[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1 In the embodiment of the utility model, a vacuum system for a cigarette packaging machine includes a cyclone separator 1, a buffer tank 2, a cooling system, a conveying system and a vacuum system connected in sequence;

[0019] The cooling system is a washing tower 3; the conveying system is a plurality of conveying pipelines 4; and the vacuum system is a high-efficiency dry screw vacuum pump 5.

[0020] The input end and the output end of the cyclone separator 1 are both provided with a delivery pipeline 4, the input end of the cyclone separator 1 is connected to the gas input structure through the output pipeline, the output end of the cyclone separator 1 is connected to the buffer tank 2 through the delivery pipeline 4, the buffer tank 2 is connected to the washing tower 3 through the delivery pipeline 4, and the washing tower 3 is connected to the high-efficiency dry screw vacuum pump 5 through the delivery pipeline 4;

[0025] When this system processes the gas in the wrapping workshop, the gas extracted from the wrapping workshop first passes through the cyclone separator 1 to initially separate the large particle impurities, and then enters the buffer tank 2 to stabilize the vacuum degree of the system and further separate the particle impurities. The gas coming out of the buffer tank 2 directly enters the washing tower 3 to effectively remove the tiny particles in the gas. Then the clean gas enters the high-efficiency dry screw vacuum pump 5 and is discharged outdoors.
