Description

Technical Field

[0001] This invention relates to the field of medical device packaging and processing equipment technology, and in particular to a dust-free cutting and sealing synchronous mechanism for sterilized bags and its cutting and sealing method. Background Technology

[0002] Sterilization bags are the core consumables for sterile packaging of medical devices. Their cleanliness and sealing directly determine the sterilization effect and shelf life of medical devices. The production process has extremely high mandatory standards for dust-free, burr-free, and fiber-free cutting and sealing processes. Existing technologies have many inherent defects and are difficult to meet the ISO 8 level dynamic clean production requirements for high-end medical devices: First, traditional cold-blade mechanical cutting relies on physical friction to cut materials. The cutting process is highly frictional, which easily generates a large amount of fiber debris and dust. Moreover, the edges of the bag after cutting have obvious burrs and loose fibers, which are easy to fall off and contaminate the instruments during subsequent use. At the same time, the step-by-step cutting and sealing operations are cumbersome, with low processing efficiency and a high risk of secondary pollution. Second, most existing dust removal equipment is an independent external structure that can only achieve simple dust adsorption. It lacks an integrated dust removal system that includes source electrostatic control, real-time negative pressure capture, and precise multi-stage filtration. It cannot eliminate problems such as material electrostatic adsorption of dust, dust accumulation on waste edges, and fine particle residue. Therefore, this invention proposes a dust-free cutting and sealing synchronous mechanism for sterilization bags to solve the above problems. Summary of the Invention

[0017] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention. Example 1

[0018] according to Figure 1-7 As shown, this embodiment proposes a dust-free cutting and sealing synchronous mechanism for sterilization bags, including a box 1, a feeding rack 2, a limiting roller 3, and a moving frame 4. The box 1 is equipped with an integrated dust removal, dust collection, and ultrasonic cutting and sealing structure. The feeding rack 2 with a feeding mechanism is located on the top left side of the box 1, and the moving frame 4 with a cutting mechanism and the hinged limiting roller 3 are located on the left side. The box 1 is equipped with a dust removal mechanism with a brush roller 6, an ion bar 7, an ion generator 8, and an electrostatic eliminator 9, which, together with a dust collection mechanism with a fan 12 and a filter element 36, achieves dust-free control. The box 1 is equipped with a cutting mechanism with an ultrasonic knife 21 and a limiting mechanism, which can effectively eliminate cutting debris and burrs, simplify processing procedures, improve production efficiency, and build an integrated dust-free clean control system to meet the ISO 8 level dynamic clean production requirements for high-end medical devices.

[0019] The entire system uses the housing 1 as the supporting base. The feeding rack 2 continuously supplies raw materials for sterilization bags, and the limiting roller 3 limits and corrects the material conveying trajectory to ensure stable feeding. Relying on the dust removal and dust collection mechanisms integrated inside the housing 1, the system uses a brush roller 6 for physical dust removal, an electrostatic eliminator 9 to eliminate static electricity in the materials, and an ion generator 8 in conjunction with an ion bar 7 to neutralize residual static electricity and floating dust. Then, the fan 12 and filter element 36 complete the dust filtration and collection, achieving fully enclosed dust-free control. At the same time, the ultrasonic cutting mechanism mounted on the mobile frame 4 replaces the traditional cold knife cutting, and the limiting mechanism precisely presses and positions the materials to achieve dust-free, burr-free, integrated cutting and sealing operations, which are compatible with ISO 8 clean production standards.

[0020] In this embodiment, the dust removal mechanism also includes a dust collection chamber 5, a brush roller 6 is rotatably connected to the lower part of the box body 1, an electrostatic eliminator 9 is provided on the left side of the brush roller 6, and an ion wind bar 7 and an ion generator 8 are arranged in sequence on the right side. A No. 1 motor 16 is fixed on the outside of the box body 1, and the output end of the No. 1 motor 16 is fixedly connected to the brush roller 6. Multiple conveying rollers 10 are provided at equal intervals at the bottom of the box body 1.

[0021] The material is smoothly conveyed by the conveyor roller 10, and the No. 1 motor 16 provides power to drive the brush roller 6 to rotate continuously, physically brushing away the dust and impurities attached to the surface of the sterilization bag. During the material movement, the static eliminator 9 first eliminates the surface static electricity generated during the production and conveying of the sterilization bag, avoiding the difficulty in cleaning due to static adsorption of dust. Subsequently, the ion generator 8 works to generate an ion airflow, which is blown out by the ion bar 7 to further neutralize the residual static electricity of the material and blow away the fine floating dust. The brushed dust is uniformly collected in the dust collection chamber 5, providing a basis for subsequent dust collection and purification.

[0022] In a preferred embodiment, the speed of the first motor 16 is adjustable from 200 to 600 rpm, and the contact interference between the bristles of the brush roller 6 and the material surface is controlled at 1 to 3 mm, so as to ensure the physical dust removal effect while avoiding scratching the substrate of the sterilization bag.

[0023] In this embodiment, the dust collection mechanism includes a fixed base 11, an air supply pipe 13, an exhaust pipe 14, and a diversion pipe 15. The fixed base 11 with a filter element 36 is connected above the dust collection chamber 5. The top of the filter element 36 is provided with a threaded head 17 for threaded connection. The input end of the fan 12 is detachably connected to the filter element 36 through the air supply pipe 13. The output end of the fan 12 is connected to the exhaust pipe 14. The exhaust pipe 14 is connected to the ion fan bar 7 through the diversion pipe 15.

[0024] When the fan 12 starts, it generates negative pressure suction, which draws the dust-laden airflow from the dust collection chamber 5 through the air supply pipe 13. The airflow is filtered and purified by the filter element 36 inside the fixed base 11, and the dust is trapped and collected. The clean air is discharged sequentially through the fan 12 and the exhaust pipe 14. Part of the clean airflow is introduced into the ion bar 7 through the diversion pipe 15, which provides airflow power for the ion air delivery operation of the ion bar 7, realizing the integrated linkage of dust removal, dust collection and air delivery. The filter element 36 can be detached and installed through the top thread head 17, which is convenient for later disassembly, replacement and cleaning.

[0025] In a preferred embodiment, a flow regulating valve (not shown in the figure) can be installed on the diversion pipe 15 to regulate the airflow rate supplied to the ion fan bar 7, keeping it within a suitable range of 0.3~0.8 m³ / min, ensuring a balance between ion transport efficiency and dust removal effect; at the same time, this closed-loop air path design ensures that the purified gas discharged from the fan 12 will not be directly discharged into the workshop environment to cause secondary turbulence, but will instead circulate and act on the surface of the material, greatly improving the dust particle control capability in the cleanroom.

[0026] In this embodiment, the cutting mechanism includes a guide rod 18, a moving arm 19, a high-frequency transducer 20, and a lead screw 24. The guide rod 18 is fixed inside the moving frame 4 and the moving arm 19 is slidably connected. A second motor 22 is provided at the bottom of the moving arm 19. The output end of the second motor 22 is connected to the high-frequency transducer 20 and the ultrasonic knife 21. The lead screw 24 is provided inside the moving frame 4. A third motor 23 at the top of the moving arm 19 is connected to the lead screw 24 for transmission.

[0027] Motor 23 drives the lead screw 24 to rotate. Utilizing the threaded transmission characteristics of the lead screw 24, it drives the moving arm 19 to slide precisely in a straight line along the guide rod 18, achieving lateral position adjustment of the ultrasonic blade 21 to adapt to different cutting size requirements. Motor 22 drives the high-frequency transducer 20 to work, converting electrical energy into high-frequency mechanical vibration energy, which is transmitted to the ultrasonic blade 21, causing it to generate high-frequency vibration. This high-frequency vibration frictional heat achieves burr-free cutting and simultaneous edge sealing of the sterilization bag, replacing traditional mechanical hard cutting and eliminating debris generation. In this embodiment, the operating frequency of the high-frequency transducer 20 is preferably 20kHz~40kHz, and the amplitude is controlled between 10~50μm. It can automatically match the vibration power according to the material thickness of the sterilization bag (usually a 50~200μm composite film), ensuring smooth fusion of the cut edges and achieving one-time completion of sealing and cutting.

[0028] In this embodiment, a cutting table 25 is fixed inside the housing 1, and a cutting groove 26 matching the ultrasonic knife 21 is opened inside the cutting table 25.

[0029] The cutting table 25 serves as the bearing reference platform for the sterilization bag cutting operation, providing stable support for the material. When the ultrasonic knife 21 moves downward for cutting, the knife groove 26 provides clearance for the knife, avoiding hard collision and wear between the ultrasonic knife 21 and the cutting table 25. At the same time, it ensures that the ultrasonic knife 21 completely penetrates the sterilization bag material, ensuring thorough cutting and tight sealing, improving cutting accuracy and equipment lifespan.

[0030] In this embodiment, the limiting mechanism includes a base plate 27, a movable plate 28, a spring telescopic rod 29, a pressure plate 30, a cylinder 31, and a wedge block 32. The base plate 27 is fixed to the bottom of the box 1. The movable plate 28 is provided on one side of the base plate 27. The movable plate 28 is connected to the pressure plate 30 above the cutting table 25 through the spring telescopic rod 29. The wedge block 32 at the output end of the cylinder 31 is in contact with the movable plate 28 for transmission.

[0031] Before the cutting operation, the cylinder 31 extends and retracts to drive the wedge block 32 to move horizontally. The wedge block 32 presses against the movable plate 28, pushing the movable plate 28 to move. Through the spring telescopic rod 29, the pressure plate 30 moves downward to press the sterilization bag material on the cutting table 25. The pressing and limiting effect of the pressure plate 30 is used to prevent material deviation and wrinkles during the cutting process, ensuring the accuracy of the cutting size. After the operation is completed, the cylinder 31 resets, and the pressure plate 30 is lifted by the elastic force generated by the spring telescopic rod 29, so that the material can continue to be conveyed.

[0032] In a preferred embodiment, the timing of the cylinder 31's operation is interlocked with the downward cutting action of the ultrasonic cutter 21: the cylinder 31 starts 0.3 to 0.6 seconds before the ultrasonic cutter 21 descends; after the pressure plate 30 fully clamps the material, the ultrasonic cutter 21 then performs the downward cutting action; after cutting is completed, the ultrasonic cutter 21 first rises and resets, and the cylinder 31 then resets and releases the pressure plate 30 after a delay of 0.2 to 0.4 seconds. This timing control effectively prevents the material from shifting or wrinkling due to ultrasonic vibration when it is not clamped, significantly improving cutting accuracy.

[0033] The feeding mechanism includes a No. 4 motor 33, a rotating roller 34, a transmission assembly 35, and an arc-shaped groove plate 37. The arc-shaped groove plate 37 is symmetrically engaged on both sides of the feeding frame 2. Two sets of rotating rollers 34 are rotatably connected inside the feeding frame 2. The two sets of rotating rollers 34 are driven by the transmission assembly 35 composed of sprockets and chains.

[0034] The arc-shaped groove plate 37 limits and supports the raw material roll of the sterilization bag to prevent the raw material roll from shifting and falling off; the two sets of rotating rollers 34 serve as the feeding transmission carrier, and achieve synchronous linkage transmission through the transmission assembly 35 composed of sprockets and chains, ensuring uniform feeding speed and stable tension, providing a stable material supply for the continuous cutting operation of the whole machine, and ensuring production continuity.

[0035] In this embodiment, the fourth motor 33 is fixed to the outside of the feeding frame 2, and the output end of the fourth motor 33 is fixedly connected to any one of the rotating rollers 34 to realize synchronous rotation of the rotating rollers 34 for feeding.

[0036] Motor 33, the fourth motor, serves as the power source for the feeding mechanism. It outputs torque to drive the corresponding rotating roller 34 to rotate. In conjunction with the linkage of the transmission component 35, it drives the two sets of rotating rollers 34 to rotate synchronously and in the same direction, realizing automatic and uniform feeding of the raw materials for sterilization bags. It can match the cutting rhythm of the whole machine, eliminating the need for manual feeding, simplifying the production process, and improving the degree of automation and production efficiency.

[0037] This mechanism uses housing 1 as the overall installation base. During operation, motor 33 drives the rotating roller 34 on the feeding rack 2 to rotate. The transmission assembly 35 enables synchronous feeding of the two rotating rollers 34. The arc-shaped groove plate 37 limits and protects the raw material roll. After the sterilization bag material is corrected by the limiting roller 3, it is uniformly conveyed to the cutting table 25 by the conveying roller 10 at the bottom of housing 1. During the feeding process, motor 16 drives the brush roller 6 to rotate and brush away the dust on the surface of the material. In conjunction with the static eliminator 9, ion generator 8 and ion bar 7, static electricity of the material is eliminated and fine dust is removed. At the same time, the fan 12 draws the dusty airflow from the dust collection chamber 5 through the air supply pipe 13. After being filtered and purified by the filter element 36, the clean airflow is supplied to the ion bar 7 through the diversion pipe 15, forming a... An integrated closed-loop dust-free system is used. After the material arrives, cylinder 31 drives wedge block 32 to move, and through movable plate 28 and spring telescopic rod 29, pressure plate 30 is driven to press the material, achieving precise positioning. Then, motor 23 drives lead screw 24 to rotate, driving moving arm 19 to precisely move along guide rod 18 to adjust the cutting position. Motor 22, in conjunction with high-frequency transducer 20, drives ultrasonic knife 21 to vibrate at high frequency, which, in conjunction with the knife groove 26 of cutting table 25, completes high-precision cutting and synchronous sealing of sterilization bags without debris or burrs. The entire process realizes automated dust-free integrated production, effectively solving the defects of traditional equipment such as cumbersome processes, easy generation of burrs and debris, and insufficient cleanliness, and meeting the ISO8 level dynamic clean production requirements for medical devices.
