DETAILED DESCRIPTION

[0026] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0027] Please refer to Figures 1-7 The cigarette separating wheel assembly in the embodiment of the present application comprises a left half wheel body 1 and a right half wheel body 2 which are both annular and connected with each other, and a plurality of driving members arranged on the left half wheel body 1 and the right half wheel body 2 respectively. At least one adsorption seat 4 capable of adsorbing a cigarette is arranged on the outer side of the left half wheel body 1 and the right half wheel body 2 along the circumference. The adsorption seats 4 on the left half wheel body 1 and the right half wheel body 2 are arranged one by one in correspondence, so that two cigarettes are arranged in correspondence. Two driving members are used to drive the corresponding adsorption seats 4 to turn around, so that the two cigarettes turn around and form a connecting gap for connecting a filter tip between the end close to each other.

[0028] Here, the left half wheel body 1 and the right half wheel body 2 are symmetrically arranged, the axis of the left half wheel body 1 and the axis of the right half wheel body 2 coincide, and the two corresponding suction seats 4 are symmetrically arranged. The two driving members move simultaneously, so that the two corresponding suction seats 4 rotate simultaneously, and after the two suction seats 4 rotate, the two corresponding cigarettes can be turned around simultaneously, thereby forming a connecting gap between the ends of the two cigarettes that are close to each other after turning around, and the filter is arranged in the connecting gap and can connect the two ends of the filter to the ends of the two cigarettes that are close to each other. In the prior art, the cigarette separating device first cuts the cigarette rod to form two cigarettes, at this time, the cut ends of the two cigarettes are arranged close to each other, at this time, the gap between the cut ends of the two cigarettes is not enough to install the filter. In order to install the filter between the cut ends of the two cigarettes, the two cigarettes are pulled away from each other to expand the gap, and then the filter is installed in the gap. However, special cigarettes have the requirement of installing filters on the non-cut ends, which cannot be met by the existing cigarette separating device. In the present application, after the cigarette rod of the special cigarette is cut, the two cigarettes are turned around so that the non-cut ends of the two cigarettes are arranged close to each other, and a connecting gap is formed between the non-cut ends of the two cigarettes. The filter is installed in the connecting gap, thereby realizing the connection of the two ends of the filter to the non-cut ends of the two cigarettes and meeting the requirement of installing filters on the non-cut ends of special cigarettes. Ordinary cigarettes can install filters on the non-cut ends, so the present application can also meet the requirement of installing filters on ordinary cigarettes. Therefore, the present application can not only be used in the production of ordinary cigarettes, but also meet the requirement of installing filters on the non-cut ends of some special cigarettes, and the applicability of the present cigarette separating wheel assembly is more extensive than that of the existing cigarette separating wheel.

[0029] Referring to Figures 1-2 , the driving member can include a plurality of driving rods 7, a plurality of transmission rods 5, a plurality of meshing tooth groups, a pushing member for pushing the driving rod 7 to move along the axial direction, the plurality of driving rods 7 are respectively arranged inside the left half wheel body 1 and the right half wheel body 2 along the axial direction, the driving rod 7 is arranged one by one with the transmission rod 5, the transmission rod 5 is arranged one by one with the suction seat 4, the plurality of transmission rods 5 are respectively connected to the corresponding suction seat 4 at one end and extend into the inside of the corresponding left half wheel body 1 or right half wheel body 2 at the other end; one end of the meshing tooth group is connected to the driving rod 7, and the other end is connected to the end of the transmission rod 5 extending into the inside of the corresponding half wheel, the meshing tooth group is used to drive the transmission rod 5 to rotate by a predetermined angle when the driving rod 7 slides along the axial direction, so that the transmission rod 5 drives the suction seat 4 to turn around.

[0030] Specifically, the axis of the drive rod 7 inside the left half-wheel body 1 is parallel to the axis of the left half-wheel body 1, and the axis of the drive rod 7 inside the right half-wheel body 2 is parallel to the axis of the right half-wheel body 2. Multiple adsorption seats 4 are respectively installed on the left half-wheel body 1 and the right half-wheel body 2. The drive rod 7 inside the left half-wheel body 1 or the right half-wheel body 2 meshes with the transmission rod 5 fixed on the corresponding adsorption seat 4. The cigarette is adsorbed on the adsorption seat 4. When the drive rod 7 slides axially, it can drive the transmission rod 5 and the adsorption seat 4 to rotate, so that the cigarette is turned around. The axial sliding directions of the drive rod 7 inside the left half-wheel body 1 and the drive rod 7 inside the right half-wheel body 2 are opposite. When the two symmetrical adsorption seats 4 on the left / right half-wheel body 2 rotate at the same time, the two corresponding cigarettes can be turned around to form a connecting gap between them for connecting the filter tip, so that the filter tip can be easily installed on the non-cut end of the cigarette.

[0031] See Figures 3-5 The adsorption seat 4 may include a seat body 4a and an adsorption part 4b connected to one side of the seat body 4a for adsorbing cigarettes. A first mounting hole 4f is provided through the seat body 4a, and one end of the transmission rod 5 is connected to the first mounting hole 4f.

[0032] Specifically, the adsorption part 4b is fixedly connected to one side of the base 4a, and the adsorption part 4b is in the shape of a long strip. The outer end of the transmission rod 5 is fixed in the first mounting hole 4f.

[0033] See Figures 3-5 One end of the adsorption part 4b, near the connection between the left half wheel body 1 and the right half wheel body 2, can protrude and be disposed on one side of the seat body 4a, while the other end of the adsorption part 4b, away from the connection between the left half wheel body 1 and the right half wheel body 2, is recessed and disposed on the other side of the seat body 4a, so that a clearance notch 4d is formed between the other end of the adsorption part 4b and the other side of the seat body 4a.

[0034] Specifically, the two suction seats 4 arranged on the left half wheel body 1 and the right half wheel body 2 are arranged opposite to each other or away from each other after being rotated simultaneously. During assembly, the end of the suction part 4b of the suction seat 4 on the left half wheel body 1 is arranged towards the right half wheel body 2, and the end of the suction part 4b of the suction seat 4 on the right half wheel body 2 is arranged towards the left half wheel body 1. After the cigarettes are sucked on the two suction seats 4, the cigarettes are close to each other. Thus, after the two suction seats 4 on the left half wheel body 1 and the right half wheel body 2 are rotated simultaneously, a larger connecting gap between the two rotated cigarettes is formed, which provides a larger operation space during the process of installing the filter on the cigarettes. Compared with the existing cigarette separating wheel, the larger gap between the suction seats 4 makes the application more widely applicable. The gap 4d ensures that the connecting gap between the suction parts 4b is wider after the two symmetrical suction seats 4 are rotated, which prevents the interference or collision of the two symmetrical cigarettes during the rotation and separation, and the wider connecting gap can install filter rods of different lengths, thereby enhancing the applicability of the application.

[0035] Specifically, the suction part 4b includes a base body and a movable body detachably connected to the base body. The movable body and the other side of the seat body 4a form a gap 4d. Different widths of the movable body are replaced, so that the width of the gap 4d can be adjusted, and the gap 4d can adapt to filter rods of different lengths.

[0036] Referring to Figures 1-7 The engagement teeth set can include first transmission teeth 7a arranged on the side surface of the driving rod 7 along the axial direction, and second transmission teeth 5a arranged on the side surface of the transmission rod 5 along the circumferential direction, and the second transmission teeth 5a are engaged with the first transmission teeth 7a.

[0037] Specifically, the first transmission teeth 7a are arranged along the axial direction of the driving rod 7, that is, the axis of the first transmission teeth 7a is parallel to the axis of the driving rod 7, and the axis of the transmission rod 5 can be perpendicular to the axis of the corresponding driving rod 7. The second transmission teeth 5a are arranged along the circumferential direction of the transmission rod 5, and the axis of the second transmission teeth 5a coincides with the axis of the transmission rod 5. The first transmission teeth 7a on the driving rod 7 are matched and engaged with the second transmission teeth 5a on the transmission rod 5. When the driving rod 7 slides axially, the transmission rod 5 rotates circumferentially through the cooperation between the first transmission teeth 7a and the second transmission teeth 5a, and finally completes the rotation of the suction seat 4. The cooperation between the first transmission teeth 7a and the second transmission teeth 5a makes the rotation more accurate, improves the applicability, and enhances the reliability of the device.

[0038] Referring to Figures 1-7The left half wheel body 1 and the right half wheel body 2 can be embedded with a plurality of support seats 6, the plurality of support seats 6 are arranged in one-to-one correspondence with the plurality of transmission rods 5, the middle part of the transmission rod 5 is rotationally connected to the support seat 6 through a bearing 9; a notch 6a is formed in the side surface of the support seat 6, the part of the driving rod 7 provided with the first transmission teeth 7a can pass through the notch 6a, and the part of the transmission rod 5 provided with the second transmission teeth 5a is arranged at a position matched with the notch 6a on the inner side of the support seat 6, so that the first transmission teeth 7a pass through the notch 6a and are engaged with the second transmission teeth 5a.

[0039] Specifically, the second mounting hole is formed in the left half wheel body 1 and the right half wheel body 2, and the plurality of support seats 6 can be clamped in the corresponding second mounting hole. The third mounting hole is formed in the support seat 6, and the bearing 9 is fixed in the third mounting hole, the middle part of the transmission rod 5 is sleeved with the bearing 9, and the transmission rod 5 is arranged in the third mounting hole of the support seat 6, and the transmission rod 5 and the support seat 6 are fixed in the axial direction. The transmission rod 5 is axially mounted on the support seat 6 and the adsorption seat 4, and is fixed on the support seat 6 through the bearing 9 to prevent the transmission rod 5 from moving up and down, and the notch 6a formed in the side of the support seat 6 is used to fix the driving rod 7, and the first transmission teeth 7a on the driving rod 7 are in contact with the second transmission teeth 5a on the transmission rod 5, which improves the applicability and enhances the reliability of the device.

[0040] The cigarette separating wheel assembly in the embodiment can further include an adsorption increasing structure for increasing the adsorption force of the adsorption part 4b.

[0041] Referring to Figures 1-7 The adsorption increasing structure can include a vacuumizing device, a first air channel 5b arranged in the transmission rod 5, a second air channel 4e arranged in the adsorption seat 4, and air holes 11 arranged on the inner side walls of the left half wheel body 1 and / or the right half wheel body 2, the inner port of the first air channel 5b is formed in the side wall of the part of the transmission rod 5 located in the corresponding left half wheel body 1 or right half wheel body 2, the outer port is formed in the side wall of the part of the transmission rod 5 extending into the first mounting hole 4f, the inner port of the second air channel 4e is in communication with the outer port of the first air channel 5b, and the outer port is formed in the side of the adsorption part 4b for adsorbing the cigarette, and one end of the air hole 11 is in communication with the inner port of the first air channel, and the other end is in communication with the vacuumizing device.

[0042] Specifically, the air hole 11 arranged on the inner side of the left / right half wheel body 2 is communicated with the inner port of the first air channel 5b in the transmission rod 5 at one end, and communicated with the vacuumizing device outside the device at the other end. The outer port of the first air channel 5b is communicated with the inner port of the second air channel 4e on the adsorption seat 4. The vacuumizing device enables the outer port of the second air channel 4e in the adsorption seat 4 to have adsorption force. Specifically, the outer port of the second air channel 4e is a plurality of through grooves. The cigarette is adsorbed on the corresponding adsorption part 4b by the adsorption force on the plurality of through grooves. Unlike the structure of adsorbing cigarettes on the existing separating wheel, the arrangement between the air hole 11 and the first air channel 5b and the second air channel 4e of the device can prevent the cigarette from falling when the adsorption seat 4 turns around and separates, thereby enhancing the applicability of the device.

[0043] Referring to Figures 1-7 , the pushing member can include two cams 3 arranged at the mutually far ends of the left half wheel body 1 and the right half wheel body 2 respectively, and two protruding parts 3a arranged on the two cams 3 respectively. The left end of each driving rod 7 in the left half wheel body 1 abuts against the corresponding cam 3, so that the protruding part 3a pushes the corresponding driving rod 7 to move right when the corresponding cam 3 rotates. The right end of each driving rod 7 in the right half wheel body 2 abuts against the corresponding cam 3, so that the protruding part 3a pushes the corresponding driving rod 7 to move left when the corresponding cam 3 rotates.

[0044] Specifically, the two cams 3 are annular, and the protruding part 3a is the farthest from the one end of the cam 3. The cam 3 drives the protruding part 3a to rotate when the cam 3 rotates, so that the protruding part 3a pushes the driving rod 7 to move. The protruding part 3a on the two cams 3 is arranged in a circular arc shape and is arranged in a symmetrical manner. When the driving rod 7 passes through the protruding part 3a of the cam 3, the driving rod 7 produces axial sliding, so that the first transmission teeth 7a on the driving rod 7 and the second transmission teeth 5a on the transmission rod 5 complete meshing movement, thereby improving the applicability and enhancing the reliability of the device.

[0045] Referring to Figures 1-7 , the pushing member can further include an annular stop part 7b arranged at one end of the driving rod 7 matched with the corresponding cam 3, a reset spring 8 sleeved on the middle part of the driving rod 7, and an annular abutting part 10 arranged in the left half wheel body 1 and / or the right half wheel body 2. The two ends of the reset spring 8 abut against the annular stop part 7b and the annular abutting part 10 respectively.

[0046] Specifically, when the driving rod 7 passes the protruding part 3a on the cam 3 to form an axial sliding movement, the annular stop part 7b on the driving rod 7 extrudes the reset spring 8 to abut against the annular abutting part 10 on the corresponding half wheel body, so that the driving rod 7 can always keep in contact with the surface of the cam 3 regardless of whether it passes the protruding part 3a on the cam 3. After the turning rotation of the adsorption seat 4 is completed and the cigarette is separated by being cut, the driving rod 7 no longer contacts the surface of the cam 3 and slides axially to abut against the surface of the cam 3, driving the adsorption seat 4 to rotate back to the original position in time. The cooperation between the cam 3, the driving rod 7 and the reset spring 8 improves the applicability and enhances the reliability of the structure of the device.

[0047] Specifically, the adsorption part 4b is provided with a positioning groove 4c, and the outer port of the second air channel 4e is arranged through the groove wall of the positioning groove 4c. The adsorption part 4b is arranged along the left-right direction, and one end of the adsorption part 4b extends out of the seat body 4a. When installed, the right end of the adsorption part 4b of the adsorption seat 4 on the left half wheel body 1 extends out of the right end surface of the seat body 4a, and the left end of the adsorption part 4b of the adsorption seat 4 on the right half wheel body 2 extends out of the left end surface of the seat body 4a, so that the two ends of the adsorption part 4b of the two symmetrical adsorption seats 4 extend out of the seat body 4a and are close to each other. The other end surface of the adsorption part 4b and the side surface of the seat body 4a to which the adsorption part 4b is connected form a clearance gap 4d, so that a wider connecting gap can be formed between the adsorption seats 4 after the adsorption seats 4 are turned. When the driving rod 7 passes the protruding part 3a on the cam 3 to form an axial sliding movement, the annular stop part 7b on the driving rod 7 extrudes the reset spring 8 to abut against the annular abutting part 10 on the corresponding half wheel body, so that the driving rod 7 can always keep in contact with the surface of the cam 3 regardless of whether it passes the protruding part 3a on the cam 3.

[0048] Specifically, referring to Figure 1 , the right end surface of the right cam 3 is eccentrically fixed with a mounting bracket 12, and the mounting bracket 12 is fixed with a support column 13. In use, the cigarette separating wheel assembly is mounted on the rack of a cigarette making machine, the left cam 3 and the support column 13 are fixed with the rack respectively, and the rack is further provided with a rotatable rotating shaft. The rotating shaft passes through the center of the left cam 3 and is fixed with the right half wheel body 2 after passing through the left half wheel body 1. When the rotating shaft rotates, it drives the left half wheel body 1 and the right half wheel body 2 to rotate, while the two cams 3 remain stationary due to being fixed with the rack, so that the driving rods 7 and the corresponding cams 3 have relative movement to realize the axial movement of the driving rods 7, so that the driving rods 7 can drive the transmission rod 5 to rotate under the action of the meshing tooth group, complete the turning of the adsorption seat 4, and drive the cigarette to turn.
