Description

Technical Field

[0001] This utility model relates to the field of wet wipe production technology, and in particular to a non-woven fabric impregnation device for a wet wipe production line. Background Technology

[0002] The production process of wet wipes involves a non-woven fabric humidification step. In this step, the non-woven fabric first enters a soaking device, where the soaking solution is sprayed evenly onto the fabric at a precise ratio and speed. This ensures that each piece of non-woven fabric fully absorbs the soaking solution, achieving the ideal humidity and liquid content. After soaking, the non-woven fabric passes through a roller device to further ensure the even distribution of the liquid and remove excess soaking solution, making the wet wipes more suitable for subsequent folding and cutting processes.

[0003] In existing soaking devices, soaking solution is sprayed onto the nonwoven fabric through multiple arranged spray nozzles, and excess soaking solution is recycled after seeping and dripping. However, this recycled soaking solution carries some fiber impurities from the nonwoven fabric, which affects the quality of the soaked product during recycling and reuse. Utility Model Content

The spraying mechanism includes a water pump, multiple spraying branch pipes arranged on the top of the impregnation chamber, multiple spraying heads disposed on the spraying branch pipes, a main spraying pipe connected to the multiple spraying branch pipes, and a connecting... A hose is provided between the water pump and the main spray pipe; a three-way valve is installed at the inlet end of the water pump; a first supply pipe is provided between one of the connectors of the three-way valve and the bottom of the raw material tank; a recovery tank for recovering the soaking solution is provided at the bottom of the soaking machine box; a second supply pipe is provided between the remaining connector of the three-way valve and the bottom of the recovery tank; a filter mechanism is provided on the top of the recovery tank to filter the soaking solution entering the recovery tank; a plug-in interface is provided on the front side of the soaking machine box; the filter mechanism is plugged into the plug-in interface and covers the top of the recovery tank; a sealing structure is provided at the connection between the filter mechanism and the plug-in interface.

[0006] A further feature of this invention is that the front side of the soaking chamber is provided with a receiving opening communicating with the plug-in interface; the filtering mechanism includes a plug-in frame inserted into the plug-in interface, a filter screen disposed within the plug-in frame, an end cap disposed at one end of the plug-in frame and located within the receiving opening, and a handle disposed on the end cap.

[0007] A further feature of this invention is that the sealing structure includes a first sealing ring disposed on the inner side of the end and pressed against the receiving opening, and a second sealing ring embedded on the periphery of the end cap and pressed against the inner side of the receiving opening.

[0008] A further feature of this invention is that: a lifting seat is provided at the end of the soaking chamber near the guide shaft; a support seat is provided on the soaking chamber below the lifting seat; a limiting shaft is provided on the support seat passing through the lifting seat; a compression spring is sleeved on the limiting shaft between the lifting seat and the support seat; an anti-loosening nut is threaded to the upper end of the limiting shaft; and the end of the guide shaft is rotatably connected to the lifting seat via a bearing.

[0009] A further feature of this invention is that a transparent observation window is provided on the front side of the soaking chamber, located above the recycling bin.

[0010] In summary, the beneficial effects of this utility model are:

[0011] 1. During the transport process, the nonwoven fabric passes through the nonwoven fabric impregnation device. The nonwoven fabric passes through multiple guide shafts in sequence. At this time, the spraying mechanism is turned on, and the water pump draws the impregnation liquid from the raw material tank. The liquid is then sprayed onto the nonwoven fabric through the main spray pipe, spray branches, and spray heads. Excess impregnation liquid drips down and is filtered by the filtration mechanism before being recycled back into the recycling tank. At the same time, the three-way valve is connected to the second liquid supply pipe, and the impregnation liquid in the recycling tank is drawn off by the water pump and sprayed onto the nonwoven fabric for recycling through the main spray pipe, spray branches, and spray heads. In addition, after the filtration mechanism has been used for a period of time, if a lot of fiber impurities adhere to the filtration mechanism, the filtration mechanism can be directly pulled out from the insertion interface for replacement or cleaning.

[0012] 2. The filter mechanism includes a plug-in frame that is inserted into the plug-in interface, a filter screen set in the plug-in frame, an end cap set at one end of the plug-in frame and located in the receiving port, and a handle set on the end cap. The filter screen can filter fibrous impurities, and the handle makes it easy to remove the filter mechanism for replacement or cleaning.

[0013] 3. The sealing structure includes a first sealing ring disposed on the inner side of the end and pressed against the receiving port, and a second sealing ring embedded on the periphery of the end cap and pressed against the inner side of the receiving port, thereby ensuring the sealing of the connection. After the second sealing ring is deformed, it can fix the end cap by friction, thereby preventing the filter mechanism from loosening.

[0014] 4. By setting up a lifting seat, support seat, limit shaft and compression spring, the lifting seat can be elastically raised and lowered, so that the nonwoven fabric can be adjusted in tightness during transportation by the elastic raising and lowering of the lifting seat when passing around the guide shaft.

A support seat 14 is provided on the soaking chamber 1 below the lifting seat 13. A limiting shaft 15 is provided on the support seat 14, passing through the lifting seat 13. A compression spring 16 is sleeved on the limiting shaft 15, located between the lifting seat 13 and the support seat 14. An anti-loosening nut 17 is threaded to the upper end of the limiting shaft 15. The end of the guide shaft 2 is rotatably connected to the lifting seat 13 through a bearing.

[0021] like Figure 1 and Figure 2As shown, the spraying mechanism includes a water pump 41, multiple spraying branch pipes 42 arranged on the top of the soaking chamber 1, multiple spraying heads 43 arranged on the spraying branch pipes 42, a spraying main pipe 44 connected to the multiple spraying branch pipes 42, a hose 45 connecting the water pump 41 and the spraying main pipe 44, and a three-way valve 46 arranged at the liquid inlet end of the water pump 41. A first liquid supply pipe 47 is arranged between one of the connectors of the three-way valve 46 and the bottom of the raw material tank 3.

[0022] like Figure 1 and Figure 2 As shown, a recovery tank 6 for recovering the soaking solution is provided at the bottom of the soaking chamber 1. A second liquid supply pipe 61 is provided between the remaining connector of the three-way valve 46 and the bottom of the recovery tank 6. A filter mechanism 7 is provided on the top of the recovery tank 6 to filter the soaking solution entering the recovery tank 6. A U-shaped plug-in interface 11 is provided on the front side of the soaking chamber 1, extending to the rear side of the soaking chamber 1. The filter mechanism 7 is plugged into the plug-in interface 11 and covers the top of the recovery tank 6. A sealing structure 8 is provided at the connection between the filter mechanism 7 and the plug-in interface 11.

[0023] like Figure 1 and Figure 2 As shown, the soaking chamber 1 has a receiving opening 12 communicating with the insertion interface 11 on its front side; the filtering mechanism 7 includes a plug frame 71 inserted into the insertion interface 11, a filter screen 72 disposed within the plug frame 71, an end cap 73 disposed at one end of the plug frame 71 and located within the receiving opening 12, and a handle 74 disposed on the end cap 73.

A transparent observation window 18 is also provided on the front side of the soaking chamber 1 above the recovery tank 6.

[0024] Implementation effect: During the transport process, the nonwoven fabric passes through the nonwoven fabric impregnation device and passes around multiple guide shafts 2 in sequence. At this time, the spraying mechanism is turned on, and the water pump 41 draws out the impregnation liquid in the raw material box 3 and sprays it onto the nonwoven fabric through the spray main pipe 44, spray branch pipes 42, and spray head 43. Excess impregnation liquid drips down and is filtered by the filter mechanism 7 and then recycled into the recycling box 6. At the same time, the three-way valve 46 is connected to the second liquid supply pipe 61, and the impregnation liquid in the recycling box 6 is drawn out by the water pump 41 and sprayed onto the nonwoven fabric for recycling through the spray main pipe 44, spray branch pipes 42, and spray head 43. In addition, after the filter mechanism 7 has been used for a period of time, when a lot of fiber impurities are attached to the filter mechanism 7, the filter mechanism 7 can be directly pulled out from the insertion interface 11 for replacement or cleaning.

[0025] The filter mechanism 7 includes a connector frame 71 inserted into the connector 11, a filter screen 72 disposed within the connector frame 71, an end cap 73 disposed at one end of the connector frame 71 and located within the receiving port 12, and a handle 74 disposed on the end cap 73.

The deformation of the second sealing ring 82 can also fix the end cap 73 through friction, preventing the filter mechanism 7 from loosening. By providing a lifting seat 13, a support seat 14, a limiting shaft 15, and a compression spring 16, the lifting seat 13 can be elastically raised and lowered. This allows the nonwoven fabric to adjust its tension during transport by elastically raising and lowering the lifting seat 13 as it passes around the guide shaft 2.
