[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0036] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] like Figures 1 to 7 As shown, an embodiment of the present invention provides an automatic seal sticking device for a cigarette pack packaging machine, comprising: a box body 1, a cigarette pack conveying component 2, a gluing component, a seal pushing component 5, and a cigarette pack storage channel 7 and a cigarette pack storage component 6 arranged on the box body 1.

[0039] The cigarette pack storage channel 7 is located above and connected to the cigarette pack conveyor assembly 2. The cigarette pack conveyor assembly 2 is located on one side of the cigarette pack storage assembly 6 and is used to transport sealed cigarette packs into the cigarette pack storage assembly 6. The seal pushing assembly 5 is used to push the seals onto the gluing assembly, where they are then glued and affixed to the cigarette packs. The cigarette pack conveyor assembly 2 is used to push the sealed cigarette packs into the cigarette pack storage assembly 6.

[0040] The gluing component includes a glue cylinder 31 part 3 and a seal adsorption part 4. The seal adsorption part 4 includes a first fixed bracket 41, a cross-shaped rotating plate 42 and a suction device 43. The first fixed bracket 41 is connected to the box body 1. The glue cylinder 31 part 3 and the suction device 43 are respectively fixed at both ends of the first fixed bracket 41. The cross-shaped rotating plate 42 can be rotatably set on the first fixed bracket 41. The first end of the cross-shaped rotating plate 42 is located between the cigarette pack conveying component 2 and the cigarette pack storage component 6. The second end of the cross-shaped rotating plate 42 is located between the suction device 43 and the seal pushing component 5, and a suction hole 45 connected to the suction device 43 is provided on the outer edge of the cross-shaped rotating plate 42; the glue cylinder 31 part 3 is used to apply glue to the seal.

[0041] When it is necessary to re-stick the seal on the cigarette pack, the operator starts the seal adsorption part 4, so that the cross-shaped rotating plate 42 adsorbs the seal in the seal pushing component 5 through the suction device 43, and glues the seal through the glue cylinder 31 part 3. Then the cross-shaped rotating plate 42 rotates, and moves the seal between the cigarette pack conveying component 2 and the cigarette pack storage component 6. The cigarette pack in the cigarette pack storage channel 7 is pushed into the cigarette pack storage component 6 through the cigarette pack conveying component 2, so that the seal is stuck to the cigarette pack.

[0042] The present invention arranges the cigarette pack storage channel 7 above the cigarette pack conveying assembly 2 and communicates with the cigarette pack conveying assembly 2, and the cigarette pack conveying assembly 2 is located on one side of the cigarette pack storage assembly 6; and connects the first fixed bracket 41 to the box body 1, and the glue cylinder 31 part 3 and the suction device 43 are respectively fixed at both ends of the first fixed bracket 41, and the cross-shaped rotating plate 42 is rotatably set on the first fixed bracket 41, and the first end of the cross-shaped rotating plate 42 is located between the cigarette pack conveying assembly 2 and the cigarette pack storage assembly 6, and the second end of the cross-shaped rotating plate 42 is located between the suction device 43 and the seal pushing assembly 5, and the outer edge of the cross-shaped rotating plate 42 is provided with a suction hole 45 connected with the suction device 43. When it is necessary to re-stick the seal on the cigarette pack, the operator starts the seal adsorption part 4, so that the cross-shaped rotating plate 42 adsorbs the seal in the seal pushing component 5 through the suction device 43, and glues the seal through the glue cylinder 31 part 3. Then the cross-shaped rotating plate 42 rotates, and the seal is moved between the cigarette pack conveying component 2 and the cigarette pack storage component 6. The cigarette pack in the cigarette pack storage channel 7 is pushed into the cigarette pack storage component 6 through the cigarette pack conveying component 2, and the seal is stuck to the cigarette pack, avoiding the problem of manual sealing causing the seal to be not firmly stuck or crookedly stuck, thereby reducing the labor intensity of the operator and improving work efficiency.

[0043] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 5 As shown, four mutually perpendicular connecting plates 44 are provided around the cross-shaped rotating plate 42 to form a cross-shaped structure, and the air suction holes 45 pass through the cross-shaped rotating plate 42 and the connecting plates 44 respectively.

[0044] Specifically, one of the connecting plates 44 is located between the cigarette pack conveying assembly 2 and the cigarette pack storage assembly 6, another connecting plate 44 is located between the suction device 43 and the seal pushing assembly 5, and another connecting plate 44 is located between the first fixed bracket 41 and the glue cylinder 31 part 3.

[0045] The cigarette pack conveying assembly 2 and the seal pushing assembly 5 are located on either side of a cross-shaped rotating plate 42, with the glue cylinder 31 portion 3 positioned between them. During operation, the seal pushing assembly 5 first pushes the seal onto the connecting plate 44. A connecting plate 44 of the cross-shaped rotating plate 42 then attracts the seal via the air suction device 43. The cross-shaped rotating plate 42 is then rotated, causing the connecting plate 44 with the attracted seal to align with the glue cylinder 31 portion 3, where glue is applied to the seal. The cross-shaped rotating plate 42 is then rotated again, causing the connecting plate 44 with the attracted seal to rotate between the cigarette pack conveying assembly 2 and the cigarette pack storage assembly 6. At this point, the cigarette pack conveying assembly 2 pushes the cigarette pack to the cigarette pack storage assembly 6, allowing the seal to be attached to the cigarette pack, thereby completing the resealing of the cigarette pack and effectively improving work efficiency.

[0046] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 2 As shown, the automatic sealing device of the cigarette pack packaging machine also includes a Z-shaped fixing frame 11, the first end of the Z-shaped fixing frame 11 is connected to the box body 1, and a first connecting bracket 12 is also provided on the Z-shaped fixing frame 11, and the first connecting bracket is connected to the sealing pushing component 5.

[0047] Specifically, at least part of the glue cylinder 31 is also arranged on the Z-shaped fixing frame 11 .

[0048] The present invention connects the first end of the Z-shaped fixing frame 11 to the box body 1, and further provides a first connecting bracket 12 on the Z-shaped fixing frame 11, and the first connecting bracket is connected to the seal pushing assembly 5, thereby increasing the stability of the seal pushing assembly 5 installed on the box body 1.

[0049] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 5 As shown, a second connecting bracket is also provided on the Z-shaped fixing frame 11.

[0050] The glue cylinder 31 part 3 includes a glue cylinder 31, a glue lifting plate 32, a first air cylinder 33, a connecting block 34, a second drive motor 35 and a glue coating plate 36. The glue cylinder 31 is fixed to the bottom of the first fixed bracket 41, the glue lifting plate 32 is at least partially inserted into the glue cylinder 31, the first air cylinder 33 is located above the glue cylinder 31, the first cylinder 33 is connected to the connecting block 34, and the connecting block 34 is connected to the glue lifting plate 32.

[0051] The second drive motor 35 is disposed at the bottom of the second end of the Z-shaped fixing frame 11 . The output end of the second drive motor 35 is connected to the glue coating plate 36 . The glue supply plate 32 is located between the connecting plate 44 and the glue coating plate 36 .

[0052] Specifically, the glue lifting plate 32 has an opening, the width and length of the opening are greater than the width and length of the glue coating plate 36, so that the glue coating plate 36 can move through the opening to contact the connecting plate 44, thereby gluing the seal on the connecting plate 44.

[0053] The first air cylinder 33 is used to drive the glue lifting plate 32 to move in the glue cylinder 31 so that the glue is covered on the glue lifting plate 32 .

[0054] When the seal on the connecting plate 44 needs to be glued, the first cylinder 33 is first activated, driving the connecting block 34 upward. This movement of the connecting block 34 drives the glue-lifting plate 32 upward, thereby pulling the glue-lifting plate 32 out of the glue cylinder 31. Next, the second drive motor 35 is activated, driving the glue-applying plate 36 toward the glue-applying plate 32 until it contacts the glue-applying plate 32, thereby applying glue to the glue-applying plate 36. Next, the first cylinder 33 drives the connecting block 34 downward, which in turn drives the glue-applying plate 32 downward, thereby partially inserting the glue-applying plate 32 into the glue cylinder 31. At this point, the opening in the glue-applying plate 32 aligns with the glue-applying plate 36. The second cylinder then drives the glue-applying plate 36 toward the connecting plate 44, bringing it into contact with the seal, thereby applying glue to the seal. This further enhances the intelligence of the automatic seal-applying device of the cigarette pack packaging machine of the present invention.

[0055] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 5 As shown, the seal adsorption portion 4 further includes a first drive motor 46 , which is fixed to the first fixing bracket 41 , and an output shaft of the first drive motor 46 passes through the first fixing bracket 41 and is connected to the cross-shaped rotating plate 42 .

[0056] The present invention fixes the first drive motor 46 on the first fixed bracket 41, and the output shaft of the first drive motor 46 passes through the first fixed bracket 41 and is connected to the cross-shaped rotating plate 42, so that the first drive motor 46 drives the cross-shaped rotating plate 42 to rotate, thereby further improving work efficiency.

[0057] In one embodiment of the automatic seal sticking device of the cigarette pack packaging machine of the present invention, the gluing component also includes a first detection switch 8 and a second detection switch 9. The first detection switch 8 and the second detection switch 9 are respectively arranged on the two ends of the first fixed bracket 41, and respectively correspond to the upper and lower ends of the cross-shaped rotating plate 42. The first detection switch 8 is used to detect whether the cross-shaped rotating plate 42 has moved to a preset position, and the second detection switch 9 is used to detect whether the seal is adsorbed on the cross-shaped rotating plate 42.

[0058] Specifically, the first detection switch 8 is disposed on top of the first fixed bracket 41. When the first detection switch 8 detects that the cross-shaped rotating plate 42 has moved to a preset position, it controls the seal pushing assembly 5 to operate, causing the seal pushing assembly 5 to push the seal onto the connecting plate 44. The preset position refers to a connection plate 44 on the cross-shaped rotating plate 42 corresponding to the first detection switch 8. At this time, the other three connection plates 44 on the cross-shaped rotating plate 42 are respectively located between the cigarette pack conveying assembly 2 and the cigarette pack storage assembly 6, between the air suction device 43 and the seal pushing assembly 5, and between the first fixed bracket 41 and the glue cylinder 31 portion 3.

[0059] A second detection switch 9 is mounted at the bottom of the first fixed bracket 41 and corresponds to the gluing plate 36, thereby detecting whether the seal is attached to the connecting plate 44 of the cross-shaped rotating plate 42. When the second detection switch detects that the seal is attached to the connecting plate 44 of the cross-shaped rotating plate 42, the first cylinder 33 and the second cylinder are controlled to begin operation. When the second detection switch 9 detects that the seal is not attached to the connecting plate 44 of the cross-shaped rotating plate 42, the gluing process is skipped, and the first drive motor 46 drives the cross-shaped rotating plate 42 to rotate 90 degrees counterclockwise, restarting the seal attachment process.

[0060] The present invention realizes automatic seal sticking by arranging the first detection switch 8 and the second detection switch 9 on the two ends of the first fixed bracket 41, and corresponding to the upper and lower ends of the cross-shaped rotating plate 42 respectively, and controls the adsorption of the seal and the gluing of the seal through the first detection switch 8 and the second detection switch 9, thereby reducing the production of defective products.

[0061] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 5 As shown, the seal pushing assembly 5 includes a third cylinder 51, a seal storage 52 and a first pushing plate 53. The seal storage 52 is fixed on the first connecting bracket 12, and the output end of the third cylinder 51 is connected to the first pushing plate 53. A plurality of seals are placed inside the seal storage 52, and the first pushing plate 53 is located inside the seal storage 52 and abuts against the seals.

[0062] Specifically, when the first detection switch 8 detects that the cross-shaped rotating plate 42 has moved to the preset position, the third cylinder 51 is controlled to start, and the third cylinder 51 drives the first pushing plate 53 to move toward the connecting plate 44, thereby pushing the seal in the seal library 52 to the connecting plate 44, and under the action of the suction device 43, the seal is adsorbed on the connecting plate 44.

[0063] The present invention fixes the seal library 52 on the first connecting bracket 12, and the output end of the third cylinder 51 is connected to the first pushing plate 53. The first pushing plate 53 is located inside the seal library 52 and abuts against the seal, thereby enabling the seal to be moved smoothly and quickly to the connecting plate 44.

[0064] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 7 As shown, the cigarette pack conveying assembly 2 includes a support plate 21, a first baffle 22, a fourth cylinder 23, a third detection switch 24, a fourth detection switch 25 and a fifth cylinder 26; the support plate 21 is fixed on the side wall of the box body 1, the cigarette pack storage channel 7 is located above the support plate 21, the fourth cylinder 23 is arranged on the support plate 21, and the output end of the fourth cylinder 23 is connected to the second pushing plate, and the second pushing plate is used to convey the cigarette packs in the cigarette pack storage channel 7 to the cigarette pack storage assembly 6; the fifth cylinder 26 is located below the support plate 21, and the output end of the fifth cylinder 26 is connected to the first baffle 22, and the first baffle 22 is located between the support plate 21 and the cigarette pack storage assembly 6.

[0065] The third detection switch 24 and the fourth detection switch 25 are both arranged on the side wall of the cigarette pack storage channel 7. The third detection switch 24 is used to detect whether the cigarette pack has fallen onto the support plate 21. The fourth detection switch 25 is located between the first baffle 22 and the support plate 21. The fourth detection switch 25 is used to detect whether there is a seal on the cross-shaped rotating plate 42.

[0066] Specifically, when the third detection switch 24 detects that a cigarette pack has fallen onto the support plate 21 and the fourth detection switch 25 detects that a seal has been applied to the cross-shaped rotating plate 42, the fifth cylinder 26 is activated, driving the first baffle 22 downward, causing it to move away from the end of the support plate 21, thereby establishing electrical connection between the support plate 21 and the cigarette pack storage assembly 6. The fourth cylinder 23 is then activated, driving the second push plate toward the cigarette pack storage assembly 6, thereby pushing the cigarette pack into the cigarette pack storage assembly 6. During this process, the seal is affixed to the cigarette pack, completing the re-seal of the cigarette pack and further improving work efficiency.

[0067] When the third detection switch 24 does not detect the cigarette pack falling onto the support plate 21, the fourth detection switch 25 does not detect the seal on the cross-shaped rotating plate 42, or the third detection switch 24 does not detect the cigarette pack falling onto the support plate 21 and the fourth detection switch 25 does not detect the seal on the cross-shaped rotating plate 42, the fourth cylinder 23 and the fifth cylinder 26 do not work.

[0068] In addition, the cigarette pack conveying assembly 2 further includes a seventh cylinder 27, a second fixed bracket 28, and a pressure plate 29, all of which are located above the support plate 21. The second fixed bracket 28 is mounted on the side wall of the cigarette pack storage channel 7, and the seventh cylinder 27 is fixed to the second fixed bracket 28. The output end of the seventh cylinder 27 is connected to the pressure plate 29, which abuts against the side wall of the cigarette packs within the cigarette pack storage channel 7.

[0069] When the third detection switch 24 detects that the cigarette pack has fallen onto the support plate 21, the seventh cylinder 27 is controlled to start, and the seventh cylinder 27 drives the pressing plate 29 to move toward the cigarette pack, and gently pushes the cigarette pack inside the cigarette pack storage channel 7, and then returns, thereby sorting the cigarette packs.

[0070] Furthermore, after the seventh cylinder 27 completes its action, the cigarette pack storage assembly 6 rotates one station clockwise.

[0071] In one embodiment of the automatic sealing device for cigarette packaging machine of the present invention, Figures 1 to 7 As shown, the cigarette pack storage assembly 6 includes a drying wheel 61, a sixth cylinder, a cigarette pack detection sensor 62, a second baffle 63 and a cigarette pack conveying channel 64. The drying wheel 61 is rotatably set on the box body 1. The drying wheel 61 has multiple cigarette pack storage cavities 65. The cigarette pack detection sensor 62 is located inside the drying wheel 61 and directly above the cigarette pack conveying channel 64. The cigarette pack detection sensor 62 is used to detect whether there is a cigarette pack in the cigarette pack storage cavity 65.

[0072] The second baffle 63 is located above the cigarette pack conveying channel 64 and on both sides of the cigarette pack conveying channel 64. The output end of the sixth cylinder has a third pushing plate, which is used to push the cigarette packs in the cigarette pack storage chamber 65 into the cigarette pack conveying channel 64.

[0073] Specifically, the drying wheel 61 rotates at intervals to ensure that the sixth cylinder pushes the cigarette packs in the cigarette pack storage chamber 65 into the cigarette pack delivery channel 64, while the fourth cylinder 23 drives the second pushing plate to push the cigarette packs into the cigarette pack storage chamber 65. It should be noted that the intervals for the rotation of the drying wheel 61 are not limited here and can be determined according to actual conditions.

[0074] When the cigarette pack detection sensor 62 detects that there is a cigarette pack in the cigarette pack storage chamber 65, the sixth cylinder is controlled to start, and the sixth cylinder drives the third pushing plate to move, so that the third pushing plate pushes the cigarette pack in the cigarette pack storage chamber 65 to the cigarette pack conveying channel 64. At the same time, due to the limiting effect of the second baffle 63 on the cigarette pack, the problem of the cigarette pack falling to the outside and causing damage to the cigarette pack is avoided.

[0075] In addition, the interior of the drying wheel 61 has a through hole 68 connected to the cigarette pack storage cavity 65. The cigarette pack storage assembly 6 also includes a support rod 69. The first end of the support rod 69 is connected to the second baffle 63, and the second end of the support rod 69 extends above the through hole 68.
