[0033] Please refer to the following: Figures 1 to 5This application provides a cigarette machine filter rod cutting device 100, which includes a cutting mechanism 10 and a drive mechanism 20 connected to the cutting mechanism 10. The cutting mechanism 10 and the drive mechanism 20 are configured to automatically feed and unload filter rods. The cutting mechanism 10 includes a housing 11, a rotating wheel 12, and a cutting blade assembly 13. The housing 11 includes a feeding channel 111. The rotating wheel 12 is at least partially disposed inside the housing 11, and the rotating wheel 12 cooperates with the feeding channel 111 to form a feeding space. 101. The rotating wheel 12 includes a body portion 121 having a first rotating shaft 1211, a first groove 122 and a second groove 123 disposed on the outer surface of the body portion 121. The first groove 122 is disposed along a first direction X, and the second groove 123 is disposed along the rotation direction of the body portion 121. The first direction X is parallel to the first rotating shaft 1211. The cutter assembly 13 is disposed downstream of the feed channel 111 along the rotation direction of the rotating wheel 12. The cutter assembly 13 cooperates with the second groove 123 and extends into the second groove 123.

[0034] The cigarette machine filter rod cutting device 100 is used to cut the filter rod to form multiple sub-filter rods of the same length. The sub-filter rods can be used directly in subsequent cigarette production and processing, or they can be used as samples to be tested to improve the consistency between different samples to be tested and reduce the impact of different physical parameters of different samples to be tested on the test structure.

[0035] The cutting mechanism 10 is the mechanism in the cigarette machine filter rod cutting device 100 that actually cuts the filter rod. The cutting mechanism 10 includes a housing 11, a rotating wheel 12, and a cutting blade assembly 13.

[0036] The outer casing 11 is the external component of the cutting mechanism 10, used to define the external contour of the cutting mechanism 10 and provide support or protection for the installation of the rotating wheel 12 and the cutter assembly 13. In these embodiments of the present application, the outer casing 11 can be a hollow structure to accommodate the rotating wheel 12 and the cutter assembly 13. In this case, the shape of the outer casing 11 can be set to match the rotating wheel 12 and the cutter assembly 13 to minimize the size of the hollow structure and thus reduce the footprint of the cutting mechanism 10.

[0037] The outer casing 11 includes a feeding channel 111, meaning that the outer casing 11 has at least one feeding channel 111, allowing the filter rods to be cut to be fed through the feeding channel 111. The feeding channel 111, together with the rotating wheel 12, forms a feeding space 101, meaning that one end of the feeding channel 111 points towards the rotating wheel 12, and the other end is connected to the outside. Thus, as the rotating wheel 12 rotates continuously, it can continuously feed the filter rods to be cut that are placed in the feeding space 101.

[0038] At least a portion of the rotor 12 is disposed within the housing 11. This means that in embodiments where the housing 11 has the aforementioned hollow structure, the rotor 12 can be disposed within the hollow structure, and the rotor 12, in conjunction with the feed channel 111, forms the feed space 101. Alternatively, in some embodiments, the housing 11 can be a non-enclosed structure. In this case, the housing 11 can be disposed at a point on the outer periphery of the rotor 12, and the feed channel 111 of the housing 11, in conjunction with the rotor 12, forms the feed space 101.

[0039] The rotating wheel 12 includes a body portion 121 having a first rotating shaft 1211, a first groove 122 and a second groove 123 provided on the outer surface of the body portion 121, wherein the body portion 121 is the main structural component of the rotating wheel 12 and is used to show the overall structural outline of the rotating wheel 12.

[0040] The main body 121 has a first rotating shaft 1211, which allows the main body 121 to rotate along the first rotating shaft 1211. By rotating the main body 121 along the first rotating shaft 1211, the outer contour of the rotating wheel 12 along the rotation direction can continuously change in the feeding space 101, thereby continuously driving the filter rod to be cut in the feeding space 101 to feed.

[0041] It is understood that in these embodiments of the present application, the first rotating shaft 1211 is located at the geometric center of the body portion 121 so that the rotating wheel 12 will not move radially when rotating, thereby improving the structural stability of the cutting mechanism 10.

[0042] The first groove 122 and the second groove 123 are provided on the outer surface of the main body 121. The first groove 122 is provided along the first direction X, and the second groove 123 is provided along the rotation direction of the main body 121. The first direction X is parallel to the first rotation axis 1211.

[0043] The first groove 122 is used for automatic feeding. When the filter rods to be cut are fed into the feeding space 101 by manual or external conveying mechanism, they will accumulate in the feeding space 101. At this time, as the rotating wheel 12 rotates continuously, the part of the filter rods in the feeding space 101 that is in contact with the rotating wheel 12 will adjust its own position according to the rotation of the rotating wheel 12, and finally make the filter rods stuck into the first groove 122. Under the drive of the first groove 122, they will follow the rotating wheel 12 to the next station (cutting assembly 13).

[0044] In these embodiments of the present application, the structure of the first groove 122 can be configured to match the filter rod to be cut, so that the first groove 122 can just accommodate one filter rod to be cut, so that the first groove 122 can drive one filter rod to be cut into position.

[0045] For example, in some embodiments, the feed channel 111 can be configured as a straight cylinder, with one end connected to the outside and the other end pointing towards the rotor 12. In this case, at the end of the feed channel 111 near the rotor 12, there is a gap between the feed channel 111 and the rotor 12, and the minimum value of this gap is less than the diameter of a single filter rod. Thus, when the filter rod in the feed space 101 is not engaged in the first groove 122, it will always be blocked by the wall structure of the feed channel 111 and cannot move forward with the rotor 12. However, when the filter rod is engaged in the first groove 122, the depth of the first groove 122 increases the gap between the body 121 and the feed channel 111. At this time, the filter rod engaged in the first groove 122 can rotate with the body 121 and move towards the cutter assembly 13.

[0046] The function of the second groove 123 is to avoid the cutter assembly 13. At this time, the second groove 123 is at least partially connected with the first groove 122, so that the blade structure in the cutter assembly 13 used for cutting can extend into the second groove 123, thereby cutting the filter rod stuck in the first groove 122.

[0047] The cutter assembly 13 is located downstream of the feed channel 111 along the rotation direction of the rotary wheel 12. This means that the cutter assembly 13 and the feed channel 111 are arranged sequentially around the periphery of the rotary wheel 12, and the feed channel 111 is located at the front end of the cutter assembly 13 along the rotation direction of the rotary wheel 12.

[0048] According to the embodiment of this application, the cigarette machine filter rod cutting device 100 is designed by arranging at least a portion of the rotating wheel 12 inside the housing 11, so that the rotating wheel 12 cooperates with the feeding channel 111 to form a feeding space 101, and by providing a first groove 122 on the outer surface of the main body 121, so that after the filter rod is placed into the feeding space 101, the rotation of the rotating wheel 12 can cause the filter rod to be inserted into the first groove 122, thereby realizing automatic feeding of the filter rod; at the same time, as the filter rod follows the rotation of the rotating wheel 12 in the first groove 122, when the filter rod rotates to the position of the cutting assembly 13, the cutting assembly 13 cooperates with the second groove 123 and extends into the second groove 123, thereby cutting and unloading the filter rod inserted in the first groove 122. In this way, the automatic feeding, cutting and unloading of the filter rod can be realized through the structural design of the rotating wheel 12, the housing 11 and the cutting assembly 13, so that the feeding and unloading process has higher working efficiency and reliability.

[0049] In some embodiments, the depth of the second groove 123 is not less than the depth of the first groove 122.

[0050] In these embodiments of this application, the depth between the first groove 122 and the second groove 123 can be designed to enable the cutting of different types of filter rods. For example, in some embodiments, the depth of the second groove 123 can be set to be no less than the depth of the first groove 122. In this case, after the cutting blade in the cutter assembly 13 extends into the second groove 123, it can completely cut the filter rod that is stuck in the first groove 122.

[0051] In some embodiments, the depth of the second groove 123 may be less than that of the first groove 122. In this case, after the cutting blade in the cutter assembly 13 extends into the second groove 123, it can partially cut the filter rod to form grooves on the filter rod, reduce the structural strength of the filter rod at the grooves, and then the filter rod can be divided by breaking it after processing.

[0052] In some embodiments, there are multiple first grooves 122, and the multiple first grooves 122 are evenly arranged along the rotation direction of the body portion 121.

[0053] In this way, as the main body 121 rotates continuously, different first grooves 122 can continuously enter and leave the feeding space 101, thereby improving the feeding speed and efficiency of the filter rod.

[0054] In some embodiments, the number of second grooves 123 is multiple; the cutter assembly 13 includes a second rotating shaft 131 and multiple cutting blades 132, the multiple cutting blades 132 are arranged sequentially at intervals along the axial direction of the second rotating shaft 131, and one cutting blade 132 is correspondingly arranged with one second groove 123.

[0055] The number of second grooves 123 is set to multiple, so that the cutter assembly 13 can be equipped with multiple blade structures to cut the filter rod at the same time, and then the filter rod can be divided into three, four or five sections in one cut.

[0056] The cutting blade 132 is a component in the cutting blade assembly 13 specifically used for cutting the filter rod, that is, the portion that at least partially extends into the second groove 123. In these embodiments of this application, multiple cutting blades 132 are arranged sequentially at intervals along the axial direction of the second rotating shaft 131, so that the second rotating shaft 131 can simultaneously drive multiple cutting blades 132 to rotate, thereby using the cutting edge of the cutting blade 132 located at the radial edge to cut the filter rod.

[0057] It should be noted that in these embodiments of this application, the spacing between adjacent cutting blades 132 is equal along the axial direction of the second rotation axis 131, so as to obtain multiple sub-filter rods of the same length when cutting the filter rod.

[0058] In these embodiments of the present application, the number of cutting blades 132 should not exceed the number of second grooves 123, so that each cutting blade 132 can cut the filter rod by extending into its corresponding second groove 123.

[0059] In some embodiments, the cigarette machine filter rod cutting device 100 further includes a negative pressure mechanism 30, which includes an exhaust fan 31 and an exhaust pipe 32 connected to the output end of the exhaust fan 31; the main body 121 includes a hollow space 1212 and a negative pressure channel 1213, one end of the negative pressure channel 1213 is connected to the hollow space 1212, and the other end penetrates the bottom surface of the first groove 122; the exhaust pipe 32 is connected to the hollow space 1212.

[0060] The main body 121 includes a hollow space 1212 and a negative pressure channel 1213, meaning that the main body 121 has a hollow structure so that the hollow space 1212 serves as the air passage for the negative pressure mechanism 30. One end of the negative pressure channel 1213 is connected to the hollow space 1212, and the other end penetrates the bottom surface of the first groove 122, so that the exhaust fan 31 can sequentially pass through the exhaust pipe 32, the hollow space 1212 and the negative pressure channel 1213 to form an air passage connecting to the bottom surface of the first groove 122, thereby creating a negative pressure environment at the bottom surface of the first groove 122.

[0061] In this way, after the filter rod is inserted into the first groove 122, the negative pressure environment formed by the negative pressure mechanism 30 on the bottom surface of the first groove 122 can adsorb the filter rod, thereby improving the stability of the filter rod inserted into the first groove 122, reducing the risk of the filter rod coming loose after being inserted into the first groove 122, and improving the stability of the filter rod when the cutter assembly 13 cuts the filter rod.

[0062] In some embodiments, the cigarette machine filter rod cutting device 100 further includes a feeding assembly 40, which is disposed downstream of the cutter assembly 13 along the rotation direction of the rotating wheel 12; the rotating wheel 12 further includes a third groove 124, which is disposed along the rotation direction of the body portion 121, and the third groove 124 is offset from the second groove 123 along the first direction X, and the feeding assembly 40 cooperates with the third groove 124 and extends into the third groove 124.

[0063] In some embodiments of this application, the feeding channel 111 can be positioned at the top of the rotating wheel 12, and the cutter assembly 13 can be positioned on the side of the rotating wheel 12. In this way, at the feeding space 101, the opening end of the first groove 122 faces upward. The filter rod in the feeding space 101 is inserted into the first groove 122 under the action of gravity and the rotation of the rotating wheel 12, and moves to the side of the rotating wheel 12 as the rotating wheel 12 rotates. After the cutter assembly 13 cuts the filter rod, the cut filter rod continues to rotate with the rotating wheel 12. When it rotates to the bottom position of the rotating wheel 12, the opening direction of the first groove 122 faces downward. At this time, the cut filter rod can be released from the first groove 122 under the action of gravity, realizing automatic feeding.

[0064] The function of the feeding component 40 is to assist in the feeding of the filter rod, helping the cut filter rod to detach from the first groove 122, thus achieving automated feeding. In these embodiments of this application, since the filter rod is adsorbed on the bottom surface of the first groove 122 by the negative pressure mechanism 30, a third groove 124 is provided on the rotating wheel 12. The feeding component 40 cooperates with the third groove 124 and extends into the third groove 124, so that after the cut filter rod rotates to the position of the feeding component 40, it can detach from the first groove 122 under the action of the part of the feeding component 40 extending into the third groove 124.

[0065] The third groove 124 and the second groove 123 are offset along the first direction X to reduce mutual interference between the cutter assembly 13 and the feeding assembly 40. At the same time, the offset third groove 124 and the second groove 123 make the part of the feeding assembly 40 that extends into the third groove 124 offset from the cutter 132 in the first direction X. This allows the feeding assembly 40 to feed the filter rod from a position close to the center of the filter rod when it acts on the cut filter rod. This makes it easier for the filter rod to detach from the first groove 122 and also reduces the risk of damage to the filter rod during the feeding process.

[0066] In some embodiments, there are multiple third grooves 124 and second grooves 123, and the third grooves 124 and second grooves 123 are staggered in the first direction X.

[0067] In these embodiments of the present application, the number of third grooves 124 matches the number of second grooves 123 so that each cut sub-filter rod can be fed by the feeding assembly 40.

[0068] It should be noted that in these embodiments of this application, the number of third grooves 124 should match the number of cut sub-filter rods.

[0069] For example, in an embodiment where there are two second grooves 123, i.e., two cutting blades 132 cut the filter rod, the number of sub-filter rods formed after cutting should be three. In this case, the number of third grooves 124 can be set to three. Other embodiments are similar and will not be described in detail.

[0070] In some embodiments, the unloading assembly 40 includes a guide slide 41 and an unloading block 42, the unloading block 42 being connected to the guide slide 41, and at least a portion of the unloading block 42 extending into the third groove 124.

[0071] The guide slide 41 is a component in the feeding assembly 40 used to concentrate the sub-filter rods. It is used to gather the sub-filter rods after feeding. That is, after the feeding assembly 40 feeds the sub-filter rods adsorbed in the first groove 122, each sub-filter rod can fall on the guide slide 41 and finally concentrate at the end of the guide slide 41.

[0072] The feeding block 42 is the portion of the aforementioned feeding assembly 40 that extends into the third groove 124. It is used to feed the sub-filter rods adsorbed in the first groove 122 into the third groove 124 when the rotating wheel 12 rotates. In these embodiments of this application, the feeding block 42 can be configured as a hook.

[0073] In some embodiments, the drive mechanism 20 includes a drive wheel 21, a first driven wheel 22, and a second driven wheel 23. The drive wheel 21 and the first driven wheel 22 cooperate with each other, and the first driven wheel 22 can rotate with the drive wheel 21. The second driven wheel 23 cooperates with the first driven wheel 22, and the second driven wheel 23 can rotate with the first driven wheel 22. The first driven wheel 22 is connected to the cutter assembly 13, and the second driven wheel 23 is connected to the first rotating shaft 1211.

[0074] The drive wheel 21 cooperates with the first driven wheel 22, and the second driven wheel 23 cooperates with the first driven wheel 22, so that the first driven wheel 22 can rotate with the drive wheel 21 and the second driven wheel 23 can rotate with the first driven wheel 22. That is, the drive mechanism 20 is a linkage structure composed of the drive wheel 21, the first driven wheel 22 and the second driven wheel 23. In this way, the drive wheel 21 can drive the first driven wheel 22 and the second driven wheel 23 to rotate synchronously.

[0075] In some embodiments of this application, the drive wheel 21, the first driven wheel 22, and the second driven wheel 23 can all be gears, so that the drive wheel 21 and the first driven wheel 22 cooperate with each other, and the second driven wheel 23 and the first driven wheel 22 cooperate with each other. In some embodiments, the drive wheel 21, the first driven wheel 22, and the second driven wheel 23 can all be belt pulleys, and the three can be linked together by a belt.

[0076] The first driven wheel 22 is connected to the cutter assembly 13, meaning that the first driven wheel 22 is connected to the second rotating shaft 131 in the cutter assembly 13, so as to drive the second rotating shaft 131 to rotate axially; at the same time, the second driven wheel 23 is connected to the first rotating shaft 1211, so as to drive the first rotating shaft 1211 to rotate. In this way, the drive wheel 21 drives the rotating wheel 12 and the cutter 132 to rotate synchronously, realizing automatic loading and unloading and automatic cutting.

[0077] In some embodiments, the cigarette filter rod cutting device 100 further includes a processing table 50, which includes a substrate 51 and a receiving assembly 52. ​​The substrate 51 is connected to the cutting mechanism 10 and the driving mechanism 20 respectively, and is provided with a feeding groove 511, which is provided through the substrate 51 along the thickness direction of the substrate 51. The receiving assembly 52 includes a slide rail 521 and a storage box 522. The slide rail 521 is provided on the surface of the substrate 51 away from the cutting mechanism 10. One end of the storage box 522 is open, and the open end of the storage box 522 is slidably engaged with the slide rail 521. When the storage box 522 is connected to the slide rail 521, the storage box 522 covers the feeding groove 511, and the open end of the storage box 522 is connected to the feeding groove 511.

[0078] The processing table 50 serves as a support, acting as the base platform for the cigarette machine filter rod cutting device 100.

[0079] The substrate 51 is a plate-shaped component in the processing table 50 specifically used to support the cutting mechanism 10 and the driving mechanism 20. The substrate 51 is provided with a feeding groove 511, which is provided through the substrate 51 along the thickness direction. This means that one side surface of the substrate 51 along the thickness direction can be used to support the aforementioned cutting mechanism 10 and driving mechanism 20, while the other side can be used to accommodate the cut sub-filter rods. The feeding groove 511 is a through-slot structure that connects the processing surface side of the substrate 51 where the cutting mechanism 10 and driving mechanism 20 are provided with and the receiving side for accommodating the cut sub-filter rods.

[0080] The function of the receiving component 52 is to collect and accommodate the cut sub-filter rods. In these embodiments of this application, the receiving component 52 includes a slide rail 521 and a storage box 522. The slide rail 521 is disposed on the surface of the substrate 51 away from the cutting mechanism 10. One end of the storage box 522 is open, and the open end of the storage box 522 is slidably engaged with the slide rail 521. When the storage box 522 is connected to the slide rail 521, the storage box 522 covers the discharge slot 511, and the open end of the storage box 522 communicates with the discharge slot 511, so that the receiving component 52 forms a storage structure similar to a drawer.

[0081] When the storage box 522 is connected to the slide rail 521, the cut sub-filter rods can fall into the storage box 522 through the feeding groove 511 for storage. When the storage box 522 is full, it can be pulled out through the slide rail 521 and a new storage box 522 can be used to store the cut sub-filter rods.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
