Description

Technical Field

[0001] This utility model relates to the field of cigarette production technology, and more specifically to an ironing device for transparent paper on irregularly shaped cigarette packs. Background Technology

[0002] The cartons of irregularly packaged cigarettes differ significantly from those of regular cigarettes in structure and rigidity. Using a mature machine-made transparent paper finishing device for these products often yields unsatisfactory results. Taking the YB95 transparent paper packaging machine as an example, in a conventional production process, cigarettes packaged upstream on the YB65 packaging machine exhibit high dimensional consistency. Due to their lower surface hardness, when wrapped in transparent paper and then shaped and ironed by the finishing device in the YB95 machine, the cigarettes undergo slight deformation within a range that does not affect product quality. This allows the transparent paper to fully contact the soldering iron's working surface, resulting in good performance. However, irregularly packaged cigarette cartons are mostly handmade, exhibiting dimensional differences in length, width, and height. Furthermore, the increased hardness of the auxiliary materials prevents the upper and lower soldering iron working surfaces of the finishing device from fully adhering to the product surface. This leads to situations where some areas of the transparent paper cannot be ironed, or even wrinkles appear on the remaining surfaces after ironing, severely impacting the product's appearance quality. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes an ironing device for the transparent paper of irregularly shaped cigarette packs, which is used to iron the transparent paper of the finished cigarette packs with irregular packaging, so as to ensure the appearance quality of the product after ironing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for ironing transparent paper on irregularly shaped cigarette packs, characterized by the following structural features: The irregularly shaped cigarette sticks with transparent paper to be ironed are rectangular; the device includes an upper soldering iron assembly, a side soldering iron assembly, and a lower soldering iron assembly for ironing the transparent paper on the four outer sides of the irregularly shaped cigarette sticks, and also includes a top soldering iron assembly and a bottom soldering iron assembly for ironing the transparent paper on the top and bottom surfaces of the irregularly shaped cigarette stick box. The upper soldering iron assembly is driven by an upper drive device to move the upper soldering iron and the upper connecting rod linearly back and forth between the initial position and the working position. Upon reaching the working position, the upper soldering iron, with its L-shaped working surface, presses against the outer surfaces of two adjacent sides of the shaped cigarette bar. The upper connecting rod, switching from the initial position to the working position, drives the side soldering iron assembly via a flipping mechanism to flip the side soldering iron from the initial position to the working position. The side soldering iron, upon reaching the working position, presses against one of the remaining two outer surfaces of the shaped cigarette bar, with its working surface adaptable. The lower soldering iron assembly is driven by a lower drive device to move the lower soldering iron linearly back and forth between the initial position and the working position. Upon reaching the working position, the lower soldering iron, with its working surface adaptable, presses against the outer surfaces of the shaped cigarette bar. Covering the remaining outer surface of the irregular cigarette pack; the top soldering iron of the top soldering iron assembly and the bottom soldering iron of the bottom soldering iron assembly share a side drive device, driven by the side drive device and transmitted through the translation linkage mechanism, causing the top soldering iron and the bottom soldering iron to move linearly back and forth between their respective initial positions and working positions. When the top soldering iron and the bottom soldering iron reach the working position, they respectively press against the top and bottom surfaces of the irregular cigarette pack box based on the working surface; the top soldering iron, side soldering iron, bottom soldering iron, top soldering iron and bottom soldering iron that reach the working position together complete the complete covering of the six sides of the irregular cigarette pack. When the top soldering iron, side soldering iron, top soldering iron and bottom soldering iron return to the initial position, they detach from the irregular cigarette pack, and the irregular cigarette pack can be supported by the bottom soldering iron based on the working surface.

[0005] The structural features of this utility model also lie in: The upper soldering iron assembly includes an upper drive device, an upper bracket, an upper connecting rod, and an upper soldering iron. The upper drive device is an electric lead screw that uses a servo motor to provide driving force, driving the upper bracket and the upper soldering iron mounted on the upper bracket to move back and forth linearly in sync with the upper connecting rod.

[0006] The side soldering iron assembly includes a side soldering iron and a flipping mechanism. The flipping mechanism includes a flipping shaft and a flipping lever. The flipping shaft can rotate around the central axis under the action of external force. The flipping lever and the side soldering iron are connected to the flipping shaft and located on opposite sides of the flipping shaft. The upper connecting rod, which switches from the initial position to the working position, touches and pushes the flipping lever. The flipping lever drives the flipping shaft to rotate, so that the side soldering iron swings around the central axis of the flipping shaft from the initial position to the working position.

[0007] The lower soldering iron assembly includes a lower drive device and a lower soldering iron. The lower drive device is an electric lead screw driven by a servo motor, which drives the lower soldering iron to move back and forth in a straight line between the initial position and the working position along the normal of the working surface. When the lower soldering iron is in the initial position, the outer side of the shaped cigarette bar and the corresponding side soldering iron is supported by the flip bearing extending out of the shaped cigarette bar. The working surface of the lower soldering iron in the working position is flush with the working surface of the side soldering iron in the initial position.

[0008] In the top and bottom soldering iron assemblies, the side drive device is an electric lead screw driven by a servo motor, and the translation linkage mechanism is a multi-bar component in the shape of an "U", including an L-shaped active link, a first link, a second link, and a third link. The short part of the L-shaped active link is connected to the electric lead screw, and the end of the long part of the L-shaped active link is hinged to one end of the first link through a first hinge shaft. The other end of the first link is hinged to one end of the second link through a second hinge shaft, and the other end of the second link is hinged to one end of the third link through a third hinge shaft. The first, second, and third hinge shafts are parallel to each other, and the other end of the third link is connected to the bottom soldering iron. The working surfaces of the top and bottom soldering irons face each other. Driven by the side drive device and transmitted through the translation linkage mechanism, the top and bottom soldering irons can move synchronously in opposite directions or in opposite directions.

[0009] The upper soldering iron assembly, side soldering iron assembly, lower soldering iron assembly, top soldering iron assembly, and bottom soldering iron assembly are mounted on the frame.

[0010] The working surface dimensions of the upper soldering iron, side soldering iron, and lower soldering iron are the same as the outer surface dimensions of the irregularly shaped cigarette pack being wrapped. The working surface dimensions of the top soldering iron and bottom soldering iron are the same as the top and bottom surfaces of the box containing the irregularly shaped cigarette pack being wrapped.

[0011] Compared with existing technologies, the beneficial effects of this utility model are reflected in: 1. This utility model is used to complete the overall one-time ironing and shaping of irregularly shaped cigarette strips. By heating and shaping the six sides of the irregularly shaped cigarette strip simultaneously, the problem of inconsistent quality of the transparent paper on each side of the cigarette strip is avoided, and the appearance quality of the product is effectively improved. 2. This utility model utilizes a servo motor to drive the actions of each soldering iron, which ensures the working accuracy of the device and allows for real-time adjustment, avoiding the need for repeated adjustments to the mechanical structure. 3. The device has a simple structure and is easy to install, making it suitable for the automated production of most irregularly shaped packaging and gift box products on the market.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please refer to Figures 1 to 4 The irregular cigarette bar transparent paper ironing device structure of this embodiment includes: The irregularly shaped cigarette stick 7, which is to be ironed with transparent paper, is rectangular; the device includes an upper soldering iron 12 assembly, a side soldering iron 23 assembly, and a lower soldering iron 32 assembly for ironing the transparent paper on the four outer sides of the irregularly shaped cigarette stick 7, and also includes a top soldering iron 41 assembly and a bottom soldering iron 410 assembly for ironing the transparent paper on the top and bottom surfaces of the irregularly shaped cigarette stick 7 box. The upper soldering iron 12 assembly is driven by the upper drive device 11 to move linearly back and forth between the initial position and the working position along with the upper connecting rod 13. Upon reaching the working position, the upper soldering iron 12, with its L-shaped cross-section, presses against the outer surfaces of two adjacent sides of the shaped tobacco strip 7. The upper connecting rod 13, switching from the initial position to the working position, drives the side soldering iron 23 assembly via a flipping mechanism to flip from the initial position to the working position. The side soldering iron 23, upon reaching the working position, presses against one of the remaining two outer surfaces of the shaped tobacco strip 7, with its working surface adapted to the working surface. The lower soldering iron 32 assembly is driven by the lower drive device 31 to move linearly back and forth between the initial position and the working position. Upon reaching the working position, the lower soldering iron 32, with its working surface adapted to the working surface, presses against the outer surface of the remaining side of the shaped tobacco strip 7. On the surface; the top soldering iron 41 of the top soldering iron 41 assembly and the bottom soldering iron 410 of the bottom soldering iron 410 assembly share a side drive device 42. Driven by the side drive device 42 and transmitted through the translation linkage mechanism, the top soldering iron 41 and the bottom soldering iron 410 move linearly back and forth between their respective initial positions and working positions. When the top soldering iron 41 and the bottom soldering iron 410 reach the working position, they respectively press against the top and bottom surfaces of the box of the shaped cigarette stick 7 in a matching manner with the working surface. The top soldering iron 12, the side soldering iron 23, the bottom soldering iron 32, the top soldering iron 41, and the bottom soldering iron 410, which reach the working position, jointly complete the complete coverage of the six sides of the shaped cigarette stick 7. When the top soldering iron 12, the side soldering iron 23, the top soldering iron 41, and the bottom soldering iron 410 return to the initial position, they detach from the shaped cigarette stick 7. The shaped cigarette stick 7 can always be supported by the bottom soldering iron 32 on the working surface.

[0016] In specific implementation, the corresponding structural settings of the shaped cigarette bar 7 transparent paper ironing device also include: The upper soldering iron 12 assembly includes an upper drive device 11, an upper bracket 14, an upper connecting rod 13, and an upper soldering iron 12. The upper drive device 11 is an electric lead screw 52 that uses a servo motor 51 to provide driving force, driving the upper bracket 14 and the upper soldering iron 12 mounted on the upper bracket 14 and the upper connecting rod 13 to move back and forth linearly in sync.

[0017] The side soldering iron 23 assembly includes the side soldering iron 23 and a flipping mechanism. The flipping mechanism includes a flipping shaft 21 and a flipping lever 22. The flipping shaft 21 can rotate around the central axis by external force. The flipping lever 22 and the side soldering iron 23 are connected to the flipping shaft 21 and are located on opposite sides of the flipping shaft 21. The upper connecting rod 13, which switches from the initial position to the working position, touches and pushes the flipping lever 22. The flipping lever 22 drives the flipping shaft 21 to rotate, so that the side soldering iron 23 swings around the central axis of the flipping shaft 21 from the initial position to the working position.

[0018] The lower soldering iron 32 assembly includes a lower drive device 31 and a lower soldering iron 32. The lower drive device 31 is an electric lead screw 52 that uses a servo motor 51 to provide driving force, driving the lower soldering iron 32 to move back and forth in a straight line between the initial position and the working position along the normal of the working surface. When the lower soldering iron 32 is in the initial position, the outer side of the shaped cigarette bar 7 and the corresponding side soldering iron 23 is supported by a flipping shaft 21 that extends out of the shaped cigarette bar 7. The working surface of the lower soldering iron 32 in the working position is flush with the working surface of the side soldering iron 23 in the initial position.

[0019] In the top soldering iron 41 assembly and the bottom soldering iron 410 assembly, the side drive device 42 is an electric lead screw 52 driven by a servo motor 51. The translation linkage mechanism is a multi-bar component in the shape of an "U", including an L-shaped active link 43, a first link 45, a second link 47, and a third link 49. The short part of the L-shaped active link 43 and the top soldering iron 41 are respectively connected to the electric lead screw 52. The end of the long part of the L-shaped active link 43 is hinged to one end of the first link 45 through a first hinge shaft 44. The other end of the first link 45... One end of the first connecting rod 44 is hinged to one end of the second connecting rod 47 via the second hinge shaft 46. The other end of the second connecting rod 47 is hinged to one end of the third connecting rod 49 via the third hinge shaft 48. The first hinge shaft 44, the second hinge shaft 46, and the third hinge shaft 48 are parallel to each other. The other end of the third connecting rod 49 is connected to the bottom soldering iron 410. The working surfaces of the top soldering iron 41 and the bottom soldering iron 410 face each other. Driven by the side drive device 42 and transmitted through the translation linkage mechanism, the top soldering iron 41 and the bottom soldering iron 410 can move synchronously in opposite directions or in opposite directions. The L-shaped active connecting rod 43 forms two adjacent sides of the "U" shape. The first connecting rod 45 and the second connecting rod 47 form the other side of the "U" shape. The third connecting rod 49 is used to connect the second connecting rod 47 and the bottom soldering iron 410.

[0020] The upper soldering iron 12 assembly, the side soldering iron 23 assembly, the lower soldering iron 32 assembly, the top soldering iron 41 assembly, and the bottom soldering iron 410 assembly are mounted on the frame 6.

[0021] The working surface dimensions of the upper soldering iron 12, the side soldering iron 23, and the lower soldering iron 32 are the same as the outer surface dimensions of the irregularly shaped cigarette pack 7. The working surface dimensions of the top soldering iron 41 and the bottom soldering iron 410 are the same as the outer surface dimensions of the top and bottom surfaces of the box containing the irregularly shaped cigarette pack 7.

[0022] The gap between the upper soldering iron 12 in its initial position and the rest of the lower structure is greater than the height of the irregular cigarette bar 7.

[0023] Each servo motor 51 can have its stroke, speed and other related parameters adjusted by an external electronic control system to achieve the purpose of simultaneous contact between the working surfaces of each soldering iron and the surface of the irregularly shaped smoke bar 7.

[0024] The lower soldering iron 32 is tilted, with its higher end smoothly connected to the cigarette output plane 8. It receives the irregular cigarette 7 from the upstream through the cigarette output plane 8. After the irregular cigarette 7 falls onto the working surface of the lower soldering iron 32 along the cigarette output plane 8, it tilts towards one side of the flip shaft 21 by its own weight until it abuts against the flip shaft 21.

[0025] This device can be installed at the cigarette dispensing position of irregularly shaped packaging equipment. Its operation process is as follows: In standby mode, the upper soldering iron 12 is raised to the initial position; when the shaped smoke bar 7 from upstream reaches the position of this device, it naturally tilts due to gravity, and the outer side of the shaped smoke bar 7 corresponding to the lower soldering iron 32 contacts the working surface of the lower soldering iron 32. At this time, the lower soldering iron 32 is in the initial position, and the outer side of the shaped smoke bar 7 corresponding to the side soldering iron 23 is blocked by the flipping shaft 21 and stops moving; then the device performs three actions respectively: Action 1: The upper drive device 11 operates, driving its electric lead screw 52 to rotate, which in turn drives the upper bracket 14 to move the upper soldering iron 12 and the upper connecting rod 13 downwards until the working surface of the upper soldering iron 12 contacts the outer surfaces of two adjacent sides of the irregularly shaped cigarette 7 facing it and applies slight pressure. When the upper connecting rod 13 moves downwards, it touches the flipping block 22, causing it to also move downwards. The flipping block 22 is fixedly connected to the flipping shaft 21 and the side soldering iron 23, so the side soldering iron 23 flips upwards and contacts the outer surface of one side of the irregularly shaped cigarette 7 facing it. Second, the side drive device 42 operates, driving its electric lead screw 52 to rotate, driving the active connecting rod and the top soldering iron 41 to move towards the top surface of the shaped cigarette bar 7, contacting the top surface of the shaped cigarette bar 7 and applying slight pressure; the active connecting rod, through the transmission of the first hinge shaft 44, the first connecting rod 45, the second hinge shaft 46, the second connecting rod 47, the third hinge shaft 48, and the third connecting rod 49, drives the bottom soldering iron 410 to also move towards the bottom surface of the shaped cigarette bar 7, contacting the bottom surface of the shaped cigarette bar 7 and applying slight pressure; Third, the lower soldering iron 32 moves from the initial position to the working position under the drive of the lower drive device 31, and its edge line coincides with the edge line of the side soldering iron 23. Together with other soldering irons, it completes the complete covering of the six sides of the irregular cigarette strip 7.

[0026] After all the above actions are completed, the upper drive device 11 and the side drive device 42 first reverse their actions, driving the upper soldering iron 12, the side soldering iron 23, the top soldering iron 41, and the bottom soldering iron 410 away from the irregular cigarette stick 7. At this time, the lower soldering iron 32 does not move. The irregular cigarette stick 7 falls along the working surface of the side soldering iron 23 under the action of gravity and enters the next process. After the irregular cigarette stick 7 is completely separated from the working surface of the side soldering iron 23, the lower drive device 31 drives the lower soldering iron 32 back to the initial position.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
