As shown in fig. 1 and 2, the cigarette machine glue-spraying cigarette foam removing device of the present disclosure comprises an air suction hood 1. The air suction cover 1 is provided with an air suction gap 11 extending along the glue spraying direction of the glue spraying nozzle 01. The air suction gap 11 comprises a first air guide side wall 111, a second air guide side wall 112, a wind shielding bottom wall 113, a first air inlet, a second air inlet and a glue spraying opening 114.

The first wind guiding side wall 111 and the second wind guiding side wall 112 are disposed oppositely, and the first wind guiding side wall 111 and the second wind guiding side wall 112 are respectively located at two ends of the wind shielding bottom wall 113. One end of the first air guiding sidewall 111, the second air guiding sidewall 112 and the bottom wall 113 along the extending direction of the air suction gap 11 form a first air inlet. The other ends of the first air guiding sidewall 111, the second air guiding sidewall 112 and the wind shielding bottom wall 113 along the extending direction of the wind suction gap 11 form a glue spraying opening 114. That is, the first wind guiding sidewall 111, the second wind guiding sidewall 112 and the wind shielding bottom wall 113 form a first wind inlet and a glue spraying port 114 which are oppositely arranged. The glue spraying port 114 can be used for the glue spraying nozzle 01 to glue the cigarette paper. During specific implementation, the glue spraying nozzle 01 can enter the air suction gap 11 from the first air inlet or the second air inlet, and extends into the air suction cover 1 from the glue spraying opening 114 of the air suction gap 11 to glue the cigarette paper in the air suction cover 1. Generally, the bottom of the air suction hood 1 is provided with an opening communicated with the cigarette paper channel, so that the cigarette paper can pass through the cigarette paper channel and be coated with glue by the glue spraying nozzle 01. The ends of the first air guiding side wall 111 and the second air guiding side wall 112 far away from the bottom wall 113 of the wind screen form a second air inlet opposite to the bottom wall 113 of the wind screen. The distance between the first wind guiding sidewall 111 and the second wind guiding sidewall 112 gradually decreases from the first wind inlet to the glue spraying opening 114.

The second vertical portion is connected to the wind shielding bottom wall 113, and the second vertical portion is perpendicular to the wind shielding bottom wall 113. The second inclined portion 1120 extends in a direction away from the first air guiding sidewall 111. Generally, the angle between the second inclined portion 1120 and the second vertical portion is greater than 90 ° to achieve better flow guiding effect.

The first and second air guiding sidewalls 111 and 112 of this structure are beneficial to effectively guide the external air flow to enter the air suction gap 11, and more external air flow relative to the first air inlet can enter the air suction gap 11 from the second air inlet, thereby improving the stability of the air flow entering the glue spraying opening 114.

Furthermore, a connecting disc 21 is arranged on the air suction chamber 2, and a communication port (not shown in the figure) communicated with the air suction chamber 2 is arranged on the connecting disc 21. The air suction cover 11 is connected with the connecting disc 21 through a rotating shaft 22, and a suction opening of the air suction cover 11 is communicated with the communication opening under the working state of the glue nozzle 01.

Under the working state of the glue nozzle 01, the suction opening of the air suction cover 11 can be connected with the communication opening of the connecting disc 21, so that the air suction cover 11 is communicated with the air suction chamber 2, and suction is generated in the air suction cover 11.
