Description

Technical Field

[0001] This utility model relates to the field of wet wipe wrapping and capping technology, specifically a wet wipe wrapping and capping device. Background Technology

[0002] Wet wipes can be broadly categorized into bagged wet wipes and boxed wet wipes based on their packaging. Boxed wet wipes consist of a wipe bag and a top cover, with the top cover glued to the bag. The top cover can be opened and closed for easy access to the wipes. In the production process of bagged wet wipes, an opening is made on the top surface of the bag to facilitate the user's extraction of the wipes, and a cap is affixed to the opening.

[0003] Currently, the sealing of wet wipes is done manually or by fully automated sealing machines. Manual operation is inefficient, while existing fully automated sealing machines require the precise coordination of multiple robotic arms to achieve sealing. These machines have complex structures, simple functions, and complex control systems, making them difficult to maintain and significantly increasing production costs. Therefore, we propose a wet wipe sealing device. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a wet wipe wrapping and capping device, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wet wipe pack capping device includes a base and a first conveyor belt for conveying wet wipe packs disposed on the base. A lifting frame is fixedly connected to the base, and a second conveyor belt for conveying caps is disposed on the lifting frame. An adhesive application mechanism and a cap removal mechanism are respectively disposed on the lifting frame.

[0007] Furthermore, the cap removal mechanism includes a first bracket and a movable plate. The bottom end of the first bracket is fixedly connected to the lifting frame. A drive arm and a limiting arm are rotatably connected to the first bracket. The drive arm and the limiting arm are of the same length, and the ends of the drive arm and the limiting arm away from the first bracket are rotatably connected to the movable plate. A negative pressure suction cup is provided on the movable plate.

[0008] Furthermore, a drive motor is fixedly mounted on the first bracket, and the output end of the drive motor is connected to one end of the drive arm.

[0009] Furthermore, an electric push rod is fixedly installed on the movable plate, with the output end of the electric push rod facing downward and connected to the negative pressure suction cup.

[0010] Furthermore, the glue application mechanism includes a second support, the bottom end of which is fixedly connected to the lifting frame, and one end of the second support is provided with a housing for holding glue. A glue application roller is rotatably connected to the inner wall of the housing, and the outer periphery of the glue application roller penetrates through the top of the housing.

[0011] Furthermore, a frame is fixedly connected to the end of the second bracket away from the lifting frame, and a sliding plate is slidably connected to the inner wall of the frame. One side of the sliding plate is fixedly connected to the surface of the housing, and one end of the sliding plate is elastically connected to the inner wall of the frame through a spring.

[0012] Furthermore, both sides of the housing are provided with inclined surfaces.

[0013] By employing the above technical solution, this utility model provides a wet wipe wrapping capping device. It possesses at least the following beneficial effects:

[0014] (1) The wet wipe pack capping device uses a lifting frame to install the second conveyor belt for conveying the cap directly above the first conveyor belt for conveying the wet wipe pack. This makes it easy for the cap-taking mechanism to transfer the cap from the second conveyor belt to the top of the first conveyor belt for capping. It can achieve automated and efficient capping without complicated motion trajectories. The structure is simple and practical, and it does not require a complicated control system or robotic arm to cooperate with, which can effectively reduce production costs.

[0015] (2) The wet wipe packing and capping device has an adhesive applicator set up near the running trajectory of the cap picking mechanism, and controls the height of the adhesive applicator roller by a spring so that after the cap picking mechanism picks up the cap, the adhesive applicator can automatically adhere to the bottom of the cap and adapt to the height change when the cap moves, thereby realizing automatic adhesive application and achieving automatic adhesive application and capping integration.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides a technical solution as follows:

[0026] A wet wipe pack capping device includes a base 1 and a first conveyor belt 2 mounted on the base 1. The first conveyor belt 2 is used to transport wet wipe packs. A lifting frame 3 is fixedly connected to the base 1, and a second conveyor belt 4 is mounted on the lifting frame 3. The second conveyor belt 4 is used to transport caps. There are two lifting frames 3, which are symmetrically arranged on both sides of the second conveyor belt 4 to improve the stability of the second conveyor belt 4. An adhesive application mechanism 5 and a cap-removing mechanism 6 are respectively mounted on the lifting frame 3. During operation, the cap-removing mechanism 6 picks up the caps from the second conveyor belt 4, moves them above the adhesive application mechanism 5 for adhesive application, and then transfers them to the wet wipe packs on the first conveyor belt 2 for capping. The capped wet wipe packs are then transported to the next stage by the first conveyor belt 2.

[0027] Specifically, the cap-removing mechanism 6 includes two symmetrically arranged first supports 601, the bottom ends of which are fixedly connected to the lifting frame 3. A drive motor 602 is fixedly mounted on one of the first supports 601. A drive arm 603 is connected to the output end of the drive motor 602. A movable plate 604 is rotatably connected to the end of the drive arm 603 away from the first support 601. An electric push rod 605 is fixedly mounted on the movable plate 604. The output end of the electric push rod 605 faces downward and is connected to a negative pressure suction cup 606. The negative pressure suction cup 606 can adsorb the cap of the wet wipe package. When the drive motor 602 is started, it can drive the drive arm 603 to rotate, which in turn drives the electric push rod 605 and the negative pressure suction cup 606 to move through the movable plate 604, thereby realizing the transfer of the cap.

[0028] Since the lids on the second conveyor belt 4 and the wet wipe packs on the first conveyor belt 2 are placed horizontally, the negative pressure suction cup 606 should remain facing downwards during suction. Therefore, a limiting arm 607 is rotatably connected to the first support 601. The ends of the drive arm 603 and the limiting arm 607 away from the first support 601 are rotatably connected to the moving plate 604. The limiting arm 607 and the drive arm 603 are the same length. From the front view, the limiting arm 607 and the drive arm 603 are parallel. From the top view, the limiting arm 607 and the drive arm 603 are offset from each other to avoid motion interference during rotation. Through the cooperation of the limiting arm 607 and the drive arm 603, the moving plate 604 can be limited. During the rotation of the drive arm 603, the drive arm 603, the limiting arm 607, the moving plate 604, and the horizontal part of the first support 601 always maintain a parallelogram state, thus ensuring that the negative pressure suction cup 606 always faces downwards, facilitating the picking up and pasting of the lids.

[0029] In this embodiment, the glue application mechanism 5 includes two symmetrically arranged second supports 501. The bottom ends of both second supports 501 are fixedly connected to the lifting frame 3 to support the glue application mechanism 5. One end of each second support 501 is provided with a housing 504 for holding glue. The housing 504 is hollow inside and has an injection port (not shown in the figure) for injecting glue into it. A glue application roller 505 is rotatably connected to the inner wall of the housing 504. The outer periphery of the glue application roller 505 penetrates the top of the housing 504 and extends to the outside of the housing 504. Most of the glue application roller 505 is immersed in glue. When the bottom of the lid moves on the surface of the glue application roller 505, the glue application roller 505 will rotate due to friction, thereby applying glue to the bottom of the lid.

[0030] To prevent the cap-removing mechanism 6 from colliding with the housing 504 during operation, a frame 502 is fixedly connected to the end of each of the two second supports 501 away from the lifting frame 3. A sliding plate 503 is slidably connected to the inner wall of the frame 502. One side of the sliding plate 503 is fixedly connected to the surface of the housing 504, allowing the housing 504 to move up and down relative to the second supports 501. The bottom end of the sliding plate 503 is elastically connected to the inner wall of the frame 502 through a spring 506. The spring 506 supports the sliding plate 503, ensuring that the sliding plate 503 always maintains a certain height. This allows the glue-applying roller 505 to adapt to the height changes of the cap during movement when the cap-removing mechanism 6 and the cap move above the glue-applying roller 505, always maintaining contact with the bottom of the cap and ensuring uniform glue application. In addition, both sides of the housing 504 are provided with inclined surfaces, making the housing 504 trapezoidal. The inclined surfaces can change the direction of motion transmission, so that if the lid-removing mechanism 6 or the lid comes into contact with the sides of the housing 504 during operation, the inclined surfaces can push the housing 504, causing the housing 504 to move up and down, thereby avoiding motion interference.

[0031] In use, the wet wipe pack sealing device of this utility model transports wet wipe packs via a first conveyor belt 2 and a second conveyor belt 4. During the sealing process, a drive motor 602 is activated, and its output drives a drive arm 603 to rotate. One end of the drive arm 603 drives a moving plate 604 to move around a circular trajectory. The moving plate 604 simultaneously drives an electric push rod 605 and a negative pressure suction cup 606. During its movement, the moving plate 604 drives a limiting arm 607 to rotate. Throughout this process, the limiting arm 607 remains parallel to the drive arm 603. The drive arm 603, the limiting arm 607, the moving plate 604, and the horizontal portion of the first support 601 maintain a parallelogram shape, ensuring that the negative pressure suction cup 606 always faces downwards. When the negative pressure suction cup 606 moves above the lid, the electric push rod 605 is activated, and its output moves downwards, driving the negative pressure suction cup 606 downwards. The negative pressure suction cup 606 then uses negative pressure to pick up the lid. Subsequently, the drive motor 602 is reversed, causing the cap-removing mechanism 6 to reset and move the cap. When the cap moves above the glue-applying mechanism 5, the glue-applying roller 505 remains in contact with the bottom of the cap under the elastic force of the spring 506. During the movement of the cap, the glue-applying roller 505 rotates due to friction, thus applying glue to the bottom of the cap. Then, the cap-removing mechanism 6 continues to operate and moves the cap above the wet wipes pack. At this time, the drive motor 602 stops running and the electric push rod 605 is activated. The output end of the electric push rod 605 moves downward, driving the negative pressure suction cup 606 downward to stick the glued cap onto the wet wipes pack.
