[0018] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0020] It will be understood that spatial relational terms such as "under," "beneath," "beneath," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be understood that in addition to the orientations shown in the figures, spatial relational terms also include different orientations of the device in use and operation.

In addition, the device may also include alternative orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0021] A six-sided airtight shaping device for cigarette packets, comprising a parallel turret mechanism 1, a side sealing shaping mechanism 2, a sub-packaging mechanism 3, a top and bottom shaping mechanism 4, a large surface shaping mechanism 5 and a connecting box 6. Figure 1 As shown, the cigarette packs move along the cigarette pack conveying channel extending forward and backward, and the parallel turret mechanism 1, the side sealing and shaping mechanism 2, the sub-packaging mechanism 3, the top and bottom shaping mechanism 4 and the large surface shaping mechanism 5 are arranged in sequence along the cigarette pack conveying channel.

[0022] The parallel turret mechanism 1 includes a parallel turret turntable 11 and multiple parallel turret molds 12. The parallel turret turntable 11 can rotate along a horizontal axis. The parallel turret molds 12 are evenly arranged around the circumference of the parallel turret turntable 11. A parallel turret mold channel 13 that matches the cigarette packs is formed between each two adjacent parallel turret molds 12. A cigarette pusher assembly 14 is also installed on the top of the parallel turret mechanism 1. This pusher assembly 14 is used to push cigarette packs toward the conveying station of the circular conveyor assembly 21, allowing the cigarette packs to enter the subsequent mechanism in groups for heating and shaping.

[0023] In this embodiment, each parallel turret box mold channel 13 can accommodate two upper and lower cigarette packs, and the upper and lower cigarette packs are delivered to the conveying station of the circulating conveying component 21 each time.

[0024] The side seal shaping mechanism 2 also includes a circulating conveying assembly 21 and a side seal shaping assembly 22. The circulating conveying assembly 21 includes a vertical turret turntable 211 and a plurality of vertical turret molds 212. The vertical turret turntable 211 can rotate along a horizontal axis. The vertical turret molds 212 are evenly arranged around the circumference of the vertical turret turntable 211. A vertical turret mold channel 213 that matches the cigarette pack is formed between every two adjacent vertical turret molds 212.

[0025] A conveying station and two shaping stations are arranged around the vertical turret turntable 211. The conveying station is located at the top of the vertical turret turntable 211. Both the conveying station and the shaping station are matched with the vertical turret box mold channel 213. The circular conveying assembly 21 is used to allow cigarette packs from the conveying station to pass through the two shaping stations in sequence and then return to the conveying station.

[0026] The side sealing shaping assembly 22 includes two push plates 221 and four side sealing heating plates 222 . Side sealing heating plates 222 are symmetrically arranged on the front and rear sides of each shaping station, and the two side sealing heating plates 222 on the same side are each connected by a push plate 221 .

[0027] The side seal heating plate 222 is used to heat and shape the front and rear side covers of the cigarette packs within the shaping station. This embodiment has two shaping stations, and each cigarette pack undergoes two shaping operations. Furthermore, the provision of the circulating conveyor assembly 21 allows the side seal shaping assembly 22 to avoid the cigarette pack conveyor channel, ensuring smooth movement of the cigarette packs along the channel.

[0028] The packing mechanism 3 includes two fixed bases 31, symmetrically arranged on either side of a horizontal plane perpendicular to the cigarette pack conveying channel. Upper and lower cigarette sorting guide wheels 32 are installed on each side of the fixed bases 31, near the cigarette pack conveying channel. The upper cigarette sorting guide wheel 32 is tilted upward near the top and bottom shaping mechanism 4, while the lower cigarette sorting guide wheel 32 is tilted downward near the top and bottom shaping mechanism 4. These wheels are used to separate the cigarette packs into two layers, with one of the two cigarette packs in each group entering the upper layer and the other entering the lower layer.

[0029] The top and bottom shaping mechanism 4 includes top and bottom heating plates 41, which are symmetrically arranged on the left and right sides of the cigarette packet conveying channel, and are used to heat and shape the top and bottom surfaces of the cigarette packets.

[0030] The large-surface shaping mechanism 5 includes a large-surface heating plate 51 and an intermediate heating plate 52. The large-surface heating plates 51 are symmetrically arranged on the upper and lower sides of the cigarette pack conveying channel. In this embodiment, two large-surface heating plates 51 are respectively installed on the upper and lower sides of the cigarette pack conveying channel. The two large-surface heating plates 51 on the same side are arranged in a front-to-back sequence, thereby heating and shaping the upper and lower large surfaces of the cigarette packs.

[0031] The middle heating plate 52 is arranged between the two large-surface heating plates 51. The two cigarette packs in the same group pass through the upper and lower sides of the middle heating plate 52 respectively, so that the two large surfaces of the upper and lower cigarette packs are heated and shaped at the same time.

[0032] This embodiment improves the airtightness of the cigarette package by providing a side sealing shaping mechanism 2, a top and bottom shaping mechanism 4, and a large surface shaping mechanism 5 to heat and shape the six sides of the cigarette package. Furthermore, this embodiment shapes the six sides of both the upper and lower cigarette packages in each round, improving shaping efficiency.

[0033] In addition, a reversing gear set 7 and a gear box 8 are provided on the top of the connecting box body 6 .

[0034] Among them, the reversing gear set 7 includes two output ends, one of which is connected to the parallel turret turntable 11 through a first belt 71, and the other output end of the reversing gear set 7 is connected to the vertical turret turntable 211 through a second belt 72. In this embodiment, the parallel turret mechanism 1 and the circulating conveying assembly 21 are simultaneously controlled by a reversing gear set 7, which can ensure that the parallel turret mechanism 1 and the circulating conveying assembly 21 move the cigarette packs synchronously. The output end of the gearbox 8 is connected to at least one push plate 221 via a first connecting rod assembly 81, driving the push plate 221 to move forward and backward. The output end of the gearbox 8 is also connected to at least one top and bottom heating plate 41 via a second connecting rod assembly 82, driving the top and bottom heating plates 41 to move left and right. The output end of the gearbox 8 is also connected to at least one large-surface heating plate 51 via a third connecting rod assembly 83, driving the large-surface heating plate 51 to move up and down.

[0035] When the cigarette pack moves, the gearbox 8 drives the two push plates 221 away from each other, drives the two top and bottom heating plates 41 away from each other, and simultaneously drives the two large-surface heating plates 51 away from each other, so that each heating plate releases the cigarette pack and avoids damage to the cigarette pack during movement by giving way. When the cigarette pack stops, the gearbox 8 drives the two push plates 221 toward each other, drives the two top and bottom heating plates 41 toward each other, and simultaneously drives the two large-surface heating plates 51 toward each other, so that each heating plate presses the cigarette pack and ensures that the cigarette pack is heated evenly. This embodiment uses a gearbox 8 to simultaneously control the side seal shaping assembly 22, the top and bottom shaping assembly, and the large-surface shaping assembly, and can keep the side seal shaping assembly 22, the top and bottom shaping assembly, and the large-surface shaping assembly giving way synchronously.

[0036] In addition, the gear box 8 and the reversing gear set 7 are controlled by the same connecting box 6, which ensures the synchronization of the movement of the cigarette pack and the giving way of the shaping component.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
