pressure balancer is used for Increase pipeline resistance and reduce pipeline wind pressure. Secondly, when the pipeline wind pressure fluctuates, the wind pressure is adjusted to the set range. When using the electric wind pressure balancer to regulate the pipeline wind pressure, the guide body in the valve body needs to be relatively Moving within a large stroke range, the control response speed needs to be improved and the electric air pressure balancer is large in size and inconvenient to install. In addition, there is no good linear proportional relationship between the flow of the balancer and the opening of the valve. Control accuracy needs to be improved
