Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of capping machine technology, and more specifically, to a rapid capping machine for the production of oral solutions. Background Technology

[0002] Oral solutions are clear liquid preparations made by dissolving raw drug substances in a suitable solvent for oral administration. Oral solutions have advantages such as small dosage, good taste, rapid absorption, and rapid onset of action, making them a type of drug that is easily accepted by patients.

[0003] After oral solutions are produced, they need to be filled into medicine bottles. After filling, the bottles need to be capped and sealed by a capping machine to ensure the long-lasting efficacy and convenient transportation. In existing capping machines, the caps are usually placed in a storage cylinder. The caps are controlled by the limiting holes to fall onto the medicine bottles one by one in the storage cylinder. Then, the lower pressing frame presses the cap onto the mouth of the medicine bottle. However, after the cap falls onto the mouth of the bottle by free fall, the cap is prone to tilting. This can easily cause damage to the cap when the lower pressing frame presses the cap, which can affect the capping effect. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a rapid capping machine for oral solution production, which solves the technical problem in the prior art where the cap tends to tilt on the bottle mouth after falling freely onto it, which can easily damage the cap when the lower presser compacts it, thus affecting the capping effect.

[0005] According to one aspect, at least one embodiment of this disclosure provides a rapid capping machine for producing oral solutions, including a frame with a conveying mechanism on the frame, and further including: a storage cylinder, a limiting frame, a straightening frame, a pressing mechanism, and a limiting mechanism. The storage cylinder is fixedly connected inside the frame and is located above the conveying mechanism. Two limiting frames are provided, and the two limiting frames are located at the bottom end of the storage cylinder via a swing mechanism.

The straightening frame is located inside the frame via a moving mechanism, and the moving mechanism is used to drive the straightening frame to straighten the bottle caps onto the bottle opening. The pressing mechanism is located inside the frame and above the straightening frame, and is used to strike the straightening frame to press the bottle caps tightly onto the bottle opening. The limiting mechanism is located inside the frame and is used to guide the medicine bottles during conveying.

[0006] To drive the two limiting frames to swing intermittently and control the bottle cap to fall intermittently, the swing mechanism includes: a swing rod, a drive plate, a fixed ring, a torsion spring, and a drive assembly. Two swing rods are provided, both rotatably connected to the frame. The two limiting frames are respectively fixedly connected to the two swing rods.

[0007] To drive the two swing arms to rotate, the drive assembly includes a drive block and a first electric cylinder. The drive block is located at the top of the two drive plates and contacts the top of the two drive plates. The first electric cylinder is mounted on the frame, and the output end of the first electric cylinder is fixedly connected to the drive block.

[0008] To control the alignment frame to fit onto the tilted bottle cap, the moving mechanism includes: a slider, a support spring, a lower pressure frame, and a second electric cylinder. A groove is provided on the frame, and the slider is slidably connected within the groove. Two support springs are provided; the opposite ends of the two support springs are fixedly connected to the slider, and the ends of the two support springs that are far apart from each other are fixedly connected to the inner wall of the groove. The lower pressure frame is slidably connected to the slider, and the alignment frame is fixedly connected to one end of the lower pressure frame. The second electric cylinder is installed on one side of the slider, and its output end passes through the slider and is fixedly connected to the lower pressure frame.

[0009] In order to stably press the bottle cap onto the bottle mouth, the pressing mechanism includes: a fixed frame, an eccentric wheel and a first motor. The fixed frame is fixedly connected to the machine frame, the eccentric wheel is rotatably connected inside the fixed frame, and the circumferential surface of the eccentric wheel contacts the aligning frame. The first motor is installed on one side of the fixed frame, and the output end of the first motor passes through the fixed frame and is fixedly connected to the eccentric wheel.

[0010] To ensure stable transport of medicine bottles, the transport mechanism includes: a transport shaft, a drive belt, and a second motor. There are two transport shafts, both of which are rotatably connected within the frame. The drive belt is connected between the two transport shafts. The second motor is mounted on one side of the frame, and its output end passes through the frame and is fixedly connected to one of the transport shafts.

[0011] To guide the medicine bottle during transport, the limiting mechanism includes a limiting rod, a drive screw, and a third motor.

[0027] like Figures 1-4 The diagram illustrates a rapid capping machine for producing oral solutions according to an embodiment of this disclosure. It includes a frame 1 with a conveying mechanism mounted on it, and further comprises a storage cylinder 2, a limiting frame 3, a straightening frame 4, a pressing mechanism, and a limiting mechanism. The storage cylinder 2 is fixedly connected within the frame 1 and is positioned above the conveying mechanism. Two limiting frames 3 are provided, and are positioned at the bottom of the storage cylinder 2 via a swing mechanism. The swing mechanism drives the two limiting frames 3 to open and close, controlling the bottle caps to fall onto each bottle opening. The straightening frame 4 is positioned within the frame 1 via a moving mechanism, which drives the straightening frame 4 to... The bottle cap is positioned on the bottle mouth. The pressing mechanism is located inside the frame 1 and above the positioning frame 4. It is used to strike the positioning frame 4 to press the bottle cap tightly onto the bottle mouth. The limiting mechanism is located inside the frame 1 to guide the medicine bottle during transport. The swinging mechanism drives the two limiting frames 3 to swing, thereby controlling the bottle cap to fall intermittently onto each medicine bottle passing the bottom of the storage cylinder 2. Through the cooperation between the moving mechanism and the pressing mechanism, the bottle cap that is tilted on the bottle mouth can be swung and pressed tightly onto the bottle mouth, thereby reducing the damage to the bottle cap caused by the tilt of the bottle cap and improving the efficiency and effect of the bottle cap pressing.

[0028] The swing mechanism includes: swing rods 5, drive plates 6, fixed rings 7, torsion springs 8, and a drive assembly. Two swing rods 5 are provided, both rotatably connected to the frame 1. Two limit frames 3 are fixedly connected to the two swing rods 5 respectively. Drive plates 6 are fixedly connected to each of the two swing rods 5, fixed rings 7 are fixedly connected to each of the two swing rods 5, and torsion springs 8 are sleeved on each of the two swing rods 5. The two ends of the two torsion springs 8 are fixedly connected to the fixed rings 7 and the frame 1 respectively. The drive assembly is mounted on the frame 1 and is used to drive the two swing rods 5 to rotate. The drive assembly includes: a drive block 9 and a first electric cylinder 10. 9 is located at the top of the two drive plates 6 and is in contact with the top of the two drive plates 6. The first electric cylinder 10 is mounted on the frame 1. The output end of the first electric cylinder 10 is fixedly connected to the drive block 9. The first electric cylinder 10 drives the drive block 9 to descend. When the drive block 9 descends, it pushes the two drive plates 6 to swing around the center of the swing rod 5. This causes the limit frame 3 to swing through the swing rod 5, thereby opening the bottom of the storage cylinder 2 and letting the bottle cap fall. Then, the torsion spring 8 rebounds the swing rod 5 and the limit frame 3, causing the two limit frames 3 to quickly return to their original positions, thereby controlling the bottle cap to fall intermittently onto the bottle mouth.

[0029] The moving mechanism includes: a slider 11, a support spring 12, a lowering frame 13, and a second electric cylinder 14. A groove is provided on the frame 1, and the slider 11 is slidably connected within the groove. Two support springs 12 are provided; the opposite ends of the two support springs 12 are fixedly connected to the slider 11, and the ends of the two support springs 12 that are far apart from each other are fixedly connected to the inner wall of the groove. The lowering frame 13 is slidably connected to the slider 11, and a leveling frame 4 is fixedly connected to one end of the lowering frame 13. The second electric cylinder 14 is installed on one side of the slider 11, and its output end passes through the slider 11 and is fixedly connected to the lowering frame 13. The lowering mechanism includes: a fixed frame 15 and an eccentric wheel. The first motor 16 and the first motor 17 are fixedly connected to the frame 1 and the fixed frame 15. The eccentric wheel 16 is rotatably connected inside the fixed frame 15. The circumferential surface of the eccentric wheel 16 contacts the straightening frame 4. The first motor 17 is installed on one side of the fixed frame 15. The output end of the first motor 17 passes through the fixed frame 15 and is fixedly connected to the eccentric wheel 16. The second electric cylinder 14 drives the lower pressing frame 13 to move, thereby moving the straightening frame 4 to the top of the bottle cap. The first motor 17 drives the eccentric wheel 16 to rotate, thereby striking the straightening frame 4. During the striking process, the straightening frame 4 can push the tilted bottle cap to the right and press the bottle cap firmly onto the bottle mouth.

[0030] The conveying mechanism includes a conveying shaft 18, a transmission belt 19, and a second motor 20. A support plate 24 is fixedly connected inside the frame 1. The top of the support plate 24 contacts the inner wall of the transmission belt 19. There are two conveying shafts 18, both of which are rotatably connected inside the frame 1. The transmission belt 19 is connected between the two conveying shafts 18. The second motor 20 is installed on one side of the frame 1. The output end of the second motor 20 passes through the frame 1 and is fixedly connected to one of the conveying shafts 18. The second motor 20 drives one of the conveying shafts 18 to rotate, and the transmission belt 19 drives the transmission between the two conveying shafts 18, thereby conveying the medicine bottle.

[0031] The limiting mechanism includes: a limiting rod 21, a drive screw 22, and a third motor 23. There are two limiting rods 21. One limiting rod 21 is fixedly connected to the frame 1, and the other limiting rod 21 is slidably connected to the frame 1 through a slide 25. The two ends of the drive screw 22 are rotatably connected to the limiting rod 21 and the slide 25, respectively. A screw hole is provided on the frame 1, and the drive screw 22 is threaded into the screw hole. The third motor 23 is installed on one side of the slide 25. The output end of the third motor 23 passes through the slide 25 and is fixedly connected to the drive screw 22. The third motor 23 drives the drive screw 22 to rotate. When the drive screw 22 rotates, it drives the slide 25 to move on the frame 1, thereby driving the limiting rod 21 to move. This adjusts the distance between the two limiting rods 21 and guides the medicine bottle during delivery through the limiting rods 21.

[0032] The working principle is as follows: When it is necessary to cap the medicine bottle, the bottle cap is first placed in the storage cylinder 2. Then, the first electric cylinder 10 drives the drive block 9 to descend. When the drive block 9 descends, it pushes the two drive plates 6 of the chain to swing around the center of the swing rod 5. This causes the swing rod 5 to drive the limit frame 3 to swing, thereby opening the bottom of the storage cylinder 2 and letting the bottle cap fall. Then, the torsion spring 8 rebounds the swing rod 5 and the limit frame 3, causing the two limit frames 3 to quickly return to their original positions. This controls the bottle cap to fall intermittently onto the bottle mouth. The second electric cylinder 14 drives the pressing frame 13 to move, thereby moving the straightening frame 4 above the bottle cap. The first motor 17 drives the eccentric wheel 16 to rotate, thereby striking the straightening frame 4. During the striking process, the straightening frame 4 can push the tilted bottle cap straight and press the bottle cap firmly onto the bottle mouth.
