Description

Technical Field

[0001] This utility model relates to the field of diaper production, specifically a flattening device for diaper production. Background Technology

[0002] Disposable diapers are single-use products that can be discarded after use. They are made of materials such as non-woven fabric, toilet paper, fluff pulp, superabsorbent polymer, PE film, and elastic bands. Disposable diapers mainly consist of a top layer, an absorbent layer, and a bottom layer. During the production of disposable diapers, these three layers are fed into a flattening machine in a top-to-bottom arrangement for lamination, followed by a series of processes such as sterilization before packaging.

[0003] Patent application CN202323123847.2 discloses a flattening device for diaper production, including: a base box, a conveyor, a flattening roller, a drive assembly, a height adjustment assembly, and a pressure roller device. The conveyor is installed on the base box. During rolling and flattening, the device can limit the movement of the pressure roller body, making the conveying of each layer of fabric of the diaper more flat and the rolling more flat, reducing the likelihood of misalignment, effectively improving the production quality of diapers, and making it more practical.

[0004] However, in practical applications, traditional diaper raw materials are usually flattened directly by pressure rollers, which lacks tension on the fabric. After flattening, the fabric is prone to loosening and wrinkles, affecting subsequent diaper processing.

[0005] For example, when flattening the fabric of a diaper, the fabric is fed into a pressure roller to press and flatten it. However, the flattened fabric is still prone to loosening, which can cause wrinkles, reduce the quality of flattening, and affect the processing of the diaper. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a flattening device for diaper production. This device addresses the current lack of tensioning treatment for diaper fabric, which leads to fabric loosening after flattening, causing wrinkles and affecting subsequent diaper processing.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a leveling device for diaper production is designed, including a workbench, support columns are fixed at the four corners of the bottom of the workbench, fixed plates are fixed at the four corners of the top of the workbench, guide rollers are fixed on opposite sides of the two fixed plates, a mounting frame is fixed on the top of the workbench, a leveling roller is rotatably inserted through the top between the two inner sides of the mounting frame, a tensioning mechanism is connected inside the mounting frame, and a scraping mechanism is connected to the top edge of the workbench.

[0008] In this solution, the tensioning mechanism is used to clamp and squeeze the fabric with the pressure roller and the flattening roller, which avoids misalignment of multiple layers of fabric and can also tension the fabric to prevent it from loosening after flattening, thus preventing wrinkles from recurring and affecting subsequent processing. The flattening mechanism can be used to pre-flatten the fabric and remove the lint on the fabric surface, ensuring that the fabric is clean.

[0009] Preferably, the tensioning mechanism includes limiting rods that slide through the four corners of the top of the mounting frame. A mounting plate is fixed to the bottom end of the limiting rods. A rotating frame is fixed to the top center of the mounting plate. Pressure rollers rotate between the two inner sides of the rotating frame. A first connecting seat is symmetrically fixed to the bottom of the mounting plate. A connecting rod rotates inside the first connecting seat. A sliding rod is symmetrically fixed to the bottom between the two inner sides of the mounting frame. A second connecting seat slides symmetrically on the outer side of the sliding rod. A connecting shaft is fixed to the bottom center of the second connecting seat. A servo motor is fixed to the top center of the worktable. A turntable is fixed to the end of the output shaft of the servo motor. A vortex groove is symmetrically formed at the top center of the turntable.

[0010] In practical applications, the servo motor is started, driving the turntable to rotate, which in turn rotates the vortex groove. This causes the connecting shaft to move inside the vortex groove, which in turn causes the two connecting shafts to move the second connecting seat. The second connecting seat gradually moves away from the outside of the slide rod, causing the connecting rod to deflect vertically. This causes the first connecting seat to lift the mounting plate, which in turn lifts the pressure roller, thus tightening the fabric. At the same time, the pressure roller and the flattening roller clamp the fabric, preventing misalignment of multiple layers of fabric. This tensioning of the fabric prevents it from loosening after flattening, thus preventing wrinkles from forming again and avoiding affecting the subsequent processing of diapers.

[0011] Preferably, a baffle is fixed to the top of the limiting rod, and the leveling roller is opposite to the pressure roller.

[0012] In practical applications, when the pressure roller rises, it clamps the fabric between the pressure roller and the leveling roller to prevent the fabric from being misaligned during leveling.

[0013] Preferably, the bottom end of the connecting rod rotates inside the second connecting seat.

[0014] In practical applications, when the second connecting seats move away from each other, the connecting rod is driven to deflect vertically in the opposite direction, thereby causing the first connecting seat to rise, which in turn drives the pressure roller to rise and tighten the fabric.

[0015] Preferably, the connecting shaft is connected to the inside of the vortex groove.

[0016] In practical applications, when the turntable rotates, it drives the vortex groove to rotate, thereby causing the connecting shaft to move inside the vortex groove, making the two connecting shafts move away from or closer to each other, which facilitates the movement of the second connecting seat.

[0017] Preferably, the leveling mechanism includes connecting rods symmetrically fixed to the top edge of the workbench, mounting frames fixed to the top ends of the two connecting rods, rotating shafts symmetrically extending through both sides of the mounting frames, scrapers fixed to the opposite ends of the two rotating shafts, connecting rings fixed to the outer edges of the rotating shafts, and torsion springs fixed to one side of the connecting rings.

[0018] In practical applications, the fabric is passed between two scrapers, causing the scrapers to deflect and the rotating shaft to deflect, which in turn causes the connecting ring to deflect, deforming the torsion spring. The reaction force of the torsion spring then resets the rotating shaft, allowing the scrapers to adhere tightly to the surface of the fabric. As the fabric moves, the scrapers perform initial scraping of the fabric surface, thus achieving preliminary smoothing and improving the smoothness quality. At the same time, they also remove impurities such as lint from the fabric surface to prevent them from affecting the subsequent processing of diapers.

[0019] Preferably, one end of the torsion spring is fixed to the inner sidewall of the mounting frame, and the torsion spring is sleeved on the outer side of the rotating shaft.

[0020] In practical applications, when the shaft deflects, the connecting ring deflects as well. The torsion spring then resets the shaft, causing the scraper to return to its original position. This ensures the scraper is firmly attached to the fabric surface, facilitating smoothing of the fabric.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model, through the setting of a tensioning mechanism, starts a servo motor, drives the turntable to rotate, and causes the vortex groove to rotate, thereby causing the connecting shaft to move inside the vortex groove. This causes the two connecting shafts to drive the second connecting seat to move, causing the second connecting seat to gradually move away from the outside of the slide rod. This causes the connecting rod to deflect in the vertical direction, causing the first connecting seat to drive the mounting plate to rise, and causing the pressure roller to rise, thereby tightening the fabric. At the same time, the pressure roller and the flattening roller clamp the fabric, preventing misalignment of multiple layers of fabric, and can tighten the fabric to prevent it from loosening after flattening, preventing wrinkles from recurring, and avoiding affecting the subsequent processing of diapers.

[0023] 2. This utility model, through the setting of the flattening mechanism, allows the fabric to pass between two scrapers, causing the scrapers to deflect and drive the rotating shaft to deflect, thereby causing the connecting ring to deflect and the torsion spring to deform. The reaction force of the torsion spring is used to reset the rotating shaft, so that the scraper is in close contact with the surface of the fabric. When the fabric moves, the scraper performs preliminary scraping on the surface of the fabric, thereby performing preliminary flattening and improving the flatness quality. At the same time, it removes impurities such as lint from the surface of the fabric to prevent them from affecting the subsequent processing of diapers. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1: A leveling device for diaper production, see [link to example]. Figures 1 to 4 A diaper flattening device includes a workbench 1, with support columns 2 fixed at the four corners of the bottom of the workbench 1 and fixing plates 3 fixed at the four corners of the top of the workbench 1. Guide rollers 301 are fixed on opposite sides of the two fixing plates 3. A mounting frame 4 is fixed on the top of the workbench 1, and a flattening roller 401 rotates through the top between the two sides inside the mounting frame 4. A tensioning mechanism 5 is connected inside the mounting frame 4. A scraping mechanism 6 is connected to the top edge of the workbench 1. The tensioning mechanism 5 clamps and squeezes the fabric with the pressure rollers 504 and the flattening rollers 401 to prevent misalignment of multiple layers of fabric and to tension the fabric to prevent it from loosening after flattening, thus preventing wrinkles from forming again and affecting subsequent processing. The scraping mechanism 6 can initially scrape the fabric and remove lint from the surface of the fabric to ensure cleanliness.

[0036] For details, see Figure 2 and Figure 3 The tensioning mechanism 5 includes limiting rods 501 that slide through the four corners of the top of the mounting frame 4. A mounting plate 502 is fixed to the bottom of the limiting rods 501. A rotating frame 503 is fixed to the top center of the mounting plate 502. A pressure roller 504 rotates between the two sides inside the rotating frame 503. A first connecting seat 505 is symmetrically fixed to the bottom of the mounting plate 502. A connecting rod 506 rotates inside the first connecting seat 505. A sliding rod 507 is symmetrically fixed to the bottom between the two sides inside the mounting frame 4. A second connecting seat 508 slides symmetrically on the outside of the sliding rod 507. A connecting shaft 509 is fixed to the bottom center of the second connecting seat 508. A servo motor 510 is fixed to the top center of the worktable 1. A turntable 511 is fixed to the end of the output shaft of the servo motor 510. A vortex groove 512 is symmetrically opened at the top center of the turntable 511. A stop is fixed to the top of the limiting rods 501. The plate, flattening roller 401 and pressure roller 504 are opposite each other; the bottom end of connecting rod 506 rotates inside the second connecting seat 508; connecting shaft 509 is connected inside the vortex groove 512. When the servo motor 510 is started, the turntable 511 is driven to rotate, causing the vortex groove 512 to rotate, thereby causing the connecting shaft 509 to move inside the vortex groove 512, thereby causing the two connecting shafts 509 to drive the second connecting seat 508 to move, causing the second connecting seat 508 to gradually move away from the outside of the slide rod 507, thereby causing the connecting rod 506 to deflect in the vertical direction, causing the first connecting seat 505 to drive the mounting plate 502 to rise, causing the pressure roller 504 to rise, thereby tightening the fabric, and at the same time, causing the pressure roller 504 and flattening roller 401 to clamp the fabric, avoiding misalignment of multiple layers of fabric, and can tighten the fabric to prevent the fabric from loosening after flattening, preventing wrinkles from being generated again, and avoiding affecting the subsequent processing of diapers.

[0037] It is worth noting that, see Figure 4 The leveling mechanism 6 includes connecting rods 601 symmetrically fixed to the top edge of the workbench 1. A mounting frame 602 is fixed to the top of each connecting rod 601. Rotating shafts 603 symmetrically rotatably extend through both sides of the mounting frame 602. Scrapers 604 are fixed to the opposite ends of the two rotating shafts 603. A connecting ring 605 is fixed to the outer edge of the rotating shaft 603. A torsion spring 606 is fixed to one side of the connecting ring 605. One end of the torsion spring 606 is fixed to the inner wall of the mounting frame 602, and the torsion spring 606 is sleeved on the rotating shaft 603. On the outside, the fabric is passed between the two scrapers 604, causing the scrapers 604 to deflect, which in turn causes the rotating shaft 603 to deflect, thereby causing the connecting ring 605 to deflect and the torsion spring 606 to deform. The reaction force of the torsion spring 606 is used to reset the rotating shaft 603, so that the scrapers 604 are in close contact with the surface of the fabric. When the fabric moves, the scrapers 604 perform preliminary scraping on the surface of the fabric, thereby performing preliminary flattening and improving the flatness quality. At the same time, it also removes impurities such as lint from the surface of the fabric to prevent them from affecting the subsequent processing of diapers.

[0038] In practical application, the fabric is passed through the guide roller 301 and the pressure roller 504. The tensioning mechanism 5 lifts the pressure roller 504 to tighten the fabric. At the same time, the pressure roller 504 and the flattening roller 401 clamp the fabric. The fabric is then pulled to move it. The flattening mechanism 6 performs preliminary flattening and impurity removal on the fabric. As the fabric moves, the flattening roller 401 and the pressure roller 504 rotate to flatten the fabric, preventing wrinkles from forming again after flattening and thus affecting the processing quality of the diapers.
