Description

Cigarette making and tipping machine filter tip feed system filter stick cutting drum wheel
Technical field
The utility model relates to a kind of filter stick cutting drum wheel, and specifically a kind of cigarette making and tipping machine filter tip feed system filter stick cutting drum wheel, belongs to tobacco machine apparatus field.
Background technology
PROTOS70 cigarette making and tipping machine is main force's type of China's tobacco business production of cigarettes at present, the filter tip feed system of this type is mainly comprised of parts such as filter tip hopper, stirring rod, filter stick cutting drum wheel, dislocation drum, parallel drum-wheel, accelerating drums, its function is that multiple length filter stick material is cut to long three sections of isometric double-length filter tip heads, and by them and do single file output.
During filter stick cutting drum wheel duty, after falling, the multiple length filter stick material getting off in upstream is attracted on filter stick cutting drum wheel negative pressure region, filter stick cutting drum wheel is rotated further, during through cutting blade, filter stick material is divided into three sections, during finally by excessively isolated negative pressure region, three sections of filter sticks that have been cut fall, and the wheel hub that misplaced adsorbs.
As shown in Figure 1, existing filter stick cutting drum wheel generally comprises air inlet disk 11, gas distribution plate 12, wheel body 2, core wheel 13 and locking end cap 3, and air inlet disk 11 is fixedly installed in main frame wallboard 4, and air inlet disk 11 is provided with negative pressure ventilation hole and communicates with the negative pressure system on main frame; Gas distribution plate 12 is fixedly connected with wheel body 2, and wheel body 2 is fixedly connected with core wheel 13, on gas distribution plate 12 end faces, is along the circumferential direction provided with uniform through hole; Wheel body 13 is Split type structures, comprise three identical torus groups, torus group surface is provided with uniform profile of tooth groove, and profile of tooth bottom portion of groove is provided with passage, the through hole correspondence position of torus group end face and gas distribution plate 12 is provided with negative-pressure air-suction passage, and axial negative pressure channel is communicated with passage radially; Locking end cap 3 is fixedly connected on core wheel 13 and is fixedly connected with driving sleeve 7.
During duty, main shaft 5 is fixed, travelling gear 6 drives driving sleeve 7 rotations, driving sleeve 7 ends are fixedly connected with wheel body 2 by locking end cap 3, wheel body 2 drives gas distribution plate 12 rotations simultaneously, and while passing through the negative pressure ventilation hole on air inlet disk 11, the negative-pressure air-suction passage in wheel body 2 is communicated with negative pressure system, wheel body 2 respective surfaces regions produce negative pressure by passage, the filter stick material that absorption upstream falls.
There is following shortcoming in this traditional cutting drum wheel structure:
1. because this mechanism utilizes negative pressure ventilation hole uniform on the negative pressure mouth of air inlet disk 11 and gas distribution plate 12 to form negative pressure filter stick is adsorbed in race, through hole staggered easily makes to aspirate air channel and narrows down, negative regulation is poor, absorption affinity is not strong, there will be the phenomenon that lacks material or squeeze filter tip at stirring rod place during wheel hub feeding; Because the negative-pressure adsorption power in groove is not strong, also exist filter stick that the uneven phenomenons such as hair stubble shape that are of filter segment otch occur when cutting, affect the quality after filter tip cutting;
2. because wheel body 2 is Split type structures, and must guarantee same phase place while installing, therefore centering more complicated is installed;
3. in long-term production run process, the tow foam producing because of filter tip cutting very easily stops up the aperture on disk body and cutting gap, cause air draught unstable, due to malleation blowing passage not being set, therefore the necessary periodic cleaning of filter tip feed system, generally each season need to be disassembled cleaning once, and system maintenance is shorter maintenance period, and single system service time is longer.
