The carton packaging equipment includes a wrapping process during the packaging of cartons of cigarettes, using a carton wrapping device to wrap the stacked cartons of cigarettes.

[0003] Currently, most cigarette wrapping devices on the market, after wrapping the cigarettes, typically lower the upper cutter while keeping the lower cutter stationary, allowing the upper cutter to press the film against the lower cutter, thus cutting the film. However, the upper cutter in this type of cigarette wrapping device has a long stroke, resulting in a longer film-cutting time and affecting the wrapping efficiency. Utility Model Content

[0026] This application provides a wrapping device and packaging equipment to solve the technical problem of low wrapping efficiency in wrapping devices.

[0027] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the wrapping device includes a support frame 1, a first drive unit 2, a transmission unit 3, a first cutter 4, a second cutter 5, a conveying unit 6, a wrapping platform 7, and a pushing mechanism 8. The first drive unit 2, the transmission unit 3, and the pushing mechanism 8 are all mounted on the support frame 1. The transmission unit 3 is connected to the output end of the first drive unit 2. The first cutter 4 and the second cutter 5 are both connected to the transmission unit 3. The second cutter 5 is located directly below the first cutter 4. The first drive unit 2 drives the first cutter 4 and the second cutter 5 to move synchronously towards or away from each other via the transmission unit 3. The conveying unit 6 is located on one side of the plane containing the lifting trajectory of the second cutter 5, and the wrapping platform 7 is located on the side of the plane containing the lifting trajectory of the second cutter 5 away from the conveying unit 6. The output end of the pushing mechanism 8 can reciprocate directly above the conveying unit 6 and directly above the wrapping platform 7.

[0028] The second cutter 5 is located directly below the first cutter 4, and the first cutter 4 and the second cutter 5 can move toward each other or toward each other, so that the first cutter 4 and the second cutter 5 can move up and down in the same vertical plane.

[0029] The conveying unit 6 is located on one side of the plane containing the lifting trajectory of the second cutter 5, and the wrapping platform 7 is located on the side of the plane containing the lifting trajectory of the second cutter 5 away from the conveying unit 6, so that the conveying unit 6 and the wrapping platform 7 are located on opposite sides of the plane containing the lifting trajectory of the second cutter 5. The conveying unit 6 can be a conveyor belt.

[0030] The conveying unit 6 is used to convey stacked cigarette packs 40. When the conveying unit 6 has conveyed the stacked cigarette packs 40 to a position directly opposite the wrapping platform 7, the conveying unit 6 stops conveying the cigarette packs 40. Then, the output end of the pushing mechanism 8 pushes the cigarette packs 40 from the conveying unit 6 onto the wrapping platform 7. The direction in which the conveying unit 6 conveys the cigarette packs 40 is perpendicular to the direction in which the pushing mechanism 8 pushes the cigarette packs 40.

[0031] The film 50 can be tensioned between the plane of the lifting trajectory of the second cutter 5 and the conveying unit 6. During the process of the pushing mechanism 8 pushing the cigarette pack 40 from the conveying unit 6 to the wrapping platform 7, the cigarette pack 40 pushes the film 50, causing the film 50 to wrap around the cigarette pack 40 from the side closest to the wrapping platform 7, thus achieving the wrapping of the cigarette pack 40. Then, the first cutter 4 and the second cutter 5 are controlled to move closer together, so that the film 50 is cut and welded by the first cutter 4 and the second cutter 5, completing the entire wrapping process of the cigarette pack 40.

[0032] In this embodiment, the conveying unit 6 is used to convey stacked cigarette packs 40, and the pushing mechanism 8 is used to push the cigarette packs 40, which are directly opposite the wrapping platform 7, from the conveying unit 6 to the wrapping platform 7. During the process of the pushing mechanism 8 pushing the cigarette packs 40 from the conveying unit 6 to the wrapping platform 7, the cigarette packs 40 push the film 50 located between the plane of the lifting trajectory of the second cutter 5 and the conveying unit 6, so that the film 50 covers the cigarette packs 40. The second cutter 5 is located directly below the first cutter 4. The first driving unit 2 can drive the first cutter 4 and the second cutter 5 to move synchronously in a direction that is closer to or farther from each other through the transmission unit 3, so as to use the first cutter 4 and the second cutter 5 to cut and weld the film 50, and complete the wrapping process of the cigarette packs 40. When cutting the film 50, the first cutter 4 and the second cutter 5 move synchronously, which can reduce the driving force of driving a single first cutter 4 or second cutter 5; reduce the stroke of a single first cutter 4 or second cutter 5, so as to reduce the time of cutting the film 50, thereby improving the wrapping efficiency.

[0033] In one embodiment, the pushing mechanism 8 includes a second driving unit and a push plate. The push plate is disposed at the output end of the second driving unit. The second driving unit is used to drive the push plate to reciprocate above the conveying unit 6 and above the wrapping platform 7, so as to push the cigarette pack 40 from the conveying unit 6 to the wrapping platform 7.

[0034] In one embodiment, such as Figure 2 and Figure 3 As shown, the transmission unit 3 includes a first sprocket 31, a second sprocket 32, and a transmission chain 33. Both the first sprocket 31 and the second sprocket 32 ​​are rotatably mounted on the support frame 1, with the second sprocket 32 ​​located directly below the first sprocket 31. The transmission chain 33 is driven by the first sprocket 31 and the second sprocket 32. The output end of the first drive unit 2 is connected to the transmission chain 33, the first sprocket 31, or the second sprocket 32, and the first drive unit 2 is used to drive the transmission chain 33 to rotate. A first cutting blade 4 is disposed on one side of the transmission chain 33, and a second cutting blade 5 is disposed on the other side of the transmission chain 33.

[0035] The second sprocket 32 ​​is located directly below the first sprocket 31. The drive chain 33 is connected to the first sprocket 31 and the second sprocket 32 ​​so that when the drive chain 33 rotates, both sides of the drive chain 33 can move vertically. The first cutter 4 is disposed on one side of the drive chain 33, and the second cutter 5 is disposed on the other side of the drive chain 33. When the first drive unit 2 drives the drive chain 33 to rotate, both sides of the drive chain 33 can drive the first cutter 4 and the second cutter 5 to move synchronously in opposite directions, thereby reducing the stroke of a single first cutter 4 or second cutter 5 and the driving force required to drive a single first cutter 4 or second cutter 5.

[0036] Understandably, the two sides of the transmission chain 33 refer to the two segments of the same transmission chain 33 located between the first sprocket 31 and the second sprocket 32.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, the transmission unit 3 is provided in two sets, and the two sets of transmission units 3 are arranged at intervals along the conveying direction of the conveying unit 6, so that the two ends of the first cutter 4 and the second cutter 5 are respectively set on the transmission chain 33 of the two sets of transmission units 3, thereby improving the stability of the movement of the first cutter 4 and the second cutter 5.

[0038] In one embodiment, such as Figure 2 and Figure 3 As shown, the transmission unit 3 also includes a sliding rod 34, a first slider 35, and a second slider 36. The sliding rod 34 is mounted on the support frame 1, and its length direction is parallel to the vertical direction. Both the first slider 35 and the second slider 36 are slidably mounted on the sliding rod 34. The first slider 35 is located on one side of the transmission chain 33, and the first cutter 4 is located on the first slider 35. The second slider 36 is located on the other side of the transmission chain 33, and the second cutter 5 is located on the second slider 36.

[0039] The length direction of the sliding rod 34 is parallel to the vertical direction, allowing the first slider 35 and the second slider 36 to slide vertically on the sliding rod 34, thereby enabling the first cutter 4 and the second cutter 5 to move vertically. The first slider 35 facilitates the sliding of the first cutter 4 onto the sliding rod 34, and the second slider 36 facilitates the sliding of the second cutter 5 onto the sliding rod 34. By using the first slider 35 and the second slider 36 to slide the first cutter 4 and the second cutter 5 onto the sliding rod 34 respectively, the movement direction of the first cutter 4 and the second cutter 5 is guided, and the stability of the movement of the first cutter 4 and the second cutter 5 is improved.

[0040] In one embodiment, such as Figures 1 to 3As shown, the first slider 35 or the second slider 36 is connected to the output end of the first drive unit 2. The first drive unit 2 is used to drive the first slider 35 or the second slider 36 to slide vertically on the sliding rod 34. The first drive unit 2 can be a cylinder.

[0041] The first driving unit 2 drives the first slider 35 or the second slider 36 to slide vertically on the sliding rod 34. The structure is relatively simple and the accuracy is relatively high.

[0042] In one embodiment, such as Figure 2 and Figure 3 As shown, the wrapping device also includes a mounting rod 30, which is disposed on the support frame 1 and located within the transmission chain 33. The length direction of the mounting rod 30 is parallel to the conveying direction of the conveying unit 6. The first drive unit 2 is disposed on the mounting rod 30 to make the connection structure between the first drive unit 2 and the transmission unit 3 more compact. The mounting rod 30 is located directly above the first cutter 4 or directly below the second cutter 5.

[0043] In one embodiment, such as Figure 1 and Figure 2 As shown, the film-wrapping device also includes a first film-feeding roller 9 and a second film-feeding roller 10, both of which are rotatably mounted on the support frame 1. The mounting height of the second film-feeding roller 10 on the support frame 1 is lower than the support height of the first film-feeding roller 9 on the support frame 1.

[0044] The first film-feeding roller 9 is used to feed the film 50, so that the film 50 fed by the first film-feeding roller 9 wraps around from above the cigarette pack 40 to the plane between the lifting and lowering trajectory of the conveying unit 6 and the second cutter 5. The second film-feeding roller 10 is used to feed the film 50, so that the film 50 fed by the second film-feeding roller 10 wraps around from below the conveying unit 6 to the plane between the lifting and lowering trajectory of the conveying unit 6 and the second cutter 5. The film 50 fed by the first film-feeding roller 9 and the film 50 fed by the second film-feeding roller 10 are fused together between the plane between the lifting and lowering trajectory of the conveying unit 6 and the second cutter 5.

[0045] When the film 50 is cut by the first cutter 4 and the second cutter 5, the first cutter 4 and the second cutter 5 simultaneously weld the cut ends of the film 50 together, so that the two cut ends of the film 50 covering the cigarette pack 40 are welded together, and the cut ends of the film 50 fed by the first film feeding roller 9 and the second film feeding roller 10 are welded together. By feeding the film 50 by the first film feeding roller 9 and the second film feeding roller 10 respectively, the structure of covering the film 50 on the cigarette pack 40 can be simplified.

[0046] In one embodiment, the wrapping device further includes a first support rod and a second support rod, both of which are rotatably mounted on the support frame 1. The first support rod is located between the vertical plane of the conveying unit 6 near the wrapping platform 7 and the plane of the lifting trajectory of the first cutter 4, and the height of the first support rod on the support frame 1 is higher than the maximum lifting height of the first cutter 4. The second support rod is located between the vertical plane of the conveying unit 6 near the wrapping platform 7 and the plane of the lifting trajectory of the second cutter 5, and the height of the second support rod on the support frame 1 is lower than the bottom height of the conveying unit 6.

[0047] The first support rod supports the film 50 fed by the first film feeding roller 9, ensuring that the film 50 avoids the conveying unit 6 and the cigarette packs 40 conveyed by the conveying unit 6, thereby preventing the film 50 from sagging due to its own weight and interfering with the conveying unit 6's conveying of the cigarette packs 40. The second support rod supports the film 50 fed by the second film feeding roller 10, ensuring that the film 50 avoids the bottom of the conveying unit 6, thereby preventing the film 50 from interfering with the conveying unit 6's conveying of the cigarette packs 40.

[0048] In one embodiment, the first cutter 4 and the second cutter 5 are both hot or cold cutters, so as to cut the film 50 and simultaneously weld the cut edges of the film 50 to achieve continuous film wrapping.

[0049] A hot cutter refers to a cutting tool that is heated to a specific temperature, using the combined effect of high temperature and mechanical force to cut the film 50. The film 50 is cut by molten material in the cutting area, combined with cutting edge pressure. Typically, a heating element is installed inside the cutting tool to heat the first cutter 4 and the second cutter 5.

[0050] A cold knife is a cutting tool that cuts at room temperature. It relies on mechanical force to act directly on the film 50, achieving material separation or shaping through physical contact between the cutting edge and the material. The pressure of the cold knife can cut the film 50, and the shearing force of the cold knife can be used to splice the cut edges of the film 50.

[0051] In one embodiment, such as Figure 1 and Figure 2 As shown, the wrapping device also includes partitions 20, which are spaced apart on the upper surface of the conveying unit 6 along the conveying direction of the conveying unit 6. The partitions 20 can separate the stacked cigarette packs 40 to prevent the distance between different stacks of cigarette packs 40 from being too close, which would affect the wrapping of the cigarette packs 40.

[0052] In one embodiment, such as Figure 1 and Figure 2As shown, the upper surface of the wrapping platform 7 can move toward the side opposite to the conveying unit 6 to transport the wrapped cigarette packs 40 to the next process via the wrapping platform 7. The wrapping platform 7 can be a conveyor belt.

[0053] Furthermore, this application also provides a packaging device, which includes a wrapping device. The specific structure of the wrapping device is as described in the above embodiments. Since the packaging device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0054] In one embodiment, the packaging equipment further includes a cigarette stacking device.

[0055] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
