Description

Technical Field

[0001] This utility model relates to the technical field of diaper production equipment, and specifically discloses an adhesive applicator for adult diaper production. Background Technology

[0002] Adult diapers are disposable paper care products that function similarly to baby diapers but are stronger. Their core structure typically includes a skin-friendly non-woven inner layer, an absorbent core layer, and a leak-proof bottom film. During the manufacturing process of adult diapers, an adhesive coating device is used to coat the diaper raw materials with adhesive in order to bond the various structures together.

[0003] Chinese patent CN216025883U discloses an easy-to-use adhesive applicator for diaper production, belonging to the field of diaper production technology. It includes a base, a support, a connecting rod, a guide roller, and a tension roller. The support is fixedly installed on the top of the base, the connecting rod is fixedly installed on the lower side of one side of the support, the guide roller is fixedly installed below the connecting rod, and the tension roller is fixedly installed on the side of the support near the guide roller. A uniform adhesive applicator and a roller brush cooling mechanism are respectively arranged below the support, as well as a fixing block, a V-groove, and a guide groove. This invention, by incorporating a glue storage tank, drive motor, stirring frame, discharge valve, support plate, support rod, electric push rod, fixing block, V-groove, and guide groove, can evenly apply glue to the raw materials of diapers. Furthermore, it can scrape off residual glue in the guide groove using a scraper, preventing residual glue from affecting the next batch of diapers, thus improving the quality and efficiency of diaper gluing. However, the aforementioned device lacks a glue heating function, which can easily cause glue to adhere to the inner walls of the glue storage tank and V-groove, clogging the glue outlet at the lower end of the V-groove. This affects the glue dispensing effect, increases the workload of cleaning these components, and leads to unnecessary glue waste. Therefore, to solve these problems, this invention proposes a glue application device for adult diaper production. Utility Model Content

[0004] The present invention aims to provide a gluing device for adult diaper production, which has the function of heating the glue liquid, thereby preventing the glue liquid from adhering to the inner wall of the inner liner of the glue storage tank and the inner wall of the glue leveling tank, preventing the glue liquid from blocking the second glue outlet tube, reducing glue liquid waste and the workload of users in cleaning the above-mentioned components.

[0005] This utility model is achieved through the following technical solution: A gluing device for adult diaper production includes a base, a guide roller at one upper end of the base, a gluing mechanism above the base, a tensioning and evenly distributing mechanism on one side of the gluing mechanism, the gluing mechanism including two support rollers, both ends of which are rotatably connected to mounting plates, a glue storage tank above the support rollers, the glue storage tank including an inner liner, a heating tube, and an outer shell, a spiral heating tube outside the inner liner, and an outer shell outside the heating tube, an evenly distributing groove below the glue storage tank, a plurality of second glue outlet tubes arranged in a linear array connected to the lower end of the evenly distributing groove, heating plates on both sides of the evenly distributing groove, and a tensioning and evenly distributing mechanism including a tension roller, both ends of which are rotatably connected to a first U-shaped frame, and a first telescopic rod connected to the lower part of the first U-shaped frame.

A sealing plate is connected to the upper end of the glue leveling tank, and the lower end of the first glue outlet tube passes through the interior of the sealing plate, so as to facilitate the discharge of glue liquid inside the inner liner into the interior of the glue leveling tank.

[0007] As a further feature of the above solution, a stirring rod is installed inside the inner liner. Both sides of the stirring rod slide against the inner wall of the inner liner, allowing the adhesive adhering to the inner wall of the inner liner to be scraped off during the rotation of the stirring rod. A top plate is installed at the upper end of the inner liner, which is detachably connected to the outer shell. The lower surface of the top plate is flush with the top surface of the inner liner. The positive and negative electrodes of the heating tube penetrate through the interior of the outer shell. A feed pipe is installed on one side above the top plate to facilitate the injection of adhesive into the inner liner. The upper end of the stirring rod penetrates through the interior of the top plate and is rotatably connected to the top plate. A motor is connected to the upper end of the stirring rod, which can drive the stirring rod to rotate, ensuring that the adhesive stored inside the inner liner is heated evenly.

[0008] As a further feature of the above solution, a first support is connected to the outer side of the outer shell, and the two ends of the glue-equalizing groove are respectively connected to the two sides of the first support, which can provide support for the glue storage tank and its connecting parts. The lower end of the second glue-dispensing tube is detachably connected to a cap, which can adjust the number and position of the second glue-dispensing tubes according to the width of the diaper raw material to prevent glue from dripping onto the base.

[0009] As a further provision of the above scheme, a limiting roller is provided on the side of the tension roller away from the support roller. Both ends of the limiting roller are rotatably connected to support seats. A coating roller is provided above the limiting roller. Both the limiting roller and the coating roller are made of transparent polyvinyl chloride or polytetrafluoroethylene, which can prevent the adhesive from adhering to the limiting roller and the coating roller, and make the coating roller spread the adhesive on the material evenly. A second U-shaped frame is rotatably connected to the outside of the coating roller. A second telescopic rod is connected to the upper middle part of the second U-shaped frame, which can adjust the distance between the coating roller and the limiting roller according to the thickness of the diaper material.

A spiral heating tube 222 is provided on the outside of the inner tank 221, and a shell 225 is provided on the outside of the heating tube 222. A glue-spreading groove 24 is provided below the glue storage tank 22. A plurality of second glue outlet tubes 242 arranged in a linear array are connected to the lower end of the glue-spreading groove 24. Heating plates 244 are provided on both sides of the glue-spreading groove 24. The tensioning glue-spreading mechanism 3 includes a tensioning roller 31. A first U-shaped frame 311 is rotatably connected to both ends of the tensioning roller 31. A first telescopic rod 32 is connected to the lower part of the first U-shaped frame 311.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, the lower middle part of the inner liner 221 is connected to a first glue outlet tube 223, one end of the first glue outlet tube 223 is connected to a valve 224, the upper end of the glue leveling tank 24 is connected to a sealing plate 241, and the lower end of the first glue outlet tube 223 passes through the interior of the sealing plate 241, so as to facilitate the discharge of glue liquid inside the inner liner 221 into the interior of the glue leveling tank 24.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the inner liner 221 is equipped with a stirring rod 229. Both sides of the stirring rod 229 slide against the inner wall of the inner liner 221, allowing it to scrape off the adhesive adhering to the inner wall of the inner liner 221 during rotation. The upper end of the inner liner 221 is equipped with a top plate 226, which is detachably connected to the outer shell 225. The lower surface of the top plate 226 is in contact with the top surface of the inner liner 221. The inner liner 221 is detachably connected to the outer shell 225. The positive and negative poles of the heating tube 222 penetrate through the interior of the outer shell 225. A feed pipe 227 is provided on one side above the top plate 226 to facilitate the injection of adhesive into the inner liner 221. The upper end of the stirring rod 229 penetrates through the interior of the top plate 226 and is rotatably connected to the top plate 226. The upper end of the stirring rod 229 is connected to a motor 228, which drives the stirring rod 229 to rotate, ensuring that the adhesive stored inside the inner liner 221 is heated evenly.

[0021] like Figure 1 , Figure 2 and Figure 6As shown, the outer side of the outer shell 225 is connected to the first support 23, and the two ends of the glue-equalizing groove 24 are respectively connected to the two sides of the first support 23, which can provide support for the glue storage tank 22 and its connecting parts. The lower end of the second glue dispensing tube 242 is detachably connected to the cover 243, which can adjust the number and position of the second glue dispensing tube 242 according to the width of the diaper raw material, so as to prevent glue from dripping onto the base 1.

[0022] like Figure 1 , Figure 2 and Figure 8 As shown, a limiting roller 33 is provided on the side of the tension roller 31 away from the support roller 21. Both ends of the limiting roller 33 are rotatably connected to support seats 331. A coating roller 34 is provided above the limiting roller 33. Both the limiting roller 33 and the coating roller 34 are made of transparent polyvinyl chloride or polytetrafluoroethylene, which can prevent the glue from adhering to the limiting roller 33 and the coating roller 34, so that the coating roller 34 can evenly apply the glue above the raw material. A second U-shaped frame 341 is rotatably connected to the outside of the coating roller 34. A second telescopic rod 35 is connected to the upper middle part of the second U-shaped frame 341, which can adjust the distance between the coating roller 34 and the limiting roller 33 according to the thickness of the diaper raw material. A second bracket 36 is connected to the outside of the second telescopic rod 35, which can provide support for the second telescopic rod 35 and its connecting parts.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a controller 4 is provided on one side above the base 1. The motor 228, heating tube 222, heating plate 244, first telescopic rod 32 and second telescopic rod 35 are all connected to the controller 4 through power lines and signal lines, so that the controller 4 can control the operation of the above components to ensure the effectiveness of the device.

[0024] The adhesive applicator for adult diaper production disclosed in this embodiment involves installing the diaper raw material to be coated and the existing post-coating processing device (not the focus of this application and therefore not shown in the figures) at both ends of the device before use. Sufficient adhesive is injected into the inner liner 221 through the feed pipe 227. The controller 4 is used to turn on the motor 228 and heating tube 222 to stir and heat the adhesive inside the inner liner 221. One end of the raw material to be coated is passed under the guide roller 11 and placed on the two support rollers 21. The cover 243 below the second adhesive outlet pipe 242 is removed according to the width of the diaper raw material and placed aside. The valve 224 is opened, allowing the adhesive inside the inner liner 221 to flow from the first adhesive outlet pipe 223 into the uniform adhesive tank 24. The speed of the first adhesive outlet pipe 223 is greater than the speed of the adhesive discharge from the multiple second adhesive outlet pipes 242. The adhesive in 24 flows evenly to different positions along the longitudinal direction of the diaper material through multiple second adhesive outlet tubes 242. Pulling the end of the diaper material, the end is pulled over the tension roller 31 and then passes between the limit roller 33 and the coating roller 34, connecting to the original coating post-processing device. This causes the original coating post-processing device to move the diaper material. The controller 4 is used to turn on the two heating plates 244, which heat the adhesive inside the adhesive tank 24. The controller 4 controls the extension of the second telescopic rod 35, which drives the coating roller 34 to move downward, so that the coating roller 34 contacts the diaper material and the adhesive above it, and the adhesive is evenly coated. In use, the controller 4 can control the extension and retraction of the first telescopic rod 32 to adjust the distance between the tension roller 31 and the base 1, thereby adjusting the distance between the highest point of the diaper material and the base 1, and thus adjusting the tension of the diaper material.

[0025] The controller 4, guide roller 11, support roller 21, mounting plate 211, glue storage tank 22, inner liner 221, heating tube 222, first glue outlet tube 223, valve 224, outer shell 225, top plate 226, feed pipe 227, motor 228, stirring rod 229, first bracket 23, glue even tank 24, sealing plate 241, second glue outlet tube 242, cover 243, heating plate 244, tension roller 31, first U-shaped frame 311, first telescopic rod 32, limiting roller 33, support seat 331, glue coating roller 34, second U-shaped frame 341, second telescopic rod 35, and second bracket 36 disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
