Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, and specifically to an anti-rolling device for aluminum foil paper conveying. Background Technology

[0002] Aluminum foil, used as the inner lining of cigarette boxes, primarily serves to protect the cigarettes from moisture and also prevents external odors from entering the cigarettes, thus maintaining the original tobacco flavor of the cigarettes inside the box.

[0003] There is a certain distance between the aluminum foil and the outer packaging machine. The aluminum foil is conveyed to the outer packaging machine by multiple conveyor rollers to form cigarette boxes. During production, it was found that because the conveyor rollers are straight rollers, the aluminum foil can move back and forth along the axial direction of the conveyor rollers. This causes a slight deviation in the angle at which the aluminum foil enters the outer packaging machine. Due to this slight deviation in the angle of entry, the aluminum foil abuts against the inner wall of the aluminum foil channel inside the outer packaging machine, resulting in curling edges and substandard quality cigarette boxes. Furthermore, this slight deviation in the angle of entry causes misalignment between the aluminum foil and the outer packaging paper. When the outer packaging machine detects this misalignment, it stops, affecting cigarette box production. Utility Model Content

[0004] This application provides an aluminum foil conveying anti-curling device, which aims to ensure that the aluminum foil enters the outer packaging machine at a predetermined angle during the conveying process, so that the aluminum foil is aligned with the cigarette pack paper, thereby reducing the number of times the outer packaging machine stops and reducing the curling of the aluminum foil.

[0005] In one embodiment, an anti-curling device for aluminum foil conveying is provided, comprising:

[0006] The main frame has strip-shaped working positions;

[0007] The rotating components are multiple in number and are arranged sequentially at intervals on the main frame, extending along the extension direction of the working position; each rotating component is rotatably connected to the main frame; and each rotating component is arranged sequentially in an arc shape.

[0008] The main frame is located at the entrance of the outer packaging machine. The aluminum foil enters the outer packaging machine only after passing through the main frame.

[0009] In one embodiment, the rotating component includes a roller and a support component; there are two support components, located at both ends of the rotating shaft of the roller; the rotating shaft is rotatably connected to the support component, and the support component is fixedly connected to the main frame.

[0010] In one embodiment, the support includes a housing, a spring, and a connecting block; the housing is fixedly connected to the main frame, and both the spring and the connecting block are located inside the housing; one end of the spring is fixedly connected to the housing, and the other end is fixedly connected to the connecting block; the connecting block is slidably connected to the inner wall of the housing, and the connecting block is rotatably connected to the rotating shaft.

[0011] In one embodiment, the main frame is a plate, and the working position is one side of the plate; the working position has an arc-shaped surface; multiple mounting slots are arranged sequentially on the working position; the rotating component is rotatably disposed within the mounting slot.

[0012] In one embodiment, the depth direction of the mounting groove is perpendicular to the tangent of the arc-shaped working position.

[0013] In one embodiment, the depth of the mounting groove is greater than the diameter of the roller; the roller is telescopically movable within the mounting groove.

[0014] In one embodiment, a portion of the roller extends out of the mounting groove without the application of external force.

[0015] In one embodiment, the main frame includes support blocks and telescopic components; the extension direction of the telescopic components is the working position; there are two support blocks, which are spaced apart; the telescopic components are fixedly connected to both support blocks to push the two support blocks to move away from or closer to each other; each rotating component is sequentially hinged, and the two rotating components at both ends are respectively rotatably connected to the two support blocks; the rotating components between the two support blocks are sequentially arranged in an arc shape.

[0016] In one embodiment, all the rotating components are sequentially hinged together by hinges.

[0017] Specifically, the hinge includes two connecting pieces and a hinge shaft. Both connecting pieces are rotatably connected to the hinge shaft, and each connecting piece is fixedly connected to two adjacent outer shells in a one-to-one correspondence.

[0018] In one embodiment, the telescopic component includes a threaded cylinder and two threaded rods; the two threaded rods are threadedly engaged with the two ends of the threaded cylinder; the two threaded rods are fixedly connected to the two support blocks respectively.

[0019] Specifically, the threads near the two ends of the threaded cylinder rotate in opposite directions.

[0020] The beneficial effects of this application are:

[0021] After passing through the main frame, the aluminum foil enters the outer packaging machine. On the end face of the main frame closest to the aluminum foil, a rotating component contacts the end face of the aluminum foil. Because the rotating components are arranged in an arc shape, the aluminum foil adheres to the rotating components in an arc shape as well. This arc shape increases the resistance to the aluminum foil moving towards both sides of the arc, thus ensuring that the aluminum foil enters the outer packaging machine at a predetermined angle. This aligns the aluminum foil with the cigarette pack paper, reducing machine downtime and minimizing foil curling.

[0022] Since the aluminum foil is in contact with the rotating part, and the rotating part rotates as the aluminum foil moves, the friction between the aluminum foil and the rotating part is rolling friction. Therefore, the frictional resistance between the aluminum foil and the rotating part can be reduced, and the wear of the aluminum foil by the rotating part can be reduced.

[0036] This application proposes improvements and innovations, and presents the following embodiments.

[0037] In some implementations, please refer to Figures 1 to 4 A device for preventing aluminum foil from curling during conveying is provided, comprising:

[0038] Main frame 1, the main frame 1 has a strip-shaped working position 11;

[0039] Rotating component 2, there are multiple rotating components 2, which are arranged sequentially and at intervals on the main frame 1 and extend along the extension direction of the working position 11; each rotating component 2 is rotatably connected to the main frame 1; each rotating component 2 is arranged sequentially in an arc shape.

[0040] The main frame 1 is located at the entrance of the outer casing 221 packaging machine. The aluminum foil 3 enters the outer casing 221 packaging machine only after passing through the main frame 1.

[0041] Aluminum foil 3 enters the outer casing 221 packaging machine after passing through the main frame 1. On one end face of the main frame 1 near the aluminum foil 3, the rotating part 2 is in contact with the end face of the aluminum foil 3. Since the rotating parts 2 are arranged in an arc shape, the aluminum foil 3 is also arc-shaped when it is attached to the rotating parts 2. The arc shape of the aluminum foil 3 increases the resistance to the movement of the aluminum foil 3 to both sides of the arc, thus allowing the aluminum foil 3 to enter the outer casing 221 packaging machine at a predetermined angle. This ensures that the aluminum foil 3 is aligned with the cigarette pack paper, reduces the number of times the outer casing 221 packaging machine stops, and reduces the curling of the aluminum foil 3.

[0042] Since the aluminum foil 3 is in contact with the rotating part 2, and the rotating part 2 rotates as the aluminum foil 3 moves, the friction between the aluminum foil 3 and the rotating part 2 is rolling friction. Therefore, the frictional resistance between the aluminum foil 3 and the rotating part 2 can be reduced, and the wear of the aluminum foil 3 by the rotating part 2 can be reduced.

[0043] In one embodiment, the rotating component 2 includes a roller 21 and a support component 22; there are two support components 22, located at both ends of the rotating shaft 23 of the roller 21; the rotating shaft 23 is rotatably connected to the support component 22, and the support component 22 is fixedly connected to the main frame 1. The rotating component 2 has a simple and reasonable structure, distributes forces evenly, and can improve the service life of the rotating component 2.

[0044] In one embodiment, the support member 22 includes a housing 221, a spring 222, and a connecting block 223. The housing 221 is fixedly connected to the main frame 1, and the spring 222 and the connecting block 223 are both located inside the housing 221. One end of the spring 222 is fixedly connected to the housing 221, and the other end is fixedly connected to the connecting block 223. The connecting block 223 is slidably connected to the inner wall of the housing 221 and rotatably connected to the rotating shaft 23. Supported by the spring 222, when the aluminum foil 3 is pressed onto the roller 21, the spring 222 is compressed to varying degrees according to the force exerted by the aluminum foil 3. The connecting block 223 drives the roller 21 to make corresponding displacements, ensuring that the roller 21 is always in contact with the aluminum foil 3. This ensures a more reasonable curved surface and avoids excessive local stress that could cause the aluminum foil 3 to tear.

[0045] In one embodiment, the main frame 1 is a plate, and the working position 11 is one side of the plate; the working position 11 has an arc-shaped surface; multiple mounting slots 12 are arranged sequentially on the working position 11; the rotating component 2 is rotatably disposed within the mounting slot 12. The main frame 1 has a simple structure, is easy to produce and process, and the mounting slots 12 can provide a reasonable installation position for the rotating component 2.

[0046] In one embodiment, the depth direction of the mounting groove 12 is perpendicular to the tangential surface of the arc-shaped working position 11. When installing the rotating component 2, the axial direction of the roller 21 is perpendicular to the depth direction of the mounting groove 12, thereby allowing the roller 21 to better adhere to the aluminum foil 3 during operation and reducing the local stress on the aluminum foil 3.

[0047] In one embodiment, the depth of the mounting groove 12 is greater than the diameter of the roller 21; the roller 21 can extend and retract within the mounting groove 12. Because the roller 21 can extend and retract within the mounting groove 12, it can adapt to the pressure of the aluminum foil 3 at different positions, ensuring that the roller 21 can better adhere to the aluminum foil 3 and reducing the local stress on the aluminum foil 3.

[0048] Specifically, a receiving groove is provided on the side wall of the mounting groove 12, the support member 22 is located in the receiving groove, and the rotating shaft 23 is movably locked in the receiving groove. The receiving groove extends along the depth direction of the mounting groove 12.

[0049] In one embodiment, a portion of the roller 21 extends out of the mounting groove 12 without external force. The portion extending out of the mounting groove 12 is designed to make contact with the aluminum foil 3, which is a reasonable design.

[0050] In one embodiment, the main frame 1 includes support blocks 13 and telescopic members 14; the telescopic members 14 extend towards the working position 11; there are two support blocks 13, spaced apart; the telescopic members 14 are fixedly connected to both support blocks 13 to push the two support blocks 13 to move away from or towards each other; each rotating member 2 is sequentially hinged, with the two rotating members 2 at each end corresponding to and rotatably connected to the two support blocks 13; the rotating members 2 between the two support blocks 13 are sequentially arranged in an arc shape. By adjusting the telescopic length of the telescopic members 14, the arc shape of the sequentially arranged rotating members 2 can be changed to better adjust to the appropriate arc for conveying the aluminum foil 3. The main frame 1 has a simple structure and reasonable design.

[0051] In one embodiment, each rotating component 2 is sequentially hinged together by a hinge 24. Hinging them together by the hinge 24 improves the rotational flexibility of each rotating component 2.

[0052] Specifically, the hinge 24 includes two connecting pieces and a hinge shaft. Both connecting pieces are rotatably connected to the hinge shaft, and each connecting piece is fixedly connected to one of the two adjacent outer shells 221. The hinge 24 has a simple structure and a reasonable design.

[0053] In one embodiment, the telescopic component 14 includes a threaded cylinder 141 and threaded rods 142; there are two threaded rods 142, each corresponding to one end of the threaded cylinder 141; the two threaded rods 142 are respectively fixedly connected to two support blocks 13. The telescopic component 14 has a simple structure and is easy to manufacture and process.

[0054] Specifically, the threads at the two ends of the threaded cylinder 141 have opposite directions of rotation. When the threaded cylinder 141 is rotated, the two threaded rods 142 can move away from or towards each other.

[0055] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
