A packaging device for sanitary napkin core material

Abstract

This utility model discloses a packaging device for sanitary napkin core material, including a pressing mechanism. Two pressing mechanisms are arranged sequentially along the material's forward direction. A first conveyor is located below each pressing mechanism. A longitudinal winding machine is positioned between the two pressing mechanisms, and a transverse winding machine is located on one side of each pressing mechanism. In this utility model, the material is conveyed forward along the first conveyor, and the pressing mechanisms compress the material. When the material reaches the longitudinal winding machine, the longitudinal winding machine packages the material longitudinally, wrapping it with a film in the longitudinal direction. As the material continues to advance, it enters the transverse winding machine, where it is transversely packaged, wrapping the material with a film in the transverse direction until the film completely covers the material. The material packaged with the film experiences more uniform stress, preventing deformation due to uneven stress. Simultaneously, it prevents the material from contacting the outside environment, thus preventing contamination.

Description

Technical Field

[0001] This utility model relates to the field of packaging device technology, and in particular to a packaging device for sanitary napkin core material. Background Technology

[0002] Sanitary napkins are hygiene products used by women during menstruation. Their main materials are cotton, non-woven fabric, pulp, or polymers and polymer composite paper made from these materials. The absorbent core in sanitary napkins is mostly made of cotton. After the core material is manufactured, it needs to be transported and packaged. Generally, a folding machine is used to stack the core material on a pallet, forming a cubic structure for easy packaging. Then, strapping is used to bind the core material, preventing it from unraveling. However, using strapping can cause stress concentration, leading to deformation of the core material. Furthermore, cutting the strapping during unpacking can release this stress, causing the strap to unravel rapidly and potentially injuring workers. Additionally, strapping does not completely seal the core material, allowing it to come into contact with the outside environment and become contaminated. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a packaging device for sanitary napkin core materials.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A packaging device for sanitary napkin core material includes a pressing mechanism, wherein two pressing mechanisms are provided and are arranged sequentially along the material's forward direction;

[0006] There are two first conveyors, each located below one of the two pressing mechanisms.

[0007] A longitudinal winding machine, located between the two clamping mechanisms, is used for longitudinal packaging of materials;

[0008] A transverse winding machine is installed on one side of the pressing mechanism and is used for transverse packaging of materials.

[0009] Preferably, the pressing mechanism includes a frame, on which a screw jack is mounted, and a pressing assembly is connected to the screw jack for pressing the material, and the first conveyor is located below the pressing assembly.

[0010] Preferably, the clamping assembly includes a connecting frame, which is connected to the screw jack, and a clamping frame is fixedly connected to the lower end of the connecting frame.

[0011] Preferably, the clamping frame is provided with a clamping belt.

[0012] Preferably, a guide rod is fixedly provided on the connecting frame, and the guide rod is slidably disposed on the frame.

[0013] Preferably, the longitudinal winding machine includes a fixed plate, which is vertically fixed between the two pressing mechanisms. The fixed plate has a connecting hole, and a rotating ring is rotatably mounted on the fixed plate. A first winding rod is fixedly mounted on the rotating ring.

[0014] Preferably, the transverse winding machine includes a base, a rotating disk rotatably mounted on the base, a first column fixedly mounted on the base, the first column being located on one side of the rotating disk, a movable frame vertically slidably mounted on the first column, and a second winding rod mounted on the movable frame.

[0015] Preferably, a second column is fixedly installed on the base, the second column is located on one side of the rotating disk, a clamping rod is vertically slidably installed on the second column, a clamping plate is installed on the clamping rod, and the clamping plate is located above the rotating disk.

[0016] Preferably, a lifting mechanism is provided between the pressing mechanism and the transverse winding machine, and a second conveyor is provided on one side of the lifting mechanism.

[0017] Preferably, the lifting mechanism includes a lifting frame, a lifting seat is vertically slidably mounted on the lifting frame, a clamping cylinder is fixedly mounted on the lifting seat, a fork support is fixedly mounted on the piston rod of the clamping cylinder, and the fork support is slidably mounted on the lifting seat.

[0018] The beneficial effects of adopting the above technical solution are as follows:

[0019] In this invention, the folded cotton core material is conveyed to the first conveyor. It is first compressed by one of the pressing mechanisms, compressing a portion of the material while the other portion is wrapped with film by a longitudinal winding machine. Then, the material is conveyed to a position below another pressing mechanism, where the compressed portion is further compressed. The longitudinal winding machine then wraps the other portion with film. Finally, the material is conveyed to a transverse winding machine for transverse film wrapping. Film wrapping ensures even stress distribution on the cotton core material, preventing deformation. Simultaneously, the film completely covers the material, effectively preventing contact with the outside environment and avoiding contamination. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1 As shown, a packaging device for sanitary napkin core material includes two pressing mechanisms 1 arranged sequentially along the material's forward direction. A first conveyor 2 is positioned below each pressing mechanism 1 for conveying the material. A longitudinal winding machine 3 is positioned between the two pressing mechanisms 1 for longitudinal packaging of the material. A transverse winding machine 4 is positioned on one side of each pressing mechanism 1 for transverse packaging of the material. In this invention, the core material is stacked on a tray after being stacked to form a cubic structure suitable for packaging. The core material is conveyed by one of the first conveyors 2 to the area below one of the pressing mechanisms 1, where it is pressed. During the pressing process, the first conveyor 2 simultaneously conveys material to one side of the longitudinal winding machine 3. As the material passes through the longitudinal winding machine 3, it is longitudinally wrapped, allowing the film to encapsulate the material. As the material continues to advance, when the packaged portion enters the other first conveyor 2, the other pressing mechanism 1 presses the material and continuously pushes it forward. The longitudinal winding machine 3 continues to wrap and pack the unpacked portion until the longitudinal portion is completely wrapped, so that the film completely covers the longitudinal portion of the material. Continuing to be conveyed by the first conveyor 2, the material enters the transverse winding machine 4, which wraps the material laterally, so that the film completely covers the transverse portion of the material, thus completing the packaging. The cotton core material wrapped with film experiences more even stress, preventing localized stress that could cause deformation. Simultaneously, the film completely covers and encloses the cotton core material, preventing it from directly contacting the outside environment and effectively avoiding contamination.

[0030] Furthermore, such as Figure 2 As shown, the pressing mechanism includes a frame 5, which is fixedly mounted on the ground. A screw jack 6 is mounted on the top of the frame 5, and a pressing assembly is connected to the screw jack 6. The pressing assembly can slide vertically on the frame 5 to press the material. The first conveyor 2 is located below the pressing assembly. There are two screw jacks 6, which are respectively connected to both sides of the pressing assembly to make the force on the pressing assembly more even. In this embodiment, when the material is conveyed by the first conveyor 2, the screw jack 6 drives the pressing assembly to slide downward. The pressing assembly squeezes the material downward to press it and prevent it from loosening. As the material is continuously conveyed, the longitudinal winding machine 3 longitudinally packages and winds the material.

[0031] It should be noted that a drive motor is fixedly installed on the frame 5, and the output end of the drive motor is connected to a dual-output shaft reducer. The two output shafts of the dual-output shaft reducer are respectively connected to two screw jacks 6, thereby driving the two screw jacks 6 to achieve synchronous transmission. In this embodiment, the screw jack 6 adopts a commercially available helical screw jack, so this equipment belongs to the prior art and will not be described in detail here.

[0032] Furthermore, the clamping assembly includes a connecting frame 7, which is rotatably connected to the screw of the screw jack 6. During rotation and lifting, the screw of the screw jack 6 can drive the connecting frame 7 to rise and fall. A clamping frame 8 is fixedly connected to the lower end of the connecting frame 7. A clamping belt 9 is mounted on the clamping frame 8 and can rotate on it. In this embodiment, when the material passes under the first conveyor 2 below the clamping assembly, the clamping assembly moves downward under the drive of the screw jack 6 until the material is clamped. The clamping belt 9 directly contacts the top of the material. During the material conveying process by the first conveyor 2, since the clamping belt 9 is rotatably mounted on the clamping frame 8, it can rotate synchronously with the movement of the material, avoiding obstruction to the material's movement.

[0033] It should be noted that multiple pressing rollers are horizontally arranged on the pressing frame 8. The pressing rollers are rotatably mounted on the pressing frame 8, and the pressing belt 9 is wound around the pressing rollers. Therefore, the material can be conveyed forward during the pressing process.

[0034] Furthermore, multiple guide rods 10 are fixedly installed on the connecting frame 7. The guide rods 10 are vertically installed and slidably installed on the frame 5. During the up-and-down sliding process of the connecting frame 7, the guide rods 10 can play a guiding role and prevent the connecting frame 7 from deflecting.

[0035] Furthermore, a fixed rod 28 is fixedly installed on the frame 5, and a proximity sensor is installed on the fixed rod 28. As the upper end of the rising guide rod 10 of the connecting frame 7 rises synchronously, when the proximity sensor detects the guide rod 10, it controls the screw jack 6 to stop working, preventing the connecting frame 7 from continuing to rise, thus playing a limiting role.

[0036] Furthermore, such as Figure 3As shown, the longitudinal winding machine 3 includes a fixed plate 11, which is vertically fixed between two pressing mechanisms 1. A circular connecting hole is provided in the middle of the fixed plate 11. A rotating ring 12 is rotatably mounted on the fixed plate 11, and the rotating ring 12 is coaxially arranged with the connecting hole on the fixed plate 11. A first winding rod 13 is fixedly mounted on the rotating ring 12. In this embodiment, the film roll for packaging is sleeved on the first winding rod 13, and one end of the film is pulled out and fixed to one side of the material. As the first conveyor 2 conveys the material, the material moves forward and passes through the connecting hole on the fixed plate 11. At the same time, the rotating ring 12 rotates, driving the first winding rod 13 to rotate, so that the film is continuously wrapped around the material, thus wrapping and packaging the material until the longitudinal part of the material is completely covered by the film.

[0037] It should be noted that a motor 31 is fixedly mounted on the fixed plate 11, and a drive wheel 32 is fixedly mounted on the output shaft of the motor 31. A tension wheel 29 is also rotatably mounted on the fixed plate 11. A transmission belt 30 is wound around the outer surface of the drive wheel 32, the tension wheel 29, and the rotating ring 12. After the motor 31 starts, it drives the transmission belt 30 to rotate. The transmission belt 30 can drive the rotating ring 12 to rotate on the fixed plate 11, so that the film can be wound on the material. The tension wheel 29 can tighten the transmission belt 30 to prevent the transmission belt 30 from loosening.

[0038] Furthermore, multiple limiting wheels 33 are rotatably mounted on the fixed plate 11, and a limiting ring is fixedly mounted on one side of the rotating ring 12. The diameter of the limiting ring is larger than the diameter of the rotating ring 12. The limiting wheels 33 roll in contact with the outer surface of the limiting ring, thereby limiting the rotating ring 12 and enabling the rotating ring 12 to rotate in a vertical state.

[0039] Furthermore, such as Figure 5 As shown, the horizontal winding machine 4 includes a base 14, which is fixedly mounted on the ground. A rotating disk 15 is rotatably mounted on the base 14, rotating horizontally on the base 14. A first column 16 is fixedly mounted on the base 14, located on one side of the rotating disk 15. A movable frame 17 is vertically slidably mounted on the first column 16, and a second winding rod 18 is vertically mounted on the movable frame 17. In this embodiment, after the material is packaged by the longitudinal winding machine 3, it is conveyed by the first conveyor 2 to the rotating disk 15. A film roll is sleeved on the second winding rod 18. One end of the film roll is pulled out and fixed to the side of the material. As the rotating disk 15 rotates, the film wraps around the material. As the movable frame 17 slides upward along the first column 16, the film gradually and completely wraps the side of the material, thus completing the packaging.

[0040] In one embodiment, a motor is fixedly mounted on the base 14, the output shaft of the motor is vertically arranged, the output shaft of the motor is fixedly connected to the rotating disk 15, the output shaft of the motor and the rotating disk 15 are coaxially arranged, and the motor drives the rotating disk 15 to rotate on the base 14.

[0041] It should be noted that a lead screw is vertically rotatably mounted on the first column 16, and a lead screw nut is mounted on the movable frame 17. The lead screw nut is threadedly connected to the lead screw. When the lead screw on the first column 16 rotates, it can drive the movable frame 17 to slide vertically along the first column 16.

[0042] Furthermore, multiple conveying rollers are rotatably mounted on the rotating disk 15. After the material is conveyed onto the rotating disk 15, the conveying rollers rotate to transport the material to the center of the rotating disk 15, thereby facilitating the rotation, packaging, and winding of the material.

[0043] Furthermore, a second column 19 is fixedly mounted on the base 14, located on one side of the rotating disk 15. A pressing rod 20 is vertically slidably mounted on the second column 19, and a pressing plate 21 is rotatably mounted on the pressing rod 20, located above the rotating disk 15. In this embodiment, when the material is conveyed onto the rotating disk 15, the pressing rod 20 slides downward along the second column 19, causing the pressing plate 21 to apply downward pressure to the material, compressing it and preventing it from loosening. Subsequently, the material is horizontally wrapped and packaged, so that the film completely encapsulates the material.

[0044] It should be noted that two sprockets are rotatably mounted on the second column 19. The two sprockets are arranged vertically and a chain is wound around them. The clamping rod 20 is fixedly connected to the chain. During the rotation of the sprockets, the chain can be driven to rotate, and the chain drives the clamping rod 20 to slide in the vertical direction, thereby clamping the material.

[0045] Furthermore, such as Figure 1 and Figure 4 As shown, a lifting mechanism 22 is provided between the pressing mechanism 1 and the transverse winding machine 4, and a second conveyor 23 is provided on one side of the lifting mechanism 22. In this embodiment, the lifting mechanism 22 can lift and stack the materials for longitudinally winding the film, so that multiple materials are stacked together, which facilitates the transverse wrapping and wrapping of multiple materials together. Specifically, the materials after longitudinal wrapping are conveyed by the first conveyor 2 and then enter the second conveyor 23. Subsequently, the lifting mechanism 22 lifts the materials on the second conveyor 23, so that the next material that has been longitudinally wrapped is conveyed to the second conveyor 23. The lifting mechanism 22 stacks the lifted materials on the materials located on the second conveyor 23, and then conveys the stacked materials together to the transverse winding machine 4 for transverse wrapping and packaging.

[0046] Furthermore, such as Figure 4As shown, the lifting mechanism 22 includes a lifting frame 24, which is fixedly mounted on the ground and located on one side of the second conveyor 23. A lifting seat 25 is vertically slidably mounted on the lifting frame 24, and two clamping cylinders 26 are fixedly mounted on the lifting seat 25. The piston rod of the clamping cylinder 26 is fixedly mounted with a fork support 27, which is slidably mounted on the lifting seat 25. When the piston rods of the two clamping cylinders 26 extend or retract, they can drive the two fork supports 27 to move closer to or further away from each other. The material moves in the direction of the material. In this embodiment, the fork support 27 is initially located at the lower part of the second conveyor 23. When the material is conveyed to the second conveyor 23, the two clamping cylinders 26 drive the two fork supports 27 to move towards each other, so that the fork supports 27 are inserted into the bottom of the material. Then the lifting seat 25 slides upward on the lifting frame 24 to lift the material. When the next material is conveyed to the second conveyor 23, the clamping cylinder 26 drives the two fork supports 27 to move away from each other, so that the material can be stacked together.

[0047] It should be noted that two sets of sprockets are rotatably installed on the lifting frame 24, with two sprockets in each set. The two sprockets in each set are vertically mounted on the lifting frame 24, and a chain is wound around each of the two sprockets in each set. The lifting seat 25 is fixedly connected to the chain. The chain rotates as the sprockets rotate on the lifting frame 24, thereby causing the lifting seat 25 to slide vertically on the lifting frame 24.

[0048] Furthermore, a slide bar is fixedly installed on the lifting frame 24, and the slide bar is set in the vertical direction. A slide seat is fixedly installed on the lifting seat 25, and the slide seat is slidably connected to the slide bar, thereby making the sliding of the lifting seat 25 more stable.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
