[0002] In modern cigarette production, companies have increasingly higher requirements for product quality, including stricter requirements for the airtightness and flatness of the transparent paper sealing of cigarette packs. Common problems encountered during the production process include dense air bubbles at the sealing folds and overlaps, air leakage, loose and uncompacted packs, weak adhesion, and radial shrinkage lines caused by high temperatures. To achieve a smooth and wrinkle-free appearance, the cigarette packs need to be shaped using a shaping device.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0032] A tobacco pack top and bottom shaping mechanism includes a running channel 1, a diversion mechanism 2, a first working condition adjustment mechanism 4, a second working condition adjustment mechanism 5, a clearance adjustment mechanism 6, and two tightening heating mechanisms 3. The running channel 1 is used to transport the tobacco pack from back to front.

[0033] In this embodiment, the running channel 1 includes upper and lower layers, and the diversion mechanism 2 is located at the rear of the running channel 1. The diversion mechanism 2 is used to send the upper and lower tobacco packs to the upper and lower layers of the running channel 1 respectively. By setting up a double-layered running channel 1 and setting up the diversion mechanism 2 to send the upper and lower tobacco packs to the upper and lower layers of the running channel 1 respectively, this embodiment can simultaneously perform top and bottom shaping of the two tobacco packs, thus improving shaping efficiency.

[0034] Specifically, the diversion mechanism 2 includes two pressure plates 21 set on the left and right sides of the running channel 1. Each pressure plate 21 is provided with two upper and lower smoke-dividing guide wheels 22 on the side of the pressure plate 21 closest to the running channel 1. The front side of the upper smoke-dividing guide wheel 22 is inclined upward, and the front side of the lower smoke-dividing guide wheel 22 is inclined downward.

[0035] In addition, each of the cigarette-distributing guide wheels 22 is connected to the pressure plate 21 via a swing rod 23, with one end of the swing rod 23 connected to the cigarette-distributing guide wheel 22 tilted forward. A limit block 24 is provided on the rear side of each swing rod 23, and the limit block 24 is fixed to the pressure plate 21. The limit block 24 is held against the swing rod 23 by a limit spring 25. For cigarette packs of different sizes, the limit block 24 can press the cigarette-distributing guide wheel 22 firmly against the left and right sides of the cigarette pack via the limit spring 25, thereby enabling the distribution of cigarettes of different sizes.

[0036] Two pressing and heating mechanisms 3 are respectively arranged on the left and right sides of the running channel 1, used to press the top and bottom of the tobacco pack from the left and right sides and heat and shape it. In this embodiment, the pressing and heating mechanism 3 includes a connecting block 5231, a guide bar 33, and two pressing and heating plates 32. The two pressing and heating plates 32 are respectively arranged at the upper and lower ends of the side of the connecting block 5231 near the running channel 1, and the two pressing and heating plates 32 are respectively matched with the upper and lower layers of the running channel 1. The guide bar 33 is arranged on the side of the connecting block 5231 near the running channel 1, and the guide bar 33 is arranged between the two pressing and heating plates 32, used to guide the upper and lower layers of tobacco pack.

[0037] The first working condition adjustment mechanism 4 and the yielding adjustment mechanism 6 are located on the left side of the operating channel 1 and are used to control the left side clamping heating mechanism 3.

[0038] Specifically, a first fixed bracket 34 is provided on the left side of the operating channel 1, and a first sliding support 35 is provided on the left side of the first fixed bracket 34. The first sliding support 35 is connected to the clamping heating mechanism 3 on the left side of the operating channel 1 through a first limiting rod 36. The first limiting rod 36 can slide axially through the first fixed bracket 34. A baffle 37 is connected to the first sliding support 35, and the baffle 37 is connected to the first fixed bracket 34 through a return spring 38.

[0039] The first working condition adjustment mechanism 4 includes a first cylinder 41, which is mounted on a first fixed bracket 34. The piston rod of the first cylinder 41 extends to the left, and a push block 42 that matches the baffle 37 is provided on the piston rod of the first cylinder 41.

[0040] The clearance adjustment mechanism 6 includes a fixed support 61. A rotary drive device 62 and a top and bottom bracket 63 are mounted on the top of the fixed support 61. A cam 64 and a rocker arm 65 are rotatably mounted on the top and bottom bracket 63. The output shaft of the rotary drive device 62 is coaxially connected to the cam 64. The middle part of the rocker arm 65 is rotatably connected to the top and bottom bracket 63. The other end of the rocker arm 65 extends downward and mates with the right side of the cam 64. One end of the rocker arm 65 extends upward and is rotatably connected to the first sliding support 35.

[0041] The second operating condition adjustment mechanism 5 is located on the right side of the operating channel 1 and is used to control the right-side clamping heating mechanism 3.

[0042] Specifically, a second fixed bracket 34' is provided on the right side of the operating channel 1. Another clamping heating mechanism 3 is connected to a second sliding support 35', and the second sliding support 35' is connected to a second limiting rod 36', which is slidably mounted on the second fixed bracket 34'.

[0043] The second working condition adjustment mechanism 5 includes a second cylinder 51, which is mounted on the second fixed bracket 34'. The piston rod of the second cylinder 51 extends toward the running channel 1, and a connecting block 5231 connected to the pressing heating mechanism 3 is provided on the piston rod of the second cylinder 51.

[0044] In this embodiment, the top and bottom shaping mechanism is controlled to switch between standby and running conditions through the first working condition adjustment mechanism 4 and the second working condition adjustment mechanism 5.

[0045] Specifically, upon receiving a shutdown / standby signal, the first cylinder 41 extends and pushes the baffle 37 to the left, causing the left-side tightening heating mechanism 3 to move to the left, away from the top and bottom surfaces of the left side of the tobacco pack. At this time, the lower end of the swing arm 65 rotates to the right, preventing the positioning adjustment mechanism 6 from controlling the tightening heating mechanism 3. Additionally, the second cylinder 51 retracts, and the right-side tightening heating mechanism 3 moves to the right, away from the top and bottom surfaces of the right side of the tobacco pack. In this embodiment, the top and bottom shaping mechanism enters the shutdown / standby state.

[0046] When the start-up signal is received, the first cylinder 41 retracts, and the return spring 38 pulls the baffle 37 to the right, causing the left-side pressing heating mechanism 3 to move to the right and press the top and bottom surfaces of the left side of the tobacco pack. Simultaneously, the second cylinder 51 extends and pushes the second pressing heating mechanism 3 to the left, causing the right-side pressing heating mechanism 3 to move to the left and press the top and bottom surfaces of the right side of the tobacco pack. The top and bottom shaping mechanism of this embodiment then enters the operating state.

[0047] In addition, during operation, the retraction adjustment mechanism 6 controls the tightening heating mechanism 3 to retract and release the tobacco pack. Specifically, when the tobacco pack needs to move forward, the rotary drive device 62 drives the cam 64 to rotate. The protrusion of the cam 64 pushes the lower end of the swing arm 65 to the right, causing the swing arm 65 to rotate and pull the left-side tightening heating mechanism 3 to move to the left. The tightening heating mechanism 3 retracts and releases the tobacco pack, preventing the top and bottom surfaces from being squeezed and resulting in large-area scratches and compression marks when the tobacco pack moves.

[0048] This invention uses two pressing heating mechanisms 3 to heat and shape the tobacco pack from both sides, thus overcoming the deficiency of existing tobacco pack shaping devices that cannot heat and shape the top and bottom of the tobacco pack. Furthermore, in this embodiment, the first working condition adjustment mechanism 4 and the clearance adjustment mechanism 6 operate independently without interference.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
