Cigarette making machine tobacco suction device forming air chamber device and loose-end cigarette and bamboo cigarette defect control method

Abstract

The invention provides a cigarette making machine tobacco suction device forming air chamber device. The cigarette making machine tobacco suction device forming air chamber device comprises a lower air injection chamber and an air inlet assembly conveying positive pressure air to the lower air injection chamber. The lower air injection chamber comprises a box body limiting a circulating cavity, a first air inlet and a second inlet which are symmetric about the symmetric axis of the box body are formed in the bottom of the box body, the box body is provided with an air blowing opening communicating with the circulating cavity, the air blowing opening extends to the right side of the box body from the left side of the box body, an air guide plate is arranged at the air blowing opening, and annular arc-shaped grooves uniformly distributed are formed in the guide plate. The air inlet assembly comprises a first air inlet connector, a second air inlet connector, a three-way pipe, a first ventilating pipeline and a second ventilating pipeline, the first ventilating pipeline is connected with the first inlet through the first air inlet connector, the second ventilating pipeline is connected with the second air inlet through the second air inlet connector. The three-way pipe is provided with two bifurcated pipes communicating with each other and a main pipe, the two bifurcated pipes are separately connected with the first ventilating pipeline and the second ventilating pipeline, and positive pressure air flow flows to the two bifurcated pipes through the main pipe.

Description

technical field [0001] The invention belongs to the field of thread suction forming of a YJ17D type (fine count) cigarette machine, and in particular relates to an air chamber device for suction forming of a cigarette machine, which can be widely used in the production of thin cigarettes by a ZJ17D type (fine count) coiling machine. The device realizes that the airflow ejected from the lower air injection chamber is consistent before and after, so that the cut tobacco is uniform before and after the suction forming process, and finally the quality of the slim cigarette product is stable. The effect is remarkable. Background technique [0002] In the existing tobacco industry, the suction and forming air chambers of tobacco cigarette machines supply air on one side, and the airflow ejected from the lower and lower air injection chambers has a great influence on the shredded tobacco thrown by the throwing rollers, which is uneven and unstable, especially for thin cigarettes in...

Problems solved by technology

[0002] In the existing tobacco industry, the suction and forming air chambers of tobacco cigarette machines supply air on one side, and the airflow ejected from the lower and lower air injection chambers has a great influence on the shredded tobacco thrown by the throwing rollers, which is uneven and unstable, especially for thin cigarettes in the industry. The production of thin cigarettes caused the quality of thin cigarettes to be unstable, and the quality defects such as short cigarettes and bamboo cigarettes were obviously too high, and the consumption was too large. The bamboo cigarettes caused continuous shutdown of the equipment, which greatly reduced the efficiency of the equipment
