Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a cigarette pack transparent paper end heat sealing device and a cigarette pack shaping device. Background Technology

[0002] On cigarette packaging production lines, the transparent paper wrapping of the outer layer of cigarette packs is one of the key processes to ensure the product's appearance, moisture protection, and quality preservation. To ensure the transparent paper adheres tightly to the cigarette pack and forms a smooth, flat appearance, heat shrink forming technology is typically used. Currently, the core component of the cigarette pack forming equipment widely used in the industry is a relatively high-temperature flat soldering iron.

[0003] In existing technologies, a cam mechanism is typically used to drive the soldering iron to perform periodic, relative opening and closing movements. This clamps the cigarette pack to heat-seal its ends, achieving a smooth surface and a secure, aesthetically pleasing seal.

[0004] However, the motion curve of this traditional soldering iron based on cam control is fixed, making the equipment unable to flexibly adapt to cigarette packs of different sizes or transparent paper of different materials and thicknesses. Furthermore, the cam mechanism has poor stability, generating significant inertial forces and impacts at high speeds. This not only leads to high equipment noise but also accelerates wear and tear on the mechanism itself, requiring frequent maintenance and replacement, thus increasing the long-term operating costs of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a hot-sealing device for the end of the transparent paper of a cigarette pack and a cigarette pack shaping equipment. The hot-sealing device for the end of the transparent paper of a cigarette pack can hot-seal cigarette packs of different sizes and has good stability.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, a hot-sealing device for the end of the transparent paper of a cigarette pack is provided, comprising:

[0008] A shaping mechanism, wherein the shaping mechanism is provided with a conveying channel;

[0009] Two hot-sealing soldering irons are arranged parallel to each other along a first direction on one side of the shaping mechanism, and a hot-sealing channel is formed between the two hot-sealing soldering irons. The hot-sealing channel is arranged correspondingly to the conveying channel.

[0010] The device includes a drive motor and two parallel four-bar linkages. Each parallel four-bar linkage corresponds to a hot-sealing soldering iron and is connected to the side of the hot-sealing soldering iron facing away from the hot-sealing channel. The drive motor drives the two parallel four-bar linkages to swing in a second direction toward each other or away from each other.

[0011] Optionally, the hot-sealing device for the end of the transparent paper of the cigarette pack further includes two connecting rods, which correspond one-to-one with the parallel four-bar linkage. The first end of the connecting rod is hinged to the output shaft of the drive motor. The parallel four-bar linkage includes an upper connecting rod, a lower connecting rod, a left connecting rod, and a right connecting rod. One of the left connecting rod and the right connecting rod is hinged to the second end of the connecting rod. The hot-sealing soldering iron is connected to the upper connecting rod.

[0012] Optionally, the hot-sealing soldering iron is provided with a pre-sealing part and a hot-sealing part in sequence along the first direction, and the pre-sealing part is located on the side of the hot-sealing soldering iron closer to the shaping mechanism.

[0013] Optionally, the hot-sealing device for the end of the transparent paper of the cigarette pack further includes a guide assembly, which includes a placement platform and two guide plates. The placement platform is located below the hot-sealing iron and corresponds to the hot-sealing channel. The guide plates are arranged one-to-one with the pre-sealed parts and are located on opposite sides of the two pre-sealed parts.

[0014] Optionally, a pre-sealing block is provided on each of the two pre-sealing portions on opposite sides, and the guide plate is provided with a clearance hole for avoiding the pre-sealing block.

[0015] Optionally, the shaping mechanism includes two folding plates, which are parallel and spaced apart along the second direction.

[0016] Optionally, the shaping mechanism further includes two first connecting plates, two second connecting plates, and at least two elastic elements. The two first connecting plates are parallel to each other along the second direction and spaced apart, and are located above the folding plate. The folding plate, the second connecting plate, and the first connecting plate correspond one-to-one. The second connecting plate is connected to the first connecting plate through at least one of the elastic elements.

[0017] Optionally, the first connecting plate is provided with a limiting part, and the side of the second connecting plate facing away from the first connecting plate can abut against the limiting part.

[0018] Optionally, the cigarette pack transparent paper end heat sealing device further includes a mounting plate, the mounting plate having a reference plane, and the drive motor and the two parallel four-bar linkages are all mounted on the reference plane.

[0019] On the other hand, a cigarette pack shaping device is provided, including a cigarette pushing mechanism and the aforementioned cigarette pack transparent paper end heat sealing device. The cigarette pushing mechanism is located on the side of the shaping mechanism facing away from the heat sealing iron, and the cigarette pushing mechanism can push the cigarette pack from the conveying channel into the heat sealing channel.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a hot-sealing device for the ends of transparent paper in cigarette packs and a cigarette pack shaping device. The hot-sealing device for the ends of transparent paper in cigarette packs includes a shaping mechanism, two hot-sealing irons, a drive motor, and two parallel four-bar linkages. A conveying channel is provided on the shaping mechanism. The two hot-sealing irons are spaced apart and parallel to each other along a first direction on one side of the shaping mechanism, forming a hot-sealing channel between them. The hot-sealing channel corresponds to the conveying channel. Each parallel four-bar linkage corresponds to one of the hot-sealing irons and is connected to the side of the hot-sealing iron facing away from the hot-sealing channel. The drive motor drives the two parallel four-bar linkages, which can drive the two parallel four-bar linkages to swing in a second direction, moving closer to or further away from each other. This causes the two hot-sealing irons connected to the two parallel four-bar linkages to move closer to or further away from each other, thus performing an opening and closing motion. When not hot-sealed, the two hot-sealing irons are in an open state. When the cigarette pack is conveyed to the hot-sealing channel, the two hot-sealing irons approach each other and abut against both ends of the cigarette pack to hot-seal both ends. By driving the hot-sealing iron with a parallel four-bar linkage, the iron can be ensured to move along the second direction, improving its stability and thus enhancing the hot-sealing effect on the cigarette pack. This also extends the lifespan of the hot-sealing device at the end of the cigarette pack's transparent paper. The parallel four-bar linkage can be oscillated by a drive motor, controlling its oscillation angle and consequently the distance between the two hot-sealing irons during sealing, allowing for the sealing of cigarette packs of different sizes. The drive motor can also control the oscillation rate of the parallel four-bar linkage, adjusting the sealing time for the cigarette pack to allow for different sealing times on transparent paper of different materials and thicknesses, further improving the sealing effect.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1 As shown, this embodiment provides a hot-sealing device for the end of the transparent paper of a cigarette pack. The hot-sealing device for the end of the transparent paper of a cigarette pack includes a shaping mechanism 1, two hot-sealing irons 2, a drive motor 3, and two parallel four-bar linkages 4. The shaping mechanism 1 is provided with a conveying channel, and the shaped cigarette pack 100 is conveyed into the conveying channel. The two hot-sealing irons 2 are spaced apart and parallel to each other along a first direction on one side of the shaping mechanism 1, forming a hot-sealing channel between the two hot-sealing irons 2. The hot-sealing channel is correspondingly arranged with the conveying channel. The parallel four-bar linkages 4 correspond one-to-one with the hot-sealing irons 2 and are connected to the side of the hot-sealing irons 2 facing away from the hot-sealing channel. The drive motor 3 drives the two parallel four-bar linkages 4 to swing along a second direction in a direction that moves closer to or further away from each other, thereby causing the two hot-sealing irons 2 connected to the two parallel four-bar linkages 4 to move in a direction that moves closer to or further away from each other, that is, the two hot-sealing irons 2 perform opening and closing movements. Before sealing, both sealing irons 2 are in the open state. When the cigarette pack 100 is conveyed to the sealing channel, the two sealing irons 2 approach each other and abut against both ends of the cigarette pack 100 to seal the ends of the cigarette pack 100. Specifically, the first direction is... Figure 1 The X direction in the middle, the second direction is Figure 1 In the Y direction, the first direction is perpendicular to the second direction.

[0039] The parallel four-bar linkage 4 drives the hot-sealing iron 2 to move, ensuring that the hot-sealing iron 2 moves along the second direction, improving the stability of the hot-sealing iron 2 during movement, thereby improving the hot-sealing effect on the cigarette pack 100. It also extends the service life of the hot-sealing device at the end of the cigarette pack's transparent paper. The drive motor 3 drives the parallel four-bar linkage 4 to swing, controlling the swing angle of the linkage 4, thus controlling the distance between the two hot-sealing irons 2 during hot-sealing, allowing for hot-sealing of cigarette packs 100 of different sizes. The drive motor 3 can also control the swing speed of the parallel four-bar linkage 4, thereby adjusting the hot-sealing time of the hot-sealing iron 2 on the cigarette pack 100, allowing for different sealing times for transparent paper of different materials and thicknesses, further improving the hot-sealing effect.

[0040] Optionally, the hot-sealing device for the end of the transparent paper of the cigarette pack also includes a mounting plate 7. The mounting plate 7 has a reference plane, and the drive motor 3 and two parallel four-bar linkages 4 are all mounted on the reference plane to improve the swing accuracy of the two parallel four-bar linkages 4, thereby improving the hot-sealing effect of the hot-sealing iron 2 on the cigarette pack 100.

[0041] Optionally, such as Figure 1 and Figure 2As shown, the hot-sealing device for the end of the cigarette pack's transparent paper also includes two connecting rods 5, each corresponding to a parallel four-bar linkage 4. The first end of the connecting rod 5 is hinged to the output shaft of the drive motor 3. The parallel four-bar linkage 4 includes an upper connecting rod 41, a lower connecting rod 42, a left connecting rod 43, and a right connecting rod 44. One of the left connecting rod 43 and the right connecting rod 44 is hinged to the second end of the connecting rod 5. The hot-sealing soldering iron 2 is connected to the upper connecting rod 41. The rotation of the output shaft of the drive motor 3 causes the connecting rod 5 to swing, thereby causing the left connecting rod 43 and the right connecting rod 44 to swing, which in turn causes the hot-sealing soldering iron 2 to move along the second direction.

[0042] Specifically, a turntable 8 is fixedly connected to the output shaft of the drive motor 3. The first ends of the two connecting rods 5 are respectively hinged to the opposite sides of the turntable 8 about the center. The upper connecting rod 41, the lower connecting rod 42, the left connecting rod 43 and the right connecting rod 44 are hinged in sequence. The lower connecting rod 42 is fixedly connected to the mounting plate 7, and the second ends of the two connecting rods 5 are hinged to the left connecting rod 43.

[0043] Optionally, such as Figure 1 and Figure 3 As shown, the hot-sealing iron 2 is provided with a pre-sealing part 21 and a hot-sealing part 22 along the first direction. The pre-sealing part 21 is located on the side of the hot-sealing iron 2 closest to the shaping mechanism 1. The pre-sealing part 21 is used to pre-seale the cigarette pack 100, fixing the transparent paper on the outside of the cigarette pack 100 to prevent the transparent paper from coming apart. The hot-sealing part 22 fully seals the fixed transparent paper, improving the firmness of the transparent paper and making the transparent paper flat and beautiful.

[0044] Specifically, two heat-sealing sections 22 are provided, arranged sequentially along the first direction. By using two heat-sealing sections 22 to perform two full heat-sealing operations on the transparent paper, the heat-sealing effect on the transparent paper is improved. The pre-sealing section 21 is a high-temperature flat soldering iron, whose working temperature is adjusted by a control component. The heat-sealing section 22 is a hot air soldering iron, which has ventilation holes. Hot air is blown into the ventilation holes to heat-seal the transparent paper. The specific structure of the hot air soldering iron is similar to that of the prior art, and will not be described in detail in this application.

[0045] Optionally, such as Figure 1 , Figure 3 and Figure 4 As shown, the hot-sealing device for the end of the cigarette pack's transparent paper also includes a guide assembly 6. The guide assembly 6 includes a placement platform 61 and two guide plates 62. The placement platform 61 is located below the hot-sealing iron 2 and corresponds to the hot-sealing channel. The placement platform 61 is used to place the cigarette pack 100. The guide plates 62 are arranged one-to-one with the pre-sealing sections 21 and are located on opposite sides of the two pre-sealing sections 21. The guide assembly can block the transparent paper on both sides of the cigarette pack 100 after folding but not hot-sealed, preventing the transparent paper from spreading out after folding and affecting the hot-sealing effect.

[0046] Specifically, the guide plate 62 is vertically positioned and adjustable in the second direction above the placement platform 61 to accommodate cigarette packs 100 of different sizes. In another embodiment, two placement platforms 61 are provided, with the guide plate 62 corresponding to and fixedly connected to each placement platform 61, and the two placement platforms 61 are adjustable in the second direction.

[0047] Optionally, each of the two pre-sealing sections 21 has a pre-sealing block 211 on one side opposite to the other. The pre-sealing block 211 is used to heat-seal the transparent paper. The guide plate 62 is provided with a clearance hole 621 to avoid the pre-sealing block 211. The pre-sealing block 211 can pass through the clearance hole 621 and abut against the cigarette pack 100 to pre-seal the transparent paper. Specifically, the clearance hole 621 has the same shape as the pre-sealing block 211, and the size of the clearance hole 621 is slightly larger than the size of the pre-sealing block 211 to ensure that the pre-sealing block 211 can pass through smoothly. In this embodiment, the side of the pre-sealing block 211 facing the cigarette pack 100 is a rectangular plane.

[0048] Optionally, such as Figure 1 and Figure 5 As shown, the shaping mechanism 1 includes two folding plates 14, which are parallel and spaced apart along a second direction. The two folding plates 14 are capable of folding the transparent paper at the end of the cigarette pack 100. The specific structure of the folding plates 14 is consistent with the prior art, and will not be described in detail in this application.

[0049] Optionally, the shaping mechanism 1 further includes two first connecting plates 11, two second connecting plates 12, and at least two elastic elements 13. The two first connecting plates 11 are parallel and spaced apart along a second direction and located above the folding plate 14. The folding plate 14, the second connecting plates 12, and the first connecting plates 11 correspond one-to-one. The second connecting plates 12 are connected to the first connecting plates 11 by at least one elastic element 13. A conveying channel is formed between the two second connecting plates 12. After the transparent paper is folded, the cigarette pack 100 is conveyed between the two second connecting plates 12. The cigarette pack 100 presses against the two second connecting plates 12, causing the two second connecting plates 12 to abut against the ends of the cigarette pack 100, preventing the folded transparent paper from unraveling. The cigarette pack 100 is then conveyed between the guide plates 62.

[0050] Specifically, the shaping mechanism 1 also includes a support frame 16. A first connecting plate 11 is fixedly connected to the support frame 16. The first connecting plate 11 and the second connecting plate 12 have the same shape and size. The bottom end of the second connecting plate 12 is rotatably connected to the bottom end of the first connecting plate 11. Elastic members 13 are disposed on the upper side of the second connecting plate 12 and the first connecting plate 11, causing the upper side of the first connecting plate 11 to tilt towards each other. Six elastic members 13 are provided, with three elastic members 13 spaced apart along a first direction between each second connecting plate 12 and the first connecting plate 11. The elastic members 13 can be springs.

[0051] Optionally, a limiting part 111 is provided on the first connecting plate 11, and the side of the second connecting plate 12 facing away from the first connecting plate 11 can abut against the limiting part 111. The limiting part 111 can restrict the position of the second connecting plate 12 and improve the stability of the second connecting plate 12. Specifically, the limiting part 111 is provided at the top of the first connecting plate 11 and extends to the side of the second connecting plate 12 facing away from the first connecting plate 11. When there is no cigarette pack 100 between the two second connecting plates 12, the side of the second connecting plate 12 facing away from the first connecting plate 11 abuts against the limiting part 111; when there is a cigarette pack 100 between the two second connecting plates 12, the cigarette pack 100 pushes the second connecting plate 12 to rotate, causing the elastic member 13 to compress.

[0052] Optionally, the shaping mechanism 1 further includes a limiting plate 15, which is connected to the support frame 16 and located on the side of the first connecting plate 11 facing away from the hot-sealing soldering iron 2. The limiting plate 15 is arranged horizontally, and the cigarette pack 100 is conveyed from below the limiting plate 15 to between the two folding plates 14. The limiting plate 15 can restrict the position of the cigarette pack 100, thereby stabilizing the cigarette pack 100 and improving the folding effect of the transparent paper at the end of the cigarette pack 100.

[0053] This embodiment also provides a cigarette pack shaping device. The cigarette pack shaping device includes a cigarette pushing mechanism and the aforementioned hot-sealing device for the transparent paper end of the cigarette pack. The cigarette pushing mechanism is located on the side of the shaping mechanism 1 facing away from the hot-sealing iron 2. The cigarette pushing mechanism can push the cigarette pack 100 from the conveying channel into the hot-sealing channel to hot-seal the cigarette pack 100. The cigarette pack shaping device can improve the stability of the hot-sealing iron 2 during movement, thereby improving the hot-sealing effect on the cigarette pack 100, and can hot-seal cigarette packs 100 of different sizes.

[0054] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
