[0031] As Figure 1 shown, the cigarette pack transparent film folding device of this embodiment includes a folding channel 10 and a lifting channel 20.
[0032] The folding channel 10 includes a cigarette pack conveying part for conveying the cigarette pack 8, a corner folder 6 provided at the end in the width direction of the cigarette pack conveying part, and a spiral folder 5. The corner folder 6 is configured to fold the first side d of the transparent film extending from the end of the cigarette pack 8, which is located at the downstream end in the moving direction of the cigarette pack 8, towards the end face of the cigarette pack 8. The spiral conveyor 5 has a spiral surface, and the spiral surface is configured to gradually fold the bottom surface e of the transparent film upwards as the cigarette pack 8 moves so that the bottom surface e adheres to the end face of the cigarette pack 8.
[0033] The lifting channel 20 is arranged at the downstream end of the cigarette packet conveying part and is connected to the cigarette packet conveying part. The lifting channel 20 is configured to lift the cigarette packet 8 upward, so as to fold the top surface f of the transparent film downward, and attach the top surface f to the end face of the cigarette packet 8.
[0034] In this embodiment, the corner folding device 6 folds the first side surface d of the transparent film extending from the end of the cigarette packet 8, which is located at the downstream end in the moving direction of the cigarette packet 8, toward the end face of the cigarette packet 8. The spiral surface of the spiral conveyor 5 is configured to gradually fold the bottom surface e of the transparent film upward as the cigarette packet 8 moves, so that the bottom surface e is attached to the end face of the cigarette packet 8. The corner folding device 6 and the spiral folding device 5 cooperate with each other to fold the bottom surface e of the transparent film upward, and the top surface f of the transparent film in the lifting channel 20 is folded downward, which improves the problem of poor folding in the folding process of the transparent film of the medium-sized cigarette packet existing in the prior art.
[0035] See Figure 3 , the corner folding device 6 is provided with an inclined surface 61, and the distance between the inclined surface 61 and the center in the width direction of the cigarette packet conveying part gradually decreases from upstream to downstream along the moving direction of the cigarette packet 8, so that the first side surface d is gradually attached to the end face of the cigarette packet 8.
[0036] In some embodiments, the cigarette packet transparent film folding device further includes a limiting member 7. The limiting member 7 includes a first limiting surface parallel to the cigarette packet conveying part, so that the cigarette packet 8 is attached to the cigarette packet conveying part.
[0037] In some embodiments, the limiting member 7 is further provided with a second limiting surface for guiding the lifting of the cigarette packet 8. The second limiting surface is configured to limit the movement of the cigarette packet 8 along the extending direction of the cigarette packet conveying part during the lifting process.
[0038] See Figure 4 , the limiting member 7 includes a first plate-like member 71 covering the upper part of the cigarette packet conveying part and a second plate-like member 72 erected on the first plate-like member 71. The first limiting surface is formed on the bottom surface of the first plate-like member 71, and the second limiting surface is formed on the vertical side surface of the second plate-like member 72.
[0039] The cigarette packet transparent film folding device further includes a heating part arranged above the lifting channel 8. The heating part includes a heating channel connected to the lifting channel 20. Heating components 1 are respectively arranged on both sides of the heating channel. The lifting channel 20 is surrounded by two relatively arranged fixing plates 3. The two heating components 1 are respectively connected to the two fixing plates 3, and a heat insulation component 2 is arranged between the heating component 1 and the fixing plate 3.
[0040] In some embodiments, it further includes two relatively arranged bases 4. The cigarette packet conveying part and the lifting channel 20 are both located between the two bases 4, and the two fixing plates 3 are respectively installed on the two bases 4.
[0041] A corner folder 6 and a spiral folder 5 are installed inside each base 4 to fold the transparent films at both ends of the cigarette pack 8 respectively.
[0042] The transparent film folding device of this embodiment is used to fold the transparent film at the end of the small box cigarette pack 8 of medium size. In some embodiments, it is used for the cigarette pack of medium-width version.
[0043] The small glass end folding and lifting device of the medium-width packaging machine is composed of a small glass end folding channel 10, a stacking channel (lifting channel) and an end heating (heating part). The above-mentioned small glass end refers to the glass paper (transparent film) at the end of the small box cigarette.
[0044] The corner folders 6 and the spiral folders 5 at both ends in the width direction of the folding channel 1 are respectively used for folding the top transparent film and the bottom transparent film of the cigarette pack. The corner folders 6 and the spiral folders 5 can fold the bottom surface e of the end transparent film of the cigarette pack 8 by 90 degrees.
[0045] The stacking channel is composed of two fixed plates 3 arranged oppositely. When the cigarette pack 8 is lifted, the top surface f of the transparent film of the cigarette pack 8 is folded. At the same time, the fixed plate 3 plays a role in fixing the corner folder 6.
[0046] The end heating is composed of top heating and bottom heating. Among them, the heating part includes two heating components arranged oppositely, and the two heating components respectively heat the transparent films at the top and bottom of the cigarette pack.
[0047] The limiting components play two roles. One is that the bottom surface of the limiting component 7 plays a limiting role during the folding process, and the other is that the right side surface of the limiting component 7 plays a limiting role during the stacking process. The two limiting components 7 are respectively fixedly connected to the two fixed plates 3. The base 4 plays a role of fixed support. Among them, the two bases 4, the two fixed plates 3, the two heat insulation plates 2 and the two heating components 1 are arranged in one-to-one correspondence, and the base 4 is fixedly connected to the corresponding fixed plate 3, heat insulation plate 2 and heating component 1.
[0048] The stacking channel is composed of a fixed plate 13 and a fixed plate 23. When the cigarette pack 8 is lifted, the folding of the upper bottom edge of the small glass end is completed. At the same time, the fixed plate 13 plays a role in fixing the corner folder 16, and the fixed plate 23 plays a role in fixing the corner folder 26.
[0049] The cigarette pack 8 enters the small glass end folding and lifting device from the left side. The combination of the spiral folder 5 and the corner folder 6 folds the bottom surface e of the transparent film of the cigarette pack 8 upward by 90°. The cigarette pack 8 continues to move forward. The upward lifting movement of the cigarette pack completes the folding of the other long sides at the bottom and top, and then completes the preliminary preheating and sealing at the heating component 1.
[0050] In some embodiments, in combination with Figure 1 and Figure 2, the cigarette pack transparent film folding device of this embodiment further includes a movable folding corner device disposed upstream of the folding channel 10 for folding the second side c of the transparent film extending from the end of the cigarette pack 8, which is located at the upstream end in the moving direction of the cigarette pack 8, towards the end face of the cigarette pack 8.
[0051] Before the cigarette pack 8 and the transparent film enter the above-mentioned folding channel 10, the movable folding corner device folds the second side c of the transparent film at both ends of the cigarette pack 8 towards the end face of the cigarette pack 8. Then, the cigarette pack 8 and the transparent film enter the above-mentioned folding channel 10. Folding corner devices 6 and spiral folding devices 5 are provided at both ends of the folding channel 10. The folding corner device 6 folds the first side d of the transparent film extending from the end of the cigarette pack 8, which is located at the downstream end in the moving direction of the cigarette pack 8, towards the end face of the cigarette pack 8. The spiral surface of the spiral conveyor 5 is configured to gradually fold the bottom surface e of the transparent film upwards as the cigarette pack 8 moves so that the bottom surface e adheres to the end face of the cigarette pack 8. The folding corner device 6 and the spiral folding device 5 cooperate with each other to fold the bottom surface e of the transparent film upwards and fold the top surface f of the transparent film in the lifting channel 20 downwards. Subsequently, the cigarette pack and the folded transparent film enter the heating channel, and the heating components at both ends of the heating channel heat and shape the transparent films at both ends of the cigarette pack 8 respectively.
[0052] According to another aspect of the present invention, a packaging machine is also provided, and this packaging machine includes the above-mentioned cigarette pack transparent film folding device.
[0053] The above are only exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
