[0022] As Figures 1-3 shown, it relates to a transmission device of cigarette making machine suction tape, including vertical plate 1, first driven wheel 3, two guide wheels 4 and second driven wheel 5, vertical plate 1 surface rotationally connected with driving wheel 2, two guide wheels 4 are located close to driving wheel 2 side, second driven wheel 5 is located between two guide wheels 4, and the height of second driven wheel 5 is lower than that of two guide wheels 4, driving wheel 2, first driven wheel 3, two guide wheels 4 and second driven wheel 5 surface are commonly sleeved with suction tape 6, the top of vertical plate 1 is fixed with horizontal plate 7, and the middle part of horizontal plate 7 is installed with extrusion assembly 8 extruding suction tape 6, and the bottom surface of vertical plate 1 is installed with tension adjusting assembly 9 and PLC controller 10.

[0023] Wherein PLC controller 10 is the commonly used controller on the market, and the tension adjusting assembly 9 can be automatically operated by PLC controller 10.

[0024] The motor 11 is fixed on the surface of the vertical plate 1 and away from the driving wheel 2, and the driving end of the motor 11 is fixedly connected with the driving wheel 2. After the driving wheel 2 is driven to rotate by the motor 11, the driving wheel 2 will drive the silk suction belt 6 to rotate under the action of friction, and the first driven wheel 3, the second driven wheel 5 and the two guide wheels 4 play a guiding and supporting role on the rotation of the silk suction belt 6.

[0026] Since the friction of the silk suction belt 6 sleeved on the surface of the driving wheel 2 is not enough to ensure that the silk suction belt 6 does not slip completely, during use, the first wheel frame 82 can be driven to descend by rotating the screw rod 81, so that the extrusion wheel 83 presses the silk suction belt 6 tightly on the surface of the driving wheel 2, thereby increasing the friction between the silk suction belt 6 and the driving wheel 2, so that even if the silk suction belt 6 is worn out, the phenomenon of slipping will not occur. A knob is fixedly installed at the top end of the screw rod 81 to facilitate the rotation of the screw rod 81.
