As shown in fig. 1, the novel guide wheel mechanism for wing plates of cigarette making machines provided by the embodiments of the present application is installed on a wing plate 100, and is used for guiding cut tobacco, and the wing plate 100 is provided with an installation hole; the guide wheel mechanism of the novel cigarette machine wing plate 100 comprises an inner shaft 200, an outer shaft 300 and a bearing 400; a first end of the inner shaft 200 is fixedly embedded in the mounting hole; the outer shaft 300 is fixedly sleeved on the second end of the inner shaft 200; the bearing 400 is fixedly sleeved on the outer shaft 300, and a gap is formed between one side of the bearing 400 close to the wing plate 100 and the wing plate 100. In the embodiment of the present invention, by fixing the inner shaft 200 to the wing plate 100 and fixing the bearing 400 to the inner shaft 200 through the outer shaft 300, the bearing 400 does not directly contact with the wing plate 100 during the rotation process, and the influence of the high-speed rotation of the bearing 400 on the wing plate 100 can be reduced through the conduction of the outer shaft 300 and the inner shaft 200. Furthermore, since a gap is formed between the bearing 400 and the wing plate 100, heat generated by the high-speed rotation of the bearing 400 is not directly transferred to the wing plate 100, and thus, the heat generation of the wing plate 100 can be prevented. Therefore, the guide wheel mechanism of the wing plate 100 of the cigarette making machine can prevent the wing plate 100 from directly bearing the vibration and heating of the bearing 400 during high-speed operation, and prolong the service life of the wing plate 100.

The size of the gap may be between 5 mm and 10 mm, for example, the size of the gap is 5 mm, 5.5 mm, 6 mm, 7 mm, 7.7 mm, 8 mm, 9 mm or 10 mm, and so on, thereby preventing heat generated by the high-speed rotation of the bearing 400 from being transferred to the wing plate 100 and preventing the gap from being too large, which results in an excessive size of the entire apparatus.

In one embodiment, the axis b of the outer shaft 300 is not coincident with the axis a of the inner shaft 200. Those skilled in the art will appreciate that there are a variety of cigarette types, such as thick cigarettes, thin cigarettes, etc. And the tobacco shreds with different brands are different in the rolling process. Therefore, for cigarettes with different grades of cut tobacco, the installation height of the bearing 400 in the guide wheel mechanism of the novel cigarette making machine wing plate 100 also needs to be adjusted to ensure the proper cut tobacco supply amount. In the embodiment of the application, because the axial lead of outer axle 300 does not coincide with the axial linearity of interior axle 200, the eccentric shaft is constituteed to outer axle 300 and interior axle 200 in the embodiment of the application also, consequently, can be through the angle of axle 200 in the mounting hole in the rotation, thereby can carry out the altitude mixture control to outer axle 300, and bearing 400 is fixed on outer axle 300, realized the regulation to bearing 400 height promptly, so can deal with the production demand of different model tobacco shreds, reduce the empty head rate of finished product cigarette, improve product quality greatly, improve the adaptability of tobacco shred machine to different trade marks.

In one embodiment, the side of the outer shaft 300 remote from the wing plate 100 is chamfered. It will be appreciated by those skilled in the art that the bearing 400 needs to be secured to the outer shaft 300 by an interference fit, and that the outer shaft 300 is chamfered on the side thereof remote from the wing plate 100 to facilitate the installation of the bearing 400. It will also be understood by those skilled in the art that chamfers may also be provided at one side of the outer shaft 300 adjacent to the wing plate 100, or at both sides of the outer shaft 300. Specifically, those skilled in the art can set the setting as needed.

In one embodiment, the length of the outer shaft 300 in the axial direction is equal to the length of the bearing 400 in the axial direction. Since the bearing 400 has a gap with the wing plate 100 and the bearing 400 is interference-fitted with the outer shaft 300, it is difficult to separately adjust the size of the gap between the bearing 400 and the wing plate 100. In this embodiment, it is convenient to adjust the position of the bearing 400 by adjusting the position of the outer shaft 300.

In one embodiment, the distance between the end of the outer shaft 300 remote from the wing 100 and the wing 100 is less than the distance between the end of the inner shaft 200 remote from the wing 100 and the wing 100.

Further, the end of inner shaft 200 remote from wing plate 100 is polygonal to facilitate tool gripping. The polygon may be a quadrangle, a pentagon, a hexagon, an octagon, etc., which should not be construed as a limitation.

In one embodiment, the outer shaft 300 is secured to the inner shaft 200 by an interference fit. It will be understood by those skilled in the art that there are various methods for forming the eccentric shaft by the outer shaft 300 and the inner shaft 200, such as integral molding. In the present embodiment, the interference fit is used. Specifically, an axial through hole that does not overlap with the central axis is formed in the outer shaft 300, and then the eccentric shaft formed by the outer shaft 300 and the inner shaft 200 in the present embodiment can be formed by sleeving the axial through hole on the inner shaft 200 in an interference fit manner. The interference fit mode is adopted, the processing difficulty of the outer shaft 300 and the inner shaft 200 can be reduced, and the cost is saved.

In one embodiment, the guide wheel mechanism of the novel cigarette making machine wing plate 100 further comprises an isolation pad 500, the isolation pad 500 is sleeved on the inner shaft 200, and the isolation pad 500 is located between the outer shaft 300 and the wing plate 100. By providing the spacer 500, the gap between the side of the bearing 400 close to the wing plate 100 and the wing plate 100 can be precisely adjusted. Meanwhile, the gap between the bearing 400 and the wing plate 100 can be maintained, so that the wing plate 100 is further prevented from directly bearing the vibration and heat generated when the bearing 400 operates at high speed, and the service life of the wing plate 100 is prolonged.

In one embodiment, the diameter of the spacer 500 is smaller than the diameter of the inner race of the bearing 400. As known to those skilled in the art, the inner ring of the bearing 400 is fixed, the outer ring of the bearing 400 rotates at a high speed, and the isolation pad 500 is pressed between the bearing 400 and the wing plate 100, so that the outer ring of the bearing 400 is prevented from generating friction with the isolation pad 500 during the rotation process, and the bearing 400 is ensured to run stably.

In one embodiment, the guide wheel mechanism of the novel cigarette machine wing plate 100 further comprises a jackscrew, the wing plate 100 is further provided with a threaded hole, the threaded hole penetrates through the peripheral wall of the mounting hole, and the jackscrew penetrates through the threaded hole and abuts against the peripheral wall of the part of the inner shaft 200, which is located in the mounting hole. The fixing is realized through the jackscrew, the operation is simple, and the installation space is not occupied.

In one embodiment, the number of the jackscrews is two. Thus, the inner shaft 200 can be further fixed and fixed. It will be understood by those skilled in the art that three, four, or five jackscrews may be used to fix inner shaft 200 in the embodiments of the present application.
