Description

Technical Field

[0001] This application relates to the technical field of tobacco sorting and packaging, and particularly to a cigarette bar packaging production line. Background Art

[0002] In the tobacco industry, cigarette bars are usually packaged with plastic films. However, due to the long degradation time of plastic films, they will cause certain pollution to the environment. Therefore, in order to reduce plastic pollution, woven bags can be used instead of plastic films to package cigarette bars.

[0003] Due to factors such as market demand and packaging efficiency, woven bags cannot completely replace plastic films. Therefore, there is a market demand for both cigarette bars packaged with plastic films and those packaged with woven bags. However, at present, the cigarette bar packaging production line only has equipment for packaging cigarette bars with plastic films, resulting in poor flexibility of the packaging methods of the cigarette bar packaging production line and being difficult to meet market demands.

[0106] An embodiment of this application provides a cigarette carton packaging production line, which is used to solve the technical problem of too poor flexibility in the packaging method of the cigarette carton packaging production line.

[0107] In the embodiment of this application, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line includes a first conveying mechanism 1, a film wrapping device 2, a second conveying mechanism 3, a heat shrinkage device 4, a first lifting device 5, a support platform 6, a third conveying mechanism 7, and a bagging device 8. The first conveying mechanism 1 is used to convey the first pallet 1000, and the film wrapping device 2 is docked to the side of the first conveying mechanism 1. The end of the second conveying mechanism 3 is docked to the film wrapping device 2, and the heat shrinkage device 4 is docked to the end of the second conveying mechanism 3 away from the film wrapping device 2. The first lifting device 5 is docked to the side of the first conveying mechanism 1. The first conveying mechanism 1, the film wrapping device 2, the second conveying mechanism 3, and the heat shrinkage device 4 are all arranged below the support platform 6, and the first lifting device 5 extends from below the support platform 6 to above the support platform 6. The third conveying mechanism 7 is arranged on the upper surface of the support platform 6, and one end of the third conveying mechanism 7 is docked to the top of the first lifting device 5. The bagging device 8 is arranged on the upper surface of the support platform 6, and the bagging device 8 is docked to the third conveying mechanism 7. Among them, the first pallet 1000 is used to place cigarette cartons.

[0108] It can be understood that, in terms of spatial position, the devices below the support platform 6 are located on the first floor, and the devices on the upper surface of the support platform 6 are located on the second floor. For example, in this embodiment, the first conveying mechanism 1, the film wrapping device 2, the second conveying mechanism 3, and the heat shrinkage device 4 are all arranged on the first floor, while the third conveying mechanism 7 and the bagging device 8 are both arranged on the second floor.

[0109] The first conveying mechanism 1 is used to convey the first pallet 1000 to convey the first pallet 1000 with cigarette cartons placed thereon to the film wrapping device 2. Among them, the user can manually place the cigarette cartons into the first pallet 1000 on the first conveying mechanism 1, or can place the cigarette cartons into the first pallet 1000 on the first conveying mechanism 1 through automated equipment.

[0110] When the first conveying mechanism 1 conveys the first tray 1000 with cigarette cartons to the docking position between the film wrapping device 2 and the first conveying mechanism 1, the cigarette cartons in the first tray 1000 are pushed into the film wrapping device 2 so that the film wrapping device 2 can wrap the cigarette cartons with plastic film. Among them, the user can manually push the cigarette cartons in the first tray 1000 into the film wrapping device 2, or can push the cigarette cartons into the film wrapping device 2 through automated equipment.

[0111] The cigarette cartons after film wrapping are conveyed by the film wrapping device 2 to the second conveying mechanism 3, and then the second conveying mechanism 3 conveys the cigarette cartons after film wrapping to the heat shrinkage device 4. After the heat shrinkage device 4 receives the cigarette cartons after film wrapping from the second conveying mechanism 3, the heat shrinkage device 4 continues to convey the cigarette cartons after film wrapping so that the cigarette cartons after film wrapping pass through the chamber inside the heat shrinkage device 4. The heat shrinkage device 4 heats the chamber inside it. Therefore, when the cigarette cartons after film wrapping pass through the chamber inside the heat shrinkage device 4, the plastic film wrapped on the cigarette cartons is heated and shrunk to tightly adhere to the surface of the cigarette cartons, thus realizing the packaging of the cigarette cartons with the plastic film.

[0112] Another part of the first tray 1000 with cigarette cartons conveyed by the first conveying mechanism 1 is conveyed to the docking position between the first lifting device 5 and the first conveying mechanism 1. Then the first tray 1000 with cigarette cartons is pushed into the first lifting device 5, and the first lifting device 5 lifts the first tray 1000 with cigarette cartons to the second floor. Then the first lifting device 5 conveys the first tray 1000 lifted to the second floor to the third conveying mechanism 7, so that the third conveying mechanism 7 conveys the first tray 1000 with cigarette cartons to the docking position between the bagging device 8 and the third conveying mechanism 7.

[0113] When the third conveying mechanism 7 conveys the first tray 1000 with cigarette cartons to the docking position between the bagging device 8 and the third conveying mechanism 7, the cigarette cartons in the first tray 1000 are pushed into the bagging device 8 so that the bagging device 8 can bag the cigarette cartons in a woven bag, thus realizing the packaging of the cigarette cartons with the woven bag. Among them, the user can manually push the cigarette cartons in the first tray 1000 into the bagging device 8, or can push the cigarette cartons in the first tray 1000 into the bagging device 8 through automated equipment.

[0114] The first conveying mechanism 1 of the embodiment of the present application is used to convey the first tray 1000, and the first tray 1000 is used to place cigarette cartons. When the first conveying mechanism 1 conveys the first tray 1000 to the docking position of the first lifting device 5 and the first conveying mechanism 1, the first lifting device 5 can lift a part of the first tray 1000 above the support platform 6, and then convey this part of the first tray 1000 to the third conveying mechanism 7. The third conveying mechanism 7 is used to convey the first tray 1000 with cigarette cartons placed therein to the bagging device 8, so as to bag the cigarette cartons conveyed by the first tray 1000 through the bagging device 8, realizing the packaging of the cigarette cartons. Another part of the first tray 1000 will be conveyed by the first conveying mechanism 1 to the film wrapping device 2, so as to wrap the cigarette cartons conveyed by the first tray 1000 through the film wrapping device 2. The cigarette cartons after film wrapping will be conveyed by the second conveying mechanism 3 to the heat shrinkage device 4, so as to heat the plastic film wrapped on the cigarette cartons through the heat shrinkage device 4, making the plastic film closely adhere to the cigarette cartons, realizing the packaging of the cigarette cartons. Since the cigarette cartons can be selectively packaged with woven bags and plastic films according to actual needs, the flexibility of the cigarette carton packaging method can be improved to adapt to market demands. The bagging device 8 is arranged on the upper surface of the support platform 6, so that the factory space can be utilized more reasonably.

[0115] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes an eighth conveying mechanism 800, and the end of the eighth conveying mechanism 800 is docked to the heat shrinkage device 4. After the heat shrinkage device 4 shrinks the plastic film on the cigarette cartons to realize plastic film packaging, it can be conveyed to the blanking position through the eighth conveying mechanism 800.

[0116] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes a ninth conveying mechanism 900, and the end of the ninth conveying mechanism 900 is docked to the bagging device 8. After the bagging device 8 loads the cigarette cartons into the woven bag to realize woven bag packaging, it can be conveyed to the blanking position through the ninth conveying mechanism 900.

[0117] In one embodiment, the cigarette carton packaging production line further includes a second pushing component, and the second pushing component is used to push the first tray 1000 conveyed by the first conveying mechanism 1 into the first lifting device 5.

[0118] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes a fourth conveying mechanism 9 and a cigarette stacking device 10. The fourth conveying mechanism 9 is used to convey cigarette cartons. The cigarette stacking device 10 is docked to the end of the conveying direction of the fourth conveying mechanism 9, and the first conveying mechanism 1 is docked to the cigarette stacking device 10. Among them, both the fourth conveying mechanism 9 and the cigarette stacking device 10 are arranged below the support platform 6.

[0119] After the fourth conveying mechanism 9 conveys the cigarette cartons to the end in its conveying direction, the cigarette stacking device 10 will receive the cigarette cartons conveyed by the fourth conveying mechanism 9, so as to stack the cigarette cartons conveyed by the fourth conveying mechanism 9 in the first tray 1000 conveyed by the first conveying mechanism 1 through the cigarette stacking device 10. After the cigarette cartons are stacked in the first tray 1000 by the cigarette stacking device 10, the stacked cigarette cartons can be packaged.

[0120] In this embodiment, multiple fourth conveying mechanisms 9 and cigarette stacking devices 10 can be provided, and the fourth conveying mechanisms 9 and the cigarette stacking devices 10 are arranged in one-to-one correspondence.

[0121] In one embodiment, the cigarette stacking device 10 includes a first support frame, a first driving unit, a receiving platform, a transfer assembly and a first pushing assembly. The first driving unit is arranged on the first support frame. The receiving platform is arranged at the output end of the first driving unit, and the first driving unit is used to drive the receiving platform to lift and lower. The transfer assembly is arranged on the first support frame, the transfer assembly is located above the receiving platform, and the transfer assembly is used to place the cigarette cartons received from the fourth conveying mechanism 9 on the receiving platform. The first pushing assembly is arranged on the receiving platform, the pushing end of the first pushing assembly is located above the receiving platform, and the pushing end of the first pushing assembly can approach or move away from the first conveying mechanism 1.

[0122] After the transfer assembly receives the cigarette cartons from the fourth conveying mechanism 9, the first driving unit drives the receiving platform to lift and lower to a suitable height, so that the transfer assembly can place the received cigarette cartons on the receiving platform. After multiple cooperations between the transfer assembly and the receiving platform, the cigarette cartons can be stacked on the receiving platform. Then the first driving unit drives the receiving platform to lift and lower to a position at the same height as the first tray 1000 on the first conveying mechanism 1. Then the pushing end of the first pushing assembly pushes the cigarette cartons stacked on the receiving platform into the first tray 1000. After the first pushing assembly pushes the cigarette cartons into the first tray 1000, the pushing end of the first pushing assembly moves in a direction away from the first conveying mechanism 1, so that the transfer assembly can place the cigarette cartons received from the fourth conveying mechanism 9 on the receiving platform.

[0123] In one embodiment, the transfer assembly includes a conveying member, a receiving member and two rotating members. The rotating members are rotatably arranged on the first support frame, and the two rotating members are arranged at intervals in the up and down direction. The conveying member is tensioned between the two rotating members, and the rotating members are used to drive the conveying member to rotate around the rotating members. The receiving member is arranged on the outer surface of the conveying member, and the length direction of the receiving member is perpendicular to the outer surface of the conveying member. Among them, the receiving member can be a plate-like structure, and the conveying member can be a belt-like structure.

[0124] Understandably, the shape of the rotation trajectory of the conveying member is an oval. When the receiving member moves between the two rotating members and is close to the upper position, the length direction of the receiving member is parallel and at the same height as the conveying plane of the fourth conveying mechanism 9, so the cigarette cartons can be conveyed onto the receiving member. Then the conveying member drives the receiving member to move downward until the receiving member passes over the lower rotating member and moves to the other side of the rotating member. During this process, the end of the receiving member will gradually tilt. At this time, the cigarette cartons on the receiving member will slide downward under their own gravity and fall onto the receiving platform. When the distance between the receiving platform and the receiving member is reasonable, the cigarette cartons can stably fall from the receiving member to the receiving platform.

[0125] In one embodiment, a plurality of receiving members are arranged at intervals on the conveying member.

[0126] In one embodiment, two transfer components are provided, and the two transfer components are symmetrically arranged with respect to the vertical plane where the conveying direction of the fourth conveying mechanism 9 is located. The receiving members of the two transfer components are correspondingly arranged at intervals and at the same height, so as to receive and convey the cigarette cartons from the fourth conveying mechanism 9 together through the receiving members of the two transfer components, improving the stability of the receiving members in conveying the cigarette cartons.

[0127] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes a fifth conveying mechanism 20 and a transfer device 30. The fifth conveying mechanism 20 is used for conveying cigarette cartons. The fifth conveying mechanism 20 and the first conveying mechanism 1 are located on the same straight line, and the conveying direction of the fourth conveying mechanism 9 is parallel to the conveying direction of the fifth conveying mechanism 20. The transfer device 30 is connected to the end of the conveying direction of the fifth conveying mechanism 20, and the first conveying mechanism 1 is connected to the transfer device 30. Among them, both the fifth conveying mechanism 20 and the transfer device 30 are arranged below the support platform 6.

[0128] The transfer device 30 is used to receive at least one cigarette carton conveyed by the fifth conveying mechanism 20, so as to place the received cigarette cartons on the first trays 1000 conveyed by the first conveying mechanism 1, so that at least one cigarette carton can be placed in each first tray 1000. By providing the fifth conveying mechanism 20 and the fourth conveying mechanism 9, cigarette cartons of different specifications can be conveyed, and the efficiency of loading the cigarette cartons onto the first trays 1000 can also be improved. The fifth conveying mechanism 20 and the first conveying mechanism 1 are located on the same straight line, which can make full use of the factory space and avoid wasting space.

[0129] In one embodiment, the transfer device 30 includes a second support frame, a second drive unit, and a turning member. The second drive unit is disposed on the second support frame. The turning member is rotatably disposed on the second support frame, and the turning member is connected to the output end of the second drive unit. The second drive unit is configured to drive the turning member to rotate so that the receiving surface of the turning member is flush with the conveying plane of the fifth conveying mechanism 20, or the receiving surface is parallel to the up-down direction. The first conveying mechanism 1 is located directly below the turning member.

[0130] When the second drive unit drives the turning member to rotate so that the receiving surface of the turning member is flush with the conveying plane of the fifth conveying mechanism 20, the fifth conveying mechanism 20 will push at least one cigarette strip onto the receiving surface of the turning member. Then the second drive unit drives the turning member to rotate again so that the receiving surface is parallel to the up-down direction. During this process, the cigarette strips will fall from the turning member into the first tray 1000 below the turning member under the action of their own gravity, realizing the feeding of cigarette strips into the first tray 1000. Among them, the turning member can be a plate-like structure.

[0131] In one embodiment, as Figure 1 and Figure 2 shown, the first lifting device 5 is located between the cigarette stacking device 10 and the film wrapping device 2, or between the transfer device 30 and the film wrapping device 2, to facilitate the conveyance of the first tray 1000 with cigarette strips placed therein into the first lifting device 5. After the cigarette strips in the first tray 1000 are film-wrapped in the film wrapping device 2, they will be separated from the first tray 1000. Among them, the film-wrapped cigarette strips will be conveyed to the second conveying mechanism 3, and the empty first tray 1000 will be continuously conveyed by the first conveying mechanism 1. Therefore, setting the first lifting device 5 between the cigarette stacking device 10 or the transfer device 30 and the film wrapping device 2 can prevent the empty first tray 1000 from being conveyed into the first lifting device 5.

[0132] In one embodiment, as Figure 1 , Figure 2 and Figure 4 shown, the cigarette packaging production line further includes a second lifting device 40 and a third lifting device 50. The second lifting device 40 is docked at the end of the first conveying mechanism 1 in the feeding direction. The third lifting device 50 is docked at one end of the first conveying mechanism 1 away from the second lifting device 40. The first conveying mechanism 1 includes a first conveying layer 11 and a second conveying layer 12. The second conveying layer 12 is located directly below the first conveying layer 11, and the conveying direction of the first conveying layer 11 is opposite to that of the second conveying layer 12.

[0133] In this embodiment, the first tray 1000 with cigarette strips placed therein can be conveyed through the first conveying layer 11, and the empty first tray 1000 can be conveyed through the second conveying layer 12.

[0134] When the first conveying layer 11 conveys the first pallet 1000 with cigarette cartons placed thereon and the second conveying layer 12 conveys the empty first pallet 1000:

[0135] The first conveying layer 11 conveys the first pallet 1000 with cigarette cartons placed thereon to the film wrapping device 2, so that the cigarette cartons in the first pallet 1000 can be film wrapped by the film wrapping device 2, and the film wrapped cigarette cartons are conveyed to the second conveying mechanism 3. At this time, the cigarette cartons are separated from the first pallet 1000, and the first conveying layer 11 will continue to convey the empty first pallet 1000 separated from the cigarette cartons until the empty first pallet 1000 is conveyed to the second lifting device 40. Then, the second lifting device 40 conveys the empty first pallet 1000 downward to the second conveying layer 12, and then the second conveying layer 12 conveys the empty first pallet 1000 from the second lifting device 40 to the third lifting device 50. Then, the third lifting device 50 lifts the empty first pallet 1000 from the second conveying layer 12 to the first conveying layer 11, so as to place cigarette cartons into the lifted empty first pallet 1000, thereby realizing the recycling of the first pallet 1000.

[0136] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes a fourth lifting device 60, and the fourth lifting device 60 extends from below the support platform 6 to above the support platform 6. The bottom of the fourth lifting device 60 is docked to the first conveying mechanism 1, and the top of the fourth lifting device 60 is docked to one end of the third conveying mechanism 7 far from the top of the first lifting device 5.

[0137] When the first lifting device 5 conveys the first pallet 1000 with cigarette cartons placed thereon to the third conveying mechanism 7, and then the third conveying mechanism 7 conveys the first pallet 1000 with cigarette cartons placed thereon to the docking position of the bagging device 8 and the third conveying mechanism 7. Then, the bagging device 8 bags the cigarette cartons in the first pallet 1000, so that the first pallet 1000 is separated from the cigarette cartons. After the first pallet 1000 passes through the bagging device 8, the cigarette cartons in the first pallet 1000 are bagged by the bagging device 8, and only the empty first pallet 1000 is continuously conveyed by the third conveying mechanism 7 to the fourth lifting device 60.

[0138] Based on the fact that the first conveying layer 11 conveys the first pallet 1000 with cigarette cartons placed thereon and the second conveying layer 12 conveys the empty first pallet 1000. The fourth lifting device 60 conveys the empty first pallet 1000 conveyed by the third conveying mechanism 7 downward to the second conveying layer 12, and the second conveying layer 12 conveys the empty first pallet 1000 conveyed by the fourth lifting device 60 to the third lifting device 50, so as to recycle the first pallet 1000 subsequently.

[0139] In another alternative embodiment, the second lifting device 40 extends from below the support platform 6 to above the support platform 6, and the top of the second lifting device 40 is docked at one end of the third conveying mechanism 7 away from the top of the first lifting device 5.

[0140] After the bagging device 8 bags the cigarette cartons in the first tray 1000 conveyed by the third conveying mechanism 7, the cigarette cartons are separated from the first tray 1000. The empty first tray 1000 will continue to be conveyed by the third conveying mechanism 7 to the top of the second lifting device 40, and the empty first tray 1000 conveyed by the third conveying mechanism 7 is conveyed to the first conveying mechanism 1 through the second lifting device 40.

[0141] On the basis that the first conveying layer 11 conveys the first tray 1000 with cigarette cartons placed thereon and the second conveying layer 12 conveys the empty first tray 1000. The second lifting device 40 can convey the empty first tray 1000 conveyed by the third conveying mechanism 7 to the second conveying layer 12, and then convey the empty first tray 1000 to the third lifting device 50 through the second conveying layer 12 for subsequent recycling of the first tray 1000.

[0142] Compared with the embodiment of the foregoing arrangement of the fourth lifting device 60, the solution of this embodiment enables the second lifting device 40 to convey the empty first tray 1000 conveyed by the third conveying mechanism 7 and the empty first tray 1000 conveyed by the first conveying layer 11 downward to the second conveying layer 12 respectively, without the need to additionally provide a fourth lifting device 60.

[0143] In one embodiment, as Figure 2 and Figure 3 shown, the bagging device 8 includes a third support frame 81, a third driving unit 82, a first support plate 83, a fourth driving unit 84, a second support plate 85, a fifth driving unit 86, a suction cup assembly 87 and a sixth driving unit 88. The third driving unit 82 is disposed on the third support frame 81, the first support plate 83 is disposed at the output end of the third driving unit 82, and the third driving unit 82 is used to drive the first support plate 83 to lift. The fourth driving unit 84 is disposed on the third support frame 81, the second support plate 85 is disposed at the output end of the fourth driving unit 84, and the fourth driving unit 84 is used to drive the second support plate 85 to lift. The second support plate 85 is located directly below the first support plate 83, and the lifting trajectory of the second support plate 85 is located on the side of the third conveying mechanism 7. The fifth driving unit 86 is slidably disposed on the third support frame 81, the suction cup assembly 87 is disposed at the output end of the fifth driving unit 86, and the fifth driving unit 86 is used to drive the suction cup assembly 87 to lift. The sixth driving unit 88 is disposed on the third support frame 81, the fifth driving unit 86 is connected to the output end of the sixth driving unit 88, and the sixth driving unit 88 is used to drive the fifth driving unit 86 to slide on the third support frame 81 so that the suction cup assembly 87 approaches or moves away from the first support plate 83.

[0144] The sixth driving unit 88 can drive the fifth driving unit 86 to slide on the third support frame 81, so as to indirectly drive the suction cup assembly 87 to directly above the woven bag. Then the fifth driving unit 86 drives the suction cup assembly 87 to descend, so as to adsorb and grasp the woven bag through the suction cup assembly 87.

[0145] The fourth driving unit 84 can drive the second support plate 85 to move towards the first support plate 83, so as to adjust the distance between the second support plate 85 and the first support plate 83, facilitating the first support plate 83 and the second support plate 85 to extend into the woven bag together.

[0146] Then the fifth driving unit 86 drives the suction cup assembly 87 to lift and lower, so as to adjust the height of the woven bag grasped by the suction cup assembly 87, making the height of the woven bag correspond to the heights of the first support plate 83 and the second support plate 85. Then the sixth driving unit 88 drives the fifth driving unit 86 to move towards the first support plate 83 and the second support plate 85. Since the distance between the first support plate 83 and the second support plate 85 and the height of the woven bag grasped by the suction cup assembly 87 have been adjusted in advance, during the process of the sixth driving unit 88 driving the fifth driving unit 86 to move towards the first support plate 83 and the second support plate 85, the first support plate 83 and the second support plate 85 will extend into the woven bag.

[0147] After the first support plate 83 and the second support plate 85 extend into the woven bag, the suction cup assembly 87 releases the woven bag. Subsequently, the sixth driving unit 88 drives the fifth driving unit 86 to move in a direction away from the first support plate 83 and the second support plate 85. Then the fourth driving unit 84 drives the second support plate 85 to move in a direction away from the first support plate 83, so as to expand the woven bag through the second support plate 85 and the first support plate 83 during the process of increasing the distance between the second support plate 85 and the first support plate 83. After that, the third driving unit 82 drives the first support plate 83 to move downward, and the fourth driving unit 84 drives the second support plate 85 to move downward, enabling the first support plate 83 and the second support plate 85 to move downward synchronously. When the opening of the woven bag expanded by the first support plate 83 and the second support plate 85 is directly opposite to the cigarette cartons in the first tray 1000 conveyed by the third conveying mechanism 7, the third driving unit 82 stops driving the first support plate 83 to descend, and at the same time, the fourth driving unit 84 stops driving the second support plate 85 to descend.

[0148] When the opening of the woven bag expanded by the first support plate 83 and the second support plate 85 is directly opposite to the cigarette cartons in the first tray 1000, the cigarette cartons can be manually pushed from the first tray 1000 into the woven bag to achieve bagging of the cigarette cartons. Or the cigarette cartons in the first tray 1000 can be pushed into the woven bag through automated equipment to achieve bagging of the cigarette cartons.

[0149] In one embodiment, as Figure 2 and Figure 3As shown, the cigarette packaging production line further includes a fourth support frame 70, a seventh drive unit 80, and a push plate 90. The fourth support frame 70 and the third support frame 81 are respectively disposed on either side of the third conveying mechanism 7. The seventh drive unit 80 is disposed on the fourth support frame 70, and the push plate 90 is disposed at the output end of the seventh drive unit 80. The seventh drive unit 80 is used to drive the push plate 90 to move toward or away from the first support plate 83 from above the conveying plane of the third conveying mechanism 7.

[0150] When the opening of the woven bag supported by the first support plate 83 and the second support plate 85 is opposite to the cigarettes in the first tray 1000, the seventh driving unit 80 drives the push plate 90 to push the cigarettes in the first tray 1000 transported by the third conveying mechanism 7 into the woven bag, thereby bagging the cigarettes.

[0151] In one embodiment, the film wrapping device 2 includes a fifth support frame, a conveying platform, an eighth drive unit, a pressure plate, a ninth drive unit, a film cutting unit, a film stretching unit and a tensioning roller. The conveying platform, the eighth drive unit, the ninth drive unit, the film stretching unit and the tensioning roller are all arranged on the fifth support frame, and the conveying platform is connected to the first conveying mechanism 1. The pressure plate is arranged at the output end of the eighth drive unit, and the pressure plate is located directly above the conveying platform. The eighth drive unit is used to drive the pressure plate to move closer to or away from the conveying platform. The film cutting unit is arranged at the output end of the ninth drive unit, and the ninth drive unit is used to drive the film cutting unit to move up and down. The height of the film stretching unit is not higher than the height of the conveying platform, and the film stretching unit, the film cutting unit and the pressure plate are arranged in sequence along the conveying direction of the conveying platform. The tensioning roller is located above the film stretching unit.

[0152] When the first conveying mechanism 1 conveys the first tray 1000 with cigarettes to the docking position between the conveying platform and the first conveying mechanism 1, the cigarettes in the first tray 1000 can be pushed onto the conveying platform manually or by automated equipment.

[0153] The film-stretching unit is used to pull the plastic film down from the tensioning roller so that the plastic film spans the tensioning roller and the film-stretching unit. Since the height of the film-stretching unit is not higher than the height of the conveying platform, and the tensioning roller is located above the film-stretching unit, the film-stretching unit, the film-cutting unit and the pressure plate are arranged in sequence along the conveying direction of the conveying platform. Therefore, in the process of pushing the cigarettes in the first tray 1000 toward the conveying platform, the end of the cigarette away from its stressed end will press against the plastic film and drag the plastic film from the tensioning roller until the cigarette is pushed to the corresponding position of the conveying platform. At this time, the plastic film between the film-stretching unit and the tensioning roller will be tensioned on the end of the cigarette away from its stressed end.

[0154] Then, the eighth driving unit drives the pressing plate to move towards the conveying platform, so as to press the plastic film above the cigarette cartons onto the cigarette cartons through the pressing plate. Subsequently, the ninth driving unit drives the film cutting unit to move downward, so as to cut the plastic film through the film cutting unit, thereby realizing the wrapping of the cigarette cartons. Finally, the conveying platform conveys the wrapped cigarette cartons to the second conveying mechanism 3.

[0155] Understandably, the film cutting unit cuts the plastic film above the cigarette cartons, and at the same time, can also fix the cut end of the plastic film tensioned on the tensioning roller to the film pulling unit, so as to wrap the cigarette cartons in the next first tray 1000.

[0156] In one embodiment, the cigarette carton packaging production line further includes a sixth support frame 51, a tenth driving unit and a pushing member. The tenth driving unit is arranged on the sixth support frame 51. The pushing member is arranged at the output end of the tenth driving unit, and the tenth driving unit is used to drive the pushing member to move in a direction from above the first conveying mechanism 1 towards or away from above the conveying platform.

[0157] When the first conveying mechanism 1 conveys the first tray 1000 with cigarette cartons placed therein to the docking position between the conveying platform and the first conveying mechanism 1, the tenth driving unit is used to drive the pushing member to move towards above the conveying platform, so as to push the cigarette cartons in the first tray 1000 onto the conveying platform through the pushing member.

[0158] In one embodiment, as Figure 1 and Figure 2 shown, the cigarette carton packaging production line further includes a feeding device 100, a sixth conveying mechanism 200, a fifth lifting device 300 and a seventh conveying mechanism 400. The feeding device 100 and the sixth conveying mechanism 200 are both arranged below the support platform 6. The feeding device 100 is docked with the sixth conveying mechanism 200, and the sixth conveying mechanism 200 is used to convey the second tray 2000. The fifth lifting device 300 extends from below the support platform 6 to above the support platform 6, and the feeding end of the sixth conveying mechanism 200 in the feeding direction is docked with the bottom of the fifth lifting device 300. The seventh conveying mechanism 400 is arranged on the upper surface of the support platform 6, and the seventh conveying mechanism 400 is used to convey the second tray 2000. The bagging device 8 is docked with the seventh conveying mechanism 400, and the end of the seventh conveying mechanism 400 is docked with the top of the fifth lifting device 300.

[0159] The second tray 2000 is used for placing textile bags, and the feeding device 100 is used for placing woven bags into the second tray 2000 on the sixth conveying mechanism 200. After the sixth conveying mechanism 200 conveys the second tray 2000 with the woven bag placed therein to the bottom of the fifth lifting device 300, the fifth lifting device 300 then lifts the second tray 2000 with the woven bag placed therein above the support platform 6, and then conveys the second tray 2000 with the woven bag placed therein from the top of the fifth lifting device 300 to the seventh conveying mechanism 400. Then the seventh conveying mechanism 400 conveys the second tray 2000 with the woven bag placed therein to the docking position between the bagging device 8 and the seventh conveying mechanism 400, so that the bagging device 8 can bag the cigarette cartons.

[0160] In an embodiment, the cigarette carton packaging production line further includes a sixth lifting device, which extends from below the support platform 6 to above the support platform 6. The top of the sixth lifting device is docked at one end of the seventh conveying mechanism 400 away from the top of the fifth lifting device 300, and the bottom of the sixth lifting device is docked at one end of the sixth conveying mechanism 200 away from the bottom of the fifth lifting device 300.

[0161] After the bagging device 8 bags the cigarette cartons into the woven bag, the second tray 2000 is separated from the woven bag. At this time, the seventh conveying mechanism 400 continues to convey the empty second tray 2000 to convey the empty second tray 2000 to the top of the sixth lifting device. The sixth lifting device then conveys the empty second tray 2000 from above the support platform 6 to below the support platform 6, and then the sixth lifting device conveys the empty second tray 2000 to one end of the sixth conveying mechanism 200 away from the bottom of the fifth lifting device 300, so as to convey the empty second tray 2000 to the docking position between the feeding device 100 and the sixth conveying mechanism 200 through the sixth conveying mechanism 200. Then the feeding device 100 places the woven bag into the empty second tray 2000, realizing the recycling of the second tray 2000.

[0162] In another alternative embodiment, as Figure 1 and Figure 2As shown in the figure, the cigarette carton packaging production line further includes a seventh lifting device 500, an eighth lifting device 600, and a ninth lifting device 700. The seventh lifting device 500 is disposed on the upper surface of the support platform 6, and the seventh lifting device 500 is docked to one end of the seventh conveying mechanism 400 away from the top of the fifth lifting device 300. The seventh conveying mechanism 400 includes a third conveying layer and a fourth conveying layer. The fourth conveying layer is located directly below the third conveying layer, and the conveying direction of the fourth conveying layer is opposite to the conveying direction of the third conveying layer. The eighth lifting device 600 extends from below the support platform 6 to above the support platform 6. The top of the eighth lifting device 600 is docked to one end of the seventh conveying mechanism 400 away from the seventh lifting device 500, and the bottom of the eighth lifting device 600 is docked to the feeding end of the sixth conveying mechanism 200.

[0163] The ninth lifting device 700 is disposed below the support platform 6, and the ninth lifting device 700 is docked to one end of the sixth conveying mechanism 200 away from the eighth lifting device 600. The sixth conveying mechanism 200 includes a fifth conveying layer and a sixth conveying layer. The sixth conveying layer is located directly below the fifth conveying layer, and the conveying direction of the sixth conveying layer is opposite to the conveying direction of the fifth conveying layer.

[0164] Both the third conveying layer and the fifth conveying layer can be used to convey the second tray 2000 with a woven bag placed thereon, and both the fourth conveying layer and the sixth conveying layer can be used to convey the empty second tray 2000. This embodiment will be described based on this. Of course, both the third conveying layer and the fifth conveying layer can also be used to convey the empty second tray 2000, and both the fourth conveying layer and the sixth conveying layer can also be used to convey the second tray 2000 with a woven bag. This embodiment will not be elaborated here.

[0165] After the third conveying layer conveys the second tray 2000 with a woven bag to the docking position between the bagging device 8 and the third conveying layer, the bagging device 8 loads the cigarettes into the woven bag. At this time, the second tray 2000 is separated from the woven bag, and the third conveying layer continues to convey the empty second tray 2000 to convey the empty second tray 2000 to the seventh lifting device 500.

[0166] The seventh lifting device 500 then conveys the empty second tray 2000 to the fourth conveying layer, and conveys the empty second tray 2000 to the top of the eighth lifting device 600 through the fourth conveying layer. Then the eighth lifting device 600 conveys the empty second tray 2000 from above the support platform 6 to below the support platform 6, and then conveys the empty second tray 2000 to the sixth conveying layer.

[0167] The sixth conveying layer conveys the empty second tray 2000 to the ninth lifting device 700, and the ninth lifting device 700 then lifts the empty second tray 2000 to the fifth conveying layer. The empty second tray 2000 is conveyed through the fifth conveying layer to the docking position between the feeding device 100 and the fifth conveying layer, so that the feeding device 100 can place the woven bags into the second tray 2000. Then the fifth conveying layer conveys the second tray 2000 with the woven bags placed therein to the fifth lifting device 300, and the fifth lifting device 300 lifts the second tray 2000 with the woven bags placed therein from below the support platform 6 to above the support platform 6.

[0168] Then the fifth lifting device 300 conveys the second tray 2000 with the woven bags placed therein to the third conveying layer, so as to convey the woven bags to the docking position between the bagging device 8 and the third conveying layer through the third conveying layer, so as to recycle the second tray 2000.

[0169] By providing the seventh lifting device 500, the eighth lifting device 600 and the ninth lifting device 700, the layout rationality and flexibility of the woven bag conveying line can be improved, so as to improve the utilization rate of the workshop.

[0170] The structures of the sixth conveying mechanism 200 and the seventh conveying mechanism 400 can refer to the first conveying mechanism 1, and the sixth conveying mechanism 200 and the seventh conveying mechanism 400 are not illustrated in this embodiment.

[0171] In one embodiment, as Figure 2 shown, the extending directions of both ends of the seventh conveying mechanism 400 are the same, and both ends of the seventh conveying mechanism 400 are arranged at intervals. It can prevent the seventh conveying mechanism 400 from dividing the workshop in the middle, making it difficult for users to walk from one side of the workshop to the other side. It can also improve the layout rationality and flexibility of the woven bag conveying line, thereby improving the utilization rate of the workshop.

[0172] In one embodiment, as Figure 2 shown, the docking end of the seventh conveying mechanism 400 and the eighth lifting device 600 is located at one end of the docking end of the seventh conveying mechanism 400 and the seventh lifting device 500 away from the third conveying mechanism 7. To improve the layout rationality and flexibility of the woven bag conveying line, thereby improving the utilization rate of the workshop.

[0173] In one embodiment, as Figure 1 and Figure 2 shown, the orthographic projection of the bagging device 8 in the up and down direction overlaps with the orthographic projection of the film wrapping device 2 in the up and down direction, that is, the bagging device 8 is located above the film wrapping device 2. To improve the layout rationality and flexibility of the woven bag conveying line, thereby improving the utilization rate of the workshop.

[0174] In one embodiment, as Figure 1 andFigure 5 As shown in the figure, the first lifting device 5 includes a sixth support frame 51, an eleventh driving unit 52, a lifting member 53, a bearing member 54, a roller 55 and a twelfth driving unit. The eleventh driving unit 52 is disposed on the sixth support frame 51. The lifting member 53 is disposed at the output end of the eleventh driving unit 52, and the eleventh driving unit 52 is used to drive the lifting member 53 to rotate. The shape of the rotation trajectory of the lifting member 53 is an oblong; the rotation trajectories on the opposite sides of the lifting member 53 are parallel, the rotation directions are opposite, and are parallel to the up and down directions. The bearing member 54 is disposed outside the lifting member 53, and the length direction of the bearing member 54 is perpendicular to the up and down directions. The roller 55 is rotatably disposed on the bearing member 54. The rotation center line of the roller 55 is perpendicular to the up and down directions and the length direction of the bearing member 54. The roller 55 can be docked with the first conveying mechanism 1 or the third conveying mechanism 7. The twelfth driving unit is disposed on the bearing member 54, and the roller 55 is connected to the output end of the twelfth driving unit. The twelfth driving unit is used to drive the roller 55 to rotate.

[0175] Wherein, the lifting member 53 can be a strip structure or a chain structure.

[0176] The first conveying mechanism 1 or the third conveying mechanism 7 can convey the first tray 1000 to the roller 55. When the first tray 1000 just contacts the roller 55, the twelfth driving unit can drive the roller 55 to rotate so as to completely support the first tray 1000 through the roller 55. Then the eleventh driving unit 52 drives the lifting member 53 to rotate to drive the bearing member 54 to lift and lower through the lifting member 53. After the first tray 1000 on the roller 55 is driven by the lifting member 53 to lift and lower to a preset position, the twelfth driving unit drives the roller 55 to rotate again to convey the first tray 1000 on the roller 55 to the first conveying mechanism 1 or the third conveying mechanism 7, realizing the lifting and conveying of the first tray 1000.
