[0031] Referring to Figures 1-4 The embodiment provides a leakage-proof back silk device for a cigarette making machine, which comprises a leakage-proof back silk guide frame 1 and a leakage-proof back silk conveying pipe 7.
[0032] A first driving member is arranged on the outer side of the leakage-proof back silk guide frame 1, and the first driving member is a driving motor 2. The output end of the driving motor 2 is connected with a rotating rod 3 through a spline. The outer surface of the rotating rod 3 is fixedly and uniformly provided with a plurality of rubber rods 4. The rotating rod 3 is arranged in the bottom of the leakage-proof back silk guide frame 1, so that the rubber rods 4 are located in the leakage-proof back silk guide frame 1.
[0033] The input end of the leakage-proof back silk conveying pipe 7 is provided with a back silk feeding port 6 with an upward opening. The output end of the leakage-proof back silk conveying pipe 7 is provided with a back silk discharging port 18 with a downward opening.
[0034] The bottom end of the leakage-proof cut tobacco guide frame 1 is fixedly connected with a cut tobacco installation pipe 5 and a cut tobacco feeding port 6. The leakage-proof cut tobacco guide frame 1 is installed below a leveler device collecting groove in a cigarette making machine. A driving motor 2 is started to drive the driving motor 2 to rotate, drive the rotating rod 3 to rotate, and drive the rubber rod 4 to rotate, so that the cut tobacco can be smoothly conveyed to the leakage-proof cut tobacco conveying pipe 7 below. The leakage-proof cut tobacco guide frame 1 and the leakage-proof cut tobacco conveying pipe 7 form a cut tobacco cavity, thereby reducing cut tobacco leakage.
[0035] One end of the leakage-proof cut tobacco conveying pipe 7 is connected with a second driving member, which is a servo motor 8. The output end of the servo motor 8 is connected with a spiral conveying rod 9 through a spline. The servo motor 8 is rotated to drive the spiral conveying rod 9 to rotate, so that the cut tobacco is conveyed from the cut tobacco feeding port 6 to a cut tobacco discharging port 18.
[0036] Four groups of support rod assemblies are connected below the leakage-proof cut tobacco conveying pipe 7. Each group of support rod assemblies comprises a support leg 13, a mounting seat 14, a buffer spring 11 and a damping hydraulic rod 12. The top end of the damping hydraulic rod 12 is fixedly connected with a fixed plate at the bottom of the leakage-proof cut tobacco conveying pipe 7 through a bolt, and the bottom end is movably connected with the support leg 13, allowing the support leg 13 to move in the vertical direction. The buffer spring 11 is sleeved on the outer surface of the damping hydraulic rod 12, and the upper end is in contact with the fixed plate, and the lower end is in contact with the top end of the support leg 13. The buffer spring 11 has elasticity and can store elastic potential energy. The damping hydraulic rod 12 reduces the shock caused by the cigarette making machine and the like, thereby increasing the stability of the leakage-proof cut tobacco device. The bottom end of the support leg 13 is fixedly connected with the mounting seat 14. The surface of the mounting seat 14 is provided with a mounting hole. The support leg 13 supports the leakage-proof cut tobacco conveying pipe 7. The mounting seat 14 installs the leakage-proof cut tobacco conveying pipe 7 on the cigarette making machine through the mounting hole.
[0037] A dust removal port is formed on the top surface of the leakage-proof cut tobacco conveying pipe 7. A filter fine mesh 10 is arranged in the dust removal port. A centrifugal fan body 15 is fixedly installed on the top surface of the leakage-proof cut tobacco conveying pipe 7. The centrifugal fan body 15 is connected with a connecting pipe 16. The other end of the connecting pipe 16 is fixedly connected with a dust suction cover 17. The dust suction cover 17 is arranged above the dust removal port. When the leakage-proof cut tobacco conveying pipe 7 needs to be cleaned, the centrifugal fan body 15 is started. The dust enters the connecting pipe 16 through the filter fine mesh 10, thereby cleaning the leakage-proof cut tobacco conveying pipe 7.
[0038] The above describes the specific embodiments of the utility model in combination with the drawings, but is not a limitation on the protection scope of the utility model.
