Description

Technical Field

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

[0002] Adult diapers are disposable paper-based incontinence products, a type of adult care product primarily intended for use by incontinent adults. The manufacturing process for adult diapers involves cutting fabric into individual diaper sizes.

[0003] Patent application CN221814455U discloses an adult diaper production equipment, relating to the technical field of diaper production equipment. The equipment includes a workbench with multiple support legs installed at its bottom. In use, fabric is placed on a conveyor belt for transport. When cutting is required, an electric telescopic rod is activated, causing a lifting plate to move downwards. When multiple pressing rollers contact the fabric, the pressing rollers roll to both sides under the squeezing action of the lifting plate, straightening and smoothing the fabric. As the pressing rollers move to both sides, four connecting components drive four sliders to slide along rectangular grooves, squeezing four reset components. When the lifting plate descends to a certain position, a cutter, in conjunction with the support components, performs a cutting function. When the lifting plate moves upwards, gravity and the elasticity of the reset components cause the sliders to reset, thus resetting the pressing rollers.

[0004] However, in practical applications, traditional diaper production cutting devices typically have separate drive units for the cutting and conveying structures. The cutting and conveying actions are powered by different drive units. This approach not only requires multiple drive units, increasing equipment costs, space requirements, and overall device complexity, but also necessitates fine-tuning the rotation speeds of multiple drive units during actual production to achieve continuous and precise cutting of diapers. This requires matching the operating rhythms of the cutting and conveying structures and ensuring their coordinated operation. The entire adjustment process is not only cumbersome but also demands a high level of technical skill and experience from the operators. Improper adjustment can lead to discontinuous cutting and unstable diaper quality, severely impacting production efficiency and product quality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a diaper production cutting device. This addresses the current problem in practical applications where traditional diaper production cutting devices typically have separate drive units for the cutting and conveying structures. The cutting and conveying actions are powered by different drive units, which not only requires multiple drive units, increasing equipment cost, space occupation, and overall device complexity, but also necessitates fine-tuning the rotation speeds of multiple drive units during actual production to achieve continuous and precise cutting of diapers. This requires matching the operating rhythms of the cutting and conveying structures, ensuring coordinated operation. The entire adjustment process is not only cumbersome but also demands a high level of technical skill and experience from the operators. Improper adjustment can lead to discontinuous cutting and unstable diaper quality, severely impacting production efficiency and product quality.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a diaper production cutting device is designed, including a first fixed plate and a second fixed plate. A dual-axis motor is installed on the surface of the first fixed plate. The output shaft of one end of the dual-axis motor passes through the first fixed plate and extends between the first fixed plate and the second fixed plate. It is connected to a first rotating roller between the first fixed plate and the second fixed plate through a coupling. A conveyor belt is sleeved on the outside of the first rotating roller for conveying diapers. The output shaft of the other end of the dual-axis motor is connected to a transmission component for cutting the diapers.

[0007] In practical applications, one output shaft of the dual-axis motor drives the first rotating roller to rotate through a coupling, thereby driving the conveyor belt mounted on the first rotating roller to operate continuously and realize the conveying of diaper fabric. The conveying function is realized by a single motor, which reduces the dependence on independent conveying drive devices, simplifies the structure, reduces equipment costs and maintenance difficulty, and improves conveying stability.

[0008] Preferably, the transmission assembly includes a first pulley, a transmission belt externally connected to the first pulley, and a second pulley internally connected to the other end of the transmission belt.

[0009] In practical applications, the output shaft at the other end of the dual-axis motor drives the first pulley to rotate, and the power is transmitted to the second pulley via the transmission belt to achieve secondary power output. The structure of pulleys and transmission belts makes the power transmission smooth and the noise low, and can effectively transmit the driving force of the motor to the subsequent shearing mechanism to ensure synchronous and reliable operation.

[0010] Preferably, one end of the second pulley is connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the inner ring of the first bearing installed on the surface of the first fixed plate. A fixing ring is sleeved on the outside of the connecting rod, and the fixing ring is fixedly connected to the connecting rod.

[0011] In practical applications, the second pulley is connected to the first bearing via a connecting rod. A retaining ring is fitted onto the connecting rod and fixedly connected to it. The bearing enables smooth rotation and provides stable support for the subsequent driving of the elliptical frame plate.

[0012] Preferably, the fixing ring extends into the lower part of the elliptical frame plate and is fixedly connected to the inner wall of the elliptical frame plate by multiple support rods.

[0013] In practical applications, the fixing ring is located in the lower inner part of the elliptical frame plate and is fixedly connected to the inner wall of the elliptical frame plate through the support rod. When the fixing ring rotates with the connecting rod, it will drive the elliptical frame plate to move as a whole, so that the elliptical frame plate can rotate under a fixed trajectory, thereby converting the rotational motion of the motor into the up-and-down reciprocating motion of the limiting rod, driving the shearing action.

[0014] Preferably, the top of the elliptical frame plate is inserted between two drive rods, one end of the drive rod is fixed with a shearing housing, the bottom of the shearing housing is provided with an installation groove, an installation plate is inserted into the installation groove, and a shearing blade is fixed at the bottom of the installation plate.

[0015] In practical applications, the top of the elliptical frame plate is inserted between two drive rods. When the elliptical frame plate rotates, the drive rods move up and down, thereby driving the shearing housing fixed on it to reciprocate. The shearing blade then completes the shearing, realizing mechanical synchronization between conveying and shearing. This avoids the speed adjustment problem under multiple motor independent drives, ensures that the shearing rhythm matches the conveying rhythm, and results in higher shearing accuracy and more stable product quality.

[0016] Preferably, the shear housing has multiple round holes on its side, and fixing bolts pass through each of the multiple round holes. The fixing bolts extend into the mounting groove of the shear housing and connect with the threaded groove on the surface of the mounting plate inserted into the mounting groove to limit and fix the shear blade.

[0017] In practical applications, the bottom of the shear housing is provided with a mounting groove, into which the mounting plate is embedded and fixed to the shear blade. The round hole on the side of the housing is used to install fixing bolts. The bolts are locked with the threaded groove of the mounting plate to fix the blade. This structure facilitates the quick replacement and fixing of the shear blade, improves maintenance efficiency, and ensures the stability of the blade during the shearing process, avoiding poor shearing caused by loosening.

[0018] Preferably, one end of an L-shaped plate is installed on both sides of the shearing shell, and a hot press shell is fixed to the other end of the L-shaped plate. Multiple electric heating tubes are installed inside the hot press shell, and an opening is provided at its bottom, with a cover plate installed inside the opening.

[0019] In practical applications, the L-shaped plates on both sides of the shear shell drive the hot-press shell to move up and down. The electric heating tube inside the hot-press shell continuously generates heat, so that the hot-press shell heat-presses the diaper before and after shearing. The integrated shearing and hot-pressing functions not only effectively shape the product before and after shearing and improve the fit, but also reduce the use of independent hot-pressing equipment, reducing the number of devices and the floor space required.

[0020] Preferably, both ends of the shear shell are penetrated by limiting rods, the top of the limiting rods is fixed with a device top plate, and the bottom is connected to the first fixing plate and the second fixing plate respectively. The four corners of the bottom of the device top plate are connected to the first fixing plate and the second fixing plate through support columns.

[0021] Preferably, a plurality of second rotating rollers are sleeved at the end of the conveyor belt away from the first rotating roller, and each end of the plurality of second rotating rollers is rotatably connected to a second bearing, which is installed on the inner wall of the first fixed plate and the second fixed plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model combines a dual-axis motor, a conveyor belt, and a transmission assembly. Driven by the dual-axis motor, the conveyor belt between the first and second fixed plates rotates, thus conveying the diapers to be cut. Simultaneously, the dual-axis motor also drives the first pulley to rotate, which in turn drives the second pulley via the transmission belt, causing the elliptical frame plate to rotate. Since the top of the elliptical frame plate extends between the two drive rods, and its lower inner part is connected to a fixed ring via a support rod, the rotation of the elliptical frame plate drives the drive rods to move up and down, thereby driving the cutting structure to complete the up-and-down reciprocating motion and continuously cut the diapers on the conveyor belt. By using this method of synchronously driving the conveyor belt and the elliptical frame plate with a dual-axis motor, the rhythm of conveying and cutting is kept consistent. Workers only need to adjust the placement spacing of the diapers to achieve continuous and efficient cutting without the need for additional drive devices.

[0024] 2. This utility model combines a shearing shell, an L-shaped plate, and a hot-pressing shell. While the shearing shell moves up and down, the L-shaped plate and the hot-pressing shell also move up and down synchronously. Because the hot-pressing shell is equipped with an electric heating element, it continuously generates heat during operation, heating the shell and allowing it to undergo multiple hot-pressing processes before and after the diaper is sheared. By integrating the hot-pressing structure with the shearing structure, not only is the coordinated operation of shearing and hot-pressing achieved, but the need for an additional drive device is also eliminated, simplifying the structure and improving work efficiency.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: A cutting device for diaper production, see [link / reference] Figures 1 to 4The device includes a first fixed plate 1 and a second fixed plate 101. A dual-axis motor 2 is mounted on the surface of the first fixed plate 1. The output shaft of one end of the dual-axis motor 2 passes through the first fixed plate 1 and extends between the first fixed plate 1 and the second fixed plate 101. It is connected to a first rotating roller 216 between the first fixed plate 1 and the second fixed plate 101 via a coupling. A conveyor belt 217 is sleeved on the outside of the first rotating roller 216. A plurality of second rotating rollers 218 are sleeved on the inside of the conveyor belt 217 at the end away from the first rotating roller 216. Both ends of the plurality of second rotating rollers 218 are rotatably connected to second bearings 219. The second bearings 219 are installed on the inner walls of the first fixed plate 1 and the second fixed plate 101 for conveying diapers. The output shaft of the other end of the dual-axis motor 2 is connected to a transmission assembly for cutting diapers.

[0032] When this device is working, the dual-axis motor 2 outputs power simultaneously. One end drives the first rotating roller 216 to rotate through the coupling, thereby driving the conveyor belt 217 sleeved on the outside to run continuously and realize the conveying of diapers. The other end transmits power to the second pulley 203 through the pulley and the transmission belt 202.

[0033] For details, see Figure 1 The transmission assembly includes a first pulley 201, a transmission belt 202 externally connected to the first pulley 201, a second pulley 203 internally connected to the other end of the transmission belt 202, a connecting rod 207 connected to one end of the second pulley 203, and a rotatable connection between the other end of the connecting rod 207 and the inner ring of the first bearing 204 mounted on the surface of the first fixed plate 1. A fixing ring 205 is sleeved on the outside of the connecting rod 207 and is fixedly connected to the connecting rod 207. The fixing ring 205 extends into the lower part of the elliptical frame plate 220 and is fixedly connected to the inner wall of the elliptical frame plate 220 through multiple support rods 206. The top of the elliptical frame plate 220 is inserted between two drive rods 210. A shearing housing 209 is fixed to one end of the drive rod 210. The bottom of the shearing housing 209 is provided with an installation groove. An installation plate 213 is inserted into the installation groove. A shearing blade 215 is fixed to the bottom of the installation plate 213.

[0034] When the second pulley 203 rotates, it drives the connecting rod 207 at its end to move. The connecting rod 207 is supported by the first bearing 204 and fitted with a fixing ring 205. The fixing ring 205 is connected to the lower part of the elliptical frame plate 220. As the second pulley 203 continues to rotate, the fixing ring 205 drives the elliptical frame plate 220 to rotate eccentrically. The top of the elliptical frame plate 220 is engaged between the two drive rods 210, causing the drive rods 210 to move up and down reciprocally. A shearing housing 209 is fixed to one end of the drive rod 210. Therefore, the shearing housing 209 moves up and down reciprocally under the drive of the drive rod 210, thereby driving the shearing blade 215 installed at the bottom of the housing to continuously shear the diapers conveyed on the conveyor belt 217.

[0035] Further, see Figure 2 The shear housing 209 has multiple round holes 211 on its side, and fixing bolts 212 pass through each of the multiple round holes 211. The fixing bolts 212 extend into the mounting groove of the shear housing 209 and connect with the threaded groove 214 on the surface of the mounting plate 213 inserted into the mounting groove, thereby limiting and fixing the shear blade 215.

[0036] Multiple circular holes 211 are provided on the side wall of the shear housing 209. The fixing bolts 212 in the circular holes 211 are connected to the threaded grooves 214 on the mounting plate 213 to fix the shearing blade 215, ensuring that the blade is stable and does not shift during the shearing process. At the same time, the shearing blade 215 can be replaced and maintained by removing and installing the fixing bolts 212.

[0037] It is worth noting that, see Figure 3 Both sides of the shear shell 209 are equipped with one end of an L-shaped plate 3, and the other end of the L-shaped plate 3 is fixed with a hot press shell 301. Multiple electric heating tubes 302 are installed inside the hot press shell 301, and an opening is provided at its bottom, with a cover plate 303 installed inside the opening.

[0038] The shearing shell 209 has L-shaped plates 3 on both sides, and a heat-pressing shell 301 is fixed to the other end of the L-shaped plates 3. When the shearing shell 209 moves up and down with the limiting rod 208, the L-shaped plates 3 and the heat-pressing shell 301 also move up and down synchronously. The heat-pressing shell 301 is equipped with an electric heating tube, which can continuously heat during operation, so that the heat-pressing shell 301 heat-presses and shapes the diaper before and after shearing. This not only improves the fit and aesthetics of the diaper edge, but also avoids rough edges caused by shearing, thus improving product quality.

[0039] It is worth noting that, see Figure 1Both ends of the shear shell 209 are penetrated by limiting rods 208. The top of the limiting rod 208 is fixed with a device top plate 103, and the bottom is connected to the first fixing plate 1 and the second fixing plate 101 respectively. The four corners of the bottom of the device top plate 103 are connected to the first fixing plate 1 and the second fixing plate 101 through support columns 102.

[0040] To ensure the stability of the shear shell 209 during reciprocating motion, limiting rods 208 are inserted through both ends of the shear shell 209. The upper end of the limiting rods 208 is fixedly connected to the top plate 103 of the device. The top plate forms a stable support with the two side fixing plates through the support column 102, thereby ensuring that the shear shell 209 does not shift or shake when moving up and down.

[0041] It should be noted that the electric heating tube 302 inside the heat-pressing shell 301 of this utility model is electrically connected to an external temperature controller. The temperature controller can monitor and adjust the working temperature of the electric heating tube in real time, thereby ensuring that the heat-pressing shell 301 is always within a suitable temperature range during operation, avoiding damage to the diaper due to excessive temperature, and also improving the safety and stability of the heat-pressing process.

[0042] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0043] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
