Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing equipment technology, and in particular to an apparatus for producing inner packaging for hard cigarettes. Background Technology

[0002] Generally speaking, tobacco products, especially cigarettes, need to be packaged before being sold. Traditional cigarette packaging mainly consists of an inner pack and an outer box. The inner pack primarily includes the cigarette pack, aluminum foil, and an inner frame, while the outer box mainly includes the label and a transparent liner. The inner pack typically uses aluminum foil to preserve the aroma of the cigarettes and prevent them from getting damp, while the inner frame maintains the shape of the pack.

[0003] In recent years, with the increasing saturation of the traditional cigarette market and consumers' growing demand for personalized cigarettes, various uniquely shaped cigarette packages have been introduced to the market, with the "box-in-box" being one such example. A box-in-box consists of a rigid inner pack and an outer box. The main difference between the rigid inner pack and traditional cigarette packs is the absence of aluminum foil and inner frame paper. Instead, a rigid cardboard directly wraps the cigarette pack. This cardboard not only protects the aroma of the cigarettes but also maintains the box's shape, while allowing the inner pack to be removed independently for convenient carrying and use.

[0004] This rigid inner packaging process represents a significant departure from traditional aluminum foil cigarette inner packaging, involving a highly complex packaging process. It requires not only the orderly attachment of the unwrapped cigarette pack to the rigid cardboard, but also maintaining the specific arrangement of the cigarette pack during folding and movement. Finally, various folding mechanisms are used to enclose the cigarette pack within the rigid cardboard, forming the rigid cigarette inner pack.

[0005] Regarding the inner packaging of the aforementioned hard cigarettes, a domestic cigarette manufacturer has upgraded its YB43 packaging machine. However, the YB43's packaging technology is outdated, with limited room for improvement, resulting in a machine operating speed of only 70 packs per minute and severely insufficient production efficiency. Furthermore, the lack of necessary packaging actions and protective mechanisms leads to a very high rate of empty cigarette ends, resulting in inconsistent packaging quality and seriously impacting the cigarette factory's quality requirements for cigarette packaging. Summary of the Invention

[0052] like Figures 1-10 As shown, the present invention provides an apparatus for producing inner packaging of hard cigarettes (hereinafter referred to as the inner packaging production apparatus), including a base (not shown in the figure), a packaging wheel 20, the packaging wheel 20 being disposed in the base; the packaging wheel 20 includes a packaging wheel drive source, a wheel disk 201, and a plurality of mold boxes 202 disposed on the wheel disk 201, the wheel disk 201 being horizontally disposed above the base; it also includes a plurality of workstations, namely a paper-patting workstation a, a flaring workstation b, a cigarette-feeding workstation c, a first folding workstation d, a second folding workstation e, a third folding workstation f, and an output workstation g; corresponding workstation execution mechanisms are disposed on the outside of the plurality of workstations, the hard cardboard 1 is placed in the mold box 202, and under the drive of the packaging wheel drive source, passes sequentially through the workstation execution mechanisms at the above-mentioned plurality of workstations to complete the production of the inner packaging of hard cigarettes;

[0053] A flaring mechanism 22 is provided on the outside of the flaring station b for flaring the inner package; a reciprocating mold box mechanism 23 is provided on the outside of the cigarette inlet station c for placing cigarettes into the inner package; a movable folding device 28 is also provided on the outside of the third folding station f for folding the inner package; an inner package protective plate 27 is also provided between the cigarette inlet station c and the second folding station e, and the inner package protective plate 27 applies pressure to the cigarettes in the inner package.

[0054] The number of workstations is a multiple of four and greater than six.

[0055] The present invention relates to an apparatus for producing hard cigarette inner packaging. A plurality of mold boxes 202 are provided on a rotary disc 201, and a plurality of workstations are set up. Hard cardboard 1 is placed in the mold box 202. A packaging wheel drive source drives the rotary disc 201 to rotate, causing the mold boxes 202 to rotate around the rotary disc 201. The hard cardboard 1 in each mold box 202 follows the rotary disc 201 sequentially through the aforementioned workstations. The corresponding mechanisms at each workstation operate to manipulate the hard cardboard 1, completing the folding and packaging of the cigarette inner packaging. Compared to existing technologies that modify old equipment, this method offers higher production efficiency and better cigarette packaging quality.

[0056] Preferred, such as Figures 3-7 As shown, the inner package includes the right corner 11, the left corner 12, the front short side 13, the small side 14, the large side 15, the left long side 16, and the right long side 17. The inner package is a rectangular box, and the cigarette set 6 is placed in the inner package.

[0057] Furthermore, such as Figure 1 , Figure 2 As shown, in this embodiment, the mold box 202 is located at the edge of the wheel 201. The mold box 202 is a rectangular box, and the size of the mold box 202 is the same as that of the inner packaging. The top of the mold box 202 and the end of the mold box 202 away from the wheel 201 are open, which makes it easy to place the cardboard 1 into the mold box 202 and perform subsequent inner packaging folding.

[0058] Preferred, such as Figure 1 , Figure 2 , Figure 8 As shown, a paper-tapping mechanism 21 is provided on the outside of the paper-tapping station a. The paper-tapping mechanism 21 includes a paper-tapping drive source, a paper-tapping board 212, and a rotating arm 211. One end of the rotating arm 211 is hinged to the base. The paper-tapping board 212 is located at the end of the rotating arm 211 away from the base. The paper-tapping drive source is connected to the rotating arm 211 in a transmission connection.

[0059] In this embodiment, a rotating arm support frame is also provided on the base, and the rotating arm 211 is hinged to the rotating arm support frame. When the mold box 202 rotates to the paper-feeding station a, the wheel 201 is stationary. After the external paper conveying equipment transports the cardboard 1 to directly above the mold box 202, the paper-feeding drive source works to drive the rotating arm 211 to swing (e.g., Figure 8 As indicated by the arrow in the diagram (in terms of rotation direction), the rotating arm 211 rotates, thereby driving the tack plate 212 to tack the cardboard 1 into the mold box 202, thus forming the primary folded cigarette pack 2 (as shown in the diagram). Figure 4 (As shown), then the paper-tapping drive source drives the rotating arm 211 to swing in the opposite direction, away from the mold box 202.

[0060] Preferred, such as Figure 1 , Figure 2 , Figure 8 As shown, a flaring mechanism 22 is provided on the outside of the flaring station b. The flaring mechanism 22 includes a flaring drive source, a flaring four-bar linkage assembly 221, and a flaring shaping plate 222. The bottom end of the flaring four-bar linkage assembly 221 is connected to the base, and the flaring four-bar linkage assembly 221 is connected to the flaring shaping plate 222.

[0061] In this embodiment, when the mold box 202 moves from the paper-feeding station a to the flaring station b, the primary folded cigarette pack 2 in the mold box 202 is in a stationary state. The flaring drive source drives the flaring four-bar linkage assembly 221 to work. The flaring four-bar linkage assembly 221 drives the flaring shaping plate 222 to swing towards the mold box 202. The flaring shaping plate 222 flares and shapes the inner left fold corner 12 and the inner right fold corner 11 of the primary folded cigarette pack 2. The inner left fold corner 12 and the inner right fold corner 11 form an "eight" shape, thereby forming the secondary folded cigarette pack 3 (e.g., ...). Figure 5 (As shown), then the flaring drive source drives the flaring shaping plate 222 to swing in the opposite direction and away from the mold box 202 through the flaring four-bar linkage assembly 221.

[0062] Preferred, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 As shown, an active corner bender 24 and a corner protection mechanism 25 are also provided on the outside of the smoke inlet station c. The reciprocating mold box mechanism 23 includes a reciprocating mold box drive source, a parallelogram component 231, and a transition mold box 232. The transition mold box 232 is set on the parallelogram component 231, and the reciprocating mold box drive source is connected to the parallelogram component 231. The transition mold box 232 is a hollow part, and the end of the transition mold box 232 away from the parallelogram component 231 is chamfered 233. The active corner bender 24 is set between the reciprocating mold box mechanism 23 and the wheel 201, and the corner protection mechanism 25 is set on the upper side of the active corner bender 24.

[0063] Furthermore, such as Figure 8As shown, the movable corner folder 24 includes a corner folding drive source, a rotating shaft, and a corner folding hook 241. The corner folding drive source is connected to the rotating shaft, and the corner folding hook 241 is located at the end of the rotating shaft away from the corner folding drive source. The corner folding hook 241 folds the right corner 11 of the inner package. The inner package protective plate 27 includes a first upper pressure plate 271, which is located between the corner protection mechanism 25 and the movable corner folder 24. The corner protection mechanism 25 includes a corner protection drive source, a corner protection four-bar linkage assembly 251, and a corner guard plate 252. The corner protection drive source is connected to the corner protection four-bar linkage assembly 251, and the corner guard plate 252 is located at the end of the corner protection four-bar linkage assembly 251. The first upper pressure plate 271 protects the top surface of the cigarette group 6 in the inner package, and the corner guard plate 252 maintains the folded state of the right corner 11 of the inner package.

[0064] In this embodiment, after the mold box 202 moves from the flaring station b to the cigarette feeding station c, the secondary folded cigarette pack 3 in the mold box 202 is in a stationary state. It is known that the cigarette pushing device in the upstream equipment conveys the cigarette group 6, and the cigarette group 6 is in the transition mold box 232. At this time, the reciprocating mold box drive source drives the transition mold box 232 to move into the secondary folded cigarette pack 3 through the parallelogram component 231. At the same time, the cigarette pushing device moves with the transition mold box 232. When the end chamfer 233 of the transition mold box 232 abuts against the inner left fold corner 12 and the inner right fold corner 11 respectively, keeping the inner left fold corner 12 and the inner right fold corner 11 in a "V" shaped flared state, the cigarette pushing device pushes the cigarette group 6 through the transition mold box 232 into the secondary folded cigarette pack 3.

[0065] After the cigarette pack 6 is fully pushed into the secondary folded cigarette pack 3, the reciprocating mold box drive source moves the transition mold box 232 away from the secondary folded cigarette pack 3, and the cigarette pushing device resets. Then, the corner drive source drives the corner hook 241 to rotate via the rotating shaft. The corner hook 241 folds the right corner 11 of the inner pack, and the right corner 11 of the inner pack folds towards the left corner 12 of the inner pack. When the corner hook 241 folds the right corner 11 of the inner pack to the correct position, the corner protection drive source drives the corner guard plate 252 downward to the front of the right corner 11 of the inner pack via the corner protection four-bar linkage assembly 251. The corner guard plate 252 shields and protects the right corner 11 of the inner pack, ensuring that the right corner 11 of the inner pack is in the correct folding position and will not rebound open. When the secondary folded cigarette pack 3 containing the cigarette pack 6 enters the next station, the corner protection drive source reverses the drive, and the corner hook 241 resets. In this embodiment, the corner hook can rotate 360°.

[0066] Preferred, such as Figure 1 , Figure 2 , Figure 8As shown, the first folding station d is located between the smoke inlet station c and the second folding station e; a fixed folding guide rail 26 is provided between the smoke inlet station c and the second folding station e, and the fixed folding guide rail 26 is mounted on the base; the fixed folding guide rail 26 includes a fixed folding plate 261 and a spiral folding plate 262. The fixed folding plate 261 is located between the smoke inlet station c and the first folding station d, and is used to fold the left fold corner 12 of the inner package while maintaining the folded state of the right fold corner 11 of the inner package; the spiral folding plate 262 is located between the first folding station d and the second folding station e. Between workstations e, a spiral folding groove is provided on the spiral folding plate 262, which folds the short front side 13 of the inner package; the inner package protective plate 27 also includes a second upper pressure plate 272 and a third upper pressure plate 273; the first upper pressure plate 271 and the second upper pressure plate 272 are both set on the top of the fixed folding plate 261, and the first upper pressure plate 271 is set upstream of the second upper pressure plate 272, and the third upper pressure plate 273 is set on the top of the spiral folding plate 262; the second upper pressure plate 272 and the third upper pressure plate 273 protect the top surface of the cigarette group 6 in the inner package. Furthermore, in this embodiment, the purpose of setting the first upper pressure plate 271, the second upper pressure plate 272, and the third upper pressure plate 273 is as follows: during the process of the inner package moving from the first folding station d to the second folding station e, neither the large inner package surface 15 nor the small inner package surface 14 is folded, and the upper surface of the cigarette group 6 is in an unprotected state. The cigarette group 6 is easily scattered or even thrown out of the mold box 202. Therefore, the first upper pressure plate 271, the second upper pressure plate 272, and the third upper pressure plate 273 are set to protect the upper surface of the cigarette group 6 and ensure that the arrangement of the cigarette group 6 does not change.

[0067] In this embodiment, both the fixed folding plate 261 and the spiral folding plate 262 are fixed to the base by a bracket.

[0068] When the inner package in the smoke inlet station c enters the first folding station d, the left folding corner 12 of the inner package is blocked by the fixed folding plate 261. The left folding corner 12 of the inner package folds towards the right folding corner 11 of the inner package. The right folding corner 11 of the inner package enters the fixed folding plate 261 from the corner guard plate 252 and always remains in the folded state.

[0069] When the inner package moves from the first folding station d to the second folding station e, the front short side 13 of the inner package enters the spiral folding groove on the spiral folding plate 262, which is opened at an angle upward. The front short side 13 of the inner package will fold upward towards the mold box 202, changing from a horizontal state to a vertical state.

[0070] Preferred, such as Figure 1 , Figure 2 , Figure 8As shown, the second folding station e is located between the flaring station b and the third folding station f. A large-area folding device 29 is also provided above the area between the flaring station b and the third folding station f. The large-area folding device 29 includes an inner arc plate 292 and an outer arc plate 291. The outer arc plate 291 is located between the flaring station b and the second folding station e. The inner arc plate 292 includes an inner arc segment 2922 and an inner spiral pressing segment 2921. The inner arc segment 2922 is located between the flaring station b and the second folding station e. The inner large-area 15 is secured between the inner arc segment 2922 and the outer arc plate 291. The inner spiral pressing segment 2921 is located between the second folding station e and the third folding station f, and is used to fold the inner large-area 15. Furthermore, the large-area folding device 29 is fixed above the base by a hanging plate, which is fixed to the base by a support rod.

[0071] In this embodiment, as the cardboard 1 moves from the flaring station b to the second folding station e, that is, as the primary folded cigarette pack 2 moves to the second folding station e, the inner packaging surface 15 is always vertically positioned between the inner arc segment 2922 and the outer arc plate 291, which support the inner packaging surface 15. When the cardboard 1 moves from the second folding station e to the third folding station f, the inner packaging surface 15 is only subjected to the action of the inner spiral pressing section 2921. The inner packaging surface 15 moves along the inner spiral pressing section 2921 and is pressed against the top of the mold box 202, ultimately forming an angle of 20-30° with the horizontal direction.

[0072] Preferred, such as Figure 1 , Figure 10 As shown, the movable folding device 28 is mounted on the base; the movable folding device 28 includes a lower shovel plate 282, an upper slap plate 284, a lower shovel plate drive assembly 281, and an upper slap plate drive assembly 283. The lower shovel plate drive assembly 281 is connected to the lower shovel plate 282 for folding the inner small face 14; the upper slap plate drive assembly 283 is connected to the upper slap plate 284 for folding the inner large face 15.

[0073] In this embodiment, when the inner package moves from the second folding station e to the third folding station f, the inner package's small facet 14 is in a vertical state, and the inner package's large facet 15 forms a 20-30° angle with the horizontal plane. The lower shovel drive assembly 281 drives the lower shovel 282 to move vertically towards the inner package's small facet 14, folding the top part of the inner package's small facet 14 from a vertical state to a horizontal state, pressing it above the inner package's left folding corner 12 and right folding corner 11. Then, the lower shovel drive assembly 281 drives the lower shovel 282 away from the inner package's small facet 14. Then, the upper shovel drive assembly 283 drives the upper shovel 284 to swing, and the upper shovel 284 swings downward to press the inner package's large facet 15 to a horizontal state. Then, the lower shovel drive assembly 281 again drives the lower shovel 282 to move vertically towards the inner package's small facet 14, pressing it onto the inner package's large facet 15 to prevent the inner package from rebounding and opening, forming a basic folded cigarette pack 4, as shown. Figure 6 As shown. After the inner package leaves the third folding station f, the lower shovel plate 282 resets, waiting for the next folding cycle.

[0074] Preferred, such as Figure 1 , Figure 2 As shown, a cigarette pack output channel 30 is provided on the outside of the output station g. A conveyor belt and an output folding device are installed in the cigarette pack output channel 30. The conveyor belt outputs the inner pack from the mold box 202. During the conveying process, the output folding device folds the left long side 16 and the right long side 17 of the inner pack. Further, in this embodiment, the left long side 16 and the right long side 17 of the inner pack are both part of the large surface 15 of the inner pack. The output folding device folds the left long side 16 and the right long side 17 of the inner pack on the basically folded cigarette pack 4 downwards, close to the two sides of the inner pack, forming the folded cigarette pack 5, as shown. Figure 7 As shown.

[0075] Preferred, such as Figure 1 , Figure 2 , Figure 8 As shown, the inner packaging production device also includes an empty station h. An empty station detection component 31 is installed on the outside of the empty station h to detect whether an inner package exists in the empty station h. In this embodiment, the empty station detection component 31 is a photoelectric detector 311. When the inner package is output from the mold box 202 by the cigarette pack output channel 30, the photoelectric detector 311 will detect that there is no cigarette pack in the mold box 202, and then the packaging wheel 20 will cycle into the next packaging cycle. If the photoelectric detector 311 detects that there is an inner package in the mold box 202, the packaging wheel 20 will stop rotating and the operator needs to troubleshoot the problem.

[0076] Furthermore, such as Figure 1 , Figure 2As shown, in this embodiment, the wheel 201 is circular, and its edge is designed with sixteen mold boxes 202, with two mold boxes 202 forming a group, totaling eight groups. This embodiment has eight workstations, with each group of mold boxes 202 corresponding to one workstation, and the distance between adjacent groups of mold boxes 202 is 45°. The angle between the paper-feeding workstation a and the cigarette-feeding workstation c is 90°, and the angle between the cigarette-feeding workstation c and the output workstation g is 180°. In other embodiments, the number of workstations can be a multiple of four and greater than six. In this embodiment, the two mold boxes 202 form a dual-route structure, therefore the corresponding paper-feeding mechanism 21, flaring mechanism 22, reciprocating mold box mechanism 23, movable corner folder 24, movable folder 28, cigarette pack output channel 30, and empty workstation detection component 31 are all dual-route structures.

[0077] Furthermore, the production packaging device is also equipped with a control system, which communicates with each mechanism in the aforementioned workstations to achieve automated control.

[0078] Furthermore, in this embodiment, the first upper pressure plate 271, the second upper pressure plate 272, and the third upper pressure plate 273 are all inner protective plates 27, used to apply pressure to the top surface of the cigarette pack 6 to ensure the arrangement order of the cigarette pack 6 in the inner packaging and prevent the cigarette pack 6 from being scattered.

[0079] Furthermore, in this embodiment, the packaging wheel drive source is a stepper motor. The corresponding parts for each station are arranged radially outward on the outer side of the wheel 201.

[0080] The apparatus for producing inner packaging of hard cigarettes according to the present invention comprises the following operating steps:

[0081] S1: The operator starts the packaging wheel 20 through the control system. The packaging wheel drive source works to drive the wheel disk 201 to rotate, and the mold box 202 on the wheel disk 201 enters the paper-feeding station a;

[0082] S2: When the mold box 202 enters the paper-feeding station a, the control system stops the rotation of the wheel 201, and the upstream paper transport equipment transports the cardboard 1 onto the mold box 202. The control system starts the paper-feeding drive source, which drives the paper-feeding board 212 to feed the cardboard 1 into the mold box 202 to form the primary folded cigarette pack 2. The inner packaging surface 15 is vertically positioned between the inner arc plate 292 and the outer arc plate 291. Then the paper-feeding drive source moves in the opposite direction, and the paper-feeding board 212 moves away from the mold box 202. The control system starts the wheel 201, and the primary folded cigarette pack 2 enters the flaring station b.

[0083] S3: When the primary folded cigarette pack 2 enters the flaring station b, the control system stops the rotation of the wheel 201, the flaring drive source works, and drives the flaring shaping plate 222 to move towards the mold box 202. The flaring shaping plate 222 flares and shapes the inner left fold 12 and inner right fold 11 of the primary folded cigarette pack 2, so that the inner left fold 12 and inner right fold 11 form an "eight" shape, thus forming the secondary folded cigarette pack 3. Then the flaring drive source drives the flaring shaping plate 222 away from the secondary folded cigarette pack 3. The control system starts the wheel 201, and the secondary folded cigarette pack 3 enters the cigarette inlet station c.

[0084] S4: When the secondary folded cigarette pack 3 enters the cigarette feeding station c, the control system stops the rotation of the wheel 201. The upstream cigarette pushing device pushes the cigarette group 6 through the transition mold box 232 into the secondary folded cigarette pack 3. During the cigarette pushing process, the reciprocating mold box drive source drives the transition mold box 232 to move towards the secondary folded cigarette pack 3. The chamfer 233 on the end face of the transition mold box 232 abuts against the left fold corner 12 and the right fold corner 11 of the inner pack to avoid the cigarette group 6 from colliding with the left fold corner 12 and the right fold corner 11 of the inner pack.

[0085] After the cigarette pushing is completed, the cigarette pushing device and transition mold box 232 are reset. The control system starts the corner folding drive source, which drives the corner folding hook 241 to rotate, and the corner folding hook 241 folds the right corner 11 of the inner pack. At the same time, the control system starts the corner protection drive source, which drives the corner protection plate 252 to move downward to block the right corner 11 of the inner pack, ensuring that the right corner 11 of the inner pack is in the folded state. The control system starts the wheel 201, and the secondary folded cigarette pack 3 containing the cigarette group 6 enters the first folding station d.

[0086] S5: During the process of the secondary folded cigarette pack 3 containing the cigarette group 6 entering the first folding station d, the fixed folding plate 261 between the cigarette entry station c and the first folding station d will collide with the left folding corner 12 of the inner pack and fold the left folding corner 12 of the inner pack. At the same time, the right folding corner 11 of the inner pack will disengage from the folding corner guard plate 252 and enter the fixed folding plate 261, and always remain in a folded state. At this time, the left folding corner 12 and the right folding corner 11 of the inner pack are in a folded state, and the front short side 13 of the inner pack is in a horizontal state.

[0087] S6: During the process of the secondary folded cigarette pack 3 moving from the first folding station d to the second folding station e, the front short side 13 of the inner pack enters the spiral folding groove of the spiral folding plate 262, and the front short side 13 of the inner pack moves along the spiral folding groove, folding from a horizontal state to a vertical state.

[0088] S7: During the process of the inner package moving from the flaring station b to the second folding station e, the inner package's large surface 15 remains vertical and moves along the gap between the inner arc plate 292 and the outer arc plate 291. When the inner package moves from the second folding station e to the third folding station f, the inner package's large surface 15 is only subjected to the action of the inner spiral pressing section 2921. The inner package's large surface 15 moves along the inner spiral pressing section 2921 and is pressed against the top of the mold box 202. Finally, the inner package's large surface 15 forms an angle of 20-30° with the horizontal direction.

[0089] S8: When the inner packaging reaches the third folding station f, the control system stops the rotation of the wheel 201 and starts the lower shovel drive assembly 281; the lower shovel drive assembly 281 drives the lower shovel 282 to move vertically towards the inner packaging facet 14, folding the top part of the inner packaging facet 14 from a vertical state to a horizontal state (e.g., ...). Figure 6 (As shown), then the lower shovel plate 282 is reset; the upper shovel plate drive assembly 283 is activated, and the upper shovel plate drive assembly 283 drives the upper shovel plate 284 to swing, and the upper shovel plate 284 swings downward to press the inner packaging surface 15 to a horizontal state; then the lower shovel plate drive assembly 281 is activated again, and the lower shovel plate drive assembly 281 drives the lower shovel plate 282 to press on the inner packaging surface 15 to prevent the inner packaging surface 15 from rebounding and opening.

[0090] S9: After the inner pack moves from the third folding station f to the output station g, the conveyor belt in the cigarette pack output channel 30 outputs the inner pack from the mold box 202. During the conveying process, the output folder folds the left long side 16 and the right long side 17 of the inner pack, thereby forming a hard cigarette inner pack. Figure 7 As shown.

[0091] S10: After the inner package is transported out of the mold box 202 through the cigarette pack output channel 30, the mold box 202 rotates to the empty station h. The empty station detection component 31 on the outside of the empty station h detects the empty station h. If there is an inner package in the empty station h, the control system stops the rotation of the wheel 201 and performs corresponding troubleshooting. If there is no inner package in the empty station h, the control system will drive the wheel 201 to rotate and enter the next packaging cycle.

[0092] The apparatus for producing inner packaging of hard cigarettes according to the present invention has the following beneficial effects:

[0093] 1. This invention features eight workstations that can orderly attach cigarette packs 6 (without any paper wrapping) to cardboard 1. During subsequent folding and movement, the specific arrangement of the cigarette packs 6 remains unchanged. Finally, the various folding mechanisms wrap the cigarette packs 6 inside the cardboard 1, forming a rigid cigarette inner pack. This results in a higher packaging speed, reaching 300 packs / minute, and more stable packaging quality.

[0094] 2. The present invention ensures that the cigarette assembly 6 can smoothly enter the rigid inner packaging through the dual action of the flaring mechanism 22 and the reciprocating mold box mechanism 23, thus protecting the cigarette head and solving the problem of cigarette damage caused by the combination of the cigarette assembly 6 and the rigid cardboard 1 in the existing equipment, and greatly improving the packaging quality of the inner packaging.

[0095] 3. The present invention adopts a dual-route (i.e., two mold boxes 202 are set as a group) to fold and package the rigid inner package. This can reduce the operating speed of all mechanisms such as pushing in the cigarette group 6, rotating the packaging wheel 20, and folding the cigarette package, while ensuring the production efficiency of the entire equipment.

[0096] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0097] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
