DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0019] Please refer to Figure 1-6 The present embodiment provides a packaging device for wet wipes, including a packaging mechanism, the packaging mechanism including a shaping component, a sealing component and a cutting component sequentially installed on a frame 100 along a first direction, for wrapping a packaging film on the wet wipes to form bagged wet wipes; a detection mechanism, the detection mechanism including a transfer box 200 fixedly installed on the frame 100 and a mechanical arm movably installed on the frame 100; the bottom of the transfer box 200 is provided with evenly arranged small suction cups 210, one side of which is connected to the cutting component through a transmission component; the small suction cups 210 are connected to the transfer box 200 through a tension sensor; the mechanical arm is linked to the tension sensor to detect the transfer box 200; The extracted bagged wet wipes are placed in categories; the conveying assembly includes two conveying shafts arranged along the first direction and a nozzle 220 located between the two conveying shafts; the two conveying shafts are respectively a horizontally arranged first conveying shaft 221 and an inclinedly arranged second conveying shaft 222; the first conveying shaft 221 is located at one end close to the cutting assembly, and is connected to the second conveying shaft 222 through a conveying belt 223; the number of the conveying belts 223 includes two, which are respectively located at both ends of the first conveying shaft 221; the second conveying shaft 222 is located at one end close to the transfer box 200, and the height of the side close to the transfer box 200 is relatively low.

[0020] In this embodiment, the packaging mechanism includes a shaping component, a sealing component and a cutting component; wherein the shaping component is U-shaped and is used to fold the flat packaging film into a U-shape, so that the two edges of the packaging film are kneaded and hot-melted through the sealing component to form a cylindrical structure; while the packaging film is being hot-melted by the sealing component, the front-end device will also put the wet wipes onto the packaging film at a uniform speed in advance, so that the wet wipes are packaged during the hot-melting process; finally, the kneaded packaging film is cut at equal distances through the cutting component to form independently packaged bagged wet wipes.

[0021] In this embodiment, the detection mechanism is connected to the cutting assembly via a transmission assembly, and is used to perform empty bag detection and seal detection on the cut bagged wet wipes.

[0022] In this embodiment, the first conveying shaft 221 is horizontally arranged and located at one end close to the cutting assembly; the second conveying shaft 222 is tilted and located at one end close to the transfer box 200, and the height of the side close to the transfer box 200 is relatively low; the first conveying shaft 221 and the second conveying shaft 222 are connected by two conveying belts 223 with relatively small widths, and the two sides of the independently packaged bagged wet wipes are respectively placed on the two conveying belts 223, and the two conveying belts 223 can not only support and convey the bagged wet wipes, but also adapt to the relatively tilted use environment of the second conveying shaft 222, so that in the process of driving the bagged wet wipes, the angle of the bagged wet wipes can be effectively changed to make it tilted toward the side close to the transfer box 200; finally, it can be separated from the conveying assembly through the jet drive of the nozzle 220; when the bagged wet wipes are normally filled with wet wipes, they will be turned over to the transfer box 200; when there are no wet wipes inside the bagged wet wipes, they are convenient to be blown directly to the side of the transfer box 200 away from the conveying assembly due to the lighter gravity, thereby completing the detection of empty packages.

[0023] In this embodiment, since the bagged wet wipes enter the transfer box 200 after being turned over, the side that is kneaded and hot-melted will face downward; when the robotic arm absorbs and extracts the top of the wet wipes, the four corners of the bottom and the two sides in the middle are respectively adsorbed and connected to the small suction cups 210; if all the seals are in a normal state, the tension sensor connected to the small suction cup 210 will detect the synchronous tension; conversely, if some of the seals are abnormal, the corresponding tension sensor will detect the tension with a delay; finally, if all the seals are abnormal, the corresponding tension sensor will detect the tension one after another due to the different times when the small suction cup 210 is separated from the packaging film, thereby determining that the seal is abnormal.

[0024] In this embodiment, the adsorption force of the robotic arm on the bagged wet wipes is relatively greater than the adsorption force of the small suction cup 210 on the bagged wet wipes; at the same time, the adsorption forces of both are smaller than the external force required to destroy the bagged wet wipes. Therefore, by applying reverse force to the bagged wet wipes by the robotic arm and the small suction cup 210, the seal can be inspected without destroying it.

[0025] In this embodiment, the robotic arm is linked with the tension sensor. If all the tension sensors synchronously detect the force, the robotic arm will place the bagged wet wipes in the qualified product area, otherwise it will place the bagged wet wipes in the unqualified area.

[0026] In a preferred embodiment, a support plate 224 is further provided between the first conveying shaft 221 and the second conveying shaft 222; the support plate 224 is located on a side relatively close to the transfer box 200, and its extension direction is parallel to the conveying direction of the adjacent belt 223, and is used to support the side of the bagged wet wipes.

[0027] In this embodiment, the support plate 224 is fixedly mounted on the frame 100, and its extension direction is parallel to the extension direction of the conveying assembly. When the bagged wet wipes begin to tilt, the support plate 224 will support its bottom to prevent it from escaping from the conveying assembly.

[0028] In this embodiment, the height of the support plate 224 is relatively lower than the thickness of the bagged wet wipes, thereby ensuring that the bagged wet wipes can be turned over to the other side of the support plate 224 .
