DETAILED DESCRIPTION

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present application and the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without paying any creative labor, and other embodiments can also be obtained. In addition, the design orientation belongs to only represent the relative position relationship between the components, not the absolute position relationship.

[0029] Please refer to Figure 5 , the structure diagram of the window cigarette 8, the window cigarette 8 includes the conventional tobacco segment 81 and the filter rod 82 carrying the transparent window. Generally speaking, the middle part of the filter rod 82 is the location of the transparent window, which is not wrapped with tipping paper during the tipping, that is, the location of the transparent window corresponds to the tipping space of the tipping paper (in order to form a transparent window at this location, the tipping paper is not wrapped at this location); the structure of the filter rod 82 is in turn the first segment 821 near the mouth, the transparent window segment 822, and the second segment 823 abutting the tobacco segment 81, wherein the first segment 821 and the second segment 823 are conventional filter rods, and the window segment 822 is the bursting bead 83. The window segment 822 is wrapped with plastic or other transparent material during tipping, and is fixed with the filter rods on both sides, thereby forming a transparent window. Through the transparent window, the internal bursting bead 83 can be observed at 360°, which facilitates the visual detection of the filling result of the bursting bead 83 and ensures the quality of the product.

[0030] On the basis of the existence of the tipping space, the single tipping paper is no longer suitable, and the single tipping paper 9 can be divided into multiple strips along the width direction, and the strip corresponding to the tipping space is removed, and the wrapping of the bursting bead 83 and the formation of the cigarette can be completed by tipping with the transparent tipping material.

[0031] It is not excluded that multiple burst beads 83 are arranged in the filter rod 82, and the multiple burst beads 83 can correspond to multiple independent window segments 822, and it is conceivable that more third segments and fourth segments of the filter rod structure are caused. Based on this, more strips of the cut paper are correspondingly cut from the single tipping paper 9, and the cut paper corresponding to the crimping space is removed.

[0032] The embodiment of the present application provides a cutting device for window cigarette tipping paper, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , mainly comprising a cutting assembly 4 and a guide assembly 5 arranged on a running path of the tipping paper, the cutting assembly 4 comprises parallel cutting knife groups, and the cutting direction of each cutting knife in the cutting knife group is consistent with the running direction of the tipping paper; the guide assembly 5 comprises a cutting plate 51 and a guide strip 53, the guide strip 53 is arranged at the front end of the cutting plate 51, the guide strip 53 is provided with a positioning gap, and a plurality of parallel cutting hole groups are arranged on the cutting plate 51 behind the positioning gap.

[0033] The parallel spacing of the cutting hole groups and the cutting knife groups is matched, the cutting plate 51 is fixedly arranged on the cutting knife group, and the cutting knife group protrudes to the upper surface of the cutting plate 51 through the cutting hole group.

[0034] The tipping paper is led out from the positioning gap to the cutting knife group protruding from the cutting hole group, and the single tipping paper is cut into multiple tipping papers by the cutting knife group.

[0035] In the present application, the single tipping paper is cut into multiple tipping papers by the cutting device, and three strips are taken as an example for illustration, referring to Figure 4 、 Figure 5 The middle one of the cut papers corresponds to the window segment 822, that is, corresponds to the crimping space, so only the middle one of the cut papers needs to be removed without crimping, and the two cut papers on the two sides are normally crimped, so that a transparent window is formed at the window segment 822 of the window cigarette 8, and a 360° visible burst bead is formed.

[0036] In the present application, the tipping paper 9 has a certain tension when running, and the tipping paper 9 is cut into multiple cut papers by the protruding cutting knife group when running along the cutting plate 51. In order to ensure the stability of the tipping paper 9 when being cut, the tipping paper 9 is limited, so that the running track of the tipping paper 9 is stable when reaching the cutting knife group, and the stability during cutting and the accuracy of the size of each cut paper after cutting are ensured.

[0037] In the embodiment of the present application, the guide strip 53 is arranged on the cutting plate 51 to limit the tipping paper 9 before cutting, the guide strip 53 is arranged in front of the cutting knife group, and the tipping paper 9 passes through the guide strip 53 after being limited, and then passes through the cutting knife group to complete the cutting.

[0038] In one possible embodiment, the guide strip 53 can be arranged at the front end of the cutting plate 51, and the cutting knife group is arranged immediately behind the guide strip 53, so that the tipping paper 9 can be cut in a closer interval and in a correct direction after being positioned and limited by the guide strip 53, i.e. the cutting operation is performed in a state that the positioning and limiting effect of the guide strip 53 on the tipping paper 9 is still good.

[0039] It can be understood that if the cutting is performed at a position far away from the guide strip 53, the positioning and limiting effect of the guide strip 53 cannot be guaranteed, and in this case, the cutting operation will seriously affect the accuracy of the cutting size.

[0040] In the embodiment of the present application, the tipping paper 9 runs along the cutting plate 51 after passing the guide strip 53 and is cut by the cutting knife group arranged in parallel on the upper surface of the cutting plate 51; the cutting knife group and the cutting plate 51 can partially overlap, so that part of the cutting edges of the cutting knife group protrude to the upper surface of the cutting plate 51 to position and cut the tipping paper 9 just out of the guide strip 53.

[0041] In one specific embodiment, the direction of each cutting knife in the cutting knife group is consistent with the running direction of the tipping paper, so that the plurality of cutting knives can cut the single tipping paper 9 into a plurality of tipping papers, i.e. into a plurality of cut papers, and the cut papers corresponding to the rolling space can be removed to form a transparent window.

[0042] In the present application, each cutting knife in the cutting knife group is arranged in parallel, and the distance between the two cutting knives corresponding to the rolling space can be limited, which should be consistent with the width of the window section 822, so that the cut paper after cutting is consistent with the width of the window section 822, thereby forming a transparent window that meets the size requirements.

[0043] Parallel cutting hole groups can be arranged on the cutting plate 51 immediately behind the guide strip 53, and the parallel distance of the cutting hole groups matches the parallel distance of the cutting knife group, so that the cutting edges of the cutting knife group can protrude to the upper surface of the cutting plate 51 through the cutting hole groups to cut the tipping paper 9.

[0044] During assembly, the relative position relationship between the cutting plate 51 and the cutting knife group can be adjusted, so that the cutting knife group can just protrude from the cutting hole groups to cut the tipping paper 9 running on the cutting plate 51 after the guide strip 53.

[0045] In the embodiment of the present application, in order to ensure the positioning and limiting effect of the guide strip 53 on the tipping paper 9, a positioning gap is arranged in the guide strip 53, and the cutting hole groups can be arranged immediately behind the positioning gap, so that the protruding cutting edges of the cutting knife group are closer to the guide strip 53 to complete the cutting operation and ensure the accuracy of the cutting operation.

[0046] In one specific embodiment, a positioning gap is formed in the guide strip 53 along the running direction of the tipping paper, the height of the positioning gap is greater than the thickness of the tipping paper, and the width of the positioning gap is greater than or equal to the width of the tipping paper.

[0047] In another specific embodiment, referring to Figure 3 , the guide strip 53 comprises a first guide and a second guide, the first guide and the second guide are fixed on the cutting plate 51 in a superposed manner, the superposed distance between the first guide and the second guide is greater than or equal to the thickness of the tipping paper, and the superposed distance between the first guide and the second guide is the positioning gap.

[0048] In the above two embodiments, the height of the positioning gap is close to the thickness of the tipping paper, which ensures the smooth running of the tipping paper; the width of the positioning gap is close to the width of the tipping paper, which ensures the normal running of the tipping paper without translation and shaking, so as to limit the running position of the tipping paper by the size of the positioning gap, and ensure the accurate cutting position of the cutting knife.

[0049] For example, the height of the positioning gap can be adjusted to the thickness of the tipping paper + 0.5 mm; the width of the positioning gap can be the width of the tipping paper + 0.1 mm, which prevents the tipping paper from shaking back and forth during cutting, so as to facilitate the stable cutting of the tipping paper into three pieces of cutting paper with a specified width.

[0050] In the embodiments of the present application, the cutting knife group is in an exposed state, and a protective plate 52 can be arranged above the cutting plate 51, the distance between the protective plate 52 and the cutting plate 51 can be consistent with the overall thickness of the guide strip 53. The overall structure of the protective plate 52 can be the same as that of the cutting plate 51, and the protective plate 52 can completely cover the exposed area of the cutting knife group to shield and protect.

[0051] In one specific embodiment, the front end of the protective plate 52 is fixed on the guide strip 53, and the rear end of the protective plate 52 is suspended above the cutting hole group, shielding the cutting knife group below.

[0052] It can be understood that the distance between the cutting plate 51 and the protective plate 52 is limited, and foreign objects cannot be inserted, which can effectively reduce the risk of cutting and the risk of falling and hitting the knife group.

[0053] For example, the superposed distance can be implemented based on the protective plate 52 and the cutting plate 51, referring to Figure 3 , Figure 4 A fixed plate 512 can be arranged on the front end side of the cutting plate 51, and a mounting plate can be arranged on the front end side of the protective plate 52, the mounting plate and the fixed plate 512 are fixed in position, so that the protective plate 52 is suspended above the cutting plate 51; the first guide is arranged on the lower side of the front end of the protective plate 52, and the second guide is arranged on the upper side of the front end of the cutting plate 51, so that the first guide is superposed on the second guide and forms a superposed distance.

[0054] It can be understood that the mounting plate and the fixing plate 512 are fixed in alignment, which requires that both are on the same side, i.e. the mounting plate and the fixing plate 512 are on the same side, such as the mounting plate is on the left side of the front end of the protective plate 52, and the fixing plate 512 is on the left side of the front end of the cutting plate 51. Of course, if the size of the cutting plate 51 is large enough, the alignment and fixation can be achieved without being on the same side, so that the protective plate 52 is suspended above the cutting plate 51, especially above the hole group.

[0055] The stacking distance is the distance between the first guide and the second guide. The tipping paper 9 passes through the stacking distance and is drawn out above the hole group to continue running along the cutting plate 51, and then is cut by the cutting knife group.

[0056] Further, the protective plate 52 can be positioned and fixed above the cutting plate 51 by a telescopic structure to adjust the suspension height of the protective plate 52 relative to the cutting plate 51. The relative position of the cutting plate 51 and the cutting knife group is fixed, and the suspension height of the protective plate 52 is adjusted, so that the size of the stacking distance is adjusted.

[0057] In this application, please refer to Figure 1 The cutting assembly 4 and the guide assembly 5 can be fixed on the base plate 11. The base plate 11 carries the supply device 1 for supplying tipping paper 9, a guide wheel group, an adjusting device 3 for adjusting the running position of the tipping paper 9, a first guide wheel 2 and a second guide wheel 21 for guiding the tipping paper 9. The guide wheel group can realize the tensioning function and is arranged immediately after the supply device 1. The adjusting device 3 is arranged after the guide wheel group and is fixed on the separation support by adjusting bolts. By rotating the adjusting bolts, the tipping paper 9 can be moved in and out along the axial direction to ensure that the tipping paper is centered. The first guide wheel 2 is arranged after the adjusting device 3, and the second guide wheel 21 is arranged before the cutting device. Both are used to adjust the running direction of the tipping paper, so that the tipping paper enters the guide strip 53 with a suitable trajectory to realize tensioning first and cutting later. After the cutting is completed, a third guide wheel can be arranged after the cutting device to guide the tipping paper 9 into the next process.

[0058] The above front and rear positional relationship is based on the running trajectory of the tipping paper 9, and is not the actual spatial positional relationship.

[0059] In a specific embodiment, the adjusting device 3 can be composed of two paper guide blocks, a spring and an adjusting shaft. The gap between the two paper guide blocks is adjusted to be tipping paper + 0.5 mm, which can adjust tipping paper with a width of 60-70 mm to meet the needs of various brands.

[0060] In the embodiment of the present application, the slitting assembly 4 further comprises a shaft body and a mounting seat 45, the shaft body is vertically assembled on the base plate 11 through the mounting seat 45, and a group of parallel cutting knives is arranged on the shaft body; the front end of the cutting plate 51 is provided with a fixed part 54, the cutting plate 51 is fixedly installed on the base plate 11 through the fixed part 54, and the cutting hole group on the cutting plate 51 is matched with the cutting knife group on the shaft body in position, so that the cutting knife group protrudes to the upper surface of the cutting plate 51 through the cutting hole group.

[0061] Please refer to Figure 2 , the shaft body can be installed on the base plate 11 in a vertical posture through the mounting seat 45, a group of cutting knives is arranged in parallel on the shaft body, so that the cutting knives in the cutting knife group are in a parallel state, and the cutting direction is consistent with the running direction of the tipping paper, and only two cutting knives are needed to obtain three slitting papers. Of course, the positions of the two cutting knives should be adjusted according to actual needs to obtain three slitting papers meeting the size requirements.

[0062] On this basis, the front end of the cutting plate 51 can be provided with a fixed part 54, the fixed part 54 can be formed by extending downward from the front end structure, and there is a certain distance between the fixed part 54 and the base plate 11, so that after the cutting plate 51 is fixed on the base plate 11 through the fixed part 54, the cutting hole group formed on the main body structure of the cutting plate 51 can be matched with the cutting knife group in position, so that the cutting knife group protrudes to the upper surface of the cutting plate 51 through the cutting hole group.

[0063] For example, the mounting seat 45 can be a shaft sleeve, the front end of the shaft body is exposed outside the shaft sleeve to carry the cutting knife group, and the rear end of the shaft body is installed based on the shaft sleeve. At this time, the shaft body can be fixed, and only the fixed cutting knife group is used to complete the cutting with the running power of the tipping paper 9. Of course, the shaft body can also be rotating, and the cutting knife group is driven by the shaft body to complete the cutting.

[0064] In the present application, corresponding to three slitting papers, the cutting knife group can include a first cutting knife and a second cutting knife, the distance between the first cutting knife and the second cutting knife is the same as the window width of the windowed cigarette; the cutting hole group includes a first cutting hole and a second cutting hole, the distance between the first cutting hole and the second cutting hole is the same as the distance between the first cutting knife and the second cutting knife, so that the parallel distance of the cutting hole group and the cutting knife group is matched.

[0065] After the cutting plate 51 is installed on the base plate 11, the first cutting knife protrudes outward through the first cutting hole, and the second cutting knife protrudes outward through the second cutting hole, thereby forming a cutting effect on the tipping paper 9.

[0066] In a specific embodiment, the shaft body is a transmission shaft 44, the first cutting knife and the second cutting knife are all cutting circular knives 7, the transmission shaft 44 is rotatably arranged on the base plate 11 through the mounting seat 45, and the transmission shaft 44 is in transmission connection with the motor 6, so that the transmission shaft 44 drives the cutting circular knives 7 to rotate.

[0067] The rear end of the transmission shaft 44 can pass through the mounting seat 45, the base plate 11 to the rear side of the base plate 11, and the transmission roller 46 is mounted thereon, and a transmission relationship is established between the transmission roller 46 and the motor 6, that is, the plurality of cutting circular knives 7 mounted on the transmission shaft 44 can drive the plurality of cutting circular knives 7 to rotate to slit the tipping paper.

[0068] In the present application, in order to cut three slits of tipping paper meeting the size requirements, a spacer is arranged between the cutting knives to stabilize the spacing between the cutting knives, and the tipping paper can be accurately cut during cutting.

[0069] In a specific embodiment, when assembling the cutting knives on the shaft body, a ring-shaped outer spacer 43, a ring-shaped inner spacer 42 and a gland 41 can also be included, the front end of the shaft body is provided with a stop ring, the outer spacer 43, the first cutting knife, the inner spacer 42 and the second cutting knife are sequentially sleeved on the shaft body before the stop ring, and the gland 41 is mounted on the front end of the shaft body to press the outer spacer 43, the first cutting knife, the inner spacer 42 and the second cutting knife against the stop ring and fix them on the shaft body; the width of the inner spacer 42 is the same as the width of the window.

[0070] The stop ring can be in the same position as the left side starting point of the tipping paper, the width of the outer spacer 43 is the width of the left strip of the slitting paper, the width of the inner spacer 42 is the width of the middle strip of the slitting paper, the middle strip of the slitting paper needs to be separated and removed, and the right strip of the slitting paper corresponds to the tobacco segment, which can be adjusted according to the actual length of the tobacco segment.

[0071] It can be understood that the gland 41 can be fixed on the front end of the shaft body by screws, and the outer spacer 43 and the inner spacer 42 should be made of a material that is not easy to compress and deform, so that the spacing size of the cutting knives does not change when the gland 41 is pressed against the stop ring.

[0072] In the embodiment of the present application, the cutting circular knife 7 is the preferred embodiment, the cutting plate 51 can be located above the stop ring, the outer spacer and the inner spacer without contacting them, but should be arranged close to them, so that the outer ring knife edge of the cutting circular knife 7 can protrude to the upper surface of the cutting plate 51. When the cutting circular knife 7 rotates, there is also a risk of cutting at other positions, and a protective cover 71 can be provided at the lower part of the cutting circular knife 7 to cover the cutting circular knife 7 as much as possible together with the cutting plate 51.

[0073] As a feasible embodiment, the cutting plate 51 can be in a horizontal form.

[0074] As a preferred embodiment, an arc-shaped bend is arranged at the middle section of the cutting plate 51, and a cutting hole group is arranged in the area where the arc-shaped bend is located, which cooperates with the third guide wheel to adjust the running track of the tipping paper on the cutting plate 51, so that the tipping paper forms a tensioning effect at the bending part, and cooperates with the protruding cutting knife group to form a good slitting effect.

[0075] The cutting hole 511 opened on the cutting plate 51 should correspond to the cutting knife. When the cutting knife is two, the cutting hole group should also include two cutting holes 511, as shown in Figure 4 The parallel cutting knives can simultaneously cut the tipping paper, which can avoid tearing the tipping paper.
