[0044] Please refer to Figures 1 to 5In one embodiment, a slitting hub wheel module 100 is provided, which comprises a slitting hub wheel and a cover plate 50. The slitting hub wheel comprises a mounting member 10, a hub wheel shaft 20, a hub wheel body 30 and a receiving member 40. The mounting member 10 is a mounting support structure of the entire hub wheel, which is used to connect with the structure on the slitting device, so as to mount and fix the entire slitting hub wheel, for example, the mounting member 10 is used to connect with the back plate 200 on the slitting device, so as to mount the entire slitting hub wheel on the back plate 200. The hub wheel shaft 20 is rotatably arranged on the mounting member 10, which is mainly used to connect with the driving mechanism, so as to rotate under the driving of the driving mechanism. The hub wheel body 30 is connected with the hub wheel shaft 20, and the receiving member 40 is arranged on the outer periphery of the hub wheel body 30, and the outer periphery of the receiving member 40 is provided with filter rod grooves 41 for accommodating filter rods and cutter grooves 42 for avoiding cutters. The receiving member 40 is mainly used to receive and accommodate filter rods, and the filter rod grooves 41 are arranged to correspond to the accommodation of filter rods. Under the rotation of the hub wheel shaft 20, the receiving member 40 can be driven to rotate synchronously, so as to convey the filter rods to the cutter position for slitting. The cover plate 50 is detachably arranged at the slitting position of the slitting hub wheel, and the cover plate 50 is spaced from the receiving member 40. The cover plate 50 is provided with cutter avoiding grooves 51 corresponding to the cutter grooves 42. Wherein, the cover plate 50 is provided with cutter avoiding grooves 51 corresponding to the cutter grooves 42, which means that the number and axial position of the cutter avoiding grooves 51 arranged on the cover plate 50 correspond to the number and axial position of the cutter grooves 42 arranged on the receiving member 40, so that each cutter groove 42 corresponds to a cutter avoiding groove 51 when the cutter groove 42 on the receiving member 40 rotates to the slitting position. The cutter avoiding grooves 51 can avoid the cutters, so as not to affect the normal slitting of the cutters on the filter rods. The cover plate 50 is used to press the filter rods in the filter rod grooves 41. Specifically, the interval distance between the inner wall of the cover plate 50 and the groove bottom of the filter rod groove 41 is less than the diameter of the required slitting filter rod.

[0045] The main function of the cover plate 50 is to press the filter rods to slight deformation, so as to prevent the filter rods from rotating in the filter rod grooves 41, which causes poor slitting effect. Specifically, when the filter rod groove 41 rotates to the slitting position, the inner wall of the cover plate 50 will correspondingly press the filter rods, so as to press the filter rods in the filter rod groove 41, thereby avoiding the rotation of the filter rods in the filter rod groove 41 when the cutters cut the filter rods.

[0046] It can be understood that in the prior art, when the cutters cut the filter rods in the slitting hub wheel, the filter rods are easy to rotate in the filter rod grooves of the slitting hub wheel, which causes poor slitting effect.

[0047] The cover plate 50 is arranged in the cutting hub wheel module 100, and the filter rod can be prevented from rotating in the filter rod slot 41, so that the cutting effect on the filter rod is improved.

[0048] Specifically, the cover plate 50 can be installed on the back plate 200 or the cutting hub wheel (for example, the mounting piece 10), and only a part of the structure on the cover plate 50 is located at the cutting position of the cutting hub wheel and is spaced from the containing piece 40, so that the filter rod located at the cutting position can be pressed by the corresponding structure on the cover plate 50.

[0049] Preferably, in an embodiment, the accommodating member 40 comprises a fixed part 43 and a movable part 44, the fixed part 43 is arranged at the outer periphery of the hub wheel body 30, and the outer periphery of the fixed part 43 is sequentially and spacedly provided with a plurality of first pieces 431. The movable part 44 is arranged on the fixed part 43, and the movable part 44 is provided with a plurality of second pieces 441. Each two adjacent first pieces 431 are provided with a second piece 441 therebetween, and the second piece 441 is spaced from the first piece 431 to form the filter rod slot 41. That is, the second piece 441 is inserted into the position area between two adjacent first pieces 431, and each position area between two adjacent first pieces 431 is inserted with a second piece 441, so that the distribution of each piece along the circumference of the accommodating member 40 is: the first piece 431, the second piece 441, the first piece 431, the second piece 441, and so on. The filter rod slot 41 is opened between the first piece 431 and the second piece 441, and the circumferential edge of the second piece 441 and the circumferential edge of the first piece 431 constitute part of the filter rod slot 41, so that the slot width of the filter rod slot 41 can be adjusted by adjusting the spacing distance between the second piece 441 and the first piece 431. Along the circumference of the accommodating member 40, the movable part 44 has a plurality of mounting positions on the fixed part 43, that is, the movable part 44 and the fixed part 43 have not only one mounting position, but also a plurality of mounting positions along the circumference. The relative position of the movable part 44 and the fixed part 43 can be adjusted by rotating the movable part 44 relative to the fixed part 43, and after adjusting the relative position, the movable part 44 can still be mounted and fixed on the fixed part 43. Since the movable part 44 is provided with the second piece 441, the spacing distance between the second piece 441 and the first piece 431 can be adjusted simultaneously after adjusting the position of the movable part 44, so as to correspondingly adjust the slot width of the filter rod slot 41. It can be understood that the filter rod in the prior art has a plurality of different diameter specifications, and by arranging the accommodating member 40 as two components that can be adjusted in relative rotation position, the slot width of the filter rod slot 41 can be adaptively adjusted according to production requirements, so that the slitting hub wheel can be adapted to different diameter filter rods for production and use.

For example, one of the filter rod grooves 41 is dedicated to fit thin filter rods, and the positions of the cutter grooves 42 distributed on this filter rod groove 41 correspond to the positions of the cutter for thin filter rods; another of the filter rod grooves 41 is dedicated to fit thick filter rods, and the positions of the cutter grooves 42 distributed on this filter rod groove 41 correspond to the positions of the cutter for thick filter rods.

[0051] Since the accommodating member 40 can be used to fit filter rods with different diameters, in order to adapt to the production of filter rods with different diameters, the cover plate 50 has multiple specifications, and when the accommodating member 40 is adjusted to adapt to the groove width, the corresponding specification of the cover plate 50 can be installed to adapt to the required production of filter rods. Specifically, taking the filter rods commonly used in the prior art as an example, 5.4 mm and 6.3 mm filter rods share the same thickness of the cover plate 50, and 7.1 mm and 7.4 mm filter rods share another thickness of the cover plate 50. In addition, considering the cutter grooves 42 distributed on different filter rod grooves 41, the cover plate 50 is provided with four different positions of the cutter avoiding grooves 51.
