Description

Technical Field

[0001] This utility model relates to the technical field of cigarette pack shaping devices, specifically to a vertical turret side sealing shaping device. Background Technology

[0002] In the field of cigarette packaging machinery, traditional cigarette pack shaping technology focuses on heat sealing and pressing the top and bottom surfaces, lacking simultaneous shaping treatment for the sides and ends. Existing equipment mostly uses a turret structure with a vertical axis arrangement. The upper and lower heating plates can only achieve large-area pressing of the top and bottom surfaces, causing the side seals to rely on the natural shrinkage of the material, easily resulting in wrinkles and incomplete seals. The ends, lacking a pressing mechanism, suffer from edge curling. Although some solutions attempt to add fixed heating plates on both sides of the conveyor channel, the turret structure layout and movement synchronization limitations make it difficult to dynamically adjust the spacing between the heating plates, and there is a safety hazard that the heat source cannot be quickly avoided when the machine stops.

[0003] Existing improved technologies generally suffer from bottlenecks such as low space utilization and difficulty in coordinating control of multiple mechanisms: fixed side-sealing heating plates cannot be adapted to different specifications of cigarette packs, and forcibly adding side-sealing stations increases the length of the equipment; the timing conflict between the intermittent movement of the heating plate and the turret can easily cause mechanical interference, and frequent shutdowns for adjustments seriously affect production efficiency. In addition, traditional solutions do not establish an emergency heat source avoidance mechanism, and when the equipment stops abnormally, the high-temperature heating plate continues to contact the cigarette pack, posing a risk of scalding the packaging material or even causing a fire. Utility Model Content

[0004] Based on the above description, this utility model provides a vertical turret side sealing and shaping device. Through the coordinated design of the vertical turret and the side sealing and shaping mechanism, the heating components on both sides of the vertical turret are used to simultaneously complete the heat sealing of the long sides of the cigarette pack. The overall structure achieves seamless connection between the side sealing station and the conveying channel in a compact space, taking into account both the side sealing and shaping efficiency and the safety of equipment operation.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A vertical turret side sealing shaping device, comprising a vertical turret and a side sealing shaping mechanism;

[0007] The vertical turret includes a vertical turntable and multiple molds. The rotation axis of the vertical turntable is set horizontally. The molds are evenly spaced along the circumference of the vertical turntable. A mold channel with open sides is formed between two adjacent molds. The vertical turntable rotates intermittently according to the included angle between two adjacent mold channels.

[0008] The side-sealing and shaping mechanism includes a support base, a fixed bracket, two heating components, and a drive module. The fixed bracket is disposed on the support base and located on the radial outer side of the vertical turntable. Each heating component includes a push plate and a heating plate. The two push plates are respectively disposed on both sides of the fixed bracket and are movably disposed along the axial direction of the vertical turntable. The heating plate is correspondingly connected to the push plate. At least one mold channel is distributed between two corresponding heating plates. The drive module is connected to at least one push plate to adjust the corresponding heating plate to move closer to or further away from the vertical turntable.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0010] The vertical turret side-sealing and shaping device provided in this application effectively solves the technical problem of missing side-sealing shaping in existing technologies through the coordinated design of the vertical turret and the side-sealing and shaping mechanism. The horizontally oriented vertical turret releases lateral space, and the heating components on both sides can simultaneously complete the heat sealing of the long sides of the cigarette pack, significantly improving the sealing performance and appearance consistency of the cigarette pack. The circumferentially evenly distributed box molds form an intermittently rotating box mold channel, which is precisely aligned with the heating plate when the turret is stationary, ensuring that the long sides of the cigarette pack are simultaneously heated and pressed together, effectively eliminating side-sealing wrinkles and incomplete sealing defects. The overall structure achieves seamless connection between the side-sealing station and the conveying channel within a compact space, balancing side-sealing and shaping efficiency with equipment operation safety.

The second arm is connected to one end of the side sealing link. The other end of the side sealing link is driven to be connected to the intermittent drive source. The intermittent drive source drives the side heating swing arm to swing intermittently through the side sealing link, so that the sliding support drives the push plate away from the vertical turntable.

[0015] Furthermore, the intermittent drive source includes a chassis, a cam, and a side sealing cam swing arm. The cam drive is installed at the output end of the chassis. One end of the side sealing cam swing arm is provided with a cam bearing that abuts against the outer peripheral surface of the cam.

[0031] like Figure 1 As shown, this application provides a vertical turret side sealing shaping device, which includes a vertical turret 10 and a side sealing shaping mechanism 20.

[0032] Among them, combined Figure 2 As shown, the vertical turret 10 includes a vertical turntable 11 and multiple molds 12. The rotation axis of the vertical turntable 11 is set horizontally, and the molds 12 are evenly spaced along the circumference of the vertical turntable 11. A mold channel 13 with open sides is formed between two adjacent molds 12. The vertical turntable 11 rotates intermittently according to the included angle of two adjacent mold channels 13.

[0033] The side sealing and shaping mechanism 20 includes a support base 21, a fixed bracket 22, two heating components 23, and a drive module 24. The fixed bracket 22 is disposed on the support base 21 and located on the radial outer side of the vertical turntable 11. Each heating component 23 includes a push plate 231 and a heating plate 232. The two push plates 231 are respectively disposed on both sides of the fixed bracket 22 and are movably disposed along the axial direction of the vertical turntable 11. The heating plate 232 is correspondingly connected to the push plate 231. At least one mold channel 13 is distributed between two corresponding heating plates 232. The drive module 24 is connected to at least one push plate 231 to adjust the corresponding heating plate 232 to move closer to or further away from the vertical turret 10.

[0034] This vertical turret side-sealing and shaping device effectively solves the technical problem of missing side-sealing shaping in existing technologies through the coordinated design of the vertical turret 10 and the side-sealing and shaping mechanism 20. The horizontally oriented vertical turntable 11 releases lateral space, and the heating components 23 on both sides can simultaneously heat-seal the long sides of the cigarette pack, significantly improving the sealing performance and appearance consistency of the cigarette pack. The circumferentially evenly distributed box molds 12 form intermittently rotating box mold channels 13, which are precisely aligned with the heating plates 232 when the vertical turret 10 is stationary, ensuring that the long sides of the cigarette pack are simultaneously heated and pressed together, effectively eliminating side-sealing wrinkles and incomplete sealing defects. The overall structure achieves seamless connection between the side-sealing station and the conveying channel within a compact space, balancing side-sealing and shaping efficiency with equipment operation safety.

[0035] The drive module 24 includes a close drive assembly 241 that continuously drives the push plate 231 close to the fixed bracket 22 and a distant drive assembly 242 that intermittently drives the push plate 231 away from the fixed bracket 22. Through the synergistic effect of the two drive assemblies, the heating plate 232 is precisely controlled, ensuring stable side sealing pressure and reliable operation.

[0036] Specifically, a guide shaft 221 is provided on the fixed bracket 22, and the push plate 231 is movably fitted on the guide shaft 221. Near the drive assembly 241, there is a tension spring 2411 fitted on the guide shaft 221. The two ends of the tension spring 2411 are respectively connected to the fixed bracket 22 and the push plate 231. By utilizing the elastic reset characteristics of the tension spring 2411, the drive structure is simplified and the reset accuracy of the heating plate 232 is improved.

[0037] One of the push plates 231 has a sliding support 233 on its outer side. The sliding support 233 has a transversely arranged dial hole 2331 inside. The part away from the drive assembly 242 includes a side heating swing arm 2421, a side sealing link 2422, and an intermittent drive source 2423. The side heating swing arm 2421 includes an arm shaft 24211 and a first arm 24212 and a second arm 24213 disposed on the outer side of the arm shaft 24211. A swing arm seat 211 is provided on the support base 21. The arm shaft 24211 is rotatably disposed on the swing arm seat 211. The first arm 24212 and the second arm 24213 are connected to the arm shaft 24211. The two arms 24213 form a predetermined angle with each other. The first arm 24212 is set in the dial hole 2331. The second arm 24213 is connected to one end of the side sealing link 2422. The other end of the side sealing link 2422 is connected to the intermittent drive source 2423. The intermittent drive source 2423 drives the side heating swing arm 2421 to swing intermittently through the side sealing link 2422, so that the sliding support 233 drives the push plate 231 away from the vertical turntable 11. Through the linkage design of the swing arm and the link, the heating plate 232 can be quickly moved aside to avoid interference with the movement of the turret.

[0038] In the embodiments of this application, the intermittent drive source 2423 includes a housing 24231, a cam 24232, and a side sealing cam swing arm 24233. The cam 24232 is driven and installed at the output end of the housing 24231. One end of the side sealing cam swing arm 24233 is provided with a cam bearing 24234 that abuts against the outer peripheral surface of the cam 24232. The other end of the side sealing cam swing arm 24233 is hinged to the end of the side sealing connecting rod 2422 away from the second arm 24213. The precise contour of the cam is used to control the displacement timing of the heating plate 232 to ensure that the action is precisely synchronized with the intermittent rotation of the turret.

[0039] Preferably, the side sealing shaping mechanism 20 further includes two side sealing start-stop components 25 installed in a one-to-one correspondence with the two heating components 23. The side sealing start-stop component 25 includes a side sealing start-stop cylinder 251 and a start-stop connecting plate 252. The side sealing start-stop cylinder 251 is installed on the fixed bracket 22. The start-stop connecting plate 252 is connected between the output end of the side sealing start-stop cylinder 251 and the corresponding push plate 231. The extension and retraction direction of the side sealing start-stop cylinder 251 is set along the axial direction of the vertical turntable 11. Through the rapid response characteristics of the cylinder, the heating plate 232 can be safely avoided when the equipment is started and stopped, eliminating the risk of high temperature burn.

[0040] Each heating component 23 includes multiple heating plates 232. In this embodiment, there are two heating plates 232. The two heating plates 232 are arranged one-to-one with the multiple mold channels 13 of the vertical turret 10. Through the division of labor and cooperation of the two heating plates, the dual shaping and continuity of the side sealing shaping are improved, and the shaping efficiency is guaranteed.

[0041] In this embodiment, the box mold channel 13 is configured to accommodate two stacked cigarette packs, thereby improving the production efficiency of the equipment through simultaneous shaping of the two cigarette packs.

[0042] The usage process of the above-mentioned vertical turret side seal shaping device is as follows:

[0043] First, the vertical turntable 11 is horizontally positioned, with its circumferentially distributed box molds 12 forming box mold channels 13 with openings on both sides. The cigarette packs enter the workstation through the box mold channels 13. The turntable 11 rotates intermittently at the angle between adjacent channels. When stationary, the box mold channels 13 are precisely aligned with the heating plates 232 of the side sealing and shaping mechanism 20, and the two cigarette packs enter the space between the two heating plates 232 simultaneously. Each heating component 23 includes upper and lower heating plates 232. The tension spring 2411 continuously pulls the push plate 231 to press the heating plates 232 against the long side of the cigarette pack for heat sealing. The cam 24232 drives the side heating swing arm 2421 to swing through the side sealing connecting rod 2422, pushing the sliding support 233 to move the heating plates 232 away from the cigarette pack quickly, making way for the rotation of the turret. The profile of the cam 24232 is strictly synchronized with the intermittent movement of the turret, ensuring that the heating plates 232 are reset and pressed when the turret is stationary.

[0044] The side-sealing start-stop cylinder 251 is axially arranged along the turntable 11. When the machine stops, the cylinder 251 is pushed out, and the push plate 231 and the heating plate 232 are driven away from the tobacco pack channel by the start-stop connecting plate 252 to avoid high temperature burns. When the machine starts, the cylinder 251 is retracted, and the heating plate 232 is reset to the pressing position under the action of the spring 2411 to ensure the safety of the start-stop process.

[0045] The two cigarette packs enter different workstations twice during the intermittent rotation of the turret. The upper and lower heating plates 232 press the long side of the cigarette pack twice to eliminate false sealing and wrinkles. The dual-workstation design and the dual heating plates 232 of the heating component 23 work together to achieve continuous shaping, which significantly improves production efficiency.

[0046] 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.
