Description

Technical Field

[0001] This utility model belongs to the technical field of roller die-cutting equipment, and relates to a roller die-cutting machine for adult diapers with one-axis double cutting. Background Technology

[0002] Existing adult diaper roller die-cutting machines include a support frame and an upper roller and a lower roller mounted on the support frame. The outer surface of the upper roller is provided with a cutting edge, and the upper roller is also called a cutting roller. The outer surface of the lower roller is smooth, and the lower roller is also called a bottom roller. For example, a diaper core roller cutting device is disclosed in Chinese patent document [publication number: CN104097226A].

[0003] Existing adult diapers come in different sizes, typically small, medium, large, and extra-large. The demand for each size varies, so factories often produce different sizes on the same production line. Generally, larger diapers require larger diameter rollers, while smaller diapers require smaller diameter rollers. Currently, each size typically has its own dedicated die-cutting machine. Changing the production of a different size often requires a different die-cutting machine, necessitating multiple machines for the factory and resulting in high equipment procurement costs. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a single-axis double-cut adult diaper roller die-cutting machine, which solves the technical problem of how to reduce equipment procurement costs.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A single-axis, double-cut adult diaper roller die-cutting machine includes a support frame, an upper roller shaft, a lower roller shaft, and upper and lower rollers, both cylindrical in shape. The support frame has two opposing vertical walls. A blade is provided on the outer circumferential surface of the upper roller. The upper roller is composed of several upper cylindrical segments with arc-shaped cross-sections arranged sequentially along the circumference, and the lower roller is composed of several lower cylindrical segments with arc-shaped cross-sections arranged sequentially along the circumference. The upper cylindrical segments are detachably and fixedly connected to the outer circumferential surface of the upper roller shaft, and the lower cylindrical segments are detachably and fixedly connected to the outer circumferential surface of the lower roller shaft. Each of the two vertical walls has vertically arranged grooves, each groove containing an upper sliding plate and a lower sliding plate located below the upper sliding plate. Several detachable clamping plates are fixedly connected to each of the two vertical walls, clamping and fixing the upper and lower sliding plates to the two vertical walls. Both ends of the upper roller shaft pass through two upper sliding plates, and both ends of the lower roller shaft pass through two lower sliding plates.

[0007] Different product models correspond to upper and lower rollers with different outer diameters. For example, if a die-cutting machine produces two product models, it prepares two interchangeable upper rollers and two interchangeable lower rollers. The two upper rollers are cylindrical with the same inner diameter but different outer diameters, and the two lower rollers are cylindrical with the same inner diameter but different outer diameters. Since the upper and lower slides are set in a groove and clamped to the wall, the relative positions of the upper and lower slides can be changed to accommodate variations in the center distance between the upper and lower rollers when using rollers with different outer diameters. During production, the corresponding upper and lower rollers are fixedly connected to the upper and lower roller shafts, respectively. When a different model needs to be produced (i.e., during a line change), the clamping plates are released from the upper and lower sliding plates, allowing them to be removed from the chute. The upper and lower roller shafts are then removed along with the sliding plates. The upper roller is then detached from the upper roller shaft, and another upper roller is installed as a replacement. Similarly, the lower roller is detached from the lower roller shaft, and another lower roller is installed as a replacement. Finally, the upper and lower sliding plates are reinstalled into the chute and clamped to the wall using the clamping plates. This allows for the production of two different diaper models on a single die-cutting machine. The two upper and two lower rollers are interchangeable, achieving dual-cutting functionality on a single shaft. This eliminates the need for two separate die-cutting machines and avoids the need to replace the upper and lower roller shafts, thus reducing equipment procurement costs.

[0008] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, both the upper slide plate and the lower slide plate are fixed with lifting screws. Lifting ropes can be installed on these screws, facilitating the lifting of the upper slide plate and upper roller shaft, and the lower slide plate and lower roller shaft from the support for removal and placement, thus simplifying line changes.

[0009] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, the clamping plate is fixedly connected to the vertical wall by screws. This allows for easy release of the upper and lower sliding plates by loosening the screws, and for re-fixing them by tightening the screws, facilitating line changes.

[0010] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, the top of the support frame has a detachable top cover plate, and the bottom of the support frame has a base. Both the top cover plate and the base are fixedly connected between two vertical walls. The top cover plate and the base can increase the structural stability of the support frame, making the die-cutting machine work stably. The top cover plate is detachable, so when it is necessary to change the production model, the top cover plate can be removed first, and then the upper roller shaft and the lower roller shaft can be removed, which facilitates the disassembly of the upper roller shaft and the lower roller shaft.

[0011] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, a lifting ring is fixedly connected to the top cover plate. A lifting rope can be installed on the lifting ring, facilitating the lifting and removal of the top cover plate from the support by the crane, and also facilitating line changes.

[0012] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, two cylinders are fixed on the top cover plate. The piston rods of the two cylinders pass through the top cover plate and abut against the top surfaces of the two upper slide plates respectively. The two cylinders can exert downward pressure on the two upper slide plates, preventing the upper roller from vibrating upward during the operation of the die-cutting machine.

[0013] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, the upper roller shaft has an upper mounting section connected to the upper roller. Upper roller pillows are respectively fitted onto both ends of the upper mounting section on the upper roller shaft. The lower roller shaft has a lower mounting section connected to the lower roller. Lower roller pillows are respectively fitted onto both ends of the lower mounting section on the lower roller shaft. The outer circumferential surfaces of the upper and lower roller pillows abut against each other. This abutment between the outer circumferential surfaces of the upper and lower roller pillows protects the cutting edge, preventing it from colliding with the lower roller and ensuring the cutting performance of the cutting edge.

[0014] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, both the outer circumferential surfaces of the upper and lower rollers are conical surfaces. The smaller end of the upper roller faces the upper mounting section, and the larger end of the lower roller faces the lower mounting section. This allows for adjustment of the distance between the blade and the outer circumferential surface of the lower roller when wear occurs on either the upper or lower roller, reducing the likelihood of the blade colliding with the lower roller.

[0015] In the aforementioned single-axis double-cut adult diaper roller die-cutting machine, a counter is fixedly connected to the sliding plate, and the counter is set corresponding to the lower roller shaft. Generally, one rotation of the upper or lower roller shaft is enough to cut and form one diaper. The counter can record the number of rotations of the lower roller shaft, thus facilitating the recording of the number of diapers produced and aiding in production management.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The upper roller consists of several upper cylindrical segments with arc-shaped cross-sections arranged circumferentially, and the lower roller consists of several lower cylindrical segments with arc-shaped cross-sections arranged circumferentially. The upper cylindrical segments are detachably and fixedly connected to the outer circumferential surface of the upper roller shaft, and the lower cylindrical segments are detachably and fixedly connected to the outer circumferential surface of the lower roller shaft. A slide groove and a clamping plate are provided on the support. An upper sliding plate and a lower sliding plate are installed in the slide groove. The upper sliding plate is connected to the upper roller shaft, and the lower sliding plate is connected to the lower roller shaft. The relative positions of the upper and lower sliding plates in the slide groove can be changed. Two interchangeable upper rollers and two interchangeable lower rollers are prepared. The two upper rollers are cylindrical with the same inner diameter but different outer diameters, and the two lower rollers are cylindrical with the same inner diameter but different outer diameters, corresponding to two product models. This allows for the production of two models of diapers in one die-cutting machine. By replacing the two upper rollers and two lower rollers, a dual-cutting function on a single shaft is achieved, eliminating the need for two die-cutting machines and the need to replace the upper and lower roller shafts, thus reducing equipment procurement costs.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figure 1 and Figure 2 As shown, a single-axis double-cut adult diaper roller die-cutting machine includes a support 1. The support 1 has two opposing vertical walls 1a, each with a vertically arranged groove 1a1. Removable clamping plates 1e are fixedly connected to each of the two vertical walls 1a. Clamping plates 1e are fixedly connected to the inner and outer surfaces of the vertical walls 1a on both sides of the groove 1a1. The clamping plates 1e are strip-shaped, and each vertical wall 1a has six or four clamping plates 1e. When there are six clamping plates 1e on one vertical wall 1a, two clamping plates 1e can be installed on each side of the groove 1a1 on the inner side of the vertical wall 1a. The clamping plates 1e are fixedly connected to the vertical walls 1a by screws, with several screws arranged vertically in sequence. The top of the support 1 has a removable top cover plate 1b, and the bottom of the support 1 has a base 1c. A positioning sleeve 1c1 is provided on the bottom surface of the base 1c for elevating the base 1c. The top cover plate 1b and the base 1c are both fixedly connected between two vertical walls 1a. An intermediate plate 1d is also fixed between the vertical walls 1a, located between the base 1c and the top cover plate 1b. A clearance groove is formed on the bottom surface of the center of the base 1c, extending through the base 1c from left to right. Corresponding slots are provided on the vertical walls 1a. The clearance grooves and slots facilitate the insertion of forklifts or forks, thus facilitating the transport of the die-cutting machine to the line-changing station for line-changing operations. An outer cover 1f is also fixed to the outer side of the vertical walls 1a. Lifting rings 1b1 are fixedly connected to the top cover plate 1b, positioned at the four corners of the top cover plate 1b. Two cylinders 2 are fixed to the top cover plate 1b, with their piston rods passing through the top cover plate 1b and inserting into the sliding grooves 1a1 respectively.

[0031] like Figure 3 , Figure 4 and Figure 5As shown, the single-axis double-cut adult diaper roller die-cutting machine also includes an upper roller shaft 4 and a lower roller shaft 5, with an intermediate plate 1d located between the upper roller shaft 4 and the lower roller shaft 5. Each chute 1a1 is equipped with an upper slide plate 6 and a lower slide plate 7, with the lower slide plate 7 located below the upper slide plate 6. The upper slide plate 6 and the lower slide plate 7 are clamped between two clamping plates 1e, and the clamping plates 1e can clamp and fix the upper slide plate 6 and the lower slide plate 7 to the two vertical walls 1a. The piston rods of the two cylinders 2 pass through the top cover plate 1b and abut against the top surfaces of the two upper slide plates 6 respectively. The two ends of the upper roller shaft 4 are respectively mounted on the upper slide plate 6, and the two ends of the lower roller shaft 5 are respectively mounted on the lower slide plate 7. A bearing 14 is provided between the upper roller shaft 4 and the upper slide plate 6, and a bearing 14 is also provided between the lower roller shaft 5 and the lower slide plate 7. The two ends of the bearing 14 are equipped with bearing 14 spacers, dust covers, and fixing sleeves, etc. Both the upper slide plate 6 and the lower slide plate 7 are fixed with lifting screws 15, which are located on the outer side of the upper slide plate 6 and the lower slide plate 7. A counter 3 is fixed and connected to the lower slide plate 7, and the counter 3 is set corresponding to the lower roller shaft 5. The counter 3 is located on the outer side of the lower slide plate 7. The counter 3 is fixed to the lower slide plate 7 by screws and can be removed.

[0032] like Figures 6-9 As shown, the single-axis double-cut adult diaper roller die-cutting machine also includes two interchangeable upper rollers 8 and two interchangeable lower rollers 9. The two upper rollers 8 are cylindrical with the same inner diameter but different outer diameters, and the two lower rollers 9 are cylindrical with the same inner diameter but different outer diameters. Blades 8b are provided on the outer circumferential surface of the upper rollers 8. Each upper roller 8 consists of several upper roller segments 8a with arc-shaped cross-sections arranged sequentially along the circumference, and each lower roller 9 consists of several lower roller segments 9a with arc-shaped cross-sections arranged sequentially along the circumference. Five to eight upper roller segments 8a and five to eight lower roller segments 9a can be provided, with the number of upper roller segments 8a being the same as the number of lower roller segments 9a. The gap error at the connection point of the blade edges 8b of the upper roller 8 is within 0.002mm-0.003mm. Each upper roller 8 can be detachably and fixedly connected to the outer circumferential surface of the upper roller shaft 4, and each lower roller 9 can be detachably and fixedly connected to the outer circumferential surface of the lower roller shaft 5. Figure 10As shown, the upper roller shaft 4 has an upper mounting section 4a connected to the upper roller 8, and the lower roller shaft 5 has a lower mounting section 5a connected to the lower roller 9. The inner diameter of the two upper rollers 8 is equal to the outer diameter of the upper mounting section 4a, and the inner diameter of the two lower rollers 9 is equal to the outer diameter of the lower mounting section 5a. The outer diameter of the upper mounting section 4a is equal to the outer diameter of the lower mounting section 5a, and the corresponding upper rollers 8 and lower rollers 9 have the same outer diameter. Bolt connection holes are provided at the four corners and center of the upper roller segment 8a and the lower roller segment 9a, avoiding the position of the blade 8b. Bolt thread holes corresponding to the bolt connection holes are provided on the upper mounting section 4a and the lower mounting section 5a. The upper roller segment 8a and the lower roller segment 9a are fixedly connected to the upper roller shaft 4 and the lower roller shaft 5 respectively by bolts. In order to facilitate the disassembly and assembly of the upper roller segment 8a and the lower roller segment 9a, two extraction holes are also provided on the upper roller segment 8a and the lower roller segment 9a, and the extraction holes need to be set to avoid the blade 8b. The extraction hole is a threaded hole, and the lifting ring is connected to the upper cylinder segment 8a and the lower cylinder segment 9a through the threaded hole. After disassembly and assembly, the lifting ring is removed. Upper roller pillows 10 are respectively fitted on both ends of the upper roller shaft 4 at the upper mounting section 4a, and lower roller pillows 11 are respectively fitted on both ends of the lower roller shaft 5 at the lower mounting section 5a. Two sets of upper roller pillows 10 are provided, and the two sets of upper roller pillows 10 are interchangeable, with two upper roller pillows 10 forming one set. Two sets of lower roller pillows 11 are also provided, and the two sets of lower roller pillows 11 are interchangeable, with two lower roller pillows 11 forming one set. The two sets of upper roller pillows 10 are respectively set corresponding to the two upper rollers 8, and the two sets of lower roller pillows 11 are respectively set corresponding to the two lower rollers 9. The outer circumferential surfaces of the upper roller pillow 10 and the lower roller pillow 11 abut against each other. Both outer circumferential surfaces of the upper roller pillow 10 and the lower roller pillow 11 are conical surfaces. The small end of the upper roller pillow 10 faces the upper mounting section 4a, and the large end of the lower roller pillow 11 faces the lower mounting section 5a. The blade 8b protrudes slightly from the outer circumferential surface of the roller pillow by 0.12mm-0.15mm. The upper roller pillow 10 and the upper roller shaft 4 have a small interference fit. At the same time, the two ends of the upper roller shaft 4 are threaded with a first large nut 12 that abuts against the upper roller pillow 10. When the first large nut 12 rotates, it can push the upper roller pillow 10 to move, thereby adjusting the gap between the lower roller 9 and the lower roller 9 using the conical surface. The lower roller pillow 11 and the lower roller shaft 5 have a small interference fit. At the same time, the two ends of the lower roller shaft 5 are threaded with a second large nut 13 that abuts against the lower roller pillow 11. The upper roller pillow 10 and lower roller pillow 11 can be disassembled using an air punch. Air punch holes are provided in the upper mounting section 4a and the lower mounting section 5a. Compressed gas acts on the inner end faces of the upper roller pillow 10 and lower roller pillow 11 through the air punch holes, causing the upper roller pillow 10 and lower roller pillow 11 to come out. Alternatively, a hydraulic puller can be used to pull out the upper roller pillow 10 and lower roller pillow 11; or they can be pulled out after auxiliary heating.

[0033] During production, the upper roller 8 and lower roller 9 of the corresponding model are fixedly connected to the upper roller shaft 4 and lower roller shaft 5, respectively. When it is necessary to change the production model, i.e., when changing production lines, first transport the die-cutting machine to the line change station, then remove the top cover plate 1b, loosen the screws, release the clamping and fixing state of the clamping plate 1e on the upper slide plate 6 and lower slide plate 7, and then remove the upper slide plate 6 and lower slide plate 7 from the slide groove 1a1. The upper roller shaft 4 and lower roller shaft 5 are removed together with the upper slide plate 6 and lower slide plate 7. Then, remove the upper roller 8 from the upper roller shaft 4, and then remove the upper slide plate 6 and upper roller rest 10. After replacing it with another set of upper roller rest 10, reinstall the upper slide plate 6 onto the upper roller shaft 4, and then... One upper roller 8 is replaced and installed on the upper roller shaft 4; the lower roller 9 is removed from the lower roller shaft 5, and then the lower slide plate 7 and lower roller pillow 11 are removed. After replacing them with another set of lower roller pillows 11, the lower slide plate 7 is reinstalled on the lower roller shaft 5. Then, another lower roller 9 is replaced and installed on the lower roller shaft 5. After that, the upper slide plate 6 and lower slide plate 7 are reinstalled in the slide groove 1a1, and the screws are tightened to clamp and fix the upper slide plate 6 and lower slide plate 7 in place with the clamping plate 1e. Then, the top cover plate 1b is re-fixed to the vertical wall 1a, and finally, the die-cutting machine is sent back to the production line. In this way, two models of diapers can be produced in one die-cutting machine. By replacing the two upper rollers 8 and the two lower rollers 9, the dual-cutting function on one shaft is achieved, eliminating the need for two die-cutting machines and eliminating the need to replace the upper roller shaft 4 and lower roller shaft 5, thus reducing equipment procurement costs.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
