[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 packaging for small cigarette packs.

[0003] During the production process, common problems such as dense air bubbles at the sealing folds and overlaps of cigarette packs, air leakage, loose and non-compact cigarette packs, weak adhesion, and radial shrinkage lines caused by high temperatures are prone to occur on the outer transparent paper of cigarette packs. In order to achieve a smooth and wrinkle-free appearance of cigarette packs, it is necessary to install a cigarette pack outer transparent paper shaping device.

[0004] The existing shaping device consists of two heating plates, one above the other.

[0030] A movable, reshapeable box structure, such as Figure 1 As shown, it includes an outer housing 1, an inner housing 2, a drive bracket 3, a housing moving mechanism 32, and a clearance adjustment mechanism 5.

[0031] The outer casing 1 has a feed inlet 11 on the front side and a discharge outlet 12 on the rear side. The cigarette pack enters the shaping box structure of this embodiment through the feed inlet 11, and after being heated and shaped, it leaves the shaping box structure of this embodiment through the discharge outlet 12.

[0032] The bottom of the outer casing 1 is provided with a left-right extending slide rail 13, and the inner casing 2 is slidably mounted on the slide rail 13, so that the inner casing 2 can be slidably set inside the outer casing 1.

[0033] The drive bracket 3 is located on the left side of the outer casing 1. In this embodiment, the casing moving mechanism 32 includes a cylinder 41, which is mounted on the drive bracket 3. The piston rod of the cylinder 41 is connected to the left side of the inner casing 2 through the connecting bracket 42, and the inner casing 2 is driven to move left and right by the telescopic cylinder 41.

[0034] The inner box 2 is provided with an upper shaping component 21, a lower shaping component 22 and an intermediate shaping mechanism, which are used to heat and shape the tobacco pack that has passed through the shaping box structure of this embodiment.

[0035] The upper shaping assembly 21 is slidably installed inside the inner housing 2. The upper shaping assembly 21 includes an upper heating plate 211 and an upper heat insulation plate 212 disposed at the bottom.

[0036] The lower shaping assembly 22 is slidably installed inside the inner housing 2. The lower shaping assembly 22 includes a lower heating plate 221 and a lower heat insulation plate 222 disposed at the top.

[0037] A heating channel 24 is provided between the upper heating plate 211 and the lower heating plate 221, and a heat insulation channel 25 is provided between the upper heat insulation plate 212 and the lower heat insulation plate 222. When the box moving mechanism 32 drives the inner box 2 to move left and right, the heating channel 24 and the heat insulation channel 25 connect the feed inlet 11 and the discharge outlet 12.

[0038] In this embodiment, when the shaping box structure is in working condition, the cylinder 41 pulls the inner box 2 to the left, so that the heating channel 24 connects the feed inlet 11 and the discharge outlet 12. At this time, the tobacco pack passes through the heating channel 24, and the tobacco pack contacts the upper heating plate 211 and the lower heating plate 221, thereby heating and shaping the tobacco pack.

[0039] When the shaping box structure is in the shutdown condition, cylinder 41 pushes the inner box 2 to the right, so that the heat insulation channel 25 connects the feed inlet 11 and the discharge outlet 12. At this time, the tobacco pack is located in the heat insulation channel 25, and the tobacco pack contacts the upper heat insulation plate 212 and the lower heat insulation plate 222 to prevent the tobacco pack from being overheated and damaged.

[0040] In addition, the intermediate shaping component 23 is disposed between the upper shaping component 21 and the lower shaping component 22. The intermediate shaping component 23 includes an intermediate heating plate 231 and an intermediate heat-insulating plate. The intermediate heating plate 231 divides the heating channel 24 into upper and lower layers, and the intermediate heat-insulating plate divides the heat-insulating channel 25 into upper and lower layers, so that this embodiment can heat and shape the upper and lower layers of tobacco packs simultaneously, thereby improving the shaping efficiency of this embodiment.

[0041] The yielding adjustment mechanism 5 in this embodiment includes a drive component 51, an upper transmission component 54, a synchronization component 53, and a lower transmission component 52, which can synchronously control the relative movement of the upper shaping component 21 and the lower shaping component 22.

[0042] Specifically, the upper transmission assembly 54 includes an upper rotating shaft 541 whose two ends are rotatably connected to the inner housing 2, and an upper swing rod 542 extending to the left is provided on the upper rotating shaft 541. The upper swing rod 542 is matched with the bottom of the upper shaping assembly 21.

[0043] The lower transmission assembly 52 includes a lower rotating shaft 521 whose two ends are rotatably connected to the inner housing 2, and a lower swing rod 522 extending to the left is provided on the lower rotating shaft 521. The lower swing rod 522 is matched with the bottom of the lower shaping assembly 22.

[0044] The synchronization assembly 53 includes a synchronization arm 531, the middle of which is rotatably connected to one side of the outer housing 1. The upper transmission assembly 54 and the lower transmission assembly 52 are symmetrically arranged on the upper and lower sides of the synchronization arm 531. An upper swing arm 543 extending toward the synchronization arm 531 is provided on the upper rotating shaft 541, and one end of the synchronization arm 531 is connected to the upper swing arm 543 via an upper connecting rod 533. A lower swing arm 523 extending toward the synchronization arm 531 is provided on the lower rotating shaft 521, and the other end of the synchronization arm 531 is connected to the lower swing arm 523 via a lower connecting rod 532.

[0045] The drive assembly 51 includes a rotation output device 511 and a cam swing arm 513. The rotation output device 511 is mounted on the drive bracket 3, and a drive cam 512 is provided on the output shaft of the rotation output device 511. A support plate 31 is provided on the top of the drive bracket 3, and the middle part of the cam swing arm 513 is rotatably mounted on the support plate 31. One end of the cam swing arm 513 extends to the right and mates with the top of the side wall of the drive cam 512. In this embodiment, a transmission swing arm 524 is provided at one end of the lower rotating shaft 521, and the other end of the cam swing arm 513 extends downward and is connected to the transmission swing arm 524 through a transmission connecting rod 514.

[0046] When the overall housing structure of this embodiment is in working condition, the protruding part of the side wall of the drive cam 512 pushes one end of the cam rocker arm 513 upward. The other end of the cam rocker arm 513 drives the lower rotating shaft 521 to rotate through the transmission connecting rod 514 and the transmission rocker arm 524, thereby causing the lower rocker arm 522 to rotate upward and push the lower shaping assembly 22 to move upward. At the same time, the lower rotating shaft 521 pushes the upper rotating shaft 541 to rotate through the lower rocker arm 523, the lower connecting rod 532, the synchronizing arm 531, the upper connecting rod 533, and the upper rocker arm 543, thereby causing the upper rocker arm 542 to rotate downward and push the upper shaping assembly 21 to move downward. The upper shaping assembly 21 and the lower shaping assembly 22 press the tobacco pack together to perform heating and shaping.

[0047] When the cigarette pack needs to be moved after shaping, the non-protruding part of the drive cam 512 contacts one end of the cam rocker arm 513. Similarly, the lower rocker arm 522 rotates downward to release the lower shaping component 22, and simultaneously the upper rocker arm 542 rotates upward to release the upper shaping component 21. The upper shaping component 21 and the lower shaping component 22 release the cigarette pack, preventing it from being compressed and damaged during movement.

[0048] 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.
