Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin surface layer treatment technology, and in particular to a sanitary napkin surface layer roller coating hydrophilic liquid application machine. Background Technology

[0002] In the production of absorbent hygiene products such as sanitary napkins and diapers, the hydrophilic treatment of the surface material is a core process that affects the product's absorption speed and dry feel. A roller-coating hydrophilic liquid application machine is the key equipment for implementing this process. It evenly coats a specific amount of hydrophilic finishing agent onto the surface non-woven fabric or cotton soft material, transforming it from hydrophobic to hydrophilic, thereby achieving rapid liquid penetration and diversion.

[0003] Chinese patent CN211596029U discloses a hydrophilic agent coating for nonwoven fabrics, including a rectangular table with a movable coating structure. The movable coating structure includes a support rod, a slot, a rectangular through hole, a box A, a water pump, a connecting pipe, a rolling rod A, a top cover, a notch, a box B, a guide plate, a gantry frame, a rolling rod B, an L-shaped plate, a sliding through hole, a sliding rod, a connecting pipe, a rectangular plate, a cavity, a mesh, a vertical rod, a rotating hole, a round rod, and a rocker arm. This design ensures that the hydrophilic agent is evenly applied to the surface of the nonwoven fabric and dries it promptly, avoiding splashing, preventing waste of excess material, and collecting and reusing excess hydrophilic agent.

[0004] However, in the above-mentioned solutions, the hydrophilic agent is prone to solid component precipitation and stratification when left to stand, and is also prone to generating bubbles when agitated by the anilox roller. These problems directly lead to uneven concentration and viscosity of the adhesive, which in turn affects the stability of the liquid carried by the anilox roller and is one of the main causes of coating defects. Traditional equipment can usually only achieve liquid loading of a single concentration and a single mode, which is difficult to meet the market's demand for diversified product functions. It also lacks an efficient online cleaning system, resulting in long equipment cleaning and maintenance time and affecting overall production efficiency. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a hydrophilic liquid coating machine for the surface layer of sanitary napkins.

[0006] This utility model proposes a sanitary napkin surface coating hydrophilic liquid application machine, which includes a cabinet integrating the equipment. The cabinet is equipped with supporting legs. A drive motor is fixedly connected to the outer surface of one side of the supporting legs. A textured roller is rotatably connected to the inner surface of the supporting legs. An adhesive treatment mechanism is provided on the inner surface of the supporting legs. The adhesive treatment mechanism includes a lip sealing scraper. The lip sealing scraper contacts the surface of the rotating textured roller and scrapes off excess adhesive from its surface.

[0007] Preferably, the adhesive treatment mechanism further includes a transmission gear set installed on one side surface of the support foot, wherein the transmission gear in the transmission gear set is fixedly sleeved with the outer surface of the roller shaft of the anilox roller, an immersion tank is installed on the inner surface of the support foot, and the outer surface of the anilox roller is slidably connected to the inner surface of the immersion tank.

[0008] Through the above technical solution, in order to coat the surface layer of the sanitary napkin with a hydrophilic agent, a hydrophilic agent is placed in the soaking tank, and a liquid inlet replenishment pipe and a drain pipe for cleaning can be set in the soaking tank. A part of the anilox roller is in contact with the hydrophilic agent. The surface of the anilox roller is covered with extremely small and uniform pits, called cells. The drive motor controls the anilox roller to rotate at a uniform speed through the transmission gear set, so that the cells carry the hydrophilic agent. When the anilox roller comes into contact with the surface layer, it can transfer the hydrophilic agent to the surface layer. The lip sealing scraper is made of flexible rubber material, which fits precisely with the anilox roller and can thoroughly and smoothly scrape off all excess hydrophilic agent on the roller surface except for the inside of the cells.

[0009] Preferably, a hinge plate is fixedly connected to one side surface of the lip sealing scraper, and support ear plates are fixedly connected to the lower surface of the hinge plate in a symmetrical manner.

[0010] Through the above technical solution, in order to adjust the contact pressure of the lip sealing scraper, the hinge plate drives the lip sealing scraper to rotate. The rotation changes the contact angle between the scraper and the surface of the anilox roller. This is crucial for adapting to hydrophilic agents of different viscosities and obtaining the best scraping effect. Through a stable and finely adjustable mechanical mounting structure, precise control of the scraper's working angle and pressure is achieved, and uniform contact between the scraper and the anilox roller along its entire length is ensured. This lays a solid mechanical foundation for the uniformity, stability, and ease of maintenance of the equipment.

[0011] Preferably, the adhesive treatment mechanism further includes a fixed shaft fixedly connected to the inner surface of the support foot, and the outer surface of the fixed shaft is fixedly connected to symmetrically distributed push cylinders through a fixed connecting plate, and the piston rod surface of the push cylinder is hinged to the free end of the support ear plate.

[0012] Through the above technical solution, in order to push the hinge plate, the cylinder pushes the free end of the support ear plate, thereby adjusting the angle of the lip sealing scraper to adapt to the rotation speed of the anilox roller and to fit against its surface.

[0013] Preferably, the adhesive treatment mechanism further includes a stirring shaft arranged in an arc-shaped path along the arc-shaped inner wall of the immersion tank. Rubber scrapers are fixedly connected to the outer surface of the stirring shaft in a ring array, and the outer surface of the rubber scrapers is slidably connected to the inner wall of the immersion tank.

[0014] With the above technical solution, when the anilox roller rotates in the immersion tank, it is easy to entrain air into the hydrophilic agent, generating foam. The foam carried to the roller surface will affect the uniformity of coating. The solid components in the hydrophilic agent are prone to precipitation or stratification when left to stand. To avoid this, multiple stirring shafts drive the rubber scraper to rotate synchronously with the anilox roller. When the rubber scraper rotates, it ensures that the concentration and viscosity of the hydrophilic agent in the immersion tank remain uniform and stable, avoiding the generation of bubbles. At the same time, stirring the hydrophilic agent can achieve liquid turbulence and create fluctuations, thereby ensuring that the cells of the anilox roller are filled with hydrophilic agent. Then, the lip sealing scraper can remove excess hydrophilic agent, thus achieving full and uniform hydrophilic agent in the cells.

[0015] Preferably, one end of the stirring shaft extends to the other side surface of the support foot, and the outer surfaces of adjacent stirring shafts are fixedly fitted with intermeshing linkage gears, and the outer surface of one of the transmission shafts of the transmission gear set is fixedly fitted with a meshing gear, which meshes with one of the linkage gears.

[0016] Through the above technical solution, all adjacent stirring shafts mesh with each other through the linkage gears at their ends to form a gear array. The power source comes from the existing transmission system. On one of the existing transmission shafts in the transmission gear set, a meshing gear is added. By meshing this gear with any one of the linkage gears in the stirring shaft set, the power of the main equipment can be distributed to the stirring system. In other words, the stirring system is seamlessly integrated into the power chain of the main equipment in an extremely ingenious and low-cost way, creating an overall solution that is absolutely synchronized, speed-linked, compact in structure, and highly reliable.

[0017] Preferably, the adhesive treatment mechanism further includes a sliding plate installed on one side surface of the upper end of the support foot through the cooperation of a linear guide rail and a linear slider. That is, the sliding plate moves linearly on one side of the linear guide rail. One side surface of the sliding plate is rotatably connected to a backing roller distributed vertically. The lower end of the backing roller is positioned above the anilox roller. An adjusting cylinder is fixedly connected to the upper surface of the support foot. One side surface of the cylinder bodies of the two adjusting cylinders is fixedly connected to a cleaning liquid spraying system through a partition.

[0018] Through the above technical solution, in order to achieve adhesive coating on the surface layer, the lower adhesive roller is used for normal operation, cooperating with the anilox roller to form a coating pressure zone, so that the adhesive is evenly coated and spread on the surface layer. The height of the adhesive roller is adjusted by adjusting the cylinder, thereby adjusting the pressure of the adhesive roller on the surface layer, so that the anilox roller can rotate at a uniform speed to achieve adhesive spreading. In order to facilitate the cleaning of the anilox roller and the adhesive roller and improve work efficiency, a motor is installed on one side of the sliding plate to drive the upper adhesive roller to rotate, so that the two adhesive rollers rotate. At this time, the cleaning liquid spraying system sprays cleaning liquid onto the surface of the adhesive roller. The cleaning is completed when the adhesive roller rotates. Then the cleaning liquid is sprayed onto the surface of the anilox roller. With the rotation of the anilox roller, the initial cleaning of the anilox roller can be achieved. The cleaning liquid is finally collected in the immersion tank. With the rotation of the rubber scraper, the immersion tank is cleaned. Finally, the cleaning liquid is drained. The cleaning liquid spraying system includes a liquid storage and transportation unit, a spraying execution unit, and valves and control units.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up a precision pressure adjustment mechanism consisting of a hinge plate, a support ear plate, and a push cylinder, the angle and pressure of the lip sealing scraper are automatically and with high precision, ensuring uniform and stable adhesion between the scraper and the anilox roller along the entire length. This effectively solves the problem of uneven liquid application caused by the inconvenience of scraper adjustment in traditional equipment, and significantly improves the uniformity and consistency of hydrophilic agent coating.

[0021] 2. By setting up an arc-shaped array of stirring shafts and rubber scrapers in the immersion tank, and using a linkage gear to mesh with the main drive system, synchronous, gentle and continuous stirring of the adhesive liquid is achieved. This design effectively prevents the precipitation, stratification and foaming of the hydrophilic agent, ensuring the stability of the working liquid from the source. This lays a solid foundation for the anilox roller to stably and uniformly carry the adhesive liquid. At the same time, the structure is compact, the power source is ingenious, and the reliability is high.

[0022] 3. By setting up a sliding plate module based on linear guide rails, upper and lower adhesive rollers, and an integrated cleaning liquid spraying system, a multi-functional module integrating coating, adjustment, and online cleaning is constructed. This design greatly facilitates the maintenance of adhesive rollers and the automated cleaning of anilox rollers, adhesive rollers, and immersion tanks, significantly reducing equipment maintenance downtime, improving production efficiency and ease of operation, and enhancing the functional flexibility of the equipment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-8 A hydrophilic liquid coating machine for the surface layer of sanitary napkins includes a cabinet 1 that integrates the equipment. The cabinet 1 has a support leg 2 inside. A drive motor 3 is fixedly connected to the outer surface of one side of the support leg 2. A textured roller 4 is rotatably connected to the inner surface of the support leg 2. An adhesive treatment mechanism is provided on the inner surface of the support leg 2. The adhesive treatment mechanism includes a lip sealing scraper 5. The lip sealing scraper 5 contacts the surface of the rotating textured roller 4 and scrapes off excess adhesive from its surface.

[0034] To apply a hydrophilic agent to the surface layer of the sanitary napkin, the adhesive treatment mechanism also includes a transmission gear set 6 installed on one side of the support foot 2. The transmission gear in the transmission gear set 6 is fixedly sleeved with the outer surface of the roller shaft of the anilox roller 4. An immersion tank 7 is installed on the inner surface of the support foot 2. The outer surface of the anilox roller 4 is slidably connected to the inner surface of the immersion tank 7. The immersion tank 7 contains a hydrophilic agent, and an inlet replenishment pipe and a drain pipe for cleaning can be installed in the immersion tank 7. A part of the anilox roller 4 is in contact with the hydrophilic agent. The surface of the anilox roller 4 is covered with extremely small, uniform pits, called cells. The drive motor 3 controls the anilox roller 4 to rotate at a uniform speed through the transmission gear set 6, so that the cells carry the hydrophilic agent. When the anilox roller 4 comes into contact with the surface layer, it can transfer the hydrophilic agent to the surface layer. The lip sealing scraper 5 is made of flexible rubber material, which fits precisely with the anilox roller 4 and can thoroughly and smoothly scrape off all excess hydrophilic agent on the roller surface except for the inside of the cells.

[0035] By setting up a precision pressure regulating mechanism consisting of a hinge plate 8, a support ear plate 9, and a push cylinder 11, the angle and pressure of the lip sealing scraper 5 are automatically and with high precision controlled, ensuring uniform and stable adhesion between the scraper and the anilox roller 4 along its entire length. This effectively solves the problem of uneven liquid application caused by the inconvenience of scraper adjustment in traditional equipment, and significantly improves the uniformity and consistency of hydrophilic agent coating.

[0036] To adjust the contact pressure of the lip sealing scraper 5, a hinge plate 8 is fixedly connected to one side surface of the lip sealing scraper 5. Support ear plates 9 are symmetrically distributed and fixedly connected to the lower surface of the hinge plate 8. The hinge plate 8 drives the lip sealing scraper 5 to rotate, which changes the contact angle between the scraper and the surface of the anilox roller 4. This is crucial for adapting to hydrophilic agents of different viscosities and obtaining the best scraping effect. Through a stable and finely adjustable mechanical mounting structure, precise control of the scraper's working angle and pressure is achieved, and uniform contact between the scraper and the anilox roller 4 along its entire length is ensured. This lays a solid mechanical foundation for the uniformity, stability, and ease of maintenance of the equipment.

[0037] In order to push the hinge plate 8, the adhesive treatment mechanism also includes a fixed shaft 10 fixedly connected to the inner surface of the support foot 2. The outer surface of the fixed shaft 10 is fixedly connected to a symmetrically distributed push cylinder 11 through a fixed connecting plate. The piston rod surface of the push cylinder 11 is hinged to the free end of the support ear plate 9. The push cylinder 11 pushes the free end of the support ear plate 9, thereby adjusting the angle of the lip sealing scraper 5 to adapt to the rotation speed of the anilox roller 4 and to adhere to its surface.

[0038] By using the arc-shaped array of stirring shafts 12 and rubber scrapers 13 arranged in the immersion tank 7, and the linkage gear 14 meshing with the main drive system, synchronous, gentle and continuous stirring of the adhesive liquid is achieved. This design effectively prevents the precipitation, stratification and foaming of hydrophilic agents, ensuring the stability of the working liquid from the source. It lays a solid foundation for the stable and uniform carrying of the adhesive liquid by the anilox roller 4. At the same time, the structure is compact, the power source is ingenious and the reliability is high.

[0039] When the anilox roller 4 rotates in the immersion tank 7, it easily draws air into the hydrophilic agent, generating foam. The foam carried to the roller surface affects the uniformity of coating. The solid components in the hydrophilic agent are prone to precipitation or stratification when left to stand. To avoid this, the adhesive treatment mechanism also includes stirring shafts 12 arranged in an arc-shaped path along the arc-shaped inner wall of the immersion tank 7. Rubber scrapers 13 are fixedly connected to the outer surface of the stirring shafts 12 in a ring array. The outer surface of the rubber scrapers 13 is slidably connected to the inner wall of the immersion tank 7. Multiple stirring shafts 12 drive the rubber scrapers 13 to rotate synchronously with the anilox roller 4. When the rubber scrapers 13 rotate, they ensure that the concentration and viscosity of the hydrophilic agent in the immersion tank 7 remain uniform and stable, avoiding the generation of bubbles. At the same time, stirring the hydrophilic agent can achieve liquid turbulence and create fluctuations, thereby ensuring that the cells of the anilox roller 4 are filled with hydrophilic agent. Then, the lip sealing scraper 5 can scrape off the excess hydrophilic agent, thus achieving full and uniform hydrophilic agent in the cells.

[0040] One end of the stirring shaft 12 extends to the other side surface of the supporting foot 2, and the outer surfaces of adjacent stirring shafts 12 are fixedly fitted with intermeshing linkage gears 14. The outer surface of one of the transmission shafts of the transmission gear set 6 is fixedly fitted with a meshing gear 15, which meshes with one of the linkage gears 14. All adjacent stirring shafts 12 mesh with each other through the linkage gears 14 at their ends, forming a gear array. The power source comes from the existing transmission system. On one of the existing transmission shafts in the transmission gear set 6, a meshing gear 15 is added. This gear meshes with any one of the linkage gears 14 in the stirring shaft 12 set, and the power of the main equipment can be distributed to the stirring system. In other words, the stirring system is seamlessly integrated into the power chain of the main equipment in an extremely ingenious and low-cost way, creating an overall solution that is absolutely synchronized, speed-linked, compact in structure, and highly reliable.

[0041] To ensure proper coating of the adhesive on the surface layer, the adhesive processing mechanism also includes a sliding plate 16 mounted on one side of the upper end of the support foot 2 via a linear guide rail and a linear slider. The sliding plate 16 moves linearly along one side of the linear guide rail. A backing roller 17 is rotatably connected to one side of the sliding plate 16, distributed vertically. The lower backing roller 17 is positioned above the anilox roller 4. Adjusting cylinders 18 are fixedly connected to the upper surface of the support foot 2. A cleaning fluid spraying system 19 is fixedly connected to one side of each of the two adjusting cylinders 18 via a partition. The lower backing roller 17 is used for normal operation, forming a coating pressure zone with the anilox roller 4, allowing the adhesive to be evenly coated and spread on the surface layer. The height of the backing roller 17 is adjusted by adjusting the cylinders 18, thereby adjusting the backing roller 17's position on the surface layer. The pressure causes the anilox roller 4 to rotate at a constant speed, thus spreading the adhesive. To facilitate the cleaning of the anilox roller 4 and the adhesive backing roller 17 and improve work efficiency, a motor is installed on one side of the sliding plate 16 to drive the upper adhesive backing roller 17 to rotate, so that the two adhesive backing rollers 17 can rotate. At this time, the cleaning liquid spraying system 19 sprays the cleaning liquid onto the surface of the adhesive backing roller 17. The adhesive backing roller 17 completes the cleaning when it rotates. Then the cleaning liquid is sprayed onto the surface of the anilox roller 4. As the anilox roller 4 rotates, the anilox roller 4 can be initially cleaned. The cleaning liquid is finally collected in the immersion tank 7. The immersion tank 7 is cleaned as the rubber scraper 13 rotates. Finally, the cleaning liquid is drained. The cleaning liquid spraying system 19 includes a liquid storage and conveying unit, a spraying execution unit, and a valve and control unit.

[0042] By setting up a sliding plate module 16 based on a linear guide rail, upper and lower adhesive rollers 17, and an integrated cleaning liquid spraying system 19, a multi-functional module integrating coating, adjustment, and online cleaning is constructed. This design greatly facilitates the maintenance of the adhesive roller 17 and the automated cleaning of the anilox roller 4, adhesive roller 17, and immersion tank 7, significantly reducing equipment maintenance downtime, improving production efficiency and ease of operation, and enhancing the functional flexibility of the equipment.

[0043] Working principle: In a specific embodiment of this utility model, the operator selects the production formula on the human-machine interface. At the initial stage of the equipment, the control system controls the symmetrically distributed push cylinders 11 to move according to the formula instructions, automatically adjusting the lip sealing scraper 5 to the preset pressure and angle to ensure uniform adhesion with the anilox roller 4. The hydrophilic agent is injected into the immersion tank 7 to the working liquid level.

[0044] The drive motor 3 starts and drives the anilox roller 4 to rotate at a constant speed through the transmission gear set 6. The lower half of the rotating anilox roller 4 is immersed in the immersion tank 7, and the mesh cells on its surface carry the hydrophilic agent. When the anilox roller 4 rotates and passes the lip sealing scraper 5, the lip sealing scraper 5 precisely scrapes away all the excess hydrophilic agent outside the mesh cells on the roller surface, ensuring that only a certain amount of adhesive is left in each mesh cell. The sanitary napkin surface material passes through the coating pressure zone formed between the anilox roller 4 and the adhesive roller 17. Under the pressure provided by the adhesive roller 17, the hydrophilic agent in the mesh cells of the anilox roller 4 is evenly transferred to the surface of the surface layer, completing the hydrophilic treatment.

[0045] The power of the transmission gear set 6 is transmitted to the linkage gear set 14 through the meshing gear 15, driving all the stirring shafts 12 to rotate synchronously. The rubber scraper 13 on the stirring shaft 12 rotates accordingly, gently stirring the hydrophilic agent to prevent sedimentation and stratification, and scraping the inner wall of the immersion tank 7 to prevent the adhesive from forming a skin and inhibiting the generation of foam.

[0046] After production is completed, the operator starts the cleaning program. A motor installed on one side of the sliding plate 16 drives the upper adhesive roller 17 to rotate, so that the two adhesive rollers 17 rotate. At this time, the cleaning liquid spraying system 19 sprays cleaning liquid onto the surface of the adhesive roller 17. The adhesive roller 17 completes the cleaning as it rotates. Then the cleaning liquid is sprayed onto the surface of the anilox roller 4. As the anilox roller 4 rotates, the anilox roller 4 can be initially cleaned. The cleaning liquid is finally collected in the immersion tank 7. The immersion tank 7 is cleaned as the rubber scraper 13 rotates. Finally, the cleaning liquid is drained.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
