Description

Technical Field

[0001] This invention relates to the field of air-cooling technology, specifically to an air-cooling system for an oral solution BFS production line. Background Technology

[0002] BFS (Blow / Fill / Seal) production lines are highly automated aseptic packaging technologies. They integrate the three core processes of plastic container blow molding, product filling, and container sealing into a single machine, completing these processes continuously in a sterile environment, minimizing human intervention and environmental exposure. This production line features in-line cleaning (CIP) and in-line sterilization (SIP) functions, complies with GMP standards in various countries, and is widely used in sterile pharmaceuticals, functional foods, and cosmetics, offering advantages such as high efficiency, energy saving, and environmental friendliness.

[0003] BFS (Blow-Filtration-Shipment) production lines integrate blow molding, filling, and sealing. For example, patent publication number CN117023087A describes a flipping mechanism for a BFS production line used to detect leaks in packaging. This mechanism includes a leak detector and a flipping device. The leak detector has an infeed conveyor belt and an outfeed conveyor belt installed on both sides, and both conveyor belts are double-track conveyors. The flipping device is installed at the end of the outfeed conveyor belt and includes a first clamping plate, a second clamping plate, a first rotating shaft, and a second rotating shaft. The first and second clamping plates are arranged one above the other, positioned between the two conveyor tracks of the outfeed conveyor belt. The first and second clamping plates can grip the material on the outfeed conveyor belt. After a leak test on the outer packaging of a medicine, the medicine is flipped 180 degrees and then a second leak test is performed. This ensures that every part of the medicine packaging is immersed in the liquid medicine, meeting the requirements for high-voltage discharge detection and preventing missed detections in certain areas.

[0004] During the production process of BFS equipment, after the container is shaped and filled in the mold, it separates from the mold and then descends during the mold reset (moving to below the preform extruder). At this time, the clamping structure fixed on one side of the mold moves to both sides of the container and removes the container during the next mold movement. However, in the above equipment and existing BFS equipment, during the time when the container is detached from the mold and does not contact the clamping structure, it is easy to come into direct contact with the hot air inside the equipment. For heat-sensitive oral solutions, this may cause loss of efficacy and is not conducive to improving product quality. Summary of the Invention

[0005] The purpose of this invention is to provide an air-cooled heat dissipation system for oral solution BFS production lines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wind-cooled heat dissipation system for an oral solution BFS production line, comprising a clamping component mounted on a mold, wherein the clamping component has a cooling channel for flowing cooling circulating liquid inside, and the end of the clamping component is connected to a liquid inlet and a liquid outlet, an air inlet is provided on the outside of the clamping component, and a fan mounting bracket for mounting a fan is provided on the outside of the air inlet, several air ducts are provided on both sides of the air inlet, and an air outlet is provided at the end of the air duct, with an opening at the upper end of the air outlet, two brackets are fixed on the outside of the clamping component, a slide rail is fixed on the upper end of the brackets, a sliding seat is slidably mounted on the slide rail, a hollow air box is fixed above the two sliding seats, an air inlet pipe is connected to both ends of the bottom of the air box, and the air inlet pipe is aligned with the corresponding air outlet, a synchronous limiting mechanism is provided between the two air boxes for fixing the position of the air box, and several air outlets are provided on the inner side of the air box.

[0007] Preferably, the synchronous limiting mechanism includes two vertical rods fixed to the outside of the two clamping members. The upper end of the vertical rod is provided with a first fixing pin, and the upper end of the two air boxes is fixed with a fixing member. The side end of the fixing member is rotatably provided with a synchronous disk, and the synchronous disk is provided with two symmetrically distributed second fixing pins. A synchronous connecting rod is connected between the first fixing pin and the corresponding second fixing pin, and the two ends of the synchronous connecting rod are respectively hinged to the first fixing pin and the second fixing pin.

[0008] Preferably, the synchronous limiting mechanism further includes two fixing plates fixed to the side of the fixing member. A sliding rod perpendicular to the clamping member is fixed on the outer side of the fixing plate. A sliding hole is opened at the upper end of the vertical rod, and the sliding rod is slidably inserted into the sliding hole at the corresponding position. A synchronous spring is sleeved on the sliding rod, and the two ends of the synchronous spring abut against the vertical rod and the fixing plate respectively.

[0009] Preferably, a groove is provided above the air outlet, and a first baffle is slidably disposed in the groove. A magnetic sheet is fixed on the side of the first baffle near the air inlet pipe, and the air inlet pipe is made of iron.

[0010] Preferably, the side end of the slide groove is provided with a vertical groove, the side end of the first baffle is fixed with a second baffle, and the second baffle is slidably disposed in the vertical groove. The side of the air outlet is provided with an air guide channel, which passes through the vertical groove, and the end of the air guide channel away from the air outlet is oriented towards the middle position of the two clamping members.

[0011] Preferably, the air outlet includes a rotating cover rotatably mounted on the side wall of the air box, and an air outlet pipe is connected to the end of the rotating cover. A rotating rod is fixed inside the rotating cover and passes through the air box. The rotating rod is rotatably connected to the side wall of the air box. A synchronization component is provided between multiple rotating rods, and a steering mechanism is provided on one of the rotating rods.

[0012] Preferably, the steering mechanism includes a first pulley fixed on a rotating rod, a mounting plate fixed to the outside of the air box, a first fixed rod and a second fixed rod fixed on the mounting plate, a second pulley and a third pulley rotatably mounted on the first fixed rod and fixed to each other, a first transmission belt installed between the second pulley and the first pulley, a fourth pulley and a gear rotatably mounted on the second fixed rod and fixed to each other, a second transmission belt installed between the third pulley and the fourth pulley, a conveying platform provided on one side of the clamping member, and a rack installed on the conveying platform, the rack meshing with the gear.

[0013] Preferably, the synchronization component includes a swing arm fixed on the rotating rod, and a crossbar is provided on the outside of the wind box, the crossbar being hinged to the end of the swing arm away from the rotating rod.

[0014] Preferably, a plurality of fixing frames are fixed on the inner side of the air box, and a fixing ring is fixed at one end of the fixing frame. The fixing ring is located on the inner side of the rotating cover and fits against the inner wall of the rotating cover near the air outlet pipe. An arc-shaped long slot is opened on the rotating cover, and the length of the arc-shaped long slot gradually decreases along the direction away from the mold.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Cooling airflow is provided by installing a fan. The airflow passes sequentially through the air inlet, air duct, air outlet, and air inlet pipe before entering the air box. Then, it blows from the air outlet onto the unclamped container. As the airflow passes through the inside of the clamping components, its temperature is reduced, thus achieving a cooling effect. Furthermore, the cooling fluid inside the clamping components is fully utilized before the container is clamped, improving energy efficiency.

[0017] At the same time, when the two clamping parts approach each other, they can compress the two synchronous springs simultaneously. The pressure of the two synchronous springs on the fixed plate is the same, which can further ensure that the fixed parts are in a fixed position, making the equipment run more smoothly. Moreover, the direction of the two slide rods is fixed, which can prevent the fixed parts from deflecting along the axis of the synchronous disc, thereby preventing the equipment from jamming.

[0018] Moreover, when the air outlet is aligned with the air inlet pipe, the second baffle blocks the middle of the air guide channel and cuts off the airflow, allowing all the airflow to enter the air box through the air outlet and exit the container through the air nozzle, thus improving the airflow utilization effect. When the air outlet is separated from the air inlet pipe (the clamping parts clamp the two sides of the container, making it difficult for the air nozzle to blow onto the surface of the container), the second baffle moves away, and the first baffle blocks the upper end of the baffle air outlet, allowing the airflow to blow towards the container through the air guide channel, making full use of the cooling airflow.

[0019] In addition, the air inside the air box is blown out through the rotating cover and the air outlet pipe. The rotating mechanism drives the rotating rod to rotate, and the rotating rod drives the rotating cover to rotate synchronously, thereby changing the direction of the air outlet pipe. During the movement of the clamping part, the air blowing direction is always towards the container.

[0020] In addition, when the clamping component is below the filling station, all the air outlets are turned on to cool the inner container. However, when the clamping component is close to the conveying platform, the rotating cover deflects. At this time, the air outlets that are farther away from the mold will have their air outlets diverge from the arc-shaped slot earlier, thus concentrating the air force on the air outlets that are closer to the mold, achieving the effect of air gathering and improving the air cooling effect.

[0035] 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.

[0036] like Figures 1-13 As shown, the present invention provides a technical solution: an air-cooled heat dissipation system for an oral solution BFS production line, including a clamping member 2 mounted on a mold 1. The clamping member 2 has a cooling channel 3 inside for flowing cooling circulating liquid, and an inlet and an outlet are connected to the end of the clamping member 2. An air inlet 4 is provided on the outer side of the clamping member 2, and a fan mounting bracket 12 for mounting a fan is provided on the outer side of the air inlet 4. Several air ducts 5 are provided on both sides of the air inlet 4, and an air outlet is provided at the end of each air duct 5. The upper end of the air outlet 6 is open. Two brackets 7 are fixed on the outside of the clamp 2. The upper end of the bracket 7 is fixed with a slide rail 8. A sliding seat 10 is slidably mounted on the slide rail 8. A hollow air box 9 is fixed above the two sliding seats 10. Both ends of the bottom of the air box 9 are connected to an air inlet pipe 11, and the air inlet pipe 11 is aligned with the corresponding air outlet 6. A synchronous limiting mechanism is set between the two air boxes 9 to fix the position of the air box 9. Several air outlets are evenly distributed on the inner side of the air box 9.

[0037] It is important to note that cooling airflow is provided by installing a fan. The airflow passes sequentially through the air inlet 4, air duct 5, air outlet 6, and air inlet pipe 11 before entering the air box 9. Then, it blows from the air outlet onto the unclamped container. As it passes inside the clamping member 2, the airflow temperature is reduced, thus achieving a cooling effect. Furthermore, the cooling circulating fluid inside the clamping member 2 can be fully utilized before the clamping member 2 clamps the container, improving energy efficiency. When the clamping member 2 clamps the container as the mold 1 moves, the two air boxes 9 remain stationary (not close to each other) under the action of the synchronous limiting mechanism, preventing collisions with the grippers of the conveying structure (which clamp the container from above) during subsequent movement.

[0038] like Figure 5 As shown, the synchronous limiting mechanism includes two vertical rods 15 fixed to the outside of the two clamping members 2. The upper end of the vertical rod 15 is provided with a first fixing pin, and the upper end of the two air boxes 9 is fixed with a fixing member 13. The side end of the fixing member 13 is rotatably provided with a synchronous disk 14, and the synchronous disk 14 is provided with two symmetrically distributed second fixing pins. The first fixing pin and the corresponding second fixing pin are connected by a synchronous connecting rod 16, and the two ends of the synchronous connecting rod 16 are respectively hinged to the first fixing pin and the second fixing pin.

[0039] It should be noted that the two air boxes 9 are fixed by the fixing member 13 to keep them fixed to each other. When the two clamping members 2 move closer or separate synchronously with the mold 1, the synchronous plate 14 will rotate under the action of the synchronous connecting rod 16 and keep the fixing member 13 in the middle position of the two clamping members 2. The fixing member 13 and the two air boxes 9 remain stationary. When the clamping members 2 move, the slide rail 8 moves relative to the sliding seat 10 and will not hinder the clamping effect of the clamping members 2.

[0040] like Figure 5 As shown, the synchronous limiting mechanism also includes two fixing plates 17 fixed to the side of the fixing member 13. A sliding rod 18 perpendicular to the clamping member 2 is fixed on the outside of the fixing plate 17. A sliding hole is opened at the upper end of the vertical rod 15, and the sliding rod 18 is slidably inserted into the sliding hole at the corresponding position. A synchronous spring 19 is sleeved on the sliding rod 18, and the two ends of the synchronous spring 19 abut against the vertical rod 15 and the fixing plate 17 respectively.

[0041] It should be noted that when the two clamping parts 2 are brought close together, they can compress the two synchronous springs 19 simultaneously. The pressure of the two synchronous springs 19 on the fixed plate 17 is the same, which can further ensure that the fixed part 13 is in a fixed position, making the equipment run more smoothly. Moreover, the direction of the two slide rods 18 is fixed, which can prevent the fixed part 13 from deflecting along the axis of the synchronous disc 14, thereby preventing the equipment from jamming.

[0042] like Figure 9As shown, a sliding groove 20 is provided above the air outlet 6, and a first baffle 21 is slidably arranged in the sliding groove 20. A magnetic sheet 22 is fixed on the side of the first baffle 21 near the air inlet pipe 11, and the air inlet pipe 11 is made of iron.

[0043] It should be noted that when the clamp 2 moves inward, the air inlet pipe 11 gradually moves away from the air outlet 6. At this time, the magnetic sheet 22 is attracted to the air inlet pipe 11 and moves with the air inlet pipe 11 to directly above the air outlet 6, blocking the air outlet 6 and preventing airflow from flowing out of the air outlet 6.

[0044] like Figure 9 As shown, a vertical groove 23 is provided on the side end of the slide 20, and a second baffle 24 is fixed on the side end of the first baffle 21. The second baffle 24 is slidably disposed in the vertical groove 23. An air guide channel 25 is provided on the side of the air outlet 6. The air guide channel 25 passes through the vertical groove 23, and the end of the air guide channel 25 away from the air outlet 6 is directed toward the middle position of the two clamping members 2.

[0045] It should be noted that when the air outlet 6 is aligned with the air inlet pipe 11, the second baffle 24 blocks the airflow in the middle of the air guide channel 25, allowing all the airflow to enter the air box 9 through the air outlet 6 and exit the container through the air nozzle, thus improving the airflow utilization effect. When the air outlet 6 is separated from the air inlet pipe 11 (the clamping part 2 clamps the two sides of the container, making it difficult for the air nozzle to blow onto the surface of the container), the second baffle 24 moves away, and the first baffle 21 blocks the upper end of the baffle air outlet 6, allowing the airflow to blow towards the container through the air guide channel 25, making full use of the cooling airflow.

[0046] like Figure 10 and Figure 12 As shown, the air outlet includes a rotating cover 26 rotatably mounted on the side wall of the air box 9, and an air outlet pipe 27 is connected to the end of the rotating cover 26. A rotating rod 28 is fixed inside the rotating cover 26, and the rotating rod 28 passes through the air box 9 and is rotatably connected to the side wall of the air box 9. A synchronization component is provided between multiple rotating rods 28, and a steering mechanism is provided on one of the rotating rods 28.

[0047] It should be noted that the air inside the air box 9 is blown out through the rotating cover 26 and the air outlet pipe 27. The rotating mechanism drives the rotating rod 28 to rotate, and the rotating rod 28 drives the rotating cover 26 to rotate synchronously, thereby changing the direction of the air outlet pipe 27. During the movement of the clamping part 2, the air blowing direction is always kept towards the container.

[0048] like Figure 1 and Figure 11As shown, the steering mechanism includes a first pulley 32 fixed on a rotating rod 28. A mounting plate 29 is fixed to the outside of the air box 9. A first fixing rod 30 and a second fixing rod 31 are fixed on the mounting plate 29. A second pulley 33 and a third pulley 34 are rotatably mounted on the first fixing rod 30 and are fixed to each other. A first transmission belt is installed between the second pulley 33 and the first pulley 32. A fourth pulley 35 and a gear 36 are rotatably mounted on the second fixing rod 31 and are fixed to each other. A second transmission belt is installed between the third pulley 34 and the fourth pulley 35. A conveying platform 37 is provided on one side of the clamping member 2, and a rack 38 is mounted on the conveying platform 37. The rack 38 meshes with the gear 36.

[0049] It should be noted that when the clamping member 2 clamps the container and moves, the gear 36 moves and rotates along the rack 38. The rotation of the gear 36 drives the rotating rod 28 to rotate through the rotation of the first transmission belt and the second transmission belt. Moreover, the transmission ratio is reduced through the transmission components, ensuring that the rotating rod 28 only deflects at a small angle throughout the entire movement of the clamping member 2, thereby ensuring that it always faces the container.

[0050] like Figure 4 and Figure 10 As shown, the synchronization component includes a swing arm 39 fixed on the rotating rod 28, and a crossbar 40 is provided on the outside of the wind box 9. The crossbar 40 is hinged to the end of the swing arm 39 away from the rotating rod 28.

[0051] It should be noted that the crossbar 40 is hinged to multiple swing arms 39 at the same time. When one of the swing arms 28 deflects, all the swing arms 28 will rotate synchronously.

[0052] like Figure 12 and Figure 13 As shown, several fixing brackets 41 are fixed on the inner side of the air box 9. A fixing ring 42 is fixed at one end of the fixing bracket 41. The fixing ring 42 is located on the inner side of the rotating cover 26 and fits against the inner wall of the rotating cover 26 near the air outlet pipe 27. An arc-shaped long slot 43 is opened on the rotating cover 26, and the length of the arc-shaped long slot 43 gradually decreases along the direction away from the mold 1.

[0053] It should be noted that all rotating covers 26 rotate at the same angle when the clamping member 2 moves. When the clamping member 2 is below the filling station, all air outlets 27 are opened to cool the inner container. However, when the clamping member 2 approaches the conveying platform 37, the rotating covers 26 deflect. At this time, the air outlets farther away from the mold 1 will have their air outlets 27 diverge from the arc-shaped long slot 43 earlier (because the arc-shaped long slot 43 is shorter), thus concentrating the air force on the air outlets closer to the mold 1, achieving a wind-gathering effect and improving the air-cooling effect.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
