Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a liquid dispensing mechanism for wet wipes. Background Technology

[0002] In the industrial production process of wet wipes, folding the base fabric is a crucial preliminary step. The folded surfaces (such as multi-layered bonding surfaces) and folded corners (sharp corners at bends and surrounding wrinkles) easily form closed or semi-closed microcavities that trap a large amount of air. During the liquid application stage, when the liquid is sprayed and impregnated onto the base fabric surface, the gas trapped in the folded areas cannot escape quickly, forming an "air barrier" inside the base fabric. This barrier occupies the gaps between the fabric fibers, hindering the liquid from penetrating and diffusing along the fiber gaps. Consequently, the liquid remains only on the surface or in the unfolded areas, failing to evenly wet the core areas of the folded surfaces and corners. After the pressure roller squeezes out excess water, air bubbles are also squeezed out. Liquid in other parts of the wet wipe slowly seeps to where the air bubbles were, ultimately resulting in a lower overall liquid content. Finished wet wipes have a shelf life of 2-3 years. During this period, the liquid content of the wipes gradually decreases. If the liquid content is too low, the wipes may become dehydrated before the expiration date, affecting the user experience. If too much liquid is left over when the pressure roller squeezes out excess water, excessive liquid application will cause the non-folded area to become saturated and drip, increasing raw material loss and the difficulty of subsequent packaging processes.

[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a wet wipe liquid application mechanism to solve the problem of air affecting liquid application at the fold.

[0005] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a wet wipe liquid dispensing mechanism, comprising a liquid dispensing tank formed by sealing and splicing front, rear, left, and right panels and a bottom plate, wherein a liquid receiving groove is provided at the bottom of the liquid dispensing tank, characterized in that: a cover plate is provided at the top of the rear end of the liquid dispensing tank, mounting strips are respectively provided on the left and right sides of the cover plate, a connecting rod is vertically fixed at the free end of the mounting strip, a mounting seat is provided at the lower end of the connecting rod, a first liquid dispensing pipe and a second liquid dispensing pipe are horizontally arranged at the front and rear ends of the mounting seat, and a liquid outlet groove is opened along the axial direction at the lower end of the first liquid dispensing pipe and the second liquid dispensing pipe, and an exhaust clamping roller is rotatably arranged between the first liquid dispensing pipe and the second liquid dispensing pipe on the mounting seat, and a draining device for controlling the amount of liquid dispensing on the wet wipe is provided below the cover plate; the connecting rod is fixedly arranged on the outer surface of the mounting seat, and the exhaust clamping roller is arranged on the inner surface of the mounting seat.

[0006] A further improvement is that: the first liquid inlet pipe and the second liquid inlet pipe are respectively provided with adjustable rubber limiting sleeves at both ends, and the rubber limiting sleeves are elastically fitted on the outer surface of the first liquid inlet pipe and the second liquid inlet pipe.

[0007] A further improvement is that the front and rear ends of the mounting base are respectively provided with horizontal insertion slots, the first liquid supply pipe and the second liquid supply pipe are respectively horizontally inserted into the insertion slots, and the front and rear ends of the mounting base are respectively provided with threaded holes that communicate with the insertion slots. Bolts are screwed into the threaded holes, and the tail of the bolts abuts against the surface of the first liquid supply pipe and the second liquid supply pipe.

[0008] A further improvement is that: the free end of the mounting strip has a longitudinally formed mounting hole, and the free end of the mounting strip has a clamping groove connected to the mounting hole along the front-back direction; the upper end of the connecting rod passes through the mounting hole; and the free end of the mounting strip is detachably equipped with a locking fastener for closing the clamping groove to clamp the connecting rod.

[0009] A further improvement is made to the following: the drainage device includes a lower pressure roller, an upper pressure roller, an inverted U-shaped sliding frame, and a mounting block. The mounting block is fixedly disposed in the middle of the lower surface of the cover plate. The two ends of the inverted U-shaped sliding frame are respectively slidably disposed on the inner wall of the upper liquid tank and the side end face of the mounting block. The upper pressure roller is rotatably disposed inside the inverted U-shaped sliding frame. The lower pressure roller is located below the upper pressure roller and rotatably disposed on the inner wall of the upper liquid tank. The cover plate is provided with an adjustment structure for adjusting the position of the inverted U-shaped sliding frame to adjust the clamping gap between the upper and lower pressure rollers.

[0010] A further improvement is made to the adjustment structure, which includes a threaded rod and a threaded sleeve. An adjustment hole is provided through the cover plate, and the threaded sleeve is fixedly inserted into the adjustment hole. The threaded rod is threadedly connected to the threaded sleeve. The lower end of the threaded rod is rotatably mounted on the inverted U-shaped sliding frame, and a handwheel is fixedly mounted on the upper end of the threaded rod.

[0011] A further improvement is that guide strips are provided on both the inner wall of the upper liquid tank and the side end face of the mounting block, and guide grooves are provided at both ends of the inverted U-shaped sliding frame to slide and cooperate with the guide strips.

[0012] A further improvement is that the surface of the lower pressure roller is uniformly provided with grooves along the axial direction for intermittently applying pressure to the wet wipe base fabric.

[0013] A further improvement is that the front and rear walls of the liquid receiving tank are inclined surfaces.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are: 1. In this case, an exhaust clamping roller is used in conjunction with the first and second liquid-filling pipes. Through a progressive liquid-filling process of "first liquid-exhaust wetting-second liquid-filling," the problem of air trapped inside the folded base fabric and forming an "air barrier" is fundamentally solved. After the wet wipe base fabric is initially wetted by the first liquid-filling pipe, the clamping action of the exhaust clamping roller can directly force out the gas stored in key areas such as the folded surface and folded corners, while simultaneously achieving initial complete wetting of the base fabric under clamping pressure. The subsequent second liquid-filling through the second liquid-filling pipe ensures that the liquid penetrates evenly to the core positions of the folded surface and folded corners, significantly improving the overall uniformity of wet wipe wetting. This is beneficial for increasing the traction and conveying speed of the base fabric and improving the production efficiency of wet wipes.

[0015] 2. The rubber limiting sleeves at both ends of the first and second liquid supply pipes are adjustable to accommodate base fabrics of different widths; the bolt structure on the mounting base can fix and fine-tune the position of the liquid supply pipes to ensure accurate liquid supply; the mounting holes and clamping grooves on the mounting strip, combined with locking fasteners, allow for adjustment of the connecting rod's installation height, thus adapting to different transmission requirements; the clamping gap between the upper and lower pressure rollers can be flexibly adjusted according to the base fabric specifications. These designs enable the mechanism to adapt to the production of various wet wipe base fabrics with different folding layers (double, triple, quadruple, etc.), thicknesses, and widths, significantly improving the equipment's versatility and applicability, and reducing equipment adjustment costs when companies change production specifications.

[0016] 3. The uniformly spaced grooves on the surface of the lower pressure roller create a secondary clamping and venting effect on the base fabric through alternating "virtual clamping" and "solid clamping." This structure increases the clamping force, thoroughly squeezing out any residual air bubbles that haven't been completely expelled from the base fabric, fundamentally eliminating the presence of air bubbles and further ensuring uniform wetting. Simultaneously, the squeezed-out water flows to both ends of the grooves and fills them. After the air bubbles are expelled, the water in the grooves is quickly absorbed by the base fabric at the original bubble location, achieving efficient liquid absorption and stable moisture content control during rapid transmission. The thorough removal of air bubbles through the secondary clamping and venting mechanism in this case helps improve the base fabric's conveying speed, significantly increasing the processing efficiency and output of wet wipes.

[0017] 4. The liquid receiving tank at the bottom of the liquid tank has an inclined front and rear wall design, which can effectively prevent the liquid from splashing out of the receiving tank during the liquid feeding and extrusion of the pressure roller. This facilitates the centralized collection and reuse of excess liquid, further reducing raw material loss and avoiding the pollution of production equipment and production environment by dripping liquid, thus improving the cleanliness and standardization of the production site.

[0025] The free end of the mounting strip 13 has a longitudinally formed mounting hole 21, and the free end of the mounting strip 13 has a clamping groove 22 communicating with the mounting hole 21 in the front-back direction. The upper end of the connecting rod 14 passes through the mounting hole 21.

The lower pressure roller 24 is located below the upper pressure roller 25 and rotatably disposed on the inner wall of the upper liquid tank 10. The surface of the lower pressure roller 24 has grooves 32 evenly distributed axially for intermittently applying pressure to the wet wipe base fabric. The cover plate 12 is provided with an adjustment structure for adjusting the position of the inverted U-shaped sliding frame 26 to adjust the clamping gap between the upper pressure roller 25 and the lower pressure roller 24.

[0027] The adjustment structure includes a threaded rod 28 and a threaded sleeve 29. An adjustment hole is provided through the cover plate 12 in the middle of the inverted U-shaped sliding frame 26. The threaded sleeve 29 is fixedly inserted into the adjustment hole. The threaded rod 28 is threadedly connected to the threaded sleeve 29.

[0028] Guide strips 31 are provided on the inner wall of the upper liquid tank 10 and the side end face of the mounting block 27. Guide grooves that slide and cooperate with the guide strips 31 are provided at both ends of the inverted U-shaped sliding frame 26.

[0029] How to use a liquid dispensing mechanism for wet wipes: The wet wipe base fabric passes sequentially around the bottom of the first liquid inlet pipe 16, the clamping gap of the venting roller 18, and the bottom of the second liquid inlet pipe 17. The first liquid inlet pipe 16 first wets the base fabric, and the venting roller 18 clamps the fabric to expel the gas inside and completely wet it. The second liquid inlet pipe 17 applies liquid a second time to the base fabric to ensure that the base fabric absorbs sufficient liquid evenly. After absorbing the liquid, the base fabric passes between the upper pressure roller 25 and the lower pressure roller 24, where excess water is squeezed out, allowing the base fabric to absorb water without dripping.

[0030] The position of the inverted U-shaped sliding frame 26 can be adjusted according to the number of folds of the wet wipe base fabric (such as folding into two, three, or four layers) and the thickness of the base fabric, so as to adjust the clamping space between the upper and lower pressure rollers 24. The smaller the clamping space, the more water is squeezed out from the saturated wet wipe.

[0031] The surface of the lower pressure roller 24 is uniformly grooved along the axial direction for intermittently applying pressure to the wet wipe base fabric. The presence of the grooves causes the clamping of the lower pressure roller 24 and the upper pressure roller 25 to alternate between loose and solid clamping, which helps to reduce the clamping space and increase the clamping force acting on the base fabric. If there are still air bubbles in the base fabric, they can be discharged a second time under the pressure of the upper and lower pressure rollers 24. The squeezed water flows to both ends of the groove to fill the groove. After the air bubbles are discharged, the water in the groove can be absorbed by the base fabric at the original air bubble location. This helps to control the moisture content of the base fabric under rapid transmission and improve the production efficiency of wet wipes.
