Description

Technical Field

[0001] This invention relates to the field of blister packaging technology, specifically to a semi-automatic blister cutting and filling equipment. Background Technology

[0002] Blister packaging is a mainstream packaging form in the pharmaceutical, food, and daily chemical industries. Made of aluminum-plastic, aluminum-aluminum, or paper-plastic materials, it offers high barrier properties and portability, and must comply with industry standards such as GMP. Semi-automatic blister packaging cutting and filling equipment integrates blister film unwinding, forming, filling, heat sealing, and cutting. A centralized control system manages multiple modules working collaboratively, enabling precise packaging from film material to finished blister packs. Existing blister packaging equipment suffers from multiple technical limitations, failing to meet the demands for high-precision, high-efficiency, and flexible production, and is also ill-suited to the compliance requirements of high-end industries such as pharmaceuticals. Therefore, semi-automatic blister packaging cutting and filling equipment is needed.

[0003] In existing technologies, the cutting blades in blister cutting and filling equipment are mostly connected by bolts. When the cutting blades need to be disassembled and adjusted, special tools are required for disassembly and assembly, which takes a long time and affects the efficiency of equipment maintenance and production continuity. This results in insufficient equipment production efficiency, long equipment downtime, difficulty in adapting to the rapid switching production needs of multi-specification blister packs, and also restricts the overall capacity improvement.

[0013] Preferably, a servo motor is fixedly connected to the outer wall of the support plate, and an unwinding roller is fixedly installed at the output end of the servo motor. The outer wall of the unwinding roller is rotatably connected to the inside of the support plate.

[0014] A method for using a semi-automatic blister pack cutting and filling equipment includes the following steps:

[0015] S1. By issuing control commands through the control panel of the operating equipment, the servo motor three is started, and the servo synchronous transmission system is used to smoothly transport the film material that has completed the forming process to the filling component at the filling station, so as to prepare for the subsequent filling process.

[0016] S2. After the film material arrives, start the second servo motor to complete the precise feeding operation of the material according to the preset filling dosage. At the same time, the anti-dust component and the filling component operate synchronously.

[0017] S3. After the film material is filled, it is transported to the heat sealing machine for heat sealing. After sealing, hydraulic cylinder one is started, and the cutting mechanism is driven by hydraulic cylinder one to cut the sealed film material to a fixed length to form an independent finished product.

[0018] S4. After the qualified finished film material is cut, it is collected in a unified and orderly manner by the material receiving component; at the same time, hydraulic cylinder two and servo motor one are started to stably transport the waste material generated during the cutting process to the outside and discharge it, so as to realize the separation of finished product and waste material.

[0019] Working principle: When the equipment is needed, first start the servo motor three through the control panel. The servo motor three drives the unwinding roller to rotate, and conveys the pre-formed blister film material to the filling station along the guide wheel. When the film material reaches the bottom of the filling component, the servo motor two drives the rotating shaft and auger to rotate, and pushes the material in the storage box to the filling head with a preset metering to complete the quantitative filling. During the filling process, the anti-dust component is activated simultaneously. It suppresses the spread of dust through negative pressure adsorption or airflow shielding mechanism, ensuring the cleanliness of the working environment and the utilization rate of materials. After the filling is completed, the film material continues to be conveyed forward and the heat sealer heat-presses the top of the blister to form a sealed packaging unit.

[0020] After sealing, the membrane material enters the cutting station. During this process, the limiting roller and the conveying roller work together to ensure constant membrane tension and avoid deviation or wrinkles. Then, the hydraulic cylinder drives the slide plate to descend vertically along the limiting frame. The lower pressure plate contacts the membrane surface first, and pre-pressing and fixing are achieved through the flexible contact of the rubber pad. As the slide plate continues to move down, the buffer assembly composed of the telescopic rod and the spring undergoes elastic deformation, absorbing impact energy and maintaining constant clamping force. At the same time, the cutting blade penetrates the reserved slot of the lower pressure plate to punch the membrane material. The buffer assembly effectively suppresses vibration transmission and ensures that the cut is flat and burr-free. After cutting, the hydraulic cylinder resets, and the finished blister slides down the guide plate to the receiving box. The waste material is pressed by the roller under the drive of the hydraulic cylinder and output in a direction with the conveying roller driven by the servo motor.

[0021] The cutting blade can be quickly unlocked via a cam handle. Moving the cam handle rotates it around the connecting shaft, releasing the cam profile from the pressure on the insert. The elastic potential energy of spring one pushes the limiting ring, causing the insert to disengage from the slot and slide into the cylinder. At this point, the cutting blade is unconstrained and can be pulled out along the inner cavity of the connecting block. After a new cutting blade is inserted, when the slot aligns with the insert, moving the cam handle in the opposite direction pushes the insert back into the slot, locking the blade. During this process, the insert causes the limiting ring to slide along the inner wall of the cylinder, compressing spring one and generating elastic potential energy. This allows for quick blade removal and installation, shortening replacement time and improving efficiency.

[0022] This invention provides a semi-automatic blister pack cutting and filling device. It has the following beneficial effects:

[0023] 1. This invention allows the cutting blade to be quickly removed and installed by rotating the cam handle around the connecting shaft. The cam releases the pressure on the insert post, and the spring, through the limiting ring, drives the insert post to retract into the cylinder and disengage from the slot. After a new blade is installed, the handle is rotated in the opposite direction, and the cam pushes the insert post into the slot to lock it in place. The insert post slides with the limiting ring and compresses the spring to store energy, which shortens the blade replacement time and improves the blade replacement efficiency.

[0024] 2. This invention uses the telescopic rod and spring 2 in combination to buffer and reduce shock and maintain constant pressure. When the hydraulic cylinder presses down to cut, it can smoothly release the impact force. Together with the pressure plate, it applies continuous and uniform pressure to the film material, which effectively suppresses equipment vibration, avoids film material displacement and damage, makes the cut surface flat and burr-free, and improves cutting accuracy and finished product quality.

[0025] 3. This invention uses a servo synchronous transmission system composed of a servo motor and a high-precision encoder to achieve multi-station linkage control, ensuring precise matching of the cycle times of each process, including film material conveying, filling, heat sealing, and cutting, eliminating cumulative errors, and achieving the effects of improving the stability of the entire line operation, reducing material waste, and ensuring dosage consistency.

[0026] 4. Through the modular layout of the material receiving component and the waste output mechanism, the finished product and waste are clearly separated and collected. The sliding frame guide and roller pressing mechanism ensure that the waste is discharged in a directional manner without tangling, which simplifies the subsequent process, improves the efficiency of on-site management, and reduces the intensity of manual intervention.

[0037] The technical solution of the present invention will now be clearly and completely described 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.

[0038] Example 1: Please refer to the appendix. Figure 1 - Appendix Figure 8 This invention provides a semi-automatic blister pack cutting and filling device, including a base plate 1. A support box 2 is fixedly connected to the upper surface of the base plate 1. A support assembly is fixedly connected to the upper surface of the support box 2. A hydraulic cylinder 11 is fixedly connected to the top of the support assembly. A slide plate 12 is fixedly installed at the output end of the hydraulic cylinder 11. A buffer assembly is installed on the lower surface of the slide plate 12. A lower pressure plate 24 is fixedly connected to the bottom end of the buffer assembly. A rubber pad 25 is fixedly connected to the lower surface of the lower pressure plate 24. A connecting block 1 is fixedly connected to the lower surface of the slide plate 12. 3. A cutting blade 14 is slidably connected inside the connecting block 13. A slot 15 is provided on the outer wall of the cutting blade 14. A cylinder 16 is fixedly connected inside the connecting block 13. A connecting shaft 17 is fixedly connected inside the cylinder 16. A cam handle 18 is rotatably connected to the outer wall of the connecting shaft 17. An insertion post 19 is provided on the outer wall of the cam handle 18. A limit ring 20 is fixedly connected to the outer wall of the insertion post 19. A spring 21 is provided inside the cylinder 16. A filling component is provided on the upper surface of the base plate 1. A receiving component is provided on the upper surface of the support box 2.

[0039] Specifically, the control panel 3 controls the coordinated operation of various mechanisms within the equipment, achieving precise control of the equipment's workflow and ensuring stable operation. This ensures that processes such as cutting, filling, heat sealing, and conveying are executed systematically according to the set program, making the entire machine more stable and reliable. The hydraulic cylinder 11 drives the sliding plate 12 to move vertically downwards along the limit frame 10, synchronously driving the lower pressure plate 24 and the cutting blade 14 downwards, sequentially completing the pressing and cutting actions. This allows the two processes to be completed consecutively, improving processing efficiency. The rubber pad 25 at the bottom of the lower pressure plate 24 flexibly adheres to the film surface, achieving pre-pressing and fixing of the film before cutting to prevent displacement. Simultaneously, the flexible contact method avoids film... To prevent the material from being crushed or cracked, and to ensure the integrity of the finished product's appearance, the cutting blade 14 cuts and separates the sealed film material, dividing the continuous film material into individual blister products. This results in uniform product size and regular shape, meeting subsequent packaging and usage requirements. The cam handle 18 rotates around the connecting shaft 17, changing the extrusion position and enabling rapid control of the extension and retraction of the insert 19, as well as quick unlocking and locking of the cutting blade 14. This makes blade replacement easier and faster. The connecting shaft 17 supports the stable rotation of the cam handle 18, ensuring smooth rotation and accurate positioning, allowing for smooth and unobstructed assembly and disassembly of the cutting blade 14. The cylinder 16 serves to install the connecting shaft 17 and the insert 19. The function of spring 21 and pin 9 is to provide sliding guidance for the insert 19 and ensure the stable extension and contraction of spring 21, providing reliable structural support for the quick-change tool mechanism. Insert 19 engages or disengages from the slot 15 on the cutting blade 14, achieving quick locking and releasing of the cutting blade 14, enabling tool-less quick assembly and disassembly of the tool, significantly reducing downtime during tool changes. Limit ring 20 slides, compresses, or releases spring 21 inside cylinder 16, storing and releasing elastic force and assisting in the automatic reset of insert 19, ensuring stable engagement of insert 19 into slot 15, and firmly fixing the cutting blade 14. Connecting block 13 installs and guides the cutting blade 14, providing support for the cutting blade 14. The support box 2 provides positioning support, ensuring the straight and precise up-and-down movement of the cutting blade 14, improving the punching position accuracy. It also serves to mount components such as the support frame 4, fixing block 27, and L-shaped plate 30, providing a stable mounting foundation for the various mechanisms in the middle of the equipment while protecting internal components and improving overall machine stability. The base plate 1 supports the entire structure of the support box 2, receiving assembly, filling assembly, and conveying mechanism, ensuring the weight of the entire machine is supported and preventing shaking or displacement during operation. It provides a solid and reliable mounting foundation for the entire system. Each servo motor is equipped with a high-precision encoder to provide real-time feedback of rotor position information to the control panel 3, achieving closed-loop control and ensuring precise synchronization of the actions at each station.The servo synchronous drive system links encoder signals with the operating parameters of the filling assembly, heat sealing machine 35, and cutting mechanism to dynamically adjust the film conveying speed and the triggering timing of each process, thereby improving the finished product qualification rate.

[0040] Please see the appendix Figure 5 The buffer assembly includes a telescopic rod 22, the top end of which is fixedly connected to the lower surface of the slide plate 12, the bottom end of which is fixedly connected to the upper surface of the lower pressure plate 24, and a second spring 23 is provided on the outer wall of the telescopic rod 22. One end of the second spring 23 is fixedly connected to the lower surface of the slide plate 12, and the other end is fixedly connected to the upper surface of the lower pressure plate 24.

[0041] Specifically, the buffer assembly composed of telescopic rod 22 and spring 23 generates elastic deformation and absorbs the impact force of punching, thereby maintaining the pressure of the pressure plate and reducing the transmission of equipment vibration. This makes the cutting knife 14 punch more smoothly, resulting in a flat, smooth, burr-free, and edge-free blister cut, significantly improving the cutting quality. The telescopic rod 22 supports the lower pressure plate 24 to move smoothly up and down, achieving the effect of working with the buffer structure to maintain pressure balance. The spring 23 absorbs the punching vibration and impact, thus protecting the knife, film material, and equipment structure, and improving the cutting stability.

[0042] Please see the appendix Figure 1 and attached Figure 7 The filling assembly includes a support frame 36, a guide plate 38 fixedly connected to the outer wall of the support frame 36, a storage box 39 fixedly connected to the top of the support frame 36, a feed valve 40 fixedly connected to the top of the guide plate 38, a servo motor 41 fixedly connected to the upper surface of the guide plate 38, a rotating shaft 42 fixedly installed at the output end of the servo motor 41, the outer wall of the rotating shaft 42 rotatably connected through the top of the storage box 39, an auger 43 fixedly connected to the outer wall of the rotating shaft 42, and a filling head 44 fixedly connected to the bottom of the storage box 39.

[0043] Specifically, the support frame 36 serves to install the guide plate 38, storage bin 39, and other filling-related structures, providing stable support for the filling mechanism and ensuring a continuous and uniform filling process. The guide plate 38 guides the material into the storage bin 39, ensuring smooth, unobstructed, and residue-free material transport and stable material supply. The storage bin 39 temporarily stores materials to be filled, ensuring a continuous supply of materials to the filling station and uninterrupted filling, meeting the needs of continuous production. The feed valve 40 controls the speed and flow rate of material entering the storage bin 39, stabilizing the amount of material in the bin and preventing excessive or insufficient material from affecting filling accuracy. The servo motor 41 drives the rotating shaft 42 and the auger 43 to rotate, stably pushing the material inside the storage bin 39 to the filling head 44 according to the preset dosage, completing the quantitative measurement. The filling effect ensures consistent filling volume within each blister pack, improving product quality stability from the source. The anti-drift powder component drives the negative pressure adsorption and airflow shielding structure, suppressing material dispersion during filling. This ensures a clean production environment, reduces material loss, and improves raw material utilization. The rotating shaft 42 drives the auger 43 to rotate at a uniform speed, smoothly and quantitatively pushing the material to the filling head 44, ensuring accurate and uniform filling dosage. The filling head 44 precisely injects the material into the blister cavity, achieving quantitative filling, accurate filling, and preventing spillage or misalignment. The anti-drift powder component includes an anti-drift powder baffle, a negative pressure adsorption module, and an airflow shielding structure. All components work synchronously with the filling mechanism, effectively suppressing powder dispersion during filling through the triple action of physical barriers, airflow barriers, and negative pressure adsorption.

[0044] Please see the appendix Figure 4 The receiving assembly includes a receiving box 5, the outer wall of which is fixedly connected to the upper surface of the support box 2, a connecting frame 6 is fixedly connected to the lower surface of the support assembly, and a sliding frame 7 is fixedly connected to the inner wall of the connecting frame 6.

[0045] Specifically, the receiving box 5 serves to centrally collect finished blister packs, facilitating unified sorting, transfer, and counting by staff, preventing finished products from being scattered or lost, and simplifying subsequent processes. The connecting frame 6 and sliding frame 7 guide the directional movement of cutting waste, ensuring that waste smoothly enters the conveying mechanism without tangling or piling up, keeping the cutting station clean, and ensuring continuous operation of the equipment.

[0046] Please see the appendix Figure 1 - Appendix Figure 4The support assembly includes a support frame 4, the bottom of which is fixedly connected to the upper surface of the support box 2. The upper surface of the support box 2 is provided with a material receiving assembly. The upper surface of the support frame 4 is fixedly connected to a guide plate 8 and a limiting frame 10. The guide plate 8 and the support frame 4 are both provided with pre-drilled holes 9. The outer wall of the hydraulic cylinder 11 is fixedly connected to the top of the limiting frame 10. The outer wall of the connecting frame 6 is fixedly connected to the lower surface of the support frame 4.

[0047] Specifically, the guide plate 8 supports the blister pack, ensuring smooth cutting and preventing finished product accumulation, jamming, and damage from impacts. The pre-drilled holes 9 allow the film material and finished products to pass through smoothly, avoiding structural interference and ensuring smooth conveying and unloading. The support frame 4 installs and fixes the guide plate 8, the limit frame 10, and the hydraulic cylinder 11, providing stable support for the entire cutting mechanism, ensuring stable and reliable cutting operations, and improving the overall structural strength of the equipment.

[0048] Please see the appendix Figure 1 - Appendix Figure 8 The inner wall of the slide plate 12 is slidably connected to the outer wall of the limit frame 10. The outer wall of the insert post 19 is slidably connected to the inner wall of the cylinder 16. The outer wall of the limit ring 20 is slidably connected to the inner wall of the cylinder 16. The end of the insert post 19 is slidably connected to the inner wall of the slot 15. One end of the spring 21 is fixedly connected to the outer wall of the limit ring 20, and the other end is fixedly connected to the inner wall of the cylinder 16. The outer wall of the cutting blade 14 is slidably connected to the inner wall of the lower pressure plate 24.

[0049] Specifically, the limit bracket 10 constrains the movement direction of the slide plate 12, ensuring that the slide plate 12 only moves vertically and does not sway or tilt. This allows the lower pressure plate 24 and the cutting blade 14 to move in precise downward positions, improving cutting consistency. The slot 15 and the insert 19 work together to quickly position and lock the blade, facilitating disassembly and assembly, shortening blade change time, and improving equipment utilization. The spring 21 pushes the limit ring 20 and the insert 19 to reset, allowing the insert 19 to retract when unlocking and extend smoothly when locking, further enhancing the convenience and reliability of the blade changing mechanism.

[0050] Please see the appendix Figure 1 - Appendix Figure 3The upper surface of the support box 2 is fixedly connected to a fixing block 27 and an L-shaped plate 30. The inner top wall of the L-shaped plate 30 is fixedly connected to a hydraulic cylinder 31. The output end of the hydraulic cylinder 31 is fixedly provided with a roller 32. The bottom end of the L-shaped plate 30 is fixedly connected to a servo motor 33. The output end of the servo motor 33 is fixedly provided with a conveying roller 34. The outer wall of the conveying roller 34 is rotatably connected through the inside of the L-shaped plate 30. The inside of the fixing block 27 is rotatably connected to a conveying roller 28 and a limiting roller 29.

[0051] Specifically, the conveying roller 28 and the limiting roller 29 on the fixed block 27 drive the film material forward smoothly, maintaining constant film tension and preventing loosening, shifting, and wrinkling, thus providing stable conditions for subsequent high-precision cutting. The L-shaped plate 30 serves to install the hydraulic cylinder 31, servo motor 33, and conveying roller 34, providing reliable support for the waste material conveying mechanism and ensuring stable waste material discharge. The hydraulic cylinder 31 drives the roller 32 to press the waste material downward, firmly holding it in place and preventing slippage or shifting during conveying, ensuring stable and reliable waste material conveying. The servo motor 33 drives the conveying roller 34 to rotate, continuously conveying the waste material pressed by the roller 32 outward, achieving automatic waste cleaning and preventing waste accumulation from affecting normal production. The roller 32, in conjunction with the conveying roller 34, clamps and conveys the waste material, allowing it to be discharged quickly and smoothly from the outside of the equipment.

[0052] Please see the appendix Figure 8 A heat sealing machine 35 and a support plate 37 are fixedly connected to the upper surface of the base plate 1, and a guide wheel 45 is rotatably connected inside the support plate 37; a servo motor 46 is fixedly connected to the outer wall of the support plate 37, and an unwinding roller 26 is fixedly installed at the output end of the servo motor 46, and the outer wall of the unwinding roller 26 is rotatably connected inside the support plate 37.

[0053] Specifically, the heat sealing machine 35 is existing technology and can be a DPH series roller-type mesh heat sealing blister packaging machine from Zhejiang Jiangnan Pharmaceutical Machinery Co., Ltd., but is not limited to this series. The heat sealing machine 35 seals the film material, and the support plate 37 serves to install the guide wheel 45, unwind roller 26, and servo motor 46, achieving stable support for the film unwinding and conveying mechanism, ensuring smooth film conveying. The unwind roller 26 unfolds and conveys the pre-formed blister film material, achieving a continuous supply of film material to the production line and ensuring continuous operation of each process. The servo motor 46 drives the unwinding roller 26 to rotate, achieving the effect of stably conveying the pre-formed blister film material along the guide wheel 45 to the filling station. This provides a continuous and stable supply of film material for subsequent quantitative filling, ensuring that there will be no interruption in the supply of material to the entire production line. The guide wheel 45 also drives the blister film material to be conveyed in a directional manner, which reduces film friction and avoids the film material from shifting, wrinkling, or running off-track during the conveying process. This improves the stability and positioning accuracy of the film material conveying, providing a good foundation for subsequent filling and cutting.

[0054] Example 2: Please refer to the appendix. Figure 1 - Appendix Figure 9 This invention provides a method for using a semi-automatic blister pack cutting and filling equipment, comprising the following steps:

[0055] S1. By issuing control commands through the control panel 3 of the operating equipment, the servo motor 46 is started, and the servo synchronous transmission system is used to smoothly transport the film material that has completed the forming process to the filling component of the filling station, so as to prepare for the subsequent filling process.

[0056] S2. After the film material arrives, start the servo motor 41 to complete the precise feeding operation of the material according to the preset filling dosage. At the same time, the anti-dust component and the filling component operate synchronously.

[0057] S3. After the film material is filled, it is conveyed to the heat sealing machine 35 for heat sealing. After sealing, the hydraulic cylinder 11 is started, and the cutting mechanism is driven by the hydraulic cylinder 11 to cut the sealed film material to a fixed length to form an independent finished product.

[0058] S4. After the qualified finished film material is cut, it is collected in a unified and orderly manner by the material receiving component; at the same time, the hydraulic cylinder 31 and the servo motor 33 are started to stably transport the corner waste generated during the cutting process to the outside and discharge it, so as to realize the separation of finished product and waste material.
