Description

Technical Field

[0001] This utility model relates to the field of profile processing equipment technology, specifically to a high-speed slitting device for diaper production. Background Technology

[0002] Disposable diapers are disposable hygiene products designed specifically for infants, incontinent adults, or individuals with special medical needs. Through a multi-layered composite structure of functional materials, they achieve the core functions of rapid liquid absorption, keeping skin dry, and preventing leakage, thus possessing an increasingly broad market prospect. Disposable diapers are primarily produced using automated, assembly line methods. The production process can be divided into several steps: surface and bottom film fabrication, core molding, lamination, cutting and shaping, addition of elastic components, quality inspection, and packaging. Among these steps, the cutting and shaping process often employs a stamping structure to slit the prepared composite tape. This structure requires a cylinder to drive the cutter in a reciprocating motion, resulting in a slow cutting speed that is difficult to control precisely, easily leading to uneven cutting. A new type of device is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a high-speed slitting device for diaper production, comprising a base, a lifting mechanism in the middle of the base plate, an anvil connected to the output end of the lifting mechanism, a pressure-sensitive pad on the top surface of the anvil, the pressure-sensitive pad being electrically connected to the lifting mechanism, an anvil placed on the pressure-sensitive pad, a cutting mechanism above the anvil, a drive motor in the cutting mechanism being electrically connected to a speed measuring component, tensioning cylinders on both sides of the anvil, and steering cylinders on both sides of the top surface of the base plate, with a composite belt passing through the gaps between the cylinders.

[0004] Furthermore, the lifting mechanism includes a lifting motor, which is installed on the bottom surface of the seat plate. The output gear of the lifting motor meshes with the bottom gear of the lifting shaft. The lower section of the lifting shaft is rotatably connected to the middle of the seat plate through a bearing. The upper section of the lifting shaft is threadedly connected to a threaded sleeve. The flange of the threaded sleeve is embedded in the lifting hole opened on the bottom surface of the anvil and fixed with bolts. The lifting shaft passes through the lifting hole. Guide holes are opened on both sides of the bottom surface of the anvil. The guide holes are slidably connected to the vertical guide rod. The vertical guide rod is fixed on the top surface of the seat plate.

[0005] Furthermore, the cutting mechanism includes columns located on both sides of the base, with a cutting shaft rotatably connected between the two columns. The flange of the cutting shaft is bolted to the cutting cylinder. The cutting cylinder body is provided with several protruding rings along the rolling direction. One end of the cutting shaft is connected to a drive motor, which is mounted on the columns.

[0006] Furthermore, a support is provided on the top surface of the column, and a brush cylinder is rotatably connected between the supports. A brush is provided at the bottom of the brush cylinder, and the brush contacts the body of the cutting cylinder. The inner cavity of the brush cylinder is connected to the root of the brush through a capillary tube.

[0007] Furthermore, the speed measuring assembly includes a hinged arm mounted on the top surface of the anvil, with a probe hinged to the top of the hinged arm, the probe facing a counting point on a tension cylinder to one side.

[0008] Furthermore, the two ends of the tensioning cylinder are rotatably connected to the lifting seat, and the two sides of the lifting seat are connected to the adjusting bolts by fastening nuts. The heads of the adjusting bolts are vertically slidably connected to the convex grooves opened on the top surface of the anvil.

[0009] The beneficial effects of this invention are as follows: This invention utilizes the cooperation of a slitting cylinder and an anvil to perform high-speed rolling cuts on the composite tape passing through it, thereby achieving the slitting of the diaper's shape. During the slitting process, alcohol-soaked brushes inside the brush cylinder clean and disinfect the slitting cylinder; the speed measuring component can adjust the rotation speed of the drive motor in real time to ensure that the rolling speed is consistent with the traction speed of the composite tape; the pressure-sensitive pad can adjust the height of the anvil through a lifting mechanism to maintain a fixed cutting pressure.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 3 As shown, a high-speed slitting device for diaper production includes a base 1. A lifting motor 9 of a lifting mechanism is installed on the bottom surface of a seat plate 101 of the base 1. The output gear of the lifting motor 9 meshes with the bottom gear of a lifting shaft 10. The lower section of the lifting shaft 10 is rotatably connected to the middle of the seat plate 101 via a bearing. The upper section of the lifting shaft 10 is threadedly connected to a threaded sleeve 11. The flange of the threaded sleeve 11 is embedded in a lifting hole 201 opened on the bottom surface of an anvil 2 and fixed with bolts. The lifting shaft 10 passes through the lifting hole 201. Guide holes 202 are opened on both sides of the bottom surface of the anvil 2. The guide holes 202 are slidably connected to a vertical guide rod 12. The vertical guide rod 12 is fixed on the top surface of the seat plate 101. A pressure-sensitive pad 3 is laid on the top surface of the anvil 2. The pressure-sensitive pad 3 is electrically connected to the lifting motor 9. An anvil 4 is placed on the pressure-sensitive pad 3.

[0018] In this embodiment, a cutting cylinder mechanism is provided above the anvil 4. The cutting cylinder mechanism includes columns 13, which are located on both sides of the base 1. A cutting shaft 14 is rotatably connected between the two columns 13. The flange of the cutting shaft 14 is connected to the cutting cylinder 15 by bolts. The body of the cutting cylinder 15 is provided with several protruding rings 1501 along the rolling direction. One end of the cutting shaft 14 is connected to a drive motor 5, which is mounted on the column 13. The drive motor 5 is electrically connected to a speed measuring component. The speed measuring component includes a hinge arm 19, which is mounted on the top surface of the anvil 2. A probe 20 is hinged to the top of the hinge arm 19, and the probe 20 faces one side to the counting point 601 on the tension cylinder 6. A support 16 is provided on the top surface of the column 13. A brush cylinder 17 is rotatably connected between the supports 16. A brush 18 is provided at the bottom of the brush cylinder 17. The brush 18 contacts the body of the cutting cylinder 15. The inner cavity of the brush cylinder 17 is connected to the root of the brush 18 through a capillary tube.

[0019] In this embodiment, tensioning cylinders 6 are provided on both sides of the anvil 2. The two ends of the tensioning cylinders 6 are rotatably connected to the lifting seat 21. The two sides of the lifting seat 21 are connected to adjusting bolts 22 by fastening nuts. The heads of the adjusting bolts 22 are vertically slidably connected to the convex grooves 203 opened on the top surface of the anvil 2. The two sides of the top surface of the seat plate 101 are rotatably connected to the steering cylinders 7 by hinged seats. The composite belt 8 passes through the gaps between the cylinders.

[0020] The working principle of this utility model is as follows:

[0021] like Figure 1 As shown, the composite belt 8 prepared from the upstream production line passes under the right-side turning cylinder 7, then around the top of the two tensioning cylinders 6, and finally exits under the left-side turning cylinder 7 to the downstream traction device. When the traction device drives the composite belt 8 through the bottom of the slitting cylinder 15, the probe 20 obtains the forward speed of the composite belt 8 based on the counting point 601, thereby controlling the rotation speed of the drive motor 5 to keep the rolling cutting speed of the slitting cylinder 15 on the composite belt 8 consistent with the traction speed of the composite belt 8. During this process, the convex ring 1501 rolls and cuts the shape of the diaper on the surface of the composite belt 8. At the same time, the pressure-sensitive pad 3 senses the pressure of the slitting cylinder 15 on the anvil 4 in real time, thereby controlling the lifting motor 9 to precisely adjust the height of the anvil 2 to keep the rolling cutting pressure consistent. When the convex ring 1501 rotates to the brush 18, the brush 18, which is soaked in alcohol, disinfects and cleans it, thereby keeping the slitting cylinder 15 clean. This utility model has the characteristics of precision, high speed, and intelligence, and is suitable for the automated production of diapers, which can significantly improve the slitting speed of diapers.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
