Fig. 2 shows a mounting form of an acceleration wheel of a rod making machine in the related art on a mounting base 3'. The accelerator wheel consists of an integrally formed wheel body 10 'and wheel axle 20'. The wheel axle 20 'passes through the mounting seat 3' and is rotatably mounted on the mounting seat 3 'around the axis thereof through the first bearing 51' and the second bearing 52', the first end of the wheel axle 20' is integrally connected with the wheel body 10', the driving wheel 4' is mounted on the second end of the wheel axle 20 'through the connecting key 8', and the end face of the driving wheel 4 'far away from one side of the wheel body 10' is also provided with the disc spring 6 'and the retainer ring 7', so as to limit the relative positions of the driving wheel 4 'and the wheel axle 20', and keep the relative fixation of the driving wheel 4 'and the wheel axle 20'. The power system of the filter stick forming machine inputs the power for driving the accelerating wheel to rotate to the accelerating wheel through the driving wheel 4'.
For the accelerator wheel with the integrally formed wheel body 10 'and wheel axle 20', when the accelerator wheel with different specifications is replaced, the retainer ring 7 'and the disc spring 6' are required to be detached from the driving wheel 4', then the driving wheel 4' and the connecting key 8 'are required to be detached from the wheel axle 20', then the wheel axle 20 'together with the first bearing 51' and other parts are required to be detached from the mounting seat 3', finally the first bearing and other parts are required to be detached from the wheel axle 20', the process of detaching the accelerator wheel involves a plurality of different parts, and the steps are complex and the consumed time is long. Moreover, among the various components, the retainer ring 7' needs to be removed by means of a tool such as a clamp spring pliers, the driving wheel 4' needs to be removed from the end of the wheel shaft 20' by means of prying or pulling by a screwdriver, the wheel shaft 20' together with the first bearing 51' needs to be removed by means of a copper rod or other tool, and the second bearing 52' may be carelessly knocked when the wheel shaft 20' is knocked. It can be seen that during use of these tools, damage is easily caused to the structure of the accelerator wheel itself, the key ways on the axle 20', and the like, as well as the associated first bearing 51', second bearing 52', and retainer ring 7', and the like.
To ameliorate the above problems, referring to fig. 3 to 8, some embodiments of the present disclosure provide an acceleration wheel of a filter rod forming machine, including a wheel body 10 and a wheel shaft 20. The wheel shaft 20 is provided separately from the wheel body 10, and is configured to be rotatably mounted to the mount 3 of the accelerator wheel about its own axis. Wherein, the wheel body 10 is provided with a first connection structure, the wheel axle 20 is provided with a disassembly end, the disassembly end is provided with a second connection structure, and the wheel body 10 is detachably connected to the disassembly end through the first connection structure and the second connection structure, so that the wheel body 10 can be disassembled from the wheel axle 20 at the disassembly end or mounted to the wheel axle 20.
The first connecting structure and the second connecting structure can be directly fixed relatively through mutual connection, and can also be fixed relatively through fasteners, so that the wheel body 10 and the wheel shaft 20 are kept relatively fixed. Optionally, referring to fig. 4, 6 and 7, the end of the axle 20 opposite the removable end is provided with a keyway 23 for connection with the drive wheel 4 by means of a connecting key 8.
In the accelerating wheel provided by the embodiment of the disclosure, the wheel body 10 and the wheel shaft 20 which are arranged in a split manner are detachably connected at the dismounting end of the wheel shaft 20 through the first connecting structure and the second connecting structure, when the accelerating wheels with different specifications are required to be replaced, the wheel body 10 with the current specification is only required to be dismounted from the dismounting end of the wheel shaft 20, and then the wheel body 10 with the required specification is required to be mounted on the dismounting end of the wheel shaft 20, so that the wheel shaft 20 is not required to be dismounted from the mounting seat 3, the mode of replacing the whole accelerating wheel is replaced by adopting the mode of replacing the wheel body 10, and the working hours of 80% -90% can be saved.
Therefore, compared with the accelerator wheel in the related art, the accelerator wheel provided by the embodiment of the disclosure can simplify the disassembly and assembly process of the accelerator wheel when the filter rod specification produced by the filter rod forming machine is changed, and can prevent unnecessary damage to the accelerator wheel, a key slot, a bearing, a retainer ring and other parts.
In some embodiments, referring to fig. 3 and 7, the wheel body 10 and axle 20 are connected by threaded fasteners s to remain relatively stationary.
In this embodiment, the threaded fastener s is an easily detachable fastener, which is beneficial to further improving the efficiency of detaching or installing the wheel body 10. Alternatively, referring to fig. 7, the threaded fastener s is a screw. The disassembling and assembling screw only needs to be operated on one side of the wheel body 10 far away from the mounting seat 3, and the operation space is sufficient. By adopting the disassembly method of the embodiment, the working time required for replacing the accelerator wheel specification can be reduced from about 1 hour to about 5 minutes in the related art.
In some embodiments, referring to fig. 4 to 7, the wheel body 10 has a through hole 13 for passing the threaded fastener s, the detachable end of the wheel axle 20 has a screw hole 22 for mating with the threaded fastener s, and the first and second connection structures are capable of mating with each other and configured to restrict relative rotation of the wheel body 10 and the wheel axle 20 about the axis of the through hole 13 in the mated state.
In this embodiment, the first connection structure and the second connection structure are mutually matched to limit the relative rotation of the wheel body 10 and the wheel shaft 20 around the axis of the through hole 13, and when the threaded fastener s is screwed, the wheel body 10 and the wheel shaft 20 can be prevented from generating relative rotation under the action of the torque of screwing the threaded fastener s, so that the convenience of disassembling or assembling the wheel body 10 is further improved.
In some embodiments, the first connection structure and the second connection structure are male-female mating structures.
In this embodiment, the concave-convex matching structure can realize the relative positioning of the wheel body 10 and the wheel axle 20. For the wheel body 10 and the wheel shaft 20 relatively fixed by the screw fastener s, the wheel body 10 can be positioned in advance with respect to the wheel shaft 20 by the male-female fitting structure when the wheel body 10 is mounted, so that the through hole 13 is aligned with the screw hole 22, thereby facilitating screwing of the screw fastener s.
In some embodiments, referring to fig. 4 to 7, the first connection structure is a positioning groove 11, and the second connection structure is a positioning body 21 mated with the first connection structure.
Alternatively, in view of the small dimension of the wheel body 10 in the axial direction thereof, referring to fig. 4 and 6, the positioning body 21 has a plate shape, and the thickness direction of the positioning body 21 is the axial direction of the wheel shaft 20. Alternatively, the positioning groove 11 does not penetrate the wheel body 10 in the axial direction of the wheel body 10.
In some embodiments, the positioning body 21 is formed at the outer periphery of the axle 20 and extends radially outward of the axle 20.
In this embodiment, referring to fig. 4, the positioning body 21 has an end surface perpendicular to the axis of the axle 20 and connected to the outer periphery of the detachable end, and the end surface can be used to position a washer, a bearing, or the like fitted over the axle 20 in the axial direction of the axle 20 at the detachable end.
While it is not necessary to disassemble the axle 20 when changing the filter rod specifications produced by the filter rod making machine, it is sometimes necessary to replace the sleeved bearings and other components on the axle 20 due to the maintenance and repair of the associated components in accordance with the concepts of the embodiments of the present disclosure.
In some embodiments, the outer contour of the cross section of the positioning body 21 perpendicular to the axis of the axle 20 has two parallel sides.
The distance between the two parallel sides may be determined according to the outer diameter of the bearing fitted over the axle 20, and may be set smaller than the outer diameter of the bearing.
In this embodiment, the cross-section of the above form takes into account the need to disassemble the components, such as the bearings, that are mounted on the axle 20. When the first bearing 51 needs to be replaced, the wheel shaft 20 together with the first bearing 51 and the like may be first removed from the mount 3 in the manner described in the related art. Referring then to fig. 8, the gap between the two jaws 9 of the bench vice is adjusted to a distance d that is greater than the distance between the two parallel sides and less than the outer diameter of the first bearing 51. The attitude of the wheel axle 20 is then adjusted so that the two parallel sides are substantially parallel to the two jaws 9, and portions of the outer race of the first bearing 51 that are located outside the two parallel sides are placed on the two jaws 9, respectively. Finally, the end of the axle 20 opposite to the disassembly end is knocked along the axial direction of the axle 20 (i.e. the direction perpendicular to the paper surface in fig. 8), so that the axle 20 can be removed from the inner ring of the first bearing 51. The disassembly process is simple to operate, convenient to implement and high in disassembly efficiency.
In some embodiments, the outer contour of the cross section of the positioning body 21 perpendicular to the axis of the axle 20 is quadrilateral or hexagonal.
Alternatively, referring to fig. 4 and 6, the outer profile of the cross section of the positioning body 21 perpendicular to the axis of the wheel axle 20 is a regular hexagon, and the cross section of the positioning groove 11 perpendicular to the axis of the wheel body 10 is also a regular hexagon. Alternatively, in some embodiments, not shown, the outer profile of the cross section of the positioning body 21 perpendicular to the axis of the axle 20 is square, as is the cross section of the positioning groove 11 perpendicular to the axis of the wheel body 10.
In this embodiment, the outer contour of the cross section of the positioning body 21 perpendicular to the axis of the wheel axle 20 is set to be quadrilateral or hexagonal, which not only can limit the relative rotation of the positioning body 21 and the positioning groove 11, thereby limiting the relative rotation of the wheel body 10 and the wheel axle 20, but also the quadrilateral and hexagonal contour is convenient for processing the positioning body 21 and the positioning groove 11 adapted thereto, which is beneficial for reducing the manufacturing cost of the wheel axle 20 and the wheel body 10.
In some embodiments, referring to fig. 4 and 8, the accelerator wheel includes a plurality of wheel bodies 10 selectively mounted to wheel shafts 20, each wheel body 10 being provided with a guide groove 12 extending circumferentially thereabout on a circumferential outer side thereof, the guide grooves 12 of different wheel bodies 10 being different in depth.
The guide groove 12 is configured to form a receiving space required for conveying the molded filter rod. In this embodiment, the guide grooves 12 with different depths are provided in different wheel bodies 10, and when the filter rod specifications produced by the filter rod forming machine are changed, the wheel body 10 with the guide groove 12 with the corresponding depth is selected according to the required filter rod specifications, and is mounted on the mounting and dismounting end of the wheel shaft 20. After the two wheel bodies 10 are installed in place, the distance between the bottoms of the guide grooves 12 of the two wheel bodies 10 along the connecting line direction of the axes of the two parallel accelerating wheels is the diameter of the filter stick to be produced.
Some embodiments of the present disclosure also provide a filter rod forming machine including the acceleration wheel provided by embodiments of the present disclosure.
Embodiments of the present disclosure provide a filter rod forming machine having the advantages of the acceleration wheel provided by the embodiments of the present disclosure.
