[0002] During the cigarette production process, the transparent paper wrapping small cigarette boxes is primarily used to prevent the loss of cigarette odor and retain moisture, ensuring the taste of the cigarette products. However, during the actual packaging process, quality defects such as fluffy, wrinkled, loosely ironed, and poorly sealed transparent paper can occur. The folded overlaps of the transparent paper at the top and bottom of the cigarette pack are heat-sealed by the top and bottom irons within the packaging machine's output channel.

[0003] However, the existing heat sealing device cannot completely heat seal the two layers of transparent paper on the top and bottom of the cigarette pack. Moreover, due to the aging of the equipment, when the machine runs at high speed, the movable base does not have enough force to drive the two vertical soldering irons to heat seal, resulting in the two vertical soldering irons failing to contact the top and bottom transparent paper of the cigarette pack, resulting in poor heat sealing effect, loose ironing, and poor sealing.

[0004] Therefore, how to provide a heat-sealing device for the ends of transparent paper of cigarette packages has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0025] like Figure 1 As shown, an embodiment of the present invention provides a device for heat-sealing the end of a transparent paper of a cigarette pack, comprising: a fixed base 1, a cigarette pack conveying component 2, two soldering irons 3 and a control component 4.

[0026] The soldering irons 3 are respectively arranged on both sides of the top of the fixed base 1, and a cigarette pack conveying channel is formed between the two soldering irons 3; the cigarette pack conveying assembly 2 is used to convey the cigarette packs into the cigarette pack conveying channel. The height of the soldering irons 3 is greater than the height of two layers of cigarette packs, and the minimum distance between the two soldering irons 3 is less than the length of the cigarette pack.

[0027] Specifically, since the height of the soldering iron 3 is greater than the height of the two layers of cigarette packs, the soldering iron 3 can heat-seal the transparent paper on the top and bottom of the two layers of cigarette packs.

[0028] The control assembly 4 includes a driving cylinder (not shown in the figure) and a fixing plate 41. The fixing plates 41 are respectively arranged outside the soldering iron 3 and connected to the soldering iron 3. The driving cylinder is connected to the fixing plate 41 and is used to drive the fixing plate 41 to move horizontally.

[0029] Specifically, the driving cylinder drives the fixed plate 41 to move, thereby driving the soldering iron 3 to move, so that there is a minimum distance and a maximum distance between the two soldering irons 3, and the minimum distance between the two soldering irons 3 is less than the length of the cigarette pack, so that the two soldering irons 3 can completely heat-seal the top and bottom of the two layers of cigarette packs.

[0030] It should be noted that the driving cylinder operates in a reciprocating motion, thereby driving the fixed plate 41 and the soldering irons 3 to reciprocate. Furthermore, when the cigarette pack conveying assembly 2 conveys cigarette packs into the cigarette pack conveying channel, the driving cylinder drives the two soldering irons 3 to move toward each other (i.e., the two soldering irons 3 move toward the inside of the cigarette pack conveying channel to narrow the width of the cigarette pack conveying channel). Once heat sealing is complete, the driving cylinder drives the two soldering irons 3 to move away from each other (i.e., the two soldering irons 3 move toward the outside of the cigarette pack conveying channel to widen the cigarette pack conveying channel).

[0031] During use, when the cigarette pack conveying component 2 conveys the cigarette pack into the cigarette pack conveying channel, the driving cylinder starts to work, and the driving cylinder drives the fixed plate 41 to move, and the movement of the fixed plate 41 drives the soldering iron 3 to move, so that the two soldering irons 3 move toward the inside of the cigarette pack conveying channel, and then heat-seal the top and bottom transparent paper of the cigarette pack, and can completely heat-seal the top and bottom of the two layers of cigarette pack; when the heat sealing is completed, the driving cylinder drives the two soldering irons 3 to move toward the outside of the cigarette pack conveying channel, so that the soldering iron 3 does not heat-seal the cigarette pack, thereby avoiding the soldering iron 3 over-heat-sealing the top and bottom transparent paper of the cigarette pack, causing the transparent paper to wrinkle and be damaged.

[0032] The present invention arranges the soldering irons 3 on both sides of the top of the fixed base 1 relative to each other, forming a cigarette pack conveying channel between the two soldering irons 3, wherein the height of the soldering irons 3 is greater than the height of the two layers of cigarette packs, and the minimum distance between the two soldering irons 3 is less than the length of the cigarette packs; and the fixing plates 41 are respectively arranged outside the soldering irons 3 and connected to the soldering irons 3, and the driving cylinder is connected to the fixing plates 41. During use, when the cigarette pack conveying assembly 2 conveys the cigarette packs into the cigarette pack conveying channel, the driving cylinder starts to work, driving the fixing plates 41 to move, and the movement of the fixing plates 41 drives the soldering irons 3 to move, thereby heat-sealing the transparent paper on the top and bottom of the cigarette packs, and can completely heat-seal the top and bottom of the two layers of cigarette packs, thereby improving the heat-sealing effect, avoiding the problem of the transparent paper on the top and bottom of the cigarette packs being loosely ironed and having poor sealing, and effectively improving work efficiency.

[0033] In one embodiment of the heat-sealing device for the transparent paper end of a cigarette pack of the present invention, a slide plate 5 is further provided on the top of the fixed base 1 , and two soldering irons 3 are provided on both sides of the slide plate 5 .

[0034] The utility model provides a slide plate 5 on the top of the fixed base 1 and arranges two soldering irons 3 on both sides of the slide plate 5, so that the cigarette pack can move smoothly and quickly in the cigarette pack conveyor, effectively improving the heat sealing efficiency of the cigarette pack and further avoiding the problem of damage to the transparent paper caused by the long heat sealing time of the cigarette pack.

[0035] In one embodiment of the heat-sealing device for the transparent paper ends of cigarette packs of the present invention, the control component 4 also includes a support plate 42, a fixing rod 43 and a spring 44. The support plates 42 are respectively arranged on both sides of the cigarette pack conveying channel, and the first end of the support plate 42 is arranged on the packaging machine frame, the second end of the support plate 42 is connected to the fixing plate 41, the first end of the fixing rod 43 is connected to the support plate 42, and the two ends of the spring 44 are respectively connected to the second end of the fixing rod 43.

[0036] Specifically, when the cigarette pack conveying assembly 2 conveys the cigarette pack into the cigarette pack conveying channel, the driving cylinder starts working, and the driving cylinder drives the fixed plate 41 to move. The movement of the fixed plate 41 drives the soldering iron 3 and the support plate 42 to move, so that the two soldering irons 3 and the support plate 42 move toward the inside of the cigarette pack conveying channel, and then heat-seal the top and bottom transparent paper of the cigarette pack, and can completely heat-seal the top and bottom of the two layers of cigarette pack. At this time, the spring 44 is in a compressed state.

[0037] When heat sealing is completed, the driving cylinder is powered off. At this time, the spring 44 recovers its elastic deformation and drives the soldering iron 3 and the support plate 42 to move toward the outside of the cigarette pack conveying channel, thereby preventing the soldering iron 3 from heat sealing the cigarette pack.

[0038] The utility model arranges support plates 42 on both sides of the cigarette pack conveying channel, and the first end of the support plate 42 is arranged on the packaging machine frame, the second end of the support plate 42 is connected to the fixed plate 41, and the first end of the fixed rod 43 is connected to the support plate 42, and the two ends of the spring 44 are respectively connected to the second end of the fixed rod 43, so that the soldering iron 3 can move stably and the production cost is effectively reduced.

[0039] In one embodiment of the cigarette pack transparent paper end heat sealing device of the present invention, the control component 4 also includes a rotating shaft 45 and a connecting plate 46, the first end of the connecting plate 46 is connected to the rotating shaft 45, the second end of the connecting plate 46 is connected to the fixed plate 41, and the rotating shaft 45 is rotatably connected to the packaging machine frame.

[0040] The utility model connects the first end of the connecting plate 46 to the rotating shaft 45 and the second end of the connecting plate 46 to the fixed plate 41, and the rotating shaft 45 is rotatably connected to the packaging machine frame, so that the soldering iron 3 can provide support to the soldering iron 3 and the fixed plate 41 through the rotating shaft 45 and the connecting plate 46 during the movement.

[0041] In one embodiment of the heat-sealing device for the transparent paper end of a cigarette pack of the present invention, a plurality of through holes (not shown in the figure) are provided on the fixing plate 41, and a plurality of connecting holes (not shown in the figure) are provided on the soldering iron 3. Fastening bolts 47 are installed on the through holes and the connecting holes to connect the fixing plate 41 to the soldering iron 3. This arrangement ensures the stability of the soldering iron 3 fixed to the fixing plate 41.

[0042] In one embodiment of the cigarette pack transparent paper end heat sealing device of the present invention, the cigarette pack conveying assembly 2 includes a lifting plate 21 and a push plate 22, the lifting plate 21 and the push plate 22 are located at the first end of the fixed base 1, and the push plate 22 is arranged opposite to the cigarette pack conveying channel. The lifting plate 21 is used to convey the cigarette pack to the inlet end of the cigarette pack conveying channel, and the push plate 22 is used to push the cigarette pack into the cigarette pack conveying channel.

[0043] The utility model positions the lifting plate 21 and the pushing plate 22 at the first end of the fixed base 1, and arranges the pushing plate 22 relative to the cigarette pack conveying channel, thereby conveying the cigarette pack to the inlet end of the cigarette pack conveying channel through the lifting plate 21, and then pushing the cigarette pack into the cigarette pack conveying channel through the pushing plate 22, thereby effectively increasing the automation of the cigarette pack transparent paper end heat sealing device of the utility model and reducing the labor intensity of the operator.
