The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0014] As Figures 1-5As shown, a cigarette rod separating device, its housing 1 is installed on the shaft 2, the fixed shaft sleeve seat 3 is sleeved on the shaft 2 in the housing 1. Specifically, the shaft 2 is installed in the fixed shaft sleeve seat 3 through the end bearing 3-1 at both ends, the right end surface of the fixed shaft sleeve seat 3 is fixed on the outer connecting piece 15 through the screw, so the fixed shaft sleeve seat 3 is fixed. The end cover on the left side of the housing 1 is fixed on the left end of the shaft 2, and the end cover on the right side of the housing 1 is installed on the right end of the fixed shaft sleeve seat 3 through the bearing, so the housing 1 can rotate with the shaft 2.

[0015] The side surface of the above-mentioned housing 1 is arranged with a slide groove group at equal intervals, each slide groove group is composed of two collinear and opposite slide grooves 1-1, and a guide rail group is fixed in the housing 1 with the axis of the shaft 2 as the central axis, each guide rail group corresponds to each slide groove group, and each guide rail group is composed of two parallel guide rails 1-2.

[0016] Two sliders 9 are installed on each guide rail group, each slider 9 is fixed with a suction disc 10 after penetrating the slide groove 1-1, a joint bearing 8 is fixed at the bottom of each slider 9, and a stud 7 is fixed at one end of the joint bearing 8 and at one end of the outer movable ring 5. Two parallel arc-shaped suction grooves 10-1 are provided on the suction disc 10, which are matched with the side curved surface of the cigarette rod, and negative pressure holes 10-2 are arranged on each suction groove 10-1. Each negative pressure hole 10-2 is connected to a centralized negative pressure system through a pipeline, which provides a negative pressure source for the cigarette production line. Therefore, under the action of the above-mentioned negative pressure hole 10-2, each suction groove 10-1 can firmly adsorb the cigarette rod.

[0017] The two inner movable rings 4 on both ends of the fixed shaft sleeve seat 3 are inclined and symmetrical, and on the opposite inner side surface of each inner movable ring 4, one side is connected and fixed with the fixed shaft sleeve seat 3 through the support hinge 11, and the opposite side is provided with the adjusting hinge 12. The screw rod fixing seat 14 is fixed on the fixed shaft sleeve seat 3, and the adjusting screw rod 13 penetrates the screw rod fixing seat 14 and the two ends of the adjusting screw rod 13 are threadedly connected with the adjusting hinge 12. Specifically, the support hinge 11 includes a support 11-1, one end of which is fixed on the inner movable ring 4, and the other end is hingedly connected to the upper part of the connecting plate 11-2, the bottom of which is fixed on the fixed shaft sleeve seat 3; the adjusting hinge 12 includes a support plate 12-1, one end of which is fixed on the inner movable ring 4, and the other end is hingedly connected to the adjusting plate 12-2, which is provided with a threaded hole, and the threaded end of the end of the adjusting screw rod 13 is connected with the threaded hole.
