Description

Technical Field

[0001] The invention relates to the technical field of tobacco production equipment, and in particular to a groove plate structure of a slitting hub wheel and a slitting hub wheel. Background Art

[0002] Filter rods are one of the important raw materials in the cigarette industry. During the production process of filter rods, it is usually necessary to cut the filter rods, cutting a double-length (or multiple-length) filter rod into two (or more) filter rods.

[0003] In the prior art, a slitting hub wheel is usually used in conjunction with a cutter to achieve slitting of filter rods. The slitting hub wheel adsorbs double-length (or multiple-length) filter rods in the filter rod groove on the outer periphery of the slitting hub wheel by negative pressure adsorption. The slitting hub wheel rotates to move the double-length (or multiple-length) filter rods to the position of the cutter, and then the cutter cuts the double-length (or multiple-length) filter rods on the slitting drum wheel to form multiple relatively short filter rods.

[0004] However, in the prior art, filter rods have a variety of different diameter specifications, and a slitting hub wheel can only be used with filter rods of one diameter specification, resulting in the need to use different slitting equipment when producing filter rods of different diameter specifications.

[0005] In addition, in the prior art, there is also a structure that can replace the bearing shells on the outer periphery of the slitting hub wheel. The filter rod grooves for accommodating filter rods are arranged on the bearing shells on the outer periphery of the slitting hub wheel, and the bearing shells are arranged in a variety of specifications. The size of the filter rod grooves on the bearing shells of one specification is designed for a filter rod of one diameter specification. When the production specification of the filter rod needs to be changed, the equipment is shut down and then the bearing shells on the slitting hub wheel are replaced, so that the slitting hub wheel can be adapted to the use of filter rods of another diameter specification. However, in the prior art, when replacing the bearing shells and other specification parts, a large number of structural parts need to be disassembled, the replacement cycle is long, the equipment downtime is long, and the operator's skills are required to be high. Summary of the invention

[0006] In view of the technical problems that when the production specifications of the filter rod are replaced in the prior art, the bearing needs to be replaced, and the replacement cycle is long, resulting in a long equipment downtime, affecting the production efficiency. In addition, the replacement of the bearing requires high skills of the operator and the replacement is difficult. The present invention provides a slot plate structure for a split hub wheel, which is provided with a fixed part and a movable part. The outer periphery of the fixed part is provided with a plurality of first sheets. The movable part is provided with a second sheet. The second sheet is inserted between the two first sheets. The edge of the second sheet and the edge of the first sheet together form a filter rod slot, and the movable part has a plurality of installation positions in the circumferential direction. When producing filter rods with different diameter specifications, it is only necessary to rotate and adjust the position of the movable part, so that the slot width of the filter rod slot can be adjusted accordingly to adapt to the production of filter rods with different diameter specifications. During the conversion process, there is no need to disassemble a large number of structural parts, so that the long equipment downtime can be reduced, the production efficiency can be improved, and the operation is simple, which reduces the skill requirements for the operator.

[0025] The present invention provides a slot plate structure of a slitting hub wheel, which comprises a slot plate and a filter rod slot and a cutting knife slot opened on the outer periphery of the slot plate; the slot plate comprises a fixing part and a movable part installed on the fixing part; a plurality of first sheets are sequentially arranged at intervals on the outer periphery of the fixing part; a plurality of second sheets are arranged on the movable part; a second sheet is arranged between each two adjacent first sheets, and the second sheet is spaced from the first sheet to form the filter rod slot; along the circumference of the slot plate, the movable part has a plurality of mounting positions on the fixing part. In the slot plate structure of the slitting hub wheel, the filter rod slot is formed by the first sheet and the second sheet being spaced from each other, and along the circumference of the slot plate, the movable part has a plurality of mounting positions on the fixing part, so that the spacing distance between the first sheet and the second sheet can be adjusted by adjusting the mounting position of the movable part on the fixing part along the circumference, thereby adjusting the slot width of the filter rod slot. When changing the production specifications of the filter rod, it is only necessary to adjust the installation position of the movable part to adaptively adjust the filter rod slot of appropriate slot width to adapt to the production of filter rods of different diameters. During the conversion process, there is no need to disassemble a large number of structural parts, thereby reducing equipment downtime and improving production efficiency. The operation is simple and the skill requirements for operators are reduced.

[0026] Please refer to Figures 1 to 3 In one embodiment, a slot plate structure 100 of a slitting hub wheel is provided, and the slot width of the filter rod slots provided therein can be adaptively adjusted, so that filter rods of different diameters can be adapted for production. The slot plate structure 100 of the slitting hub wheel is mainly used to solve the problem in the prior art that when changing production specifications, a large number of structural parts need to be disassembled and assembled, and the replacement cycle is long, resulting in a long equipment downtime and affecting production efficiency.

[0027] The slot plate structure 100 of the slitting hub wheel includes a slot plate 10 and a filter rod slot 20 and a cutter slot 30 opened on the outer periphery of the slot plate 10. The slot plate 10 includes a fixing member 11 and a movable member 12 installed on the fixing member 11. A plurality of first sheets 111 are sequentially arranged at intervals on the outer periphery of the fixing member 11, and a plurality of second sheets 121 are arranged on the movable member 12. A second sheet 121 is arranged between each two adjacent first sheets 111, that is, the second sheet 121 is inserted into the position area between two adjacent first sheets 111, and a second sheet 121 is inserted into the position area between each two adjacent first sheets 111, so that along the circumference of the slot plate 10, the distribution of each sheet is: the first sheet 111, the second sheet 121, the first sheet 111, the second sheet 121... The second sheet 121 is spaced apart from the first sheet 111 to form the filter rod slot 30. That is to say, the filter rod slot 30 is opened between the first sheet 111 and the second sheet 121, and the circumferential edge of the second sheet 121 and the circumferential edge of the first sheet 111 constitute a part of the filter rod slot 30, so that by adjusting the spacing distance between the second sheet 121 and the first sheet 111, the slot width of the filter rod slot 30 can be adjusted accordingly.

[0028] Along the circumference of the slot plate 10, the movable part 12 has a plurality of mounting positions on the fixed part 11. That is to say, there is not only one mounting position between the movable part 12 and the fixed part 11, but a plurality of mounting positions along the circumference. The relative position of the movable part 12 and the fixed part 11 can be adjusted by rotating the movable part 12 relative to the fixed part 11, and after the relative position is adjusted, the movable part 12 can still be mounted and fixed on the fixed part 11. Since the second sheet 121 is provided on the movable part 12, after adjusting the position of the movable part 12, the spacing distance between the second sheet 121 and the first sheet 111 can be adjusted synchronously, thereby correspondingly adjusting the slot width of the filter rod slot 30, so that the slot plate structure 100 of the slitting hub wheel can be adapted to the production of filter rods of different diameters.

[0029] It is understandable that filter rods currently have many different specifications. For commonly used filter rods that need to be produced, there are currently roughly 19 types of rod material numbers for filter rods. The specific parameters are shown in Table 1 below.

[0030] Table 1 Filter rod cutting parameters

[0031] At present, there are four diameters of conventional filter rods. In the prior art, each diameter of the filter rod usually has a corresponding bearing. When producing filter rods of different diameters, it is necessary to replace the bearing on the periphery of the slitting hub wheel and install the bearing corresponding to the required filter rod diameter on the periphery of the slitting hub wheel to achieve the slitting production of the filter rod. However, when replacing the bearing and other specification parts, a large number of structural parts need to be disassembled, the replacement cycle is long, the equipment downtime is long, and the operator's skills are required to be high. In the slot plate structure 100 of the slitting hub wheel provided in the present embodiment, the filter rod slot 20 is enclosed by the second sheet 121 on the movable part 12 and the first sheet 111 on the fixed part 11. When the production specification needs to be changed, it is only necessary to adjust the installation position of the movable part 12 on the fixed part 11 to adjust the slot width of the filter rod slot 20 to the required width, so that filter rods of different diameters can be adapted for production. For example, when it is necessary to change the production of a filter rod with a larger diameter, the second sheet 121 can be adjusted away from the first sheet 111, so that the slot width of the filter rod slot 20 can be increased, so as to adapt to the production of filter rods with a larger diameter; and when it is necessary to change the production of a filter rod with a smaller diameter, the second sheet 121 can be adjusted toward the first sheet 111, so that the slot width of the filter rod slot 20 can be reduced, so as to adapt to the production of filter rods with a smaller diameter. When changing the production specifications, the slot plate structure 100 of the slitting hub wheel does not require overall replacement of components, nor does it require disassembly of a large number of structural parts. It only requires rotation and adjustment of the position of the movable part 12, thereby correspondingly adjusting the slot width of the filter rod slot 20 to accommodate the production of filter rods of different diameters. This can reduce equipment downtime, improve production efficiency, and is simple to operate, reducing the skill requirements for operators.

[0032] Preferably, in one embodiment, the first sheets 111 on the outer circumference of the fixing member 11 are evenly spaced, that is, on the fixing member 11, the spacing between each two adjacent first sheets 111 is equal, so that the first sheets 111 arranged on the fixing member 11 are evenly spaced as a whole. The movable member 12 includes a mounting portion 122 and a second sheet 121, the mounting portion 122 is mounted on the fixing member 11, and the second sheet 121 is arranged on the mounting portion 122. Along the circumference of the slot plate 10, the second sheets 121 on the mounting portion 122 are evenly spaced, and similarly, on the mounting portion 122, the spacing between each two adjacent second sheets 121 is also equal. By arranging each of the first sheets 111 and each of the second sheets 121 at even intervals, a plurality of filter rod slots 20 with the same slot width are formed on the slot plate 10, and after the mounting position of the movable part 12 is adjusted by rotation, the slot width of each filter rod slot 20 also changes synchronously, so that during each processing, a plurality of filter rod slots 20 can be used on the slot plate 10, thereby improving processing efficiency.

[0033] It is understandable that the two sides of a second sheet 121 will respectively form two filter rod slots 20 with two adjacent first sheets 111. When the second sheet 121 is not in the exact center between the two first sheets 111, the slot widths of the filter rod slots 20 on both sides will be different. Therefore, in actual processing, only the filter rod slots 20 on one side will be used. That is to say, in this case, the filter rod slots 20 that can be used for filter rods on the slot plate structure 100 of the cutting hub wheel are only half of the actual number of slots. Of course, when the second sheet 121 is in the exact center between the two first sheets 111, the slot widths of the filter rod slots 20 on both sides will be the same. Therefore, in actual processing, the filter rod slots 20 on both sides can be used.

[0034] The slot plate structure 100 of the slitting hub wheel adopts a nested structure, and the filter rod slot 20 for accommodating the filter rod is opened between the fixed part 11 and the movable part 12, and filter rods of various diameters are clamped by rotating the movable part 12. Specifically, when the fixed part 11 and the movable part 12 are slotted, they are slotted according to the minimum filter rod diameter required for production. For the currently common filter rod specifications, the fixed part 11 and the movable part 12 are slotted based on the minimum diameter of the filter rod of 5.4 mm.

[0035] Preferably, in one embodiment, a plurality of the knife grooves 30 are provided along the circumference of the slot plate 10, and the knife grooves 30 are spaced apart from each other, and each filter rod slot 20 is provided with the knife groove 30. The knife groove 30 is mainly used to avoid the cutter, and when the cutter cuts the filter rod, the cutter can extend into the knife groove 30 to ensure that the cutter cuts the filter rod. It is understandable that the knife grooves 30 in the prior art are usually distributed in a ring shape on the bearing. In this embodiment, the knife grooves 30 are not an integral annular structure, but are distributed in sequence at intervals along the circumference of the slot plate 10, and each filter rod slot 20 is provided with the knife groove 30. It can be understood that, since in this embodiment, the cutting knife grooves 30 are not distributed in a ring shape, in order to avoid the cutting knife cutting other parts of the groove plate 10, intermittent processing can be adopted during processing. When one of the filter rod grooves 20 drives the filter rod to the cutting station, the slitting hub wheel stops rotating, and the cutter then extends into the filter rod groove 20 to cut the filter rod. After the cutting is completed, after the cutter is retracted, the slitting hub wheel rotates again to drive the next filter rod groove 20 to the cutting station.

[0036] It should be noted that the lengths required for slitting filter rods of various specifications are not the same, so the axial positions of the cutting grooves opened on the bearings of various specifications in the prior art will also be different. Since the slot plate structure 100 of the slitting hub wheel needs to be adapted to filter rods of various specifications for use, it is necessary to concentrate multiple cutting grooves at different positions on the slot plate 10, and there will be some problems at this time. For example, the axial spacing between some adjacent cutting grooves is too small, making it difficult to ensure processing accuracy; at the same time, the cutting grooves of filter rods of different specifications may overlap, resulting in the cutting grooves being too wide, which in turn causes the rod material to bend and deform during the cutting process. By arranging a plurality of the cutting grooves 30 spaced apart from each other along the circumferential direction, the arrangement of the cutting grooves 30 can be facilitated, and the cutting grooves 30 at different positions can be opened on different filter rod slots 20, so that filter rods of different specifications can be better adapted for use.

[0037] Preferably, in one embodiment, a plurality of the cutting grooves 30 are distributed at each of the filter rod slots 20, and the cutting grooves 30 are spaced apart from each other along the axial direction of the slot plate 10. That is to say, in this embodiment, there are a plurality of the cutting grooves 30 at one of the filter rod slots 20, and the plurality of the cutting grooves 30 distributed on this filter rod slot 20 are spaced apart from each other along the axial direction. Through this structure, one of the filter rod slots 20 can be adapted to filter rods of various specifications for use, thereby further improving processing efficiency. It should be noted that when the axial spacing between the cutting grooves 30 to be opened is too close, in order to avoid too small a spacing or overlap between the two, one of the cutting grooves 30 can be opened at another of the filter rod slots 20 to avoid affecting the processing of the rod material.

[0038] Preferably, in one embodiment, the cutting groove 30 includes a first groove body 31 and a second groove body 32 adapted to the first groove body 31, the first groove body 31 is opened on the circumferential edge of the first sheet body 111 and the outer periphery of the fixing member 11, and the second groove body 32 is opened on the circumferential edge of the second sheet body 121. That is to say, in this embodiment, a complete cutting groove 30 is composed of the first sheet body 111, the second sheet body 121, and the groove body on the fixing member 11, so that it can better adapt to filter rods of different specifications for use.

[0039] Preferably, in one embodiment, the first grooves 31 are provided on both sides of the first sheet 111, and the second grooves 32 are provided on both sides of the second sheet 121. That is, in this embodiment, the first grooves 31 are provided on both sides of the first sheet 111, so that the cutting grooves 30 can be formed on both sides. Similarly, the second grooves 32 are provided on both sides of the second sheet 121, so that the cutting grooves 30 can be formed on both sides.

[0040] Preferably, in one embodiment, along the circumference of the slot plate 10, a plurality of (at least two) filter rod slots 20 sequentially distributed form a group of filter rod slot groups 200, and the positions of the cutting grooves 30 distributed on the filter rod slots 20 in each group of the filter rod slot groups 200 are different. In other words, a plurality of adjacent filter rod slots 20 can be grouped together, and the positions of the cutting grooves 30 opened on the filter rod slots 20 in the group of the filter rod slot groups 200 are not the same, so that different filter rod slots 20 in the filter rod slot group 200 can be adapted to filter rods of different specifications for cutting and use.

[0041] Please refer to Figure 4 , for example, in Figure 4In the embodiment shown, each of the four adjacent filter rod slots 20 can be divided into a group of filter rod slot groups 200. For the convenience of description, the four filter rod slots 20 in a group of filter rod slot groups 200 are sequentially divided into work station numbers: 1, 2, 3, and 4. The positions of the cutting grooves 30 specifically distributed on the filter rod slots 20 corresponding to each work station number are different, so that the filter rod slots 20 of each work station number can correspond to at least one specification of filter rods for production and use. Among them, the different positions of the cutting grooves 30 distributed on each filter rod slot 20 in each group of filter rod slot groups 200 means that the cutting grooves 30 distributed on each filter rod slot 20 are completely different or partially different. In other words, there will be no situation where the distribution of the cutting grooves 30 is completely consistent in each filter rod slot 20 in a group of filter rod slot groups 200.

[0042] Please refer to Figure 4 and Figure 5 . Preferably, in one embodiment, the filter rod slot groups 200 are sequentially distributed in a plurality of groups along the circumference of the slot plate 10, and in each group of the filter rod slot groups 200, there is one filter rod slot 20 on which the cutting groove 30 is distributed that completely matches. Wherein, in each group of the filter rod slot groups 200, there is one filter rod slot 20 on which the cutting groove 30 is distributed that completely matches means that the axial distribution positions of the cutting grooves 30 on these filter rod slots 20 completely match. For example, Figure 4 In the illustrated embodiment, the cutter grooves 30 distributed on the filter rod slot 20 with station number 1 are completely matched, the cutter grooves 30 distributed on the filter rod slot 20 with station number 2 are completely matched, the cutter grooves 30 distributed on the filter rod slot 20 with station number 3 are completely matched, and the cutter grooves 30 distributed on the filter rod slot 20 with station number 4 are completely matched. That is to say, every 4 stations are a cycle, corresponding to four groups of rod materials in sequence.

[0043] Specifically, in one embodiment, the 32 filter rod slots 20 on the slot plate 10 are divided into 4 workstations, and each 4 workstations form a cycle, corresponding to four groups of rod materials in sequence. The distribution of the cutting grooves 30 is designed by using different workstations and work areas, so as to avoid the situation where the spacing between the cutting grooves 30 is too small or overlaps with each other, thereby better ensuring the cutting effect of the filter rod. More preferably, in order to ensure the cutting effect, the axial distance between two adjacent cutting grooves 30 is greater than 2 mm.

[0044] More specifically, in order to further improve production efficiency and increase the number of filter rod slots 20 that can be used in each production, the filter rod slots 20 of each workstation number can be adapted to the production of multiple rod material numbers. Figure 5 As shown, Figure 5The numbers on the left side of the filter rod slots represent the rod material numbers in Table 1 above, so as to achieve the optimal distribution of the filter rod slots 20 and the cutter slots 30. In the axial direction, the filter rod slots 20 can be divided into multiple zones, for example Figure 5 Area A, area B and area C are shown to better meet the needs of slitting filter rods of different specifications.

[0045] Preferably, in one embodiment, a threaded hole 112 is provided on the end face of the fixing member 11, and the mounting portion 122 is connected to the threaded hole 112 by bolts. A mounting groove 1221 is provided on the mounting portion 122 corresponding to the threaded hole 112, and the mounting groove 1221 extends along the circumference of the slot plate 10. That is to say, in this embodiment, the movable member 12 is specifically detachably connected to the fixing member 11 by bolts, and the mounting groove 1221 provided on the movable member 12 is an arc groove, and this arc groove extends along the circumference, so that after the bolts are loosened, the position of the movable member 12 can be rotated along the circumference, and after the rotation is completed, there is still an area on the mounting groove 1221 corresponding to the threaded hole 112, so that the position of the movable member 12 can continue to be fixed by tightening the bolts, thereby completing the adjustment of the mounting position of the movable member 12 and realizing the adjustment of the slot width of the filter rod slot 20. Of course, in other embodiments, any other desired structure may be used to achieve the connection and fixation of multiple installation positions between the movable member 12 and the fixed member 11. In this embodiment, the structure of the circumferentially extending installation groove 1221 can facilitate the operator to control and adjust the movable member 12.

[0046] Please refer to Figure 1 and 6 Meanwhile, in one embodiment, a slitting hub wheel 1000 is also provided, which comprises a hub wheel shaft 300, a hub wheel body 400 and a slot plate structure 100 of the slitting hub wheel, wherein the hub wheel body 400 is arranged on the hub wheel shaft 300, and the fixing member 11 is arranged on the periphery of the hub wheel body 400. The slitting drum wheel 1000 can be specifically installed on the back plate 2000 of the filter rod slitting device.

[0047] Preferably, in one embodiment, the slitting hub wheel 1000 is intermittently operated. The intermittent operation of the slitting hub wheel 1000 can be realized by using an intermittent driving mechanism or a corresponding connection structure, for example, the hub wheel shaft 300 can be driven by an intermittently operated motor; or the dial 301 can be connected to the motor, and the pin of the dial 301 is inserted into the groove wheel 302, the groove wheel 302 is connected to the hub wheel shaft 300, the motor provides power to the dial 301 to make it rotate at a uniform speed, and the dial 301 makes the groove wheel 302 do intermittent motion.

[0054] Preferably, in one embodiment, a sealing ring 313 is provided between the end surface of the hub wheel core 401 and the hub wheel core shaft 311. Specifically, in one embodiment, the hub wheel core shaft 311 and the sealing ring 313 are fixed to the back plate 2000 by bolts.

[0055] Preferably, in one embodiment, a slitting cover plate 500 is further provided on the outer side of the slot plate 10. The slitting cover plate 500 may be provided with a corresponding avoidance structure corresponding to the position of the cutter slot 30 to avoid the cutter. The slitting cover plate 500 is mainly used to press the filter rod to a slight deformation to prevent the filter rod from rotating in the filter rod slot 20, resulting in poor slitting effect.

[0056] The slitting cover plate 500 is disposed at the slitting station of the slitting hub wheel 1000 and is spaced apart from the slitting hub wheel 1000. Specifically, when the filter rod slot 20 rotates to the slitting station, the spacing distance between the inner surface of the slitting cover plate 500 and the bottom of the filter rod slot 20 is smaller than the diameter of the filter rod, so that the inner surface of the slitting cover plate 500 can squeeze the filter rod accordingly, thereby pressing the filter rod tightly in the filter rod slot 20, thereby preventing the filter rod from rotating in the filter rod slot 20 when the cutter cuts the filter rod.

[0057] Specifically, the slitting cover plate 500 can be installed on the back plate 2000. It is only necessary that a part of the structure on the slitting cover plate 500 is located at the slitting position of the slitting hub wheel 1000 and is spaced from the slitting hub wheel 1000, so that the filter rod located at the slitting position of the slitting hub wheel 1000 can be pressed by the corresponding structure on the slitting cover plate 500.

[0058] It should be noted that, considering that the diameters of the filter rods of various specifications to be cut are different, and the positions of the cutting grooves 30 distributed on the filter rod slots 20 at each station are different, the cutting cover plate 500 is a standard part, and different specifications can be designed according to the specifications of the filter rods to be generated. For example, as in the above embodiment, the filter rod slots 20 of four different stations have different positions of the cutting grooves 30, so four sets of cutting cover plates 500 of different specifications can be made accordingly; and the 5.4mm and 6.3mm filter rods share the same thickness cover plate, and the 7.1mm and 7.4mm share another thickness cover plate, so the cutting cover plates 500 have 4*2 sets of different specifications, and one cutting hub wheel 1000 can correspond to 8 sets of cutting cover plates 500 of different specifications for adaptation and use.

[0059] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
