[0001] The present invention belongs to the technical field of diaper production equipment, and particularly relates to a manufacturing device and process for a comfortable, soft, bubble-waist diaper. Background Art

[0002] Currently, the conveying mechanism of existing diaper packaging machines stacks multiple diapers and then compresses them before feeding them into a packaging bag for packaging. This packaging method has low efficiency and requires manual participation during the packaging process, and cannot fully achieve automation. In view of this, this solution was developed. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a manufacturing device and process for a comfortable, soft, bubble-waist diaper, which can automatically package multiple diapers.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: a manufacturing device for a comfortable, soft, bubble-waist diaper, including a packaging device. The packaging device includes a first conveyor belt, a feeding pipe, a blocking component, two unwinding components, a side heat-sealing component, and a bottom heat-sealing and cutting component. The inlet of the feeding pipe is located at the output end of the first conveyor belt. The blocking component is used to block the diapers entering the feeding pipe from the first conveyor belt. The unwinding components are located on both sides of the lower end of the feeding pipe. The two unwinding components unwind the packaging film towards the lower end of the feeding pipe. The side heat-sealing component is used to heat-seal the two sides of the packaging film released by the two unwinding components. The side heat-sealing component includes two first driving bodies and two arc-shaped hot pressing plates. The arc-shaped hot pressing plates are connected to the output ends of the first driving bodies. The first driving bodies are located on both sides of the feeding pipe. The inner diameter of the arc-shaped hot pressing plates is the same as the outer diameter of the feeding pipe. The bottom heat-sealing and cutting component heat-seals the bottom of the two heat-sealed packaging films.

[0005] Further, the vertical cross-section of the arc-shaped hot pressing plate is U-shaped, and extension plates extending outward are formed on both sides of the opening of the arc-shaped hot pressing plate.

[0006] Further, the unwinding component includes an unwinding roller, two conveying rollers, and a plurality of guiding rollers. The two conveying rollers are arranged left and right and are located on the side of the feeding pipe. The distance between the two conveying rollers is less than the thickness of the packaging film. The packaging film is wound around the unwinding roller and passes through the plurality of guiding rollers and between the two conveying rollers in sequence.

[0007] Further, the peripheral surface of the feeding pipe has an insertion notch. The blocking component includes a second driving body and a blocking plate. The second driving body drives the blocking plate to insert into or extend out of the feeding pipe from the insertion notch.

[0008] Further, the back cover cutting assembly includes two third driving bodies, a hot pressing straight plate, and a cutting knife. The two third driving bodies are located below the blanking pipeline and are arranged oppositely. The hot pressing straight plate is connected to the output end of the third driving body. The cutting knife is fixedly connected to the middle of any one of the hot pressing straight plates. A receiving groove is formed on the surface of the other hot pressing straight plate, and the cutting knife is adapted to the receiving groove.

[0009] Further, the hot pressing straight plate includes an upper heat-sealing area and a lower heat-sealing area.

[0010] Further, the packaging equipment further includes a gluing assembly and a stamping machine. The gluing assembly is used to apply glue to the surface of the disposable diapers on the first conveyor belt. The output end of the stamping machine faces the blanking pipeline.

[0011] Further, the gluing assembly includes a glue roller, and the glue roller is located above the output end of the first conveyor belt.

[0012] A manufacturing process for a comfortable and soft bubble waist disposable diaper includes the following steps.

[0013] S1. Manufacture the disposable diaper.

[0014] S2. Stack the disposable diapers.

[0015] S3. Load the stacked disposable diapers into a three-side sealed packaging bag.

[0016] S4. Seal the opening of the three-side sealed packaging bag and form a new three-side sealed packaging bag for containing the next batch of disposable diapers.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The first conveyor belt of the present invention conveys the disposable diapers into the blanking pipeline. At this time, the blocking assembly in the blanking pipeline blocks the disposable diapers from falling out of the blanking pipeline until a certain number of disposable diaper assemblies are stacked. Then, the blocking assembly is removed, and the disposable diapers fall into the packaging bag that has been heat-sealed on three sides below. The packaging bag is unrolled by two unwinding assemblies. The side heat-sealing assembly seals the sides of the packaging films unwound by the two unwinding assemblies. The back cover cutting assembly heat-seals the bottom of the packaging film that has been sealed on two sides, thereby forming a three-side sealed packaging bag. Multiple disposable diapers fall out of the blanking pipeline and into the packaging bag. The packaging film continues to be unrolled downward. The back cover cutting assembly seals the upper opening of the three-side sealed packaging bag filled with disposable diapers and then cuts it off. While the packaged disposable diapers are removed, the back cover cutting assembly seals the bottom of the packaging film that has been sealed on two sides.

[0019] 2. The side heat-sealing assembly includes two first driving bodies and two arc-shaped hot pressing plates. When the two packaging films are within the heat-sealing range of the two arc-shaped hot pressing plates, the first driving bodies eject, and the two arc-shaped hot pressing plates press the two packaging films against the circumferential surface of the blanking pipe for side heat-sealing, forming a cylindrical packaging bag, which is convenient for holding the disposable diaper.

[0020] 3. Extension plates extending outward are formed on both sides of the opening of the arc-shaped hot pressing plate. The width of the packaging film is greater than the distance between the two extension plates, ensuring the accuracy of side heat-sealing of the two packaging films.

[0021] 4. The hot pressing straight plate includes an upper heat-sealing area and a lower heat-sealing area. The upper heat-sealing area and the lower heat-sealing area of one hot pressing straight plate are separated by a cutting knife, and the upper heat-sealing area and the lower heat-sealing area of the other hot pressing straight plate are separated by a receiving groove. The setting of the upper heat-sealing area and the lower heat-sealing area can heat-seal the packaging film on both side edges at the upper end while heat-sealing the three-side sealed packaging film to form a three-side heat-sealed packaging bag.

Detailed Embodiments

[0028] In order to make the above features and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0029] As Figures 1-5 shown, this embodiment provides a manufacturing device for a comfortable and soft bubble waist disposable diaper, including packaging equipment.Figure 5 The middle is the front view of the packaging bag 7, and the cross-sectional area is the heat-sealing area.

[0030] The packaging equipment includes a first conveyor belt 1, a blanking pipeline 2, a blocking assembly 3, two unwinding assemblies 4, a side heat-sealing assembly 5, and a bottom-sealing and cutting assembly 6.

[0031] The inlet of the blanking pipeline 2 is located at the output end of the first conveyor belt 1. The blanking pipeline 2 is provided with a square hole 21 that penetrates up and down. The horizontal projection area of the square block covers the maximum horizontal projection area of the diaper. The blanking pipeline 2 is columnar, and the peripheral surface of the blanking pipeline 2 has an insertion notch that communicates with the square hole 21.

[0032] The blocking assembly 3 is used to block the diaper that enters the blanking pipeline 2 from the first conveyor belt 1. The blocking assembly 3 includes a second driving body and a blocking plate. The second driving body drives to extend into or out of the blanking pipeline 2 from the insertion notch. The second driving body is a cylinder.

[0033] The unwinding assemblies 4 are located on both sides of the lower end of the blanking pipeline 2. The two unwinding assemblies 4 unwind the packaging film 71 towards the lower end of the blanking pipeline 2. The unwinding assembly 4 includes an unwinding roller 41, two conveying rollers 43, and a plurality of guiding rollers 42. The two conveying rollers 43 are arranged left and right and are located on the side of the blanking pipeline 2. The distance between the two conveying rollers 43 is less than the thickness of the packaging film 71. The packaging film 71 is wound around the unwinding roller 41. The packaging film 71 passes through a plurality of guiding rollers 42 and between the two conveying rollers 43 in sequence. The two conveying rollers 43 are used to pull the packaging film 71 on the unwinding roller 41 to move to both sides of the blanking pipeline 2. Under the action of gravity, the packaging film 71 located below the conveying roller 43 will move vertically downward (the position where the unwinding assembly 4 is located cannot be ventilated).

[0034] The side heat-sealing assembly 5 is used to heat-seal the two sides of the packaging film 71 released by the two unwinding assemblies 4. The side heat-sealing assembly 5 includes two first driving bodies 51 and two arc-shaped hot pressing plates 52. The arc-shaped hot pressing plates 52 are connected to the output ends of the first driving bodies 51. The first driving bodies 51 are located on both sides of the blanking pipeline 2. The first driving bodies 51 are oil cylinders. The inner diameter of the arc-shaped hot pressing plates 52 is the same as the outer diameter of the blanking pipeline 2. The vertical cross-section of the arc-shaped hot pressing plates 52 is U-shaped. Extension plates 521 extend outward on both sides of the opening of the arc-shaped hot pressing plates 52. The width of the packaging film 71 is greater than the distance between the two extension plates 521, ensuring the accuracy of the side heat-sealing of the two packaging films 71.

[0035] When the two packaging films 71 are within the heat-sealing range of the two arc-shaped hot pressing plates 52, the first driving bodies 51 eject, and the two arc-shaped hot pressing plates 52 press the two packaging films 71 against the peripheral surface of the blanking pipeline 2 for side heat-sealing, forming a cylindrical packaging bag 7, which is convenient for holding the diaper.

[0036] The bottom sealing and cutting assembly 6 heat-seals the bottoms of two heat-sealed packaging films 71. The bottom sealing and cutting assembly 6 includes two third driving bodies 61, a hot-pressing straight plate 62, and a cutting knife 63. The length of the cutting knife 63 is the same as that of the hot-pressing straight plate 62. The two third driving bodies 61 are located below the blanking pipeline 2 and are arranged oppositely. The third driving body 61 is an oil cylinder. The hot-pressing straight plate 62 is connected to the output end of the third driving body 61. The cutting knife 63 is fixedly connected to the middle of any one of the hot-pressing straight plates 62. A receiving groove 623 is formed on the surface of the other hot-pressing straight plate 62, and the cutting knife 63 is adapted to the receiving groove 623. The hot-pressing straight plate 62 includes an upper heat-sealing area 621 and a lower heat-sealing area. The upper heat-sealing area 621 and the lower heat-sealing area of one of the hot-pressing straight plates 62 are separated by the cutting knife 63, and the upper heat-sealing area 621 and the lower heat-sealing area of the other hot-pressing straight plate 62 are separated by the receiving groove 623. The setting of the upper heat-sealing area 621 and the lower heat-sealing area can heat-seal the upper two side-sealed packaging films 71 while heat-sealing the three-side-sealed packaging film 71 to form a three-side heat-sealed packaging bag 7.

[0037] In this solution, the first conveyor belt 1 conveys the disposable diapers into the blanking pipeline 2. At this time, the partition plate in the blanking pipeline 2 blocks the disposable diapers from falling out of the blanking pipeline 2. Until a certain number of disposable diaper components are stacked, the blocking plate is removed, and they fall into the packaging bag 7 that has been heat-sealed on three sides below. The packaging bag 7 is unrolled by two unwinding assemblies 4. The side heat-sealing assembly 5 seals the sides of the packaging films 71 unwound by the two unwinding assemblies 4. The bottom sealing and cutting assembly 6 heat-seals the bottom of the packaging film 71 that has been sealed on two sides, thereby forming a three-side heat-sealed packaging bag 7. Multiple disposable diapers fall out of the blanking pipeline 2 and fall into the packaging bag 7. The packaging film 71 continues to be unrolled downward. The lower sealing area of the hot-pressing straight plate 62 seals the upper opening of the three-side heat-sealed packaging bag 7 filled with disposable diapers. The cutting knife 63 cuts off the packaged disposable diaper packaging bag 7. While the packaged disposable diapers are removed, the upper sealing area of the hot-pressing straight plate 62 seals the bottom of the packaging film 71 that has been sealed on two sides.

[0038] Preferably, the packaging equipment further includes a gluing assembly (not shown in the figure) and a stamping machine (not shown in the figure). The gluing assembly is used to apply glue to the surface of the disposable diapers on the first conveyor belt 1. The gluing assembly includes an adhesive roller. The adhesive roller is located above the output end of the first conveyor belt 1. The glue on the adhesive roller is a pressure-sensitive adhesive or a glue with poor bonding strength. The output end of the stamping machine faces the blanking pipeline 2, and the output end of the stamping machine is coated with an anti-sticking coating. The disposable diapers on the first conveyor belt 1 enter the partition plate of the blanking pipeline 2 after passing through the adhesive roller and are stacked one by one. The stamping machine extends out to press the disposable diapers tightly, so that bonding occurs between multiple disposable diapers. When the partition plate is removed, they can enter the packaging bag 7 more neatly.

[0039] The present invention also provides a manufacturing process for a comfortable and soft bubble waist disposable diaper, including the following steps.

[0040] S1. Manufacture diapers using the diaper production equipment of the existing process.

[0041] S2. Stack the diapers. The first conveyor belt 1 conveys the diapers to the blanking pipe 2. The partition plate of the blocking assembly 3 in the blanking pipe 2 blocks the diapers from falling out of the blanking pipe 2 until a certain number of diaper assemblies are stacked.

[0042] S3. Load the stacked diapers into the three-side sealed packaging bag 7. The first driving body 51 ejects. The two arc-shaped hot pressing plates 52 push the two packaging films 71 against the circumferential surface of the blanking pipe 2 for side heat sealing to form a cylindrical packaging bag 7. The third driving body 61 ejects. The hot pressing straight plate 62 heat seals the lower opening of the cylindrical packaging bag 7 to form a three-side sealed packaging bag 7. The partition plate is withdrawn, and the diapers fall into the three-side sealed packaging bag 7.

[0043] S4. Seal the opening of the three-side sealed packaging bag 7 and form a new three-side sealed packaging bag 7 for containing the next batch of diapers. The two conveying rollers 43 continue to convey the packaging film 71. The two arc-shaped hot pressing plates 52 push the two packaging films 71 against the circumferential surface of the blanking pipe 2 for side heat sealing. The upper opening of the three-side sealed packaging bag 7 moves to the area of the hot pressing straight plate 62. The third driving body 61 ejects. The lower heat sealing area of the hot pressing straight plate 62 heat seals the upper opening of the cylindrical packaging bag 7. The cutting knife 63 cuts off the packaging bag 7 that has been filled with diapers, and the upper heat sealing area 621 of the hot pressing straight plate 62 heat seals the upper cylindrical packaging bag 7.
