[0029] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] In order to better meet market demand, the middle section of the existing cigarette filter is set as a transparent structure. There is no filter rod inside this position, and the outside is not covered with kraft paper. Instead, a hollow tube made of transparent material is set, so that smokers can watch the smoke from the transparent structure of the middle section when smoking the cigarette, thereby improving the smoking experience. This requires cutting and separating the kraft paper at the corresponding position in advance when producing cigarettes. The existing technology provides a three-section kraft paper guide rail, which has three sections of grooves 321 separated from each other for conveying kraft paper. When producing this type of cigarette, it is necessary to adjust the width of the guide rail in advance, and then place the cut and separated kraft paper on the guide rail and convey it to the cigarette making machine for wrapping. The guide rail for conveying kraft paper provided by the existing technology can only convey kraft paper that has been cut and separated, and cannot realize the integrated cutting, separation and conveying of the entire sheet of kraft paper. Therefore, a cutting and separation device is urgently needed to realize the integrated cutting, separation and conveying of kraft paper.

[0034] In this regard, this embodiment provides a cutting and separating device, which can also convey multiple sections of tipping paper at the same time and can also solve the above-mentioned problems.

[0035] like Figure 1-Figure 2 As shown, the cutting and separating device is installed on the cigarette making machine body and is used to cut and separate the tipping paper. The cutting and separating device includes a base plate 1, a first drive component 2, a cutting component and a separation component. The base plate 1 is fixedly connected to the cigarette making machine body and is configured to carry and transport the tipping paper. The first drive component 2 is arranged at one end of the base plate 1 and is configured to drive the tipping paper to be transported along a first transport direction. The first transport direction is as shown in FIG. Figure 2 and Figure 4 As shown in the path S1 in FIG. , the first drive assembly 2 includes a first drive shaft 21 and a first drive member 22, and the first drive member 22 is key-connected to the first drive shaft 21. A connection portion 11 is provided on both sides of one end of the substrate 1, and both ends of the first drive shaft 21 are rotatably connected to the connection portions 11 on both sides of one end of the substrate 1. The cutting assembly includes a blade 35, which penetrates the substrate 1 and is configured to cut the tipping paper. The separating assembly is disposed at the other end of the substrate 1 and is configured to separate and transport the cut tipping paper.

[0036] The entire sheet of tipping paper is driven by the first driving component 2 for transportation on the base plate 1, and is cut by the blade 35 on the cutting component when passing through the cutting component. The cut tipping paper is then transported to the separation component for separation, and further transported to the cigarette making machine for subsequent production operations. The separation device separates the tipping paper along the cutting position so that there is a certain distance between the separated tipping papers. This distance is the width of the transparent middle section of the filter tip, thereby meeting the integrated requirements of tipping paper cutting, separation and transportation for producing cigarettes with transparent middle section filters.

[0037] It should be noted that the first drive assembly 2 is driven by the power source of the cigarette making machine and the related transmission device. The specific structure of the transmission device is the existing technology in this field and will not be described here.

[0038] Optionally, a limit member 12 is fixedly mounted on the base plate 1 and connected to the base plate 1 via bolts. Two limit members 12 are provided, one on each side of the base plate 1. Slotted holes are provided on either side of the base plate 1, through which bolts pass to securely connect the limit members 12. The position of the limit members 12 ensures the accurate positioning of the tipping paper during transport. The slotted holes in the base plate 1 also allow for adjustable mounting positions of the limit members 12 on the base plate 1, enabling the cutting device to be adapted for cutting tipping paper of varying specifications.

[0039] Furthermore, if Figure 3 As shown, the cutting assembly also includes a flange 31, an adjustment shaft 32, and a mounting base 33. The flange 31 is fixedly connected to the cigarette making machine body, preferably by bolts. A groove 321 is provided at the end of the adjustment shaft 32. The groove 321 can be square, star-shaped, triangular, or hexagonal, preferably a hexagonal groove in this embodiment. The adjustment shaft 32 passes through the center hole of the flange 31 and is rotatably connected to the flange 31. The flange 31 provides support for the adjustment shaft 32, thereby ensuring its proper operation. The mounting base 33 is sleeved onto the adjustment shaft 32. The connection between the mounting base 33 and the adjustment shaft 32 can be a key connection or an interference fit. In this embodiment, the connection between the mounting base 33 and the adjustment shaft 32 is preferably a key connection. The blade 35 is fixedly connected to the mounting base 33, preferably by bolts. The cutting edge of the blade 35 faces the first conveying assembly, ensuring that the tipping paper is effectively cut by the blade 35 when it reaches the cutting edge of the blade 35.

[0040] Furthermore, if Figure 1-Figure 3 and Figure 5 As shown, the base plate 1 is provided with an adjustment slot 13, through which the blade 35 passes and is movable. The adjustment shaft 32 is rotated by means of the groove 321 at the end thereof, thereby driving the mounting base 33 to rotate along the axis of the adjustment shaft 32, thereby driving the blade 35 fixedly connected to the mounting base 33 to move within the adjustment slot 13 while changing the length of the blade 35 extending out of the adjustment slot 13, thereby achieving an adjustable cutting height of the blade 35.

[0041] Specifically, during cigarette production, two filters are typically produced per cycle. For ease of explanation, let's take a conventional filter as an example. After production, the length of a conventional filter is twice the actual length of the filter on the cigarette. After being cut in the middle, the filter is divided into two strips, each packaged onto different cigarettes. This means that the length of the filter produced in a single batch is twice the length of the filter actually packaged onto the cigarette, requiring a single equal division to obtain the filter that is actually packaged onto the cigarette. However, prior to division, the tipping paper for conventional filters remains in a single sheet, requiring no cutting. However, for filters with a transparent middle section, since this section does not require tipping paper, the corresponding portion of the middle section must be cut and separated before division to reserve the width of the transparent portion. It is understood that producing a filter with a transparent middle section requires cutting the tipping paper at two locations before division, dividing the entire sheet into three strips to meet the requirement of producing two filters with transparent middle sections simultaneously.

[0042] Alternatively, as Figure 3 As shown, there are two mounting seats 33, each of which is sleeved on and fixedly connected to the adjustment shaft 32. The two mounting seats 33 are spaced apart on the adjustment shaft 32, and a blade 35 is fixedly connected to each mounting seat 33. Two adjustment slots 13 are provided on the base plate 1, and the two blades 35 penetrate the corresponding adjustment slots 13 on the base plate 1. The cutting edges of the two blades 35 face the first drive assembly 2.

[0043] Specifically, if Figure 3 As shown, the cutting assembly also includes a spacer 34, which is sleeved on the adjustment shaft 32. The two ends of the spacer 34 respectively abut against the mounting seats 33. The length of the spacer 34 is the distance between the two mounting seats 33. To prevent the spacer 34 and the mounting seats 33 from moving axially on the adjustment shaft 32, the adjustment shaft 32 can be configured as a stepped shaft to constrain one end of one of the mounting seats 33. The spacer 34 is disposed between the two mounting seats 33, constraining the other end of one of the mounting seats 33 and one end of the other mounting seat 33. In other embodiments, a second spacer 34 is disposed between the other mounting seat 33 and the flange 31, with one end of the second spacer 34 abutting against the flange 31 and the other end abutting against the other end of the other mounting seat 33. By changing the lengths of the two spacers 34, the distance between the two mounting seats 33 can be changed, thereby meeting the need to provide a transparent portion at different positions in the middle section of the filter tip.

[0044] Optionally, the cutting assembly further includes a guard 36, which is disposed on the outer layer of the cutting assembly and covers the flange 31, the adjustment shaft 32, the mounting seat 33, the spacer 34, and the blade 35, thereby providing protection for the flange 31, the adjustment shaft 32, the mounting seat 33, the spacer 34, and the blade 35. The guard 36 includes a connecting tab 361, which secures the guard 36 to the cigarette making machine body.

[0045] Further, if Figure 4 As shown, the separation assembly includes a bracket 4 and a transmission unit. The bracket 4 is fixedly mounted on the cigarette making machine body. One end of the bracket 4 is connected to the other end of the base plate 1. The bracket 4 has a receiving groove 44, and the transmission unit is disposed in the receiving groove 44. The transmission unit includes a separation wheel assembly, which is configured to transport one of the cut tipping paper strips along a second transport direction. The second transport direction is as shown in FIG. Figure 4 The second conveying direction is set at an angle to the first conveying direction. The angle between the second conveying direction and the first conveying direction depends on the overall length of the separation wheel assembly and the width of the transparent middle section of the filter tip. Those skilled in the art can adjust the angle between the second conveying direction and the first conveying direction according to actual production needs.

[0046] Specifically, after the cutting device cuts the entire sheet of tipping paper into two strips, the first drive assembly 2 drives the tipping paper to the conveying unit. One strip of tipping paper is driven by the separation wheel assembly in the second conveying direction, while the other strip of tipping paper continues in the first conveying direction. This creates a certain distance between the two strips of tipping paper, which is the width of the transparent portion of the filter's middle section.

[0047] Optionally, the width of the accommodating groove 44 gradually decreases along the first conveying direction, and the separation wheel assembly is disposed within the accommodating groove 44, with both ends of the separation wheel assembly being rotatably connected to the bracket 4. In this embodiment, the accommodating groove 44 is shaped like a right-angled trapezoid, with its hypotenuse aligned with the second conveying direction. The separation wheel assembly includes a separation wheel 61 and a separation shaft 62, which are key-connected to the separation shaft 62. The two ends of the separation shaft 62 are respectively rotatably connected to the bracket 4. Since the separation shaft 62 is subjected to both axial and radial forces, in this embodiment, a centripetal bearing is provided at the position where the separation shaft 62 is rotatably connected to the bracket 4 to ensure stable operation of the separation wheel assembly.

[0048] Optionally, in order to ensure the separation effect, the axis of the separation shaft 62 has a certain angle with the horizontal plane. In this embodiment, the vertical position height of the connection point between the separation shaft 62 and the oblique side of the accommodating groove 44 is preferably higher than the vertical position height of the connection point between the separation shaft 62 and the straight side of the accommodating groove 44. When separating the tipping paper, since the separation shaft 62 is tilted, it plays a certain guiding role on the tipping paper, so that the efficiency of the tipping paper separation is higher. Correspondingly, the position height of the centripetal bearing on the bracket 4 is adjustable, so that the inclination angle of the separation shaft 62 can be adjusted to meet the needs of various separation working conditions.

[0049] Furthermore, to ensure the separation effect, the number of separation wheel groups can be set to 2 groups, 3 groups, 4 groups or 5 groups. In this embodiment, the number of separation wheel groups is preferably two groups, and both groups of separation wheel groups are arranged in the accommodating groove 44 and the two groups of separation wheel groups are arranged along the second conveying direction.

[0050] In other embodiments of the present invention, the separation wheel set can also be configured as a Mecanum wheel set, thereby achieving both forward and lateral transport. The use of a Mecanum wheel set to achieve directional transport and the method of configuring a Mecanum wheel set are both prior art in the art and will not be described in detail.

[0051] Furthermore, the bracket 4 further includes an adjustment member 43 fixedly mounted on a side of the bracket 4. The adjustment member 43 is configured to adjust the direction of transport of one of the cut tipping papers from the second transport direction to the first transport direction. Specifically, after one of the tipping papers is transported a certain distance in the second transport direction by the separation wheel assembly, the distance between the two tipping papers increases to the width of the transparent portion of the filter middle section. At this time, the adjustment member 43 changes the transport direction of one of the tipping papers from the second transport direction back to the first transport direction, i.e., the two tipping papers are transported in parallel at a predetermined distance.

[0052] Specifically, the adjustment member 43 is fixedly arranged on the side of the bracket 4 and the edge position of one side of the accommodating groove 44, and the first separator 41 is also provided on the edge position of the other side of the accommodating groove 44 on the corresponding bracket 4. The front end of the first separator 41 has a guide surface, and the rear end of the first separator 41 has an adjustment surface. The tipping paper is transported along the second conveying direction along the guide surface of the first separator 41. After passing through the adjustment member 43, the conveying direction of one of the tipping papers changes from the second conveying direction to the first conveying direction, and the two sides of the tipping paper are in contact with the side of the adjustment member 43 and the adjustment surface of the first separator 41 respectively, so that the width of the first separator 41 is the width of the transparent part of the middle section of the filter tip.

[0053] Optionally, the locations where the adjustment member 43 and the first separator 41 are connected to the bracket 4 are each provided with a position adjustment structure, so that the relative positions of the adjustment member 43 and the first separator 41 and the bracket 4 are adjustable to accommodate the separation and transportation of tipping paper of different widths after cutting by the cutting assembly. In this embodiment, the position adjustment structure can be a combination of a bolt and an elongated hole, or a combination of a bolt and multiple groups of connecting holes. The relevant arrangement and implementation principles are all prior art in the field and will not be described here. Those skilled in the art can determine the specific structure and arrangement of the position adjustment structure based on actual engineering practices.

[0054] Furthermore, the cutting and separating device also includes a second drive assembly 5, which is disposed at the other end of the bracket 4 and is configured to drive the cut tipping paper to be transported along the first conveying direction. The second drive assembly 5 includes a second drive shaft 51 and a second drive member 52, the second drive member 52 being key-connected to the second drive shaft 51, which is rotationally connected to the bracket 4. After the tipping paper is cut and separated, the two pieces of tipping paper are transported in parallel at a certain interval. At this time, since the tipping paper is far away from the first conveying unit, accumulation may occur due to untimely transportation. The provision of the second drive assembly 5 reduces the risk of tipping paper accumulation. At the same time, protrusions can be provided on the second drive member 52 to be equal to the width of the tipping paper and the distance between the two pieces of tipping paper, allowing the second drive assembly 5 to adjust the conveying state of the tipping paper, ensuring that the tipping paper entering the cigarette making machine meets production requirements.

[0055] It should be noted that the second drive assembly 5 is driven by the power source of the cigarette making machine and the related transmission device. The specific structure of the transmission device and the structure and method for realizing the synchronous driving of the first drive assembly 2 and the second drive assembly 5 are existing technologies in this field and will not be described here.

[0056] Optionally, an adjustment wheel assembly can be provided between the separation wheel assembly and the second drive assembly 5. The adjustment wheel assembly is disposed within the accommodating slot 44 and includes an adjustment wheel 63 and an adjustment shaft 64. The adjustment wheel 63 is keyed to the adjustment shaft 64, and both ends of the adjustment shaft 64 are rotatably connected to the bracket 4. The adjustment wheel assembly provides effective support for one of the tipping paper strips when changing the conveying direction, preventing deformation or bending of the tipping paper due to lack of support.

[0057] It should be noted that the above embodiment is aimed at the separation component for producing one filter tip at a time. For the case of producing two filter tips at a time, that is, the cutting device cuts the entire sheet of kraft paper into three strips, it is only necessary to mirror the structure of the above embodiment and correspondingly set the first separation component 41 to the second separation component 42, so it will not be described here.

[0058] This embodiment also provides a cigarette making machine, comprising a cigarette making machine body and a cutting and separating device according to an embodiment of the present invention. By providing the cutting and separating device according to an embodiment of the present invention, the cigarette making machine can realize the integrated cutting, separation and transportation of tipping paper.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
