Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical packaging machinery technology, and in particular to a double-row soft packaging infusion bag making device. Background Technology
[0002] The double-row flexible packaging infusion bag making device is used to produce flexible packaging bags for infusion. It can make bags in two rows at the same time, improving production efficiency. The device is usually composed of forming components required for bag making. It can process materials such as film into flexible packaging bags that meet the requirements of infusion. Its operation is relatively convenient and can guarantee the specifications and quality of bag making to a certain extent. It is suitable for infusion packaging production scenarios and provides support for the packaging of infusion products. It focuses on the related operations and functions of the bag making process.
[0003] When the double-row flexible packaging infusion bag making device is working, the unwinding mechanism first unfolds the film material, which is then positioned by the guide roller and enters the heating device. The film is softened by electric heating or infrared heating. Then the forming mold closes and the softened film is hot-pressed to form a double-row bag cavity. At the same time, the sealing mechanism heat-seals the edge of the bag, and the cutting device cuts it according to specifications. Under the action of the traction mechanism, the formed bag is conveyed to the discharge end. The whole process achieves continuous bag making through the coordination of mechanical transmission and temperature control system, ensuring the bag specifications and sealing performance.
[0004] In existing technologies, some double-row flexible packaging infusion bag making devices experience film misalignment during operation, resulting in uneven stress on the film during the heating and forming stage. This leads to irregular shapes and dimensional deviations in the resulting infusion bag cavity, making it difficult to precisely align the bag edges during heat sealing, resulting in problems such as incomplete sealing and leakage. Therefore, a double-row flexible packaging infusion bag making device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a double-row soft packaging infusion bag making device, which aims to improve the existing double-row soft packaging infusion bag making devices. During operation, the film will shift, resulting in uneven stress on the film during the heating and forming stage. This causes the shape of the infusion bag cavity to be irregular and the size deviation to exceed the standard range. It is also difficult to accurately align the bag edge during heat sealing, resulting in problems such as poor sealing and leakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A double-row soft packaging infusion bag making device includes a conveyor table. A guide rail is fixedly connected to the top of the conveyor table. Two fixed blocks are slidably connected to the top of the guide rail. A support plate is fixedly connected inside each of the two fixed blocks. A motor is fixedly connected to the far side of the support plate. A drive wheel is fixedly connected to the drive end of the motor. A belt is rotatably connected to the outer side of the drive wheel. A driven wheel is rotatably connected to the other end of the belt. A rotating shaft is fixedly connected inside the driven wheel. A connecting rod is fixedly connected to the other end of the rotating shaft. Two transmission rods are rotatably connected to the adjacent side of the connecting rod. A connecting plate is rotatably connected to the other end of the two transmission rods. A disc rod is fixedly connected to the adjacent side of the connecting plate. Two limit blocks are threaded inside the guide rail. A disassembly assembly for easy mold replacement is provided on the right side of the conveyor table. As a further description of the above technical solution: The disassembly assembly includes an operating platform. The left side of the operating platform is fixedly connected to the right side of the conveyor platform. A lifting platform is fixedly connected to the inner side of the operating platform. Multiple drive shafts are rotatably connected inside the lifting platform. A turntable is fixedly connected to the top of each of the multiple drive shafts. Ratchets are fixedly connected to the outer sides of each of the multiple drive shafts. Four corner blocks are fixedly connected to the outer sides of each of the multiple drive shafts. Two L-shaped rods are rotatably connected to the top of each of the four corner blocks. A clamping rod is rotatably connected to the other end of each of the two L-shaped rods. A mold block is installed at the bottom end of each clamping rod. Multiple pawls are fixedly connected to the top of the lifting platform. A lever is fixedly connected to the outer side of each of the multiple pawls. Multiple protective covers are fixedly connected to the top of the lifting platform. Spring pieces are fixedly connected inside each of the multiple protective covers. As a further description of the above technical solution: The outer side of the rotating shaft is rotatably connected to the inside of the support plate, and a slider is fixedly connected to the opposite side of the connecting plate. As a further description of the above technical solution: The slider is internally connected to a slide rail, and the far side of the slide rail is fixedly connected to the near side of the support plate. As a further description of the above technical solution: The other end of the limiting block is in contact with the outside of the fixing block, and the far side of the slider is slidably connected to the near side of the support plate; As a further description of the above technical solution: The outer side of the ratchet contacts the outer side of the pawl, and the outer side of the spring contacts the outer side of the lever; As a further description of the above technical solution: The lifting platform has multiple grooves inside, and the outer side of the clamping rod is slidably connected to the inside of the grooves; As a further description of the above technical solution: The protective cover has a sliding groove inside, and the outer side of the lever is slidably connected to the inside of the sliding groove.
[0007] This utility model has the following beneficial effects: 1. In this utility model, after the fixing block is moved into place, it is fixed by the limiting block. The raw material passes through the disc rod. The motor is started to drive the drive wheel to rotate. Through belt transmission, the driven wheel drives the connecting rod to rotate, which in turn drives the transmission rod to move. The connecting plate drives the disc rod to slide along the slide rail through the slider to limit the raw material. This ensures that the film moves stably during traction and forming, avoids size deviation and sealing misalignment caused by offset, reduces material waste and downtime for debugging, and ensures that the bag making accuracy meets the pharmaceutical packaging standards.
[0008] 2. In this utility model, the connecting post of the mold block is placed inside the clamping rod. Rotating the turntable drives the transmission shaft to rotate, causing the four corner blocks and the ratchet to move synchronously. The four corner blocks drive the L-shaped rod to convert the circular motion into linear motion, pushing the clamping rod to hold the mold block. At the same time, the ratchet stops rotating, and the pawl locks the ratchet tooth tip to fix the mold block. When disassembling, the lever is moved to disengage the pawl from the ratchet, and the turntable is rotated in the opposite direction to release the mold block. This simplifies the traditional bolt fixing method, shortens the mold change time, and improves the changeover efficiency and production continuity. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figures 2 to 4 This utility model provides an embodiment of a double-row soft packaging infusion bag making device, including a conveyor platform 1. The conveyor platform 1 is used to carry the material transfer during the infusion bag making process and provides an installation platform for other components. A guide rail 2 is fixedly connected to the top of the conveyor platform 1. The guide rail 2 provides a guiding path for the sliding of the fixed blocks 3, ensuring the linear motion accuracy of the fixed blocks 3 in the horizontal direction and ensuring the stability of the subsequent component movements. Two fixed blocks 3 are slidably connected to the top of the guide rail 2. The fixed blocks 3 are used to install support plates 4 and drive components, and can move laterally along the guide rail 2 to adjust the working range of the device. The support plates 4 are fixedly connected inside the two fixed blocks 3. The support plates 4 support components such as the motor 5 and the rotating shaft 9, ensuring the stability of the drive structure and providing installation positions for the slider 14 and the slide rail 15.
[0013] A motor 5 is fixedly connected to one side of the support plate 4. The motor 5 serves as a power source, driving the drive wheel 6 to rotate via its drive end, providing power input for the entire transmission process. The drive wheel 6 is fixedly connected to the drive end of the motor 5, and a belt 7 is rotatably connected to the outer side of the drive wheel 6. Through the belt 7, the rotational motion of the motor 5 is transmitted to the driven wheel 8, thus transmitting power. The driven wheel 8 is rotatably connected to the other end of the belt 7. A rotating shaft 9 is fixedly connected inside the driven wheel 8, connecting the driven wheel 8 to the connecting rod 10, converting the rotational motion of the driven wheel 8 into the oscillation of the connecting rod 10. The connecting rod 10 is fixedly connected to the other end of the rotating shaft 9, and the connecting rod 10 oscillates in a circular motion as the rotating shaft 9 rotates, driving the connecting plate 12 to move via a rotatably connected transmission rod 11.
[0014] Two transmission rods 11 are rotatably connected to adjacent sides of the connecting rod 10. A connecting plate 12 is rotatably connected to the other end of each transmission rod 11. The transmission rods 11 convert the oscillation of the connecting rod 10 into the linear reciprocating motion of the connecting plate 12, thus converting transmission and force. A disc rod 13 is fixedly connected to adjacent sides of the connecting plate 12. By adjusting a series of components, the disc rod 13 is moved to limit the movement of the raw material and prevent it from shifting. Two limiting blocks 16 are internally threaded onto the guide rail 2, which fix the selected fixed block 3. A disassembly assembly for easy mold replacement is provided on the right side of the conveyor table 1.
[0015] Reference Figure 1 , Figure 5 , Figure 6 The disassembly assembly includes an operating platform 17, whose left side is fixedly connected to the right side of the conveyor platform 1. The operating platform 17 provides an operating platform for the production of infusion bags. A lifting platform 18 is fixedly connected to the inner side of the operating platform 17, allowing for vertical lifting and lowering movement, which drives the mold block 25 to move, facilitating the production of infusion bags. Multiple drive shafts 19 are rotatably connected inside the lifting platform 18. As the core component for power transmission, the drive shafts 19 are connected to a turntable 20 at their top and have ratchet 21 and four corner blocks 22 fixed on their outer sides, which can transmit rotational motion to related components. The tops of the multiple drive shafts 19 are all fixedly connected to the turntable 20. By applying force to the turntable 20, a series of subsequent components are driven to move. Ratchets 21 are fixedly connected to the outer sides of multiple drive shafts 19, and four corner blocks 22 are fixedly connected to the outer sides of multiple drive shafts 19. Two L-shaped rods 23 are rotatably connected to the top of the four corner blocks 22, and clamping rods 24 are rotatably connected to the other ends of the two L-shaped rods 23. A mold block 25 is installed at the bottom end of the clamping rods 24.
[0016] Multiple pawls 27 are fixedly connected to the top of the lifting platform 18. The ratchet 21 and the pawls 27 work together. When the disc rod 13 fixes the mold block 25, the pawls 27 are engaged with the teeth of the ratchet 21. When the disc rod 13 clamps the mold block 25, the assembly is fixed. When the mold block 25 is disassembled, the pawls 27 can be disengaged from the ratchet 21 by moving the lever 28, thus releasing the locking state of the drive shaft 19. The levers 28 are fixedly connected to the outer sides of the multiple pawls 27. Multiple protective covers 26 are fixedly connected to the top of the lifting platform 18. The protective covers 26 and the turntable 20 work together to protect the internal components and prevent damage to the internal components due to external factors. The spring pieces 29 are fixedly connected inside the multiple protective covers 26 to provide elastic support for the pawls 27, so that they automatically reset and engage with the teeth of the ratchet 21 when no external force is applied, maintaining the locking effect.
[0017] Reference Figure 3 , Figure 4 , Figure 6The outer side of the rotating shaft 9 is rotatably connected to the inside of the support plate 4. This connection method ensures the stability of the rotating shaft 9 during operation, driving the connected components to move stably. A slider 14 is fixedly connected to the opposite side of the connecting plate 12. A slide rail 15 is slidably connected inside the slider 14. The opposite side of the slide rail 15 is fixedly connected to the adjacent side of the support plate 4. The support plate 4 provides stable support for the slide rail 15, allowing the slide rail 15 to guide the slider 14, enabling the slider 14 to move stably in a specified direction. The other end of the limiting block 16 contacts the outer side of the fixing block 3, and the opposite side of the slider 14 is slidably connected to the adjacent side of the support plate 4.
[0018] The outer side of the ratchet 21 contacts the outer side of the pawl 27. When the ratchet 21 starts to rotate under the drive of the drive shaft 19, the toothed structure on its outer side will contact the outer side of the pawl 27. Due to the special shape and installation method of the pawl 27, when the ratchet 21 rotates in a specific direction, the pawl 27 will slide on the tooth surface of the ratchet 21 and will not hinder the rotation of the ratchet 21. When the ratchet 21 attempts to rotate in the opposite direction, the pawl 27 will quickly engage in the tooth groove of the ratchet 21. The contact between the two generates strong resistance, preventing the ratchet 21 from rotating in the opposite direction, thereby realizing the unidirectional transmission of motion.
[0019] The outer side of the spring piece 29 contacts the outer side of the lever 28. The lifting platform 18 has multiple grooves inside, and the outer side of the clamping rod 24 is slidably connected to the inside of these grooves. The grooves provide a track for the movement of the clamping rod 24, allowing it to move in a specific direction, thereby fixing and releasing the mold block 25. The protective cover 26 has a sliding groove inside, and the outer side of the lever 28 is slidably connected to the inside of this groove. The sliding groove provides a clear path for the movement of the lever 28, ensuring that the lever 28 can only slide along the prescribed trajectory, preventing uncontrolled movement of the lever 28 due to external interference or other factors.
[0020] Working principle: Move the fixing block 3 to the appropriate position and fix it with the limiting block 16. Pass the raw material through the side of the disc rod 13. Start the motor 5. The motor 5 starts to move and drives the drive wheel 6 fixedly connected to its drive end to rotate. The movement of the drive wheel 6 is transmitted to the driven wheel 8 through the belt 7. The driven wheel 8 drives the connecting rod 10 to rotate through the rotating shaft 9. The movement of the connecting rod 10 drives the transmission rod 11 connected to it to move, so that the connecting plate 12 drives the disc rod 13 to slide on the outside of the slide rail 15 through the slider 14, thereby limiting the raw material and ensuring that the film raw material maintains a stable position in the traction, forming and other processes. This avoids problems such as bag size deviation and sealing misalignment caused by offset, reduces material waste and downtime for debugging, and ensures that the bag making accuracy meets the pharmaceutical packaging standards.
[0021] The connecting post of mold block 25 is placed inside mold block 25, and the turntable 20 is rotated. The movement of the turntable 20 drives the drive shaft 19 to rotate. The rotation of the drive shaft 19 drives the four corner blocks 22 and ratchet 21 to move simultaneously. The movement of the four corner blocks 22 drives the movement of the L-shaped rod 23. The L-shaped rod 23 converts its circular motion into the linear motion of the clamping rod 24, thereby clamping the mold block 25. At the same time, the movement of the ratchet 21 stops, and the pawl 27 is engaged with the tooth tip of the ratchet 21, thereby fixing the mold block 25. When disassembly is required, the lever 28 is moved to disengage the pawl 27 from the outside of the ratchet 21, and the turntable 20 is rotated in the opposite direction, driving a series of components to move in the opposite direction, thereby disassembling the mold block 25. This shortens the time for mold replacement or maintenance, avoids the cumbersome disassembly and assembly process caused by traditional bolt fixing, and enables operators to quickly complete the disassembly and installation of molds, improving the changeover efficiency and continuous production capacity of the production line.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
