Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, and in particular to a long-side folding device. Background Technology

[0002] Currently, in the tobacco production technology field, after cigarette sticks are manufactured, they are packaged into cartons. Cigarette packaging machines are frequently used to seal the produced cigarette products. The cigarette packaging machine is connected to the cigarette rolling machine. After screening, qualified cigarette sticks enter the packaging box. A precise number of cigarettes are loaded into pre-printed barcode labels into cigarette boxes via an inner packaging machine. After being placed in the box, they undergo inspection and sealing. The sealed cigarette boxes are then loaded into outer packaging by an outer packaging machine, and then sealed again to form a complete cigarette carton. After the cigarette carton is sealed, it is conveyed to a case packing machine via a conveyor belt. The case packing machine packs the cigarette cartons into boxes according to the target quantity. The resulting cigarette boxes serve as the basic unit for factory storage or logistics.

[0003] In the selection of cigarette inner box packaging machines and cigarette outer carton packaging machines, taking the FOCKE FXS soft-pack high-speed packaging machine as an example, its usage rate remains high. However, the long-side folding device on the label paper used in this machine still uses a one-piece phenolic resin folder. Because the FOCKE FXS soft-pack high-speed packaging machine has a packaging speed of up to 700 packs per minute, the claw tips of the folder are extremely prone to wear. After wear, the long edge of the label paper will not be folded properly, resulting in various packaging quality problems. Improving the folder has always been a problem and a hot research topic in the tobacco industry. Because existing folders are generally made in one piece, the replacement cost is extremely high; furthermore, the limited installation space makes replacement and maintenance extremely difficult.

[0004] Therefore, there is an urgent need to design a folding device that is inexpensive to manufacture and replace, and easy to repair and maintain, which can be used for folding the long side of label paper and meet the on-site installation conditions of packaging equipment.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] like Figures 1 to 16 As shown, this utility model discloses a long-side folding device, including a flange shaft 1, an inner claw plate module 2, a middle claw plate module 3, and an outer claw plate module 4, which are coaxially arranged and detachably connected in sequence along the axial direction. The long-side folding device is installed on the long-side folding position of the label paper. The flange shaft 1 is coaxially connected to the machine's power output shaft to provide power for the rotation of the flange shaft 1. This allows it to move relative to the packaging turret of the FOCKE FXS soft-pack high-speed packaging machine. When the label paper reaches the folding position, the long-side folding device rotates relative to it. By dividing the assembly structure into modular components, the processing cost and difficulty are significantly reduced, resulting in a substantial decrease in the cost of each maintenance and replacement. Furthermore, modularization makes the entire installation and maintenance operation easier and simpler, addressing the space constraints of production workshops, and showing promising application prospects in the tobacco industry.

[0050] The inner claw plate module 2 includes an inner claw plate 21 and an inner claw 22; the middle claw plate module 3 includes a middle claw plate 31 and a middle claw 32; and the outer claw plate module 4 includes an outer claw plate 41 and an outer claw 42. The inner claw 22, the middle claw 32, and the outer claw 42 are spaced apart along a straight line, which is parallel to the axial direction of the long side folder. The inner claw 22, the middle claw 32, and the outer claw 42 are all provided with folding teeth 5. The tooth tips of the folding teeth 5 are perpendicular to the operating surface on the outside of the long side folder. The operating surface is parallel to the axial direction of the long side folder. The inner claw 22, the middle claw 32, and the outer claw 42 located on the same side of the operating surface together form a folding claw. Each time the operating surface moves relative to the trademark paper once, the entire long side of the trademark paper can be folded once.

[0051] The operating surfaces include a first operating surface 207 located on the inner jaw disk 21, a second operating surface 305 located on the middle jaw disk 31, and a third operating surface 405 located on the outer jaw disk 41. The inner jaw 22 is detachably mounted on the first operating surface 207, the middle jaw 32 is detachably mounted on the second operating surface 305, and the outer jaw 42 is detachably mounted on the third operating surface 405. That is, the inner jaw 22 is detachably connected to the inner jaw disk 21, the middle jaw 32 is detachably connected to the middle jaw disk 31, and the outer jaw 42 is detachably connected to the outer jaw disk 41. The most easily worn jaw in each module can be separated from the corresponding jaw disk again. When any of the inner jaw 22, middle jaw 32, and outer jaw 42 becomes worn, only the corresponding individual jaw needs to be replaced, further reducing replacement costs and improving maintenance efficiency.

[0052] Specifically, the outer side of the long-side folding device is provided with multiple operating surfaces, which are arranged circumferentially along the long-side folding device. The inner claw 22, middle claw 32, and outer claw 42 are all arranged in a one-to-one correspondence with the operating surfaces. In this embodiment, four operating surfaces are provided on the outer side of the long-side folding device. Every time the long-side folding device rotates 90°, one operating surface is opposite to the label paper to perform a folding process. Every time the long-side folding device rotates once, it can complete four folds on the long side of the label paper, which can effectively improve packaging efficiency and avoid the frequent operation of a single set of folding claws, which may lead to accelerated wear and tear and replacement and maintenance rates.

[0053] Furthermore, a first claw groove 201 is provided in the inner claw disk 21, and a portion of the inner claw 22 is embedded in the first claw groove 201. The inner claw disk 21 has a first mounting through hole 202. The inner claw disk module 2 also includes a first mounting claw connector 11, which can pass through the first mounting through hole 202 to connect the inner claw disk 21 and the inner claw 22.

[0054] In this embodiment, the inner claw disk 21 includes an inner left claw disk 211 and an inner right claw disk 212, which can improve the ease of replacement and reduce production costs. The inner left claw disk 211 and the inner right claw disk 212 are each equipped with two inner claws 22, and a corresponding number of first claw grooves 201 are formed therein. The first mounting claw connector 11 can be a bolt. Correspondingly, threaded holes are also formed on the inner claws 22. The first mounting through hole 202 connects to the first claw groove 201, and the bolt can be screwed into the threaded hole through the first mounting through hole 202 to fix the inner claws 22 to the inner claw disk 21.

[0055] Similarly, a second claw groove 301 is provided in the middle claw disk 31, and part of the middle claw 32 is embedded in the second claw groove 301. The middle claw disk 31 is provided with a second mounting through hole 302. The middle claw disk module 3 also includes a second mounting claw connector 12, which can pass through the second mounting through hole 302 so that the middle claw disk 31 and the middle claw 32 are connected.

[0056] In this embodiment, a middle claw disk 31 is provided with four middle claws 32 and has four second claw grooves 301. The second mounting claw connector 12 can also be a bolt. Correspondingly, a threaded hole is provided on the middle claw 32. The second mounting through hole 302 communicates with the second claw groove 301. The bolt can be screwed into the threaded hole through the second mounting through hole 302 to fix the middle claw 32 to the middle claw disk 31.

[0057] Similarly, a third claw groove 401 is provided in the outer claw disk 41, and part of the outer claw 42 is embedded in the third claw groove 401. The outer claw disk 41 is provided with a third mounting through hole 402. The outer claw disk module 4 also includes a third mounting claw connector 13, which can pass through the third mounting through hole 402 so that the outer claw disk 41 and the outer claw 42 can be connected.

[0058] In this embodiment, an outer claw disk 41 is provided with four outer claws 42 and has four third claw grooves 401. The third mounting claw connector 13 can also be a bolt. Correspondingly, a threaded hole is provided on the outer claw 42, and the third mounting through hole 402 connects to the third claw groove 401. The bolt can be screwed into the threaded hole through the third mounting through hole 402 to fix the outer claw 42 to the outer claw disk 41.

[0059] Specifically, such as Figures 2 to 7 As shown, in both the flange shaft 1 and the inner jaw disk 21, one has a first threaded hole 101 and the other has a first through hole 203. The long-side folding device also includes a first connecting bolt 6, which can pass through the first through hole 203 and be threadedly connected to the first threaded hole 101. In this embodiment, the first through hole 203 is countersunk in the inner jaw disk 21. The first through holes 203 are respectively provided in the inner left jaw disk 211 and the inner right jaw disk 212. At the same time, two first threaded holes 101 are symmetrically arranged on the flange shaft 1. There are two first connecting bolts 6 located in the inner left jaw disk 211 and the inner right jaw disk 212 respectively, so as to stably connect the flange shaft 1 and the inner jaw disk module 2.

[0060] To further ensure the stability of the long-side folding device and the coaxiality between the modules, a first pin hole 102 is provided on the flange shaft 1, and a second pin hole 204 is provided on the inner claw disk 21. The long-side folding device also includes a first pin 7, which passes through the first pin hole 102 and the second pin hole 204. For example, the first pin 7 includes two specifications, which are centrally symmetrically staggered on the inner left claw disk 211 and the inner right claw disk 212, respectively, as a foolproof design to reliably allow for the individual assembly and disassembly of the inner left claw disk 211 and the inner right claw disk 212, avoiding incorrect or reversed assembly.

[0061] The flange shaft 1 is fixedly connected to the inner left claw disk 211 by two first pins 7 of different specifications and a first connecting bolt 6; the flange shaft 1 is fixedly connected to the inner right claw disk 212 by two first pins 7 of different specifications and a first connecting bolt 6.

[0062] Optionally, in both the inner jaw disk 21 and the outer jaw disk 41, one has a second threaded hole 205 and the other has a second through hole 403. The middle jaw disk 31 has a third through hole 303. The long-side folding device also includes a second connecting bolt 8, which can pass through the second through hole 403 and the third through hole 303 in sequence and be threadedly connected to the second threaded hole 205. In this embodiment, the inner left jaw disk 211 and the inner right jaw disk 212 are respectively provided with second threaded holes 205, and the outer jaw disk 41 is symmetrically provided with two second through holes 403. There are two second connecting bolts 8, which are used to fix the inner left jaw disk 211, the middle jaw disk 31 and the outer jaw disk 41 to the inner right jaw disk 212, the middle jaw disk 31 and the outer jaw disk 41, so as to stably connect the inner jaw disk module 2, the middle jaw disk module 3 and the outer jaw disk module 4.

[0063] To further ensure the stability of the long-side folder and the coaxiality between modules, a third pin hole 206 is provided in the inner claw plate 21, a fourth pin hole 304 is provided in the middle claw plate 31, and a fifth pin hole 404 is provided in the outer claw plate 41. The long-side folder also includes a second pin 9, which passes through the third pin hole 206, the fourth pin hole 304, and the fifth pin hole 404. For example, the second pin 9 includes two specifications, which are centrally symmetrically staggered on the inner left claw plate 211 and the inner right claw plate 212, respectively, as a foolproof design. In addition to ensuring the correct assembly of the inner left claw plate 211 and the inner right claw plate 212, it can also regulate the installation angle of the middle claw plate 31 and the outer claw plate 41, maintain the straightness of the inner claw 22, the middle claw 32, and the outer claw 42, and maintain the effect of the folding process.

[0064] The middle jaw plate 31 and the outer jaw plate 41 are fixedly connected to the inner left jaw plate 211 by a second pin 9 and a second connecting bolt 8; the middle jaw plate 31 and the outer jaw plate 41 are fixedly connected to the inner right jaw plate 212 by a first pin 7 and a first connecting bolt 6, and the two second pins 9 are of different specifications.

[0065] Specifically, such as Figure 4 and Figure 5As shown, the flange shaft 1 has a power mounting through hole 103 at its center, which is used to insert the machine's power output shaft; the flange shaft 1 has a structural through groove 104, the depth direction of which is parallel to the axial direction of the flange shaft 1, and the two side walls of the structural through groove 104 connect the power mounting through hole 103 and the outer periphery of the flange shaft 1, and are divided into two halves by the structural through groove 104; the long side folder also includes a fastening connector 10, the flange shaft 1 has a fastening connection through hole 105 perpendicular to the two side walls of the structural through groove 104, the fastening connector 10 can be inserted into the fastening connection through hole 105 to deform the structural through groove 104, and is used to lock the machine's power output shaft. In this embodiment, the fastening connection through hole 105 is specifically configured as a countersunk threaded hole, and the fastening connection 10 is specifically configured as a bolt. The bolt enters the countersunk threaded hole and is screwed in, which can deform and narrow the structural through groove 104. The outer walls of the two-part power mounting through hole 103 approach each other, tightly cover and lock the outer periphery of the machine power output shaft, which can improve the installation stability of the long side folding device.

[0066] It is understandable that the threaded holes, pin holes, and through holes used for assembling various connecting parts can all be selectively designed with countersunk grooves. In the flange shaft 1, inner jaw plate module 2, middle jaw plate module 3, and outer jaw plate module 4, countersunk grooves can not only avoid the danger of interference caused by the connecting parts protruding from the plate body, but also facilitate the installation and removal of the connecting parts.

[0067] like Figures 14 to 16 As shown, the inner jaw 22 is provided with three folding teeth 5 at intervals along the straight direction, the middle jaw 32 is provided with two folding teeth 5 at intervals along the straight direction, and the outer jaw 42 is provided with one folding tooth 5. The arrangement of the number of folding teeth 5 is mainly designed according to the folding effect, and the interference with other mechanisms during folding must also be considered.

[0068] For example, in addition to folding long edges on label paper, the long edge folder can also be applied to similar packaging folding equipment. In order to better fit the length of the folded object, or to adapt to the long edges of label paper of different lengths, the long edge folder may include multiple middle claw disk modules 3 connected along the axial direction. The multiple middle claws 32 are spaced apart along the straight direction. The specific number of middle claw disk modules 3 is set by the staff according to the application scenario, which will not be elaborated here.

[0069] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
