    • 2. Description of Related Art
  • Traditionally, tobacco sheet is shredded to have a shape similar to loose tobacco fragments and mixed with loose tobacco fragments before putting into a specialized tobacco rod forming machine to be made into tobacco rods. However, the existing tobacco rod forming machines are not suitable for making continuous, pure, filament-bundle-like, tobacco rods. The existing cigarette filter making machines draw tough acetate fibers or polyacrylic fibers through a strip-guiding horn-shaped mouth and a pipe to bundle the fiber into filters. However, for less tough and fragile rolled tobacco sheet, the existing filter forming machines are not proper processing tools, neither.
  • Recently, a novel form of cigarettes called electric heat-not-burn cigarette have become known in the market. This new type of cigarettes requires its tobacco rod to be made of tobacco strips arranged orderly in a lengthwise direction. Hence, there is a need for refitting an existing cigarette filter forming machine to adapt it to the physical properties of stripped tobacco sheet and thereby making it effective in on-line stripping and gathering tobacco strips into rods with maximized convenience and minimized costs.

    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a schematic drawing of a sheet-striping, strip-gathering, rod-forming mechanism based on a cigarette filter forming machine of the present invention.
    • DETAILED DESCRIPTION OF THE INVENTION
  • Referring to FIG. 1 for the disclosed mechanism. Therein, an active roll release device for tobacco sheet roll 1 is additionally installed behind releasing rollers of the filter forming machine, which has a linear velocity matching a rod-forming linear velocity of the mechanism. A pair of releasing rollers near a pipe is replaced by stripping rollers with interrupted roller pattern along respective circumference. When drawn together, the two rollers cut the tobacco sheet into strips while conveying the stripped tobacco sheet forward. A strip-guiding horn-shaped mouth 14 is replaced by a tapered and collapsed horn-shaped mouth with an inlet diameter of 80-120mm. The active roll release device of the present mechanism includes a servo motor installed on a rotating shaft 2 of the tobacco sheet roll 1, and an ultrasonic detector 3 arranged at an edge of a sheet of sheet roll, in which ports of a single chip microcontroller in a power control cabinet of the filter forming machine are connected to the servo motor, the ultrasonic detector 3 and a tobacco rod detector of the filter forming machine, respectively, so that the single chip microcontroller adjusts an angular velocity of the servo motor, to make the linear velocity of the edge of the sheet match the real-time linear velocity of rod-forming; the interrupted roller pattern 4 of the stripping rollers is arranged at a surface of an upper roller 5, and the interrupted roller pattern 4 and an axis of the stripping roller include an angle of 90-45°. When the angle is 90°, the direction of the tobacco strip bundle is parallel with the moving direction. When the angle is smaller than 90°, the tobacco strip bundle is inclined. The lower roller 6 is a shallow groove or a smooth roller, so as to ensure the tobacco sheet is cut through. The upper stripping roller 5 is almost fully covered by the interrupted roller pattern 4 in its axial direction except that the ends close to shaft are smooth segments 7, which ensures the parts of the tobacco sheet in the segments are not cut, thereby preventing tangles and broken ends at the edges of the sheet. The upper roller 5 is equipped with a separate driving device. One end of the upper roller 5 is provided with a gear 8 at inner edge, working as a driving wheel. The lower roller 6 has its rotating shaft equipped with a hydraulic cylinder 10 acting as a lifting mechanism for allowing vertical adjustment. The lower roller 6 is equipped with a gear 9 that matches the gear 8 of the upper roller 5 at inner edge. When the lower roller 6 is lifted, the gear 9 engages with the gear 8 of the upper roller 5 and is driven to roll together. A buffer area 11 for sheet hanging is located below the sheet of sheet roll, and a photoelectric sensor 12 is installed in the buffer area 11, which is connected to the port of the single chip microcontroller in the power control cabinet, and further feeds back to a servo motor control system of the single chip microcontroller, thereby forming closed-loop control for correcting a cumulative deviation during roll release operation of the servo motor. The strip-guiding horn-shaped mouth 14 is provided with a compressed air inlet 13, so as to remove tobacco dust while guiding strips when then mechanism is in operation. The rotating shaft 2 for the paper sheet roll 1 of the present mechanism is an air shaft. When the sheet roll is mounted in position, the shaft is fixed by air inflation to secure the roll from loosening.
