Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, specifically a folding mechanism for wet wipe production. Background Technology

[0002] Wet wipes are moistened tissues used to wipe the skin. Wet wipes on the market can be broadly divided into two categories: one type is sterilized itself but cannot disinfect other items; it contains skin-care ingredients and is only for moisturizing the skin. The other type is disinfecting wipes, which are not only sterilized themselves but also disinfect other items; they can be used to disinfect or sterilize skin abrasions, scratches, etc.

[0003] Typically, wet wipes are folded by pushing a pusher plate. However, after folding, the surface of the wet wipes is relatively loose due to inertia. Therefore, existing technologies use a flattening structure to flatten the wet wipes after folding. For example, the automatic wet wipe folding device for a wet wipe production line disclosed in utility model CN220375946U uses a motor, a threaded shaft, and a pressure plate to press the folded wet wipes together, thereby flattening them and improving the folding quality.

[0004] However, existing technologies still have some shortcomings. For example, due to the influence of equipment and environmental factors during the stacking process, the looseness of different wet wipe stacks varies, while the leveling range of the leveling equipment is the same, resulting in different degrees of compression between different wet wipe stacks. When a wet wipe stack is excessively compressed, the liquid in the upper layer of wet wipes is squeezed out and seeps into the lower layer. This not only leads to different moisture levels in the wet wipes, affecting product quality, but also causes water to be squeezed out when the moisture content of the bottom wet wipes is too high, thus reducing the overall moisture content of the wet wipe stack. Therefore, we propose a folding mechanism for wet wipe production. Utility Model Content

[0026] 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.

[0027] Example 1

[0028] A folding mechanism for producing wet wipes, such as Figures 1-5 As shown, it includes an outer shell 1; the outer shell 1 is provided with a flattening mechanism 2, which can flatten the folded wet wipes, thereby reducing wrinkles or creases on the surface of the wet wipes.

[0029] Specifically, the leveling mechanism 2 includes a support plate 21, which is connected to the middle of the inner shell 1. The support plate 21 can support and place folded wet wipes, thus facilitating the leveling of the wet wipes. A baffle 22 is connected to the top of the support plate 21. The baffle 22 has a ring structure and is arranged around the outside of the support plate 21. The baffle 22 is slidably connected to the inner top of the baffle 22, and the baffle 22 is movably connected to the support plate 21. A flat plate 23 is slidably connected to the inner top of the baffle 22. The flat plate 23 can press and level the folded wet wipes. The flat plate 23 has a hollow structure. A guide tube 24 is fixedly connected to the top of the flat plate 23. The top of the guide tube 24 passes through the baffle 22 and connects to the inside of the baffle 22. The structure of the guide tube 24 can connect the hollow flat plate 23 and the inside of the baffle 22. An air inlet pipe 29 is fixedly connected to the top of the flat plate 23. The air inlet pipe 29 is interconnected with the interior of the flat plate 23. An external air intake device can be connected to the end of the air inlet pipe 29, so that air can be continuously pumped into the interior of the flat plate 23. A drive structure is connected to the top of the air inlet pipe 29.

[0030] Furthermore, both the support plate 21 and the baffle 22 are hollow structures. The guide tube 24 is internally connected to the baffle 22. Corresponding connecting holes 25 are provided on the sides of the support plate 21 and the baffle 22. The connecting holes 25 allow the hollow support plate 21 and the baffle 22 to communicate with each other, thus facilitating the guidance of the gas pumped into the air inlet pipe 29. An exhaust hole 26 is provided at the top of the support plate 21. The exhaust holes 26 are evenly distributed at the top of the support plate 21, allowing the pumped gas to be discharged. The airflow blows the liquid generated during the leveling process upwards, preventing excessive liquid accumulation at the bottom of the wet wipe and thus avoiding seepage that affects the moisture content of the wet wipe. The support plate 21 has a platform-like structure, and the bottom structure of the baffle 22 corresponds to the structure of the support plate 21. The edges of the platform-like support plate 21 are inclined, allowing it to cooperate with the inner bottom of the baffle 22, thus positioning the support plate 21 using the baffle 22.

[0031] It is worth noting that a sleeve 27 is fixedly connected to the top of the baffle 22, and a guide tube 24 is slidably connected inside the sleeve 27. The structure of the sleeve 27 can seal the guide tube 24, thereby reducing the thickness of the top of the baffle 22. An exhaust port 28 is provided on the side of the guide tube 24. The structure of the exhaust port 28 can control the height of the entire plate 23, so that the entire plate 23 can communicate with the interior of the baffle 22 after it descends to the set height.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on Embodiment 1, the outer shell 1 is provided with a reflux mechanism 5. The reflux mechanism 5 can conveniently reflux the moisture inside the high humidity gas, thereby further reducing the loss of moisture content inside the wet wipe.

[0034] In this embodiment, the backflow mechanism 5 includes an exhaust pipe 51 fixedly connected inside the leveling plate 23, and the exhaust pipe 51 is structured to discharge the exhaust gas. The exhaust pipe 51 is fixedly connected with a recovery cover 52 at the end, and the recovery cover 52 is fixedly connected at the bottom end of the leveling plate 23. The inside of the recovery cover 52 is fixedly connected with a spacing net 53, and the recovery cover 52 is structured to guide the gas flow, and the spacing net 53 is structured to contact the top wet wipes and realize the leveling operation, and the porous structure of the spacing net 53 can facilitate the gas to pass through.

[0035] On this basis, one end of the exhaust pipe 51 passes through the air inlet pipe 29, and the other end of the exhaust pipe 51 passes through the leveling plate 23, and the top end of the exhaust pipe 51 is movably connected with a water absorption block 54 made of sponge or water absorption cotton. The water absorption block 54 is arranged through the air inlet pipe 29 and the exhaust pipe 51 respectively, so as to recover the water vapor in the exhaust gas and humidify the air inlet, thereby avoiding the excessive loss of water. The inside of the exhaust pipe 51 is fixedly connected with a supporting ring 55, and the supporting ring 55 is provided with a water leakage hole. The supporting ring 55 is structured to support the water absorption block 54, and the water leakage hole is structured to facilitate the exhaust gas to pass through the side surface of the water absorption block 54.

[0036] In addition, the inside of the shell 1 is connected with a conveying belt device 3 at the bottom end, and the supporting plate 21 is fixedly connected on the conveying belt device 3. One end of the shell 1 is provided with a discharge port 4, and the conveying belt device 3 can drive the supporting plate 21.

[0037] When the folding mechanism for wet paper towel production of the utility model is used, the supporting plate 21 is driven by the conveying belt device 3 to move to the lower side of the folding equipment and moves the folded wet wipes to the baffle 22. Then the air inlet pipe 29 moves downward under the drive of the driving structure, and the leveling plate 23 at the end of the air inlet pipe 29 moves synchronously, and the outer baffle 22 moves downward synchronously under the action of gravity. When the bottom of the baffle 22 contacts the edge of the supporting plate 21, the baffle 22 is limited by the supporting plate 21 and stops moving, and the supporting plate 21 is connected with the inside of the baffle 22 through the communication hole 25. Then the continuously moving air inlet pipe 29 drives the leveling plate 23 and the recovery cover 52 to move downward, and when the spacing net 53 contacts the top wet wipes, the communication hole 25 at the side of the guide pipe 24 moves to the cavity of the baffle 22. The gas pumped into the air inlet pipe 29 by the pump equipment flows through the baffle 22 and the supporting plate 21 and is discharged from the exhaust hole 26. In the process of extruding and leveling the wet wipes by the spacing net 53, the water is blown upward by the airflow, so as to balance the water content in the wet wipes to a certain extent. The exhaust gas flows from the recovery cover 52 to the exhaust pipe 51 after passing through the wet wipes and is finally discharged. After the leveling operation is completed, the baffle 22 and the leveling plate 23 are driven to rise and reset by the driving structure.
