Technical Field

[0001] This utility model relates to the field of underwear production technology, and in particular to a reciprocating continuous automatic shaping device for disposable underwear. Background Technology

[0002] Disposable underwear is made of cotton or non-woven fabric. It is disposable after use, making it convenient for various occasions such as business trips and personal care. During the production process, disposable underwear is usually ironed and shaped to ensure comfort.

[0003] A search revealed a Chinese patent (CN207227741U) for a reciprocating continuous automatic shaping device for disposable underwear, belonging to the field of disposable underwear production technology. The device includes a shaping and drying chamber with a central steam ironing chamber and two hot air drying chambers. Shielding doors and a frame are located at both ends of the shaping and drying chamber. A sliding rail is mounted on the frame, and a continuously reciprocating shaping table is mounted on the sliding rail. Four ironing and shaping components are mounted on the continuously shaping table. Each ironing and shaping component has support rods arranged in a matrix, and each support rod has an underwear forming mold for easy positioning and shaping of disposable underwear.

[0004] However, the aforementioned reciprocating continuous automatic shaping equipment for disposable underwear has some shortcomings. Before ironing, it is inconvenient to flatten the disposable underwear, which causes the underwear to wrinkle and affect the ironing effect. Furthermore, the ironing device runs continuously throughout the entire shaping process, resulting in high energy consumption. Therefore, we propose a reciprocating continuous automatic shaping equipment for disposable underwear to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by proposing a reciprocating continuous automatic shaping device for disposable underwear.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reciprocating continuous automatic shaping device for disposable underwear includes a conveyor frame with a conveyor belt for conveying the disposable underwear. A gantry frame is fixedly connected to the top of the conveyor frame, and a drive box is fixedly connected to the top of the gantry frame. An installation plate is movably arranged inside the gantry frame, and an ironing plate is fixedly connected to the bottom of the installation plate. A reciprocating ironing and shaping mechanism is arranged between the installation plate and the drive box. Two cavities are formed in the installation plate, and two pressure rollers are rotatably connected to the bottom of the installation plate. A flattening mechanism is arranged between the two cavities and the two pressure rollers. A groove is formed on one inner wall of the right cavity. A switching mechanism is arranged between the groove, the installation plate, and the ironing plate.

[0008] A further feature of this invention is that the reciprocating ironing and shaping mechanism includes a servo motor fixedly connected to the rear side of the drive box and a large gear rotatably connected to the inner wall of the rear side of the drive box. A small gear is fixedly connected to the output shaft of the servo motor, and the small gear meshes with the large gear. A drive column is fixedly connected to the front side of the large gear. A lifting frame is slidably sleeved on the outer side of the drive column. Two connecting plates are fixedly connected to the bottom of the lifting frame, and the mounting plate is fixedly connected to the bottom of the two connecting plates.

[0009] A further feature of this invention is that two limiting rods are fixedly connected to the top inner wall and the bottom inner wall of the drive box, and the lifting frame is slidably sleeved on the outside of the two limiting rods.

[0010] A further feature of this invention is that a rectangular opening is provided on the side of the drive box that is close to the gantry frame, and two connecting plates are slidably fitted into the corresponding rectangular openings.

[0011] A further feature of this invention is that the flattening mechanism includes four torsion springs and a rotating shaft rotatably connected to the inner walls of the front and rear sides of the cavity. The front and rear ends of the rotating shaft are fixedly connected to rotating plates. The pressure roller is rotatably connected between the two rotating plates. The ends of the four torsion springs that are far apart from each other are respectively fixedly connected to the inner walls of the corresponding front and rear sides of the cavity. Two mounting rings are fixedly sleeved on the outer side of the rotating shaft. The ends of the four torsion springs that are close to each other are respectively fixedly connected to the corresponding mounting rings.

[0012] A further feature of this invention is that four torsion springs are respectively sleeved on the outer side of the corresponding rotating shaft, and a rubber roller is fixedly sleeved on the outer side of the pressure roller.

[0013] A further feature of this invention is that the switching mechanism includes a transmission shaft rotatably connected within a groove, a driving bevel gear fixedly sleeved on the outside of the left side of the transmission shaft, a rack slidably disposed within a mounting plate, and a push switch fixedly connected to the top of the mounting plate. One end of the transmission shaft is fixedly connected to a driven bevel gear, which meshes with the driving bevel gear. The other end of the transmission shaft is fixedly connected to a drive gear, which meshes with the rack. A pressure block is fixedly connected to the top of the rack, which cooperates with the push switch. The push switch is electrically connected to the ironing board.

[0014] A further feature of this invention is that two support plates are fixedly connected within the groove, and the transmission shaft is rotatably connected between the two support plates.

[0015] In this invention, a reciprocating continuous automatic shaping device for disposable underwear utilizes a servo motor to drive the rotation of a small gear. This small gear, in turn, drives the rotation of a large gear and a drive column. The drive column slides back and forth within the lifting frame, causing the lifting frame, two connecting plates, a mounting plate, and two pressure rollers to reciprocate up and down. As the device moves downwards, because the pressure rollers are lower than the ironing plate, they first contact the top of the disposable underwear. Under the downward pressure, the two pressure rollers roll outwards to shape the disposable underwear. The ironing plate is straightened and flattened. At the same time, the two pressure rollers drive the two rotating plates and the rotating shaft to deflect outward, causing the torsion spring to twist and store energy. The rotating shaft drives the rotation of the active bevel gear, which in turn drives the rotation of the driven bevel gear, the transmission shaft and the drive gear. The drive gear drives the rack to move downward, and the rack drives the pressure block to move downward. When the bottom of the ironing plate comes into contact with the top of the disposable underwear, the pressure block presses the switch. The switch controls the opening of the ironing plate to iron and shape the disposable underwear.

[0016] In this utility model, a reciprocating continuous automatic shaping device for disposable underwear is described. After ironing for a period of time, the servo motor is driven again. At this time, the drive column drives the connecting plate, the mounting plate and the two pressure rollers to move upward without squeezing the pressure rollers. At this time, under the torque of the torsion spring, the rotating shaft, the two rotating plates and the pressure rollers will deflect inward to reset. The reverse reset of the rotating shaft will drive the drive gear to rotate in the opposite direction to reset. The drive gear will drive the rack and the pressure block to move upward without pressing the button switch. At this time, the button switch controls the ironing plate to close and stops ironing, thus avoiding the waste of energy caused by keeping the ironing plate open during the reciprocating lifting process.

[0017] This utility model has a reasonable structural design. Before ironing and shaping, the disposable underwear can be straightened and flattened, which prevents the disposable underwear from affecting the ironing and shaping effect due to its own wrinkles. In the entire reciprocating continuous shaping process, the ironing board is only opened when it is in contact with the disposable underwear, avoiding the waste of energy caused by keeping the ironing board open all the time, and improving the service life of the ironing board.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-8 A reciprocating continuous automatic shaping device for disposable underwear includes a conveyor frame 1, a conveyor belt 3 for conveying disposable underwear on the conveyor frame 1, a gantry frame 5 fixedly connected to the top of the conveyor frame 1, a drive box 6 fixedly connected to the top of the gantry frame 5, an installation plate 9 movably arranged inside the gantry frame 5, an ironing plate 10 fixedly connected to the bottom of the installation plate 9, a reciprocating ironing and shaping mechanism between the installation plate 9 and the drive box 6, two cavities 24 opened in the installation plate 9, two pressure rollers 13 rotatably connected to the bottom of the installation plate 9, a flattening mechanism between the two cavities 24 and the two pressure rollers 13, a groove 4 opened on one inner wall of the right cavity 24, and a switching mechanism between the groove 4, the installation plate 9 and the ironing plate 10.

[0029] Specifically, the reciprocating ironing and shaping mechanism includes a servo motor 7 fixedly connected to the rear side of the drive box 6 and a large gear 20 rotatably connected to the inner wall of the rear side of the drive box 6. A small gear 19 is fixedly connected to the output shaft of the servo motor 7. The small gear 19 meshes with the large gear 20. A drive column 21 is fixedly connected to the front side of the large gear 20. A lifting frame 22 is slidably sleeved on the outer side of the drive column 21. Two connecting plates 8 are fixedly connected to the bottom of the lifting frame 22. A mounting plate 9 is fixedly connected to the bottom of the two connecting plates 8.

[0030] Using the above scheme: servo motor 7 is started, servo motor 7 drives the rotation of pinion 19, pinion 19 drives the rotation of large gear 20 and drive column 21, drive column 21 slides back and forth in the lifting frame 22, and drives the lifting frame 22, two connecting plates 8, mounting plate 9 and ironing plate 10 to move up and down, so as to continuously iron and shape disposable underwear.

[0031] Specifically, two limiting rods 23 are fixedly connected to the top inner wall and the bottom inner wall of the drive box 6. The lifting frame 22 is slidably sleeved on the outside of the two limiting rods 23. Rectangular openings are provided on the side of the drive box 6 and the gantry 5 that are close to each other. Two connecting plates 8 are slidably sleeved in the corresponding rectangular openings, which helps to guide the connecting plates 8 and the lifting frame 22, making their lifting more stable.

[0032] Specifically, the flattening mechanism includes four torsion springs 27 and a rotating shaft 11 rotatably connected to the front and rear inner walls of the cavity 24. The front and rear ends of the rotating shaft 11 are fixedly connected to rotating plates 12. The pressure roller 13 is rotatably connected between the two rotating plates 12. The ends of the four torsion springs 27 that are far apart from each other are respectively fixedly connected to the front and rear inner walls of the corresponding cavities 24. Two mounting rings 26 are fixedly sleeved on the outer side of the rotating shaft 11. The ends of the four torsion springs 27 that are close to each other are respectively fixedly connected to the corresponding mounting rings 26.

[0033] Using the above scheme: When moving downwards, because the pressure roller 13 is lower than the ironing board 10, the pressure roller 13 first comes into contact with the top of the disposable underwear. Under the downward pressure, the two pressure rollers 13 will roll outwards to straighten and flatten the disposable underwear. At the same time, the two pressure rollers 13 drive the two rotating plates 12 and the rotating shaft 11 to deflect outwards, causing the torsion spring 27 to twist and store energy. The rotating shaft 11 drives the rotation of the active bevel gear 25. The active bevel gear 25 drives the rotation of the driven bevel gear 17, the transmission shaft 14 and the drive gear 2. The drive gear 2 drives the rack 15 to move downwards. The rack 15 drives the pressure block 16 to move downwards. When the bottom of the ironing board 10 comes into contact with the top of the disposable underwear, the pressure block 16 presses the press switch 18. The press switch 18 controls the opening of the ironing board 10 to perform ironing and shaping work on the disposable underwear.

[0034] Specifically, four torsion springs 27 are respectively sleeved on the outer side of the corresponding rotating shaft 11, and a rubber roller is fixedly sleeved on the outer side of the pressure roller 13 to increase the friction between the pressure roller 13 and the disposable underwear, so that the pressure roller 13 can better straighten and flatten the disposable underwear, and at the same time guide the torsion springs 27.

[0035] Specifically, the switching mechanism includes a drive shaft 14 rotatably connected in the groove 4, a drive bevel gear 25 fixedly sleeved on the outside of the left-side drive shaft 11, a rack 15 slidably disposed in the mounting plate 9, and a push switch 18 fixedly connected to the top of the mounting plate 9. One end of the drive shaft 14 is fixedly connected to a driven bevel gear 17, and the drive bevel gear 25 meshes with the driven bevel gear 17. The other end of the drive shaft 14 is fixedly connected to a drive gear 2, which meshes with the rack 15. A pressure block 16 is fixedly connected to the top of the rack 15, and the pressure block 16 cooperates with the push switch 18. The push switch 18 is electrically connected to the ironing board 10.

[0036] Using the above scheme: After ironing for a period of time, the servo motor 7 is driven again. At this time, the drive column 21 drives the connecting plate 8, the mounting plate 9 and the two pressure rollers 13 to move upward without squeezing the pressure rollers 13. At this time, under the torque of the torsion spring 27, the rotating shaft 11, the two rotating plates 12 and the pressure rollers 13 will deflect inward to reset. The reverse reset of the rotating shaft 11 will drive the drive gear 2 to rotate in the opposite direction to reset. The drive gear 2 will drive the rack 15 and the pressure block 16 to move upward without pressing the press switch 18. At this time, the press switch 18 controls the ironing plate 10 to close and stop ironing, avoiding the waste of energy caused by keeping the ironing plate 10 open during the reciprocating lifting process.

[0037] Specifically, two support plates are fixedly connected inside the groove 4, and the drive shaft 14 is rotatably connected between the two support plates, which helps to support the drive shaft 14 and make its rotation more stable.

[0038] In this invention, disposable underwear is placed evenly spaced on the conveyor belt 3. When the conveyor belt 3 transports the disposable underwear to directly below the ironing board 10, the servo motor 7 is activated. The servo motor 7 drives the rotation of the pinion 19, which in turn drives the rotation of the gear 20 and the drive column 21. The drive column 21 slides back and forth within the lifting frame 22, causing the lifting frame 22, the two connecting plates 8, the mounting plate 9, and the two pressure rollers 13 to move up and down. When moving downwards, because the pressure rollers 13 are lower than the ironing board 10, they first come into contact with the top of the disposable underwear. Under the downward pressure, the two pressure rollers 13 will... The outward rolling action straightens and flattens the disposable underwear. At the same time, the two pressure rollers 13 drive the two rotating plates 12 and the rotating shaft 11 to deflect outward, causing the torsion spring 27 to twist and store energy. The rotating shaft 11 drives the rotation of the active bevel gear 25, which in turn drives the rotation of the driven bevel gear 17, the transmission shaft 14, and the drive gear 2. The drive gear 2 drives the rack 15 to move downward, and the rack 15 drives the pressure block 16 to move downward. When the bottom of the ironing plate 10 abuts against the top of the disposable underwear, the pressure block 16 presses the press switch 18. The press switch 18 controls the opening of the ironing plate 10 to perform ironing and shaping work on the disposable underwear.

[0039] After ironing for a period of time, the servo motor 7 is driven again. At this time, the drive column 21 drives the connecting plate 8, the mounting plate 9 and the two pressure rollers 13 to move upward without squeezing the pressure rollers 13. At this time, under the torque of the torsion spring 27, the rotating shaft 11, the two rotating plates 12 and the pressure rollers 13 will deflect inward to reset. The reverse reset of the rotating shaft 11 will drive the drive gear 2 to rotate in the opposite direction to reset. The drive gear 2 will drive the rack 15 and the pressure block 16 to move upward without pressing the press switch 18. At this time, the press switch 18 controls the ironing plate 10 to close and stop ironing, avoiding the waste of energy caused by keeping the ironing plate 10 open during the reciprocating lifting process. In addition, during the upward movement, the conveyor belt 3 can put the next disposable underwear conveyor belt below the ironing plate 10, so that the next disposable underwear can continue to be ironed and shaped.
