As shown in figures 1 to 3, the safety control device for the protective door of the cigarette making machine disclosed by the utility model comprises a protective door slide rail, a pushing mechanism and a transmission mechanism.
The protective door slide rail 1 is provided with a chute 101 which is in sliding fit with the protective door of the cigarette making machine. The wall of chute 101 is provided with pusher aperture 102. The edge of the protective door of the cigarette making machine can move in the sliding groove 101 of the protective door sliding rail 1. As the cigarette machine guard door slides through the pusher aperture 102, a force may be applied to the ejector 201 of the pusher 2 protruding out of the pusher aperture 102.
The pushing mechanism comprises a pushing piece 2 and a reset assembly. The pushing piece 2 is provided with an ejecting part 201 and an engaging part 202. The ejector 201 is matched with the pushing member hole 102, and the matching between the ejector and the pushing member hole can be sliding fit or clearance fit. The ejector 201 may have an arcuate surface to more smoothly contact the cigarette maker guard door. The engaging portion 202 is provided with engaging teeth. In specific implementation, the meshing teeth can be arranged into a strip-shaped structure. The reset assembly includes a reset member 3, the reset member 3 operable to provide a force to the pusher member 2 toward the pusher member bore 102. The restoring member 3 may be a spring or a spring plate, for example. In specific implementation, the pushing element 2 and the resetting element 3 can be arranged on the protective door sliding rail 1 or on some parts of the cigarette making machine.
The transmission mechanism comprises a transmission gear assembly and a clutch assembly. The transmission gear assembly comprises at least two transmission gears. The number of the transmission gears can be flexibly set according to actual requirements. The clutch assembly comprises a sliding part 6 and a clutch gear 7, and the sliding part 6 is provided with a matching part 600. The fitting portion 600 may have a rack-like structure. A transmission gear assembly is located between the engaging portion 202 and the mating portion 600 to transmit the movement of the pusher member 2 to the slider 6. The clutch gear 7 is rotationally connected to the slider 6, so that the clutch gear 7 can be moved rotationally relative to the slider 6. Through the transmission action of the transmission gear component, the pushing piece 2 can drive the sliding piece 6 to move, and thus, the clutch gear 7 can also move along with the sliding piece 6. In practice, the sliding member 6 may be slidably mounted on the guard door slide rail 1, or on some component of the cigarette making machine. The movement of the slide 6 may be generally linear.
The clutch gear 7 has an interlocking state and a disengaged state.
In the linkage state, the clutch gear 7 is meshed with the motor gear 01 and the power wheel 02 of the cigarette making machine to transmit the driving force of the motor gear 01 to the power wheel 02. The linkage state of the clutch gear 7 is the state when the protective door of the cigarette making machine is not opened. In this state, the protective door of the cigarette making machine is not opened, the cigarette making machine normally works, and the driving force of the electric gear 01 is transmitted to the power wheel through the clutch gear 7.
In the disengaged state, the clutch gear 7 is separated from the motor gear 01 and the power wheel 02 of the cigarette making machine to disconnect the power transmission between the motor gear 01 and the power wheel 02. The linkage state of the clutch gear 7 is the state when the protective door of the cigarette making machine is opened. In this state, the protective door of the cigarette making machine is opened, the clutch gear 7, the motor gear 01 and the power wheel 02 are all separated, and the driving force of the electric gear 01 cannot be transmitted to the power wheel 02 through the clutch gear 7.
The safety control device for the protective door of the cigarette making machine can be used as follows in the using process:
when the cigarette machine protective door is opened, the cigarette machine protective door moves in the sliding groove 101 of the protective door sliding rail 1, and the ejection part 201 of the push piece 2 protruding out of the push piece hole 102 moves towards the direction far away from the protective door sliding rail 1 under the extrusion of the cigarette machine protective door. Along with the movement of the pushing piece 2, the meshing part 202 of the pushing piece 2 drives the transmission gear assembly to rotate, and the sliding piece 6 meshed and matched with the transmission gear assembly drives the clutch gear 7 to move in the direction of separating from the motor gear 01 and the power wheel 02. The direction in which the clutch gear 7 is separated from the motor gear 01 and the power wheel 02 may be, for example, a direction away from the protective door sliding rail 1. When the clutch gear 7 is driven by the sliding part 6 to move to be separated from the motor gear 01 and the power wheel 02, the power of the motor cannot be transmitted to the power wheel 02, so that the cigarette making machine stops working.
When the protective door of the cigarette making machine is closed, the pushing piece 2 is not extruded by the protective door of the cigarette making machine any more. The pushing member 2 moves toward the pushing member hole 102 by the reset member 3. Along with the movement of the pushing piece 2, the meshing part 202 of the pushing piece 2 drives the transmission gear assembly to rotate, and the sliding piece 6 meshed and matched with the transmission gear assembly drives the clutch gear 7 to move towards the direction meshed and matched with the motor gear 01 and the power wheel 02. The direction in which the clutch gear 7 is engaged with the motor gear 01 and the power wheel 02 may be, for example, a direction close to the protective door sliding rail 1. When the clutch gear 7 is driven by the sliding part 6 to move to enter between the motor gear 01 and the power wheel 02 and be meshed and matched with the motor gear 01 and the power wheel 02, the power of the motor is transmitted to the power wheel 02, and the cigarette making machine can continue to work.
The pushing piece 2 of the safety control device for the cigarette machine protective door can move towards the direction far away from the protective door sliding rail 1 under the extrusion of the protective door when the cigarette machine protective door is opened, so that the clutch gear 7 leaves the motor gear 01 and the power wheel 02 under the matching of the pushing mechanism and the transmission mechanism, the purpose of power transmission of a cigarette machine when the cigarette machine protective door is opened is achieved, the cigarette machine is prevented from still working when the cigarette machine protective door is opened, and the safety of the cigarette machine protective door can be effectively improved.
