[0032] 5. The setting of the fixing assembly facilitates the detachable connection between the first hub sleeve and the second hub sleeve and the hub body, and facilitates the maintenance and replacement of the first hub sleeve and the second hub sleeve.

[0033] 6. By setting the pin hole, it is convenient to drive the positioning pin for positioning when the first hub sleeve and the second hub sleeve are installed with the hub body, and it is convenient to quickly align the ventilation holes of the first hub sleeve and the second hub sleeve with the ventilation holes of the hub body, and at the same time avoid deflection between the first hub sleeve and the second hub sleeve and the hub body, so that the shoulder can drive the second hub sleeve to rotate through the pin connection, and the second hub sleeve can drive the first hub sleeve to rotate through the pin connection.

[0034] 7.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present application. In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and devices known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the techniques, methods and devices should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments may have different values, and it should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings. Example 1

[0046] This embodiment provides an adsorption hub for cutting cigarette filter segments, comprising a hub body 1, characterized in that it also includes:

[0047] A hub sleeve, the hub sleeve is fixedly mounted on the hub body 1, and a plurality of cigarette rod grooves 2 matching the diameter of the cigarette rod are evenly spaced and distributed circumferentially on the circumferential outer surface of the hub sleeve;

[0048] The air distribution drum 3 is located in the inner ring of the hub body 1, and the diameter of the air distribution drum 3 matches the inner diameter of the hub body 1;

[0049] The gas distribution groove 4 is formed on the gas distribution drum 3, and the outer ring of the gas distribution drum 3 is divided into a shielding part 5 and an open part 6 by the gas distribution groove 4;

[0050] A driving assembly, wherein one end of the hub body 1 is fixedly provided with a driving assembly for driving the hub body 1 to rotate;

[0051] Each of the cigarette rod grooves 2 is connected to the hollow space of the hub body 1 through a plurality of vent holes 7 which are arranged side by side and penetrate through the hub sleeve and the hub body 1 .

[0052] In the present technical solution, when the cigarette rod needs to be divided into two from the filter section, the present invention needs to be installed with the cutting device first, both ends of the gas distribution drum 3 have openings, and after one end of the gas distribution drum 3 is located in the hub body 1, the other end of the gas distribution drum 3 is fixedly connected to the air extraction end 23, and the air extraction end 23 is an air extraction pump or other air extraction equipment, so that the other end opening of the gas distribution drum 3 is fixedly set on the air extraction end 23;

[0053] Then, the end of the hub body 1 away from the air distribution drum 3 is fixedly connected to the rotating shaft of the driving device 24 through the driving assembly. The driving device 24 can be a driving motor or a reducer connected to the driving motor.

[0054] After the gas distribution drum 3 and the hub body 1 are fixed in the cutting device in the above manner, the cutter 25 of the cutting device is located above the utility model, and the cigarette rod to be cut is located below the utility model (the method of installing the utility model in the cutting device is a prior art and will not be described in detail here);

[0055] When it is necessary to cut the cigarette rod, start the driving device 24 and the exhaust end 23, so that the driving device 24 drives the hub body 1 and the hub sleeve to rotate, and the exhaust end 23 sucks air from one end of the air distribution drum 3, so that the air distribution drum 3 is in a negative pressure state. Since the diameter of the air distribution drum 3 matches the inner diameter of the hub body 1, the inside of the hub body 1 is in a negative pressure state, and each of the cigarette rod grooves 2 and the hollow of the hub body 1 are connected through a plurality of vents 7 arranged side by side on the hub sleeve and the hub body 1, so that the vents 7 have a negative pressure state, so that the cigarette rod to be cut located below the hub sleeve is adsorbed into the cigarette rod groove 2 corresponding to the current position;

[0056] Since the hub sleeve is fixedly mounted on the hub body 1, and the air distribution drum 3 is fixedly connected to the air extraction end 23, the hub body 1 rotates and drives the hub sleeve to rotate, so that the cigarette rod groove 2 on the hub sleeve rotates counterclockwise on the air distribution drum 3 with the axis of the hub body 1 as the axis. Since the outer ring of the air distribution drum 3 is divided into a shielding part 5 and an open part 6 by the air distribution groove 4, when the vent hole 7 corresponds to the open part 6, the vent hole 7 will not be blocked and has negative pressure suction, and when the vent hole 7 corresponds to the shielding part 5, the vent hole 7 will be blocked by the shielding part 5 of the air distribution drum 3, so that the negative pressure suction in the air distribution drum 3 and the hub body 1 will not be transmitted to the vent hole 7;

[0057] When the vent hole 7 is located below the hub body 1 and rotated to the top of the hub body 1, the vent hole 7 will correspond to the open portion 6, so that the cigarette rod to be cut located below the hub sleeve is adsorbed into the cigarette rod groove 2 corresponding to the current position, and can be rotated to the top of the hub body 1 by the rotation of the hub sleeve, so that the cigarette rod is cut by the cutter 25 above the hub body 1, and the cut cigarette rod continues to rotate with the rotation of the hub sleeve;

[0058] When the cigarette rod groove 2 containing the severed cigarette rod rotates to the front side facing the hub body 1, the cigarette rod groove 2 containing the severed cigarette rod will correspond to the shielding part 5 of the gas distribution drum 3, so that the shielding part 5 of the gas distribution drum 3 blocks the air vent 7 at the cigarette rod groove 2 containing the severed cigarette rod, so that the air vent 7 at the cigarette rod groove 2 containing the severed cigarette rod is released from the negative pressure suction state, so that as the hub sleeve rotates, the severed cigarette rod falls from the cigarette rod groove 2 under its own weight.

[0059] Through this structural design, by setting the air distribution drum 3 to cooperate with the hub body 1, the hub sleeve, the cigarette rod groove 2 and the air vent 7, it is only necessary to process a single large-diameter through hole matching the diameter of the air distribution drum 3 in the hub body 1, and there is no need to process multiple air intake holes to cooperate with the air vent 7, which makes the processing difficulty lower and the processing speed faster. At the same time, after the debris generated during cutting blocks the air intake hole, it is also easy to clean up, and the debris can be cleaned into the air distribution drum 3 and quickly sucked out. At the same time, the air distribution drum 3 has an open area and a blocked area, which is convenient for switching whether the cigarette rod groove 2 has adsorption force by whether the air vent 7 corresponds to the open area or the blocked area when rotating with the hub body 1 and the hub sleeve. Example 2

[0060] This embodiment provides an adsorption hub for cutting cigarette filter segments, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] Furthermore, the driving component comprises:

[0062] A jacket 8 is fixedly provided on the right end surface of the hub body 1, the inner diameter of the clamping groove of the jacket 8 matches the right end opening of the hub body 1, and the jacket 8 is clamped by screws.

[0063] In the present technical solution, by providing a jacket 8, the driving shaft of the driving device 24 can be inserted into the clamping groove of the jacket 8, and then the jacket 8 can be locked by screws, so that the jacket 8 can clamp the driving shaft of the driving device 24, making it convenient for the driving shaft of the driving device 24 to drive the hub body 1 and the hub sleeve to rotate. At the same time, the driving shaft of the driving device 24 can block the clamping groove of the jacket 8 and the right end opening of the hub body 1 to avoid air pressure leakage. Example 3

[0064] This embodiment provides an adsorption hub for cutting cigarette filter segments, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] Furthermore, the hub sleeve is divided into a first hub sleeve 9 and a second hub sleeve 10, and the first hub sleeve 9, the second hub sleeve 10 and the hub body 1 are detachably connected via a fixing assembly.

[0066] In the present technical solution, the hub sleeve is divided into a first hub sleeve 9 and a second hub sleeve 10. Since the features on the hub sleeve are relatively complex, the split processing increases the yield rate and avoids the scrapping of the entire hub sleeve due to one-time processing. At the same time, after part of the first hub sleeve 9 or the second hub sleeve 10 is damaged, the first hub sleeve 9 or the second hub sleeve 10 can be replaced separately without replacing the entire hub sleeve. The hub sleeves of different specifications of the cigarette rod groove 2 can also be replaced according to the specifications of the cigarette rod. Example 4

[0067] This embodiment provides an adsorption hub for cutting cigarette filter segments, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] Furthermore, it also includes:

[0069] End face groove 11, the opposite end faces of the first hub sleeve 9 and the second hub sleeve 10 are both provided with end face groove 11, the end face groove 11 divides the right end face of the first hub sleeve 9 and the left end face of the second hub sleeve 10 into an inner ring end face 12 and an outer ring end face 13, the inner ring end face 12 of the first hub sleeve 9 is arranged in abutment with the inner ring end face 12 of the second hub sleeve 10, and the outer ring end face 13 of the first hub sleeve 9 is arranged at a distance from the outer ring end face 13 of the second hub sleeve 10.

[0070] In the present technical solution, since the end face groove 11 is provided, the end face groove 11 divides the right end face of the first hub sleeve 9 and the left end face of the second hub sleeve 10 into an inner ring end face 12 and an outer ring end face 13, and the outer ring end face 13 of the first hub sleeve 9 and the outer ring end face 13 of the second hub sleeve 10 are arranged at an interval, and the interval forms a cutting groove corresponding to the cutter 25, which is convenient for the cutter 25 to cut into the cutting groove and thus cut the cigarette rod in the cigarette rod groove 2. At the same time, after the relative end faces of the first hub sleeve 9 and the second hub sleeve 10 are butted, the end face grooves 11 of the first hub sleeve 9 and the second hub sleeve 10 will also form a chip collecting groove, so that the debris generated by the cutting will enter the cutting groove and then enter the chip collecting groove. The chip collecting groove is larger than the interval of the cutting groove, so that even if the debris enters the chip collecting groove, it will not immediately cause blockage and jam the cutter 25. When cleaning, it is only necessary to disassemble the first hub sleeve 9 and the second hub sleeve 10 to clean the inside. Example 5

[0071] This embodiment provides an adsorption hub for cutting cigarette filter segments, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] A fixing ring 16 is fixedly provided on the left end of the hub body 1 . The diameter of the fixing ring 16 is larger than the diameter of the retaining ring 15 . The fixing ring 16 is fixedly connected to the left end of the hub body 1 by screws. One end of the fixing ring 16 is disposed in contact with the first hub sleeve 9 .

[0076] In the present technical solution, when the first hub sleeve 9 and the second hub sleeve 10 are installed, the second hub sleeve 10 is first inserted toward the hub body 1, so that the retaining ring 15 of the second hub sleeve 10 moves toward the shaft shoulder until the retaining ring 15 of the second hub sleeve 10 is set in contact with the shaft shoulder, and then the first hub sleeve 9 is inserted, and the inner ring end face 12 of the first hub sleeve 9 is moved toward the inner ring end face 12 of the second hub sleeve 10 until the inner ring end face 12 of the first hub sleeve 9 is in contact with the inner ring end face 12 of the second hub sleeve 10, and then the fixing ring 16 is fixedly connected to the left end of the hub body 1, so that the fixing ring 16 presses the left end face of the first hub sleeve 9, thereby pressing the first hub sleeve 9 and the second hub sleeve 10 onto the hub body 1.

[0077] Through this structural design and the setting of the fixing component, the detachable connection between the first hub sleeve 9 and the second hub sleeve 10 and the hub body 1 is facilitated, and the maintenance and replacement of the first hub sleeve 9 and the second hub sleeve 10 are facilitated. At the same time, the setting of the shoulder 14 and the ring 15 facilitates the positioning of the first hub sleeve 9 and the second hub sleeve 10. Example 6
