as shown in fig. 3 and 4, the elbow 4 is configured to be mounted on a wall plate 19 provided on the shredded tobacco conveying strip 16; the second end of the first gas pipe 6 is connected with the first end of the tee joint 7 through another threaded joint 5; the second end of the tee joint 7 is connected with the first end of the control valve 9, and the second end of the control valve 9 is connected with the negative pressure pipeline 20; the second end of the tee joint 7 is connected with the first end of the pressure regulating valve 13 through the second air pipe 12; the second end of the pressure regulating valve 13 is connected with the first end of the three-way quick connector 15 through the third air pipe 14; the second end of the three-way quick connector 15 is connected with the positive pressure air source 21.
Compared with the prior art, the cleaning device for the accumulated dust in the tobacco shred conveyor belt can prevent and treat the accumulated dust in the tobacco shred conveyor belt assembly under the condition that the tobacco shred conveyor belt assembly is not disassembled, so that the inside of the tobacco shred conveyor belt assembly is kept in a clean state. The labor and time cost during maintenance are saved, and the maintenance efficiency is improved. In addition, the cleaning device for the dust accumulation in the tobacco shred conveyor belt can also realize a certain degree of self-cleaning function, and is more convenient to use.
Specifically, the cleaning device for the dust accumulation in the tobacco shred conveyor belt 16 provided in the embodiment is suitable for cleaning the dust accumulation in the tobacco shred conveyor belt 16 assembly of the PROTOS70 cigarette making machine.
More specifically, the positive pressure air source 21 and the negative pressure pipeline 20 are equivalent to introducing two air sources for the device; as an alternative embodiment, the positive pressure air source 21 may be a driving air source lowered by an SE electric soldering iron, and the pressure may be up to 5bar; the negative pressure pipeline 20 is connected with a negative pressure air source of the central negative pressure pipeline 20, and the pressure is 11000pa to 12000pa. Thus, the negative pressure conduit 20 may be normally open, while the positive pressure air source 21 is controlled by the solenoid valve of the SE electric soldering iron: the cigarette making machine is switched on when running, and is switched off when stopping or waiting. The working principle of the cleaning device for the dust accumulation in the tobacco shred conveyor belt 16 provided by the embodiment is as follows:
when the cigarette making machine operates, a driving air source for lowering the SE electric iron is connected, compressed air provided by the positive pressure air source 21 enters the tee joint 7 after being regulated by the pressure regulating valve 13 through the three-way quick connector 15, the second air pipe 12 and the third air pipe 14, at the moment, part of the compressed air provided by the positive pressure air source 21 can counteract negative pressure induced draft of the negative pressure pipeline 20, and the rest of the compressed air enters the dust removing pipe 1 along the first air pipe 6 and enters the tobacco shred conveying belt 16 assembly from a dust removing hole of the dust removing pipe 1, so that the air pressure in the tobacco shred conveying belt 16 assembly is slightly higher than that in the outside, and the positive pressure air overflows outwards from a gap of the tobacco shred conveying belt 16 assembly to block smoke dust from entering the tobacco shred conveying belt 16 assembly.
When the cigarette making machine is stopped or standby, the electromagnetic valve of the SE electric soldering iron acts, at the moment, the driving air source of the electric soldering iron is cut off, compressed air entering the device is also cut off, at the moment, negative pressure at the tee joint 7 is not counteracted any more, and negative pressure forms negative pressure air suction at the exhaust hole of the dust removal pipe 1 along the first air pipe 6. Since the shredded tobacco transport belt 16 is still rotating at high speed when the cigarette machine is stopped or standby, smoke dust inside the assembly, which was previously not blocked by the positive pressure, is lifted, and the lifted smoke dust is sucked by the small holes of the dust removing pipe 1.
When the cigarette making machine is started to run again, the compressed air provided by the positive pressure air source 21 flows through the dust removing pipe 1 again, and floating dust attached to the inner wall of the dust removing pipe 1 is removed, so that a certain degree of self-cleaning function is realized.
More specifically, when the dust removing pipe 1 is installed inside the tobacco shred conveying belt 16 assembly, holes are required to be drilled and installed at corresponding positions on the bracket 18, the side plates 17 and the wall plates 19 of the tobacco shred conveying belt 16 assembly, the two side plates 17 can axially fix the dust removing pipe 1, the side plates 17 are provided with holes at positions corresponding to the dust removing pipe 1, the aperture is equal to the inner diameter of the dust removing pipe, so that air flow can pass through and the dust removing pipe 1 can be positioned. There may be a gap between the dust removing pipe 1 and the side plate 17, and in order to avoid leakage of air flow, a sealing ring is installed around the dust removing pipe 1 between the side plate 17 and the bracket 18. To allow the air flow to pass through the machine wall 19, holes are formed and tapped in the wall 19 at positions corresponding to the positions of the dust removal pipe 1, for installing the elbow 4, and a 16 x 1/2 nipple 5 is connected to the elbow 4.
