Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging, and in particular to a long-side folder. Background Art

[0002] At the present stage in the technical field of tobacco production, after cigarette sticks are manufactured, they are packaged into boxes and then into strips. A cigarette packaging machine is often used to seal the produced cigarette products. The cigarette packaging machine is connected to the cigarette making machine. After being screened, qualified cigarette sticks will enter the cigarette box. An accurate number of cigarettes will be loaded into a cigarette box with a pre-printed barcode label formed by a cigarette inner box packaging machine. After being put into the box, inspection and plastic sealing work will be carried out; after the plastic sealing of the cigarette box is completed, the cigarette box will be loaded into the outer strip packaging by a cigarette outer strip packaging machine, and then plastic sealed again to form a complete cigarette strip; after the plastic sealing of the cigarette strip is completed, it will be conveyed to a packing machine by a conveyor belt, and the packing machine will pack and bundle the cigarette strips according to the target quantity; the cigarette box formed after packing is used as the basic unit for factory storage or logistics.

[0003] In the selection of cigarette inner box packaging machines and cigarette outer strip packaging machines, taking the FOCKE FXS soft box high-speed packaging machine as an example, its holding quantity is still very high. However, the long-side folding device used on the trademark paper of this machine still uses a bakelite folder processed integrally. Since the packaging speed of the FOCKE FXS soft box high-speed packaging machine is as high as 700 packs per minute, the claw tip part of the folder is extremely easy to wear. After wear, the long side of the trademark paper will not be folded in place, resulting in various packaging quality problems. Improving the folder has always been a problem and a research hotspot in the tobacco field. Since the existing folders are generally processed integrally, the replacement cost is extremely high; moreover, along with the narrow installation space and other situations, the replacement and maintenance operations are extremely difficult.

[0049] Such asFigures 1 to 16 As shown in the figure, the present invention discloses a long-side folder, which includes a flange shaft 1, an inner claw disc module 2, a middle claw disc module 3, and an outer claw disc module 4 that are coaxially arranged and detachably connected in sequence along the axial direction. The long-side folder is installed at the long-side folding position of the trademark paper. The flange shaft 1 is coaxially connected to the machine power output shaft, which is used to provide power for the self-rotation of the flange shaft 1, and can make relative motion with the packaging turret of the FOCKE FXS soft box high-speed packaging machine. When the trademark paper reaches the folding position, the long-side folder rotates relatively. By subdividing into a modular assembly structure, the processing cost and difficulty are greatly reduced, and the cost of each maintenance and replacement is also correspondingly greatly reduced; and after modularization, the operation of the entire installation and maintenance becomes easier and simpler, which can cope with the space limitation of the production workshop, and has a good application prospect in the tobacco industry.

[0050] Among them, the inner claw disc module 2 includes an inner claw disc 21 and inner claws 22, the middle claw disc module 3 includes a middle claw disc 31 and middle claws 32, the outer claw disc module 4 includes an outer claw disc 41 and outer claws 42. The inner claws 22, middle claws 32, and outer claws 42 are arranged at intervals in a straight line direction, and the straight line direction is parallel to the axial direction of the long-side folder; the inner claws 22, middle claws 32, and outer claws 42 are all provided with folding teeth 5, and the tip direction of the folding teeth 5 is perpendicular to the operation surface on the outside of the long-side folder. The operation surface is parallel to the axial direction of the long-side folder. The inner claws 22, middle claws 32, and outer claws 42 located on the same side of the operation surface together form a folding claw. Whenever the operation surface makes a relative motion with the trademark paper once, a whole-side folding of the long side of the trademark paper can be completed.

[0051] The operation surface includes a first operation surface 207 located on the inner claw disc 21, a second operation surface 305 located on the middle claw disc 31, and a third operation surface 405 located on the outer claw disc 41; the inner claws 22 are detachably arranged on the first operation surface 207, the middle claws 32 are detachably arranged on the second operation surface 305, and the outer claws 42 are detachably arranged on the third operation surface 405. That is, the inner claws 22 are detachably connected to the inner claw disc 21, the middle claws 32 are detachably connected to the middle claw disc 31, and the outer claws 42 are detachably connected to the outer claw disc 41. The most easily worn claw parts in each module can be disassembled from the corresponding claw discs again. After any one of the inner claws 22, middle claws 32, and outer claws 42 is worn, only the corresponding single claw part needs to be replaced, further reducing the replacement cost and improving the maintenance efficiency.

[0052] Specifically, a plurality of operating surfaces are provided on the outer side of the long-edge folder. The plurality of operating surfaces are arranged in a circumferential array along the long-edge folder. The inner claws 22, the middle claws 32, and the outer claws 42 are all arranged in one-to-one correspondence with the operating surfaces. In this embodiment, 4 operating surfaces are provided on the outer side of the long-edge folder. Each time the long-edge folder rotates 90°, one operating surface faces the label paper for the folding process. Each time the long-edge folder rotates one week, 4 folds of the long edge of the label paper can be completed, which can effectively improve the packaging efficiency and avoid the accelerated wear and the rate of replacement and maintenance that may be caused by the frequent operation of a single set of folding claws.

[0053] Further, a first claw groove 201 is provided on the inner claw disc 21. A part of the inner claw 22 is embedded in the first claw groove 201. The inner claw disc 21 is provided with a first installation through hole 202. The inner claw disc module 2 further includes a first installation claw connecting piece 11. The first installation claw connecting piece 11 can pass through the first installation through hole 202 to connect the inner claw disc 21 and the inner claw 22.

[0054] In this embodiment, the inner claw disc 21 includes an inner left claw disc 211 and an inner right claw disc 212, which can improve the simplicity of replacement and reduce the production cost. Among them, two inner claws 22 are respectively arranged on the inner left claw disc 211 and the inner right claw disc 212, and the corresponding number of first claw grooves 201 are dug. The first installation claw connecting piece 11 can be selected as a bolt. Correspondingly, a threaded hole is also provided on the inner claw 22. The first installation through hole 202 communicates with the first claw groove 201, and the bolt can be screwed with the threaded hole through the first installation through hole 202 to fix the inner claw 22 to the inner claw disc 21.

[0055] Similarly, a second claw groove 301 is provided on the middle claw disc 31. A part of the middle claw 32 is embedded in the second claw groove 301. The middle claw disc 31 is provided with a second installation through hole 302. The middle claw disc module 3 further includes a second installation claw connecting piece 12. The second installation claw connecting piece 12 can pass through the second installation through hole 302 to connect the middle claw disc 31 and the middle claw 32.

[0056] In this embodiment, four middle claws 32 are arranged on one middle claw disc 31, and four second claw grooves 301 are dug. The second installation claw connecting piece 12 can also be selected as a bolt. Correspondingly, a threaded hole is provided on the middle claw 32. The second installation through hole 302 communicates with the second claw groove 301, and the bolt can be screwed with the threaded hole through the second installation through hole 302 to fix the middle claw 32 to the middle claw disc 31.

[0057] Similarly, a third claw groove 401 is provided on the outer claw disc 41. A part of the outer claw 42 is embedded outside the third claw groove 401. The outer claw disc 41 is provided with a third installation through hole 402. The outer claw disc module 4 further includes a third installation claw connecting piece 13. The third installation claw connecting piece 13 can pass through the third installation through hole 402 to connect the outer claw disc 41 and the outer claw 42.

[0058] In this embodiment, four outer claws 42 are arranged on an outer claw disc 41, and four third claw grooves 401 are dug. The third mounting claw connecting member 13 can also be selected as a bolt. Correspondingly, threaded holes are formed in the outer claws 42. The third mounting through holes 402 communicate with the third claw grooves 401, and the bolt can be screwed with the threaded holes through the third mounting through holes 402 to fix the outer claws 42 to the outer claw disc 41.

[0059] Specifically, as Figures 2 to 7 shown, in one of the flange shaft 1 and the inner claw disc 21, a first threaded hole 101 is formed, and in the other, a first through hole 203 is formed. The long-edge folder further includes a first connecting bolt 6, and the first connecting bolt 6 can pass through the first through hole 203 and be threadedly connected with the first threaded hole 101. In this embodiment, the first through hole 203 is formed in the inner claw disc 21 and is a countersunk hole. The first through holes 203 are respectively formed in the inner left claw disc 211 and the inner right claw disc 212. At the same time, two first threaded holes 101 are symmetrically arranged on the flange shaft 1, and there are two first connecting bolts 6 respectively located on the inner left claw disc 211 and the inner right claw disc 212 to stably connect the flange shaft 1 and the inner claw disc module 2.

[0060] To further ensure the stability of the long-edge folder and the coaxiality between modules, a first pin hole 102 is formed in the flange shaft 1, and a second pin hole 204 is formed in the inner claw disc 21. The long-edge folder further includes a first pin 7, and the first pin 7 is inserted through the first pin hole 102 and the second pin hole 204. Exemplarily, the first pin 7 includes two specifications, and the two specifications of the first pins 7 are symmetrically arranged in a staggered manner on the inner left claw disc 211 and the inner right claw disc 212 as an anti-mistake design, which can stably disassemble and assemble the inner left claw disc 211 and the inner right claw disc 212 separately to avoid wrong installation.

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

[0062] Optionally, in both the inner claw plate 21 and the outer claw plate 41, one of them is provided with a second threaded hole 205, and the other is provided with a second through hole 403. The middle claw plate 31 is provided with a third through hole 303. The long-edge folder further includes a second connecting bolt 8. The second connecting bolt 8 can sequentially pass through the second through hole 403 and the third through hole 303 and be threadedly connected to the second threaded hole 205. In this embodiment, the second threaded holes 205 are respectively provided on the inner left claw plate 211 and the inner right claw plate 212. Two second through holes 403 are symmetrically arranged on the outer claw plate 41. There are two second connecting bolts 8 respectively used to fix the inner left claw plate 211, the middle claw plate 31 and the outer claw plate 41 to the inner right claw plate 212, the middle claw plate 31 and the outer claw plate 41, so as to stably connect the inner claw plate module 2, the middle claw plate module 3 and the outer claw plate module 4.

[0063] To further ensure the stability of the long-edge folder and the coaxiality between modules, a third pin hole 206 is provided on the inner claw plate 21, a fourth pin hole 304 is provided on the middle claw plate 31, and a fifth pin hole 404 is provided on the outer claw plate 41. The long-edge folder further includes a second pin 9. The second pin 9 is inserted through the third pin hole 206, the fourth pin hole 304 and the fifth pin hole 404. Exemplarily, the second pin 9 includes two specifications. The second pins 9 of these two specifications are symmetrically arranged in a staggered manner on the inner left claw plate 211 and the inner right claw plate 212 as an anti-mistake 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 standardize the installation angles of the middle claw plate 31 and the outer claw plate 41, maintain the linearity 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 claw plate 31 and the outer claw plate 41 are fixedly connected to the inner left claw plate 211 through a second pin 9 and a second connecting bolt 8; the middle claw plate 31 and the outer claw plate 41 are fixedly connected to the inner right claw plate 212 through a first pin 7 and a first connecting bolt 6. The two second pins 9 have different specifications.

[0065] Specifically, as Figure 4 and Figure 5As shown in the figure, a power installation through-hole 103 is provided at the center of the flange shaft 1. The power installation through-hole 103 is used to insert the power output shaft of the machine. The flange shaft 1 is provided with a structural through-slot 104. The depth direction of the structural through-slot 104 is parallel to the axial direction of the flange shaft 1. The two side walls of the structural through-slot 104 communicate the power installation through-hole 103 with the outer periphery of the flange shaft 1 and are divided into two parts by the structural through-slot 104. The long-edge folder further includes a fastening connecting member 10. The flange shaft 1 is provided with a fastening connection through-hole 105 perpendicular to the two side walls of the structural through-slot 104. The fastening connecting member 10 can pass through the fastening connection through-hole 105 to deform the structural through-slot 104 for locking the power output shaft of the machine. In this embodiment, the fastening connection through-hole 105 is specifically set as a countersunk threaded hole, and the fastening connecting member 10 is specifically set as a bolt. When the bolt enters the countersunk threaded hole and is screwed threadedly, the structural through-slot 104 can be deformed and narrowed, and the outer walls of the power installation through-hole 103 divided into two parts approach each other, tightly wrap and lock around the outer periphery of the power output shaft of the machine, which can improve the installation stability of the long-edge folder.

[0066] It can be understood that the above-mentioned threaded holes, pin holes, through-holes, etc. for assembling various connecting members can be selectively in the form of countersunk slots. In the flange shaft 1, the inner claw disc module 2, the middle claw disc module 3, and the outer claw disc module 4, setting the countersunk slot can not only avoid the danger of the connecting member protruding from the disc body and causing interference, but also facilitate the installation and removal of the connecting member.

[0067] As Figures 14 to 16 shown in the figure, three folding teeth 5 are arranged at intervals along the straight line direction on the inner claw 22, two folding teeth 5 are arranged at intervals along the straight line direction on the middle claw 32, and one folding tooth 5 is arranged on the outer claw 42. The arrangement of the number of folding teeth 5 is mainly designed according to the folding effect, and the interference situation with other mechanisms during folding also needs to be considered.

[0068] Exemplarily, in addition to being used for folding the long edge of the trademark paper, the long-edge folder can also be applied to similar packaging folding process equipment. In order to better fit and meet the length of the object to be folded, or to adapt to the long edges of trademark papers of different lengths, the long-edge folder can include a plurality of middle claw disc modules 3 connected axially. A plurality of middle claws 32 are arranged at intervals along the straight line direction.
