Description
Technical Field
The utility model belongs to the technical field of cigarette processing, and particularly relates to a thin rod sliding type nondestructive transmission device.
Background
In the prior art, a conventional online cigarette laser puncher drives a cigarette to run by using a rotary drum, when the cigarette reaches a punching position, the cigarette poking roller runs opposite to the rotary drum, and the cigarette is stripped from a cigarette groove, so that the cigarette can be rubbed, and the drum surface rolls for 360 degrees to realize uniform punching of pulse light beams on the circumference of a rotary cigarette filter tip. The mechanical shifting mode is adopted in the scheme, and the cigarette shifting rotating wheel and the drum wheel are in direct contact with the cigarettes, so that the cigarettes often have appearance distortion, tipping paper warping, empty cigarette ends, cut tobacco falling and the like.
The patent (CN 103600981A) of the inventor discloses a method for perforating by utilizing an independently-driven rotary suction claw, wherein a drum groove adsorbs and drives a cigarette to run, when the cigarette reaches a perforating position, the drum transmits the cigarette to the rotary suction claw, the suction claw adsorbs the cigarette to enable the cigarette to rotate around a central shaft, and the mechanical phase locking is utilized to realize the cigarette transmission.
The patent application (CN 111468843A) of the inventor discloses a thin rod swing arm type transmission device and a matched laser perforating machine thereof, the proposal discloses an improved swing arm proposal, a rotary suction nozzle groove in a chute at the end part of a drum swing arm adsorbs and drives a cigarette to run, when the cigarette reaches a perforating position, an eccentric small shaft is utilized to drive a large arm to swing, and simultaneously, the rotary suction nozzle can slide up and down in the chute at the end part of the swing arm so as to ensure that the space position of the cigarette is static and the relative height of a perforating focusing device is constant. Although the scheme principle is feasible, the rotary suction nozzle device is exposed in the space when sliding in the sliding groove at the end part of the swing arm, dust is easy to form to cause unsmooth sliding, so that the focal length fluctuates and fails when punching.
Chinese patent (CN 1154219 a) discloses a method for perforating by using a cigarette transmission drum, a rotary suction nozzle slot located at the end of a swing arm of the drum to adsorb and drive a cigarette to run, when the cigarette reaches a perforating position, a transmission device located inside the drum drives the swing arm of the cigarette and the suction nozzle to swing against the running direction of the drum, so that the cigarette can keep a relatively stable static state with a perforating focusing device during 360 ° rotation of the cigarette to realize perforation, after perforation, the swing arm returns to an initial position, and drives the suction nozzle to return to an initial angle, thereby completing the handover with an input/output device. However, since the swing axis of the swing arm does not overlap with the rotation center of the drum, when the cigarette sucked by the cigarette suction nozzle at the top end of the swing arm swings back, the spatial position of the cigarette changes, and the distance between the cigarette and the punching focusing device changes, that is, the focal length of the laser changes. While when laser drilling works, the distance changes to make the focusing point defocused and unfavorable for the stability of perforation, although the patent scheme also describes that the suction nozzle rotating shaft is adopted as a crank shaft, namely an eccentric shaft is adopted, and the fluctuation of the eccentric shaft opposite to the eccentric of the swing arm is utilized to offset the change of a part of cigarette distance, so that the scheme makes the structure complex, the fluctuation of the cigarette focal length is unsatisfactory, the stability is poor, and a large number of transmission devices are arranged in the drum, so that the design, the processing and the assembly are inconvenient, and the maintenance is inconvenient.
According to the technical scheme, when the drum groove or the suction nozzle is used for adsorbing cigarettes and the cigarettes reach the punching position, the rotating wheel is used for directly driving the cigarettes to rotate (risks and possibility of damage to the cigarettes), or the backswing with the end chute swing arm is used for driving the suction nozzle to rotate so that the end sliding groove is exposed (maintenance is inconvenient and precision is low), and the change of the rotation axis of the cigarettes is caused to change the focal length (defocusing punching).

The thin rod sliding type nondestructive transmission device comprises a central shaft, a cam, a drum-shaped rotating wheel and a sliding device, wherein the cam, the drum-shaped rotating wheel and the sliding device are coaxially arranged, the rotary suction nozzle device is rotatably arranged on the sliding device, the central shaft is in transmission connection with the rotary force output device, the drum-shaped rotating wheel is in transmission connection with the central shaft, the thin rod is adsorbed in an arc-shaped groove of the rotary suction nozzle device, the thin rod is driven by the drum-shaped rotating wheel to move along the circumference along with the sliding device, the sliding device is distributed on the circumferential end surfaces at the two ends of the central shaft of the drum-shaped rotating wheel in a bilateral symmetry manner, the thin rod is composed of a sliding bracket, a connecting frame, a positioning chute, a crank arm and the cam,
the cam is sleeved on the central shaft and fixed with the frame and does not rotate along with the rotation of the central shaft,
the crank arm end shaft of the sliding device runs along the cam to drive the sliding device to concentrically slide back along the arc of the positioning chute and return, and drive the rotation and the angle return of the rotary suction nozzle device, so that the thin rod is indirectly driven to rotate;
the suction section of the rotary suction nozzle device is provided with a negative pressure arc-shaped groove for sucking the thin rod, and the negative pressure suction hole is connected with a negative pressure source through a partial hollow channel of the rotary shaft;
the sliding devices are uniformly and symmetrically distributed on the circumferential end surfaces at two ends of the central shaft of the drum-shaped rotating wheel, the left sliding device and the right sliding device are fixedly and symmetrically connected through the connecting bracket, the sliding device mainly comprises a sliding bracket, a connecting bracket, a positioning sliding chute, a sector gear and a cam, the cam is coaxially arranged with the central shaft and sleeved on the central shaft and is fixed with the frame, the sector gear is rotationally fixed on the end surface of the drum-shaped wheel through a fulcrum shaft, the tooth surface of the sector gear is meshed with a first transmission tooth of the rotary suction nozzle device to form a first transmission pair, and a second transmission tooth of the coaxial rotary suction nozzle device is meshed with a third transmission tooth coaxially arranged with the drum-shaped wheel to form a second transmission pair, so that the sliding device is driven to slide in the positioning sliding chute to drive the suction nozzle to rotate; the end shaft at the end part of the crank arm of the sector gear runs along the cam to drive the swing of the crank arm to drive the swing back and return of the sliding device.
