DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0022] See also Figure 5 , is a structural diagram of a window cigarette 8, which includes a conventional tobacco segment 81 and a filter rod 82 with a transparent window. Generally speaking, the middle of the filter rod 82 is where the transparent window is located. No tipping paper is used for splicing at this location during splicing, that is, the transparent window corresponds to the splicing space of the tipping paper (if a transparent window is to be formed here, no tipping paper is used for splicing at this location). The structure of the filter rod 82 is sequentially a first segment 821 near the mouth, a transparent window segment 822, and a second segment 823 docking the tobacco segment 81, wherein the first segment 821 and the second segment 823 are both conventional filter rods, and the window segment 822 contains a popping bead 83. When splicing the window segment 822, a transparent plastic or the like is used for splicing, and the filter rods on both sides are docked and fixed to form a transparent window, through which the popping bead 83 inside can be observed 360°, which is convenient for visually detecting the filling result of the popping bead 83 and ensuring the quality of the product.

[0023] On the basis of the existence of splicing spaces, a single strip of tipping paper is no longer applicable. The single strip of tipping paper 9 can be divided into multiple strips along the width direction, and a strip of cut paper corresponding to the splicing space is removed, and splicing is performed with a splicing material of a transparent material to complete the wrapping of the popping beads 83 and the forming of the cigarettes.

[0024] It is not ruled out that the filter rod 82 is provided with multiple bursting beads 83, and the multiple bursting beads 83 may correspond to multiple independent window segments 822, so that the filter rod structure with more third and fourth segments is conceivable. Based on this, a single strip of tipping paper 9 is correspondingly cut into more strips of cut paper, and the cut paper corresponding to the splicing space is removed.

[0025] The embodiment of the present invention provides a cutting device for window cigarette tipping paper, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , mainly comprising a slitting assembly 4 and a guiding assembly 5 arranged on the running path of the tipping paper, the slitting assembly 4 comprising a parallel cutting knife group, the cutting direction of each cutting knife in the cutting knife group is consistent with the running direction of the tipping paper; the guiding assembly 5 comprises a cutting plate 51 and a guiding bar 53, the guiding bar 53 is arranged at the front end of the cutting plate 51, a positioning gap is set in the guiding bar 53, and a parallel cutting hole group is opened on the cutting plate 51 directly behind the positioning gap; The parallel spacing between the cutting hole group and the cutting knife group matches, and the cutting plate 51 is fixed on the cutting knife group, and the cutting knife group passes through the cutting hole group and protrudes to the upper surface of the cutting plate 51; 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.

[0026] In this application, a single strip of tipping paper is cut into multiple strips by a cutting device, and three strips are used as an example for illustration. Figure 4 , Figure 5 The middle piece of slit paper corresponds to the window segment 822, that is, corresponds to the splicing space. Therefore, it is only necessary to remove the middle piece of slit paper without splicing it, and splice the two slit papers on both sides normally, so that a transparent window can be formed at the window segment 822 of the window cigarette 8, and the bursting beads can be seen 360 degrees.

[0027] In the present application, the tipping paper 9 has a certain tension during operation. When the tipping paper 9 runs along the cutting plate 51, it is cut into a plurality of cut papers by the protruding cutting knife group. In order to ensure the stability of the tipping paper 9 when being cut, the tipping paper 9 can be limited so that the running trajectory of the tipping paper 9 when reaching the cutting knife group is stable and not easy to change, thereby ensuring the stability during cutting and the accuracy of the size of each cut paper after cutting.

[0028] In the embodiment of the present application, a guide bar 53 is provided on the cutting plate 51 to limit the positioning of the tipping paper 9 before cutting. The guide bar 53 is provided in front of the cutting knife group. After the tipping paper 9 passes through the limit of the guide bar 53, it immediately passes through the cutting knife group to complete the cutting.

[0029] In a feasible embodiment, the guide bar 53 may be disposed at the front end of the cutting plate 51, and the cutting knife assembly may be located immediately behind the guide bar 53, so that the tipping paper 9 can be cut at a closer spacing distance and in a positive direction after being positioned and restricted by the guide bar 53, that is, the cutting operation can be performed while the positioning and restricting effect of the guide bar 53 on the tipping paper 9 is still maintained in a good state.

[0030] It is understandable that if the cutting is performed at a position far away from the guide strip 53, the guiding and limiting effect of the guide strip 53 cannot be guaranteed to be effective, and the cutting in this case will seriously affect the accuracy of the cutting size.

[0031] In the embodiment of the present application, after the tipping paper 9 passes through the guide strip 53, it runs along the cutting plate 51 and is cut by a cutting knife group arranged in parallel on the upper surface of the cutting plate 51; there may be a partial overlap between the cutting knife group and the cutting plate 51, so that part of the blade of the cutting knife group protrudes to the upper surface of the cutting plate 51, and the tipping paper 9 that has just passed through the guide strip 53 is positioned and cut.

[0032] In a 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 multiple cutting knives can cut a single tipping paper 9 into multiple tipping paper, that is, cut it into multiple cut papers, and remove the cut papers corresponding to the splicing space to form a transparent window.

[0033] 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 splicing space can be limited. The distance between the two cutting knives should be consistent with the width of the window segment 822, so that the cut paper after cutting is consistent with the width of the window segment 822, thereby forming a transparent window that meets the production size requirements.

[0034] A parallel cutting hole group can be opened on the cutting plate 51 directly behind the guide strip 53, and the parallel spacing of the cutting hole group and the cutting knife group is matched, so that the blade of the cutting knife group can protrude through the cutting hole group to the upper surface of the cutting plate 51, thereby cutting the butt paper 9.

[0035] 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 pass through the cutting hole group to cut the tipping paper 9 behind the guide strip 53 running on the cutting plate 51.

[0036] In the embodiment of the present application, in order to ensure the positioning and limiting effect of the guide strip 53 on the binding paper 9, a positioning gap is set in the guide strip 53, and the cutting hole group can be arranged directly behind the positioning gap, so that the protruding blade of the cutting knife group is closer to the guide strip 53 to complete the slitting operation, thereby ensuring the accuracy of the slitting operation.

[0037] In a specific embodiment, a positioning gap is provided 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.

[0038] In another specific embodiment, see Figure 3 The guide strip 53 includes a first guide member and a second guide member, the first guide member and the second guide member are stacked and fixed on the cutting plate 51, the stacking distance between the first guide member and the second guide member is greater than or equal to the thickness of the tipping paper, and the stacking distance between the first guide member and the second guide member is a positioning gap.

[0039] In the above two embodiments, the height of the positioning gap is close to the thickness of the tipping paper, so as to ensure the smooth operation of the tipping paper; the width of the positioning gap is close to the width of the tipping paper, so as to ensure the normal operation of the tipping paper without translational shaking. The running position of the tipping paper is limited by the size of the positioning gap, so that the cutting position of the cutting knife is accurate.

[0040] Exemplarily, 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 tipping paper width + 0.1 mm to prevent the tipping paper from swinging back and forth during the cutting process, so as to stably cut the tipping paper into three slit papers of specified widths.

[0041] In the embodiment of the present application, the cutting blade assembly is exposed, and a protective plate 52 may be provided above the cutting plate 51, and the distance between the protective plate 52 and the cutting plate 51 may be consistent with the overall thickness of the guide strip 53. The overall structural orientation of the protective plate 52 may be the same as that of the cutting plate 51, and the protective plate 52 should completely cover the exposed area of ​​the cutting blade assembly for shielding and protection.

[0042] In a specific embodiment, the front end of the protection plate 52 is fixed on the guide bar 53, and the rear end of the protection plate 52 is suspended above the hole cutting group to shield the cutting knife group thereunder.

[0043] It can be understood that the distance between the cutting plate 51 and the protective plate 52 is limited, and foreign objects are not inserted, which can effectively reduce the risk of cuts and the risk of falling and hitting the knife group.

[0044] For example, the stacking spacing can be implemented based on the protection plate 52 and the cutting plate 51, see Figure 3 , Figure 4 A fixing plate 512 may be provided on the front end side of the cutting plate 51, and a mounting plate may be provided on the front end side of the protective plate 52. The mounting plate and the fixing plate 512 are aligned and fixed so that the protective plate 52 is suspended above the cutting plate 51. The first guide member is provided on the lower side of the front end of the protective plate 52, and the second guide member is provided on the upper side of the front end of the cutting plate 51, so that the first guide member is stacked on the second guide member and a stacking interval is formed.

[0045] It is understandable that the mounting plate and the fixing plate 512 are aligned and fixed, and they are required to be on the same side, that is, the mounting plate and the fixing plate 512 are located on the same side, such as the mounting plate is located on the left side of the front end of the protective plate 52, and the fixing plate 512 is located 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 fixing can be achieved on different sides, so that the protective plate 52 is suspended above the cutting plate 51, especially above the cutting hole group.

[0046] The stacking spacing is the spacing between the first guide and the second guide. The tipping paper 9 passes through the stacking spacing and is led out to the top of the cutting group and continues to run along the cutting plate 51, and is then cut by the cutting knife group.

[0047] Furthermore, the protective plate 52 can be positioned and fixed above the cutting plate 51 through 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 to adjust the size of the stacking spacing.

[0048] In this application, please refer to Figure 1 , the slitting assembly 4 and the guide assembly 5 can be fixed on the base plate 11. The base plate 11 carries a supply device 1 for supplying the tipping paper 9, a guide wheel group, an adjustment device 3 for adjusting the running position of the tipping paper 9, a first guide wheel 2 for guiding the tipping paper 9, and a second guide wheel 21. Among them, the guide wheel group can realize the tensioning function and is arranged immediately after the supply device 1. The adjustment 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 inward and outward along the axial direction to ensure that the tipping paper is centered. The first guide wheel 2 is arranged after the adjustment device 3, and the second guide wheel 21 is arranged before the slitting device. The two 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, realizing tensioning first and cutting later. After the slitting is completed, a third guide wheel can be arranged after the slitting device to guide the tipping paper 9 into the next process.

[0049] The above front-to-back positional relationship is based on the running track of the tipping paper 9 and is not an actual spatial positional relationship.

[0050] In a specific embodiment, the adjusting device 3 may be composed of two paper guide blocks, a spring, and an adjusting shaft. The gap between the two paper guide blocks is adjusted to tipping paper + 0.5 mm, and the tipping paper width can be adjusted to 60 mm-70 mm to meet the requirements of various brands.

[0051] In the embodiment of the present application, the slitting assembly 4 also includes a shaft body and a mounting seat 45. The shaft body is vertically assembled on the substrate 11 through the mounting seat 45, and a parallel cutting knife group is arranged on the shaft body; a fixing portion 54 is provided at the front end of the cutting plate 51, and the cutting plate 51 is fixedly mounted on the substrate 11 through the fixing portion 54, and the cutting hole group on the cutting plate 51 is aligned and matched with the cutting knife group on the shaft body, so that the cutting knife group protrudes through the cutting hole group to the upper surface of the cutting plate 51.

[0052] See also Figure 2 The shaft body can be mounted on the base plate 11 in a vertical posture through the mounting seat 45, and a cutting knife group is arranged on the shaft body in parallel, so that the cutting knives in the cutting knife group are in a parallel state, and their cutting direction is consistent with the running direction of the tipping paper, and only two cutting knives are needed to cut and obtain three cut paper strips. Of course, the positions of the two cutting knives should be adjusted according to actual needs to obtain three cut paper strips that meet the size requirements.

[0053] On this basis, a fixing portion 54 can be provided at the front end of the cutting plate 51. The fixing portion 54 can be formed by extending downward from the front end structure and is spaced a certain distance from the substrate 11. After the cutting plate 51 is fixed on the substrate 11 by the fixing portion 54, the cutting hole group opened on the main structure of the cutting plate 51 can be aligned and matched with the cutting knife group, so that the cutting knife group protrudes through the cutting hole group to the upper surface of the cutting plate 51.

[0054] For example, the mounting seat 45 can be a sleeve, the front end of the shaft body is exposed to the sleeve to carry the cutting knife group, and the rear end of the shaft body is installed based on the sleeve. In this case, the shaft body can be fixed, and the cutting is completed only by the running power of the tipping paper 9 and the fixed cutting knife group. Of course, the shaft body can also be a rotating type, and the shaft body drives the cutting knife group to complete the cutting.

[0055] In the present application, corresponding to the three strips of slitting paper, the cutting knife group may include a first cutting knife and a second cutting knife, and the spacing between the first cutting knife and the second cutting knife is the same as the window width of the window cigarette; the cutting hole group includes a first cutting hole and a second cutting hole, and the spacing between the first cutting hole and the second cutting hole is the same as the spacing between the first cutting knife and the second cutting knife, so that the parallel spacing of the cutting hole group and the cutting knife group matches.

[0056] After the cutting plate 51 is mounted on the base plate 11 , the first cutting blade is convex through the first cutting hole, and the second cutting blade is convex through the second cutting hole, thereby forming a cutting effect on the binding paper 9 . In a specific embodiment, the shaft is a transmission shaft 44, and the first cutting knife and the second cutting knife are both cutting circular knives 7. The transmission shaft 44 is rotatably arranged on the substrate 11 through a mounting seat 45. The transmission shaft 44 is connected to the motor 6 so that the transmission shaft 44 drives the cutting circular knife 7 to rotate.

[0057] 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 a transmission roller 46 is mounted thereon. A transmission relationship is established between the transmission roller 46 and the motor 6, which can drive the multiple cutting circular knives 7 carried on the transmission shaft 44 to rotate and cut the tipping paper.

[0058] In the present application, in order to cut out three slit papers that meet the size requirements, a spacer can be provided between the cutting knives to stabilize the spacing between the cutting knives so that the tipping paper can be accurately cut during cutting.

[0059] In a specific implementation, when assembling the cutting knife on the shaft body, it can also include an annular outer spacer 43, an annular inner spacer 42 and a pressure cover 41. A stop ring is provided at the front end of the shaft body. The outer spacer 43, the first cutting knife, the inner spacer 42 and the second cutting knife are sequentially mounted on the shaft body before the stop ring. The pressure cover 41 is installed at 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 onto 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.

[0060] Among them, the stop ring can be at the same position as the left starting point of the tipping paper, the width of the outer spacer 43 is the width of the slit paper of the left strip, and the width of the inner spacer 42 is the width of the slit paper of the middle strip. The slit paper of the middle strip needs to be separated and removed, and the slit paper of the right strip corresponds to the tobacco segment, which can be adjusted according to the actual length of the tobacco segment.

[0061] It is understandable that the pressure cover 41 can be fixed to the front end of the shaft body by screws, and the outer spacer 43 and the inner spacer 42 should be made of materials that are not easily compressed and deformed, so that when the pressure cover 41 is pressed against the stop ring, the spacing size of the cutting knife does not change.

[0062] In the embodiment of the present application, the circular cutting knife 7 is taken as a preferred embodiment, and 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 each other so that the outer ring blade of the circular cutting knife 7 can protrude to the upper surface of the cutting plate 51. When the circular cutting 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 circular cutting knife 7 to cover the circular cutting knife 7 as much as possible in cooperation with the cutting plate 51.

[0063] As a possible embodiment, the cutting plate 51 may be in a horizontal form.

[0064] As a preferred embodiment, an arc-shaped bend is provided in the middle section of the cutting plate 51, and a cutting hole group is provided in the area where the arc-shaped bend is located. In cooperation with the third guide wheel, the running trajectory of the tipping paper is adjusted on the cutting plate 51, so that the tipping paper forms a tensioning effect at the curved portion, and cooperates with the protruding cutting knife group to form a good slitting effect.

[0065] The cutting holes 511 on the cutting plate 51 should correspond to the cutting knives. When there are two cutting knives, the cutting hole group should also include two cutting holes 511. Figure 4 The parallel-arranged cutting knives can cut the tipping paper simultaneously and synchronously, thus avoiding tearing of the tipping paper.
