Description

Technical Field

[0001] This invention belongs to the field of cigarette manufacturing technology, and in particular relates to a novel cigarette shifting device. Background Technology

[0002] The existing method for cigarette closing and shifting in the tobacco industry uses negative pressure adsorption, but it has high requirements for the structure of the tobacco. When the tobacco contains dust, the negative pressure will suck away the dust from the ends of the tobacco, resulting in an empty cigarette head, which affects the quality of the cigarette. In addition, the sucked-away tobacco dust is easy to block the negative pressure hole, causing the negative pressure adsorption force to decrease. As a result, the success rate of cigarette shifting and closing cannot reach 100%, which affects the overall quality of the finished cigarette and increases the loss rate. Summary of the Invention

[0003] As described above, the technical problem to be solved by the present invention is to provide a novel cigarette shifting device, which uses negative pressure to quickly shift the cigarettes adsorbed on the arc groove of the slider body of the moving slider during one revolution of the drum, so as to meet the requirements of downstream processes for the spatial arrangement of cigarettes.

[0004] The present invention specifically adopts the following solution:

[0005] A novel cigarette shifting device includes a gas distribution wall plate, a gas distribution seat, a grooved cam, a movable slider, a drum, and a drive shaft. The gas distribution seat is fixed to the gas distribution wall plate, which provides a negative pressure gas source. The negative pressure gas source is transmitted to the movable slider through the gas distribution seat. The grooved cam is fixed to the gas distribution seat. The drive shaft passes through the center of the gas distribution seat along its axial direction and is rigidly connected to the drum. At least one rolling bearing for support and positioning is provided between the drive shaft and the gas distribution seat. At least two movable sliders are evenly distributed around the circumference of the drum. The drive shaft rotates together with the drum, while the gas distribution wall plate, the gas distribution seat, and the grooved cam remain stationary.

[0006] Furthermore, the movable slider includes a bearing, a connecting rod, and a slider body that move in the groove of the grooved cam. The bearing, connecting rod, and slider body are rigidly fixed as a whole. The slider body is provided with at least one arc groove for passing negative pressure to adsorb cigarettes.

[0007] The drum wheel includes a wheel body and guide slide rods, the number of which is at least twice the number of movable sliders. The wheel body and the guide slide rods are rigidly fixed as one piece. The slider body of the movable slider is constrained along the guide slide rods and moves back and forth under their constraint.

[0008] When the drive shaft rotates the drum, the moving slider moves left and right under the drive of the grooved cam. Because the slider body is provided with a circular arc groove that applies negative pressure to attract cigarettes, the cigarettes attracted by it move closer to the center once during each rotation, thus realizing the function of rapid cigarette movement.

[0009] The groove of the bearing that constrains the moving slider on the grooved cam is at least one three-dimensional annular groove. Attached Figure Description

[0024] Specific embodiments of the present invention

[0025] Example 1: As Figures 1 to 4As shown, this invention provides a novel cigarette shifting device.

[0026] The novel cigarette shifting device mainly includes a gas distribution wall plate 1, a gas distribution seat 2, a grooved cam 3, a moving slider 4, a drum 5, and a drive shaft 6.

[0027] The valve seat 2 is fixed to the valve wall plate 1, which provides a negative pressure air source. The negative pressure air source is transmitted to the movable slider 4 through the valve seat 2. The grooved cam 3 is fixed to the valve seat 2. The drive shaft 6 passes through the center of the valve seat 2 along the axial direction and is rigidly connected to the drum 5. The drive shaft 6 rotates together with the drum 5, while the valve wall plate 1, the valve seat 2, and the grooved cam 3 remain stationary.

[0028] At least one rolling bearing for supporting and positioning is provided between the drive shaft 6 and the valve seat 2. In this embodiment, there are two rolling bearings.

[0029] The drum 5 has at least two movable sliders 4 evenly distributed along its circumference. In this embodiment, the number of movable sliders 4 is four.

[0030] The movable slider 4 mainly includes a bearing 401 that moves in the groove of the grooved cam 3, a connecting rod 402, and a slider body 403, which are rigidly fixed as a whole. The slider body 403 is provided with at least one arc groove for passing negative pressure to adsorb cigarettes.

[0031] The drum 5 mainly includes a wheel body 501 and guide slide rods 502, which are at least twice the number of movable sliders 4. In this embodiment, there are eight guide slide rods 502.

[0032] The wheel body 501 and the guide slide rod 502 are rigidly fixed as one piece. The slider body 403 of the movable slider 4 is constrained along the guide slide rod 502 and moves back and forth under its constraint.

[0033] When the drive shaft 6 rotates the drum 5, the movable slider 4 moves left and right under the drive of the grooved cam 3. Because the slider body 403 is provided with an arc groove for adsorbing cigarettes by applying negative pressure, the cigarettes adsorbed by it move closer to the center once during each rotation, thereby realizing the function of rapid cigarette displacement. This embodiment Figure 1 The process of moving the cigarette is as follows: the cigarette being moved comes from the upper right position and is attracted to the arc groove of the slider body 403. The drum 5 rotates counterclockwise, and the slider body 403 moves the cigarette to the lower left position.

[0034] The groove of the bearing 401 that constrains the movable slider 4 on the grooved cam 3 is at least one three-dimensional annular groove. In this embodiment, the number of three-dimensional annular grooves is one.

[0035] During the rotation of the drum 5, the negative pressure is used to quickly move the cigarettes adsorbed on the arc groove of the slider body 403 of the movable slider 4 to meet the requirements of the downstream process for the spatial arrangement of the cigarettes.

[0036] The above-described embodiments are preferred embodiments of the present invention and are only used to facilitate the illustration of the present invention. They are not intended to limit the present invention in any way. Any equivalent embodiments made by those skilled in the art without departing from the technical features of the present invention, using the technical content disclosed in the present invention, and without departing from the technical features of the present invention, shall still fall within the scope of the technical features of the present invention.
