Description

Technical Field

[0001] This invention belongs to the field of dressing composite cutting technology, specifically a continuous dressing cutting and composite integrated device. Background Technology

[0002] Medical dressings, as crucial medical supplies in wound care and treatment, are experiencing continuous market demand growth due to rising global healthcare standards and an aging population. Furthermore, increasingly stringent requirements are being placed on product quality, production efficiency, and cleanliness. Medical dressings are typically multi-layered composites, composed of various functional materials such as an outer non-woven fabric / gauze layer, a middle absorbent layer, and a bottom waterproof membrane / release paper. The production process requires two core steps: the lamination of these multi-layered materials and the cutting and shaping process, to ensure the dressing's functional integrity and dimensional standardization.

[0003] Currently, the production of medical dressings mostly adopts a decentralized process layout. This involves first using independent lamination equipment to press or glue multiple layers of material together, then transferring the laminated roll to cutting equipment for slitting and die-cutting. These two processes are independent of each other, requiring manual coordination or additional transfer mechanisms. This production model makes the laminated roll prone to wrinkling and shifting during process coordination, leading to misalignment of multiple layers during subsequent cutting, resulting in quality problems such as uneven cuts, delamination, and rough edges.

[0004] Meanwhile, the existing equipment has poor adaptability, and the die-cutting rollers cannot be changed quickly. When changing product specifications, the machine must be stopped manually to disassemble the die-cutting rollers, which is cumbersome and time-consuming, further reducing production efficiency. The composite dressing lacks an effective flattening and guiding mechanism during the transfer to the cutting station, which easily leads to uneven surface and wrinkles, resulting in a decrease in cutting accuracy. It also cannot adapt to cutting and flattening dressings of different thicknesses, resulting in unstable product quality.

[0005] In conclusion, improvements are therefore necessary. Summary of the Invention

[0006] To address the problems mentioned in the background art, the present invention provides a continuous dressing cutting and composite integrated device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous dressing cutting and composite integrated device, comprising a composite module and a cutting module integratedly connected by a connecting seat, wherein the cutting module includes a cutting frame fixedly connected to the connecting seat and a positioning component and a movable component respectively rotatably connected to the upper and lower sides of the inner cavity of the cutting frame, the positioning component including a bottom roller slidably connected to the cutting frame, and the movable component including a die-cutting roller rotatably connected to the cutting frame; the middle area between the bottom roller and the die-cutting roller forms a die-cutting area; The lower end of the inner cavity of the cutting frame is equipped with a contact component for ejecting the movable component from the inner cavity of the cutting frame for replacement and a snap-fit ​​component for fixing the movable component in the inner cavity of the cutting frame. The abutting component includes a pusher that is slidably connected inside the cutting frame, a rotating component that is rotatably connected to the cutting frame and abuts against the moving component, and a cam belt intermittent component that is meshed with the pusher and used to abut against the upward movement of the rotating component. The rotating component includes a trapezoidal rotating plate slidably connected inside the cutting frame. One end of the trapezoidal rotating plate is elastically connected to the cutting frame via a second spring telescopic cylinder. The actuating component includes a frame body that abuts against one end of the bottom roller. The bottom end of the frame body is elastically connected to the cutting frame via a first spring telescopic cylinder. The lower end of the frame body is provided with a rack that meshes with the intermittent cam belt assembly.

[0008] Preferably, hydraulic telescopic components are installed at both ends of the bottom roller, and the end of the hydraulic telescopic component away from the bottom roller is fixedly connected to the cutting frame.

[0009] Preferably, one end of the die-cutting roller is connected to a servo motor via a cross block, and the servo motor is fixed to the cutting frame; The output end of the servo motor is connected to a smoothing module located above the connector.

[0010] Preferably, the cam belt intermittent assembly includes a cam that abuts against a trapezoidal rotating plate, a spur gear that meshes with a rack at the lower end of the frame, and a belt for driving the cam and the spur gear to rotate.

[0011] Preferably, the snap-fit ​​component includes a first electric telescopic rod fixedly connected inside the cutting frame, the top of the first electric telescopic rod is fixedly connected to a snap ring that fits against one end of the die-cutting roller, and a snap-fit ​​plate is movably snapped onto one side of the cutting frame; The contact wall between the retaining ring and the die-cutting roller is polished.

[0012] Preferably, the smoothing module includes two flattening rollers rotatably connected above the connecting seat and a plurality of belt assemblies for connecting the two flattening rollers; One of the belt assemblies is used to drive the flattening roller and the output end of the servo motor.

[0013] Preferably, the flattening roller includes a roller body rotatably connected to a connecting seat, and a plurality of arc-shaped pads are equidistantly connected to the middle end of the roller body in an annular shape; The contact surface between the arc-shaped pad and the dressing is polished. A first spring is provided on the inner side of the arc-shaped pad, and the arc-shaped pad is elastically connected to the roller body through the first spring.

[0014] Preferably, a second electric telescopic rod is installed at one end of the roller body, and the output end of the second electric telescopic rod extends movably into the interior of the roller body and is located in the middle area of ​​one end of a plurality of arc-shaped pads.

[0015] Preferably, an annular push plate is installed on the middle area of ​​the arc-shaped pad at the output end of the second electric telescopic rod. The end of the annular push plate away from the second electric telescopic rod abuts against the arc-shaped pad, and the side of the arc-shaped pad near the annular push plate has an oblique angle.

[0016] Preferably, when the second electric telescopic rod operates to push multiple arc-shaped pads from the inside of the roller body outward through the annular push plate, the gap between the arc-shaped pads and the top surface of the connecting seat can only be filled with the minimum thickness of the composite material. When the second electric telescopic rod operates and its output end reverses to reset, the push on the multiple arc-shaped pads is released by the annular push plate. The multiple arc-shaped pads will move closer to the outer wall of the roller body through the first spring to achieve reset. At this time, the gap area between the arc-shaped pads and the top surface of the connecting seat can be filled with the composite material of the maximum thickness value.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a hydraulic telescopic component to move the bottom roller upwards, thereby altering the distance between the bottom roller and the die-cutting roller. This adapts to cutting dressings of varying thicknesses. Simultaneously, activating a second electric telescopic rod causes its output end to contact an arc-shaped pad via a ring-shaped push plate, extending multiple arc-shaped pads outwards. This facilitates the flattening of dressings of different thicknesses, effectively overcoming the limitations of existing methods that only allow continuous cutting of dressings of a single thickness, significantly improving overall applicability. Furthermore, the composite module and cutting module operate as a single unit, eliminating the need for manual connection or additional transfer mechanisms. This effectively prevents wrinkling and misalignment of the dressing caused by manual connection, which can lead to uneven cuts, delamination, and rough edges during subsequent cutting.

[0018] By setting up a flattening roller and a belt assembly, the present invention enables the output end of the servo motor to drive the roller located above the connecting seat to rotate through the belt assembly when the servo motor is running. At this time, the roller will synchronously drive the arc-shaped pad to flatten and limit the continuously conveyed dressing.

[0019] This invention utilizes a combination of rotating components, a cam belt intermittent assembly, and a snap-fit ​​mechanism. The bottom roller presses down on the frame, causing the frame to mesh with the cam belt intermittent assembly via its own rack. This, in turn, drives the trapezoidal rotating plate upwards in the presence of a second spring telescopic cylinder. This causes the die-cutting roller to gradually move towards the other end of the cutting frame. Prior to this, a spring-reset type pressing signal sensor causes the first electric telescopic rod to release its restriction on one end of the die-cutting roller via a retaining ring. This allows the die-cutting roller to be quickly moved out of the cutting frame for rapid replacement. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 9 As shown, the present invention provides a continuous dressing cutting and composite integrated device, including a composite module 200 and a cutting module 300 integratedly connected by a connecting seat 100. The cutting module 300 includes a cutting frame 310 fixedly connected to the connecting seat 100, and a positioning component 320 and a movable component 330 respectively rotatably connected to the upper and lower sides of the inner cavity of the cutting frame 310. The positioning component 320 includes a bottom roller 322 slidably connected to the cutting frame 310, and the movable component 330 includes a die-cutting roller 332 rotatably connected to the cutting frame 310. The middle area of ​​the bottom roller 322 and the die-cutting roller 332 forms a die-cutting area. The lower end of the inner cavity of the cutting frame 310 is provided with abutment component 340 for ejecting the movable component 330 from the inner cavity of the cutting frame 310 for replacement and snap-fit ​​component 350 for fixing the movable component 330 in the inner cavity of the cutting frame 310. The abutting component 340 includes a pusher 341 slidably connected inside the cutting frame 310, a rotating component 342 rotatably connected to the cutting frame 310 and abutting against the movable component 330, and a cam belt intermittent component 343 meshing with the pusher 341 and used to abut against the upward movement of the rotating component 342. The rotating component 342 includes a trapezoidal rotating plate 3421 slidably connected inside the cutting frame 310. One end of the trapezoidal rotating plate 3421 is elastically connected to the cutting frame 310 through a second spring telescopic cylinder 3422. The actuating component 341 includes a frame 3411 that abuts against one end of the bottom roller 322. The bottom end of the frame 3411 is elastically connected to the cutting frame 310 through a first spring telescopic cylinder 3412. The lower end of the frame 3411 is provided with a rack that meshes with the cam belt intermittent assembly 343.

[0024] The above solution enables rapid replacement of the die-cutting roller 332, solving the problems of slow replacement and cumbersome, time-consuming operation in existing technologies. Specifically, through the cooperation of the abutment component 340 and the snap-fit ​​component 350, the snap-fit ​​component 350 can stably fix the die-cutting roller 332, ensuring its stability during the cutting process. When the die-cutting roller 332 needs to be replaced, the pusher component 341 drives the cam to abut against the trapezoidal rotating plate 3421 upward through the meshing of the rack and pinion and the intermittent cam belt component 343. The trapezoidal rotating plate 3421 pushes the movable component 330 out of the inner cavity of the cutting frame 310. At the same time, the second spring telescopic cylinder 3422 and the first spring telescopic cylinder 3412 can realize the reset of the pushing component 341 and the trapezoidal rotating plate 3421. No manual disassembly is required, which greatly shortens the replacement time of the die-cutting roller 332 and improves the continuity of production. At the same time, the frame 3411 abuts against the bottom roller 322, which can simultaneously assist in positioning the bottom roller 322, ensuring the coaxiality of the bottom roller 322 and the die-cutting roller 332 and improving the cutting accuracy.

[0025] Hydraulic telescopic components 321 are installed at both ends of the bottom roller 322, and the end of the hydraulic telescopic component 321 away from the bottom roller 322 is fixedly connected to the cutting frame 310.

[0026] The above solution allows for flexible adjustment of the height of the bottom roller 322 via the hydraulic telescopic component 321, thereby adjusting the die-cutting gap between the bottom roller 322 and the die-cutting roller 332. This adapts to different thicknesses of dressings for cutting, solving the problem of existing technologies being unable to adapt to different thicknesses of dressings for cutting. The hydraulic telescopic component 321 offers high adjustment precision and strong stability, accurately controlling the die-cutting gap according to the dressing thickness. This avoids issues such as incomplete cutting or material bridging due to excessive gap, or excessive gap causing dressing stretching and deformation or blade wear due to insufficient gap. Additionally, it can be used in conjunction with the contact component 340 to adjust the position of the bottom roller 322 when replacing the die-cutting roller 332, facilitating the placement and removal of the die-cutting roller 332 and further improving operational convenience.

[0027] One end of the die-cutting roller 332 is connected to a servo motor 331 via a cross block 333, and the servo motor 331 is fixedly connected to the cutting frame 310. A smoothing module 400 located above the connector 100 is connected to the output end of the servo motor 331.

[0028] The above solution involves connecting the servo motor 331 to the die-cutting roller 332 via the cross block 333, enabling precise speed control of the die-cutting roller 332. This ensures that the die-cutting roller 332 and the dressing conveyor speed are synchronized, preventing dressing stretching and cutting size deviations due to speed mismatch. The cross block 333 connection facilitates the disassembly and installation of the die-cutting roller 332, and, in conjunction with the contact component 340, further improves the replacement efficiency of the die-cutting roller 332. Simultaneously, the servo motor 331 synchronously drives the smoothing module 400, eliminating the need for an additional drive mechanism, reducing equipment costs, and ensuring that the smoothing module 400 and the die-cutting roller 332 rotate at the same speed. This allows the dressing to immediately enter the die-cutting area after smoothing, preventing wrinkling after smoothing and effectively solving the problem of uneven dressing after lamination.

[0029] The cam belt intermittent assembly 343 includes a cam that abuts against a trapezoidal rotating plate 3421, a spur gear that meshes with a rack at the lower end of a frame 3411, and a belt for driving the cam and the spur gear to rotate.

[0030] The above solution employs a cam belt intermittent assembly 343, which meshes with the rack at the lower end of the frame 3411 via a spur gear to achieve stable power transmission. The belt ensures synchronous rotation of the cam and the spur gear, guaranteeing precise coordination between the movement of the pusher 341 and the upward movement of the trapezoidal rotating plate 3421, preventing jamming or incomplete pushing. The cam's contact with the trapezoidal rotating plate 3421 converts rotational motion into linear motion, enabling the trapezoidal rotating plate 3421 to move smoothly upward, thereby smoothly pushing the die-cutting roller 332. This prevents damage to the die-cutting roller 332 due to uneven pushing force. Simultaneously, the intermittent transmission characteristic allows the die-cutting roller 332 to maintain a stable position after being pushed out, facilitating quick replacement by operators and further improving the replacement efficiency and ease of operation of the die-cutting roller 332.

[0031] The snap-fit ​​component 350 includes a first electric telescopic rod 351 fixedly connected inside the cutting frame 310. The top of the first electric telescopic rod 351 is fixedly connected to a snap ring 352 that fits against one end of the die-cutting roller 332. A snap plate 353 is movably snapped onto one side of the cutting frame 310. The contact wall between the retaining ring 352 and the die-cutting roller 332 is polished.

[0032] The above solution is adopted as follows: the first electric telescopic rod 351 can drive the retaining ring 352 to move up and down, realizing the quick fixing and loosening of the die-cutting roller 332. With the cooperation of the retaining plate 353, the die-cutting roller 332 can be limited from both sides, further improving the stability of the die-cutting roller 332 after fixing, avoiding the die-cutting roller 332 from shifting or shaking during the cutting process, and ensuring cutting accuracy. The polishing treatment of the contact wall of the retaining ring 352 can reduce the friction between it and the die-cutting roller 332, avoid scratches and wear on the surface of the die-cutting roller 332, extend the service life of the die-cutting roller 332, and at the same time reduce the frictional resistance when replacing the die-cutting roller 332, making it easier to pick up and put down the die-cutting roller 332. With the cooperation of the abutment component 340, the die-cutting roller 332 can be quickly replaced, improving production efficiency.

[0033] The smoothing module 400 includes two flattening rollers 410 rotatably connected above the connecting seat 100 and a plurality of belt assemblies 420 for connecting the two flattening rollers 410; One of the belt assemblies 420 is used to drive the flattening roller 410 and the output end of the servo motor 331.

[0034] The above solution involves two flattening rollers 410 connected by multiple belt assemblies 420, which can rotate synchronously to smooth the composite dressing in both directions, effectively eliminating wrinkles and looseness on the surface of the dressing, solving the problem of unevenness of the composite dressing, ensuring the flatness of the dressing when it enters the die-cutting area, and improving the cutting accuracy. The belt assembly 420 realizes the power transmission between the servo motor 331 and the flattening roller 410, eliminating the need for an additional drive mechanism, simplifying the equipment structure, reducing equipment costs, and ensuring that the speed of the flattening roller 410 and the die-cutting roller 332 is synchronized, avoiding stretching and displacement of the dressing during the smoothing and cutting process, and further improving the cutting quality of the dressing.

[0035] The flattening roller 410 includes a roller body 412 rotatably connected to the connecting seat 100, and a plurality of arc-shaped pads 411 are equidistantly connected to the middle end of the roller body 412. The contact surface between the curved gasket 411 and the dressing is polished. A first spring 413 is provided on the inner side of the arc-shaped pad 411, and the arc-shaped pad 411 is elastically connected to the roller body 412 through the first spring 413.

[0036] The above solution involves: the arc-shaped pad 411 being elastically connected to the roller 412 via the first spring 413, enabling the arc-shaped pad 411 to elastically expand and contract, adapting to dressings of different thicknesses for flattening, thus solving the problem in the prior art of not being able to adapt to dressings of different thicknesses for flattening; multiple annularly distributed arc-shaped pads 411 can evenly smooth the surface of the dressing, avoiding wrinkles caused by inadequate local smoothing; the polishing treatment of the bonding surface of the arc-shaped pad 411 can reduce friction with the dressing, avoid scratching the dressing surface and causing fiber shedding, ensuring the cleanliness and integrity of the dressing, while the elastic bonding can adapt to slight unevenness on the dressing surface, further improving the smoothing effect.

[0037] A second electric telescopic rod 414 is installed at one end of the roller body 412. The output end of the second electric telescopic rod 414 extends into the interior of the roller body 412 and is located in the middle area of ​​one end of a plurality of arc-shaped pads 411.

[0038] The output end of the second electric telescopic rod 414 is equipped with an annular push plate in the middle area of ​​the arc-shaped pad 411. The end of the annular push plate away from the second electric telescopic rod 414 abuts against the arc-shaped pad 411. The side of the arc-shaped pad 411 closest to the annular push plate has an angled opening.

[0039] The above solution allows the annular pusher plate to evenly transmit the thrust of the second electric telescopic rod 414 to multiple arc-shaped pads 411, ensuring that the multiple arc-shaped pads 411 move radially synchronously and avoiding uneven flattening caused by the movement deviation of a single arc-shaped pad 411. The bevel on one side of the arc-shaped pad 411 can convert the axial thrust of the annular pusher plate into the radial thrust of the arc-shaped pad 411, reducing thrust loss and making the extension and retraction of the arc-shaped pad 411 smoother, avoiding jamming. At the same time, the cooperation between the annular pusher plate and the bevel can precisely control the extension range of the arc-shaped pad 411, further improving the adaptation accuracy to dressings of different thicknesses, ensuring the consistency of the flattening effect, and thus improving the cutting quality of subsequent dressings.

[0040] When the second electric telescopic rod 414 operates, its output end pushes multiple arc-shaped pads 411 from the inside of the roller body 412 outward through the annular push plate. At this time, the gap between the arc-shaped pads 411 and the top surface of the connecting seat 100 can only be filled with the minimum thickness of the composite material. When the second electric telescopic rod 414 operates and its output end is reversed and reset, the push on the multiple arc-shaped pads 411 is released by the annular push plate. The multiple arc-shaped pads 411 will move closer to the outer wall of the roller body 412 through the first spring 413 to achieve reset. At this time, the gap area between the arc-shaped pads 411 and the top surface of the connecting seat 100 can be filled with the composite material of the maximum thickness value.

[0041] Working principle and usage process of this invention: First, after the dressing is compounded by the compounding module 200, the compounded dressing is transported to the area below the smoothing module 400 by the conveyor belt. The servo motor 331 drives the output end to drive two rollers 412 to rotate through the belt assembly 420. When the rollers 412 rotate, the arc-shaped pads 411 on their outer walls flatten the top surface of multiple dressings. When the second electric telescopic rod 414 is activated, its output end pushes the angled end of the arc-shaped pad 411 through the annular push plate, causing multiple arc-shaped pads 411 to unfold outwards synchronously. Conversely, when the second electric telescopic rod 414 is activated, its output end is reset in the opposite direction to release the push on the arc-shaped pad 411. The arc-shaped pad 411 is elastically pulled by the first spring 413, causing the arc-shaped pad 411 to reset. Through the unfolding and resetting characteristics of the arc-shaped pad 411, the smoothing module 400 can flatten dressings of different thicknesses. Secondly, the dressing from the smoothing module 400 is cut by the bottom roller 322 and the die-cutting roller 332, and the cut dressing is collected by the existing collection equipment. By activating the hydraulic telescopic component 321, its output end drives the bottom roller 322 to move up and down in the inner cavity of the cutting frame 310, thereby changing the interval between the bottom roller 322 and the die-cutting roller 332 to adapt to cutting fabrics of different thicknesses.

[0042] When disassembling the die-cutting roller 332: Activating the hydraulic telescopic component 321 causes its output end to drive the bottom roller 322 to move continuously downward, so that the end of the bottom roller 322 located in the inner cavity of the cutting frame 310 pushes the frame 3411 downward. When the frame 3411 moves downward, the rack at its lower end meshes with the spur gear on the cam belt intermittent assembly 343, thereby causing the cam on the cam belt intermittent assembly 343 to intermittently abut against the trapezoidal rotating plate 3421 and move upward. With the cooperation of the second spring telescopic cylinder 3422, the angled end of the trapezoidal rotating plate 3421 intermittently abuts against the die-cutting roller 332. At this time, the die-cutting roller 332 will gradually disengage from the inside of the cross block 333 outward. Prior to this, when the card plate 353 is pulled outward and the bottom roller 322 moves downward, the end away from the rotating part 342 will first contact the spring-reset type pressing signal sensor. Figure 6 This causes the signal to be transmitted to the terminal control center, which then controls the first electric telescopic rod 351 to move so that its output end drives the retaining ring 352 downward, releasing the upward pressure on one end of the die-cutting roller 332; subsequently, as the trapezoidal rotating plate 3421 continuously touches the die-cutting roller 332, the operator can quickly remove the die-cutting roller 332.

[0043] When installing the die-cutting roller 332: The die-cutting roller 332 is inserted into the interior of the cutting frame 310 from one end, and aligned with the cross block 333 through the cross groove on the side wall of the die-cutting roller 332 and locked in place. At this time, the trapezoidal rotating plate 3421 does not contact the die-cutting roller 332. The first electric telescopic rod 351 causes it to abut and limit the side end of the die-cutting roller 332 again through the retaining ring 352. Then the retaining plate 353 is locked onto the cutting frame 310 again to limit the die-cutting roller 332 again.
