Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, specifically to a diaper cutting device with a wrinkle-removing structure and its usage method. Background Technology

[0002] Disposable diapers are made of a multi-layered composite flexible material consisting of non-woven fabric, PE bottom film, elastic waistband and leg openings, and absorbent core. During high-speed continuous conveying, problems such as uneven tension, surface wrinkles, and edge curling are prone to occur. If the area to be cut is not wrinkled and flattened, it will directly lead to defects such as out-of-tolerance dimensions, rough edges, incomplete cuts, missed cuts, and contour deformation, and may even cause blade breakage, significantly increasing the product scrap rate.

[0003] Existing diaper cutting machines, with their core logic of "first shaping and clamping, then wrapping and cutting," effectively solve industry pain points such as elastic material rebound wrinkles and ultra-thin core crushing, and are widely used in diaper production lines. The core components of this type of machine include a shaping pressure plate, a lower support plate, and a wrapping cutter. The mating surfaces of the shaping pressure plate and the lower support plate must maintain extremely high flatness, and the fitting grooves on the lower support plate must precisely match the shaping pressure plate to achieve stable clamping, wrinkle removal, and shaping of the diaper strip, thereby ensuring cutting accuracy. However, in actual high-speed continuous production, absorbent resin particles from the multi-layer composite diaper strip detach. These tiny particles easily embed themselves in the grooves of the lower support plate and adhere to the mating surface of the shaping pressure plate, requiring machine shutdown for cleaning and reducing production efficiency. To address these technical shortcomings, a solution is proposed. Summary of the Invention

[0004] This invention provides a diaper cutting device and method with a wrinkle-removing structure, which solves the problem of absorbent resin particles getting stuck in the groove of the lower support plate and the bonding surface of the pressure plate, requiring machine shutdown for cleaning.

[0012] Furthermore, a synchronizing element is provided between the motor output end and the rotating shaft three.

[0013] Furthermore, a push plate is slidably connected inside the annular die, a connector is fixedly connected to the top of the push plate, a through hole is opened on the top of the pressure plate, and the connector is slidably connected inside the through hole.

[0014] A fixed plate is fixedly installed on the top of the support plate. A rotating shaft four is rotatably connected through the left and right sides of the fixed plate. A bevel gear five and a gear one are fixedly connected to both ends of the rotating shaft four, and the gear one meshes with the rack one.

[0015] Furthermore, a bevel gear four is fixedly connected to the rotating shaft three, and the bevel gear four meshes with the bevel gear five.

[0016] A method of using a diaper cutting device with a wrinkle-removing structure, applicable to a diaper cutting device with a wrinkle-removing structure:

[0017] Step 1: The diaper strip is moved to the underside of the ring die by the cutting machine. The motor drives the two mounting frames to rotate away from the ring die. During the rotation of the mounting frames, the spring restoring force causes the slider one to slide downward in the groove. The flattening roller presses the strip down onto the support plate. The two flattening rollers squeeze the strip downward and roll on the strip in opposite directions to spread the strip on the support plate. After the strip is spread, the motor stops running. The motor synchronously drives the lead screw to rotate. The threaded transmission between the lead screw and the second slider causes the second slider to move upward. The support plate moves upward with the second slider until it is on the same horizontal plane as the support plate.

[0018] Step 2: The electric actuator drives the pressure plate to move downwards. The annular die moves with the pressure plate towards the flattened strip and cuts the strip. At the same time, it passes through the gap between the support plate and the support plate. When the annular die enters the gap, gear 1 contacts rack 1. Gear 1 cannot rotate synchronously because shaft 3 is stationary. Rack 1 remains stationary during the downward movement of the annular die. The push plate remains stationary. The relative movement between the push plate and the annular die increases the distance between the bottom of the push plate and the bottom of the annular die. The increased distance provides space for the cut diaper, thus achieving the cutting.

[0019] Step 3: The motor rotates in the reverse direction, the flattening roller resets, and the pallet moves down synchronously. At the same time, the rotating shaft three rotates in the reverse direction, driving gear one to rotate. Gear one meshes with rack one, driving the mounting rail to move downward. The push plate moves downward with the mounting rail, pushing the diaper material inside the annular die onto the pallet. At the same time, it pushes the particles adsorbed on the inner wall of the annular die to below the support plate. During the downward movement of the pallet, gear two meshes with rack two, and the rotating shaft five rotates with gear two, causing the pallet to rotate towards the input end of the centrifugal fan vacuum cleaner, so that the cut material falls onto the surface of the conveyor belt for transmission. The particles generated during the cutting process are sucked away by the input end of the centrifugal fan vacuum cleaner.

[0020] Step 4: After cutting and blanking are completed, the electric push rod retracts and moves the annular die upward. During the upward movement, the annular die contacts the support plate, trapping the particles on the outer surface of the annular die below the support plate. At the same time, the motor rotates in the opposite direction until rack two moves above gear two. The structure is reset to the state before the next cutting.

[0021] The present invention has the following beneficial effects:

[0022] This diaper cutting device with a wrinkle-removing structure and its usage method lifts the tray by using the power to wrinkle and flatten the diaper material strip, allowing the tray to participate in the cutting operation. The tray supports the diapers cut from the material strip, and the separation of the tray from the support plate solves the problem of particles getting stuck in the grooves. Simultaneously, the flattened and fixed state allows the annular die to move relative to the push plate during the downward cutting process, providing space for the annular die's cutting and the cut diaper material. Then, the power generated by the rotation of the flattening roller and its separation from the material strip simultaneously moves the push plate downward, pushing the diaper material cut by the annular die onto the conveyor belt, and removing the annular die... The particles on the inner wall are scraped out and kept below the support plate. The support plate separates two spaces. Before cutting, the operation is above the support plate, and after cutting, the operation is below the support plate. When the support plate is below the support plate, it moves downward and rotates towards the inlet of the centrifugal fan dust collector. This ensures that the particles pushed out by the push plate and scraped off by the support plate are all processed below the support plate. As the push plate moves against the annular die, it generates negative pressure to blow the particles away from the annular die, isolating the particles and material strip generated during cutting. This also achieves simultaneous flattening, support, discharge, and unloading operations, ensuring continuous production.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The rack 39 is fixedly installed on the side of the mounting plate 38 near the gear 37. The rack 39 meshes with the gear 37.

[0043] A motor 12 is fixedly mounted on the top of the mounting bracket 4. A bevel gear 13 is fixedly connected to the output end of the motor 12. A rotating shaft 14 is rotatably connected to the top of the inner wall of the mounting bracket 4. There are two rotating shafts 14, which are symmetrically distributed front and back.

[0051] How to use the diaper cutting device with wrinkle-removing structure in this embodiment:

[0052] Step 1: The diaper strip is moved by the cutting machine 1 to below the annular die 7. The motor 12 drives the two mounting frames 18 to rotate away from the annular die 7. During the rotation of the mounting frames 18, the restoring force of the spring 22 drives the slider 21 to slide downward in the groove 19. The flattening roller 20 presses the strip down onto the support plate 31. The two flattening rollers 20 squeeze the strip downward and roll on the strip in opposite directions to spread the strip on the support plate 31. After the strip is spread, the motor 12 stops running. The motor 12 synchronously drives the lead screw 24 to rotate. The threaded transmission between the lead screw 24 and the slider 3501 causes the slider 3501 to move upward. The support plate 32 moves upward with the slider 3501 until it is on the same horizontal plane as the support plate 31.

[0053] The output end of motor 12 synchronously drives bevel gear 13 and the corresponding synchronous wheel in synchronizing element 23 to rotate. Bevel gear 13 meshes with bevel gear 15 at the opposite ends of two symmetrically distributed rotating shafts 14, driving the two rotating shafts 14 to rotate synchronously in opposite directions. Bevel gear 15 at the opposite ends of the two rotating shafts 14 then meshes with bevel gear 16 fixedly connected to the corresponding rotating shaft 17, driving the rotating shaft 17 to rotate on the top of the inner wall of the mounting frame 4. This enables motor 12 to drive the two mounting frames 18 to rotate away from the annular die 7.

[0054] The output end of motor 12 drives the rotating shaft 25 to rotate synchronously through the synchronous belt of the synchronous component 23 and the transmission cooperation of the two synchronous pulleys. The rotating shaft 25 drives the lead screw 24, which is fixedly connected to its bottom end and is on the same vertical line, to rotate synchronously. The lead screw 24 drives the slider 3501 to move upward along the lead screw 24 through the threaded transmission cooperation with the slider 3501. The slider 3501 drives the fixed component 34 to move upward synchronously through the fixed rod 35. Then, through the connecting block 33, which is rotatably connected to the fixed component 34, it drives the support plate 32 to move upward, so that the support plate 32 moves upward with the slider 3501.

[0055] Step 2: The electric push rod 5 drives the pressure plate 6 to move downwards. The annular die 7 moves with the pressure plate 6 towards the flattened material strip and cuts the material strip. At the same time, it passes through the gap between the support plate 32 and the support plate 31. When the annular die 7 enters the gap, gear 30 contacts rack 11. Gear 30 cannot rotate synchronously because the rotating shaft 25 is stationary. Rack 11 remains stationary during the downward movement of the annular die 7. The push plate 8 remains stationary. The relative movement between the push plate 8 and the annular die 7 increases the distance between the bottom of the push plate 8 and the bottom of the annular die 7. The increased distance provides space for the cut diaper, thus achieving the cutting.

[0056] As the annular die 7 moves downward with the pressure plate 6, the mounting rail 10, which is fixedly connected to the push plate 8 inside the annular die 7 via the bend-shaped connector 9 above the pressure plate 6, moves downward synchronously. This causes the rack 11 fixedly mounted on the inner wall of the mounting rail 10 to engage with the gear 30 fixed at the end of the rotating shaft 29 rotatably connected to the top fixed plate 28 of the support plate 31. At this time, since the motor 12 is in a stopped state, the rotating shaft 25, which is connected to the motor 12 via the synchronization component 23, remains stationary. The bevel gear 26 fixedly connected to the rotating shaft 25 also remains stationary. The bevel gear 27 meshing with the bevel gear 26 also remains stationary. Consequently, the rotating shaft 29 fixedly connected to the bevel gear 27 and the gear 30 fixedly connected to the rotating shaft 29 cannot rotate. This keeps the rack 11, mounting rail 10, connector 9, and push plate 8 all stationary, thus preventing the gear 30 from rotating synchronously due to the stationary state of the rotating shaft 25.

[0057] Step 3: The motor 12 rotates in the reverse direction, the flattening roller 20 resets, and the pallet 32 ​​moves down synchronously. At the same time, the shaft 25 rotates in the reverse direction, driving the gear 30 to rotate. The gear 30 meshes with the rack 11, driving the mounting rail 10 to move downward. The push plate 8 moves downward with the mounting rail 10, pushing the diaper material in the annular die 7 onto the pallet 32. At the same time, it pushes the particles adsorbed on the inner wall of the annular die 7 to below the support plate 31. During the downward movement of the pallet 32, the gear 37 meshes with the rack 39. The shaft 36 rotates with the gear 37, causing the pallet 32 ​​to rotate towards the input end of the centrifugal fan vacuum cleaner 3, so that the cut material falls onto the surface of the conveyor belt 2 for transmission. The particles generated during the cutting process are sucked away by the input end of the centrifugal fan vacuum cleaner 3.

[0058] After the cutting operation is completed, the motor 12 starts to rotate in reverse. On the one hand, through the transmission path of bevel gear 13, bevel gear 25, rotating shaft 14, bevel gear 316, and rotating shaft 27, it drives the mounting frame 18 to rotate in reverse and reset, so that the flattening roller 20 is reset synchronously with the mounting frame 18. On the other hand, through the synchronizing component 23, it drives the rotating shaft 325 to rotate in reverse. When the rotating shaft 325 rotates in reverse, it drives the lead screw 24 to rotate in reverse. Through the threaded transmission, it drives the slider 2501, the fixing rod 35, the fixing component 34, the connecting block 33, and the support plate 32 to move downward synchronously, so as to reset the flattening roller 20 and lower the support plate 32.

[0059] When the motor 12 rotates in the reverse direction, the bevel gear 26 on the shaft 25 rotates in the reverse direction with the shaft 25. Through the meshing transmission with the bevel gear 27, the shaft 29 rotates. The shaft 29 drives the gear 30 fixed at its end to rotate synchronously. The gear 30 drives the mounting rail 10 to move downward through the meshing transmission with the rack 11. Then, through the connecting piece 9, the push plate 8 moves downward synchronously. During the downward movement of the push plate 8, the diaper material cut in the annular die 7 is pushed onto the tray 32. At the same time, the cutting debris particles adsorbed on the inner wall of the annular die 7 are pushed below the support plate 31.

[0060] As the pallet 32 ​​moves downward with the slider 3501, the gear 37, which is fixedly connected to the rotating shaft 36 that is fixedly fixed to the left and right sides of the connecting block 33, moves downward synchronously with the pallet 32. During the downward movement of the gear 37, it meshes with the rack 39 fixedly installed on the bottom mounting plate 38 of the support plate 31, causing the gear 37 to rotate. The gear 37 drives the connecting block 33 to rotate within the fixing member 34 through the rotating shaft 36, thereby causing the pallet 32 ​​to rotate and tilt towards the input end of the centrifugal fan vacuum cleaner 3 on the cutting machine 1. This causes the cut material on the pallet 32 ​​to slide onto the surface of the conveyor belt 2 at the bottom of the inner wall of the cutting machine 1. The conveyor belt 2 completes the transfer of the cut material. At the same time, the debris generated during the cutting process is sucked away by the input end of the centrifugal fan vacuum cleaner 3, completing the finished product unloading and debris cleaning operations.

[0061] Step 4: After cutting and unloading, the electric push rod 5 retracts and moves the annular die 7 upward. During the upward movement, the annular die 7 contacts the support plate 31, trapping the particles on the outer surface of the annular die 7 below the support plate 31. At the same time, the motor 12 rotates in the opposite direction until the rack 2 39 moves above the gear 2 37, and the structure is reset to the state before the next cutting.

[0062] After the material feeding and cleaning operations are completed, the electric push rod 5 starts to retract, driving the pressure plate 6 and the annular die 7 to move upward and reset. During the upward movement of the annular die 7, it contacts the support plate 31, trapping the debris particles attached to the outer surface of the annular die 7 below the support plate 31, which are then sucked away by the input end of the centrifugal fan vacuum cleaner 3. At the same time, the motor 12 rotates in the opposite direction again until the rack 2 39 moves above the gear 2 37, so that all the structures of the device are reset to the initial state before cutting, and the next cutting operation can be carried out.

8. A method of using a diaper cutting device with a wrinkle-removing structure, applied to the diaper cutting device with a wrinkle-removing structure as described in any one of claims 1-7, characterized in that: Step 1: The diaper strip is moved to the underside of the ring die (7) by the cutting machine (1). The motor (12) drives the two mounting frames (18) to rotate away from the ring die (7). During the rotation of the mounting frames (18), the restoring force of the spring (22) drives the slider one (21) to slide downward in the groove (19). The flattening roller (20) presses the strip down towards the support plate (31). The two flattening rollers (20) squeeze the strip downward and roll on the strip in opposite directions to spread the strip on the support plate (31). After the strip is spread, the motor (12) stops running. The motor (12) drives the screw (24) to rotate synchronously. The threaded transmission between the screw (24) and the slider two (3501) causes the slider two (3501) to move upward. The support plate (32) moves upward with the slider two (3501) and is located on the same horizontal plane as the support plate (31). Step 2: The electric push rod (5) drives the pressure plate (6) to move downward. The ring die (7) moves with the pressure plate (6) to the flattened strip and cuts the strip. At the same time, it passes through the gap between the support plate (32) and the support plate (31). When the ring die (7) enters the gap, the gear 1 (30) contacts the rack 1 (11). The gear 1 (30) cannot rotate synchronously because the rotating shaft 3 (25) is stationary. The rack 1 (11) remains stationary during the downward movement of the ring die (7). The push plate (8) remains stationary. The relative movement between the push plate (8) and the ring die (7) increases the distance between the bottom of the push plate (8) and the bottom of the ring die (7). The increased distance provides space for the cut diaper, thus achieving the cutting. Step 3: The motor (12) rotates in the reverse direction, the flattening roller (20) resets, the pallet (32) moves down synchronously, and the shaft three (25) rotates in the reverse direction, driving the gear one (30) to rotate. The gear one (30) meshes with the rack one (11) to drive the mounting rail (10) to move down. The push plate (8) moves down with the mounting rail (10) and pushes the diaper material in the ring die (7) onto the pallet (32). At the same time, it pushes the particles adsorbed on the inner wall of the ring die (7) to the bottom of the support plate (31). During the downward movement of the pallet (32), the gear two (37) meshes with the rack two (39). The shaft five (36) rotates with the gear two (37) to make the pallet (32) rotate towards the input end of the centrifugal fan vacuum cleaner (3), so that the cut material falls onto the surface of the conveyor belt (2) for transmission. The particles generated during the cutting process are sucked away by the input end of the centrifugal fan vacuum cleaner (3). Step 4: After cutting and unloading, run the electric push rod (5) to retract and move the ring die (7) upward. During the upward movement, the ring die (7) contacts the support plate (31) and traps the particles on the outer surface of the ring die (7) below the support plate (31). At the same time, the motor (12) rotates in the opposite direction until the rack (39) moves above the gear (37). The structure is reset to the previous cutting position before the next cutting.
