[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by the person of ordinary skill in the art without making creative labor belong to the scope of protection of the present application. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other at will.

[0022] Reference Figures 1 to 5 The device for sucking off water-based paper of a cigarette making machine provided in the present application comprises a pipe 1, a connecting structure connected with the pipe 1, the pipe 1 can be fixedly connected with the connecting structure or can be detachably connected with the connecting structure, the connecting structure comprises a fixing seat 2 and a sucking structure, the fixing seat 2 is connected with the pipe 1 to realize the connection of the connecting structure with the pipe 1, the sucking structure is connected with the side of the fixing seat 2 away from the pipe 1, and the sucking structure is used for forming a negative pressure on the side of the fixing seat 2 away from the pipe 1. By forming the negative pressure on the side of the fixing seat 2 away from the pipe 1, the air on the side of the fixing seat 2 close to the pipe 1 can be rapidly supplemented to the side of the fixing seat 2 away from the pipe 1. In the process of air supplement, the water-based paper on the inner wall of the pipe 1 can be taken away together, so that the sucking structure can realize the sucking function on the water-based paper on the inner wall of the pipe 1.

[0023] The specific structure of the suction structure includes a connecting base 31 provided with a through hole 32, and a tracheal joint 33 connected with the through hole 32. The end of the tracheal joint 33 away from the through hole 32 is used for introducing compressed air. The way of introducing compressed air can be connecting an air compressor at the end of the tracheal joint 33 away from the through hole 32, so as to introduce compressed air into the tracheal joint 33. The connecting base 31 is connected with the fixed base 2. Meanwhile, a first cylinder 34 is arranged on the inner wall of the side of the connecting base 31 away from the fixed base 2. In addition, a second cylinder 21 is arranged on the side of the fixed base 2 away from the pipeline 1. The inner diameter of the first cylinder 34 is greater than the outer diameter of the second cylinder 21, so as to realize that the first cylinder 34 is sleeved on the second cylinder 21. Meanwhile, an annular gap 41 is formed between the inner wall of the first cylinder 34 and the outer wall of the second cylinder 21. Meanwhile, the first cylinder 34, the inner wall of the side of the connecting base 31 away from the first cylinder 34, and the outer wall of the second cylinder 21 form an annular groove 42. The through hole 32 is connected with the annular groove 42.

[0024] The specific working principle of the suction structure is as follows: compressed air is introduced into the end of the tracheal joint 33 away from the through hole 32. The compressed air enters the annular groove 42 along the tracheal joint 33 and the through hole 32. The compressed air fills the entire annular groove 42. Meanwhile, the annular gap 41 between the first cylinder 34 and the second cylinder 21 can discharge the compressed air in the annular groove 42. Since the pressure of the compressed air in the annular groove 42 is continuously enhanced, the speed of the air discharged from the annular gap 41 is also continuously accelerated. The rapidly discharged air forms a negative pressure at the end of the connecting base 31 away from the fixed base 2, so as to make the air on the side of the fixed base 2 close to the pipeline 1 rapidly supplement to the side of the connecting base 31 away from the fixed base 2. In the process of air supplement, the water-proof paper on the inner wall of the pipeline 1 is also taken away, so as to realize the suction function of the suction structure on the water-proof paper on the inner wall of the pipeline 1.

[0025] The application also includes a positioning base 22. The positioning base 22 is arranged on the side of the fixed base 2 away from the pipeline 1. The positioning base 22 is used for positioning and installing the connecting base 31 on the fixed base 2. The positioning base 22 can facilitate the installation of the connecting base 31 on the fixed base 2, and improve the installation efficiency.

[0026] Preferably, when the connecting base 31 is installed and connected with the fixed base 2, the positioning base 22 is arranged on the inner side of the connecting base 31. The outer diameter of the positioning base 22 is less than the inner diameter of the connecting base 31.

[0027] The compressed air in the annular groove 42 is discharged to the side of the connecting seat 31 away from the fixed seat 2 through the annular gap 41, but due to the gap between the connecting seat 31 and the fixed seat 2, part of the compressed air in the annular groove 42 may be discharged to the outside through the gap, thereby slowing down the speed of the air discharged from the annular gap 41, which is not conducive to the formation of negative pressure at the end of the connecting seat 31 away from the fixed seat 2. Therefore, in order to prevent the compressed air in the annular groove 42 from being discharged to the outside through the gap between the connecting seat 31 and the fixed seat 2, the application also comprises an airtight structure arranged on the fixed seat 2. The airtight structure is arranged to seal the connection between the fixed seat 2 and the connecting seat 31. The airtight structure can be made of a cementing material to seal the connection between the fixed seat 2 and the connecting seat 31.

[0028] Preferably, the airtight structure comprises a sealing ring 51 and a groove 52 arranged on the positioning seat 22. The sealing ring 51 is arranged in the groove 52 and has a pressing effect on the inner wall of the connecting seat 31 when the connecting seat 31 is connected to the fixed seat 2. This arrangement can seal the connection between the fixed seat 2 and the connecting seat 31 to prevent the compressed air in the annular groove 42 from being discharged through the connection between the fixed seat 2 and the connecting seat 31. The sealing ring can be made of polytetrafluoroethylene material, which has good properties such as wear resistance, water resistance, high temperature resistance, corrosion resistance and anti-aging, and is not easy to damage, with a longer service life.

[0029] Since the air inlet rate in the annular groove 42 is greater than the air outlet rate in the annular groove 42, the air pressure in the annular groove 42 will continue to increase. At a certain moment, the air pressure in the annular groove 42 may be greater than the air pressure of the compressed air entering the annular groove 42, so that the compressed air cannot enter the annular groove 42, and even the air compressor may be damaged. To avoid such accidents, the application also comprises a pressure regulating valve 35 arranged on the connecting seat 31. The pressure regulating valve 35 is in communication with the annular groove 42 and can control the pressure in the annular groove 42 to prevent the air pressure in the annular groove 42 from being greater than the air pressure output by the air compressor.

[0030] Threaded holes are arranged on the fixed seat 2 and the connecting seat 31, and the fixed seat 2 and the connecting seat 31 are connected by bolts.

[0031] The above description can be implemented alone or in various combinations, and these variations are within the scope of the present application.

[0032] The orientation terms mentioned or possibly mentioned in the present specification, such as up, down, left, right, front, back, front side, back side, top, bottom, etc., are defined relative to the configuration shown in the drawings, and the words "inner" and "outer" refer to the direction toward or away from the geometric center of a particular component, which are relative concepts, so it is possible to change accordingly according to different positions, different use states. Therefore, these or other orientation terms should not be interpreted as limiting terms.
