Description

Technical Field

[0001] The present disclosure relates to the field of accessories for filter rod forming equipment, and particularly to an acceleration wheel of a filter rod forming machine and a filter rod forming machine. Background Art

[0002] The acceleration wheel is one of the important components on the filter rod forming machine. Referring to Figure 1 , the formed filter rod is cut into filter rod segments 92' of uniform length. The filter rod segments 92' pass through the space between the outer circumferences of two juxtaposed acceleration wheels 91', and are accelerated under the extrusion of the acceleration wheels 91', and are successively conveyed into different adsorption grooves on the smoke dividing wheel 93'. The filter rod segments 92' are decelerated and adsorbed under the action of negative pressure in the adsorption grooves. As the smoke dividing wheel 93' rotates, the filter rod segments 92' are conveyed to the turning wheel, and successively pass through the turning wheel, the intermediate wheel, the output wheel and the output channel, and are further conveyed to the tray loader.

[0003] In order to adapt to the production of filter rods of different specifications, it is necessary to correspondingly replace acceleration wheels 91' of different specifications so that the diameter of the guide grooves on the outer circumferences of the two acceleration wheels 91' matches the diameter of the filter rod. However, for the current mainstream filter rod forming machines, such as the KDF2 type filter rod forming machine, its acceleration wheel is usually an integral acceleration wheel. When disassembling the acceleration wheel, there are many components that need to be disassembled together. The disassembly and assembly process is complex, time-consuming, and it is easy to damage the acceleration wheel itself and related supporting components during the disassembly process. Summary of the Utility Model

[0004] The purpose of the present disclosure is to provide an acceleration wheel of a filter rod forming machine and a filter rod forming machine to simplify the disassembly and assembly process of the acceleration wheel when changing the specifications of the filter rods produced by the filter rod forming machine.

[0005] The first aspect of the present disclosure provides an acceleration wheel of a filter rod forming machine, including:

[0006] a wheel body; and

[0007] a wheel shaft, which is separately arranged from the wheel body and is configured to be rotatably mounted on the mounting seat of the acceleration wheel around its own axis;

[0008] wherein, the wheel body is provided with a first connection structure, the wheel shaft has a disassembly and assembly end, the disassembly and assembly end is provided with a second connection structure, and the wheel body is detachably connected to the disassembly and assembly end through the first connection structure and the second connection structure, so that the wheel body can be detached from the wheel shaft or installed on the wheel shaft at the disassembly and assembly end.

[0009] In some embodiments, the wheel body and the wheel shaft are connected by threaded fasteners to maintain relative fixation.

[0010] In some embodiments, the wheel body has a through hole for passing through the threaded fastener, and the disassembly and assembly end of the wheel shaft has a threaded hole for cooperating with the threaded fastener. The first connection structure and the second connection structure can cooperate with each other and are configured to limit the relative rotation of the wheel body and the wheel shaft around the axis of the through hole in the state of mutual cooperation.

[0011] In some embodiments, the first connection structure and the second connection structure are concave-convex mating structures.

[0012] In some embodiments, the first connection structure is a positioning groove, and the second connection structure is a positioning body that cooperates with the first connection structure.

[0013] In some embodiments, the positioning body is formed on the outer periphery of the wheel shaft and extends radially outward of the wheel shaft.

[0014] In some embodiments, the outer contour of the cross section of the positioning body perpendicular to the axis of the wheel shaft has two parallel sides.

[0015] In some embodiments, the outer contour of the cross section of the positioning body perpendicular to the axis of the wheel shaft is a quadrilateral or a hexagon.

[0016] In some embodiments, it includes a plurality of wheel bodies that can be selectively installed on the wheel shaft. A guiding groove extending along its own circumferential direction is provided on the circumferential outer side of each wheel body, and the depths of the guiding grooves of different wheel bodies are different.

[0017] The second aspect of the present disclosure provides a filter rod forming machine, including the accelerating wheel according to the first aspect of the present disclosure.

[0018] In the accelerating wheel provided by the embodiments of the present disclosure, the wheel body and the wheel shaft that are separately provided are detachably connected at the disassembly and assembly end of the wheel shaft through the first connection structure and the second connection structure. When it is necessary to replace accelerating wheels of different specifications, only the wheel body of the current specification needs to be removed from the disassembly and assembly end of the wheel shaft, and then the wheel body of the required specification can be installed on the disassembly and assembly end of the wheel shaft, without having to disassemble the wheel shaft from the mounting seat. The method of replacing the wheel body replaces the method of replacing the entire accelerating wheel, and can save 80% - 90% of the disassembly time.

[0019] Therefore, compared with the accelerating wheel in the related art, the accelerating wheel provided by the embodiments of the present disclosure can simplify the disassembly and assembly process of the accelerating wheel when changing the specifications of the filter rods produced by the filter rod forming machine, and can prevent unnecessary damage to the accelerating wheel itself and related components such as key grooves, bearings, and retaining rings.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

Without otherwise stating, the above terms have no special meanings and thus cannot be construed as limiting the scope of protection of the present disclosure.

[0039] Figure 2 shows the installation form of the acceleration wheel of a filter rod forming machine in the related art on the mounting seat 3'. The acceleration wheel is composed of a wheel body 10' and a wheel shaft 20' integrally formed. The wheel shaft 20' passes through the mounting seat 3' and is rotatably mounted on the mounting seat 3' about its own axis through a first bearing 51' and a second bearing 52'. A wheel body 10' is integrally connected to the first end of the wheel shaft 20'. A transmission wheel 4' is mounted on the second end of the wheel shaft 20' through a connection key 8'. A disc spring 6' and a retaining ring 7' are further provided on the end face of the transmission wheel 4' on the side away from the wheel body 10' to limit the relative position of the transmission wheel 4' and the wheel shaft 20' and keep the relative fixation of the transmission wheel 4' and the wheel shaft 20'. The power system of the filter rod forming machine inputs the power for driving the acceleration wheel to rotate to the acceleration wheel through the transmission wheel 4'.

[0040]

[0039] For the acceleration wheel with the wheel body 10' and the wheel shaft 20' integrally formed, when replacing acceleration wheels of different specifications, it is necessary to first remove the retaining ring 7' and the disc spring 6' from the transmission wheel 4', then remove the transmission wheel 4' and the connection key 8' from the wheel shaft 20', then remove the wheel shaft 20' together with components such as the first bearing 51' from the mounting seat 3', and finally remove the components such as the first bearing from the wheel shaft 20'. The process of disassembling the acceleration wheel involves multiple different components, with complex steps and a long time-consuming. Moreover, among the multiple components, the retaining ring 7' needs to be removed by relying on tools such as a circlip pliers, the transmission wheel 4' needs to be removed from the end of the wheel shaft 20' by relying on the way of prying with a screwdriver or pulling with a puller, and the wheel shaft 20' together with the first bearing 51' needs to be removed from the mounting seat 3' by knocking with a copper rod or other tools. When knocking the wheel shaft 20', it may accidentally knock on the second bearing 52'. Thus, in the process of using these tools, it is easy to cause damage to the acceleration wheel itself, structures such as the keyway on the wheel shaft 20', and supporting components such as the first bearing 51', the second bearing 52' and the retaining ring 7'.

[0041] To improve the above problems, referring to Figures 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 separately arranged from the wheel body 10 and is configured to be rotatably mounted on the mounting seat 3 of the acceleration wheel about its own axis. Among them, the wheel body 10 is provided with a first connection structure, the wheel shaft 20 has a disassembly and assembly end, and a second connection structure is provided at the disassembly and assembly end. The wheel body 10 is detachably connected to the disassembly and assembly end through the first connection structure and the second connection structure, so that the wheel body 10 can be removed from the wheel shaft 20 or installed on the wheel shaft 20 at the disassembly and assembly end.

[0042] The first connection structure and the second connection structure can directly achieve relative fixation through mutual connection, or can achieve relative fixation through fasteners, so that the wheel body 10 and the wheel shaft 20 are kept relatively fixed. Optionally, referring toFigure 4 , Figure 6 and Figure 7 , a keyway 23 is provided at one end of the axle 20 opposite to the disassembly and assembly end, so as to be connected to the transmission wheel 4 through the connection key 8.

[0043] In the accelerating wheel provided by the embodiment of the present disclosure, the separately arranged wheel body 10 and the axle 20 are detachably connected at the disassembly and assembly end of the axle 20 through the first connection structure and the second connection structure. When it is necessary to replace the accelerating wheel with different specifications, only the current specification of the wheel body 10 needs to be removed from the disassembly and assembly end of the axle 20, and then the required specification of the wheel body 10 is installed at the disassembly and assembly end of the axle 20, without having to disassemble the axle 20 from the mounting seat 3. The method of replacing the wheel body 10 is adopted to replace the method of replacing the entire accelerating wheel, which can save 80% - 90% of the working hours.

[0044] Therefore, compared with the accelerating wheel in the related art, the accelerating wheel provided by the embodiment of the present disclosure can simplify the disassembly and assembly process of the accelerating wheel when changing the filter rod specifications produced by the filter rod forming machine, and can prevent unnecessary damage to the accelerating wheel itself and related components such as keyways, bearings and retaining rings.

[0045] In some embodiments, referring to Figure 3 and Figure 7 , the wheel body 10 and the axle 20 are connected by a threaded fastener s to keep relatively fixed.

[0046] In this embodiment, the threaded fastener s is a fastener that is easy to disassemble and assemble, which is beneficial to further improving the efficiency of disassembling or installing the wheel body 10. Optionally, referring to Figure 7 , the threaded fastener s is a screw. Disassembling and assembling the screw only needs to be operated on the side of the wheel body 10 away from the mounting seat 3, and the operating space is sufficient. By adopting the disassembly method of this embodiment, the working hours required to change the accelerating wheel specifications can be reduced from about 1 hour in the related art to about 5 minutes.

[0047] In some embodiments, referring to Figures 4 to 7 , the wheel body 10 has a through hole 13 for passing through the threaded fastener s, and the disassembly and assembly end of the axle 20 has a threaded hole 22 for cooperating with the threaded fastener s. The first connection structure and the second connection structure can cooperate with each other and are configured to limit the relative rotation of the wheel body 10 and the axle 20 around the axis of the through hole 13 in the state of mutual cooperation.

[0048] Installing or disassembling the wheel body 10 requires screwing the threaded fastener s. In this embodiment, the first connection structure and the second connection structure limit the relative rotation of the wheel body 10 and the axle 20 around the axis of the through hole 13 through mutual cooperation. When screwing the threaded fastener s, the relative rotation of the wheel body 10 and the axle 20 under the action of the torque of screwing the threaded fastener s can be prevented, further improving the convenience of disassembling or installing the wheel body 10.

[0049] In some embodiments, the first connection structure and the second connection structure are a male-female mating structure.

[0050] In this embodiment, the male-female mating structure can achieve relative positioning of the wheel body 10 and the wheel axle 20. For the wheel body 10 and the wheel axle 20 that are relatively fixed by the threaded fastener s, when installing the wheel body 10, the wheel body 10 can be pre-positioned relative to the wheel axle 20 through the male-female mating structure, so that the through hole 13 is aligned with the threaded hole 22, thereby facilitating the screwing of the threaded fastener s.

[0051] In some embodiments, referring to Figures 4 to 7 , the first connection structure is a positioning groove 11, and the second connection structure is a positioning body 21 that mates with the first connection structure.

[0052] Optionally, considering that the dimension of the wheel body 10 along its own axial direction is small, referring to Figure 4 and Figure 6 , the positioning body 21 is plate-shaped, and the thickness direction of the positioning body 21 is the axial direction of the wheel axle 20. Optionally, along the axial direction of the wheel body 10, the positioning groove 11 does not penetrate the wheel body 10.

[0053] In some embodiments, the positioning body 21 is formed on the outer periphery of the wheel axle 20 and extends radially outward of the wheel axle 20.

[0054] In this embodiment, referring to Figure 4 , the positioning body 21 has an end face perpendicular to the axis of the wheel axle 20 and connected to the outer periphery of the disassembly and assembly end, and this end face can be used to position components such as washers and bearings sleeved on the wheel axle 20 along the axial direction of the wheel axle 20 at the disassembly and assembly end.

[0055] According to the concept of the embodiments of the present disclosure, although it is not necessary to disassemble the wheel axle 20 when changing the filter rod specifications produced by the filter rod forming machine, sometimes it is also necessary to replace components such as bearings sleeved on the wheel axle 20 for the maintenance and servicing of related components.

[0056] In some embodiments, the outer contour of the cross-section of the positioning body 21 perpendicular to the axis of the wheel axle 20 has two parallel sides.

[0057] The distance between the two parallel sides can be determined according to the outer diameter of the bearing sleeved on the wheel axle 20, and this distance can be set to be less than the outer diameter of the bearing.

[0058] In this embodiment, the cross-section in the above form takes into account the need to disassemble components such as bearings sleeved on the wheel axle 20. When it is necessary to replace the first bearing 51, the method in the related art mentioned above can be referred to. First, the wheel axle 20 together with components such as the first bearing 51 is removed from the mounting seat 3. Then referring to Figure 8, adjust the distance between the two jaws 9 of the bench vise to a distance d, which is greater than the distance between the two parallel edges and less than the outer diameter of the first bearing 51. Then adjust the posture of the axle 20 so that the two parallel edges are roughly parallel to the two jaws 9, and the outer ring of the first bearing 51 outside the two parallel edges is placed on the two jaws 9 respectively. Finally, along the axial direction of the axle 20 (i.e. Figure 8 By tapping the end of the axle 20 opposite to the disassembly end (in the direction perpendicular to the paper surface), the axle 20 can be removed from the inner ring of the first bearing 51. The above disassembly process is simple to operate, easy to implement, and has high disassembly efficiency.

[0059] In some embodiments, the outer contour of the cross section of the positioning body 21 perpendicular to the axis of the axle 20 is a quadrilateral or a hexagon.

[0060] Optionally, refer to Figure 4 and Figure 6 , the outer contour 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. Optionally, in some embodiments not shown, the outer contour of the cross section of the positioning body 21 perpendicular to the axis of the wheel axle 20 is a square, and the cross section of the positioning groove 11 perpendicular to the axis of the wheel body 10 is also a square.

[0061] 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 a quadrilateral or a hexagon, which can not only 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 contours facilitate the processing of the positioning body 21 and the positioning groove 11 adapted thereto, which is beneficial to reducing the manufacturing cost of the wheel axle 20 and the wheel body 10.

[0062] In some embodiments, reference Figure 4 and Figure 8 The acceleration wheel includes a plurality of wheel bodies 10 which can be selectively mounted on the wheel axle 20. A guide groove 12 extending along its own circumference is arranged on the circumferential outer side of each wheel body 10. The depths of the guide grooves 12 of different wheel bodies 10 are different.

[0063] The guide groove 12 is configured to form a receiving space required for conveying and forming the filter rod. In this embodiment, different wheel bodies 10 are provided with guide grooves 12 of different depths. When the filter rod specifications produced by the filter rod forming machine are changed, the wheel body 10 with the guide groove 12 of the corresponding depth is selected according to the required filter rod specifications, and it is installed to the disassembly end of the wheel axle 20. After the two wheel bodies 10 are installed in place, along the connecting direction of the axes of the two acceleration wheels arranged side by side, the distance between the bottoms of the guide grooves 12 of the two wheel bodies 10 is the diameter of the filter rod to be produced.

[0064] Some embodiments of the present disclosure also provide a filter rod forming machine, including an acceleration wheel provided by the embodiments of the present disclosure.

[0065] The filter rod forming machine provided by the embodiments of the present disclosure has the advantages of the acceleration wheel provided by the embodiments of the present disclosure.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present disclosure or perform equivalent replacements on some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
