With the formation of people's hygienic habits and the improvement of living quality, wet wipes have become a necessity in people's daily life. During the processing of wet wipes, they are then sent into a spraying chamber for spraying treatment, so that the wet wipe liquid is sprayed onto the wet wipes, thereby making the wet wipe liquid carried on the non-woven fabric. This operation requires the use of a liquid adding device;

[0003] For example, the patent network discloses a double-sided liquid adding device in the production of wet wipes (publication number: CN217550130U). A plurality of spray heads are arranged on one infusion tube of this device so as to cover the non-woven fabric. However, the spraying range is adapted to the number of spray heads. If the width of the non-woven fabric is small, some spray heads will be outside the non-woven fabric, and the liquid sprayed by these spray heads will not be sprayed onto the non-woven fabric but will be sprayed into the air, and a part of the liquid sprayed into the air will vaporize, resulting in waste. Therefore, those skilled in the art have proposed a non-leakage quantitative liquid adding device for wet wipes. Content of the Utility Model

It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure.

[0034] Figure 6 It is a sectional view of a liquid adding mechanism of a non-leakage quantitative liquid adding device for wet wipes;

[0035] As Figures 1-6 shown, a non-leakage quantitative liquid adding device for wet wipes of the present disclosure may include components such as a conveying mechanism, a liquid adding mechanism, and a squeezing mechanism;

[0036] As Figures 1-6 shown, the conveying mechanism includes a liquid adding tank 1, an inlet 18, an outlet 19, a motor 20, a conveying roller 21, a threaded cylinder 22, and a secondary roller 27;

[0037] The inlet 18 is opened on the side surface of the liquid adding tank 1, the outlet 19 is opened on the other side surface of the liquid adding tank 1 and is aligned with the inlet 18. Two conveying rollers 21 are installed on the rear surface of the liquid adding tank 1 and are respectively on one side of the inlet 18 and the outlet 19. Each conveying roller 21 is installed at the driving end of the corresponding motor 20 extending into the liquid adding tank 1 and the end is rotatably connected to the inner wall of the liquid adding tank 1. Each secondary roller 27 is rotatably installed between the inner walls of the liquid adding tank 1 and is on one side of the corresponding conveying roller 21;

[0038] During use, the non-woven fabric is inserted into the liquid adding tank 1 through the inlet 18, bypasses the adjacent secondary roller 27 and conveying roller 21 from below, then bypasses the other conveying roller 21 and secondary roller 27 and exits from the outlet 19. Then the two motors 20 operate to drive the two conveying rollers 21 to rotate, and the rotating conveying rollers 21 make the bypassed non-woven fabric advance in the liquid adding tank 1;

[0039] As shown Figures 1-6 in the figure, the liquid adding mechanism includes a horizontal pipe 2, a liquid spraying head 3, a multi-way pipe 4, a piston 5, an extension rod 6, a mounting plate 7, a moving seat 8, a moving groove 9, a bidirectional screw 10, a threaded seat 11, an L-shaped plate 12, a first bevel gear 13, a second bevel gear 14, a first knob 15, a bracket 16, and a limiting plate 17;

[0040] The moving seat 8 is installed at the center of the upper surface of the liquid adding tank 1. The moving groove 9 is opened on the upper surface of the moving seat 8. The bidirectional screw 10 is rotatably installed between the inner walls of the moving groove 9. Two threaded seats 11 are respectively arranged on two threads of the bidirectional screw 10. The first bevel gear 13 is installed on the surface of the bidirectional screw 10 and is between the two threaded seats 11. The second bevel gear 14 is rotatably installed on the inner wall of the moving groove 9 and meshes with the first bevel gear 13. The first knob 15 is installed at the end of the second bevel gear 14 extending outside the moving seat 8. Two groups of horizontal pipes 2 are installed between the inner walls of the liquid adding tank 1 in an up-and-down distribution. Each group of liquid spraying heads 3 is evenly installed on the side of the corresponding horizontal pipe 2. Each multi-way pipe 4 is installed on the side of the corresponding group of all multi-way pipes 4 and the end extends outside the liquid adding tank 1. Two pistons 5 in each group are slidably arranged inside the corresponding horizontal pipe 2. Each extension rod 6 is installed at the center of the side of the corresponding piston 5 and extends outside the liquid adding tank 1. Each mounting plate 7 is installed at the end of all extension rods 6 on the same side. Each L-shaped plate 12 is installed on the upper surface of the corresponding threaded seat 11 and is fixedly connected to the mounting plate 7 on the same side. Two brackets 16 in each group are installed on the side of the corresponding mounting plate 7. Each limiting plate 17 is installed at the end of the corresponding group of brackets 16 extending into the liquid adding tank 1 and is above the conveying roller 21;

[0041] Rotating the first knob 15 drives the bidirectional screw 10 to rotate through the second bevel gear 14 and the first bevel gear 13. The rotating bidirectional screw 10 drives the two threaded seats 11 to approach each other, so as to drive the two pistons 5 in each horizontal pipe 2 to approach each other through the L-shaped plate 12, the mounting plate 7 and the corresponding extension rod 6. At the same time, the two limiting plates 17 are driven to approach each other through the two brackets 16 until the distance between the two limiting plates 17 is the same as the width of the non-woven fabric, and the distance between the two pistons 5 in each horizontal pipe 2 is also the same as the width of the non-woven fabric. Then, the liquid is conveyed into the two multi-way pipes 4 through an external liquid conveying device. The liquid enters each horizontal pipe 2 through the multi-way pipe 4 and then is sprayed out by each liquid spraying head 3 to add liquid to the upper and lower surfaces of the advancing non-woven fabric, so that the non-woven fabric becomes a wet wipe, realizing the production of wet wipes. The two limiting plates 17 can limit the advancing non-woven fabric. At the same time, since the distance between the two pistons 5 in each horizontal pipe 2 is the same as the width of the non-woven fabric, the liquid spraying heads 3 between the two pistons 5 in each horizontal pipe 2 will spray out the liquid. The liquid spraying heads 3 outside the pistons 5 will also be outside the non-woven fabric and will not spray out the liquid due to the obstruction of the pistons 5, thus avoiding the waste of liquid caused by the liquid spraying heads 3 outside the non-woven fabric spraying out the liquid;

[0042] As shown Figures 1-6 in the figure, the extrusion mechanism includes a threaded cylinder 22, a second screw 23, extrusion rollers 24, a second knob 25, and a limiting rod 26;

[0043] The threaded cylinder 22 is installed on the upper surface of the liquid adding tank 1 and is directly above the conveying roller 21 near the outlet 19. The second screw 23 is arranged inside the threaded cylinder 22. The extrusion rollers 24 are rotatably installed at the end of the second screw 23 extending into the liquid adding tank 1. The second knob 25 is installed at the upper end of the second screw 23. Two limiting rods 26 are installed on the upper surface of the extrusion rollers 24 and the upper ends extend to the outside of the liquid adding tank 1;

[0044] Before use, the second knob 25 drives the second screw 23 to rotate and descend through the threaded cylinder 22, and the descending second screw 23 drives the extrusion rollers 24 to descend, cooperating with the conveying roller 21 to squeeze the wet wipes between the two. Then, when the wet wipes pass between the extrusion rollers 24 and the conveying roller 21, the excess liquid in the wet wipes is squeezed out by the extrusion rollers 24 and the conveying roller 21, avoiding the occurrence of leakage caused by the wet wipes absorbing too much wet wipe liquid, ensuring the product quality of the wet wipes. The squeezed liquid falls into the liquid adding tank 1 for collection and can be discharged from the faucet at the bottom of the liquid adding tank 1 for reuse.
