Description

Technical Field

[0001] This application relates to the field of wet wipe production technology, and in particular to a liquid dispensing mechanism for wet wipe production. Background Technology

[0002] In the field of wet wipes production, the humidification mechanism applies a specific leachate evenly to the nonwoven fabric, thereby giving the wet wipes multiple functions such as cleaning, disinfection, and moisturizing. The liquid dispensing mechanism, as a crucial component of the humidification mechanism, directly impacts the quality and production efficiency of the wet wipes.

[0003] Currently, in most existing wet wipe production lines, the liquid dispensing mechanism of the humidification equipment is in use. Most of these mechanisms can only provide one type of humidifying liquid at a time. In actual production, different types of wet wipes require humidifying liquids with different ingredients and ratios.

[0004] Since only one type of humidifying liquid can be provided, when changing products, it takes time to clean the liquid preparation mechanism, re-mix the liquid, and inject the liquid. This is not only cumbersome, but also easily leads to production interruption and reduces overall production efficiency.

[0005] At the same time, frequent operations also increase labor costs and equipment wear and tear, raising production costs.

[0006] To address the aforementioned issues, a liquid preparation mechanism for wet wipe production is now designed. Utility Model Content

[0007] This application provides a liquid dispensing mechanism for wet wipe production to solve the problem in existing wet wipe production lines where most humidifying equipment liquid dispensing mechanisms can only provide one humidifying liquid at a time, leading to reduced production efficiency during product switching.

[0008] Firstly, a liquid dispensing mechanism for wet wipe production is provided, comprising: The liquid preparation tank and multiple interconnected mixing tanks, wherein the liquid preparation tank has a storage chamber for storing the wetting solution, and the mixing tank has a mixing chamber. The liquid preparation tank is equipped with a conveying unit, which is used to send the wetting liquid inside the storage chamber into the mixing chamber. The mixing tank is equipped with a stirrer and a feeding port, which is used to add functional additives into the mixing chamber. Multiple filtration units, which are connected to the corresponding mixing chambers, are used to remove impurities from the mixed liquid.

[0009] In some embodiments, the delivery unit includes a pump body disposed on a liquid mixing tank, the inlet of the pump body being connected to the liquid storage chamber, the outlet of the pump body being connected to a liquid distribution pipe, the bottom end of the liquid distribution pipe being connected to a plurality of delivery pipes, and the other end of the delivery pipe being connected to a corresponding mixing chamber.

[0010] In some embodiments, the stirrer includes: A drive motor and reducer are mounted above the mixing tank; Rotate the shaft located inside the mixing chamber; Multiple stirring spatulas arranged in a ring on the rotating shaft; The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the top of the rotating shaft.

[0011] In some embodiments, the filtering unit includes: Frame; Pump body two is mounted on the frame; A filter box installed on the frame and located above the second pump body; The inlet of the second pump body is connected to the mixing chamber via a pipe, and the outlet of the second pump body is connected to the filter box via a pipe.

[0012] In some embodiments, the filter box includes a box body, the upper and lower ends of which are arc-shaped; The housing is equipped with a filter screen, and the filter screen is provided with multiple partitions, which are distributed along the width of the filter screen. Both the filter screen and the separator are perforated metal meshes used to filter out fixed particles mixed in the leachate.

[0013] In some embodiments, the filter box further includes a feeding mechanism; The feeding mechanism includes a drain pipe located at the bottom of the filter box, the drain pipe being connected to the filter box, the other end of the drain pipe being connected to the inlet of the pump body three, and the outlet of the pump body three being connected to the humidification mechanism of the external production line through a pipe. A valve is installed on the drain pipe.

[0014] This application provides a liquid preparation mechanism for wet wipe production. Through the combined use of a liquid preparation tank, multiple interconnected mixing tanks, and a conveying unit stirrer, each mixing tank can independently perform liquid preparation operations, and multiple liquid preparations with different formulations can be prepared simultaneously. When switching products, production interruption can be avoided by supplying the corresponding humidifying liquid, thus ensuring production efficiency.

[0015] The stirrer ensures that the wetting liquid and functional additives are fully and evenly mixed in the mixing chamber. The uniform mixing ensures that the content of various components in the solution is stable, thus enabling the wet wipes to achieve consistent performance and quality during the production process.

[0016] By filtering the mixed liquid through the filtration unit, solid particulate impurities in the liquid can be removed, preventing these impurities from entering the wet wipe production process and affecting the appearance and quality of the wet wipes. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a liquid dispensing mechanism for wet wipe production, which solves the problem in existing wet wipe production lines where most humidifying equipment liquid dispensing mechanisms can only provide one humidifying liquid at a time, leading to reduced production efficiency during product switching.

[0022] Please see Figures 1-3 A liquid preparation mechanism for wet wipe production includes: a liquid preparation tank 1 and multiple interconnected mixing tanks 2. The liquid preparation tank 1 has a storage chamber 3 for storing the wetting liquid, and the mixing tanks 2 have a mixing chamber 4. The liquid preparation tank 1 is equipped with a conveying unit 5 for conveying the wetting liquid in the storage chamber 3 into the mixing chamber 4. The mixing tank 2 is equipped with a stirrer 6 and a feeding port 21 for adding functional additives into the mixing chamber 4. Multiple sets of filtration units 7 are connected to the corresponding mixing chambers 4 for removing impurities from the mixed liquid.

[0023] The storage chamber 3 inside the liquid preparation tank 1 is used to store the impregnation liquid. When it is necessary to transfer the impregnation liquid to the mixing tank 2, the conveying unit 5 starts to work, extracts the impregnation liquid in the storage chamber 3, and sends it into the mixing chamber 4 of the mixing tank 2 connected to it.

[0024] The mixing tank 2 is equipped with a feeding port 21, through which various functional additives are fed into the mixing chamber 4. These functional additives can be selected according to the different needs of the wet wipes, such as disinfectants, moisturizers, fragrances, etc.

[0025] After the impregnation liquid and functional additives enter the mixing chamber 4, the stirrer 6 installed inside the mixing tank 2 starts to operate. The stirrer 6 stirs the liquid in the mixing chamber 4, so that the impregnation liquid and functional additives are fully mixed and uniform, forming a solution that meets the requirements.

[0026] After the mixing tank 2 completes the liquid preparation and mixing, the liquid in the mixing chamber 4 flows into the filtration unit 7. The filtration unit 7 filters the incoming liquid to remove any solid particles that may be present, ensuring the purity of the final liquid preparation and improving the quality of the wet wipes.

[0027] By combining the liquid preparation tank 1, multiple interconnected mixing tanks 2, conveying unit 5, and agitator 6, each mixing tank 2 can independently perform liquid preparation operations, and multiple different formulations of liquid can be prepared simultaneously. When switching products, production interruption can be avoided and production efficiency can be guaranteed by supplying the corresponding humidifying liquid.

[0028] The stirrer 6 ensures that the wetting liquid and functional additives are fully and evenly mixed in the mixing chamber 4. The uniform mixing ensures that the content of various components in the solution is stable, thus enabling the wet wipes to obtain consistent performance and quality during the production process.

[0029] The filtration unit 7 filters and removes impurities from the mixed liquid, thus preventing these impurities from entering the wet wipes production process and affecting the appearance and quality of the wet wipes.

[0030] like Figure 1 and Figure 2 As shown, the conveying unit 5 in this embodiment includes a pump body 51 installed on the liquid mixing tank 1. The inlet of the pump body 51 is connected to the liquid storage chamber 3, and the outlet of the pump body 51 is connected to a liquid distribution pipe 52. The bottom end of the liquid distribution pipe 52 is connected to a plurality of conveying pipes 53, and the other end of the conveying pipe 53 is connected to the corresponding mixing chamber 4.

[0031] When it is necessary to transport the impregnating liquid in the storage chamber 3 of the mixing tank 1 to the mixing chamber 4 of each mixing tank 2, the pump body 51 starts to work, and a negative pressure is generated at the inlet of the pump body 51. Since the inlet of the pump body 51 is connected to the storage chamber 3, the impregnating liquid in the storage chamber 3 is drawn into the pump body 51 under the action of the negative pressure at the inlet.

[0032] The impregnating liquid drawn into the pump body 51 gains pressure under the action of the pump body 51 and flows out from the outlet of the pump body 51 into the liquid distribution pipe 52 connected to it. The liquid distribution pipe 52 plays the role of collecting and distributing the liquid, and evenly distributes the impregnating liquid flowing out from the pump body 51 into multiple delivery pipes 53 connected to the bottom.

[0033] The other end of each delivery pipe 53 is connected to the mixing chamber 4 of the corresponding mixing tank 2. The impregnation liquid is delivered to each mixing chamber 4 through the delivery pipe 53 to prepare for subsequent mixing with functional additives.

[0034] The combination of the liquid distribution pipe 52 and multiple conveying pipes 53 allows the impregnating liquid to be simultaneously conveyed to multiple mixing chambers 4, achieving parallel conveying. This avoids the tedious process of conveying liquid to the mixing tank 2 one by one, further improving overall production efficiency and reducing the production cycle.

[0035] The pump body 51 can usually control the flow rate of the conveying liquid by adjusting the speed of the motor and the displacement of the pump, thereby adjusting the amount of wetting liquid conveyed and ensuring that the amount of wetting liquid added to each mixing chamber 4 is accurate. This is existing technology and will not be described in detail here.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the stirrer 6 includes: a drive motor 61 and a reducer 62 disposed above the mixing tank 2; a rotating shaft 63 rotatably disposed inside the mixing chamber 4; and a plurality of stirring shovels 64 arranged in a ring on the rotating shaft 63; the output shaft of the drive motor 61 is connected to the input shaft of the reducer 62, and the output shaft of the reducer 62 is connected to the top end of the rotating shaft 63.

[0037] When it is necessary to stir and mix the impregnation liquid and functional additives in the mixing chamber 4, the drive motor 61 starts to run, converts electrical energy into mechanical energy, and its output shaft starts to rotate at high speed.

[0038] The output shaft of the drive motor 61 is connected to the input shaft of the reducer 62. The high-speed rotating power is transmitted to the reducer 62. The reducer 62 reduces the input high-speed power and increases the torque through internal gear transmission or other reduction mechanisms, and then outputs low-speed, high-torque power from its output shaft.

[0039] The decelerated power drives the rotating shaft 63 to start rotating. The rotation of the rotating shaft 63 will drive the stirring spatula 64 to make a circular motion. When the stirring spatula 64 makes a circular motion in the mixing chamber 4, it will generate a stirring and shearing effect on the surrounding liquid, which can break the layered state between the impregnation liquid and the functional additives, so that they can fully contact and mix. As the stirring continues, a uniform liquid is eventually formed.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the filter unit 7 includes: a frame 71, a second pump body 72 disposed on the frame 71; and a filter box 73 disposed on the frame 71 and located above the second pump body 72. The inlet of the second pump body 72 is connected to the mixing chamber 4 through a pipe, and the outlet of the second pump body 72 is connected to the filter box 73 through a pipe.

[0041] When the solution in mixing chamber 4 is mixed and needs to be filtered, pump body 2 72 starts to work. Pump body 2 72 generates negative pressure at the inlet. Since the inlet of pump body 2 72 is connected to mixing chamber 4 through a pipe, the solution in mixing chamber 4 is drawn into pump body 2 72 under the action of negative pressure.

[0042] The liquid being drawn into the second pump body 72 is pressurized by the action of the second pump body 72, flows out from the outlet of the second pump body 72, and is transported to the filter box 73 along the pipeline.

[0043] The filter box 73 intercepts insoluble substances such as particles in the solution through the filter medium, while the pure solution passes through the filter medium to complete the filtration process and obtain a filtrate that meets the quality requirements.

[0044] like Figure 3 and Figure 4 As shown, the filter box 73 further includes a box body 731, the upper and lower ends of which are arc-shaped; a filter screen 732 is provided inside the box body 731, and a plurality of partition plates 733 are provided on the filter screen 732, the plurality of partition plates 733 being distributed along the width of the filter screen 732; both the filter screen 732 and the partition plates 733 are perforated metal meshes, used to filter fixed particles mixed in the leachate.

[0045] The leachate flows downward under the influence of gravity and comes into contact with the filter screen 732 set inside the housing 731. The filter screen 732 is a perforated metal mesh with numerous regular holes distributed on its surface. The liquid part of the leachate can continue to flow downward through these holes, while the mixed solid particles are intercepted by the filter screen 732, adhering to the surface of the filter screen 732 or getting stuck in the holes, thereby achieving solid-liquid separation.

[0046] Multiple separators 733 are provided on the filter screen 732 and distributed along the width of the filter screen 732. When the leachate flows through the filter screen 732, the separators 733 divide the flow area of ​​the leachate, so that the leachate flows in different separated areas.

[0047] This division alters the flow path of the leachate, increasing its flow distance and residence time on the filter screen 732. This allows the leachate more opportunities to contact the filter screen 732, resulting in more solid particles being intercepted by the filter screen 732 and further improving the filtration effect.

[0048] The filtrate after being filtered by filter screen 732 continues to flow downwards. Since the lower end of the box 731 is also arc-shaped, the filtrate will converge along the arc-shaped inner wall to the outlet at the bottom of the box 731, and then flow out of the filter box 73 through the pipe to enter the subsequent production process.

[0049] Both the top and bottom ends of the housing 731 are arc-shaped. The arc shape at the bottom end facilitates the collection and outflow of filtrate, reduces filtrate residue at the bottom of the housing 731, improves filtrate collection efficiency, and also ensures the continuity and stability of the filtration process.

[0050] The separator 733 on the filter screen 732 divides the flow area of ​​the leachate, increasing the contact area and contact time between the leachate and the filter screen 732, making it easier for solid particles to be intercepted, and improving the filtration accuracy and filtration efficiency.

[0051] Both filter screen 732 and separator plate 733 are made of perforated metal mesh. Metal has high strength and hardness, capable of withstanding the pressure of the leachate and the impact of solid particles, and is not easily deformed or damaged. Compared to filter screens made of other materials, perforated metal mesh has a longer service life, reducing the frequency of filter replacement and lowering production costs. This is existing technology and will not be elaborated further.

[0052] like Figure 3 and Figure 4 As shown, it should be noted that the filter box 73 in this embodiment also includes a feeding mechanism 8; the feeding mechanism 8 includes a drain pipe 81 located at the bottom of the filter box 73, the drain pipe 81 is connected to the filter box 73, the other end of the drain pipe 81 is connected to the inlet of the pump body 82, and the outlet of the pump body 82 is connected to the humidification structure of the external production line through a pipe; a valve 83 is provided on the drain pipe 81.

[0053] After the humidifying liquid passes through the filter screen 732 and the separator 733 inside the filter box 73, solid particles are intercepted, and the pure filtrate collects at the bottom of the filter box 73 under the action of gravity.

[0054] When it is necessary to supply filtrate to the humidification components of the external production line, the valve 83 installed on the drain pipe 81 is opened. The valve 83 controls the flow of filtrate. When feeding is not required, the valve 83 is closed to prevent filtrate leakage. When feeding is required, the valve 83 is opened to allow the filtrate to pass through the drain pipe 81.

[0055] After valve 83 is opened, pump body 3 82 starts to work. Pump body 3 82 generates negative pressure in the drain pipe 81 through its inlet. The filtrate collected at the bottom of filter box 73 is sucked into the drain pipe 81 under the action of negative pressure and then enters the interior of pump body 3 82.

[0056] The filtrate entering the pump body 3 82 is pressurized by the action of the pump body 3 82, flows out from the outlet of the pump body 3 82, and is transported through pipelines to the humidification components of the external production line to provide the required liquid for the humidification process of the production line.

[0057] The feeding mechanism 8 establishes a dedicated conveying channel from the filter box 73 to the external production line humidification components through the connection of the drain pipe 81, the pump body 82 and the pipeline. This ensures that the filtered liquid can be accurately delivered to the parts that need humidification, meeting the liquid supply requirements of the production line for the humidification process and guaranteeing the smooth operation of the production process.
